We examined body core and skin temperatures and thermal comfort in young Japanese women suffering from unusual coldness (C, n = 6). They were selected by interview asking whether they often felt severe coldness even in an air-conditioned environment (20-26 degrees C) and compared with women not suffering from coldness (N, n = 6). Experiments were conducted twice for each subject: 120-min exposure at 23.5 degrees C or 29.5 degrees C after a 40-min baseline at 29.5 degrees C. Mean skin temperature decreased (P < 0.05) from 33.6 +/- 0.1 degrees C (mean +/- SE) to 31.1 +/- 0.1 degrees C and from 33.5 +/- 0.1 degrees C to 31.1 +/- 0.1 degrees C in C and N during the 23.5 degrees C exposure. Fingertip temperature in C decreased more than in N (P < 0.05; from 35.2 +/- 0.1 degrees C to 23.6 +/- 0.2 degrees C and from 35.5 +/- 0.1 degrees C to 25.6 +/- 0.6 degrees C). Those temperatures during the 29.5 degrees C exposure remained at the baseline levels. Rectal temperature during the 23.5 degrees C exposure was maintained at the baseline level in both groups (from 36.9 +/- 0.2 degrees C to 36.8 +/- 0.1 degrees C and 37.1 +/- 0.1 degrees C to 37.0 +/- 0.1 degrees C in C and N). The rating scores of cold discomfort for both the body and extremities were greater (P < 0.05) in C than in N. Thus the augmented thermal sensitivity of the body to cold and activated vasoconstriction of the extremities during cold exposure could be the mechanism for the severe coldness felt in C.

Seven patients (one man and six women) with a diagnosis of pulmonary thromboembolism (PTE) were examined by polysomnography in order to clarify the relationship between sleeprelated breathing disorders and PTE. In the chronic stage of PTE, sleep apnea syndrome (SAS) was recognized in two patients (a man and a woman) among the subjects. Four of the five patients without SAS showed nocturnal hypoxemia. The female predominance was different from ordinary SAS without the disease background of PTE even though PTE is accompanied by hypoxemia and pulmonary hypertension like SAS. A pathophysiological relationship between PTE and SAS was not found in this study.

This is a case of a male infant who suffered from “Primary familial xanthomatosis with involvement and calcification of adrenals” (Wolman's disease). The clinical symptoms were characteristic hepatosplenomega‐ly, abdominal distention and a large amount of milky ascites. The patient died at the age of 2 1/2 months. X‐ray revealed enlarged, well‐shaped, calcified adrenal glands. Foamy cells in different organs which were observed at autopsy confirmed the diagnosis. On histochemical examination, deposition of a triglyceride‐cholesterol mixture was found in mesenchymal and epithelial cells of the liver, adrenals, spleen, lymph nodes and mucosa of the small intestine.
