Objective: This study was performed to evaluate the efficacy and safety of lurasidone (160 mg/day) compared to quetiapine XR (QXR; 600 mg/day) in the treatment of acutely psychotic patients with schizophrenia. Methods: Patients were randomly assigned to 6 weeks of double-blind treatment with lurasidone 160 mg/day (n=105) or QXR 600 mg/day (n=105). Primary efficacy measure was the change from baseline to week 6 in Positive and Negative Syndrome Scale (PANSS) total score and Clinical Global Impressions severity (CGI-S) score. Adverse events, body measurements, and laboratory parameters were assessed. Results: Lurasidone demonstrated non-inferiority to QXR on the PANSS total score. Adjusted mean±standard error change at week 6 on the PANSS total score was -26.42±2.02 and -27.33±2.01 in the lurasidone and QXR group, respectively. The mean difference score was -0.91 (95% confidence interval -6.35–4.53). The lurasidone group showed a greater reduction in PANSS total and negative subscale on week 1 and a greater reduction in end-point CGI-S score compared to the QXR group. Body weight, body mass index, and waist circumference in the lurasidone group were reduced, with significantly lower mean change compared to QXR. Endpoint changes in glucose, cholesterol, triglycerides, and low-density lipoprotein levels were also significantly lower. The most common adverse drug reactions with lurasidone were akathisia and nausea. Conclusion Lurasidone 160 mg/day was found to be non-inferior to QXR 600 mg/day in the treatment of schizophrenia with comparable efficacy and tolerability. Adverse effects of lurasidone were generally tolerable, and beneficial effects on metabolic parameters can be expected.

Background: Capsular contracture is the most common serious breast surgery complication. The cause of capsular formation remains unknown, but chronic inflammation is commonly considered to cause excessive fibrosis. Curcumin has anti-inflammatory effects and thus can relieve the symptoms of inflammatory diseases, as demonstrated in animal studies. This study aimed to evaluate the effects of curcumin on the fibrous envelope covering silicone implants in a rat model. Methods: Two solid 1.8-cm oval-shaped silicone implants were placed beneath both sides of the back in 20 Sprague-Dawley rats. The control group included 10 rats that were fed a normal diet (group A), while the experimental group (group B) included the remaining 10 rats that were fed ground curcumin. En bloc excision was conducted at 8 postoperative weeks. Capsular thickness and inflammatory cell distribution were examined using a fixed tissue sample. Results: Gross findings and histologic differences between the groups were observed. The experimental group had a significantly lower mean total capsular thickness than the control group (177.4±31.4 μm vs. 145.9±32.5 μm, P=0.007). A significant decreasing tendency was found in several inflammatory cells in the experimental group (7,070±744.3/mm2 vs. 2,640±301.7/mm2, P=0.001). Conclusions Curcumin significantly reduced the inflammatory reaction, and will help to lower the risk of capsular contracture. Long-term studies are required to determine whether this hypothesis can provide a basis for a viable therapeutic strategy to reduce capsular contracture.

Purpose: We applied a low-dose fluoroscopic protocol in routine diagnostic cerebral angiography and evaluated the feasibility of the protocol. Materials and Methods: We retrospectively reviewed a total of 60 patients who underwent diagnostic cerebral angiography for various neurovascular diseases from September to November 2019. Routine protocols were used for patients in the first phase and low-dose protocols in the second phase. We compared radiation dose, fluoroscopy time, and complications between groups. Results: Age, diseases, and operators were not significantly different between the two groups. The mean fluoroscopy dose significantly decreased by 52% in the low-dose group (3.09 vs. 6.38 Gy·cm2 ); however, the total dose was not significantly different between the two groups (34.07 vs. 33.70 Gy·cm2 ). The total fluoroscopic time was slightly longer in the low-dose group, but the difference was not statistically significant (12.2. vs. 12.5 minutes). In all patients, angiography was successfully performed without complications. Conclusion The low-dose fluoroscopy protocol is feasible to apply for diagnostic cerebral angiography in that this protocol could significantly reduce the fluoroscopic dose.

PURPOSE: Laparoscopy-assisted distal gastrectomy for early gastric cancer has gained acceptance and popularity worldwide. However, laparoscopy-assisted distal gastrectomy for advanced gastric cancer is still controversial. Therefore, we propose this prospective randomized controlled multi-center trial in order to evaluate the safety and feasibility of laparoscopy assisted D2-gastrectomy for advanced stage gastric cancer. MATERIALS AND METHODS: Patients undergoing distal gastrectomy for advanced gastric cancer staged cT2/3/4 cN0/1/2/3a cM0 by endoscopy and computed tomography are eligible for enrollment after giving their informed consent. Patients will be randomized either to laparoscopy-assisted distal gastrectomy or open distal gastrectomy. Sample size calculation revealed that 102 patients are to be included per treatment arm. The primary endpoint is the non-compliance rate of D2 dissection; relevant secondary endpoints are three-year disease free survival, surgical and postoperative complications, hospital stay and unanimity rate of D2 dissection evaluated by reviewing the intraoperative video documentation. DISCUSSION: Oncologic safety is the major concern regarding laparoscopy-assisted distal gastrectomy for advanced gastric cancer. Therefore, the non-compliance rate of clearing the N2 area was chosen as the most important parameter for the technical feasibility of the laparoscopic procedure. Furthermore, surgical quality will be carefully reviewed, that is, three independent experts will review the video records and score with a check list. For a long-term result, disease free survival is considered a secondary endpoint for this trial. This study will offer promising evidence of the feasibility and safety of Laparoscopy-assisted distal gastrectomy for advanced gastric cancer.Trial Registration: NCT01088204 (international), NCCCTS-09-448 (Korea).

