The authors described the effects of vitamin D deficiency on the mother and newborn based on serum concentrations of vitamin D antibiotics lyme generic ofloxacin 400 mg. The maternal effects of severe deficiency (defined as <10 ng/mL) were an increased risk of preeclampsia, calcium malabsorption, bone loss, poor weight gain, myopathy, and higher parathyroid hormone levels, whereas those in the newborn included small for gestational age, hypocalcemia with possible seizures, heart failure, enamel defects, large fontanelle, congenital rickets, and rickets of infancy if breastfed. For serum concentrations (11­32 ng/mL) considered insufficient, the maternal effects were bone loss and subclinical myopathy, whereas those in the newborn were hypocalcemia, decreased bone mineral activity, and rickets if breastfed. There were no maternal or newborn adverse effects if the vitamin D concentration was 32­100 ng/mL, but levels >100 ng/mL could cause maternal hypercalcemia and increased urine calcium loss, and hypercalcemia in the newborn (39). A direct relationship exists between maternal serum levels of vitamin D and the concentration in breast milk (41). Chronic maternal ingestion of large doses may lead to greater than normal vitamin D activity in the milk and resulting hypercalcemia in the infant (42). In the lactating woman who was not receiving supplements, controversy exists about whether her milk contained sufficient vitamin D to protect the infant from vitamin deficiency. Several studies had supported the need for infant supplementation during breastfeeding (12,40,43­45). Other investigators had concluded that supplementation is not necessary if maternal vitamin D stores are adequate (28,46­48). However, recent evidence suggests that vitamin D supplementation of lactating women with much higher doses is necessary to increase the nutritional vitamin D status of the mother and her breastfeeding infant (36,37). This is especially true for darkly pigmented individuals and those having limited exposure to ultraviolet light. Although the required dose has not been adequately studied, doses identical to those described for pregnancy (see Fetal Risk Summary section) have been suggested (37). A study published in 1977 measured high levels of a vitamin D metabolite in the aqueous phase of milk (49). Although two other studies supported these findings, the conclusions were in direct opposition to previous measurements and have been vigorously disputed (50,51). The argument that human milk is low in vitamin D is supported by clinical reports of vitamin D deficiency-induced rickets and decreased bone mineralization in breastfed infants (44,45,52­54). Moreover, one investigation measured the vitamin D activity of human milk and failed to find any evidence for significant activity of water-soluble vitamin D metabolites (55). A second committee of the American Academy of Pediatrics classifies vitamin D as compatible with breastfeeding, but recommends monitoring the serum calcium levels of the infant if the mother is receiving pharmacologic doses (57).

Vitamin D-deficiency rickets in two breastfed infants who were not receiving vitamin D supplementation. One study did find a lower birth weight in infants of women taking high doses of vitamin E during pregnancy, but the reduced weight was not thought to be clinically significant and may have been due to other factors. However, in wellnourished women, adequate vitamin E is consumed in the diet and supplementation is not required. Vitamin E concentrations in mothers at term are approximately 4­5 times that of the newborn (2­8). Maternal blood vitamin E level usually ranges between 9 and 19 mcg/mL with corresponding newborn levels varying from 2 to 6 mcg/mL (2­9). Supplementation of the mother with 15­30 mg/day had no effect on either maternal or newborn vitamin E concentrations at term (4). Use of 600 mg/day in the last 2 months of pregnancy produced about a 50% rise in maternal serum vitamin E (+8 mcg/mL) but a much smaller increase in the cord blood (+1 mcg/mL) (7). Although placental transfer is by passive diffusion, passage of vitamin E to the fetus is dependent on plasma lipid concentrations (8­10). At term, cord blood is low in -lipoproteins, the major carriers of vitamin E, in comparison with maternal blood; as a consequence, it is able to transport less of the vitamin (8). Because vitamin E is transported in the plasma by these lipids, recent investigations have focused on the ratio of vitamin E (in milligrams) to total lipids (in grams) rather than on blood vitamin E concentrations alone (9). The reason given by the women for taking high doses was that large amounts of vitamins were part of a healthy lifestyle, but none took large doses of vitamins A and D. The mean duration was 6 months and 44 (54%) took a high dose throughout gestation. There were no differences in the outcomes between the groups in terms of live births, spontaneous abortions, elective abortions, stillbirths, gestational age at delivery, prematurity, and malformations. Because only two infants had a birth weight <2500 g, the difference was thought to have a questionable clinical significance. Moreover, vigorous exercise was thought to be part of a "healthy lifestyle" and it might also reduce birth weight (13). Vitamin E deficiency is relatively uncommon in pregnancy, occurring in less than 10% of all patients (3,4,14). No maternal or fetal complications from deficiency or excess of the vitamin have been identified. Early studies used vitamin E in conjunction with other therapy in attempts to prevent abortion and premature labor, but no effect of the vitamin therapy was demonstrated (17,18). Premature infants born with low vitamin E stores may develop hemolytic anemia, edema, reticulocytosis, and thrombocytosis if not given adequate vitamin E in the first months following birth (16,19,20). In two studies, supplementation of mothers with 500­600 mg of vitamin E during the last 1­2 months of pregnancy did not produce values significantly different from controls in the erythrocyte hemolysis test with hydrogen peroxide, a test used to determine adequate levels of vitamin E (7,16). Milk obtained from preterm mothers (gestational age 27­33 weeks) was significantly higher (8. The authors concluded that milk from preterm mothers plus multivitamin supplements would provide adequate levels of vitamin E for very low-birth-weight infants (<1500 g and appropriate for gestational age). Japanese researchers examined the pattern of vitamin E analogs (-, -, -, and -tocopherols) in plasma and red blood cells from breastfed and bottle-fed infants (23). Several differences were noted, but the significance of these findings to human health is unknown. Vitamin E applied for 6 days to the nipples of breastfeeding women resulted in a significant rise in infant serum levels of the vitamin (24). Although no adverse effects were observed, the authors cautioned that the long-term effects were unknown.

