Purpose: This study evaluated the impact of auricular acupressure on depression among nurses. Methods: This study used a randomized control group pretest-posttest design. Shift-work nurses with the Patient Health Questionnaire-9 (PHQ-9) score over 5 points were randomized to the experimental group(n=20) or the control group(n=20). For the experimental group, auricular acupressure was conducted at the corresponding points of depression (TGI, AH1) weekly for seven days as well as for two weeks. The PHQ-9 was completed before intervention, as well as two weeks after intervention. Results: The mean difference in the PHQ-9 score before and after auricular acupressure in the experimental group (-4.11±2.27), was more significant than in the control group (-1.72±3.82) (t=2.28, p=.03). Conclusion Result showed that nurses who received auricular acupressure had a decrease in depression, compared to those who did not receive auricular acupressure. Further research is required, to apply the other auricular acupressure points, to evaluate the impact on depressive symptoms.

PURPOSE: We have done this retrospective study to know the relative incidences and clinical manifestations of organic acidopathies in Korea. METHODS: The results of quantitative organic acid analysis of 1,125 samples of 712 patients, referred from Jul. 1997 to Jun. 2000, were analyzed retrospectively according to four age groups (-2 mon, 3 mon-2 year, 3 years-12 years, over 12 years) and major clinical manifestations. Quantification of 83 organic acids was done with gas chromatography and mass spectrometry(GC/MS). RESULTS: We diagnosed 214 patients with 27 diseases of organic acid metabolism during this study period. Diseases found more than 10 cases are cytosolic 3-ketothiolase deficiency, mitochondrial repsiratory chain disorders, PDHC deficiency, glutaric aciduria type II and propionic aciduria. Other diseases were diagnosed in less than 10 cases, mostly one or two cases during this study period. Most of the patients had some symptoms of neurological dysfunction such as seizure activity(195 patients), developmental delay(122), mental retardation(99), hypotonia(84), movement disorders(81) and vomiting(68). CONCLUSION: Though the incidence of individual organic acidemia is low, the overall incidence of organic acidemia as a whole seems to be relatively high in Korea. Most of the patients showed some signs of neurological dysfunction.

PURPOSE: For the accurate diagnosis of organic acidopathies, quantification of urinary organic acid should be done and we should know the normal ranges of each organic acid excreted in the urine. The amount of organic acids excreted in the urine shows wide variability according to ethnic group, diet and age. We have quantified 82 organic acids to make a Korean reference value. METHODS: Organic acid concentrations were quantified with gas chromatography and the individual acids identified with mass spectrometry in urine specimens from members of the healthy Korean population of ages of one day to more than 12 years, subdivided into four age groups : neonatal period(-2 mon), infantile period(-2 year), childhood period(-12 year) and adolescent and adulthood(over 12 years). For isolation of organic acids from urine, we used solvent extraction method with ethylacetate. Derivatization was done with MSTFA(N-methyl-N-trimethylsilylfluoroacetamide). The library and four points quantification curve for the quantification of each organic acid that we used have been developed by Dr. Giudici of Kayser Permanante Metabolic Laboratory, CA., USA. RESULTS: Quantitative ranges and frequency distribution patterns of urinary organic acid excretion are reported, as a basis on which to compare results obtained for patients whose clinical condition suggests that their excretion values may be abnormal. CONCLUSION: The quantitative values we observed, enable the relative significance of different urinary metabolites to be assessed.

beta thalassemias are usually transmitted as autosomal recessive traits. However, some dominant forms of beta thalassemia have been identified in individuals who have inherited a single copy of an abnormal beta globin gene. Thalassemia intermedia with mild anemia, jaundice, and splenomegaly has been observed in these patients. Electrophoresis has shown elevated Hemoglobin(Hb) A2 and Hb F levels. In particular, there are inclusion bodies in the erythroid precursors and peripheral red blood cells after splenectomy. The molecular basis of these dominant beta thalassemias is heterogeneous. The authors studied the first Korean case of dominantly inherited beta thalassemia due to Hb Dieppe. Hb Dieppe is a missense mutation of beta codon 127(CAG->CGG)Gln->Arg. The patient in this case was characterized by moderate anemia, hypochromia, microcytosis, elevated Hb A2 levels, elevated Hb F levels and splenomegaly. The father of the patient also has the same disease. We report this case and review related literature.

