A case of Wernicke's encephalopathy with ataxia, confusion, memory loss, partial seizures of complex behavior and hypothermia, subsequent to thiamine depletion due to chronic malnourishment and triggered by an episode of acute vomiting and diarrhea, is reported, Computerized tomography (CT-scan) depicted small bilateral lesions in areas adjacent to the walls of the third ventricle, common location of the lesions seen in autopsy material of Wernicke's encephalopathy. Early diagnosis and treatment with vitamin B complex supplemented with intensive mnemonic and cognitive therapy led to complete recovery in a ten day period.

Kwashiorkor, with typical edema and skin rash is occasionally seen in affluent countries as a result of severe protein restriction. Treatment is with a lactose-free formula after rehydration and sometimes after a period of parenteral alimentation. Complications of therapy included: diarrhea, congestive heart failure, infections, a bleeding tendency, and seizures. Two of the 14 children in this series died.

PALA was given iv on a weekly schedule to 32 patients with advanced malignant tumors. A course of treatment consisted of three weekly doses. Patients were treated at eight dose levels, ranging from 900 to 6750 mg/m2. Gastrointestinal toxicity (diarrhea) and skin rash were dose-limiting. No consistent myelosuppression occurred, and no renal or hepatic toxicity was observed. Two patients who did not have metastatic intracranial disease experienced episodes of encephalopathy and seizures. No major therapeutic responses were observed during this phase I trial; however minor responses (greater than or equal to 25% tumor decrease) occurred in three patients (one with adenocarcinoma of the lung and two with epidermoid carcinoma of the bladder). Doses of 4500 mg/m2/week for patients with a performance status greater than or equal to 70 and 3750 mg/m2/week for patients with a lower performance status are recommended for phase II studies.

Septic encephalopathy is an early manifestation of sepsis. Changes in consciousness, focal or generalized seizures, multifocal myoclonus and/or varying hemiparesis are common clinical findings. All of these symptoms are reversible when sepsis has been successfully treated. Because there are no generally accepted criteria for the diagnosis of septic encephalopathy, it is a diagnosis of exclusion. We report the case of a 68-year-old patient who developed septic encephalopathy secondary to diarrhea and E. coli sepsis. In this case, symptoms of septic encephalopathy were fully reversed after the patient's E. coli sepsis had been adequately treated.

During a 2-year prospective study of children hospitalized with gastroenteritis, shigellosis was detected in 66 cases (9 per cent of 726 admissions). The age group for peak shigella incidence was 1-4 years. The incidence increased from 8 per cent in 1991, to 11 per cent in 1992. Shigella flexneri was the most common isolate (65 per cent), followed by Shigella sonnei (17 per cent), Shigella boydi (11 per cent), and Shigella dysenteriae (7 per cent). At presentation, 44 per cent had watery diarrhoea, followed by dysentery during hospitalization in the majority of cases. Seizures occurred in 27 per cent of cases and preceded diarrhoea in 15 per cent. Most Shigella flexneri and dysenteriae strains were resistant to co-trimoxazole, ampicillin, tetracyclin, and chloramphenicol. Nalidixic acid, gentamicin and cefotaxime were the most effective antibacterial agents. Case fatality was 3 per cent associated with strains resistant to the antibiotics used initially in the treatment.

Sulfites are usually added to food, beverages and pharmaceuticals as preservative antioxidants, bleaching agents, and dough conditioning agents. Ingestion of foods containing sulfites can cause abdominal pain, diarrhoea, seizures and death. Sulfite can react with cellular components and can cause toxicity. Changes in mucosal disaccharidases and phosphatase alkaline after sodium metabisulfite administration were investigated in the small intestine of rats. Female Wistar rats were given a diet supplemented with 0.25 or 2.5% sodium metabisulfite for 5 weeks. Sucrase, maltase, lactase and alkaline phosphatase were assayed in intestinal homogenates and in brush border membrane fractions. The intake of only 2.5% sulfite induced an increase in the specific activities of sucrase, maltase, and alkaline phosphatase compared to control levels (P < 0.05). Lactase levels were affected in a variable manner. The origin of such altered enzyme activities is still unknown.

This study was conducted to determine whether Depakene could be substituted for Depakote, which would represent a significant financial savings, without sacrificing symptom control or drug tolerance. Over an 8-week period of intensive monitoring, we changed 77 patients from Depakote to Depakene. Results showed no change in seizure control, no adverse upper gastrointestinal side effect, no weight change, no sleep disturbance, no change in aberrant behavior, and no change in appetite. Patients were less less lethargic on Depakene than on Depakote. However, there was some increase in diarrhea, of uncertain cause. Some changes in psychiatric symptoms were also noted. Overall, this drug change was well-tolerated.

