Background: Reducing the compensatory mechanism by restraining unnecessary trunk movements may help enhance the effectiveness of robot-assisted therapy.

Objective: This study aimed to investigate the effects of robot-assisted therapy in combination with trunk restraint on upper extremity function and on daily activities in patients with acute stroke (≤ 30days of onset).

Methods: Thirty-six acute stroke patients were randomly assigned to an experimental (n=18) or control (n=18) group.

Effects of Dual-Task Gait Treadmill Training on Gait Ability, Dual-Task Interference, and Fall Efficacy in People With Stroke: A Randomized Controlled Trial.

Objective: This study aimed to investigate the effects of dual-task gait training using a treadmill on gait ability, dual-task interference, and fall efficacy in people with stroke.

Methods: Patients with chronic stroke (N = 34) were recruited and randomly allocated to the experimental or control group. Both groups underwent gait training on a treadmill and a cognitive task.

Comparison of ground reaction force during gait between the nonparetic side in hemiparetic patients and the dominant side in healthy subjects.

Considering the occurrence of gait impairment following stroke, walk-ing recovery is an important goal of rehabilitation. Ground reaction force (GRF) is used for gait assessment of rehabilitation progress during exercise in stroke patients. The aim of this study was to compare the GRF during gait of the nonparetic side in hemiparetic patients and the dominant side in healthy subjects.

Totally Laparoscopic Distal Gastrectomy in Post Liver Transplant Patient.

The risk of malignancy after transplantation is higher than that of general population. Laparoscopic surgery has become a standard treatment of gastric cancer. However, there are no case reports evaluating totally laparoscopic gastrectomy in patients with previous liver transplantation.

Six-month functional recovery of stroke patients: a multi-time-point study.

The aim of this study is to compare the time-course changes in neurologic impairments (trunk control, motor function, sensory, and cognition) and recovery in functional impairments (activity of daily livings and gait) simultaneously from initiating rehabilitation to 6 months after stroke. Consecutive stroke patients were recruited from the department of nervous surgery, and transferred into the department of rehabilitation medicine and continued on treatment during the acute stage. Outcome measures were examined at the initial rehabilitation baseline, 1, 2, and 4 weeks after rehabilitation treatment, and 3, 4, 5, and 6 months after stroke.

Beneficial effect of low caloric intake in the early period after orthotopic liver transplantation: a new concept using graft weight.

Background/aims: Although various factors are correlated with early graft function after orthotopic liver transplantation (OLT), caloric supplementation is not considered in postoperative period. This retrospective study investigated the correlation between caloric intake and early graft function and compared calorie/ body weight ratio (CBWR) and calorie/graft weight ratio (CGWR) as standards for nutritional provision.

Methodology: Patients were divided into the low caloric group (<18 kcal/kg/day) and eucaloric group (≥18 kcal/kg/day) according to caloric intake until 48 hours post-OLT.

Analysis of gallbladder polypoid lesion size as an indication of the risk of gallbladder cancer.

Backgrounds/aims: Recent advances in ultrasonography have contributed to the early detection of gallbladder cancer. We attempted to predict the progression of the disease by comparing the sizes of polypoid lesions, and we suggest that the size of the lesion would be a useful guideline to determine an appropriate primary surgical approach for polypoid lesions of the gallbladder.

Methods: We have retrospectively analyzed 253 patients that, during the operation period from January 2009 to December 2011, had had ultrasonographically detected gallbladder polypoid lesions, and who underwent cholecystectomy at Ulsan university hospital.

A case of rapunzel syndrome.

Rapunzel syndrome refers to a very rare condition in which swallowed hair forms a gastric trichobezoar that has a long tail extending into the small bowel. We describe a case of Rapunzel syndrome in an 8-year-old girl who presented with abdominal mass, epigastric pain and vomiting. Abdominal computed tomography scan showed a markedly dilated stomach filled with coarse heterogeneous materials.

Ladder-type SAW filters using thinned density of randomly distributed "hot" electrodes.

A new method for the design of relatively narrowband ladder-type SAW filters is proposed. It consists of the thinning procedure and consecutive randomization of positions of the remaining transductive periods inside the IDT to suppress undesirable additional passbands. A 0.

Fragile histidine triad gene alterations are not essential for hepatocellular carcinoma development in South Korea.

Aim: To establish the role of FHIT in the pathogenesis hepatocellular carcinoma (HCC).

Methods: We examined genomic alterations, as well as, mRNA and protein expression patterns from the FHIT gene, in 48 surgically resected hepatocellular carcinoma (HCC) tissues. Additionally, p53 mutations were analyzed.

Mitotic checkpoint gene MAD1 in hepatocellular carcinoma is associated with tumor recurrence after surgical resection.

Objective: Underlying mechanism of mitotic checkpoint gene mitosis arrest deficiency 1 (MAD1) in human hepatocellular carcinoma (HCC) is rarely known.

Materials And Methods: We studied genetic change of the MAD1 gene as well as protein expression in 44 HCC and their associated non-cancerous surrounding liver tissues.

Results: Genotype AG of MAD1 G-1849 A promoter was highly significant in microscopic vascular invasion than other genotypes (P = 0.

[Hemobilia from pancreatic arteriovenous malformation: successful treatment with transportal coil embolization of draining veins].

Pancreatic arteriovenous malformations (AVM) are extremely rare diseases frequently complicated by gastrointestinal hemorrhage. While surgical resection of affected lesion is preferred for the treatment of pancreatic AVM, angiographic intervention can be used as an alternative treatment, especially in surgically high-risk patients. We experienced a patient with pancreatic AVM manifested by hemobilia and biliary sepsis.

Fixed dose rate infusion of gemcitabine with oral doxifluridine and leucovorin for advanced unresectable pancreatic cancer: a phase II study.

The standard beneficial chemotherapy proven for patients with advanced pancreatic cancer is a regimen containing gemcitabine. In the pregemcitabine era, 5-fluorouracil (5-FU) was the standard agent. Oral 5-FU can be added to gemcitabine to improve the efficacy of chemotherapy and to provide better patient convenience.

Benign retroperitoneal schwannoma: surgical consideration.

Schwannoma, which arises from the neural sheath of peripheral nerves, is the most common benign tumor in the retroperitoneum in adults. Complete excision is the treatment of choice for retroperitoneal schwannoma. During surgery, it seems to be unnecessary to identify the small peripheral nerve from which it develops.

Duodenal duplicated cyst manifested by acute pancreatitis and obstructive jaundice in an elderly man.

A duodenal duplication cyst is an uncommon congenital anomaly that is usually encountered during infancy or in early childhood. Duodenal duplication cysts generally appear on the first or second portion of the duodenum and may cause duodenal obstruction, hemorrhage or pancreatitis. Here, we report a case of a duodenal duplication cyst on the second and third portion of the duodenum in an old aged man with obstructive jaundice and acute pancreatitis, which was treated successfully by a surgical excision.

A case of simultaneous xanthogranulomatous cholecystitis and carcinoma of the gallbladder.

Xanthogranulomatous cholecystitis (XGC) is a rare inflammatory disease of the gallbladder. Not only does XGC occasionally present as a mass formation with adjacent organ invasion like a malignant neoplasm, it can also infrequently be associated with gallbladder cancer. In the situation, it is difficult to make a differential diagnosis between the diseases.

Gemcitabine therapy in patients with advanced pancreatic cancer.

Background: Advanced, unresectable pancreatic cancer is an extremely aggressive disease. The 5-year survival rate for pancreatic cancer is only less than 5%. Current therapeutic options for patients with locally advanced or metastatic disease are limited.
