RESUMEN
INTRODUCTION: The aim of the present population-based cohort study was to examine the association between alcohol intake and mortality from all causes, coronary heart disease, and cancer. METHODS: A prospective population study with baseline assessment of beer, wine and spirit consumption, smoking habits, educational level, physical activity, and body mass index in a total of 257,859 person-years follow-up on mortality. RESULTS: A total of 4833 participants died, 1075 of these from coronary heart disease and 1552 of cancer. Compared with non-drinkers, light drinkers, who avoided wine, had a relative risk of death from all causes of 0.90 (0.82-0.99) and those who drank wine had a relative risk of 0.66 (0.55-0.77). Heavy drinkers, who avoided wine, were at higher risk of death from all causes than were heavy drinkers, who included wine in their alcohol consumption. Wine drinkers had a significantly lower mortality from both coronary heart disease and cancer than had non-wine drinkers (p = 0.007 and p = 0.004, respectively). CONCLUSION: A moderate consumption of wine may have a beneficial effect on all causes of mortality, which is additive to that of alcohol. This effect may be attributable to a reduction in death from both coronary heart disease and cancer.

Patients with oesophageal varices without previous bleeding have a risk of 25-30% for the development of a bleeding episode within two years. It is important to identify patients with a high risk of bleeding due to the high mortality of 30-40% within six weeks after a bleeding episode. Treatment with a non-selective betablocker possibly combined with isosorbidnitrate should be initiated if an upper endoscopy shows the presence of medium- or large-sized oesophageal varices. Sclerotherapy or ligation initiated within a short time after start of an acute bleeding episode reduces mortality and risk of bleeding. Pharmacological treatment may have effect on the acute episode, and most data advocate for Terlipressin to be the first choice. If bleeding continues transjugular intrahepatic portosystemic shunt (TIPS) should be considered. Fifty to seventy percent of patients will experience a rebleeding episode if otherwise untreated. Endoscopic ligation should be preferred possibly in combination with a non-selective betablocker. If another bleed occurs the patient should be considered for TIPS or transplantation.

A questionnaire-based interview on alcohol drinking pattern in a random sample of 4,016 men and 4,179 women in 1992 was compared to an identical interview from 1979. In coherence with alcohol sale statistics, the average alcohol intake was unchanged in the population. Nevertheless, during the period drinking patterns have changed among Danes. Thus, 20 to 39 year-olds drank less, 40 to 59 years-olds drank more, fewer Danes drank during daytime, and fewer drank on weekdays at the second survey.

The procedure and results of 50 colonoscopies performed over a three-year period on a group of 43 children (range: 0.3-16 yr; median: 9 yr) are described. The main indications were evaluation for, or control of already known, chronic inflammatory bowel disease (n = 38) and rectal bleeding (n = 8). Following verbal and written information the children were admitted one to two days before the procedure for bowel preparation. Children < 10 years old received general anaesthesia during the colonoscopy (n = 25) and most children > or = 10 years old received an intravenous sedation with pethidine and midazolam (n = 25). In only one case was intravenous sedation not successful. The coecum was visualised in 96% and the terminal ileum intubated in 77% (when intended) of the endoscopies. The most important results obtained were establishment of the diagnosis of inflammatory bowel disease in 21 of 30 suspected cases and the removal of a polyp in two cases. At the time of colonoscopy a "best guess" diagnosis of either ulcerative colitis or Crohn's disease often predicted the histological diagnosis, but endoscopy tended to underestimate the severity and extent of the inflammation as compared to microscopy. There were no complications. We conclude that colonoscopy performed according to our recommendations is a safe and informative procedure for evaluation of the large bowel and terminal ileum in children with intestinal disease.

