A 68-year-old man with hypertension was admitted to the Shiga Kenritsu Seijinbyo Center for further examinations, because abnormal opacity in the right upper lung field was accidentally revealed by chest X-ray. Chest CT demonstrated two separate mass shadows, one 31 X 27 mm, the other 10 X 10 mm in size, both of which were located in the posterior segment of right lung. Specimens from transbronchial biopsy of the larger mass was histologically diagnosed as adenocarcinoma. He underwent right upper lobectomy with hilar and mediastinal lymph nodes resections. Postoperative patho-histological study showed the larger mass to be poorly differentiated adenocarcinoma, the smaller one, small cell carcinoma respectively, and no continuity between the two masses. Lymph nodes metastasis were negative. Any malignancy was not detected by brain CT, abdominal CT and any other gastro-intestinal examinations, and he was diagnosed to have double primary lung cancers in the same one segment. In this report, we discussed the diagnosis and treatment of double primary lung cancers, and reviewed the literatures.

Confirmation of a causal relationship between hemolytic-uremic syndrome (HUS) and verotoxin-producing Escherichia coli (VTEC) infection is provided by the case of a 22-year-old West German woman. The patient presented with fatigue, nausea, and headache. Ultrasonography revealed enlarged kidneys, and laboratory investigations showed uremia, hemolytic anemia, lactate dehydrogenase, haptoglobin below the detection limit, and thrombocytopenia. She received hemodialysis and drug treatment (heparin, dopamine, and furosemide). To investigate the kinetics of the humoral response to verotoxin, the patient was followed for 3 months. Fecal specimens on day 23 yielded E coli serotype 0111:NM, and stool filtrates on days 16 and 23 showed highly cytotoxic activity for HeLa cells. While the patient's initial serum showed a high IgM immune response against purified Shiga toxin, there was a steady decline in IgM and steady increase in IgG antibodies over the ensuing 3 months. These findings are suggestive of a recent infection by a verotoxin-producing organism. This is the 1st reported case of VTEC-associated HUS with e coli 0111 infection in an adult, and the patient's 4-year history of oral contraceptives (OCs)--ethinyl estradiol and chlormadinoneacetate--is considered to be of etiologic significance. The diminished antibody coating of bacteria in the urinary tract of OC users may have facilitated invasion of verotoxin across the mucosal barrier in this patient. Severe hypertension has been reported previously in OC users with HUS. It is speculated that verotoxin may trigger HUS in longterm OC users, initiating vasoconstriction and microangiopathic hemolysis.

Among the 47 prefectures of Japan, the prefecture of Shiga stands out due to its remarkably high death rate from diabetes, especially in female diabetics. In an attempt to clarify the causes, a diabetes detection study was carried out in the inhabitants aged 40 or over of five communities. The prevalence rate of diabetes was 1.7%; male 2.5% and female 1.3%. However, the study could include only 14% of the inhabitants (3253 out of 23,249 inhabitants). In a community named Aito, where the diabetic death rate was the highest among communities of the prefecture and the study covered 95% of the 1849 inhabitants, the prevalence of diabetes was 3.0% in males and 1.2% in females (2.2% in total). Obesity, hypertension and ischemic change in electrocardiogram were more frequent in female diabetics than in male diabetics in this community. These results suggest that the high death rate from diabetes in the female population is not caused by a high prevalence rate of diabetes and female diabetics may be affected by several risk factors which influence their prognosis more often than that of male diabetics.

Obesity is considered to be one of the major risk factors for developing non-insulin dependent diabetes mellitus (NIDDM). Our cohort study for NIDDM in Aito, Shiga 1980-1990 confirmed that aging, higher body mass index (obesity) and high blood pressure were independent risk factors for developing NIDDM in Japan. In Pima Indians, decreased glucose disposal rate (GDR) is significantly related to percentage of body fat (%fat). Insulin signaling for glycogen synthesis in the skeletal muscles is impaired in the early stages of obesity. Although the molecular mechanism for insulin resistance in obesity is still unknown, hyperinsulinemia induces insulin receptor loss by means of the down regulation mechanism, and prolonged hyperglycemia may induce the impairment of insulin receptor kinase in the skeletal muscles in obese subjects. These dysfunctions in insulin signaling may cause the deterioration of insulin sensitivity, resulting in worsening glycemic control. Thus dysfunction of insulin receptor signaling in skeletal muscles may be a target for preventing diabetes in obese subjects.

