Tick-borne encephalitis is transmitted by the tick ixodes ricinus. After the second world war an increase in the number of cases of encephalitis was observed and the neurotropic virus was isolated for the first time in 1948. Reservoir animals are mouse-like wild animals and also agricultural domestic animals. The infection is transmitted to humans through tick bites. It becomes apparent subjectively in headaches, vomiting, tiredness, giddiness and insomnia, and objectively in meningeal symptoms, extrapyramidal tremor, cerebellar ataxia, vestibular nystagmus and paresis. The treatment consists of strict rest in bed for 10 days at least and symptomatic support of the general health. Good results are obtained with antiedematous therapy with hydrocortisone or pyritinol.

A case report of mesenteric venous thrombosis with small bowel infarction in a 38-year-old woman who had been taking oral contraceptives is reported. The patient was admitted complaining of severe abdominal pain and vomiting for 36 hours. On admission, temperature was 37.5 degrees C and pulse 120/minute. Abdominal rigidity and left-sided abdominal tenderness were present. X-ray of the abdomen showed 2 distended loops of small bowel and 3 fluid levels. Serum amylase was normal. White cell count was 10,000/cu mm. There was a history of abdominal pain and diarrhea over a period of several years. For 6 months she had been taking Ovulen (mestranol .1 mg and ethynodiol diacetate .5 mg) for menstrual irregularity. 2 weeks earlier she had suffered an influenzalike illness with pleuristic chest pain, loin pain, urinary frequency, and dysuria. Chest X-ray and intravenous pylography were then reported as normal. At immediate operation, a 15 cm segment of ileum was found to be infarcted. Semipurulent fluid was present in the abdomen and areas of fibrinous peritonitis were observed. The involved segment of ileum was resected. A small thrombus was extracted from a mesenteric vein. Initial postoperative course was good but 3 days after operation chest pain, dyspnea, and giddiness developed and cardiac arrest followed. Resuscitation was successful. Pulmonary angiography then showed thrombi in all branches of the pulmonary artery. After heparin therapy symptoms improved and the patient left the hospital in 2 weeks, her condition being stabilized with warfarin and dipyridamole (Persantin). The diagnosis was confirmed by histological examination. Early recanalization of a mesenteric vein was noted. Other reported cases have shown an average prodromal phase of 4 or 5 days. The long-term diarrhea was considered as not connected with the present illness but the presumed influenza illness 2 weeks earlier may have been due to a pulmonary embolism. Of reported cases, 5 of 13 have died. Early diagnosis, prompt surgery, and heparin therpay are considered important.

Eighty-two patients were hospitalized following an accidental exposure to chlorine. All patients presented with dyspnoea and cough. The other symptoms included irritation of throat (53.6%), irritation of eyes (42.3%), headache (29.2%), abdominal pain (26.8%), vomiting (24.3%) and giddiness (9.7%). All of them had bronchospasm and 5 (6%) had cyanosis at the onset. An x-ray of the chest revealed patchy infiltrates in 3 (3.85%) and hilar congestion in 2 (2.44%). Pulmonary function tests showed an obstructive pattern in 27.4%, restrictive in 3.25% and mixed in 53.2%. Pulmonary functions were normal in 16.1% of the patients. Bronchoscopy revealed tracheobronchial mucosal congestion in all cases, hemorrhagic spots in 35.7%, erosions and ulcers in 12.5%. All patients were treated with oxygen, aminophylline, hydrocortisone and antibiotics. Haematemesis (n = 1) and pulmonary oedema (n = 2) developed 12 hours after the admission. Two other patients developed pneumonia 48 hours later. All patients recovered satisfactorily. On follow-up 16 patients had no sequelae after one year. Pulmonary functions were normal in 5 patients after 3 years of follow-up.

