Phytobezoar is a rare cause of gastro-intestinal tract obstruction. Common sites of phytobezoar are the stomach and small bowel. Naturally, extrahepatic duct phytobezoar is near impossible due to anatomical structure and location such as ampulla of vater, common bile duct and bifurcation of bile duct. Here, we present an extremely rare case of extrahepatic duct phytobezoar that resulted in abdominal pain. We successfully treated the case with extraoperative transenteral endoscopic removal of phytobezoar. For its great rarity and particular treatment approach, we report this case with review of literature.

Renal calcifications are a recognized complication of furosemide therapy in premature infants. Particularly in infants with chronic lung disease, the use of this potent diuretic is associated with hypercalciuria, which may predispose the infant to medullary nephrocalcinosis and renal calculi, We experienced two cases of nephrocalcinosis in very low birth weight infants. One had bronchopulmonary dysplasia, pneumonia, patent ductus arteriosus, ventricular septal defect and congestive heart failure and the other had systemic cytomegalovirus infection with cytomegalovirus pneumonitis and ricket of prematurity. Both patients received a large amount of furosemide. We presented these cases with brief review of literatures.

Heterotopic mesenteric ossification is a very uncommon disorder that is characterized by new bone formation in the mesentery, which does not normally undergo ossification. A 52-year-old female experienced a small bowel obstruction 12 days after a segmental resection of the small bowel following a trauma. A laparotomy was performed 16 days after the initial operation, and a 2 cm hard mass was detected in the small bowel mesentery, with severe fibrous adhesions around the mass, involving the jejunum, which required resection. Postoperatively, the patient developed an intraabdominal abscess, followed by intestinal fistulation. The patient gradually recovered by conservative management, and left hospital 70 days after the first operation. Microscopic examination of the mass showed well oriented trabeculae of the osseous tissue, osteoid formation, with fine calcification and osteoblastic activity, but there was no formation of mature lamellar bone or clear evidence of the "zone phenomenon" that is classically described in heterotopic ossification. These findings appeared consistent with an early stage of heterotopic ossification. The etiology and pathogenesis are unknown; the heterotopic mesenteric ossification was thought to be associated with the trauma (intraabdominal surgery). The previous literature on heterotopic mesenteric ossification is reviewed, and a new case reported.

Most adenocarcinomas of the colorectum arise in a visible benign precursor lesion, the adenoma, which is a monoclonal proliferation of dysplastic nonmalignant epithelial cells. Adenoma-adenocarcinoma sequence has been represented as the predominat pathogenetic pathway. But a small flat depressed colon cancer is characterized by non-polypoid growth pattem with no association of adenomatous tissues, which has tendency to early submucosal invasion and lymph node metastasis even in very small lesion (<10 mm). It supports de novo carcinogenesis of colorectal cancer, although most colorectal cancerarise in pre-existing adenoma. We report a case of small float colon adenocarcinoma arising in normal colonic epithelium rather than adenomatous polyp in familial adenomatous polyposis syndrome.

The purpose of this study was to obtain the basic information for the improvement of dental environment by investigating the presence of methicillin- or vancomycin-resistant Staphylococcus aureus (MRSA or VRSA) isolated from dental health care workers (DHCWs) and environment of the Chosun University Dental Hospital (CUDH) and a private dental clinic (control group). Staphylococcus aureus (S. aureus) was isolated from anterior nares of 42 DHCWs and 38 sites, unit chairs, x-ray devices, computers, etc., at 10 departments of the CUDH and 20 DHCWs and 11 sites at the private dental clinic. S. aureus was isolated on mannitol salt agar plate and confirmed by PCR with S. aureus species-specific primer. Antimicrobial susceptibility test of clinical isolates of S. aureus against several antibiotics including methicillin (oxacillin) was performed by investigating minimum inhibitory concentration (MIC) using broth microdilution assay. In addition, PCR was performed to detect the methicillin- or vancomycin-resistant gene. The data showed that one strain of S. aureus was isolated from DHCWs of the CUDH and three strains of S. aureus was isolated from 3 samples of the private dental clinic, respectively. All of the isolates from the CUDH and the private dental clinic had resistance to penicillin G, amoxicillin and vancomycin and susceptibility to oxacillin and ciprofloxacin. The S. aureus strains were already obtained the resistance to penicillin G and amoxicillin. These results suggest that two dental clinics were under relatively safe environment.

Current acceptable methods of promoting periodontal regeneration are basis of removal of diseased soft tissue, root treatment, guided tissue regeneration, graft materials, biological mediators. Platelet Rich Plasma have been reported as a biological mediator which regulate activities of wound healing progress including cell proliferation, migration, and metabolism. The purpose of this study is to evaluate the possibility of using the Platelet Rich Plasma as a regeneration promoting agent for furcation involvement defect. Five adult beagle dogs were used in this experiment. With intrasulcular and crestal incision, mucoperiosteal flap was elevated. Following decortication with 1/2 high speed round bur, degree II furcation defect was made on mandibular third(P3), forth(P4) and fifth(P5) premolar. 2 month later experimental group were PRP plus bovine bone and bovine bone only. After 4, 8 weeks, the animals were sacrificed by perfusion technique. Tissue block was excised including the tooth and prepared for light microscope with Gomori's trichrome staining. At 4 weeks after surgery, there were rapid osteogenesis phenomenon on the defected area of the Platelet Rich Plasma plus bovine bone group and early trabeculation pattern was made with new osteoid tissue produced by activated osteoblast. Bone formation was almost completed to the fornix of furcation by 4 weeks after surgery. In conclusion, Platelet Rich Plasma can promote rapid osteogenesis during early stage of periodontal tissue regeneration.

As the newly reconstructed nipple tends to be flattened, especially if submitted to pressure, prudent dressings using various protective devices as a physical support against pressure on a new nipple is important. We used a breathing bag connecting tube as a protective device in nipple reconstruction. A breathing bag connecting tube recycled was cut and trimmed at 1cm above the height of the reconstructed nipple. Before stitch out, the newly reconstructed nipple with a local flap was dressed and protected in this way for 10 days after surgery. After stitch out, patients learnt how to manage the new nipple at home. The sole means of nipple dressing was affixing the breathing bag connecting tube with adhesive tape. Two patients had worn the tube for two months with the best compliance. Owing to the soft composition of the tube material, it is possible for a surgeon to have an easy cutting and trimming of the tube at appropriate heights as well as for a patient to show better compliance yielding better results. The cost factor is another advantage.
