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.

OBJECTIVE: The purpose of this study is to investigate the combined effects of ginkgo biloba extract, ginkgolide A and B and aspirin on SK-N-MC, human neuroblastoma cell viability and mRNA expression of growth associated protein43 (GAP43), Microtubule-associated protein 2 (MAP2), B-cell lymphoma2 (Bcl2) and protein53 (p53) gene in hypoxia and reperfusion condition. METHODS: SK-N-MC cells were cultured with Dulbecco's Modified Eagle's Medium (DMEM) media in 37degrees C, 5% CO2 incubator. The cells were cultured for 8 hours in non-glucose media and hypoxic condition and for 12 hours in normal media and O2 concentration. Cell survival rate was measured with Cell Counting Kit-8 (CCK-8) reagent assay. Reverse transcriptase polymerase chain reaction (RT-PCR) was used to estimate mRNA levels of GAP43, MAP2, Bcl2, and p53 genes. RESULTS: The ginkgolide A and B increased viable cell number decreased in hypoxic and reperfused condition. The co-treatment of ginkgolide B with aspirin also increased the number of viable cells, however, there was no additive effect. Although there was no increase of mRNA expression of GAP43, MAP2, and Bcl2 in SK-N-MC cells with individual treatment of ginkgolide A, B or aspirin in hypoxic and reperfused condition, the co-treatment of ginkgolide A or B with aspirin significantly increased GAP43 and Bcl2 mRNA levels. In MAP2, only the co-treatment of ginkgolide A and aspirin showed increasing effect. The mRNA expression of p53 had no change in all treating conditions. CONCLUSION: This study suggests that the combined treatments of Ginkgo biloba extracts and aspirin increase the regeneration of neuroblastoma cells injured by hypoxia and reperfusion.

PURPOSE: The results for treatment of fistula-in-ano have much improved, along with the development of anatomical knowledge, classification, and operative techniques, during last several decades. The authors retrospectively reviewed the results for treatment of fistula-in-ano, especially complex fistulas, during the last 11 years. METHODS: A retrospective study of fistula-in-ano was performed for 229 patients who had been operated on in St. Benedict Hospital between January 1988 and December 1998. Complex fistulas (IIH, III & IV) were analyzed separately. RESULTS: The most common type was IILs (92 cases, 40.2%), and the most common horseshoe type was IIIBc (5 cases, 2.2%). The average hospital stay was 11.5 days for all fistula-in-ano types, but 15.1 days for complex fistulas. Non-specific inflammation (209 cases, 91.3%) was the most common pathologic finding. Various operative procedures were used : fistulotomy (80 cases, 34.9%), fistulectomy (74 cases, 32.3%), coring out fistulectomy (63 cases, 27.5%), seton technique (11 cases, 4.8%), and muscle-filling technique (1 case, 0.4%). There was no difference in the recurrence rate among the operative types. Various procedures were tried for complex fistulas, but the sphincter-preserving fistulectomy by Takano seemed to have a low recurrence rate and a short postoperative course. However, because of the small number of cases, this difference in recurrence rate and postoperative course was not statistically significant. The overall postoperative complication rate was 7%: anal infection (4 cases, 1.7%), anal bleeding (3 cases, 1.3%), and urinary retention (2 cases, 0.9%). CONCLUSIONS: The operations for most of the fistulae, IH, IL & IIL, were simple and uneventful. However, the operations for complex fistulae were complicated and more skill was required. We have thought Takano's operation to be a good curative procedure with less postoperative deformity and shortened postoperative course. However this research couldn't prove that with statistical significance, probably because of the insufficient number of patients. If further cases are collected and continuous follow-up is done, then a better result can be expected.

PURPOSE: Mistletoe extract was widely used for cancer treatment as complementary or alternative therapy in European area from early twenty century. It is currently used as alternative anti-cancer remedy by piecemeal in domestic medical group, however, the anti-cancer mechanism of mistletoe extract was not known precisely until now. In this study the effect of mistletoe extract on gastric cancer was studied vis cell line experiments. MATERIALS AND METHODS: The SNU719 gastric cancer cell line was used, and ABNOBAviscum-Q and ABNOBAviscum-F were treated to cells as mistletoe extract, or 5-FU and cisplatin were used with mistletoe extract. The cell viability and cell death rate were estimated by CCK-8 assay kit and lactate dehydrogenase (LDH) assay kit in each. Caspase 3 assay kit was used to measure caspase 3 activity. The protein expression amounts of Bcl2, p53, and PTEN were estimated through Western blot analysis. RESULTS: The co-treatments of mistletoe extract Q/F and 5-FU/cisplatin decreased lesser cell viability than only mistletoe treat. Caspase 3 activity was increased 4~6 times in co-treatment of mistletoe extracts and 5-FU than control. Bcl2 protein expression was reduced by mistletoe extracts or anti-cancer drugs, further more, the co-treatment of mistletoe extracts and 5-FU/cisplatin diminished more the expression than only mistletoe treatment. Mistletoe extracts did not affect the protein expressions of p53 and PTEN. CONCLUSION: It was concluded that the anti-cancer mechanism of mistletoe extracts was made by caspase 3 activation and lowered Bcl2 expression, and this apoptosis inducing mechanism was independent to p53.

