A drunk and disorderly country: a nationwide cross-sectional survey of alcohol use and misuse in Great Britain.

OBJECTIVES: To explore current alcohol drinking patterns, behaviours and attitudes in Great Britain. DESIGN AND SETTING: Independent online cross-sectional survey. PATIENTS AND INTERVENTIONS: Survey of 2221 individuals from a representative panel. MAIN OUTCOME MEASURES AND RESULTS: Excessive alcohol consumption is a widespread problem across Great Britain. Binge-drinking is common among 18-24 year olds, with 19% reporting drinking 10+ drinks on the same drinking day. 'Pre-loading' with alcohol at home before going out was reported by 30% of 18-24-year-old drinkers, of whom 36% get drunk twice or more a month, with 27% having injured themselves while drunk. Among older drinkers, 25% regularly drink to excess, 8% drink seven or more drinks on a typical drinking day and 9% self-reported drink-driving. Male gender was an independent risk factor for heavy (>40 units/week) alcohol abuse (odds ratio 3.05 (95% CI 1.82 to 5.10)). Men (19%) were more likely than women (8%, p<0.001) to report binge-drinking, drink-driving (11% vs 3%, p<0.001), or to have missed work owing to alcohol consumption (12% vs 7%, p<0.001). Young drinkers said they were heavily influenced by overall alcohol price and drink promotions. Increasing average weekly alcohol consumption, age <55 years, male gender, never having been married and being in full-time employment were all independently associated with a history of alcohol-related self-harm. Alcohol abuse was not related to socioeconomic status. CONCLUSIONS: Alcohol abuse remains common across all socioeconomic strata and geographical areas of Great Britain. Minimum pricing strategies and interventions that target cheap on-trade alcohol products seem likely to bring major public health benefits.

Abnormal oesophageal motility in patients with chronic cough.

BACKGROUND: Although gastro-oesophageal reflux is a recognised cause of chronic cough, the role of oesophageal dysmotility is unknown. The aim of this study was to determine the prevalence of abnormal oesophageal motility in a selected group of patients with chronic cough. METHODS: Oesophageal manometry and 24 hour pH monitoring were performed in 43 patients with chronic cough, 34 of whom had symptoms suggestive of gastro-oesophageal reflux. Comparative manometric measurements were made in 21 healthy subjects. RESULTS: Nine patients with chronic cough had normal manometry and 24 hour pH. Of the remaining 34 patients, 11 (32%) had abnormal manometry alone, five (15%) had abnormal 24 hour pH monitoring alone, and in 18 (53%) both tests were abnormal. Only one patient in the control group had manometric abnormalities. CONCLUSIONS: These results point to a previously unrecognised high prevalence of abnormal oesophageal manometry in patients presenting with chronic cough. Oesophageal dysmotility may therefore be important in the pathogenesis of cough in these patients.

Association of adult achalasia and alacrima.

Achalasia is the best described motor disorder of the esophagus. Associations with familial glucocorticoid deficiency and alacrima (triple A syndrome) have been described in the pediatric population, but no attention has been paid to the possibility of this association in adults. Tear production was assessed in 20 patients with achalasia and 20 age- and sex-matched controls. Deficient tears were found in four achalasics compared with none among the controls (P < 0.05). This suggests that some variant of the triple A Syndrome (achalasia, alacrima, and adrenocortical insufficiency) may exist in adult patients with achalasia as well.

[Transitional tumor of the bladder in an teenager. Preliminary note]. / Tumor vesical transicional en una adolescente. Nota preliminar.

Brief report on the case report of a young female diagnosed and treated (TUR) of a low grade transitional vesical tumour. The reason behind this paper is the early presentation of this tumoral species. Although this neoplasia used to be practically anecdotal, this is no longer the case. This fact prompted our concern and urged us to continue to investigate the reasons for vesical tumours having an increasingly higher incidence in our environment. In order to manage these neoplasias will shall merge data from ultrasonography with that obtained from urinary cytology. Cystoscopies shall be avoided as far as possible. References used to prepare this paper come from a brief review of the relevant Spanish urological literature. We believe this to be sufficient to prepare a "Clinical report" type original.

Balloon or bougie for dilatation of benign esophageal stricture?

