We report a case of myiasis on the left submandibular area after radiation therapy for squamous cell carcinoma. A 77-year-old man visited our hospital, 7 weeks after complicating a course of radiation therapy, had a 7cm diameter necrotic ulcer on the left submandible. The margin of the lesion were undermined by numerous interlinking passages containing 20 maggots. The maggots were removed by simple extraction and were identified as Calliphoridae Lucilia. The probable origin of the myiasis in this case was attributed to poor environmental condition and general weakness of the patient. Oppotunistic cutaneous myiasis can be prevented by protecting open wounds from flies, wound should not be left without a covering capable of excluding flies, especially in the summer month.

OBJECTIVE: Oocyte-specific homeobox 4 (Obox4) is preferentially expressed in oocytes and plays an important role in the completion of meiosis of oocytes. However, the Obox4 expression pattern has not been reported yet. In this study, we investigated the subcellular localization of Obox4 using a green fluorescent protein (GFP) fusion expression system. METHODS: Three regions of Obox4 were divided and fused to the GFP expression vector. The partly deleted homeodomain (HD) regions of Obox4 were also fused to the GFP expression vector. The recombinant vectors were transfected into HEK-293T cells plated onto coated glass coverslips. The transfected cells were stained with 4',6-diamidino-2-phenylindol and photographed using a fluorescence microscope. RESULTS: Mutants containing the HD region as well as full-length Obox4 were clearly localized to the nucleus. In contrast, the other mutants of either the N-terminal or C-terminal region without HD had impaired nuclear localization. We also found that the N-terminal and C-terminal of the Obox HD contributed to nuclear localization and the entire HD was necessary for nuclear localization of Obox4. CONCLUSION: Based on the results of the present study, we demonstrated that the intact HD region of Obox4 is responsible for the nuclear localization of Obox4 protein in cells.

Residual dysplasia is common in spite of early treatment of developmental dysplasia of the hip and often requires a harness or femoral/ acetabular surgery. Operative treatment is roughly divided into two categories: reconstructive and salvage; but the reconstruction such as re-directional osteotomy of the acetabulum should always be considered first. Operative treatment consists of osteotomy on femur or acetabulum, or both. Before the surgery, thorough evaluation of the patient is necessary to select appropriate operation. Avascular necrosis is one of the most catastrophic complications, which is often seen in delayed diagnosis or surgically treated patients.

PURPOSE: Medical treatment of Peyronie's disease with tamoxifen has been initially proposed as acting upon the early phase of the disease. As recent reports show no significant benefit of tamoxifen, we review the long term results of tamoxifen treatment of Peyronie's disease. MATERIALS AND METHODS: Time to progression during tamoxifen treatment of patients showing acute disease and chronic disease was compared. The acute phase was identified by pain during erection. Progression was defined as enlargement of plaque size or appearance of calcification. RESULTS: The average treatment duration was 15.9+/-13.8 months (range: 3 to 48 months). The median time to progression was 7 months for acute patients and 20 months for chronic patients. Eighty percent of patients in the acute phase showed relief of pain; however, overall progression was 72.1% (78.0% for acute, 66.7% for chronic). Patient history, comorbidities, serum testosterone or initial plaque characteristics, and severity of curvature were not predictive of disease progression. CONCLUSIONS: Tamoxifen showed no significant benefit in slowing the progression of Peyronie's disease in the acute phase over the chronic phase. Peyronie's disease continued to progress, though at a dampened rate for patient's in the chronic phase.

PURPOSE: To see the stability and error in the diffusion-weighted magnetic resonance (MR) imaging technique in the experimental models and to observe the signal intensities in the early cerebral lesions of the animal models. MATERIALS AND METHODS: Diffusion coefficients of acetone and distilled water were measured by diffusion-weighted MR image and were compared with actual values. Differentiation of diffusion from perfusion were done at the resin flow phantom. The signal intensities caused by early parenchymal changes were measured in normal, hypovolemic, and embolic, and dead animal models by using diffusion-weighted image and compared with pathoIogic finding and vital staining. RESULTS: Diffusion coefficients of acetone and distilled water were 4.48 x 10-3 and 2.72 x 10-3 which were very close to the actual values. Diffusion-weighted MR image obtained at flow phantom was not affected by flow (perfusion) at the 100-400 of b-factor range. Animal study done at that b-factor range revealed a significant signal difference between the left and right sides only at the embolic model induced by polyvinyl alchol particles (p<0.05). These changes were not detected in microscopic finding but could be identified in vital staining. CONCLUSION: Diffusion-weighted MR image can be used to detect early parenchymal change when the appropriate b-factor range was applied.

