PURPOSE: This study was aimed to analyze the incidence and the anatomical distributions of HME (Hereditary Multiple Exostoses) on upper limbs and its related change in alignment of the upper limbs in HME patients. MATERIALS AND METHODS: Thirty eight patients who had been diagnosed HME between 2001 and 2009, were categorized into two groups; (1) group A (1-2 involvements); (2) group B (> or =3 involvements). We checked the carrying angle, VAS (Visual Analogue Scale), limitations in daily activities, cosmetic satisfaction according to the number of exostoses invasion. RESULTS: Among the 38 patients, 23 patients (43 cases) had exostoses in the upper limbs. The locations of exostoses in the upper limbs were proximal humerus in 33 cases (30%), distal ulna in 31 cases (28.2%), and distal radius in 24 cases (21.8%). The carrying angle of group A and B was 10.7degrees, 13.8degrees, VAS was 1.3, 3.5, and the limitations in daily activities was 7.3, 6.6 of 8 points. The cosmetic satisfactory cases were 13 and 10 cases, respectively. CONCLUSION: The deformity in upper limbs was observed in 65% of the HME patients. As the number of invasion increases, carrying angle and VAS were increased but limitations in daily activities and cosmetic satisfaction were decreased.

The accreditation process (AccP) is both an opportunity and a burden for medical schools—which one it becomes depends on how medical schools recognize and utilize the AccP. In other words, if a medical school recognizes the AccP only as a formal procedure or as a means for continuing medical education, it will be a burden for the medical school. However, if a medical school recognizes the real and positive value of the AccP, it can be both an opportunity and a tool for developing medical education. The educational value of the AccP is to improve the quality, equity, and efficiency of medical education, along with increasing the options of choice. In order for the AccP to contribute to the development of medical education, accrediting agencies and medical schools must first be recognized as part of an “educational alliance” working together towards common goals. Secondly, clear guidelines on the accreditation standards should be periodically reviewed and shared. Finally, a formative evaluation using self-evaluation as a system that can utilize the AccP as an opportunity to develop medical education must be introduced. This type of evaluation system could be developed through collaboration among medical schools, academic societies for medical education, and the accrediting authority.

The accreditation process is both an opportunity and a burden for medical schools in Korea. The line that separates the two is based on how medical schools recognize and utilize the accreditation process. In other words, accreditation is a burden for medical schools if they view the accreditation process as merely a formal procedure or a means to maintain accreditation status for medical education. However, if medical schools acknowledge the positive value of the accreditation process, accreditation can be both an opportunity and a tool for developing medical education. The accreditation process has educational value by catalyzing improvements in the quality, equity, and efficiency of medical education and by increasing the available options. For the accreditation process to contribute to medical education development, accrediting agencies and medical schools must first be recognized as partners of an educational alliance working together towards common goals. Secondly, clear guidelines on accreditation standards should be periodically reviewed and shared. Finally, a formative self-evaluation process must be introduced for institutions to utilize the accreditation process as an opportunity to develop medical education. This evaluation system could be developed through collaboration among medical schools, academic societies for medical education, and the accrediting authority.

BACKGROUND: We previously demonstrated that a GRE/TRE composite sequence, which is located between 200 bp and 220 bp relative to the transcriptional start site of rat TRH gene, is responsible for the dexamethasone (DEX)- and TPA-induced transcriptional activation, and the transcriptional activation by DEX is mediated by interaction between glucocorticoid receptor (GR) and a TRE-binding transcriptional factor such as c-Jun. However, a non-specific binding with the transciption factors can not be excluded as the mutants used in the previous report could not inhibit the binding of GR and c-Jun completely, and it remains unclear which one of the two TRE-like sequences is critical for the interaction of the two transcription factors. METHODS: Luciferase expressing plasmids that contain a part of rat TRH promoter including the composite GRE sequence or its mutants were transfected into HeLa cells by Fugene 6. After the cells were incubated overnight with DEX or/and TPA, the luciferase activity was measured in a chemiluminometer. A gel retardation assay was performed after binding of the labeled composite sequence or its mutants with GR and c-Jun. RESULTS: DEX and TPA increased the transcriptional activity of the wild type composite sequence by 3 folds and 4 folds, respectively, and the combined stimulation increased the activity by 10 folds. The mutants of which all 6 nucleotides of the GRE half site were replaced and removed almost did not bind to GR and eould not enhance the transcriptional activity at all in response to DEX. The GRE-deleted mutant bound to c-Jun with a remarkably lower affinity and showed a lower response to TPA, whereas the GRE-replaced mutant bound to c-Jun with a similar affinity and showed a similar response to TPA compared to those of the wild type. In response to the combined simulation with DEX and TPA, the mutants showed 30-40% of the trancriptional activity of the wild type. Basal transcriptional activity of all the TRE mutants was significantly lower than that of the wild type. While they almost could not bind to c-Jun, their binding affinity to GR was comparable to that of the wild type. Whereas the DEX- and TPA-induced transcriptional activity of 5 TRE mutant was 10% and 15% of that of the wild type, it responded to those agents in a similar pattern as the wild type. The 3 TRE mutant and the mutant of both TRE sites did not respond to DEX and TPA. The GRE-deleted mutant hardly formed the DNA-protein complex as did the wild type, while the GRE -replaced mutant could form the complex in a less amount with nuclear extract of HeLa celL CONCLUSION: These results suggest that GRE/TRE composite sequence of rat TRH gene specifically binds to GR and c-Jun, providing a site for interaction between the two transcription factors, and that both TRE sites play an important role in basal transcription, and that the 3 TRE site is more critical in the interaction between GRE and TRE for DEX-induced transcriptional activation.

