In a field study comprising 678 patients with arterial hypertension efficacy and tolerance of the stable combination VKB 105 consisting of 10 mg Pindolol (Visken) and 5 mg Clopamid (Brinaldix) were investigated. Treatment with 1--2 tablets of VKB per day resulted in a successful therapy in 94% of all patients corresponding on the average to a reduction in blood pressure to 145/85 mm Hg within 14 days. In mean arterial pressures ranging between 120 and 170 mm Hg a positive linear relationship between the individual initial value and the hypotensive effect of the combination could be observed. A controlled omission trial disclosed qualitatively the respective contribution to the effect of the two components Pindolol and Clopamid. With a systematic case control of the serum potassium under the combined therapy with VKB 105 and during a monotherapy with Clopamid and antihypokalaemic effect of Pindolol could be demonstrated diminishing the tendency for potassium loss. The result revealed a far-reaching potassium neutrality of diuresis-depending stimulation of renin by the beta-receptor blocker. In 61 patients altogether subjective side-effects could be recorded, such as vertigo (5%), palpitations (2.8%), fatigue (2%), insomina (1.9%), nausea (1.7%) and vomiting (0.8%). Laboratory controls gave no indication for clinically relevant changes.

224 patients with coronary heart disease, hypertension, disturbances of cardiac rhythm or hyperkinetic heart syndrome were treated with the cardioselective beta-blocker Talinolol (Cordanum) for a period up to 3 years. In 239 examinations in intravenous or peroral application of this medicament we controlled among others the appearance of side effects. This test was carried out with the help of standardised questionings and clinical controls. Apart from registrations of ECG and blood pressure clinico-chemical investigations were included and in the long-term experiment also tests by dermatologists, otorhinolaryngologists and ophthalmologists. In the total number of patients the proportion of side appearances was 17,6%, in the long-term experiment (100 patients with on an average 12.9 months) 7%. The symptoms most frequently cited in the initial phase, such as fatigue, weakness, insomnia and nausea receded within 4 weeks apart from few exceptions. There did not appear any essential bradycardic disturbances of the cardiac rhythm, just as little were references to disadvantageous reactions in the sense of a practolol syndrome.

Three new cases of chronic vitamin A intoxication are reported and a review of the literature with special reference to chronic intoxication in adolescents and adults is presented. The most prominent features are intracranial hypertension, skin and hair deviations, pain in the musculoskeletal system, and fatigue. Intracranial hypertension occurs in 50% of chronic intoxications, but is not invariably linked with the other symptoms. Young women are the major age group represented. There seems to be no relation between the severity of the clinical picture and the vitamin A serum level. Discontinuance of vitamin A intake is sufficient for cure.

A questionnaire study on work conditions, work organization, leisure time, social problems, and health was directed toward active and retired locomotive engineers. This article mainly presents responses of the active engineers. The active locomotive engineers quoted the irregular work hours as the worst occupational problem. They judged noise and vibration in the locomotive cabs as disturbing. The majority of the desired changes in the work and work conditions concerned work time. The most common complaints given on the questionnaire were back trouble, hypertension and dermatitis. Tiredness and exhaustion were the most prevalent neuropsychological symptoms. A retrospective follow-up survey on invalidity and mortality was made. Trainmen and railroad clerks were used as reference cohorts.The engineers had relatively high invalidity and mortality rates in comparison to the reference groups, especially with respect to cardiovascular diseases and malignant tumors. Higher rates for disease of the digestive system and hearing loss were also suggested by the results.

Fifty-five patients with mild to moderately severe essential hypertension were treated with guanabenz (2, 6-dichlorobenzylidene aminoguanidine acetate) in doses from 4 to 16 mg twice daily in a randomized, placebo-controlled study. The patients treated with placebo in the initial phase of the study were subsequently treated with guanabenz. The mean arterial pressure in the guanabenz group decreased from 130.6 to 107.6; that in the placebo group decreased from 129.6 to 126.6 standing and from 126.6 tp 109.9 and 128.8 to 120.5, respectively, supine. The principle adverse effects included sedation, dry mouth, weakness, and tiredness. Of the guanabenz-treated patients 84% had sustained decrease in supine diastolic blood pressure of 10 mm Hg or more, whereas in the placebo-treated patients only 32% had such a response. There was no significant orthostatic hypotension. Guanabenz thus appears to be an effective antihypertensive drug in patients with mild to moderately severe hypertension.

