Foreign body aspiration in children. The diagnostic value of signs,symptoms and pre-operative examination

One hundred and fifteen patients, between 6 months and 12 years of age, had bronchoscopy on suspicion of foreign body aspiration. The histories of these patients were studied to examine the diagnostic value of signs, symptoms and examinations, and to determine the time that passed between aspiration and removal of the foreign body. The sensitivity of the symptoms choking and coughing was fairly high (81 and 78%), but the specificity was poor. The sensitivity of a chest radiograph was 82%, the specificity 44%. The sensitivity of radiographs on inspiration and expiration was 80%, the specificity 55%. The patients had been referred with the initial diagnosis foreign body aspiration (80), pneumonia (34), or subglottic laryngitis (1). In 85 patients a foreign body was identified and extracted. The other 30 patients had respiratory tract infections. The initial diagnosis of foreign body aspiration was correct in 61 out of 85 patients. In these cases, the period between aspiration and extraction of the foreign body was a mean 6 days, compared with 55 days, if the initial diagnosis was pneumonia or sub-glottic laryngitis. We conclude that the diagnosis of foreign body aspiration is too often missed, and that, apart from bronchoscopy, diagnostic tools are of little value.     

Moclobemide and specific serotonin re-uptake inhibitor combination treatment of resistant anxiety and depressive disorders

This retrospective study was undertaken with the objective of determining how effective and safe moclobemide, a specific and reversible inhibitor of monoamine oxidase-A (RIMA), is when used in combination with specific serotonin re-uptake inhibitors (SSRIs), in a clinical setting. A thorough chart review was done of all patients with affective and anxiety disorders seen at our centre who received combination treatment with moclobemide and an SSRI. Combination moclobemide-SSRI treatment demonstrated good efficacy in treating treatment-resistant patients. The combination treatment was well tolerated with very few drug interactions. Dosages should be started low, titrated slowly and carefully, and patients should be monitored closely.     

Moclobemide versus fluoxetine for a major depressive episode

The efficacy and tolerability of moclobemide (300–600 mg daily) and fluoxetine (20–40 mg daily) were compared in a 6-week, double-blind study of 65 inpatients and 34 outpatients suffering from major depressive episodes (DSM III-R). No statistically significant differences between the two treatment groups were noted regarding efficacy (HDRS, CGI) or safety (adverse events, laboratory examination, vital signs). Moclobemide (300–600 mg daily) and fluoxetine (20–40 mg daily) would thus appear to be comparable both in antidepressant efficacy and tolerability. Doubling the low dosage in non-responders after 3 weeks resulted in a statistically significant improvement of CGI in the moclobemide group by comparison with the fluoxetine group at study end, suggesting that 600 mg moclobemide/day can still improve the patient's condition, while 40 mg fluoxetine/day does not. Sexual dysfunction was reported in two patients taking fluoxetine.

曲米帕明与米帕明治疗抑郁症的对比

曲米帕明（男性２０例，女性１２例；年龄３６±５１２ａ）和米帕明（男性１９例，女性１３例；年龄３８±１１ａ）治疗６４例抑郁症。开始剂量均为５０ｍｇ／ｄ，１ｗｋ内加至１５０－３００ｍｇ／ｄ，共４ｗｋ。用ＨＡＭＤ量表评定。结果显示２组抗抑郁疗效相仿。ＨＡＭＤ总分及各因子分的减分２组间无显著差异（Ｐ＞０．０５）。２组的主要不良反应为抗胆碱能症状，对心脏的影响曲米帕明似较米帕明为轻。     

Health-related quality of life under six months' treatment of migraine—an open clinic-based longitudinal study

Health-related quality of life (HQL) assessment in the clinical setting have distinguished subjective perceptions (e.g. well-being), signssymptoms of the disease, and functional capacity as three major components. The impact of short-term treatment for migraine attacks on these variables was evaluated in an open prospective 6-month study at the Gothenburg Migraine Clinic. Socio-economic factors, subjective symptoms, and general well-beingquality of life were evaluated by self-administered questionnaires in 99 patients with migraine with or without aura in accordance with the classification of the International Headache Society. Short-term treatment comprising conventional therapy or subcutaneous sumatriptan reduced number of days per month with migraine and absenteeism from work, migraine-associated symptoms, but did not significantly improve general well-being between attacks. Future assessment of the patients' HQL in accordance with this approach would enable us to consider all the advantages and disadvantages of current therapies of particular interest in the field of migraine.     

Effects of occupational exposure and smoking on respiratory symptomatology and PFT in healthy panelists and COPD patients

A panel of 377 healthy adults and 920 COPD patients aged 30–65 years, is annually interviewed (ATS-NHLI health questionnaire) and performs pulmonary function test (PFT), which includes: FVC, FEVI, FEVl/FVC, PEF, FEF50 and FEF75. Baseline data analysis showed a more significant excess in respiratory symptmos (8.8% to 21.4%) and lower PFT (2.4% to 8.0%) among patients occupationally exposed to dust, than among healthy exposed panelists (-0.7% to 7.7% excess symptomatology and -0.3 to 5.8% lower PFT). Among patients a significant correlation between PFT and degree of occupational dust exposure was found. Significantly lower FEVl/FVC and excess in respiratory symptoms (with relative risks of 2.47–16.38) was present in healty smokers vs. non smokers as compared with COPD patients.Corresponding author.

The treatment of diffuse lewy body disease: A pilot study

Single case studies may provide useful information and generate hypotheses for later testing in group studies. The effect of anti-Parkinsonian medication is reported in five individual cases of diffuse Lewy body disease. The problems caused by the variability in congnitive function and psychiatric symptoms in these cases are outlined together with suggested strategies for future research.
