Extracorporeal membrane oxygenation (ECMO) has been used successfully in critically ill patients with traumatic lung injury and offers an additional treatment modality. ECMO is mainly used as a bridge treatment to delayed surgical management; however, only a few case reports have presented the successful application of ECMO as intraoperative support during the surgical repair of traumatic bronchial injury. A 38-year-old man visited our hospital after a blunt chest trauma. His chest imaging showed hemopneumothorax in the left hemithorax and a finding suspicious for left main bronchus rupture. Bronchoscopy was performed and confirmed a tear in the left main bronchus and a congenital tracheal bronchus. We decided to provide venovenous ECMO support during surgery for bronchial repair. We successfully performed main bronchial repair in this traumatic patient with a congenital tracheal bronchus. We suggest that venovenous ECMO offers a good option for the treatment of bronchial rupture when adequate ventilation is not possible.

To evaluate the establishment of Mungyong Saejae Natural Ecology Park located in the northwestern Gyongbuk Province, a scientific survey for the mushroom flora of the park was carried out from May to December of 1999. A checklist of the Aphyllophorales collected from the park was prepared. The list included 67 species of 44 genera belonging to nine families in the Aphyllophorales. Among them, seven species, Antrodia malicola, Ceriporia purpurea, Oligoporus leucospongia, Perenniporia tephropora, Phanerochaete xerophila, Sistotrema diademiferum and Vuilleminia comedens, were confirmed as new to Korea and are registered here as unrecorded species along with descriptions and microscopic drawings.

We recently experienced a case of an elderly patient with mediastinal abscess, which is a rare complication of esophageal perforation, in whom dyspnea, chest pain and odynophagia were main clinical symptoms after eating cooked fish. During evaluation, upper mediastinal widening, with air-fluid level, and eaophageal perforation plugged with pus were detected by chest X-ray films and endoscopic examinatien. After draining of pus(about 300 cc) through the perforation site by careful manipulation of endoscope, inner wall of abacess cavity communicating with esophagus could be observed through esophago-mediastinal fistula. For further management, drainage procedure of mediastinal abscess, esophageal diversion and feeding gastrostomy were done.

Malignant histiocytosis is a rare, usually fatal malignant neoplasm of reticuloendothelial systems. The disease is associated with fever, malaise, weight loss, hepatosplenomegaly, lymphadenopathy, pancytopenia, jaundice, and purpura. A 44-year-old female patient is described who had multiple, purple crusted nodules and plaques in the skin. In the laboratory study, pancytopenia was noted on the peripheral blood. In addition many atypical histiocytes were seen on the bone marrow aspiration. A lesional biopsy showed nodular infiltrations of atypical histiocytes in the dermis and some erythrophagocytosis was seen. Immunohistochemically, the histiocytes were weakly stained for lysozyme and α-l-antichymotrypsin, but were unstained for S-100 protein, cytokeratin, CEA(carcinoembryonic antigen), pan T/B marker CD30(ki-1), UCHL-1 LCA(leukocyte common antigen), and α-l-antitrypsin.

Most authorities including WHO recommended immununizing infants with BCG as early as possible in areas prevalent with tuberculosis, however the optimal time for immunization has not well been characterized. Therefore the investigation was undertaken by vaccinating various infant groups of different ages with BCG and subsequently evaluating for adverse effects and tuberculin reactions, in order to contribute to undestanding the optimal time for immunization. Four hundred eighty three infants from the newborn nursery and the well baby clinic of Hanyang University Hospital who had no family history of tuberculosis were divided into three groups; group I of infants immunized within 7 days after birth, group II of infants immunized at about 1 month of age and group III of infants immunized at about 3 months of age. To each infant 0.1 ml of BCG(Institute Merieux, France) was administered intradermaly and approximately 3 months later tuberculin skin test using 5 TU PPD (NIH, Korea) was performed. Adverse reactions following BCG vaccination such as temperature elevation, induration alone or with suppuration at or near the injection site, and lymph node enlargement were also analyzed. The summary of the results is as follows. 1) Distribution of diameters of induration on tuberculin skin test illustrated incomplete bimodal configuration in all three different age groups. The means 2 standard deviations of diameters of indurations distributed on the main bells were 10.07 4.52 mm in group I, 10.65 3.82 mm in group II, and 10.83 5.08 mm in group III, and were not significantly different. 2) Criteria for positive tuberculin reaction was diameters of indurations equal to or greater than 6mm, 2 standard deviations below the mean values of diameters of indurations on the main bells. 3) The positive tuberculin reaction rates of 85.8% in group II and 88.6% in group III were significantly greater than 74.1% in group I. 4) Incidence of complications following BCG vaccination including temperature elevation, induration with suppuration, and localized lymphadenopathy was not different among three groups and the serious complications such as temperature elevation and lymphadenopathy were minimal. The data indicate that it is appropriate to immunize infants with BCG at about one month of age and the incidence of complications following BCG vaccination was not different among three infant groups of different ages.

Peri-implantitis could be the result of biomechanical and occlusal overload as well as microbiologic invasion. The dental implant may be more susceptible to dental plaque than the natural tooth, as the predictability of a stable soft tissue attachment complex has not yet been confirmed. With the development of peri-implantitis, the implant surface would be exposed to the oral environment and becomes coated with bacteria. The objective of therapy for this condition is to regain integration of the implant with bone. Since fibroblast adherence to surfaces is impeded by endotoxin, it would seem that decontamination would be desirable to obtain maximum osseointegration. The purpose of this study was to determine whether various chemotherapeutic and mechanical treatments(distilled water, air-powder abrasive, hypersaturated citric acid, tetracycline) can detoxify contaminated titanium implant surface by means of kinetic LAL test. Experimental rough surface titanium disks were fabricated. All of them were divided into two groups(A.a group and P.g group) and each contaminated by A. actinomycetemcomitans and P. gingivalis suspension. Contaminated disks were treated with distilled water, air-powder abrasive, citric acid and tetracycline, and then all disks were placed into LPS-free water for elution. The results were as follows : 1. In A.a group, LPS elute level of all test groups were significantly lower than control group(p<0.05). 2. In A.a group, LPS elute level of test 2, test 3 and test4 groups were significantly lower than that of control group(p<0.05). But, among the test 2, test 3, test4 groups, the significant differences were not detected. 3. In P.g group, LPS elute level of test 2, test 3 and test 4 groups were lower than that of control group(p<0.05). But, among the test groups, the significant differences were not detected. From the result of this study, it would be concluded that air-powder abrasive, hypersaturated citric acid and tetracycline treatments may be effective at reducing endotoxin level on rough titanium implant surfaces, and can be clinically used. But the treatments in peri-implantitis differentially impact osseointegration making one method clinically superior. To gain this knowledges, further molecular biologic and histopathologic studies should be developed.
