Well water characteristics and the Balkan nephropathy.

A total of 366 inhabitants of a village affected by Balkan nephropathy (BN) have been followed over 12 years. It was shown that depth of the well to the water level, height of the water column, electroconductivity, and NO3 content of the water were not associated with BN. The risk of developing the disease was significantly higher if a well was at a lower altitude and contained a higher concentration of SiO2. Low altitude might have been expected to correlate with the BN frequency; as for silica, however, there are sound indications that it could just be a correlate of a cause rather than a direct determinant of BN.

Upper urothelial tumours and the Balkan nephropathy. Inference from the study of a family pedigree.

In an area heavily affected by both Balkan nephropathy (BN) and upper urothelial tumours (UUT), an outbreak of UUT (followed later by BN) affected at least four of five siblings. Their cousins developed BN in a high proportion but no one of them had any sign of UUT. It has been suggested that host factors determine the outcome of exposure to the same agent(s) responsible for both diseases.

HIV seropositivity in a Yugoslav prison population.

An estimated number of HIV infected individuals in Yugoslavia might be about 3000. I.v. drug users are by far the most affected population group. Prevalence of HIV seropositivity among imprisoned drug users in Belgrade approaches 50%. An effective control of unvoluntary homosexual contacts in prisons is not feasible. Having in mind a moral obligation of the society to preserve the health of its confined members, we advocate the right of (voluntary or on request screened) HIV seronegative individuals to chose to share the cell with inmates shown to be HIV seronegative as well.

Aetiology of Balkan nephropathy: a reappraisal after 30 years.

Balkan nephropathy (BN) has been a complete aetiological puzzle for many years. Intense research produced many controversial results, but also helped some clues to be traced. Thus, it became rather obvious that the disease is caused by environmental factors (though it may be, to some extent, genetically controlled). Among live agents, slow viruses are the only (and theoretically very attractive) possible cause of both BN and urothelial tumours, which occur frequently in BN endemic areas. Apart from occasional visualization of virus-like particles, other evidence supporting this hypothesis has been lacking. The role biological products, particularly fungal toxins, needs to be further defined. An excess of any heavy metal or radioactive substance as a cause of BN is very unlikely indeed; however, a deficiency of a bio-essential element could not be ruled out. Many epidemiological data indicate that water might be a transmitter of the agent(s). A wide range of ions and minerals have been incriminated, but up to now most of the studies have provided negative or inconclusive results. Organic compounds in well water have never been sufficiently considered. Another ignored area are unstable and, particularly, photosensitive substances. Fertilizers, pesticides, analgesics, local herbs and teas have no causal relation to BN.

Increased frequency of Rh(E) in acute appendicitis.

In 64 children with histopathologically confirmed acute appendicitis, the Rh(E) antigen was found to be more frequent than in corresponding, ethnically and geographically matched controls. The Rh phenotype responsible for the increase of E appeared to be CcD-Ee. The difference was highly significant and supported the hypothesis of a polygenic predisposition to acute appendicitis.
