We evaluated the extent of atherosclerosis of the right gastroepiploic arteries (RGEAs) used as a graft material in coronary bypass grafting for ischemic heart diseases, with analyzing the presence of arteriosclerotic lesions and the site of predilection and studying their relationship to clinical risk factors of ischemic heart disease. The subjects were 32 cases, 18 males and 14 females, ranging in age from 32 to 80 years (mean 61 years), in which gastrectomy was performed for early gastric cancer. RGEA 20 cm in length was taken from the junction of the gastroduodenal artery of the stomach and divided into A, B, C and D at intervals of 5 cm proximally, and each part was subdivided into the length of about 5 mm to make ultra-thin sections for HE and Elastica van Gieson staining. The area of intima (I), the area of media (M) and circumference of media (L) were calculated. The arterial section was transformed to a hypothetical state in which the internal elastic lamina was stretched to make an exact circle. The degree of stenosis "I" was expressed by the following formula. [formula: see test] The maximum value of "I" in the sections A, B, C and D in individual cases was designated as Ar, Br, Cr and Dr, and the maximum value of "I" among the four sections in each case was defined as R. Atherosclerosis was graded according to R value as follows. I; R < 25%, II; 25% < or = R < 50%, III; 50% < or = R < 75%, IV; 75% < or = R.(ABSTRACT TRUNCATED AT 250 WORDS)

In Japan, elderly patients who develop myasthenia gravis (MG) are increasing in number. However, there are few clinical reports concerning this issue. We evaluated the clinical manifestations, inducing or exacerbating factors, complications, treatments and prognosis of systemic MG in 11 patients older than 60 years of age. Bulbar symptoms were more frequent in these patients compared with younger MG patients, and 6 out of 11 cases (54.5%) were mistakenly diagnosed as cerebrovascular disorders. Among inducing or exacerbating factors of MG were psychological problems inherently involved with the aged, physical factors, and inappropriate termination or rejection of medication. Increase in the level of anti-Ach-R antibodies was recognized in 10 out of 11 cases (90.9%). A high percentage of the patients had thymoma (36.4%) and thyroid diseases (45.5%): 3 with Hashimoto's thyroiditis (27.3%), 1 with thyroid ophthalmopathy associated with hyperthyroidism, and 1 with simple goiter. Others were accompanied by ischemic heart disease, prostatic hypertrophy or stomach cancer. We treated these patients with corticosteroids, immunoglobulin, radiation for thymoma, or thymectomy in addition to administration of anticholinesterase agents. Prognostically, we found that duration of illness before death was shorter in those with onset later than 70 years of age. Seven out of 11 (63.6%) patients died of either aspiration pneumonia (4 cases), complications of thymectomy, congestive pulmonary edema or stomach cancer. There were no deaths associated with myasthenic crisis.

Between April 1984 and December 1992, 8 patients with concomitant malignant tumor were treated surgically for cardiac disease. The mean age was 58 years (range: 51 to 69), and there were 6 males and 2 females. There were 2 cases of ischemic heart disease, 3 cases of valvular heart disease, and 1 case of atrial septal defect (ASD). Gastric cancer was present in 4 cases, malignant tumor of hepatobiliary tract in 2, rectal cancer in 1, and lung cancer in 1. All patients were operated on in a two-stage fashion. In 6 cases, cardiac surgery including coronary artery bypass grafting (4 patients) and valve replacement (2 patients) were performed with an average of 58 days prior to the tumor resection. The other 2 patients underwent radical operation for a gastric or rectal cancer, followed by cardiac surgery for ASD or mitral stenosis about 2 months later. One patient died of respiratory failure 56 days after lobectomy following coronary artery bypass. There was one late death of local recurrence of rectal cancer 2 years after the operation. In conclusion, good surgical result can be expected with sequential operations for cardiac disease and malignant tumor, if curative resection of the tumor is possible.

