In this article, we report a rare case of a 22-year-old male with bilateral pulmonary sequestration, treated with embolization and surgical resection. The initial plan involved staged bilateral lobectomy for both lungs and prophylactic embolization of feeding vessels for preventing unexpected hemorrhage during operation. Symptomatic right lower lobe was resected with video-assisted thoracic surgery after embolization, and the patient refused surgery of left lower lobe upon symptomatic relief. The two-year follow-up examination revealed that the patient was healthy and had no relevant discomfort.

OBJECTIVE: This study was to investigate the generation of the functional neuron derived from human embryonic stem(hES,MB03) cells on in vitro neural cell differentiation system. METHODS: For neural progenitor cell formation derived from hES cells, we produced embryoid bodies (EB: for 5 days, without mitogen) from hES cells and then neurospheres (for 7~10 days, 20 ng/ml of bFGF added N2 medium) from EB. And then finally for the differentiation into mature neuron, neural progenitor cells were cultured in i) N2 medium only (without bFGF),ii) N2 supplemented with 20 ng/ml platelet derived growth factor-bb (PDGF-bb) or iii) N2 supplemented with 5 ng/ml brain derived neurotrophic factor (BDNF) for 2 weeks. Identification of neural cell differentiation was carried out by immunocytochemistry using betaIII-tubulin (1:100) and GFAP (1:500). Also, generation of functional neuron was identified using anti-glutamate (Sigma, 1:1000), anti-GABA (Sigma, 1:1000), anti-serotonin (Sigma, 1:1000) and anti-tyrosine hydroxylase (Sigma, 1:1000). RESULTS: In vitro neural cell differentiation, neurotrophic factors (PDGF and BDNF) treated cell groups were high expressed MAP-2 and GFAP than non-treated cell group. The highest expression pattern of MAP-2 and betaIII-tubulin was indicated in BDNF treated group. Also, in the presence of PDGF-bb or BDNF, mostof the neural cells derived from hES cells were differentiated into gultamate and GABA neuron in vitro. Furthermore, we confirmed that there were a few serotonin and tyrosine hydroxylase positive neuron in the same culture environment. CONCLUSION: This results suggested that the generation of functional neuron derived from hES cells was increased by addition of neurotrophic factors such as PDGF-bb or BDNF in b-FGF induced neural cell differentiation system and especially gultamate and GABA neurons were mainly produced in the system.

Tuberculous lymphadenitis is easily mistaken for an infection by only mycobacterium tuberculosis. However, many cases reveal atypical mycobacterium. Treatment of atypical mycobacterium differs from that of M. tuberculosis and M. bovis. Usual anti-tuberculous medication is the response to M. tuberculosis and M. bovis, but not to atypical mycobacterium. Excision and antibiotic therapy is the known treatment of choice for atypical mycobacterium. We used the polymerase chain reaction(PCR) for differential diagnosis of tuberculosis from lymphadenitis, and by using PCR we were able to differentiate the infecting organism as typical or atypical mycobacterium. We excised 50 case of cervical lymphadenitis, and PCR was done with Primer I(IS6110), which is specific for M. tuberculosis and M. bovis, and with Primer II(65 KDa Ag), which covers all mycobacterium species. The results obtained by PCR were compared with the pathologic results(control): sensitivity 81.8%, specificity 88.9%, false positive ratio 11.1%, false negative ratio 18.2%, typical mycobacterium 45.5%, and atypical mycobacterium 45.5%. These findings suggest that PCR is a good diagnostic tool for the early detection of tuberculous lymphadenitis and for differentiation of mycobacteria in cervical lymphadenitis.

This study was carried out to investigate the development rates of human embryos co-cultured with cumulus cells to each blastocyst stage. Human zygotes were co-cultured on cumulus cell monolayer in YS medium supplemented with 20% hFF. On day 2, if patient had four or more 'good' embryos(regular blastomeres without fragmentation), embryos were further cultured for 72hrs. Blastocysts on day 5 were classified into early blastocyst (ErB), early expanding blastocyst (EEB), middle expanding Blastocyst (MEB), and expanded blastocyst (EdB) on the basis of their morphological aspects of trophectoderm cells and blastocoele. Subsequently, maximum 3 of best blastocysts were transferred in 486 cycles. The results in this study were as follows: Patients who had four or more 'good' embryos on day 2 were 498 persons, but patients whose embryos could not be transferred due to failure in development to the blastocyst stage on day 5 were 12 persons (2.4%). The development rate of embryos to the blastocyst stage was 58.2% (2,885/4,957) on day 5, and the rates that developed to the ErB, EEB, MEB, and EdB stage were 15.0% (743/4,957), 14.9% (739/4,957), 14.4% (714/4,957), and 13.9% (689/4,957), respectively. Total 1366 blastocysts were transferred in 486 cycles (mean number=2.81). The implantation rate and the ongoing implantation rate obtained by observing the number of G-sac and FHB were 29.9% (409/1,366) and 22.5% (308/1,366), respectively. The clinical pregnancy rate was 51.2% (249/486), and the ongoing pregnancy rate was 39.1% (190/486). Among women showing ongoing pregnancy, women with singleton were 50% (95/190), women with twin were 37.9% (72/190), and women with triplet were 12.1% (23/190). Although triplet pregnancy rate in this study was high such as 12.1%, because many blastocysts with high viability were produced in our co-culture system using cumulus cells on day 5, we really believe that a multiple pregnancy except twin should not occur by selecting good embryos for maximum two blastocyst transfer. These results demonstrate that autologous cumulus cells may be used for the production of blastocysts with high developmental competence, and the use of autologous cumulus cells to be collected easily, and to be treated conveniently at OPU must be an effective means for obtaining high implantation and pregnancy rate.

