Empirically Supported Principles versus Treatments Prevents Purple Hat Therapies having to support this claim anxiety symptoms eyes buy cheap lexapro 20mg line. But the authors will attribute success to the inert component, in this case wearing the purple hat, because that makes the treatment new and therefore eligible for publication, grant support, tenure, promotion, and fee training opportunities. Variations on how to implement empirically supported principles most effectively can and should continue. Optimal therapeutic outcomes require that dimensions of diversity, individual differences in problem presentation, and cultural issues be addressed. This focus on principles will provide clinicians with theoretical guidance when they need to tailor treatments, as was done when behavior therapy began. Claims can be made that this new therapy works because of the inert component without ever Clinical Practice We now turn to the very large pink elephant that has been sitting so patiently with us. Tryon, Jonathan Hoffman, and Dean McKay think that we have good news here based primarily on the personality simulations by Read and Miller (2002) and Read et al. These simulations enable us to get past the horse race comparison of interventions to the far more substantive issue of what changes as a result of therapy. Exposure therapy (Craske, Treanor, Conway, Zbozniak, & Vervliet, 2014; Payne, Ellard, Farchione, Fairholme, & Barlow, 2014) and its variants are currently the bestdocumented procedures for doing this. For example, Martell, Dmidjian, and HermanDunn (2010) recommended that depressed patients return to behaviors that they have terminated such as doing the dishes. Chadwick and Lowe (1990) developed a treatment protocol for delusions in patients with schizophrenia that involved systematically verifying perceptual and cognitive disturbances, that is, creating dissonance between what they think and what they can actually verify (see also Jahar et al. We can probably all agree that, as men and women of science, it is important that we are able to provide natural science explanations for how and why our empirically supported treatments work. All of these stakeholders want scientific explanations for why our treatments work. Behavior therapists once customized treatments to individual clients (see Tryon, 2014c, pp. The challenge for psychology is, and has always been, to explain how mind emerges from brain. Therefore, our ability to explain how and why our treatments work comes down to explaining how learning and memory work in the context of our therapies. Neuroscience discovered and has repeatedly verified the experiencedependent neuroplasticity mechanisms that enable learning and memory. Doing psychology with networks also begins to conceptually bridge the psychobiology gap-how psychology impacts biology including diseases of all kinds. Our effective brainchanging therapies differ mainly in what is to be learned and how to teach it. These are procedural details that need not divide us into competing and conflicting schools and camps. Practicing clinicians are more likely to incorporate these principles into their clinical practice than they are to acquire and become competent in a large and growing number of manualized interventions. Obtaining this degree of cooperation would be a welcome change from our present adversarial relationships. This may be true and maybe their interventions effectively activate the experiencedependent neuroplasticity mechanisms mentioned above. It is unlikely that all methods are equally effective in activating the experiencedependent neuroplasticity mechanisms that drive learning and memory, just as it is unlikely that all methods of teaching anything to everyone are equally effective. Research regarding methods and outcomes is still needed but it can now be directed by principles. The call by Kazdin and others for natural science mechanism information is compelling because it requires us to think about psychology and behavior in physical terms that are fully consilient with neuroscience rather than in mental terms, as we have done for so long. The neural network approach to learning and memory provides more such mechanism information than any other theoretical orientation currently available to us. For practitioners, the essential concepts to communicate at this point are: (a) neural network impediments or insufficiencies engender 474 Warren W. Tryon, Jonathan Hoffman, and Dean McKay dissonances that create pressures on individuals and/or systems to restore consonance(s), or escape or avoid said dissonances; (b) psychopathology, or maladaptation, occurs when dissonances cannot be adaptively ameliorated or tolerated, or when consonances are maladaptive. The massive complexity of neural network, physiological, and environmental interactions (Kendler, 2013) explains the diversity within and between psychopathological conditions, as presently classified or examined ipsatively. Our training and dissemination efforts can now focus on a few neural network properties that constitute natural science principles that can be used to customize treatments to clients instead of continuing to plead with practitioners to learn and use a large and ever growing number of manuals. Network models enable us to close the psychobiology and biopsychology gaps by explaining how braininspired network models learn and form memories in natural science terms.

It is usually negative in the oral mu cosal type anxiety 25 mg zoloft discount 5 mg lexapro visa, but may be seen in cases with plasmacytic differentiation. Prognosis and predictive factors the prognosis is generally poor; more than three quarters of patients die of the disease, with a median survival of 611 months 578,2755. Secretome analysis has revealed pro teins involved in inflammation, immune response, and cell cycle and growth; structural proteins; and other proteins 1385. Localization the most common sites are the pleural, pericardial, and peritoneal cavities. The disease also occurs in the absence of immunodeficiency, usually in elderly pa tients, both men and women 3946. Patients typically present with ef fusions in the absence of lymphadenopathy or organomegaly. Microscopy In cytocentrifuge preparations, the cells exhibit a variety of appearances, rang ing from large immunoblastic or plasmaPrimary effusion lymphoma 323 blastic cells to cells with more-anaplastic morphology. The cytoplasm can be abundant and is deeply basophilic, with vacuoles in occasional cells. The cells often ap pear more uniform in histological sec tions than in cytospin preparations 110, 955,2803). Pleomorphic large cells may have a Hodgkin-like appearance, necessitating differentiation from classic Hodgkin lymphoma. There may be in volvement of endothelial-lined lymphatic or vascular channels, and cases resem bling intravascular lymphoma have been reported 826. Levels of immunoglobulin expression are usually undetectable or 324 Mature B-cell neoplasms low. Postulated normal counterpart Post-germinal centre B cell with plasma blastic differentiation Genetic profile Immunoglobulin genes are clonally re arranged and hypermutated, indicating a B-cell derivation 2565,4234. They have complex karyotypes with numerous abnormalities, including trisomy 12, trisomy 7, and ab normalities of 1q21-25 1271. Prognosis and predictive factors the clinical outlook is extremely un favourable, and median survival is < 6 months. Constitutional symptoms include fever, night sweats, fatigue, weight loss, and respiratory symptoms 440. In addition to lymphadenopathy, patients may have hepatosplenomegaly and a skin rash 556. Laboratory find ings include anaemia, thrombocytope nia, hypoalbuminaemia, hypergammaglobulinaemia, and elevated C-reactive protein 556. The diagnosis requires exclusion of in fectious, neoplastic, and autoimmune diseases that may have similar clinical presentations. In this syndrome, the hypercytokinaemia may be driven by inflammatory disease or inflammatory gene mutations, autoantibodies, ectopic cytokine secretion, as seen in paraneo tres, with prominent mantle zones that may intrude into the germinal centres and completely efface them. Follicles may show onion skinning or widened concen tric rings of mantle zone lymphocytes, and prominent penetrating venules typi cal of Castleman disease. Among these mantle zone cells and adjacent interfollicular regions, there are variable num bers of medium-sized to large plasma blastic cells with amphophilic cytoplasm and vesicular, often eccentrically placed nuclei containing one or two prominent nucleoli. The blasts may be single in the intrafollicular and perifollicular areas, or may form small clusters or aggregates. Sheets of mature plasma cells expand the interfollicular region, including cells with cytoplasmic inclusions (Russell bod ies) and crystalline forms. As the dis ease progresses, the plasmablasts may coalesce to form clusters 1064,1404A. Prognosis and predictive factors Prognosis has been poor, related to the lymphoid proliferation and underlying immune disorder. The large plasmab lastic cells have vesicular, often eccentri cally placed nuclei containing one or two prominent nucleoli and amphophilic cy toplasm. The plasmablasts show either kappa or lambda light chain restriction but are polyclonal