This study was based on a survey of the death certificates of Pu-Li Town in Taiwan, issued over the past 20 years from 1966 to 1985. Age-adjusted mortality trends as well as cause-specific mortality trends were analyzed and compared with nationwide Taiwan data. As a whole, Pu-Li had a higher age-adjusted mortality than that of the overall Taiwan area. This finding may result from a higher mortality from tuberculosis in Pu-Li. Based on these data, the five leading causes of death in Pu-Li were cerebro-vascular disease, accident, heart disease, cancer and tuberculosis. Hypertension and diabetes were the 5th and 6th leading causes of death in 1985 and ranked 12th and 13th, respectively, in 1966. This data point out the increasing importance of hypertension and diabetes rates in Pu-Li. Tuberculosis and pneumonia had been controlled, ranking from the 1st and 3rd in 1966 to the 10th and 12th, respectively, in 1985. Suicide, cancer, and accident were usually coded as the single cause of death without other co-existent causes of death noted, so that there was in most instances not much difference between analyses based on the underlying cause of death and multiple causes of death. However, this was not true for hypertension and diabetes. If multiple causes of death were analyzed, only 34.5% of hypertension and 66% of diabetes were coded as the underlying cause of death. 37.2% of cerebro-vascular diseases co-existed with hypertension, and 20.3% of diabetes co-existed with hypertension.

Behind many clinical cases with recurrent, severe infections, absesses, delayed wound healing and especially in antibiotic resistant sepsis some granulocyte function abnormalities can be detected. The abnormalities are of inherited and acquired origin. The inherited dysfunctions are discussed here in details, but the appearance of some failures in neutrophil functions should be taken into consideration when examining patients with other diseases (e.g. diabetes, infections, periodontal disease, zinc deficiency, malignancies, uremia etc.). The main clinical tools for the diagnosis of the qualitative abnormalities in neutrophil functions are chemotaxis with migration, and an NBT test with and without stimulation, as a first indication. Any deviation in the result of these function tests requires further determinations.

Seventy-four cases of systemic listeriosis occurring from 1971 to 1989 in the greater Helsinki area in Finland are reviewed with a special interest in the effect of preceding immunosuppressive therapy on the clinical presentation. Of these patients, 66% had an underlying disease, most commonly malignancy, diabetes mellitus, or renal transplantation, and 43% had received immunosuppressive therapy within 1 week before onset of listeriosis. Bacteremia and central nervous system infections (both in 43% of cases) were the most common clinical entities. The percentage of patients with meningitis was not greater among immunosuppressed patients (13/32, 41%) than among patients with underlying diseases not treated with immunosuppressive agents (9/16, 56%) or among previously healthy nonpregnant hosts (7/11, 64%). Immunosuppressed patients did not die more frequently than did those with underlying diseases not treated with immunosuppressive therapy (case fatality rate, 29% vs. 38%, respectively). However, all previously healthy non-neonatal patients survived, whereas 32% (15/47) of those with any kind of underlying disease succumbed.

The pathogenesis of endometrial carcinoma, which is the most common malignant neoplasm of the female genital tract, is unknown. It is believed that a prolonged period of increased estrogenic exposure unopposed by progesterone may underlie the malignant transformation of the endometrial cells. In the following communication, we propose that deficient melatonin functions may be an additional endocrine factor implicated in the pathogenesis of endometrial carcinoma. This hypothesis is based on the observations that: (a) melatonin has antiestrogenic properties; (b) melatonin stimulates progesterone production which opposes the action of estrogens; (c) an increased rate of endometrial hyperplasia, a premalignant condition, has been noted during the winter, a time of year associated with diminished melatonin secretion; (d) an increased incidence of anovulatory cycles, which is a risk factor for endometrial carcinoma, occurs in the winter; (e) melatonin secretion decreases sharply during the menopause, a period associated with an increased risk of endometrial carcinoma; (f) obesity, which is a major risk factor for endometrial carcinoma, is associated with impaired circadian melatonin secretion; (g) diabetes mellitus, which is an additional risk factor for endometrial carcinoma, is associated with decreased melatonin secretion and an increased rate of pineal calcification; and (h) the prevalence of endometrial carcinoma is lower in the black population compared to the white population. Similarly, the incidence of pineal calcification, which reflects the secretory activity of the gland, is significantly lower in the African and American black populations as compared to the white population.(ABSTRACT TRUNCATED AT 250 WORDS)

The potential influence of postmenopausal estrogen therapy on the subsequent development of non-insulin-dependent diabetes mellitus (NIDDM) is relatively unexplored, despite postulated effects of these hormones on glucose tolerance. We examined the association between postmenopausal hormone use and the subsequent incidence of NIDDM in a prospective cohort of 21,028 postmenopausal US women aged 30 to 55 years and free of diagnosed diabetes, cardiovascular disease, and cancer in 1976. During 12 years of follow-up (422,991 person-years), we confirmed 1249 cases of NIDDM. Current users of postmenopausal hormones had a relative risk of NIDDM of 0.80 (95% confidence interval, 0.67 to 0.96) as compared with never users, after adjustment for age and body mass index (BMI). Past users of these hormones had an age- and BMI-adjusted relative risk of 1.07 (0.93 to 1.23). These results were not materially altered by multivariate adjustment for age, BMI, family history of diabetes, and coronary risk factors. Comparable results were obtained when the analysis was restricted to symptomatic NIDDM as the outcome. We observed no appreciable modification of these associations by family history of diabetes or category of BMI. Duration of current or past use of postmenopausal hormones and dose of conjugated estrogen were not significantly related to incidence of NIDDM. Type of hormone (estrogen alone, progesterone alone, or combination) also did not appear to influence NIDDM risk. These prospective data indicate that postmenopausal hormone therapy is unlikely to be associated with a material increase in the incidence of NIDDM among women.

