Magnesium deficiency can occur in congestive heart failure, after diuresis with furoxemide, ethacrynic acid and mercurials, and with digitalis intoxication, diabetic acidosis, acute and chronic alcoholism, delerium tremens, cirrhosis, malabsorption syndromes, protracted postoperative cases, open heart surgery, the diuretic phase of acute tubular necrosis, and with hypoparathyroidism, primary aldosteronism, juxta-glomerular hyperplasia and pancreatitis. Two cases of serious ventricular arrhythmias associated with magnesium depletion are described. Clinical manifestations are vague but center around neurologic symptoms such as weakness, tremors, stupor, coma, nausea, vomiting and anorexia. Serious cardiac arrhythmias also occur with magnesium depletion. Magnesium appears to be very useful in hypomagnesemic or digitalis-toxic tachyarrhythmias. Magnesium may also be valuable in normomagnesemic tachyarrhythmias. Ten to fifteen milliliters of a 20 percent magnesium sulfate solution, given intravenously over 1 minute, followed by a slow 4 to 6 hour infusion of 500 ml of 2 per cent magnesium sulfate in 5 per cent dextrose in water is recommended. Recurrence of arrhythmias is common and a second infusion of magnesium sulfate may be necessary. Hypermagnesemia occurs frequently in renal insufficiency, and magnesium therapy may then be contraindicated. Serum levels above 5.5 meq/liter should be avoided. Loss of deep tendon reflexes and a decrease in respiratory rate can be used as guides to magnesium therapy. A plea is made for frequent analysis of serum magnesium so that more knowledge can be gained regarding this important biologic element in cardiovascular disorders.

Three cases of benign pancreatic ascites have been added to 94 cases reviewed from the literature. Common characteristic of this syndrome were chronic alcoholism, intermittent abdominal pain, nausea, vomiting and considerable weight loss which occurred despite fluid accumulation. Markedly elevated protein and amylase levels in the ascitic fluid, hyperamylasemia and hypoalbuminemia were the major diagnostic clues as to the pancreatic origin of ascites. Predominant pathological findings were chronic pancreatitis with or without pseudocysts, pancreatic duct disruption, lesion which were considered to be the major pathogenic factor besides lymphatic obstruction by leaking pancreatic juice into the peritoneal cavity. Early laparotomy for diagnosis and treatment is essential. ERP might be of great value in diagnosis.

Selective serotonin reuptake inhibitors (SSRIs) are a recently developed class of drugs with significantly greater antidepressant efficacy than placebo. Generally, in double-blind comparative trials, all SSRIs demonstrated antidepressant efficacy similar to that of the 'standard' tricyclic antidepressants amitriptyline and imipramine; a meta-analysis of controlled trials found the efficacy of the SSRIs to be equivalent to that of the 2 tricyclics. Nevertheless, because of small patient numbers included in most studies that compare SSRIs with other antidepressants, no definitive statements about relative efficacy can be made. In these studies it is simply possible to state that no statistically significant differences were identified between SSRIs and the comparative antidepressants. Importantly, differences in clinical characteristics exist between the SSRIs-differences in elimination half-life (t1/2 beta) between fluoxetine and/or its metabolite (total t1/2 beta = 330 hours) and other SSRIs (t1/2 beta range = 15 to 30 hours), for example. This has implications in terms of potential drug interactions and must be considered when patients have to be switched to treatment with monoamine oxidase inhibitors. Studies with fluvoxamine have been conducted in both in- and outpatients, whereas trials with other SSRIs have been confined largely to outpatient populations. Fluvoxamine has been associated with a high incidence of nausea (37%), although this may have resulted from high initial dosages (rather than upward dose titration protocols) used in early trials. Of further interest, fluoxetine doses of 20mg may be sufficient to produce a satisfactory antidepressant response, and this SSRI may be particularly useful in patients with chronic retarded depression. More clinical data are required before the efficacy of sertraline and citalopram relative to standard antidepressants can be clearly defined. Preliminary data indicate that SSRIs are effective in the treatment of panic disorder, obsessive-compulsive disorder (OCD), eating (e.g. anorexia and bulimia) and personality disorders (e.g. anger, impulsiveness) and substance abuse (e.g. alcoholism); early results with fluvoxamine in the treatment of panic disorder and OCD, and with fluoxetine in the treatment of bulimia, personality disorders and alcohol abuse, have been encouraging. SSRIs have a more favourable tolerability profile than tricyclic antidepressants and, unlike the tricyclics, are not associated with anticholinergic adverse effects, sedation, cardiotoxicity or weight gain. SSRIs are associated with a relatively high incidence of nausea, particularly if high doses are used at the start of treatment. However, the incidence of nausea appears to decrease as treatment is continued.(ABSTRACT TRUNCATED AT 400 WORDS)