To examine the clinical outcome for patients with myocardial infarction and to analyze clinical predictors for long-term prognosis, 1,000 patients were studied retrospectively. Between January 1983 and December 1987, 1,002 consecutive patients with myocardial infarction, who resided in the Kyoto and Shiga districts, were reviewed after coronary arteriography, but in two patients medical records were not located. During 3.3 +/- 2.0 years, 75 patients died of cardiac causes and 301 experienced cardiac events (death, reinfarction, and revascularization). Overall 5-year cardiac mortality was 8% and cardiac event rate was 35%. Among determinants of age, smoking, hypertension, diabetes mellitus, heart failure, postinfarction angina, serious arrhythmia, mitral regurgitation, digitalis and diuretics administration, ejection fraction (EF), left main trunk disease, and number of diseased coronary arteries selected by univariate analysis, multivariate analysis revealed that heart failure, EF, number of coronary vessel disease, diabetes, and mitral regurgitation were the important predictors of cardiac death. For cardiac events, multivariate analysis demonstrated that the number of diseased coronaries, postinfarction angina, and left main trunk disease were significant predictors. Therefore, impaired left ventricular function and myocardial ischemia appear to be important markers for cardiac death, but impaired left ventricular function does not appear to be a predictor for cardiac events. The data obtained in this study will be useful in the assessment of patients with myocardial infarction and will be of clinical significance in predicting mortality and cardiac events.

For the purpose of obtaining basic data and for establishing a support system for elderly people with various health and social problems, a population survey was performed in 1990 to investigate the health and living conditions of elderly people living alone, elderly couples and the bedridden elderly in the town of Shigaraki, Shiga Prefecture. A total of 275 subjects (103 male, 172 female) 65 years of age and over were surveyed. The participation rate in this survey was 88.1%. Analysis of health conditions (morbidity rate, blood pressure, electrocardiograph and blood examination data) of elderly people living alone, elderly couples and the bedridden elderly produced the following: 1) Stroke was the main cause of being bedridden in men, while in women, bone and joint disease, especially fracture, was the main cause. 2) The combined prevalence of hypertension and borderline hypertension in elderly people living alone, elderly couples and the bedridden elderly was over 50%. The bedridden elderly had a lower prevalence than elderly people living alone and elderly couples. 3) Men in all of the above mentioned life styles, had a higher tendency of showing ECG abnormalities than women. The tendency for major ECG abnormalities was high for bedridden elderly, both male and female, with the tendency for men being higher. 4) In bedridden elderly, a tendency of higher prevalence of anemia, in both male and females, lower total serum cholesterol and triglyceride in males compared to elderly people living alone and in elderly couples, was observed.

Recent studies have described a linkage between angiotensin converting enzyme (ACE) gene polymorphism and hypertension in a large number of hypertensive sibs. Moreover, among Japanese, the DD genotype of the ACE gene has been reported to be a genetically predisposing factor for hypertension in a large general population. However, there is some controversy regarding the association between the ACE insertion/deletion (I/D) polymorphism and systemic hypertension. Therefore, we examined the influence of the ACE I/D polymorphism in a random Japanese population. The participants were 2,892 subjects (1,110 males: mean age, 58.4 +/- 15.5; 1,782 females: mean age, 56.2 +/- 15.7) who underwent medical examinations in 1999 in Shigaraki, a suburban town located in an urban area in Shiga prefecture. Among them, 2,395 subjects (917 males: mean age, 58.0 +/- 15.7; 1478 females: mean age, 56.3 +/- 15.6) who gave their informed consent for genetic analysis were enrolled in the present study. Every year since 1991, we have repeatedly performed medical examinations in Shigaraki. ACE genotypes were determined by polymerase chain reaction (PCR) methods. Logistic analysis revealed that age (p < 0.001; odds ratio = 1.091), body mass index (BMI) (p < 0.001; odds ratio = 1.211), and family history of hypertension (p < 0.001; odds ratio = 0.371) were associated with hypertension (systolic blood pressure greater than 140 mmHg and diastolic greater than 90 mmHg). There was no association between ACE polymorphism and blood pressure. There were also no significant differences in blood pressure among males or females across the three genotypes. Moreover, in an analysis of 1,484 subjects (549 males: mean age, 62.8 +/- 12.1; 935 females: mean age, 61.2 +/- 12.6) who were followed-up since 1991, there was no association between ACE polymorphism and changes in blood pressure (p = 0.3905). We conclude that ACE polymorphism does not appear to have any significant association with blood pressure, changes in blood pressure or sex in Japanese subjects, who have a more homogeneous genetic background than any other group reported to date.

