[Health trajectories of women who used cocaine and/or cannabis during pregnancy. Retrospective cohort study in La Pampa, Argentina].

Introduction: the use of cocaine and cannabis during pregnancy is a growing problem, of importance for the World Public Health. Women can present a wide range of complications during pregnancy and perinatally, although knowledge about evolution thereafter is scarce.

Objectives: to describe and compare health trajectories up to 4 years pospartum of user and not user women of cocaine and/or cannabis during pregnancy.

Four-year health trajectories of children prenatally exposed to cocaine and/or cannabis. A retrospective, cohort study in La Pampa, Argentina.

Introduction: Cocaine and/or cannabis use during pregnancy is a growing problem of relevance for global public health. Exposed children may have a wide range of perinatal complications, but there is little knowledge on their course.

Objective: To describe and compare the health trajectories of children prenatally exposed and unexposed to cocaine and/or cannabis over 4 years.

Low iodine intake during pregnancy: relationship to placental development and head circumference in newborn.

Introduction: Iodine is considered to be an essential micronutrient in pregnant women. Iodine placental transport to the embryo-fetus is essential for hormone synthesis and is crucial for nervous system development. However, the relationship between iodine intake and placental weight and its potential implications for the newborn have not been studied.

[An approach to a sanitary and social problem: urinary iodine excretion in pregnant women from a iodine deficient region].

The urinary iodine excretion (UIE) assay is an effective method to detect reduced iodine intake. UIE was measured in two different samples (morning and evening) from 121 pregnant women, with a turbid-metric method modified by Pino (normal value =150 ugl/1). Furthermore, thyroid function was evaluated in pregnant women with UIE <100 ug/l.