A 58-year-old chronic alcoholism patient, who complained of epigastric discomfort, nausea, and frequent loose stool was diagnosed as strongyloidiasis accompanied by duodenal ulcer. The symptoms first appeared two years ago and aggravated during the recent 3 months, and he lost 4 kg of his body weight. Stool examination revealed rhabditoid nematode larvae, which were confirmed as those of Strongyloides stercoralis after cultivation of them to filariform larvae. At duodenoscopy, duodenal ulcer was found. The patient was treated with albendazole (200 mg, bid, for 14 days) for strongyloidiasis and with colloidal bismuth sulfate (240 mg, bid, for 6 weeks) for duodenal ulcer. After the medication, the symptoms of loose stool and epigastric discomfort were much improved and he was discharged with no clinical problems. This is an interesting case which suggests that S. stercoralis infection could be related with ulceration of the duodenal mucosa.

More than 35,000 alcoholics have received chemical aversion (emetic therapy) in at least 75 settings worldwide since the 1930s. This consummatory aversion (CA) treatment, which pairs ethanol ingestion with emetically induced nausea, incorporates the highly efficient variety of learning known as taste aversion (TA) conditioning. The CA literature indicates that emetic therapy should induce conditioned alcohol aversions in many alcoholics. Such aversions have been widely reported by clinicians and have been confirmed by recent psychophysiological evidence. Long standing evidence of treatment effectiveness is found in the results of private hospitals which have consistently produced 1-yr abstinence rates approximating 60%. Diminished alcohol craving is a frequently reported benefit. Few experimental evaluations have been completed, as is generally the case for all alcoholism treatments, but those which used methodologically sound temporal parameters during conditioning have supported the clinical efficacy of emetic therapy. The clear need for more definitive research notwithstanding, there are compelling indications that emetic therapy is a useful component of multimodal treatment within certain alcoholic populations. However, its availability is severely limited. Many alcoholics could probably benefit from expanded treatment availability. The time is ripe for a reevaluation of resistances to the clinical use of emetic therapy alcoholism treatment.

The syndrome of water intoxication may occur in psychiatric patients and various hypotheses regarding its aetiology have been postulated. Twenty-seven patients in Woodbridge Hospital were found to have this syndrome. The aim of the study was to describe the clinical and biochemical findings of this group of patients. 70.4% had schizophrenia, 25.9% had mental retardation and 3.7% had a history of alcohol dependence. Many of them were on antipsychotic medication. The symptoms of water intoxication included polyuria, nausea, tremors, weight gain, disorientation, coma and fits. A majority of the patients had hyponatraemia during the acute stages and the osmolality of urine and plasma were correspondingly low. A few patients had abnormalities in electroencephalogram and computerised axial tomography of brain. The management of patients with water intoxication is discussed briefly.

Differences in the pharmacokinetics of alcohol absorption and elimination are, in part, genetically determined. There are polymorphic variants of the two main enzymes responsible for ethanol oxidation in liver, alcohol dehydrogenase and aldehyde dehydrogenase. The frequency of occurrence of these variants, which have been shown to display strikingly different catalytic properties, differs among different racial populations. Since the activity of alcohol dehydrogenase in liver is a rate-limiting factor for ethanol metabolism in experimental animals, it is likely that the type and content of the polymorphic isoenzyme subunit encoded at ADH2, beta-subunit, and at ADH3, the gamma-subunit, are contributing factors to the genetic variability in ethanol elimination rate. The recent development of methods for genotyping individuals at these loci using white cell DNA will allow us to test this hypothesis as well as any relationship between ADH genotype and the susceptibility to alcoholism or alcohol-related pathology. A polymorphic variant of human liver mitochondrial aldehyde dehydrogenase, ADLH2, which has little or no acetaldehyde oxidizing activity has been identified. Individuals with the deficient ALDH2 phenotype do not have altered ethanol elimination rates but they do exhibit high blood acetaldehyde levels and dysphoric symptoms such as facial flushing, nausea and tachycardia, after drinking alcohol. Because acetaldehyde is so reactive, it binds to free amino groups of proteins including a 37 kilodalton hepatic protein-acetaldehyde adduct and may elicit an antibody response. We would predict that individuals who have low ALDH2 activity because of liver disease or because they have the inactive ALDH2 variant isoenzyme might form more protein-acetaldehyde adducts and elicit a greater immune response. These adducts may represent good biological markers of alcohol abuse and may also play a role in liver injury due to chronic alcohol consumption.

