Although percutaneous abscess drainage has become and accepted alternative from of therapy for selected patients with abscess, it is well known that there are several factors in the failure of adequate drainage such as pre-and post- procedural management, technique itself, various features of abscess, and selection and application of catheters. Among these factors, we made an experiment about drain efficacy of commonly used various catheters with different viscosities of water-glycerin solution under the two different pressure gradients. The experimental values of flow rate were lower than than the calculated values. An efficacy of experimental value was 4-14%. Because the inner diameter of fittings and stopcocks was usually smaller than the inner diameter of catheters, these factors also affected the drain efficacy. Finally, we though that it will be very helpful to the treatment of patients as well as to study about the catheter drainage, if the drain efficacy of individual catheters has been notified.

BACKGROUND: Although there have been few reports about minimal skin incision for the repair of congenital heart lesions, minimizing an unsightly scar is a particularly important factor in growing children. We have adopted a technique that permits standard full sternotomy, conventional open chest cardiopulmonary bypass, aortic cross-clamping, left atrial vent, and antegrade cardioplegia with minimal surgical scar. MATERIAL AND METHOD: With minimal skin incision and full sternotomy, 40 patients with congenital heart disease underwent open heart surgery from April 1997 through September 1997. Defects repaired included 30 ventricular septal defects, 4 atrial septal defects, and 1 sinus Valsalva aneurysm in 35 children(M:F=17: 18), and 3 Atrial septal defects, 1 ventricular septal defect, and 1 partial atrioventricular septal defect in 5 adults(M:F=1:4). Midline skin incision was performed from the second intercostal space to 1 or 2 cm above the xiphoid process. For full sternotomy, we used the ordinary sternal saw in sternal body, and a special saw in manubrium under the skin flap. During sternal retraction, surgical field was obtained by using two retractors in a crossed direction. RESULT: The proportion of the skin incision length to the sternal length was 63.1+/-3.9%(5.2~11cm, mean 7.3cm) in children, and 55.0+/-3.5%(10~13.5cm, mean 12cm) in adults. In every case, the aortic and venous cannulations could be done through the sternal incision without additional femoral cannulation. There was no hospital death, wound infection, skin necrosis, hematoma formation, or bleeding complication. CONCLUSION: We conclude that minimal skin incision with full sternotomy can be a safe and effective alternative method for the repair of congenital heart diseases in children and adults.

BACKGROUND: As the early outcome after coronary artery bypass grafting(CABG) has been stabilized, neurologic complication has now become one of the most important morbidity. The aim of this study was to find out the risk factors associated with the neurologic complications after CABG. MATERIAL AND METHOD: In 351 patients who underwent CABG, the incidence and features of neurologic complications, with associated perioperative risk factors, were retrospectively reviewed. Neurologic complication was defined as a new cerebral infarction confirmed by postoperative neurologic examination and radiologic studies, or delayed recovery of consciousness and orientation for more than 24 hours after the operation. RESULT: Neurologic complications occurred in 18 patients(5.1%), of these nine(2.6%) were diagnosed as having new cerebral infarctions(stroke). Stroke was manifested as motor paralysis in four patients, mental retardation or orientation abnormality in four, and brain death in one. Statistical analysis revealed the following variables as significant risk factors for neurologic complications by both univariate and multivariate analyses: cardiopulmonary bypass longer than 180 minutes, atheroma of the ascending aorta, carotid artery stenosis detected by Duplex sonography, and past history of cerebrovascular accident or transient ischemic attack. Age over 65 years, aortic calcification detected by simple X-ray, and intraoperative myocardial infarction were significant risk factors by univariate analysis only. Neither the severity of carotid artery stenosis nor technical modifications such as cannulation of the aortic arch or single clamp technique, which were expected to affect the inciden e of neurologic complications, had significant relationship with the incidence. CONCLUSION: This study confirmed the strong association between neurologic complications after CABG and atherosclerosis of the arterial system. Therefore, to minimize the incidence of neurologic complications, systematic evaluation focused on atheroscleroti.

PURPOSE:To identify the main toxic gas released from salted radish in rice bran(Dan-Mu-Ji) and to introduce the radiological findings of the patient who was exposed to the gas. MATERIALS AND METHODS: Chest radiographs and CT scans of one survivor among three men who were exposed to the gas from Dan-Mu-Ji were reviewed. Gas obtained from the closed bottle containing Dan-Mu-Ji was analized by using the gas chromatography. RESULTS: The radiographic examinations of the survivor were suggestive of pulmonary edema with it's rapidly improving consolidations in both lung. The headspace gas within the bottle containing Dan-Mu-Ji was mainly composed with carbon dioxide, ethyl alcohol and hydrogen sulfide, of which hydrogen sulfide was considered the main toxic gas released. CONCLUSION: Under the anaerobic condition, Dan-Mu-Ji released toxic hydrogen sulfide. Inhalation of hydrogen sulfide might produce non-cardiogenic pulmonary edema.

