Comparison of cerebrospinal fluid obtained by ventricular endoscopy and by lumbar puncture in patients with hydrocephalus secondary to neurocysticercosis.

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.

Peginterferon alpha-2a and ribavirin versus peginterferon alpha-2a monotherapy in early virological responders and peginterferon alpha-2a and ribavirin versus peginterferon alpha-2a, ribavirin and amantadine triple therapy in early virological nonresponders: the SMIEC II trial in naïve patients with chronic hepatitis C.

Objective: The objective of this study was to compare the efficacy of anti-hepatitis C virus (anti-HCV) treatment schedules on the basis of an early virological response (EVR), defined as undetectable serum HCV-RNA (<50 IU/ml) after a 12-week induction course of peginterferon alpha-2a (PEG-IFN) 180 mcg/week.

Methods: A total of 210 interferon-naïve patients (69% male; median age, 42 years) with histologically proven chronic hepatitis C infection (genotype 1: 62%) received PEG-IFN 180 mcg/week for 12 weeks. Patients with EVR (58%) were randomized to continue PEG-IFN monotherapy (n=64) or to add ribavirin (RBV), 800 mg/day (n=57), for 36 additional weeks.