The so-called Oriental flushing reaction associated with ingestion of small amounts of alcohol was antagonized by combined antihistamine administration. In stage one of the study, the flushing reaction to low doses of alcohol was produced in Orientals. Most subjects experienced a cutaneous flush, an increase in skin temperature, a decrease in blood pressure, an increase in pulse rate and subjective symptoms such as dizziness, sleepiness, anxiety, headache, generalized weakness and nausea. Before the administration of alcohol, one-half of the subjects were given 50 mg of diphenhydramine (H1 receptor antagonist) and 300 mg of cimetidine (H2 receptor antagonist). The second half received placebo tablets. The clearest difference between the antihistamine group and placebo group was in the skin flushing reaction. The antihistamine group showed a significant reduction in the skin flush. The antihistamine also neutralized the systolic hypotension induced by the administration of alcohol. The possible importance of histamine in the expression of sensitivity to alcohol is considered. The relevance to genetic susceptibility for development of alcoholism is discussed.

The Oriental flushing reaction is an adverse response to alcohol that appears to be genetically determined. In this study, the Oriental flushing reaction that was produced with ingestion of small amounts of alcohol was antagonized by antihistamine administration. A group of 17 subjects was tested. Each subject received placebo, diphenhydramine 50 mg (H-1 receptor antagonist), and cimetidine 300 mg (H-2 receptor antagonist) singularly and in combination. Alcohol was then administered orally. Most subjects given placebo experienced the typical flushing reaction that included a cutaneous flush, increase in skin temperature, decrease in blood pressure, increase in pulse rate and subjective symptoms such as dizziness, sleepiness, anxiety, headache, generalized weakness, and nausea. The flush, temperature and systolic hypotension were significantly blocked by the combined antihistamine administration. Cimetidine given alone blocked the flush, temperature increase, and systolic hypotension significantly more than diphenhydramine but less than the combined antihistamines. Diphenhydramine was similar to placebo in its effect on the flushing reaction. The role of histamine in the expression of tolerance to alcohol is not known. Antihistamine antagonism of the adverse flushing reaction suggests that histamine receptors may participate in the intolerance to ethanol in Orientals. Histamine may be an important protective factor in the low prevalence of alcoholism in Orientals.

Children who were born in the early 1980s in the Stockholm suburb that was studied had a home environment that may be described as follows. The material standards in the area were good, the dwellings were spacious and modern, the outdoor environment was pleasant for children and the municipal service facilities were well developed. The transport services to the city are frequent, comfortable and convenient. In a typical case, the parents are about 30 years old, they are of old Swedish stock and are living together, married or unmarried. They received a good education and usually also occupational training. Generally, both parents have a job outside the home. In quite a few such cases the mother has shift- or nightwork. Although both parents have jobs, the family surprisingly often has financial problems. Thus more than one family in five needed financial assistance from the authorities. The financial difficulties may be due to illness and addiction in the parents. About one in ten of the mothers has been hospitalised for a chronic somatic disease and about one in ten of the fathers is in the records for alcoholism. Criminality is also common, every sixth or seventh father having a police record. About every fourth child born in this suburb will grow up in a home where either the father or the mother is known for an addiction and/or criminality, and/or has been treated for mental illness. To conjure up and describe the atmosphere in a home in this suburb is not easy but in the present study information was obtained supporting the suspicion that many homes are characterised by insecurity, isolation and hopelessness and a serious unsatisfied need for help. Many of the mothers have grown up in rather special social conditions--for instance, in "broken homes", or with an alcoholic father or a mentally ill mother. As a result, nearly every tenth mother had been placed outside the home at an early age (in a foster-home or suchlike). In later years also, many of the mothers have had the burden of sick, malformed or mentally retarded children in their home, or have experienced the serious illness or death of some person close to them. Particularly in the period before their child's birth many women have had reason to feel anxious. About one woman in three has already had a miscarriage and/or abortion, and during pregnancy she may have suffered from serious nausea or depression. Quite a few also needed to take medicines during that time. In many families, it is reported, the man and woman have had trouble in living together, with resultant divorce situations, quarrels and assaults.(ABSTRACT TRUNCATED AT 400 WORDS)
