Gastric polyps: the case for polypectomy and endoscopic surveillance.

Thirty-two patients with gastric polyps and a mean follow-up period of 18 months were analysed. The principal presentation was epigastric pain accompanied at times by haematemesis or melaena. As in other series, the hyperplastic polyps (21 cases) predominated, followed by the adenomatous type (six patients). Endoscopy was an effective first-line investigative method for 21 patients and for a further five who had initial false negative barium studies. Gastric polypectomy was performed for 60% of patients without any complications. There was discrepancy between the biopsy material and polypectomy specimen in five of seven patients who were recalled for snaring. Although no polyp in this series turned malignant, one diffuse polyposis patient developed linitis plastica after 4.5 years of follow-up. Hence, for reasons of recurrence, new polypoid growths and development of gastric cancer, long-term surveillance is indicated.

[The value of cytoreductive second-look surgery in advanced epithelial ovarian carcinoma].

40 patients with advanced epithelial ovarian carcinoma were investigated to evaluate the influence of further cytoreduction during second-look surgery on survival after termination of first-line polychemotherapy containing cisplatinum. Radical tumorectomy with no macroscopic residual tumor mass was achieved in 27.5% of cases; in 52.5% the residual tumour mass was less than 2 cm and in 20% it was more than 2 cm in diameter after cytoreductive second-look surgery. Median survival time after second-look within these three groups of patients was 15.2 months, 16.9 months and 15.3 months, respectively (Mantel test, p = 0.74). In contrast to the situation at the diagnostic operation, further cytoreduction during second-look surgery has no positive influence on survival. We therefore abandoned this operation in clinically tumour-positive patients.

A comparative trial of flunarizine and propranolol in the prevention of migraine.

The calcium-entry blocker flunarizine (Sibelium; Janssen) was compared with the beta-adrenoreceptor-blocking agent propranolol in the prophylaxis of migraine. Fifty-eight patients were entered into a double-blind 4-month treatment trial. Patients in whom beta-blockers were contraindicated were excluded from the trial. At the end of the trial 28 patients had received 10 mg flunarizine at night during the study, 29 patients had received 60 mg propranolol 3 times a day and 1 patient was withdrawn. Both groups responded well; and there was a 4-fold drop in frequency of attacks. There was no significant difference between the two groups in terms of patient profile, onset of response to therapy, final response to therapy, incidence of dropout from the trial or incidence of side-effects. Side-effects for flunarizine were weight gain (9 patients) and tiredness (6), and for propranolol sleep disturbances including nightmares (6), tiredness (8), mental changes (e.g. irritability) (3) and weight gain (4). Both flunarizine and propranolol are useful drugs for migraine prophylaxis and can be used effectively as first-line drugs. The low incidence of generally mild side-effects with flunarizine may make it preferable to many of the agents at present in use for migraine prophylaxis.

Evaluation of a new antihypertensive agent ketanserin versus methyldopa in the treatment of essential hypertension in older patients: an international multicenter trial.

The serotonergic antagonist ketanserin (K) was compared to methyldopa (M) in a four-center international study in 119 hypertensive patients over 50 years of age. After a 4-week placebo run-in period, patients randomly received K (20-40 mg b.i.d.) or M (250-500 mg b.i.d.) for 3 months. The drugs were given in monotherapy for at least 1 month, then a diuretic could be added if blood pressure remained abnormally high. For the patients on monotherapy, active drug was replaced by placebo at the end of the 3-month period until the patients were hypertensive again. K and M had a similar effect on systolic blood pressure, but diastolic blood pressure was reduced significantly more by K than by M. Significantly more patients had their blood pressure normalized in the K group (75%) than in the M group (49%). The twice daily dosage schedule caused trough blood pressure control with both drugs. No rebound hypertension occurred at discontinuation of treatment. Monotherapy with K caused a decrease in heart rate (-5 beats/min) while M produced no change. Body weight decreased with K (-0.5 kg) and increased with M (+ 0.4 kg). No important hematological or biochemical changes were seen with either drug. Slightly fewer patients reported adverse reactions during K monotherapy (40%) than with M (45%). In the latter group mainly central side effects were observed. The data confirm K to be an effective first-line antihypertensive agent with a favorable side-effect profile.

