Therapeutic Predictor of Disodium Eromoglycate(DSCG) on Bronchial Asthma / 대한내과학회지

OBJECTIVES: Although DSCG protects against the stimuli of various bronchoconstictor, such as exercise, it is not effective to all patients. There seems to be no therapeutic predictor that determines effectiveness of DSCG on bronchial asthma. Although it is commonly assumed that children with predominantly allergic asthma have a better response to DSCG therapy than adult patient, this has not been convincingly demonstrated, and even adult with late onset nonallergic asthma may benefit. In this study, we evaluated the factors that potentially influenced the ability of DSCG to reduce bronchial hyperresponsibility. METHODS: The treatment groups were sub-divide into effective group(n=14) and ineffective group(n=6) on the basis of significant improvement of followedup PC20 after long term therapy of DSCG. We compared clinical and laboratory data and pulmonary function test between two groups. RESULTS: 1) Disease durtion and pre-treatment pulmonary function (FEV1% predicted, FVC% predicted value) may play a role in determining effectiveness of DSCG on bronchial asthma(p0.05). CONCLUSION: These results show that DSCG is effective in adult chronic asthma and early administration of DSCG, good pulmonary function test and allergic rhinitis history may lead to more favorable outcome.

The effect of 8 French catheter and chest tube on the treatment of spontaneous pneumothorax / 결핵

BACKGROUND: Spontaneous pneumothorax have been managed with a variety of methods. The technique most frequently used is chest tube drainage. Small caliber catheters were first used in the management of pneumothorax complicating the percutaneous needle aspiration lung biopsy, and the try to treat spontaneous pneumothorax also has been reported. However, the value of small caliber catheters in spontaneous pneumothorax has not been fully evaluated. So, we tried to elucidate the efficacy of 8 French catheter in the management of spontaneous pneumothorax. METHOD: From January, 1990, to April, 1994, 44 patients with spontaneous pneumothorax treated at Chung-Ang university hospital were reviewed. The patients were sub-divide into 8 French catheter insertion group (n=21) and chest tube insertion group (n=23). We compared the presence of underlying lung disease, the extent of the collapse, the duration of indwelling catheter and complication between two groups. RESULTS: 1) The duration of indwelling showed no significant difference between 8 French catheter group and chest tube. But, complication after insertion as subcutaneous emphysema was developed in only chest tube group. (p<0.05) 2) In the primary spontaneous pneumothorax, all case of the pneumothorax of which size was less than 50% showed complete healing with 8 French catheter insertion. Whereas the success rate in patients with large pneumothorax (more than 50%) was tended to be dependent on the age. 3) In the patients with secondary spontaneous pneumothorax who were managed with 8 French catheter, the success rate was trended to be high if the underlying disease of pneumothorax was not COPD and if the patient was young. CONCLUSION: These results show that 8 French catheter insertion probably was effective in the pneumothorax less than 50%, the primary spontaneous pneumothorax, young age or secondary pneumothorax not associated with COPD.
