Culture Collection A phlebotomist working in a clinic or outpatient setting may be involved in the collection of various types of cultures symptoms insulin resistance best order for copegus. It can also be required as a postvasectomy specimen to determine if the vasectomy was successful. Also avoid ejaculation for at least 3 days prior to collection of the semen sample. Arrange collection so the specimen can be delivered to the laboratory between the hours of 7:00 A. Condoms and lubricants must not be used, as they often contain spemicidal agents that can kill or injure sperm. A container other than the container supplied by the laboratory should not be used. If a portion of the specimen is lost, another specimen will have to be collected after another 3-day abstinence period. After the specimen is obtained, it is important to deliver it to the laboratory within 30 minutes and to protect it from any extremes of temperature. Placing the container in a shirt or pants pocket generally ensures the proper temperature. Upon completion of the testing, the results will be sent to your physician, who will explain the significance to you. What is the preferred method of preservation of a urine specimen, if it cannot be run within an hour What will be affected by a delay7 Semen Collection Semen samples are collected to determine the number and activity of sperm contained in the semen (Procedure 9-9). It is also required as a postvasectomy sample to determine if the vasectomy was successful. Time constraints between the time of collection and submission to the laboratory are critical to accurately determine the number and activity of sperm that might be contained in the semen. Materials: Gloves Hand disinfectant Sterile collection container Self-sealing bag label and requisition Patient Procedure: 1. Arrange the collection so the sample can be delivered to the laboratory at a time the laboratory is able to accept the sample. Do not use any container for collection other than the container you were given when you received these instructions. After the sample is obtained, it is important to deliver it to the laboratory within 30 minutes and to protect it from any extremes of temperature. Bacterial count will increase to the level that indicates a major urinary tract infection. Delay in obtaining the gray urine culture tube will offset the ratio of d ifferent bacteria in the urine. If there is not enough volume to fill the gray tube, immediately refrigerate the urine cup until it can be sent on ice with the next courier. Red/yellow (tiger) top tube-72 Hour Stability Tiger top urine tube can be used on ly for urinalysis. Yellow top urine tube, round bottom or conical bottom-Stability varies depending on the test Yellow top urine tube, no preservative. Describe in detail the nine types of urine collections listed in this chapter, how they are collected, what they are collected for, and any specific characteristics of the samples in terms of analysis. Sample is collected from the patient, and the temperature of urine is checked to determine if urine is fresh. Sample must be cultured within 1 hour of collection and refrigerated or a special preservative container used. Helpful Hint Always verify what test(s) will be run on the sample before using a preservative. Preservatives should always be used with caution because the preservative could alter the results of some of the testing performed on the urine. Chemical preservatives can be used as an alternative for routine urinalysis and in most 24-hour urines that cannot be refrigerated. These kits provide a cleansing towelette for the patient and a sterile urine collection cup. The tubes can then be sent to the appropriate laboratory with the urine preserved immediately after collection. A urine test would miss drug use if she stopped drug use as the due date was close. It may take several days for meconium to be expelled the umbilical cord is available upon delivery. This will improve the turnaround time of results so umbilical testing can reveal neonatal intoxication sooner than other methods. The phlebotomist will not collect these types of samples but must be knowledgeable in the sample processing of such samples. Which of the following would be the antiseptic(s) of choice for blood culture collection One phlebotomist collects the samples using a finger puncture, and the other phlebotomist collects the samples with a venipuncture. H ow will this cause a problem with the sequential results7 Copyright 2018 Cengage Learning. Chemistry tests for fats and urobilinogen can be conducted on feces this testing usually requires at least a 24-hour collection. The sample is collected in metal or plastic paint cans for delivery to the laboratory. There are also commercially prepared containers that laboratories may purchase for stool collection. Do the instruction in the privacy of a separate room and not where other patients can hear the conversation. The first question most patients have is how they are going to collect the sample. A large collection bowl (hat) sits on the toilet bowl and then the seat of the toilet is lowered to hold the collection bowl in place. The paLiem will defecate as normal and should should make sure Lhe collecLion bowl is placed back far enough to avoiding getting urine in the sample. Once the sample is obtained, a portion of that sample is placed in the sample container. This is done with a small tongue depressor by spreading some sample on the occult blood reaction area or using the provided scoop device to place some feces into the preservative vials. As soon as the correct amount of sample is obtained, the remaining feces is dumped into the toilet and flushed. The contaminated collection bowl is placed in a trash bag and discarded in the trash. Verify that the sample is properly labeled when the patient returns the feces sample. Approximately 30 percent of the population Lhat abuses drugs is female, and most are of childbearing age. Mothers who are suspected of abusing drugs should be tested during pregnancy for drug use. Many of these patients have no prenatal care because they do not feel they can afford it or are afraid of their drug use being detected. Meconium or umbilical cord will document drug use over an extended period Copyright 2018 Cengage Learning. The procedure is used to obtain secretions from the upper respiratory tract by coughing up sputum into a sterile container. Materials: Gloves Hand disinfectant Container of warm water Waste container or waste sink Sterile sample container Label and requisition form Procedure: 1. Assemble equipment consisting of a sterile sample container, warm water in a glass, and a waste container. Instruct the patient to breathe deeply several times and cough up sputum and then expectorate the sputum into the container. The patient needs to place the lid tightly on the container and give it to the phlebotomist. Intestinal parasites and their eggs (ova and parasite [O & Pl) can be detected through feces examination. The containers may also be used for collection of feces for microbiology culture of feces. The microbiology department will check for enteric bacteria such as Salmonella, Shigella, or other pathogenic bacteria.

