Objective: To determine the frequency of adverse reactions to chemotherapeutic drugs in children with ALL. Material and Methods: Intensive pharmacovigilance was used to record the reports of adverse reactions to vincristine, L-asparaginase and the vincristine-L-asparaginase combination in children with ALL in a paediatric hospital. For each notification, the adverse reactions were analyzed in order to verify causality. Results: Forty patients were evaluated. Twenty children were female (50.0%) and 20 were male (50%). The children had a mean age, weight and height (±standard deviation: SD) of 8.1 (±3.4) years, 31.4 (±13.9) kg and 1.3 (±0.2) m, respectively. Vincristine was administered to 19 patients, vincristine plus L-asparaginase were given to 19 patients and only 2 patients used L-asparaginase. One-hundred-ninety adverse reactions were detected in the patients, with an average (±SD) of 4.8 (±2.6). Ondansetron was the drug administered for the treating of nausea and vomiting. One hundred eighty-one (95.3%) adverse reactions were identified as “definite”, 5 (2.6%) as “probable” and 4 (2.1%) as “doubtful”. Conclusions: There is a high incidence of adverse reactions by the administration of vincristine and L-asparaginase;the reactions of highest incidence were: nausea, vomiting, neutropenia, diarrhea, constipation, mucositis, headache, and abdominal pain. It is important to promote the detection, collection, reporting, assessment and treatment of ARD’s in children. It is necessary to promote the conduct further studies on pharmacovigilance with this type of treatments and to increase the duration of the studies.展开更多

The best bacteria were selected using growth kinetics and statistical analysis with the Sigma Plot 11 program. Physical-chemical tests pH, % acidity of the dough. Physical tests, texture profile analysis, image analysis of the crumb structure and sensory analysis were performed on the finished product. The results show that the most suitable LAB to ferment dough in 5 hours is Lactobacillus paracasei ssp. paracasei which reduce pH and increase acidity more quickly. The combination of Lactobacillus paracasei ssp. paracasei plus baker’s yeast presents better quality attributes in terms of texture, flavor and appearance for the final consumer.展开更多
