[Antiphospholipid syndrome and retinal vein occlusion. Meta-analysis of Published Studies]. / Antiphospholipidsyndrom und retinale venöse Verschlüsse. Metaanalyse publizierter Studien.

The role of antiphospholipid syndrome (APS) in the pathogenesis of retinal vein occlusion has been discussed for several years. Conflicting results of the published studies are caused by small numbers of investigated patients and lack of control groups. We performed a meta-analysis of all case-control studies published up to July 2007 that investigated the prevalence of APS according to current diagnostic criteria for this syndrome.The results of meta-analysis show a significantly higher prevalence of APS in patients with retinal vein occlusion compared with controls. Patients with APS are treated with anticoagulants to reduce the risk of recurrence of thrombosis. Therefore, screening for APS seems to be indicated in all patients with retinal vein occlusion, and, in the case of a positive result, initiation of anticoagulation. For patients with retinal vein occlusion with APS, no data are currently available regarding the recurrence of thrombosis. To give a clear recommendation, a prospective randomized study is required to investigate the benefit of anticoagulation.

Physical efficiency of 10-16-year-old boys with hearing impairment.

PURPOSE: The aim of our investigation was to estimate on hand of the above the physical efficiency value of hearing impaired children and compare them with healthy counterparts. MATERIAL AND METHODS: The investigation covered a group of 63 boys, 27 with hearing impairment (HI) and 36 healthy (R), 10-16 years old. The investigated subjects were divided into 2 groups according to their age: 10-12 and 14-16-year-old boys. For determination of cardio-respiratory system efficiency PWC170 (Physical Working Capacity) test was performed. PWC170 and VO2max indices were calculated using proper mathematical equations. RESULTS: The comparison of PWC170 and VO2max indices shows no statistically significant differences between investigated groups. Boys from younger HI group obtained higher PWC170 and VO2max values than boys from R group. In older groups, values of investigated indices were inversed in relation to younger groups. Boys from R group obtained higher values of investigated indices. CONCLUSIONS: Results received shows some trend, which is probably connected with isolation and absence of cohesion between auditory organ rehabilitation and physical efficiency development. There is necessity of integration programs construction, which will influence on comprehensive and proper growth of hearing impaired children.
