Intussusception can develop at any age but about 95% of patients are children under 2 years-old. Adult intussusception is a rare condition. Unlike children, nearly all adults with intussusception have a lead point such as benign or malignant small bowel tumors, intestinal tuberculosis, or Meckel's diverticulum. First case is a 48-year-old male who was admitted with 2 days of diffuse abdominal cramping pain and no other associated gastrointestinal symptoms. Barium enema revealed ileocolic intussusception with a round cecal mass after barium reduction. An ileocecectomy was performed electively. The pathologic report was cecal cyst, which was an intraluminal structure with an epithelial lining of colonic mucosa. The second case, a 53-year-old male, was admitted with 1 week of diffuse abdominal cramping pain and watery diarrhea. Barium enema revealed ileocecal intussusception. Emergency surgery (ileocecectomy), revealed a polypoid small bowel mass. The pathologic report was lipoma. Recently, we experienced two cases of adult intussusception and report these cases with a brief review of the literature.

Central nervous system cryptococcosis is common in the AIDS patients with reported incidences ranging from 1.9% to 11.0%. Cryptococcosis may be the initial manifestation of HIV infection or occur simultaneously with other opportunistic infections. HIV-infected patients with central nervous system cryptococcosis complain of fever, headache, nausea and vomiting, and cognitive dysfunction. Meningeal signs and photophobia are less common than in HIV-negative patients. Focal neurologic signs and seizures are uncommon. Disseminated cryptococcosis is often concomitantly found at the time of central nervous system cryptococcosis. We report a case of 49 year-old Korean female with HIV infection who died of disseminated cryptococcosis with autopsy findings.

BACKGROUND: The role of totally implantable central venous port (TICVP) system is increasing. Implantation performed by radiologist with ultrasound-guided access of vein and fluoroscope-guided positioning of catheter is widely accepted nowadays. In this article, we summarized our experience of TICVP system by surgeon and present the success and complication rate of this surgical method. MATERIALS AND METHODS: Between March 2009 and December 2010, 245 ports were implanted in 242 patients by surgeon. These procedures were performed with one small skin incision and subcutaneous puncture of subclavian vein. Patient's profiles, indications of port system, early and delayed complications, and implanted period were evaluated. RESULTS: There were 82 men and 160 women with mean age of 55.74. Port system was implanted on right chest in 203, and left chest in 42 patients. There was no intraoperative complication. Early complications occurred in 11 patients (4.49%) including malposition of catheter tip in 6, malfunction of catheter in 3, and port site infection in 2. Late complication occurred in 12 patients (4.90%). CONCLUSION: Surgical insertion of TICVP system with percutaneous subclavian venous access is safe procedures with lower complications. Careful insertion of system and skilled management would decrease complication incidence.

BACKGROUND: The bcl-2, gene is a newly described oncogene involved in tumorigenesis by blocking apoptosis, or programmed cell death and overexpression of bcl-2 protein has been reported in several malignant tumors such as lymphoma, breast cancer, and lung cancer. Though keratinocyte-derived skiri tumors are one of the most common human tumors the detailed molecular mechanism of the keratinocytic tumors is not clear. Also, the differentiation between basal cell carcinoma(BCC) and trichoepithelioma(TE) is sometirnes difficult clinically and histologically. OBJECTIVE: The purpose of this study is to examine whether there is difference in staining pattern of bcl-2 protein in BCC, TE, squamous cell carcinoma(SCC), and keratoacanthoma(KA). We also evaluated the diagnostic value of expression pattern of bcl-2 protein in distinguishing BCC and TE. METHODS: Routine paraffin sections of formalin-fixed forty-four tissues (19 BCC, 9 SCC, 10squamous cell carcinoma in situ : 5 actinic keratosis [AK] and 5 Bowen disease [BD], 5 keratoacanthoma, and 6 (TE) were labeled with anti-bcl-2 monoclonal antibody using a avidin-biotin peroxidase complex. Normal skin for bcl-2 protein served as negative controls. RESULTS: The results were as follows. l. In normal skin, bcl- 2 positivity was observed in the epidermal basal layer, the basal layer of follicular infundibuium, the mesenchymal cells of the follicular papillae, and the eccrine glands. 2. All cases of BCC and TE showed a positive cytoplasmic staining for bcl-2 proein, but all cases of SCC, AK, BD, and KA were negative. 3. In staining pattern, of bcl-2 protein, BCC showed diffuse staining throughout the tumor lobules. In TE, the basaloid cells lining the periphery of each tumor nests and the papillary mesenchymal bodies stained strongly. CONCLUSION: This study shows that BCC express bcl-2 protein, whereas SCC are negative. Our results indicate that proteon from apoptosis mediated by bcl-2 protein may be involved in the neoplastic growth mechanism of BCC. In addition, the ohserved findings in expression pattern of bcl-2 protein in BCC and TE may be of a diagnostic help in distinguishing the borderline cases.