Ninety-three adult patients with benign esophageal stricture were randomized to receive balloon or bougie dilatation. Eighty-five patients were eligible for analysis and were followed prospectively for a year. Twenty-four patients required repeat dilatation within a year, but 50 patients completed a year's follow-up without further dilatation. The bougie group initially had a better symptomatic result, experiencing significantly less dysphagia at five months, although this difference had disappeared at one year. Eighteen patients in the balloon group required redilatation for symptoms compared with six in the bougie group. The bougie group had a significantly greater increase in their stricture diameter, and this was still present at one year after dilatation. There was no significant difference in safety or patient acceptability. Balloons are probably more costly to use than bougies. Bougie dilatation is to be preferred to balloon dilatation in adults except in special circumstances.

Comparing the efficacy of cisapride and ranitidine in oesophagitis: a double-blind, parallel group study in general practice.

Patients with endoscopically confirmed oesophagitis (n = 49) were treated for 8 weeks with either cisapride (10 mg four times a day) or ranitidine (150 mg twice a day) in a double-blind study in general practice. Mean overall symptom scores fell from 10.8 to 4.5 in the cisapride group and from 9.9 to 4.4 in the ranitidine group over the course of the study. The proportion of patients reporting improvements in individual symptoms in the two treatment groups (cisapride and ranitidine respectively) were: heartburn, 66% and 55%; acid regurgitation, 53% and 47%; epigastric pain, 60% and 52%; satiety, 57% and 47%; bloating, 69% and 71%; belching, 65% and 72%; nausea, 62% and 85%; vomiting, 77% and 66%; poor appetite, 50% and 75%. Improvement in the endoscopic grade of oesophagitis was observed in 66% of patients receiving cisapride and 63% of those receiving ranitidine. It was concluded that cisapride is as effective as ranitidine in relieving the symptoms of oesophagitis and in healing oesophageal erosions.

Oesophagitis is as important as oesophageal stricture diameter in determining dysphagia.

It is a common observation that stricture patients with severe dysphagia may have a wide lumen, while others with a narrow stricture have few swallowing complaints. In 64 patients with benign oesophageal stricture the dysphagia score (determined by questionnaire and by a test meal both based on nine different items of food scored according to their solidity) was compared with the diameter of the stricture measured radiologically by premeasured barium spheres. There was evidence of an association, but the correlation coefficient (r) was 0.544 (p = 0.0001), suggesting that the diameter of the stricture is an important, although not the sole, determinant of dysphagia. Stricture diameter explains 29.6% (r2) of variation in dysphagia score. The patients (mean dysphagia score 71 of a maximum possible 90) were divided into three groups according to the severity of oesophagitis (19 patients had minimal, 22 moderate and 23 severe oesophagitis). Analysis revealed the mean dysphagia score to be 83, 73, 59 in each group respectively. Dysphagia score of each group was significantly different from the others (Kruskal-Wallis test). Relating the dysphagia score to stricture diameter for each group gives correlation coefficient r = 0.379 (p = 0.110) in the minimal oesophagitis group, r = 0.651 (p = 0.001) in the moderate group, r = 0.583 (p = 0.004) in the severe group. If both diameter and severity of oesophagitis are included then 66.0% of the variation can be explained. It is concluded that the degree of oesophagitis is as important as luminal diameter in determining swallowing ability.

Short report: comparison of two orally administered bowel preparations for colonoscopy--polyethylene glycol and sodium picosulphate.

Fifty-nine consecutive patients admitted for colonoscopy were randomized to receive polyethylene glycol or sodium picosulphate. Patients expressed their opinion in a questionnaire and the endoscopists, blinded to the preparation, assessed the cleanliness of different segments of the colon. There was no statistically significant difference in the taste-acceptability of the preparations, frequency of nausea, abdominal pain, peri-anal soreness or sleep disturbance between the two groups. Polyethylene glycol caused vomiting in 13% of patients while this was absent in those who received sodium picosulphate (P less than 0.05). The average number of stools passed was 12.4 in the polyethylene glycol and 8.6 in the sodium picosulphate groups; mean difference 3.8 (95% C.I. 0.7-6.9) with P less than 0.02. The overall cleanliness of the colon was better in the polyethylene glycol group (P = 0.002) as judged by the blinded colonoscopist. There was less delay (P = 0.06) and more completed colonoscopies (P = 0.01) in this group. Polyethylene glycol was a better preparation in all segments of the colon except the rectum. We conclude that polyethylene glycol is the choice of the colonoscopist and should be given to all patients; sodium picosulphate would be a good alternative if patients are intolerant. If a limited colonoscopy or flexible sigmoidoscopy is intended, sodium picosulphate may be preferred because of its acceptable efficacy and slightly advantageous side-effect profile.

