Objective: To compare the standard cervical cancer screening procedure--the Papanicolaou test or Pap smear--with detection through visual inspection using acetic acid (VIA), and visual inspection with acetic acid assisted by Aviscope (VIAM).
Material And Methods: The study was conducted between October 1998 and December 2000, in two Mixteca regions in Oaxaca, Mexico. A field trial design was used to randomize the two regions to either of the two inspection methods.
Objective: To establish the relation between maternal blood lead (MBL) and umbilical cord blood lead (CBL) levels during delivery, and to determine the major predictors for MBL in women covered by the Mexican Institute of Social Security (MISS), in Mexico City.
Material And Methods: From 1991 to 1993, a cross-sectional study was conducted in four MISS hospitals, among normal pregnant women who volunteered to participate. Blood samples were taken from women and from the umbilical cord during delivery.
Objective: To evaluate the diagnostic precision of the cervical cytology (smear) in a sample of 16 cervical cancer screening centers (CCSCs) from the Mexican Ministry of Health and Mexican Institute for Social Security CCSCs distributed across the country.
Study Design: Each center received a batch of 90 cytologic specimens with a random positive prevalence of 1.5-36%.
