Chemical Burns—The severity of a chemical burn (c) Steroids is determined by the concentration, duration of 2.

Findings on physical examination may be deceptively normal, but tachycardia is a consistent finding. Pleuritic chest pain and hemoptysis suggest a peripheral embolism adjacent to the pleura. Myocardial infarction is a rare complication in pregnancy and likely to present with chest pain, and primary pulmonary hypertension while common in young woman would present with the insidious onset of dyspnea on exertion. The eye findings in Wernicke encephalopathy include bilateral (but not necessarily symmetrical) abductor weakness or paralysis, horizontal diplopia, strabismus, and nystagmus. There is no indication to administer phenytoin for this patient, and while diazepam maybe important for prophylaxis against alcohol withdrawal symptoms, the most important immediate treatment is thiamine. The inhibition of osteoclast-mediated bone resorption and the stimulation of renal calcium clearance are mediated by receptors on osteoclasts and renal tubular cells. The diagnosis is made with 2 major, or 1 major and 2 minor criteria, and evidence of group A streptococcal infection (positive throat culture or rapid streptococcal antigen test, or rising antibody titers). In the United States, it is estimated that only 2000 potential donor hearts become available each year for 20,000 potential recipients. The optimal candidates will have a high likelihood of return to a high level of function, to be mentally vigorous and medically compliant. Common reasons for treatment include hemolytic anemia, cytopenias, disfiguring lym-phadenopathy, symptomatic organomegaly, or systemic symptoms. Chlorambucil is easy to administer, but fludarabine is considerably more effective. Patients with cirrhosis and portal hypertension are at risk for variceal bleeding. Narcotics and sedatives are also frequently implicated as precipitants for hepatic encephalopathy. It most commonly affects older children and young adults, and is more common in Blacks than in Whites. About 20%–50% of patients develop end-stage renal disease within 20 years of diagnosis. Other causes of asymptomatic hematuria, with or without proteinuria, include sickle cell disease, Alport syndrome, resolving glomerulonephritis, and thin basement disease. Chronic bronchitis is characterized by milder dyspnea, greater sputum production, more frequent hypercarbia and polycythemia, and more evidence of cor pulmonale and pulmonary hypertension. There is not usually a vasculitis present, although a mononuclear infiltrate may be present. Impairment of proprioceptive fibers can lead to gait abnormalities and Charcot joints. Common syndromes include wrist or foot drop and third, fourth, or sixth cranial nerve palsies. Autonomic neuropathy may cause gastroesophageal dysfunction, bladder dysfunction, and orthostatic hypotension. Randomized controlled trials in Type 1 and 2 diabetes demonstrate that good glycemic control results in lower microvascular complications such as retinopathy or neuropathy. Allopurinol is started only when all inflammation is gone and colchicine prophylaxis has been started. Emboli can originate from an arterial atheroma (eg, common carotid bifurcation) or from the heart. On occasion, emboli occur without obvious source (eg, hypercoagulable states, malignancy, ecclampsia). The acute nephritic syndrome consists of the abrupt onset of hematuria and proteinuria, often accompanied by azotemia and renal salt and water retention. Only a minority of patients with dyspepsia are found to have an ulcer on endoscopy. Symptoms of intravascular hemolysis include flushing, pain at the infusion site, chest or back pain, restlessness, anxiety, nausea, and diarrhea. In comatose patients, hemoglobulinuria or bleeding from disseminated intravascular coagulation can be the first sign. Hyperthyroidism is hardest to control in the first trimester and easiest in the third trimester. Orthostasis is probably the most common serious side effect and is difficult to manage. The most common pathogenic mechanism is thought to be excessive or redundant mitral leaflet tissue, with the posterior leaflet more commonly involved. Over 95% of children achieve remission within 8 weeks of institution of prednisone therapy. Therefore, in children with nephrotic syndrome, empiric therapy is frequently employed, rather than initial renal biopsy. Five-year cure rates in such lesions approach 60%, but second primaries are common (5% per patient per year). There is no evidence that screening programs based on sputum examination will decrease mortality. Pulsus paradoxus is uncommon in constrictive pericarditis and rare in restrictive cardiomyopathy. The use of cyclosporine has improved 1-year cadaveric survival rates to the 80%–85% range. Side effects include hepatotoxicity, hirsutism, tremor, and gingival hyperplasia, but only the nephrotoxicity presents a serious management problem. There is usually a history of at least 2 episodes of neurologic deficit at more than one site. Other common presenting symptoms include weakness, sensory loss, and paresthesias. The prognosis is generally good, although relapses can occur before the final remission. Estrogen therapy may retard demineralization of the skeleton and may also reduce blood and urinary calcium levels. There is no clear consensus on when asymptomatic hyperparathyroidism requires surgery. Female heterozygotes have a dual population of red cells and, depending on the proportion, may develop symptoms. During hemolysis, older red cells with the lowest enzyme levels are destroyed, and diagnostic tests done at this time may be falsely normal. Other commonly used drugs for community-acquired pneumonia are high-dose amoxicillin, cefuroxime, trimethoprim-sulfamethoxazole, and doxycycline. Theoretically, empiric therapy should be guided by knowledge of local resistance patterns. Categories of tubulointerstitial kidney disease include toxins (exogenous and metabolic), neoplasia, immune diseases, vascular disorders, infections, and hereditary renal diseases. Defects in urinary acidification and concentrating ability are frequently the most troublesome manifestations of tubulointerstitial kidney disease. Antacids, sucralfate, and H2-blockers are all useful in less severe reflux disease. If vasculitis occurs, purpura, urticaria, skin ulcers, and mononeuropathy are its most common manifestations. Generally, however, crystalloid or colloid solutions are sufficient for volume replacement until properly matched blood is available. Severe disease can cause pulmonary congestion (Kerley B lines) and enlargement of the right ventricle, right atrium, and superior vena cava. Women are more frequently affected than men (3:2 ratio), and the age for peak incidence in women is in the third or fourth decade. The other feature is the fatigability of muscle strength with repeated exercise which distinguishes this patient’s weakness from muscular dystrophy.