The cohort consisted of 11,178 Mead Corporation employees (9,358 males and 1,820 females) who had worked for at least one year between January 1, 1975 and December 31, 1992 at seven pulp and/or paper mills in the United States. The vital status of the cohort was determined through a variety of sources over an observation period of 17 years (1976-1992). Mortality data were analyzed in terms of cause-specific standardized mortality ratios (SMRs), with expected deaths based on U.S. national mortality rates. Job categories with similar exposures were created based on an historical exposure assessment. Mortality analyses were performed separately for total female and male employees. Among female employees, overall mortality was less than expected, and no significant cause-specific mortality excesses were observed. The small number of deaths among female employees did not permit further detailed analyses. Among male employees, statistically significant deficits from overall mortality (SMR = 69.0) and from all cancers (SMR = 71.3) were reported. In addition, low mortality risks for many specific causes were also observed, including many specific cancer sites, various types of cardiovascular diseases, and different forms of nonmalignant respiratory diseases. In particular, there was no mortality excess from lung cancer (SMR = 77.5), digestive cancer (SMR = 69.4), stomach cancer (SMR = 46.7), laryngeal cancer (no observed death), rectal cancer (SMR = 82.8). Hodgkin's lymphoma (no observed death), non-Hodgkin's lymphoma (SMR = 103.6), leukemia (SMR = 72.2), diabetes mellitus (SMR = 110.4), ischemic heart disease (SMR = 80.0), and nonmalignant respiratory diseases (SMR = 36.7). Furthermore, detailed analyses by length of employment, interval since hire (latency), and job category demonstrated no occupationally related mortality increases from any of the diseases examined. Specifically, based on internal comparisons, no upward trends in cause-specific mortality risk were observed by duration of employment. In conclusion, the results of this epidemiologic investigation demonstrated a favorable mortality experience for employees at the seven pulp and/or paper mills.

As part of the Global Burden of Disease Study, three scenarios of future mortality and disability were identified. The scenarios were based on future health status as a function of projected changes in key socioeconomic variables that influence health status. Regression equations for mortality rates for nine cause-of-death clusters were developed by region based on gross domestic product per person, average number of years of education, time (as a proxy for technological change), and smoking intensity. Life expectancy at birth was projected, in all three scenarios, to increase for women (to about 90 years in established market economies by 2020), with far smaller gains in male life expectancy. Worldwide, annual mortality from communicable maternal, perinatal, and nutritional disorders (group 1 causes) is expected to decline from 17.2 million to 10.3 million in 2020 in the baseline model. Also expected is a very large increase in deaths from non-communicable diseases (group 2 causes) from 28.1 million in 1990 to 49.7 million in 2020. Deaths from injuries (group 3) are projected to increase from 5.1 million to 8.4 million. Diarrheal diseases, perinatal disorders, measles, and malaria are expected to decline dramatically as causes of death in the 1990-2020 period, while lung cancer, stomach cancer, war injuries, liver cancer, and HIV are expected to move up five or more places in the ranking. In 2020, the 10 leading causes of disability-adjusted life-years (in descending order) are projected to be ischemic heart disease, unipolar major depression, road traffic accidents, cerebrovascular disease, chronic obstructive pulmonary disease, lower respiratory infections, tuberculosis, war injuries, diarrheal diseases, and HIV. Tobacco-attributable mortality is projected to increase from 3.0 million in 1990 to 8.4 million in 2020 (9% of the worldwide mortality burden).

Helicobacter pylori is associated with different diseases: duodenal ulcer, rosacea, ischaemic heart disease and gastric cancer. Given the abnormal immunological response and the high prevalence of gastrointestinal symptoms in diabetic patients, we conducted a study on H. pylori prevalence among these patients. We designed a case control study of a population-based cohort. Eighty insulin-dependent diabetes mellitus (IDDM) patients with an average age (24.05 +/- 8.3 years), and 100 control subjects (25 +/- 7.1 years) were selected to verify the seroprevalence of Helicobacter pylori in these populations. One serum sample was obtained from each subject for evaluation of antibodies against Helicobacter pylori, parietal cells (APA) and pancreatic islets cells (ICA). The seroprevalence of H. pylori among IDDM patients aged less than 24 years was significantly higher than among control subjects; the corresponding rate among IDDM aged greater than 24 years was significantly lower than among control subjects. Antibodies against parietal cells (APA) and islet cells (ICA) among H. pylori positive diabetic patients were significantly higher than among H. pylori negative diabetic patients. IDDM patients were subdivided on the basis of the evolutive course of diabetes. Seroprevalence of H. pylori as well as prevalence of ICAs decreased with IDDM duration. Nevertheless, no variation in the prevalence of APAs during the course of diabetes was observed. We observed an association between the seroprevalence of Helicobacter pylori and the duration of IDDM. The seroprevalence of H. pylori and ICA decreased with the evolutive course of diabetes mellitus among IDDM. The prevalence of ICA and APA in IDDM H. pylori positive subjects was higher than among controls.