Is first salvage chemotherapy the last-line chemotherapy in children with Hodgkin's disease? A tentative answer based on long observation of two patients.

In 82 children affected with Hodgkin's disease, in whom a complete remission was obtained, the first relapses occurred in 13 patients, their outcome was a follows: one child died of relapse and in 12 others second complete remissions were achieved. They were durable in 10 children (median, 65.5 months). Two remaining children had further relapses, their treatment consisted of four successive salvage chemotherapies. Both patients are now in their fifth complete remission. The third-line chemotherapy was already introduced 78+ months and 39+ months ago respectively. We believe that it is not possible to determine exactly the end-stage of Hodgkin's disease in those children and adolescents who have failed the first-line salvage chemotherapy.

Carvedilol for systemic hypertension.

Twenty-four hour profiles of intraarterial ambulatory blood pressure (BP) and heart rate were significantly reduced by administration of carvedilol, a new beta-blocker with vasodilating properties. Twelve patients were given carvedilol, 25 mg twice daily for 2 weeks; the dose was then increased to 50 mg twice daily if the target BP was not achieved. After 4 weeks of therapy, mean daytime reduction in BP was 25 +/- 3 mm Hg systolic and 19 +/- 3 mm Hg diastolic, and mean reduction in heart rate was 22 +/- 3 beats/min. BP at the peak of isometric exercise and during dynamic exercise was also significantly reduced. Radionuclide measurements showed that left ventricular ejection fraction was not affected by treatment, but there was a significant reduction in systolic and diastolic volumes. The drug was well tolerated. This clinical trial suggests that carvedilol will be a useful first-line drug for treatment of essential hypertension, and its vasodilating action may have a more favorable effect on left ventricular function than conventional beta-blocking drugs.

Long-term hypotensive treatment with nitrendipine in mild to moderate essential hypertension: preliminary results of a placebo-controlled study versus atenolol.

Nitrendipine is a dihydropyridine calcium antagonist suggested to be a new drug for first-line antihypertensive therapy, possibly active in once-daily administration. In the present study the acute and long-term hypotensive effects of nitrendipine have been evaluated in comparison with those of atenolol in a randomized, double-blind, clinical trial. Twenty-four patients have been studied, and the effects of treatment have been evaluated both at rest and during psychological and physiological stresses. Hemodynamic noninvasive parameters have also been obtained, at rest and during mental arithmetic tests, by a continuous-wave Doppler technique. Preliminary results about the first 13 consecutive patients are reported here. Nitrendipine induced a highly significant acute hypotensive effect (2 h after drug administration), whereas no effect was observed for atenolol except for heart rate. During chronic treatment (5 weeks), nitrendipine showed less hypotensive effect than atenolol when BP values 24 h after the last administration were analyzed, but significantly more effect when values obtained 2 h after drug administration were evaluated. These findings confirm that nitrendipine is effective in decreasing blood pressure, but the once-daily administration may not bring about the maximum effect in all patients. Interesting aspects of this drug, which make the clinical use of this compound safe, are represented by apparent lack in tolerance and rebound, and by the moderate increase in cardiac output associated with the treatment.

European experience with ifosfamide in lymphomas.

