Continuous measurement of cerebral oxygenation with near-infrared spectroscopy after spontaneous subarachnoid hemorrhage.

Objective. The aim of our prospective study was to investigate the applicability and the diagnostic value of near-infrared spectroscopy (NIRS) in SAH patients using the cerebral oximeter INVOS 5100C. Methods.

Special features of subarachnoid hemorrhage of unknown origin: a review of a series of 179 cases.

Objectives: The aim of this study was to work out the special features of subarachnoid hemorrhage (SAH) of unknown origin in respect of diagnostic evaluation, clinical course, and outcome in a large cohort of patients.

Methods: We reviewed the data of 179 patients with SAH of unknown origin during 1991 and 2008. The differentiation between perimesencephalic (PM-SAH) and non-perimesencephalic SAH (NON-PM-SAH) was done under consideration of the bleeding pattern on CT scanning.

Does magnetic resonance imaging produce further benefit for detecting a bleeding source in subarachnoid hemorrhage of unknown origin?

Background: Spontaneous subarachnoid hemorrhage (SAH) without evidence of a bleeding source on the first digital subtraction angiogram (DSA) - also called SAH of unknown origin - is observed in up to 27% of all cases. Depending on the bleeding pattern on CT scanning, SAH can be differentiated into perimesencephalic (PM-SAH) and non-perimesencephalic SAH (NON-PM-SAH). The aim of our study was to investigate the effectiveness of magnetic resonance imaging (MRI) for detecting a bleeding source in SAH of unknown origin.

Symptomatic spinal cavernous malformations: indication for microsurgical treatment and outcome.

Purpose: We demonstrate clinical features, therapy and outcome of 14 patients with symptomatic spinal cavernous malformations (CM).

Methods: We retrospectively reviewed all patients who underwent microsurgical treatment of symptomatic spinal CM during the last decade in our department through an analysis of our database.

Results: We analyzed the data of 14 patients (11 females, 3 males) with symptomatic spinal CM in a range of 16-77 years (mean age 47.

Diagnostic value of magnetic resonance imaging in perimesencephalic and nonperimesencephalic subarachnoid hemorrhage of unknown origin.

Object: The aim of this study was to evaluate the diagnostic value of MR imaging in perimesencephalic (PM) and nonperimesencephalic (non-PM) subarachnoid hemorrhage (SAH) of unknown origin.

Methods: The authors conducted a retrospective review of all patients with SAH (1226 patients) in their department between January 1991 and December 2008. Included in the study were cases of spontaneous SAH diagnosed using CT scans obtained within 24 hours of the initial symptoms and initially negative digital subtraction (DS) angiograms.

Treatment of cutaneous leishmaniasis with cryosurgery.

Background: The management of cutaneous leishmaniasis with topical methods, if effective, can spare patients from long and costly inpatient treatments.

Methods: Seventeen patients with cutaneous leishmaniasis were treated with cryosurgery using liquid nitrogen as the cryogen. Two cycles of 10-30 s freezing time were used and repeated at 3-week intervals.