A 46-year-old man presented with a lateral thoracic meningocele associated with cutaneous neurofibromatosis type I and kyphoscoliosis of the thoracic spine upon medical examination. In the majority of such cases, these meningoceles remain asymptomatic, but surgery is indicated when giant or symptomatic cysts are present. The large thoracic meningocele was successfully extirpated through the transthoracic approach in combination with lumbar puncture and cerebrospinal drainage for decompression of the cyst.

BACKGROUND: We analyzed the results of surgical reduction and fixation of ribs under thoracic epidural anesthesia and analgesia (TEA) in patients who had no more than 3 consecutive rib fractures with severe displacement to examine the clinical usefulness of this method. MATERIALS AND METHODS: From May 2008 to March 2010, 35 patients underwent surgical reduction and fixation of ribs under TEA. We reviewed the indications for this technique, number of fixed ribs, combined surgical procedures for thoracic trauma, intraoperative cardiopulmonary events, postoperative complications, reestablishment of enteral nutrition, and ambulation. RESULTS: The indications of TEA were malunion or nonunion of fractured ribs in 29 (82.9%; first operation) and incompletely ribs under previous general anesthesia in 6 (17.1%; second operation). The average number of fixed ribs per patient was 1.7 (range: 1~3). As a combined operation for thoracic trauma, 17 patients (48.6%) underwent removal of intrathoracic hematomas, and we performed repair of lung parenchyma (2), wedge resection of lung (1) for accompanying lung injury and pericardiostomy (1) for delayed hemopericardium. No patient had any intraoperative cardiopulmonary event nor did any need to switch to general anesthesia. We experienced 3 postoperative complications (8.6%): 2 extrapleural hematomas that spontaneously resolved without treatment and 1 wound infection treated with secondary closure of the wound. All patients reestablished oral feeding immediately after awakening and resumed walking ambulation the day after operation. CONCLUSION: Thoracic epidural anesthesia and analgesia (TEA) may positively affect cardiopulmonary function in the perioperative period. Moreover, this technique leads to an earlier return of gastrointestinal function and early ambulation without severe postoperative complications, resulting in a shortened hospital stay and lowered costs.

We report a rare case of a 47-year-old male with posttraumatic phlegmasia cerulea dolens caused by a ruptured right external iliac vein and treated with an endovascular venous stent graft. The patient was the victim of motor vehicle accident, and suffered direct injuries to the head and abdomen. The patient had a cyanotic and swollen right lower leg. Abdominal and lower extremity computed tomography angiography revealed a large retroperitoneal hematoma caused by a ruptured right external iliac vein, and grade I liver injury. The right external iliac vein rupture was successfully treated with a venous stent graft, followed by inferior vena cava filtering, because a venous thrombus was identified below the stent graft. He initially was hemodynamically unstable but recovered following treatment. The patient was comatose when presenting at the emergency department. He was discharged, fully recovered, on hospital day 18.

Odontogenic carcinosarcoma is an extremely rare malignant odontogenic tumor with only a few reported cases. It is characterized by a true mixed tumor showing malignant cytology of both epithelial and mesenchymal components. It has been assumed to arise from pre-existing lesions such as ameloblastoma, ameloblastic fibroma, and ameloblastic fibrosarcoma. To date, the reported cases have exhibited considerably aggressive clinical behavior. The case of an odontogenic carcinosarcoma in the mandible of a 61-year-old male is described herein. The tumor destroyed the cortex of the mandible and invaded the adjacent tissues. Treatment was performed by surgical resection and reconstruction. The purposes of this article are to introduce odontogenic carcinosarcoma through this case study, to distinguish it from related diseases and to discuss features of the tumor in the existing literature.