In malignant lymphomas, ifosfamide-containing regimens were at first used mainly in second-line therapy and response-adapted protocols. Currently, in combination with other drugs, ifosfamide is being used in several phase-III trials. As salvage therapy in non-Hodgkin's lymphoma (NHL), IMV-Bleo (ifosfamide, methotrexate, etoposide, bleomycin) produced a complete remission (CR) rate of 41% and seemed to be particularly effective in patients with suboptimal response to first-line treatment. IBEP (ifosfamide, bleomycin, etoposide, procarbazine), in combination with procarbazine and bleomycin was an effective non-cross-resistant alternative in CHOP (cyclophosphamide, hydroxydauomycin/doxorubicin, vincristine, prednisone)-refractory NHL. In a trial of response-oriented therapy in high-grade malignant lymphoma patients, the investigators concluded that consolidation therapy was necessary even in patients with rapid response to CHOP. Patients with NHL resistant to or relapsing from conventional chemotherapy or with MOPP-ABVD (mechlorethamine, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, vinblastine, decarbazine)-resistant Hodgkin's disease (HD) were treated with BMV-VIP [bleomycin, plus high-dose methylprednisolone plus ifosfamide, etoposide, plus methylprednisolone]. In high-grade malignant NHL, patients received three cycles of COP-BLAM (cyclophosphamide, vincristine, procarbazine, prednisone, bleomycin, doxorubicin). Those who achieved CR received two more cycles of COP-BLAM and IMV (ifosfamide, methotrexate, etoposide) as consolidation therapy. Patients in partial remission (PR) or with less of a response to COP-BLAM were switched to IMV. After reaching CR, patients received two additional cycles as consolidation therapy. After the second restaging, patients were randomized to observation v additional radiotherapy. Of 191 patients, 148 have passed first restaging with 51% in CR; 85 went through the second restaging with 61% in CR. Of 32 patients who only reached PR after the first restaging, 15 (47%) achieved CR with IMV. For primary treatment of HD, the German Hodgkin Study Group added a third non-cross-resistant regimen, IMEP (ifosfamide, methotrexate, etoposide, prednisone), to supplement COPP (cyclophosphamide, vincristine, procarbazine, prednisone) and ABV in the primary treatment of HD. In a pilot study, 87% of 63 evaluable patients reached CR. The current phase-III protocol is comparing COPP/ABVD with fast alternating cycles of COPP/ABV/IMEP.

Age-related effects of antihypertensive therapy with alpha-blockers.

Currently, the most important alpha-blockers used in treating hypertension are prazosin and its long-acting congeners, doxazosin and terazosin. Although there are minor age-related changes in the pharmacokinetics of these compounds, they result in no appreciable alteration in dose requirements. Overall, published evidence does not indicate any loss of responsiveness to alpha-blockade in the elderly. Despite the potential risks of first-dose hypotension and of postural hypotension, long-acting alpha-blockers may warrant further consideration as possible first-line therapy in elderly hypertensive patients. These agents allow the simplicity of once-daily dosing, and their cardiac and metabolic effects offer potential advantages.

An overview of integration of therapy for congestive heart failure.

Patients with symptoms of congestive heart failure look to treatment to relieve symptoms, improve the quality of life, and prolong life. They prefer a convenient dosing schedule, with minimal side effects and low cost. A wide variety of agents are available to treat patients with congestive heart failure. The three major classes of drugs that improve heart failure include the diuretics, inotropic drugs, and vasodilators. It appears that any one of these three classes are potential first-line candidates for treating patients with congestive heart failure. Patients with edema usually require long-term therapy with diuretic agents. Since the vasodilators are the only class of drugs which have been shown to prolong life, they should be used routinely in the management of patients with congestive heart failure. Since all three classes of drugs have additive beneficial hemodynamic effects, it makes sense to consider the use of all three in patients with at least moderate to severe heart failure. At the moment unanswered questions include the role of antiarrhythmic agents in reducing the incidence of sudden death, and the use of potent new inotropic vasodilators. Overall, the current therapeutic approach to patients with heart failure is effective in relieving symptoms, improving exercise tolerance and in prolonging life.

The effect of dihydropyridine calcium antagonists in hypertensive patients with impaired renal function.

