Prevalence of congenital cryptorchidism in Estonia.

Background: Cryptorchidism is one of the most common urogenital malformations. Cryptorchidism prevalence varies greatly in different countries and populations. The aim of the current study was to determine and analyse cryptorchidism prevalence in Estonia.

Increased Blood Levels of Growth Factors, Proinflammatory Cytokines, and Th17 Cytokines in Patients with Newly Diagnosed Type 1 Diabetes.

The production of several cytokines could be dysregulated in type 1 diabetes (T1D). In particular, the activation of T helper (Th) type 1 (Th1) cells has been proposed to underlie the autoimmune pathogenesis of the disease, although roles for inflammatory processes and the Th17 pathway have also been shown. Nevertheless, despite evidence for the role of cytokines before and at the onset of T1D, the corresponding findings are inconsistent across studies.

Expression of B7 and CD28 family genes in newly diagnosed type 1 diabetes.

Type-1 diabetes (T1D) is caused by T-cell mediated autoimmune reaction directed against the insulin-secreting beta cells. We hypothesized that in addition to antigen/MHC recognition the co-stimulatory B7 and CD28 pathway is also strongly affected in T1D. CD80, CD86, CD28, CTLA4, ICOS and CD25 mRNA expression was characterized in 49 newly diagnosed young T1D patients (mean age 11 ± 5 years, 25 male/24 women) and 31 controls (mean age 14 ± 7 years, 14 male/17 women).
