A randomised double blind parallel group study was performed to compare the efficacy and acceptability of slow release nifedipine (maximum dose 40 mg twice a day) with those of atenolol (maximum dose 100 mg once a day) as single agents for the treatment of essential hypertension. Of 410 patients recruited almost exclusively from general practices in 22 centres in the United Kingdom 210 received nifedipine and 200 atenolol. Both drugs significantly reduced blood pressure, and control--a reduction of the diastolic pressure to less than 95 mm Hg--was obtained in about 65% of patients. Those who received nifedipine had more pronounced reductions in systolic pressure than those who received atenolol. One hundred and forty nine patients who failed to respond adequately to either atenolol or nifedipine in low doses were given both drugs once daily for eight weeks in a fixed combination capsule that contained atenolol 50 mg and nifedipine 20 mg. All patients showed further reductions in blood pressure, although those who were taking beta atenolol before the combination capsule had more pronounced reductions in systolic pressures. Twenty six patients (12%) were withdrawn because of adverse effects while taking nifedipine compared with 19 (10%) taking atenolol. Flushing and oedema were more common after the calcium antagonist, whereas diarrhoea and dyspepsia were more common after atenolol. The frequencies of headaches, dizziness, fatigue, and dyspnoea were equally distributed between the two groups. When the fixed combination capsule was taken side effects such as flushing and oedema continued. Nifedipine was more effective than atenolol in lowering systolic blood pressure, although neither drug used alone controlled the pressure of more than two thirds of the patients studied. When used in a fixed combination slightly better control of blood pressure was achieved with a lower dose of each drug.

A randomised double-blind study was conducted to compare the efficacy of roxatidine acetate 75 mg twice daily with ranitidine 150 mg twice daily in 308 patients with endoscopically confirmed uncomplicated duodenal ulcers. After 6 weeks of treatment ulcer healing was found in 93.5% of the roxatidine acetate group and 89.2% of the ranitidine group, with no significant differences between treatment groups. The relief of day and night-time epigastric pain assessed at clinic visits or on diary cards by patients was comparable for both treatment groups, as was the consumption of antacid tablets for relief of symptoms of dyspepsia. There were no significant differences in the healing rates of smokers and non-smokers for either roxatidine acetate or ranitidine treatment, and no clinically significant alterations in laboratory values. Eight patients in the roxatidine acetate group and 1 in the ranitidine group complained of mild side effects, which included diarrhoea, constipation and headache. One patient on roxatidine acetate withdrew from treatment because of a mild skin rash. The results confirm that roxatidine acetate is a safe and effective treatment for duodenal ulcer disease.

Eighty one patients with uncomplicated hypertension who required additional antihypertensive medication (diastolic Phase V [dBP] greater than or equal to 95 mm Hg) after 4 weeks treatment with hydrochlorothiazide (HCTZ) 25 mg o.m. were randomized to receive felodipine 5 mg b.i.d. (n = 40) or propranolol (n = 41) 80 mg b.i.d. in addition to HCTZ 25 mg o.m. If the dBP measured about 12 h post-dose was not less than or equal to 90 mm Hg after 4 weeks, the dose of felodipine or propranolol was doubled. The double blind trial period was 8 weeks for all patients. Over the 8 week period, felodipine reduced the seated dBP from 100 to 83 mm Hg and propranolol from 101 to 86 mm Hg. The attained seated dBPs were significantly different in the two groups. About one third of patients in each group received the high dose of second-line therapy. After 8 weeks 91% of patients receiving HCTZ+felodipine and 84% receiving HCTZ+propranolol had a dBP less than or equal to 90 mm Hg. Both regimens were well-tolerated with an equal incidence but different pattern of adverse events (felodipine: flushing, headache and peripheral oedema; propranolol: dyspepsia, fatigue and vasospasm). In this 8-week study, felodipine and propranolol were safe and effective second-line antihypertensive drugs when added to hydrochlorothiazide. At the doses selected, felodipine was at least as effective as propranolol.