Larger tumors show heterogeneous attenuation because of the presence of hemorrhage and necrosis, but they do not contain fat. Extensive base of attachment to adjacent structures and absence of clear tissue plane from the aorta is important to convey for operative planning. Botolin S et al: Aseptic loosening of pedicle screw as a result of metal wear debris in a pediatric patient. A fracture at the base of left pedicle has resulted from aberrant stresses produced by failed hardware. The bone loss is greater near the tip, indicating that the screw is toggling back and forth. There is thinning of the lateral cortex of the right iliac wing, which predisposes the patient to bone fracture. It also helps to identify the key physiologic impairments that need to be addressed. Besides history, examination and pulse oximetry data, further information can be obtained from chest radiograph, laboratory tests to assess for infections, and blood gases (capillary or arterial, if feasible). For those with trauma, further primary and secondary assessments should be performed to evaluate for other sites of injuries. For patients with impending or overt signs of respiratory failure, the first priority should be to secure their airway and then continue to evaluate them for underlying cause on an ongoing basis. Monitoring of vital signs (temperature, heart rate, respiratory rate and blood pressure), oxyhemoglobin saturation by pulse oximetry and perfusion (capillary refill time) should be repeated at frequent intervals while the assessment is being continued. Further investigations for assessment of the cause of respiratory failure can be done on the basis of the clinical syndrome at presentation and presence of any underlying chronic (lung or heart) disorders. Scoring system Several clinical scoring systems have been devised for the objective assessment of respiratory distress in infants and children. These scoring systems are especially helpful in serial assessment of the same patient over time as the score can yield data for determining the trends and overall response to therapy for each patient. These have been used as outcome measures in randomized controlled clinical trials for assessing response to specific therapies, but their usefulness may be limited by interobserver variability in scoring. Additional findings related to chronic respiratory disorders, such as digital clubbing, presence of polycythemia or poor nutritional status can provide additional clues. In some situations, such as cardiac failure or circulatory shock, respiratory failure can develop secondarily due to inadequate tissue perfusion causing metabolic acidosis, which can lead to tachypnea and hyperventilation. There are buffers (bicarbonate, phosphate and proteins) that try to maintain the pH as close to normal as possible. In children with chronic lung disorders, the build up of carbon dioxide can occur slowly as their lung disease progresses, resulting in chronic respiratory acidosis. The main components include assessment of acid-base status by evaluating the pH as the first step to define acidosis or alkalosis. Finally, assessing the degree of compensation for the primary disturbance acid-base disturbance completes the interpretation. Metabolic disturbances on the other hand, are defined by exclusion of any respiratory related acid-base disturbances. However, this may be different in the setting of chronic respiratory acidosis where the extent of drop in pH may be much lower than seen in conditions associated with acute respiratory acidosis. The third step involves the assessment of the compensatory response, which can be either complete or incomplete. If the pH is restored to the normal range, then full compensation exists but for cases where pH remains below normal, then the compensation is partial. A stepwise approach for interpreting the arterial blood gas results is shown in Flow chart 1. The kidneys compensate for respiratory acidosis and metabolic acidosis of nonrenal origin by excreting fixed acids and retaining the filtered bicarbonate. For respiratory alkalosis or metabolic alkalosis of nonrenal origin, the kidneys compensate by decreasing the hydrogen ion excretion and reducing the retention of filtered bicarbonate. In patients with chronic respiratory failure, the control of ventilation tends to shift from the respiratory center in the brainstem to the peripheral chemoreceptors located in the carotid and aortic bodies. In fact, ventilation is driven in this situation by the hypoxemia that stimulates the peripheral chemoreceptors. The compensatory changes that take place in the setting of chronic respiratory acidosis and alkalosis are different from those occurring in the setting of acute respiratory acidosis or alkalosis (as shown in Table 3). Besides the increase in plasma bicarbonate, the renal response also includes an increase in chloride excretion, causing hypochloremia. This loss of chloride balances the increase in plasma bicarbonate levels, thereby maintaining a normal plasma anion gap. This can significantly affect their effort tolerance, which can be objectively measured and tracked with a six-minute walk test. These cases may also be further evaluated by electrocardiogram and echocardiography for the assessment of cardiac function. Assessment of pulmonary function by spirometry can be performed in children older than 6 years of age to monitor progression of chronic lung disease and to assess for improvement in response to therapies. Please refer to Chapter 7 regarding airway management, rapid sequence intubation and resuscitation. These can be used with oxygen tanks in a clinic or walled supply in the hospital setting for patients that need lower level of support for maintaining adequate oxygenation. They should be of adequate size, extending from the bridge of the nose to the tip of the chin, with a snug fit and put no pressure on the eyes. The nonrebreathing types of facemasks have an oxygen reservoir attached to them, which allows patients to get pure oxygen held in the reservoir and minimizes mixing with room air. This may be considered prior to the use of traditional invasive ventilatory support and can help avoid intubation and its related complications in several acute reversible as well as chronic conditions with acute decompensation. In general, noninvasive ventilation devices have evolved from use of negative pressure ventilators in patients with poliomyelitis in early 20th century to its current use for both short-term and longterm support in hospital as well as home settings. Positive Pressure Ventilation A majority of patients with respiratory failure will require positive pressure ventilation, especially if they are not suitable candidates for or have failed noninvasive ventilatory support. For delivery of positive pressure support, most patients require endotracheal intubation but in those with chronic respiratory failure, placement of a tracheostomy tube may be necessary to provide a secure, longer-term access to the airway. There are numerous ventilator devices, modes and approaches and these are discussed in detail in Chapter 8. Intensive Care and Emergencies Symptoms of hypoventilation and impending respiratory failure Underlying disorders Reversible acute conditions-pneumonia, acute asthma exacerbation, etc. A wide variety of oronasal interfaces (nasal prongs, nasal masks, oronasal masks, total face mask), circuits (single limb or double limb for inhalation and exhalation) and devices with a variety of modes are now available. High Frequency Oscillatory Ventilation High frequency oscillatory ventilation allows recruitment of lung units with higher mean airway pressures while limiting ventilatorinduced lung injury by using extremely small tidal volumes and lower peak inspiratory pressures. This allows lungs to be ventilated on the steeper and more compliant portion of the pressure volume curve. Gas exchange occurs with diffusion and pendelluft and patients have to be deeply sedated and paralyzed while on this mode of ventilation. Negative Pressure Ventilation Negative pressure ventilation creates a pressure gradient between the mouth and alveoli by lowering the body surface pressure below atmospheric pressure. The negative intrathoracic pressures also enhance venous return as opposed to traditional positive pressure ventilators that reduce venous return. This may be an option for patients who require long-term respiratory support but want to avoid the use of a tracheostomy or facial masks used with other noninvasive ventilation devices. This is done by diverting blood flow away from the lungs into an extracorporeal (outside the body) device that can oxygenate the blood and then pump it back into the systemic circulation. This can be done until the lungs recover from the primary insult or disease process that caused respiratory failure in the first place. Both approaches require the placement of large cannulas in the major blood vessels to allow blood to be withdrawn and returned to the patient after oxygenation. Systemic anticoagulation is used to prevent clotting of the blood in the circuit but it increases the risk of bleeding as well. It also requires frequent monitoring to ensure the level of anticoagulation is maintained appropriately. Paying close attention to use of airway clearance techniques (postural drainage, huff cough or the use of mechanical insufflation-exsufflation device or CoughAssist) to prevent atelectasis and mucus plugging in patients with neuromuscular disorders can also help to minimize respiratory morbidity. Placement of tracheostomy for use of longterm positive pressure support may be considered for those with chronic respiratory failure with careful weaning of support as the underlying condition improves.

Analogous populations of mouse monocytes have been defined based on the level of the cell surface marker Ly6C antibiotics for acne from dermatologist order ofloxacin. Notably, in murine models of atherosclerosis, such as the apo E­ deficient mouse, exposure to a high-cholesterol diet over time results in expansion of the proinflammatory Ly-6Chigh monocyte pool. In terms of diabetes, Ly-6Chigh monocytosis is also associated with obesity-induced adipose tissue infiltration of Ly-6Chigh macrophages, which may contribute to the proinflammatory state associated with metabolic syndrome and diabetes. Direct connections among diabetic-associated vascular dysfunction, atherosclerosis, and monocyte-subsets in these animal models have not yet been made. The importance of this finding is unclear as it relates to atherosclerosis pathogenesis in diabetes but continues to be pursued. The role of specific monocyte subsets in diabetic macrovascular disease remains an active area of study. Indeed, an important relationship between fatty acid signaling and monocyte activation exists in diabetes. Notably, the presence of diabetes has been shown to increase peripheral blood monocyte count. Other drivers of inflammation and atherosclerosis relevant to diabetes are also under study. Lymphocyte differentiation has important effects on atherosclerotic plaque biology. Disruption of Th1 lineage reduces atherosclerosis in murine models of disease and has been generally associated with proatherosclerotic responses. In addition, smaller subsets of T cells including T regulatory cells (Tregs) and Th17 lymphocytes exert local control on plaque inflammation and plaque expansion. Recent data demonstrate that the expansion of visceral fat is associated with a loss of local Treg cells. This highlights emerging data connecting changes in inflammatory cells and cardiometabolic issues. Although cell biologic approaches and animal models have provided key scientific insights into atherogenesis, ongoing efforts are directed toward translating these findings to human disease. The identification of stable, circulating biomarkers of inflammation has allowed investigators to test prospectively how indices of inflammation relate to atherosclerosis disease burden and clinical events, including responses to current agents and therapies under development. It is interesting to note that these drugs were in clinical use before it was realized that these receptors were also expressed in vascular and immune cells. Important, pioglitazone did not seem to have higher risk of adverse events in this study. A necessary distinction must be maintained between the biologic target and the therapeutic agent(s). The experience with pioglitazone underscores the need for those trials to be carefully thought out, given that reversal of the primary and secondary endpoints in this trial, and a longer duration, may well have had a profound effect on the diabetes therapeutic landscape. Incretins (glucagon-like peptide-1 analogs), a new therapeutic modality for diabetes, also have direct effects on the vasculature. The intricacies of this picture are evident in attempts to deconvolute the nature of the vascular biology of diabetic atherosclerosis-the factors that drive the disorder, determine outcomes, and, it is hoped, offer openings for interrupting the natural history. The challenges in understanding the molecular basis of the intersection of diabetes and atherosclerosis are legion, given overlapping issues between these two diseases: very long subclinical phases, a frequency in the population that sets up multiple confounding variables, shared mechanistic underpinnings, and cellular players such as adipocytes and macrophages with many similar characteristics. All of these issues combine with clinical experience to frame a fundamental question in this field: To what extent is diabetic atherosclerosis unique and distinct from atherosclerosis, or is it simply the same disease accelerated in the context of hyperglycemia and other factors? It is amazing that, despite intense efforts by many groups using different approaches over many years, this question remains unresolved. Clearly the issues considered here are important in diabetic atherosclerosis independent of whether they are unique to diabetes or not. Diabetic dyslipidemia is a central part of the diabetic picture, with all the key components of the arterial wall and the inflammatory system altered by interaction with the altered lipid metabolism of diabetes. Endothelial dysfunction is an early part of the disease even before diabetes or cardiovascular complications become apparent.

