  • Background: Blood stasis (BS) is commonly used for pattern identification in traumatic injuries, including traffic accidents (TAs). Various studies have identified the efficacy of Korean medicine treatments for TA patients, but studies focusing on the BS-based herbal medicine (BSHM), including Tongdo-san (TDS), are rare. Methods: This was a single-center, prospective observational study, conducted from August 24th, 2018 to December 27th, 2018, which included 40 TA patients. Participants underwent routine Korean medicine treatments including acupuncture, electronic moxibustion, cupping, physical therapy, and herbal medicine. In the herbal medicine treatment, participants took BSHM with more than 3 days including taking TDS. The primary outcome measures were the scores from a 100 mm visual analogue scale (VAS) and numerical rating scale (NRS). Secondary outcome measures included scores from EuroQol-5 dimension (EQ-5D) and EQ-VAS questionnaires, the BS and cold/heat indices, and safety assessments. Results: There were significant improvements in the VAS, NRS, EQ-5D, EQ-VAS scores, and BS index after treatment. In the sub-analysis, VAS, NRS, EQ-5D, and EQ-VAS scores were higher in groups with a higher BS index. The moderate and severe BS index groups showed more improvement than the minor BS index group, and there was a significant difference in the EQ-5D scores. There was no significant differences observed in cold/heat index groups scores. Conclusion: BS is associated with TA-related symptoms. BSHM, including TDS, may significantly reduce BS, pain, and discomfort.

  • Objective: To explore the effect of portal vein chemotherapy on liver metastasis after surgical resection of colorectal cancer. Methods: Patients fulfilling the eligibility criteria were assigned to receive either surgery plus 1-week continuous infusion of 5-FU (study group) or surgery alone (observational group). Patients in the study group received portal vein chemotherapy, whereby 5-FU (1000 mg/d) and heparin (5000 IU/d) infusion was initiated from the day of surgery and lasted for 7 consecutive days. Liver metastasis was monitored during five years follow-up postoperatively. Results: Sixty four patients were recruited and assigned to the study group (12 with colon and 20 with rectal cancer) or the control group (10 with colon and 22 with rectal cancer). Liver metastasis rate was 12.5% in study and 25.0% in observational group, the difference being significant (P<0.01). Conclusion: Portal vein chemotherapy could be an effective treatment in preventing liver metastasis after surgical resection of colorectal cancer.

  • Objectives : The aim of this study is to survey adverse events of acupuncture in the course of peripheral facial palsy treatments. Methods : The prospective observational study included patients hospitalized to receive acupuncture treatments for peripheral facial palsy. All patients were surveyed daily for adverse events associated with the acupuncture treatments applied the day before. Results : A total of 50 patients received $37.68{\pm}20.37$ acupuncture treatments in average. 36 patients reported experiencing at least one adverse event. Total 163 adverse events were reported. Common adverse events were bleeding(62), bruise(33), pain(30), tiredness(11), hematoma(7). The others were paresthesia(4), erythema(3), delay of removing needles(2), edema(2), aggravation of symptoms(2), declining of appetite(2), pruritus(1), drowsiness(1), anxiety(1), sweating(1), headache(1). Conclusions : Acupuncture has adverse events, like any therapeutic approaches. However, it is a relatively safe treatment. In future study, organized large scale prospective survey should be carried out to fully prove that acupuncture is safe.

  • Objectives: Several preclinical and observational studies have shown that anti-diabetic medications (ADMs) may modify the risk of lung cancer. We performed a systematic review and meta-analysis evaluating the effect of metformin, sulfonylureas (SUs), thiazolidinediones (TZDs), and insulin on the risk of lung cancer in patients with diabetes mellitus (DM). Materials and Methods: We conducted a systematic search of Pubmed and Web of Science, up to August 20, 2013. We also searched the Conference Proceedings Citation Index (CPCI) and China National Knowledge Infrastructure (CNKI) for abstracts from major meetings. Fixed or random effect pooled measures were selected based on heterogeneity among studies, which was evaluated using Q test and the I2 of Higgins and Thompson. Meta-regression was used to explore the sources of between-study heterogeneity. Publication bias was analyzed by Begg's funnel plot and Egger's regression test. Associations were assessed by odds ratios (ORs) with 95% confidence intervals (CIs). Results: A total of 15 studies (11 cohort, 4 case-control) were included in this meta-analysis. In observational studies no significant association between metformin (n=11 studies; adjusted OR=0.99, 95%CI: 0.87-1.12), SUs (n=5 studies; adjusted OR=0.98, 95%CI: 0.79-1.22), or TZDs (n=7 studies; adjusted OR=0.92, 95%CI: 0.75-1.13), insulin (n=6 studies; adjusted OR=1.13, 95%CI: 0.79-1.62) use and risk of developing lung cancer was noted. There was considerable inherent heterogeneity between studies not explained by study design, setting, or location. Conclusions: Meta-analysis of existing studies does not support a protective or harmful association between ADMs use and risk of lung cancer in patients with DM. There was considerable heterogeneity across studies, and future, well-designed, prospective studies would be required for better understanding of any association.

