Twenty seven patients, inspected by endoscope, and diagnosed as having the Mallory-Weiss syndrome, have been studied taking into account their age, sex, background, clinic presentation, manifestations, number of lacerations, associated lesions and evolution. Twenty three of them were males and 4 females. The age average was 46.7 years. Only 8 patients had intra-abdominal increased pressure, suffering retching and vomiting 7 of them, while one had a cough access. Out of the 21 patients that we controlled, 9 were chronic alcoholism while 3 had ethanol intoxication previously. Immediate prior ingestion of salicylates had taken place in 6 patients. The clinical presentation of 22 of them was gastrointestinal bleeding, that is, 4.9% of all the upper endoscopies carried out within the bleeding patients. Single laceration was present in 22 cases, double one in 4, and triple in 1. We have frequently found endoscopy lesions associated, the most common one (37%), was hiatal hernia. They all were medically treated except one, who was operated because of gastric perforation was associated. Just one of the Mallory-Weiss syndrome patient died, due to an associated diffused bleeding gastritis.

During a 19-year period ending December 1978, we treated 40 patients with upper gastrointestinal bleeding secondary to the Mallory-Weiss syndrome. Thirty patients had the triad of vomiting, hematemesis and alcoholism. The presence of lacerations within the gastric cardia was associated with the presence of hiatal hernia (p = 0.03). Endoscopic examinations demonstrated 32 of 38 additional upper gastrointestinal lesions associated with the syndrome that could have been mistaken as the actual source of hemorrhage. During the second decade, as compared with the first decade, widespread use of fiberoptic esophagogastroscopy led to the identification of the bleeding lacerations in 71% of the patients (versus 47% in the first decade) and in 80% (versus 0% in the first decade) of the patients who required an operation to control the bleeding. Although there was a 7.5% mortality rate in the two decades, the incidence of operative treatment tended to decrease (42-24%; p = 0.13). More impressive were the decreases in transfusions (14 units to 5 units per patient) and in delays before surgery (38 hours to 17 hours) (p equal to 0.05). Improved endoscopic diagnosis facilitates prompt and economic treatment.

Magnesium (Mg) deficiency occurs frequently in chronic alcoholism and may contribute to the increased incidence of osteoporosis and cardiovascular disease seen in this population. Mg deficiency is primarily due to renal Mg-wasting and is exacerbated by dietary Mg deprivation, gastrointestinal losses with diarrhea or vomiting, as well as concomitant use of drugs such as diuretics and aminoglycosides. Osteoporosis is prevalent in the alcoholic population. Mg deficiency may contribute to increased bone loss by its effects on mineral homeostasis. In Mg depletion, there is often hypocalcemia due to impaired parathyroid hormone (PTH) secretion, as well as renal and skeletal resistance to PTH action. Serum concentrations of 1,25-vitamin D are also low. These changes are seen with even mild degrees of Mg deficiency and may contribute to the metabolic bone disease seen in chronic alcoholics. Hypomagnesemia in alcoholics may also contribute to increased cardiovascular disease by altering platelet function. Mg deficiency has been demonstrated to enhance platelet reactivity. In these studies, Mg was shown to inhibit platelet aggregation against various aggregation agents. Patients with Mg deficiency were shown to have increased platelet aggregation that was normalized with Mg therapy. The antiplatelet effect of Mg may be related to the finding that Mg inhibits the synthesis of thromboxane A2 and 12-hydroxyeicosatetraenoic acid, eicosanoids thought to be involved in platelet aggregation. Mg also inhibits the thrombin-induced Ca2+ influx in platelets, as well as stimulates synthesis of prostaglandin I2, the potent antiaggregatory eicosanoid. Therefore, Mg deficiency may increase platelet aggregation and cause increased hypertension and atherosclerotic cardiovascular disease in alcoholics.

