Gamma-hydroxybutyric acid (GHB) is no longer used as an anaesthetic induction agent because of the high incidence of myoclonic seizures and vomiting. However, it is used occasionally in Europe for the treatment of narcolepsy, alcohol dependence and opiate dependence. Since the early 1990s, GHB has become a drug of abuse in youths for its euphoric, sedative and anabolic effects. Common adverse effects include a rapid onset of drowsiness, nausea, vomiting, myoclonic seizures and coma of short duration. Clinicians should be alert for these adverse effects and consider the possibility of GHB abuse in young adults with unusual clinical presentations in the emergency department.

Esophageal perforation after anesthesia is rare. It is usually secondary to esophageal instrumentation. Only one case of barogenic rupture after regional anesthesia has been reported. We report two additional cases and present possible mechanisms for this unusual entity. Neither patient had anatomic abnormalities by history or preoperative endoscopy. However, both patients and the previously reported patient had esophageal dysmotility resulting from advanced age, alcoholism, intraoperative medications, and preexisting disease. Each patient experienced at least one episode of emesis with subsequent perforation of the distal one third of the esophagus. The previously reported patient died; both of our patients underwent successful surgical repair and are alive 2 years later. Intraoperative or postoperative emesis in patients with esophageal dysmotility appears to be the principal factor causing esophageal rupture after regional anesthesia. Prevention of nausea and vomiting and recognition of this high-risk population may minimize this complication in the future.

Mallory-Weiss Syndrome (MWS) lesions account for up to 15 per cent of upper gastrointestinal bleeding episodes. Typically these lesions present as a consequence of vomiting that is often associated with alcoholism. Recently other conditions such as pregnancy, migraine, hiatal hernia, gastric ulcer, biliary disease, and various medications have been associated with MWS. We report on a 32-year-old male who developed a MSW lesion after a prolonged period of swimming followed by an extended commercial airplane flight. The hemodynamic changes associated with swimming (increased central distribution of blood volume) and the pressure changes in commercial aircraft (a reduction of 0.3 atmospheres of pressure) are discussed. We conclude that the combination of these factors contributed to the development of a MWS lesion and gastrointestinal bleeding in this patient. We recommend that both air travel and athletic activities be considered as possible contributing factors in the evaluation of the cause of new-onset gastrointestinal bleeding.

The case is described of a 32-year-old man suffering from alcoholism who came to the Emergency Unit with vomiting, fever and sharp epigastric pain irradiating to the chest and upper abdomen. A diagnosis of acute pancreatitis was made after high amylase and lipase levels were observed and the results of computed tomography scan revealed images typical of acute pancreatitis. Findings upon admission and after the initial 48 hours did not correlate with a severe or complicated course according to Ranson's criteria. On the third day after admission he suddenly developed decreased vision. A fluorescein angiogram showed arteriolar occlusion, retinal and choriocapillary ischaemia. Purtscher's retinopathy was suspected. After 4 weeks, the patient had recovered from acute pancreatitis, ophthalmoscopic examination showed normal results, and visual acuity had almost returned to normal. Activation of complement in acute pancreatitis could account for many haematologic acute disorders due to leucocyte emboli or other complement-mediated aggregates. Coagulation abnormalities may range from isolated intravascular thrombosis to severe disseminated intravascular coagulation. Purtscher's retinopathy, due to microembolizations in the choroidal and retinal arterioles, should be included among the various systemic effects of acute pancreatitis. This visual disorder is a rare systemic manifestation of acute pancreatitis which was not correlated to a severe or complicated clinical course. Treatment of these ocular complications remains to be established and outcome, therefore, depends upon resolution of the pancreatic disease.

Wernicke's encephalopathy (WE) is most commonly associated with alcoholism, although other causes have also been implicated. In the years 1994-1997, 9 patients with no history of alcohol abuse presented with acute signs of ophthalmoplegia or nystagmus and ataxia which resolved within 48 h after intravenous thiamine. There were 7 women and 2 men aged 17-57 (7 below the age of 30). Precipitating events included vomiting 2, drastic weight-reducing diet 2, renal colic in a postpartum woman 1, colonic surgery 2 and chronic hemodialysis 1. In 2 patients there was no obvious precipitating event but their history was suggestive of a genetic predisposition. Mental changes were slight or absent in all patients and all of them made good functional recovery. These cases suggest that the diagnosis of WE should be considered more often in nonalcoholics in various clinical settings.

