We report a case of anal squamous cell carcinoma extended to the rectal mucosa that was clinically mistaken for rectal adenocarcinoma and literature reviwed. Sigmoidoscopic finding showed spherical shaped elevated lesion with central ulceration, interpreted as rectal adenocarcinoma in the distal portion of rectum. Anal squamous cell carcinoma is very rare among gastrointestinal cancer. Pathological study of the biopsy specimen demonstrated squamous cell carcinoma and normal rectal glands. Sigmoidoscopic finding of the presented case showed the ulcerarive lesion contineuosly extended from anal verge upward to the rectum. We postulate that the presented case is primarilly originated from the anal squamous cell carcinoma extended proximally to the rectum. Immunohistochemical stain(p-63) of the biopsy specimens showed squamous cell carcinoma. This patient has been completely recovered after treartment of chemoradiation and trans-anal excision. We present a case of anal squamous cell carcinoma invading rectal mucosa clinically mistaken for rectal adenocarcinoma and literature reviewed.

This research had been conducted to investigate the influence relationships between the motivation for participating in the boarding event, the level of the emotional involvement, and the citizen customers' behaviors of the cruise tourists. And the significance lies in the establishment of the concepts of the variables regarding which the researches have been inadequate. Regarding the questionnaire survey investigation, it had been proceeded with the boarders of Victoria, a leased cruise ship, as the subjects for 2 months from June 2017 until August 2017. And, excluding the insufficient samples, the analysis was carried out with the samples of the 300 copies. As a result of the research, it appeared that, among the motivations to participate, the deviation, the novelty, and the amusement had the influences on the level of the emotional involvement, and the educationality was dismissed. Also, because, regarding the level of the emotional involvement, it appeared that it had the influences on the customers' love, the customer's cooperation, and the customers' participation, it was confirmed that the level of the emotional involvement has the influence on the citizen customers' behaviors.

The standard treatment of pancreatic necrosis has been surgical necrosectomy. There has been debate on whether early surgical intervention can reduced by infected pancreatic necrosis (IPN). Early emergency laparotomy and multiple organ failure remain associated with high mortality. However, reports have presented during the last 10 years of survival of severe acute pancreatitis with medical management. Large and multicenter study showed that about two thirds of patients with necrotizing pancreatitis can be treated conservatively with relatively low mortality. Patients with IPN benefit from postponding intervention and minimal invasive treatment. We reviewed 4 literatures including 2 Korean institute reseached reports concerning non-surgical, conservative treatments of necrotizing pancreatitis including IPN. Large and multicenter study showed that about two thirds of patients with necrotizing pancreatitis can be treated conservatively with relatively low mortality.

Purpose: The purpose of this study was to evaluate the effectiveness of the platelet-rich fibrin (PRF) used in combination with the porcine cancellous bone as a scaffold, in promoting bone regeneration in the bone defects ofthe rabbit calvaria. Methods: Ten rabbits were used in the study. Three round-shaped defects (diameter 8.0 mm) were created in the rabbit calvaria and were filled with nothing (control group), porcine cancellousbone (Experimental Group 1, porcine bone) and PRF-mixed porcine cancellous bone (Experimental Group 2). TS-GBB is a xenogenic bone-substitute product comprised of a high heat-treated mineralized porcine cancellous bone. Animals were sacrificed at 6 weeks and 12 weeks for the histological and radiographic evaluations. Results: In the micro computed tomography and histological results, the experimental groups 1 and 2 showed more bone formation, remodeling, and calcification than the control group. The new bone formation ratio showed theGroup 2 to be larger than Group 1 at6 and 12 weeks. However, there was no significant difference between the experimental groups 1 and 2 in the new bone formation area, at the 6 and 12 weeks (P>0.05). Conclusion: The PRF-mixed group showed more bone formation than the porcine cancellousbonegroup (TS-GBB), butthere was a no significant difference. The PRF may not lead to enhanced bone healing when grafted with the porcine cancellous bone.

Purpose: Deterioration of consciousness is the most critical problem in patients with fulminant hepatic failure (FHF). Electroencephalography (EEG) is a standard procedure to determine the brain activity in unconscious patients. The bispectral (BIS) index derived from EEG was primarily developed to monitor the depth of unconsciousness. Methods: A prospective study was performed to assess the clinical utility of peritransplant BIS monitoring in 11 fulminant hepatic failure (FHF) patients who were undergoing emergency living donor liver transplantation (LT) with using a right liver graft. All the patients recovered their consciousness after LT. Results: There was a significant correlation between the BIS index values and the derived GCS score (r2=0.634, p <0.001). Timing of eye opening to voice command matched the BIS index value of 64±9.5, which was after 14±9.4 hours passing BIS index of 50. All the patients with endotracheal intubation during the early posttransplant period showed progressive increase of their BIS index, which appeared slightly earlier and more evident than the rise of derived GCS scores. Conclusion: BIS monitoring is a noninvasive, simple and easy-to-interpret method and it also appears to be a useful to assess and predict the recovery of a patient’s consciousness level after LT. Therefore, we concluded that BIS monitoring can be an indispensable component of the peritransplant intensive care for patients with FHF and who require emergency LT.
