Paraaortic lymph node metastasis in patients with intra-abdominal malignancies: CT vs PET
Mi-Jung Lee, Mi Jin Yun, Mi-Suk Park, Seung Hwan Cha, Myeong-Jin Kim, Jong Doo Lee, Ki Whang Kim
World Journal of Gastroenterology , 2009,
Abstract: AIM: To compare the diagnostic accuracy of computed tomography (CT) and positron emission tomography (PET) for the preoperative detection of paraaortic lymph node (PAN) metastasis in patients with intra-abdominal malignancies.METHODS: Sixty-six patients with intra-abdominal malignancies who underwent both CT and PET before lymphadenectomy were included in this study. Histopathologically, 13 patients had metastatic PAN, while 53 had non-metastatic PAN. The CT criteria for metastasis were: short diameter of > 8 mm, lobular or irregular shape, and/or combined ancillary findings, including necrosis, conglomeration, vessel encasement, and infiltration. The PET criterion was positive fluorodeoxyglucose (FDG) uptake. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of both modalities were compared with the pathologic findings, and the false positive and false negative cases with both CT and PET were analyzed.RESULTS: The sensitivity, specificity, PPV, NPV, and accuracy of CT were 61.5%, 84.9%, 50%, 90% and 80.3%, respectively. For PET, the percentages were 46.2%, 100%, 100%, 88.3%, and 89.4%. Additionally, there were 8 false positive CT cases (8/53, 15.1%) and zero false positive PET cases. Of the 13 metastatic PANs, there were 5 false negative CT scans (38.5%) and 7 (53.9%) false negative PET scans.CONCLUSION: For detecting PAN metastasis, CT is more sensitive than PET, while PET is more specific.

World Journal of Gastroenterology , 2008,
Abstract: AIM: To determine the accuracy of computed tomography (CT) and magnetic resonance (MR) for presurgical characterization of paraaortic lymph nodes in patients with pancreatico-biliary carcinoma.METHODS: Two radiologists independently evaluated CT and MR imaging of 31 patients who had undergone lymphadenectomy (9 metastatic and 22 non-metastatic paraaortic nodes). Receiver operating characteristic (ROC) curve analysis was performed using a five point scale to compare CT with MRI. To re-define the morphologic features of metastatic nodes, we evaluated CT scans from 70 patients with 23 metastatic paraaortic nodes and 47 non-metastatic ones. The short axis diameter, ratio of the short to long axis, shape, and presence of necrosis were compared between metastatic and non-metastatic nodes by independent samples t-test and Fisher’s exact test. P < 0.05 was considered statistically significant.RESULTS: The mean area under the ROC curve for CT (0.732 and 0.646, respectively) was slightly higher than that for MRI (0.725 and 0.598, respectively) without statistical significance (P = 0.940 and 0.716, respectively). The short axis diameter of the metastatic lymph nodes (mean = 9.2 mm) was significantly larger than that of non-metastatic ones (mean = 5.17 mm, P < 0.05). Metastatic nodes had more irregular margins (44.4%) and central necrosis (22.2%) than non-metastatic ones (9% and 0%, respectively), with statistical significance (P < 0.05).CONCLUSION: The accuracy of CT scan for the characterization of paraaortic nodes is not different from that of MRI. A short axis-diameter (> 5.3 mm), irregular margin, and presence of central necrosis are the suggestive morphologic features of metastatic paraaortic nodes.
18F-FDG PET Metabolic Parameters and MRI Perfusion and Diffusion Parameters in Hepatocellular Carcinoma: A Preliminary Study
Sung Jun Ahn, Mi-Suk Park, Kyung Ah Kim, Jun Yong Park, InSeong Kim, Won Joon Kang, Seung-Koo Lee, Myeong-Jin Kim
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0071571
Abstract: Objectives Glucose metabolism, perfusion, and water diffusion may have a relationship or affect each other in the same tumor. The understanding of their relationship could expand the knowledge of tumor characteristics and contribute to the field of oncologic imaging. The purpose of this study was to evaluate the relationships between metabolism, vasculature and cellularity of advanced hepatocellular carcinoma (HCC), using multimodality imaging such as 18F-FDG positron emission tomography (PET), dynamic contrast enhanced (DCE)-MRI, and diffusion weighted imaging(DWI). Materials and Methods Twenty-one patients with advanced HCC underwent 18F-FDG PET, DCE-MRI, and DWI before treatment. Maximum standard uptake values (SUVmax) from 18F-FDG-PET, variables of the volume transfer constant (Ktrans) from DCE-MRI and apparent diffusion coefficient (ADC) from DWI were obtained for the tumor and their relationships were examined by Spearman’s correlation analysis. The influence of portal vein thrombosis on SUVmax and variables of Ktrans and ADC was evaluated by Mann-Whitney test. Results SUVmax showed significant negative correlation with Ktransmax (ρ = ?0.622, p = 0.002). However, variables of ADC showed no relationship with variables of Ktrans or SUVmax (p>0.05). Whether portal vein thrombosis was present or not did not influence the SUV max and variables of ADC and Ktrans (p>0.05). Conclusion In this study, SUV was shown to be correlated with Ktrans in advanced HCCs; the higher the glucose metabolism a tumor had, the lower the perfusion it had, which might help in guiding target therapy.
Characterization of Incidental Liver Lesions: Comparison of Multidetector CT versus Gd-EOB-DTPA-Enhanced MR Imaging
Yong Eun Chung, Myeong-Jin Kim, Yeo-Eun Kim, Mi-Suk Park, Jin Young Choi, Ki Whang Kim
PLOS ONE , 2013, DOI: 10.1371/journal.pone.0066141
Abstract: As a result of recent developments in imaging modalities and wide spread routine medical checkups and screening, more incidental liver lesions are found frequently on US these days. When incidental liver lesions are found on US, physicians have to make a decision whether to just follow up or to undergo additional imaging studies for lesion characterization. In order to choose the next appropriate imaging modality, the diagnostic accuracy of each imaging study needs to be considered. Therefore, we tried to compare the accuracy of contrast-enhanced multidetector CT (MDCT) and Gd-EOB-DTPA-enhanced MRI for characterization of incidental liver masses. We included 127 incidentally found focal liver lesions (94 benign and 33 malignant) from 80 patients (M:F = 45:35) without primary extrahepatic malignancy or chronic liver disease. Two radiologists independently reviewed Gd-EOB-DTPA-enhanced MRI and MDCT. The proportion of confident interpretations for differentiation of benign and malignant lesions and for the specific diagnosis of diseases were compared. The proportion of confident interpretations for the differentiation of benign and malignant lesions was significantly higher with EOB-MRI(94.5%–97.6%) than with MDCT (74.0%–92.9%). In terms of specific diagnosis, sensitivity and accuracy were significantly higher with EOB-MRI than with MDCT for the diagnosis of focal nodular hyperplasia (FNH) and focal eosinophilic infiltration. The diagnoses of the remaining diseases were comparable between EOB-MRI and MDCT. Hence, our results suggested that Gd-EOB-MRI may provide a higher proportion of confident interpretations than MDCT, especially for the diagnosis of incidentally found FNH and focal eosinophilic infiltration.