In the treated group antibiotics for uti elderly cheap ofloxacin 400mg overnight delivery, 228 women were given B-complex vitamins plus vitamin C before or during the 1st trimester. Although suggestive of a positive effect, the difference between the two groups was not significant. In contrast, one author suggested that the vitamin A in the supplements caused a cleft palate in his patient (10). Thus, the published studies involving the role of multivitamins in the prevention of cleft lip and/or palate are inconclusive. No decisive benefit (or risk) of multivitamin supplementation has emerged from any of the studies. The differences between the case mothers and the controls were significant for red blood cell folate (p <0. Based on this experience, a multicenter study was launched to compare mothers receiving full supplements with control patients not receiving supplements (16­19). The supplemented group received a multivitamin­iron­calcium preparation from 28 days before conception to the date of the second missed menstrual period, which is after the time of neural tube closure. The daily vitamin supplement provided: Their findings, summarized in 1983, are shown below for the infants and fetuses who were examined (19): Although the numbers were suggestive of a protective effect offered by multivitamins, at least three other explanations were offered by the investigators (16): 1. Although multivitamin supplements were not studied, it was assumed that those patients who consumed adequate diets also consumed more vitamins from their food compared with those with poor diets. The above investigations have generated many discussions, criticisms, and defenses (24­57). The primary criticism centered on the fact that the groups were not randomly assigned but were self-selected for supplementation or no supplementation. A follow-up study, in response to some of these objections, was published in 1986 (58). In addition, none of the four factors would have predicted more than a 4% increase in the recurrence rate in nonsupplemented mothers compared with those supplemented. The results indicated that none of these factors contributed significantly to the differential risk between supplemented and nonsupplemented mothers, thus leading to the conclusion that the difference in recurrence rates was caused by the multivitamin (58). The case group involved either liveborn or stillborn infants with anencephaly or spina bifida born during the years 1968­1980 in the Atlanta area. Multivitamin usage and other factors were ascertained by interview 2­16 years after the pregnancies. This long time interval might have induced a recall problem into the study, even though the authors did take steps to minimize any potential bias (59). The odds ratios for whites, but not for other races, were statistically significant. In commenting on this study, one investigator speculated that if the lack of a statistical effect observed in black women was confirmed, it may be related to a different genetic makeup of the population (60). During the interval 1980­1984, 261 gastric bypass procedures were performed in Maine, but only 133 were in women under the age of 35. She became pregnant again 2 years later and eventually delivered a stillborn infant in the 3rd trimester. The infant had a midthoracic meningomyelocele, iniencephaly, absence of diaphragms, and hypoplastic lungs. Gastric bypass surgery is known to place recipients at risk for nutritional deficiencies, especially for iron, calcium, vitamin B12, and folate (61,63). In the third report, of a total of 908 women who underwent the procedure, 511 (56%) responded to a questionnaire (63). Moreover, the three mothers had not consumed vitamin supplements as prescribed by their physicians. Because of these findings, the authors recommended pregnancy counseling for any woman who has undergone this procedure and who then desires to become pregnant (63). In another brief reference, the final results of a British clinical trial were presented in 1989 (64). Mothers were requested to take the vitamin formulation described above for at least 4 weeks before conception and until they had missed two menstrual periods. The results of the study included three reporting intervals: 1977­1980, 1981­1984, and 1985­ 1987. The 148 fully supplemented mothers (those who took vitamins as prescribed or missed taking vitamins on only 1 day) had 150 infants or fetuses, only 1 (0. In contrast, 315 nonsupplemented mothers had 320 infants or fetuses among which there were 18 (5. However, others concluded that this study lead to a null result because: (a) the vitamin consumption history was obtained after delivery, (b) the history was obtained after the defect was identified, or (c) the study excluded those women taking vitamins after they knew they were pregnant (66). The study population was comprised of 22,715 women for whom complete information on vitamin consumption and pregnancy outcomes was available. Women were interviewed at the time of a maternal serum fetoprotein screen or an amniocentesis. For those using the preparation during the first 6 weeks of pregnancy, 10 cases occurred from a total of 10,713 women (prevalence 0. For mothers who used vitamins during the first 6 weeks that did not contain folic acid, the prevalence was 3 cases in 926, a ratio of 3. An investigation into a third class of anomalies, limb reduction defects, was opened by a report that multivitamins may have caused this malformation in an otherwise healthy boy (52). A retrospective analysis of Finnish records, however, failed to show any association between 1st trimester use of multivitamins and limb reduction defects (67).

Unusual limb reduction defect in infant born to mother taking periconceptional multivitamin supplement. Multivitamins and prevention of neural tube defects: a need for detailed counselling. The absence of a relation between the periconceptional use of vitamins and neural-tube defects. Lack of association between vitamin intake during early pregnancy and reduction limb defects. This effect also has been noted in rats treated with another triazole agent, fluconazole. In those studies, the anti-estrogen action was thought to be responsible for the observed cleft palate and bone abnormalities (see Fluconazole). Nevertheless, based only on the animal data, one review concluded that voriconazole should be avoided in pregnancy (1). Although there are currently no human data, the close relationship with fluconazole, a suspected teratogen in high doses, is reason enough to avoid voriconazole in the 1st trimester.

Glucose values are monitored hourly while the patient is on an insulin drip and every 15 minutes when serum glucose levels are 70 mg/dL or below treatment for sinus infection in horses generic ofloxacin 400 mg on line. However, in those patients with persistently elevated glucose (above 180 mg/dL) after cardiopulmonary bypass, a continuous insulin drip should be instituted. Oral agents are resumed when target glucose levels are maintained and the patient is tolerating a normal diet. Metformin should not be restarted until the patient is documented to have normal renal function. The best method to achieve consistent glycemic control in clinically stable patients with diabetes is with scheduled basal or bolus insulin therapy. This is accomplished best with subcutaneous insulin that combines long- or intermediate-acting insulin with rapid-acting insulin administered simultaneously with nutritional intake.

These may contribute to raised blood pressure, abnormal blood lipids, raised blood glucose, and overweight and obesity. The increasing frequencies of obesity and sedentary lifestyles-major risk factors for the development of type 2 diabetes, in both developed and developing countries-will further contribute to diabetes being a growing clinical and public health problem worldwide. The incidence rates of myocardial infarction during the 5 years of follow-up in this study in men and women with diabetes and without prior myocardial infarction were 7. Available data on patients with diabetes are heterogeneous, because diabetic patients with a long duration of the disease have a different cardiovascular risk than patients with shorter disease duration. In the ideal setting, information regarding the long-term risk of a patient with newly diagnosed diabetes mellitus for coronary artery disease and its complications would be desirable, but data on the long-term risk of cardiovascular events for patients with new onset of diabetes are scarce. In 2030 there will be approximately 23 million deaths caused by cardiovascular diseases. In theory, such an approach would be possible in countries where civil registration systems can be matched with, for example, prescription registries, allowing the identification of patients in whom glucose lowering treatment has been initiated. Patients with diabetes were older and more often had concomitant diseases as well as prior coronary interventions compared with those participants without diabetes Table 19-3). Ideally, they should be representative of the clinical population covered by the guideline recommendation. In a review about the importance of translating data from randomized trials and registries into clinical information, Brown and colleagues8 deplored that results of observational studies are often dismissed in favor of prospective randomized trials. Prospective observational studies provide an unprecedented opportunity to at least estimate the epidemiology of diseases and the varying use of management strategies, as well as their outcomes, in consecutive patients in clinical practice. Current smokers are patients self-identified as currently smoking tobacco, irrespective of duration of smoking history or number of packs per day. In a subset of 16,116 patients hospitalized from April 1999 to September 2001, 25. Franklin and colleagues10 reported that patients with diabetes were less likely to be treated according to guidelines and had an increased risk for heart failure, renal failure, cardiogenic shock, and death Table 19-6). The Euro Heart Survey on Diabetes and the Heart35 recruited 3488 patients to study the prevalence of abnormal glucose regulation in adult patients with coronary artery disease, of whom two thirds presented with unstable coronary artery disease. Although no separate analysis was provided to discriminate between patients with stable and unstable coronary artery disease, these data encourage the improved implementation of evidence-based guidelines to decrease adverse cardiovascular events, especially in patients with diabetes. The Global Registry of Acute Coronary Events, Arch Intern Med 164:1457-1463; 2004. The prevalence of diabetes will continue to grow worldwide, with about one-half of coronary artery disease patients with diabetes presently undiagnosed. This will be of clinical importance because both patients with known diabetes and those with newly diagnosed diabetes are less likely to receive evidencebased treatments and are more likely to develop cardiovascular adverse events. Of 8795 patients with available data of known diabetes or at least one of the reported glucose values, 2860 (32.

