Purpose: In developed countries, vesicovaginal fistula occur from various pelvic operations including total hysterectomy, leading to urinary leakage and incontinence. Although various methods have been proposed for adequate tissue coverage in fistula repair, the surgical treatment of is not simple and still controversial. We report a case of neobladder-vaginal fistula repair using modified Martius fat pad flap. Methods: A 62-year-old female patient underwent radical cystectomy with total abdominal hysterectomy and neobladder formation due to invasive bladder tumor 5 years ago. For 3 years following the operation, urine leakage was observed. Exploration demonstrated neobladder-vaginal fistula and primary repair including fistulectomy and direct closure was performed. Urinary incontinence relapsed 2 years after primary repair, and after demonstrating the recurrence of fistula on urography, repair of recurrent fistula was performed. After dissection of vagina and neobladder and closure of fistula by urologic surgeon, fibroadipose flap was elevated, rotated and advanced through the tunnel at vaginal sidewall, and interpositioned to the fistula site between neobladder and vagina. Results: There was no acute complication after the surgery and urethral catheter was extracted on the 8th day after the operation. During six month follow-up period after the operation, there is no clinical evidence of fistula recurrence. Conclusion: From our clinical experience and literature review, we think Martius fat pad flap is a useful technique in management of neobladder-vaginal fistula, for it provides enough vascularity, major epithelization surface and better lymphatic drainage, and also prevents overlapping of vesical, vaginal suture lines at the same time.

Background The medial canthus is an important area in determining the impression of a person's facial appearance. It is composed of various structures, including canthal tendons, lacrimal canaliculi, conjunctiva, the tarsal plate, and skin tissues. Due to its complexity, medial canthal defect reconstruction has been a challenging procedure to perform. The contralateral paramedian forehead flap is usually used for large defects; however, the bulkiness of the glabella and splitting at the distal end of the flap are factors that can reduce the rate of flap survival. We reconstructed medial canthal defects using ipsilateral paramedian forehead flaps, minimizing glabellar bulkiness. Methods This study included 10 patients who underwent medial canthal reconstruction using ipsilateral paramedian forehead flaps between 2010 and 2012. To avoid an acute curve of the pedicle, which can cause venous congestion, we attempted to make the arc of the pedicle rounder. Additionally, the pedicle was skeletonized from the nasal root to the glabella to reduce the bulkiness. Results All patients had basal cell carcinoma, and 3 of them had recurrent basal cell carcinoma. All of the flaps were successful without total or partial flap loss. Two patients developed venous congestion of the flap, which was healed using medicinal leeches. Four patients developed epiphora, and 2 patients developed telecanthus. Conclusions Large defects of the medial canthus can be successfully reconstructed using ipsilateral paramedian forehead flaps. In addition, any accompanying venous congestion can be healed using medicinal leeches.

Purpose: To evaluate the clinical outcome of high-dose-rate (HDR) interstitial brachytherapy (IBT) in patients with oral cavity cancer. Materials and Methods: Sixteen patients with oral cavity cancer treated with HDR remote-control afterloading brachytherapy using $^{192}Ir$ between 2001 and 2013 were analyzed retrospectively. Brachytherapy was administered in 11 patients as the primary treatment and in five patients as salvage treatment for recurrence after the initial surgery. In 12 patients, external beam radiotherapy (50-55 Gy/25 fractions) was combined with IBT of 21 Gy/7 fractions. In addition, IBT was administered as the sole treatment in three patients with a total dose of 50 Gy/10 fractions and as postoperative adjuvant treatment in one patient with a total of 35 Gy/7 fractions. Results: The 5-year overall survival of the entire group was 70%. The actuarial local control rate after 3 years was 84%. All five recurrent cases after initial surgery were successfully salvaged using IBT ${\pm}$ external beam radiotherapy. Two patients developed local recurrence at 3 and 5 months, respectively, after IBT. The acute complications were acceptable (${\leq}grade$ 2). Three patients developed major late complications, such as radio-osteonecrosis, in which one patient was treated by conservative therapy and two required surgical intervention. Conclusion: HDR IBT for oral cavity cancer was effective and acceptable in diverse clinical settings, such as in the cases of primary or salvage treatment.

Background: L-asparaginase (ASNase) is commonly used in the treatment of acute lymphoblastic leukemia (ALL) and natural killer (NK)/T-cell lymphoma. This study was designed to describe the incidence of toxicity associated with ASNase in Asian adults. Secondary objectives were to investigate the management and impact of toxicity on subsequent ASNase use, and to compare the actual management against current recommendations. Materials and Methods: In this retrospective, multi-center, observational study, Asian patients ${\geq}18$ years old who received ${\geq}1$ dose of the native E. coli ASNase from 2008 to 2013 were included. Patients were excluded if they did not receive ASNase. Endpoints of this study were development of specific toxicities, whether ASNase was discontinued or re-challenged, and developmentg of recurrent toxicity. All data analyses were performed using SPSS version 20.0. Results: A total of 56 patients were analyzed. Mean (${\pm}SD$) age was 36.2 (${\pm}15.2$) years old, with 62.5% being males, 55.4% with ALL and 28.6% with NK/T-cell lymphoma. Hypersensitivity (12.5%) was associated with the highest incidence of toxicity (6 out of 7 patients had Grade 3 and 4 toxicity), followed by 10.7% for hepatic transaminitis, 3.6% for non-CNS thrombosis and 1.8% each for hyperbilirubinemia and pancreatitis. Hypersensitivity recurred in the 3 patients who were re-challenged with E. coli ASNase. Conclusions: ASNase is associated with a wide range of toxicities, with hypersensitivity being the most commonly observed among Asian adult patients.