We conducted prospective surveillance of childhood hemolytic uremic syndrome (HUS) from 1997 to 2001 to describe disease incidence and clinical, epidemiologic and microbiologic characteristics. We compared our findings, where possible, with those of a previous study conducted from 1985 to 1988. The average annual incidence of HUS for the United Kingdom and Ireland (0.71/100,000) was unchanged from 1985 to 1988. The overall early mortality had halved, but the reduction in mortality was almost entirely accounted for by improved outcome in patients with diarrhea-associated HUS. The principal infective cause of diarrhea-associated HUS was Shiga toxin-producing Escherichia coli O157 (STEC O157), although in the 1997-2001 survey STEC O157 phage type (PT) 21/28 had replaced STEC O157 PT2 as the predominant PT. The risk of developing diarrhea-associated HUS was significantly higher in children infected with STEC O157 PT 2 and PT 21/28 compared with other PTs. Hypertension as a complication of HUS was greatly reduced in patients with diarrhea-associated HUS.

In the classic form of hemolytic uremic syndrome associated with toxins of gram-negative enterobacteria, mortality in the acute stage has been lower than 5% since 1978 (data from the Nephrology Committee, Argentine Society of Pediatrics). Children usually die because of severe involvement of the central nervous system, intestine, or myocardium and its complications, or because of intercurrent infection. Treatment in this phase is supportive, and efforts should be put into prevention of infection by Shiga-like toxin-producing enterohemorrhagic Escherichia coli. Of the 95% who survive, approximately one third is at risk for having chronic sequelae. Motor, sensory, or intellectual deficits, intestinal strictures, myocardial infarctions, or diabetes are infrequent. The more-frequent chronic renal lesion is characterized by the hyperfunction of nephrons remaining after the acute necrotizing lesion, which leads to progressive scarring, and not by persistence or recurrence of the microangiopathic process. Three courses of progression to end-stage renal failure have been described. Children with most severe forms do not recover from acute renal failure and enter directly into a dialysis and transplantation program. A second group recovers renal function partially, with persistent proteinuria and frequently hypertension; progression to end-stage renal failure occurs in 2 to 5 years. The third group may recover normal serum creatinine and creatinine clearance, with persistent proteinuria. They are at risk of progressing to chronic renal failure and end-stage renal disease after more than 5 years, and sometimes as late as 20 years, after the acute disease. Treatment should aim at preventing the mechanisms associated with progressive renal scarring. Transplantation is indicated in this form of hemolytic uremic syndrome, because there is little, if any, risk of recurrence, and the prognosis is similar to that of transplantation for other diseases.

We examined the interactions between lifestyle and polymorphisms of salt-sensitive genes and their effects on hypertension in a general Japanese sample (The Shigaraki Study). The study group consisted of 2,902 subjects who underwent a medical examination in 1999 in Shigaraki, a suburban area in Shiga. Among 1,647 subjects not receiving antihypertensive medication, in a combined analysis of angiotensinogen (AGT) and adducin (ADD1) polymorphisms, double homozygosity of 235Thr or 460Trp was not found to be associated with hypertension. A multiple logistic regression analysis showed that age (odds ratio [OR]: 1.07, 95% confidence interval [95% CI]: 1.06-1.08), body mass index (BMI) (OR: 1.18, 95% CI: 1.13-1.23), alcohol consumption (OR: 1.39, 95% CI: 1.16-1.66), family history of hypertension (OR: 1.57, 95% CI: 1.18-2.07), and combined AGT M235T Thr/Thr and ADD1 Trp/Trp polymorphisms (OR: 1.37, 95% CI: 1.03-1.82) were associated with hypertension. However, there was no interaction between eating salty food and combined AGT and ADD1 polymorphisms. Furthermore, eating salty food was not associated with hypertension in a multivariate analysis. Therefore, a combination of the AGT and ADD1 polymorphisms appears to be associated with hypertension. However, a simple questionnaire regarding salt intake was not sufficient to confirm the relationship between salt intake and hypertension and/or salt-sensitive genes.