Esophageal involvement in Behçet's disease. Is endoscopy necessary?

Twenty patients who were diagnosed as having Behçet's Disease between 1976 and 1990 were asked to attend the dermatology department so that their diagnosis could be reviewed in the light of recently established criteria for the diagnosis of Behçet's disease. Ten patients fulfilled the diagnostic criteria, nine of whom agreed to participate in this endoscopic study. Nine patients underwent upper gastrointestinal endoscopy, three of whom had dyspepsia alone, two had dysphagia and dyspepsia, one had symptoms of acid regurgitation, and the remainder were asymptomatic at the time of endoscopy. One patient had evidence of grade 1 reflux esophagitis, one had an incidental pyloric canal ulcer, and one patient who had severe dysphagia on presentation was found to have a high esophageal stricture with accompanying ulceration. Behçet's disease rarely affects the esophagus but when present can cause marked esophagitis with consequent stricture formation. Since the incidence of esophageal involvement was low (11%), we conclude that unless the patient had marked esophageal symptoms there is no indication for routine endoscopy of patients with Behçet's disease.

A new dysphagia score with objective validation.

Patients' accounts of their eating capacity correlate reasonably well with their observed performance, but they do not exactly match each other. This can be attributed to patients' inaccurate estimation of eating ability and the inconstant nature of dysphagia. Therefore, we advocate a combined score in clinical trials. However, for clinical practice, a quantitative assessment of the patient's account is quicker, more convenient, and sufficiently accurate. The advantage of a numerical score is obvious in clinical trials because of its statistical versatility, and may also be desirable in certain cases in clinical practice.

Effects of carbohydrate type on postprandial blood pressure, neuroendocrine and gastrointestinal hormone changes in the elderly.

Previous studies have demonstrated that blood pressure falls postprandially in fit elderly subjects, the greatest changes occurring after meals with a high carbohydrate content. To evaluate the influence of the type of carbohydrate on postprandial blood pressure, the effects of equivalent energy content (2.4 MJ) high complex (starch) and high simple (monosaccharide) carbohydrate meals were studied in seven healthy elderly subjects. Blood pressure, heart rate, autonomic function, plasma catecholamines, insulin and neurotensin levels were measured pre- and postprandially. Greater falls in supine and erect systolic blood pressure occurred after the high simple than the high complex carbohydrate meal (p less than 0.05). No differences were found in supine or erect diastolic blood pressure, heart rate or in any of the biochemical parameters measured between the meal types. It is concluded that a simple carbohydrate meal results in a greater postprandial fall in blood pressure than an equivalent energy complex carbohydrate meal in the elderly, although the mechanisms for these changes are unknown.

The effect of caffeine on postprandial hypotension in the elderly.

In a double-blind, randomized trial the effects of caffeinated and decaffeinated drinks on postprandial hemodynamic and neurohumoral changes were studied in seven fit, elderly subjects after a standard 2.4MJ meal. There was a significant difference in supine postprandial systolic blood pressure between the placebo and caffeine phases (P less than 0.01); at 60 minutes, supine systolic blood pressure had fallen 14 mmHg [95% confidence interval (CI)-7 to-21 mmHg, p less than 0.01) after placebo, but was unchanged after caffeine (+9 mmHg, CI 0 to 18 mmHg, NS]. Similar differences between placebo and caffeine were seen in erect systolic and diastolic blood pressure (P less than 0.01), although orthostatic tolerance was maintained throughout each study period. Postprandial plasma noradrenaline levels were higher (P less than 0.02) and the increase greater (P less than 0.02) after caffeine than after placebo. Caffeine administered at the end of a standard test meal prevents the postprandial fall in blood pressure in fit, elderly subjects. The clinical relevance of this finding has yet to be determined, but it may offer a simple remedy for patients with symptomatic postprandial hypotension.