OBJECTIVE: To evaluate the accuracy of the swallowing kinematic analysis. METHODS: To evaluate the accuracy at various velocities of movement, we developed an instrumental model of linear and rotational movement, representing the physiologic movement of the hyoid and epiglottis, respectively. A still image of 8 objects was also used for measuring the length of the objects as a basic screening, and 18 movie files of the instrumental model, taken from videofluoroscopy with different velocities. The images and movie files were digitized and analyzed by an experienced examiner, who was blinded to the study. RESULTS: The Pearson correlation coefficients between the measured and instrumental reference values were over 0.99 (p<0.001) for all of the analyses. Bland-Altman plots showed narrow ranges of the 95% confidence interval of agreement between the measured and reference values as follows: 0.14 to 0.94 mm for distances in a still image, -0.14 to 1.09 mm/s for linear velocities, and -1.02 to 3.81 degree/s for angular velocities. CONCLUSION: Our findings demonstrate that the distance and velocity measurements obtained by swallowing kinematic analysis are highly valid in a wide range of movement velocity.

PURPOSE: Standard treatment of asymptomatic spinal cord hemangioblastoma in von Hippel-Lindau (VHL) disease has yet to be established. The purpose of this study was to propose guidelines for the treatment of asymptomatic spinal cord hemangioblastomas in VHL disease. MATERIALS AND METHODS: VHL disease patients treated for spinal cord hemangioblastomas between 1999 and 2009 were included. All spinal cord hemangioblastomas were divided into three groups: Group 1, asymptomatic tumors at initial diagnosis followed with serial imaging studies; Group 2, asymptomatic tumors at initial diagnosis that were subsequently resected; and Group 3, symptomatic tumors at initial diagnosis, all of which were resected. RESULTS: We identified 24 spinal cord hemangioblastomas in 12 patients. Groups 1, 2 and 3 comprised 13, 4 and 7 tumors, respectively. Group 1 exhibited a smaller tumor volume (257.1 mm3) and syrinx size (0.8 vertebral columns) than those of Group 2 (1304.5 mm3, 3.3 vertebral columns) and Group 3 (1787.4 mm3, 6.1 vertebral columns). No difference in tumor volume or syrinx size was observed between Groups 2 and 3. Five tumors in Group 1 were resected during follow-up because symptoms had developed or the tumor had significantly grown. Finally, among 17 asymptomatic tumors at the initial diagnosis, nine tumors were resected. Only one tumor of these nine tumors resulted in neurological deficits, while five of seven symptomatic tumors caused neurological deficits. CONCLUSION: Selective resection of asymptomatic tumors before they cause neurological deficits might bring about better outcomes.

PURPOSE: Patients with Parkinson's disease also commonly have movement disorders, osteoporosis, and other comorbidities. These patients are more likely to have complications after spinal surgery. The aim of the present study is to show the relation ship between complications of spinal surgery and Parkinson's disease. METHODS: A computerized search using diagnostic and procedural codes identified 13 patients with Parkinson's disease who underwent spinal surgery between January 1998 and December 2010. Their medical records and imaging studies were reviewed and recent updatesfor all patients were done by telephone interview. RESULTS: Retrospectively, 13 consecutive patients were reviewed. The mean age was 63.8 (range 44~87) years old and the mean durationof Parkinson's disease was 7.6 (range 1~22) years at the time of the index procedure. The mean T score of the lumbar spine on Dual-energy X-ray absorptiometry (DEXA) scan bone mineral density (BMD) was -2.5 (range -1.0~-5.1). These patients had nine lumbar lesions, two thoracic lesions, one cervical lesion, and one thoracolumbar lesion. Nine patients required no more surgical treatment for lesions which had been previously operated on (index level). However, four patients (30.8%) needed at least one more operation related to their index procedure; segmental degeneration on the adjacent levels in two, retropulsion of an intervertebral cage with screw loosening in one, and pedicle fracture in one. CONCLUSION: It has been reported that patients with Parkinson's disease have high complication rates in spinal surgery. Spine surgeons should be aware of the risk of complications and need to conduct careful follow-up after the surgery.

Tumors of the minor papilla are very rare and these tumors have generally been known as neuroendocrine tumors such as carcinoid tumor and somatostatinoma. As these are mostly submucosal tumors, their diagnosis is difficult by just performing endoscopic forceps biopsy, but diagnosis is possible by surgery or endoscopic resection. EUS and ERCP is an essential tool for the diagnosis of these tumors, and abdominal CT or MRI is also useful because there is the possibility of malignant tumors such as carcinoid tumor. For our present two cases, screening endoscopy revealed the polypoid lesion of the minor papilla. EUS disclosed that the submucosal tumor was limited to the submucosal layer and no abnormality was found from the abdominal CT and ERCP. Herein, we performed endoscopic resection for making the diagnosis and treatment. Histologically, these 2 tumors were diagnosed as ectopic pancreas and gangliocytic paraganglioma, respectively.