Phalangeal Fractures Phalangeal fractures in children commonly result from the stubbing of a toe or from direct injury medications 1-z order copegus paypal, such as a heavy object landing on the foot. The treatment of open phalangeal fractures is the same as that of any other open fracture. These injuries are fraught with complications such as nonunion, osteonecrosis, and refracture when surgical and nonsurgical treatment protocols are useddlfi Lawnmower Injuries Despite efforts to increase awareness of and provide education about lawnmower injuries, children remain at risk. It has been estimated that T1800 lawnmower-related injuries occur annually, approximately 9,300 of which occur in the pediatric population. Injuries involving riding lawnmowers have been noted to result in longer average hospital stays and have higher Injury Severity Scores than those involving other types of lawnmowers. Maintenance of the soft-tissue envelope and stabilization of associated fractures are key components of care. A large number of these injuries require multiple procedures and a multidisciplinary approach, El 2. Vacuum-assisted closure also has been demonstrated to be a useful adjunct and may result in a reduction in revision amputations as well as functional improvement. One study noted that prosthetic costs from the time of injury to age 13 years ranged from $53,140 to $116,040 per single extremity amputation. Considering the annual average cost of these injuries, the overall costs ranged from $43 to $75 million. Because of unique musculoskeletal anatomy, many of these injuries in children involve a growth plate, increasing the risk of long-term sequelae such as physeal arrest ity. In addition, the presence of a growth plate enhances remodeling potential in pediatric patients. Nonanatomic fracture reduction may lead to excellent clinical and functional outcomes in children. With appropriate treatment, most children and adolescents with musculoskeletal injuries of the lower extremity achieve excellent clinical and functional results. Key Study Points I the relative weakness of the physeal cartilage results in unique injury patterns in the skeletally immature population. The rate of growth arrest after physeal injury of the distal femur may be as high as 52%.

Observation over time can distinguish physiologic presentations from those that are patho- examination includes gait observation and assessment of total and segmental limb length and joint alignment, limb to evaluate coronal and sagittal alignment, including comparison views of the contralateral side, particularly in patients with a unilateral disorder. Conditions affecting the lower limbs can be congenital, developmental, or acquired. Treatments include observation with thorough parental education; bracing, casting, and surgical interventions, including guided growth; the acute or gradual correction of angular, rotational, or limb-length deformity; amputation; and prosthetic fitting. Although many rotational differences are physiologic, angular deformity more frequently can be pathologic. Understanding growth-related changes and age-appropriate differences is key to distinguishing these presentations. Rotational and angular Dr: Cruz or an immediate famiiy member serves as a boa rd member, owner; officer; or committee member of the Pedi- guided by the severity of the condition. Congenital tibial bowing can be self-resolving or can be indicative of the underlying abnormality of pseudarthrosis of the tibia. Foot differences seen at birth and throughout growth commonly can be managed with soft-tissue stretching or casting, but certain conditions require a more invasive approach. Miiewsiti or an immediate family member has received nonincome support such as equipment or services). Rotational Alignment the rotational profile of the lower limb evolves from birth to approximately age 10 years, after which little change is expected in lower limb rotational alignment. Anteversion of the femoral neck relative to the shaft of the femur is highest at birth, with a gradual decline to approximately known relationship exists between anteversion and the development of osteoarthritis of the hip or knee. The middle light line represents the mean value at a given point in time, and the other two light lines represent the deviation from the mean. Hosemont, resolve throughout growth, this symptomatic combination of excessive femoral anteversion and external tibial torsion is seen in older children and adolescents. The rotational profile should be considered when evaluating a patient with patellofemoral pain; in severe cases, miserable malalignment syndrome is treated with femoral and tibial derotational osteotomies. Because no effective nonsurgical treatment is available for physiologic rotational differences, observation accom- panied by thorough parental education and reassurance is the primary management strategy. Derotational osteotomy for persistent and symptomatic deformity can be performed using open, percutaneous, or intramedullary techniques.