or oligoclonal. The lymphoid proliferation is characterized by medium-sized to large lymphoid cells resembling plasmablasts that involve or replace germinal centres. In some nodes, there may be atrophic fol licles resembling those seen in multicen tric Castleman disease. Prognosis and predictive factors In most cases, there is a favourable re sponse to chemotherapy or radiation 1047. The median age of the adult patients is 30 years, but there is also an incidence peak in elderly patients 2590. Recent data have provided new insight into how these two human pathogens interact to cause the disease, supporting the emerging con cepts of polymicrobial disease patho genesis 688,2692,2937,3285,3368. Localization Extranodal sites are most often involved, with some variation among the epide miological variants. The distal ileum, caecum, omentum, gonads, kidneys, long bones, thyroid, salivary glands, and breasts are frequently involved. Bone marrow in volvement may be present, but may not be associated with leukaemic expression 503,2912. In one case, Giemsa (A) and H&E (B) staining highlights uniform tumour cells with multiple small nucleoli and finely dispersed chromatin. In another case, Giemsa (C) and H&E (D) staining highlights greater nuclear irregularity. Breast involvement, often bilateral and massive, has been associated with onset during puberty, pregnancy, or lactation. Clinical features Patients often present with bulky disease and high tumour burden due to the short doubling time of the tumour. Specific clinical manifestations at presentation may vary according to the epidemiological subtype and the site of involvement. A revised international paediatric non-Hodgkin lymphoma stag ing system has been recently proposed 3417. Upon initiation of therapy, a tumour lysis syndrome can occur due to rapid tumour cell death. Its high and immediate chemosensitivity easily leads to an acute tu mour lysis syndrome. Macroscopy Involved organs are replaced by masses with a fish-flesh appearance, often associ ated with haemorrhage and necrosis. Even when nodal involvement is not present, uninvolved lymph nodes may be surrounded by tumour. The tumour cells are medium sized and show a diffuse monotonous pattern of growth. The cells appear to be cohesive but often exhibit squared-off borders of retracted cytoplasm in forma lin-fixed material. The nuclei are round, with finely clumped chromatin, and con tain multiple basophilic medium-sized, paracentrally located nucleoli. The cyto plasm is deeply basophilic and usually contains lipid vacuoles, which are better seen in imprint preparations or fine-nee dle aspiration cytology. The tumour has an extremely high proliferation rate, with many mitotic figures, as well as a high rate of spontaneous cell death (apopto sis). A so-called starry sky pattern is usu ally present, which is due to the presence of numerous tingible body macrophages. Some cases have a florid granulomatous reaction that may cause difficulties in the recognition of the tumour. These cases typically present with limited stage dis ease and have an especially good prog nosis 1549,1666. In other cases, par ticularly in adults with immunodeficiency, the tumour cells exhibit plasmacytoid differentiation, with eccentric basophilic cytoplasm and often a single central nucleolus 3396. The proliferation rate is very high, with nearly 100% of the cells positive for Ki-67. At least some of these cases constitute the new provisional entity Burkitt-like lymphoma with 11q aberration. Instead, they have a chromosome 11q alteration character ized by proximal gains and telomeric losses: specifically, interstitial gains including a minimal region of gain in 11q23. They also have a certain degree of cytological pleomorphism, occasionally a follicular pattern, and frequently a nodal presentation 3490,4454. Less com monly, they have a blastoid appearance, morphologically mimicking lymphoblas tic lymphoma or the blastoid variant of mantle cell lymphoma. This scheme is intended to help pathologists classify many of the aggressive B-cell lymphomas, using the morphology seen on an H&E-stained slide as the starting point. These cases are best considered to be a Burkitt-like lymphoma with 11q aberration.

For instance anxiety symptoms for days buy discount lexapro 10 mg on line, a person who is brought up with a severely healthanxious parent might be repeatedly encouraged to undergo extensive medical evaluations. This might give rise to dysfunctional assumptions about being particularly weak and physically vulnerable, or perhaps a strong conviction that physical sensations always require an explanation. Studies have 348 Erik Hedman and Erland Axelsson confirmed that health anxiety is associated with such dysfunctional health and illness related beliefs. As expected, healthanxious persons are also more likely than others to attribute common somatic symptoms. This is the case also in comparison with persons suffering from anxiety disorders (Neng & Weck, 2013), and when other symptom domains are controlled for (Marcus & Church, 2003). To summarize, both dysfunctional assumptions and an interpretive bias are characteristics of severe health anxiety. Processes that Maintain Severe Health Anxiety Many common reactions to health anxiety triggers, paradoxically, have the potential to maintain severe health anxiety over time. In some cases, this may lead to a selfperpetuating vicious circle, where cognitive, behavioral, and physiological processes strengthen each other. An immediate consequence of reacting to something with fear or anxiety is that these emotional states themselves involve a broad set of physiological processes, such as increased heart rate, hyperventilation, increased muscular tension, and altered blood flow (Sharpe & Bass, 1992). Longterm stress is also associated with particular physical symptoms, such as fatigue, cognitive weariness, sleep disturbances, and gastrointestinal complications (Shirom, Melamed, Toker, Berliner, & Shapira, 2005). High levels of health anxiety might thus lead to several forms of physiological changes, bringing about even more fear, leading to even more pronounced bodily symptoms, and so on. In the case of newly discovered physical sensations, healthanxious persons often continuously monitor their bodies in order to see whether symptoms subside or not. For persons with severe health anxiety, solely reducing the general degree of selffocused attention can therefore be enough to produce therapeutic effects (Papageorgiou & Wells, 1998). Over and above changes in attention, severe health anxiety is associated with a plethora of characteristic behaviors. For example, health anxious individuals search the Internet for medical information (Fergus, 2013) and seek healthcare more than others (Martin & Jacobi, 2006; Noyes et al. Just like such rituals, many illness behaviors are negatively reinforced, meaning that they are a response to an aversive stimulus (an anxiety provoking trigger) and persist because they are successful in neutralizing this stimulus (or alleviating anxiety). For example, a person with severe health anxiety may be concerned about a new symptom (aversive stimulus) and therefore searches the Internet for information (behavior) until he/she stumbles on information indicating that the symptom is benign and that there is no reason to worry (no threat, leading to reduced anxiety). As in this example, excessive illness behaviors can often be seen as a way of dealing with uncertainties. Severe Health Anxiety in the Somatic Symptom and Related Disorders 349 Even though the avoidance of health anxiety triggers. Historically, most theorists have emphasized that this process should be seen as an effect of failing to expose to aversive stimuli. There are newer conceptualizations of this process, which are arguably more in line with current basic science. Other mechanisms that have been proposed as responsible for the detrimental effects of excessive illness behavior (Warwick, 1989) include the following. These behaviors may sometimes themselves bring about new triggers for health anxiety. For example, sudden (supposedly beneficial) dietary changes may cause stomach discomfort, and patients with a fear of skin cancer may repeatedly pinch and scratch their rashes, thereby exacerbating the inflammation. These behaviors may serve as constant reminders, keeping patients continually focused on their anxietyprovoking and negative thoughts. Even though the idea that illness behaviors serve to reduce anxiety-and thereby maintain severe health anxiety-is widespread, few studies have investigated this relationship empirically. Salkovskis and Warwick (1986) described two cases where patients with severe health anxiety were given repeated medical reassurance by their physician. This led to substantial short term decreases in health anxiety and the self rated need for additional reassurance. Though, as expected, within roughly 24 hours this was followed by a relapse of health anxiety and a renewed need for reassurance. As these patients refrained from further reassurance seeking, their symptom measures gradually decreased within a few days or weeks. Lucock, Morley, White, and Peake (1997) replicated this pattern of large shortterm reductions of anxiety followed by a rebound of symptoms