The prevalence of pulmonary pargonimiasis in Korea has been steadily decreasing due to develop of the public health, and there have been few clinical cases of paragonimiasis infections, especially in pneumothorax. A 22-year-old man referred to emergency department for dyspnea and chest pain. The right lung was totally collapsed on a chest X-ray. We emergently performed a closed thoracostomy with a 28-Fr chest tube. However, the air leak from the chest tube persisted for three days after the closed thoracostomy. A chest computed tomography showed multiple subpleural consolidative nodular lesions and mixed ground-glass attenuation nodules. We potentially suspected a secondary pneumothorax resulting from pulmonary paragonimiasis infection because the patient was a Chinese man who was working at a Korean restaurant. We decided to perform a medical treatment instead of pulmonary wedge resections. The air leak was discontinued three days after the prescription of praziquantel. The patient was discharged nine days after the admission. We suggest that anti-parasitic drugs are very effective in the secondary pneumothorax resulting from paragonimiasis.

This paper reports a case in a 16-year-old female of intrapulmonary teratoma located in the right upper and middle lobes of the lung. The initial symptoms were high spiking fever, cough and chest pain. Initial chest X-ray revealed large homogenous mass in the right upper and middle lung fields. So intercostal tube drainage was done under the impression of the lung abscess. But mass density was remained on the follow-up chest X-ray, the patient had resection of the right upper and middle lobes of the lung. The gross and microscopic findings of the resected specimen revealed characteristic findings of the intrapulmonary teratoma. The patient is asymtomatic at present and living a normal life.

Tension pneumocephalus may follow a cerebrospinal fluid(CSF) leak communicating with extensive extradural air. However, it rarely occurs after diagnostic lumbar puncture, and its treatment and pathophysiology are uncertain. Tension pneumocephalus can develop even after diagnostic lumbar puncture in a special condition. This extremely rare condition and underlying pathophysiology will be presented and discussed. The authors report the case of a 44-year-old man with a basal skull fracture accompanied by pneumothorax necessitating chest tube suction drainage, who underwent an uneventful lumbar tapping that was complicated by postprocedural tension pneumocephalus resulting in an altered mental status. The patient was managed by burr hole trephination and saline infusion following chest tube disengagement. He recovered well with no neurologic deficits after the operation, and a follow-up computed tomography (CT) scan demonstrated that the pneumocephalus had completely resolved. Tension pneumocephalus is a rare but serious complication of lumbar puncture in patients with basal skull fractures accompanied by pneumothorax, which requires continuous chest tube drainage. Thus, when there is a need for lumbar tapping in these patients, it should be performed after the negative pressure is disengaged.

Background ; To evaluate the efficacy of Fibrin glue to decrease recurrence in video-assisted thoracoscopic surgery(VATS) for a treatment of spontaneous penumothorax. Material and Method : All medical records of 17 patients who underwent a thoracoscopic wedge resections of bullae with stapling device with Fibrin glue in our institute between May 1998 and December 1999 were reviewed. variables analyzed include affected sites primary indication of VATS. duration from admission to discharge duration of postoperative stay duration of chest tube drainage recurrence and complication. There were 16 men and 1 woman. Result : There was no evidence of hemodynamic instability or arterial blood gas abnormalities encountered during the procedure. Mean age at the time of the VATS was 26.9 years (range 15 to 61 years) The mean duration from admission to discharge was 7.8 days and mean postoperative stay was 5.1days mean chest tube indwelling period was 4..0 days. There was no recurrence of pneumothorx. Conclusion : Thoracoscopic wedge resections with introduction of fibrin glue are safe and effective and requires only a short hospital stay. We believe that this thoracoscopic technique will further simplify the surgical treatment of pneumothorax.

To compare of quality control for chest radiography between special examination (SEP) and medical institution for pneumoconiosis (MIP). For the first time, we had visited at 33 institutions (SEP; 17 institutions, MIP; 16 institutions) to evaluate the quality control of chest radiography which is used in diagnosis of patients with pneumoconiotic complications. Image quality was rated by two experienced chest radiologists, and evaluated for radiological technique (RT), reading environment (RE) and image quality (IQ) between SEP and MIP according to the guideline published by OSHRI. Generator capacity, used duration and modality of chest radiography equipment were not signigicant difference between SEP and MIP, but there were signigicant difference in tube voltage and grid ratio used for chest radiography except to tube current and exposure time. SEP was statistically significant higher in RT (71.2 vs. 54.5, p=0.015), RE (78.8 vs. 51.5, p=0.007) to MIP, but not significant difference in IQ (64.8 vs. 59.3, p=0.180). For reliable and precisional diagnosis of patients with pneumoconiotic complications, the MIP requires the evaluation and education of quality control for improving chest radiography.