Sulfiram, a drug applied topically to treat scabies, produces effects similar to those of disulfiram after subsequent ingestion of ethanol. Disulfiram, used in aversion therapy in the treatment of alcoholism, inhibits hepatic aldehyde dehydrogenase (ALDH) causing an accumulation of acetaldehyde after ethanol ingestion. The increased tissue levels of acetaldehyde cause a spectrum of undesirable side-effects including flushing, nausea, vomiting, and tachycardia, which are referred to as the disulfiram reaction. Previous studies have shown that in vitro sulfiram is a very weak inhibitor of ALDH, but solutions of sulfiram markedly increase in potency with time. In the present study, fresh solutions of sulfiram were exposed to fluorescent room light under ambient conditions and analyzed at timed intervals by HPLC. At least eight products, including disulfiram, were formed in the light-exposed sulfiram solutions, but not in solutions kept in the dark. Structural characterization of two of the photolysis products was obtained by on-line microbore HPLC-mass spectrometry (mu LC-MS) and on-line microbore HPLC-tandem mass spectrometry (mu LC-MS/MS) using continuous flow-liquid secondary ion mass spectrometry (CF-LSIMS) as the primary ionization method. Sulfiram was converted to disulfiram at an initial rate of 0.7%/hr, and the formation of disulfiram correlated with the increase in ALDH inhibition in vitro. The results of this investigation show that while sulfiram is a weak inhibitor of ALDH in vitro, it is readily photoconverted to disulfiram, a very potent inhibitor of ALDH, which may explain the adverse reaction to ethanol after sulfiram therapy.

Thirty-nine Danish cases of Capnocytophaga canimorsus septicemia were reviewed to determine the clinical course of this infection. The cases of septicemia were related to recent dog bites or other close contact with dogs. The period from the bite to the onset of symptoms ranged from 1 to 8 days. The mean age of the patients was 59.1 years (range, 28-83 years). Underlying conditions included previous splenectomy and alcoholism. Thirteen patients had previously been in good health. Common initial symptoms were fever, malaise, myalgia, vomiting, diarrhea, abdominal pain, dyspnea, confusion, headache and skin manifestations. Disseminated intravascular coagulation developed in 14 patients, meningitis in 5, and endocarditis in 1. Twelve of the patients died. All patients except two were treated with penicillin or ampicillin. Five patients had received antibiotics prior to admission. Attention should be drawn to C. canimorsus septicemia in cases of febrile illness following dog bites or contact with dogs, as well as those involving previously healthy persons. The incidence of this condition in Denmark is estimated to be 0.5 case per 1 million people per year.

The study group on Head Injury of the Italian Society for Neurosurgery suggests the following guidelines for minor head injured patients management. Patients either oriented to time, space and person (GCS 15) or confused (GCS 14) are included among the group of minor head injury. Criteria of exclusion are the presence of focal neurological deficits, open injury and a GCS < or = 13. Six categories of risk factors (coagulopathies, alcoholism, drug abuse, epilepsy, previous neurosurgical treatments and disabled elderly patients) relevant to the clinical course are identified. Three group of patients are distinguished. Patients in the Group 0 (GCS 15, without loss of consciousness, amnesia, diffuse headache, vomiting) could be sent home from Emergency Department after at least 6 hours period of observation with an information sheet. Patients in the Group 1 (GCS 15, with loss of consciousness and/or amnesia and/or diffuse headache and/or vomiting) require clinical observation (> or = 6 hours) and neuroradiological assessment. According to hospital availability, either skull-X rays or CT scan is obtained. In the presence of a skull fracture a CT scan is mandatory. In the presence of intracranial lesions, neurosurgical consultation is requested. In the absence of skull fractures or intracranial lesions the patient is admitted for observation (> or = 24 hours). Patients in the Group 0 and in the Group 1 with a risk factor (R) are admitted to the hospital (> or = 24 hours) and submitted to a CT scan. In patients with coagulopathies or in treatment with anticoagulants a CT scan should be repeated before discharge even in the absence of intracranial lesion on the first CT. In patients in the Group 2 (GCS 14) a CT scan is obtained in all cases independent of the presence of a risk factor.