in a naturalistic setting with 17 patients with high levels of health anxiety undergoing gastroscopy. Abramowitz and Moore (2007) exposed 27 patients with severe health anxiety to individually tailored health anxiety triggers. The researchers investigated the effect of illness behaviors by randomizing participants to two conditions where half of the participants were encouraged to engage in illness behaviors and the other half were instructed to refrain from the use of such anxietyreducing strategies. The patients who performed some sort of illness behavior experienced a substantial shortterm decrease in health anxiety and in the urge to perform additional safety behaviors, whereas the patients who did not act on their urge reported a slower reduction of symptom levels, which nevertheless equaled those of the other group within one hour. Both this study and the one by Salkovskis and Warwick (1986) demonstrated a very strong association between fluctuations in health anxiety and the urge to engage in illness behavior. Taken together, these studies indicate that: (1) increases in health anxiety are likely to lead to illness behavior; (2) illness behavior often serves to reduce health anxiety; and (3) this anxiety reduction usually is shortlived in persons with severe health anxiety. Moreover, it has also been shown that one can develop higher levels of health anxiety simply by engaging in excessive illness behavior, such as frequent reassurance seeking and checking of 350 Erik Hedman and Erland Axelsson bodily functions (Olatunji, Etzel, Tomarken, Ciesielski, & Deacon, 2011). This, together with treatment studies where the main instruction to stop performing illness behaviors led to lower health anxiety (Visser & Bouman, 2001; Weck, Neng, Richtberg, Jakob, & Stangier, 2014), further strengthens the hypothesis that illness behaviors maintain severe health anxiety. To summarize, the strength of the cognitive behavioral model of severe health anxiety lies in its account of maintaining factors. These seem to interact within a balanced system, whereby changes in one maintaining factor are typically followed by corresponding changes in other domains. There is especially strong evidence that negatively reinforced illness behaviors maintain severe health anxiety. At least one randomized controlled trial has shown that psychoeducation based on a cognitive behavioral model can be effective as a stand alone treatment-without individually tailored behavior change exercises-for severe health anxiety (Buwalda, Bouman, & van Duijn, 2007). There are, however, multicomponent treatments in which psychoeducation is merely one intervention out of several. In these treatments psychoeducation largely serves the purpose of paving the way for later interventions, such as behavioral experiments or exposure. Without psychoeducation, the main components of these treatments would likely be experienced as out of context, painful, and unsympathetic, which would probably have a negative effect on treatment adherence. Cognitive Restructuring Techniques Empirically Supported Treatment Components Since around 1990 there has been a rapid increase in randomized trials showing that cognitive behavior therapy can yield large reductions of health anxiety and improvement of secondary symptoms of depression (Olatunji et al. In this section we present an overview of empirically supported components in the treatment of severe health anxiety, namely psychoeducation, cognitive restructuring techniques, exposure and response prevention, mindfulness training, and acceptancebased strategies. Psychoeducation In treatments for severe health anxiety, psychoeducation typically involves explaining how affected persons tend to overestimate the probability of medical disease, and that there are a plethora of sources including the fight/flight response-all unrelated to serious disease-that may give rise to bodily sensations. Consequently, the hallmark of cognitive therapy is that it entails components aiming to change these faulty beliefs. While cognitive therapy earlier emphasized the role of verbal cognitive restructuring, that is, using logical reasoning to bring about change in automatic health anxietyrelevant thoughts, it has become increasingly common to mainly use behavioral experiments to achieve this end. The purpose of behavioral experiments is to investigate the validity of automatic thoughts by testing them empirically. Another example would be to test the thought that intensive exercise would lead to acute stroke by quickly running up a steep staircase. The experiment should be conducted in a structured fashion whereby the patient is asked to specify the Severe Health Anxiety in the Somatic Symptom and Related Disorders 351 feared catastrophic outcome in advance, before designing a behavioral experiment in collaboration with the therapist. Although this intervention is similar to classical exposure, the rationale differs in one important aspect: where the former is seen as a means to new safety learning through a gradual decrease in the conditioned anxiety response, behavioral experiments are seen as a way of testing the validity of automatic thoughts. As anxiety reduction is not important per se (unless the experiment is designed to test some aspect of anxiety), it is perfectly fine that it be high or low at any phase of the experiment. What really matters is that enough information is collected so that the accuracy of the automatic thought can be tested. It is therefore also vital that the patient is taught not to use anxiety levels as an indicator of whether or not an experiment is successful, but instead stays focused on whether the outcome of the experiment supports or falsifies the automatic thought. Exposure and Response Prevention Exposure can be described as confronting stimuli that are unrealistically associated with danger, and response prevention as blocking the escape response that is triggered by the exposure (Roth, Foa, & Franklin, 2003).

Common findings at presentation include fatigue anxiety symptoms in young adults cheap lexapro 20 mg free shipping, malaise, weight loss, night sweats, and anaemia, and about 50% of patients have palpable spleno megaly 822,1662,1809,3534. However, bone marrow aspiration is es sential to ensure sufficient material for a complete karyotype and for morpho logical evaluation to confirm the phase of disease. Blasts usually account for < 5% of the marrow cells; 10% suggests advanced disease 817. Mega karyocytes may be normal or slightly decreased in number, but 4050% of cases exhibit moderate to marked megakaryocytic proliferation 495,3976,3982. A Peripheral blood smear showing leukocytosis and neutrophilic cells at various stages of maturation; basophilia is prominent; no dysplasia is present. B Bone marrow biopsy showing marked hypercellularity due to granulocytic proliferation. These features are mirrored in marrow biopsy sections, in which a layer of immature granulo cytes (510 cells in thickness) is common around the bone trabeculae, in contrast to the normal thickness of 23 cells 853. A Bone marrow biopsy specimen shows areas of cellular depletion and prominence of small megakaryocytes. The swirling appearance of the cells is caused by an increase in underlying reticulin fibres. Moderate to marked reticulin fibrosis, which correlates with increased numbers of megakaryocytes and may be associ ated with an enlarged spleen, has been reported in 3040% of biopsies at diag nosis 490,495,1329,3982. Death occurs due to bleeding or infectious complications, as normal haematopoiesis is increasingly disrupted by the malignant cells. How ever, their utility may be increased by the consideration of additional responsedefined parameters 1535. Clusters of small megakaryocytes (including true micro megakaryocytes similar to those seen in myelodysplastic syndromes) may be Table 2. In bone marrow biopsy specimens, sheets of blasts that occupy focal but substantial areas of the bone marrow. Expression of one or more myeloidrelated antigens by the blasts is common in both B- and T-cell-derived blast trans formations 2015,4261. A recent study showed a higher frequency of unusual blast types and immunophenotypes. Flow cytometry is the preferred technique for phenotypic analysis in order to detect mixed pheno types, but immunohistochemical stains can also be applied if a marrow aspirate cannot be obtained and there are insuf ficient numbers of blasts in the blood. The remaining cases have either variant translocations that involve a third or even a fourth chromo some in addition to chromosomes 9 and 22, or a cryptic translocation of 9q34. The site of the breakpoint in chromo some 22 may influence the phenotype of the disease 2619. Patients with this fusion may demonstrate promi nent neutrophilic maturation and/or con spicuous thrombocytosis 2619,3048. The mutations shown in green have been reported in < 2% of clinical resistance cases. The downstream chain of reactions is then halted because, with its tyrosines in the unphosphorylated form, the substrate does not assume the necessary conformation to ensure association with its effector. Today, few patients die from leukaemia, and the overall survival is similar to that of the non-leukaemic population 207,1602. Definition Chronic neutrophilic