It is commonly believed that the branchial anomalies are persistent remnants of the embryologic branchial apparatus. These anomalies are originated from branchial cleft and most commonly involved in second branchial deft. Clinically they present palpable mass, discharge from fistula, recurrent infection due to obstruction of Gstula tract. As respiratory symptoms, they may present hoarseness, preceeded by or associated with upper respiratory infection. However, it has not been reported that they caused airway obstruction in newborn infants. Wc experienced a case of the fourth branchial deft cyst in a 2 day old infant who showed respiratory difficulty due to airway obstruction.

OBJECTIVES: Cord blood stem cells have been widely used as donor cells for bone marrow transplantation recently. These cells can give rise to a variety of hematopoietic lineages to repopulate the blood. Recent observations reveal that some bone marrow cells and bone marrow stromal cells(MSCs) can grow to become either neurons or glial cells. It is, however, unclear whether or not there exists stems cells which can differentiate into neurons in the blood during the early stages of postnatal life. METHODS: Human cord blood stem cells were prepared from human placenta after full term delivery. To induce neuronal differentiation of stem cells, beta-mercaptoethanol was treated. To confirm the neuro-glial characteristics of differentiated stem cells, immunocytochemical stain for NeuN, neurofilament, glial fibrillary acidic protein(GFAP), microtubule associated protein2(MAP2) was performed. RT-PCR was performed for detecting nestin mRNA and MAP2 mRNA. RESULTS: We showed in this experiment that neuro-glial markers(NeuN, neurofilament, MAP2, GFAP) were expressed and axon-like cytoplasmic processes are elaborated in the cultured human cord blood stem cells prepared from new born placenta after full term delivery. Nestin mRNA was also detected in fresh cord blood monocytes. Conclusions: These results suggest that human cord blood derived stem cells may be potential sources of neurons in early postnatal life.

PURPOSE: To analyse the causes and radiologic findings in patients with mediastinitis and to evaluate theefficacy of chest CT scanning in patients with delayed diagnosis. MATERIALS AND METHODS: Seventeen patients withhistopathologically(n=15) or cliniclly diagnosed(n=2) mediastinitis were involved in this study. Eleven of theformer group underwent surgery, and in four, tube drainage was performed. All underwent chest radiography and CTscanning, and in seven patients, the causes of delayed diagnosis were analysed. RESULTS: The most common cause ofmediastinitis was esophageal rupture (n=11). Others were extension from neck abscess to the mediastinum(n=3),complications after a Benthall procedure(n=1), tuberculous lymphadenitis (n=1) and mycotic aneurysm(n=1). Patientswith esophageal rupture suffered from underlying diseases such as esophageal cancer(n=2), iatrogenic esophagealrupture(n=2), Boerhaave's syndrome(n=2), and esophagitis(n=1). In patients with neck abscess(n=3), each wassecondary to infected cystic hygroma, Ludwig angina, or deep neck infection, respectively. On chest CT, patientswith esophageal rupture(n=11) had an abscess in the posterior mediastinum; nine abscesses extended to the cervicalarea along the retropharyngeal space, and the patient with Ludwig angina had an abscess involving all compartmentsof the mediastinum. Among the total of 17 patients, diagnostic delays were found in seven, while five hadspontaneous esophageal ruptures and two suffered complications after a Benthall procedure and Tbc lymphadenitis,respectively. The causes of diagnostic delay varied. Among seven patients, pnevmonia was initially diagnosed intwo, who were treated ; one had multiorgan failure, and one was suffering from pericardial effusion and lungabscess. In three other patients, chest radiographs initially showed non-specific findings, leading to delayed CTexamination. CONCLUSION: The most common cause of mediastinitis was esophageal rupture, and in these patients,chest radiographs and clinical symptoms were sometimes not specific. CT was valuable for the detection ofmediastinitis, and for early diagnosis can be the modality of choice.

Apert's syndrome is rare autosomal dominant defect characterized by craniosynostosis, midface hypoplasia and symmetrical syndactyly. Multiple surgical procedures will be needed for the child with this syndrome. Especially surgery for craniosynostosis is most often performed between 2 and 6 months of life, a period of physiologic anemia. Perioperative complications can occur from numerous sources-massive blood loss, venous air embolism, cerebral edema, hypothermia and hazardous airway management, thus more monitoring, large bored central venous line and early transfusion are recommended. We report a case of 5 month-old female Apert patient undergoing frontal bone advancement and cranioplasty. At the end of uneventful surgery, we removed endotracheal tube in operating room and permitted early feeding because the procedure was limited above the orbital ridge. As soon as feeding the patient presented cyanosis with generalized seizure. Patient was immediately intubated, sucked out secretions and inhaled with oxygen. Blood gas showed moderate hypoxemia which was improved by oxygen therapy. Suspicious aspiration pneumonia was marked on chest film but disappered I week later. The condition was favorable thereafter and discharged without complication. Keypoints in management of Aperts syndrome are close observation, early detection and preventive treatment of possible complications in perioperative period. (Korean J Anesthesiol 1995; 29: 300~303)

