[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.

Epidemiology of hypertension among Chinese in Taiwan.

A series of population surveys in Taiwan have found that hypertension was present in 14.1% in 1976 and in 14.8% in 1984 in those aged above 18, and in 33.4% in 1976 and in 31.4% in 1987 in the elderly. In 1976, 4.5% of hypertensives aged 18 and over had good blood pressure control and in 1982 this figure was still only 4.9%. The outcome among 3037 untreated hypertensives out of a general population of 17,000 in southern Taiwan showed that 49.9% of those hypertensives died in the 22-year follow-up period. The annual death rate from stroke was 5.9/1000/year in untreated hypertensives but only 0.8/1000/year in normotensives. Compliance rate for treatment of hypertension in Taiwan showed that 81.6% of patients had good compliance under a free-of-charge programme with 86.1% of them having their blood pressure under control. In a comparison of the efficacy of antihypertensive drugs as first-line, propranolol (40.8%) proved to be more efficacious than trichlormethiazide (33.2%) in Taiwanese hypertensives. The difference however was not statistically significant.

[Surgical treatment of portal hypertension].

The surgical treatment, by means of shunts or disconnections, of ruptured oesophageal varices in portal hypertension is always indicated but not always on the forefront. However, it remains the first-line treatment in segmental portal hypertension and in Budd-Chiari syndrome. It is on a par with the non-surgical treatments in case of prehepatic block but ranks second in case of pre- and intrasinusoid blocks. In all the hepatic diseases with threatening hepatocellular deficiency, liver transplantation is the most spectacular of current and future achievements.

Survey of physician practices in managing patients with chronic ventricular arrhythmias.

To better understand how physicians manage patients with chronic ventricular arrhythmias, questionnaires were mailed in July, 1989, to 680 internists, family physicians and cardiologists in West Virginia. Responses were returned by 35 per cent; those from 33 physicians who seldom prescribed drugs to treat arrhythmias were excluded from analysis. Quinidine and procainamide were the preferred first-line antiarrhythmics for 53.3 per cent and 24.3 per cent of physicians, respectively. Control of symptoms was listed as the usual indication for therapy by 32.2 per cent, and improvement in prognosis by 20.1 per cent. Physicians perceived a high prognostic benefit to antiarrhythmic treatment in patients with sustained ventricular tachycardia or history of cardiac arrest, and a generally low prognostic benefit in those with mitral valve prolapse. Opinion was divided on the prognostic benefit in other patient groups including those with frequent ventricular premature beats following myocardial infarction. These results help quantify current physician practices in managing patients with chronic ventricular arrhythmias.

Antimicrobial susceptibility patterns of Haemophilus isolates from children in eleven developing nations. BOSTID Haemophilus Susceptibility Study Group.

The antimicrobial susceptibilities of 426 isolates of Haemophilus species, which were collected as part of a worldwide study of the etiology of acute respiratory disease in children in selected developing countries, were determined. Eleven antibiotics were tested using the recently described Haemophilus Test Medium. There was a low prevalence of antibiotic resistance; 6% of strains were resistant to ampicillin, and 1.6% were resistant to chloramphenicol. Strains resistant to both ampicillin and chloramphenicol were recovered only from Thailand. Susceptibility to penicillin G was also determined; the minimum inhibitory concentrations for penicillin and ampicillin were concordant within one 2-fold dilution in 97% of the isolates. Thus, Haemophilus isolates were as susceptible to penicillin G as they were to ampicillin, and penicillin resistance was infrequent overall. These data provide support for the current protocols for the management of acute respiratory infections in children in developing countries, in which penicillin G is a first-line agent.

[Empirical treatment of febrile episodes in granulocytopenic patients with a combination of piperacillin and ofloxacin. Preliminary study].

We evaluated the efficacy and toxicity of piperacillin-ofloxacin as an empiric treatment of fever in patients with neutropenia. 24 febrile episodes occurring in 21 patients (mean neutropenia: 204/mm3) were treated. The neutropenia was due to an hematologic malignancy in 6 cases and to chemotherapy in 15 cases. Fever was related to septicemia in 4 cases, urinary tract infection in 1 case, other infectious sites without microbiological documentation in 11 cases, and was of unknown origin in 8 cases. Empirical therapy was started within 24 hours of the occurrence of fever greater than 38.5 degrees C with the combination of intravenous piperacillin (12 g/day in 3 divided doses) and oral ofloxacin (400 mg/day in 2 doses). The overall response rate was 86% (19/22) of evaluable cases, with an immediate success rate (apyrexia within 48 hours) of 46%. Of the 3 failures, one was bacteriologically documented and was due to a multiply resistant strain of Staphylococcus haemolyticus (to which both piperacillin and ofloxacin were resistant). The therapy was clinically well tolerated in all except 3 patients, in whom intolerance to intravenous piperacillin was observed, leading to discontinuation of the drug in 2 cases. More extensive and comparative trials should better determine the place of this piperacillin-ofloxacin combination as first-line treatment of febrile episodes in patients with neutropenia.

[A case of stage III ovarian carcinoma successfully treated with oral etoposide].

A 49-year-old woman with stage III ovarian cancer (undifferentiated adenocarcinoma), who refused combination chemotherapy for postoperative residual tumor, were successfully treated with daily oral etoposide in the outpatient clinic. The etoposide (50 mg/day) was first given orally and then a dose of etoposide was decreased to 25 mg/day because of alopecia and gastrointestinal toxicity. After seven months of treatment, the complete remission was confirmed by the second look laparotomy, and cytology of peritoneal surface revealed no signs of adenocarcinoma. This case suggests that daily oral etoposide therapy might be the alternative as a first-line and second-line chemotherapy of ovarian cancer in the outpatient clinic.

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.

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.