leukaemia is a rare myeloproliferative neoplasm character ized by sustained peripheral blood neu trophilia, bone marrow hypercellularity due to neutrophilic granulocyte prolifera tion, and hepatosplenomegaly. The diagnosis requires exclusion of reactive neutrophilia and other myeloproliferative and myelodysplastic/myeloproliferative neoplasms (Table 2. Acute myeloid leukaemia has supervened in 3 cases of a chronic neutrophilic leukaemialike condition as sociated with a plasma cell neoplasm, but all 3 patients had been exposed to leukaemogenic drugs before the emer gence of acute myeloid leukaemia 995, 2294,4079. The association of a con dition resembling chronic neutrophilic leukaemia with other neoplasms is also likely to reflect a leukaemoid reaction. Localization the peripheral blood and bone marrow are always involved, and the spleen and liver usually show leukaemic infiltrates. Clinical features the most constant clinical feature re ported is splenomegaly, which may be symptomatic. A history of bleeding from mucocutaneous surfaces or from the gastrointestinal tract is re ported in 2530% of cases 1588,4501. Microscopy the peripheral blood shows neutrophilia, with a white blood cell count 25 x 109/L. The neutrophils are usually segmented, but there may also be a substantial in crease in band forms. In almost all cases, neutrophil precursors (promyelocytes, myelocytes, and metamyelocytes) ac count for < 5% of the white blood cells, but occasionally they may account for as much as 10% 515,1094,1096A,1588, 4441,4501. Myeloblasts are almost Epidemiology the true incidence of chronic neutro philic leukaemia is unknown; > 200 cas es have been reported, but only about 150 of these meet the current diagnostic criteria 231. In one study of 660 cases of chronic leukaemias of myeloid origin, not a single case of chronic neutrophilic leukaemia was observed 3642. Chronic neutrophilic leukaemia generally affects older adults, but has also been reported rarely in adolescents and young adults 1588,4441,4501. In 116 patients whose age and sex were reported, the median age at presentation was 66 years and the maletofemale ratio was 1. In about a quarter of reported cases of chronic neutrophilic leukaemia or an apparently similar con dition, the neutrophilia was associated with an underlying neoplasm, most often multiple myeloma or monoclonal gammopathy of undetermined significance. The majority of such cases constitute a neutrophilic leukaemoid reaction result ing from synthesis of granulocyte colonystimulating factor by neoplastic plasma cells. A very small number of patients ap pear to have had both a plasma cell neo plasm and true chronic neutrophilic leu Chronic neutrophilic leukaemia 37 never observed in the blood. The neu trophils often show toxic granulation and Dohle bodies, but they may also appear normal. However, it should be noted that toxic granulation and Dohle bodies ap pear to be more consistently present in plasma cellassociated leukaemoid re actions than in chronic neutrophilic leu kaemia 231). Myeloblasts and promyelocytes are not increased in percentage at the time of diagnosis, but the proportion of myelocytes and mature neutrophils is increased. Megakaryocytes may be cytologically normal or there may be increased smaller forms. Given the frequency of neutrophilic leu kaemoid reaction in association with multiple myeloma and monoclonal gammopathy of undetermined significance, the bone marrow should be examined for evidence of a plasma cell neoplasm 231,595,995,3764,3765. If plasma cell abnormalities are present, clonality of the neutrophil lineage should be dem onstrated by cytogenetic or molecular techniques before a diagnosis of chronic neutrophilic leukaemia is made. In the spleen, the infiltrate is mainly confined to the red pulp; in the liver, in filtration may affect the sinusoids, portal areas or both 4441,4501. Cytochemistry the neutrophil alkaline phosphatase score is usually elevated, but is occasion ally normal or even low 231. However, because the score is also usually elevat ed in neutrophilic leukaemoid reactions, this is not a diagnostically useful test. Cell of origin A haematopoietic stem cell, which may have limited lineage potential 1259,4417 Genetic profile Cytogenetic studies are normal in nearly 90% of cases. In the remaining cases, reported clonal karyotypic abnormali ties include gains of chromosomes 8, 9, and 21; del(7q); del(20q) (the most fre quently observed abnormality); del(11q); del(12p); nullisomy 17; a complex karyo type; and several non-recurrent translo cations 735,846,970,1094,1259,2553, 3475,4417. Complete cytogenetic remission with imatinib was reported in a patient with chronic neutrophilic leukae mia and t(15;19)(q13;p13. Prognosis and predictive factors Although generally considered a slowly progressive disorder, chronic neutro philic leukaemia is associated with vari able survival, ranging from 6 months to > 20 years. The neutrophilia is usually progressive, and anaemia and thrombo cytopenia may follow. The development of myelodysplastic features may signal a transformation of the disease to acute myeloid leukaemia 1588,4501. Transfor mation has been reported following cyto toxic therapy, but also in its absence. The diagnosis requires integration of clinical, laboratory, and bone marrow histological features, as outlined in Table 2. Bone marrow biopsy showing age-adjusted hypercellularity with trilineage growth (panmyelosis), including prominent erythroid, granulocytic, and megakaryocytic proliferation with pleomorphic, mature megakaryocytes (differences in size) 3. Ionizing radiation and occupational expo sure to toxins have been suggested as pos sible causes in some cases 526,3606. Localization the blood and bone marrow are the major sites of involvement, but the spleen and liver are also affected and are the major sites of extramedullary haematopoiesis in later stages. Most reports indicate a slight male predomi nance, with a male-to-female ratio of 12:1 2500,3209.

Regardless of what the substance is, a careful functional analysis of how the two behaviors influence each other is necessary. In such cases, clinically significant 228 Sarah Fischer, Kendra Davis, and Lauren Breithaupt perfectionism is defined as the "overdependence of selfevaluation on the determined pursuit of selfimposed personally demanding standards of performance. This means that individuals with clinical levels of perfectionism and an eating disorder are not only constantly evaluating themselves on their weight, shape, and appearance, but also their progress toward very high standards of achievement in other domains, such as school, career, or family. Additionally, such individuals disregard indicators of progress or achievement other than their own personal metric. As may be imagined, it is impossible to achieve such high standards of performance in all these areas. Thus, the distress associated with failure inevitably ensues, and this helps to maintain the cycle of attempts to control weight and shape via restraint. Appraisal and Applications How Do Mechanisms of Psychopathology Interfere with Treatment Outcome Weight and shape concerns, and thus restraint, are of course extremely entrenched behaviors in an individual with an eating disorder. However, a large segment of the population also endorses body dissatisfaction and dieting attempts (Cash & Henry, 1995; Davison & McCabe, 2005; StriegelMoore et al. Therapists themselves are not immune to internalization of the thin ideal and the desire to lose weight. Thus, it is not only challenging to tackle the severity and entrenchment of these thoughts in the individual being treated. That the client will walk out of the session into a cultural environment in which weight and shape concerns are pervasive also makes it difficult to alter these mechanisms. However, it is fairly clear from the literature that the focus on these behavioral changes early on in treatment is actually helpful for symptom reduction and therapeutic alliance. Additionally, therapeutic alliance may be strengthened as a result of reduction of binge eating (Raykos et al. In fact, increased weight negatively influences earning potential, hiring decisions, and perceived attractiveness (Agerstrom & Rooth, 2011; Baum & Ford, 2004; Richmond, Austin, Walls, & Subramanian, 2012). Thus, both the therapist and the client may encounter difficulty when restructuring thoughts about the importance of weight and shape. It is important for the therapist to keep the focus of cognitive restructuring Bulimia Nervosa 229 on the importance of weight and shape for self worth, to acknowledge that it may not be a distortion to believe that weight and shape impact how one is evaluated in our society, and to maintain insight into his or her own weight bias or stigma. However, abstinence rates for binge and purge symptoms are not very high, especially when compared to success rates for cognitive behavioral treatments for other disorders, such as anxiety disorders. Fairburn and colleagues argue that their original cognitive behavioral formulation was too narrow in scope and that an expanded transdiagnostic model, which includes elements of perfectionism, mood intolerance, and interpersonal distress, should be used to guide treatment formulation (Cooper & Fairburn, 2011).