Dihydropyridine calcium antagonists play an important role in the treatment of arterial hypertension. In many centers, they are used as first-line treatment. Since impaired renal function can be a complication of long-standing blood pressure elevation, the usefulness of dihydropyridine calcium antagonists in hypertensive patients with reduced glomerular filtration rate is an important clinical issue. Several studies of the pharmacokinetics of calcium antagonists, such as nifedipine and related compounds, clearly show that the important pharmacokinetic variables are not affected by impaired renal function. Moreover, the antihypertensive efficacy is not reduced in patients with reduced glomerular filtration rate. A matter of potentially great clinical importance is the fact that several studies have shown that treatment with dihydropyridine calcium antagonists in patients with impaired renal function has reduced the rate of deterioration in filtration rate, leading to a preservation of renal function. It can therefore be concluded that dihydropyridine calcium antagonists are useful in the treatment of hypertensive patients with impaired renal function, that the major pharmacokinetic and pharmacodynamic variables are not negatively affected, in particular that the antihypertensive effect is maintained in such patients, and that there is no retention of metabolites. Finally, the observation that the decline in renal function can be slowed down suggests that dihydropyridine calcium antagonists may be the preferential treatment in hypertensive patients with reduced renal function.

Drug prescribing in rheumatoid arthritis in Otago.

The drug therapy prescribed for a group of 50 patients with rheumatoid arthritis in Otago prior to specialist referral was examined. Thirty-two patients were receiving some first-line anti-inflammatory drugs and six were receiving no therapy at the time of their first hospital clinic visit. Salicylates had been prescribed first in only 16 of the 50 patients while this drug had been withdrawn because of side effects in about one-third of the patients who had been treated with it prior to specialist referral. Seven patients had received phenylbutazone and six corticosteroids as the first treatment for their rheumatoid arthritis. About one-third of the patients were receiving more than one anti-inflammatory drug at the time of their initial clinic visit.

Bretylium tosylate: a review.

The chemistry, pharmacology, pharmacokinetics, clinical uses, adverse effects, drug interactions and dosage of bretylium tosylate, a recently approved antiarrhythmic agent, are reviewed. Bretylium tosylate is used to treat life-threatening ventricular arrhythmias, principally ventricular fibrillation and ventricular tachycardia, that have not responded to treatment with first-line antiarrhythmic agents. The drug has a direct positive inotropic effect on the myocardium and blocking effect on postganglionic sympathetic nerve transmission. The drug is poorly absorbed orally, requiring either i.m. or i.v. administration. Drug excretion occurs primarily through the kidney, necessitating dosage modification in renal disease. Hypotension is the most commonly observed adverse reaction to bretylium tosylate. Rapid i.v. administration may cause severe nausea and vomiting, and i.m. injection at the same site may cause atrophy and necrosis of muscle tissue. Quinidine and procainamide may potentiate the hypotensive effects of bretylium. Bretylium will aggravate digitalis-induced arrhythmias. Bretylium's use in resistant ventricular tachyarrhythmias requires close clinical monitoring.

[Current chemotherapy of pulmonary tuberculosis].

Tuberculosis has today lost much of its dread for mankind: in 1976, 1823 persons contracted tuberculosis and 182 died of pulmonary tuberculosis in Switzerland. In contrast, 1375 died of pneumonia, 1309 of non-specific airway disease and 2202 of bronchial cancer in the same year. The present data on morbidity and mortality in Switzerland resemble those of the other industrial European countries or the USA. The decrease in morbidity and mortality of pulmonary tuberculosis was caused-among other factors-by chemotherapy. Chemotherapy not only profoundly changed the infectivity of tuberculous patients and made ambulatory, domiciliary treatment possible, but cured pulmonary tuberculosis. The introduction of the bactericidal rifampicin led to the latest major landmark in the chemotherapy of tuberculosis in the past 20 years: namely, short-course chemotherapy. Together with the other first-line drugs (isoniazid, streptomycin, ethambutol), rifampicin shortened the duration of chemotherapy from 18--24 to 9--12 months. Short-course chemotherapy is today the therapy of choice for most patients with pulmonary tuberculosis.

