Giant condyloma and carcinoma-like condyloma is relatively rare. Although it has histological similarities to condyloma acuminata, it is believed by most authorities to be a clearly defined variant of epidermoid carcinoma. Clinically it is easily mistaken for the more aggressive metastasing epidermoid carcinoma. The legion was first described by Buschke in the German literature in 1896. as a varient of condyloma acuminata. A case of malignancy of the penis which have apparently been transformed from giant condyloma acuminata of the penis are herein presented with review of literature.

BACKGROUND: Most of nonrebreathing circuits were used for pediatrics, not for adults and the high flow of fresh gas and specially designed valve or lever should be needed. The current study was designed to compare between one corrugated tube(universal FTMcircuit) and two corrugated tube in patients with oral and maxillofacial surgery under general anesthesia. METHODS: Twenty adults undergoing oral and maxillofacial surgery were anesthetized with enflurane- N2O-fentanyl after radial arterial cannulation. Under the condition with stable vital signs, ventilator was setted with tidal volume 10ml/kg, respiratory rate 11 breaths/min using two separate limbs(expiratory and inspiratory limbs) and one corrugated tube of anesthesia machine. Mean arterial pressure, heart rate, saturated pulse oxygen, end tidal carbon dioxide, peak inspiratory oxygen, arterial blood gas analysis were measured at 15, 30min during the use of each circuit. RESULTS: There were no differences of mean arterial pressure, heart rate, end tidal carbon dioxide, saturated pulse oxygen. peak inspiratory presssure and arterial blood gas analysis between 2 circuits during mechanical ventilation. CONCLUSIONS: Universal FTMcircuit of single limb could substituted for the two corrugated tube, especially in patients with oral and maxiolofacial surgery.

To evaluate the effectiveness of centralizing device, three groups of patients on whom cemented total hip arthroplasty with three types of implant was performed respectively were analyzed and compared; SL stems without centralizing device were used in Group I, Interlok stems with central sleeve in Group II, and MS-30 stems with distal centralizer in Group III .The size of each group was 20. Cement mantle thickness, the amount of displacement of stem tip, and axis alignment of femoral stem on A-P radiograph checked at 2 weeks after operation were assessed. More optimal cement mantle thickness (3~6mm) was achieved in Group II (P=0.046) and Group III (P=0.01) than in Group I. Centralizing effect of the distal femoral stem in the intramedullary canal was significantly better (P<0.05) in Group III ( 4.55% ) than in Group I (11.60%) and Group II (12.35%). Neutral alignment of femoral stem was achieved in 15% of Group I, in 90% of Group II, and in 95% of Group III. Compared to stem without centralizing device, cemented femoral stem with distal centralizer resulted in 1) significantly more centralized distal femoral stem, 2) significantly more neutrally aligned femoral stem,and 3) significantly more optimal cement mantle thickness at zone V. Compared to stem without centralizing device, cemented femoral stem with central sleeve resulted in 1) significantly more neutrally aligned femoral stem, and 2) significantly more optimal cement mantle thickness at zone VI.

This paper reports two cases of schwannomas arising from the oral cavity. One is an intraoral ancient schwannoma located at the left cheek, which evolved over a period of 13 years. The tumor was a well-demarcated buccal mass, which was located in the left lower first premolar area, with an obliterated the buccal vestibule, leaving the overlying mucosa intact. The second case was a central intraosseous schwannoma located from the left lower 1st molar periapical area to the left 3rd molar periapical area. Pathologically, the first mass was composed of the spindle shaped tumor cells with wavy nuclei beneath the fibroconnective tissue of the gingiva but second case mass was not. Occasional nuclear pleomorphism was observed but mitosis or necrosis was absent. There were Antoni A and B areas along with strong, diffuse staining with the S-100 protein. Ancient schwannomas were diagnosed. Schwannoma is a slow-growing benign tumor, and an ancient schwannoma that shows cellular atypism is a variant of a schwannoma caused by purely degenerative changes. To date, only limited cases of ancient schwannomas in the oral cavity have been reported.

Focal osteoporotic bone marrow defect (FOBMD) is a radiolucent area corresponding to the presence of hematopoietic tissue rarely found in the jaws. FOBMD is most commonly located in the mandibular edentulous posterior area of a middle-aged female. From November 2011 to November 2012, we experienced three cases involving removal of implants that had accidentally fallen into the FOBMD area. All patients happened to be female, with a mean age of 54 years (range: 51-60 years). One case involved hypoesthesia of the lower lip and chin, while two cases healed without any complication. Displacement of an implant into the FOBMD area is an unusual event, which occurs rarely during placement of a dental fixture. The purpose of this study was to report on three cases of FOBMD and to provide a review of related literature.
