The results of a double blind trial of Viloxazine and Desipramine in 30 hospitalized depressives are reported. Hamilton's Rating Scale for Depression was the outcome criterion. No statistically significant differences were found between drugs in efficacy and onset of action. Patients on either drug showed a significant reduction in symptoms after one week of treatment and at the end of the trial. Side effects reported with Viloxazine were predominantly nausea and dizziness of a transient nature. Patients on Desipramine reported the usual side effects associated with antidepressant use and two of them had to be withdrawn from the trial because of an allergic rash. Laboratory values and EKG tracings did not show any trend of abnormalities. It is concluded that Viloxazine is an effective and safe antidepressive drug and seems to be particularly indicated in geriatric and cardiovascular patients with a concomitant depression.

Thirty-eight obese patients, resistant to conventional diet therapy, agreed to consume a 1.09 MJ (260 kcal)/day semi-synthetic diet consisting of 25 g egg albumin, 40 g oligosaccharides, vitamins and minerals, and were seen weekly as outpatients for eight weeks. At the beginning, the semi-synthetic diet was given with either the anorectic drug, mazindol (2 mg/day) or a placebo for four weeks and then changed over for the remaining four weeks; the study being conducted on a double-blind basis. The final treatment was a 4.2 MJ (1000 KCAL) conventional diet for a further four weeks without drug or placebo. Twenty-five patients completed the first eight weeks and 21 patients the final four weeks of the trial. The total mean weight losses were as follows: week 4, 9.3 kg; week 8, 13.7 kg; week 12, 12.2 kg. There was no significant difference in weight loss between mazindol treatment and placebo but the former group reported feeling less hungry. The chief side-effects observed were dizziness, nausea, dry mouth, insomnia and depression which were more frequent with mazindol. Six patients had to stop mazindol because of side-effects, but were able to continue the diet alone. It is concluded that a semi-synthetic diet containing 1.09 MJ (260 kcal) daily can be successfully employed in the treatment of obese outpatients, and is a practical therapeutic alternative to admission to hospital. There is no clinical advantage to be gained by the additional use of the anorectic drug, mazindol.

The efficacy and safety of maprotiline (Ludiomil) was compared to imipramine in patients with manic-depressive illness, depressed type (DSM II 296.2). Three hundred forty-one patients from 16 different centers entered this four-week double-blind controlled trial, with 171 in the maprotiline and 170 in the imipramine group. Efficacy measurements included the Hamilton Depression Scale, the Self-Rating Depression Scale, and the Investigator's Overall Assessment of Effectiveness. Tolerability was monitored by collection of treatment-emergent signs and symptoms (TESS), blood pressure and pulse measurements, EKGs, and EEGs. Dosage was fixed for the first week at 50 mg t.i.d. and thereafter could be varied between 50 and 300 mg daily. Clinically and statistically significant reductions in symptomatology were noted in both drug groups for most efficacy parameters at each visit during therapy. Comparison between the drug groups revealed no difference in terms of the scales utilized. A trend toward fewer TESS in the maprotiline group was noted, especially for the side effects nausea, nervousness, and increased sweating.

A large number of reports have been devoted to the physiologic and toxic effects of methyl chloride, many of which are based on case histories involving occupational exposure. The detrimental actions of methyl chloride on the central and peripheral nervous systems are well established effects. It is a moderately severe narcotic and potentially severe nerve poison. Chronic intoxication is associated with damage to the central nervous system (CNS), kidneys, liver, bone marrow, cardiovascular system, respiratory system, and intestinal tract. The signs and symptoms range from the more severe medical dysfunctions such as cardiac irregularities, respiratory paralysis, nerve degeneration, and severe convulsions to the more subtle clinical observations such as CNS depression, nervousness and emotional instability, insomnia and anorexia, ataxia, blurred vision, light-headedness, nausea, dizziness, narcosis, and disorientation. The behavioral correlates of these and other neurotoxic effects of methyl chloride suggest that a gradual behavioral degradation occurs. Pharmacodynamic studies have shown the compound to be rapidly absorbed by the blood with most authors attributing the toxicity to an enzyme-catalyzed methylation reaction in the body. Despite the fact that several investigators have attempted to correlate such biological responses of methyl chloride with its toxicity, the present knowledge of the problem still lacks a detailed mechanism of action. Until such mechanisms are verified, adequate methods to assess subclinical neurological and behavioral changes must be effectively developed.

Trichloroethylene (TCE) has been an industrial chemical of some importance for the past 50 years. First synthesized by Fischer in 1864, TCE has enjoyed considerable industrial usage as a degreaser and limited medical use as an inhalation anesthetic and analgesic. This TCE overview provides a narrative survey of the reference literature. Highlights include history, nomenclature, physical and chemical properties, manufacture, analysis, uses, metabolism, toxicology, carcinogenic potential, exposure routes, recommended standards, and conclusions. Chemically, TCE is a colorless, highly volatile liquid of molecular formula C2HCl3. Autoxidation of the unstable compound yields acidic products. Stabilizers are added to retard decomposition. TCE's multitude of industrial uses center around its highly effective fat-solvent properties. Metabolically, TCE is transformed in the liver to trichloroacetic acid, trichloroethanol, and trichloroethanol glucuronide; these breakdown products are excreted through the kidneys. Most toxic responses occur as a result of industrial exposures. TCE affects principally the central nervous system (CNS). Short exposures result in subjective symptoms such as headache, nausea, and incoordination. Longer exposures may result in CNS depression, hepatorenal failure, and increased cardiac output. Cases of sudden death following TCE exposure are generally attributed to ventricular fibrillation. Current interest in TCE has focused on recent experimental data that implicate TCE as a cause of hepatocellular carcinoma in mice. No epidemiological data are available that demonstrate a similar action in humans. The overall population may be exposed to TCE through household cleaning fluids, decaffeinated coffee, and some spice extracts. The NIOSH recommended standard for TCE is 100 ppm as a time-weighted average for an 8-hr day, with a maximum allowable peak concentration of 150 ppm for 10 min.

