Altered sleep patterns, including changes in bedtime, sleep latency, total sleep time, and arising time, have been reported to occur with increasing age. We examine self-reported sleep patterns in a geographically-defined population (n = 3097) of persons aged 65 years and older. Sleep patterns were characterized according to demographic variables, clinical(More)
Epidemic, louse-borne typhus persists in the rugged, mountainous areas of Ethiopia and much of northeastern and central Africa as well as in the rural highlands of Central and South America, where the conditions of living favor the harboring of body lice and where antibiotic treatment and effective louse-control measures are unavailable. The historical(More)
One thousand six surgical patients admitted between April 1983 and January 1984 to a hospital in Addis Ababa were studied for incidence of nosocomial infections. On admission, they were carefully examined clinically to exclude community-acquired infections and to determine any underlying risk factors. All patients were closely followed up for detection of(More)
Skeletal tuberculosis (TB) accounts for about 1-2% of all TB cases and 10% of extrapulmonary TB cases. We present a 19-year-old male with multifocal tubercular osteomyelitis, who presented with progressively worsening back pain, weight loss, fatigue, anorexia, decreased mobility, low-grade fever, and night sweats-but without pulmonary involvement.
The 2.6-megadalton (MDa) cryptic plasmid and the 4.4-MDa beta-lactamase plasmid of Neisseria gonorrhoeae were radiolabeled with [32P] nucleotides and used as probes for direct detection of gonococci and beta-lactamase plasmids in urethral exudates from men with urethritis. The sensitivity and specificity of the DNA probes were compared with culture(More)
Seven hundred patients admitted to the wards of the Department of Obstetrics/Gynaecology of Tikur Anbessa Hospital, Addis Ababa, between January and July 1984 were studied for the incidence of nosocomial infections. The overall hospital infection rate was 17.0%, with wound infection at 47% followed by urinary-tract infection at 15%. Over 80% of the(More)
Patients admitted to a teaching hospital in Addis Ababa were studied for nosocomial infection. Of 2506 patients, 13% developed clinical infections, with the highest rate among obstetric/gynaecologic patients (17.0%). Wound infection was the most frequent type of nosocomial infection (49%) followed by urinary tract infection (25%). Antibiotic prophylaxis was(More)
Legionnaires' disease is primarily a pneumonic process caused by Legionella pneumophilia, a gram-negative aerobic bacillus but also has multiple system involvement. The most common manifestation is encephalopathy suggesting a generalized brain dysfunction but focal neurological manifestations have been reported. We report a patient with Legionella pneumonia(More)
Human immunodeficiency virus (HIV) infection is frequently complicated by a variety of disease processes affecting the central nervous system (CNS). One of them is AIDS dementia complex (ADC), which, in the absence of opportunistic infection, is believed to be caused by HIV itself. ADC is characterized by a constellation of cognitive, motor, and behavioral(More)
Disseminated toxoplasmosis in AIDS is a rare condition. We present an unusual case of a fulminant form of disseminated toxoplasmosis in a young male homosexual. He was a 30-year-old HIV-positive (diagnosed 4 months earlier), admitted with a 5-day history of diarrhea, vomiting, fever, and cough. He had been generally healthy except for an 8-week history of(More)