This approach incorporates interventions targeting psychological accept ance, mindful awareness of experience, values clarification, as well as various intervention strategies derived from traditional behavior therapy. Collectively, these treatment compo nents are designed to enhance psychological flexibility, or the capacity to engage in mean ingful patterns of behavior while contacting the present moment and accepting whatever thoughts and feelings may occur. Such an approach could reduce the burden of implementing a range of different treatment packages for vari ous problems, improve treatment of comorbid and complex presentations, and clarify the key pathological and therapeutic mechanisms that may be most important to human suffering and its amelioration. For example, what is the evidence that psychological inflexi bility is a core pathological process and what are the boundary conditions to which it no longer applies What factors might interfere with treatment for specific populations and how can these be addressed Although a broadly applicable, multicomponent treatment model can be useful, it also presents difficulties in determining exactly when and how to apply it in any given case. What Is the Evidence that Psychological Inflexibility Is a Core Pathological Process The subprocess that has received the most research and clinical attention to date is experi ential avoidance, which refers to rigid patterns of behavior seeking to avoid, escape, reduce, or otherwise alter unwanted thoughts and feelings. The most notable issue is that the vast majority of research has relied on selfreport measures. It would behoove researchers and practitioners to be appropriately skeptical of the meaning of evidence gathered from such measures given that they are highly subject to demand characteristics, are limited by level of introspection and awareness, and fail to objec tively and directly measure the pathological phenomenon of interest. Recently measures have been developed to more precisely assess these subdomains such as cognitive fusion. In sum, it is not entirely clear if psychological inflexibility is the common pathological pro cess or if other third variables might account for some of these effects. What Problems Does Psychological Inflexibility Apply to and Where Does It Not Apply The breadth of research suggests that psycho logical inflexibility applies to the myriad psy chological problems that have been studied to date, though in the context of some notable limitations in the available research. Thus far, we are not aware of any research that has systematically identified boundary conditions in which psychological inflexibility does not appear to be functionally related to a problem. For example, social skill deficits can also contribute to psychological problems such as problematic interpersonal behavior in depression. Although reducing psychological barriers to effective action may be important in such cases, ultimately such actions will not be effective if one does not have the necessary behavioral repertoires to interact well with oth ers. This raises the question of whether some psychological problems, or at least some pre senting cases, are merely problems of skill defi cits and have little or nothing to do with psychological inflexibility. In other words, if individuals were taught the requisite behavioral skills, could they effectively use them without encountering psychological barriers The avail able research literature does not provide clear answers to this question. Implications of Psychological Inflexibility Research for Clinical Decision Making of existing research. In the area of psychological inflexibility, more systematic research is especially needed using measures of specific inflexibility subprocesses, with more refined methodologies. An impor tant next step would be to clarify how and for whom psychological inflexibility leads to , exac erbates, and maintains psychological problems in a way that would better guide clinical deci sion making. Second, although psycho logical inflexibility seems related to a broad range of problems, this is not to say that every presentation is necessarily due to inflexibility or that inflexibility is the only relevant treat ment target, particularly given the limitations Empirically Supported Treatment Components Clinical decision making includes knowing what components of treatment to use, and in what sequence and ratios, to provide quality care for a given client most efficiently and effec tively. For example, with a depressed client, should the clinician start with targeting values or acceptance Are there components of treatment that would be most reasonable to leave out, particularly in cases where treatment length must be limited Little empirical data exists on these and related questions, which is not surprising given the number of iterations to be tested and the methodological challenges presented. Such research can be made more efficient with a theory that specifies which mechanisms are targeted by specific components and how such components interact, which can guide more critical tests (Herbert, Gaudiano, & Forman, 2013). Similarly, cognitive defusion is central to values, as clients need to learn how to step back from what they think they "should" value in order to identify more personally meaningful and empowering values. In this section we will review the evidence for each of these components and their interactions, with an eye toward gaps in the literature and available suggestions to guide clinical decision making. Doing so can inform more efficient treatment protocols, as well as prioritizing components when delivering treatment in timelimited settings. At the simplest level this could be examined by assessing whether each component has an active impact on psychological outcomes. A recent metaanalysis examined this question across 66 laboratorybased studies, and found significant positive effects for the acceptance, defusion, values, and present moment compo nents when tested in isolation (Levin, Hildebrandt, Lillis, & Hayes, 2012). Committed action was excluded from this metaanalysis (since it is connected to wellresearched behav ioral methods), but no studies were found at the time on self as context. However, these results should be interpreted with caution given that most samples were nonclinical in nature and there are notable methodological limitations often found in such research. Thus, many studies end up targeting a combination of com ponents when the intervention scripts are reviewed by other researchers (Levin et al. Similarly, selecting comparison condi tions in such research is quite complex and depends on the questions being asked. As a result, many of the active effects of components have been found relative to inert comparison conditions. Determining whether components in isola tion have some impact on outcomes is a rela tively low bar and does not address what components are necessary to have an impact within a clinical population using psychother apy. This answer requires further research using much more intensive methods such as disman tling designs. One laboratorybased study found that adding the values compo nents to an acceptance component in a brief intervention increased persistence in a painful cold pressor task compared to the acceptance component alone (BranstetterRost, Cushing, & Douleh, 2009). While these results are preliminary and not focused on clinical populations, they provide some initial support to the idea that adding at least the values component may improve outcomes. Some clues may also be found in survey research, though of course followup research using more experimental designs is necessary. For example, there is some survey research sug gesting that present moment awareness alone is unlikely to be effective and needs to interact with other components. Research on mind fulness subscales that specifically assess the propensity to attend to experiences in the present moment have found that this factor actually correlates with greater problems in some cases. Subsequent research has found that such awareness subscales interact with other facets of mindfulness. For example, those who are more aware but also reactive tend to have greater substance use problems, while those who are aware and nonreactive tend to have fewer problems (EisenlohrMoul, Walsh, Charnigo, Lynam, & Baer, 2012). Although significantly limited by the use of selfreport measures and a nonintervention context, this research suggests that training present moment awareness only without teaching someone how to respond flexibly to the experi ences noticed may be ineffective and even iatrogenic. This notion is consistent with mind fulness approaches, which emphasize present moment awareness in a context that is explicitly defused and accepting. Despite focusing on this more limited subset of components, behavioral activation is clearly an effective treat ment for depression (Dimidjian et al. However, the degree to which each component is needed to treat a given case, and what components a clinician would provide under which condi tions, are unclear. Further research using dis mantling designs is needed to determine whether there is incremental value to including both mindfulness and values/behavior change components in a larger treatment, particularly given the success of other treatments that focus primarily on just mindfulness or values/behav ior change. Clinical decision making highlights not only the need to know which components are needed for treating a case, but also how best to sequence these components and when to provide each. Again, the research is lacking here, with only one multiple baseline study to date that examined the effect of treatment sequencing (Flessner, Busch, Heideman, & Woods, 2008). This raises the question of whether both components are needed for all clients, and sug gests that the sequence of these components had little impact on efficacy. The most traditional of these sequences begins by targeting experiential avoidance. The rationale for this sequence is, first, to reduce the potential that clients will continue to approach therapy within the framework of experiential avoidance. This is done in part to reduce the potential for clients to focus on values that are themselves rigid and not linked to meaningful patterns of living. Lastly, committed action is then used to pull together all of the components and skills in therapy to build larger patterns of behavior linked to values, which, arguably, may be most effectively achieved after such skills and values have been learned and clarified. The rationale for this approach is, first, to build motivation to engage in therapy and to clarify the focus of therapy on meaning ful patterns of behavior.

