Congenital dyserythropoietic anemia type I: report of a pair of siblings in Japan.

This is the first case of two siblings with congenital dyserythrobpoietic anemia (CDA) type I to be reported from a Japanese family. Both of these cases showed characteristic morphological aberration of erythroid precursors, ineffective erythropoiesis, and negative acidified serum test. The ultrastructural study of erythroblasts also revealed characteristics quite compatible with CDA type I.

[Polyuria and polydipsia in a young boy--a case study (author's transl)].

A 13-year-old boy with a teratoma in the sellar region was presented. This patient had gradually developed polyuria and polydipsia since 2 years prior to the first admission. Endocrinological examination showed a marked reduction of pituitary function. Careful neuroradiological examinations including CT failed to show any mass lesion in the sellar and suprasellar regions but a marked increase of the width of the third ventricle. CSF examination revealed only a slight increase of cell count (lymphocytes). The patient was discharged with hormonal replacement therapy. Seven months later the patient developed visual disturbance and mental disorders. On the second admission, plain skull films showed enlarged sella and CT demonstrated a mass in the suprasellar region. Preoperative diagnosis was suprasellar germinoma. At surgery a teratoma, probably arising from the pituitary fossa, was totally removed. Histopathology of the tumor showed tri-dermal tissues including melanotic progonoma and germinoma. The authors presented various problems of the patient and their solving processes.

[Relation of TRH test to thyroidal suppression test by triiodothyronine in patients with hyperthyroidism under treatment with antithyroid drugs (author's transl)].

The relation of the TRH test to the T3 suppression test was investigated in 43 patients with hyperthyroidism receiving antithyroid drugs for 6 to 27 months (average 14 months). TRH tests were performed by measuring serum TSH levels before and 15, 30, 45, 60, 90 and 120 minutes after intravenous injection of 500 mug of synthetic TRH. Serum TSH was measured by a double antibody radioimmunoassay. Two weeks later, the T3 suppression test was performed by measuring the 24-hr thyroidal uptake of radioiodine after daily administrations of 75 mug of triiodothyronine for 8 days. All patients under study were in euthyroid state, estimated by serum T3-RSU, T4, T3 and FT4I. The value for 24-h uptake after T3 administration was less than 20% in 18 cases, out of which the response to TRH was normal or exaggerated in 15 cases and was absent or impaired in 3 cases. On the other hand, out of 25 cases with the value of 24-h uptake more than 20%, the response to TRH was absent or impaired in 18 cases and was normal or exaggerated in 7 cases. The results of the TRH test and the T3 suppression test were correlated in 33 out of 43 cases. The responsiveness to TRH and the suppressibility with T3 was dissociated in 10 cases, suggesting the TRH test could not replace the T3 suppression test.