The continued bleeding tendency should be treated after venipuncture by holding pressure on the site for at least 5 minutes medications post mi buy line copegus. After the 5 minutes, a 2-by-2-inch gauze pad should be folded down the middle and then folded down the middle again to make a thick 1-inch square. A nonlatex elastic wrap is then wrapped around the arm to provide additional continuous pressure to the site. After this is done, the patients nurse should be asked to check the arm in 15 minutes to check for any bleeding through the gauze. Do not allow an outpatient to leave until waiting 15 minutes to determine if the bleeding has stopped. Remind the outpatient with a purse to carry it with the opposite arm so the puncture site does not break loose and start bleeding again. A patient who immediately bleeds through the gauze square should have several layers of fresh gauze placed over the site and pressure held on the site until you are sure the bleeding has stopped. Once the bleeding has stopped, the arm must be wrapped with a nonlatex elastic bandage over several layers of gauze. Outpatients should be asked to wait in the waiting room for an additional 15 to 30 minutes until you are certain the bleeding does not return. Anticoagulant therapy also causes patients to develop hematomas from the venipuncture. This presents a problem for the next phlebotomist who has to draw blood from the patient and needs to avoid the hematoma. The only way to check this tendency is to treat each patient on anticoagulant therapy as if he or she has the tendency to continue bleeding. Apply pressure to the site for 5 minutes and then apply a gauze pressure dressing. A patient who is semiconscious or comatose is sometimes resistant and can be unaware of his or her actions. In this case the doctor must be notified so he or she can try to convince the patient that Helpful Hint the blood work is essential to the patients recovery. Often, by taking a little time and talking to With all patients, patients, you can convince them the testing is necessary, and you can overcome their resistance. Have the patients nurse present so it can equipment before be documented in the patients chart that the patient was held to draw the requested blood leaving the patient. Even an unconscious patient will often move Items sometimes get during a venipuncture. Gauze should be readily availsheets or fall to the able, and you should be ready to release the tourniquet if the patient moves and the needle floor. The concentrations of glucose, potassium, total protein, and calcium have been reported to be different. Except for glucose, the concentration of analytes is lower in skin puncture blood. When collecting sequential samples of glucose, potassium, total protein, or calcium, the phlebotomist should use the same collection method throughout the consecutive collections. This is most significant when a series of glucose tests is collected at timed intervals, as is done in a glucose tolerance test (see Chapter 9). Higher (H) or Lower (L) in Relationship to Venous Blood Analyte Glucose Total protein Calcium Potassium Order of Draw Helpful Hint If platelets aggregate while the phlebotomist is collecting the sample, the platelet count will be reduced significantly. If the platelets clump into groups of four platelets each, each clump would be counted as one platelet, not four. Therefore, the platelet count would be reported as only one-fourth of what it actually is. The body turns on its defenses to clot the blood at the puncture site and stop the bleeding as soon as the skin is punctured. As explained in Chapter 4, platelet aggregation occurs in the first step of the coagulation cascade. Any other additive samples are collected next, and clotted (serum) samples are last.

Reason/explanation for the step is the best method for infection control of both the patient and the phlebotomist.

Using the proper device will ensure proper blood the finger must be punctured the fingerprint lines. Scraping the finger with the collection tube will the amount of blood collected and possibly cause of the sample. After collection, have the patient hold gauze on the puncture site and mix the collection tubes times. Fill the collection tubes by touching only the of the collection tube to the drop of blood formed. Ensure the patient is not bleeding after the blood has been collected by applying a bandage if necessary Label the collection containers. Role-play with the child by showing with a stuffed animal or doll what will happen. Helpful Hint Offer parents a seat where they can sit and watch if they are not assisting with their child in the phlebotomy chair. A child will feel less threatened if your eyes are on the same level as his or her are. Avoid approaching the child with a needle or other device that is unfamiliar to the child. Carefully bring the need le out at the last moment to avoid prematurely alarming the child. There must be a careful balance between not letting the child see the needle and acting suspicious. Do not act as though you are hiding something because this will make the child more anxious. Tell them what you are going to do and continue to inform them of every step that you are taking. Younger children may not be able to talk, but they can understand much more than we often give them credit for. Usually the parent is there to hear what you are saying, and this reassures both the child and the parent that you know what you are doing. The phlebotomist is working to accommodate multiple individuals when a parent and child are involved. Special considerations must always be taken into account when performing pediatric phlebotomy. Before any procedure is started, the decision must be made about whether to perform a venipuncture, a heelstick, or a fingerstick. The decisio n depends on the age of the patient, the types of samples needed, and the ability of the child to hold still while the collection is obtained. Children are able to detect compassion and tenderness in your face and body language just as you are able to read the anxiety in theirs. A smile and a tone of voice that is reassuring go a long way in making the draw go better. Explain how differences in the age of a child can determine how he or she understands illness.

