Mivacurium chloride and late onset congenital myopathy.

We describe the successful use of the short-acting, non-depolarizing neuromuscular blocking agent, mivacurium, in a 53-yr-old female patient with late onset congenital myopathy, undergoing elective submucous resection of the inferior turbinates. She was unable to climb stairs and walking was limited to periods of 15 min because of generalized weakness, fatigue and shortness of breath. A Datex Relaxograph was used to monitor the train-of-four count. No increase in sensitivity to mivacurium was demonstrated. A dose of 12 mg (three times the recommended ED95) resulted in 88% reduction of the first of the train-of-four count (T1) compared with control (TC). Spontaneous recovery of T1/TC to 100% took 11 min 20 s from the time maximum block was first achieved. The recovery index (25-75% T1/TC) was 4 min 40 s.

Time course from first symptom to treatment in patients with non-small cell lung cancer referred for radiotherapy: a report by the CHART Steering Committee.

BACKGROUND: Only a small proportion of patients with non-small cell lung cancer (NSCLC) attending radiotherapy centres were suitable for inclusion in a randomised trial which compared continuous hyperfractionated accelerated radiotherapy (CHART) with conventional radical radiotherapy. As this was thought to be partly due to delays in the referral of patients to clinical oncologists, a prospective study was performed to determine the interval between first report of symptoms and first radiotherapy treatment in patients with NSCLC. METHODS: The time course from first symptom to treatment was determined in all patients with NSCLC attending 10 cancer centres for radiotherapy to a primary tumour in a three month period. RESULTS: Only 5% of 484 patients were suitable for the trial of radical radiotherapy. The principal causes for exclusion were poor general condition (37%), too large a tumour (27%), and extrathoracic metastases (19%). The median time from first symptom to diagnosis was 13 weeks, from first symptom to first treatment 19 weeks, and from diagnosis to first treatment five weeks. In a quarter of the patients these intervals were greater than 25,33 weeks, and nine weeks, respectively. CONCLUSION: The reason for these long intervals needs investigation since earlier diagnosis and more immediate referral for consideration of treatment might increase the number of patients with NSCLC suitable for radical radiotherapy.

Analysis of cytodiagnostic urinalysis findings in 77 patients with concurrent renal biopsies.

We investigated the value of cytodiagnostic urinalysis in detecting and scoring the severity of the four types of renal lesions (glomerular, interstitial, tubular, and vascular). Both cytodiagnostic urinalysis and concurrent renal biopsy were performed in 77 patients (47 from native kidneys and 30 from transplants) and the scoring and findings assessed in a double-blinded fashion. Evaluation of the reproducibility for the counting of renal cells showed a low intraobserver and interobserver variation. Cytodiagnostic urinalysis correlated with the renal biopsy with respect to primary lesions in 42 (89%) of the native kidney cases, and in 23 (77%) of the transplant kidney cases. The accuracy of diagnosis of glomerular lesions in both native and transplanted kidneys was 0.91, and for acute rejection in transplanted kidneys, the accuracy of diagnosis was 0.73. Severity scores showed good correlation between cytodiagnostic urinalysis and renal biopsy in both transplanted and in native kidneys and cytodiagnostic urinalysis correlated well with the increase in creatinine levels. The most important components of cytodiagnostic urinalysis for the diagnosis of glomerular lesions were dysmorphic erythrocytes and proteinuria. The specificity and sensitivity of dysmorphic erythrocytes for a glomerular lesion were 0.89 and 0.88, respectively. In cases with biopsy-proven glomerular lesions, more severe changes were found by cytodiagnostic urinalysis when the biopsy showed proliferative lesions in the glomeruli than when normal glomeruli were found by light microscopy. Cytodiagnostic urinalysis has the advantage over renal biopsy that it can be repeated as often as necessary and thus allows observation of the development or regression of the renal lesion over time. We conclude that cytodiagnostic urinalysis is well correlated with the renal biopsy and that it provides valuable and quantitative information regarding the disease process in the kidney.

Meta-analysis of the role of platinum compounds in advanced ovarian carcinoma. The Advanced Ovarian Cancer Trialists Group.

This paper presents a systematic overview or meta-analysis of 54 randomized clinical trials testing a variety of chemotherapeutic approaches in advanced ovarian carcinoma. Prolonged follow-up data are available for most patients and individual patient data were made available for all patients; analysis was made on the basis of "intention to treat." Our report concentrates on two comparisons: (1) platinum alone versus platinum in combination, which appears to show a long-term survival advantage for the combination (however, the platinum dose in the single-agent arm was relatively low); and (2) carboplatin versus cisplatin, which shows no obvious survival differences. It is striking that no single study to date has been large enough to detect the modest survival differences expected from current therapy. Consequently, a series of international studies have been initiated. The International Collaborative Ovarian Neoplasm (ICON) group will examine the role of adjuvant chemotherapy in early ovarian cancer (ICON 1) and will compare carboplatin with cisplatin, doxorubicin, and cyclophosphamide in more advanced disease (ICON 2).

Respiratory consultations in asthmatic compared with non-asthmatic children in general practice.

In a retrospective study we found that before a diagnosis of asthma had been made children with asthma had consulted their general practitioner more often with respiratory symptoms than children who were non-asthmatic under the age of four. In the second, third, and fourth years the number of consultations differed significantly between the two groups. Asthma should be suspected in any child who presents often with respiratory symptoms. This should lead to earlier diagnosis in most cases.