Background/Aims:
Several clinical factors have been used to predict the response for concurrent chemoradiotherapy (CCRT); however, these factors are insufficient for prognostic predictions. We investigated clinical factors to assess whether they could be used to predict the response to CCRT and the survival of patients with esophageal cancer.
Methods:
Patients with esophageal cancer underwent CCRT from January 2005 to December 2015. Response to CCRT was classified as progressive disease (PD), stationary disease (SD), partial remission (PR), or complete remission (CR). Factors to predict the response to CCRT and patient survival were subsequently investigated.
Results:
A total of 535 esophageal cancer patients underwent CCRT. Four hundred ninety-three patients were followed up, and patient outcomes were investigated. In the adjusted analysis, patients with advanced stage disease (relative risk [RR], 0.28 in stage III and 0.12 in stage IV compared to stage I), poor performance status, circumferential involvement (RR, 0.61), and male sex (RR, 0.31) were less likely to achieve CR. Advanced stage disease (hazard ratio [HR], 1.71 in stage III/IV), poor CCRT response (HR, 2.82 in PR, 4.47 in SD, 4.77 in PD compared to CR), and poor performance status (HR, 1.38 in ECOG 2–4) were found to increase mortality.
Conclusions
Advanced stage disease, poor performance status, male sex, and circumferential involvement were independent predictive factors for a poor response to CCRT. Advanced stage, poor performance status, and poor CCRT response were independent factors for decreased survival.

BACKGROUND/AIMS: The aim of this study was to evaluate the outcome of endoscopic dilation for benign anastomotic stricture after radical gastrectomy in gastric cancer patients. METHODS: Gastric cancer patients who underwent endoscopic balloon dilation for benign anastomosis stricture after radical gastrectomy during a 6-year period were reviewed retrospectively. RESULTS: Twenty-one patients developed benign strictures at the site of anastomosis. The majority of strictures occurred within 1 year after surgery (95.2%). The median duration to stenosis after surgery was 1.70 months (range, 0.17 to 23.97 months). The success rate of the first endoscopic dilation was 61.9%. Between the restenosis group (n=8) and the no restenosis group (n=13), there were no significant differences in the body mass index (22.82 kg/m2 vs 22.46 kg/m2), interval to symptom onset (73.9 days vs 109.3 days), interval to treatment (84.6 days vs 115.6 days), maximal balloon diameter (14.12 mm vs 15.62 mm), number of balloon dilation sessions (1.75 vs 1.31), location of gastric cancer or type of surgery. One patient required surgery because of stricture refractory to repeated dilation. CONCLUSIONS: Endoscopic dilation is a highly effective treatment for benign anastomotic strictures after radical gastrectomy for gastric cancer and should be considered a primary intervention prior to proceeding with surgical revision.

Multiple endocrine neoplasia type 1 (MEN 1) is the association of neoplastic transformation of parathyroid, pituitary, and pancreatic islet cells. This syndrome is inherited as an autosomal dominant trait. A 38-year-old woman presented with general weakness and mental changes. She had experienced same symptoms 7 years ago, after then her weight gradually increased. Insulinoma was suspected by markedly decreased blood glucose level (20mg/dL) and the increased insulin/glucose ratio (0.43) that sampled in emergency room at the time of mental change. Unusually large pancreatic tail mass and Lt, adrenal gland mass were detected by abdominal CT. Percutaneous transhepatic portal vein catheterization with insulin sampling showed sudden step up of insulin/glucose ratio at the middle portion of pancreas. Measuring of basal pituitary hormones as a screening procedure of MEN showed increased basal prolactin level. Combined pituitary stimulation test showed blunted response of prolactin to TRH and sellar magnetic resonance imaging showed intrasellar mass. Thyroid nodule was palpated on her anterior neck. Thyroid scintigram showed cold nodule, and there was no lymphadenopathy around the nodule by the thyroid sonogram. Fine needle aspiration cytology showed benign hyperplastic follicular cells only. Serum ionized calcium and parathyroid hormone level were normal. Under the impression of MEN type I, the distal pancreatectomy, splenectomy, Lt. thyroid lobectomy and Lt. adrenalectomy was performed at the same time. Histologic examination of the surgically removed tissues revealed pancreas islet cell tumor, adrenal cortical adenoma and thyroid adenoma. Transient hyperglycemia was developed after surgical intervention, but thereafter she never felt any symptoms of hypoglycemia till now and her blood glucose showed completely normal level with oral glucose tolerance tests. We present this case with a review of literature.