Approximately 75% to 90% of individuals presenting with an animal anxiety buzzfeed cheap 20mg lexapro amex, natural environment, or situational phobia are female. Additionally, animaltype phobias have been found to be the most common specific phobia in women, while situational phobias. While the literature suggests that females suffer from phobias at greater rates than males, it is important to consider the effect of cultural expectations and the tendency of males to underreport symptomology (Muris, Schmidt, & Merckelbach, 1999). These findings collec tively suggest that phobias are one of the most common psychological disorders (if not the most common), making it imperative that mental health professionals understand empirically sup ported components and treatments designed to combat this chronic and impairing fear (Van Houtem et al. Comorbidity Specific phobias are highly comorbid, with rates of additional diagnoses ranging from 60% to 75% (American Psychiatric Association, 2013; Kim et al. The Origins of Specific Phobias Tripartite Model of Fear Fear is often associated with specific, physiologi cal responses that people later consciously label as fear (Lang, 1979). Fear is further marked by behaviors such as avoidance; avoidance maintains phobias by pre venting the extinction of fear responses (Lang, 1979). Once individuals develop specific pho bias, they either endure the feared stimuli with great distress or avoid the stimuli entirely. Avoidance prevents individuals from having positive or neutral experiences with the object of their fear, allowing for negative experiences or misconceptions to persist (Davis et al. These behaviors maintain specific phobias through negative reinforcement, as individuals are rewarded with the removal of the aversive or feared stimuli through avoidance. Lastly, fear is experienced cognitively, as individuals access memories, thoughts, and cognitions associated with the stimuli they experience (Lang, 1979). Often, this experience involves activation of catastrophic cognitions- thoughts about the worst outcomes of the feared stimuli, environment, or situation. According to the tripartite model, physiological responses, behaviors, and cognitions all interact to produce the fear response. These components may occur together with the same intensity or in varied intensities. Recent research is attempting to understand the charac teristic differences between individuals with distinct patterns in physiological, behavioral, and cognitive experiences of fear (Davis, Hurley, & Ollendick, 2003; Ollendick, Allen, Benoit, & Cowart, 2011). Heritability of Specific Phobias the genetic components of fear and phobias have been documented in the literature for dec ades, though largely based on animal research. The resulting offspring for the following three generations exhibited significant limitations in functioning, including social instability and elevated anxiety. A recent metaanalysis captures variances in the heritability of phobias (Van Houtem et al. Overall variance esti mates of strictly additive genetic contribution have ranged from. While psychological dif ficulties are understood to run in families, many people do not realize that the physiologi cal responses of psychopathology are also highly heritable. Additionally, the degree to which fears are acquired by both learning paradigms and biological components may be determined by other risk factors (Marks, 2002), and it has been suggested that it is the additive effects of multiple experiences that lead to a phobia in these instances. Direct Experience As previously discussed, much of the literature has concluded that specific phobias (and most anxiety disorders) run in families, partly as a result of genetics. Theories of fear acquisition initially postulated that fear comes from a learned response, such as a classi cal conditioning paradigm. This explanation was popularized from the Little Albert study, in which a stimulus was linked to a frightening stimulus, conditioning a fear response to occur with each presentation of the previously neutral stimulus (Watson & Rayner, 1920). This may be, in part, explained by biological preparedness models which theorize that some stimuli. However, many believe that nonassociative frameworks Classical conditioning, or the formation of fears and phobias from direct experience with stim uli, has been heavily researched. One recent metaanalysis compared components of fear conditioning in participants with anxiety disor ders to participants without psychological dis orders. During the learning phase, results suggested an increased fear response to conditioned neutral stimuli in participants with anxiety disorders compared to controls. The authors hypothesized that the difficulty of inhibiting fear and easier attribution of stimuli to fear may be characteristic of people with anx iety disorders. During the extinction phase, participants had increased discrimination com pared to controls, suggesting that people with anxiety disorders are slower to extinguish fear responses (Duits et al. Taken together, it is less likely that individuals are "hardwired" for a particular phobia or fear, but rather they inherit a tendency to more easily associate cer tain stimuli with fear (Mineka & Zinbarg, 2006). As a result, the issue may be how much direct experience with a feared stimulus is necessary to condition a phobic response (cf. Modeling Furthermore, the learned experience of fear can also extend to the family environment. For example, parents with phobias may model fear responses to their children at a young age (Bandura, 1977). The study also found that over half (54%) of the children in the study had at least one parent suf fering from a mood or psychological disorder, 46% of the children had a parent with an anxiety disorder, and 32% had a parent with a specific phobia. The prevalence of parental psychopa thology further illustrates the applicability of social learning theory to specific phobias. Negative Information Similarly, a specific phobia can be learned simply through the transmission of negative informa tion. Parents or caregivers may directly instruct a child to avoid a specific object or situation, or may provide information to the child that is overly negative. For example, a parent might tell a child to be careful around dogs because they often bite and hurt people. A recent study exam ined the consequences of negative information by presenting a group of children with informa tion about a novel animal, nicknamed "the beast" (Muris, Bodden, Merckelbach, Ollendick, & King, 2003). Children either received positive or negative information about this imaginary crea ture, and researchers measured the level of their fear at three time points (before receiving any information about the beast, after receiv ing information, and at oneweek followup). Unsurprisingly, children who received negative information about the imaginary creature had higher levels of fear than children who received positive information at the second time point. Notably, however, this level of fear was main tained through the followup period, suggesting that even small amounts of negative information can create and maintain fear in the absence of experience. Furthermore, this crafted fear gener alized to other contexts and animals, as children who were given negative information about the doglike beast also became more fearful of dogs and similar creatures. Field (2006) investigated negative information by monitoring attentional biases in children. He gave children negative information about novel animals before using a probe task to see how this negative information affected their attention. Findings demonstrated that negative, frightening information about a stimulus contributes to attentional biases toward that stimulus. Field and Lawson (2008) also dem onstrated that the type of verbal information (positive or negative) impacted the acquisition speed of outcomes of situations involving ani mals. For example, children who received no information about the animals took significantly more trials to accurately estimate the probabili ties of set outcomes. At the same time, children given negative information learned the contin gencies much quicker; these children also overes timated the number of negative outcomes when outcomes were consistent with the negative information received earlier. This research dem onstrates how learned information might lead to cognitive biases that contribute to fear. Mechanisms of Change in Specific Phobias Cognitions: Information Processing and Biases Anxious beliefs, predictions, and expectations about the feared stimulus are important factors in both creating and maintaining specific pho bias. Notably, the same study found that attentional bias decreased with longer exposures to photographs of spiders, even in highfear individuals; this suggests that exposure alone is effective in treating phobia (as measured by reductions in attentional bias). However, the literature is mixed on the evidence for attentional bias; a recent study examined attentional hypervigilance in individ uals with high and low injection fear and found that individuals with greater levels of fear did not orient to injection images more often than other emotional images (Armstrong, Hemminger, & Olatunji, 2013).

A third lesson from this research is that there may be some core mechanisms underlying change regardless of the type of treatment being provided anxiety 40 year old woman order lexapro 5 mg without a prescription. Each is complex in its own right; managing multiple challenges simultane ously is even more difficult, but it also can be seen as intriguing and interesting. This final section addresses some of these challenges and ideas for how to manage them. Automatic Processing and Conditioned Craving Some clients experience strong cravings for alcohol, particularly early in treatment. Clients also experience cravings that they may view as inexplicable-their experience is that they "come out of nowhere" or "I just wanted to drink. First, it is helpful to educate clients about the nature of cravings: that they tend to be time limited, that they are elicited by cues previously associated with drinking, and that there is a bio logical or physiological component to them. Second, it is helpful for clients to monitor their cravings and the situations that elicit cravings. Therapists can assist clients to develop coping skills for these situations along with awareness of situational cues. Recent research suggests that active cognitive coping techniques (Szasz, Szentagotai, & Hofmann, 2012) may be more effective than acceptancefocused strategies. For some clients, cue exposure with response prevention (Budney, Brown, & Stanger, 2013) Alcohol Use Disorders: Treatment and Mechanisms of Change 243 may decrease reactivity to alcohol cues. Finally, it may be helpful to schedule sessions more frequently early in treatment, and to end each session with a discussion of upcoming situa tions that might elicit cravings and to plan for specific coping strategies to handle them. Some research from cogni tive psychology suggests two promising tech niques to improve inhibitory control-working memory training and the use of contingency management approaches (Koffamus, Jarmolowicz, Mueller, & Bickel, 2013). Working memory training typically is accomplished through com puter programs and may be less accessible to the typical clinician in clinical practice. Contingency management procedures, which provide specific rewards for specific behaviors. These procedures may be imple mented through contingency contracts with family members as well as through contingen cies applied directly by the clinician. Affect Regulation and Coping Skills have few other coping skills to manage these emotions. As with coping with craving, psychoe ducation may be a helpful first step with such clients-the clinician may help them recognize that they have less experience with a range of emotions, and less experience in managing emotion. Additionally, clients may be experien cing a protracted withdrawal, in which ongoing neuroadaptation to being without alcohol may also accentuate emotions, particularly anxiety and depression. Specific interventions targeting mood management have been less successful than coping skills training. Clients who continue to show substantial diffi culties with affect regulation after a period of sobriety (typically at least a month) should be evaluated for other possible disorders. If they appear to have a specific disorder, additional psycholo gical or pharmacological therapy for the disorder would be appropriate. Their predominant approach to coping with negative affect may have been to drink, and they may As discussed above, competing factors move clients toward and away from changing their drinking. Clients may have a strong desire to change their drinking because they recognize the adverse consequences of drinking for their health, relationships, and work; they may also be strongly motivated to change because of external forces. However, the reinforcing properties of alcohol, social reinforcement for drinking, conditioned responses to drinking related cues, low selfefficacy relating to change, lack of effective coping skills, and com plicating psychological and social problems all draw the client toward drinking. Several inter ventions help to address ambivalence, includ ing feedback, the use of decisional balance exercises, and the use of motivational inter viewing techniques. Each of these factors is challenging for clinicians to manage in the course of treat ment. Research on active therapist ingredients in effective treatment has focused largely on therapeutic interventions to impact coping skills and the reward salience, and suggests that effective therapists will provide structure and direction to the therapy, and use a number of techniques to enhance motivation and decrease the reward salience of alcohol.

