Fibro-osseous pseudotumor is an extremely rare benign lesion which is fast-growing and painful. It is often misdiagnosed as a malignancy, but it is a noninvasive entity and can be cured by simple resection. We report a case of fibro-osseous pseudotumor of the distal phalanx of great toe in 20-year-old female patient who present with painful mass.

A secondary cleft lip nasal deformity can be corrected by many procedures including central lip tissue transfer, forked flap, nasal floor and alar base advancement, nasal skin flaps and composite graft. These procedures have been applied for many years, but each one has some conspicuous residual problems. We propose triple V-Y advancement flaps, which we have performed on 13 secondary cleft lip and nasal deformity patients over the past 6 years. The W-shaped triple reverse V-shaped incision easily exposed the alar cartilages. We made the advancement and rotation of the nasal skin flap to lengthen the columella and project the nasal tip. Postoperatively, the columella length and nasolabial angle were found to be increased by an average of 3.7 mm and 42 degrees, respectively. In lateral view, a relatively natural nasal line was achieved. The scar in the nasal tip posed few problems. This procedure should be useful for the correction of the secondary cleft lip nasal deformity.

BACKGROUND: Treatment of pulmonary metastasis from urothelial cell carcinoma has been mostly palliative chemotherapy and the role of pulmonary metastasectomy has not been investigated much. MATERIALS AND METHODS: This study is a retrospective interim review of pulmonary metastasectomy from urothelial carcinoma at single institution between 1998 and 2010. Overall 16 patients underwent pulmonary metastasectomies. RESULTS: There was no postoperative complication or hospital mortality. Mean hospital stay was 6 days. Overall and disease-free 5-year survival were 65.3% and 37.5%, respectively. CONCLUSION: In selected patients with pulmonary metastasis from urothelial carcinoma, surgical treatment is feasible and could contribute to long-term survival in selected patients.

The purpose of this study was to aid in the prediction of tumor cell tolerance to radiotherapy and/or chemotherapy. For this study, cell surviving curves were obtained for human squamous cell carcinoma KB cell line after radiation exposure and/or administration of antitumor drugs. 2, 4, 6, 8 10Gy were irradiated at a dose rate of 210Gy/min using 60Co Irradiator ALDORADO 8. After irradiation, KB cell lines(3*104cells/ml) were exposed to 2 /ml of bleomycin ir cisplatin for 1 hour. The viable cells were determined by MTT assay for each radiation dose and/or each drug at the 4th day. And they were compared to control values. The obtained results were as follows ; 1. The slope of the surviving curve after irradiation of 2, 4, 6, 8, 10Gy on KB cell line was relatively steep. 2. There was no significant difference between ths cytotoxicity of bleomycin compared to control group. But, there was significant difference between the cytotoxicity of cisplatin compared to control group. And the cytotoxicity of cisplatin was greater than that of bleomycin on KB cell line. 3. There were dignificant differences of surviving fractions after irradiation of 2Gy and 10Gy with 2 /ml of bleomycin compared with the groups of irradiation only on KB cell line. 4. There were significant differences of surviving fractions after irradiation of 2, 4, 6, 8, 10Gy with 2 /ml of cisplantin compared with the groups of irradiation only on KB cell line. 5, There was significant difference of surviving fraction between groups after irradiation of 10Gy with 2 /ml of bleomycin and cisplatin.

To investigate the protective effect of hyaluronic acid on the corneal endothelial damage induced by perfusion with hydrogen peroxide, rabbit corneas were mounted in the in vitro dual-chambered specular microscope and perfused with glutathione-bicarbonate-ringer(GBR) solution for one hour, and test agents for additional two hours. Test agents were hydrogen acid(0.01%). and chondroitin sulfate(0.04%). Corneal thickness was measured every 15 minutes during the perfusion and a corneal swelling rate was calculated by linear regression analysis. At the end of perfusion, corneas were fixed for transmission electron microscopy(TEM). Hydrogen peroxide(0.5mM) caused marked corneal swelling white 0.25mM did not(65.95+/-8.03 vs. 6.69+/-2.58micrometer/hr). Healon prevented the H2O2 induced corneal swelling(15.85+/-2.99micrometer/hr) and maintained the endothelial ultrastructures. Viscoat enabled the corneas to deswell(-35.90+/-18.04micrometer/hr). Hyaluronic acid(0.01%) and catalase(15000U) also prevented corneal swelling induced by hydrogen peroxide(9.52+/-3.61, 4.61+/-0.99micrometer/hr respectively), and maintained the endothelial ultrastructure, however 0.04% chondroitin sulfate showed marked corneal swelling(71.73+/-2.12micrometer/hr). The results of this study showed that Healon and Viscoat containing hyaluronic acid could protect corneal endothelial cells from hydrogen peroxide.

The free flaps have been used for reconstruction of the head and neck because of their superior results comparing with other types of flaps. Among them, radial forearm free flap has many advantages, its thinness, pliablilty, long vascular pedicle, large sensory flap, and compound flap including tendons and bone. We report 28 cases of head and neck reconstruction with radial forearm free flap between March 1991 and March 1997. Patient's age ranged from 21 to 76 years(mean 50.5 years). There were 23 men and 5 women. Mean follow-up period was 14 months. The most common cause was malignant tumor of the head and neck, especially squamous cell carcinomas(18 cases). We used this flap to reconstruct the oral cavity in 13 cases, the hypopharyngoesophagus in 6 cases, external surface of the head and neck in 7 cases, and the orbit in 2 cases. All of these flaps survived without complication. Two cases of fistula developed, in which forearm flaps were used for tongue and hypopharyngoesophageal reconstruction, and they were treated with conservative manners. Partial losses of skin graft at donor site of the forearm developed in 3 cases. They healed with split-thickness skin graft or local flap. The function of reconstructed upper aerodigestive tract and eye socket was good. The cosmetic result was not good in cases of reconstruction for external surface of the face with this flap, but it was better than other free flaps. So, we concluded the radial forearm free flap is available for reconstruction of the head and neck.