We did a double blind, crossover, prospective study comparing bicarbonate and acetate containing solutions in haemodialysis. Thirty stable patients with end stage renal disease on maintenance haemodialysis while awaiting a renal transplant were each studied on three dialysis with acetate and three with bicarbonate. Nine patients developed symptoms like headache, nausea, vomiting, giddiness, and malaise and developed hypotension during acetate dialysis and three patients during bicarbonate dialysis. There were symptoms during 16.66% of acetate dialysis sessions and 5.55% of bicarbonate dialysis sessions. (P less than 0.05). There was a statistically significant decrease in PaO2 and PaCO2 on acetate dialysis at 30 minutes after initiation of dialysis. There was no significant difference in weight loss on dialysis, or in blood pressure and correction of acidosis. We conclude that bicarbonate dialysis is better tolerated, but acetate intolerance is not a major problem since we use small surface area dialysers (0.8 M2).

An outbreak of food poisoning resulting in 13 deaths in children occurred in Malaysia during the Chinese Festival of the Nine-Emperor Gods in 1988. The offending food was a Chinese noodle called 'Loh See Fun' (LSF). The source was traced to a factory where a banned food preservative was added to make the LSF. The food poisoning was attributable to aflatoxins and boric acid. The clinical features included vomiting, pyrexia, diarrhoea, abdominal pain, anorexia, giddiness, seizures, and eventual coma. Initially, many presented with a Reye-like syndrome. Eleven post-mortem examinations were performed. The pathological findings included extensive coagulative necrosis of the liver with proliferative 'ductal/ductular metaplasia of the hepatocytes'. Giant cell formation, central vein sclerosis, bile stasis, and steatosis were also noted. There was presence of acute tubular necrosis, superficial upper gastrointestinal erosions, and ensuing encephalopathy. The eventual cause of death is acute hepatic and renal failure.

The authors' findings permit a conclusion that the risk of ethmozine overdosage leading to undesirable side effects (dryness in the mouth, noise in the ears, a 'net' in eyes; giddiness, nausea, vomiting) is very high when routine ethmozine doses are administered to patients with grave (Stages II-III) impairments of liver function; this is explained by (1) reduced rate of ethmozine biotransformation, this resulting in a heightened concentration of the drug in the blood, and (2) by an increase of the drug free fraction concentration due to its reduced ability to bind with the blood plasma proteins. This necessitates a pharmacokinetic monitoring of such patients prescribed ethmozine and a correction of the drug dose, if necessary.

Simple cardiopulmonary functions were studied serially in 26 mountaineers between sea level and an altitude of 25,200 ft. Up to 12,000 ft there was no altitude sickness, though there were complaints of leech bite (26.9%) and blisters (3.8%). One member died of exhaustion, two developed pulmonary oedema, one "flu" (at 15,600 ft) and one pleural rub (at 21,000 ft). Up to 16,000 ft altitude, 4 to 7.7% developed diarrhoea or epistaxis only, but at higher levels 25 to 50% subjects developed several symptoms, besides excessive dyspnea. These included diarrhoea (35-60%), vomiting (30%) abdominal pain (35-60%), rectal bleeding (15%), chest pain (10-40%), dry cough (40-60%), giddiness (30%) and poor memory (7.7%). A small rise in blood pressure was seen (for systolic at lower and diastolic at greater altitudes). After 18,200 ft the steady increase seen in VE slowed and the rise in heart rate and respiratory rate (f) became steeper. After a small rise at 7,800 ft, FVC and FEV1 showed a gradual decline at higher altitudes. After a large initial increase in PEFR up to 12,000 ft, a gradual decline was seen. The mean weight loss during the expedition was 8 +/- 2.7 kg. These changes seem to be due to an incomplete acclimatisation, which future mountaineering teams should take into consideration to avoid health problems and improve performance.

