Similar efficacy following four weeks treatment of asthmatics with formoterol 12 micrograms b.d. delivered by two different dry powder inhalers: differences in inhaler handling.

This randomised, multicentre, parallel-group study compared the clinical efficacy and ease of handling of two dry powder inhalers delivering the long-acting beta 2-agonist formoterol. After run-in, 200 asthmatics on treatment with inhaled corticosteroids and still presenting with suboptimal asthma control were randomised to receive 12 micrograms formoterol twice daily via either the Aerolizer inhaler (Foradil Aerolizer) or the Turbuhaler inhaler (Oxis Turbuhaler) for four weeks. Study variables included the mean morning pre-medication peak expiratory flow (PEF) during the last seven days of treatment and the correct inhaler handling according to inhaler-specific checklists. The mean difference in the effect on morning pre-medication PEF was 13.86 l/min in favour of formoterol via the Aerolizer inhaler (90% confidence interval 2.50, 25.21) in the intent-to-treat population. Eighty-six per cent of the patients under treatment with formoterol via the Turbuhaler inhaler performed correctly all the essential inhalation manoeuvres, whereas 98% of those on the Aerolizer inhaler did so. These results strongly suggest similar clinical efficacy with twice daily treatment of formoterol 12 micrograms metered dose delivered either by the Aerolizer, or the Turbuhaler device. They also suggest that handling the Aerolizer is easier than that of the Turbuhaler.

Diet and disease--the Israeli paradox: possible dangers of a high omega-6 polyunsaturated fatty acid diet.

Israel has one of the highest dietary polyunsaturated/saturated fat ratios in the world; the consumption of omega-6 polyunsaturated fatty acids (PUFA) is about 8% higher than in the USA, and 10-12% higher than in most European countries. In fact, Israeli Jews may be regarded as a population-based dietary experiment of the effect of a high omega-6 PUFA diet, a diet that until recently was widely recommended. Despite such national habits, there is paradoxically a high prevalence of cardiovascular diseases, hypertension, non-insulin-dependent diabetes mellitus and obesity-all diseases that are associated with hyperinsulinemia (HI) and insulin resistance (IR), and grouped together as the insulin resistance syndrome or syndrome X. There is also an increased cancer incidence and mortality rate, especially in women, compared with western countries. Studies suggest that high omega-6 linoleic acid consumption might aggravate HI and IR, in addition to being a substrate for lipid peroxidation and free radical formation. Thus, rather than being beneficial, high omega-6 PUFA diets may have some long-term side effects, within the cluster of hyperinsulinemia, atherosclerosis and tumorigenesis.

[Intracavernous auto-injection of prostaglandin E1 for diagnosis and treatment of erectile dysfunction].

34 impotent patients were offered auto-injection therapy and all except 2 began treatment. Prostaglandin E1 (PGE) was used regularly for a mean of 8.6 months (range 1-17). The onset of erection was 5-30 min (mean 11.4) after injection and it lasted at least 30 min (mean 106.2 min). An erection of more than 6 hrs was observed in only 2 patients. There have been no instances of cavernous fibrosis, chemical priapism or systemic reactions. The most common adverse effect was penile pain after injection. It was mild to moderate in 4 patients (11.7%), and in only 1 was it severe enough to require stopping treatment. Overall, intracavernous injection of PGE appears to be safe, effective treatment for impotence without side-effects other than pain after injection in a few.

Insulin and glucose status, tissue and plasma lipids in patients with tumours of the ovary or endometrium: possible dietary implications.

The relationship between tumour growth, insulin status, blood lipids and adipose linoleic acid (LA, reflecting long-term LA intake) was studied in 19 Jewish women suffering from early and advanced stages (ES and AS) of ovarian and endometrial tumours. Blood insulin in patients with ES tumours was four times higher than the control value in cancer-free subjects, but fell to normal levels at AS and after ES surgery (PES). Tumours and abdominal adipose tissue (AAT) had 4-6 and 1.4-1.7 times as much insulin as non-cancerous control organs. Serum total cholesterol (CHOL) and LDL-cholesterol were high at ES, dropped below normal at AS, but normalised at PES, while HDL-cholesterol increased after ES surgery. Linoleic acid in subcutaneous adipose tissue (SAT) was high in controls (26.4 + 1.5% of total fatty acids), but lower in cancer patients (20.5 + 3.7%, P < 0.05), while palmitic acid showed the opposite change. The results suggest mobilisation of glucose, cholesterol and linoleic acid for the supply of energy and structural lipids to rapidly multiplying tumour cells and possibly for prostaglandin synthesis. They also raise the question of whether the high linoleic acid intake by the Jewish population in Israel predisposes individuals to tumour development.