Abstract: We have determined and analyzed the sequence of B. rapa chromosome A3. We obtained 31.9 Mb of sequences, organized into nine contigs, which incorporated 348 overlapping BAC clones. Annotation revealed 7,058 protein-coding genes, with an average gene density of 4.6 kb per gene. Analysis of chromosome collinearity with the A. thaliana genome identified conserved synteny blocks encompassing the whole of the B. rapa chromosome A3 and sections of four A. thaliana chromosomes. The frequency of tandem duplication of genes differed between the conserved genome segments in B. rapa and A. thaliana, indicating differential rates of occurrence/retention of such duplicate copies of genes. Analysis of 'ancestral karyotype' genome building blocks enabled the development of a hypothetical model for the derivation of the B. rapa chromosome A3.We report the near-complete chromosome sequence from a dicotyledonous crop species. This provides an example of the complexity of genome evolution following polyploidy. The high degree of contiguity afforded by the clone-by-clone approach provides a benchmark for the performance of whole genome shotgun approaches presently being applied in B. rapa and other species with complex genomes.The Brassicaceae family includes approximately 3,700 species in 338 genera. The species, which include the widely studied Arabidopsis thaliana, have diverse characteristics and many are of agronomic importance as vegetables, condiments, fodder, and oil crops [1]. Economically, Brassica species contribute to approximately 10% of the world's vegetable crop produce and approximately 12% of the worldwide edible oil supplies [2]. The tribe Brassiceae, which is one of 25 tribes in the Brassicaceae, consists of approximately 240 species and contains the genus Brassica. The cultivated Brassica species are B. rapa (which contains the Brassica A genome) and B. oleracea (C genome), which are grown mostly as vegetable cole crops, B. nigra (B genome) as a source of mustard co