A decrease in pubertal growth has been observed virus x the movie buy ofloxacin once a day, especially in females with earlier menarche, suggesting genderdimorphic susceptibilities. The rates of preterm births have risen worldwide in recent years, mainly due to medically induced preterm delivery, and the global incidence stands at 11. The major immediate complications encountered in preterm newborns are difficult delivery room resuscitation, respiratory distress syndrome, apnea, hypotension, hypothermia, hypoglycemia, necrotizing enterocolitis, intracranial hemorrhage, feeding difficulties, and vulnerability to infections and iatrogenic complications. Late sequelae in preterm newborns include retinopathy of prematurity, bronchopulmonary dysplasia, periventricular leukomalacia, metabolic bone disease, anemia of prematurity, poor growth and neurodevelopmental impairments. Metabolic Risks Intrauterine growth restriction infants are at significantly increased risk of developing hypertension, dyslipidemia, obesity and type 2 diabetes during adulthood. Several hypotheses have been put forward to explain the association between low birthweight and increased metabolic risks. Barker and colleagues proposed the hypothesis of fetal programming to explain the developmental origins of adult diseases. The fetal cortisol hypothesis postulated that maternal nutrient restriction may act to reprogram the development of the pituitaryadrenal axis, resulting in excess glucocorticoid exposure and adverse health outcomes in later life. Another hypothesis was fetal insulin hypothesis which proposed that genetically determined insulin resistance results in impaired insulin-mediated growth in the fetus, as well as insulin resistance in adult life. Obesity is also potentiated by alterations in appetite regulation and increased adipogenesis. Leptin, a primary satiety factor which reduces food intake in a normal child, has been shown to be one of the factors influenced by fetal programming. Reduced numbers of nephrons are associated with elevations in arterial blood pressure and changes in postnatal renal function. Diabetes is associated with decreased beta cell number and function along with alterations in cellular insulin signaling. Preventing preterm births: analysis of trends and potential reductions with current interventions in 39 countries with very high human development index. Born too soon: accelerating actions for prevention and care of 15 million newborns born too soon. Postulated underlying mechanisms include delayed metabolic adaptation, 432 Chapter 13. Preterm babies develop significant calorie and protein deficit during first few weeks of life without adequate nutrition which subsequently becomes difficult to compensate and remains a major cause of postnatal growth retardation. Though the early aggressive nutrition policy has reduced the initial weight loss and birthweight regain earlier but it is still not optimal. In a growing preterm baby, extra protein is required to compensate for initial losses and weight gain during growth period. Only high calorie intake may match in utero growth rate but leads to more fat growth than lean body mass. The Newborn Infant Lipid Lipids are required not only as one of the major source of energy but also to provide essential components for cell membrane functions and bioactive eicosanoids. The initial weight loss is presumed to be predominantly extracellular fluid loss but the contribution by protein, glycogen and lipid losses are not known. In utero it is predominantly protein and glycogen while fat accretion occurs mainly during third trimester whereas ex utero major source of nutrients are fat and glucose and less protein, hence body composition differs in the fetus and the newborn infant. A minimum amount of glucose is required to maintain brain and other glucose dependent organs as well as to prevent protein by preventing gluconeogenesis. In addition postnatal sickness adds to catabolism and leads to higher need of calorie. The focus should be achieving an optimal lean mass rather than fat mass which happens with excess calorie and without adequate protein intake. Calcium and Phosphorus Calcium absorption depends on calcium and vitamin D intake and retention depends on absorbed phosphorus. Adequate calcium intake is required to ensure adequate bone mineralization in preterm infants. Phosphate absorption is quite efficient in those who are fed human milk or preterm formula but also depends on bioavailability of calcium and nitrogen retention. Disorders of Weight and Gestation Volume to Start and Rate of Advancement the ideal volume to start with and the rate of advancement are debatable. The rate of increase depends on weight, gestation, postnatal age, clinical status and tolerance of oral feeds. Table 3 provides a suggested approach for initiation and hike in stable preterm neonates while transiting from intravascular fluid to enteral feeds. Vitamin D Vitamin D is important for bone mineralization and neuromuscular function and also improves calcium absorption. Preterm babies are born with low vitamin D stores and quite often born to vitamin D deficient mothers. Rapid mineralization in a growing preterm also can cause increase in alkaline phosphatase but this is not associated with low phosphate. Babies on nasojejunal feeds are on continuous feeds as jejunum is not capable of handling large volume at a time. Babies who are less than 32 weeks are started on initially orogastric feeding and then transition to spoon and breastfeeding done. Babies more than 34 weeks can be tried on direct breastfeeding though some babies may need supplemental spoon feeding. It is required for vision, immune system, normal lung growth and respiratory tract epithelial system. Iron Poor neurodevelopmental outcome has been reported in iron deficiency anemia, however excess dose may be associated with increased risk of infection, poor growth, and disturbed other mineral metabolism. Iron is a pro-oxidant and excess non-protein bound iron produces free radicals which is harmful and can increase the risk of retinopathy of prematurity. In babies who received multiple blood transfusions, supplementation can be delayed. The Newborn Infant Oromotor stimulation enhances oral feeding skills of preterm infants specially the one with prolonged illness requiring orogastric feeding. Fortified Human Milk Multicomponent human milk fortifier provides extra calories, proteins, minerals and vitamins. Feed Intolerance Feed intolerance is a very common symptom in preterm neonates mostly due to gut pathology, sepsis and electrolyte disturbances. Preterm Formula In absence of donor breastmilk or inadequate breastmilk, preterm formula is the next choice of feeding in growing preterm infants. They provide nearly adequate calorie, protein, vitamins and minerals if fed in full volume. Animal Milk Though animal milk is used very frequently in our country after discharge, there is no study on their impact on growth and neurodevelopment. However the processing causes some loss of immune function and nutritional composition. As pasteurization causes loss of bile salt stimulated lipase, fat absorption is less with donor milk and causes slow growth but still it is associated with long-term advantage. Donor human milk is preferred over preterm formula as risk of gut associated problem is less with human milk. Donor human milk also probably has similar protective role when compared to formula though poor weight gain is a concern with donor milk. Babies who are not on fortifier or preterm milk should receive multivitamins, calcium, phosphate and vitamin D supplements as per recommended doses. There is no role of prelacteal feeding in the form of water or dextrose as it has a negative impact on breastfeeding. Once the babies are off fortification or changed over to term formula or other types of milk, supplements to be provided. There is significant controversy regarding initiation and advancement of feeding in these babies. Multivitamins are continued at least till 6 months of life and calcium supplements are given till at least 40 weeks postconceptional age in larger preterm neonates. In small preterm babies who could not be stared on adequate calcium or phosphate early, supplements are continued for a longer time along with monitoring of metabolic parameters. Iron is continued at least till the age of 1 year and to be stopped depending on adequacy of complementary feeding. It is also unknown about their long term immunological effects and rarely infection by probiotic agents has been reported. Hence before recommending routine use of probiotics in our country, some country specific trials are required and long term safety needs to be established. Breastmilk contains several probiotics and more than 130 prebiotics and a combination of both exert a favorable effect in the preterm gut.

