BACKGROUND: As many as several weeks of incubation may be necessary for the recovery of mycobacteria when conventional culture media are used. Previous studies evaluating Mycobacteria Growth Indicator Tube (MGIT) as a rapid for the growth and detection of mycobacteria from clinical specimens have been reported. We compared MGIT with Ogawa media for the recovery of mycobacteria from clinical specimens. METHODS: Ninety nine clinical specimens received in the laboratory of Wonju Christian Hospital from June to September 199 were used for this study. The specimens from nonsterile body sites were digested, decontaminated, and concentrated, for culture and Ziehl-Neelsen stain, and specimen were inoculated onto MGIT tube and 3% Ogawa egg medium, and cultured for 8 weeks. RESULTS: Of the 38 specimens culture-positive for mycobacteria, 3 grew isolates in MGIT medium only, 8 grew isolates in Ogawa media only, and 27 grew isolates in both media. Mean (median, range) times to detection of mycobacteria were 13.7 (5.5, 2-48) days with MGIT and 19.6 (18, 13-37) days with Ogawa (P>0.05). The number recovered with MGIT plus Ogawa media was 24 (63.2%) within 14 days of receipt of specimen, and 31 (81.6%) within 21 days. The contamination rates were 31 % for MGIT and 1 % for Ogawa media. CONCLUSIONS: MGIT appears useful to quickly detect and identify mycobacteria from clinical specimens. However, because the number of culture-positive specimen in MGIT was not greater than those recovered with Ogawa media, MGIT should be used in combination with solid media to reduce turnaround times and increase the isolation rate.

4.Development of Voice Prescription Service System using Fingerprint Authentication.
Journal of Korean Society of Medical Informatics 2004;10(2):201-210
Several years has passed to begin a new paradigm, job separation of a physician and a pharmaceutist, and a electronic prescription becomes common in large scale hospitals. However, the current prescription information system retains some problems such as insufficient patient usability, labor saving techniques and security. This paper is addressed to implement a voice prescription service system to solve the preceding problems. Several suggestions are presented to use voice recognition, voice compression, computer telephony and fingerprint authentication technology for the problems. Lab experimental results show that the processing time to identify drug items is reduced by 80% compared with conventional mouse usage and voice recording is more effective to direct drug usage in a complicated prescriptions. Online fingerprint authentication furnishes evidence of a patient permission and a physician prescription. This feature provides safer security than the current security system.

BACKGROUND: The erythromycin-resistance rate and phenotype distribution of Streptococcus propenes are quite different by geographical variation and study period. The aim of the present study was to determine the evolution of resistance to erythromycin and the frequency of erythromycin resistance phenotype of S. pyogenes isolated from Wonju Christian Hospital. METHODS: The minimal inhibitory concentrations (MICs) of erythromycin and clindamycin for 94 S. pyogenes isolated from clinical specimens between 1990 to 1998 were investigated. Double disk test of erythromycin (78microgram) and clindamycin (25microgram) were performed for 15 isolates of erythromycin resistant S. pyogenes to evaluate the erythromycin resistance phenotype. RESULTS: The resistance rates of 94 isolates of S. pyogenes were 16%(15/94) to erythromycin and 4%(4/94) to clindamycin. The frequency of erythromycin resistance phenotype in decreasing order were M phenotype (47%), inducible resistance phenotype (40%), and constitutive resistance phenotype (13%). Erythromycin-resistant S. pyogenes did not exist until 1993, but was isolated since 1994, and ranged from 14.0% to 24.0% during the period of 1994-1998. CONCLUSIONS: Our finding documents the emergence of high resistance rates to erythromycin in S. pyogenes at Wonju area since 1994. The M phenotype (47%) and inducible resistance phenotype (40%) account for the majority of erythromycin-resistant S. pyogenes.

OBJECTIVE: To evaluate the design characteristics of studies that evaluated the performance of artificial intelligence (AI) algorithms for the diagnostic analysis of medical images. MATERIALS AND METHODS: PubMed MEDLINE and Embase databases were searched to identify original research articles published between January 1, 2018 and August 17, 2018 that investigated the performance of AI algorithms that analyze medical images to provide diagnostic decisions. Eligible articles were evaluated to determine 1) whether the study used external validation rather than internal validation, and in case of external validation, whether the data for validation were collected, 2) with diagnostic cohort design instead of diagnostic case-control design, 3) from multiple institutions, and 4) in a prospective manner. These are fundamental methodologic features recommended for clinical validation of AI performance in real-world practice. The studies that fulfilled the above criteria were identified. We classified the publishing journals into medical vs. non-medical journal groups. Then, the results were compared between medical and non-medical journals. RESULTS: Of 516 eligible published studies, only 6% (31 studies) performed external validation. None of the 31 studies adopted all three design features: diagnostic cohort design, the inclusion of multiple institutions, and prospective data collection for external validation. No significant difference was found between medical and non-medical journals. CONCLUSION: Nearly all of the studies published in the study period that evaluated the performance of AI algorithms for diagnostic analysis of medical images were designed as proof-of-concept technical feasibility studies and did not have the design features that are recommended for robust validation of the real-world clinical performance of AI algorithms.

This is a case report of double primary malignant cancer occurred aynchronously in the stomach and lymphoid tissue, We report this case with review of literatures about the criteria, age distribution, predisposing factor, inidence, immunity and susceptibility of the primary malignant neoplasms. This case was a 59-year-old man who had Hodgkins disease and tubular adenocarcinoma, of the stomach. The diagnoais was verified histologically, Although multiple primary neoplaas are rare, the possibility of that must be conaidered seriously, And its hereditary predisposition and other predisposing factor muat be researched with enthuaiasm.

PURPOSE: Thoracic outlet syndrome (TOS) causes pain, paresthesia and muscle weakness in neck, upper back, and the upper limbs. The etiologic factor of TOS is associated with car accident. However, in many cases diagnosis of TOS is underdiagnosed and proper treatment was not performed, which consequently lead to chronic pain status. The authors report of cases diagnosed with TOS following car accidents in our hospital. MATERIALS AND METHODS: The retrograde study was conducted on 12 subjects who reported of neck pain and numbness following car accidents from January 2006 to June 2009. The study was conducted through telephone interviews and surveys to investigate the mechanism of the accidents, clinical manifestation, duration of the symptoms from diagnosis to treatment, treatment course and prognosis. RESULTS: Of the 12 subjects diagnosed with TOS, 9 of them were caused by whiplash injuries, and 3 of them were due to lateral side injuries. l0 of the subjects complained of cervical pain and upper limb paresthesia, 4 of the subjects had upper limb pain and 3 of them had only cervical pain as chief complaint. All of the subjects were underwent anterior scalene injections. A total of 8 subjects who were diagnosed with TOS within 4 weeks of the causal event showed symptom improvements while in the group of subjects who were diagnosed after 4 weeks after the injury, only 2 of the subjects showed recovery, 2 recovered for only a brief period of time after the scalene injection and showed chronic pain status. In the 2 cases initially diagnosed as cervical whiplash injury, the diagnosis of TOS was done in 3months and 6months after the accident respectively and the treaatment was delayed. CONCLUSIONS: There is high possibility of TOS after car accidents if cervical pain and numbness on the upper extremity are observed. Better clinical course and prognosis is expected in subjects who were diagnosed and treated within 4 weeks.
