Electron microscopic evaluation of the effect of therapeutic silicone hydrogel lenses on the limbal area.

Purpose: To investigate the effects of high-permeability silicone hydrogel contact lenses used for therapeutic purposes on limbal cells, inflammation, and neovascularization.

Methods: Bullous keratopathy was induced by injection of 0.05% benzalkonium chloride into the anterior chamber of 20 anesthetized rabbit eyes.

Endovascular stent-graft placement for the management of a traumatic axillary artery pseudoaneurysm-a case report.

A 24-year-old woman with a right infraclavicular gunshot wound developed an axillary artery pseudoaneurysm. She was successfully treated by using a 5 cm Hemobahn stent-graft with a diameter of 6 mm. Postimplantation arteriography revealed normal flow through the axillary artery without evidence of leakage of contrast medium.

Resveratrol, a red wine polyphenol, protects spinal cord from ischemia-reperfusion injury.

Objective: The cardioprotective effect of red wine has been attributed to resveratrol. The resveratrol-induced protection against ischemia-reperfusion (I/R) injury has been documented in heart, kidney, and brain. Resveratrol scavenges free O(2) radicals and upregulates nitric oxide (NO).

The effects of preoperative inflammation on the analgesic efficacy of intraarticular piroxicam for outpatient knee arthroscopy.

Unlabelled: We conducted a double-blinded study in 90 patients undergoing elective arthroscopic knee surgery to determine whether there is a role of inflammation in the analgesic efficacy of intraarticular piroxicam. Standardized general anesthetic techniques were used for all patients. At the end of the operation, after harvesting synovial biopsies, patients were randomized into three intraarticular groups equally.

Emergency thoracotomy for blunt thoracic trauma.

Objectives: The indications for emergency thoracotomy are controversial for blunt trauma. The best results were seen in those patients who were stable enough to undergo thoracotomy in the operating theatre and survived the operation.

Methods: The hospital records of 29 patients who underwent emergency thoracotomy for blunt thoracic trauma were reviewed.

Descending necrotizing mediastinitis: a case report and review of the literature.

Descending necrotizing mediastinitis (DNM) is a highly fatal disease and as infection spreads along deep cervical planes into the mediastinum, widespread cellulitis, necrosis, abscess formation, and sepsis may occur. Early diagnosis is crucial for starting aggressive treatment without delay. Cervicothoracic computed tomography (CT) scanning may be useful for early diagnosis and preoperative evaluation of the surgical approach.

Biochemical and hemodynamic effects of ascorbic acid and alpha-tocopherol in coronary artery surgery.

This study was undertaken to evaluate the effects of alpha-tocopherol and ascorbic acid on markers of myocardial reperfusion injury and myocardial contractile function after coronary artery surgery. Forty-eight patients were divided into 4 groups; 300 mg/day alpha-tocopherol was given orally to the patients in group I for 14 days. In groups II and III, 4g of ascorbic acid was administered intravenously prior to induction and in the cardioplegic solution, respectively.

Transdiaphragmatic intercostal hernia following a penetrating thoracoabdominal injury: report of a case.

Intercostal hernias with abdominal viscera have rarely been reported following penetrating accidental or surgical trauma. We report herein a case of a traumatic rupture of the left hemidiaphragm, presenting as an intercostal hernia 2 years after a penetrating thoracoabdominal injury. The diaphragmatic rupture had been initially very small and could not be detected in the serial chest films and abdominal computed tomographic scans.
