The authors studied the data concerning 101 patients who had undergone erroneous laparotomy for suspected acute surgical disease; these accounted for 0.4% of all the patients who were operated on for emergency indications in the same period. Eleven patients died. The operation was undertaken for an erroneous diagnosis of acute appendicitis (32 patients), acute cholecystitis (18), perforating gastric ulcer (15), peritonitis of unknown etiology (14), acute intestinal obstruction (5), strangulated hernia (3), destructive pancreatitis (3), tumor of the large intestine complicated by obstruction (3), abdominal abscess (2), thrombosis of the mesenteric vessels (1), ovarian apoplexy (1), closed abdominal trauma with injury to the viscera (4 patients). Diseases simulating the clinical picture of "acute abdomen" but not requiring an emergency operation were as follows: female reproductive (20 patients), pancreatic (11), renal diseases (11), hepatitis, cirrhosis of the liver (10), cardiovascular (9), pulmonary diseases (5), mesoadenitis (5), Crohn's disease (3), chronic colitis (3), carcinomatosis of the peritoneum (3), herpes zoster (3), and other diseases and injuries (20 patients). The main causes of the diagnostic and tactical errors were objective difficulties in the differential diagnosis due to similar symptomatology, as well as errors in the examination of the patient and haste in making a decision to make an operation.

Researchers analyzed 1983 vital statistics for Taiwan using the life table analysis and calculating the potential years of life lost (PYLL) to identify life shortening features of several major causes of death and examine the preventability of premature mortality. Life expectancy for males was 69.9 years whereas for females it was 75.1 years. these corresponding life expectancies for Japan were 73.8 years and 79.6 years and 71.7 years and 78.7 years for the US. Between 1950-1983, life expectancy at birth in Taiwan increased 17.5 years for males and 19 years for females. In 1983, the cumulative total of PYLL before age 70 for males was 737,205 compared to 353,780 years for females. Thus loss of productivity of males was 2 times that of females. Most of this loss was a result of accidents. In fact, they contributed to 37.2% of PYLL for males and 24.9% of PYLL for females. Even though accidents were also the leading cause for the most PYLL in Japan and the US (17.4% and 8.7% respectively in Japan and 25% for both sexes combined in the US), the magnitude was considerably lower than that of Taiwan. Further the type of accidents males were more likely to die from were motor vehicle accidents (18,8% vs. 18.4% for home and workplace accidents). On the other hand, women were more likely to die from home and workplace accidents(14% vs. 10%). The 2nd major cause for the most PYLL was all cancers, except liver cancer, (15.9% for males and 20.4% for females). The 3rd major cause for the most PYLL for males was liver disease (liver cancer and cirrhosis of the liver) (9.6%) while for females it was stroke (8.7%). Further suicides contributed to 6.5% of PYLL for females. IN conclusion, Taiwan should place accident prevention as a high priority since it needs limited resources and is more achievable than that of cancer elimination. The next level of preventive efforts should include stroke and suicide.

An office and autopsy study was performed to see if early graying was associated with increased morbidity, earlier age at death, and specific cause of death. 195 consecutive office patients over the age of 40 were studied to see if premature graying of scalp hair (50% or more gray before age 50) was associated with increased incidence of disease before age 50 (P = ns). Their parents' mean ages at death, prematurely gray or not, were compared. For fathers, mean age at death if prematurely gray was 68.27 years; if not prematurely gray, 66.03 years (P = 0.35). For mothers, the values were 70.55 years and 70.37 years respectively (P = greater than 0.50). 874 autopsy patients dying over a 23-year period (1966-1989) were studied to see if the median age at death (of patients 50% or more gray) differed for any of the six categories of disease (myocardial infarction, congestive heart failure, cancer, stroke, pneumonia/bronchitis, or cirrhosis of the liver/GI problems) when compared to the entire autopsy sample of 19 categories of disease (P = ns for each comparison). This dual office and autopsy study provides no evidence to support the contention that early gray hair is a risk factor.

