Conservative management of avascular necrosis of the metacarpal head: A case report and brief review.
Avascular necrosis (AVN) of the metacarpal head is rare, and there is no clear consensus on treatment. The main aim of this study was to discuss the possible pathologic-mechanics of its development, epidemiology, radiographic features, and outcome after conservative treatment. ⋯ Metacarpal head necrosis typically occurs in adolescent patients with a history of trauma. Conservative treatment may sometimes have an excellent prognosis.

Low vision rehabilitation in improving the quality of life for patients with impaired vision: A systematic review and meta-analysis of 52 randomized clinical trials.
Low vision rehabilitation optimizes the use of residual vision after severe vision loss, but also teaches skills to improve visual functioning in daily life. These skills promote independence and active participation in society. This meta-analysis was designed to evaluate the efficacy of low vision rehabilitation in improving the quality of life (QoL) in visually impaired adults. ⋯ This meta-analysis indicated that low vision rehabilitation interventions, particularly psychological therapies and methods of enhancing vision, may improve vision-related QoL and visual functioning in people with sight loss compared to usual care. Further studies should explore longer maintenance effects and the costs of several types of low vision rehabilitation. Studies characterizing the mechanisms of rehabilitation interventions in different settings, including low-income countries, are also required.

Evaluation of association between methylenetetrahydrofolate reductase and azoospermia: A meta-analysis.
Infertility affects childbearing age couples all over the world. One of the important reasons for infertility is genetic factors. Our study evaluated the association between methylenetetrahydrofolate reductase (MTHFR) and azoospermia. ⋯ There was association between MTHFR polymorphism and azoospermia. Caucasian populations had higher risk than Mongolian populations in association between MTHFR and azoospermia.