Loss of genetic material most frequently involves 6q21 (in 52% of cases) anxiety cures generic 20 mg lexapro visa, 6p21 (in 37%), 8q12. Older patient age (> 65 years) is a major negative prognos tic factor and is associated with reduced survival as well as an increased risk of neurotoxicity related to therapy 14,2084. High-dose methotrexate-based poly chemotherapy is currently the treatment of choice 2084. The inclusion of wholebrain irradiation may improve outcome, but carries the risk of neurotoxicity re sulting in severe cognitive, motor, and autonomic dysfunction, particularly in el derly patients 14. Most protocols report a median progression-free survival of about 12 months and an overall survival of approximately 3 years. With improvement of outcome, some sporadic systemic relapses have been observed; these can involve any organ, but relatively frequently involve the testis and breast 1828. It typically occurs in elderly patients, in particular women, with a male-to-female ratio of 1:34. Localization these lymphomas preferentially affect the lower legs, but 1015% of cases arise at other sites 2062,3623,4499. Prognosis and predictive factors Earlier studies reported a 5-year survival rate of approximately 50% 1421,1422, 4189. Most cases oc cur in patients over age 50, with a peak in the eighth decade 3661. However, cases also occur in younger patients sporadically, with a second smaller peak in the third decade 2867. Alterations in the im mune microenvironment may play a role at any patient age 668,2867. In young patients (aged < 45 years), the disease is predominantly nodal, with only about 10% of cases show ing extranodal involvement 2867,4087. Clinical features the clinical features at presentation are variable 1017,1663,2867,3018,3019. The neoplastic com ponent most often consists of a variable number of large transformed cells/immunoblasts and Hodgkin/Reed-Sternberglike cells. There is a variable component of reactive elements, including small lymphocytes, plasma cells, histiocytes, and epithelioid cells. The rich back ground of small lymphocytes and histio cytes may resemble T-cell/histiocyte-rich large B-cell lymphoma, also referred to as the polymorphic pattern in some stud ies 2867,4087. Large areas of geographical necrosis and angioinvasion are other characteristic find ings, but they are not always present. The disease is aggressive, with a median survival of about 2 years in elderly pa tients, even when treated with rituximab immunochemotherapy 1017,3019,3527, 3820, but younger patients appear to have an excellent prognosis, with long term complete remission in > 80% 2867, 4087. In elderly patients, B symptoms and age > 70 years appear to be adverse prognostic factors 3019; patients with neither, one, or both of these factors have median overall survival times of 56, 25, and 9 months, respectively. The lesions often arise in lo cations subjected to local tissue damage or inflammation, such as in the intestine in patients with inflammatory bowel dis ease 2132. Regional isolated lymphadenopathy is rarely seen, but there is no evidence of systemic lymphadenopathy, hepatosplenomegaly, or bone marrow involvement. Clinical features the symptoms are related to the ulcerat ed lesion, whether in the oral cavity, skin, or intestine. The disease has a mild male predominance and a median patient age > 70 years 1018. Microscopy the mucosal or cutaneous surface is ulcerated, sometimes with pseudoepitheliomatous hyperplasia of the adja cent intact epithelium. Beneath the ulcer, there is a dense polymorphic infiltrate with a variable number of plasma cells, histiocytes, and eosinophils, as well as a substantial number of large transformed cells, resembling either atypical immuno blasts or Hodgkin/Reed-Sternberg-like cells. Angioinvasion and necrosis can be present in addition to surface ulcera tion 1017,1018. The lymphocytes in the background are abundant, many with angulated and medium-sized nuclei. However, the diagnosis of classic Hodg kin lymphoma in the skin or in mucosa should be rendered only with extreme caution. The deepest margin of the le sion usually contains a band-like infiltrate of mature lymphocytes. Prognosis and predictive factors Case reports and series suggest a be nign natural history, with nearly all re ported cases responding to reduction of immunosuppressive therapy. In patients in whom immunosuppression cannot be reversed, responses to rituximab, lo cal radiation, and chemotherapy have been observed. However, rare cases of relapses or progression to more widespread disease 2721 have been reported. Patient age at diagnosis ranges from the fifth to eighth decade of life (median: 6570 years) 2818,2827. The male-tofemale ratio is 12:1 versus nearly equal in chronic pyothorax, suggesting that males are more susceptible to this type of lym phoma than are females 1797. Radiologi- cal examination reveals a tumour mass in the pleura (in 80% of cases), pleura and lung (in 10%), or lung near the pleura (in 7%). Patients who develop lymphoma in the bone, joint, periarticular soft tissue, or skin usually present with pain or mass le sion. Most cases show centroblastic or immunoblastic morphology, with round nuclei and large single or multiple nucleoli. Cytogenetic studies show complex karyotypes with numerous numerical and structural ab normalities 3874. For patients achieving com plete remission with chemotherapy and/ or radiotherapy, the 5-year survival rate is 50% 2818. Complete tumour resection (pleuropneumonectomy with or without resection of adjacent involved tissues) has also been reported to give good re sults 2809. Poor performance status; high serum levels of lactate dehydroge nase, alanine transaminase (also called glutamic-pyruvic transaminase), or urea; and high clinical stage are unfavourable prognostic factors 119,2827. Fibrin-associated diffuse large B-cell lymphoma An unusual form of diffuse large B-cell lymphoma associated with chronic in flammation is not mass-forming and does not directly produce symptoms, but is discovered incidentally on histological examination of surgical pathology speci mens excised for various pathologies other than lymphoma. The specimens typically contain fibrinous materials, such as in the walls of pseudocysts (having been reported in splenic false cyst, renal pseudocyst, adrenal pseudocyst, paratesticular pseudocyst, and pseudocyst in ovarian teratoma), hydrocoele, lesions or materials located in the cardiovascular system (having been reported in cardiac myxoma, cardiac prosthesis, cardiac fi brin thrombus, and synthetic tube graft), wear debris (associated with metallic implants), and chronic subdural haematoma 36,418,1479,1907,2388,2663,4114, 4115. A Clusters of large lymphoma cells are visible within the fibrinous material that overlies an atrial myxoma. The lymphoma cells show irregular nuclear foldings, coarse chromatin, distinct nucleoli, and ampho philic cytoplasm. Chronic inflammatory cell infiltration in the background or vicinity is usually not prominent. The immunophenotypic features are similar to those of pyothorax-associated lymphoma, with expression of B-cell lineage markers and an activated B-cell phenotype. Unlike in pyothorax-associated lympho ma, the clinical outcome is highly favour able, even with surgical excision alone. However, one report raised the possibility of progression to an infiltrative tumour; an incidental diffuse large B-cell lymphoma associated with chronic inflammation arising in a chronic subdural haematoma was accompanied by brain parenchymal infiltration 1907. Diffuse large B-cell lymphoma associated with chronic inflammation 311 Lymphomatoid granulomatosis Pittaluga S. The lesion has a spectrum of histological grade and clinical aggressiveness, which is related to the proportion of large B cells. Clinical features Patients frequently present with signs and symptoms related to the respiratory tract, such as cough, dyspnoea, and chest pain. Constitutional symptoms are also common, including fever, malaise, weight loss, neurological symptoms, arthralgias, myalgias, and gastrointestinal symptoms. The lesions are most often bilateral in distribution, in volving the mid- and lower lung fields. Nodular le sions are found in the kidneys and brain, usually associated with central necrosis 1966,3726. Cutaneous plaques or a maculopapular rash are less common cutaneous mani festations 309,1823,1965,2604. Lymphocytes predominate and are admixed with plasma cells, immu noblasts, and histiocytes. The background small lymphocytes may show some atypia or irregularity, but do not appear overtly neoplastic. It usually presents in adulthood, but may be seen in chil dren with immunodeficiency disorders. It affects males more often than females, with a male-to-female ratio of 2:1 1965, 3726.

