PURPOSE: The purpose of this study was to estimate the effects of a video low intensity exercise program provided during hemodialysis on fatigue, activity of daily living, positive psychological capital and blood pressure of patients being treated. METHODS: A non-equivalent control group pre-post test design was used. Participants were 85 hemodialysis patients assigned to either the experimental group (n=41) or the control group (n=44). The experimental group exercised for about 25 minutes 3 times a week for 8 weeks. Data analyses involved descriptive statistics, χ2 test, t-test, multiple regression and repeated measure ANOVA using SPSS/WIN 23.0. RESULTS: The exercise intervention significantly reduced post hemodialysis fatigue and significantly increased positive psychological capital. There was a significant interaction effect on time by group in blood pressure. Systolic blood pressure changes in the experimental group were stable but, changes in the control group tended to increase gradually. CONCLUSION: To reduce fatigue and increase positive psychological capital for hemodialysis patients, providing exercise during hemodialysis is recommended. Furthermore individualized exercise in terms of intensity, time, duration, etc should be developed and tested. Also, to reduce drastic blood pressure changes during hemodialysis, exercise should be provided.

PURPOSE: Salivary fluid formation is primarily driven by Ca2+-activated, apical efflux of chloride into the lumen of the salivary acinus. The anoctamin1 protein is an anion channel with properties resembling the endogenous calcium-activated chloride channels. In order to better understand the role of anoctamin proteins in salivary exocrine secretion, the expression of the ten members of the anoctamin gene family in the mouse submandibular gland was studied. METHODS: Total RNA extracted from mouse submandibular salivary glands was reverse transcribed using primer pairs to amplify the full-length coding regions of each anoctamin gene and was subcloned into plasmid vectors for DNA sequencing. Alternative splice variants were also screened by polymerase chain reaction using primer pairs that amplified six overlapping regions of the complementary DNA of each anoctamin gene, spanning multiple exons. RESULTS: Multiple anoctamin transcripts were found in the mouse submandibular salivary gland, including full-length transcripts of anoctamin1, anoctamin3, anoctamin4, anoctamin5, anoctamin6, anoctamin9, and anoctamin10. Exon-skipping splicing in the N-terminal exons of the anoctamins1, anoctamin5, and anoctamin6 genes resulted in multiple alternative splice variants. No expression of anoctamin2, anoctamin7, or anoctamin8 was found. CONCLUSIONS: The predominant anoctamin transcript expressed in the mouse submandibular gland is anoctamin1ac. The chloride channel protein produced by anoctamin1ac is likely responsible for the Ca2+-activated chloride efflux, which is the rate-limiting step in salivary exocrine secretion.

Radiofrequency ablation (RFA) is a popular technique and shows excellent local tumor control and acceptable morbidity. Although RFA is considered much safer than surgical treatment, it is not a complication-free procedure. The most common complications of percutaneous RFA areabdominal hemorrhage, abdominal infection (abscess), biliary tract damage, and ground-pad burns. Laparoscopic RFA (LRFA) is a safe, feasible treatment modality to achieve tumor destruction. LRFA has proven superior to the percutaneous approach for lesions that are difficult or impossible to treat percutaneously. Needle-track implantationafter LRFA is a rare complication in HCCs. We report a case of needle-tract implantation of HCC found in the chest wall, ribs,and diaphragm 11 months after LRFA in a 49-year-old man. Although treatment for needle-track implantation is not well established, the metastatic mass was surgically removed.

Mantle cell lymphoma (MCL) is an uncommon type of gastrointestinal lymphoma. MCL is a distinct subtype of B-cell non-Hodgkin lymphomas. The major subtype of MCL is characterized by the presence of multiple lymphomatous polyposis (MLP), in which multiple polyps are observed along the gastrointestinal tract. The malignant cells express pan B-cell marker and the T-cell marker cluster of differentiation 5. The chromosomal translocation t(11;14)(q13;q32) that causes cyclin D1 overexpression is commonly observed on the cytogenetic analysis of MCL. Survival improvement has recently been achieved for patient with MCL by the successful introduction of monoclonal antibodies and dose-intensified approaches for treatment, including autologous stem cell transplantation strategies. Some reports suggest that there is an increased incidence of second malignancies in patients with MCL or lymphoma. We report a case of MCL involving the colon; the patient was a 60-year-old man who complained of low abdominal discomfort during defecation. During the workup, a meningioma was unexpectedly discovered. On analysis, the tumor was found to be a t(11;14)-negative and non-MLP-type MCL.

