Between 1985 and 1988, a two-phase epidemiological study was conducted at the "Ruta 100" company in Mexico City to examine the harmful effects of the working conditions on drivers of urban transport vehicles. In the first phase, five groups of nine drivers each were interviewed regarding their opinions about their working conditions and possible work-related disorders. On the basis of this information, an epidemiological survey was developed and applied using a polytypic sampling design to some 200 drivers plus two other groups of approximately the same size, one consisting of maintenance workers and the other of office workers, which served as controls. The driver group showed a high prevalence of respiratory and neuropsychiatric disorders, diarrhea, myopia, arterial hypertension, urinary disorders, hemorrhoids, hearing loss, back pain, varicose veins, peptic ulcers, diabetes, cardiopathies, abdominal hernias, and appendicitis. For arterial hypertension, hemorrhoids, nervous disorders, and psychiatric disorders the prevalence ratios of drivers/maintenance workers and drivers/administrative workers were statistically significant.

An histochemical research on cholinergic and noradrenergic fibres of the adventitia layer and of the myenteric plexus of the terminal ileum from rats with streptozotocin-induced diabetes, after 20 weeks of evolution of the illness, was carried out to study changes in the innervation of the gut. The cholinergic nerves, revealed through their acetylcholinesterase activity, did not present alterations, but an evident reduction in number of the noradrenergic nerves and swollen intensely fluorescent varicosities, were observed, both in the perivascular and myenteric plexus of terminal ileum from diabetic animals.

The clinical use of estrogens and progestogens for menopausal women is reviewed, discussing the indications, results of studies on effectiveness of various agents o each target organ, contraindications, risk-benefit ratio, and types of drug preparations available and used in European countries. The indications for menopausal hormone replacement are primarily to prevent myocardial infarction and osteoporosis, and also to treat early menopause, urogenital atrophy, and severe skin, mucous membrane and psychic disorders. Mechanisms of action of estrogens and progestins, and anticipated results are detailed for each of the indications. Contraindications typical of oral contraceptives usually do not apply for hormone replacement. For example, only severe acute liver disease, current thromboembolism, endometrial cancer other than I, and breast cancer within 3-5 years of primary treatment are contraindications. Neither cervical, ovarian or vulvar cancer, diabetes, varicose veins, hypertension, nor history of liver disease or thromboembolism are contraindications: in some cases progestins or transdermal estrogens are recommended. Estrogen side effects suggest overdosage. Progesterone or its derivatives rather than oral contraceptive progestins are prescribed. There is a clear benefit, comparing cost of medication to that of treating consequences of estrogen deficiency. The preparations currently used in Europe include oral micronized estradiol, conjugated estrogens, transdermal patches, local vaginal estrogens, and injectable estradiol esters for those who cannot tolerate oral or transdermal agents. Preparations should contain progesterone unless the woman has had a hysterectomy. Combinations designed to avoid withdrawal bleeding are available.

The prevalence of reported chronic diseases was studied in quintiles of waist/hip ratio and Quetelet index in 11,825 women aged 40-73 presenting for mammographic screening in the DOM-project. After adjustment for age and Quetelet index, increased waist/hip ratio was found to be associated with an increased prevalence of diabetes mellitus, hypertension, cholecystectomy and a lower prevalence of varicose veins. No associations were observed between waist/hip ratio and the prevalence of angina pectoris, gout and rheumatism. The odds ratios, adjusted for age and Quetelet index, of the highest versus the lowest quintile of waist/hip ratio were 3.4 (95% CI 1.4-8.3) for diabetes mellitus; 2.2 (95% CI 1.7-2.8) for hypertension; 2.0 (95% CI 1.2-3.4) for cholecystectomy, and 0.81 (95% CI 0.68-0.95) for varicose veins. After adjustment for waist/hip ratio and age, Quetelet index was found to be associated with an increased prevalence of hypertension, cholecystectomy and varicose veins. Quetelet index, however, was not found to be related to diabetes, gout or rheumatism. We conclude that in a representative sample of Dutch women older than 40 years, fat distribution in addition to overweight is related to important chronic diseases.

This article reviews the history of screening in the elderly, the conditions that should be considered, whether or not screening in the elderly is of benefit, whether we should look for disability or diseases and where screening should take place. Thirteen conditions are discussed: hearing loss and anaemia in some detail. Both disability and precise diagnostic criteria are considered. The place where screening is best carried out depends on the mobility of the subject and the nature of the particular screening tests selected for the 13 conditions. The desirability of screening was assessed on the following criteria: prevalence of the condition, severity of the problem, acceptability by the patient of the screening test, false positive rate, consequences of making a false positive diagnosis, the false negative rate and the consequences of this error, the effect of treatment, the cost of the screening test and the burden on the health services produced by the screening test. The criteria were scored 1-5 on a scale defined for each assessment, with higher scores favouring screening. We provide evidence that screening may be worthwhile for: need for chiropody, varicose veins/ulcer, hearing loss, obesity, visual impairment, hypothyroidism, hypertension, anaemia and diabetes mellitus. However, the assessments discussed in this paper need to be tested prospectively in randomised controlled trials.

