DENV-1 was the most prevalent in the current study, and the ratio of DENV-2 genotype Cosmopolitan apparently increased since our previous study. These results suggest that genotypic diversity might be increasing in Thailand. (200 words).The aim of this study was to evaluate the prevalence and characteristics of carbapenemase-producing Enterobacteriaceae (CPE) from three tertiary-care Korean university hospitals between 2017 and 2018. Non-duplicated clinical isolates of Enterobacteriaceae revealing resistance to any carbapenem agents were collected prospectively from three tertiary university hospitals between 2017 and 2018. The presence of carbapenemase genes was detected by multiplex PCR and sequencing for blaKPC, blaVIM, blaNDM, blaIMP, blaOXA, and blaGES. Among the 690 carbapenem-resistant Enterobacteriaceae (CRE) isolates, 66.8% (N=461) were CPE. The species distribution of CPE was as follows K. pneumoniae was most common (75.9%), followed by E. coli (15.0%), C. freundii (4.6%), E. cloacae (2.6%), K. aerogenes (0.7%), and K. oxytoca (0.4%). All 11 CPE genes were detected, particularly KPC-2 (87.6%), NDM-1 (7.4%), NDM-5 (1.7%), KPC-3 (1.3%), OXA-232 (1.1%), and OXA-181 (1.1%). Six isolates produced two or three carbapenemases. Most of the carbapenemase-producing C. freundii were positive for NDM-1. We confirmed a high proportion of CPE among CRE with a high prevalence of KCP-2-producing K. pneumoniae and E. coli. We need to institute continuous surveillance to monitor the prevalence of CPE.We report the case of a 76-year-old woman whose infection was rapidly diagnosed as human granulocytic anaplasmosis (HGA) through a peripheral blood smear that showed characteristic intragranulocytic morulae. The smear was prepared on the day of hospitalization, which was 1-2 weeks before results were available from serology or the polymerase chain reaction (PCR). On the basis of the blood smear test, we started timely and appropriate antimicrobial treatment. The peripheral blood smear is known to have the lowest sensitivity when compared with serological or PCR tests for the diagnosis of HGA, but we suggest that the sensitivity of peripheral blood smear tests could be increased by employing experienced staff. The patient was confirmed as having HGA by PCR 7 days after the positive peripheral blood smear test, and 14 days later by serology. Morulae in neutrophils are an important diagnostic indicator of HGA, especially in febrile patients with a history of tick-bites or outdoor activities in rural areas.Primary hyperparathyroidism is usually caused by parathyroid adenoma; however, parathyroid carcinoma is a rare cause. https://www.selleckchem.com/products/bgb-15025.html We report a rare case of 74-year-old female of primary hyperparathyroidism caused by parathyroid carcinoma (PC) and coexisting multiple parathyroid adenomas. She was referred to our hospital for primary hyperparathyroidism and a suspected thyroid tumor. She had no family history of malignant tumor. Computed tomography (CT) and ultrasonography of the neck revealed some masses posterior to both thyroid lobes. Those masses were believed to be parathyroid lesions. However, another mass located posterior to the right upper thyroid lobe seemed to be heterogeneous, which indicated a malignant thyroid tumor as well as parathyroid tumor. The preoperative diagnosis was multiple parathyroid adenoma and suspicious incidental thyroid carcinoma. Therefore, the patient underwent total parathyroidectomy and thyroidectomy. The histopathological diagnosis was parathyroid carcinoma coexisting with multiple parathyroid adenomas. There was no evidence of recurrence at 1 year after the surgery. It was difficult to diagnose PC preoperatively. Few rare cases of PC coexisting with parathyroid adenoma in multiple endocrine neoplasia type 1 (MEN1) have been reported. Therefore, careful follow-up was necessary considering the possibility of MEN1, though she did not wish for a genetic examination.This retrospective study aimed to investigate whether the corono-apical location of sinus tracts differs according to the presence/location of vertical root fracture (VRF) in microsurgically treated root-filled teeth. The cases included were (1) anterior and premolar teeth without a preoperative diagnosis of VRF, (2) those with a periodontal probing depth of ≤3 mm, and (3) those for which preoperative cone-beam computed tomography (CBCT) scans and intraoperative video records were available. VRF was diagnosed intraoperatively. The locations of buccal cortical bone defects and fracture lines were categorized on video images, and the corono-apical sinus tract locations were determined by superimposing video images onto volume-rendered CBCT images. Eleven of the 78 teeth investigated had VRF, and there was no significant difference in the incidence of sinus tracts between vertically fractured and non-fractured teeth (Mann-Whitney U-test, P > 0.05). The location of the sinus tract was significantly more coronal in vertically fractured than in non-fractured teeth (Mann-Whitney U-test, P less then 0.0001). The location of sinus tracts was high correlated with cortical bone defects (Spearman's correlation, P less then 0.0001). In microsurgically treated anterior and premolar teeth with a normal probing depth, sinus tracts were located more coronally in vertically fractured than in non-fractured teeth, and were highly correlated with the location of cortical bone defects.The aim of this study is to determine the cytotoxic effects of tetrasodium ethylenediaminetetraacetic acid (EDTANa4) when used alone or when combined with sodium hypochlorite (NaOCl), with and without the addition of cetrimide (CTR). Human pulmonary fibroblast cell line was exposed to the following irrigating solutions group 1, 2.5% NaOCl; group 2, 10% EDTANa4; group 3, 20% EDTANa4; group 4, 2.5% NaOCl/5% EDTANa4; group 5, 2.5% NaOCl/10% EDTANa4; group 6, 2.5% NaOCl/5% EDTANa4/0.2% CTR; group 7, 2.5% NaOCl/10% EDTANa4/0.2% CTR; group 8, control, cells in Dulbecco's modified Eagle's medium. Methyl thiazol tetrazolium assay was used to determine the viability of cells after 1 and 24 h. Viability percentages were analyzed for global comparison using the Welch test followed by the Games-Howell test to determine groups with similar viability, and the Student's t test was used to compare the two times. The lowest viability was obtained with a 2.5% NaOCl solution at both time periods. The association of NaOCl with EDTANa4 increased the cellular viability in direct relation with the concentration of the chelating agent.
