Purpose: This study aimed to identify the colonization rate of carbapenem-resistant Enterobacteriaceae (CRE), the characteristics of CRE isolates, and risk factors for CRE colonization in patients transferred to the general wards of a small/medium-sized hospital. Methods: This retrospective study was conducted on patients who underwent CRE culture tests within 24 hours of admission among patients transferred to a small/medium-sized hospital. Forty-seven patients confirmed as positive for CRE were classified as belonging to the patient group. For the control group, 235 patients (five times the number of the patient group) were matched by sex, age, and diagnosis, and then selected at random. Data were analyzed using descriptive analysis and multiple logistic regression analysis. Results: The CRE colonization rate was 5% (47 out of 933 patients), and Klebsiella pneumoniae (68.0%) was the most common isolate of CRE. The positivity rate of carbapenemase-producing Enterobacteriaceae was 61.7%. The risk factors for CRE colonization included renal disease (odds ratio [OR]=4.93; 95% confidence interval [CI], 1.49-16.31), heart disease (OR=3.86; 95% CI, 1.35-11.01), indwelling urinary catheters (OR=4.43; 95% CI, 1.59-12.36), and cephalosporin antibiotic use (OR=8.57; 95% CI, 1.23-59.60). Conclusion Having a comorbid renal or cardiac disease, an indwelling urinary catheter, or a history of exposure to cephalosporin antibiotics could be classified as risk factors for CRE colonization in patients transferred to small and medium-size hospitals. It is necessary to perform active infection control through proactive CRE culture testing of patients with risk factors.

Nevoid melanoma is a very rare histological subtype of vertical growth phase melanoma. Histologically, it mimics benign nevus and thus may lead to an erroneous diagnosis. We report a case of nevoid melanoma arising in a 53-year-old American woman. High index of suspicion and evaluation of cytologic atypia with ancillary tests may help in establishing the diagnosis.

This study was carried out to compare parents' satisfaction with school foodservice between participants and non-participants of foodservice monitoring. Surveys were conducted in six schools that implemented foodservice monitoring. In these schools, 126 participants and 167 non-participants were surveyed. The results were as follows: The participant group was more satisfied with taste (participation 3.63, non-participation 3.20), quantity (participation 3.69, non-participation 3.20), and menu composition (participation 3.67, non-participation 3.16) than the non-participant group. In addition, the satisfaction level of the participant group (3.74) was significantly higher than that of the non-participant group (3.24) (p<0.01). It was also indicated that the overall level of trust toward the foodservice operation was significantly higher in the participant group (3.90) than in the non-participant group (3.32) (p<0.001). After participating in monitoring, 74.8% of the parents changed their perception on school foodservice and 84.7% of them became to have more positive views. In conclusion, we found that parents' participation in school foodservice monitoring had positive effects on their satisfaction and perceptions on school foodservice.

BACKGROUND: Insulin-like growth factor II mRNA-binding protein 3 (IMP3) has been reported as a prognostic biomarker in various cancers. To validate IMP3 as a prognostic biomarker in renal cell carcinoma (RCC), we investigated the expression of IMP3, p53, and Ki-67, and their associations with clinicopathologic outcomes. METHODS: We studied 148 clear cell RCCs (CCRCCs) from patients who underwent radical nephrectomy. The expression levels of IMP3, p53, and Ki-67 were assessed by immunohistochemical staining and the clinical and pathologic parameters were retrospectively reviewed. RESULTS: Twenty-nine percent of CCRCCs expressed IMP3. Forty-one percent of IMP3-immunopositive tumors developed metastases, while only 11.4% of IMP3-negative tumors developed metastases (p<.001). A Kaplan-Meier curve showed that patients with IMP3-immunopositive tumors had lower metastasis-free survival and cancer-specific survival than did those with IMP3-immunonegative tumors (p<.001 and p<.001, respectively). Expression of high Ki-67 proliferation index was also associated with a higher metastatic rate. In the multivariate Cox regression analysis, pT stage and IMP3-positivity were independently associated with disease-specific survival. CONCLUSIONS: IMP3 is an independent prognostic biomarker for patients with CCRCC to predict metastasis and poor outcome.

Light chain deposition disease (LCDD) is characterized by the deposition of abnormal immunoglobulin light chains in many organs, including kidney. It is usually associated with multiple myeloma or other lymphoproliferative disorders. Myeloma usually occurs in old age and may develop after renal transplantation thus being categorized as posttransplant lymphoproliferative disease (PTLD). Renal LCDD usually presents with variable degree of proteinuria and renal insufficiency. The diagnosis of LCDD depends on histologic findings with detection of monoclonal immunoglobulin light chain. Histologically, it is characterized by nodular glomerulosclerosis. We report the first case of de novo LCDD associated with myeloma after renal transplantation in Korea. With advancing renal transplantation and increasing old aged renal recipients, myeloma or LCDD should be included in the differential diagnoses of renal recipient patients with deteriorating renal function.

Although the frequency of composite resin restoration in children is gradually increasing, there are insufficient researches about the rate of composite resin repair in children. The purpose of this study was to evaluate the repair rate of composite resin restorations in the permanent first molar in children under 12 years old. This study retrospectively analyzed 169 children treated with composite resin restoration in the permanent first molar from May 2014 to April 2015.According to the location of the tooth, the repair rate was higher in the mandible than maxilla and in the left than right. In the classification of restoration, the repair rate was the highest in the class II cavity, and the repair rate was the lowest in the restoration of the occlusal surface only. Repair rate in two years was 14.8%, and repair hazard ratio decreased with age. The most common reason of composite resin restoration replacement was the secondary caries (74.1%).Within the limits of study, the repair rate of children was higher than that of adult due to the characteristics of children. Therefore, dentists should understand these characteristics and try to reduce the repair rate of composite resin composite restorations.

The first permanent molars play a key role in maxillofacial development and occlusion. The purpose of this study is to investigate the characteristics and development stages of first molars with delayed eruption, and to evaluate their associations with congenital missing teeth. Eight-year-old patients who had delayed eruption in their first molars were classified into 75 patients with physical barriers and 77 patients without physical barriers. The development stages of the first and second molars in the delayed area were analyzed using Nolla method from the panoramic radiographs. The relationship between congenital missing teeth and delayed area was also investigated. Delayed eruption of first molars were more common in the maxilla alone. With the presence of physical barriers, male patients showed higher frequency in unilateral cases, while female patients had higher bilateral cases when there was no physical barrier. Delayed development of first molars were observed in delayed eruption area. In the absence of physical barriers, adjacent second molars were also developed slowly and the incidence of congenital missing teeth was high in delayed area. If first molars with delayed eruption are observed, clinical and radiographical follow-ups are necessary for the evaluation of their developmental stages and congenital missing teeth.

Endotracheal intubation sometimes leads to complications, particularly in patients with anticipated difficult intubation. The GlideScope is preferred because of its high success rate in cases with anticipated difficult intubation. However, complications during the process have been reported. Most minor injuries can be treated after early detection. However, treatment can be difficult if complications occur later. We report a patient who underwent an emergency tracheostomy due to a delayed airway obstruction caused by pharyngeal wall bleeding during intubation with a GlideScope.