Buy ofloxacin 200 mg fast delivery

Sulfasalazine and its metabolite antibiotic resistance in agriculture buy cheap ofloxacin 400mg, sulfapyridine, readily cross the placenta to the fetal circulation (6,7). Neither of these levels was sufficient to cause significant displacement of bilirubin from albumin (7). Kernicterus and severe neonatal jaundice have not been reported following maternal use of sulfasalazine, even when the drug was given up to the time of delivery (7,8). Caution is advised, however, because other sulfonamides have caused jaundice in the newborn when given near term (see Sulfonamides). In a 2000 case­control study, the effect of folic acid supplementation on the risks for certain congenital defects were examined (17). Supplementation reduced the teratogenic risk from sulfasalazine and similar acting folic acid antagonists. Sulfasalazine may adversely affect spermatogenesis in male patients with inflammatory bowel disease (18,19). Sperm counts and motility are both reduced and require 2 months after the drug is stopped to return to normal levels (18). Unmetabolized sulfasalazine was detected in only one of the studies (milk:plasma ratio of 0. No adverse effects were observed in the 16 nursing infants exposed in these reports (6,16,20). The mother was a slow acetylator with a blood concentration of sulfapyridine of 42. The acetylation phenotype of the infant was not determined, but his blood level of sulfapyridine was 5. Based on the above report, the American Academy of Pediatrics classifies sulfasalazine as a drug that has been associated with significant effects in some nursing infants and should be given to nursing mothers with caution (22). Placental transfer of sulphasalazine and sulphapyridine and some of its metabolites. The influence of inflammatory bowel disease and its treatment on pregnancy and fetal outcome. Bloody diarrhea-a possible complication of sulfasalazine transferred through human breast milk. One study has found associations with birth defects, but a causative association cannot be determined with this type of study and they may have been due to other factors, particularly if trimethoprim was combined with the sulfonamide. Because of the potential toxicity to the newborn, these agents should be avoided near term. Although there are differences in their bioavailability, all share similar actions in the fetal and newborn periods, and they will be considered as a single group. Sulfamethoxazole was teratogenic (primarily cleft palates) in rats given oral doses of 533 mg/kg (1). The sulfonamides readily cross the placenta to the fetus during all stages of gestation (2­10). Equilibrium with maternal blood is usually established after 2­ 3 hours, with fetal levels averaging 70%­90% of maternal levels. Significant levels may persist in the newborn for several days after birth when given near term. The primary danger of sulfonamide administration during pregnancy is manifested when these agents are given close to delivery. Toxicities that may be observed in the newborn include jaundice, hemolytic anemia, and, theoretically, kernicterus. Severe jaundice in the newborn has been related by several authors to maternal sulfonamide ingestion at term(11­16). Premature infants seem especially prone to development of hyperbilirubinemia (15). However, a study of 94 infants exposed to sulfadiazine in utero for maternal prophylaxis of rheumatic fever failed to show an increase in prematurity, hyperbilirubinemia, or kernicterus (17). Hemolytic anemia has been reported in two newborns and in a fetus following in utero exposure to sulfonamides (11,12,16). In the case involving the fetus, the mother had homozygous glucose-6-phosphate dehydrogenase deficiency (16). She was treated with sulfisoxazole for a urinary tract infection 2 weeks before delivery of a stillborn male infant. In utero, the fetus clears free bilirubin by the placental circulation; however, after birth, this mechanism is no longer available. Unbound bilirubin is free to cross the blood­brain barrier and may result in kernicterus. Although this toxicity is well known when sulfonamides are administered directly to the neonate, kernicterus in the newborn following in utero exposure has not been reported. Most reports of sulfonamide exposure during gestation have failed to demonstrate an association with congenital malformations (10,11,18­24). In contrast, a retrospective study of 1369 patients found that significantly more mothers of 458 infants with congenital malformations took sulfonamides than did mothers in the control group (25). A 1975 study examined the in utero drug exposures of 599 children born with oral clefts (26). In two reports, investigators associated in utero sulfonamide exposure with tracheoesophageal fistula and cataracts, but additional descriptions of these effects have not appeared (29,30). A mother treated for food poisoning with sulfaguanidine in early pregnancy delivered a child with multiple anomalies (31). The author attributed the defects to use of the drug, but a relationship is doubtful. The Collaborative Perinatal Project monitored 50,282 mother­child pairs, 1455 of whom had 1st trimester exposure to sulfonamides (32, pp. Several possible associations were found with individual defects after anytime use, but independent confirmation is required: ductus arteriosus persistens (8 cases), coloboma (4 cases), hypoplasia of limb or part thereof (7 cases), miscellaneous foot defects (4 cases), urethral obstruction (13 cases), hypoplasia or atrophy of adrenals (6 cases), and benign tumors (12 cases) (32, pp. In a surveillance study of Michigan Medicaid recipients involving 229,101 completed pregnancies conducted between 1985 and 1992, 131 newborns had been exposed to sulfisoxazole, 1138 to sulfabenzamide vaginal cream, and 2296 to the combination of sulfamethoxazole-trimethoprim during the 1st trimester (F. No anomalies were observed in four other categories of defects (spina bifida, polydactyly, limb reduction defects, and hypospadias) for which data were available. The data for sulfisoxazole and sulfabenzamide do not support an association between the drug and congenital defects. In contrast, a possible association was found between sulfamethoxazole-trimethoprim and congenital defects (126 observed/98 expected; 5. A 2009 report from the National Birth Defects Prevention Study estimated the association between antibacterial agents and >30 selected birth defects (33). The authors conducted a population-based, multiple site, case­control study of women who gave birth to an infant with 1 of >30 selected defects. Significant associations with multiple selected birth defects were found (total number of exposed cases/controls) with sulfonamides (145/42) (probably combined with trimethoprim) and nitrofurantoin (150/42). The adjusted odds ratios and 95% confidence intervals (in parentheses) for sulfonamides were anencephaly 3. Significant associations (total number of exposed cases/controls; number of associations) also were found for penicillins (716/293; 1), erythromycins (202/78; 2), cephalosporins (128/47; 1), quinolones (42/14; 1), and tetracyclines (36/6; 1). The results for quinolones and tetracyclines, however, were based on small numbers of exposed cases and controls (33). As with all retrospective case­control studies, the data can determine associations, but not causative associations (33). Moreover, several limitations were identified by the authors, including spurious associations caused by the large number of analyses, interviews conducted 6 weeks to 2 years after the pregnancy making recall difficult for cases and controls, recall bias, and inability to distinguish between drug-induced defects and defects resulting from the infection (33). Milk levels of sulfanilamide (free and conjugated) are reported to range from 6 to 94 mcg/mL (4,34­39). Milk levels often exceeded serum levels and persisted for several days after maternal consumption of the drug was stopped. One author found reports of diarrhea and rash in breastfed infants whose mothers were receiving sulfapyridine or sulfathiazole (7). Based on these data, the nursing infant would receive approximately 3­4 mg/kg/day of sulfapyridine, an apparently nontoxic amount for a healthy neonate (17). Sulfisoxazole, a very water-soluble drug, was reported to produce a low milk:plasma ratio of 0. The total amount of sulfisoxazole recovered in milk during 48 hours after a 4-g divided dose was only 0. Although controversial, breastfeeding during maternal administration of sulfisoxazole seems to represent a very low risk for the healthy neonate (41,42).

