Objective: To investigate the effects of a herb complex extract (HCE) prepared from Cornus officinalis Sieb. Et Zucc., Eriobotrya japonica Lindley, and olive leaves on immune response of mouse spleen NK cells in vitro and in vivo analysis. Methods: The activity of natural killer (NK) cells was measured in splenocytes and YAC-1 cells. Mice were immunosuppressed using cyclophosphamide (5 mg/kg body weight). Three different doses of HCE (200, 400, and 800 mg/kg body weight) and red ginseng extract (800 mg/kg body weight) which was used as standard immunomodulatory herb were administered orally for 4 weeks. The body weight, dietary, water intake, organs (liver, thymus, and spleen) weight, completed blood count, and cytokines (tumor necrosis factor alpha, interferon gamma, and interleukin-2) production was measured. Results: At the maximum concentration of HCE, the activity of NK cells was increased by 48.5%. HCE increased liver, spleen, and thymus weights without altering numbers of white blood cells, lymphocytes, and neutrophils in a cyclophosphamide-induced immunosuppression rat model. However, HCE recovered the inhibited cytokine expression; HCE (800 mg/kg) increased cytokines levels. The results indicate the immune enhancement potential of this HCE. Conclusion: The HCE enhances immunity by increasing NK cell activity, regulating cytokine levels, and maintaining spleen weight. Therefore, it may be used as a potential immunity enhancer.

BACKGROUND: This study aimed to assess the treatment outcomes of ifosphamide, mesna, etoposide, and prednisolone (IMEP) combination regimen as a front-line chemotherapy in patients with peripheral T-cell lymphomas (PTCLs). METHODS: Clinical data of 38 newly diagnosed PTCLs patients who underwent IMEP at Busan Paik Hospital from January 2002 to December 2013 were retrospectively analyzed. RESULTS: The overall response rate was 68.5%, with 21 (55.3%) complete response/complete response unconfirmed and 6 (15.8%) partial response (PR). The median follow-up duration was 25.5 months (range, 0.2-87.3). The median overall survival was not reached and 2-year survival rate was 67%. The median progression free survival was 23 months. The most frequently reported adverse effects higher than grade 3 were hematologic toxicities including neutropenia (68.4%), thrombocytopenia (42.1%). There was no treatment-related mortality. CONCLUSION: IMEP regimen is effective and safe as a front-line chemotherapy in patients with PTCLs.

BACKGROUND/AIMS: Colorectal cancer (CRC) develops from colonic adenomas. Type 2 diabetes mellitus (DM) is associated with a higher risk of CRC and metformin decreases CRC risk. However, it is not certain if metformin affects the development of colorectal polyps and adenomas. This study aimed to elucidate if metforminaffects the incidence of colonic polyps and adenomas in patients with type 2 DM. METHODS: Of 12,186 patients with type 2 DM, 3,775 underwent colonoscopy between May 2001 and March 2013. This study enrolled 3,105 of these patients, and divided them in two groups: 912 patients with metformin use and 2,193 patients without metformin use. Patient clinical characteristics, polyp and adenoma detection rate in the two groups were analyzed retrospectively. RESULTS: The Colorectal polyp detection rate was lower in the metformin group than in the non-meformin group (39.4% vs. 62.4%, P<0.01). Colorectal adenoma detection rate was significantly lower in the metformin group than in the non-metformin group (15.2% vs. 20.5%, P<0.01). Fewer advanced adenomas were detected in the metformin group than in the non-metformin group (12.2% vs. 22%, P<0.01). Multivariate analysis identified age, sex, Body mass index and metformin use as factors associated with polyp incidence, whereas only metforminwas independently associated with decreased adenoma incidence (Odd ratio=0.738, 95% CI=0.554-0.983, P=0.03). CONCLUSIONS: In patients with type 2 DM, metformin reduced the incidence of adenomas that may transform into CRC. Therefore, metformin may be useful for the prevention of CRC in patients with type 2 DM.

PURPOSE: To evaluate the impact of nocturia on health-related quality of life and sleep in men. METHODS: From January 2008 to December 2008, 284 patients with lower urinary tract symptoms were selected for this study. The participants completed a series of questionnaires on health-related quality of life (the overactive bladder questionnaire, or OAB-q), the Medical Outcomes Study (MOS) sleep scale, and the frequency volume chart. RESULTS: The patient population had a mean age of 60.0+/-13.4 years (range, 40 to 79 years). The mean duration of symptoms was 28.8+/-34.6 months. The mean number of voiding episodes per night was measured as follows: 88 patients (31.0%) reported no nocturia, 60 patients (21.1%) reported 2>voids/night > or =1, 56 patients (19.7%) reported 3>voids/night > or =2, and 80 patients (28.2%) reported > or =3 voids/night. The mean number of nocturia episodes increased with age (P=0.001), and the number of nocturia episodes was significantly associated with the OAB-q symptom score (P=0.001) and symptom bother (P=0.001). Among the categories of the MOS sleep scale, sleep index I (P=0.020), sleep disturbance (P=0.010), adequacy of sleep (P=0.005), and somnolence (P=0.041) were significantly associated with an increased number of nocturia episodes. CONCLUSIONS: The number of nocturia episodes increased with age in men. Nocturia appeared to be associated with further negative effects on sleep quality, health-related quality of life, and symptom bother.

