Abstract PDF: Pregnancy in acromegaly is very rare. Amenorrhea and infertility are common manifestations in acromegaly. The pregnancy may be influenced by acromegaly in many ways and pregnancy itself may influence the course of a pituitary tumor. We report of a case of pregnancy in a woman who was diagnosed with acromegaly during the course of pregnancy. Her pregnancy was uneventful and she delivered a healthy baby at 38 weeks by cesarean section. No treatment was undertaken during the pregnancy and transsphenoidal surgery was performed after the delivery.

Abstract PDF: BACKGROUND
Leptin has been reported to be correlated with the amount of adipose tissue in humans. The plasma leptin concentrations were not different between diabetics and non-diabetics in Mexican-Americans; however, the leptin might stimulate or diminish insulin secretion and induce insulin resistance. Then, it can be postulated that leptin may one of the key factors in the development of insulin resistance. Therefore we were to note any differences in FPL (fasting plasma leptin levels) between diabetics and normal subjects, and to investigate variables such as PBF (percentage body fat), BMI (body mass index), FPI (fasting plasma insulin) to determine their effects on the variation of FPL. We also were to investigate whether FPL influenced the GUR (glucose utilization rate). METHODS: The subjects were 116 type 2 diabetics and 45 normal subjects in Korean. PBF, BMI, WHR (waist hip ratio) were measured. Fasting plasma insulin and leptin levels were measured by radioimmunoassay. Euglycemic and/or hyperglycemic clamp tests were performed in 19 diabetics and 16 normal subjects. RESULTS: 1. There was no difference in FPL between diabetics and normal subjects. 2. A significant difference was found in FPL between female and male subjects. 3. Gender and body composition such as PBF, BMI contributed plasma leptin levels. 4. FPL was associated with GUR (Insulin resiatance) only in male subjects. 5. During 2h clamp tests, the acute increments of insulin or glucose did not change the leptin levels. CONCLUSION: These data suggested that there was no difference in FPL between diabetics and normal subjects, whereas gender, body composition such as PBF, BMI contributed leptin levels.

Abstract PDF: Recently it is known that Turner's syndrome is frequently associated with hypothyroidism. We report a case of Turner's syndrome associated with subclinical hypothyroidism. A 23-year-old female was admitted to the hospital with complaints of amenorrhea and short stature. She had a mosaicism of 45, X0/46, Xi(X_q) in the cell, cultured from the peripheral blood. The plasma thyroxine and triiodothyronine were normal and there was no clinical symptom of hypothyroidism. But the thyroid-stimulating hormone(TSH) concentration was unusually higher(184 uU/L). She has been treated with the cyclic therapy of conjugated estrogen and medroxyprogesterone, in addition to the thyroxine replacement therapy. After 2 months, the menstruation was restored and TSH was normalized.
