Impact of Early Reoperation on the Prognosis of Patients Operated on for Glioblastoma.

Background: The prognosis for patients with glioblastoma depends particularly on the degree of tumor resection. Patients with tumor remnants in postsurgical magnetic resonance imaging (<72 hours) may benefit from early reoperation. We present our results concerning the impact on overall survival (OS) and progression-free survival (PFS) of reoperation in patients who have already undergone surgery for glioblastoma.

A prospective study on the correlation between thromboelastometry and standard laboratory tests - influence of type of surgery and perioperative sampling times.

This prospective study aimed at investigating the influence of surgery type and perioperative sampling times on the correlations between rotational thromboelastometry (ROTEM) parameters and standard laboratory coagulation tests assessing comparable coagulation phases. Patients undergoing glioblastoma multiforme resection (GBR group,  = 60) or laparoscopic colon cancer resection (CCR group,  = 40) were prospectively included. Blood samples for ROTEM and laboratory assessments were consecutively drawn within 24-hours prior to surgery (baseline), and at 2, 24 and 48-hours after surgery.

Breast cancer risk and genetic ancestry: a case-control study in Uruguay.

Background: Uruguay exhibits one of the highest rates of breast cancer in Latin America, similar to those of developed nations, the reasons for which are not completely understood. In this study we investigated the effect that ancestral background has on breast cancer susceptibility among Uruguayan women.

Methods: We carried out a case-control study of 328 (164 cases, 164 controls) women enrolled in public hospitals and private clinics across the country.

[Emergency transcranial doppler ultrasound: predictive value for the development of symptomatic vasospasm in spontaneous subarachnoid hemorrhage in patients in good neurological condition].

Purpose: To examine the predictive value of an early transcranial Doppler ultrasound (TCD) study performed in the emergency department in patients with spontaneous subarachoniod hemorrhage (SAH) in good neurological condition, in order to know which patients are at high risk of developing delayed cerebral ischemia (DCI).

Design: A descriptive observational study was carried out involving a period of 3 years.

Setting: Critical Care and Emergency Department.

Creatine supplementation does not affect clinical health markers in football players.

Purpose: To study the effects of 8-week creatine monohydrate (CrM) supplementation on blood and urinary clinical health markers in football players.

Methods: 14 football players were randomly assigned in a double-blinded fashion to Cre (n = 7) or Pla (n = 7) group. The Cre group ingested 15 g/day of CrM for 7 days and 3 g/day for the remaining 49 days, whereas the Pla group ingested maltodextrin following the same protocol.

Historical landmarks in vascular neurosurgery "On July 10th 2006, at the 70th Anniversary of the Department of Neurosurgery of Zürich Medical School".

Direct aneurysm surgery started more than 70 years ago. Introduction of cerebral angiography by Moniz in 20s and operating microscope by Yaşargil in 60s were the real cornerstones in vascular neurosurgery. Since then the development of neuroanestesiology and further development of non-invasive imaging (MRA and CTA) together with the latest development of operating microscopes with intraoperative ICG angio have shifted vascular microneurosurgery to a different level to still compete with the 'non-invasiness' of endovascular therapy.

Ultrasound image segmentation with shape priors: application to automatic cattle rib-eye area estimation.

Automatic ultrasound (US) image segmentation is a difficult task due to the quantity of noise present in the images and the lack of information in several zones produced by the acquisition conditions. In this paper, we propose a method that combines shape priors and image information to achieve this task. In particular, we introduce knowledge about the rib-eye shape using a set of images manually segmented by experts.

Surgical activity by Spanish Residents in Neurosurgery under the Training Programme in place since 1984 and changes to be implemented under the New Training Programme.

The Spanish National Committee for Neurosurgery has recently approved a new training programme which will shortly replace the former programme, which dates from 1984. The object of this report was to evaluate training in neurosurgery in Spain under the extant programme as perceived by the residents themselves. Assessment of any educational shortcomings might help in designing and evaluating the new one.

[Early prognosis in chronic subdural hematomas. Multivariate analysis of 137 cases].

Introduction: In the literature there is evidence relating different factors such as age and preoperative clinical condition with prognosis in patients treated surgically for chronic subdural haematoma.

Objective: To clarify and quantify the magnitude of the factors which determine early prognosis (during hospital admission) of these patients.

Patients And Methods: We made a prospective study of 137 patients who had been operated on in our centre and found the relationship between different clinical and therapeutic variables with the clinical course and morbidity-mortality by means of multivariate and survival analysis.
