Antihypertensive drugs and blood lipids.

Hypertension frequently coexists with hyperlipidaemia and it has been suggested that the potential benefits of blood pressure reduction may be compromised if lipid levels are not concurrently reduced. In addition, conventional first line antihypertensive drugs (thiazide diuretics and beta-blockers) produce adverse changes in blood lipids which are most apparent in the short-term but do not entirely disappear during chronic treatment. Of the alternative first-line antihypertensive agents, the calcium antagonist and ACE inhibitor drugs are lipid 'neutral' but only the alpha 1-blockers have been associated with favourable effects on the lipid profile.

[Converting enzyme inhibitors and cardiac insufficiency: current findings and perspectives].

Angiotensin-converting enzyme inhibitors are mixed vasodilators with a prolonged sustained effect in chronic heart failure. They also act on the reactivity of peripheral circulation, on ventricular remodelling after myocardial infarction, on myocardial hypertrophy in arterial hypertension and on ventricular hyperexcitability. They alleviate the symptoms of symptomatic heart failure, and they constitute the only treatment that has been able to improve the survival of patients with the most severe heart failure. Several studies are in progress to determine whether these drugs should be used as first-line therapy.

Moricizine: a new class I antiarrhythmic.

The chemistry, pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage of the Class I antiarrhythmic agent moricizine hydrochloride are reviewed. Moricizine is chemically similar to the phenothiazines but does not appear to block dopaminergic receptors. Its major electrophysiologic actions are a concentration-dependent decrease in maximum rate of phase 0 depolarization; increased rates of phase 2 and 3 repolarization, decreased action potential duration, and decreased effective refractory period. Moricizine causes a dose-related prolongation of the PR interval and of AV nodal, infranodal, and intraventricular conduction times but has little effect on ventricular repolarization. The antiarrhythmic and electrophysiologic effects are not correlated with plasma concentrations of the drug or its metabolites. Moricizine reduces the occurrence of ventricular premature contractions (VPCs), couplets, and nonsustained ventricular tachycardia. It appears to suppress symptomatic nonsustained ventricular tachycardia, sustained ventricular tachycardia, and ventricular fibrillation or flutter. Moricizine appears to be as effective as quinidine and more effective than disopyramide, propranolol, and imipramine but less effective than flecainide and encainide at reducing VPCs. Moricizine continues to be evaluated in the Cardiac Arrhythmia Suppression Trial, which was designed to assess the long-term benefit of arrhythmia suppression in patients with left ventricular dysfunction after myocardial infarction. Moricizine seems to be better tolerated than quinidine, disopyramide, and imipramine and to have less proarrhythmic potential than flecainide or encainide. Noncardiac adverse effects include dizziness, nausea, and headache. Cimetidine appears to decrease moricizine clearance, and decreased theophylline clearance has been reported in subjects given moricizine. The usual adult dosage of moricizine hydrochloride is 600-900 mg/day given in three divided doses; an every-12-hour regimen may be used in some patients. Because of the risk of proarrhythmic effects, indications are limited to treatment of documented life-threatening arrhythmias. Moricizine will compete with other agents as first-line therapy for life-threatening arrhythmias.

Fetal echocardiography in Manitoba: a regional perspective.

In order to investigate the impact of detailed fetal echocardiography on perinatal care at a tertiary health care centre, the records of all 29 cases referred for fetal echocardiography during the years 1987-88 were reviewed. All patients had risk factors for offspring with congenital heart disease. A family history of congenital heart disease led to fetal echocardiography in about two-thirds of the cases, while the remainder were referred on the basis of abnormal cardiac screening examinations during fetal assessment. Forty examinations were performed on patients at gestational ages of 16 to 37 weeks. Detailed fetal echocardiography did not alter the perceived severity of major structural cardiac defects previously identified by an experienced fetal assessment unit and did not change or influence intrapartum care. The value of fetal echocardiography in the diagnosis and treatment of fetal tachyarrhythmias was confirmed. Also, fetal echocardiography provided reassurance of cardiac normality in cases with familial and maternal risk factors for congenital heart disease. Fetal echocardiography appears to be an inappropriate screening tool in view of its limited availability and focus. Comprehensive fetal assessment with four chamber cardiac imaging is the appropriate first-line screening test for patients with risk factors for offspring with congenital heart disease.

Treatment of herniated lumbar disc by percutaneous nucleotomy with aspiration. Preliminary results in 70 cases.

Seventy patients suffering from lumbar pain with sciatica, radiculalgia or lumbodynia were reviewed at least 3 months after automated percutaneous nucleotomy (Nucleotome). There were 26 women and 44 men, aged from 19 to 72 years. Results were highly satisfactory in 39 patients (56.5%). Among these, 10 had lumbar pain of discal origin, 15 had pure radiculalgia and 14 had lumbar pain and radiculalgia. Incomplete improvement requiring medical treatment was obtained in 11 patients (15.5%). The procedure was unsuccessful in 20 patients (28.5%) with persistence or worsening of the initial symptoms; 5 of them subsequently underwent chemonucleolysis with 4 good medium-term results and 1 failure. These preliminary results show that percutaneous nucleotomy seems to be effective in lumbar pain of discal origin, with a 66.5% success rate. In patients with pure radiculalgia or lumbar pain cum radiculalgia the results are less impressive, with a success rate of about 50%. However, this well-tolerated technique may be used as first-line treatment of herniated discs when the discs are small, subligamentous and non migrated.