Despite prophylaxis with low-dose heparin (LDH), postoperative thromboembolism (TE) still occurs in 10 per cent of patients undergoing abdominal operations. To identify predictors of TE in spite of LDH, 171 patients undergoing abdominal operations and receiving LDH were screened with the fibrinogen uptake test. Diagnosis of TE was confirmed in 24 (14 per cent; 95 per cent confidence limits of 9 to 20 per cent) by either venography or pulmonary scintigraphy, or both, or autopsy. As analyzed by multiple logistic regression, only age, body mass index, preoperative hemoglobin concentration and colorectal operations (yes or no) contributed to the prediction of failure of LDH, whereas sex, malignant lesion, previous TE, hypertension, diabetes mellitus and varicose veins did not. Based on the first 81 patients, an index was constructed that was able to identify 11 of 13 patients with TE and exclude 34 of 68 without TE. This index was then applied on a second series of 90 patients in whom it correctly identified ten of 11 patients with TE and excluded 40 of 79 patients without TE. It is concluded that, with the use of the index, it is possible to identify a group of patients undergoing elective abdominal operations in whom LDH is not sufficient prophylaxis. A practical approach to bedside prediction of failure of LDH prophylaxis by use of a simple score table is suggested.

The distribution of vasoactive intestinal polypeptide (VIP) and substance P-like immunoreactivities was studied by immunohistochemistry in the myenteric plexus and circular muscle layer of the ileum and proximal colon of rats 8 wk after induction of diabetes with streptozotocin. A consistent increase was observed in fluorescence intensity of VIP-like immunoreactivity in the nerve fibers, and intensely stained cell bodies were significantly more frequent in the myenteric plexus of the ileum (p less than 0.001) from diabetic animals. Some varicosities of VIP-like immunoreactive fibers in the myenteric plexus appeared to be enlarged. Vasoactive intestinal polypeptide-like immunoreactivity was increased and VIP-like immunoreactive nerves appeared thicker in the circular muscle layer of both diabetic ileum and proximal colon. The VIP levels were measured biochemically in tissue consisting of the smooth muscle layers and myenteric plexus. A significant increase in the VIP content per centimeter of intestine was found in both the ileum (p less than and proximal colon (p less than 0.01) from diabetic rats. In contrast, no apparent change in substance P innervation was observed immunohistochemically in the myenteric plexus and circular muscle layer of either diabetic ileum or proximal colon when compared with controls. The results are discussed in relation to the symptoms of autonomic neuropathy of the gut in diabetes.

During the recent 5 2/3 years, hepatic resection was performed on 118 patients with hepatocellular carcinoma. Ages ranged from 17 to 78 years with an average of 57 years. There were 101 males and 17 females. Underlying cirrhosis of the liver was found in 101 cases, and chronic hepatitis was found in 16 cases. Before surgery 62 patients had 71 associated conditions such as esophageal varices, diabetes mellitus, cholelithiasis, or peptic ulcer. Operations for the varices and cholelithiasis were performed simultaneously with hepatic resection in 15 and six patients, respectively. The operative mortality rate within 1 month was 7.6%, and the overall in-hospital death rate was 14.4%. In 94 patients with curative resection, the 2-year survival rate was 81.2% in patients without cirrhosis and 55.4% in patients with cirrhosis. The 4-year survival rate was 81.2% in the former and 34.8% in the latter group. The prognosis was significantly better in patients without cirrhosis than in those with cirrhosis. On the contrary, 21 of 24 patients with palliative resection died within 2 years despite extensive chemotherapy. The present results may indicate that the resectability rate of hepatocellular carcinoma is currently increasing, even in the presence of cirrhosis of the liver due to early detection of the tumor by current advances in diagnostic methods and also that major hepatic resection is possible in selected patients with cirrhosis.

The distribution of adrenergic and vasoactive intestinal polypeptide-, neuropeptide Y- and substance P-immunoreactive nerves was studied histochemically and immunohistochemically in the irides of rats 8 weeks after the induction of diabetes with streptozotocin. In the control animals, catecholamine-containing, vasoactive intestinal polypeptide- and substance P-immunoreactive nerve fibres were found in the constrictor pupillae, dilator muscle and the ciliary processes. They also formed perivascular nerve plexuses of blood vessels in the dilator muscle. Neuropeptide Y-immunoreactive nerve fibres were only observed in the dilator muscle and ciliary processes. In the irides from diabetic animals, a considerable increase was observed in the fluorescence intensity and/or density of vasoactive intestinal polypeptide-immunoreactive nerves. Some varicosities of the vasoactive intestinal polypeptide-immunoreactive nerves appeared enlarged. In contrast, no apparent change in the density and/or fluorescence intensity of catecholamine-containing, neuropeptide Y- and substance P-immunoreactive nerve fibres was observed in the irides from diabetic animals when compared with controls. The results are discussed in relation to the symptoms of autonomic neuropathy of the irides in diabetes.

The 5-years-survival rate of patients with liver cirrhosis is limited to about 25%. Still, one of the most important therapeutic procedures in case of bleeding oesophageal and fundic varices is a portasystemic shunt 6 randomized studies have been performed to compare the complete portacaval shunt with the incomplete splenorenal Warren-shunt: The hospital mortality rate (8-10%) and the 5-years-survival rate (43-47%) do not differ; but the rate of postoperative encephalopathy significantly is higher after PCA (40-26%) and the rate of recurrent bleeding significantly is higher after Warren-shunt (13-6%). In case of massively or early recurrent bleeding, we favour an emergency PCA: the mortality rate amounts to 12% in case of the socalled "early operation" (after initially successful balloon tube or sclerotherapy, 52 patients) and 47% in case of "absolute emergency shunt" because of continuing bleeding (119 patients). In the elective situation (58 patients) we favour the Warren-shunt in elderly patients with diabetes mellitus, preexisting encephalopathy or Child-B-classification.