A total of 242 women with moderate hypertension in pregnancy completed a controlled trial of methyldopa (Aldomet). The hypotensive effect of methyldopa was similar to its action in non-pregnant individuals and greatly reduced the frequency of severe hypertension occurring antenatally and in labour. As pregnancy advanced, an increasing daily dose of methyldopa was needed and there was a greater use of additional hypotensive therapy. Seventeen (14-5 per cent) women assigned to methyldopa had to be transferred to another drug or had to stop treatment completely because of minor side effects, of which the commonest were lack of energy and dizziness. No serious side effects were encountered. Nine per cent of the untreated women developed severe hypertension which required treatment later in their pregnancies. Six weeks after delivery, nearly all the patients were able to stop treatment.

A double-blind, crossover, multicentre study of 98 previously untreated patients with mild to moderate essential hypertension was carried out in general practice to assess the effect of 50 mg, 100 mg, and 200 mg atenolol, given once daily, compared with that of placebo over a period of 4 weeks each. At the end of the double-blind phase, all patients took 100 mg atenolol daily for a further 8 weeks. All three doses of atenolol produced statistically significant falls in systolic and diastolic pressure and pulse rate (p less than 0.001). The lowest pressures were achieved with 100 mg daily; a difference of 22/15 mmHg at the end of the double-bling phase, and a difference of 25/16 mmHg at the final observation. Body weight, blood urea, blood uric acid, and serum electrolytes remained within normal limits throughout the study. The incidence of side-effects with 50 mg and 100 mg atenolol was not significantly different from that caused by placebo, but the incidence of tiredness at the 200 mg dose level was greater than that caused by placebo and by the lower doses. The incidence of possible side-effects elicited by a questionnaire was low, the greatest number being volunteered by patients taking placebo. It is concluded that the optimal dose of atenolol for treating patients with mild to moderate hypertension in general practice is 100 mg daily.

Fourty-six men and 6 women aged 45 years and having arterial hypertension newly diagnosed at routine medical examinations were given out-patient antihypertensive treatment with prazosin, prazosin + hydrochlorothiazide, or prazosin + hydrochlorothiazide + clonidine. The mean values of blood pressure after the 3-week placebo period were 157/109 mmHg in the supine and 160/115 mmHg in the standing position. Treatment with prazosin (1--2 mg t.i.d.) produced normotension in 4/52 patients only, yet supine diastolic blood pressure and standing blood pressure were significantly lowered within 9 weeks. The addition of hydrochlorothiazide (25 mg daily) for 3 weeks to the regimen led to normotension in 12/46 patients. The remaining 34 patients still having an average supine blood pressure of 152/106 mmHg after prazosin + hydrochlorothiazide, responded well to low doses of clonidine added for 6 weeks to the treatment. Only 7 patients having initially high blood pressure still had a diastolic blood pressure greater than or equal to 100 mmHg at the end of the trial. The subjective side-effects were frequent but mild being roughly similar during placebo and active drug periods, except that fatigue and dry mouth due to clonidine were common, yet tolerable. No "first tablet reactions" to low inital doses of prazosin were found.

A large, open, multi-centre study was carried out in general practice to evaluate the effectiveness and tolerance of a combination of 10 mg pindolol plus 5 mg clopamide, in single tablet form, in the treatment of patients with essential hypertension. Computer analysis of the records of 8989 patients who completed the 8-weeks' study period showed that treatment with the combination product, in a dosage of 1 tablet daily in 83% of the patients, resulted in excellent blood pressure control in the majority (75%) of cases, irrespective of age or previous antihypertensive treatment, and was particularly effective in those with mild to moderate hypertension who had previously not received any therapy. Side-effects were generally not troublesome and only 8.3% of patients stopped treatment for this reason. The most commonly reported side-effects were dizziness, nausea, tiredness and headache.

Pulmonary emboli seldom recur, and when recurrence does occur it is not associated with permanent sequelae unless there is progressive pulmonary arterial hypertension. Five patients with clinical and perfusion lung scan evidence of recurrent pulmonary embolism presented with abnormal cardiac rhythms without evidence of progressive pulmonary hypertension. Twenty-four-hour ambulatory electrocardiographic monitoring was valuable in diagnosis and in assessing the effectiveness of treatment. Although palpitation was the main complaint, other symptoms included tiredness, mild exertional dyspnoea, and chest discomfort unrelated to effort. Symptomatic improvement coincided with objective evidence of improvement from repeat lung scans and 24-hour ECG records. Antiarrhythmic agents controlled the arrhythmias but were subsequently withdrawn without the return of symptoms. Four of the five patients continued to take anticoagulants for two years. We believe that these five patients represent a group of patients with recurrent pulmonary emboli and a recognisable clinical picture dominated by arrhythmias unrelated to progressive pulmonary arterial hypertension. Long-term anticoagulant treatment was associated with clinical improvement.