Food intake, appetite and a variety of feelings were measured pre- and post-operatively in obese patients undergoing jejuno-ileal bypass surgery. Decreased food intake correlated closely with the amount of weight loss at both 4 and 30 months after surgery. Malabsorption correlated with weight loss at 4 months but not 30 months post-operatively. The cause of the decreased food intake is unknown and cannot be completely explained by either depression, nausea, malabsorption, liver disease, an attempt to avert diarrhoea, or decreased appetite.

Acute dapsone poisoning is rare and such cases are either accidental or suicidal. Though accidental DDS poisoning are reported in children, the same is fairly uncommon in adults. Only 2 such cases are reported in India literature. We here report 4 cases of fatal sucidial DDS poisoning in adults resulting death in 3 cases. The reported acute symptoms include nausea, vomiting, hyperexcitability followed by depression, Carpopedal spasm or convulsions. The most marked signs are dyspnoea and cyanosis. The symptoms are due to methaemoglobinaemia, and or sulphaemoglobinaemia. Normally dapsone induces red cell haemolysis and even with small therapeutic doses of 25-100 mg per day, and in toxic doses reduces the oxygen carrying capacity of blood and damages the red cells making them more vulnerable for haemolysis. The peculiarity of the presentation in this series are manifestation of severe haemorrhagic episode in one case and progressive jaundice in another besides cyanosis. None of the cases had carpopedal spasm or convulsion. Out of four cases three died inspite of intensive care, intravenous vitamin C, exchange transfusion (2 cases) and other supportive measures. Intravenous methylene blue could not be used in these cases due to non-availability.

The effects of 2 doses of nefopam, d-amphetamine, pentazocine, and placebo were studied in healthy male sleep-deprived volunteers to determine whether the drugs improved or impaired coordination and whether they induced subjective effects. A critical tracking task was used to study hand-eye coordination. D-amphetamine, 10 mg orally, significantly improved tracking performance and made subjects feel better able to perform tasks but more anxious. It also made them feel more alert, steady, sociable, and strong. Pentazocine, 45 mg intramuscularly, caused deterioration in tracking performance and was followed by reports of depression, gloominess, dreaminess, nausea, and injection site pain. There was no significant change in tracking performance or subjective effects after both doses of nefopam and placebo.

This study comprises 81 thyrotoxic patients with onset after the age of 60. In elderly persons, toxic multinodular goiter is the most common cause (68%) of hyperthyroidism, followed by solitary thyroid nodules (16%) and Graves' disease (16%). Cardiovascular disorders (cardiac failure, arrythmias etc.) constitute the first and often the only symptom in 62% of the cases. The other forms of appearance are both various and deceptive: depression, slight fever, asthenia or nausea. Separate analysis of the three forms of hyperthyroidism did not reveal clinical, biological or therapeutic differences between them, except an inferior rate of captation for the toxic nodules. Isolated measurement of T3 or T4 is often insufficient to confirm the diagnosis because either of these hormones may appear at a normal rate. In three cases only the free thyroxin index was pathological on first determination. The authors have established that the autonomous nodules are larger and more active after, rather than before, 60 years of age, and have attempted to define their morphological identity. The results of the treatment are analyzed and preference is expressed for radioactive iodine in every form of hyperthyroidism.

23 patients whose weight varied from ninety-eight to 220 kilos were subjected to four different types of jejuno-ileal by pass operations: terminal-lateral (14 X 4) in three, terminal-terminal (14 X 4) in fifteen, (12 X 8) in two, and (10 X 8) in three. The defunctionalized intestine was anastomized to the transverse colon. Liver, jejenum and ileal biopsies as well as profilactic apendectomy were performed in all the cases along with colecistectomy when possible. All our patients were carefully studied in the pre and postoperative periods. The postoperative follow-up varied from 16 to 72 months, during which time a short and long-term mortality of 8.6% was observed. In eight patients it was necessary to reestablish normal intestinal transit for one or two reasons: rapid weight loss or total lack of patient cooperation. During the first few months post-op, diarrhea, nausea, vomiting, loss of apetite, weakness, inactivity, depression, electrolyte anormalities, anemia and increased hepatic esteatosis were the clinical and pathological findings most frequently encountered. With the cooperation of the patient it is possible to correct all these alterations: it is for this reason that the importance of right patient selection is emphasized. The rate of post-operative weight loss varied from patient to patient with an ideal weight being achieved between 18 and 24 months after the operation. Only in those patients reoperated upon to establish normal intestinal transit was the lost weight recuperated. Along with rigid patient selection, the success of this operation depends upon interspecialty teamwork during the preoperative evaluation as well as the follow up period in order to resolve the intricate physio-pathological problems that so frequently arise.
