ABSTRACT: In addition to advanced age, factors such as comorbid illness and debility determine the risk of community- acquired pneumonia (CAP). Many elderly persons do not have the classic symptoms of CAP; instead, they may present with confusion, lethargy, tachypnea, anorexia, or abdominal pain. Even with thorough investigation, an infectious pathogen can be identified in only about half of patients. In addition to the causative organisms for pneumonia in younger adults, elderly persons are at risk for infection with organisms such as Haemophilus influenzae, Staphylococcus aureus, enteric gram-negative bacteria, and anaerobes, and for polymicrobial infection. Prompt empiric treatment is essential. Recommended initial therapy choices include a ß-lactam agent with a macrolide, or an antipneumococcal fluoroquinolone.
Bullae had recently appeared on the dorsa of the hands and fingers of a 46-year-old man. His medical history was significant for alcoholism, discoid lupus erythematosus (DLE), and hepatitis C. Systemic lupus erythematosus (SLE) was ruled out; the patient’s symptoms did not meet the American Rheumatism Association criteria for SLE.

ABSTRACT: Recent evidence suggests that viral infection is the most likely underlying cause of Bell's palsy. Rapidity of onset is a clue to the diagnosis; unilateral facial weakness or paralysis develops over 24 to 48 hours. Rule out other causes of peripheral facial paralysis, such as Ramsay Hunt syndrome and Lyme disease. Although most cases of Bell's palsy resolve without medical or surgical intervention, older patients and those with abnormal electroneurographic results are less likely to have complete recovery of facial function. Early treatment with an oral corticosteroid is likely to enhance recovery; concurrent use of acyclovir may also be helpful. Surgical decompression has been effective in patients with abnormal electroneurographic results.
Several lesions had appeared 1 week earlier on the left distal thigh of a 47-year-old woman. The affected area featured erythema with irregular faded borders and central redness with very fine papules over the L3 dermatome. The indurated and tender central areas suggested inflammation or necrosis. There were no vesicles and there was no drainage.
A 60-year-old man presented to the emergency department (ED) with fever of 1 day’s duration and midabdominal pain. The cramping pain had begun 3 days earlier in a bandlike distribution around the upper abdomen. Ingestion of food exacerbated the discomfort. The patient had a history of intermittent constipation; he denied alcohol or illicit drug use, nausea, vomiting, and weight loss. He did not use any herbal or over-the-counter medications.
ABSTRACT: Serum levels of aspartate aminotransferase and alanine aminotransferase that exceed 1000 IU/L indicate acute viral hepatitis (A, B and, rarely, C), acute drug toxicity (eg, acetaminophen overdose or isoniazid hepatotoxicity), or ischemic liver injury. In chronic hepatitis (ie, hepatitis B or C or autoimmune), values range from mildly elevated to usually less than 400 IU/L. Elevated levels of alkaline phosphatase and gamma;-glutamyltransferase (GGT) are consistent with cholestatic disease: primary biliary cirrhosis, primary sclerosing cholangitis, idiosyncratic drug reactions, or mechanical biliary obstruction (eg, biliary stones or tumor). Elevation in the GGT level can also be induced by alcohol consumption or medications (eg, phenytoin). Isolated unconjugated hyperbilirubinemia suggests Gilbert syndrome or a hematologic disorder; conjugated hyperbilirubinemia reflects impaired hepatic excretion. Serum bilirubin and albumin and INR have prognostic significance in chronic liver disease; bilirubin and INR are more useful in acute liver failure because albumin has a long half-life.
