1.Interleukin-17 in the Inflammatory Bowel Disease.
Hanyang Medical Reviews 2013;33(1):27-32
Inflammatory bowel diseases(IBD), including Crohn's disease and ulcerative colitis, are chronic inflammatory states of the intestinal tract. While the exact mechanisms inducing chronic inflammation are still unclear, it is hypothesized that the inflammation is caused in part by an inappropriate immune response to the intestinal microflora. Although inflammatory diseases are not directly linked to patient survival, symptoms of these diseases significantly decrease quality of life. The incidence rate is higher in western people than eastern people, but the incidence rate of IBD in eastern people, including Korean, is increasing. Recently, it has been reported that IL-17 is an important factor that appears to be involved in IBD induction and progression. This report reviews many recent papers reporting the relationship between IBD and IL-17, which may provide an understanding leading to new means of prevention and treatment for IBD.

BACKGROUND/AIMS: Current international guidelines recommend colorectal cancer screening for average-risk people over 50 years of age. Accordingly, we aimed to estimate the prevalence of colorectal neoplasms in all age groups and evaluate associated risk factors. METHODS: Data of 14,932 subjects who underwent colonoscopy from July 2006 to January 2012 at Health Promotion Center, Gangnam Severance Hospital (Seoul, Korea) as part of a health check-up were reviewed retrospectively. RESULTS: The overall prevalence of colorectal neoplasms and adenoma were 34.6% and 25.3%, respectively. Colorectal adenoma was found in 3.2%, 13.0%, 21.7%, 33.8%, 44.0%, 50.5%, and 54.2% of subjects under 30 years, 30-39 years, 40-49 years, 50-59 years, 60-69 years, 70-79 years, and over 80 years of age (trend p<0.0001). Independent predictors of colorectal adenoma included male gender (OR 2.38, 95% CI 2.084-2.718), positive occult blood (2.266, 1.761-2.917), positive serology of Helicobacter pylori (1.253, 1.114-1.409) and hypertriglyceremia (1.267, 1.065-1.508). Compared to the 30-39 years of age reference group, the ORs for each age group were 0.195 (under 30 years), 1.634 (40-49 years), 2.954 (50-59 years), 5.159 (60-69 years), 5.640 (70-79 years), 11.020 (over 80 years), while the 95% CIs were 0.071-0.536 (under 30 years), 1.340-1.992 (40-49 years), 2.421-3.604 (50-59 years), 4.109-6.476 (60-69 years), 3.822-8.322 (70-79 years), and 2.809-42.234 (over 80 years). CONCLUSIONS: Colorectal adenoma prevalence increased proportionally with age. Only subjects under the age of 30 years had a definitely lower prevalence of colorectal adenoma. Male gender, positive occult blood, positive serology of H. pylori, and hypertriglyceremia were associated risk factors of colorectal adenoma.

Paragonimiasis has been continuously decreasing in Korea. However, it still occurs by ingesting raw or incompletely cooked fresh water crab or crayfish. The diagnosis of paragonimiasis is challenging because of its rarity. It may be confused with other inflammatory disease or carcinomatosis. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has lower risk of complications such as bleeding, perforation than percutaneous fine needle aspiration. EUS-FNA is more accurate and popular method to find mucosal or submucosal tumors and the lesions of several organs. Benign and malignant tumors, infectious diseases have been diagnosed by EUS-FNA, but there was no report describing the use of EUS-FNA for diagnosing paragonimiasis. Herein, we present a 47-year-old male patient with paragonimiasis diagnosed by EUS-FNA. Imaging studies revealed mass lesions in the lung and peritoneal cavity, which was eventually confirmed as paragonimiasis using EUS-FNA.

