RESUMO
ABSTRACT Objective: To discuss cerebral sinovenous thrombosis (CSVT), an important mortality and morbidity factor, developing in the progression of ulcerative colitis (UC) in childhood age, in the light of the literature. Methods: A search of PubMed and Google Scholar database was conducted on April 2014. This study retrospectively investigates the cases diagnosed with UC with complication of CSVT below 18 years of age between years 1971 and 2014. The cases were analysed with respect to age, gender, disease duration and treatment, potential risk factors, clinical findings, location of thrombosis, thrombolytic therapeutical applications, and clinical progressions. Results: Twenty-four paediatric patients aged 5 and 18 years were included in the study. Cerebral sinovenous thrombosis had developed during active disease period in 23 (95.8%) patients. The most common complaints were headache (79.1%) and emesis (29.1%). The most frequently detected risk factors for CSVT were anaemia (58.3%) and thrombocytosis (45.8%). Inherited thrombotic disorders were encountered in 10 (41.6%) of the cases. The most common location sites for CSVT were the transverse (33.3%) and the sigmoid (33.3%) sinuses. It had been discovered that 19 (79.2%) of the cases were healed completely without a sequelae, whereas neurological sequelae remained in three (12.5%) of the cases and two (8.3%) of the cases died. Conclusion: In the presence of a prior diagnosis of UC and emergency presentation with emesis, headache, mood changes and particularly seizure, the presence of CSVT should certainly be considered.
RESUMO
New therapeutic approaches are still needed for effective malignant pleural mesothelioma treatment. The use of classical chemotherapy agents in combination with newly developed molecules may shed light on new therapeutic approaches. We aimed to determine the efficacy of panobinostat, alone and in combination with cisplatin, on cell survival and mRNA expression of FOXO3A, CCND1, and CASP9 genes in both mesothelioma and healthy mesothelial cell lines. Cells were treated with 1-100 µM cisplatin and 25-1000 nM panobinostat. Methylthiazol tetrazolium assays were performed to determine cell viability. mRNA expression levels of genes were analyzed with quantitative real-time polymerase chain reaction. Cisplatin and panobinostat exposure of the cells for 24 h resulted in decreased cell survival. The combined treatment was found to be more effective. No significant changes were observed with respect to CCND1 expression after exposure to agents alone or in combination. However, agents in combination resulted in upregulation of FOXO3A and CASP9 in MSTO-211H cells. Gene expression levels were not affected by any agents in healthy cells. Use of cisplatin in combination with new chemotherapeutic agents may reduce the toxic effects of cisplatin in normal cells and result in more effective removal of tumor cells.