Paraneoplastic neutrophilia caused by a squamous cell carcinoma of the uterine cervix has been seen rarely. We report a case of relapsed squamous cell carcinoma of the uterine cervix with severe neutrophilia, rapid tumor growth and aggressive clinical course, possibly due to autocrine stimulation of cell growth by G-CSF and IL-6 without other possible causes of neutrophilia.

PURPOSE: To evaluate the effect and improvement of potassium aminobenzoate (500 mg Peyron capsule) in oral therapy for Peyronie's disease. MATERIALS AND METHODS: From February 2011 to September 2011, 31 patients with Peyronie's disease received potassium aminobezoate (500 mg Peyron capsules) and were divided into two groups. Group 1 (N=10) received potassium aminobezoate (500 mg Peyron capsule) 3 g four times daily without previous treatment of Peyronie's disease, while group 2 (N=21) received the same drug with previous treatment of Peyronie's disease (10 mg Tamoxifen +300 mg L-carnitine two times daily). Outcomes were assessed by subjective symptom change, pain relief, resolutions of the plaque, and curvature. RESULTS: After 3 months, there were no significant improvements in clinical outcomes of either group and among all the patients, 23 stopped taking potassium aminobezoate (23/31, 74%). The reasons for ceasing the therapy were gastrointestinal trouble (8/23, 35%), too many doses to take (7/23, 30%), ineffectiveness (6/23, 26%), and high price (2/23, 9%). CONCLUSIONS: Athough the etiology of Peyronie's disease has not been elucidated, potassium aminobenzoate in therapy of Peyronie's disease has been used. The use of this medication has the limitations of gastrointestinal trouble, ineffectiveness, too many doses, and high price. Further evaluations of the effect and appropriate dosing of potassium aminobenzoate are needed.

PURPOSE: Ureteroscopic removal of stones (URS) has been widely used to treat ureteral stones because it is comparatively safe, has a high success rate, and enables patients to rapidly return to their daily routines. However, some patients experience pain after URS, but the incidence of acute post-URS pain remains largely unknown. This study aimed to investigate the incidence of acute postoperative pain after URS and the associated risk factors. MATERIALS AND METHODS: Data for 143 consecutive patients who underwent URS from June 2008 to December 2010 were collected. After excluding 8 patients who developed intraoperative complications, the patients were divided into two groups according to postoperative pain on the first postoperative day. Acute postoperative pain was defined as a pain score greater than 4 on a visual analogue pain scale (normal range, 0 to 10). Various factors were analyzed to identify the risk factors that could predict acute postoperative pain after URS. RESULTS: The stone-free rate without URS intraoperative complications was 95.5%. A total of 21 (14.6%) patients experienced postoperative pain on the first postoperative day. Young age, psychiatric illness, history of urinary tract infection, use of a stone basket, large stone size, and prolonged operation time were identified as risk factors for acute postoperative pain. CONCLUSIONS: The incidence of acute postoperative pain is not that low and should not be overlooked, because it is associated with postoperative complications that could result in an unscheduled hospital admission or visit. Active pain control should be contemplated after URS in young patients and in those with a history of urinary tract infection, psychiatric illness, large stone size, and prolonged operation time.

We observed 469 cases (male 217 cases, female 252 cases) with dento-facial deformity for 10 years from Jan 1994 to Dec 2003. The ratio of male to female was 1:1.2 and the mean age was 23.3 years (male 24.0 years, female 22.6 years) ranged from 11 to 43 years.1) The most dominant group was related to mandibular prognathism (80.4%). A rate of 83.8% demonstrated mandibular protrusion according to Slavicek's classification (n=160), and 85.4% were classified as skeletal Class III type according to Sugawara's classification (n=151) Surgical method were divided into 355 cases of one jaw surgery (single method), 26 cases of one jaw surgery (combined method), and 77 cases of two jaw surgery. Sagittal split osteotomy were performed on 316 cases (69.0%). The average operation time and blood loss in SSRO were 4.1 +/- 2.2 hrs. and 138.8 +/- 222.6 ml (n=152)
