Benign odontogenic neoplasms are rare, but malignant odontogenic neoplasms are extremely rare. The majority of malignant epithelial neoplasms occurring in the jaws are the result of metastasis from distant primary neoplasms of direct invasion from contiguous carcinoma of the oral mucosa, sinus mucosa, salivary gland or skin. A few remaining primary intraosseous carcinoma of the jaw are presumed to be of mostly odontogenic origin since epithelial remnants of odontogenesis are numerous in the maxilla arts mandible. Although calcifying odontogenic cyst(COC) is a well-established pathologic entity, it has been recognized that there is an odontogenic neoplasm with histologic features similar to the COC(malignant epithelial odontogenic host cell tumor; EOGCT) that has been diagnosed as COC. Some authors have reported previously in the literature describing malignant EOGCT. We experienced one case of malignant EOGCT with aggressive growth pattern and histologic features strongly implying its malignant potential. The lesion was excised by anterior mandibular resection, total 1 resection of the tongue and bilateral functional neck dissection. The tongue was reconstructed by using the infrahyoid muscle neurovascular island flap and neurovascular radial forearm free flap. The mandible was reconstructed by using the osteocutaneous fibular free flap.

Laparoscopic repair using mesh is a standard technique for ventral hernia repair. Complications of laparoscopic ventral hernia repair increase according to the increment of laparoscopic repair. Subcutaneous emphysema and mesh infection are major complications of laparoscopic repair of ventral hernia. The principle of management of infection is removal of a foreign body. However, in the case of repair with mesh, removal of infected mesh induces recurrence of hernia. Preservation of mesh is the best option for treatment of infected mesh. We have experienced treatment without removal of mesh in a case of infected subcutaneous emphysema after laparoscopic ventral hernia repair. The infection spread slowly to mesh and seroma. Drainage and debridement of infected tissue and evacuation of infected seroma resulted in healing of the infection without removal of mesh.

Local or distant flap surgery has been applied in the soft tissue defect area where bone and tendon are exposed, but there are many pitfalls in these surgeries including limitation of donor site selection, as well as functional and aesthetic dissatisfaction of the donor and recipient site. So these problems have facilitated the development and study of skin substitute (artificial dermis). The history of artificial skin began in the 1980s with the invention of Stage I membrane by Yannas and Burke. Since then it has been developed and applied to chinical cases of extensive burn injury and soft tissue defect. In 1989, and artificial dermis (Terudermis) composed of fibrillar collagen and heat denaturated atelocollagen was developed by Konish. It has the advantage of allowing early-incorporation of cellular and vascular components into its collagen sponge, as well as dehydrothermal cross-linking, which is very weak. This study included 18 consecutive cases which underwent application of artificial dermis on bone and tendon from January 1997 to November 1998. The exposed areas were the result of trauma in 10 cases, postoperative complications in 2 cases, and other causes in 6 cases. The follow-up period ranged from 3 months to 18 months, averaging 11 months. A week after wound debridement and Terudermis application, neovascularization had begun and granulation tissue appeared aften 2-3 weeks. Then the split or full -thickness skin graft was secondarily applied resulting in the production of sufficient skin. In conclusion, Terudermis application to an area of exposed bone and tendon is a very useful method, especially when primary local or distant flap surgery cannot be used. This method is very simple, convenient and reliable.

Emphysematous urinary tract infection is a rare, life-threatening necrotizing infection characterized by gas generation, and usually occurs in patients with diabetes and/or urinary tract obstruction. We herein report a unique case of emphysematous renal infection occurred in. an old diabetic man with renal cell carcinoma. This case suggests that renal cell carcinoma should be also considered a rare cause of emphysematous renal infection showing mass contour.

PURPOSE: The aims of this study were to assess the oncologic safety of laparoscopic colorectal surgery compared to that of conventional open surgery and to compare the disease-free survival (DFS) rates between laparoscopic and open colorectal surgery for radical treatment of colorectal cancer. METHODS: From January 2001 to December 2005, 583 patients underwent laparoscopic or conventional open surgery. To address only radical treatment of colorectal cancer, we excluded subjects who had undergone emergency or palliative operation. Four hundred ninety patients were identified for this study. The laparoscopic (LG) and open group (OG) had 74 and 166 patients, respectively, for colon cancer, and 92 and 158 patients, respectively, for the rectal cancer. RESULTS: No difference was noted in the lengths of the distal margins of the resected bowels between the LG and the OG for rectal cancer (P>0.05). In addition, no significant difference was found in DFS rates between the LG and the OG for both colon and rectal cancer (P>0.05). CONCLUSIONS: The laparoscopic technique does not seem to present any disadvantages and is safe and feasible for the treatment of colorectal cancer. No difference was found between laparoscopic and open surgery in terms of DFS for colorectal cancer.

Bartter's syndrome is a rare tubular disorder characterized by hypokalemic, hypochloremic metabolic alkalosis, hyperreninemic hyperaldosteronism, hyporesponsiveness to pressor agents, and juxtaglomerular apparatus hyperplasia. We report here a case of Bartter's syndrome in a 5 month-old male infant who improved with potassium supplements. In addition to a case report, brief review of related literatures was done.

Pulmonary arterial hypertension is caused by vascular remodeling including muscularization of arteries, loss of small precapillary arteries, and formation of neointima and plexiform lesion, resulting in a progressive increase in pulmonary vascular resistance. About 70% of heritable pulmonary arterial hypertension and 10% to 40% of idiopathic pulmonary arterial hypertension patients possess mutations in bone morphogenetic protein receptor, type 2 (BMPR2), which is a type II receptor of TGF-beta superfamily. Very rarely, mutations in another receptors of TGF-beta superfamily, activin-like kinase-type 1 (ALK1) and endoglin (ENG) are found in pulmonary arterial hypertension patients with hereditary hemorrhagic telangiectasia. Genetic screening is useful to identify family members who are mutation carriers in heritable pulmonary arterial hypertension families.