A case of alcohol withdrawal occurred in a patient affected by cancer of the oral cavity is reported. The patient underwent resection of the floor of the oral cavity, partial glossectomy mandibulectomy and neck dissection; reconstruction was done using microsurgical forearm radial flap. The patient didn't refer his alcohol dependence before operation and withdrawal symptoms with agitation, tachycardia, tachypnea, tremors and vomiting appeared during his postoperative recovery in intensive care where the patient was unable to take any alcohol. A therapeutic plan to use in patients operated for oral cancer with alcohol withdrawal (92% association of oral cancer with alcohol dependence) is reported.

Ondansetron is a selective 5-hydroxytryptamine(3) (5-HT(3)) receptor antagonist that has been introduced to clinical practice as an antiemetic for cancer treatment-induced and anesthesia-related nausea and vomiting. Its use under these circumstances is both prophylactic and therapeutic. It has a superior efficacy, safety and pharmacoeconomic profile compared with other groups of antiemetics, namely antidopaminergics, antihistamines and anticholinergics. However, its place in the management of anticipatory and delayed vomiting in cancer treatment and as a rescue antiemetic in surgical patients needs to be further explored. Furthermore, recent animal and human research also reflects its possible novel application in the treatment of other disease states, such as alcoholism, cocaine addiction, opioid withdrawal syndrome, anxiety disorders, gastrointestinal motility disorders, Tourette's syndrome and pruritus. This review revisits the widespread physiological and pathological effects of 5-HT and discusses both the basic science literature and the clinical developments responsible for the conventional and novel uses of ondansetron. In addition, new discoveries relating to the effects of ondansetron on other receptors/channels and their possible therapeutic applications are presented.

During the two last decades, several epidemiological studies have been conducted on bulimia nervosa. According to recent studies, prevalence rates were estimated to be 1%. There are a very few studies on eating behaviour conducted in Arab countries. The aims of the current study were to assess prospectively the prevalence of Bulimia Nervosa and its characteristics in a Moroccan context in a randomly selected and representative sample of students attending six secondary schools in Casablanca. A second group composed of the students of the French secondary school of Casablanca was included in the survey in order to verify the influence of socio-cultural factors. Subjects completed a sociodemographic questionnaire and the Bulimic Investigatory Test of Edinburgh (BITE), a 33-item self-report measure of both the symptoms and severity of bulimia nervosa. A score of 25 or higher suggests a bulimic syndrome; 2,044 subjects returned their questionnaires (participation rate = 75.8%). The group of Moroccan school included 1,887 subjects and the French school 157 subjects. Females were preponderant (59%). The mean age was 18.3 +/- 1.2 years (15-22 years). For the first group, at least one substance was taken by 290 (15.3%) students: 12.7% were addicted to tobacco and 5.7% consumed occasionally alcohol. 16.3% reported a familial history of disturbed eating behaviour. According to the BITE, the overall prevalence of bulimia was 0.8% (1.2% in female and 0.1 in male subjects). The mean age of bulimic subjects was 18.6 +/- 1.7 years (16-24 years). The only male case in our sample was aged 24 years, without personal nor familial psychiatric history, consumed regularly tobacco and alcohol. His BITE symptoms score was 20 and severity score was 17, the highest score in our sample. Analyses of correlates of bulimia nervosa in the Moroccan sample showed that the group of bulimic subjects did not differ from the non bulimic with regard to any sociodemographic characteristics except sex: the female sex was predominant (p < 0.005) with 14 cases, the prevalence of bulimic syndrome was 1.2% among girls. This prevalence was 0.1% among boys. The bulimic subjects have regularly used different compensatory behaviours to control their weight: 6 (33.3%) used appetite suppressants, 3 (16.6%) used diuretics and 4 (22.2%) were engaged in self-induced vomiting. In the group of the french school, the prevalence of bulimia was 1.9% in the whole sample (3.4% among girls and no case among boys). These results are comparable to those reported recently in occidental countries and in an Egyptian study. However, the prevalence of bulimic syndrome in our sample was lower to those reported in countries with similar culture. The elevated prevalence of 10% reported in a tunisian study could be explained by the composition of the sample (medical students, aged 22-28 years) and the cut-off point for the BITE was determined to be 20 without taking into account severity criteria. A South African survey, conducted on 1,435 college students representing South Africa's ethnically and culturally diverse population comparable to our sample regarding the age (17-25 years), found a prevalence of 5% with a cut-off of 25 in the BITE. The majority of epidemiological community-based studies estimated the prevalence of bulimia nervosa to be 1 to 3% according to the diagnostic instruments used (self-report questionnaires versus clinical interviews) and the diagnostic criterias operationalized (DSM III, III-R or IV). The rate of occurrence of this disorder in males usually one-tenth of that in females was more decreased among our sample. However, the prevalence among males was comparable to the data of literature. Except the sex, we did not find other risk factors identified in the previous papers. Although in the bulimic group, we noted a higher rate of substance abuse (26.6% versus 15.2%, p > 0.5), familial histories of disturbed eating behaviour (26.6% versus 16.2%, p > 0.3) and less regular practice of sportive activity (72.2% versus 92.3%, p > 0.1), these differences are not statistically significant. The review of the literature identified at least 5 domains associated to bulimic disorder: parental problems (lower parental contact or separation, disruptive events), vulnerability to obesity, parental psychiatric disorder (alcoholism, depression), sexual or physical abuse and a premorbid psychiatric disorder. With the enormous media coverage and the globalisation of the media, cultural differences are disappearing. In order to estimate the prevalence of bulimia nervosa in the Moroccan population and to identify the risk factors, further epidemiological community-based studies using structured psychiatric interviews are required.

