Rhabdomyosarcoma is the most frequent cancer involving the trigone of the bladder, the proximal urethra, vagina and paratesticular tissue in children, and 15 percent of rhabdomyosarcoma in children arise in the urogenital tract. Rhabdomyosarcoma is highly malignant neoplasm with a tendency toward early infiltration of adjacent structures and metastases to regional lymphnodes and distant organs. We report tow cases of paratesticular rhabdomyosarcoma with brief review of literatures.

Testicular teratomas are germ cell neoplasms that consist of tissue derived from ectoderm, mesoderm and endoderm in various stages of maturation. The teratomas are subclassified into mature teratoma, immature teratoma, and malignant teratoma. depending on the appearance and maturity of the various components. Prognosis is directly related to maturity of the tissue. Recently we experienced two cases of testicular teratoma, so we report these two cases of testicular teratoma with review of literature.

PURPOSE: Testicular microlithiasis (TM) is an uncommon pathologic condition that is commonly diagnosed by scrotal ultrasonography. Indirect evidence suggests that this syndrome may be associated with an increased risk of testicular malignancy and infertility. MATERIALS AND METHODS: A total of 1,439 patients undergoing scrotal ultrasound during a 6-year, 5-month period (January 2003 to May 2009) were retrospectively reviewed. Any possible association of TM with pathologic findings was assessed. Among patients with TM, further grading of TM with testicular cancer and semen analysis of the infertile group with TM were also performed. RESULTS: TM was diagnosed in 87 patients (6.0%) out of a total of 1,439. Of all established pathologic entities, only testicular malignancy and infertility were meaningfully associated with TM. There was no significant difference in the prevalence of testicular cancer between each grade. Seminal profiles (sperm count, motility, morphology, and white blood cell count) were not found to be statistically different between infertile men with and without TM. CONCLUSIONS: The prevalence of TM in symptomatic men was found to be 6.0% with significant co-occurrence of TM, testicular cancer, and infertility. Further grading of TM does not seem to be essential with regard to the detection of patients with testicular cancer and TM. TM showed no significant effect on the seminal profiles of infertile men.

Spontaneous tumor rupture is a serious but rare complication of hepatocellular carcinoma (HCC) and has a low survival rate. Here, we report a case of massive HCC that ruptured and was treated successfully with transarterial chemoembolization (TACE). A 55-year-old man with abdominal pain was diagnosed with a 12-cm-wide ruptured HCC at segment 8. The overall liver function was scored as Child–Pugh A, but the single nodule tumor had ruptured; therefore, TACE treatment was initiated. After the first TACE treatment, residual tumors were found; thus, secondary TACE was performed 5 months later. No new lesions or extrahepatic metastases were found 16 months after the first TACE treatment, so hepatic resection was performed for curative treatment. The postoperative pathology results did not reveal any cancer cells; hence, TACE alone resulted in a cure. We report this case because the cure has been maintained for more than 3 years after resection.

Purpose: The purpose of this study was to evaluate the surgical outcome of split-thickness skin graft (STSG) for chronic diabetic wounds of the foot and ankle. Materials and Methods: The medical records of 20 patients who underwent surgery for chronic diabetic wounds of the foot and ankle between October 2013 and May 2018 were reviewed. Surgical management consisted of consecutive debridement, followed by negativepressure wound therapy and STSG. We used an acellular dermal matrix between the wound and the overlying STSG in some patients with wide or uneven wounds. Patient satisfaction, comorbidities, wound size and location, length of hospital stay, wound healing time, and complications were investigated. Results: Of 20 patients, 17 (85.0%) were satisfied with the surgical outcome. Eight patients had diabetic wounds associated with peripheral vascular disease (PVD), 7 patients had diabetic wounds without PVD, and 5 patients had acute infection superimposed with necrotizing abscesses. The mean size of the wound was 49.6 cm 2 . The mean length of hospital stay was 33.3 days. The mean time to wound healing was 7.9 weeks. The mean follow-up period was 25.9 months. Complications included delayed wound healing (4 cases) and recurrence of the diabetic wounds (2 cases), which were resolved by meticulous wound dressing. Conclusion STSG remains a good treatment strategy for chronic diabetic wounds of the foot and ankle.

