ABSTRACT
Carbamazepine-induced hyponatremia has been reported in 21.7% of 61 patients with mental retardation who received the medication for a variety of reasons. We studied 40 patients with mental retardation receiving carbamazepine to determine the prevalence of hyponatremia. Overall, hyponatremia was found in only 5.0% of these patients. Correlations with sodium level and carbamazepine dose, serum drug level, and concomitant neuroleptic and anticonvulsant polytherapy were also examined. Treatment with carbamazepine resulted in a statistically, but not clinically, significant decrease in serum sodium levels in patients receiving anticonvulsant polytherapy. Decreases in serum sodium were not related to carbamazepine dose or blood levels. Only one patient with underlying schizophrenia and psychogenic polydipsia demonstrated clinically significant hyponatremia during carbamazepine therapy.

A group of 138 community-based patients with Down syndrome were examined for evidence of autoimmune thyroid dysfunction at the time of their referral for routine health care services provided as part of a model program. Twenty-eight patients (20.3%) were found to have previously unrecognized hypothyroidism, and 2 patients (1.4%) had previously unrecognized hyperthyroidism. In addition, 66 patients were tested for thyroid autoantibodies, and 26 were found to have positive antimicrosomal and/or antithyroglobulin antibody test results. There was no statistically significant association between age or sex and the mean thyrotropin value or the presence of thyroid autoantibodies. The relationship between the mean thyroxine level and sex was mildly significant. Of the patients with hypothyroidism, 78.5% were female, and most were between the ages of 30 and 50 years. However, a higher-than-expected number of patients with autoimmune hypothyroidism were under age 30 years. These findings highlight the lack of adequate health care services available to persons with Down syndrome who live in the community. All persons with Down syndrome must undergo regular clinical and laboratory screening for the presence of thyroid disease.

Persons with developmental disabilities living in the community have a greater number and variety of health care needs than the average population of the same age and sex. The erroneous assumption that the generic health care system would be able to provide all necessary services to the large number of individuals recently transferred from state residential facilities to the community has proved to be an unexpected disappointment to human service policymakers. In an effort to remedy this situation, a program of health care services was established by the New Jersey Department of Human Services at a community teaching hospital to supplement the existing generic system of medical care. Within four years, the program had rapidly grown to provide care for 729 patients who had come to rely on the center for primary care, specialty medical and dental services, and medical case management. The demographic characteristics of this program are described as well as data on morbidity, service utilization, and special problems encountered when care was provided to this complex and medically underserved population.
