Purpose: Pilonidal sinus is a frequent disease that occurs mostly in hairy young men, defined as chronic inflammation and infection of the postsacral sinuses. Wide excision of the affected area is the treatment of choice. Many techniques have been described to cover the defect. However none appears to be the ideal procedure to prevent infection, recurrence, and delayed wound healing. We present the results of an alternative technique that we performed by using partial deepithelized gluteal transposition flap for reconstruction of the defect following wide excision. Methods: From October 2004 to September 2007, we performed the partial deepithelized gluteal transposition flap method on 6 patients. We modified the transposition flap techniques by deepithelialising the medial parts of the flap and burying them under the opposing edge of the flap. The results were compared with previous studies and evaluated regarding duration of surgery, size of defect, hospitalization periods, and complications. Results: All the flaps were healed well with no partial or complete loss of the flap. Hospitalization and immobilization periods were acceptably shortened. Recurrence was not seen. The aesthetic outcome was also satisfactory and all patients were satisfied with the results. Conclusion: The main advantage of our techniques is using healthy tissues to obliterate the dead space, to provide an extra-cushion, and to prevent deep dehiscence. We believe that the partial deepithelized gluteal transposition flap is a good alternative method for treatment of pilonidal sinus.

Objective : To evaluate the clinical outcome of coil embolization for unruptured intracranial aneurysm (UIA) with oculomotor nerve palsy (ONP) compared with surgical clipping. Methods : A total of 19 patients presented with ONP caused by UIAs between Jan 2004 and June 2008. Ten patients underwent coil embolization and nine patients surgical clipping. The following parameters were retrospectively analyzed to evaluate the differences in clinical outcome observed in both coil embolization and surgical clipping : 1) gender, 2) age, 3) location of the aneurysm, 4) duration of the symptom, and 5) degree of ONP. Results : Following treatment, complete symptomatic recovery or partial relief from ONP was observed in 15 patients. Seven of the ten patients were treated by coil embolization, compared to eight of the nine patients treated by surgical clipping (p = 0.582). Patient's gender, age, location of the aneurysm, size of the aneurysm, duration of symptom, and degree of the ONP did not statistically correlate with recovery of symptoms between the two groups. No significant differences were observed in mean improvement time in either group (55 days in coil embolization and 60 days in surgical clipping). Conclusion : This study indicates that no significant differences were observed in the clinical outcome between coil embolization and surgical clipping techniques in the treatment of aneurysms causing ONP. Coil embolization seems to be more feasible and safe treatment modality for the relief and recovery of oculomotor nerve palsy.

Objective: To explore the influence of serum vascular endothelial growth factor (VEGF) level on therapeutic outcome and diagnosis/prognostic value in patients with cervical cancer. Materials and Methods: A total of 37 patients diagnosed with cervical cancer by biopsy were selected and treated with concurrent chemoradiotherapy. Double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) was adopted before treatment to assess VEGF levels, and its relationships with clinicopathological features and short-term therapeutic effects were analyzed. Results: The median VEGF level in 37 patients before treatment was 647.15 (393.35~1125.16) pg/mL. Serum VEGF levels in patients aged <50 years, in International Federation of Gynecology and Obstetrics (FIGO) stage IIIa~IVa, with lymph node metastasis and tumor size >4 cm were significantly increased (P<0.05). The complete remission (CR) rate was 48.7% (18/37), partial remission (PR) rate was 35.1% (13/37), stable disease (SD) rate was 13.5% (5/37) and progressive disease (PD) rate was 2.70% (1/37), so the objective remission rate (ORR) after treatment was 83.8% (31/37). Logistic regression analysis showed that tumor size and serum VEGF level before treatment were independent risk factors affecting the therapeutic outcome, and the higher the level of serum VEGF, the worse the prognosis when tumor size>4 cm. Some 56.8% of patients manifested with myelosuppression, 37.8% with leucopenia, 24.3% with thrombocytopenia, 5.41% with diarrhea, 46.0% with nausea and vomiting, 21.6% with hair loss and 8.11% with hepatic and renal injury during the treatment. Conclusions: Serum VEGF level may reflect the degree of malignancy of cervical cancer and predict therapeutic effect, which is of great importance to cancer diagnosis and prognosis.

