A rare case of Brugada syndrome induced by hyperglycemia.

Brugada syndrome is a rare genetic disorder of the cardiac sodium channels associated with an increased risk of sudden cardiac death. It is characterized by an electrocardiogram (EKG) showing a right bundle branch block with an elevation in the ST segment. This condition is associated with mutations in several pathologic genes including the most notable mutation in the SCN5A gene, which encodes for a voltage-gated cardiac sodium channel.

An Unusual Presentation of Retinal Detachment and Conjunctivitis: A Case Report.

Introduction: Vision loss is an ophthalmologic emergency with broad differential requiring prompt medical attention.

Case Report: We describe a 55-year-old male presenting to the emergency department (ED) with unilateral, painless visual field deficit with ipsilateral conjunctivitis induced by a presumed foreign body. The patient described a foreign body sensation nine days prior to developing visual changes.

Association of Preoperative, Subjective Pediatric Tonsil Size With Tonsillectomy Outcomes: A Systematic Review.

Importance: Tonsil size assessment on physical examination is often used as a key component of clinical decision-making, specifically in estimating the success or failure of adenotonsillectomy surgery. The accuracy of this approach is not specifically known.

Objective: To systematically review the biomedical literature for data comparing subjective preoperative tonsil (and adenoid) size (0- to >4-point scale) with adenotonsillectomy outcomes using polysomnography and/or quality of life outcomes.

Overexpression of an antioxidant enzyme improves male mating performance after stress in a lek-mating fruit fly.

In many species, courtship displays are reliable signals of male quality, and current hypotheses suggest that these displays allow females to choose males with high cellular function. Environmental stressors generate excess reactive oxygen species (ROS) that impair cellular function, and thus antioxidant pathways that remove ROS are probably critical for preserving complex sexual behaviours. Here, we test the hypothesis that enhanced antioxidant activity in mitochondria preserves mating performance following oxidative stress.