  • Larygopharyngeal reflux(LPR) is one form of the Gastroesophageal Reflux Diseases(GERD). It is known to cause various kinds of otolaryngologic symptoms such as hoarseness, globus sensation in throat, chronic throat clearing, and chronic cough, Disease entities diagnosed by otolaryngologists as posterior laryngitis, globus pharyngeus and reflux laryngitis should be suspected as LPR-related diseases. The nizatidine(AXID), as a Histamine H2-receptor antagonist, reduces gastric acid secretion and improves gastric motility function. Objectives : The effect of nizatidine using 150mg b.i.d was evaluated for symptom relief and improvement of laryngoscopic findings in patients with LPR. Materials and Methods : In 30 multicenter, observational trial performed nationalwidely in Korea. 308 patients with LPR symptom were observed to evaluate their symptoms and larygnoscopic findings after 4weeks, 8weeks, 12weeks of treatment with nizatidine. Results : The symptoms of LPR including globus sensation, chronic throat clearing and hoarseness, are reduced significantly after 4 weeks, 8weeks, and 12weeks of treatment(p<0.05). The laryngoscopic findings including diffuse erythema, edema and granulation are improved after nizatidine treatment(p<0.05). and the efficacy of nizatidine on LPR-related sympoms after 4 weeks is 88.6%, and those of after 8 weeks and 12weeks were 92.6%, and 99.1% in ITT(Intent To Treatment) group(p<0.05). And PPA(Per Protocol Analysis)group showed 93.7%, 97.3%, and 99.1% of efficacy after 4, 8, and 12 weeks of nizatidine treatment(p<0.05). Conclusion : These results indicate that in patient with LPR, nizatidine 150mg b.i.d treatment very effectively reduces LPR symptoms and improves laryngoscopic findings as well as reduces gastric acid secretion and improves gastric motility function.

  • Background: This study aims to statistically analyze and compare the curative effect and satisfaction level between typical traditional Korean medicine treatment and nonsurgical spinal decompression treatment. Methods: Of the patients who were diagnosed with the cervical or lumbar herniated intervertebral disc at the Department of Acupuncture and Moxibustion Medicine at the Daejeon Korean Medicine Hospital from April 14th to August 25th, 2019, this study retrospectively analyzed the medical records of 31 patients who underwent nonsurgical spinal decompression treatment and traditional Korean medicine (assigned to Group A) and another 31 patients who received typical traditional Korean medicine alone (assigned to Group B). The clinical data were analyzed using IBM SPSS Version 23.0. Results: No statistically significant differences appeared in terms of sociodemographic, condition, and therapeutic characteristics, except whether the patient received Western medicine treatment, before or after a treatment with traditional Korean medicine. Group A exhibited higher variations in numeric rating scale, EuroQol- 5 dimension and EuroQol visual analogue scale scores compared to Group B as determined by independent sample t test and analysis of covariance. In addition, the satisfaction score of Group A was higher than that of Group B The result of cross analysis revealed that desire for continued treatment in Group A was higher than that of Group B. Conclusion: This retrospective observational study showed that the patients with nonsurgical spinal decompression treatment reported a greater reduction in pain, improved quality of life and satisfaction than patients receiving typical traditional Korean medicine.

  • Background: Epidemiology studies have shown an inconclusive relationship between phytoestrogen intake and ovarian cancer risk and there have been no relevant meta-analyses directly regarding this topic. The purpose of the present meta-analysis was therefore to investigate any association between phytoestrogen intake and ovarian cancer in detail. Materials and Methods: We conducted a search of PubMed, EMBASE, EBSCO, the Cochrane Library, CNKI and Chinese Biomedical Database (up to April 2014) using common keywords for studies that focused on phytoestrogen and ovarian cancer risk. Study-specific risk estimates (RRs) were pooled using fixed effect or random-effect models. Results: Ten epidemiologic studies were finally included in the meta-analysis. The total results indicated higher phytoestrogen intake was associated with a reduced ovarian cancer risk (RR, 0.70; 95%CI: 0.56-0.87). The association was similar in sensitivity analysis. Meta regression analysis demonstrated sources and possibly types and regions as heterogeneous factors. Subgroup analysis of types, sources and regions showed that isoflavones (RR: 0.63; 95%CI: 0.46, 0.86), soy foods (RR: 0.51; 95%CI: 0.39, 0.68) and an Asian diet (RR: 0.48; 95%CI: 0.37, 0.63) intake could reduce the incidence of ovarian cancer. Conclusions: Our findings show possible protection by phytoestrogens against ovarian cancer. We emphasize specific phytoestrogens from soy foods, but not all could reduce the risk. The habit of plentiful phytoestrogen intake by Asians is worthy to recommendation. However, we still need additional larger well designed observational studies to fully characterize underlying associations.

