Soluble receptor of advanced glycation end-products (sRAGE) is widely expressed in various organs including male genital tract and spermatozoa. Their regulation depends on many simultaneous conditions that may occur. Male fertility is a multifactorial condition which is influenced by various parameters, some of which are detrimental to the spermatozoa. The aim of this study was to detect possible differences in sRAGE concentrations between serum and seminal plasma of infertile men, compared to fertile men population. ⋯ Serum and seminal plasma sRAGE concentrations seem to show variations worth considering between fertile and infertile men. Moreover, further research is required to elucidate the role of the sRAGEs and oxidative stress in male infertility. HIPPOKRATIA 2017, 21(1): 19-24.

In the past few years, a distinct and multifactorial clinical entity called chronic kidney disease-mineral and bone disorder (CKD-MBD) that leads to decreased bone density and osteoporosis has been identified. The aim of this study was to assess the levels of the matrix metalloproteinase-1 and -2 (MMP-1 and MMP-2) in chronic kidney disease (CKD) patients of various disease stages in correlation to other bone turnover markers (BTM). This study is an initial investigative approach to a possible role of matrix metalloproteinases (MMPs) in the evaluation of bone disease in uremic patients. ⋯ In CKD patients MMP-1 serum levels may reflect increased bone turnover rates.

Hemosiderosis in the absence of blood transfusions has been encountered in conditions associated with ineffective erythropoiesis but not in sickle-cell disease (SCD). Description of the case: We report a case of a 34-year-old Caucasian male, with a history of SCD and beta thalassemia (Hb S/β+-thal) who presented with acute painful crises. Despite never having received regular blood transfusions in the past, the patient demonstrated elevated ferritin levels and transferrin saturation of 83 %. Further evaluation revealed diffuse hepatocellular dysfunction and cirrhosis. ⋯ To the best of our knowledge, this is the first patient with Hb S/β+-thal without a prior history of chronic blood transfusions or other predisposing factors for liver disease who developed hemosiderosis and cirrhosis. The pathomechanism, in this case, is thought to be related to increased duodenal iron uptake secondary to premature red cell precursor death. Further studies are required to characterize ineffective intramedullary erythropoiesis and iron metabolism better, and to improve the existing management guidelines of iron overload. The data reported herein suggest that patients with hemoglobinotpathies should be screened for iron overload regardless of transfusion history. HIPPOKRATIA 2017, 21(1): 43-45.

Amniotic band syndrome (ABS) is a rare disorder which leads to a number of deformities of the fetus body. The treatment depends on the severity of the defect and the extent of the deformity. ⋯ In the case of ABS in DCDA twin pregnancy, conducting a selective termination of the affected fetus creates the opportunity for the proper development of the healthy fetus as well as reaching its full maturity.