Primidone was compared to the unselective beta adrenoceptor antagonist propranolol in the suppression of essential tremor. In a 4-week single-blind placebo-controlled study primidone was given in increasing doses from 62.5 mg X 1 up to 250 mg X 3 daily and propranolol 20 mg X 3 daily. The drugs produced a similar reduction in the degree of tremor after 2 and 1 weeks' medication respectively. This indicates that primidone can be an alternative to propranolol when beta-blockers are contraindicated. However, primidone was significantly even more effective in the beginning after only 2 doses, when at the same time 10 of 13 patients showed a maximum of acute toxic side-effects producing nausea, vomiting, giddiness and/or sedation. Correlation analysis between the individual tremor amplitude reductions and plasma primidone concentrations showed on the second day a tendency towards a greater reduction in tremor in those patients with the highest primidone plasma concentration. By the fourteenth day tremor had increased compared with the second day and correlation analysis between individual increase in tremor amplitude and plasma phenobarbital concentrations showed the highest degree of tremor increase in those patients who had the highest levels of phenobarbital. These and other data suggest that after the first doses, tremor suppression and acute toxicity is related to the initial exposure to primidone and the plasma level of the drug itself rather than its metabolites phenobarbital and phenylethylmalanomide. The individual tremor frequency spectrums did not change significantly during the placebo and propranolol periods, whereas the frequency tended to decrease during the primidone period.

In a field study conducted in Burma, 54 semi-immune adults suffering from falciparum malaria (mean parasite count, 15 328/mm(3) before treatment) were given a single dose of a fixed combination of 750 mg mefloquine base, 1500 mg sulfadoxine, and 75 mg pyrimethamine (3 tablets of Fansimef). All these patients were cleared of asexual parasites by day 7, giving a cure rate of 100%; the mean clearance time was 2.6 days. Reappearance of parasitaemia occurred in 10 patients on or before day 7 and persisted for one day in 8 of them and for two days in 2 patients. It eventually disappeared without further treatment. No recrudescence occurred during the follow-up time of four weeks despite the fact that there was active transmission of Plasmodium falciparum in the area throughout the whole of the study period. The drug was generally well tolerated, though mild to moderate giddiness was reported by 49 patients (90.7%) and severe giddiness by 3 patients (5.5%). Nausea occurred in 25 patients (46.3%) and vomiting in 17 (31.5%).

In a double-blind placebo-controlled cross-over study the encephalotropic and psychotropic properties of sertraline--a new potent and highly selective inhibitor of synaptosomal serotonin uptake--were studied along with blood levels of the parent drug and main metabolite in ten normal healthy volunteers. They received randomized at weekly intervals oral single doses of placebo, 100, 200 and 400 mg setraline and 100 mg zimelidine as reference drug. Blood sampling, EEG recordings, psychometric tests and evaluation of pulse, blood pressure and side-effects were carried out at the hours 0, 2, 4, 6, and 8. Blood level investigations demonstrated that sertraline is slowly absorbed with dose-dependent blood concentrations peaking in the 4th to 6th hour and remaining high thereafter, while the main metabolite, CP-53261 exhibited an even slower rise in plasma concentration up to the 8th hour. Computer-assisted spectral analysis of the EEG demonstrated slight effects of 100 mg zimelidine and 100 mg sertraline on human brain function, but moderate to marked effects after 200 and 400 mg sertraline as compared with placebo. Changes after 100 mg sertraline and the reference compound resembled the pharmaco-EEG profiles of antidepressants of the desipramine type and were indicative of some vigilance-improving properties while higher doses of sertraline induced alterations reminiscent of those after antidepressants of the imipramine type, thereby reflecting vigilance changes of the dissociative type. This neurophysiological conclusion was supported by the psychometric and psychophysiological data showing partly after 100 mg sertraline and zimelidine an improvement in psychometric performance, while 200 and 400 mg sertraline induced a deterioration of noopsyche and thymopsyche of the normal volunteers. Psychophysiological variables exhibited a dose-dependent change in CNS activation and a widening of the pupillary size. Time-efficacy calculations based on pharmacodynamic changes demonstrated maximal encephalotropic effects after 100 mg zimelidine in the 2nd to 4th hour, and after setraline in the 4th to the 6th hour, which is in agreement with the blood level data. Pulse, systolic and diastolic blood pressure showed no clinically relevant findings. Side-effects were non-existent to minimal after 100 mg zimelidine and sertraline, but marked after 200 and 400 mg sertraline characterized by nausea, vomiting, diarrhea, giddiness, restlessness, tremor and trismus.