BACKGROUND: We previously demonstrated that the promoter of rat TRH gene has GRE half site (TGTTCT) between -210 bp and -205 bp flanking with similar sequences of TPA response element (TRE), TAGTCA, at a distance of several base pairs from the GRE half site. It promps us to hypothesize that this composite GRE/TRE sequence can provide a site for interaction between glucocorticoid receptor (GR) and c-Jun. Thus, we investigated whether the composite sequence mediates transcriptional regulation induced by dexamethasone (DEX) and 12-O-tetradecanoyl phobol-13-acetate (TPA), and whether it binds GR and c-Jun. METHODS: A luciferase expressing plasmids that contain a part of rat TRH promoter including the composite sequence or their mutants were transfected into HeLa cells by Fugene 6. After the cells were incubated overnight with DEX and TPA, the luciferase activity was measured in a chemiluminometer. A gel retardation assay was performed after binding of the labeled composite sequence or its mutants with GR and c-Jun. RESULTS: DEX increased the transcriptional activity of the plasmid containing the wild type GRE by 2.5 folds, and TPA increased the transcriptional activity by 4 folds. The simultaneous stimulation with DEX and TPA synergistically increased the transcriptional activity by 10 folds. Two mutants whose GRE half sits were altered showed no responses to DEX, and suppressed the TPA-induced or both agents-induced transcriptional activity by 50%. Two mutants whose TRE-like sites were altered suppressed the DEX-induced transcriptional activity by 20%, TPA-induced trarptional activity by 25%, and both agents-induced transcriptional activity by 50%. Gel retardation assay showed that the composite sequence fonned a complex with GR and its mutants bound to GR with remarkably less affinity. c-Jun also bound to the composite sequence to form two cornplexes with less affinity compared to the AP-1 consensus sequence. The mutants of the TRE-like sequence bound to c-Jun with a significantly lower affinity compared to that of the wild type. Simulateous binding of the composite sequence with GR and c-Jun did not form any larger complex. The complex of GR and the composite sequence was much smaller than that formed by c-Jun, suggesting that GR binds to the composite sequence as a monomer. CONCLUSION: These results suggest that the composite sequence of GRE half site and TRE-like site on the promoter of rat TRH gene provides binding sites for GR and c-Jun, which mediate the interaction between two signal transduction pathways.

PURPOSE: The aim of this study was to determine the role of renal ultrasonography in neonates with isolated preauricular tags. METHODS: We performed a retrospective study of 10,997 newborn infants delivered from January 1995 to June 2003 in Wonkwang University Hospital. Nineteen newborns born with isolated preauricular tags were assessed for renal anomalies by performing renal ultrasonography within one week after birth. The study group was compared with a control group of 25 healthy neonates without preauricular tags during the same period, also using renal ultrasonography. RESULTS: Preauricular tags were detected in 19 of 10,997(0.17%) neonates; 57.9% were found on the right side. Renal anomalies in neonates with isolated preauricular tags were detected in four infants (21.1%); this incidence was higher, but was not significant, compared with the control group. Types of anomalies were mild hydronephrosis of grade 1(3 cases) and 2(1 case) which were normalized within one year. CONCLUSION: Routine renal ultrasonography is not recommended for newborn infant with isolated preauricular tags.

Torture is an extreme life stressor which increases the risk of serious psychological and physical sequelae of victims. Despite Geneva declaration, Amnesty International reports that torture remains as human rights issue in many sites of the world. Even in Korean peninsula, torture is a serions human rights issue. This paper is a critical review on torture; to describe its methods and effects, the assessment of psychological and physical sequelae, and its treatment. Torture also affects survivor's family. The more prolonged, repeated, and unpredictable the experience of torture is, the more serious psychiatric consequences are likely. Psychological responses and sequelae include not only symptoms of Posttraumatic Stress Disorder (PTSD), but also depression, personality changes, somatoform disorders and others. Diagnositic terms such as complex PTSD or torture syndrome have been used to denote the complexity of torture trauma. Treatment is a combination of pharmacotherapy, cognitive-behavioural therapy, guidance for of socialre readaptation. Ensuring safety and trust between survivors and medical staffs is important. Torture prevention is to expose the facts particularly health data to the public, and collaborate with international organizations fighting against torture. Preventive interventions is linked to a change in the underlying socio-political causes and to the creation of necessary conditions for human rights and development at the level of society.
