Vena cava syndrome is caused by central venous obstruction and can be divided into superior vena cava syndrome and inferior vena cava (IVC) syndrome. Symptoms and signs of IVC syndrome vary from no symptoms to lower limb edema, hypotension, and typical venous stasis changes of the lower extremities, such as brownish discoloration of the skin, woody edema, and ulceration. Carbon dioxide pneumoperitoneum, lithotomy-Trendelenburg position, and abdominal obesity could increase intra-abdominal pressure. We report a patient undergoing laparoscopic surgery who showed intrathoracic herniation of peritoneal fat induced by elevated intra-abdominal pressure due to the reasons mentioned above, resulting in IVC syndrome and hypotension perioperatively. The patient was treated with a conservative approach because he was asymptomatic except for hypotension on the first postoperative day.

The authors describe the successful perioperative management of a 3-year-old boy from Dubai with glucose-6-phosphate dehydrogenase (G6PD) deficiency, who underwent robot-assisted laparoscopic pyeloplasty for complete right ureteropelvic junction obstruction. G6PD deficiency is a genetic disorder predisposing patients to hemolytic anemia from oxidative stress. Important considerations in anesthetic management include avoiding oxidative stress, which can be caused by various conditions, and monitoring for hypercapnia, which can cause acidosis and hemolysis. Laparoscopic surgery is usually associated with hypercapnia and therefore an increased risk for respiratory acidosis. During surgery in this particular case, efforts were made to avoid carbon dioxide retention and to keep the patient warm. General anesthesia was induced with thiopental sodium, rocuronium, and fentanyl, and maintained with sevoflurane. There were no signs of hemolysis in the perioperative period and he was discharged owing to his improved condition.

PURPOSE: To report on the current practices in breast magnetic resonance imaging (MRI) in Korea. MATERIALS AND METHODS: We invited the 68 members of the Korean Society of Breast Imaging who were working in hospitals with available breast MRI to participate in a survey on how they performed and interpreted breast MRI. We asked one member from each hospital to respond to the survey. A total of 22 surveys from 22 hospitals were analyzed. RESULTS: Out of 22 hospitals, 13 (59.1%) performed at least 300 breast MRI examinations per year, and 5 out of 22 (22.7%) performed > 1200 per year. Out of 31 machines, 14 (45.2%) machines were 1.5-T scanners and 17 (54.8%) were 3.0-T scanners. All hospitals did contrast-enhanced breast MRI. Full-time breast radiologists supervised the performance and interpreted breast MRI in 19 of 22 (86.4%) of hospitals. All hospitals used BI-RADS for MRI interpretation. For computer-aided detection (CAD), 13 (59.1%) hospitals sometimes or always use it and 9 (40.9%) hospitals did not use CAD. Two (9.1%) and twelve (54.5%) hospitals never and rarely interpreted breast MRI without correlating the mammography or ultrasound, respectively. The majority of respondents rarely (13/21, 61.9%) or never (5/21, 23.8%) interpreted breast MRI performed at an outside facility. Of the hospitals performing contrast-enhanced examinations, 15 of 22 (68.2%) did not perform MRI-guided interventional procedures. CONCLUSION: Breast MRI is extensively performed in Korea. The indication and practical patterns are diverse. The information from this survey would provide the basis for the development of Korean breast MRI practice guidelines.

Transurethral resection is the most efficacious and safest urologic procedure for the treatment of benign prostatic hypertrophy, prostate cancer, and bladder cancer. Complications of transurethral resection include hemorrhage, infection, transurethral resection syndrome, and bladder perforation. Early detection of bladder perforation is important because it can cause critical ventilation and hemodynamic changes. In this case, we detected bladder perforation as the cause of ventilation and hemodynamic change intraoperatively and treated it by immediate surgical repair.

We examined whether wogonin (WO) improved hippocampal neuronal activity, behavioral alterations and cognitive impairment, in rats induced by administration of trimethyltin (TMT), an organotin compound that is neurotoxic to these animals. The ability of WO to improve cognitive efficacy in the TMT-induced neurodegenerative rats was investigated using a passive avoidance test, and the Morris water maze test, and using immunohistochemistry to detect components of the acetylcholinergic system, brain-derived neurotrophic factor (BDNF), and cAMP-response element-binding protein (CREB) expression. Rats injected with TMT showed impairments in learning and memory and daily administration of WO improved memory function, and reduced aggressive behavior. Administration of WO significantly alleviated the TMT-induced loss of cholinergic immunoreactivity and restored the hippocampal expression levels of BDNF and CREB proteins and their encoding mRNAs to normal levels. These findings suggest that WO might be useful as a new therapy for treatment of various neurodegenerative diseases.

