If the potassium level is found to be low during attacks order ginette-35 2 mg mastercard, secondary causes of hypokalemia (diuretics purchase 2mg ginette-35 amex, hyperaldosteronism cheap ginette-35 2 mg on line, laxatives generic 2mg ginette-35 visa, etc discount ginette-35 2 mg free shipping. A serum potassium level that is elevated without apparent cause is suggestive of hyperkalemic periodic paralysis. A 25-year-old woman presents for evaluation of progressive muscle weakness and fatigability for the past 9 months. She has otherwise been healthy and takes no medication except oral contraceptives. The weakness is worse toward the end of the day and after repetitive activity. On examination, bilateral pto- sis and extraocular muscle weakness are noted, particularly on upward and lateral gaze. Attempts at forced smiling produce a snarling expression. Moderate weakness is evident on upper-extremity muscle testing. Deep tendon reflexes and plantar reflexes are normal. Routine laboratory examinations, including CBC, chemistry panel, and thyroid function testing, are normal. What is the most likely cause of this patient’s symptoms? Polymyositis Key Concept/Objective: To be able to diagnose myasthenia gravis and to distinguish it from other myasthenic and myopathic syndromes Primary care physicians should suspect myasthenia gravis in patients who have progres- sive skeletal muscle weakness and fatigability. The illness typically presents in young women or older men as weakness of the eyelids and extraocular muscles, which leads to ptosis and diplopia. Patients develop weakness of the neck extensors and bulbar weakness that leads to dysarthria and dysphagia. Proximal weakness may present as progressive weakness experienced when climbing stairs or rising from a chair. Some patients complain of weakness combing their hair. Fluctuation of symptoms and fatigue with activity are characteristic. Deep tendon reflexes and the plantar reflex are normal. The presence of antibodies against the acetylcholine receptor and a positive EMG are diagnostic. Lambert- Eaton myasthenic syndrome is frequently associated with small cell lung cancer; its symp- toms are ptosis, diplopia, fatigability, and muscle weakness. Features distinguishing it from myasthenia gravis include hyporeflexia, autonomic dysfunction, and an increase in mus- 10 BOARD REVIEW cle strength after several seconds of maximal effort. Congenital myasthenia presents in infancy, childhood, or, occasionally, young adulthood. Motor neuron disease can present as muscle aches, weakness, and fatigue. The first manifestation may be asymmetrical dis- tal weakness, with progressive wasting and atrophy of muscles or difficulty with chewing, swallowing, and moving the face and tongue. Fasciculation, caused by spontaneous twitching of motor units, is characteristic. With prominent corticospinal involvement, hyperactivity of the deep tendon reflexes is found. A 72-year-old man presents to the emergency department for evaluation. He is accompanied by his wife, who provides a history of his present illness. The patient was in his usual state of health until 1 hour ago, when he lost the use of his right arm and leg after sliding out of his chair. He is being treated for hypertension, diabetes, and dyslipidemia, all of which have been under moderately good control for many years. On physical examination, the patient has a dense paresis of his right upper and lower extremities.

Trimethoprim-sulfamethoxazole daily for 3 to 6 months D ginette-35 2 mg otc. Key Concept/Objective: To understand the spectrum of infection in the posttransplantation period Because of immunosuppressive therapy order 2 mg ginette-35 with amex, patients who receive transplants are at risk for acquiring a variety of infections order ginette-35 2mg. Infectious agents vary relative to the time of trans- plantation purchase ginette-35 2 mg otc. The first month after transplantation is characterized by infections that are related to the hospitalization purchase ginette-35 2 mg on line. In this period, urinary tract infections, bacteremia caused by gram-positive cocci, and hospital-acquired pneumonias are common. After the first month and up to 6 months after transplantation, the most common infections are relat- ed to immunosuppressive therapy. Opportunistic infections such as CMV, EBV, Pneumocystis carinii infection, and diverse fungal infections predominate. After 6 months, when immunosuppressive therapy is less intense, common infections become prevalent; these include community-acquired pneumonia and cellulitis. CMV is one of the most important posttransplantation infections; it can present as a systemic viral ill- ness, pneumonia, or gastrointestinal disease. Patients can develop primary infection as a result of receiving an organ from a seropositive donor or through reactivation of latent virus. It has been shown that prophylactic oral ganciclovir therapy, started at the time of transplantation and continued for 12 weeks, decreases the incidence and sever- ity of CMV disease. A 47-year-old man who recently received a renal transplant and was started on steroids, cyclosporine, and mycophenolate mofetil presents for routine follow-up. On physical examination, his blood pressure is noted to be 189/96 mm Hg. Which of the following statements regarding hypertension and renal transplantation is true? Hypertension is a rare posttransplantation complication B. Mycophenolate mofetil can cause vasoconstriction and worsen hypertension C. Graft dysfunction causes worsening of hypotension D. Cyclosporine commonly induces a