BACKGROUND: Gastric cancer is the second most common cancer in Korea. Fatigue is a common symptom among cancer survivors. The aim of this study was to identify factors associated with fatigue in gastric cancer survivors. METHODS: Data were analyzed from 199 gastric cancer survivors who visited a cancer survivor outpatient clinic from July 2013 to June 2014. Patients were surveyed using a questionnaire containing a fatigue severity scale (FSS) and questions regarding associated symptoms. Participants were divided into fatigue (FSS) and non-fatigue groups based on FSS scores (> or =4 and <4, respectively). Age, sex, weight, body mass index, cancer stage, pathology, surgery type, chemotherapy, radiotherapy, comorbid disease, family history of cancer, smoking, alcohol consumption, exercise, and laboratory results were investigated. RESULTS: The fatigue and non-fatigue groups contained 42 and 157 survivors, respectively. Their mean age was 58 years, and the mean post-operative period was 6.58 years. Arthralgia (odds ratio [OR], 12.95; 95% confidence interval [CI], 3.21-52.34), dyspnea (OR, 10.54; 95% CI, 2.94-37.80), dyspepsia (OR, 8.26; 95% CI, 2.63-25.96), changed bowel habits (OR, 4.56; 95% CI, 1.09-19.11), anemia (OR, 3.18; 95% CI, 1.26-8.05), and regular exercise (OR, 0.31; 95% CI, 0.12-0.77) were significantly associated with fatigue in gastric cancer survivors, while weight, treatment, and depressive mood were not. CONCLUSION: Arthralgia, dyspnea, dyspepsia, bowel habit change, anemia, and regular exercise are associated with fatigue in gastric cancer survivors.

Korean autoimmune pancreatitis (AIP) criteria 2007 was aimed to diagnose the wide spectrum of AIP with high sensitivity. The most crucial issue when caring for patients with suspected AIP is to differentiate AIP from pancreatic cancer. Pancreatic cancer can be distinguished from AIP by pancreatic imaging, measurement of serum IgG4 levels, endoscopic ultrasound guided fine needle aspiration and trucut biopsy, and steroid trial. Autoimmune pancreatitis is a rare systemic fibroinflammatory disease which can affect not only the pancreas, but also a variety of organs such as the bile ducts, salivary glands, retroperitoneum, and lymph nodes. Organs affected by AIP have a lymphoplasmacytic infiltrate rich in IgG4-positive cells. This inflammatory process responds dramatically to oral steroid therapy. Granulocytic epithelial lesion (GEL) positive AIP patients differ from GEL negative AIP patients in clinical features such as equal gender ratio, younger mean age, no increase in serum IgG4, no association with extrapancreatic involvement, no relapse, and frequent association with inflammatory bowel disease. Further investigation is needed to clarify the pathogenic mechanisms including more definite serological markers for theses two entities.

BACKGROUND: Oxycodone is a strong m-opioid receptor agonist and has a longer duration of analgesic effect than fentanyl. We compared the use of an intravenous (IV) bolus of oxycodone and fentanyl for postoperative analgesic efficacy after dental surgery. METHODS: Patients underwent surgical extraction under general anesthesia. We prospectively enrolled patients who had received IV oxycodone (n = 36, 0.05 mg/kg) and fentanyl (n = 36, 1 mg/kg) 10 minutes before the end of surgery. The recovery profiles (hemodynamic variables, pain score, postoperative nausea and vomiting, sedation scale, and adverse events) were recorded for 1 hour in the post-anesthetic care unit (PACU) and at 6 hours after surgery. RESULTS: Under a potency ratio of 50:1 (oxycodone:fentanyl), time to spontaneous ventilation was significantly longer in the oxycodone group (8.1 ± 2.8 min vs. 6.9 ± 1.8 min, P = 0.021). The overall pain scores were significantly lower in the oxycodone than in the fentanyl group (P < 0.001), and the oxycodone group had significantly fewer additional analgesic requirements in the PACU than the fentanyl group (8.3% vs. 27.8%, P = 0.032). The incidence of postoperative nausea and sedation were comparable in both groups. No opioid-related adverse event was identified. CONCLUSIONS: In dental surgery, 0.05 mg/kg IV oxycodone had a longer-lasting analgesic effect than that of 1 µg/kg IV fentanyl, and could reduce total opioid consumption without increasing side effects. Patients experienced satisfactory analgesia postoperatively; thus, oxycodone is an effective opioid analgesic for acute postoperative pain relief.

