摘要:
A random sample of subjects over 65 years of age who had replied to a postal questionnaire on respiratory symptoms was asked to attend for lung function studies and, if fit, an inhaled methacholine bronchial challenge. Of 283 subjects, 180 (63.6%) agreed to attend. Most (98%) subjects performed reproducible spirometry, with no evidence of fatigue on repeated testing. However, 20 subjects were found to be unsuitable for challenge (forced expiratory volume in 1 s, (FEV1) < 1 litre or unable to perform spirometry reproducibly). The dose of methacholine producing a 20% fall in FEV1 was termed the PD20. A positive challenge with PD20 < 6.13 μmol methacholine was found in 69 of 160 (43%) subjects studied, with highly reactive airways (PD20 < 1.0 μmol methacholine) in 19 of 160 (12%). Bronchial hyperreactivity, which is closely associated with clinical asthma, was found to be far more common amongst the elderly than previously recognised. Low initial FEV1 (1-1.5 litres) predisposed to both a positive challenge (p < 0.01) and also to highly reactive airways (p < 0.01), generally associated with respiratory symptoms. Subjects with low (1-1.5 litres) baseline FEV1 were five times more likely to have highly reactive airways than those with FEV1 1.5 litres, confirming a relationship between baseline airway calibre and bronchial reactivity. Early detection of subjects with low FEV1, who are therefore more likely to have increased airway reactivity, may help to reduce respiratory morbidity in the elderly with considerable benefit both to patients and to the Health Servic

摘要:
During the past decade, controversy has raged about the necessity of renal biopsy for the management of the idiopathic nephrotic syndrome. The debate has centered on whether a precise diagnosis is imperative for steroid treatment or whether such therapy can be given blindly. The above question has not been addressed in the elderly. In this retrospective study 30 patients aged > 60 years, all of whom underwent a renal biopsy for an unexplained nephrotic syndrome, were categorized according to histological findings and clinical evolution of their disease. The spectrum of histology was diverse, the most common renal lesion diagnosed being membranous glomerulopathy (MGN) (23%). At variance with other works is the relatively high incidence of membranoproliferative glo-merulonephritis (MPGN) (20%) found by us. Minimal change disease (MCD) and amyloidosis were encountered in 5 (17%) and 4 patients (13%), respectively. Specific therapy (steroids) was administered in 11 patients. No benefit of steroid treatment was shown in patients with either MGN or MPGN. The only lesion which responded to steroids was MCD (3 complete remissions, 1 partial). Only one biopsy was complicated by a clinically significant perirenal hematoma requiring blood transfusion. No surgical intervention was necessary. Our findings tend to favor a positive approach to the performance of a renal biopsy in the management of the nephrotic syndrome in the elderly.

摘要:
We examined autopsy reports and the clinical diagnoses of 600 patients (200 in 1967 and 400 in 1987). For each patient we considered age, diagnostic error, main diseases and presence of multiple pathology. The number of diagnostic errors increased from 1967 to 1987. The diagnostic error was particularly high for pulmonary embolism and septic shock and significantly higher in patients > 65 than ≤ 65 years old. Multiple pathology was higher in old patients: we found 4 or more diseases in 195/270 (72.2%) patients > 65 years and in only 135/330 (40.9%) patients ≤65 years. The average period of hospitalization was directly proportional to the number of diseases present in the same pati