BACKGROUND/AIMS: Early gastric cancer (EGC) that is undifferentiated or shows submucosal invasion has not been generally accepted as an indication for endoscopic treatment. But recently, experiences with endoscopic submucosal dissection (ESD) for undifferentiated EGC or submucosal invasive (SM) EGC have increased. The aim of this study was to evaluate clinical outcomes of ESD for EGC with undifferentiation or submucosal invasion. METHODS: Between August 2005 and August 2009, among 210 EGCs treated using ESD at our hospital, 18 lesions were diagnosed as undifferentiated gastric cancer and 41 as SM gastric cancer. A retrospective analysis was done on the medical records of these patients. RESULTS: Mean follow-up periods were 19.39+/-11.2 months. During the follow-up period, local recurrence was noted in 4 lesions. Local recurrence rates of the EGC groups (group 1, mucosal cancer with undifferentiation; group 2, SM cancer with differentiation; group 3, SM cancer with undifferentiation) were 10%, 4.5%, and 50%, respectively. Groups 1 and 2 were not significantly different in local recurrence rates compared to the mucosal cancer with differentiation group (p=0.061, p=0.125, respectively). The undifferentiated EGC group was significantly lower in curability using ESD than the differentiated EGC group (55.6% vs. 89.6%, p=0.000). The curability of the SM EGC group was lower than the mucosal EGC group (36.6% vs. 98.9%). CONCLUSIONS: Complete resection using ESD is difficult in undifferentiated and SM gastric cancers. SM cancer with undifferentiation should be treated immediately by salvage operation. For mucosal cancer with undifferentiation or SM cancer with differentiation, one should consider careful short-term follow-up.

Gastric lymphoepithelioma-like carcinoma is a rare carcinoma among gastric malignant tumor but has a good prognosis. The carcinoma has histologic feature characterized by small nest of cancer cells mixed with lymphoid stroma. We report a case with lymphoepithelioma-like carcinoma of stomach initially presenting as panperitonitis because of spontaneous tumor perforation. A 56-year-old man visited our emergency room because of epigastric pain. A preoperative abdominal CT scan showed a massive pneumoperitoneum in the upper abdomen, and the presence of gastric cancer in the lesser curvature of the stomach. An emergent laparotomy was performed followed by radical subtotal gastrectomy. Pathologic examination revealed that the tumor was a lymphoepithelioma-like gastric carcinoma.

Schwannoma is a benign neoplasm of the Schwann cells of the neural sheath. Most schwannomas occur in the head and neck, and extremities and rarely in the retroperitoneal space. The differentiation of a schwannoma from other malignant tumor or benign tumor is very difficult on a preoperative examination with ultrasonography, computed tomography or magnetic resonance imaging. Furthermore, the lesion with increased fluorodeoxyglucose uptake in PET-CT cannot exclude malignant tumor. Therefore, this lesion needs surgical excision and a histological examination with immunohistochemical staining. We report a case of schwannoma occuring in the retroperitoneal space that incidentally discovered by PET-CT for health-check up. Pathologic confirmation by laparoscopic excision was done.