PURPOSE. The purpose of this study was to evaluate survival rates and marginal bone loss (MBL) of implants in IC-RPDs. MATERIALS AND METHODS. Seventy implants were placed and used as surveyed crowns in 30 RPDs. The survival rates and MBL around implants based on multiple variables, e.g., position, sex, age, opposing dentitions, splinting, type of used retainer, and first year bone loss, were analyzed. Patient reported outcome measures (PROMs) regarding functional/esthetic improvement after IC-RPD treatment, and complications were also inspected. RESULTS. The 100% implant survival rates were observed, and 60 of those implants showed MBL levels less than 1.5 mm. No significant differences in MBL of implants were observed between implant positions (maxilla vs. mandible; P = .341) and type of used retainers (P = .630). The implant MBL of greater than 0.5 mm at 1 year showed significantly higher MBL after that (P < .001). Splinted implant surveyed crowns showed lower MBL in the maxilla (splinted vs. non-splinted; P = .037). There were significant esthetic/functional improvements observed after treatment, but there were no significant differences in esthetic results based on implant position (maxilla vs. mandible). Implants in mandible showed significantly greater improvement in function than implants in the maxilla (P = .002). Prosthetic complication of IC-RPD was not observed frequently. However, 2 abutment teeth among 60 were failed. The bone loss of abutment teeth was lower than MBL of implants in IC-RPDs (P = .001). CONCLUSION. Class I RPD connected to residual teeth and strategically positioned implants as surveyed crowns can be a viable treatment modality.

Purpose: Grafting with autograft skin remains the most effective method for treating skin defects. When insufficient donor sites are present or patients are afraid of the operation, a skin graft is impossible. Cultured allogenic keratinocytes speed wound healing by providing cover and by producing growth factors and extracellular matrix protein. We report an application of cultured allogenic keratinocytes ($Kaloderm^{(R)}$, Tegoscience, Seoul, Korea) in the treatment of an acute partial thickness skin defect. Methods: From March 2005 to January 2006, 20 patients with a partial thickness skin defect were treated with cultured allogenic keratinocytes. The wound was covered with a sheet of cultured allogenic keratinocytes and ointment with $Bactigras^{(R)}$ gauze. The wound was inspected every two or three days. We regarded completion of epithelialization as wound healing. Results: The mean period between time of injury and time of $Kaloderm^{(R)}$ application was 7.5 days. The time taken from application of $Kaloderm^{(R)}$ to complete closure of the wounds was 7.2 days. Conclusion: In view of the favorable outcome, cultured allogenic keratinocytes are safe and effective biologic dressing materials for use in the treatment of open wounds.

Background: In elbow fracture-dislocation, partial excision of the comminuted radial head fracture that is not amenable to fixation remains controversial considering the accompanying symptoms. This study was undertaken to evaluate the results of radial head partial excision when the comminuted radial head fracture involved <50% of the articular surface in all-arthroscopic repair of elbow fracture-dislocation. Methods: Patients were divided into two groups based on the condition of the radial head fracture. In Group A, the patients had a radial head comminuted fracture involving <50% of the articular surface, and underwent arthroscopic partial excision. Group B was the non-excision group comprising patients with stable and non-displacement fractures. Follow-up consultations were conducted at 6 weeks and at 3, 6, 12, and 24 months after surgery. Results: In all, 19 patients (Group A: 11; Group B: 8) met the inclusion criteria and were enrolled in the study. At the final follow-up, all 19 patients showed complete resolution of elbow instability. No significant differences were observed in the range of motion, visual analogue scale score, and Mayo elbow performance score between groups. Radiological findings did not show any complications of the radiocapitellar joint. However, nonunion of the coracoid fracture was observed in 3 patients (Group A: 1; Group B: 2), without any accompanying instability and clinical symptoms. Conclusions: Considering that the final outcome is coronoid fracture fixation and lateral collateral ligament complex repair for restoring elbow stability, arthroscopic partial excision for radial head comminuted fractures involving <50% of articular surface is an effective and acceptable treatment for elbow fracture-dislocation.