Trials , 2010, DOI: 10.1186/1745-6215-11-107
Abstract: One hundred fifty participants with dry eye will be recruited into three independent hospitals from different areas: Korea Institute of Oriental Medicine, DongGuk University Ilsan Oriental Hospital and Dongshin University Gwangju Oriental Hospital. The number of participants required was calculated from the data of a previous, relevant study. These patients will be randomly allocated into acupuncture treatment or artificial tear groups. Either 17 acupuncture points (bilateral BL2, GB14, TE 23, Ex1, ST1, GB20, LI4, LI11 and single GV23) will be used 3 times a week or disposable artificial tear drops (Refresh Plus?, ALLERGAN) will be provided for use at least once a day for 4 weeks. The ocular surface disease index (OSDI), tear film break-up time (TFBUT), Schirmer I test, visual analogue scale (VAS) for self-assessment of ocular discomfort, general assessment (by both acupuncture practitioners and participants) and quality of life (QOL) through the Measure Yourself Medical Outcome Profile-2 (MYMOP-2) will be assessed for approximately 3-months for each study participant. In addition, qualitative study and cost-effectiveness of acupuncture treatment will be conducted.ClinicalTrials.gov (Identifier: NCT01105221).Dry eye is not a life-threatening disease, but it is one of the most common and irritating conditions in ophthalmology. Because of recent data on both the pathological mechanism and aetiology, the definition of dry eye has been changed from simple ocular discomfort (related to the deficiency or hyper-evaporation of tears) to a multifactorial disease (with ocular discomfort and visual disturbances, which are related to tear-film instability and both the hyper-osmolarity and chronic inflammation of the ocular surface) [1]. The overall prevalence has been reported to be between 5 and 35 percent in different populations [2]. The incidence is now increasing more rapidly than other ophthalmologic diseases such as cataracts, retinal disease and glaucoma [3]. This may b

Trials , 2009, DOI: 10.1186/1745-6215-10-112
Abstract: A randomised, patient-assessor blinded, sham (non-acupuncture point, shallow acupuncture) controlled study was established. Participants allocated to verum acupuncture and sham acupuncture groups will be treated three times weekly for three weeks for a total of nine sessions per participant. Seventeen points (GV23; bilateral BL2, GB4, TE23, Ex1 (Taiyang), ST1 and GB20; and left SP3, LU9, LU10 and HT8 for men, right for women) have been selected for the verum acupuncture; for the sham acupuncture, points have been selected that do not coincide with a classical acupuncture point and that are located close to the verum points, except in the case of the rim of the eye. Ocular surface disease index, tear film breakup time, the Schirmer I test, medication quantification scale and general assessment of improvement will be used as outcome variables for evaluating the effectiveness of acupuncture. Safety will also be assessed at every visit. Primary and secondary outcomes will be assessed four weeks after screening. All statistical analyses will be performed using analysis of covariance.The results of this trial will be used as a basis for clarifying the efficacy of acupuncture for dry eye.ClinicalTrials.gov NCT00969280.Dry eye is one of the most frequently occurring opthalmological health problems worldwide. The prevalence of dry eye is estimated to be in the range of 5% to 35% and its incidence has recently been increasing [1]. According to a recent survey, over 20% of outpatients in ophthalmologic clinics in Korea were diagnosed with dry eye [2]. The burden of dry eye involves not only problems with common activities such as reading, carrying out professional work, using the computer, watching television, and driving [3], but also widespread limitations in the activities of daily life, bodily pain, discomfort and lower energy and vitality [4].Currently, the use of artificial tears and lifestyle modifications are the most common choices in management of patients with mild

Trials , 2011, DOI: 10.1186/1745-6215-12-146
Abstract: We recruited 32 participants (21 in the wet-cupping group and 11 in the waiting-list group) who had been having PNSLBP for at least 3 months. The participants were recruited at the clinical research centre of the Korea Institute of Oriental Medicine, Korea. Eligible participants were randomly allocated to wet-cupping and waiting-list groups. Following the practice of traditional Korean medicine, the treatment group was provided with wet-cupping treatment at two acupuncture points among the BL23, BL24 and BL25 6 times within 2 weeks. Usual care, including providing brochures for exercise, general advice for PNSLBP and acetaminophen, was allowed in both groups. Separate assessors participated in the outcome assessment. We used the 0 to100 numerical rating scale (NRS) for pain, the McGill Pain Questionnaire for pain intensity (PPI) and the Oswestry Disability Questionnaire (ODQ), and we assessed acetaminophen use and safety issues.The results showed that the NRS score for pain decreased (-16.0 [95% CI: -24.4 to -7.7] in the wet-cupping group and -9.1 [-18.1 to -0.1] in the waiting-list group), but there was no statistical difference between the groups (p = 0.52). However, the PPI scores showed significant differences between the two groups (-1.2 [-1.6 to -0.8] for the wet-cupping group and -0.2 [-0.8 to 0.4] for the waiting-list group, p < 0.01). In addition, less acetaminophen was used in the wet-cupping group during 4 weeks (p = 0.09). The ODQ score did not show significant differences between the two groups (-5.60 [-8.90 to -2.30] in the wet-cupping group and -1.8 [-5.8 to 2.2] in the waiting-list group, p = 0.14). There was no report of adverse events due to wet-cupping.This pilot study may provide preliminary data on the effectiveness and safety of wet-cupping treatments for PNSLBP. Future full-scale randomised controlled trials will be needed to provide firm evidence of the effectiveness of this intervention.ClinicalTrials.gov: (Identifier: NCT00925951)Date of tr

