Respiratory infections of 19 subjects of advanced age and/or with underlying respiratory disease were treated with cefoperazone (CPZ) and its clinical effects were studied. Sixteen subjects suffered from respiratory tract infection and 3 subjects had pneumonia. The age of the subjects ranged from 39 to 77 years with the mean of 63.8, 7 of them being more than 70 years of age. The underlying respiratory diseases included chronic pulmonary emphysema in 6 subjects, diffuse panbronchiolitis in 3, bronchiectasis in 3, silicosis in 2 and one each of chronic bronchitis, pulmonary fibrosis, lung cancer and old pulmonary tuberculosis. One case, 75 years of age, had renal insufficiency. The daily dose of CPZ was 4 grams in 18 of the 19 subjects and the duration of administration ranged 5 to 22 days. The remaining 1 subject received 2 g of CPZ daily for 6 days. Clinical effects were judged from the changes in fever, cough, amount of sputum, dyspnea, rales, cyanosis, chest X-ray, white blood cell counts, CRP, erythrocyte sedimentation rates and results of sputum culture. Clinical effects were good in 16 subjects, fair in 1, and poor in 2. Bacteriological follow-up was carried out in 13 subjects. Infecting bacteria were eliminated from 5 subjects, reduced in 2 and, in 4 subjects, they were replaced by other bacteria. In 1 subject, P. aeruginosa was isolated from sputum even after the treatment with CPZ, and in another subject H. influenzae relapsed immediately after the cessation of the CPZ treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

Pulmonary auscultation, pulmonary function tests and radiological examination were done in 127 hospitalized patients with silicosis. Fine crackle (FC) was heard in 21.3% of patients, coarse crackle (CC) in 28.5%, rhonchi or wheeze (RorW) in 25.2% and friction rub (FR) in 5.5%. In complicated silicosis the incidence of rales was paradoxically lower than in simple silicosis (54.6 vs. 83.3%, respectively, p less than 0.05). In simple silicosis, patients with CC and/or RorW had lower %VC and FEV1/FVC%, but in complicated silicosis, the relation between the presence of rales and pulmonary functional status was not so apparent. These results suggest that in relatively advanced silicosis, all kinds of rales are heard, and in simple silicosis, rales are useful indicators of physiological impairment, but in complicated silicosis, they do not seem to be so useful.

After a period of 10 years the authors reexamined the respiratory health status of 381 dust-exposed males. Of the lung function values examined Raw, RV/TLC%, VC, TGV and PaO2 were found to be of significant prognostic importance. Among the radiological changes characteristic of silicosis the most serious B-C category, among the respiratory complaints dyspnoea accompanied by regular cough and expectoration, and among the physical changes extended rhonchi and rales accompanied by an emphysematous thorax are to be considered as most essential with respect to prognosis. Smoking habits significantly affected the total death rate, but did not prove to be significant with regard to respiratory death. In the development of bronchial obstruction recurrent febrile respiratory diseases proved to be more important than smoking habits and mild bronchitic complaints.

A 60-year-old stonemason, suffering for many years from joint pains and exertional dyspnoea, developed a high fever with weight loss. Physical examination revealed reddening of light-exposed skin areas, fine rales and overly warm and reddened hand and knee joints. Abnormal laboratory findings were increased erythrocyte sedimentation rate of 66 mm/h, C-reactive protein concentration of 1 mg/dl, haemoglobin of 9.4 g/dl and white cell count of 3300/microliters. Urine contained albumin (100 mg/dl) and cylinders. Titres of both antinuclear and anti-ds-DNA antibodies were elevated (1:2560 and > 97 U/ml, respectively). The chest radiography showed enlarged hili, as well as reticular and nodular shadows which histologically showed silicosis. Systemic lupus erythematodes was diagnosed and the patient was treated with prednisone (2 mg/kg daily), the dosage being reduced to 12 mg daily within 3 months. When the joint pains recurred, azathioprine (50 mg daily) was added for 24 months. At present he is receiving prednisone (12 mg daily) and there has been no recurrence for 4 years.

We describe six cases of acute silicosis which were characterised by an intense exposure to pure silica; there was a rapid onset with diffuse abnormalities on the radiological image and severe respiratory abnormalities. The duration of occupational exposure to silica was four to eighteen years. Three patients presented with a cough associated with disabling dyspnoea (stage III and IV). The physical examination showed finger clubbing in three patients and rales and crepitations on auscultation in two patients. There was general debility in four of the cases with weight loss. The chest x-ray showed a rapid progress with confluence of the diffuse nodular opacities. Respiratory function tests showed a restrictive ventilatory defect (mean +/- standard error of mean: TLC 67 +/- 5%, Vital Capacity +/- 7%, FEV1 63.5 +/- 6%) and alteration in the transfer factor for carbon monoxide (DLCO: 49.5 +/- 5%). The initial broncho-alveolar lavage showed a lymphocytosis (23.6 +/- 4.2%) associated with an alveolar neutrophilia (7 +/- 2.5%). A lung biopsy was carried out in three patients and a transbronchial biopsy in one patient confirming the diagnosis of silicosis in three cases and of silicoproteinosis in one case. After a period of eighteen months to 14 years, four patients died either due to cardiopulmonary complications of their disease (two cases) or to intercurrent disorders (two cases). The last two patients are currently stable.
