Background: A secondary spontaneous pneumothorax is a complication of an underlying pulmonary disease. In recent years, there have been only a few scattered reports of patients with silicosis also having a pneumothorax. Silicosis, a form of disabling pulmonary fibrosis, is a well-known occupational disease resulting from high-level exposure to silica or silica-containing dusts. The objective of the present study was to elucidate any associations between the occurrence of a pneumothorax, and pulmonary function tests and clinical observations performed prior to the pneumothorax; these two factors may be predictors for a pneumothorax among workers exposed primarily to silica-containing respirable dust. Methods: A diagnosis of silicosis was made on several factors: silica dust exposure, appropriate interval of time after exposure, clinical findings, pulmonary function tests and chest radiological findings. A checklist was designed for collecting data of occupational history, respiratory signs, and symptoms from onset of dust exposure to the occurrence of a pneumothorax. Spirometery was conducted in accordance to the recommendations of standard protocols and guidelines posited by the American Thoracic Society. Autopsies were performed in three cases where the patient had suffered a pneumothorax due to silicosis. Mann—Whitney U-tests and Fisher's exact tests were used to determine any associations between pneumothorax and predictor factors. Results: An association between a progressive decrease in pulmonary function test values and a pneumothorax was observed. The occurrence of a pneumothorax was associated with complaints of pleuretic chest pain, resting dyspnea, respiratory distress, paroxysmal nocturnal dyspnea, orthopnea and crackle. Conclusion: A characteristic decline in pulmonary function test values and the severity of respiratory impairment may facilitate the occurrence of a pneumothorax in silicosis.

OBJECTIVE There have been no reports on the long-term radiographic outcomes of posterior vertebral column resection (PVCR) in patients with congenital scoliosis. The purpose of this study was to evaluate the surgical outcomes and complications after PVCR and its long-term effects on correcting this deformity in children with congenital scoliosis. METHODS The authors retrospectively analyzed the medical records of 45 patients with congenital scoliosis who were younger than 18 years at the time of surgery and who underwent PVCR and fusion with pedicle screw fixation (PSF). The mean age of the patients at the time of surgery was 11.3 years (range 2.4–18.0 years), and the mean length of follow-up was 12.8 years (range 10.1–18.2 years). RESULTS The mean Cobb angle of the main curve was 46.5° before PVCR, 13.7° immediately after PVCR, and 17.6° at the last follow-up. For the compensatory cranial curve, PVCR corrected the preoperative Cobb angle of 21.2° to 9.1° postoperatively and maintained it at 10.9° at the last follow-up. For the compensatory caudal curve, the preoperative Cobb angle of 23.8° improved to 7.7° postoperatively and was 9.8° at the last follow-up. The authors noted 22 complications, and the overall incidence of complications was 48.9%. CONCLUSIONS Posterior vertebral column resection is an effective procedure for managing congenital scoliosis in patients younger than 18 years. Use of PVCR and fusion with PSF for congenital scoliosis achieved rigid fixation and satisfactory deformity correction that was maintained over the long term. However, the authors note that PVCR is a technically demanding procedure and entails risks for major complications and excessive blood loss.