Buy ofloxacin 200 mg line

A 1994 review concluded that pregnant women should be vaccinated antibiotic vitamin buy ofloxacin 200mg overnight delivery, preferably after the 1st trimester, if exposure to a yellow fever epidemic is unavoidable (7). Although the experience with valacyclovir in early pregnancy is limited, many studies have reported the use of acyclovir during all stages of pregnancy (see also Acyclovir). Based on the combined data, there is no evidence of a major risk to the human fetus from valacyclovir or acyclovir. It is used in the treatment of herpes zoster (shingles) and recurrent genital herpes simplex. Reproduction studies were conducted in rats and rabbits during organogenesis with doses producing concentrations 10 and 7 times human plasma levels, respectively (2). The active metabolite, acyclovir, readily crosses the human placenta (see Acyclovir). An abstract and study, both published in 1998, compared the pharmacokinetics of valacyclovir and acyclovir in late pregnancy (3,4). The Valacyclovir Pregnancy Registry listed 157 prospective reports of women exposed to the oral antiviral drug during gestation covering the period from January 1, 1995, through April 30, 1999 (5). Among the 111 (1 set of twins) known outcomes, 29 had earliest exposure in the 1st trimester and their outcomes were 5 spontaneous abortions, 2 induced abortions, 1 infant with a birth defect (talipes), and 21 infants (including the twins) without birth defects. When the earliest exposure was in the 2nd trimester, 31 pregnancies were enrolled and their outcomes were 2 stillbirths, 2 infants with birth defects (fingers and toes fused-extensive webbing; small cleft in front gum), and 27 without birth defects. In the remaining 51, the earliest exposure occurred in the 3rd trimester, with 1 infant with a dermal sinus tract and 50 without birth defects (5). A total of 34 retrospective reports of valacyclovir exposure during pregnancy were submitted to the Registry (5). Two of the exposures occurred during an unspecified gestational time and both resulted in live births without defects. The outcomes of these pregnancies were three spontaneous losses, eight induced abortions, and three infants without birth defects. For the pregnancies whose earliest exposure was in the 2nd trimester (N = 4) or 3rd trimester (N = 14), there was 1 birth defect (2nd trimester exposure) and 17 infants without defects (5). She delivered a full-term, healthy female infant who was treated prophylactically with oral acyclovir for 1 month. No abnormalities were detected during a neurologic examination at 8 months of age (6). There were no differences between the groups in terms of delivery and neonatal outcomes (7). A 2009 review of genital herpes concluded that the benefits from the use of acyclovir or valacyclovir for the treatment of the virus in pregnancy far outweighed the potential fetal risks (8). Because there was no evidence to suggest a risk of major defects with acyclovir, the reviewers also concluded that the pro-drug valacyclovir, even though the pregnancy experience was limited, could be viewed similarly. A 2010 study used a population-based historical cohort of 837,795 liveborn infants in Denmark to determine if there were associations between 1st trimester exposure to acyclovir, valacyclovir, and famciclovir and major birth defects (9). Subjects were excluded if they had chromosomal abnormalities, genetic syndromes, birth defect syndromes, or congenital viral infections. The authors concluded that 1st trimester exposure to valacyclovir and acyclovir was not associated with an increased risk of major birth defects (9). The authors of an accompanying editorial thought that the large number of exposures during organogenesis without an overall increased risk of major defects was reassuring, especially for acyclovir. However, more data were needed to examine the associations with individual defects (10). Acyclovir is concentrated in human milk with milk:plasma ratios in the range 3­4 (see Acyclovir). In a 2002 study, five healthy postpartum women who were breastfeeding were given valacyclovir (500 mg) twice daily for 7 days (11). Maternal serum and milk samples were collected after the first dose, on day 5, and 24 hours after the last dose. The peak milk concentration occurred 4 hours after the first dose (milk:serum ratio 3. Because acyclovir has been used to treat herpesvirus infections in the neonate, and because of the lack of adverse effects in reported cases in which acyclovir was used during breastfeeding, the American Academy of Pediatrics classifies acyclovir as compatible with breastfeeding (see Acyclovir). Moreover, as a natural, unregulated product, the concentration, contents, and presence of contaminants in valerian preparations cannot be easily determined. Because of this uncertainty and the potential for cytotoxicity in the fetus and hepatotoxicity in the mother, the product should be avoided during pregnancy. The risk to a fetus from short-term or inadvertent use during any part of gestation, however, is probably low, if it exists at all. A large number of preparations containing valerian are commercially available (4). The herb is used as a sedative and hypnotic for anxiety, restlessness, and sleep disturbances (1­5). Other pharmacologic claims that have been made for valerian include antispasmodic, anticonvulsive, antidepressant, and antihypertensive properties (2­4). The extracts and root oil have also been used as flavorings for foods and beverages (3). Although the specific agents responsible for the effects of valerian are unknown, as is the mechanism of action, three classes of compounds have been identified: a volatile oil that contains sesquiterpenes; nonglycosidic iridoid esters (known as valepotriates); and alkaloids (3,4). Of these, the valepotriates, found primarily in the roots, are most likely responsible for the sedative action, but components from the other two classes probably contribute as well (3,4). Because these compounds produce central nervous system depression, they should not be used with other depressants, such as alcohol, benzodiazepines, barbiturates, or opiates (1,2,5). Moreover, nonpregnant adult human hepatotoxicity has been associated with short-term use. Long-term use in a male has also been associated with benzodiazepine-like withdrawal symptoms resulting in cardiac complications and delirium (7). Reproductive studies in animals with valerian have not shown antiovulation, antifertilization, or embryotoxic effects (8). Toxicity in mice was characterized by ataxia, hypothermia, and increased muscle relaxation. The cytotoxic activities of three valepotriate compounds, valtrate, didrovaltrate, and baldrinal (a degradation product of valtrate), in cultured rat hepatoma cells were described in a 1981 reference (9). Both valtrate and didrovaltrate demonstrated much greater cytotoxic activity than did baldrinal, with rapid and irreversible toxicity. Five surviving mice were then bred with normal male mice 50 days after treatment with didrovaltrate. In a 1988 report, two cases of attempted suicide with valerian dry extract plus other drugs were described (10). Two additional cases of self-poisoning with valerian were described in 1987 by the same group responsible for the above report (11). In both cases exposure occurred early in gestation, with ingestion of 5 and 2 g of valerian at 3 and 4 weeks of fetal development, respectively. For the reasons cited above, the use of this herbal product should be avoided during breastfeeding. Teratologic evaluation of 178 infants born to mothers who attempted suicide by drugs during pregnancy. For ganciclovir, human pregnancy experience has not shown toxicity, but the number of cases is very limited. The animal data for ganciclovir are suggestive of high embryo­fetal risk because carcinogenic, mutagenic, teratogenic, and embryotoxic effects have been observed. Some of the embryos or fetuses exposed to the virus will be damaged and the development of later toxicity in childhood is an additional concern. However, the prevention of these in utero infections by ganciclovir has not been proven (see Ganciclovir). Plasma protein binding of valganciclovir is not relevant because of its rapid metabolism to ganciclovir, but binding of ganciclovir is very low (1%­2%). The elimination half-life of ganciclovir after valganciclovir administration is about 4. Reproduction studies in animals have been conducted with the active metabolite ganciclovir (1) (see Ganciclovir).