BACKGROUND: The interest in robotic cardiac surgery has recently grown but there has not been much clinical research reported on this. The aim of this study is to examine our initial experience, since August 2007, with robotic cardiac surgery using the da Vince(TM) surgical system and to evaluate the feasibility and safety of it. MATERIAL AND METHOD: Between August and December 2007, a total of 20 patients underwent robotic cardiac surgery using the da Vinci surgical system. For mitral valve repair (n=11), tricuspid valve repair (n=1), and ASD repair (n=1), cannulation, antegrade cardioplegia and transthoracic aortic cross-clamping were conducted for the right femoral vessels and the right internal jugular vein. For minimally invasive direct CABG (MIDCAB) (n=7), the internal thoracic artery (ITA) was harvested with the da Vinci surgical system. RESULT: The mean age of the patients was 50.1 (range: 26~78) years. Three concomitant Maze procedures and one tricuspid annuloplasty were combined with mitral valve repair. The mean cardiopulmonary bypass time was 208.0+/-61.3 minutes and the aortic cross clamp time was 158.8+/-40.6 minutes. No patients showed more than mild mitral regurgitation after repair and the median hospital stay was 4 days. The robotic-harvested ITA was used for either left ITA (n=6) or bilateral ITA (n=1). The mean harvest time was 43.2+/-12.0 minutes. The harvested ITA showed good flow and it was anastomosed under direct vision after left anterolateral thoracotomy. The patency of all the grafts was 100% (18/18) in MIDCAB. CONCLUSION: Robotic cardiac surgery using the da Vinci surgical system was variously adapted to areas such as mitral and tricuspid valve repair, ASD repair and ITA harvest for MIDCAB. The early results of the robotic cardiac surgery showed its safety and feasibility. With this primary report, we anticipate that clinical applications and further studies on robotic cardiac surgery using the da Vinci surgical system will be actively conducted in Korea.

BACKGROUND/AIMS: The aim of this study was to analyze and propose a treatment strategy after endoscopic resection of superficial esophageal squamous cell carcinoma in a single institution. METHODS: This is a retrospective review of 37 patients who were treated by endoscopic resection during a 6-year period. RESULTS: The mean tumor size was 11.5+/-5.5 mm (range, 3 to 31 mm). Thirty-one lesions (83.8%) were treated by endoscopic submucosal dissection, and six lesions were treated by endoscopic mucosal resection (16.2%). The en bloc resection rate and complete resection rate were 91.9% and 81.8%, respectively. The tumor invasion depth was diagnosed as epithelial in five cases (13.5%), lamina propria mucosa in 12 cases (32.4%), muscularis mucosa in 10 cases (27.0%) and submucosa in 10 cases (27.0%). The complication rate was 13.5% and included three cases (8.1%) of perforation. Ten patients who had muscularis mucosa and submucosa lesions received additional treatments, including six patients who were treated with esophagectomy, three patients who were treated with radiotherapy and one patient who was treated with chemoradiotherapy. One patient with lamina propria lesions received radiotherapy due to a positive resection margin. The median follow-up duration was 22 months (range, 4 to 79 months), and no recurrence or metastasis was noted during follow-up. CONCLUSIONS: Tailored management after endoscopic treatment of superficial esophageal squamous cell carcinoma can offer an acceptable oncologic outcome in early esophageal carcinoma.

Although cardiac myxoma is the most commonly encountered benign cardiac tumor in cardiac surgery practice, recurrent cardiac myxoma is very rare, is most commonly related to the Carney complex, and usually requires multiple cardiac operations with specific requirements in terms of perioperative management. In this report, we describe a patient who experienced the fourth recurrence of cardiac myxoma and review the diagnostic criteria of the Carney complex. This is the first report of such a case in Korea.