Recently pediatric CT has been performed by reduced dose according to tube current modulation이라고, this fact has a possibility more reduce a dose because of strong affect depend on tube current modulation. Almost all MDCT snow show and allow storage of the volume CT dose index (CTDIvol), dose length product (DLP), and effective dose estimations on dose reports, which are essential to assess patient radiation exposure and risks. To decrease these radiation exposure risks, the principles of justification and optimization should be followed. justification means that the examination must be medically indicated and useful. Results is using tube current modulation이라고 tend to the lower kV, the lower effective dose. In case of use a low dose CT protocol, we found a relatively lower effective dose than using tube current modulation. Average effective dose of our studies(brain, chest, abdomen-pelvis) less than 47%, 13.8%, 25.7% of germany reference dose, and 55.7%, 10.2%, 43.6% of UK(United Kingdom) reference dose respectively. when performed examination for reduced dose, we must use tube current modulation and low dose CT protocol including body-weight based tube current adaption.

Though esophageal cancer was not a common disease, early metastasis and direct extension to adjacent organ were important on the treatment of disease. Therefore, palliative operation was often useful in advanced esophageal cancer. Between June 1985 through July 1985, we treated three cases of inoperable esophageal cancer with Celestin`s endo-esophageal tube by esophageal intubation. Three operations were done under general anesthesia. Celestin`s tube were inserted via oral cavity and additional traction on stomach were applied. After complete insertion of tube was done, the distal end of Celestin`s tube was modified in length. Also stay suture was applied between tube and stomach wall was applied. Postoperative esophagogram revealed good esophageal patency through Celestin`s tube. Clinically, swallowing difficulty was much improved after operation.

Background : Spontaneous pneumothoraces(SP) are divided into primary spontaneous pneumothoraces (PSP) which develop in healthy individuals without underlying pulmonary disorders and secondary spontaneous pneumothoraces(SSP) which occur in those who have underlying disorders such as tuberculosis or chronic obstructive lung diseases. Yet there is no established standard therapeutic approach to this disorder, i.e., from the spectrum of noninvasive treatment such as clinical observation with or without oxygen therapy, to aggressively invasive thoracoscopic bullectomy or open thoracotomy. Although chest tube thoracostomy has been most widely used, the patients should overcome pain in the initiation of tube insertion or during indwelling it potential infection and subcutaneous emphysema. Thus smaller-caliber tube has been challenged for the treatment of pneumothorax. Previously, we studied the therapeutic efficacy of 8 French catheter for spontaneous pneumothorax. But there has been few data for effectiveness of small-caliber catheterization in comparison with that of chest tube. In this study, we intended to observe the long-term effectiveness of 8 French catheter for the treatment of spontaneous pneumothoraces in comparison with that of chest tube thoracostomy. Method : From January, 1990 to January, 1996, sixty two patients with spontaneous pneumothoraces treated at Chung-Ang University Hospital were reviewed retrospectively. The patients were sub-divided into a group treated with 8 French catheter(n=23) and the other one with chest tube insertion(n=39). The clinical data were reviewed(age, sex, underlying pulmonary disorders, past history of pneumothorax, size of pneumothorax, follow-up period). And therapeutic effect of two groups was compared by treatment duration(duration of indwelling catheter or tube), treatment-associated complications and recurrence rate. Results : The follow-up period(median) of 8 French catheter group and chest tube group was 28 and 22 months, which had no statistical significance. Ther was no statistically significant difference of clinical characteristics between two groups with SP, PSP, SSP. The indwelling time of 8 French catheter group was $6.2{\pm}3.8$ days, which was significantly shorter than that of chest tube group in SP, $9.1{\pm}7.5$ days(p=0.047). In comparison of treatment-related complication in PSP, 8 French catheter group as 6.25% of complication showed lower tendency than the other group as 23.8% (p=0.041 ; one-tailed, p=0.053; two-tailed). The recurrence rate in each group of SP was 17.4%, 10.3%, which did not show any statistically significant difference. Conclusion : Treatment with 8 French catheter resulted in shorter indwelling time in sponteous pneumothorax, and lower incidence of treatment-related complication in primary spontaneous pneumothorax. And the recurrence rate in each of treatment group showed no statistically significant difference. So, we can recommend the 8 French small-caliber catheter for the initial therapy for spontaneous pneumothorax for the replacement of conventional chest tube thoracostomy. But further prospective study with more subjects of spontaneous pneumothorax will be needed for the evaluation of effectiveness of 8 French cateter.

Current digital radiographic systems are rapidly growing in clinical applications. The purpose of this study was to evaluate the diagnostic performance of computed radiography (CR) and digital radiography (DR) at different tube voltages in the detection of simulated chest lesions. Patterns of simulated interstitial lung disease, incipient infiltration, and nodules were superimposed over an anthropomorphic chest phantom. A simulated chest phantom radiograph was obtained with CR and DR at different tube voltages (70 kV, 90 kV, and 120 kV). A total of 18,000 observations were analyzed using a receiver operating characteristic (ROC) analysis. The detection of all lesions showed higher $A_z$ values at 70 kV than 120 kV with CR. For the DR, mean $A_z$ values at 70 kV were higher than other tube voltages not all lesions but for micro-nodule interstitial lung disease, linear interstitial lung disease, and incipient infiltration. Based on these results, a clinical study should be performed to judge the use of suitable tube voltage according to the type of detector system and lesions.