In 17 compensated liver cirrhosis and 8 chronic hepatitis cases (no histories of cardiac or pulmonary disease), wedged hepatic venous pressure (WHVP), hemodynamics, and pulmonary function were measured and their clinical significance and interrelations evaluated. Both diseases were comparatively analyzed. WHVP was determined by wedging a catheter from the right femoral vein into the right hepatic vein. Hemodynamics was measured with a Swan-Ganz catheter. Spirography, flow-volume curve, closing-volume curve and pulmonary diffusion capacity were measured and aortic blood gas analyzed to assess pulmonary function. Esophageal endoscopy was used to diagnose the presence or absence of esophageal varices. The results showed that the group of liver cirrhosis patients featured elevated WHVP and a hyperhemodynamic pattern and a positive correlation between WHVP on the one hand and cardiac index and right left ventricle stroke work indexes on the other; there was a negative correlation between WHVP and the systemic vascular resistance and pulmonary vascular resistance indexes. The results showed an increase in oxygen consumption in the group of patients with esophageal varices. In all chronic hepatitis cases, findings were normal. Pulmonary function was characterized by abnormal %VC, PaO2, and pulmonary diffusion capacity in both groups along with abnormal PaCO2 in the liver cirrhosis group; no significant differences were noted between the two groups. These results indicate that liver cirrhosis elevates intarahepatic pressure, affecting systemic hemodynamics and resulting in a circulatory distribution disorder, leading to right and left ventricle overload and a decline in potential cardiac function. The results also indicated that mild pulmonary function disorder can occur as early in a state of chronic hepatitis.

The effect of changes in body posture on estimated hepatic blood flow (EHBF) and various hemodynamic parameters was examined in 15 patients with compensated cirrhosis. EHBF and various hemodynamic parameters were first measured with the patients in the supine position, and then again 10 min after tilting to 45 degrees. EHBF was 1089 +/- 315 ml/min at supine and 1065 +/- 328 after tilting; the difference was not significant. However, the patients were then divided into two groups according to the magnitude of the decrease in EHBF after tilting, with those showing a decrease of 10% of more assigned to group B, and those showing a decrease of less than 10% assigned to group A. It was found that ICG (R15) and BSP (R45) were significantly higher in group A. Meanwhile, among hepatic and systemic hemodynamics, wedged hepatic venous pressure, hepatic venous pressure gradient, free hepatic venous pressure, cardiac index, systolic blood pressure, systemic vascular resistance, and stroke volume were found to have changed significantly after tilting. These results suggest that posture change has no effect on EHBF in compensated cirrhotic patients.

The usefulness of surveillance in relating chronic disease trends to recent changes in risk exposures is often questioned on the grounds that these trends respond slowly, reflecting long periods between aetiological exposures and clinical onset of disease. We challenge this preconception on the basis of a review of several important risk factors and diseases: alcohol and liver cirrhosis; tobacco and stroke, cardiovascular disease, and lung cancer; and oestrogens and endometrial cancer. Data from cohort, cross-sectional, and modelling studies demonstrate that the time between removal of exposures and the onset of decline in morbidity or mortality is not defined by the time between initial exposure and disease occurrence. Rather, the pattern of lifetime exposures (with recent exposures often having a dominant effect), the dynamics of the disease process, and the segment of the population with reduced exposures determine how soon the decline begins.

The peptide, 7B2, originally isolated from pituitary, has been shown to be present in endocrine tumors of high concentrations in pancreatic islet tumors. Plasma from most of these patients showed very high 7B2 immunoreactivity (IR-7B2) though there is a lack of knowledge concerning physiological and pathological changes in plasma IR-7B2 levels in other conditions. To assess whether or not there is any alteration in circulating IR-7B2 levels due to age, sex or any specific condition, plasma levels of IR-7B2 were measured in the fasting state in 106 healthy subjects aged 3 months to 91 years, 101 diabetics, 28 patients with hyperthyroidism. 7 patients with primary hypothyroidism, 13 patients with liver cirrhosis, 43 patients with chronic renal failure, 35 patients with cerebral vascular accident, and 26 pregnant subjects. Twenty-four cord bloods were also included. The responses of circulating IR-7B2 to oral glucose, intravenous arginine infusion, volus thyrotropin (TRH) or volus luteinizing hormone-releasing hormone (LH-RH) injection were also evaluated. Particularly high IR-7B2 levels were found to exist in cord blood. Postnatally the concentrations decreased gradually with age to adult values (15.6 +/- 2.9pmol/liter (mean +/- SE) in 20's-60's), though plasma IR-7B2 levels again increased significantly in over 70's (37.1 +/- 3.2pmol/liter; P less than 0.01). There was no significant difference in plasma 7B2 levels in either sex. Among the pathological conditions studied, significantly high IR-7B2 levels were observed in patients with chronic renal failure (175.1 +/- 35.9pmol/liter). Some of the pregnant patients in their third trimester also showed high plasma IR-7B2 levels. A small but significant rise in plasma IR-7B2 was observed after a glucose load in control subjects and diabetics. Intravenous LH-RH exerted a rise in plasma 7B2 concentrations though arginine and TRH showed no significant effect on plasma IR-7B2 concentrations. Compared with the plasma concentrations, ten to fifty-fold high levels of IR-7B2 were observed in cerebrospinal fluid (CSF) from patients with cerebrovascular accidents or multiple sclerosis. These results suggested that the kidney plays a major role in 7B2 degradation and that LH-RH simulates IR-7B2 release from the pituitary gland. Whether reduced clearance or increased production was responsible for the IR-7B2 elevation in subjects under 10 years or over 70 years requires investigation. Furthermore, high levels of IR-7B2 in CSF might indicate its specific role for the central nervous system.

