Cerebrospinal Fluid Output as a Risk Factor of Chronic Hydrocephalus After Aneurysmal Subarachnoid Hemorrhage.

Background: Chronic shunt-dependent hydrocephalus is a well-known complication of subarachnoid hemorrhage. Although the risk factors have been extensively investigated, most fail to predict permanent shunt dependency. It is unknown whether the volume of cerebrospinal fluid (CSF) from external ventricular drainage and the daily volume of drainage during the acute hydrocephalus phase (first 72 hours) can predict shunt dependency.

Validation of shunt dependency prediction scores after aneurysmal spontaneous subarachnoid hemorrhage.

Background: Currently available scores for predicting shunt dependency after aneurysmal spontaneous subarachnoid hemorrhage (aSAH) are limited and not widely accepted. The key purpose of this study was to validate a recently created score for shunt dependency in aSAH (SDASH) in an independent population of aSAH patients. We compared this new SDASH score based on a combination of the Hunt and Hess grade, Barrow Neurological Institute (BNI) score, and the presence or not of acute hydrocephalus with other published predictive scores.

Sentinel Node Biopsy in Special Histologic Types of Invasive Breast Cancer.

Objective: To assess the feasibility of sentinel node biopsy (SNB) in ductal and lobular invasive breast cancer, a group of tumors known as special histologic type (SHT) of breast cancer.

Materials And Methods: Between January 1997 and July 2008, 2253 patients from 6 affiliated hospitals underwent SNB who had early breast cancer and clinically negative axilla. The patients' data were collected in a multicenter database.

Radioguided localization of nonpalpable breast cancer lesions: randomized comparison with wire localization in patients undergoing conservative surgery and sentinel node biopsy.

Objective: The aim of this investigation was to determine whether radioguided occult lesion localization and routine wire localization differ in respect to the effectiveness of complete excision of nonpalpable breast cancer lesions.

Subjects And Methods: This prospective randomized study included patients with breast cancer scheduled for conservative tumor excision and sentinel node biopsy. Patients were randomized to either radioguided localization or wire localization.