Rapid economic development resulted in urbanization of Korea, since 1960s. Seoul is the center of politics, finance, education and culture of Korea. Mostly young people have migrated to large cities, such as Seoul and Pusan. For instance, the population in Seoul city was 2.5 million in 1960 but increased to 10 million in 1990. Presently, total population of Seoul and Pusan, second largest city, composed of approximately 50% of whole national population. The economic distribution among urban people became extremely uneven creating a large gap between low and high income group. As a consequence, both under and over nutritional problems coexist. According to the national nutrition survey data, animal food, such as meat, fish and dairy products have been consumed about 6 times more, and cereal consumption was far less in higher income group. In terms of nutrients intake, 28% of total caloric intake comes from lipids and 15-17% of total caloric intake from protein. This was found in higher income group, while low income group consumed more than 80% of total caloric intake from carbohydrate. The trends of major causes of death in Korea have changed. The degenerative diseases, cerebral disorder, high blood pressure became leading cause of death in recent years. Malignant neoplasm and diabetes followed second leading cause of death in Korea. Undernutrition and nutritional insufficiencies, anemia and low growth rate continue to exist among low income group. According to the annual death rate by age group, the age between 34-54 was the highest in the world.(ABSTRACT TRUNCATED AT 250 WORDS)

The effects of diabetes and insulin administration on certain aspects of phosphoinositide metabolism in R3230AC mammary tumors were studied in vivo. Three weeks after diabetes was induced by streptozotocin, [3H]myoinositol incorporation into PI, PIP and PIP2 was increased in R3230AC tumors, whereas the formation of [3H]IP, [3H]IP2 and [3H]IP3 was decreased. Administration of protamine zinc insulin (3IU, twice daily, for 3 days) to diabetic rats decreased [3H]myoinositol incorporation into phosphoinositides and inositol phosphates in these mammary tumors. The R3230AC tumor from insulin-treated diabetic hosts had lower levels of unmetabolized [3H]-myoinositol compared to tumors from diabetic animals. Enzymatically-dissociated tumor cells from insulin-treated animals displayed decreased myoinositol transport in vitro. These findings suggest that the insulin-induced decrease in the turnover of inositol lipids in vivo in R3230AC mammary tumors could have resulted from the decreased level of [3H]myoinositol in these cells.

Mortality data of Taiwan for 1981 through 1986 were analyzed using three different statistics in order to assess the role of environmental and lifestyle factors in causing mortality variations. Infant mortality rates from different geographic regions generally correlated well with overall mortality from all ages, suggesting that there are many common risk factors affecting the entire age range of the population. The mortality rates of tobacco- and alcohol-related causes of death and cancers were much higher in males than females. A number of cancer sites, including the lung, the liver, the stomach, and the nasopharynx, showed more than twofold excesses in males. In contrast, females had a tenfold excess of genital cancer and a 33% higher rate of diabetes. With rapid industrialization, occupational hazards played an increasing role in the development of cancer and other causes of death. During the study period, fishermen showed increased risk for cancers of the stomach, the esophagus, and the liver, while construction workers had an increased risk for cancer of the esophagus. Peasants and soldiers had an elevated suicide mortality. Among apprentices, fatal injuries were high. Findings from this study are useful in setting priorities for health and safety programs and directing efforts such as health education programs and other preventive strategies against disease.

50 patients with congenital rubella, born in 1939-43, were reviewed in 1967. Here we report their outcome in 1991. Since 1967, there have been 7 deaths (3 cardiovascular, 3 malignant disease, 1 AIDS). 40 had full clinical assessment. The prevalence of diabetes mellitus is similar to that in 1967: 4 of the 5 reported diabetic then, remain so, and there is 1 new case. 1 subject has malignant melanoma and 3 have died from cancer. Although the incidence of malignant disease is not increased, the death rate is (standardised mortality rate 6.0, 95% CI 1.24-17.57). Longer follow-up will be required to confirm this observation.

Women, like men, are susceptible to coronary atherosclerosis. Like men, more women die of heart disease than all forms of cancer combined. Coronary atherosclerosis is the result of the interplay of a number of factors, the most important of which are abnormal levels of circulating lipoproteins. As more has become known about the mechanisms by which abnormal levels of circulating lipoproteins promote atherosclerosis, certain risk factors have emerged as concerns for women, including: (1) diabetes mellitus as a risk factor, perhaps through its more profound effects on circulating lipoproteins; (2) serum triglyceride levels, and (3) changes in high-density lipoprotein cholesterol. The widespread use of exogenous hormones in women as both oral contraceptives and postmenopausal hormone replacement may also play a role in developing atherosclerosis. In general, estrogen affects circulating lipoprotein levels favorably, whereas progestins have the opposite effect. The effects of estrogen/progestin combinations in either oral contraceptives or postmenopausal hormone replacement will depend on the relative dose and potency of each of these constituents. Epidemiologic studies indicate that the use of oral contraceptives has no profound effect on the long-term risk of heart disease, whereas unopposed estrogen (without progestin) in postmenopausal hormone replacement therapy may lower that risk considerably. Recent U.S. and European guidelines for the detection, evaluation, and treatment of hypercholesterolemia in adults make it imperative that obstetrician-gynecologists, in their dual role as primary-care physicians and prescribers of exogenous hormones, be aware of and informed about the relationship between circulating lipids and lipoproteins and coronary heart disease in women.
