Isradipine (Lomir) a new dihydropyridine calcium antagonist was evaluated for its efficacy, tolerability and safety among mild to moderate Tanzanian hypertensives. Twenty nine patients (7 males and 22 females), mean age 42.7 +/- 8.5 years entered active treatment phase, of the 16 week open label therapeutic trial. A mean decrease from base line in supine systolic blood pressure (SBP) of 17.6 mmHg (p < 0.001) and diastolic blood pressure (DBP) of 13.5 mmHg (p < 0.001) were achieved at the end of the study period. The corresponding changes from base line in standing SBP and DBP were 18 mmHg (p < 0.001) and 13.5 mmHg (p < 0.001) respectively. The efficacy was excellent or good in 84% and fair or none in 16% of the study patients. The tolerability of the drugs was excellent or good in 88.8% of patients, fair in 7.4% and bad in 3.8%. The mild side effects included headache, palpitations, tiredness and nocturia. But these improved with continued treatment. Isradipine (Lomir) at a dose of 1.25mg to 2.5mg twice daily is effective, safe and tolerable in mild to moderate hypertension.

In a 16 weeks open label therapeutic trial, studies were performed on isradipine (Lomir) to evaluate its haematological and biochemical safety and hypotensive capacity in the management of adult black hypertensive patients. The mean sitting diastolic blood pressure decreased from 105.5 +/- 9.66 mm hg at the end of the washout period to 92.1 +/- 7.59 mm hg at the end of the study, p less than 0.0001; while the mean standing diastolic blood pressure was 108.0 +/- 7.10 mm hg and 93.9 +/- 8.4 mm hg at the end of the washout phase and at the completion of the therapy respectively, p less than 0.0001. The corresponding mean sitting systolic blood pressures were 155.4 +/- 9.91 mm hg and 140.6 +/- 9.47 mm hg, p less than 0.001 while the corresponding mean standing systolic blood pressures were 156.6 +/- 12.50 mm hg and 142.6 +/- 9.15 mm hg, p less than 0.001. There were negligible changes in the mean heart rate; from 79.5 +/- 9.23 beats per minute (bpm) at the end of the placebo phase to 78.2 +/- 9.15 bpm at the end of the study in the sitting position, p greater than 0.1. The corresponding mean standing values of heart rate were 82.5 +/- 11.33 and 78.6 +/- 8.76, p greater than 0.5. The haematological, biochemical and electrocardiographic parameters remained within normal limits during the study. Side effects were mild, transitory, improved with therapy and consisted of dizziness, palpitations, headache, nocturia, tiredness and fainting attacks. The study achieved 96% good-to-excellent results with respect to both efficacy and tolerability. Isradipine (Lomir) is therefore an efficacious and safe antihypertensive agent in the management of black adult patients with mild to moderate primary arterial hypertension when administered in the dose of upto 2.5 mg twice daily alone or in combination with a beta-blocker.

Several recent articles question whether patients with asymptomatic hyperparathyroidism and minimal hypercalcemia should be treated by parathyroidectomy. We therefore reviewed our experience in 103 consecutive patients with primary hyperparathyroidism who were treated by parathyroidectomy to determine, first, how many of these patients had asymptomatic or symptomatic hyperparathyroidism, and second, did these patients benefit from parathyroidectomy? We also analyzed the safety of parathyroidectomy in 426 consecutive patients, including 79 who required reoperation for hyperparathyroidism, specifically looking for complications and the outcome of these procedures. Our study documents the following: (1) only 2 of 103 (2%) patients referred for parathyroidectomy had "true" asymptomatic hyperparathyroidism; (2) only symptoms of fatigue, bone pain, and weight loss correlated with the degree of hypercalcemia, whereas muscular weakness, psychiatric symptoms, nocturia, polyuria, recent memory loss, constipation, and nephrolithiasis did not; (3) only 1 of 15 patients who were referred as asymptomatic were truly asymptomatic after more thorough questioning, and all 14 improved following parathyroidectomy; (4) 81% of the patients who were referred with symptoms improved following parathyroidectomy; and (5) permanent complications occurred in only 4 patients. All but 1 had reoperations for persistent or recurrent hyperparathyroidism (3 vocal cord paralyses and 1 hypoparathyroidism requiring autotransplantation of cryopreserved parathyroid tissue). There was 1 death of an 84-year-old woman with hypercalcemic crisis. Thus, most patients with hyperparathyroidism are symptomatic and benefit symptomatically and metabolically from parathyroidectomy, which is a safe operation.

