[Chronic autoimmune thyroiditis in the child].
OBJECTIVE: The aim of the study was to describe the clinical characteristics and long-term follow-up of a group of children with chronic autoimmune thyroiditis. PATIENTS AND METHODS: Sixty children (age: 11.9 +/- 2.7 years) were studied in a retrospective analysis. RESULTS: At diagnosis, 34 of the children were hypothyroid (compensated hypothyroidism, n = 15; true hypothyroidism, n = 19) and 26 euthyroid. Thyroid ultrasonography showed characteristic features of heterogenicity and/or hypoechogenicity in all patients. Other autoimmune diseases were found in ten subjects (17%) and 23% had a family history of thyroid disease. At the end of the follow-up, nine of 45 children (20% of the cases) followed up for at least one year (mean follow-up 4.4 +/- 3.7 years), demonstrated a change in thyroid function. Hypothyroidism was detected in two initially euthyroid patients. Among initially hypothyroid patients, seven (28%) recovered normal thyroid function, allowing L-thyroxine withdrawal for four weeks, after 1.5 to 8.4 years. No factor was found to be predictive of the course of the disease. All subjects treated with L-thyroxine for hypothyroidism reached normal final height. CONCLUSION: The natural course of chronic lymphocytic thyroiditis is variable and unpredictable. Recovery from hypothyroidism does occur and can be aided by the L-thyroxine withdrawal test. The disease requires lifelong thyroid surveillance, especially in women during pregnancy, in order to avoid a potential adverse effect on the future child.

Placental alterations, intrauterine growth retardation and teratogenicity associated with enalapril use in pregnant rats.
Enalapril (15 mg/kg/day p.o.) was given to 11 pregnant rats from day 1 to 9 (E1-9) and to 11 rats from day 10 to 20 (E10-20) of pregnancy; 12 rats were the control group. Fifteen animals were sacrificed on day 20 of pregnancy and 19 were allowed to progress into partum. Placentas were smaller in E10-20 rats (-15%, p less than 0.05) and had a simple hypocellular cordonal structure; in E1-9 animals the predominant pattern was a combination of complex and simple structure. At day 20 the fetuses in the treated groups were smaller than the controls (-5% in E1-9 and -16% in E10-20, p less than 0.05); differences disappeared on the 13th day postpartum. Two fetuses from treated mothers presented incomplete skull ossification. We believe this report adds arguments to preclude converting enzyme inhibitors in pregnancy.
