[High cord blood TSH in Morocco: iatrogenic hypothyroidism?].
A short prospective study was conducted to assess thyroid status in healthy full term newborns (n=90) of a large maternity of Marrakech (Morocco), as part of the validation of a national salt iodisation program. High TSH (>5mU/l) was detected in 89% of infants tested; urinary iodine excretion was measured in 35 of the mothers, and was found to be normal (100-200microg/l) or high (>200microg/l)(n=27) in all of them. Milk iodine concentration was measured in 315 lactating women from the same area. Low values (<41microg/l) were found in 60% of them. The common use of iodinated disinfectants during delivery could be responsible for the high urine iodine values of mothers; however iodine deficiency seems to remain a widespread problem in this population and justifies a large scale survey of iodine status.