Twenty-eight Turkish refugees living in Denmark were examined by the authors in the period 1984-85. Fourteen of the persons alleged having been tortured in Turkey during the period 1980-83. The remaining 14 persons reported that they had not been tortured and thus acted as controls. All the testimonies were found valid according to a method previously used by us. The most common forms of violence reported were blows and electrical torture. Blindfolding, solitary confinement and threats were also frequent. At the time of examination the main mental complaints were sleep disturbances with nightmares and impaired memory. Emotional lability and concentration disturbances were also frequent. Physically the torture victims suffered from headache, various cardio-pulmonary and muscular pains, dyspepsia and reading disturbances. All reported that they had been healthy before torture. The clinical examination revealed only a few signs related to torture, although examples of minimal scars, fractured or missing teeth, discrete neurological disorders and mental depression were found. The 14 controls had significantly fewer complaints, and almost no abnormalities were found during the clinical examination. The present study clearly demonstrates the traumatic effects of torture.

The tolerability profile of norfloxacin, the first of a new generation of fluoroquinolone carboxylic acid antibacterials, has been defined in numerous laboratory animal and human trials. Whether administered for moderate or protracted periods, norfloxacin has been relatively safe in animals over a wide range of doses. There has been no evidence of a teratogenic effect in any of the animal species tested (rat, rabbit, mouse, monkey) at six to 50 times the human dose (400 mg twice daily). However, norfloxacin has been shown to produce embryonic loss in monkeys when given in doses 10 times the maximal human dose, resulting in peak plasma levels that are two to three times those obtained in humans. Although there are no adequate and well-controlled studies in pregnant women, norfloxacin is not recommended for use in this population because it, like other drugs in this class, causes arthropathy in immature animals. In animals, norfloxacin is neither mutagenic nor carcinogenic, and, in clinical trials, norfloxacin-related adverse experiences have been uncommon. Those that have occurred have been generally mild, requiring discontinuation of therapy in less than 1 percent of patients. The most frequently reported side effects have been nausea, dyspepsia, headache, and dizziness. Administration of 400 mg of norfloxacin at two or three times a day has been associated with reasonably good gastrointestinal tolerance.

In a cross-sectional study of 4558 Australians, it was found that the proportion of subjects reporting indigestion, palpitations, tremor, headache and insomnia increased significantly with mean caffeine intake. A multiple logistic regression model was used to show that the association between the prevalence of these symptoms and usual daily caffeine consumption remained significant in both males and females for palpitations, tremor, headache and insomnia after controlling for the potential confounding factors of age, adiposity, smoking, alcohol intake and occupation. Adiposity was strongly correlated with the prevalence of indigestion and the apparent association between caffeine and indigestion disappeared when adiposity was controlled for. According to the logistic model, the relative risk of experiencing symptoms for people consuming 240 mg of caffeine (approximately 4-5 cups of coffee or tea) per day (the population average) compared with caffeine abstainers is 1.6 for palpitations, 1.3 for tremor, 1.3 for headache, and 1.4 for insomnia in males and 1.7, 1.5, 1.2 and 1.4 respectively for females. Further logistic regression analysis indicated that the associations found between caffeine intake and symptoms did not depend on the source of caffeine. In general, coffee consumption has no significant effect over and above that attributable to its caffeine content. If these associations are causal, then approximately one quarter of the reported prevalence of palpitations, tremor, headache and insomnia is attributable to caffeine consumption in this study population.