Radiographs medications enlarged prostate cheap copegus 200mg fast delivery, including posteroantcrior, lateral, oblique, and navicular views of the wrist, should be ordered but are sometimes inconclusive. Section 3: Upper Extremity Therefore, advanced imaging studies may be required to accurately diagnose a fracture. A recent meta-analysis demonstrated that all three modalities have sufficient capabilities to detect a fracture, with some suggestion that bone scintigraphy may be the most sensitive. A recent multicenter study compared 55 nondisplaced and minimally displaced scaphoid waist fractures treated nonsurgically in a short arm-thumb spica cast versus a short arm cast without thumb involvement. Historical reports have demonstrated that time to fracture union may be prolonged in nonsurgically treated patients, resulting in a trend toward surgical management, even for nondisplaced scaphoid waist fractures, secondary to time off from work and the morbidity of cast treatment of several months. Several surgical techniques have been described for surgical fixation of scaphoid waist fractures. Depending on the location of the fracture, either a volar or dorsal approach for surgical fixation may be undertaken. Proponents for the volar approach recommend extension of the wrist, reducing the humpback or flexion deformity of the scaphoid. For proximally based fractures, the dorsal approach offers the ability to capture the proximal fragment. Scaphoid nonunions represent one of the more difficult problems faced by hand surgeons. The two main areas that need to be addressed when treating scaphoid nonunions are correction of the associated humpback deformity and whether a vasculariaed or nonvasculariaed graft is warranted. In a recent systematic review, 23 studies compared corticocancellous grafting and cancellous grafting alone. In a 2013 case series, 12 patients with a scaphoid waist nonunion were treated at an average of 11 months after injury. Proximal pole nonunions with osteonecrosis remain a specific challenging subset of scaphoid nonunions. Several current treatments are available, including vasculariaed distal radius grafts. In a study of 21 wrists at an average follow-up of 40 months that underwent 1-2 intercompartmental supraretinacular artery pedicle grafting for proximal pole scaphoid nonunions, the union rate at 14 weeks was 36% and there was improvement in Mayo wrist scores, but range of motion and grip strength did not improve. No surgical complications were noted in the study and all three patients went on to achieve union. An innovative approach to the management of unsalvageable scaphoid proximal pole union times-11 weeks versus 16 weeks. The hamate autograft replaced the proximal pole of the scaphoid and the capitohamate ligament was used to repair to the native scapholunate ligament.

In a case series, 16 patients underwent proximal scaphoicl arthroplastjr with a free medial femoral condyle trochlea graftfij Union was achieved in 15 of 16 patients, with 1 requiring a salvage procedure. The indications for vascularixed osteochondral grafts have expanded to Innate reconstruction in Kienbtick disease, capitate resurfacing, radiocapitellar resurfacing, and talus resurfacing. However, distal femoral complications, including femur fractures, have been described and further research is needed regarding long-term outcomes and donor site morbidity. Standard wrist radiographs should be evaluated and Gilula lines should be scrutinized. When classifying perilunate injuries, two distinct variants, termed greater arc and lesser arc injuries, refer to injuries associated with carpal fractures or isolated ligamentous injuries, respectively. In a case series of 27 patients who had either adjunct arthroscopjr or complete arthroscopic repair, patients had 58% of wrist motion and T151: of grip strength when compared to the contralateral side. Injury occurs secondary to the minimal bony restraint of the joint and the associated motion that is inherent at each joint. The mechanism of injury is often an axial load occurring while the fist is clenched, whereby the metacarpal is flexed and directing a dorsal force that causes dislocation. When the injury is secondary to high energy or there is evidence of a significant articular step-off, open reduction and stabilization of the joint surface may be required. Range of motion and fifth metacarpal height remain unchanged, with an average union time of 6 weeks. Fractures are often classified based on the location of the fracture on the metacarpal [base, shaft, or neck. Given the stout soft-tissue attachments about the metacarpal, most metacarpal shaft injuries can be treated nonsurgically. However, border digits and those with substantial shortening or rotation may require surgical fixation. Current methods of fixation vary and range from K-wire fixation to intramedullary nailing or plate fixation. Each construct offers separate benefits and risks, which must be considered before use. It was concluded that unicortical 3: Upper Extremity fixation provides enough support to allow early range of motion. The benefit of internal fixation includes early range of motion and less risk of pin tract infections. However, this benefit may be counterbalanced by the surgical scar and risk for tendon adhesions or need for future plate removal. A recent study has