Lissencephaly (agyria) on computed tomography.

Unusual computed tomographic findings were observed in two infants with similar clinical pictures including delay in developmental milestones, seizures, decerebrated posture, and microcephaly. Computed tomography revealed small brain with widened subarachnoid space, smooth surface of the brain, uniformly enlarged ventricles, wide sylvian cisterns, and lack of insular opercularization. These findings coincide with pathologic features of lissencephaly (agyria), a rare congenital anomaly of the brain due to interruption of neuronal migration.

Changes of urinary cyclic AMP excretion and plasma parathyroid hormone levels before and after parathyroidectomy in patients with primary hyperparathyroidism.

Urinary cyclic AMP excretion and plasma parathyroid hormone(PTH) levels were examined in three patients with primary hyperparathyroidism before and after parathyroidectomy. Plasma PTH and urinary cyclic AMP in the individual patients decreased in parallel following parathyroidectomy. During surgery there was a statistically significant correlation between PTH levels and cyclic AMP excretion in individual patients. These findings support the claim that the rate of urinary cyclic AMP excretion reflects endogenous PTH activity in patients with primary hyperparathyroidism.

Hepatocellular carcinoma associated with erythrocytosis. A nine year survival after successful chemotherapy and left lateral hepatectomy.

A case of hepatocellular carcinoma associated with erythrocytosis is described. The patient was successfully treated with a combination chemotherapy of 5-fluorouracil, mitomycin C, cyclophosphamide and chromomycin A3, which was followed by a left lateral hepatectomy, and has survived for more than 9 years after the operation without any signs of recurrence. With the regression of hepatic tumor by the anticancer chemotherapy, the remission of erythrocytosis was observed, indicating that the tumor was producing erythropoietin. The data suggest also that erythrocytosis could be a marker for evaluation of chemotherapeutic effects in some patients with hepatocellular carcinoma.

Psychosomatic aspects of the effect of conjugated estrogens in patients with postoperative ovarian deficiency syndrome.

Fifty-three uterine cancer patients who complained of the syndrome dur to vasomotor manifestations or psychosomatic response after ovariectomy were given Premarin tablets, 1.25 mg per day or placebo for 3 weeks and improvement in their complaints was compared from the psychosomatic aspects by the double-blind method. Premarin was significantly more effective than placebo (P less than 0.001) in the psychologically normal patients. On the other hand, no difference in the effectiveness of these drugs were found in the psychologically abnormal patients (P = 0.119). According to the self evaluation by the patients, Premarin was significantly more effective than placebo (P less than 0.05) in the psychologically normal patients. However, there was no difference in the effects of these agents in the psychologically abnormal patients.

LBA technique in the detection of chromosome variants. I. Chromosomes with known sites of Q variants.

A method is described (LBA method) which used DNA replication pattern in the detection of chromosome variants in man. In Part I, results on chromosomes with known sites of Q-variants, i.e., 5 pairs of acrocentrics, as well as 3 and 4, were presented. Fourty-one variants were detected in a total of 40 acrocentrics. Twenty-eight of them were detected only by the LBA technique; 11 of them being in short arms and 17 of them in centromeres. Seven variants, including 4 of those in satellites, were detected only in QFQ-stained metaphases. Six short-arm variants were observed by both methods. It appears that a sequential QFQ-LBA technique is very useful in the detection of variants in D- or G-group chromosomes.

A case of (13q;18q) translocation with proximal 13q monosomy.

A case of partial monosomy of the 13p terminal to 13q12, associated with a de novo 13/18 translocation, is reported. The symptoms appeared to be derived from both 18q- and partial monosomy 13, the latter giving rise to: high arched palate, epicanthus, antimongolian slant, small eye fissure, flat nasal bridge, hypoplastic helix, and large clitoris. Serum Ig-A and Ig-M levels were normal in our case.