Renal allograft recipients are at risk for Pneumocystis carinii pneumonia (PCP) within the first year following transplantation and during treatment for graft rejection. We experienced two cases of PCP in renal allograft recipients. The first case was a 39-year-old female who had received renal allograft 7 years before. At the time of traosplantation, she was a carrier of hepatitis B surface (HBs) antigen. After transplantation, she had been received the rnaintenance dose of cyclosporine and oral prednisolone. Three months before adrnission, dosage of prednisolone was increased because of the increased serum creatinine level and gene-ralized edema. A week before admission, syrnptom of exertional dyspnea, dry cough, and fever was developed. Chest X-ray film showed streaky interstitial infiltration in both lung fields and chest CT showed diffuse ground-glass appearance. Rroncho- alveolar lavage revealed positive Grocott's methenamine silver stain for numerous clumps of pneumocystis carinii cysts. Despite the aggressive treatment, she died of respiratory and hepatic failure and GI bleeding. Another case was a 40-year-old male who had received renal allograft S years before. He had been received maintenance immune suppressive therapy with cyclosporine and oral prednisolone. He was admitted for evaluation of hypertension and elevated serum creatinine level. After several days of admission, he complained fever, dry cough and dyspnea. X-ray film showed pneumonic infiltration and the bronchial brushing and washing fluid revealed the Pneumocystis carinii cysts that were stained by methenamine silver. He was treated with the full dose of trimethoprim-sulfamethoxazole and clindamycin. Sacrificing the renal allograft, he recovered from Pneumocystis carinii pneumonia.

PURPOSE: Cancer is the most frequent cause of death in Korea. Cancer screening can save lives through early detection. This study was to investigate major cancer screening rates and the reasons for not having been screening. METHOD: 210 participants of registered nurses from 5 general hospitals in Busan, Korea were completed a structured self-administered questionnaire. Data were analyzed using descriptive statistics with SPSS WIN 10.0. Results: The cancer screening rates of the subjects were 53.8% in Pap smear test for cervical cancer, 41.0% in gastroendoscopy for stomach cancer, 15.7% in mammograpy for breast cancer, and 3.8% in colonoscopy. And the higher proportions of having regular screening were 9,5% in Pap smear test and 2.9% in gastroendoscopy. The primary reason related to not having a screening test was 'seems to be healthy'. CONCLUSION: The findings showed the necessity of recognizing and educating Korean nurses to have a regular cancer screening for their health management.

PURPOSE: To compare the performance of a total knee arthroplasty with either a PFC Sigma fixed bearing or a rotating platform in the same patient. MATERIALS AND METHODS: 48 cases (24 patients) that received a PFC Sigma fixed bearing and a rotating platform in both knees, one in each knee. The knee score, functional score, activity level, radiologic analyses through fluoroscope , varus/valgus stress, and subjective satisfaction evaluation were performed at the last follow up in the same patient. RESULTS: There were no significant differences in the knee score, functional score, activity level, radiological findings through fluoroscope, and subjective satisfaction. In the varus/valgus stress views, 3 cases of lateral femoral condylar lift-off were observed in the fixed bearing type and 6 cases of lateral femoral condylar lift-off were observed in the rotating platform type. CONCLUSION: In cases of total knee arthroplasty with PFC Sigma fixed bearing and with rotating platform performed in the same patient, there were no significant differences in the clinical, radiological and subjective satisfaction. However, it is considered that the fixed bearing is more stable in terms of medial and lateral femoral condylar lift-off with varus and valgus stress than rotating platform. Therefore long term follow-up would be necessary.

For many years, the histogenesis of the granular cell tumor was controversial and this resulted in the tumor being given more than 20 synonyms. Abrikossoff, reporting on the fiist granular cell tomor, favored a muscle origin, but other authora have postulated a fibroblastic or a histiocytic origin. Recently, the concept of Schwann cell origin, supported by electron microscopic studies and immunohistochemistry of S-100 protein, has gained wider recognition. Approximately 90 cases of esophageal granular cell tumor have been reported in the literature, representing about 2% incidence of all reported granular cell tumor, In Korea, only four cases of granular cell tumors were reported in the literatures including the cases occuring in the cecum, colon, and anus until now. Recently we experienced 46-years old women with granular cell tumor of the esophagus, which might be the second case in Korean literature.
