A case-control study of endometrial cancer in relation to reproductive, somatometric, and life-style variables.

A hospital-based case-control study of cancer of the endometrium was conducted in Athens, Greece, from 1992 to 1994. The cases were 145 women residents of Greater Athens with histologically confirmed incident cancer of the endometrium, operated in the two cancer hospitals of the Greater Athens area or the major University Department of Obstetrics and Gynecology. Controls were 298 women residents of Greater Athens hospitalized for bone fractures or other orthopedic conditions in the accident hospital of Greater Athens. The data were analyzed by modeling through multiple logistic regression. The risk of endometrial cancer decreased with the number of livebirths (p for trend < 0.01), with early age at menopause (p = 0.03), and with later age at menarche (p = 0.11), whereas miscarriages and induced abortions were clearly unrelated. There were nonsignificant relations of disease risk with smoking (inverse), alcohol (inverse), and menopausal estrogens (positive), whereas oral contraceptive use was too uncommon to allow meaningful study. The lower risk of the disease associated with current occupations requiring manual activity (p = 0.03) and the lower, although not significantly so (p = 0.36), energy intake of cases in comparison to controls suggest that physical inactivity could be an important risk factor for endometrial cancer. Women with endometrial cancer were significantly taller than control women (p = 0.02). The latter results indicate that excess energy intake in early life, leading to higher attained stature, and excessive energy intake in later life, on account of physical inactivity and leading to higher body weight, converge in increasing the risk for endometrial cancer.

Serum steroids in relation to benign prostatic hyperplasia.

In order to investigate the endocrine etiology of benign prostatic hyperplasia (BPH), we conducted a case-control study in Athens, Greece using 52 patients with histologically confirmed BPH and 52 healthy controls matched according to age and town of residence. Blood samples were collected from all participants and analyzed blindly in Boston, Mass. regarding testosterone (T), dihydrotestosterone, estradiol (E2), sex hormone-binding globulin, and dehydroepiandrosterone sulfate (DHEAS). Results from logistic regression models, adjusting for age, height, body mass index, years of schooling, and mutually among the measured hormones, indicate that DHEAS is significantly positively associated with the risk of BPH [odds ratio = 3.10 per standard deviation (60 micrograms/dl), 95% confidence interval (1.28,7.50)]. T and E2 were not significantly related to the risk of BPH.

Birth size and neonatal levels of major components of the IGF system: implications for later risk of cancer.

Pre- and perinatal conditions and processes may affect the risk for some forms of cancer in later life, while the insulin-like growth factor (IGF) system may play a role in both early somatic growth and later carcinogenesis. Birth weight and length, and the variation of major components of the IGF system immediately after birth, were analyzed in relation to selected physiological and pathological variables. The study comprised 331 healthy full-term newborns from whom blood samples were taken during routine phlebotomy no later than the fifth day of life. Measurements of IGF-I, IGF-II and IGF-binding protein-3 concentrations were performed. Birth length and weight were measured and information on socio-economic and medical variables was recorded. The concentrations of all three proteins were lower when blood bilirubin levels were high, possibly as a result of compromised liver function and/or as a component of an activated acute phase reaction. Birth weight was significantly higher by about 46 g among children whose IGF-I was higher by one SD, while the associations of birth weight and length with other components of the IGF system were in the predicted directions, albeit only in trend. We conclude that in early life, growth is related to the IGF system, mostly IGF-I. The latter is lower in children with jaundice, possibly because of hepatic dysfunction and/or as part of an acute phase reaction. We speculate that elevations of IGF-I in early life might explain the increased risk of cancer in individuals born with a higher birth weight.

Cellular immunity in patients with leprosy. Circulating T lymphocytes and their response to PHA in leprosy.

The ability of peripheral blood lymphocytes from polar lepromatous (LL), borderline lepromatous (BL) and borderline tuberculoid (BT) patients to transform in vitro in the presence of phytohemagglutinin was found to be significantly reduced. A significant reduction in the percentage and absolute number of T lymphocytes was observed in LL cases. In BL cases the number of T lymphocytes was decreased, but the reduction was proportional to the reduction in the total lymphocyte population was observed only in bacteriologically positive cases.

[A new procedure of "Salmonella" enrichment (author's transl)].

We have prepared a modification of Rappaport's medium by reducing the content of themalachite green oxalate: medium R10, which is incubated at 43 degrees C instead of 37 degrees. These two modifications allow a satisfactory growth of a wide range of Salmonella and a better inhibition of competing organisms than the original medium of Rappaport incubated at 37 degrees and than Muller-Kauffmann's medium incubated at 43 degrees.
