Hypothyroidism in an area of endemic goiter and cretinism in Central Java, Indonesia.

In an area of severe endemic goiter in Central Java, Indonesia, clinical overt or mild hypothyroidism appeared to be present in 7 out of 20 cretins and also in 12 out of 94 non-cretinous subjects, all 5-20 years of age, living in the village of Sengi. Hypothyroidism was not found in a control group of 70 subjects of the same age living in Londjong just outside the edemia. In hypothyroid subjects the plasma PBI-concentration was 0.98+/-0.32 mug/100 ml (mean+/-SD) vs. 2.72+/-1.24 mug/100 ml in euthyroid subjects from Sengi and 4.86+/-0.80 mug/100 ml in controls from Londjong. Values for T3 were 56.3+/-3.17 ng/100 ml in hypothyroids, 140.5+/-38.5 ng/100 ml in euthyroids from Sengi and 121.6+/-27.4 ng/100 ml in controls. The TSH levels (geometric mean and range) in these 3 groups were, respectively, 210.1 (108.0-342), 15.6 (3.0-372) and 4.1 (0.8-7.0) muU/ml. The differences between the mean concentration of PBI, T3 and TSH in the hypothyroid and euthyroid groups were highly significant (P less than 0.001). These data strengthen the clinical diagnosis of hypothyroidism in cretins as well as in non-cretinous subjects. All hypothyroid subjects had a PBI less than 1.8 mug/100 ml and T3 less than 120 ng/100 ml and TSH greater than 100 muU/ml. In 8 hypothyroid subjects, restudied 18 months after iodized oil injection, hypothyroidism was either corrected or markedly improved. It therefore appears that iodine deficiency per se in postnatal life may lead to (juvenile) hypothyroidism, which can be corrected by iodine therapy. Our findings have implications for the definition and diagnosis of endemic cretinism. Not all hypothyroid subjects in an area of endemic iodine deficiency should be classified as cretins.

Studies on hearing loss in a community with endemic cretinism in Central Java, Indonesia.

An audiometric study was carried out in a community of 642 subjects severly affected by endemic goitre and cretinism. Hearing loss was measured in 34 out of 41 subjects diagnosed as cretins, 92 normal subjects aged 5-20 years from the same community and 54 subjects (also of 5-20 years) living in a nearby control area without endemic goitre. The excess number of hearing defects in the endemic area seems to be entirely due to the process that leads to cretinism. There is no reason to describe deafness and deafmutism in an area with severe endemic goitre as a separate entity. The hearing defect showed a definite greater loss in the higher frequencies than in the lower frequencies and was found in 92% of the cretins. Deafmutism was present in 5, a loss of more than 60 db in 8, a loss of 40-60 db in 10 cretins. A loss of 20-30 db was found in 2.2% of normal subjects in the endemic area and 1.8% of those living in the control area. It is concluded that audiometry is a simple and significant test to establish the presence of the neurological form of endemic cretinism, which is the most prevalent form in most endemias. The differential diagnosis and pathogenesis of the described hearing defect are discussed.
