임정기 大韓神經精神醫學會 2003 신경정신의학 Vol.42 No.5

A journal indexed by the Institute for Scientific Information for SCI-expanded and by the National Library of Medicine for Index Medicus/MEDLINE is important to be recognized internationally. The Korean journal of Radiology has been indexed in the database of the SCI-expanded since 2001 and Medicus/MEDLINE since 2000. The criteria for journal evaluation and selection by the National Library of Medicine include quality of editorial work, production quality, and quality of content. Most of the candidate journals contain reasonably good quality in editorial work and production. Thus, we believe that the quality of content is the most important criteria for the journal selection. To maintain a good quality of content, selection of the manuscript containing originality and scientific merits is imperative in review process. Highly selected, small number of articles per issue would be a wise editorial policy for a journal to be indexed by the well-known database.

For the initial step of quality assurance program for the reading of pneumoconiosis, we developed 85 simple chest P-A films by stepwise panel readings of 8 highly qualified radiologists. Intra-reader reliability(overall kappa value) for the pneumoconiotic findings of 76 films except films for differential diagnosis by 6 radiologists participating in the panel readings was as follows: 0.44 and 0.73 in profusion by complete and short classification, 0.45 and 0.40 in primary and secondary small opacity, 0.62 in extent of small opacity, 0.67 and 0.22 in costophrenic angle(CPA) obliteration and diffuse pleural thickening(DPT). Interreader reliability was as follows: 0.40 and 0.67 in profusion by complete and short classification, 0.48 and 0.43 in primary and secondary small opacity, 0.54 in extent of small opacity, 0.60 and 0.30 in CPA obliteration and DPT. Pneumoconiotic findings of the 44 films selected from the above 76 films were compared with those of 39 radiologists working in agencies for specific health screening, agency for pneumoconiosis, and other university hospitals. According to the category, profusion(excluding 0/0 category) agreed completely in 10-40% of the corresponding small opacity and 55-80% of the large opacity by complete classification. Within 1 minor category 55.85% of films agreed. By short classification it agreed in 50-80% and 91.2% of small and large opacity respectively. Shape and size of primary and secondary small opacity agreed completely in 41.0% and 23.2%, and extent of small opacity agreed in 47.9%. Only in the films read as pneumoconiosi by readers, 51.3% and 29.8% of primary and secondary small opacity agreed in shape and size, and 60.4% in extent. In CPA obliteration and DPT, 81.8% and 78.3% of the corresponding films agreed respectively. Considering the above results, it is necessary to develop educational and quality assurance program for increase of reading agreement.

This study conducted a result analysis on operation of 26 Rural Community Sewage Treatment Plant (RCSTP) newly constructed in Yeong-yang, Bong-hwa and An-dong areas which are located at the uper region of An-dong Dam and Im-ha Dam. Based on operation result, an analysis on characteristics of sewage in each areas and the treatment efficiency of the installed treatment process was conducted. The result of analysis on characteristics of sewage has shown the difference in concentration of the sewage according to area characteristics. Sewage in areas with frequent occurrence of agricultural water and livestock wastewater had high concentration. It is important to select the most suitable treatment process when selecting a treatment process for RCSTP according to properties of sewage in each area. As a result of operation, the disposal efficiency for organic matter and suspended solids was stable with less fluctuation, but the disposal efficiency for nitrogen and phosphorus showed high fluctuation. This signifies that it is necessary to pay attention to operation condition management of aitrogen and phosphorus when operating RCSTP.

Asbestos industry has been in operation over 60 years in Korea. However, the prevalence of asbestosis has not been yet reported. With rapid turn-over of workers, previous cross-sectional studies of current workers on the job could not find cases with exposures long enough for the development of asbestosis. This study was done to evaluate asbestosis prevalence of those worksites with operation history of more than 20 years. In total, 139 workers from 5 worksites were examined. Asbestos industries covered in the study include 2 asbestos textile, 1 brake lining, and 2 ship repairing worksites. Chest x-ray was taken from all workers and read by two experts familiar with pneumoconiosis classification according to 1980 ILO guidelines. Those with findings compatible with asbestosis were further ckecked with high resolution computerized tomography (HRCT). Pulmonary function tests were done according to ATS guidelines, and occupational and previous medical history was taken through a standardized interview. Air-borne asbestos was measured according to NIOSH method 7400. The air-borne asbestos concentrations ranged from 0.2-1.3 f/cc for asbestos textile, from 0.7-1.0 f/cc for brake lining, and from 6.3-7.8 f/cc during asbestos removal at ship repairing worksite. Of the 139 workers 25 had abnormal chest radiographic findings, and 10 of them had findings compatible with pneumoconiosis. When work history and current asbestos measurements were accounted, 9 workers who had more than 10 years of asbestos exposure history showed chest radiographic findings of pneumoconiosis with Finally, 4 workers showed finding of pulmonary fibrosis and/or pleural thickening at HRCT, and 2 of them had restrictive lung function changes. The study results showed that, among 139 subjects, there were 4(3%) definite asbestosis cases confirmed with HRCT. The prevalence of probable asbestosis was 7% for 10-14 years of exposure, 13% for 15-19 years of exposure, and 23% for 20 or more years of exposure. The prevalence of compensable asbestosis with abnormal lung function was 4-6% for those with 15 or more years of exposure.

