The prevalence and causes of visual impairment in young Turkish men.

Objective: To explore the causes and prevalence of visual impairment in young Turkish men.

Methods: The health examination data of the candidates that are saved in National Defense Ministry of Turkey was used. The data of the candidates examined between 1 January 2009 and 31 December 2011 were evaluated.

A permanent junctional reciprocating tachycardia with an atypically located accessory pathway successfully ablated from within the middle cardiac vein.

Permanent form of junctional reciprocating tachycardia (PJRT) is an uncommon form of atrioventricular re-entrant tachycardia due to an accessory pathway characterized by slow and decremental retrograde conduction. The majority of accessory pathways in PJRT are localized in the posteroseptal zone. Despite the high success rate, failure may occur during endocardial radiofrequency catheter ablation due to epicardial insertion of the accessory pathway.

The effect of VVI pacing on P-wave dispersion in patients with dual-chamber pacemakers.

The incidence of atrial fibrillation is higher in patients with VVI pacing mode than DDD pacing mode, but the likely mechanism is not clearly understood. We aimed to evaluate whether short-term VVI pacing increases inhomogeneous atrial conduction by using P-wave dispersion. Forty-seven patients (32 men, 15 women, mean age 54 +/- 13 years) with DDD pacemakers were enrolled in this study.

Hyperbaric oxygenation and antioxidant vitamin combination reduces ischemia-reperfusion injury in a rat epigastric island skin-flap model.

Reperfusion injury, caused by free oxygen radicals, is a chain of events that occurs in tissues exposed to a constant period of ischemia. The antioxidant vitamins E and C (VEC) and hyperbaric oxygenation (HBO) have beneficial effects in treating ischemic tissues following skin flap operations. In our study, we aimed to compare the effects of VEC and/or HBO in ischemia-reperfusion injury induced by free oxygen radicals in an experimental rat epigastric island skin-flap model.

Evaluation of radiation carcinogenesis risk in vertebral hemangioma treated by radiotherapy.

The purpose of this study is to report carcinogenesis risk factor evaluation in vertebral hemangioma patients treated by radiotherapy. Between 1975 and 1995, 29 patients received 20-30 Gy total irradiation dose using conventional fractionation scheme. All the patients had measurements with thermoluminescent dosimeters (TLD 100 ), placed on multiple randophantom sites in vivo within the irradiated volume, to verify irradiation accuracy and calculate carcinogenesis risk factor.

Rotation ligamentoplasty for the correction of epicanthus inversus.

Epicanthus, with its various types, is characterized by an arching fold at the sides of the nose, with a concavity directed laterally. Epicanthus inversus, one of these types, which occurs with varying frequency in all races, is most common among Asians. In epicanthus inversus, the medial canthus is displaced laterally and the medial canthal depression is shallow or absent.