PURPOSE:
The aim of this study was to compare the measurements of diameter and volume of hepatic metastases from CT images with the overall survival and tumor response, in patients with unresectable liver metastases of colorectal cancer treated with a targeted agent.
MATERIALS AND METHODS:
We recruited 43 patients with unresectable liver metastases of colorectal cancer, in whom targeted therapy was used as the first-line treatment. Three-dimensional quantification of the volume of hepatic metastases was performed for each patient. An independent survival analysis using the Response Evaluation Criteria in Solid Tumors guidelines was performed and compared to the volumetric measurement. Overall survival was evaluated using the Kaplan-Meier analysis and compared to the Cox proportional hazard ratios (HRs) following univariate and multivariate analyses.
RESULTS:
In patients classified as non-progressing and progressing by the volumetric criteria, the median overall survival time was 21 months [95% confidence interval (CI): 491.25–768.75] and 11 months (95% CI: 0–949.42), respectively (p = 0.001). Using a multivariate analysis, we found that volumetric response (HR: 3.467; p = 0.002) was a significant factor affecting the overall survival in patients with liver metastases of colorectal cancer.
CONCLUSION
Volumetric assessment of liver metastases could be an alternative predictor of the overall survival of patients with liver metastases of colorectal cancer treated with a targeted agent.

BACKGROUND: In the Republic of Korea, due to the low birth rate, blood donation is expected to decrease. However, the demand for blood is increasing as the proportion of elderly has increased. Korea Centers for Disease Control and Prevention operate the Korea Blood Inventory Monitoring System (KBIMs) for detection and response to the shortage of blood. The aim of this study was to show the trend of blood supply monitored by KBIMs. METHODS: This study analyzed the red blood cell inventory ratio, average daily usage, time-lag from blood donation to transfusion and from receipt to transfusion in blood banks monitored by KBIMs from 2009 to 2012. RESULTS: A total of 25 hospitals have participated in KBIMs since 2009. The average inventory ratio of blood banks was 5.3 days. By month, the inventory ratio was highest between November and February; and by week, highest on Fridays. Daily amount of RBC utilized in hospitals peaked on Thursday by week. Time-lag from blood donation to transfusion and from receipt to transfusion in blood banks was 12.2 and 6.4 days, respectively. The inventory ratio of type-A RBC was the lowest, because of the highest level of demand. In addition, time-lags from blood donation to transfusion and from receipt to transfusion were shortest in type-A RBC. CONCLUSION: The inventory ratio in blood banks monitored by KBIMs was stable throughout the years. However, due to higher level of demand, there is a risk of shortage of type-A RBC.

Circumferential resection by performing endoscopic submucosal dissection (ESD) in the antrum can cause pyloric stenosis. Treatment with balloon dilation usually requires repeated sessions and this may cause bleeding or perforation. There are several studies regarding the treatment of benign pyloric stenosis by the temporary placement of self-expandable metallic stent (SEMS), but these studies did not include any case of pyloric stenosis caused by ESD for treating early gastric cancer (EGC). We experience a case of a man who had EGC encircling the antrum. After ESD, pyloric stenosis occurred and so a SEMS was applied. Eight weeks later, the stent was removed without complications. Stent insertion for benign pyloric stenosis has not been accepted as a standard therapeutic modality. However, continuous dilation of a stenotic lesion can be expected without major complications, except for migration. Therefore, temporary stent insertion can be considered as an alternative treatment option for benign pyloric stenosis. Further study on the long term outcome of this procedure is needed.

OBJECTIVES: This study aims to investigate the suitability of electronic health record (EHR) systems in Korea for global certification and to propose functions for future global systems by comparing and analyzing the certification criteria for Certification Commission for Health Information Technology (CCHIT) Certified Ambulatory EHR with BESTCare, which is the EHR system at Seoul National University Bundang hospital. METHODS: Domain expert groups were formed to analyze the inclusion of BESTCare functions and the types of differences for each of the CCHIT Certified 2011 Ambulatory EHR Certification Criteria. The types of differences were divided into differences in functions (F), differences in business processes (B), and differences in government policies (P). RESULTS: Generally, the criteria that showed differences in functions pertained to the connection between the diagnosis/problem list and order, the alert and warning functions for medication-diagnosis interactions, and the reminder/instruction/notification messages related to the patient's immunization status; these absent functions were enhanced clinical decision support system (CDSS) functions related to patient safety and healthcare quality. Differences in government policies were found in the pharmacy's electronic prescription functions, while differences in business processes were found in the functions constrained by the local workflow or internal policy, which require some customization. CONCLUSIONS: Functions that differed between the CCHIT certification criteria and the BESTCare system in this study should be considered when developing a global EHR system. Such a system will need to be easily customizable to adapt to various government policies and local business processes. These functions should be considered when developing a global EHR system certified by CCHIT in the future.