Objective. To estimate the cardiovascular (CV) and gastrointestinal (GI) risks of etoricoxib in the treatment of osteoarthritis (OA) compared to a placebo and other non-steroidal anti-inflammatory drugs (NSAIDs). Methods. A systematic review of randomized, controlled trials (RCTs) of etoricoxib were performed. Bayesian network meta-analysis was used over a duration of 12 weeks. The incidence of CV and GI events for a duration ≥26 weeks were also tabulated and presented using descriptive statistics. Results. From this search, 10 studies were identified. Of these, 6 and 5 RCTs that measured the CV and GI events at 12 weeks were included in meta-analysis. They showed that etoricoxib did not increase the CV events compared to the placebo or NSAIDs during the 12 week period (odds ratio [OR]=0.59 compared to celecoxib, OR=0.89 with ibuprofen, OR=0.70 with placebo, and OR=2.16 with naproxen). The risk of GI events was comparable to that of most comparators, with the exception of naproxen, which had a significantly lower risk of GI events (OR=0.18) during the 12 week period. For a duration ≥26 weeks, the incidence of CV and GI events with etoricoxib increased with increasing duration. Conclusion. Etoricoxib is an alternative short-term treatment option for OA, showing comparable CV and GI complications to other NSAIDs. Nevertheless, further studies will be needed to elucidate the long-term safety of etoricoxib in the treatment of OA. (J Rheum Dis 2017;24:293-302)

<P> Conclusion. This study demonstrated differential gene expression profiles in salicylate ototoxicity with oligonucleotide microarray. This study may also provide basic information on candidate genes associated with hearing loss and/or tinnitus or recovery after salicylate-induced cochlear dysfunction. Objectives: Salicylate ototoxicity is accompanied by temporary hearing loss and tinnitus. The purpose of the present study was to evaluate the gene expression profiles in the mouse cochlea with salicylate ototoxicity using DNA microarray. Materials and methods: The subject mice were injected intraperitoneally with 400 mg/kg of sodium salicylate; an approximate 30 dB threshold shift that was observed by auditory brainstem response was achieved 3 h after an injection of sodium salicylate and the hearing threshold returned to within normal range at 3 days. Differential gene expression profiles at 3 h after salicylate injection in comparison to the normal cochlea were analyzed with DNA microarray technology. Results: No ultrastructural changes in the mice cochlea were observed by TEM at 3 h after salicylate injection. Microarray revealed that 87 genes were up-regulated twofold or more in the mouse cochlea with salicylate ototoxicity in comparison to the normal cochlea. Among these genes, increased expression levels of 30 functional genes were confirmed by semi-quantitative RT-PCR.</P>

Gi Jung Im,Ha Kyun Kim,신영기,Jiwon Chang,정학현,Jeong Hoon Lee 대한청각학회 2011 Journal of Audiology & Otology Vol.15 No.1

Background and Objectives: Adhesion of middle ear and mastoid cavity after mastoidectomy represents a potential source of surgical failure. GUARDIX-SL®, absorbable anti-adhesive material, which is composed of sodium hyaluronate and sodium carboxymethyl cellulose, is an effective agent that widely used as a surgical adjuvant to decrease adhesion in the surgery. Therefore, we evaluated the clinical efficacy of the GUARDIX-SL® for the prevention of adhesion after mastoidectomy. Subjects and Methods: This study was randomized and double-blinded. Conventional intact canal wall mastoidectomy was conducted in both control (n=14) and study group (n=10). To avoid bias because of different surgeons, we only included patients who were operated on by one surgeon. In the study group, 1.5 g GUARDIX-SL® was applied in the mastoid cavity at the end of mastoidectomy. To evaluate anti-adhesive effect of GUARDIX-SL®, the volume of aerated area in the mastoid cavity was calculated and compared with temporal bone computed tomography performed at preoperatively and postoperatively. Besides, to assess the success of operation, pure tone audiometry was also performed at preoperatively and postoperatively. Results: The volume of aerated area of mastoid cavity after mastoidectomy was more increased in GUARDIX-SL® group, but was not statistically significant in the GUARDIX-SL® group than the control. And all results of pure tone audiometry satisfied the criteria of successful operation which has been suggested by Otological Society of Korea. Conclusion: The results suggest that GUARDIX-SL® may be an efficacious and safe material in decreasing the incidence of adhesion after mastoidectomy.