Disulfiram is used in alcohol rehabilitation because it inhibits aldehyde dehydrogenase and consequently causes the disulfiram-ethanol reaction (vomiting, vertigo, anxiety, cardiovascular effects) after ingestion of alcoholic beverages. However, adverse effects on the central nervous system (for the most part psychotic reactions, acute organic brain syndrome, catatonia) may appear as a direct result of the drug itself. Disulfiram and its metabolite carbon disulfide inhibit dopamine beta-hydroxylase, increasing the levels of dopamine and reducing those of norepinephrine in the central nervous system. We observed direct disulfiram-induced toxicity on the central nervous system in 8 abstinent patients in whom a disulfiram-ethanol reaction had been excluded. Risk is increased when 1) excessive amounts of the drug are ingested; 2) the patient is already suffering from a major psychiatric illness; 3) the patient has anatomical brain lesions. In all cases observed, the toxic effects appeared in the first weeks and were reversed after suspension of the drug (except in one patient who died from severe bronchopulmonary infection). We thus suggest the following protocol: 1) physical examination and interview 3-4 weeks after initiation of treatment; 2) as a general rule, in abstinent patients, the lowest possible maintenance dosage should be administered. This strategy, despite the risk of underdosage, meets the goals inherent in an integrated medical and psychosocial approach to the treatment of alcoholism with which these patients seem better able to comply.

Postemetic spontaneous rupture of the esophagus is an intrathoracic disaster which is generally lethal if untreated. The tragedy seems to strike more often than commonly suspected. The current literature review focuses on publications since 1980 and includes the retrospective review of 18 additional patients treated in our hospital for spontaneous rupture of the esophagus. Frequently, a wide variety of unspecific symptoms has led to the mistaken diagnosis of an acute abdomen, pancreatitis or cardiac arrest. About 40% of the patients with spontaneous rupture of the esophagus presented a history of alcoholism or heavy drinking and 41% suffered from gastroduodenal ulcer disease. Pain (83%) and vomiting (79%) often associated with dyspnea (39%) and shock (32%) are the major symptoms. This unspecific symptomatology delayed the correct diagnosis of the Boerhaave's syndrome and resulted in a significant complication rate. The mortality rate associated with Boerhaave's syndrome was 50% from the first successful surgical repair in 1947 by Barrett to 1980. After 1980, however, the mortality rate dropped to 31%, because of earlier diagnosis, surgical repair and improvement in intensive care. When surgery is delayed, the prognosis of patients with spontaneous rupture of the esophagus is in general severe.

A 66-year-old man with a history of chronic alcoholism presented with Kussmaul respirations following several days of fasting accompanied by vomiting, in the presence of continued ethanol intake. He was subsequently found to have a serum glucose level of <20 mg/dL and an anion gap of 36. Despite his profound hypoglycemia, he was fully alert with no obvious neurological deficits. He recovered without incident with intravenous saline, dextrose, thiamine, and antibiotics for a bacteremic pneumonia. He had no evidence of hypoxemia, hypotension, or other features of sepsis. Alcoholic ketoacidosis in the setting of hypoglycemia is discussed. If the serum glucose level is less than the anion gap, the diagnosis of alcoholic ketoacidosis should be considered.

This study describes the medical practice among a sample of indigenous healers from Thaba Nchu, Ganyesa, Kurumane, Mankwe, and Molopo regions of the North West province of South Africa. Data were obtained from interviews conducted among 35 indigenous healers recommended by heads from a sample of 40 villages. Findings indicate that 60% were Botswanan. 51% were female. 85.7% were aged 30-59 years. 77% were married, and 5.7% were divorced. 31% had a lower primary education, and 25.7% finished high primary schooling. 22.4% had no formal schooling. 60% were bone throwers, and 34.2% were bone throwers and sangomas. 54% received their training "by their ancestors through dreams." 31% received formal training in indigenous healing. 14% served an apprenticeship with an experienced healer. 94% had a period of training from 2-5 years. 57% were registered with an association for indigenous healers. 77% relied on bone throwing for diagnosis of health problems. Other treatment methods included scarification, enema, induced vomiting, ritual performance, and prevention of witchcraft. Healers treated infertility, septic sores, impotence, sexually transmitted diseases, deliveries, makgome or boswagade, asthma, mental illness, high blood pressure, palpitations, tuberculosis, alcoholism, diabetes, and cancer. Pediatric diseases that were treated included tlhogwana, ditantanyane, measles, Kwashiorkor, and whooping cough. Healers relied on the following methods for disease prevention and health promotion: home fortifying, home cleansing, personal cleansing, scarification, and cultural education in taboos. 74% made referrals to either a western trained physician (17 out of 26) or other healers. All were generalists. Clients included professionals, such as nurses, teachers, and religious ministers. Although there is potential danger in some treatment methods, healers serve an important role in health prevention and treatment.
