A neuropsychological study comparing patients infected with HCV and HBV without psychiatric comorbidities.

Hepatitis C is one of the most common chronic infectious diseases worldwide, with well-documented extra-hepatic manifestations, such as a broad number of cognitive deficits. These impairments may be explained by psychiatric comorbidities, which have not been investigated properly in the literature. In order to elucidate a specific hepatitis C virus (HCV) induced cognitive impairment not related to mental disorders, neuropsychological performance of patients infected with HCV was compared with that of patients infected with hepatitis B virus cognitive impairment, especially psychiatric comorbidities.

[Birth weight as predictor for the severity of neonatal brain white matter lesion].

To analyze the association of natal factors with the severity of neonatal brain white matter lesion (WML) by controlling the birth weight, we identified newborns with WML who were divided into: those with WML evolution towards resolution of the ultrasound image (less severe), and those who evolved with cist formation and/or ventriculomegalia and/or hemorrhage (greater severity). There were differences among the twelve variables (hyponatremia, anemia, infection, retinopathy, broncopulmonary dysplasia, hypoalbuminemia, persistence of the arterial canal, altered audiometry, early respiratory distress, birth weigh below 2,500 g, weight per category, and prematurity) between the two groups (p<0.05), being that nine variables (hyponatremia, infection, retinopathy, hypoalbuminemia, persistence of the arterial canal, early respiratory distress, low weight, prematurity, and weight per category) remained statistically different (p<0.