Hypertension can be ameliorated by certain concomitant disease states, especially those in which serum globulin is elevated. Blood pressure has been reduced in cases of cirrhosis of the liver, chronic alcoholism, congestive heart failure, arthritis, hypothyroidism, and myeloma. These clinical findings were confirmed experimentally when animals with various models of hypertension became normotensive after the development of a modest degree of liver damage with hyperglobulinemia. Other diseases, not associated with hyperglobulinemia, that can lower blood pressure are stroke, uremia, hyperparathyroidism, and malnutrition. When any of these diseases occur in hypertensive patients, their influence on blood pressure must be considered when determining treatment and prognosis.

Plasma noradrenaline and adrenaline concentrations were measured in 75 patients with cirrhosis in order to attempt to correlate these concentrations and liver failure and hemodynamic changes. The increased noradrenaline concentration was not correlated with the degree of liver failure estimated by Pugh's classification, with the cause of cirrhosis, with the presence of acute alcoholic hepatitis or with the presence of ascites. Adrenaline concentration was higher in cirrhotic patients with acute alcoholic hepatitis than in those without these lesions. Noradrenaline concentration was significantly correlated with heart rate, wedged hepatic venous pressure and renal blood flow. Noradrenaline concentration was also negatively correlated with stroke volume and adrenaline concentration was negatively correlated with cardiac output and stroke volume. These findings confirm the relationships between portal hypertension, sympathetic hyperactivity and renal function in patients with cirrhosis.

Clinical studies using 31P and 1H MRS with a whole body 2.0 T MRI/MRS system are described. In most cases, techniques to quantitate absolute molar concentrations of metabolites in various organs were used. In the brain, AIDS, chronic stroke, and white matter lesions were associated with alterations of brain 31P metabolites. Epilepsy was associated with increased pH in the seizure focus. In the heart, dilated cardiomyopathy was associated with increased PDE/ATP while PCr/ATP was unchanged. In the liver, alcoholic hepatitis and cirrhosis were associated with diminished hepatic ATP while alcoholic hepatitis had increased pH and cirrhosis had decreased pH. This allowed differentiation of normal liver, alcoholic hepatitis, and alcoholic cirrhosis without biopsy. In the prostate, malignancy was associated with increased PME/ATP and decreased PCr/ATP. The PME/PCr was greatly increased in malignant prostate with no overlap in normals. Other cancers outside the brain had increased PME and effective treatment was often associated with diminished PME. 1H MRS of the brain was performed using ISIS and outer volume suppression pulses for volume localization. Excellent high resolution 1H water-suppressed spectra were obtained at echo times as short as 30 ms, showing well resolved peaks for lactate, N-acetylaspartate, glutamate, choline, creatinine, and inositol. 1H MRS demonstrated that the uptake of ethanol by the brain was slower than the rise of ethanol in blood. 31P spectroscopic imaging of the brain with resolution of 2.25 x 2.25 x 2.5 cm produced metabolic images and high resolution spectra from desired regions of interest.(ABSTRACT TRUNCATED AT 250 WORDS)