Limited information is available on pregnancies complicated by type I Gaucher disease and treated with similar enzyme-replacement therapies antibiotics for uti medscape buy ofloxacin overnight delivery, alglucerase or imiglucerase, and these data have not suggested fetal risk. Pregnancy may exacerbate existing disease or result in new disease manifestations, but the limited human data for alglucerase and imiglucerase suggest that treatment during pregnancy may reduce risks for spontaneous abortion and bleeding complications. Velaglucerase alfa replaces the endogenous enzyme -glucocerebrosidase with a product produced by gene activation technology in a human cell line. The enzyme has the same amino acid sequence as the naturally occurring human enzyme. After infusion, the terminal elimination half-life ranges between 5 and 12 minutes (1). Developmental and reproductive toxicology studies have been conducted in rats and rabbits at doses of 17 and 20 mg/kg, respectively. It is unclear how these compare with recommended human doses but they appear to be substantially higher than the maximum recommended human dose of 60 U/kg on a mg/kg basis. No maternal or developmental treatment-related effects were demonstrated in either species (1). The carcinogenic and mutagenic potential of velaglucerase alfa has not been studied. Reproductive toxicity studies in male and female rats revealed no evidence of impaired fertility (1). The high molecular weight (about 63,000) and the short terminal half-life suggest that placental transfer may be limited. The high molecular weight (about 63,000) and the short terminal half-life suggest that excretion into milk will be limited. Moreover, the glycoprotein probably is destroyed in the digestive tract and even if small amounts are transferred into breast milk, the enzyme is unlikely to reach the systemic circulation of a breastfed infant. The female Gaucher patient: the impact of enzyme replacement therapy around key reproductive events (menstruation, pregnancy and menopause). The fetus had growth restriction, but the reduced growth had began a week before treatment was started. The animal data suggest low risk, but the exposures were around the clinical exposure. If the drug is used in pregnancy, the patient should be informed of the potential risk to the fetus. Following a single oral dose, mean data from plasma samples analyzed over a 48-hour period found that vemurafenib and its metabolites represented 95% and 5%, respectively, of the components in plasma. The median elimination half-life is about 57 hours (range about 30­120 hours) (1). In these species, no evidence of teratogenicity was observed at doses resulting in exposures up to about 1. However, the drug increased the development of cutaneous squamous cell carcinomas in patients in clinical trials. Although vemurafenib-induced impairment of fertility in animals has not been studied, no histopathological findings were observed in the reproductive organs of male and female rats and dogs during repeat-dose toxicological studies (1). In the report below, infant levels were about 45% of the maternal concentration at birth. The molecular weight (about 490), minimal metabolism, and long elimination half-life are consistent with this report, but the high plasma protein binding might have limited the exposure. A 2013 case report described the use of vemurafenib in a pregnant woman with malignant melanoma (2). The patient rapidly responded to the treatment with a decrease in pain and new metastasis disappeared. Fetal growth restriction (of the body, not the head) that had started a week before initiation of vemurafenib continued and a cesarean section was performed in the 30th week of gestation. Blood concentrations of vemurafenib at birth in the mother, umbilical cord, and 1028-g infant were 24. The infant had uncomplicated stay in the neonatal ward and was eventually discharged home in good condition. The molecular weight (about 490), minimal metabolism, and long elimination half-life suggest that the drug will be excreted into breast milk, but the high plasma protein binding might limit the exposure. The most common adverse reactions in adults (30%) treated with the drug are arthralgia, rash, alopecia, fatigue, photosensitivity reaction, nausea, pruritus, and skin papilloma (1). Moreover, there was a 24% incidence of cutaneous squamous cell carcinoma in clinical trials (1). Thus, there is potential risk to a nursing infant and, if the mother requires the drug, the best course would be to not breastfeed. When rats were given the same maximum dose during pregnancy through weaning, however, there was a decrease in pup weight and an increased number of stillbirths and pup deaths during the first 5 days of lactation. These results are consistent with the molecular weight of venlafaxine (about 314), the minimal protein binding, and the moderately long elimination half-lives. A 1994 review of venlafaxine included citations of data from the clinical trials of this drug involving its use during gestation in 10 women for periods ranging from 10 to 60 days (3), apparently during the 1st trimester. No adverse effects of the exposure were observed in four of the infants (information not provided for the other six exposed pregnancies). In the cases exposed to venlafaxine, there were two infants with birth defects (hypospadias; neural tube defect and clubfoot). The results suggested that venlafaxine does not increase the rates of major congenital defects over that expected in a nonexposed population (4). The use of venlafaxine late in the 3rd trimester may result in functional and behavioral deficits in the newborn infant. The product information was changed by the manufacturer in 2004 to reflect this potential developmental toxicity (1). The observed toxicities include respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremor, jitteriness, irritability, and constant crying. The clinical features are consistent with either a direct toxic effect or drug discontinuation syndrome and, occasionally, may resemble a serotonin syndrome. The complications may require prolonged hospitalization, respiratory support, and tube feeding (1). The typical neonatal syndrome consisted of central nervous system, motor, respiratory, and gastrointestinal signs that were mild and usually resolved within 2 weeks. Because of the small numbers, a dose­response analysis could only be conducted with paroxetine (7) (see Paroxetine). A 2004 report described the pregnancy outcomes of 11 women who had taken venlafaxine (doses 75­225 mg/day) during the 1st trimester (8). One patient also took venlafaxine for 3 weeks in the 2nd trimester, but none of the women were exposed in the second half of pregnancy. The outcomes included two induced abortions and nine healthy infants that were doing well at 12 months of age (8). In a 2006 case, a 2-day-old infant, exposed throughout pregnancy to venlafaxine (375 mg/day), exhibited signs and symptoms of lethargy, jitteriness, rapid breathing, poor suck, and dehydration. Another 2006 report described seizures in two infants after in utero exposure to venlafaxine (10). At 30 minutes, the otherwise normal but depressed infant exhibited lip smacking and extensor limb posturing associated with bradycardia and hypertension. The generalized hypertonia and hyperreflexia was treated with phenobarbital for 2 weeks. Breastfeeding was started but the infant had bilious vomiting and, at 24 hours of age, developed multifocal myoclonic seizures involving all limbs. The antidepressants, number of subjects, and daily doses in the exposed group were paroxetine (46; 5­40 mg), fluoxetine (10; 10­40 mg), venlafaxine (9; 74­150 mg), citalopram (6; 10­30 mg), sertraline (3; 125­150 mg), and fluvoxamine (2; 50­150 mg). There were six infants in each group with congenital malformations, but the drugs involved were not specified (11). Venlafaxine was the only antidepressant used in 501 pregnancies (505 infants), whereas 12 other pregnancies (12 infants) were exposed to a combination of venlafaxine plus another antidepressant (mianserin, mirtazapine, or reboxetine). The neurobehavior of the exposed neonates (N = 38) was compared with a nonexposed, matched control group (N = 18) in six areas: habituation, social-interactive, motor, range, regulation, autonomic. There were no significant differences in neurobehavior between the two antidepressant groups (2). A prospective cohort study evaluated a large group of pregnancies exposed to antidepressants in the 1st trimester to determine if there was an association with major malformations (15). In addition to the 154 venlafaxine cases, the other cases were 113 bupropion, 184 citalopram, 21 escitalopram, 61 fluoxetine, 52 fluvoxamine, 68 mirtazapine, 39 nefazodone, 148 paroxetine, 61 sertraline, and 17 trazodone. There were two major anomalies in the venlafaxine group: hypospadias and a club foot.

