In order to understand the role of mec regulator genes in the evolution of methicillin-resistant S. aureus (MRSA), the distribution of the mec regulator genes among the 66 clinical isolates of MRSA was analysed. And also the correlation between gene mutation and degree of phenotypic expression of resistance was studied. Fifty strains carried whole mec regulator region, while the mecI gene and nearly half of the 3'-end of the mecR#l gene were deleted in fifteen strains. The mecRl MS gene was detected among all of the mecA carried strains, but the mecRl PB gene was carried by 77% of the MRSA strains. At least a portion of the 5'-end region of the mecRl gene was carried by all MRSA strains tested. Forty-seven strains were finally confirmed to have mecI gene and each mecI gene of above strains was sequenced for identification of the relationship between repressor function of mecI gene on mecA transcription and MIC level of methicillin. Point mutations were detected in 11 strains of 47 strains. In 8 strains, there was one nucleotide substitution (C to T at position 202) that produced a new termination codon at position 201. In 3 strains, one nucleotide substitution from G to T at position 43 caused an amino acid substitution from Val to Phe. The MIC of methicillin of strains carrying mutated mecI genes ranged 256 ug/ ml to 1024 ug/ml. Transcription level of amplified cDNA corresponding to mecA was determined by the method of RT-PCR of extracted RNA. Total RNA was extracted from two strains with mutated mecI gene and a strain with intact mecI gene. Deletional loss or the mutational inactivation of the mecI gene did not affect the level of mecA transcription. Role of mecI gene as a strong repressor function on mecA gene seemed to be skeptical.

Pseudoatrophoderma colli is a symptomless, persistent, persistent, pigmentary disorder involving the neck and upper thorax first described by Becker and Muir in. 1934 The lesion is usually localized to the neck and upper part of the thorax. It consists of macules or papules which show pigmentation or papules which show pigmentation or depigmentation and look atrophic. Histological examination shows hyperkeratosis, hypogranulosis, focal acanthosis and perivascular lymphocytic infiltration. We present herein a case of pseudoatrophoderma colli which showed symptomless, mottled, pigmentated macules involving the neck clinically and compatible findings histopathologically.

BACKGROUND: The size of the baseplate used in reverse total shoulder arthroplasty (RTSA) tends to be larger than the average size of the glenoid in the Korean population. The mismatch between the sizes of the baseplate and the patient's glenoid may result in improper fixation of the glenoid baseplate. This in turn may lead to the premature loosening of the glenoid component. Thus, we evaluated the short-term results of using a 25-mm baseplate in RTSA. METHODS: Seventeen patients with cuff tear arthropathy underwent RTSA with a 25-mm baseplate. The mean age of the patients was 70.1 years, and the mean follow-up period was 14.0 months. We evaluated clinical outcomes preoperatively and postoperatively: the range of shoulder motion, the American Shoulder and Elbow Surgeons (ASES) score, and the Korean Shoulder Society (KSS) score. RESULTS: We found that the mean ASES score and KSS improved from 35.0 to 74.4 (p<0.001) and from 46.9 to 71.8 (p<0.001) with RTSA. The mean forward elevation and abduction, external rotation also improved from 78.6degrees to 134.3degrees (p<0.05) and from 66.6degrees to 125.0degrees (p<0.05), from 20.2degrees to 28.4degrees (p=0.43). Postoperative complications were seen in 12% of patients, but neither the loosening of the glenoid baseplate nor inferior scapular notching were observed. CONCLUSION: In sum, the results of using a 25-mm baseplate in RTSA were similar to those of previous reports. Even though the outcomes are those of a short-term follow-up, neither the loosening of the glenoid baseplate nor the scapular notching were observed.

BACKGROUND: Metabolic syndrome increases the risk for cardiovascular diseases and type 2 diabetes mellitus. Many studies have revealed that eating frequency influences the total serum cholesterol level, glucose tolerance and obesity. Hypothesizing that an increase in eating frequency decreases the prevalence of metabolic syndrome with total energy intake adjusted, we evaluated the association between eating frequency and the risk of metabolic syndrome in Koreans aged more than 20 years old. METHODS: We used the data from the 2005 Korean National Health and Nutrition Examination Survey. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III and the Asia-Pacific regional obesity guidelines. To examine the association of metabolic syndrome with eating frequency, snack frequency and meal frequency, we performed multiple logistic regression analysis adjusting for age, sex, physical activity, daily caloric intake, smoking and drinking. RESULTS: Meal frequency was associated with metabolic syndrome in the 20-45 years group (P=0.011). Eating frequency was significantly related with metabolic syndrome in the group aged more than 45 years (P=0.025). Within the subgroup of subjects more than 45 years who had one or two meals a day, snack frequency showed a significant association with metabolic syndrome (P=0.038). CONCLUSIONS: These results suggest that a decreased eating frequency is associated with a risk of metabolic syndrome, although the causal relationship is not exactly known. It would be useful to pursue this question through further studies.