A hypertensive urgency should be distinguished from a hypertensive emergency. Although the distinction may not always be obvious, certain guidelines may help the clinician determine which therapeutic approaches are most appropriate for each patient. Hypertensive emergencies include those conditions in which new or progressive severe end-organ damage is present and a delay in appropriate therapy might result in permanent damage, progression of complications, and a poor prognosis. Hypertensive urgencies include those conditions with minimal to no obvious end-organ damage in which blood pressure should be lowered expeditiously. The risk of immediate complications or organ damage is less likely to occur, and thus the immediate prognosis is better, although the ultimate prognosis, if untreated, is poor. There is a marked individual, racial, sexual, and age difference in the ability to tolerate high intraarterial pressure, as evidenced by patients' symptoms and signs of end-organ damage. Patients may have no symptoms of elevated blood pressure until significant intraarterial levels are reached. If symptoms are present, they may include headache, dizziness, blurred vision, shortness of breath (especially with exertion), chest pain, rapid pulse, palpitations, malaise and fatigue, nocturia, or pedal edema. Signs of hypertensive disease vary and depend not only on the level of blood pressure but also include funduscopic changes with arteriolar narrowing, atrioventricular nicking, hemorrhages, exudates or papilledema, central nervous system changes and neurologic abnormalities, cardiac changes with gallop rhythm, cardiomegaly, tachycardia, ectopic ventricular beats, left ventricular hypertrophy or signs of congestive heart failure, pulmonary edema, and signs of renal insufficiency.(ABSTRACT TRUNCATED AT 250 WORDS)

In 100 patients with irritable bowel syndrome a wide variety of non-gastrointestinal symptoms were significantly more common than in a group of 100 age, sex, and social class matched controls. Nocturia, frequency and urgency of micturition, incomplete bladder emptying, back pain, an unpleasant taste in the mouth, a constant feeling of tiredness and in women dyspareunia were particularly prominent (p less than 0.001). With reference to non-colonic gastrointestinal symptoms nausea, vomiting, dysphagia and early satiety were very common (p less than 0.0001). This symptom diversity was observed irrespective of whether the patient had a psychiatric disorder or not. Patients smoked more than controls (p = 0.02) drank more caffeine containing drinks (p = 0.03) and 26% had taken at least one week off work in the previous 12 months. Thirty three per cent of patients had a family history of irritable bowel syndrome. Cognisance of these diverse symptoms may prevent referral to the wrong medical specialty and inappropriate investigation. They may also be indicative of a much more diffuse disorder of smooth muscle than has previously been appreciated.

Labetalol, a new alpha- and beta-adrenergic blocking agent, was administered to 57 patients with essential hypertension whose standing diastolic blood pressure was 105 to 120 mm Hg after three and four weeks of placebo therapy and greater than 90 mm Hg after three to four weeks of therapy with hydrochlorothiazide, 25 mg twice a day. Patients were then randomly assigned on a double-blind basis to receive either labetalol, 100 mg twice a day, or placebo combined with hydrochlorothiazide. Thereafter, the dose of labetalol was titrated weekly in both groups to a maximum of 400 mg twice a day to achieve a standing diastolic blood pressure of less than 90 mm Hg that was also decreased from the hydrochlorothiazide baseline by 10 mm Hg or more (therapeutic goal). Labetalol was abruptly discontinued after four weeks of treatment and patients were given hydrochlorothiazide alone for two additional weeks. After one week of labetalol therapy, 100 mg twice a day (added to hydrochlorothiazide), there was a significantly greater reduction in supine systolic/diastolic blood pressure (6/5 mm Hg, p less than 0.04/less than 0.03) and standing blood pressure (9/7 mm Hg, p less than 0.01/less than 0.01) than with placebo therapy (3/0.5 and 3/1 mm Hg, respectively). The blood pressure reduction in the labetalol-treated group was associated with a 4 and 5 beats per minute reduction in the supine and standing heart rates, respectively. The median labetalol dose required to achieve the standing diastolic blood pressure goal was 400 mg twice a day. After four weeks of labetalol treatment, the mean reduction in blood pressure from the hydrochlorothiazide baseline was 12/13 mm Hg (p less than 0.01/0.01) in the standing position and 8/8 mm Hg (p less than 0.01/0.01) in the supine position. These blood pressure reductions were accompanied by a mean reduction in heart rate of 7 beats per minute. The most frequently reported complaints other than thiazide-induced nocturia included dizziness, fatigue, nausea, rash, and/or pruritus. Most of these complaints were reported at a similar incidence while patients were receiving placebo or hydrochlorothiazide alone as when receiving labetalol with hydrochlorothiazide. After abrupt withdrawal of labetalol, no evidence of rebound hypertension was observed. Labetalol is a safe and effective step II drug when added to hydrochlorothiazide for the treatment of patients with moderate to moderately severe hypertension.