PURPOSE: To validate the use of harmonic ultrasonography (US) in the detection of gallbladder microlithiasis. METHODS: From November 30, 2012, to January 18, 2014, fundamental US (FUS) and harmonic US with a high background noise (HUS-N) were performed for evaluation of gallbladder during the routine abdomen US. During the US, a dot-like stone (or stones) with Brownian motion was regarded as a positive finding of microlithiasis. Fifty-five patients with microlithiasis in the gallbladder detected on US were enrolled as the subjects of a retrospective review. With respect to the obtained images, two abdominal radiologists independently scored the conspicuity of gallbladder microlithiasis on FUS and HUS-N by using a 4-grade scale. The statistical analysis employed a kappa test and a Wilcoxon rank-sum test. RESULTS: For FUS, the conspicuity grades of gallbladder microlithiasis were G1 in 25 and 37, G2 in 21 and 9, G3 in 6 and 6, G4 in 3 and 3 patients, while HUS-N showed G1 in 0 and 0, G2 in 3 and 2, G3 in 12 and 15, and G4 in 40 and 38 patients, respectively, by each of the two radiologists. The kappa value was 0.633 for FUS between the two radiologists and 0.708 for HUS-N. HUS-N showed better conspicuity of gallbladder microlithiasis than FUS with significant P-values of less than 0.001 and 0.001 for the two radiologists, respectively. CONCLUSION: Compared with FUS, HUS-N enables better detection of microlithiasis in the gallbladder.

This study aimed to determine whether taurine supplementation improves metabolic disturbances and diabetic complications in an animal model for type 2 diabetes. We investigated whether taurine has therapeutic effects on glucose metabolism, lipid metabolism, and diabetic complications in Otsuka Long-Evans Tokushima fatty (OLETF) rats with long-term duration of diabetes. Fourteen 50-week-old OLETF rats with chronic diabetes were fed a diet supplemented with taurine (2%) or a non-supplemented control diet for 12 weeks. Taurine reduced blood glucose levels over 12 weeks, and improved OGTT outcomes at 6 weeks after taurine supplementation, in OLETF rats. Taurine significantly reduced insulin resistance but did not improve beta-cell function or islet mass. After 12 weeks, taurine significantly decreased serum levels of lipids such as triglyceride, cholesterol, high density lipoprotein cholesterol, and low density lipoprotein cholesterol. Taurine significantly reduced serum leptin, but not adiponectin levels. However, taurine had no therapeutic effect on damaged tissues. Taurine ameliorated hyperglycemia and dyslipidemia, at least in part, by improving insulin sensitivity and leptin modulation in OLETF rats with long-term diabetes. Additional study is needed to investigate whether taurine has the same beneficial effects in human diabetic patients.

BACKGROUND: E-cadherin, cortactin, and matrix metalloproteinase (MMP)-9 have roles in tumor development or progression, but their expression has not been fully investigated in pseudoepitheliomatous hyperplasia (PEH) and squamous cell carcinoma (SCC) of the head and neck. METHODS: We evaluated the immunohistochemical expression of E-cadherin, cortactin, and MMP-9 in 29 cases of PEH and 97 cases of SCC. Additionally, we evaluated their relationship with clinicopathologic factors and prognostic implications in SCC. RESULTS: Thirty-five cases of SCC showed reduced expression of E-cadherin, whereas none of the PEH did. A total of 20 cases and 11 cases of SCC were immunoreactive for cortactin and MMP-9, respectively, whereas none of the PEH did. In SCC, reduced expression of E-cadherin was correlated with cortactin expression and invasion depth. Cortactin expression was correlated with differentiation, T classification, and recurrence and/or metastasis. MMP-9 expression was correlated with invasion depth. Cortactin expression was correlated with poor overall survival and relapse-free survival and it was an independent prognostic factor. CONCLUSIONS: The reduced expression of E-cadherin and the expression of cortactin may be helpful for the differential diagnosis of PEH and SCC. Furthermore, cortactin expression in association with reduced E-cadherin expression is correlated with poor prognosis in SCC.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for diagnosis and treatment of common bile duct stones (CBDS). However it is associated with some complications. Endoscopic ultrasonography (EUS) is an efficient diagnostic tool for CBDS with better accuracy than ultrasonography (USG) or computed tomography (CT) and lower complication rate than ERCP. We evaluated the diagnostic usefulness of EUS in suspicious CBDS. METHODS: From Oct. 2001 to Mar. 2004, 84 patients with the suspicion of CBDS, without definite evidence on CT and/or USG were evaluated with EUS. The reports were reviewed retrospectively. RESULTS: Patients were 38 males, 46 females with mean age of 56 years old. CBDS were found in 25 (29.8%) patients. In the diagnosis of CBDS undetected in CT and/or USG, EUS gave 96% sensitivity, 96.6% specificity, 92.3% positive predictive value and 98.3% negative predictive value. When CBDS were found in EUS, the average sizes of CBD and CBDS were 8.8 mm (4~16.7) and 6.4 mm (3.3~9.1) respectively. Diagnostic ERCP was avoided in 54 (64.3%). EUS provided additional diagnosis such as gallbladder stones, gallbladder cancer, ampullary cancer and adenoma. No complication was associated with EUS. CONCLUSIONS: EUS is reasonably safe and accurate procedure in detecting CBDS. EUS may possibly replace diagnostic ERCP in CBDS.

