Abstract: this study aimed at investigating the ways to prevent burns identified by burned patients and their relatives. data were collected at the burns unit of the ribeir?o preto medical school clinical hospital, university of s?o paulo - brazil by means of interviews with burned patients and their relatives. four referees categorized data. in order to verify the existence of agreement among the referees with regard to categorization, the non-parametric correlation measure was used - contingency coefficient. fifty-seven people were interviewed: 24 relatives and 33 burned patients. of the 33 interviewed patients, 18 had suffered accidents at home. of the 57 interviewees, 11 stated that they could not have avoided the accident causing the burn. twenty patients and 12 relatives identified risk situations at home or at work and 13 patients and 12 relatives did not identify any types of risk situations. the relatives and patients referred to the following preventive measures for burning accidents: to be attentive to the activities that they perform and to be more careful while handling flammable products.
How auditory temporal processing deficits relate to dyslexia
Murphy, C.F.B.;Schochat, E.;
Brazilian Journal of Medical and Biological Research , 2009, DOI: 10.1590/S0100-879X2009000700009
Abstract: studies have shown that dyslexic children present a deficiency in the temporal processing of auditory stimuli applied in rapid succession. however, discussion continues concerning the way this deficiency can be influenced by temporal variables of auditory processing tests. therefore, the purpose of the present study was to analyze by auditory temporal processing tests the effect of temporal variables such as interstimulus intervals, stimulus duration and type of task on dyslexic children compared to a control group. of the 60 children evaluated, 33 were dyslexic (mean age = 10.5 years) and 27 were normal controls (mean age = 10.8 years). auditory processing tests assess the abilities of discrimination and ordering of stimuli in relation to their duration and frequency. results showed a significant difference in the average accuracy of control and dyslexic groups considering each variable (interstimulus intervals: 47.9 ± 5.5 vs 37.18 ± 6.0; stimulus duration: 61.4 ± 7.6 vs 50.9 ± 9.0; type of task: 59.9 ± 7.9 vs 46.5 ± 9.0) and the dyslexic group demonstrated significantly lower performance in all situations. moreover, there was an interactive effect between the group and the duration of stimulus variables for the frequency-pattern tests, with the dyslexic group demonstrating significantly lower results for short durations (53.4 ± 8.2 vs 48.4 ± 11.1), as opposed to no difference in performance for the control group (62.2 ± 7.1 vs 60.6 ± 7.9). these results support the hypothesis that associates dyslexia with auditory temporal processing, identifying the stimulus-duration variable as the only one that unequally influenced the performance of the two groups.
Generalization of temporal order detection skill learning: two experimental studies of children with dyslexia
Murphy, C.F.B.;Schochat, E.;
Brazilian Journal of Medical and Biological Research , 2010, DOI: 10.1590/S0100-879X2010007500016
Abstract: the objective of this study was to investigate the phenomenon of learning generalization of a specific skill of auditory temporal processing (temporal order detection) in children with dyslexia. the frequency order discrimination task was applied to children with dyslexia and its effect after training was analyzed in the same trained task and in a different task (duration order discrimination) involving the temporal order discrimination too. during study 1, one group of subjects with dyslexia (n = 12; mean age = 10.9 ± 1.4 years) was trained and compared to a group of untrained dyslexic children (n = 28; mean age = 10.4 ± 2.1 years). in study 2, the performance of a trained dyslexic group (n = 18; mean age = 10.1 ± 2.1 years) was compared at three different times: 2 months before training, at the beginning of training, and at the end of training. training was carried out for 2 months using a computer program responsible for training frequency ordering skill. in study 1, the trained group showed significant improvement after training only for frequency ordering task compared to the untrained group (p < 0.001). in study 2, the children showed improvement in the last interval in both frequency ordering (p < 0.001) and duration ordering (p = 0.01) tasks. these results showed differences regarding the presence of learning generalization of temporal order detection, since there was generalization of learning in only one of the studies. the presence of methodological differences between the studies, as well as the relationship between trained task and evaluated tasks, are discussed.

Abstract: objective: estimates of vaccination costs usually provide only point estimates at national level with no information on cost variation. in practice, however, such information is necessary for programme managers. this paper presents information on the variations in costs of delivering routine immunization services in three diverse districts of peru: ayacucho (a mountainous area), san martin (a jungle area) and lima (a coastal area). methods: we consider the impact of variability on predictions of cost and reflect on the likely impact on expected cost-effectiveness ratios, policy decisions and future research practice. all costs are in 2002 prices in us$ and include the costs of providing vaccination services incurred by 19 government health facilities during the january-december 2002 financial year. vaccine wastage rates have been estimated using stock records. findings: the cost per fully vaccinated child ranged from us$ 16.63-24.52 in ayacucho, us$ 21.79-36.69 in san martin and us$ 9.58-20.31 in lima. the volume of vaccines administered and wastage rates are determinants of the variation in costs of delivering routine immunization services. conclusion: this study shows there is considerable variation in the costs of providing vaccines across geographical regions and different types of facilities. information on how costs vary can be used as a basis from which to generalize to other settings and provide more accurate estimates for decision-makers who do not have disaggregated data on local costs. future studies should include sufficiently large sample sizes and ensure that regions are carefully selected in order to maximize the interpretation of cost variation.

Abstract: mentha x villosa huds (labiatae) is an aromatic herb widely used in folk medicine. since the essential oil of the herb has many pharmacological activities, including antispasmodic effects, we determined whether the oil and its major constituent, piperitenone oxide (po), have antinociceptive activity. the essential oil of m. x villosa (eomv) and po administered orally at 200 mg/kg (vehicle: 0.1% tween 80 in water) significantly reduced the writhings induced by acetic acid from control values of 59.5 ± 3.1 s (n = 10) to 31.9 ± 2.8 s (n = 10) and 23.8 ± 3.4 s (n = 10), respectively. when administered at 100 and 200 mg/kg, eomv reduced the paw licking time for the second phase of the formalin test from the control value of 20.6 ± 2.1 s (n = 13) to 5.3 ± 2.2 s (n = 12) and 2.7 ± 1.2 s (n = 18), respectively. at 100 and 200 mg/kg, po reduced this second phase to 8.3 ± 2.7 s (n = 12) and 3.0 ± 1.2 s (n = 10), respectively. this effect of eomv and po was not reversed by naloxone. eomv and po had no significant effect on the first phase of the formalin test. as evaluated by the hot-plate and tail immersion test, eomv and po, at doses up to 200 mg/kg, showed no analgesic activity. these results show that eomv and po have antinociceptive activity and suggest that this effect is probably an indirect anti-inflammatory effect, which does not involve the central nervous system.