Major depression is a common and disabling disorder with far-reaching social and economic implications. Nonetheless, major depression is treatable by one of the many currently available antidepressants with response rates of approximately 65-70%. Treatment of depression has improved in recent years because of the availability of effective and well-tolerated antidepressants, such as the selective serotonin reuptake inhibitors (SSRIs). The currently available antidepressants are generally equally effective and are distinguished primarily by side-effect profiles. The side effects of tricyclic antidepressants (TCAs) are attributed to their nonspecific interaction with cholinergic, histaminergic, serotonergic, and dopaminergic receptors in the central nervous system. The secondary amine TCAs, nortriptyline and desipramine, are preferred among the TCAs because of a more favorable side-effect profile. The TCAs are cardiotoxic, and overdoses are frequently fatal. Adverse effects, including potentially fatal drug and food interactions, limit the use of the monoamine oxidase inhibitors (MAOIs); however, these agents have a role in the treatment of depression with comorbid anxiety, refractory depression, atypical depression, and bulimia. The SSRIs possess a class side-effect profile of headache, nausea, and sexual dysfunction. Individual differences in side effects may distinguish fluoxetine (nervousness, restlessness), sertraline (diarrhea, loose stools), and paroxetine (dry mouth). The SSRIs all inhibit certain cytochrome P450 isoenzymes involved in the metabolism of drugs, such as the TCAs, and each SSRI has been reported to increase plasma concentrations of concomitantly administered TCAs. Bupropion therapy is associated with a risk of seizure development, which can be minimized by multiple daily doses. Trazodone is sedating and can rarely cause priapism. The related compound, nefazodone, does not cause sexual dysfunction or priapism, but is associated with sedation. Venlafaxine, a recently available antidepressant that appears to have efficacy in treatment-refractory depression, may cause nausea that requires gradual upward dosage titration. Higher doses of venlafaxine may also cause elevations in blood pressure, heart rate, and serum cholesterol. As more is learned about the pathophysiology of depression, even more specific and well-tolerated antidepressants will be developed.

During normal pregnancy, serum transaminase levels remain within normal limits. An elevated level observed in a pregnant woman always signals a disease process, most often of hepatic origin, but in certain cases, of muscular origin. During the last three months of pregnancy and in the immediate post partum period a large number of liver diseases can cause elevated transaminase levels, depending upon the clinical presentation. In everyday practice, a complete liver battery together with specialized consultation is required for all pregnant women with raised transaminase levels. Toxaemia gravis may be evident in patients with severely raised blood pressure, especially if seizures occur. Epigastric or subcostal pain should suggest hepatic involvement. Hypertension may however be absent and epigastric or left shoulder pain may be the only clinical signs. Acute liver steatosis is 20 to 50 times more rare than toxaemia and may cause nausea and vomiting. Certain non-specific signs such as asthenia, anorexia, polyalgia, abdominal pain, diarrhoea and fever, together with pruritus should suggest acute hepatitis. A 25-fold increase in transaminase level is commonly encountered. The risk of fulminating hepatitis is less than 1/1000 but should always be entertained. All drugs should be stopped and careful research for recent xenobiotic contamination (drugs, infusions, alphamethyldopa, etc.) should be undertaken. Viral hepatitis requires serovaccination of the newborn at birth. Herpetic hepatitis is rare but requires rapid diagnosis (liver biopsy) and treatment with acyclovir in addition to cesarean section and treatment of the newborn at birth. Rare cases of hepatitis E may occur after a stay in North Africa, the Middle-East, Southeast Asia or Mexico. Chronic cases with or without temporary pruritus suggest infectious hepatitis B or C although, in chronic hepatitis C, serum transaminase levels often return to normal during pregnancy. Rare cases of asymptomatic elevations of serum transaminase levels can reveal subclinical chronic hepatitis.

In a phase I trial, 17 patients were treated with 5-fluorouracil (5-FU) 500 mg/m2 and leucovorin (LV) 500 mg/m2 intravenously weekly for 6 weeks followed by 2 weeks' rest and interferon alfa-2b 1, 3, 5, 8, or 10 million units (MU) subcutaneously tiw with no rest period. The most common toxicities were fatigue (12), diarrhea (10), nausea/vomiting (7), and fever (7). The maximum tolerated interferon dose was 8 MU tiw. Fatigue and increased incidence of other toxicities rather than a single dose-limiting toxicity occurred at the next highest interferon level. ECOG grade III/IV toxicity occurred in 5 patients and included transient supraventricular tachycardia and brief seizure episode (1), dyspnea (1), decreased performance status (1), anemia requiring transfusion (1), and deep vein thrombosis (1). No toxic deaths occurred. Two patients with non-small cell lung cancer (NSCLC) had partial responses lasting 5 and 4 months. Two other patients with NSCLC had either minor response or stable disease, and 1 patient with colon cancer had a significant decline in serum CEA. The recommended alpha interferon dose is 8 MU tiw when given with this schedule of 5-FU/LV.