More than 1200 patients who received pindolol for the treatment of hypertension, angina pectoris, and various arrhythmias in studies conducted in the United States were included in the New Drug Application submitted to the FDA. Nearly 1000 of these patients received pindolol as monotherapy. The side effects reported were generally transient and of mild or moderate severity. The most frequently reported side effects seen after pindolol administration, compared to those seen after placebo, were in decreasing order of incidence: headache, dizziness, insomnia, muscle pain, fatigue, weakness, nervousness, joint pain, edema, nausea, and muscle cramps. Other side effects that occurred more frequently with pindolol than with placebo but at a rather low incidence induced weight gain, bizarre dreams, visual disturbances, lethargy, and diarrhea. Nasal congestion, throat discomfort, nocturia, impotence, pruritus, anxiety, hypotension, bradycardia, and heart failure occurred only rarely. Of the 323 patients who received pindolol alone for the treatment of mild to moderate hypertension, only 20 (6.2%) were withdrawn from the study because of side effects. Overall, 3.4% of the patients treated with pindolol were withdrawn because of side effects, most of which involved the central nervous system, that is, insomnia, anxiety, dizziness, and headache. However, a few patients manifested some edema and weight gain while receiving pindolol alone. Review of the side effects data did not reveal a tendency for the incidence of side effects to be dose related. One placebo-controlled, double-blind study designed to evaluate the fixed dosages of 15, 30, and 60 mg in the treatment of mild to moderate hypertension suggested that only the incidences of insomnia and nervousness increased with increasing doses. However, these side effects were generally transient and of mild or moderate severity. The evidence indicates that pindolol has an acceptable safety profile and that any side effects that appear are generally well tolerated and disappear with continued treatment.

The objective of this questionnaire-based survey was to evaluate the prevalence and causes of sleep disturbances in 90 nondepressive patients with Parkinson's disease (PD) and 71 age-matched healthy subjects. We also assessed the prevalence and characteristics of excessive daytime sleepiness (both groups) and excessive fatigue (PD patients). A high prevalence of sleep disturbances in PD patients was found; this is to a large extent probably the result of aging. As compared with controls, patients had a more severely disturbed sleep maintenance because of nycturia, pain, stiffness, and problems with turning in bed. The prevalence of excessive dreaming is similar in both groups, but altered dream experiences almost exclusively occurred in PD. Patients rated themselves more often to be morning-types than controls. This finding may account for the reported adaptation effects in experimental settings and the reduced REM latency in PD patients. The prevalence of daytime sleepiness was similar in both groups. Excessive daytime sleepiness showed a clear diurnal pattern with a peak in the early afternoon. As for excessive fatigue, the majority of the patients did not report a preferential time for this symptom. Our findings further argue against an association of fatigue with any circadian factor, and instead suggest a relationship with the motor deficits of PD.

In a post-marketing surveillance study of 752 patients suffering from urgent incontinence, mixed urgent-stress incontinence, reflex incontinence, urgency and enuresis were treated with propiverine hydrochloride. Clinical efficacy of propiverine hydrochloride was verified by the improvement of symptoms related to detrusor hyperactivity, hypersensitivity and hyperreflexia during a 12-week surveillance period: daytime and overnight urinary incontinence, as well as the frequency, nocturia, urgency in day time and at night decreased. These results are well demonstrated by decreased pad use and statistically significant decrease of Gaudenz urgency score during treatment, confirming the efficacy of propiverine hydrochloride already proved in clinical trials. The safety profile of propiverine hydrochloride displayed characteristic anticholinergic symptoms (dry mouth, accommodation disorders, constipation, tiredness, dizziness) with decreasing incidence during the 12-week treatment period. The residual urine volume decreased also. Serious adverse events were observed rarely and could be explained by the lack of consideration of contraindications, warnings and interactions with other drugs. The positive risk-benefit relationship of propiverine hydrochloride in the treatment of detrusor hyperactivity, hypersensitivity and hyperreflexia was reconfirmed in this post-marketing drug surveillance study.

The long term impact of pre-hospital thrombolysis in acute myocardial infarction on the subsequent development of heart failure symptoms was investigated in 362 consecutive patients. The pre hospital strategy, used in 61 patients, allowed for very early administration of streptokinase, within 1.2+/-0.6 (mean+/-S.D.) hours from pain onset. In contrast, 294 patients treated in hospital received lytic treatment within 2.0+/-0.9 hours. The pre hospital group showed faster reperfusion, as measured by the time to peak creatine kinase and to ST segment recovery, but only a slightly better ventricular function, as compared to hospital treated patients. Heart failure symptoms were significantly reduced in the pre hospital group during hospitalization and at long term follow up: there were less dyspnea, fatigue, orthopnea, nocturnal dyspnea, nocturia, peripheral edema and episodes of pulmonary edema. Angina was reduced as well. We conclude that the initial benefit of prehospital thrombolysis translates into long term reduction of heart failure symptoms, thus improving quality of life.
