| 1 | Common dental diseases in children and malocclusion显示文摘Malocclusion is a worldwide dental problem that influences the affected individuals to varying degrees. Many factors contribute to the anomaly in dentition, including hereditary and environmental aspects. Dental caries, pulpal and periapical lesions, dental trauma, abnormality of development, and oral habits are most common dental diseases in children that strongly relate to malocclusion. Management of oral health in the early childhood stage is carried out in clinic work of pediatric dentistry to minimize the unwanted effect of these diseases on dentition. This article highlights these diseases and their impacts on malocclusion in sequence. Prevention, treatment, and management of these conditions are also illustrated in order to achieve successful oral health for children and adolescents, even for their adult stage. | Jing Zou Mingmei Meng Clarice S Law Yale Rao Xuedong Zhou | 2018 | International Journal of Oral Science2018，10，2： | 16 |
| 3 | Epidemiology, resistant pathogens, and causes of early death in cases of bloodstream infection in patients with hematological malignancies from 2012-2019显示文摘Purpose:To investigate the epidemiology,causative pathogen antibiotic susceptibility,and mortality risk factors of bloodstream infection(BSI)in patients with hematological malignancies(HMs).Methods:Single-center retrospective analysis of BSI cases in patients with HMs in a Chinese tertiary hospital from 2012-2019.Results:Among 17,796 analyzed admissions,508 BSI episodes(2.9%;95%confidence interval:2.6%-3.2%)were identified.Of 522 resulting isolates,326(62.5%)were Gram-negative,173(33.1%)were Gram-positive.The BSI incidence among patients with different HMs(severe aplastic anemia:6.7%;acute leukemia:6.2%;myelodysplastic syndrome:3.2%;multiple myeloma:1.3%;and lymphoma:1.0%)differed significantly(p<0.001).The BSI incidence was significantly higher in the hematopoietic stem cell transplantation(HSCT)group(10.2%)than in the non-HSCT group(2.5%;p<0.001).Escherichia coli(30.7%,160/522)was the most common pathogen,followed by Coagulase-negative staphylococci(19.4%,101/522)and Klebsiella pneumoniae(10.0%,52/522).,The rates of imipenem resistance for E.coli,K.pneumoniae,Pseudomonas aeruginosa,and Acinetobacter baumannii were 6.4%,15.0%,27.8%,and 79.0%,respectively.All the Gram-positive pathogens were linezolid susceptible.Three vancomycin-resistant Enterococcus species were isolated.The overall 14-day mortality was 9.8%(95%confidence interval:7.2%-12.4%).A multivariate analysis showed that HM subtype severe aplastic anemia,A.baumannii,and malignancy non-remission were independent 14-day mortality risk factors.Conclusions:Gram-negative bacteria were the most common pathogens,with E.coli as the predominant strain,causing BSIs in HM patients.A carbapenem-resistant A.baumanni with a high mortality rate in HM patients made empirical antimicrobial choice a highly challenging issue. | Meng Li Mingmei Du Honghua Li Daihong Liu Yunxi Liu | 2022 | Infectious Medicine2022，1，1： | 0 |