IGF-I is a single polypeptide chain with important anabolic and endocrine activities. The liver is the major source of IGF-I and its binding protein, IGFBP-3. Circulating concentrations of IGF-I and IGFBP-3 are decreased in patients with chronic liver disease and correlate with the severity. The aim of this study was to assess the additional prognostic value of IGF-I and IGFBP-3 in patients entered in a large multicentre study (EMALD). Three hundred and thirty-seven patients with alcoholic liver disease were studied in a randomised placebo-controlled trial of malotilate with a mean follow-up period of 569 days (range: 7-1544). A multivariate Cox regression analysis of pertinent clinical and biochemical variables revealed a significant independent prognostic value of years of alcohol intake, coagulation factors 2, 7, and 10, alkaline phosphatases, serum creatinine, and immunoglobulin M (IGM). When IGF-I or IGFBP-3 were added into this model, a Cox regression analysis showed that either had a significant independent prognostic value. As IGF-I and IGFBP-3 were closely correlated, they contained almost the same prognostic information. Inclusion of IGF-I gave these results: IGF-I (p < 0.03), alcohol intake (p < 0.02), coagulation factors 2, 7, and 10 (p < 0.01), creatinine (p < 0.001), and IgM (p < 0.01) contained independent prognostic information. Inclusion of IGFBP-3 gave these results: IGFBP-3 (p < 0.02), alcohol intake (p < 0.05), coagulation factor 2, 7, and 10 (p < 0.01), creatinine (p < 0.001), and IgM (p < 0.02) were independent predictors of survival. In conclusion IGF-I or IGFBP-3 provides important additional information on survival in patients with alcoholic liver disease.

The association between self-reported alcohol intake and the risk of future liver disease was studied in a population-based prospective cohort of 13,285 men and women aged 30-79 years. Diagnoses indicating alcoholic liver disease (n = 261) or cirrhosis (n = 124) were obtained from the Danish National Health Registers. The cumulated observation time was 130,558 person-years. A dose-dependent increase in risk of developing liver disease was observed with increasing alcohol intake, with the steepest increase among women. At an alcohol intake of 7-13 beverages per week for women and 14-27 beverages per week for men the relative risk was significantly greater than 1. Women had a significantly higher relative risk of developing alcohol related liver disease than men for any given level of alcohol intake. In the general population, self-reported current alcohol intake is a good predictor of the future risk of alcoholic liver disease.

In total 199 oesophago-gastro-duodenoscopies (OGD) were performed in 71 female and 71 male paediatric patients (three months-15 years, median 8 years 2 months). The endoscopy was performed in general anaesthesia in children less than five years old, and in an intravenous sedation in older patients. The indications for OGD were: recurrent abdominal pain and concomitant positive antibodies against Helicobacter pylori as a part of a scientific project, upper dyspepsia, upper gastrointestinal bleeding, failure to thrive, coeliac disease, suspicion of chronic inflammatory bowel disease and a percutaneous gastrostomy. Seventy-two OGD were carried out in general anaesthesia, 86 in intravenous sedation with midazolam and pethidine and 41 in intravenous midazolam sedation. Complications related to the sedation or to the endoscopy were not observed. Amnesia was reported in 94/95 children who were sedated intravenously with midazolam and pethidine or midazolam alone. Six endoscopies could not be carried out in intravenous sedation because of agitation. In the primary OGD endoscopy revealed a normal mucosa in 121/142 (85%), oesophagitis in four (3%), nodular mucosa in six (4%), gastritis in four (3%) and a duodenal ulcer in one (0.7%). Histology disclosed active or inactive chronic gastritis at the primary endoscopy in 35/69 (51%) of the children with recurrent abdominal pain and antibodies against H. pylori. In children with failure to thrive an avillous duodenal mucosa was seen in 3/32 (9%). A comparison between histological and stereomicroscopical evaluation of the duodenal biopsies revealed agreement in 41/47 (87%). We conclude that OGD is a safe and tolerable procedure in paediatric patients, in whom possible morphological changes are suspected. The indications for an OGD need further evaluation.

A large number of prospective population studies from many countries have described a J- or U-shaped relation between alcohol intake and mortality. Both heavy drinkers and abstainers are at a higher risk of dying from all causes than individuals with light to moderate alcohol intake. This makes information to the public about sensible drinking limits more complex than, eg, that concerning smoking. The present paper aims at identifying upper thresholds for harmless alcohol intake. The review is mainly based on epidemiological evidence concerning somatic morbidity and mortality. It is concluded that the present Danish recommendations--14 drinks per week for women and 21 drinks per week for men--should be maintained. It is emphasized that these limits apply to adults who are at no risk of dependency and that they do not apply to pregnant women. Information about a potentially beneficial effect of a moderate alcohol intake should be reserved for individuals already at risk of coronary events.