demonstrated that secondary to the short nature of the metacarpal and the relative instability of the fifth digit border digit), these reductions often fail to maintain adequate alignment. Patients demonstrated an immediate difference in angulation after reduction but at final follow-up there was no difference in metacarpal neck angulation. Phalangeal Fracture-Dislocations Phalangeal fractures have an annual incidence of 12. The preferred method depends on the patient, location of the fracture, compliance, and surgeon familiarity. For phalangeal fractures, screws demonstrated quicker return of motion with fewer complications. When comparing screw to plate constructs, grip strength comparison between constructs demonstrated no statistical difference at early (1 month) and late follow-up. Given the location of the tendons and vital structures about the finger, midaxial approaches may be used to avoid tendon adhesions and complications. Care should be taken to prescribe the correct splint that immobiliaes only those joints necessary to protect the fracture. For articular base fractures including the volar lip of the phalanx, the lateral view is often the most important because it allows for good interobserver reliability to determine whether surgery is recommended. However, they were unable to come to a consensus on which surgical technique should be used. Extension block pinning with K-wires offers a relatively simple way to help stabilise those fractures, which reduce with flexion. Care must be taken to ensure that the phalanx is not hinging where the volar fragment is missing, as previously mentioned, as this may diminish final joint motion. Ten patients undergoing dynamic external fixation in patients who had sustained a proximal interphalangeal joint fracture-dislocation at an average of 2 The largest benefit of dynamic external fixators is the ability to maintain condylar reduction while allowing some motion at the joint surface. When the fracture cannot be directly repaired and the finger is unstable, several salvage procedures have been described, including hemihamate reconstruction, volar plate arthroplasty, and interphalangeal joint fusion. Each procedure has its own indications and merits and provides results that vary based on patient expectations and needs. A computer-driven simulation was performed measuring the dorsal subluxation and translation. Injury to the nail bed is common and it is important to determine if the germinal and sterile matrix have been violated and whether the nail plate is viable"! Section 3: Upper Extremity A bony mallet finger results when the terminal tendon avulses a portion of the articular surface of the base of the distal phalanx.

Neurologic sequelae such as cauda equina syndrome, paralysis, or cognitive dysfunction attributable to meningitis can result, adding a sense of urgency to the diagnosis and treatment. Irrespective of the specific characteristics of the infection, successful treatment involves an accurate diagnosis treatment, and surgery in some circumstances. The Spine infections are a difficult problem that can be a dreaded postoperative complication or present as discitis and osteomyelitis in the absence of previous surgery. Antibiotics are always an important aspect of successful treatment, vvhether or not surgery is deemed necessary. Establishing the causative organism is of great importance in guiding antibiotic choice and duration, over broad-spectrum antibiotics because of optimal efficacy and decreased risk to the patient. Advances have been made in diagnostic testing, in understanding and mitigating the risk factors for developing postoperative infection, and in minimally invasive surgical treatment options. Patient Presentation, Risk Factors, and Causative Organisms because species-specific antibiotics are much preferred and species determination, appropriate antimicrobial the maintenance or restoration of spinal alignment and stability, and the preservation of neurologic function. An understanding of general patient demographics and diagnosis and treatment considerations for vertebral discitis and osteomyelitis in the adult and pediatric populations, epidural abscesses, and postoperative surgical site infections is important. Recent develop- treatment goals are pain relief, infection eradication, ments include new diagnostic tools, the evolving role of negative-pressure vvound dressings, a better understanding of the risk factors for surgical site infection, related strategies to reduce postoperative infections, and emerging minimally invasive surgical techniques. Keywords: spine infections: discitis: vertebral cistevamyelitis:r epidural abscess; tuberculous spondylitis infection and is reliably present. Systemic manifestations may include fever, malaise, weight loss, an altered mental status in the elderly, and irritability in infants. Risk factors include smoking, obesity, malnutrition, diabetes, and immunodeficiency. Local radiation and malignancy predispose the patient to infection throughout the musculoskeletal system, including the spine. Infections in other areas of the body, such as the urinary tract, heart, or extremities, can lead to bacteremia and subsequently as transcolonic gunshot wounds, also can lead to spine infection. Other organisms include Staphyiococcus epidermidis, Streptococcus species, and Escherichia coii.