BACKGROUND: Elderly-onset rheumatoid arthritis (EORA) is considered to be different from younger-onset rheumatoid arthritis (YORA) in clinical manifestations, laboratory indices, and in prognosis. However, the differences between these two diseases have not been clearly defined. The aim of this study was to more clearly define the clinical characteristics of EORA. METHODS: We retrospectively reviewed 50 EORA and 58 YORA patients who met the classification criteria established by the American College of Rheumatology (ACR). The two groups (EORA and YORA) were compared by three criteria. First, we considered the patterns of the joints involved and the presence of rheumatoid nodules. Second, we compared the disease activity indices and the level of auto-antibodies. Finally, we compared the use of medications. RESULTS: The mean age-of-onset and the women-to-men ratio in the EORA group was 66.2+/-5.5 years and 2.1:1, respectively. There was more large joint involvement seen in the EORA group. The titer of disease activity indices (ESR, CRP) and positive rate of auto-antibodies (rheumatoid factor, ANA, but not anti-CCP antibody) were also higher in the EORA group. We found no differences in the prescribed medications between the two groups. CONCLUSIONS: From these studies, we believe that EORA has higher disease activity indices at onset and greater joint involvement, along with higher titers of auto-antibodies as compared to YORA.

Authors analyzed the findings of findings of chest radiographs and high-resolution CT(HRCT) of chronic mercury vapor poisoning in 12 patients who were diagnosed by previous working history for mercury-thermometer and high level of mercury in blood and urine. The purpose of this paper is to introduce the HRCT findings of chronic mercury vapor poisoning. Duration of mercury exposure was ranged from 10 to 41 months(mean, 21.8 months). Estimated value of serum mercury was ranged from 3.6 to 8.7µg/dl(mean, 5.3 µg/dl: normal value is less than 0.5µg/dl). Estimated value of mercury in urine was ranged from 104 to 482µg/1(mean, 291.4µg/1: normal value is less than 20µg/1). Chest radiographs showed positive findings such as ground-glass opacities and peribronchial cuffings in only 2 out of 12 patients, but HRCT showed positive findings such as ground-glass opacities in 8 patients, peribronchial cuffings in 7 patients, centrilobular abnormalities in 5 patients, interface sign in 4 patients, interlobular septal thickening with intralobular lines in 2 patients and lobular consolidation in one patient. In conclusion, chest HRCT is superior to chest radiograph to show the pulmonary manifestation of chronic mercury vapor poisoning. In patients with chronic mercury vapor poisoning, HRCT findings of centrilobular distributed ground-glass opacities and peribronchial cuffinges are characteristic.

BACKGROUND: It is not easy to surgically correct caustic pharyngeal strictures and a lot of effort is required to restore normal swallowing after the surgery. The authors reviewed the course in patients who underwent pharyngocolostomy. MATERIAL AND METHOD: From August 1995 to March 1998, 6 patients with caustic stricture underwent esophageal reconstruction surgery. The time of injury to the replacement of the esophagus was from 3 months to 2 years and 4 months. The left colon was used in all patients. The surgical route was used under the sternum in 5 patients and through the esophageal hiatus in 1 patient. In the cervical anastomoses, the cervical pharyngocolic anastomosis was performed on the left pyriform sinus after a partial resection of the thyroid cartilage in 3 patients and on the posterolateral aspect of the inferior pharyngeal constrictor in 3 patients. RESULT: Postoperative complications consisted of a dysphagia in 3 patients and left vocal cord palsy in 1 patient. There was no cervical anastomotic stricture. Revisional procedures consisted of an esophageal dilation and free jejunal graft in 1 patient, supraglottic scar band resection in 1 patient, and colonic mucosal resection in 1 patient. Swallowing training was required in the 3 patients with dysphagia. Restoration of normal swallowing was obtained in all patients between the 9th and the 303rd day. CONCLUSION: Pharyngocolostomy is a satisfactory method of treatment for patients with intractable caustic stricture. Pharyngocolojejunostomy is an effective alternative for esophagocologastrostomy in cases where gastric outlets are involved.

The Korean Journal of Thoracic and Cardiovascular Surgery 1998;31(6):638-641
A recurrent myoepithelioma of the lung in a 36-year-old man is reported. The neoplasm showed histologic features identical to those described in myoepitheliomas of major and minor salivary glands on the basis of Dardick's morphological classification of Myoepitheliomas. He was treated totally with surgical en-bloc resection including the chest wall. The tumor was found to be well encapsulated, and it appeared to be mainly composed of plasmacytoid cells and clear cells with occasional microcystic spaces in a solid growth form by light microscopy. Immunocytochemical, ultrastructural and flow-cytometrical studies supported myoepithelioma differentiation.
