Purpose: To retrospective assess the potential predictors for relapse and create an effective clinical mode for surveillance after orchidectomy in clinical stage I non-seminomatous germ cell testicular tumors (CSI-NSGCTs). Materials and Methods: We analyzed data for CSI-NSGCTs patients with non-lymphatic vascular invasion, %ECa < 50% (percentage of embryonal carcinoma < 50%), and negative or declining tumor markers to their half-life following orchidectomy (defined as low-risk patients); these patients were recruited from four Chinese centers between January 1999 and October 2013. Patients were divided into active surveillance group and retroperitoneal lymph node dissection (RPLND) group according to different therapeutic methods after radical orchidectomy was performed. The disease-free survival rates (DFSR) and overall survival rates (OSR) of the two groups were compared by Kaplan-Meier analysis. Results: A total of 121 patients with CSI-NSGCT were collected from four centers, and 81 low-risk patients, including 54 with active surveillance and 27 with RPLND, were enrolled at last. The median follow-up duration was 66.2 (range 6-164) months in the RPLND group and 65.9 (range 8-179) months in the surveillance group. OSR was 100% in active surveillance and RPLND groups, and DFSR was 89.8% and 87.0%, respectively. No significant difference was observed between these two groups ($X_2=0.108$, P=0.743). No significant difference was observed between the patients with a low percentage of embryonal carcinoma (<50%) and those without embryonal carcinoma (87.0% and 91.9%, $X_2=0.154$, P=0.645). No treatment-related complications were observed in the active surveillance group whereas minor and major complications were observed in 13.0% and 26.1% of the RPLND group, respectively. Conclusions: Active surveillance resulted in similar DFSR and OSR compared with RPLND in our trial. Patients with low-risk CSI-NSGCTs could benefit from risk-adapted surveillance after these patients were subjected to radical orchidectomy.

Abdominal compartment syndrome (ACS) is a life-threatening disorder caused by rapidly increasing intra-abdominal pressure. ACS can result in multiorgan failure and carries a mortality of 60~70%. The treatment of choice in ACS is surgical decompression. There are very few reports of ACS and experience in Korea. We report 12-year-old male patient who developed an abdominal compartment syndrome due to traffic-accident-induced retroperitoneal hematomas, Which was successfully treated by performing a bedside emergency surgical decompression with open linea alba fasciotomy with intact peritoneum. When patients do not respond to medical therapy, a decompressive laparotomy is the last surgical resort. In patients with severe abdominal compartment syndrome, the use of a linea alba fasciotomy is an effective intervention to lower intra-abdominal hypertension (IAH) without the morbidity of a laparotomy. Use of a linea alba fasciotomy as a first-line intervention before committing to full abdominal decompression in patients with abdominal compartment syndrome improves physiological variables without mortality. Consideration for a linea alba fasciotomy as a bridge before full abdominal decompression needs further evaluation in patients with polytrauma abdominal compartment syndrome.

The application of polyphenols has attracted great interest in the field of functional foods and nutraceuticals due to their potential health benefits in humans. However, the effectiveness of polyphenols depends on their bioactivity and bioavailability. In the present study, the bioactive component from green tea extract (GTE) was administrated orally (50 mg/kg body weight/day) as free or in a microencapsulated form with maltodextrin in rats fed a high fructose diet. High fructose diet induced features of metabolic syndrome including hypertriglyceridemia, hyperuricemia, increased serum total cholesterol, and retroperitoneal obesity. In addition, myocardial fibrosis was increased. In rats receiving high fructose diet, the lowering of blood triglycerides, total cholesterol, non esterified fatty acid (NEFA) and uric acid, as well as the reduction in final body weight and retroperitoneal fat weight associated with the administration of GTE, led to a reversal of the features of metabolic syndrome (P < 0.05). In particular, the administration of microencapsulated GTE decreased myocardial fibrosis and increased liver catalase activity consistent with a further alleviation of serum NEFA, and hyperuricemia compared to administration of GTE. Taken together, our results suggest that microencapsulation of the bioactive components of GTE might have a protective effect on cardiovasucular system by attenuating the adverse features of myocardial fibrosis, decreasing uric acid levels and increasing hepatic catalase activity effectively by protecting their bioactivities.

An arteriovenous fistula (AVF) from the renal artery following a penetrating abdominal trauma is not common. We report the case of a 19-year-old male who presented with a knife stab wound in the right upper quadrant. Due to unstable vital signs and to the protrusion of the mesentery through the stab wound, providing definite evidence of peritoneal violation, an emergent exploratory laparotomy was carried out. There were injuries at the proximal transverse mesocolon and the second portion of the duodenum, with bile leakage. There was also a mild amount of retroperitoneal hematoma near the right kidney, without signs of expansion or pulsation. The mesocolon and the duodenum were repaired. After the operation, abdominal computerized tomography (CT) was performed, which revealed contrast from the right renal artery shunting directly into the vena cava. Transcatheter arterial embolization with a coil and vascular plug was performed, and the fistula was repaired. The patient recovered completely and was discharged without complication. For further and thorough evaluation of an abdominal trauma, especially one involving the retroperitoneum, a CT scan is recommended, when possible, either prior to surgery or after surgery when the patient is stabile. Furthermore, a lateral retroperitoneal hematoma and an AVF after a penetrating trauma may not always require exploration. Sometimes, it may be safely treated non-operatively or with embolization.

A case of retroperitoneal paraganglioma is presented with fine needle aspiration cytologic features. A 57-year-old woman complained of abdominal discomfort and left flank pain for 2 years. The abdominal CT scan revealed an ovoid mass left to the abdominal aorta. Percutaneous fine needle aspiration was performed from the mass. The smear revealed cellular sheets or groups on hemorrhagic background. The tumor cells were ovoid, round to spindle shaped with mild to moderate cellular pleomorphism. The nuclei were round to ovoid and had evenly dispersed chromatin and small nucleoli. The cytoplasm was amphophilic, finely granular and poorly defined. Cells having large or spindle nuclei were quite frequently observed, however, mitosis was not present The cytologic findings suggested paraganglioma, but the frequent spindle cell pattern and the pleomorphism made it difficult to exclude other endocrine tumors and sarcomas. The clinical, histological and ultrastructural findings as well as cytologic findings contributed to confirmatory diagnosis.

DA-11004 is a synthetic, potent NADP-dependent isocitrate dehydrogenase (IDPc) inhibitor where $IC_{50}$ for IDPc is 1.49 $\mu$M. The purpose of this study was to evaluate the effects of DA-11004 on the high fat high sucrose (HF)-induced obesity in male C57BL/6J mice. After completing a 8-week period of experimentation, the mice were sacrificed 1hr after the last DA-11004 treatment and their blood, liver, and adipose tissues (epididymal and retroperitoneal fat)were collected. There was a significant difference in the pattern of increasing body weight between the HF control and the DA-11004 group. In the DA-11004 (100 mg/kg) treated group the increase in body weight significantly declined and a content of epididymal fat and retroperitoneal fat was also significantly decreased as opposed to the HF control. DA-11004 (100 mg/kg) inhibited the IDPc activity, and thus, NADPH levels in plasma and the levels of free fatty acid (FFA) or glucose in plasma were less than the levels of the HF control group. In conclusion, DA-11004 inhibited the fatty acid synthesis in adipose tissues via IDPc inhibition, and it decreased the plasma glucose levels and FFA in HF diet-induced obesity of C57BL/6J mice.
