In 1967, several workers involved in poliomyelitis vaccine development and production fell ill at three different locations in Europe with a severe and often lethal novel disease associated with grivets (Chlorocebus aethiops) imported from Uganda. This disease was named Marburg virus disease (MVD) after the West German town of Marburg an der Lahn, where most human infections and deaths had been recorded. Consequently, the Marburg episode received the most scientific and media attention. Cases that occurred in Frankfurt am Main, West Germany, were also described in commonly accessible scientific literature, although they were less frequently cited than those pertaining to the Marburg infections. However, two infections occurring in a third location, in Belgrade, Yugoslavia, have seemingly been all but forgotten. Due in part to their absence in commonly used databases and in part to the fact that they were written in languages other than English, the important articles describing this part of the outbreak are very rarely cited. Here, we summarize this literature and correct published inaccuracies to remind a younger generation of scientists focusing on Marburg virus and its closest filoviral relatives of this important historical context. Importantly, and unfortunately, the three episodes of infection of 1967 still represent the best in-depth clinical look at MVD in general and in the context of "modern" medicine (fully resourced versus less-resourced capacity) in particular. Hence, each individual case of these episodes holds crucial information for health care providers who may be confronted with MVD today.

Introduction. Juxtaglomerular cell tumor (JGCT) or reninoma is a very rare cause of curable hypertension among young people. The early diagnosis is the most important based on the clinical presentation, hormonal and radiological findings observed on computed tomography (CT) and/or magnetic resonance imaging (MRI). The final confirmation of the JGCT is the lateralization of the plasma renin activity (PRA) during the selective renal venous sampling. Case report. This report presents a typical case of young women with JGCT which was manifested for the first time with severe hypertension during the pregnancy and was the reason of fetal death. After the miscarriage, the diagnosis of JGCT was made by the CT scanning and confirmed by the selective renal venous sampling. After the partial nephrectomy, the blood pressure and serum potassium normalized without the medications. Conclusion. Reninoma should be considered in the differential diagnosis as a cause of severe hypertension in pregnancy and also should be suspected in young hipertensives (especially females) with hypokalemia and secondary hyperaldosteronism after the exclusion of other causes particularly renal artery stenosis. A dynamic contrastenhanced CT, MRI and selective renal venous sampling are the most important tools in the diagnosis of JGCT.

Variola (smallpox) virus is classified as class A of potential biological weapons, due to its microbiological, genetic, antigenic and epidemiological characteristics. The potential danger is more real because vaccination against smallpox has stopped since disease eradication in 1979. That is why we want to share our unique, rich experience and acquired knowledge in the fight against this highly contagious and deadly disease during the smallpox outbreak in ex-Yugoslavia in 1972. It was the largest postwar outbreak in Europe when there were officially registered 175 ill patients, 35 of them with lethal outcome. This outbreak was specific by the time of its occurrence, the affected territory, dimensions and some epidemiological characteristics, but also by the well-organized, synchronized and efficient reaction of the competent state services in the fight against it.

SUMMARYHantaviruses are endemic in the Balkans, particularly in Serbia, where sporadic cases and/or outbreaks of hantaviral human disease have been reported repeatedly, and evidenced serologically. Here, we present genetic detection of Dobrava-Belgrade virus (DOBV) hantaviral sequences in wild rodents trapped in central Serbia. All the animals were pre-screened serologically by indirect immunofluorescence (IF) test and only those with a positive finding of hantaviral antigens were further tested by polymerase chain reaction. Of the total of 104 trapped animals, 20 were found to be IF positive and of those three were positive for hantaviral RNA: one Microtus arvalis for Tula virus, and one each of Apodemus agrarius and Glis glis for DOBV. Phylogenetic analysis of the obtained sequences implies putative DOBV spillover infection of A. agrarius and G. glis from Apodemus flavicollis. However, future investigations should help to identify the most common natural host and geographical distribution of DOBV in its reservoir hosts in Serbia.
