After the first case of HIV-infection had been diagnosed in 1986 in a Northern district of Zimbabwe, a local hospital based surveillance system, was introduced. In order to monitor the spread of the epidemic in the district, residence, age, sex and clinical presentation of all newly diagnosed HIV-patients were recorded. After three years, the data were compiled and analysed with the following results. Altogether 887 symptomatic HIV-patients (0.5 pc of the district population) were diagnosed. The most common HIV-associated signs and symptoms were PGL (47 pc), chest infection (29 pc), herpes zoster (24 pc) and chronic STDs (15 pc). The female-to-male ratio in adults was 1.4. The average age on diagnosis in women was 26.0 +/- 6.7 years and in men 30.7 +/- 8.6 years. The three years' cumulative incidence of HIV-cases was 27.2/1,000 in the urban area and 3/1,000 in the rural areas of the district.

Objective: To evaluate the effects of bapineuzumab on brain β-amyloid (Aβ) burden using (11)C-Pittsburgh compound B ((11)C-PiB)-PET.
Methods: Two phase 3 clinical trials, 1 each in apolipoprotein APOE ε4 carriers and noncarriers, were conducted in patients with mild to moderate Alzheimer disease dementia. Bapineuzumab, an anti-Aβ monoclonal antibody, or placebo, was administered by IV infusion every 13 weeks for 78 weeks.

Background: Bapineuzumab, a humanized anti-amyloid-beta monoclonal antibody, is in clinical development for the treatment of Alzheimer's disease.
Methods: We conducted two double-blind, randomized, placebo-controlled, phase 3 trials involving patients with mild-to-moderate Alzheimer's disease--one involving 1121 carriers of the apolipoprotein E (APOE) ε4 allele and the other involving 1331 noncarriers. Bapineuzumab or placebo, with doses varying by study, was administered by intravenous infusion every 13 weeks for 78 weeks.
