[Transmission of acquired immunodeficiency syndrome among intravenous drug abusers in Belgrade].

The prevalence of HIV infection among intravenous drug addicts (IVDAs) was 11% in Belgrade in 1997 (500 IVDAs). There are only two ways of transmission of HIV infection among IVDAs: the use of contaminated needles and syringes and sexual intercourse with an infected partner.

The distribution of 58 newly discovered cases in a 7-year survey period showed that the average annual incidence rate was 0.

Epidemiological and clinical characteristics of ALS in Belgrade, Yugoslavia.

[Frontal lobe dysfunction in ALS].

We present the facts on kind and frequency of disorder of high cortical functions in amyotrophic lateral sclerosis. It was considered for a long time that this disease affects selectively motor neurons. The signs of degeneration found in other structures and associated signs of other neurological disorders brought the diagnosis of amyotrophic lateral sclerosis under suspicion.
