Conjoined twins occur when there is imcomplete fission of the inner cell mass later at approximately 13 to 15 days after fertilization. The earlist case in the literat.ure appears to be that of the Biddenden Maids who were born in England in 1100. since then over two hundred cases of successful separation were reported on literature. And also successful separation cases were reported by Seung et al.(1991) in Korea. Conjoined twins occur between one in 50,000 to 100,000 births but real incidence is one in 200,000 because two thirds are stillbirth or died immediately after birth. The conjoined twins are not associated with maternal age, race or family history and 70 % of them are females. We experienced a case of conjoined twins with omphalopagus and performed surgical separation. A brief review of related literatures was done.

Kasabach-Merritt syndrome is the association of thrombocytopenia, disorder of coagulation, spontaneous bleeding and enlargement of a hemangima or extensive hemangiomatosis, which can be often life threatening. We experienced a three years-old girl with suddenly enlarging hemangioma of right cheek, complicated by severe thrombocytopenia, consumptive coagulopathy and hemorrhagic cystitis. Generalized petechia and ecchymosis were noted on the overlying skin of hemangioma, trunk and extremities. But the study of MRI and angiography, hypevascular was located within the right masseter muscle extending to temporalis muscle and anterior to parotid gland. So selective embolization with PVA (polyvinyl alcohol) was performed through the distal branch of internal maxillary artery and facial artery. She was medicated with oral corticosterioid for 3 weeks. After embolizationn, blood flow to hemangioma and facial swelling were markedly decreased. Patient was followed up for 7 years and she showed normal contour of face and no bleeding diathesis.

Accessory auricle is a relatively rare congenital anomaly arised from the abnormaI development of the auricular tubercles or from the tissues surrounding the second, third and fourth branchial clefts. Clinically this anomaly is a small akin-colored tag or nodule, soft and globular or cartilaginous consistency on or near the tragus along a line drawn from the tragus to the angle of the mouth or along the anterior margin of the sternomastoid muscle. The lesion is usually solitary and located in the preauricular area but may be multiple and rarely bilateral. We present a typical caae of accessory auricles in 4-day-old female infant. The patient had two skin-colored firm nodules on the left preauricular area and well pedunculated one on the Ieft buccal area near the angle of the rnouth. Histopathologic find.ings showed numerous pilosebaceous units, abundant subcutaneous fat and cartilage tissue in the center of the lesion.

Serine protease activity of high temperature requrement 2 (HtrA2) is essential for promoting cell death, as well as for protecting against cellular stresses. An X-ray crystallographic study described the formation of a pyramid shaped homotrimer that is a proteolytically competent form of HtrA2; however, little is known about effects of the trimeric structure of HtrA2 on the natural substrates. In this study, we generated the HtrA2 protein that has a single point mutation at the homotrimerization motif to assess relationship between structure and the proteolytic activity of HtrA2 on its substrates. Using gel filtration, a native gel electrophoresis system, and a co-precipitation assay, we confirm that phenylalanine 149 in HtrA2 is a crucial determinant for the formation of the HtrA2 homotrimeric structure. Moreover, we described that the HtrA2 monomeric form abolished not only autoproteolytic activity, but also the proteolytic activity against XIAP (X-linked inhibitor of apoptosis protein) known as the HtrA2 substrate. Taken together, the results indicate that the homotrimeric structure of HtrA2 is required for executing its serine protease activity.

BACKGROUND: Genital skin cancer is a potential side effect of phototherapy. Development of genital skin cancer lowers a patient's quality of life. However, there are no standards for genital protection during phototherapy. OBJECTIVE: This study was designed to find adequate materials for genital protection. METHODS: Eight common materials for genital protection were placed over an ultraviolet (UV) meter that was irradiated with UVA and narrowband UVB phototherapy units. The percentage of blocked UV was measured. RESULTS: White and black cotton underwear, white and black polyester underwear, and surgical drapes did not allow the transmission of UVA and narrowband UVB light. But a surgical mask allowed about 15% transmission of UV light. CONCLUSION: These results suggest that white and black cotton underwear, white and black polyester underwear and surgical drapes provide sufficient UV protection.

Dental caries is the most common chronic disease in the dental field. Streptococcus mutans (S. mutans) is the most important bacteria in the formation of dental plaque and dental caries. In a previous study, we confirmed that the essential oil of Chrysanthemum boreale has antibacterial activity against S. mutans. Alpha-pinene is one of the major chemical components of Chrysanthemum boreale essential oil. In the present study, we investigated the inhibitory effects of α-pinene on cariogenic properties such as growth, acid production, biofilm formation, and bactericidal activity on S. mutans. Alpha-pinene at a concentration range of 0.25-0.5 mg/mL significantly inhibited the growth of S. mutans and acid production of S. mutans. Biofilm formation was significantly inhibited at < 0.0625 mg/mL α-pinene, similar to the data from scanning electronic microscopy. Under confocal laser scanning microscopy, the bacterial viability was decreased by α-pinene in a dose-dependent manner. These results suggested that α-pinene may be a useful agent for inhibiting the cariogenic properties of S. mutans.

Usually, the papilla of Vater is located in the midportion or the distal half of the descending duodenum. Isolated cases of common bile duct termination in other sites, including the fourth portion of the duodenum, the pyloric ring, the duodenal bulb and the stomach, have been reported. A case is here in reported involving abdominal pain in the right upper quadrant area, in which an ERCP demonstrated an anomalous termination of the common bile duct and pancreatic duct into the duodenal bulb separately. This anomaly was associated with a bile duct dilatation and single common bile duct (CBD) stone. Trial of CBD stone removal during an ERCP failed. The patient's condition improved after a cholecystectomy and choledochojejunostomy.
