[Analysis of factors affecting soft tissue infection after oral and maxillofacial debridement].

PURPOSE: To explore the factors affecting soft tissue infection after oral and maxillofacial debridement. METHODS: Fifty hundred patients with debridement were enrolled in this study from January 2013 to June 2016. The patients were divided into 2 groups according to soft tissue infection, 18 cases in infection group and 482 cases in non-infection group. Age, mean time to surgery, average length of stay, duration of antibiotics use, abbreviated injury scale (AIS), combined injuries, maxillofacial fractures, soft tissue injury, type of fracture, and history of diabetes were recorded and analyzed using SPSS 19.0 software package. RESULTS: The factors influencing soft tissue infection after oral and maxillofacial surgery were the aged, longer hospital stay, longer operation time, longer antibiotics use time, higher AIS score, Jaw bone injury and diabetes. CONCLUSIONS: The factors influencing soft tissue infection after oral and maxillofacial debridement are various. The aged, longer operation time, higher AIS score, jaw bone involvement lip and chin injury as well as diabetes might be the independent factors. Health care providers should give preventive measures to reduce the incidence of infection, according to specific factors.

Vitamin D receptor rs2228570 polymorphism and susceptibly to ovarian cancer: a meta-analysis.

The role of vitamin D receptor (VDR) rs2228570 polymorphism on the risk of ovarian cancer has been studied in many studies, but the relationship between VDR rs2228570 polymorphism and ovarian cancer is still unclear. We thus performed a meta-analysis of published studies to provide a comprehensive assessment of the association. Fourteen individual studies with a total of 10,964 subjects were finally included into the meta-analysis. We assessed the association by calculating the pooled odds ratio (OR) with 95 % confidence intervals (95 % CI). There was no heterogeneity among those included studies. Meta-analysis of 14 studies showed that the VDR rs2228570 polymorphism was associated with risk of ovarian cancer under three main comparison models (T versus C: OR = 1.09, 95 % CI 1.03 to 1.15, P = 0.004; TT versus CC: OR = 1.17, 95 % CI 1.04 to 1.32, P = 0.01; and TT/CT versus CC: OR = 1.12, 95 % CI 1.03 to 1.21, P = 0.007). Subgroup analysis in Caucasians further identified the obvious association. There was no evidence of publications bias. These data from the meta-analysis suggest that VDR rs2228570 polymorphism is associated with risk of ovarian cancer in Caucasians. More studies are warranted to assess the association between the VDR rs2228570 polymorphism and ovarian cancer in Asians and Africans.

Multi-centric solid-pseudopapillary neoplasm of the pancreas.

Multi-centric solid-pseudopapillary neoplasm (SPN) of the pancreas is a rare tumor: only 4 cases are reported in the literature. The clinical and pathological features have not yet been fully clarified. We report 3 cases of multi-centric SPN and discuss their clinical presentations and histological and immunohistochemical features, comparing with solitary SPN. Among the total of 7 cases, 6 were female and 1 was male. Patients had nonspecific symptoms at presentation. Tumors were often large and well demarcated with cystic degeneration and clear margin between lumps. Histologically, characteristic pseudopapilla was formed with uniform cells surrounding the delicate blood vessels. Tumor cells were positive for vimentin, synaptophysin, progesterone receptor, and CD10 and demonstrated nuclear localization of ß-catenin. The prognosis of patients was excellent after complete surgical resections. Multi-centric SPN shares similar clinical and pathological features to solitary SPN.
