[Optic disc drusen and acute vision loss].

Optic disc drusen (ODD) are calcified nodules within the optic nerve head. These are products of degenerated retinal ganglion cells axoplasmic transport, also known as hyaline or colloid bodies. They are mainly encountered as an incidental benign finding, or as a benign cause of swollen discs (in the differential diagnosis of papilledema). The majority of the patients are asymptomatic, and a slowly progressive sub-clinical visual field loss is found in about 80% of the patients. However, acute painless symptomatic visual field loss, occasionally massive, is rare. This is a case history of 4 patients who developed acute painless visual field loss which was attributed to optic disc drusen. The clinical features and proposed ischemic pathophysiology of acute vision loss and ODD are discussed.

[Exercise induced hyponatremia].

A normal water-electrolyte balance is essential for normal function of body systems during physical activity. During recent years, awareness of the importance of drinking amongst athletes and Israeli Defense Force (IDF) soldiers, in particular, has been highlighted. A large number of athletes tend to drink prior to, during and after their exercise in order to enhance physical abilities and to prevent heat casualties and dehydration. However, excessive water consumption combined with sweat induced electrolytes loss during physical activity, may cause hyponatremia in extreme cases. Recently, several cases of exercise induced hyponatremia were reported in the IDF, resulting from improper water consumption. In this article, we describe a clinical case of exercise-induced hyponatremia in a soldier and a review of the literature, including the etiology, clinical characterization and recommended treatment. Moreover, water consumption recommendations with regard to physical activity are presented. The application of such recommendations may prevent future events of exercise-induced hyponatremia.