  • Objectives: An ambulance can be a potential source of contagious or droplet infection of a community. We estimated the prevalence of positive carriage of tuberculosis (TB), methicillin-resistant $Staphylococcus$ $aureus$ (MRSA), and vancomycin-resistant $Enterococci$ (VRE) in patients transported by ambulance. Methods: This was a retrospective observational study. We enrolled all patients who visited a tertiary teaching hospital emergency department (ED). Blood, sputum, urine, body fluid, and rectal swab samples were taken from patients when they were suspected of TB, MRSA, or VRE in the ED. The patients were categorized into three groups: pre-hospital ambulance (PA) group; inter-facility ambulance (IA) group; and non-ambulance (NA) group. Adjusted odds ratio (OR) and 95% confidence intervals (CI) were calculated using a multivariable logistic regression model for the prevalence of each infection. Results: The total number of patients was 89206. Of these, 9378 (10.5%) and 4799 (5.4%) were in the PA and IA group, respectively. The prevalence of TB, MRSA, and VRE infection were 0.3%, 1.1%, and 0.3%, respectively. In the PA group, the prevalence of TB, MRSA, and VRE were 0.3%, 1.8%, and 0.4%. In the IA group, the prevalence of TB, MRSA, and VRE were 0.7%, 4.6%, and 1.5%, respectively. The adjusted ORs (95% CI) of the PA and IA compared to the NA group were 1.02 (0.69 to 1.53) and 1.83 (1.24 to 2.71) for TB, 2.24 (1.87 to 2.69) and 5.47 (4.63 to 6.46) for MRSA, 2.59 (1.78 to 3.77) and 8.90 (6.52 to 12.14) for VRE, respectively. Conclusions: A high prevalence of positive carriage of TB, MRSA, and VRE in patients transported by metropolitan ambulances was found.

  • Objectives : To investigate the incidence of drug-induced liver injury (DILI) by combined-prescription of Korean herbal medicine (KHM; prescribed herbal medicine by doctors of traditional Korean medicine) and Western medicine on liver function. Methods : Sixty-nine in-patients who took KHM and Western medicine for various conditions were enrolled for prospective observational study. All subjects were given liver and renal function tests at the start of hospitalization to establish a baseline. After taking KHM and Western medicine, tests were done at approximately 4-week intervals afterwards. Results : Fifty-three subjects showed normal liver function test (LFT) at baseline, 50 subjects (72.5%) remained within the normal range at the second test, while 3 subjects (4.3%) tests revealed slight increase of LFT. However not a single patient had a high enough raised LFT to indicate liver injury. Sixteen of 69 subjects had abnormal baseline, 11 subjects recovered to normal levels and 5 subjects remained at abnormal level. Among all subjects, there was no statistically significant increase in LFT level between the first and second tests. Conclusions : This study shows that the combined-prescription of KHM and Western medicine did not cause any DILI. In some cases, combined treatment increased LFT levels but those increases were not high enough to have statistical significance. Additional large scale and systematical studies are required for more conclusive proof and results.

  • Objectives: The aim of this study was to identify the causal relationship between use of levocetrizine or cetrizine, and liver injury, by comparing frequency and pattern of hepatotoxicity in levocetrizine or cetrizine prescribed patients. Methods: This is a retrospective observational study, using data retrieved from electronic medical record system. Among 1164 patients prescribed levocetrizine or cetrizine during study period (Jul, 2009 - Jun, 2010) at Seoul National University Hospital, 543 patients with more than 4- time liver function test (LFT) results were included in final analysis. Liver injury was defined as greater than 3 times elevated level of alanine aminotransferase or 2 times elevated level of alkaline phosphatase or total bilirubin, compared to upper limit of normal, in patient with normal liver function at baseline. The frequency and pattern of liver injury were assessed. Results: Incidence of liver injury in patients prescribed with levotcetrizine or cetrizine were 1.48% and 2.94%, respectively. With few exceptions, most injuries were shown to be hepatocellular type. Rapid recovery was observed after drug cessation and long term use tends to be associated with incidence of liver injury. In patient with digestive system disorder, rate of liver injury was significantly higher (p=0.011). Conclusion: The result of this study implies potential need of liver toxicity monitoring, especially in patients taking long term levecetrizine or cetrizine or in patient with digestive system disorder. However, prospective large scale observational study is needed to confirm liver injury associated with the use of levocetirizine or cetirizine.
