There are few population-based studies of the natural history and epidemiology of herpes zoster. Although a relatively common cause of morbidity, especially among the elderly, contemporary estimates of herpes zoster incidence are lacking. Herein we describe a population-based investigation of incident and recurrent herpes zoster from 1990 through 1992 in a health maintenance organization. ⋯ The recorded incidence of herpes zoster was 64% higher than that reported 30 years ago; the age-standardized rate was more than twofold higher. Immunosuppressive conditions had little impact on overall incidence, although they were strongly associated with early recurrences.

Intravenous drug use is an increasingly common condition predisposing to infective endocarditis. Data on infective endocarditis in intravenous drug users are limited. ⋯ Infective endocarditis in intravenous drug users affects the right and left sides of the heart with approximately equal frequency. At present, more than 90% of cases of infective endocarditis in intravenous drug users in Chicago are caused by staphylococci or streptococci. Involvement of the aortic valve is predictive of increased morbidity and mortality in intravenous drug users with infective endocarditis. With medical treatment, and surgery when medical treatment fails, intravenous drug users with infective endocarditis have an in-hospital survival rate of 91%.

To determine the incidence of perioperative complications in asthmatic patients who received preoperative treatment with corticosteroids and whether these could be predicted using any study variables such as age, sex, severity of asthma, or surgery type. ⋯ Asthmatic patients who are treated preoperatively with corticosteroids can undergo surgical procedures with a low incidence of complications.

Randomized Controlled Trial Clinical Trial
Early switch from intravenous to oral cephalosporins in the treatment of hospitalized patients with community-acquired pneumonia.
Switch therapy is defined as the early transition from intravenous to oral antibiotics during treatment of infection. This study was designed to evaluate the clinical outcome and length of stay of hospitalized patients with community-acquired pneumonia treated with an early switch from intravenous to oral third-generation cephalosporins. ⋯ This investigation demonstrated that an early switch to oral cefixime may be reasonable in hospitalized patients with community-acquired pneumonia who have already shown a good clinical and laboratory response to therapy with intravenous third-generation cephalosporins. This approach is clinically effective and minimizes hospital stay.

To determine the effect of location within the hospital and preexisting electrocardiographic rhythm on the outcome of cardiopulmonary resuscitation, the cardiopulmonary resuscitation records for a 3-year period, including 668 hospitalized patients, were retrospectively reviewed. ⋯ Futile resuscitative efforts are routinely performed in part because physicians and patients are unaware of outcome results and factors that influence survival. A wider recognition of the limitations of cardiopulmonary resuscitation should lead to advanced directives that reflect this awareness, with substantially more patients choosing not to have cardiopulmonary resuscitation.