[Clinical effectiveness of delayed-action theophylline preparations].

Clinical efficiency of course treatment has been assessed for 5 long-acting drugs of theophylline series: retaphylline (Finland), theo-dur (Sweden), durophylline (Yugoslavia), theopek and theobilong (USSR). The drugs were tested in 139 patients with chronic++ bronchial obstruction. It was established that first-line therapy with theophylline should be started with low doses (400 mg/day) and last for 3 days to define individual sensitivity to theophylline drugs followed by increasing doses. On day 7 serum theophylline levels were to be measured for control and dose correction. In cross administration and adequate doses the drugs activity was similar. For patients suffering from nocturnal asthma attacks it was an atypical doze regimen implying administration of two-thirds of the day, dose in the evening that produced the highest effect. The incidence and severity of CNS, cardiovascular and gastrointestinal side effects varied with the dose blood concentration and individual sensitivity to theophylline.

Amyloid tumour resected by laser therapy.

We report a patient presenting with dyspnoea, cough and fever with a middle lobe atelectasis. Amyloid deposits in the bronchial wall caused almost complete obstruction of the middle lobe bronchus. The patient was treated with neodymium yttrium aluminium garnet (NdYAG) laser photoresection resulting in complete clearance of the middle lobe bronchus. Laser therapy has to be considered as first-line therapy for patients with endobronchial amyloidosis.

[Treatment of invasive epithelioma of the uterine cervix: the experience at the Institut Gustave-Roussy].

The therapeutic protocole used at the Gustave Roussy Institute for invasive epithelioma of the uterine cervix rests, for limited forms (T1B-T2 proximal), on combined radiology and surgery. This include the recently introduced supraradical lymphadenectomy extended to the lumboarotic lymph nodes, first-line surgery in young women to preserve the ovarian function and postoperative chemotherapy for extra-pelvic N+ forms. In extensive forms (distal T2 and T3), the treatment of choice still is radiotherapy with external irradiation associated with curietherapy. T3 forms with urinary tract involvement now benefit from interventional radiology techniques. The basic treatment of T4 forms involving the bladder and/or rectum remains radiotherapy, but wide surgical resection (exenteration) is still indicated in some cases. The treatment of particular forms (post-hysterectomy cervix, uterine prolapse, pregnancy) relies on techniques that are suitable for each individual situation.

Definition of refractoriness against conventional chemotherapy in acute myeloid leukemia: a proposal based on the results of retreatment by thioguanine, cytosine arabinoside, and daunorubicin (TAD 9) in 150 patients with relapse after standardized first line therapy.

Response to salvage therapy at first and second relapse was analyzed in 150 patients with acute myeloid leukemia (AML) to improve the characterization of relapsed AML and to deduce from this analysis a proposal for the definition of refractoriness against conventional therapy. Salvage treatment consisted of a repetition of the TAD 9 regimen which was already applied as induction protocol at initial diagnosis. All patients were recruited from the multicenter 1982 trial of the German AML Cooperative Group and had thus received a standardized first line treatment. Response at first relapse was significantly related to the duration of the first remission. From 38 patients relapsing within 6 months after successful induction therapy, only 11 (28%) achieved a second complete remission as compared to 58 of 98 (59%) cases with later occurring relapses (p less than 0.01). This difference was due to a significantly higher incidence of persistent leukemia in the former group and not biased by differences in early death rates. No other variable was found predictive for the response to salvage treatment including age, WBC, serum LDH, morphologic subtype, presence or absence of DNA aneuploidy as detected by flow cytometry or maintenance chemotherapy. A low remission rate of 28% was also obtained in the 14 patients at second relapse. These data indicate that patients with a duration of their first remission of more than 6 months cannot be considered as being refractory against standard chemotherapy while patients with early relapses and second recurrences have a response rate of less than 30% due to refractory disease. Hence, the following criteria are proposed for the definition of refractoriness against standard chemotherapy in advanced AML: (a) nonresponse to first-line induction therapy, (b) early relapse within 6 to 12 months of first remission, (c) relapse after 6 to 12 months of first remission and failure on a reinduction attempt with established regimens, (d) second and subsequent relapses. These criteria may provide a useful rationale for the selection of the most appropriate treatment at relapse. They may also serve as eligibility criteria for clinical phase I/II studies and will facilitate interstudy comparisons.

[Can tumors of the breast larger than 3 centimeters be treated conservatively?].

Unlike small breast cancers, which are now treated conservatively by primary tumorectomy, the most important lesions (T2 and T3) as usually treated tumorectomy, the most important lesions (T2 and T3) as usually treated by mastectomy. However, in patients with these large lesions attempts may be made at conserving the breast with reliable oncological safety and good cosmetic results. Depending on clinical presentation, one or the other of two therapeutic approaches may be considered. The most common treatment is preoperative radiotherapy of 45 Gy which, in more than 50 p. 100 of the cases results in a tumoral regression that is sufficient for secondary tumorectomy to be performed. In some patients, the first-line treatment consists of wide tumoral excision as part of a reductive mammaplasty, followed by radiation.

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.