Laboratory Studies Irrespective of the infecting organism or patient factors, the initial diagnostic algorithm is consistent and typically consists of laboratory tests, imaging studies, and the acquisition of tissue for organism identification. These tests are nonspecific and indicate a systemic immune response, and are used to monitor the response to treatment. E Inflammation in and about the vertebral bodies causes bone marrow changes that appear as low intensity on T1-weighted images and as high signal intensity on T2-weighted images. Similar findings can be seen in lytic metastatic disease, except that metastatic disease does not involve the disk, whereas spine infections other than tuberculosis characteristically do involve the disk. Gallium and technetium scans, especially when used in combination, are highly sensitive and specific and are excellent at localizing the site of infection. The entire skeleton can be imaged, revealing other areas of osteomyelitis such as the extremities or noncontiguous regions of the spine. Radiolabeled leukocyte imaging is specific but plagued by low sensitivity in patients with spine infection. Biopsy Biopsy is indicated in all cases except in patients with positive blood cultures. Biopsy affords the best chance of isolating an organism so that treatment can be modified based on culture and sensitivity results. The use of large-bore needles such as the Craig needle biopsy apparatus should be encouraged to obtain relatively large amounts of solid tissue from the specific site of interest. The culture yield may be improved by holding the specimen for 10 days, but this step is not routine at most institutions and often must be specified in the laboratory orders. Organisms of low virulence such as skin flora are examples of slow-growing species that can be missed if the microbiology laboratory holds the specimen for fewer than 10 days. If the organism is identified through blood cultures, antibiotic treatment can begin immediately, and biopsy is avoided. Fastidious organisms such as M tuberculosis are difficult to culture, often taking 6 weeks or more to speciate. Bony changes detectable using conventional radiography usually lag symptom onset by 10 days or more, so plain radiographs may be normal. Disk space narrowing, blurring of the vertebral end plates, and soft-tissue swelling are the first radiographic signs, except with tuberculosis, which often spares the disk space early in the disease. Later findings include disk space collapse, vertebral body destruction or patchy sclerosis, and spinal deformity. American Academy of Drthopaedic Surgeons Chapter 49: Spine Infections cultures should he considered, although this measure should be undertaken in consultation with an infectious disease specialist. Because these technologies are not universally available, their role is still being defined. People with diabetes, intravenous drug abusers, and immunocompromised hosts in particular are predisposed to infection. Urinary tract infections and the transient bacteremia seen following genitourinary procedures are common sources, although any remote-site infection can result in bacterial seeding. Hematogenous vertebral osteomyelitis is thought to originate in the vertebral body because the intervertebral disk is a relatively avascular than acute infections. Neurologic impairment is present in a small number of cases and is usually a result of neural element compression from an epidural component of the infection or bony collapse. If blood cultures are negative, obtaining a biopsy is of paramount importance in guiding antimicrobial therapy. The bacterial infection spreads from the verte- Treatment Antibiotics are the mainstay of successful treatment. Antibiotic duration and route of administration are based more on opinion than on science because controlled studies are lacking. Accordingly, the most common standard is at least 6 weeks of intravenous antibiotics. This bral end plate to the adjacent disk space, which is a potent bacterial breeding ground because of its avascularity. The disk therefore bears the brunt of the infection early in the infections course, even though the infection starts in the vertebral body. Because of the anatomy of the blood supply to the vertebral column, isolated discitis in adults is considered to be very rare. In general, adult pyogenic vertebral osteomyelitis and discitis should be considered coexisting entities and may be referred to as discitisfosteomyelitis. Microbiology 3 nurses is the most common causative organism, responsible for approximately one-half of all cases. Gram-negative organisms such as E coii and Pseudomonas sernginosc are less common and seem to be associated with genitourinary infections and procedures as well as intravenous drug use. Organisms of low virulence, such be difficult to know whether they are contaminants or causative organisms. The choice of antibiotic ideally is tailored to the susceptibilities determined from the positive cultures, but if an organism is not identified, broad-spectrum coverage may be necessary. Some concern exists that cephalosporins do not penetrate the disk at serum levels, whereas positively charged antibiotics such as vancomycin, gentamicin, and clindamycin do penetrate the disk at serum levels. These laboratory tests should be repeated after antimicrobial therapy has been discontinued for some time. It is fairly typical to check laboratory studies every 2 weeks after the cessation of antibiotics for a period of 6 to 3 weeks to make sure no residual infection radiographically after the cessation of therapy. If relapse occurs, it is reasonable to attempt a second course of intravenous antibiotics followed by an oral regimen along vided the infection is otherwise amenable to nonsurgical treatment.