[Tics and Tourette Syndrome].

Tics disorders and Tourette syndrome (TS) are neurodevelopmental conditions characterized by motor and/or vocal tics with onset in childhood. Their clinical presentation is heterogeneous and fluctuating over time, with exacerbations related to emotional, environmental, and medical factors. Diagnosis is clinical and based on medical history and neurological examination, following DSM-5-TR criteria, with ancillary testing rarely required. The prevalence of TS is estimated at 0.7%, while transient tic disorders affect up to 10% of children. The natural history is generally favorable, with symptom improvement during adolescence, although a subset of patients continues to experience tics into adulthood. Most individuals with TS present psychiatric comorbidities, particularly attention-deficit/hyperactivity disorder and obsessive-compulsive disorder, which significantly impact quality of life and should be prioritized in management decisions. Treatment is recommended only when tics cause functional impairment and follows a stepwise approach including psychoeducation, behavioral interventions, and individualized pharmacological therapy. Comprehensive behavioral intervention for tics is considered first-line treatment when available. Alpha-2 adrenergic agonists and dopamine antagonists are the most commonly used pharmacological options. Neuromodulation therapies are reserved for severe, refractory cases. These recommendations from the Ibero-American Academy of Pediatric Neurology summarize current evidence and provide a practical, updated framework for the diagnosis and management of tic disorders and Tourette syndrome in pediatric patients.

Rheumatoid arthritis.

Management should help relieve symptoms, increase or maintain function, produce few side effects and keep the cost to a minimum. Aspirin remains the first-line drug; other nonsteroidal anti-inflammatory drugs may be useful when aspirin cannot be tolerated. Symptoms and signs of rheumatoid disease may be suppressed by corticosteroids, but only gold compounds, penicillamine and cytotoxic therapy have been shown to decrease disease activity and lessen permanent joint damage.

Role of DTIC (NSC-45388) in the chemotherapy of sarcomas.

DTIC was one of the first of several new agents evaluated by the Southwest Oncology Group (SWOG) and the M.D. Anderson Hospital and Tumor Institute (MDAH) in the therapy of adult patients with metastatic sarcomas. It yielded an overall response rate of 17%. This is similar to that seen in a review of 138 patients who represent the total number reported in either published or unpublished data. The subsequent addition of DTIC to adriamycin in several studies carried out at the MDAH and in the SWOG has increased the complete and partial remission rate over that seen with adriamycin alone, and more importantly has increased remission duration and survival. DTIC is currently used in combination with adriamycin in the first-line therapy of patients with metastatic sarcomas and should be considered for patients who have relapsed on primary therapy not including DTIC.

Present state of cardiovascular community control programme in the Czech Socialist Republic.

The high incidence, great import, and long duration of cardiovascular diseases are reflected in high demands placed on the health services. Experience shows that utilization of the results of research in general practice is lagging behind. The application of any improvement in the diagnosis, therapy, and prevention in health care waits several years for its accomplishment. In order to improve this situation, the Ministry of Health of the CSR constituted, in line with WHO recommendations, a Department for Cardiovascular Diseases Control. The Department has worked out a programme of prevention and control of the major cardiovascular diseases, in particular, ischaemic heart disease, systemic hypertension and its complications, rheumatic heart disease, congenital cardiac and vascular defects, and cor pulmonale. New diagnostic, therapeutic, and preventive procedures are first tried out in so-called model areas and are only after this introduced into the national health care of people suffering from or endangered by cardiovascular diseases. In parallel, organizational measures necessary for comprehensive care are implemented. The authors report on the experience gained so far with the realization of the programme of care of people suffering from IHD and acute myocardial infarction. They emphasize the importance of continual schooling of medical personnel and of health education of the entire population. They describe the implementation on a national scale of postgraduate cardiological courses intended especially for first-line doctors.
