Limb-Body Wall complex is a complicated with the essential features of neural-tube defects, body-wall disruption, and limb abnormalities. This complex should be distinguished from other body-wall defects including omphalocele and gastroschisis since the prognosis for limb-body wall is uniformly poor. We have experienced one case of limb-body wall complex in a 22-year-old primigravida, which is presented with a brief review of the literature.

PURPOSE: We studied the therapeutic effect and safety of transurethral prostatectomy (TURP) performed with improved instruments by a moderately experienced resectionist. PATIENTS AND METHODS: Clinical data of the 95 consecutive patients who underwent TURP by one surgeon from March 1995 to June 1997 were analyzed. During this period, a continuous-irrigation 26F TUR sheath with a 30-degree lens attached to a monitor screen was used in most patients. RESULTS: The average weight of the resected adenoma was 10.8 7.4 gm, and the resection time was 47.2 21.2 minutes. The average weight of tissue resected per minute was 0.23 0.13 gm. Six patients required transfusion, and four suffered operative complications (one bladder perforation, one bladder neck injury, and two urethral injuries that enforced prolonged catheterization). Postoperative complications developed in seven cases. The duration of postoperative urethral catheterization averaged 2.8 days. The maximal flow rate was improved from 11.3 mL/sec to 20.6 mL/sec. Subjective satisfaction was mentioned by 95.6% of patients (91/95). In comparison with data from the first authors former report, all differences in terms of resection speed, safety, and morbidity were statistically significant. The therapeutic efficacy of the operation with the new equipment seems to be superior to that of other less invasive procedures, and even in terms of complications and duration of catheterization, these results are comparable to those of other procedures. CONCLUSIONS: We think that TURP deserves to be the primary treatment modality for the patients with benign prostatic hyperplasia who need surgical therapy if the procedure is performed by a properly trained surgeon equipped with modern TUR instruments.

We report a rare case of well differentiated paratesticular liposarcoma in a 72-year -old male. His chief complaint was left painless scrotal mass for about three years. The mass was composed of hard, soft, and rubbery components and its size was 20x5x5 cm in dimension. Scrotal ultrasonography showed huge highly echogenic multilobulated mass with some calcification and CT scan excluded the presence of nodal involvement. Left radical orchiectomy was performed as treatment and the patient has survived 24 months without evidence of recurrence. Paratesticular liposarcoma is very rare and most of them are low-grade malignancies and treatment is radical orchiectomy with wide local excision.

There has been a mistake, claimed and confirmed by all the authors of Vol 50(1), 2012, p. 1-9 issue, that first author should have been Il-Han Kim instead of Kwan-Tae Noh.

Epithelioid hemangioendothelioma (EHE) is a well-differentiated and rare vascular tumor. Systemic metastases are uncommon. Herein, we present a patient with skin metastasis of pulmonary EHE (PEH) that was treated by wide excision. A 76-year-old male was evaluated due to pulmonary thromboembolism and a solitary pulmonary nodule. A biopsy was performed and pathological examination of the mass confirmed EHE. No metastasis was observed. The patient returned to care approximately two years later due to a painful nodule in the right lower leg. A skin biopsy showed metastatic EHE from the lung. We used a safety margin of 1 cm based on clinical experience, because no prior case had been reported regarding the resection margin appropriate for primary cutaneous EHE and skin metastases of PEH. At four months after surgery, the patient recovered without complications or recurrence. Skin metastasis of PEH is extremely rare, and only two cases have been reported in the literature. In this case, we report a rare case of PEH with histologically diagnosed skin metastasis that was successfully treated by curative resection. It is expected that this case report will provide a helpful contribution to the extant data regarding PEH metastases.

PURPOSE: The purpose of this study was to investigate the effects of a mouthguard on stress distribution under mandibular impact. MATERIALS AND METHODS: The FEM model of head consisted of skull, maxilla, mandible, articular disc, teeth, and mouthguard. The impact locations on mandible were gnathion, the center of inferior border, and the anterior edge of gonial angle. And the impact directions were vertical, oblique (45degrees), and horizontal. The impact load was 800 N for 0.1 sec. RESULTS: When vertical impact was applied, the similar stress and the distribution pattern was occurred without the relation of the mouthguard use (P>.05). The model with mouthguard was dispersed the stress to the teeth, the facial bone and the skull when the oblique (45degrees) impacts were happened. However, the stress was centralized on the teeth in the model without mouthguard (P<.05). The model with mouthguard was dispersed the stress to the teeth, the facial bone and the skull when the horizontal impacts was occurred. However, the stress was centralized on the teeth without mouthguard (P<.05). For all impact loads, stress concentrated on maxillary anterior teeth in model without mouthguard, on the contrary, the stress was low in the model with mouthguard and distributed broadly on maxillary anterior teeth, facial bone, and skull. CONCLUSION: The mouthguard was less effective at shock absorbing when vertical impact was added. However, it was approved that mouthguard absorbed the shock regarded to the oblique (45degrees) and horizontal impact by dispersing the shock to the broader areas and decreasing the stress.

Yonsei Dermatology celebrated its centennial in 2017, marking 100 years since Kung Sun Oh established the first Department of Dermatology and Urology in Korea in 1917. Following the footsteps of Kung Sun Oh, a pioneer of Korean dermatology, its members united and worked to provide the best medical service and achieve academic milestones in dermatology. Over the past hundred years, Yonsei Dermatology has played a pivotal role in the advancement of medical science and academia in Korea. The main activities of the department include medical care, education, and dermatologic research. Its research activities have encompassed a wide spectrum of dermatologic manifestations from skin immunology and pathology to introduction of newly developed treatment technologies. As Kung Sun Oh was the first Korean professor of dermatology at Severance Medical School and a passionate educator, we continue to serve his will by nurturing medical students and dermatology specialists to serve as global medical leaders. The Kung Sun Oh Memorial Lecture, first hosted in 1977, was the beginning of mutual international academic exchange in the field of dermatology in Korea. The memorial lecture has played a major role in advancing the academic status of Korean dermatological science by inviting distinguished dermatologists from around the world as guest lecturers. Yonsei Dermatology has played a key role in the history of modern medicine and dermatology in Korea over the last 100 years and continues to make an impact.
