Posterolateral plate fixation with Talarlock is more stable than screw fixation in ankle arthrodesis in a biomechanical cadaver study.

Background: A number of studies report on limitations of the screw arthrodesis in severe malalignment of the hindfoot, neuropathic deformity, poor bone quality and osteoporosis.

Methods: Fourteen anatomically correct polyurethane foam models of the right leg (Sawbones Europe, Malmö, Sweden) and eighteen fresh-frozen human lower leg specimens (9 pairs) were used for the comparative biomechanical testing.

Results: The statistical analysis of the stiffness of the fixation developed a significant difference in favor of the plate in all test directions.

Efficiency test of current carotid embolic protection devices.

Embolic protection devices were developed to reduce the risk of stroke during carotid artery stenting. The aim of this study was to test the capture efficiency of five embolic protection devices under reproducible in vitro conditions. The setup consisted of silicone tubes representing the vessel modeling round and oval cross sections.

Extrarenal Manifestations in Shigatoxin-associated Haemolytic Uremic Syndrome.

Background: Shigatoxin-associated haemolytic uremic syndrome (STEC-HUS) is the most frequent cause of acute kidney injury in children worldwide. Extrarenal manifestations are the main determinants for both, short- and long-term prognosis of patients with STEC-HUS.

Patients: 46 patients treated over the last 10 years for STEC-HUS in a single center.

[Fertility of workers exposed to herbicides and pesticides].

Twenty-one workmen exposed to herbicide as organic mercury compounds and to pesticide as halogenic hydrocarbon has been investigated concerning their fertility. If the concentrations of organic mercury compounds increase in the air of the place of employment then the levels of this heavy metal are also higher in the urine and in the ejaculate, and the fertility is reduced. It could also be established that a correlation exists between the concentration of pesticide in the place of employment and the male fertility, especially in cases with an excess of maximum permitted concentrations.

[Prevention of occupational and community health problems using Falisan Universal liquid caustic].

Based on tests with Falisan-Universal fluid caustic the authors report on measuring results of laboratory tests and analyses of utilization. The air pollution caused by the active agent phenyl mercury acetate and the formulation remedy dimethylformamide is assessed. Conclusions are made for the caustic's application and for its tests.