The purpose of this study was to evaluate the usefulness of reducing of craniofacial radiation dose using automatic exposure control (AEC) technique in the 64 multi-detector computed tomography (MDCT). We used SOMATOM Definition 64 multi-detector CT, and head of whole body phantom (KUPBU-50, Kyoto Kagaku CO. Ltd). The protocol were helical scan method with 120 kVp, 1 sec of rotation time, 5 mm of slice thickness and increment, 250 mm of FOV, 512x512 of matrix size, 64x0.625 mm of collimation, and 1 of pitch. The evaluation of dose reducing effect was compared the fixed tube current of 350 with AEC technique. The image quality was measured the noise using standard deviation of CT number. The range of craniofacial bone was to mentum end from calvaria apex, which devided three regions: calvaria~superciliary ridge (1 segment), superciliary ridge~acanthion (2 segment), and acanthion~mentum (3 segment). In the fixed tube current technique, CTDIvol was 57.7 mGy, DLP was 640.2 mGy.cm in the all regions. The AEC technique was showed that 1 segment were 30.7 mGy of CTDIvol, 340.7 mGy.cm of DLP, 2 segment were 46.5 mGy of CTDIvol, 515.0 mGy.cm of DLP, and 3 segment were 30.3 mGy of CTDIvol, 337.0 mGy.cm of DLP. The standard deviation of CT number was 2.622 with the fixed tube current technique and 3.023 with the AEC technique in the 1 segment, was 3.118 with the fixed tube current technique and 3.379 with the AEC technique in the 2 segment, was 2.670 with the fixed tube current technique and 3.186 with the AEC technique in the 3 segment. The craniofacial radiation dose using AEC Technique in the 64 MDCT was evaluated the usefulness of reducing for the eye, the parotid and thyroid with high radiation sensitivity particularly.

Hydrogen peroxide solution is commonly used for irrigating and cleaning wounds. When it is applied to tissues, catalase causes its rapid molecular degeneration with the release of oxygen bubbles. We present case report illustrating two hazards ; chemical colitis and oxygen embolus. A 29-year-old previously healthy woman presented to the bloody diarrhea and anal pain after hydrogen peroxide enema. In the colonoscopic examination, severe mucosal edema and ulceration with bleeding was noted from anus to sigmoid colon. With use of anal endosonography, multiple high level echo were noted in the internal and external anal sphincter of the upper anal canal. Microscopically, mononuclear cells were infiltrated in lamina propria and congestion. She had treatment with IV fluid, IV antibiotics and NPO. At 3rd hospital day, anal pain was disappeared. Bloody stool was disappeared next day. At 8th hospital day, mucosal edema and ulceration were disappeared on colonoscopic examination. Recovery was full and the patient was discharged at nine days after the episode.

BACKGROUND: The catheter ablation usin radiofrequency(RF) energy in patients with atrioventricular nodal reentrant tachycardia(AVNRT) and atrioventricular reentrant tachycardia(AVRT) ahs been proved as a safe and effective nonpharmacologic therapeutic modality. The purpose of our study was to evaluate the success rate and complications of the initial experience and to determine the extent of myocardial damage of RF catheter ablation. METHODS: Electrophysiologic study was performed with the standard technique. Twenty five patinents(M:F=16:9, mean age:42 years old) underwent RF catheter ablation in St. May's Hospital from April to December in 1994. The RF generator in this study was RFG-3D model and catheters were 6F or 7F steerable catheters with 4mm kistal tip. In order to evaluate the extent of myocardial damage the WBC count, LDH, CK, and CK-MB fraction were checked before and after RF catheter ablation and the Tc99m myocardial scintigraphy was performed within 72 hours of the porcedure. RESULTS: Six of twenty five patients had AVNRT, in which the success rate of selective ablation of the slow pathway was 83.8%. Nineteen patients with AVRT had one accessory pathway. The ablation success rate of 14 accessory pathways in left free wall location was 85.7%, and that of 3 in left posteroseptal location was 66.6%. Two right sided accessory pathways were not ablated successfully. The level of CK-MB fraction after ablation was within normal limit. Only one case revealed grade 2 of hot spot in Tc99m myocardial scintigraphy. CONCLUSION: The RF catheter ablation in patients with AVNRT and AVRT is a safe and effective nonpharmacologic therapeutic modality. But right sided accessory pathways are more difficult to ablate than left sided accessory pathways, requiring more experiences and better technique. The extent of myocardial damage after RF catheter ablation reveals relatively minimal by cardiac enzyme study and Tc99mmyocardial scintigraphy.
