Repair of orbital floor fractures: our experience and new technical findings.

We report our experience with the repair of the orbital floor fractures and present new technical findings. We evaluated 30 subjects with pure blowout fractures treated at the Department of Maxillofacial Surgery of the Federico II University of Naples, Italy, between 2005 and 2007. A preoperative examination by computed tomography scans provided classification of the orbital floor fractures into small and large fractures by measurement of the bone defect to choose the appropriate reconstructive implant materials, resorbable or nonresorbable.

Ureteroiliac artery fistula in a young woman with short bowel syndrome for radiation enteritis.

Ureteral-iliac artery fistula is a rare and potentially life-threatening complication, typically occurring after radiation therapy in already surgically treated cancer patients. This case report describes the diagnostic challenges and the successful management, with the positioning of an intra-arterial prosthesis, of a fistula between the internal iliac artery and the left ureter presenting as massive hematuria in a young woman with history of total colectomy and pelvic radiotherapy for rectal cancer and subsequent wide ileal resections and bilateral ureteral stent positioning for radiation enteritis. Ureteroiliac artery fistulas require a prompt diagnosis and intervention, to avoid life threatening clinical events.

Nasal nitric oxide assessment in primary ciliary dyskinesia using aspiration, exhalation, and humming.

Background: Several studies reported low nasal nitric oxide (nNO) levels in subjects with primary ciliary dyskinesia (PCD) and proposed nNO measurement as a diagnostic tool to screen for the disease. All these reports used the aspiration nNO method. The goal of this study was to evaluate nNO in patients with PCD using different methods of NO measurement, including continuous aspiration, silent exhalation, and single-breath humming exhalation, which increases NO wash-out from the paranasal sinuses to the nose.
