The discovery of multiple subtypes of the serotonin 5-HT receptor has generated enormous interest over the past few years. Possibly the most exciting, in terms of psychiatric clinical practice, appeared to be the 5-HT3 receptor. Early animal studies suggested that the 5-HT3 receptor antagonists, in addition to their well recognised antiemetic use, might be clinically useful in a number of areas. These included anxiety disorders, psychotic disorders, drug and alcohol abuse disorders, depressive disorders, cognitive disorders, the treatment of pain and the treatment of irritable bowel syndrome. With the exception of antiemetic actions, this review examines these potential therapeutic areas carefully, paying particular attention not only to the animal literature, but to the clinical studies which have resulted from these initial findings. Unfortunately, studies in many of these therapeutic areas have not lived up to their initial promise. Indeed, no clinical studies have yet clearly demonstrated the usefulness of 5-HT3 receptor antagonists in the treatment of CNS disorders. Nonetheless, in view of the absence of published results from double-blind, placebo-controlled studies in many of these therapeutic areas, further research would be useful in confirming the effectiveness, or otherwise, of this group of compounds.

15 to 30% of the patients with chronic pancreatitis develop an inflammatory mass in the pancreatic head. The leading symptoms of these patients are severe upper abdominal pain and complications of the surrounding organs. From 1969 to 1995, 380 patients were treated with a duodenumpreserving pancreatic head resection. The cause of the disease was alcohol abuse in 81%. 93% of the patients suffered from severe pain with recurrent pain attacks. CT-scan revealed enlargement of the pancreatic head (> 4 cm in diameter) in 79% of the patients. 83% of the patients had an impaired exocrine pancreatic function; 48% of the patients had an impaired glucose tolerance or were diabetic. The hospital mortality was 0.8%; 5% of all patients had to be reoperated. The mean duration of the hospitalization was 13.9 days. 89% of the patients showed an unchanged endocrine function in the early postoperative course. The glucose metabolism was improved in 9%, 2% had a deteriorated function. The duodenum-preserving pancreatic head resection is a procedure with a low postoperative mortality and morbidity without deterioration of the endocrine pancreatic function.

A case of severe opioid toxicity is described in a 52-year-old cancer patient. The patient presented with classical clinical features of central hyperexcitability associated with opioid toxicity: delirium, myoclonus, hallucinations, hyperalgesia, and a possible seizure. This patient had a background of severe psychosocial distress and somatization in addition to a history of benzodiazepine dependence and alcohol abuse. The occurrence of opioid toxicity in this patient highlights the risks of a unidimensional approach to cancer pain, which ignores the non-organic components of pain, such as psychosocial distress, which will not respond to escalating doses of opioid medication.

This study evaluated post-treatment performance and quality of life (QOL) outcome in head and neck cancer (HNC) patients treated with organ preservation, intensive chemoradiotherapy (FHX). Participants were 47 Stage II-IV HNC patients with no evidence of disease at least one year post-completion of organ preservation, concomitant FHX treatment. Patients were assessed via a semi-structured in-person interview, standardized measures of QOL (FACT-H&N, CES-D), performance (PSS-HN) and patients' perception of residual side effects. Disease, treatment and toxicity data were retrieved from medical charts and protocol records. The most salient performance impairment was inability to eat a normal solid food diet, with 50% of patients able to eat soft foods or take liquids only. This specific functional deficit was not related to global QOL, nor to specific quality of life dimensions. Dry mouth, the most frequent and severe residual effect, was not associated with outcome diet, depression or QOL. Residual pain, seen in only 15% of patients, appeared to influence both functional and QOL parameters as well as being a marker for other troublesome symptoms. Twenty-three per cent of patients were depressed; depression was associated with past problems related to alcohol abuse. Decreased QOL and increased depressive symptomatology were related to total number and severity of residual effects. The data highlight the importance of systematic study of QOL dimensions and caution against making assumptions about patients' experience of particular disease and treatment sequelae.

Chronic pancreatitis is a lifelong illness for patients and a persistent medical challenge for the gastrointestinal physician. Most cases are induced by alcohol abuse. This leads to a process of recurrent injury, chronic fibrosis and subsequent pain, pancreatic ductal scarring, and dilatation. The surgical management of these associated complications as seen in the patient presented in this report will be discussed in the context of the current surgical literature.

The abuse of alcohol causes health and social problems, such as sickness, death, injury, pain, suffering and crime. These harms impose an economic burden on society. Resources are used or foregone as a consequence of alcohol abuse. This article provides an estimate of the economic cost of alcohol abuse in Ontario in 1992. It uses the cost-of-illness method, in particular, the human-capital approach to estimate the prevalence-based economic costs of alcohol abuse. This methodology is consistent with international guidelines formulated at the 1994 International Symposium on Economic and Social Costs of Substance Abuse. The direct and indirect economic costs of alcohol abuse are identified and estimated. The total economic cost of alcohol abuse, from a societal perspective, is estimated to be US$2261.10 million in Ontario in 1992.