Background The vermilion plays an important role in both the aesthetic and functional aspects of facial anatomy. Due to its structural features, the complete excision of vascular anomalies on the vermilion is challenging, making it difficult to determine the appropriate treatment strategy. Thus, the authors analyzed the results of surgical treatment of vascular anomalies on the vermilion. Methods The medical records of 38 patients with vascular anomalies on the vermilion who underwent surgery from 1995 to 2013 were analyzed. Nine of the cases had an involuted hemangioma, and 29 cases had a vascular malformation; of the vascular malformations, 13, 11, one, and four cases involved were capillary malformations (CMs), venous malformations (VMs), lymphatic malformations (LMs), and arteriovenous malformations (AVMs), respectively. We investigated the surgical methods used to treat these patients, the quantity of surgical procedures, complications and instances of recurrence, and self-assessed satisfaction scores. Results A total of 50 operations were carried out: 28 horizontal partial excisions, eight vertical partial excisions, and 14 operations using other surgical methods. All cases of AVM underwent complete excision. Six cases experienced minor complications and one case of recurrence was observed. The overall average satisfaction score was 4.1 out of 5, while the satisfaction scores associated with each lesion type were 4.2 for hemangiomas, 3.9 for CMs, 4.2 for VMs, 5.0 for LMs, and 4.0 for AVMs. Conclusions It is difficult to completely excise vascular anomalies that involve the vermilion. This study suggests that partial excision focused on correcting the overall contour of the lips is effective and leads to satisfactory results.

The aim of this study was to investigate the early outcome of the taxotere and cisplatin chemoradiotherapy for advanced cervical cancer. Fifty-six cases (FIGO II b to IVa) were divided randomly into two groups: radiotherapy alone (28 cases) and radiation plus chemotherapy (TP) group. There was no difference in radiotherapy between the two groups. The RT+C cases who received TP regimen during the radiation, and DDP once weekly injection of vain, according to 20$mg/m^2$ and taxotere once weekly iv according to 35 $mg/m^2$. These regimens were given for 4~5weeks, and some medicines to control vomiting were available for the RT+C cases. The two groups received an oral medicine MA 160mg every day during the treatment. Regarding early outcome, the complete remission rate was 64.3% and partial remission rate was 35.7% in RT+C. The complete remission rate was 32.1% and partial remission rate was 39.3% in RT. The total response rate and complete remission in the RT+C group were higher than that in the RT group. We conclude that taxotere and cisplatin chemoradiotherapy can improve the early outcome of the advanced cervical cancer, the adverse effects being endurable.

Purpose: There is controversy regarding the cosmetic outcome after accelerated partial breast radiation (APBR). We report the cosmetic outcome from a single-arm prospective clinical trial of APBR delivered using intensity-modulated radiation therapy (IMRT) in elderly patients with stage I breast cancer (BC), using a novel fractionation schedule. Materials and Methods: Forty-two patients aged ${\geq}65$, with Stage I BC who underwent breast-conserving surgery were enrolled in a phase I/II study evaluating a 2-week course of APBR. Thirty eligible patients received 40 Gy in 4 Gy daily fractions. Cosmetic outcome was assessed subjectively by physician/patient and objectively by using a computer program (BCCT.core) before APBR, during, and after completion of the treatment. Results: The median age was 72 years, the median tumor size was 0.8 cm, and the median follow-up was 50.5 months. The 5-year locoregional control in this cohort was 97% and overall survival 87%. At the last follow-up, patients and physicians rated cosmesis as 'excellent' or 'good' in 100% and 91 %, respectively. The BCCT.core program scored the cosmesis as 'excellent' or 'good' in 87% of the patients at baseline and 81% at the last follow-up. The median $V_{50}$ (20 Gy) of the whole breast volume (WBV) was 37.2%, with the median WBV $V_{100}$ (40 Gy) of 10.9%. Conclusion: An excellent rate of tumor control was observed in this prospective trial. By using multiple assessment techniques, we are showing acceptable cosmesis, supporting the use of IMRT planned APBR with daily schedule in elderly patients with early stage BC.