[Benefits of perioperative hemodynamic monitoring in coronary patients].

During 1987-1991, 78 coronary patients were admitted to the intensive care unit (ICU) for noncardiac surgery. 40 were under invasive hemodynamic monitoring and treatment before operation (group A) and 38 were only admitted to the ICU postoperatively, since ICU beds were not available before surgery (group B). The overall incidence of the perioperative complications, ischemic heart, myocardial infarction and cardiac arrhythmias was significantly higher in group B than in group A (p < 0.01). 5% of group A and 11% of group B died in the ICU postoperatively. These data indicate the importance of preoperative hemodynamic and cardiac monitoring and treatment in coronary patients.

Bronchiolitis obliterans--current concepts.

We review current concepts about the clinical manifestations, diagnosis and treatment of patients with bronchiolitis obliterans (BO) with emphasis on clinical/pathological correlations and recent developments. BO is a relatively rare disease, but its incidence is probably higher than generally believed and is continuously rising, partly because of better recognition, but also because of increased exposure to industrial fumes, and its occurrence in lung transplantation. BO is characterized histologically by varying degrees of obliteration of the lumen of the respiratory bronchioles by organizing connective tissue often extending into the alveoli ('proliferative' BO with organizing pneumonia--BOOP) or by more extensive fibrosis and scarring of the more proximal, conductive bronchioles ('constrictive' BO). Diverse clinical conditions have been associated with the development of BO, notably viral and mycoplasma infection, toxic fume exposure and immune reactions in the setting of a collagen vascular disease, drug reaction or organ transplantation. The clinical course and features of BO may vary considerably according to the aetiology, histological pattern and stage of the disease. The most common presentation is that of a progressive dry cough and dyspnea, associated with diffuse patchy interstitial lung infiltrates on chest X-ray. In the more advanced cases, lung function tests show either restrictive or obstructive defects, depending on the extent of alveolar involvement, and hypoxemia without CO2 retention. The diagnosis is often possible on clinical grounds, however, in a seriously ill patient uncertainty should be resolved by tissue diagnosis, preferably by open lung biopsy. Treatment is based on symptomatic therapy. The use of corticosteroids is controversial, but common. Patients with BOOP are exceptional, in that there may be no underlying condition ('idiopathic' BOOP or cryptogenic organizing pneumonia--COP), a restrictive ventilatory defect is usual and the response to corticosteroids often remarkable.

[Primary tuberculosis of the glans penis].

Primary tuberculosis of the glans penis is extremely rare. We report a case in a 70-year-old man who presented with a deep ulceration of the ventral surface of the glans which mimicked malignancy. The diagnosis of tuberculosis was confirmed by biopsy, culture, and response to antituberculous chemotherapy. There was no coexisting tuberculous infection elsewhere.

Early pregnancy termination: an improved technique for 'menstrual regulation' with ultrasound assistance.

We performed aspiration of early pregnancy on 100 women requesting termination, using a low caliber angled catheter under sonographic guidance, without analgesia or anesthesia. The sonographic inclusion criteria for the study were: (1) mean gestational sac diameter less than 30 mm, or (2) crown rump length less than 10 mm when an embryo was visualized. The uterine content was successfully evacuated in all cases and none needed an additional curettage. Two women developed mild endometritis which responded to antibiotic therapy. This refinement of this 'menstrual regulation' technique seems to be safer when compared with the reported results of the original technique.

Simultaneous bilateral spontaneous pneumothorax: case report.

A 22-year-old previously healthy male was admitted to the emergency department for chest pain and dyspnea of 1-day's duration. He had a history of heavy smoking. The patient was cyanotic, agitated, and severely dyspneic. Lung auscultation revealed severe diffuse bronchospasm and equally diminished breath sounds on both sides. Nasotracheal intubation and mechanical ventilation were performed shortly after admission due to acute respiratory failure. Simultaneous bilateral spontaneous pneumothorax was diagnosed from the chest x-ray, and chest tube drainage was immediately performed bilaterally. Computerized tomography of the chest 1 month later showed diffuse emphysematous bullae of the lungs. The case presented here should increase physicians' awareness of this rare form of spontaneous pneumothorax and its diverse manifestations.