More accurate for neonates than a total bilirubin symptoms yeast infection women 200 mg copegus mastercard, which is appropriate for adults and children more than 15 days old. Newborn Screen As required by most state laws, newborns are screened for genetic disorders such as phenylketonuria, galactosemia, hypothyroidism, homocystinuria, maple sugar urine disease, and sickle cell anemia. The method detects blood produced from gastrointestinal lesions caused by many factors, including ulcers and colorectal cancer. Osmolality Osmolality (number of dissolved molecules) of serum causes the pituitary gland to secrete, which in turn causes the kidneys to retain more or less water. Ova and Parasites (O & P) Combination of three methods of wet moun t and stains used to detect and identify intestinal parasites or the eggs of the parasite. The usual sample is feces; however, parasites or eggs can also be found in sputum, urine, blood, or tissue. Phenobarbital Level Anticonvulsant drug used especially in the treatment of epilepsy. Pinworm Exam: Scotch Tape Prep Clear cellophane tape is pressed against the peritoneal region. Any pinworm eggs that are present stick to the tape and are detected when the prep is examined microscopically. Decreased potassium is the result of any disease process that causes diarrhea or severe vomiting. Periodic monitoring of its amount in the blood is done to determine the dose to be given. Protein Electrophoresis Total protein level in serum, urine, or spinal fluid is quantitated, and then the proteins are separated into five distinct fractions based on their movement in an electrical field. The test finds its widest use in monitoring the administration of Coumadin (warfarin) therapy. Coumadin is a delayed-acting oral anticoagulant that acts to rapidly decrease all the vitamin K-dependent factors. Protime may be abnormal when there is decreased vitamin Kin a poor diet, in severe liver disease, or in some severe clotting factor deficiencies. Blood levels too low may be ineffective; levels too high may lead to harmful side effects. Low levels may reflect hypoglycemia; high levels may reflect a diabetic condition. Hematocrit the hematocrit is the percentage of red blood cells compared with the amount of plasma in whole blood. A decrease in the hematocrit value can be indicative of destruction of red blood cells, interference in the production of red blood cells, or overhydration. An increase in hematocrit is the result of an increase in red blood cell production or dehydration. The primary purpose of hemoglobin is to carry oxygen from the lungs to the cells and to carry carbon dioxide from the cells to the lungs. Appearance of the antibody signifies a convalescent state and recovery from the acute phase of the disease. Also indicates prior exposure to the virus through vaccination, or indicates passive acquisition for administration of hyperimmune serum. India Ink Prep Stain used mainly on spinal fluid to detect the capsule on the yeast Cryptococcus neoformans. Called a negative stain because the capsule of the yeast appears as a halo against the dark background of ink. These isoenzymes may be separated according to their differing mobilities in an electrical field. Increased lipase levels indicate pancreatic damage by pancreatitis and pancreatic cancer. The purpose of the lipid panel is to detect disorders of lipid metabolism and to assess the risk of heart disease. Abnormal red and white cell morphology, as well as a platelet estimate, are also recorded. Periodic monitoring of its amount in the blood is made to determine the dose to be given. Blood levels too low may be ineffective, and blood levels too high may lead Lo harmful side e! Dilantin (Pheny toin) Level Anticonvulsant drug used especially in the treatment of epilepsy. Blood levels too low may be ineffective, and those levels too high may lead to harmful side effects. The relationship among these electrolytes is maintained in careful balance by the function of the kidneys, lungs, and endocrine glands. The presence of heterophil antibodies is highly diagnostic of infectious mononucleosis. Anemic conditions associated with increased ferritin levels are megaloblastic and hemolytic anemia. Iron storage disorders such as hemochromatosis and hemosiderosis cause high ferritin levels. Decreased ferritin levels can be seen in iron-deficiency anemia, severe protein deficiency, and patients undergoing hemodialysis. Fibrinogen Fibrinogen is manufactured in the liver and is used for the production of fibrin. Increased fibrinogen is associated wiLh diseases such as hepatitis, multiple myeloma, cancer, rheumatic fever, tuberculosis, and septicemia. This syndrome causes a depletion or decrease of fibrinogen and other clotting factors by overstimulating the coagulation process. High levels of gastrin can be supportive of a pancreatic tumor, gastric cancer, or pernicious anemia. Gentamicin Level: Predose (Trough); Gentamicin Level: Postdose (Peak) these tests determine the concentration of the antibiotic gentamicin in various body fluids (usually blood) at a specific time. A blood sample collected 5 minutes before the antibiotic is given is called the predose sample, and the sample collected 30 - 60 minutes after infusion of the antibiotic is called the postdose sample. If either sample has a large concentration of the antibiotic, it may be toxic to the patient. A low concentration of the antibiotic may be inadequate to suppress the growth of the bacteria. If a cord blood sample is unavailable or unsatisfactory, a heelstick sample may be used. Cortisol Principal corticosteroid hormone secreted by the heart muscle that rises when there is heart damage. Levels of this hormone in blood or urine are used for the evaluation of adrenal or pituitary dysfunction. Certain viral diseases, such as infectious mononucleosis, cytomegalic inclusion disease, influenza A and B, parainfluenza, autoimmune disease, and autoimmune hemolytic anemia, cause an elevation of cold agglutinins. Creatine Kinase (Ck Total) Enzyme of the heart that is increased following a myocardial infarction. Total creatine kinase is made up of three distinct fractions referred to as isoenzymes. Creatinine Metabolic waste product of muscle tissue that is eliminated from the body via the kidneys. Individual increases and decreases in the parameters provide the physician with invaluable information relating to the diagnosis and prognosis of a disease. Comprehensive Metabolic Panel Consists of glucose, certain type of acid-fast bacteria that may be living in the patient and causing an infection. Coombs, Direct (Antiglobulin, Direct) Determines two small bottles containing sterile media. Identification of the bacteria may help determine cause of fever and chills or other patient symptoms. One of the two bottles collected is an anaerobic bottle for bacteria that cannot grow in the presence of oxygen. An aerobic bottle is also collected for those organisms that require oxygen to grow. With these antibiotics neutralized, bacteria inhibited by the antibiotics are able to grow.

