Two healthy male volunteers received 10 mg carbamazepine (CBZ) as a 2-h constant-rate intravenous (i.v.) infusion and 100 mg 15N-labeled CBZ as a 2% oral suspension, concomitantly. The two compounds have identical pharmacokinetics. Their respective concentrations in plasma were determined by gas chromatography-mass spectrometry (GC-MS) for 168 h. The comparison of the areas under the plasma curves (AUC) obtained by the two routes of administration, showed the systemic availability of CBZ given as an oral suspension to be equal to its availability when given intravenously. A two-compartment model was estimated: The apparent volume of distribution of CBZ at the steady-state (Vss) was approximately 1 L/kg.

[Prevalence of American trypanosomiasis, syphilis, toxoplasmosis, rubella, hepatitis B, hepatitis C, human immunodeficiency virus infection, assayed through serological tests among pregnant patients, from 1996 to 1998, at the Regional University Hospital Norte do Paraná].

In order to evaluate the seroprevalence of the american trypanosomiasis, syphilis, toxoplasmosis, rubella, hepatitis B infection, hepatitis C infection and human immunodeficiency virus infection among pregnant women attended at the Hospital Universitário Regional Norte do Paraná, Londrina State University, Paraná, a retrospective study of the serologic results performed in the prenatal routine during the period of June 1996 to June 1998 was carried out. The rates of seropositivity were as follows: american trypanosomiasis = 0.9%, syphilis = 1.6%, toxoplasmosis = 67% (IgG) and 1.8% (IgM), rubella = 89% (IgG) and 1.2% (IgM), hepatitis B surface antigen = 0.8%, hepatitis C virus = 0.8% and human immunodeficiency virus infection = 0.6%. An association between the increase in the seroprevalence of Chagas' disease and patient age was detected (p=0.006). The results underscore the importance of the serological tests in perinatal care, to prevent both the congenital and perinatally transmitted forms of theses infectious diseases.
