80 strictly selected patients with chronic renal insufficiency with plasma creatinine values of 1.4--14.5 mg% were examined according to a fixed scheme to determine the presence of symptoms and signs of renal encephalopathy. The general cerebral symptoms complained of were headache in 33.4% of the patient material, dizziness in 30.3%, easy fatigability in 62.5%, giddiness in 18.8% and insomnia in 37.5%. The most prominent neurological findings were hyperactive deep reflexes in 30% and action tremor in 23.8%. The symptoms of organic brain syndrome were impairment of memory in 32.5%, weakness of concentration in 28.8% and lability of affect in 63.7%. Diffuse EEG abnormalities were found in 26.2%. While the clinical neuropsychiatric symptoms did not show any statistically significant correlation with the various internal medical data, a trend was observed in the greater number of pathological EEGs with an increase in the impairment of renal function. Furthermore, there was a statistically significant correlation, (alpha less than or equal to0.015) between the occurrence of pathological EEGs and the plasma creatinine and BUN values. It is remarkable that the patients with abnormal EEGs had a relatively low mean creatinine level of 5.89 mg%. The strict dietetic management of the patients is regarded as one of the deciding factors for the relatively low frequency of neuropsychiatric symptoms in the material studied.

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.

Takayasu arteritis is the commonest cause of renovascular hypertension in India. The clinical and radiological features, complications and course of 83 patients (51 females, 32 males) seen during the period from 1972-1990 are described in this study. The age of the patients ranged from 5 to 53 years with the mean +/- SD of 26.9 +/- 9.7. Hypertension (n = 50) and the related symptom of headache (n = 40), dyspnea (n = 24), and giddiness (n = 20) were common at presentation. Twelve patients were in congestive cardiac failure. The symptoms of activity with fever and arthralgia were present in only 16% contrary to reports from Japan and Mexico. Abnormal arterial pulses and bruit over abdominal (37%) or extra abdominal great arteries (25%) were useful clinical clues to suspect Takayasu arteritis. Rapid sequence intravenous urography was a sensitive screening procedure and predicted correctly the presence of renovascular disease in 80% of the patients. The diagnosis was confirmed on aortography in 72. In the rest, the clinical features and autopsy findings confirmed the same. The four patterns of the disease based on the anatomical extent of involvement were recognised. These were: type I (n = 8) with involvement of aortic arch and its branches, type II (n = 25) descending thoracic and abdominal aorta type III (n = 46) combination of I and II and type IV (n = 4) pulmonary artery in addition to any of the above.(ABSTRACT TRUNCATED AT 250 WORDS)

In a double-blind, placebo-controlled trial, human brain function and mental performance were studied under two different degrees of hypoxia after administration of two different doses (6 mg and 9 mg) of co-dergocrine mesylate (CDM) utilizing blood gas analysis, EEG mapping and psychometry. Hypoxic hypoxidosis (i.e. impairment of cerebral metabolism due to hypoxia) was experimentally induced by a fixed gas combination of 9.8% oxygen (O2) and 90.2% nitrogen (N2) (found in 6000 m altitude), and of 8.6% O2, 91.4% N2 (found in 7000 m altitude), which was inhaled for 23 min under normobaric conditions by 18 healthy volunteers. They received randomized after an adaptation session placebo, 6 mg and 9 mg co-dergocrine mesylate (CDM). Evaluation of blood gases, brain mapping and psychometry was carried out at 0, 2, 4, 6, 8 h after oral drug administration. Blood gas analysis demonstrated a drop in PO2 to 42 and 32 mm Hg 23 min after inhalation of the 9.8% and 8.6% gas mixture, respectively, PCO2 decreased to 32 and 31 mm Hg, pH increased to 7.46 and 7.47 and base excess increased to 0.50 and 0.90 nmol/l, respectively. EEG mapping demonstrated an increase in delta and decrease of alpha power and a slowing of the centroid over almost the whole brain. 6 mg and slightly less so 9 mg CDM attenuated this deterioration of vigilance (i.e. dynamic state of the neuronal network determining adaptive behavior). At the behavioral level, moderate hypoxia induced a deterioration of noopsychic performance, which was mitigated by 6 mg, but not by 9 mg CDM. A deepening of the hypoxia resulted in a loss of these brain protective effects of both doses. Decrement of the thymopsyche increased after both doses in the moderate hypoxic condition, while under marked hypoxia 6 mg CDM attenuated and 9 mg aggravated this deterioration. Time-wise, brain protective effects reached the level of statistical difference between the 2nd and the 6th hour. Somatic complaints like feeling dazed, giddiness and headache were mitigated dose dependently by CDM in the moderate, but not in the marked hypoxic hypoxidosis.

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).