The anti-anginal effects of KB-944 (Fostedil), a new calcium ion antagonist with a half life of approximately 23-28 hr, were evaluated in 20 patients with exertional angina pectoris in a placebo-controlled single-blind dose titration trial. Ambulatory monitoring and multistage treadmill exercise with computer-assisted electrocardiographic analysis was performed after 2 weeks of placebo therapy and after two 2-weekly periods of KB-944 therapy. The mean (+/- SEM) exercise time to the development of angina on treadmill walking increased from 6.9 +/- 0.4 min on placebo to 9.4 +/- 0.5 min on KB-944 100 mg/day (P less than 0.001) and 9.7 +/- 0.8 min on KB-944 200 mg/day (P less than 0.001 vs placebo and not significant vs KB-944 100 mg/day). The time to the development of 1 mm ST-segment depression of 5.3 +/- 0.4 min on placebo increased to 6.5 +/- 0.5 and 6.6 +/- 0.5 min on KB-944 100 and 200 mg/day, respectively (P less than 0.01 vs placebo). The heart rate at rest of 77 +/- 3 beats/min on placebo was reduced to 68 +/- 3 beats/min on KB-944 100 mg/day (P less than 0.001) and 71 +/- 2 beats/min on KB-944 200 mg/day (P less than 0.01). The maximal heart rate and the rate-pressure product were not altered by KB-944 therapy. One patient developed unstable angina during the treatment phase of KB-944 200 mg/day and was withdrawn. Five patients complained of dyspepsia and one of headache and lethargy during KB-944 200 mg/day. One patient developed ventricular tachycardia during treadmill testing while on KB-944 200 mg/day. The 24-hr ambulatory monitoring data confirmed the findings of exercise testing. KB-944 (Fostedil) in a dose of 100 mg once daily was well tolerated as compared to KB-944 200 mg once daily and both the doses were equally effective. The drug merits further evaluation for the treatment of exertional angina pectoris.

One hundred and eighty-one patients with treated Parkinson's disease completed a self-administered questionnaire on symptoms, and their responses were compared with those of 263 control subjects randomly selected from a general practice population. Nine symptoms were reported by the patients with more than a fivefold excess when compared with the controls. These included jerking of the limbs, shaking of the hands, excessive salivation, poor mental concentration, grimacing, being frozen or rooted to the spot, and hallucinations. Compared with the general control population, the patients did not have an excess of stomach or limb pain, indigestion, headache, or any decrease of interest in sex. This observational survey, unlike a randomised controlled trial, could not ensure that the different treatment groups were comparable in important respects. However, certain associations were apparent; for example, patients receiving both a decarboxylase inhibitor and levodopa tended to report fewer attacks of being frozen to the spot, fewer problems with salivation, and a reduced frequency of defaecation. Patients receiving anticholinergic drugs reported an excess of dry mouth, faintness, and dyskinesia, and fewer hot flushes.

Disturbances of memory, mood, equilibrium, and sleep that occurred simultaneously with headache and indigestion, were experienced more frequently among women working in histology who had daily exposure to formaldehyde, xylene, and toluene than in unexposed female clerical workers working in the same hospitals. Neurobehavioral symptoms were accompanied by irritation of eyes, upper airways, and trachea. Formaldehyde exposure correlated better with neurobehavioral symptoms and with respiratory and mucous membrane symptoms than did exposure to xylene/toluene or to other agents.

This article describes a data handling system designed to assess the effects of acupuncture in some common diseases. The objectives of this system are to provide a simple, swift and practical method that can be effectively operated within the limits of a busy clinic. This would provide crude descriptive data that will be of use in itself as well as suggesting further ideas for more detailed research. The system is based on the use of simple questionnaires, these are formulated so that they can be used by the patients alone. An initial form is used to record basic patient data and then one of the five symptom group forms (pain, headache, indigestion, lower bowel disorder and breathlessness) is then used to evaluate the severity of any particular disease. All the questionnaires are based on similar criteria, such as drug intake, sleep disturbance due to the disease and patient's subjective evaluation of the severity of their disease. The symptom group forms are filled in by the patient at the beginning of treatment, at the end of treatment and after a three month follow-up period. The questionnaires have been piloted on some 300 patients, and have been found to be a valid and effective method of assessing treatment.
