Lessons about the reliability of congenital syphilis and vertical HIV transmission data learned from case reviews in Uruguay: a cross-sectional study.

Background: In Uruguay it is mandatory to review all cases of positive HIV or reactive syphilis tests in pregnancy and peripartum. We compared the rates of mother-to-child transmission of syphilis and HIV detected by case reviews to those obtained from the usual surveillance system and described the characteristic of vertical transmission cases.

Methods: This is a cross-sectional study performed with secondary data obtained from official government sources, for all the country cases of maternal to child transmission of HIV and syphilis from 2012 to 2017, with descriptive analyses.

[Cryptococcus neoformans meningitis in children and adolescents infected with HIV].

Three cases of meningitis due to criptococcus in children infected with HIV are reported. All patients had severe immunodeficiency. The first case occurred before antiretroviral therapy.

Prospective multinational study of pertussis infection in hospitalized infants and their household contacts.

Background: Increased incidence of pertussis has been noted among infants too young to be immunized. We studied the disease burden of pertussis in pediatric intensive care units and the source of infection in several Asian, European and Latin American countries.

Methods: The study was conducted in 7 countries from September 2001 to January 2004.

[Detection of HIV infection in pregnant women by rapid testing: a successful strategy to reduce its vertical transmission].

Unlabelled: A high percentage of Uruguayan pregnant women are not under medical control. As a consequence, vertically transmission of HIV infection reaches to 50%. The aim of this study was to know the prevalence of HIV infection in pregnant women who did not know their serological status and to decrease mother-to-child transmission.