In a multicenter, prospective study of step II antihypertensive therapy with indoramin, 1,847 hypertensive patients (773 men and 1,074 women) between the ages of 18 and 70 years were treated by 148 general practitioners. Patients whose blood pressure was inadequately controlled after 4 weeks of therapy with cyclopenthiazide (0.25 to 1.0 mg/day) had indoramin (25 to 200 mg/day) added to their treatment regimen. During cyclopenthiazide treatment, mean (+/- SD) blood pressure decreased from 176/105 +/- 20/7 mm Hg at baseline to 164/98 +/- 21/9 mm Hg (p less than 0.001), and only 447 (24%) patients obtained satisfactory blood pressure control. The addition of indoramin produced a further reduction in mean blood pressure from 169/102 +/- 18/6 to 152/89 +/- 18/8 mm Hg during the first 3 months of treatment (p less than 0.001); this response was maintained for up to 2 years. Satisfactory blood pressure reduction was achieved in 79% of the patients who received indoramin (mean dose, 68 mg/day) plus cyclopenthiazide. Only 25 patients (2%) discontinued indoramin treatment because of nonresponse, and 156 (12%) withdrew because of adverse effects, the most common being sedation, dizziness/giddiness, and headache. These results indicate that indoramin provides safe and effective blood pressure control when used as step II treatment for hypertensive patients who fail to respond to single-agent diuretic therapy.

In a multi-center, double-blind parallel-group study involving patients with essential hypertension (grade I/II), the antihypertensive effect and toleration of the postsynaptic alpha-1 receptor blocker, urapidil, was compared with that of the calcium antagonist, nifedipine. After a one-week wash-out, and one week period on placebo, the patients received either urapidil 60 mg in the morning and evening (n = 81), or nifedipine retard 20 mg mornings and evenings (n = 87), over a period of 12 weeks. The results show that urapidil and nifedipine administered alone, produce an effective lowering of blood pressure. The reduction in systolic blood pressure-approximately 12 hours after the last administration-was, on average, 10 mmHg for urapidil, and 14 mmHg for nifedipine. The reduction in systolic blood pressure was more marked under nifedipine (19 mmHg) than under urapidil (10 mmHg). The difference in heart rate at the end of the treatment phase did not differ significantly from the pre-treatment figure with either drug. The 12-week treatment with urapidil and nifedipine had no effect on lipid metabolism. Fourteen patients receiving urapidil, and 24 patients on nifedipine complained of undesirable side effects (in particular headaches and giddiness). Flushing occurred only in the nifedipine group. 8 patients on urapidil and 3 on nifedipine discontinued due to side effects.

A total of 126 patients from general practice with chronic stable angina pectoris entered the treatment phase of this open, randomized, crossover comparison of 20 mg isosorbide-5-mononitrate, and 20 mg nifedipine. Both treatments were given orally, three times daily, for 4 weeks and sublingual administration of glyceryl trinitrate was allowed throughout. Over the whole treatment period, there was no statistically significant difference between treatments for anginal attacks. However, significantly fewer glyceryl trinitrate tablets were required by patients receiving prophylaxis with nifedipine, although this difference was too small to be of clinical significance. No statistical difference existed between treatments in respect of scores for 'overall intensity of pain', 'physical exercise ability' and 'general well-being'. Of those patients who expressed a preference, the majority preferred the second treatment with no statistically significant difference between isosorbide-5-mononitrate and nifedipine. Both treatments showed similar levels of adverse events, the major difference (not significant) being for flushing of the skin which occurred in five patients given nifedipine compared with one patient given isosorbide-5-mononitrate. It is concluded that, in clinical terms, the two treatments were similar. Headache and dizziness/giddiness were the most frequently recorded adverse events.

Norfloxacin, a new oral quinolone, was compared with intramuscular spectinomycin for treating culture proved gonorrhoea (caused by penicillinase producing strains of Neisseria gonorrhoeae (PPNG) and non-PPNG strains. A total of 547 infected men and women were randomly allocated to treatment with either single dose norfloxacin (800 mg by mouth) or spectinomycin (2 g intramuscularly). Patient preference for tablets or injections was noted at this visit. Patients returned four to eight days later for assessment of efficacy, safety, and preference. Of the 482 patients who attended follow up, all those treated with norfloxacin (94 infected with PPNG strains, 145 with non-PPNG strains) and all 82 infected with PPNG strains and treated with spectinomycin were cured. Of 161 infected with non-PPNG strains and treated with spectinomycin, 159 (99%) were cured. Side effects (headache, nausea, and sleepiness) occurred in three patients receiving norfloxacin and in 17 (16 pain at injection site, 1 giddiness) receiving spectinomycin. Most patients preferred tablets to injection both on day 1 (313 v 200) and at follow up (373 v 104). This study showed that norfloxacin was a highly effective alternative to spectinomycin, produced fewer side effects, and was the preferred mode of administration.
