Metabolic effects of ramipril treatment in hypertensive subjects with non-insulin-dependent diabetes mellitus.

The antihypertensive and metabolic effects of the new long-acting angiotensin converting enzyme (ACE) inhibitor, ramipril (Hoe 498), were assessed in 21 patients with non-insulin-dependent diabetes mellitus (NIDDM) over a 12-week treatment period. In an average dose of 5 mg given once daily, ramipril effectively reduced the elevated blood pressure. In 74% of the cases systolic and diastolic blood pressure was normalised during monotherapy. Mean blood glucose and glycosylated hemoglobin (HbAI) values showed a slight but significant (p less than 0.05) decrease at the end of the ramipril treatment period (glucose: 8.5 +/- 1.4 mmol/l vs 8.0 +/- 0.9 mmol/l; HbAI: 10.0 +/- 1.3% vs 9.7 +/- 1.1%). C-peptide levels did not change. Since there was also a small reduction of body weight during treatment, the observed hypoglycemic response could not be fully ascribed to ramipril. Also, a reduction in total cholesterol and an increase of HDL cholesterol could be documented during treatment with ramipril. The reduction in body weight could also be made partly responsible for this positive effect on lipid metabolism. No serious side effects were reported during the entire study period. Due to these beneficial effects, ramipril can be recommended as first-line drug in the management of hypertensive subjects with NIDDM.

National surveillance of antimicrobial resistance in Neisseria gonorrhoeae. The Gonococcal Isolate Surveillance Project.

The Gonococcal Isolate Surveillance Project is a national sentinel surveillance system to estimate levels and monitor trends of antimicrobial resistance in prospectively collected isolates of Neisseria gonorrhoeae. Of 6204 isolates evaluated from 21 clinic sites between September 1987 and December 1988, 21% met at least one of the surveillance criteria for resistance to penicillin, tetracycline, cefoxitin, or spectinomycin; 2.2% were penicillinase-producing N gonorrhoeae; 1.0% had high-level plasmid-mediated tetracycline resistance; and 16.8% of the isolates without plasmid-mediated resistance had chromosomally mediated resistance (defined as a minimum inhibitory concentration greater than or equal to 2 micrograms/mL) to penicillin, tetracycline, or cefoxitin. Three isolates were resistant to spectinomycin. All isolates were susceptible to ceftriaxone. Resistant isolates were identified from all participating centers. Patient demographic and behavioral characteristics were not predictive of infections caused by resistant organisms. These results demonstrate the wide distribution of antimicrobial-resistant N gonorrhoeae and support recent changes in Centers for Disease Control therapy recommendations for gonococcal infections that no longer recommend tetracycline and penicillin as first-line therapies.

[Long-term results of percutaneous transluminal angioplasty of the iliac arteries].

A well-mastered technique will cause percutaneous transluminal angioplasty of iliac arteries to achieve long-term results comparable to those obtained surgically. In isolated iliac stenosis, a 95% good result rate is attained (81% cured, 14% improved). More complex cases of iliac stenosis yield 90% good results (72% cure), with a mean Doppler ankle/arm pressure index gain of 0.5 point in a series including 673 patients at 5 years follow-up. Only the presence of combined distal femoral lesions may cause the good result score to drop to 85%, including merely 35% cure. General complications are practically lacking and local complications are minimal, which incites one to propose this technique as a first-line treatment of iliac stenosis whenever distal blood circulation is maintained.

A long-term study of atenolol and doxazosin in mild and moderate hypertension.

The efficacy and tolerability of doxazosin and atenolol in the management of mild and moderate hypertension were compared in a multicentre, parallel study, the first year of which was randomized and double-blind. Patients who completed this first year were invited to enter a two-year extension phase; the results after the first year are presented. A total of 228 patients entered the double-blind phase (118 received atenolol). A reduction in dose was required by 4% in each group; eight patients on doxazosin and 11 on atenolol were withdrawn due to adverse effects. Ninety-three of the 100 doxazosin patients and 88 of the 104 atenolol patients who completed the double-blind phase agreed to participate in the open extension study. At 24 months, the mean dose of doxazosin was 5.2 mg/day, and of atenolol 66.7 mg/day. From baseline levels of BP of 158/104 mmHg in the doxazosin group and 161/103 mmHg in the atenolol group, average reductions at 24 months were -16/-14 and -19/-15 mmHg respectively. Neither drug had a significant effect on total cholesterol levels. At all four points of measurement over the two years, doxazosin decreased blood triglyceride levels and increased high density lipoprotein (HDL) cholesterol and the HDL: total cholesterol ratio. Atenolol had the opposite effect on each of these lipid values with the differences between the treatment groups being significant. Doxazosin was well tolerated and was shown to be effective as monotherapy in mild and moderate hypertension. Its effect on blood lipids was potentially favourable, and it should therefore be regarded as an alternative first-line drug in hypertensive patients.

"Poor prognosis" metastatic gestational trophoblastic disease: the prognostic significance of the scoring system in predicting chemotherapy failures.