volume-dependent form of hypertension Key Concept/Objective: To understand the relationship between immunosuppressive medica- tions and hypertension 30 BOARD REVIEW With the goal of graft survival in mind, the long-term follow-up of patients undergoing renal transplantation should focus on management of the major causes of morbidity and mortality. Cardiovascular disease, specifically hypertension, is one of the most common posttransplantation complications, affecting 80% to 90% of these patients. The etiology of hypertension in this population is multifactorial but includes diseased native kidneys, use of immunosuppressive medications, graft dysfunction, and, rarely, transplant renal artery stenosis. Although calcineurin inhibitors are the cornerstones of immunosuppression, as a class, these agents commonly cause hypertension. Specifical- ly, cyclosporine causes direct vasoconstriction and induces preglomerular vasoconstric- tion, resulting in a volume-dependent form of high blood pressure. Other classes of immunosuppressants that cause hypertension are corticosteroids and TOR (target of rapamycin) inhibitors. Antimetabolites, however, such as azathioprine and mycophe- nolate mofetil, are important in immunosuppressive agents because of their lack of nephrotoxicity and because they have little effect on blood pressure. A 43-year-old woman with end-stage renal disease (ESRD) presents to your clinic for renal transplant evaluation. She has focal segmental glomerular sclerosis and has been doing well for some time on hemodialysis, but she is concerned about "losing the transplanted kidney" because of her original disease. Which of the following statements regarding recurrence and graft loss associated with her primary renal disease is false? Primary glomerular diseases frequently recur and are commonly associated with graft loss B. Lupus nephritis rarely recurs after transplantation C.

Most patients experience some degree of joint stiffness ginette-35 2 mg fast delivery, especially in the morning after awakening ginette-35 2 mg with mastercard, which may accompa- ny or precede joint swelling or pain buy 2mg ginette-35 free shipping. These symptoms are hallmarks of disease activity and help distinguish RA from noninflammatory diseases such as osteoarthritis generic ginette-35 2 mg visa. However buy ginette-35 2 mg low price, joint stiffness and swelling are not specific for RA and can occur with other types of inflamma- tory arthritis. When RA is progressive and unremitting, nearly every peripheral joint may eventually be affected, although the thoracic, lumbar, and sacral spine are usually spared. A 48-year-old female patient of yours with moderately severe RA presents for a scheduled visit. She is very satisfied with her current therapy and feels that joint pains, swelling, and stiffness have all improved over the past 3 months. Her energy level has also improved, and she has recently planted a large flower garden. Her only complaint today is that she can’t “catch her breath” when she works in her garden. Her shortness of breath is worsened by exertion, and she now states that she experiences shortness of breath while ambulating in her house. Over the past week, she has developed pain in her right chest; the pain worsens with exertion or with deep inspiration. Physical examination is noteworthy for decreased breath sounds, decreased fremitus, dullness to percussion, and a pleural rub of the right basilar lung field. Chest radiography confirms the diagnosis of rheumatoid lung disease. Which of the following statements regarding rheumatoid lung disease is true? The most common form of lung involvement is pleurisy with effusions B. Rheumatoid effusions typically have a glucose concentration of greater than 50 mg/dl C. RA is not a reported cause of cavitary lung disease D. Rheumatoid lung disease with fibrosis typically causes an obstructive ventilatory defect with a decreased carbon dioxide diffusion rate Key Concept/Objective: To know the key features of rheumatoid lung disease The most common form of lung involvement in RA is pleurisy with effusions. Evidence of pleuritis is often found at postmortem examination, but symptomatic pleurisy occurs in fewer than 10% of patients. Clinical features include gradual onset and variable degrees of pain and dyspnea. The effusions generally have protein concentrations greater than 3 to 4 g/dl, as well as glucose concentrations lower than 30 mg/dl; the latter finding has been ascribed to a primary defect in glucose transport. Rheumatoid nodules occur in the pul- monary parenchyma and on the pleural surface. They range in size from just detectable to several centimeters in diameter. Such nodules can be difficult to distinguish radiologically from tuberculous or malig- nant lesions and often require further evaluation, including biopsy. Progressive, sympto- matic interstitial pulmonary fibrosis that produces coughing and dyspnea in conjunction with radiographic changes of a diffuse reticular pattern (i. The lesion is histologically indistinguish- able from idiopathic pulmonary fibrosis. Chest radiographs show pleural thickening, nod- ules, diffuse or patchy infiltrates, and a restrictive ventilatory defect that is characterized by a decreased carbon dioxide diffusion rate. The patient has been receiving a cyclooxygenase-2 (COX-2) selective NSAID for RA, with only minimal improvement in her symptoms. She continues to have significant pain and morning stiffness in her hands and wrist. She has been reading about the many available therapies for RA and feels that she now needs additional therapy.