beta-asarone (BAS) is an active component of Acori graminei rhizoma, a traditional medicine used clinically in treating dementia and chronic stress in Korea. However, the cognitive effects of BAS and its mechanism of action have remained elusive. The purpose of this study was to examine whether BAS improved spatial cognitive impairment induced in rats following chronic corticosterone (CORT) administration. CORT administration (40 mg/kg, i.p., 21 days) resulted in cognitive impairment in the avoidance conditioning test (AAT) and the Morris water maze (MWM) test that was reversed by BAS (200 mg/kg, i.p). Additionally, as assessed by immunohistochemistry and RT-PCR analysis, the administration of BAS significantly alleviated memory-associated decreases in the expression levels of brain-derived neurotrophic factor (BDNF) and cAMP-response element-binding protein (CREB) proteins and mRNAs in the hippocampus. Also, BAS administration significantly restored the expression of Bax and Bcl-2 mRNAs in the hippocampus. Thus, BAS may be an effective therapeutic for learning and memory disturbances, and its neuroprotective effect was mediated, in part, by normalizing the CORT response, resulting in regulation of BDNF and CREB functions and anti-apoptosis in rats.

PURPOSE: Tuberculosis (TB) is a major infectious disease and is responsible for two million deaths annually. For the identification and quantitation of Mycobacterium tuberculosis (M. tuberculosis), a causative agent of TB, a sandwich enzyme-linked immunosorbent assay (ELISA) against the MPT64 protein of M. tuberculosis, an antigen marker of the M. tuberculosis complex, was developed. MATERIALS AND METHODS: The MPT64 protein was expressed, and anti-MPT64 monoclonal antibodies were prepared. A sandwich ELISA was established using recombinant MPT64 protein and anti-MPT64 monoclonal antibodies. The sandwich MPT64 ELISA was evaluated using reference and clinical mycobacterial strains. RESULTS: The sandwich MPT64 ELISA detected MPT64 protein from 2.1 ng/mL to 250 ng/mL (equivalent to 1.7x10(4) CFU/mL and 2.0x10(6) CFU/mL). All 389 clinical M. tuberculosis isolates tested positive in the sandwich MPT64 ELISA (sensitivity, 100%), and the assay showed no cross reactivity to any tested nontuberculous mycobacterial strain (specificity, 100%). CONCLUSION: The sandwich MPT64 ELISA is a highly sensitive and quantitative test for MPT64 protein, which can identify M. tuberculosis.

OBJECTIVE: To compare new full-field digital mammography (FFDM) with and without use of an advanced post-processing algorithm to improve image quality, lesion detection, diagnostic performance, and priority rank. MATERIALS AND METHODS: During a 22-month period, we prospectively enrolled 100 cases of specimen FFDM mammography (Brestige(R)), which was performed alone or in combination with a post-processing algorithm developed by the manufacturer: group A (SMA), specimen mammography without application of "Mammogram enhancement ver. 2.0"; group B (SMB), specimen mammography with application of "Mammogram enhancement ver. 2.0". Two sets of specimen mammographies were randomly reviewed by five experienced radiologists. Image quality, lesion detection, diagnostic performance, and priority rank with regard to image preference were evaluated. RESULTS: Three aspects of image quality (overall quality, contrast, and noise) of the SMB were significantly superior to those of SMA (p < 0.05). SMB was significantly superior to SMA for visualizing calcifications (p < 0.05). Diagnostic performance, as evaluated by cancer score, was similar between SMA and SMB. SMB was preferred to SMA by four of the five reviewers. CONCLUSION: The post-processing algorithm may improve image quality with better image preference in FFDM than without use of the software.

There is increasing evidence that dietary factors in plant-based diets are important for the prevention of chronic disease. Especially, phytonutrients in fruits and vegetables have been recognized as major contributors for the decreased level of oxidative stress. In this study, the effect of switching the dietary habit to high consumption of fruits and vegetables were evaluated on the parameters of serum antioxidant status in healthy high school students. Forty one students participated in a randomized controlled trial and were assigned to the control group (n = 18) or the intervention group (n = 23). The intervention group was provided for 8 weeks with the main food source being whole grain and vegetables. Anthropometric measurements, blood parameters and dietary intakes were measured, and compared before and after study. After 8 weeks, weight and BMI were significantly decreased in the intervention group (p = 0.000). The serum diacron reactive oxygen metabolites (d-ROMs) test resulted in a significantly decreased level only in the intervention group (p < 0.05) after 8 weeks, but serum biological antioxidant potential (BAP) was increased significantly in both groups (p < 0.001). Intake of energy, total fat, cholesterol and sodium in the intervention group were significantly decreased after 8 weeks (p < 0.05). Also, the intervention group had significantly increased vitamin and phytonutrient intakes of all-trans-beta-carotene, alpha-carotene, alpha-tocopherol, ascorbic acid, and total phenols (p < 0.05). Overall, the results of this study suggest that whole grain, fruits, and vegetables supplementation showed improvement of the adolescent health.