Twenty-eight patients with "poor prognosis" metastatic gestational trophoblastic disease were treated during a 17-year period. The primary treatment was combination chemotherapy with methotrexate, actinomycin D, and chlorambucil (MAC). Patients who failed to respond to this regimen were treated secondarily with other combinations. Adjuvant surgery and radiotherapy were used in selected cases. The overall remission rate was 89% (25 of 28): 71% for first-line treatment with MAC (20 of 28) and 62% for second-line treatment (five of eight). The response rate to MAC correlated well with the patient's score (modified World Health Organization [WHO] scoring system--1983). Seventeen patients treated with MAC had scores less than 12, and all of them achieved remission. Of 11 patients having scores of 12 or more, only three achieved remission with MAC (27%). Of the eight who did not, five achieved remission with other combinations (62%) and three died. No patient died because of chemotherapy toxicity. The WHO scoring system is a good index to select high-risk patients who need primary chemotherapy more aggressive than MAC.

Comparison of cholesterol-lowering regimens.

Drug therapy should be reserved for patients with marked total cholesterol elevation not amenable to dietary measures. While current guidelines suggest that bile acid sequestrants, such as cholestyramine and colestipol, are first-line drugs for the treatment of hypercholesterolemia, recent studies suggest that lovastatin is a safe, more potent alternative. Gemfibrozil reduces the serum triglyceride level and raises the high-density lipoprotein (HDL) cholesterol level, but has only a moderate effect on the serum cholesterol level. Nicotinic acid lowers serum low-density lipoprotein (LDL) cholesterol and triglyceride levels and raises serum HDL levels, but its use is limited because of troublesome side effects, notably a flushing reaction. Probucol lowers both serum LDL and HDL levels and is a second-line agent for the treatment of hypercholesterolemia.

[Diagnostic approach of pleural effusion in children. Report of 59 cases].

The retrospective analysis of 59 pediatric cases of pleural effusion showed that infectious agents account for 80% of cases. Thoracentesis proved to be the first-line diagnostic tool. Pleural biopsy was diagnostic in four tuberculous and two malignant pleural effusions. The literature data shows that pleural fluid total protein, lactate deshydrogenase, glucose, pH, white blood cell count and differential should be obtained in all patients. Because of the high incidence of infection, microbiologic studies are also indicated in children. These studies are of great value in distinguishing transudates from exsudates and in deciding on pleural drainage.

Hairy cell leukemia. Current management.

The long-term outlook for patients with HCL has brightened over the last 5 years with the development of two highly effective systemic therapies, pentostatin and alpha-interferon. Pentostatin can induce complete responses in over 75 per cent of patients and may offer cure in this disease. Splenectomy continues to have a role as first-line therapy in selected patients in whom it may offer a median remission duration of over 5 years. Alpha-interferon is the treatment of choice for patients requiring initial systemic therapy and can be used intermittently to re-induce remission in patients with disease progression off therapy. Outside of clinical trials pentostatin should be utilized only in appropriately selected patients refractory to interferon therapy.

Overview of medical therapy of peptic ulcer disease.

Medical management of peptic ulcer disease continues to evolve with the recent introduction of new H2-receptor antagonists, prostaglandin analogs, and a proton pump inhibitor, and clarification of the relationship between suppression of gastric acidity and ulcer healing. Nizatidine and roxatidine acetate, the new H2 blockers, are safe and effective but do not appear to have new properties of clinical importance. The modes of action of omeprazole and the prostaglandins have been clarified. Omeprazole is a prodrug that is protonated and secured in the secretary canaliculus of the parietal cell where the active derivative covalently binds sulfhydryl groups of H+/K(+)-ATPase, thereby irreversibly and profoundly blocking acid secretion. Prostaglandins bind a receptor on the basolateral membrane of the parietal cell, releasing a protein that inhibits cyclic AMP, the second messenger of histamine-stimulated acid secretion. The ulcer-healing properties of prostaglandins can be attributed largely if not entirely to their inhibition of acid secretion. Antacids, on the other hand, may heal ulcers by effects other than acid neutralization, as the low-dose regimens that heal ulcers only weakly neutralize acid. The way in which sucralfate and colloidal bismuth heal ulcers remains unclear; they may do so through multiple effects including, in the case of bismuth, eradication of C. pylori. H2-receptor antagonists continue as first-line treatment for acute DU and GU and the prevention of recurrence. The antacid and sucralfate regimens are less convenient but safe and effective. Misoprostol has a disadvantageous safety profile relative to available agents but is effective in preventing NSAID-induced gastric ulcers. The efficacy of omeprazole in acid-peptic disease is established but the way in which it should be used is still unclear because of long-term safety concerns.

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.

Buccal administration of fenoterol aerosol in young children with asthma.

A new technique for the administration of a bronchodilator aerosol, fenoterol, in young children with asthma is described. Rapid and effective bronchodilatation can be obtained in many patients simply by directing the jet of the bronchodilator aerosol onto the buccal mucosa. This method will frequently obviate the need for painful or potentially dangerous injections of adrenaline or aminophylline as a first-line treatment in children with acute attacks of asthma.
