Efficacy of a 3-Dimension HMD (Head Mounted Displayer) for Audiovisual Sexual Stimulation after Oral Phosphodiesterase Type 5 (PDE 5) Inhibitor Medication for the Diagnosis of Vasculogenic Erectile Dysfunction / 대한비뇨기과학회지

PURPOSE: The AVSS with 3-D HMD is considered to provide a more realistic image and more comfortable circumstances in which the subjects are absorbed in the stimulation. We investigated the efficacy of using 3-D combined with oral medication and a stimulation (COS) test for the evaluation of vasculogenic erectile dysfunction (ED). MATERIALS AND METHODS: 66 patients with complaints of ED, 28 patients diagnosed with vasculogenic ED and 38 patients diagnosed with psychogenic ED were included in this study. The patients were randomly divided into the 2-D group and the 3-D group. The 2-D group patients were examined with using 2-D combined an injection and a stimulation (CIS) test. The 3-D group patients were examined with 3-D CIS test. Then a week later, the patients underwent the AVSS with 3-D HMD 1 hour after oral PDE 5 inhibitor medication. The degree of erection was monitored using the Nocturnal Electrobioimpedance Volumetric Assessment (NEVA) system. RESULTS: On the 2-D CIS tests, 12 of 27 patients showed normal erection, and this resulted in a sensitivity and specificity of 72.7% and 56.3%, respectively. On the 3-D CIS tests, 20 of 39 patients showed normal erection and on the 3-D COS tests, 17 patients showed normal erection and this resulted in a sensitivity and specificity of 88.2% and 81.8%, and 94.1% and 72.7%, respectively. No significant difference were present in the results of the diagnosis between the 3-D CIS and 3-D COS tests. CONCLUSIONS: Both the 3-D CIS and 3-D COS tests offer the advantage of higher sensitivity and specificity than the conventional CIS test. The 3-D COS test may be used as a substitute for the conventional CIS test due to its simplicity and less invasive nature.

A Case of Bilateral Testicular Teratoma Found in Infant / 영남의대학술지

Testicular teratoma is characterized that has more than one germ cell layer in various stages of maturation and differentiation. The incidence of mature teratoma varies from 2 to 9% of all germinal testicular tumor. Only 3 cases of bilateral teratoma have been reported in the literature to date. The teratoma can occurs at all ages but is most common between the age of 15-35 year. It is relatively infrequently seen in childhood and infancy. In these age group, teratoma tends to be a benign. Recently, we experienced one case of bilateral testicular teratoma in 4 month-old infancy. We report a case of bilateral testicular teratoma found infancy with review of related literatures.

A Case of Infected Huge Lymphangioma in Pelvic cavity / 영남의대학술지

Lymphangioma is a benign tumor resulted from abnormal communication between large dermal lymphatic channels and central lymphatic system. The tumor is encountered more often in the neck and axilla and less often in mediastinum, omentum, retroperitoneum, and scrotum. It rarely developed at urogenital system, and there has been no previous description of lymphangioma involving the bladder wall in Korea. We report a case of 35-year-old female with infected huge lymphagioma arising from pelvic cavity and involving bladder wall.