The most common comorbid disorders include another substance use disorder anxiety symptoms muscle twitches order 20 mg lexapro overnight delivery, depression, and anxiety disorders. The most common comorbid personality disorders are antisocial personality disorder and borderline personality disorder (Rosenthal, 2013). Automatic Processing of AlcoholRelated Cues Alcohol consumption typically occurs in the context of a set of external and interoceptive cues; over time these cues elicit a conditioned craving response. If a person does not drink in response to these cues, the desire for alcohol intensifies and is experienced as craving. Craving is experienced as a subjective state, but responses in the autonomic nervous system and neurocognitive changes can also be observed. Over time, consistent pairing of specific cues with alcohol consumption may also lead to a conditioned withdrawal state as the body "prepares" itself for alcohol (see Bickel, Mueller, & Jarmolowicz, 2013). The first is an overactive impulsive decisionmaking system, which is focused on immediate cues and immediate responses. The second is a relatively underactive cognitive control system, based in the prefrontal cortex, which is involved in planning, inhibiting of specific responses, and selfaware processing and decision making (see Morgenstern, Naqvi, Debellis, & Breiter, 2013). Deficits in Affect Regulation and Other Coping Skills Reinforcement of alcohol consumption occurs through basic operant principles. Both animal and human research has shown that individuals will selfadminister alcohol, and reward path ways in the brain show increased activity when a person is exposed to alcohol and alcohol cues (Bickel et al. Taken together, these studies have dem onstrated that alcohol is a positive reinforcer (similar to food or water). These social networks pro vide cues for drinking as well as positive conse quences for heavier drinking, thus providing another type of reinforcement for drinking. Emotion regulation includes a number of facets, such as awareness of emotions, the capacity to either amplify or attenuate emotional responses (Axelrod, Perepletchikova, Holtzman, & Sinha, 2011), and the ability to access a range of strate gies to cope with emotions (Blonigen, Timko, & Moos, 2013). Reviews of largescale treatment outcome studies have found that, in the year after treat ment, about 25% clients will maintain sustained abstinence, that about 10% will use alcohol in moderation and without problems, and that, on average, clients will reduce the amount they drink by about 87%. Alcoholrelated problems also decrease after treatment, by about 60% (Miller, Walters, & Bennett, 2001). Although they are not a focus of this chapter, there also are efficacious pharma cotherapies, including naltrexone, extended release naltrexone, and acamprosate, with other pharmacologic agents under study (Wilcox & Bogenschutz, 2013). Thus, the sequencing of treatment is dependent on the specific approach being used by the treating clinician. Mechanisms of Behavior Change Since the beginning of the twentyfirst century, alcohol research has moved from a focus on developing efficacious treatment to a focus on understanding the mechanisms by which success ful change occurs. Active ingredients are what the therapist does in the therapy session, as well as the programmatic and physical environ ment in which the therapy is delivered. These client behaviors should affect the mechanisms of behavior change, the "process or series of events through which one variable leads to or causes a change in another variable" (Nock, 2007, p. The relationships between variables may differ based on specific client characteristics, or moderators, which help to "identify on whom or under what conditions treatment have different effects" (Kraemer, Wilson, Fairburn, & Agras, 2002, p. Active ingredients, client behaviors/statistical mediators, and mechanisms of change may be common to most therapies; they may be distinctive (present in some therapies) or specific (present in one type of therapy but not others). Common Mechanisms of Change Active Ingredients As is true of treatment for many psychological disorders, there are several active ingredients in Table 16. These include the development of a positive therapeutic alliance and the provision of empathy and supportiveness to the client (Meier, Barrowclough, & Donmall, 2005). As with directiveness, providing therapy that is structured and goaldirected also leads to more positive outcomes, but is also moderated by client reactance-more reactive clients respond better to therapy that is less structured (Karno & Longabaugh, 2005). Finally, a number of studies have found that conducting a structured assessment of client drinking and the negative consequences of the drinking, and then provi ding the client with feedback on the results of the assessment lead to better outcomes (Clifford & Davis, 2012; Worden & McCrady, 2013). Client Behaviors or Mediators of Change Three types of client behaviors or mediators of change seem to predict positive outcomes across a range of treatments. Clients who initiate abstinence early in treatment and sustain abstinence during treatment do better than clients who continue to drink, even intermittently, during treatment (Maisto, Clifford, Stout, & Davis, 2008). Mechanisms of Change be thought of as motivation or readiness to change, a commitment to abstinence, or a reap praisal of the consequences of continuing to drink. Closely connected with selfefficacy is an increase in substancespecific coping skills, including cog nitive, affective, and behavioral coping which may, in turn, result in less negative affect and less impulsive and/or more planful behavior. Thus, changes in craving may reflect changes in the automatic processing of alcohol cues; increased goal direction and/or motivation to change may reflect changes in reward processing, and changes in the social network may mark changes in perceived poten tial reinforcement for drinking; selfefficacy and coping skills relate to both coping skills and adaptive decision making. Mechanisms of Change Client verbal behaviors in the treatment session are fairly robust predictors of positive treatment outcomes. In alcohol treatment, clients often talk about reasons to change their drinking as well as reasons to continue to drink. Mechanisms of Change No mechanisms of change have been identified that are distinctive to a small number of treat ment interventions. Appraisal and Applications Implications for Treatment Planning and Sequencing In general, very little research has identified active ingredients, client behaviors, or mecha nisms of change that are unique to a single treatment. Active Ingredients the only active therapy ingredient related to outcomes that is specific to one treatment approach is the application of a contingent sys tem of rewards, in contingency management based treatments (reviewed in Longabaugh, Magill, Morgenstern, & Huebner, 2013). A first, clear lesson from this research is that, as with all clients, therapists should pay attention to the therapeutic relationship, express empathy, work to develop a therapeutic bond, and be supportive to the client. McCrady this difficult, either because they reactive nega tively to what the client has done while actively drinking. Angry and oppositional clients call for a less structured approach than more compliant clients. Thus, the therapist should be listening carefully for client comments about changing versus continuing to drink. When rea sons to sustain drinking seem to be prominent, the therapist should be concerned and should focus on supporting and paying attention to change talk, regardless of the therapeutic orientation.

Effectiveness of a feedbackbased brief intervention to reduce alcohol use in community substance use disorders treatment. Although varying criteria for insomnia have been used in different research studies, between 30% and 50% of the population has reported insomnia symptoms (Ohayon, 2002). When more rigorous diagnostic criteria are used to assess for insomnia, including daytime impairment. Psychiatric disorders have been found in as many as 40% of patients with clinical levels of insomnia, and the prevalence of insomnia in some psychiatric disorders (major depression and anxiety disorders) has been reported as being as high as 80% for some specific psychiatric diagnoses. The sleep disturbance must create problems for the patient and occur for at least three nights per week over at least three months (between one and three months is considered episodic, with more than three months thought to be persistent). Obtaining sufficient sleep must be difficult, despite the patient allowing for an adequate amount of time to obtain sleep. The insomnia is not better explained by or occurs exclusively in the context of another sleep disorder and it must not be attributable to medication or drugs. Finally, any coexisting mental disorders and conditions do not adequately explain the complaint of the insomnia (American Psychiatric Association, 2013). Although there are no actual cutoffs written in the definition to help determine what is considered an abnormal length of time awake, many insomnia specialists tend to use the convention of 30/3/30 (Lichstein, Durrence, Taylor, Bush, & Riedel, 2003). This guidepost suggests that disturbed sleep would be classified as such when the time spent awake at sleep onset or in the middle of the night is greater than 30 minutes and occurs at least three times a week for 30 or more days. Where one patient with insomnia may have three nights a week where it takes three hours to fall asleep, another patient may report a sleep latency of 60 minutes nearly every night. In addition to the 30/3/30 guide and reported significant distress or impairment in daily functioning, the insomnia cannot occur exclusively during another sleep disorder, mental disorder, or general medical condition. It must also not be due to the effects of a substance (pharmacotherapy or substance abuse). Cognitive Behavior Therapy for Insomnia 249 Insomnia as a Comorbid Condition Arguably one of the biggest advances in insomnia conceptualization comes from recent research that suggests that insomnia is not simply a symptom of another medical or psychiatric illness. When patients are given a diagnosis of insomnia "secondary" to another issue, the main focus of treatment is on the primary cause, with insomnia getting neither the attention nor the treatment it actually deserves.