Opioid drugs play important roles in the clinical management of pain, as well as in the development and treatment of drug abuse. The mu opioid receptor is the primary site of action for the most commonly used opioids, including morphine, heroin, fentanyl, and methadone. By sequencing DNA from 113 former heroin addicts in methadone maintenance and 39 individuals with no history of drug or alcohol abuse or dependence, we have identified five different single-nucleotide polymorphisms (SNPs) in the coding region of the mu opioid receptor gene. The most prevalent SNP is a nucleotide substitution at position 118 (A118G), predicting an amino acid change at a putative N-glycosylation site. This SNP displays an allelic frequency of approximately 10% in our study population. Significant differences in allele distribution were observed among ethnic groups studied. The variant receptor resulting from the A118G SNP did not show altered binding affinities for most opioid peptides and alkaloids tested. However, the A118G variant receptor binds beta-endorphin, an endogenous opioid that activates the mu opioid receptor, approximately three times more tightly than the most common allelic form of the receptor. Furthermore, beta-endorphin is approximately three times more potent at the A118G variant receptor than at the most common allelic form in agonist-induced activation of G protein-coupled potassium channels. These results show that SNPs in the mu opioid receptor gene can alter binding and signal transduction in the resulting receptor and may have implications for normal physiology, therapeutics, and vulnerability to develop or protection from diverse diseases including the addictive diseases.

The authors prospectively assessed symptoms induced by the interruption of antidepressants in 16 patients (11 women and 5 men), aged from 33 to 85 years (mean = 52.4 +/- 16.4), treated with antidepressants since at least two weeks. All patients were free of alcohol abuse or dependence disorder and of other dependence to psychoactive substances. None of them presented medical illness. Diagnosis were made by separate evaluations by two authors and confirmed with a semistructered assessment instrument: the Schedule for Affective Disorders and Schizophrenia (Lifetime Version). All patients were submitted to a brutal discontinuation of their antidepressant agent. Patients were assessed twice, before the interruption of the antidepressant, and 72 hours later. Effects of antidepressant interruption were assessed by several means. Modification of anxiety and depression were evaluated using the Montgomery Asberg Depression Rating Scale (MADRS) and the Hamilton Anxiety Scale. Symptoms of withdrawal were assessed with Cassano and al.'s scale SESSH including an evaluation of anxiety, agitation, irritability, anergy, difficulty on concentrating, depersonalization, sleep and appetite disorders, muscle pains, nausea, tremor, sweating, altered taste, hyperosmia, paresthesias, photophobia, motor incoordination, dizziness, hyperacousia pain, delirium. Fourteen of the 16 patients (87.5%) presented modifications of their somatic or psychic state 3 days after the interruption of the antidepressant treatment. Most frequent symptoms were: increase in anxiety (31%), increase in irritability (25%), sleep disorders (19%), decrease of anergia and fatigue (19%). Mean scores of anxiety and depression were not significantly modified by the withdrawal. Following TCAs interruption (7 patients) most frequent symptoms were sleep disorders; increase in anxiety, nausea. Among patients withdrawn from SSRIs (6 patients), most frequent symptoms were increase in anxiety, increase in irritability, headache. Patients also presented a decrease of nausea, and of anorexia.

From 1978 to 1995, 120 patients (105 males, 15 females, mean age: 46 years) underwent pancreatico jejunostomy (PJ) for chronic pancreatitis (CP). Alcohol abuse was presented in 105 cases (87.5%). PJ was the unique procedure in 67 cases; it was associated with a biliary or a duodenal diversion in respectively 38 cases and 5 cases. In ten cases, three diversions were performed. Postoperative mortality was 1.6% (n = 2), postoperative morbidity was 10% (n = 12). Mean hospital stay was 16 days. Fifteen patients (13%) required a second operation some years subsequent to the PJ, due to the progress of the CP or alcohol abuse. In the late postoperative course 22 deaths occurred (18.5%), 8 of them were directly related to alcohol abuse. Mean follow-up was 7 years. Good and medium results for pain were evaluated to 92%, but the progression of exocrine or endocrine pancreatic insufficiency indicates that wirsung decompression was insufficient to stop the progressive sclerosis. In conclusion, PJ was our preferred surgical procedure in CP treatment, when the wirsung was dilated.

The aim of the study was to study factors related to anxiety, depression, and suicidal ideation among HIV-seropositive heterosexuals soon after being tested for their HIV status for the first time. Anxiety, depression, and suicidal ideation were assessed among 51 HIV-seropositive heterosexual men and women with various stages of HIV infection. All assessments were done between 4 and 6 weeks after revelation of positive serostatus. Psychosocial variables such as quality of family relationships and substance use and sociodemographic details such as gender, income, education, and residence were studied for their association with psychiatric morbidity. Illness details studied for their association with psychiatric morbidity included stage of HIV infection, spouse's HIV status, presence of physical illness, and pain. Depression was present in 40% and anxiety in 36% of the sample. Serious suicidal intent was seen in 14%. Multiple regression analysis indicated that presence of pain, concurrent alcohol abuse, poor family relations, and presence of AIDS in the spouse were significant factors associated with depression, anxiety, and suicidal ideation.
