Trends of renal diseases in Germany: review of a regional renal biopsy database from 1990 to 2013.

Background: Several renal biopsy registries in Europe have shown geographical and temporal variations in the patterns of renal diseases. However, there is a lack of current data on trends of renal disease in Central Europe.

Methods: After exclusion of transplant and re-biopsies, the renal biopsy registry of the German RWTH Aachen University Hospital included data of 1208 biopsies over a period of 24 years (1990-2013).

Prognostic impact of renal arterial resistance index upon renal allograft survival: the time point matters.

Background: The renal arterial resistance index (RI) is reported to be a significant predictive parameter for renal allograft failure or death. The influence of the time point after renal transplantation on its predictive power has not been sufficiently evaluated. We performed a retrospective analysis of RI and its power to predict renal allograft failure or death with special emphasis on the time point of RI measurement.

[Pulmonary alveolar microlithiasis--a rare cause of bilateral extensive pulmonary infiltrates].

Background: Pulmonary alveolar microlithiasis is a rare disease, which is characterized by pulmonary deposition of calcium phosphate microliths. The radiographic features can be pathognomonic with a "sandstorm"-like opacification throughout the lungs.

Case Report: A 29-year-old Moroccan presented for the first time 1988 with atypical chest pain.

Heterotaxy syndrome with severe pulmonary hypertension in an adult.

Heterotaxy syndrome is a rare clinical entity in adults, characterized by situs ambiguus, congenital heart defects, and splenic malformations. We report the case of an adult with heterotaxy syndrome (including situs ambiguus, bilateral superior vena cava, hypoplastic right-sided spleen and portosystemic shunts) presenting with dyspnea due to severe pulmonary hypertension. Vasodilatory therapy was initiated, leading to marked reduction of clinical symptoms.