For many decades the dictum 'no acid, no ulcer' dominated thinking on the pathogenesis of peptic ulcer. When I was a medical student, not surprisingly, the standard therapy for a peptic ulcer was an antacid possibly combined with carbenoxolone. As a medical registrar, I was involved in the early studies with H2-receptor antagonists which, at the time, many of us believed would lead to the removal of peptic ulceration as a clinically important disease. It was soon evident, however, that ulcers returned rapidly when the H2-receptor antagonist was withdrawn and the concept of maintenance therapy was born. Within about 5 years of the launch of the first H2-receptor antagonist, cimetidine, two major developments occurred namely the discovery of Helicobacter pylori and the characterisation of the proton pump with the development of drugs to inhibit its action. The discovery of H. pylori not only turned the aetiopathogenesis of peptic ulceration on its head but soon emerged as a major factor in the causation of gastric cancer and mucosa associated lymphocytic tissue (MALT) gastric lymphoma. The potential clinical impact of this organism continues to expand, with suggestions that it might be involved in growth retardation in children and possibly a factor in the development of ischaemic heart disease. The high prevalence of this organism worldwide presents clinicians and other healthcare workers with a formidable challenge with regard to its control at a population level.

In the period 1989-94, mortality rates for the most important causes of death in people migrated to the Tuscany from other Italian regions were analysed. The area of birth was assessed according to the information on province of birth recorded on death certificates. For this analysis we classified Italy into Tuscany and five broad areas, each including a number of political regions: North-West, North-East, Centre, South and Islands. The number of person-years for calculation of the mortality risks was based on 1991 census data, which also included information on place of birth and on current residence. The risks of death of subjects born in other Italian areas and resident in Tuscany ("migrated populations") in comparison to Tuscany born population were assessed by means of Poisson multivariate regression models. For most sites (particularly for lung and breast), cancer mortality rates were higher among North-West and North-East born people and lower among Centre, South and Islands born people. Gastric cancer mortality was higher in Tuscany born subjects. Cardiovascular diseases mortality was generally lower among people born outside of the Tuscany, with the exception of ischaemic heart disease (higher in North-West and Islands born people). Liver cirrhosis mortality was generally higher in North-West, North-East, South and Islands born subjects (with some differences between males and females). Diabetes mellitus mortality was higher in South and Islands born people. AIDS and opioids overdose mortality was higher in North-West born subjects. Mortality for external causes was higher in people born outside of the Tuscany. Both in males and females, overall mortality was higher in North-West and lower in South born people and lower in Centre and Islands born males.

An 81 year old man with severe ischemic heart disease and left ventricular dysfunction was scheduled for a subtotal gastrectomy for his advanced gastric cancer. His cardiac function was so poor that we performed minimally invasive coronary artery bypass grafting (MIDCAB; coronary artery bypass grafting without cardiopulmonary bypass for LAD through a small left thoracotomy), just before the abdominal operation. Anesthesia was induced and maintained with fentanyl, vecuronium and sevoflurane. To control heart rate below 60 bpm during local coronary occlusion for bypass grafting, edrophonium 5 mg was administered just before the occlusion. During the bypass grafting procedure, the patient's heart rate was maintained at 50-60 bpm and his hemodynamic profile slightly declined but was permissible. After bypass grafting, his cardiac performance was improved with low dose dobutamine. Subsequently subtotal gastrectomy was carried out. His postoperative course was uneventful. Combined MIDCAB and abdominal operation may be beneficial for selected patients with severe ischemic heart disease.

A 74-year-old Japanese woman with early gastric cancer was successfully treated with uracil and tegafur (UFT). She was diagnosed by endoscopy (including endoscopic biopsy and endosonography) with an early gastric cancer, type IIa + IIc, on the greater curvature of the angulus. Surgical procedures or endoscopic therapy could not be performed because the patient had severe ischemic heart disease. Therefore, chemotherapy with UFT was administered at 300 mg/day for 15 months. Follow-up endoscopy, endosonography, and biopsy showed disappearance of the gastric cancer. To our knowledge, this is the first case report of the complete response of an early gastric cancer to UFT in the English-language literature.