PURPOSE: Influenza virus is one of the most important viruses that cause the respiratory infection seasonally. In April 2009, H1N1 was detected in America and Mexico and then there was pandemic in Korea. We investigated the difference of clinical and laboratory findings between the infections of H1N1 and Influenza B. METHODS: We have retrospectively studied the patients under age of 15 years who visited Inje University Sanggye Paik Hospital from August 2009 to April 2010. Evaluation for influenza infection was performed by rapid antigen test or multiplex reverse transcriptase polymerase chain reaction. Complete blood count with differential counts, C-reactive protein and chest X-ray were checked. RESULTS: Enrolled patients were 2,226 in H1N1-infected group and 288 in influenza B-infected group. Seasonal variation was that H1N1 in autumn and winter but influenza B in spring. The male-to-female sex ratio was same as 1.23 in each group. The mean age of H1N1-infected group was higher than influenza B-infected group (P<0.001). Fever was developed similarly in both groups (P=0.114). However, cough, sputum, rhinorrhea, vomiting, diarrhea, and headache were more prevalent in influenza B infection compared to H1N1 infection (P<0.001). Pneumonia development and admission rate were higher in influenza B infection compared to H1N1 infection (P<0.001, respectively). CONCLUSION: Although H1N1 infection spread rapidly, H1N1 caused not so severe symptoms than influenza B. Because of the possibility that influenza epidemic will develop repeatedly in the future, we need to evaluate more about different characteristics depending on the virus subtype and prepare for them.

BACKGROUND/AIMS: Antispasmodic agents have been used in the management of irritable bowel syndrome. However, systematic reviews have come to different conclusions about the efficacy in irritable bowel syndrome. Fenoverine acts as a synchronizer of smooth muscle in modulating the intracellular influx of calcium. We compared fenoverine with trimebutine for the treatment of patients with IBS. METHODS: A multicenter, randomized, double-blind, non-inferiority clinical study was conducted to compared fenoverine with trimebutine. Subjects were randomized to receive either fenoverine (100 mg three times a day) or trimebutine (150 mg three times a day) for 8 weeks. A total of 197 patients were analyzed by the intention-to-treat approach. The primary endpoint was the proportion of patients who had 30% reduction in abdominal pain or discomfort measured by bowel symptom scale (BSS) score at week 8 compared to the baseline. The secondary endpoints were changes of abdominal bloating, diarrhea, constipation, overall and total scores of BSS, and overall satisfaction. RESULTS: At week 8, fenoverine was shown to be non-inferior to trimebutine (treatment difference, 1.76%; 90% CI, -10.30-13.82; p=0.81); 69.23% (54 of 78 patients) of patients taking fenoverine and 67.47% (56 of 83 patients) of patients taking trimebutine showed 30% reduction in abdominal pain or discomfort compared to the baseline. There results of the secondary endpoints were also comparable between the fenoverine group and the trimebutine group. CONCLUSIONS: Fenoverine is non-inferior to trimebutine for treating IBS in terms of both efficacy and tolerability.