About 5% of burn patients come with other injuries. When patients with multiple rib fractures are put under general anesthesia, there is a higher rate of a variety of complications, such as hemothorax, pneumothorax, lung contusion, and etc. Also, symptoms of the complications are likely to get worse. Therefore, it is important to decide when it is appropriate to perform surgery. Our hospital delayed operation time on two burn patients who had multiple rib fractures and then performed surgery under general anesthesia, treating patients without any particular complications.

Background and Objectives:
Even though most of the thyroid cancer shows good prognosis, de-differentiated thyroid cancer is still refractory to conventional treatments. Recently, kinase inhibitors including multi-kinase and BRAF inhibitors are widely used for treatment of de-differentiated thyroid cancers, but resistant to single kinase inhibitor treatment eventually encountered. Therefore, combination therapy may have better therapeutic effect than single therapy for thyroid cancer. In this study, we evaluated therapeutic effect of multi-kinase and BRAF inhibitor combination to anaplastic thyroid cancer cell lines with and without BRAF mutation.
Materials and Methods:
We used anaplastic thyroid cancer cell lines with BRAF V600E mutation (8505C) and with NRAS mutation (HTh7). Both cell lines were treated with various concentration of multi-kinase inhibitor (lenvatinib) and BRAF inhibitor (vemurafenib). And combination of various concentration of both kinase inhibitors were used to treat both cell lines. Cytotoxic effect was assessed with cell counting kit-8 and therapeutic effect of single kinase inhibitor therapy and the combination therapy was compared.
Results:
Anti-proliferative effect of vemurafenib on 8505C BRAF V600E -mutated cells was demonstrated from 0.25 μM concentration. However, HTh7 cells with NRAS mutation represented drug resistance up to 4 μM of vemurafenib. In case of lenvatinib treatment as a multi-kinase inhibitor, 8505C and HTh7 cells showed decreased cell viability dose-dependent manner. Combination treatment with vemurafenib and lenvatinib showed synergistic cytotoxic effect in BRAF mutated 8505C cell line, even at lower concentrations.
Conclusion
Combination treatment with multi-kinase inhibitor and BRAF inhibitor showed promising therapeutic results in BRAF mutated anaplastic thyroid cancer cell line.

Azathioprine is frequently used for the treatment of inflammatory bowel diseases (IBD) such as Crohn's disease and ulcerative colitis. Lymphomas, squamous cell carcinomas, and undifferentiated pleomorphic sarcomas have been reported among patients receiving azathioprine therapy. Herein, we report a case of pleomorphic liposarcoma of chest wall which occurred in a 44-year-old man with Crohn's disease taking azathioprine. He was diagnosed with Crohn's disease 3 years ago after suffering from abdominal pain and hematochezia for 12 years. He had been taking 50 mg of azathioprine per day for 23 months when he visited the thoracic and cardiovascular surgery clinic due to right chest palpable mass that had rapidly grown during the past 2 months. Excisional biopsy was performed and the mass was diagnosed as pleomorphic liposarcoma. Therefore, he underwent radical excision of the right chest wall mass, which measured 11.0x6.5 cm in size. He is scheduled to receive radiation therapy and chemotherapy.

BACKGROUND/AIMS: The optimal route for iron administration in anemic patients with inflammatory bowel disease (IBD) has not been determined. The aim of this study was to compare the efficacies of parenteral and oral iron therapy in IBD patients in Korea. METHODS: A retrospective multicenter study was performed. Patients who had been administered parenteral iron were matched to the controls with oral iron at a 1:1 ratio according to age, sex, and type of IBD. RESULTS: Patients that received parenteral iron exhibited increases in hemoglobin levels of ≥20% from the baseline at lower doses and in shorter durations (p=0.034 and p=0.046, respectively). In the multivariate analysis, parenteral iron therapy appeared to be more efficient than oral iron therapy, but this difference was not statistically significant (hazard ratio [HR], 1.552; 95% confidence interval [CI], 0.844 to 2.851; p=0.157). Patients with ulcerative colitis responded better to iron therapy than those with Crohn's disease (HR, 3.415; 95% CI, 1.808 to 6.450; p<0.001). Patients with an initial hemoglobin level of 10 g/dL or higher responded poorly to iron therapy (HR, 0.345; 95% CI, 0.177 to 0.671; p=0.002). CONCLUSIONS: Parenteral iron therapy appears to be more efficient than oral iron therapy. Physicians should focus on the iron deficiency of IBD patients and consider parenteral iron supplements in appropriate patient groups.
