Observational Study
Invasive candidiasis: Risk factor for mortality in a pediatric tertiary care hospital in south of Brazil.
Invasive candidiasis (IC) is a major cause of morbimortality in children. Previous studies described the clinical characteristics and risk factors for this infection; however, limited data are available on the predictors of mortality in these patients. In this context, we evaluated the risk factors associated with death due to IC in a pediatric tertiary care hospital in South of Brazil. ⋯ Data from this study suggest that biofilm formation by Candida sp. is associated with increased mortality, and this is the first study to correlate the male sex and cardiological disease as risk factors for death in pediatric IC patients.

Case Reports
Peri-cardiac surgery coagulation management in a severe hemophilia A patient: A case report.
Hemophilia A (HA) is an X-linked recessive disorder caused by clotting factor VIII (FVIII) deficiency. There is limited data on the use of replacement therapy in cardiac surgery. Since no international guideline for anticoagulation in such patient exists, careful thought should be taken to design an individualized anticoagulation strategy. ⋯ The anticoagulant or antiplatelet regimen of HA patient following surgery should be individualized based on the evaluation of the risk factors for bleeding and thrombosis and the lowest FVIII activity ever recorded after FVIII replacement therapy.

Re-irradiation after radiotherapy is a common treatment for locally recurrent esophageal cancer. However, the side effects of re-irradiation are serious. The most serious adverse reactions of re-irradiation include esophageal perforation and hemorrhage caused by esophageal perforation. Studies have shown that pulsed low-dose rate radiotherapy (PLDR) induces a hypersensitivity effect on tumor tissue and a hyper-repair effect on normal tissue, which can simultaneously reduce damage on the normal tissue and increase the therapeutic effect on the tumor. The objective of this study is to explore whether PLDR can reduce rate of esophageal perforation and improve efficacy in patients with recurrent esophageal squamous cell carcinoma (ESCC) after radiotherapy. ⋯ This study is a prospective, multi-center, open, single-arm clinical trial designed to enroll 27 patients with locally recurrent ESCC after radiotherapy with or without chemotherapy. Re-irradiation will be performed using intensity modulated radiation therapy in 50 Gy/25 fractions. The strategy of PLDR includes dividing 2 Gy into 10 fractions, and administering each irradiating dose of 20 cGy at an interval of 3 minutes before the next low-dose irradiation. The actual dose rate of administration each time will be 16.67 cGy /minute. The primary endpoint in this study is the rate of esophageal perforation. The secondary endpoints are the objective remission rate, the palliative effect on quality of life and pain, and the time of disease progression. The observation time is 2 years after the end of the study.

The cell-surface glycoprotein, mesothelin, is normally present on mesothelial cells. Overexpression of mesothelin has been reported in many tumors and is correlated with poor outcome. We investigated the clinicopathologic significance of mesothelin expression in colorectal adenocarcinoma with microsatellites instability (MSI) status. ⋯ Kaplan-Meier survival curves revealed no significant difference between patients with high mesothelin expression and patients with low mesothelin expression in both recurrence-free survival (RFS) and cancer-specific survival (P = .609 and P = .167, respectively). In subgroup survival analyses, high mesothelin expression was associated with poor RFS in the MSI-High group of colorectal adenocarcinoma (P = .004). High mesothelin expression was significantly associated with aggressive phenotypes and poor patient outcome in MSI-High colorectal adenocarcinoma.

Gastric cancer is still one of the most common cancer in East Asia. More than 70% gastric cancer patients are diagnosed at an advanced stage in China. Moreover, about 10% cases are unresectable which usually suffer a poor prognosis with a median survival time of 5 to 12 months. In recent years, some clinical studies found that many unresectable gastric cancer cases could get opportunity for surgery after treatment that improve prognosis significantly PATIENT CONCERNS:: 64-year-old male patient was admitted with upper abdominal pain. Upper gastrointestinal endoscopy showed a large ulcerated tumor located from the cardia to the anterior wall of the upper gastric body. Histopathological examination showed it was moderately differentiated adenocarcinoma. Computed tomography (CT) scan image showed a large bulging mass with internal ulcer at the lesser curvature wall, left gastric artery and coeliac trunk were surrounded by fused lymph nodes. ⋯ In this case, oral chemotherapy combined with TACE which was rarely reported in the treatment of unresectable gastric cancer achieves a great therapeutic benefit. Although further clinical studies will be needed to establish, it may be a potent strategy for degrading stage and supplying a new chance for surgery.
