Background: Growing evidence demonstrates the neuroprotective effects of statins, and the risk to develop an intracerebral hemorrhage (ICH) using statins has been refuted. However, some controversy remains regarding their role in the acute phase after ICH onset. Therefore, we performed a systematic review to investigate this issue.

Objectives: Throughout the world, 45 000 kidney transplants are performed per year. Graft and overall survival vary according to the type of donor (living or deceased donor). Anastomosis of a short renal vein with iliac vein or common external iliac vein has been associated with technical problems such as angulation of the vein or tension on the anastomosis, which could limit visualization and control of bleeding from the graft.

Object: The favorable effect of statin treatment after traumatic brain injury (TBI) has been shown in animal studies and is probably true in humans as well. The objective of this study was to determine whether acute statin treatment following TBI could reduce inflammatory cytokines and improve functional outcomes in humans.

Methods: The authors performed a double-blind randomized clinical trial in patients with moderate to severe TBI.

Background: Toxic or fulminant colitis due to Entamoeba histolytica infrequently presents but is very serious. Unfortunately, there are numerous contradictory factors related to mortality.

Methods: We analyzed several cases of E.

Objectives: To identify the variables that predict the failure to treat amoebic liver abscesses.

Methods: We prospectively carried out a case-control study on a cohort of patients who had been diagnosed with amoebic liver abscesses using clinical, ultrasonic, and serologic methods. Patients with pyogenic abscesses, negative ELISA tests for amoebiasis, immunosuppression status, or previous abdominal surgery were excluded.

Objective: To propose a scoring system using endoscopy for assessment of the inflammatory alterations caused by neurocysticercosis (NCC) inside the ventricular cavities and the basal subarachnoid space.

Methods: Video recordings of the endoscopic procedures in patients with hydrocephalus secondary to NCC were assessed in a two-phase study. In the first phase (n = 10), the assigned score of each patient was correlated with the cerebrospinal fluid values obtained by lumbar and ventricular puncture.

Introduction: The spontaneous intracerebral hemorrhage (ICH) shows a high lethal rate. In 1999 appeared the first therapeutic guidelines, after that new therapies have been assessed without substantial success.

Aim: To describe treatment changes for ICH in a regional Mexican hospital and to assess their impact on clinical evolution.

Objective: Hydrocephalus due to neurocysticercosis usually shows poor prognosis and shunt failure is a common complication. Neuroendoscopy has been suggested as treatment, but the indications remain unclear.

Methods: A cohort of patients with clinical/radiological diagnosis of hydrocephalus due to NCC, treated between January 2002 and September 2006, were the subjects of the study.

Background: Compare the differences between proteins, glucose, and morphological cellular counts from ventricular cerebrospinal fluid obtained by neuroendoscopy and lumbar puncture.

Methods: This was a retrospective, transversal study. From January 2003 until June 2006, 30 neuroendoscopies were performed on patients with hydrocephalus secondary to NCC.

Amnesia is a common sequela following traumatic brain injury (TBI), for which there is no current treatment. Pleiotropic effects of statins have demonstrated faster recovery of spatial memory after TBI in animals. We conducted a double-blind randomized clinical trial add-on of patients with TBI (16-50 years of age), with Glasgow Coma Scale (GCS) scores of 9-13, and intracranial lesions as demonstrated by computed tomography (CT) scan.

Introduction: To identify the laboratory and ultrasound factors that could predict the response to medical treatment of amoebic liver abscess.

Material And Method: Retrospective study of patients diagnosis with amoebic liver abscess in Hospital Central in San Luis Potosí, Mexico. We included patients greater than 15 years of both sexes.

Dental caries is a worldwide public health problem for which Streptococcus mutans has been identified as the possible infectious etiology. In recent years nanotechnology has permitted the development of new properties of materials. The objective of this study was to compare the bactericidal and bacteriostatic effects of nanoparticles of silver, zinc oxide, and gold on S.

Introduction: The transplantation program of organs obtained from deceased donors requires a complex structural organization. Medical, logistic, and cultural aspects must be taken into account.

Material And Methods: We analyzed the detection of possible organ donors in San Luis Potosí, Mexico, from August 21, 1999 to August 30, 2002.