A 34-year-old man with ACL total rupture due to slip down injury, had received ACL reconstruction using autogenous hamstrings tendon with cross-pin femoral fixation. Postoperative course was as usual. But postoperative 3 months later, he complained posterolateral knee pain, recurrent effusion and mild instability. He was managed repeatitive aspiration and nonsteroid antiinflammatory drugs but was failed to relieve symptoms & signs. In CT scans, perforation of posteromedial femoral cortex of lateral femoral condyle was found. In second look arthroscopy, two pieces of broken femoral cross pin were found in between tibiofemoral Joint which was badly injured cartilage. We considered malposition of pins was the main cause of failure. We propose that femoral tunnel must be made more acute angle and femoral cross-pin guide must be positioned more external rotation 10-20 degree than transepicondylar axis made confirm the cross-pin tunnel position in order to avoid posterior cortex perforation and early failure.

Background: Defective or immature antibody responses to pathogens in children may explain the increased susceptibility to acute otitis media. However, there is no study in Korea patients whether a correlation exists between otitis media with effusion and the levels of serum immunoglobulins, IgG subclasses, IgA, IgM and IgE. Methods: 45 children with otitis media with effusion more than 4 episodes in 12 months or 3 episodes in 6 months, 62 children with otitis media with effusion less than 3 episodes in 12 months and 102 children for control group took part in the study at the Department of Otorhinolaryngology of the KyungHee University from May 2004 to Feburary 2007. Serum immunoglobulin levels were determined by nephelometry. And then the relationship between otitis media with effusion and serum immunoglobulin level was evaluated. Results: In otitis media prone group, serum IgG1, IgG2, IgG4, and IgA level was lower than those level of control group, it was significantly decreased (p<0.05). In otitis media group, serum IgA, IgE, and IgG4 level was lower than those level of control. But it was not statistically significant (p>0.05). Conclusion: Lower immunoglobulins in children with otitis media with effusion suggest a generalized decreased antibody responses. Lower levels of serum IgG1, IgG2, IgG4, and IgA may be related with chronicity or intractability of otitis media with effusion.

Objectives : Vocal fold augmentation by injectable material under direct visual control is an easy and simple operation. However, when autologous fat or bovine collagen is used, resorption creates a problem. And autologous fascia is debating about absorption now days. This study is to evaluate the histology of minced and injected autologous auricular cartilage and fat graft in the augmentation of unilateral vocal fold paralysis using a canine model. Methods : Nine dogs were operated. At first, a piece of auricular cartilage was harvested from ear and minced into tiny chips with a scalpel. And also, a piece of fat tissue was harvested from inguinal area and minced into tiny chips with a scalpel. Cutting off a section of the recurrent nerve paralyzed the right vocal fold. The minced cartilage and fat-paste (0.2ml) was injected using a pressure syringe into the paralyzed thyroarytenoid muscle under direct laryngoscopy. Two animals were sacrificed at 3 days, three at 3 weeks, two at 3 months, one at 6 months, one at 12 months. Each dog underwent laryngectomy and serial coronal sections of paraffin blocks from the posterior part of the vocal fold were made. Results : There was no significant complication perioperatively and during follow-up. There was acute inflammatory findings in the graft at 3 days and 3 weeks. The injected cartilage remained in the larynx until 12 months. Conclusion : The autologous auricular cartilage graft is well tolerated and may be very effective material for volumetric augmentation on paralyzed vocal cord.

A 6-year-old boy with underlying hemolytic anemia of unknown etiology, atopic dermatitis, and recurrent urticaria visited our hospital because of acute respiratory failure induced by influenza A. Despite mechanical ventilation after endotracheal intubation along with inhalation of nitric oxide, respiratory acidosis and hypoxemia persisted. Veno-venous extracorporeal membrane oxygenation (VV ECMO) insertion was performed to provide respiratory support. After performing flexible bronchoscopy, we found that thick mucus plugs were obstructing the right bronchus intermedius and the upper lobe orifice. After bronchial washing and removal of the plugs, we were able to wean the patient off VV ECMO and transfer him to the general ward. He was discharged without any neurologic or pulmonary sequelae.

Osteomyelitis is an infection of bone or bone marrow, caused by pyogenic bacteria or mycobacterium. Osteomyelitis can be acute or chronic, inflammatory process of the bone and its structures. Chronic osteomyelitis will result in variable sclerosis and deformity of the affected bone. With an infection of the bone, the subsequent inflammatory response will elevate this overlying periosteum, leading to a loss of the nourishing vasculature, vascular thrombosis, and bone necrosis, resulting occasionally in formation of sequestra. These become areas that are more resistant to systemic antibiotic therapy due to lack of the normal Havesian canals that are blocked by scar tissue. At this aspect, not only systemic antibiotic therapy, but also surgical debridement maybe required to remove the affected bone and prevent disease propagation to adjacent areas. We experienced a patient who diagnosed tongue cancer and underwent wide partial glossectomy few years before, with an ulcerative lesion around right retromolar trigon. We diagnosed cancer recurrence because PET indicated hot uptake on mandible which was nearby previous tongue tumor site. The patient received hemiglossectomy via paramedian mandibulotomy, partial mandibulectomy and fibula osteocutaneous free flap reconstruction. But final diagnosis was mandible osteomyelitis on pathology report. Here, we present the case with a review of the related literatures.
