Background: Recent case reports described three cases of holoprosencephaly (HPE) in the area with high mining-related pollution of the southern region of the Democratic Republic of the Congo (DRC). We reported two male neonates with clinically diagnosed HPE in the localities of Fizi and Kitutu, two mineral areas in the Eastern region of the same country (DRC), where artisanal surface mining is predominant with high exposure to radiation and heavy metals from mining. Cases' presentations: Two newborns from adult and multigravida mothers without pregnancy complication. The birth weights were 3,200 g and 2,500 g, respectively, and the malformations noticed were essentially the single median eye, the absent nose, polydactyly for one case, and proboscis for the other case.They both died a few minutes later after birth. Conclusion:The etiologic factors of HPE remain unknown but seem to be multifactorial from both genetic and environmental factors. We hypothesize under reserve for these two cases that mining and radiation expositions were likely potential environmental associated factors to the occurrence of these malformations.

HighlightsWe report the case of a 84-year-old patient presenting a giant degenerative ruptured aneurysm of the superficial femoral artery. The patient was also operated one year before, for a ruptured aneurysm of the abdominal aorta.This case report is rare, because we described a case of patient with multiple atherosclerotic aneurysms, who present, for the second time, a life threating ruptured aneurysm.Our patient presented, two years before, six synchronic aneurysms without evidence of collagen vascular pathology despite a genetic screening.

Background The prevalence of benign prostate hyperplasia (BPH) varies among individuals from different races or ethnic groups. South-Kivu province (DR Congo) has several morphologically different ethnic groups. Our aim was to compare prostate volume and assess its possible association with specific anthropometric measurements among major ethnic groups. Methods This is a cross-sectional study of male subjects, ≥ 40 year old, enrolled in 10 different sites of South-Kivu allowing both easy access and ethnic diversity. We compared urological features, anthropometric parameters, and body fat composition among 979 subjects who met study criteria: Shi (n: 233), Lega (n: 212), Havu (n: 204), Bembe–Fuliru (n: 172), and minority ethnic groups (n: 158). Results Prostate volume was statistically different among ethnic groups. Median (interquartile range) size of prostate gland was significantly larger in Lega: 55 (38–81) cc, and smaller in Havu, 20 (17, 24) cc; p < 0.001. Overall, an enlarged prostate (≥ 30 cc) was documented in 91% of Lega men, in 59% of intermediate class men (Shi, Bembe–Fuliru, others), and in a mere 11% of Havu men. In multivariate analysis, prostate volume was significantly associated with age (p < 0.001), ethnic group (p < 0.001), residence (p: 0.046), and fasting blood glucose (p: 0.001). Conversely, prostate volume was neither associated with anthropometric parameters, nor with body fat composition. Conclusion Prostatic size varies widely among men from different ethnic origins in South-Kivu. Different genetic determinants and cellular composition of prostatic gland could represent risk factors that need to be examined in forthcoming studies.
