Although first-line therapy for bronchial asthma has changed over the past decade to anti-inflammatory medication such as inhaled corticosteroids and cromolyn with possible addition of beta-agonists, theophylline is still useful and therefor widely used. However, several studies have raised serious questions regarding its efficacy in acute asthmatic exacerbations. These studies, the narrow therapeutic range of the drug, the frequency of side effects and interactions with common drugs, and individual variation in clearance and metabolism, have prompted its reevaluation in the management of asthma. Therapeutic serum levels of theophylline are between 10 to 20 mcg/ml. Most adults achieve these concentrations with daily slow-release oral theophylline preparations, 200-400 mg (approximately 10 mg/Kg) twice a day. However, when such a patient presents to the emergency room (ER) in an asthmatic attack, immediate intravenous theophylline is often given, regardless of maintenance treatment. Since the rationale for this common therapeutic approach has been challenged, the current study was undertaken. Serum theophylline levels were measured in 23 consecutive asthmatics presenting to the ER in an acute attack. 15 (68%) had therapeutic levels (above 10 mcg/ml) and 2 had toxic levels (above 20 mcg/ml), prior to receiving the standard intravenous theophylline dose given for an attack. These data indicate that most patients with bronchial asthma on oral maintenance theophylline do not require additional intravenous theophylline when in an attack. It probably will not benefit them and may even induce serious theophylline toxicity.

Characteristics of Hospitalized Alcoholics

Residential Center for Alcoholics and Israel Society for the Prevention of Alcoholism, Ramat Gan

The background characteristics of 1,173 alcoholics hospitalized for 3 months in this center during December 1982 to December 1994 were reviewed. Socio-demographic variables and termination-of-treatment data, are described. The profile of the typical hospitalized alcoholic was that of a Jewish, urban, married, unemployed man, born in Asia-Africa (or in Israel) who had been living for many years in Israel and had many children and a low educational level. They usually start drinking in adolescence and come to the center after more than 15 years of drinking, mainly at home and alone, and also have family relatives who drink. Implications of the data for treatment and for family physicians are presented.

Typhlitis

Typhlitis (from Greek, "typhlon", cecum) is an inflammatory process involving the cecum and ascending colon צ in neutropenic patients after chemotherapy. Early diagnosis and treatment is of great importance, since the mortality is high. In the past decade there has been an increasing number of reports, as well as impressive improvement in diagnosis, and treatment. We describe 2 patients treated in our department. We emphasize the evolving changes in the management of these patients, from early surgical intervention to conservative treatment, and the problem of prophylactic treatment for those who survive an episode of typhlitis.

Acute Effusive Constrictive Pericarditis in Influenza A

Constrictive pericarditis may complicate the course of several viral infections, mainly Coxsackie virus group B, as well as in rheumatoid disease, radiation and neoplasm. Perimyocardial involvement during influenzal infections is usually mild and does not progress to constriction or tamponade. A single case of cardiac tamponade caused by influenza A was reported in 1986. We report a case of acute effusive-constrictive pericarditis due to influenza A infection. Corticosteroids resulted in some benefit, but did not relieve constriction, which required extensive pericardiectomy.