BACKGROUND/AIMS: Colonoscopy training programs and the minimal experience with colonoscopy required to be considered technically competent are not well established. The aim of this study was to determine the colonoscopy learning curves and factors associated with this difficult procedure at a single center. METHODS: A total of 3,243 colonoscopies were performed by 12 first-year gastroenterology fellows, and various clinical factors were assessed prospectively for 22 months. Acquisition of competence (success rate) was evaluated based on two objective criteria: (i) the adjusted completion rate (>90%) and (ii) cecal intubation time (<20 minutes). RESULTS: The overall success rate in reaching the cecum in less than 20 minutes was 72.8%. The cecal intubation time was 9.34+/-4.13 minutes (mean+/-SD). Trainees' skill at performing cecal intubation in <20 minutes reached the requisite standard of competence after 200 procedures. Cecal intubation time decreased significantly from 11.3 to 9.4 minutes after 100 procedures and improved continuously thereafter. Female patients and advanced patient age (over 60 years) were associated with prolonged cecal intubation time (>20 minutes). Surgery of the uterus and ovaries was significantly correlated with delayed cecal intubation time, but not after sufficient colonoscopy experience. CONCLUSIONS: The minimum number of procedures to reach technical competence was 200. The cecal intubation time was longer in female and older patients.

Hematopoietic stem cell transplantation (HSCT) recipients have a risk of post-transplant lymphoproliferative disorder (PTLD), which normally develops in Epstein-Barr virus (EBV) transformed donor B lymphocytes. The incidence of Hodgkin's lymphoma (HL) ranges from 1.8% to 3.4% of PTLD after HSCT. There are no case reports of early onset HL-like PTLD that developed less than one year after HSCT. We encountered a case of early onset PTLD after an unrelated HSCT following reduced-intensity conditioning with cyclophosphamide/fludarabine/thymoglobulin. A 24 year old patient with severe aplastic anemia developed multiple lymphadenopathies at day 95 after HSCT. The excisional biopsy revealed HL-like PTLD, which tested positive to immunohistochemical staining for the EBV. The Ann Arbor stage was IIA. Immunosuppressive agents were discontinued for 2 weeks in order to induce a graft-versus-lymphoma effect without a response. A total 4 cycles of chemotherapy with doxorubicin (adriamycin)/bleomycin/ vinblastine/dacarbazine (ABVD) and radiotherapy (total dosage 3,400 cGy) were then carried out. The response to salvage treatment was complete remission. The patient showed no evidence of the disease at the follow-up performed 32 months after HSCT.

PURPOSE: The change of quality of life following a tension-free vaginal tape (TVT) and transobturator vaginal tape (TVT-O) procedure was investigated in patients with stress urinary incontinence. MATERIALS AND METHODS: We included 86 women with stress urinary incontinence who underwent the TVT or TVT-O procedure and followed up for at least 1 year. Preoperatively, the patients were evaluated with history taking, physical examination, urodynamics to determine abdominal leak point pressure (ALPP) and pre- and postoperative quality of life was evaluated by incontinence quality of life questionnaire (I-QoL). The success after operation was defined as the absence of any subjective complaint of leakage. RESULTS: The rate of cure of TVT and TVT-O procedure were 84%, 92% and the rate of improvement of them were 16%, 8%, respectively. Preoperative patient characteristics including uroflowmetric parameters and ALPP were comparable in the two groups. The I-QoL parameters one year after surgery were statistically significant increase in I-QoL scores in each groups. There were no serious or long-term complications related to both procedures. CONCLUSIONS: These data suggest that the TVT and TVT-O procedure are effective for treating female stress incontinence and also in the aspect of improving quality.

An anomalous origin of the coronary artery with subsequent coursing between the great vessels is a rare congenital heart defect that may cause myocardial ischemia and sudden death. Several surgical techniques have been described to address this defect. An extended unroofing procedure to create an alternative ostium for the right coronary artery was successfully carried out in a patient having an anomalous origin of the right coronary artery. The newly constructed orifice was widely patent 3 months later, without any episodes of myocardial ischemia or aortic regurgitation.
