Clinical significance in alcoholic patients of commonly encountered laboratory test results.

An improved understanding of medical problems of alcoholic patients can be gained from commonly encountered laboratory test results. Liver function tests--such as measures of alkaline phosphatase, gamma-glutamyl transpeptidase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase--may provide evidence of altered hepatic activity of different types, such as obstruction and hepatocellular injury. Other test results may indicate impaired hepatic function, such as measurements of albumin, bilirubin, prothrombin time, and blood urea nitrogen. Alterations are also common in electrolytes, blood glucose, magnesium, phosphate, uric acid, and acid-base balance. Disturbances in hematologic function are not infrequent in alcoholic patients, including anemias from many causes, altered granulocyte responses, and thrombocytopenia.

Septic and nonseptic olecranon bursitis. Utility of the surface temperature probe in the early differentiation of septic and nonseptic cases.

Forty-six consecutive cases of olecranon bursitis were prospectively analyzed during a 1-year period. Eleven cases were septic; 35 cases were nonseptic. In addition to bursal fluid analysis, the surface temperature over the involved olecranon bursa and the contralateral (control) olecranon process was obtained by using a surface temperature probe. We compared the temperature difference between the involved and control sides in all septic and nonseptic cases. In nonseptic cases, the mean surface temperature difference was 0.7 degree C vs 3.7 degrees C in septic cases. In all septic cases, the temperature difference was 2.2 degrees C or greater (range, 2.2 degrees C to 5.1 degrees C; SD, 1.1). Use of the surface probe temperature difference proved 100% sensitive and 94% specific in discriminating septic from nonseptic cases. It seems to be more helpful than the bursal fluid leukocyte count, the predominant cell type, or Gram's stain in the early differentiation of septic and nonseptic olecranon bursitis.

Treatment of nonseptic olecranon bursitis. A controlled, blinded prospective trial.

We enrolled 42 patients with nonseptic olecranon bursitis in a double-blind prospective treatment trial to compare the efficacy of an intrabursal steroid preparation with that of an oral anti-inflammatory agent. Patients were randomized into one of four treatment regimens: (1) methylprednisolone acetate (20 mg) intrabursal injection and oral naproxen (1 g/d for 10 days), (2) methylprednisolone acetate (20 mg) intrabursal injection and oral placebo for 10 days, (3) oral naproxen (1 g/d for 10 days), and (4) oral placebo for 10 days. The degree of swelling in millimeters was assessed at study introduction and at 1, 3, and 6 weeks. At 6 months, the number of patients requiring reaspiration for bursitis recurrence was tabulated. Data at 1 week indicated that patients treated with an intrabursal methylprednisolone acetate injection (20 mg) demonstrated the most rapid decrease in swelling. At 6 weeks, the methylprednisolone-treated groups demonstrated sustained improvement. At 6 months, the mean number of reaspirations per patient for reaccumulation of bursal fluid was higher in groups 3 (1.0 +/- 1.2) and 4 (0.4 +/- 0.7). An intrabursal methylprednisolone acetate 20-mg injection seems to be the most effective treatment regimen for nonseptic olecranon bursitis.

Gynecomastia. A worrisome problem for the patient.

Gynecomastia is common in obese or elderly men. Drug-induced breast enlargement is also frequent, whereas other causes of gynecomastia are relatively uncommon. Standardized measurement of breast tissue should be routinely performed in male patients. Diagnostic evaluation should be individualized on the basis of clinical suspicion. Therapy most often involves treating an underlying condition or discontinuing use of an offending drug.

Hematologic effects of acute and chronic alcohol abuse.

Alcoholism affects 3 to 10 per cent of the American population. Alcohol is toxic to all organ systems. This article summarizes current information about the hematologic sequelae of alcohol abuse. A brief summary of ethanol-related metabolic events is followed by discussion of specific disorders of erythrocytes, leukocytes, platelets, and the immune apparatus.

A randomized controlled trial of intravenous streptokinase in evolving acute myocardial infarction.

To determine the efficacy of intravenous streptokinase in acute myocardial infarction, 52 patients were randomized to intravenous streptokinase or control groups. Time from onset of infarction to randomization was similar in the streptokinase group and control group, 4.9 +/- 2.1 hours vs 5.4 +/- 2.4 hours, respectively. The 28 streptokinase patients received an intravenous infusion of 700,000 units of streptokinase followed by full-dose anticoagulation. The 24 control patients received normal saline solution followed by full-dose anticoagulation. Of 28 streptokinase patients, 12 (43%) had noninvasive evidence of reperfusion by early peaking of serum creatine kinase (peak creatine kinase less than 16 hours after onset of infarction) vs 3 of 24 control patients (13%), p less than 0.02. Two streptokinase patients (7%) had reperfusion arrhythmias during streptokinase infusion. One streptokinase patient (4%) and two control patients (8%) died during hospitalization. At angiography (16 +/- 5 days after infarction) 22 of 26 streptokinase patients (85%) had a patent infarct-related coronary artery compared to 8 of 20 control patients (40%), p less than 0.01. Comparison of radionuclide left ventricular ejection fraction assessed acutely (28 +/- 10 hours after infarction) with left ventricular ejection fraction at hospital discharge (15 +/- 3 days after infarction) showed no significant improvement in either the streptokinase or control group, 0% and +1%, respectively. At follow-up 13 +/- 7 months after infarction, total mortality rate was similar in the streptokinase group and control group, 17.8% (5 of 28 streptokinase patients) and 20.8% (5 of 24 control patients), respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Acquired atherosclerotic aortopulmonary fistula presenting as new-onset congestive heart failure.

A middle-aged patient with new-onset congestive heart failure, a loud precordial systolic murmur, and a widened mediastinum on chest radiography is described. Noninvasive studies in addition to the clinical examination suggested an unusual complication of atherosclerotic aortic disease, which was demonstrated at aortography and confirmed at surgery. This case stresses the importance of a careful bedside examination in addition to selective noninvasive studies in patients with new-onset or atypical congestive heart failure.