BACKGROUND/AIMS: The combination therapy with peginterferon and ribavirin is a standard treatment for patients with chronic hepatitis C. However, because of the long duration of the treatment and many complications, the reduction of adherence frequently occur. This study aimed to assess influences of reduced medication adherence in the combination therapy of chronic hepatitis C patients. METHODS: We retrospectively reviewed the medical records of 82 patients with chronic hepatitis C who received a combination therapy with peginterferon and ribavirin. The patients were categorized into 3 subgroups on the basis of medication adherence. Group 1 comprised patients who received > or =80% of the recommended dosage of both peginterferon and ribavirin. Group 2 comprised those patients who received > or =80% of the recommended dosage of only 1 drug. The patients of Group 3 received <80% of the recommended dosage of both the drugs. RESULTS: Sustained virologic response (SVR)s of patients in Group 1, 2 and 3 were 85.4% (41/48), 85.7% (18/21), and 38.5% (5/13), respectively (p=0.002). SVRs of genotype 1 patients in Group 1, 2 and 3 were 84.2% (16/19), 75% (9/12), and 14.3% (1/7) , respectively (p=0.003). SVRs of genotype non-1 patients in Group 1, 2 and 3 were 86.2% (25/29), 100% (9/9), and 66.7% (4/6), respectively (p=0.196). Furthermore are SVRs significantly differed with the degree of medication adherence to either peginterferon or ribavirin (p=0.003 and 0.021, respectively). In multivariate analysis, the peginterferon dose was a significant independent factor associated with SVR. CONCLUSIONS: Medication adherence of chronic hepatitis C patients to the combination therapy with peginterferon and ribavirin is very important for achieving SVR. In particular, we think that genotype 1 patients should maintain higher adherence than genotype non-1 patients.

PURPOSE: This study was done to evaluate the accuracy and adequacy of research studies reporting statistical testing for mean differences in studies of the Korean Journal of Women Health. METHODS: Among articles published in the journal from 2007 to 2009, 75 studies using t-test, chi2-test, and ANOVA were identified. The studies were evaluated using structured analysis format for adequacy of research title, accuracy of statistical methods and presentation styles, and errors in reported statistical outcomes. RESULTS: In this study, the research titles generally reflected the purpose of research and study designs. Thus the research titles were quite comprehensive. Also, there was compatibility between the research purpose and research design. Most important though, many errors were identified in the tables of results of the statistical analysis in articles published from 2004 to 2006. CONCLUSION: Over six years, 2004 to 2009, accuracy and adequacy of research studies has improved in many aspects. In order to enhance the completeness of the published papers and to be an internationally recognized nursing journal, close attention of the researchers, reviewers and editors is necessary to avoid errors and present adequate and accurate research.

BACKGROUND/AIMS: We retrospectively analyzed comparative toxicities and efficacies of chemotherapy regimens in advanced gastric cancer (AGC) patients who achieved complete response (CR) after chemotherapy. METHODS: We reviewed the medical records of 1,203 patients, who were pathologically diagnosed as AGC in a single center between January 2001 and October 2007. On the basis of the Response Evaluation Criteria in Solid Tumors, CR was evaluated with abdominal computed tomography. Toxicities were evaluated using the National Cancer Institute's common toxicity criteria before each chemotherapy cycle. RESULTS: Among the 1,203 AGC patients enrolled in this study, 568 received chemotherapy and 635 received best supportive care. The major chemotherapy regimens were 5-fluorouracil, leucovorin and oxaliplatin (FOLFOX), docetaxel, cisplatin and 5-fluorouracil (DCF) and 5-fluorouracil, leucovorin and irinotecan (FOLFIRI). Among the 568 patients, 51 (9.0%) achieved CR (49 [8.6%] with FOLFOX [n=12], DCF [n=26], or FOLFIRI [n=11] and 2 [0.3%] with etoposide, leucovorin and 5-fluorouracil). For patients administered FOLFOX, DCF, and FOLFIRI, the median time to disease progression was 4 months (range, 1.8-59.5), 15 months (range, 2.9-31.2) and 10 months (range, 2.0-39.5), and the median survival times were 48 months (range, 5.9-74.0), 37 months (range, 14.0-86.0), and 30 months (range, 6.0-50.0), respectively. Grades 3-4 mucositis occurred mostly in patients administered DCF (n=8, 30.8%). Grades 3-4 leucopenia were observed in 1 (8.3%), 11 (42.3%), and 4 (36.4%) patients administered FOLFOX, DCF and FOLFIRI, respectively. No statistically significant differences were observed in the 3 regimens. CONCLUSIONS: All 3 regimens (FOLFOX, DCF and FOLFIRI) were active and tolerable. Their efficacies and toxicities were not significantly different.
