The immature teratoma is extremely rare tumor consisting of mature tissues and immature embryonal tissues. The immature teratoma in children occurs more frequently at the sacrococcygeal bone, testis and ovary. Only 9.5 percent of immature teratomas occur in retroperitoneum. Often the presenting manifestation is asymptomatic with increasing abdominal distention or mass discovered during physical examination. We report a case of congenital retroperitoneal immature teratoma in 3-week-old boy who was treated by surgical excision.

PURPOSE: Renal vascular clamping during a laparoscopic partial nephrectomy is a time-consuming procedure with a risk of renal ischemia. To study the feasibility of laparoscopic partial nephrectomy without renal arterial clamping, we compared the procedure with laparoscopic partial nephrectomy with vascular clamping. MATERIALS AND METHODS: Seventeen patients underwent laparoscopic partial nephrectomy without renal arterial clamping (group 1) from February 2004 to June 2008. The operative results were reviewed retrospectively and compared with those of 16 patients who underwent laparoscopic partial nephrectomy with arterial clamping (group 2). Patient characteristics did not differ significantly between the 2 groups. However, exophytic tumors were detected in 13 patients in group 1 and 3 patients in group 2 (p=0.001). Scores on the preoperative aspects and dimensions used for an anatomical (PADUA) classification were 6.9 in group 1 and 7.7 in group 2 (p=0.037). All surgeries by the transperitoneal approach were performed by a single surgeon. RESULTS: The mean operative times were 103 and 130 minutes in groups 1 and 2, respectively (p=0.312). The mean renal arterial clamping time of group 2 was 27.6 minutes (range, 20-42 minutes). The mean estimated blood loss was 327 ml in group 1 and 315 ml in group 2 (p=0.971). The mean postoperative change in the glomerular filtration rate was 20.11 ml/min/1.73 m2 in group 1 and 18.95 ml/min/1.73 m2 in group 2 (p=0.748). The mean times to postoperative initiation of ambulation and of oral intake were 1.6 and 1.7 days (p=0.486) and 1.3 and 1.6 days (p=0.811) in groups 1 and 2, respectively. The mean length of hospital stay was 7.4 and 7.9 days in groups 1 and 2, respectively (p=0.9). The mean tumor size was 2.1 cm (range, 1-7 cm) in group 1 and 3.3 cm (range, 1.5-9 cm) in group 2. CONCLUSIONS: Laparoscopic partial nephrectomy without renal arterial clamping is feasible for a localized renal tumor. However, patients should be selected carefully, such as those with an exophytic tumor.

OBJECTIVE: To evaluate the effect of hyaluronan-rich transfer medium on pregnancy and implantation rates in fresh and frozen-thawed embryo transfers in Korean women with previous implantation failure. METHODS: This retrospective study included 283 blastocyst transfers in patients with previous embryo transfer failure at a private fertility clinic. In the study group (n=88), blastocyst transfers were performed using an hyaluronan-rich transfer medium prior to transfer, whereas blastocyst transfers without any treatment served as controls (n=195). According to the type of transfer (fresh elective or frozen-thawed), all the blastocyst transfers were divided into two study and two control groups. RESULTS: The patient's mean age, serum anti-Müllerian hormone level, causes of infertility, embryo quality, and the number of transferred embryos were comparable between the study and control groups. There were no significant differences in clinical pregnancy rate (45.5% vs. 43.1%), implantation rate (28.9% vs. 28.8%), and clinical abortion rate (10.0% vs. 8.3%) between the two groups, and these findings were not changed after subgroup analysis according to the type of transfer. CONCLUSION: The use of hyaluronan-rich transfer medium in the blastocyst transfer does not appear to have any significant effect on the implantation and pregnancy rates in patients with previous implantation failure.

PURPOSE: We evaluated the feasibility of a laparoendoscopic single-site (LESS) nephroureterectomy for an upper urinary tract tumor. MATERIALS AND METHODS: Between March 2009 and September 2009, 4 patients with upper urinary tract tumors underwent LESS nephroureterectomy. The mean age of the 2 female and 2 male patients was 69 years old, and their mean body mass index was 23.0. We used a homemade single-port device made with a surgical glove and a wound retractor, which were put into a 4 cm periumbilical incision. Operations with articulating and rigid laparoscopic instruments were performed transperitoneally. An open technique with a 4 cm additional midline incision and laparoscopic technique with an endoscopic stapler were used for the treatment of the distal ureter and bladder cuff. RESULTS: All cases were completed successfully, without conversion to conventional laparoscopy or open surgery. The mean operative time was 169.5 minutes. The mean estimated blood loss was 361.4 ml. One patient had transfusion and wound infection. The mean hospital stay was 7.8 days. The mean specimen weight and tumor size were 271.8 g and 2.9 cm. Pathologic results of all cases showed urothelial carcinoma with a negative surgical margin. Three patients were in stage T3N0M0 and 1 was in stage T2N0M0. CONCLUSIONS: Our initial experience shows that LESS nephroureterectomy with a homemade single-port device is technically feasible. However, long term follow-up for the effect on cancer control and technical development for comfortable surgery are needed.

A small number of patients have been described in whom normal male development of the external genitalia has occurred but whom the Mullerian ducts persist. The retention of Mullerian structures can be ascribed to the failure of the Sertoli cells to synthesize Mullerian duct inhibitory factor or to a defect in the response of the duct to that factor. We experienced a case of persistent Mullerian duct syndrome. which is phenotypically normal male with bilateral undescended testes, bilateral fallopian tubes and a uterus. Herein we report a case with brief review of the literatures.

OBJECTIVES: The purpose of this study was to identify variables and determine their correlation with violent behavior in trauma- and stressor-related disorder diagnostic patients. METHODS: A one-year retrospective study (2012 to 2013) was performed on 91 trauma- and stressor-related disorder diagnosed patients at Hallym University Kangnam Sacred Heart Hospital. Study data were obtained from previous medical records. The subjects were divided into two groups based on the presence of violent behavior. RESULTS: Of the 91 trauma- and stressor-related disorder diagnosed patients, 33 patients exhibited violent behavior during their clinical course. Sociodemographic factors of age and marital status and their socioeconomic-environmental status were variables significantly related with the presence of violent behavior. Clinical data from Structured Clinical Interview for DSM, Post Traumatic Growth Inventory, and Social Support Scale scores were significantly associated with violence in trauma- and stressor-related disorder patients. CONCLUSION: In the clinical course of subjects with trauma- and stressor-related disorder, appearance of violent behavior should be monitored and approached in multiple ways to address socio-demographic, clinical, and psychological problems. Monitoring of significantly related variables and treatment compliance should be considered part of an appropriate therapeutic strategy for trauma- and stressor-related disorder patients.

Aortic saddle embolus accounts for approximately 10% of all peripheral arterial emboli. The most common sources of emboli are left atrial thrombi associated with atrial fibrillation and vegetation. A 22-year-old male patient was admitted due to acute onset of orthopnea, tachypea and cough. Transthoracic and transeophageal echocardiography showed huge vegetation (3X2cm) of the posterior mitral valve leaflet which was associated with severe mitral regurgitation. On 14th hospital day, he suffered from sudden onset of weakness, pain, and coldness on both lower extremities. Follow-up echocardiography showed marked size reduction of the original mitral valve vegetation. Angiography showed aortic saddle embolus. The embolectomy of aortic saddle embolus was performed through the transfemoral approach with a Forgarty catheter. At the same time, removal of the infected mitral valve and mitral valve replacement were performed.