He is on subcutaneous unfractionated heparin for prevention of deep venous thrombosis. He is otherwise recovering well with no complications, and a lower extremity Doppler is performed, which is negative for deep venous thrombosis. Which of the following additional tests would be most helpful in determining the cause of his thrombocytopenia A 37-year-old female with a history of deep venous thrombosis during her first pregnancy and two spontaneous abortions is evaluated in the emergency department.

He reports pain in both legs with standing and walking but improvement in the pain and edema with elevation of the legs. He has 3+ pitting edema of the bilateral lower extremities with normal warmth, mild tenderness and numerous varicose veins. Inspection of the skin reveals a reddish-brown hyperpigmented and indurated dermatitis involving the anterior lower legs bilaterally. The patient reports the pain started 3 hours ago, is very severe, and is periumbilical. Physical examination is remarkable for an irregularly irregular heart rhythm and mild abdominal distension. Five hours after arrival his condition deteriorates, his abdomen becomes grossly distended, his bowel sounds become inaudible, and he dies. A 55-year-old male with well-controlled type 2 diabetes mellitus, hypertension, and paroxysmal atrial fibrillation presents with acute onset of right flank pain with hematuria. On examination he appears to be in moderate pain, his lungs are clear, he has an irregularly irregular rhythm, and his right flank is tender to palpation. A 32-year-old woman has routine lab work done as part of her annual physical examination. She returns to the clinic 3 days after her blood draw complaining of pain in the left antecubital fossa. On examination there is mild erythema without induration, no palpable fluctuence, and the basilic vein is tender and palpated as a nodular "cord. The tissue has preservation of normal architecture; however, there is loss of nuclear and cytoplasmic basophilia. Associated with these changes are abundant extravasated red blood cells in the tissue. Thrombus in the right main pulmonary artery Cardiovascular, female reproductive 25. A 67-year-old woman has a central venous catheter placed during hospitalization for dehydration. The catheter is placed using guidewire technique and ultrasound guidance, and the tip of the catheter is demonstrated to be in good position in the superior vena cava. On the third hospital day the nurse finds the patient sitting up in bed with the venous catheter partially dislodged. The nurse removes the catheter and holds pressure; however, the patient rapidly becomes tachycardic and hypoxic. A 63-year-old male undergoes left heart catheterization in preparation for possible aortic valve replacement to treat severe aortic regurgitation. The procedure revealed extensive calcification in the thoracic aorta and moderate nonobstructive coronary artery disease. A week after the procedure he presents to his primary care physician complaining that his left big toe has turned blue. In addition to a patchy cyanosis of several toes on both feet, he is noted to have livedo reticularis of the lower extremities and elevation of the serum creatinine. A 57-year-old man is evaluated in the emergency room for sudden onset of left hemiparesis, which began 45 minutes prior to his arrival.

Which of the following physiologic effects would not be expected from Vasopressin A 37-year-old female with a history of deep venous thrombosis during her first pregnancy and two spontaneous abortions is being evaluated in the emergency department. Forty minutes prior to arrival she experienced the sudden onset of weakness of the right face, right arm, and right leg. Neurologic examination reveals flaccid paralysis of the right side of the body with expressive aphasia without visual field defect. Correct: Fibrotic and thickened alveolar septal capillaries (B) With congestive heart failure, a chronic process, causing multiple episodes of pulmonary edema, chronic pulmonary congestion, characterized by fibrotic and thick alveolar septa and macrophages with hemosiderin would be most characteristic of the clinical scenario (B). For the most recent episode, dilated alveolar septal capillaries filled with red blood cells would be appropriate; however, it would not best describe the overall clinical scenario. Correct: Increased hydrostatic pressure (A) the fluid in the pleural cavities represents pulmonary edema due to heart failure from the uncontrolled hypertension. Although the other mechanisms listed can lead to pulmonary edema, the most likely cause, given the scenario, would be congestive heart failure. Congestive heart failure will increase hydrostatic pressure in the pulmonary vasculature, causing fluid to leak into the surrounding space (A). In congestive heart failure, a common histologic finding is heart-failure cells, which are macrophages filled with hemosiderin that are found in the alveolar airspaces (B). Correct: History of recent surgery (E) this patient has sustained a deep venous thrombosis. Unilateral edema of a lower extremity could be due to venous or lymphatic obstruction. A neoplasm would be a rare cause for unilateral swelling of a lower extremity (D). Of the choices, only the history of recent surgery would be expected to reveal a potential cause for this deep venous thrombosis (E). All of these findings can also be seen in acute pulmonary embolism; however, the finding of an infiltrate on the chest radiograph is consistent with pneumonia and would not be expected in acute pulmonary embolism (A). Correct: Cardiogenic shock (C) the patient has all the signs and symptoms of cardiogenic shock (C). The red discoloration of the skin is a sign of acute inflammation due to the mosquito bite and occurs due to dilation of blood vessels, an active process.