Aspiration of oro-pharyngeal secretions and gastric content is the most frequent cause of formation of primary lung abscess. A compromised mental status (e.g. alcoholism, sedatives, stroke) and esophageal dysfunction (e.g. herniation, vomiting) are important risk factors. Aspiration pneumonia presents as a subacute disease and is usually not distinguishable from other causes of pneumonia, until typical radiological signs of cavitation and putrid sputum appear 8 to 14 days after the initial event of aspiration. Anaerobic bacteria play a pivotal role in an almost exclusively mixed spectrum of causative organisms. Aerobic pathogens are also frequently isolated, but whether they are an active part of infection or merely represent colonizers remains unclear in many instances. Differential diagnosis includes bronchial neoplasms, either as necrotizing carcinoma or as the cause of poststenotic cavernous pneumonia, other infectious diseases like tuberculosis, Pneumocystis carinii pneumonia or endocarditis with septic metastases, and lung artery embolism or vasculitis (M. Wegener). Fiberoptic bronchoscopy is extremely helpful in determining cause and etiology of the disease and should be carried out in all patients presenting with cavernous lung lesions. Bacteriological sampling should be performed using protected specimen brushing (PSB) technique. Broncho-alveolar lavage might serve as a less expensive but also less sensitive alternative measure. Since anaerobic bacteria resemble ubiquitous commensals of the oral cavity, sputum is of no use in anaerobic culture. Principal therapeutic strategy is antibiotic therapy for an extended period, usually four weeks to four months, unless radiologic changes and as well laboratory as clinical indicators of infection are completely resolved. Clindamycin, optionally supplemented with a second or third generation cephalosporin and Ampicillin/Sulbactam proved equally effective in treating aspiration pneumonia and primary lung abscess. The role of Moxifloxacin and other new flouroquinolones with their favorable pharmacodynamics is currently evaluated. Provided that antibiotics are prescribed for a sufficient period of time and patients' compliance is ensured, surgical procedures are limited to a negligible number of complications, e.g. recurrent severe hemoptysis, empyema or broncho-pleural fistula.

The Mallory-Weiss-syndrome is an upper gastrointestinal haemorrhage due to longitudinal mucosal lacerations in the oesophagogastric junction. The mucosal lacerations occur as a sequel of vomiting or any other increase in intraabdominal pressure and account for up to 15% of all upper gastrointestinal bleedings. If death is due to a bleeding Mallory-Weiss-tear, however, massive blood stains on the corpse and around it frequently give rise to the suspicion of an unnatural cause of death. For this reason, autopsy is usually indispensable to elucidate the circumstances in which death occurred. The authors carried out a retrospective analysis of 5958 autopsies performed between 1997 and 2001 at the Institute of Legal Medicine, University of Hamburg, in order to identify all cases of Mallory-Weiss-syndrome as cause of sudden, unexpected death. The results (9 cases, amounting to 0.15% of all autopsies) suggest that Mallory-Weiss-syndrome is probably much more common as a cause of sudden death than previously described. Regarding epidemiological aspects, men clearly predominate; the average age was 48 years. It should also be stressed that in 8 of the 9 cases there was a previous history of chronic alcohol abuse.