The severe malformations induced by thalidomide may involve defects of the limbs, axial skeleton, head and face, eyes, ears, tongue, teeth, central nervous, respiratory, cardiovascular, and genitourinary systems, and the gastrointestinal tract. The neurological complications may include severe mental retardation secondary to sensory deprivation. The agent was recently approved for use in the United States for the first time, making its debut in 1999. Thalidomide was one of the first drugs that was clearly shown to be a human teratogen and probably has caused more known severe malformations in humans than any other drug. A large number (>30) of animal (mice, rats, rabbits, and monkeys) reproduction studies conducted with thalidomide were reviewed in a 1976 reference (2). Embryolethality and teratogenicity (structural and/or functional abnormalities) were noted commonly in some species. Evidence of significant thalidomide teratogenicity was found in monkeys, but in mice and rats, limb reduction defects were not observed and, in some cases, there was no evidence of teratogenicity. Amelia and micromelia were noted in two mouse fetuses and a limb defect in another that closely resembled the defects observed in humans, but these reports were considered inconclusive (2). In a 1983 study with rats, however, increased rates of both embryolethality and congenital defects involving the skeleton (ribs and spine) and eyes (ophthalmorrhexis and microphthalmia) were observed (3). The authors speculated that the difference in outcome between their study and previous experimental work with rats was possibly due to hydrolysis of the drug before administration, the use of toxic solvents that masked the teratogenic effect of thalidomide, or the low solubility of thalidomide in the solvent that prevented delivery of an effective dose to the target site (3). Experiments in rabbits have consistently revealed fetal limb malformations that are very similar to those seen in human infants exposed in utero to thalidomide (4­8). Other anomalies noted in rabbit fetuses included hemangioma of the nose and defects of the skull, nostril, external genitalia, and tail (6). Another study with rabbits observed limb anomalies, arthrogryposis, dysplasia of the kidneys and gallbladder, cleft palate, hernia, and gastric hypoplasia (8). Experiments with chick embryos demonstrated that thalidomide induced cardiovascular anomalies in this species (9). Several reviews have described the various human systems affected by thalidomide-induced embryopathy (10­19). One of these reviews presented the pregnancy history of two children (twins), born in the United States, who had very different severity of thalidomide embryopathy (10). The first twin, 2211-g female, was born with duodenal atresia, a rectoperineal fistula, and hypoplastic, dislocated thumbs (right thumb worse than left). The other twin, a 2240-g male, had phocomelia of both upper extremities and a midline hemangioma on the forehead. Perhaps the best description of the spectrum of congenital defects caused by thalidomide was written by Newman (16,17). The limb reduction defects are bilateral, usually grossly symmetric, and upper limb anomalies are commonly associated with lower limb defects. Shoulder and hip malformations occur with increasing severity of upper limb defects. Vertebral defects include an increased incidence of progressive ossification of the anterior spinal ligaments that converts the sacral and lumbar vertebral bodies into one bone mass, loss of distal segment of the sacrum, and spondylolisthesis. A nonspecific facial asymmetry may occur, as well as tooth hypoplasia and a deficiency in the number of teeth. There may be a hypoplastic nasal bridge with an expanded nasal tip, and choanal atresia can affect one or both nostrils. Laryngeal and tracheal anomalies and abnormal lobulation of the lungs have been observed. Ocular defects include refractive errors, pupillary abnormalities, muscle dysfunction, coloboma, microphthalmos, cataracts, and abnormalities of all three components of the oculomotor nerve. Ear defects are frequently associated with ocular malformations, as is facial nerve palsy. The defects of the ears include external, middle, and internal anomalies which are frequently associated with deafness (either conductive, neural, or both). A midline capillary hemangioma or nevus of the nose and philtrum have been described, but may fade as the child grows older. Cardiac defects, commonly of the conotruncal region, occur frequently and are a major cause of early death (30% at birth, 6% in survivors). Gastrointestinal tract defects include atresia and stenosis, and absence of the gallbladder and appendix. Genitourinary malformations involve the kidneys (ectopic, horseshoe, hydronephrosis, and double ureter), double vagina, and cryptorchism (16,17). Although a wide range of indications was promoted for the drug, it was primarily used as a sedative and tranquilizer. Because of the concern over birth defects, thalidomide was withdrawn from the market in most countries in late 1961 (21). In 1961, two cases of congenital defects of the limbs were presented at a German pediatric meeting (22). A brief 1961 correspondence, however, was the first published English language article to describe birth defects that were suspected as being induced by thalidomide (24). McBride (24) had noted an approximate 20% incidence of polydactyly, syndactyly, and limb reduction defects consisting of abnormally short femora and radii in infants exposed in utero to thalidomide. In early 1962, Lenz (23) estimated that 2000­ 3000 thalidomide-exposed babies had been born in West Germany since 1959. A number of communications have been published that describe the types of congenital malformations caused by thalidomide (10,15­19,23­81): Thalidomide Embryopathy Limb Defects Upper and lower limbs (bilateral amelia or phocomelia; absence or hypoplasia of radius/ulna and/or tibia/fibula; femoral hypoplasia; preaxial aplasia of upper and lower limbs; absence of the fingers and/or toes; thumb defects such as duplication, hypoplasia, and triphalangism; duplication of big toe and triphalangism) (10,15­19,23­38,40,41,45­47,49­51,54­59,61­66,68,70,71,74­81) Osteochondritis of femoral head (Legg-Calve-Perthes disease) (possibly a late complication that results from growth disturbance of the upper end of the femur; appeared in early childhood) (51) Knee joints (laxity of cruciate ligaments) (16,17,61) Other Skeletal Defects Spine (ossification of sacral and lumbar vertebrae, loss of distal segment of sacrum, spondylolisthesis, scoliosis) (15­18,35­37,40,43,49,50,58,61,66,71,78,79) Shoulder (hypoplasia/dysplasia of glenoid cavity, dysplasia of neck of scapula, altered humeral head) (16,17,19,61) Hip/pelvis (dislocation, pelvic girdle hypoplasia) (16,17,19,35,51,59,61,66,78,79) Jaw (69,74) Craniofacial Eye (refractive errors, pupil, motility, coloboma of the iris, uvea, lens, and choroid, microphthalmos, cataracts, glaucoma, crocodile-tear syndrome) (15­19,25,30,33,36,37,40,45­47,49,50,62,63,65,66,68,70­77) Ear (anotia, microtia, low set, middle and internal ear, deafness) (15­19,23,25­27,29,30,33,35,37,39,41,43­45,48,53,56­58,61­68,70,73 Face/skull (face-asymmetrical; skull-rhomboid shape) (16,17,58,69) Tongue (dysplasias of lingual frenulum in the form of an ankyloglossia [tongue-tie] or a shortened, sinew-shaped frenulum; grooved point of tongue [bifid tongue]) (16,69) Nose (hypoplastic nasal bridge with expanded nasal tip) (16,17,19,58,66) Choanal atresia (16­19,29,37,62,65,70,71,75) Teeth (hypodontia, hyperdontia, malformed crown, enamel hypoplasia, discoloring, malocclusion, missing teeth) (16­18,58,60,69,75) Midline hemangioma or nevus (nose, upper lip, frontal area) (10,16,17,23,25,30,33,35,45,46,57,58,60,65,66,71) Central Nervous System Facial nerve palsy (often associated with eye and ear anomalies) (15­19,35,39,43,61,63,68,71,73,75­77) Hydrocephalus (37,57,65,73) Spina bifida occulta (16,17,78,79) Meningomyelocele (16,17,35) Autism (18,77) Epilepsy (15,16,76,77) Marcus Gunn phenomenon or jaw winking syndrome (16,19) Crocodile-tear syndrome (see Eye) Major Organ Systems Respiratory system (laryngeal and tracheal abnormalities, abnormal lobulation of lungs) (16,17,19,29,33,36,37,49,62,65,66,74,75) Cardiovascular (ventricular septal defect, atrial septal defect, tetralogy of Fallot, cor triloculare, pericardial effusion, hypertrophy of atrium and ventricle, coarctation of aorta, systolic murmurs) (16­19,23,25,30,33,35­37,39,40,42,43,45,57,61,62,65,66,70,73,75,76) Gastrointestinal tract Esophageal atresia (23,29,30,37,74) Duodenal atresia (10,16,19,23,29,30,33,35,37,49,61,62,66,70) Common bileduct atresia (33,66) Anal atresia (16,18,19,23,29,30,33,35,37,44,61,62,66,75) Rectoperineal fistula (10) Malrotation (25,30,33,35,66) Stenosis (16­19,25,30,37,40,45,46,53,61,62,65,66,70,76) Abnormal lobulation of liver (33,37) Aplasia of appendix (16,17,19,23,29,30,33,37,40,46,52,53,59,65,66) Aplasia of cecum (33) Aplasia of gallbladder (16,17,19,23,30,33,36,49,57,65,66) Rectoperineal fistula (10) Genitourinary system Unspecified (25,30,33,37,75) Renal abnormalities (16­19,29,35­37,46,57,59,61,62,65,66,70,74,75,81) Defects and duplication of ureters (16,17,19,37,81) Aplasia of fallopian tube (62) Defects of uterus and/or vagina (16,17,19,33,37,55,62,65,66,80) Penile maldevelopment (65) Cryptorchism (16,17,19,25,36,61,65,66) Other Excessive sweating (52,54) Inguinal hernias (16,17,19,61,66) Cleft lip with or without cleft palate has occasionally been observed in newborns with thalidomide embryopathy (35,44,48,49,65,66,69­71), but it is not thought to be related to thalidomide exposure (19). In 1962, Lenz and Knapp (62) reviewed the fetal effects of thalidomide that were known at the time. Of 293 cases known to the authors or from published reports, the approximate percentage of each defect was arms only (52%); arms and legs (28%); arms, legs, and ears (3%); arms and ears (6%); ears only (7%); legs only (2%); and other malformations (3%). The anomalies observed in the eight infants grouped as "other malformations" included one case each of a right polycystic kidney with aplasia of the left kidney, aplasia of left fallopian tube and left cornu of the uterus, multicystic kidneys, anal stenosis with hydronephrosis, fistula of the neck, congenital heart disease, choanal atresia, and anal atresia (62). In addition, malformations that accompanied those of the limbs and ears were pyloric stenosis, duodenal stenosis, duodenal atresia, cardiac defect, microphthalmos, anophthalmia, imperforate anus, and choanal atresia (62). Two additional review articles by Lenz, focusing on thalidomide-induced defects, appeared in 1966 (63) and 1971 (64), one with a commentary by Warkany (82). In 1963, Japanese investigators reported phocomelia and other malformations in 10 cases (5 live infants and 5 stillbirths or early neonatal deaths) (65). Another investigator evaluated 160 cases of thalidomide embryopathy that occurred in Japan (66). Of the 160 cases, 99 had a welldocumented history of thalidomide intake in early pregnancy. Of these, 70% had defects of the arms only; 14% of arms and legs; 5% of the arms, legs, and ears; 5% of the ears only; 3% of the arms and ears; and 3% of other organs (66). In 41 of the cases with malformations of the limbs and ears, an autopsy found multiple other defects of various organ systems that were similar to those reported by Lenz and Knapp (see reference 62) (66). The importance of early examinations for ear anomalies, especially for resulting hearing impairment, was emphasized in a study published in 1965 (67). The author had observed 14 cases of bilateral congenital meatal atresia in thalidomide-exposed infants at his center, but he was aware of 50 such cases throughout England.