In a prospective population study of 7,234 women and 6,051 men aged 30-79 years, information on beer, wine, spirits and tobacco consumption, and on education, income and body mass index were assessed in the period 1976-1978, and the population was followed until 1.1.1988 for mortality. With increasing intake, the wine-mortality risk function steadily decreased from a relative risk of 1.00 for those who never drank wine through 0.51 (95% confidence limits; 0.32-0.81) among those who drank three to five glasses per day. In contrast, neither beer nor spirits consumption was associated with reduced risk. For spirits consumption the relative risk of dying increased from 1.00 among those who never drank to 1.34 (1.05-1.71) among those with an intake of 3-5 drinks per day. Wine drinking showed the same relation to risk of death from cardio- and cerebrovascular disease as to mortality from all causes.

We studied whether somatostatin or its derivative, octreotide, is more effective than placebo in the treatment of bleeding oesophageal varices in a randomised, double-blind trial and a meta-analysis with blinded data analysis and manuscript writing. Patients suspected of bleeding from oesophageal varices and of having cirrhosis of the liver were eligible. Eighty-six patients were randomised; 16 died in each group within six weeks (95% confidence interval (CI) for difference in mortality -19% to 22%). There were no differences between somatostatin and placebo in median number of blood transfusions (8 vs 5, p = 0.07, CI 0 to 4 transfusions) or in numbers of patients who needed balloon tamponade (16 vs 13, p = 0.54, CI -11% to 28%). In a meta-analysis of three trials, involving 290 patients, somatostatin had no effect on survival compared with placebo (p = 0.59, odds ratio 1.16, CI 0.67 to 2.01). For blood transfusions and use of balloon tamponade there was heterogeneity between the trials with no convincing evidence in favour of somatostatin.

Portal hypertensive gastropathy (PHG) as defined by congestive changes in the gastric mucosa owing to increased portal pressure, was first described about ten years ago. Whereas definition and grading of severity are still under debate, there is general agreement that PHG is a new clinical entity. PHG is present in 50-80% of patients with liver cirrhosis. PHG is a major cause of upper gastrointestinal bleeding in patients with portal hypertension (25-90% depending on severity). Presence of portal hypertension is a prerequisite for the development of PHG, and reduction of portal pressure and splanchnic blood flow with beta-adrenergic blockers has shown promising results, but an established medical treatment of PHG does not exist. Trials with new vasoactive drugs are awaited.

Somatomedins or insulin-like growth factors (IGF) are peptides synthesized in the liver. IGFs have different anabolic and metabolic actions and are important in normal growth and development. The concentration of IGF is low in patients with chronic liver disease mainly due to the decreased liver function. Low levels of somatomedins are also seen in patients with growth hormone (GH) insufficiency, renal impairment and malnutrition. GH stimulates the production of IGF-1, and both are part of a negative feed-back system acting on hepatic, pituitary and hypothalamic levels. The basal and stimulated GH concentration is pathologically elevated in patients with chronic liver disease. The total daily secretion is unknown as urinary measurements have only recently been introduced. Alterations in liver IGF receptors in patients with chronic liver disease require still investigation as they may be important for the liver function.

Immunologic evaluations were done on a total of 21 dogs presented with acute blastomycosis. There were significant increases in serum alpha 2-, beta-, and gamma-globulins with decreases in albumin concentration. Serum immunoglobulin G was significantly increased, while immunoglobulin M was decreased. Lymphocyte reactivity was evaluated in 6 dogs with acute blastomycosis. There were significant reductions in lymphocyte reactivity in autologous sera to pokeweed, concanavalin, and phytohemagglutinin stimulation. In addition to decreased reactivity of lymphocytes in dogs with normal lymphocyte counts, 40% of dogs with acute blastomycosis were lymphopenic. Abnormalities in cell-mediated immunity may have a role in the pathogenesis of canine blastomycosis.