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0036638
Abstract: Purpose To evaluate the effects of acupuncture compared to a control group using artificial tears. Methods Setting & design: multicenter randomised controlled trial (three local research hospitals of South Korea). Study Population: 150 patients with moderate to severe dry eye. Intervention: Participants were randomly allocated into four weeks of acupuncture treatment (bilateral BL2, GB14, TE 23, Ex1, ST1, GB20, LI4, LI11 and single GV23) or to the artificial tears group (sodium carboxymethylcellulose). Main Outcome Measure(s): The ocular surface disease index (OSDI), tear film break-up time (TFBUT), Schirmer Ι test, visual analogue scale (VAS) for self-assessment of ocular discomfort, general assessment (by both acupuncture practitioners and participants) and quality of life (QOL) through the Measure Yourself Medical Outcome Profile-2 (MYMOP-2). Results There was no statistically significant difference between two groups for the improvement of dry eye symptoms as measured by OSDI (MD ?16.11, 95% CI [?20.91, ?11.32] with acupuncture and ?15.37, 95% CI [?19.57, ?11.16] with artificial tears; P = 0.419), VAS (acupuncture: ?23.84 [?29.59, ?18.09]; artificial tears: ?22.2 [?27.24, ?17.16], P = 0.530) or quality of life (acupuncture: ?1.32 [?1.65, ?0.99]; artificial tears: ?0.96 [?1.32, ?0.6], P = 0.42) immediately after treatment. However, compared with artificial tears group, the OSDI (acupuncture: ?16.15 [?21.38, ?10.92]; artificial tears: ?10.76 [?15.25, ?6.27], P = 0.030) and VAS (acupuncture: ?23.88 [?30.9, ?16.86]; artificial tears: ?14.71 [?20.86, ?8.55], P = 0.018) were significantly improved in the acupuncture group at 8 weeks after the end of acupuncture treatment. TFBUT measurements increased significantly in the acupuncture group after treatment. Conclusions Acupuncture may have benefits on the mid-term outcomes related to dry eye syndrome compared with artificial tears. Trial registration ClinicalTrials.gov NCT01105221.

Jong-In Kim, Myeong Soo Lee, So-Young Jung, Jun-Yong Choi, Sanghoon Lee, Jeong-Min Ko, Hong Zhao, Jiping Zhao, Ae-Ran Kim, Mi-Suk Shin, Kyung-Won Kang, Hee-Jung Jung, Tae-Hun Kim, Baoyan Liu, Sun-Mi Choi
Trials , 2009, DOI: 10.1186/1745-6215-10-54
Abstract: This study consists of a multi-centre (two centres in Korea and two centres in China), randomised, controlled trial with three parallel arms (active acupuncture, sham acupuncture, and waitlist group). The active acupuncture and sham acupuncture groups will receive real or sham acupuncture treatment, respectively, three times per week for a total of 12 sessions over four weeks. Post-treatment follow-up will be performed a month later to complement these 12 acupuncture sessions. Participants in the waitlist group will not receive real or sham acupuncture treatments during this period but will only be required to keep recording their symptoms in a daily diary. After four weeks, the same treatment given to the active acupuncture group will be provided to the waitlist group.This trial will provide evidence for the effectiveness of acupuncture as a treatment for persistent allergic rhinitis. The primary outcome between groups is a change in the self-reported total nasal symptom score (i.e., nasal obstruction, rhinorrhea, sneezing, and itching) from baseline at the fourth week. Secondary outcome measures include the Rhinitis Quality of Life Questionnaire score and total non-nasal symptom score (i.e., headache, itching, pain, eye-dropping). The quantity of conventional relief medication used during the follow-up period is another secondary outcome measure.Current Controlled Trials ISRCTN90807007Allergic rhinitis (AR) is a highly prevalent major chronic respiratory disease. It significantly impacts quality of life (QoL) and creates an economic burden. AR can be classified as intermittent or persistent allergic rhinitis (PER), as described by the recent 'Allergic Rhinitis and its Impact on Asthma (ARIA)' guidelines [1]. The conventional treatment of AR symptoms, such as nasal obstruction, rhinorrhea, sneezing, and itching, includes the use of intranasal corticosteroids, oral anti-histamines with or without decongestants, immunotherapy, and education [2].
