Abstract:

Difficult intubation, inadequate ventilation and esophageal intubation are the principal causes of death or brain damage related to airway manipulation. The objective of this cross-sectional study was to correlate a preanesthetic evaluation that may be capable of predicting a difficult intubation with the conditions encountered at laryngoscopy and endotracheal intubation. Eighty-one patients submitted to general anesthesia were evaluated at a preanesthetic consultation according to the modified Mallampati classification, the Wilson score and the American Society of Anesthesiologists (ASA) difficult airway algorithm. Findings were then correlated with the Cormack-Lehane classification and with the number of attempts at endotracheal intubation. No statistically significant correlations were found between the patients’ Mallampati classification and their Cormack-Lehane grade or between the Mallampati classification and the number of attempts required to achieve endotracheal intubation. Laryngoscopy proved difficult in four patients and in all of these cases the Wilson score had been indicative of a possibly difficult airway, highlighting its good predicting sensitivity. However, the specificity of this test was low, since another 24 patients had the same Wilson score but were classified as Cormack-Lehane I/II. Moreover, two patients who had a Wilson score ≥ 4 were also classified as Cormack-Lehane grade I/II. The study concluded that the Wilson score, although seldom used in clinical practice, is a highly sensitive predictor of a difficult airway; its specificity, however, is low.

Jornal Brasileiro de Patologia e Medicina Laboratorial , 2002, DOI: 10.1590/S1676-24442002000400012
Abstract: the rate and morphology of collagen degradation were comparatively analyzed in rats with "early" and "late" carbon tetrachloride-induced hepatic fibrosis, during three different periods after discontinuation of the drug. treatment with ccl4 lasted for eight weeks for the group of early fibrosis and 12 weeks for the late fibrosis group. fibrosis gradually disappeared, but when quantitative methods were applied, the amount of collagen degradation and removal in early and late fibrosis did not reach statistical significance. the light microscope and ultrastructural changes were also qualitatively similar in both cases. probably some long-lasting effects to the liver, induced by the drug, prevented early hepatic fibrosis from undergoing the characteristic ultrastructural changes seen during "acute" collagen degradation, as compared to other experimental models of hepatic fibrosis, after the causal agent is totally removed. present findings suggest that not only the age of fibrosis but also the overall damage inflicted to the organ are limiting factors in the process of collagen degradation and removal.

Bezerra, Andrea Carla Caldas;Costa, Antonia Aurelice Aurélio;Cavalcanti, Laise de Holanda;
Acta Botanica Brasilica , 2011, DOI: 10.1590/S0102-33062011000100003
Abstract: cecropia adenopus (ambay pumpwood) is a frequent native species on the edges of woods and clearings and is considered a pioneer species in re-colonized areas. despite its distribution from mexico to argentina, this substrate has never been examined in detail regarding the presence of myxomycetes. in the present study, the myxobiota associated with leaf debris of c. adenopus was investigated in two atlantic rainforest conservation units located in the brazilian state of rio grande do norte. five specimens and one plasmodium were obtained directly from the field and 87 were developed in 43.7% of 200 moist-chamber cultures set up separately with blades and petioles. fifteen species were identified and illustrated. the two predominant groups were representatives of trichiales and physarales. didymium columella-cavum was recorded for the second time in brazil and in the world.

Journal of Applied Oral Science , 2004, DOI: 10.1590/S1678-77572004000300011
Abstract: the purpose of the present study was to evaluate the microleakage at the composite-repair interface using different bonding systems. composite resin specimens (filtek z250 - 3m-espe) were divided into five groups (n=20) according to the following bonding mechanism: c - control - etching with 35% phosphoric acid; sb1 - etching and application of one coat of single bond (3m-espe); sb2 - etching and application of two coats of single bond (3m-espe); smp1 - etching, application of scotchbond multi-purpose primer (3m-espe) followed by the adhesive and, smp2 - etching, application of scotchbond multi-purpose adhesive (3m-espe) without the primer. thereafter, all groups received new resin application. samples were thermocycled (500 cycles / 5oc - 55oc [±2]) and immersed for 4h in 2% methylene blue buffered dye solution (7.0 ph). three examiners measured the extent of microleakage in a stereoscope microscope, using four representative scores. for all experimental groups, no significant difference in microleakage at the repair was identified by kruskal-wallis test (p > 0.05). therefore, different types of bonding systems presented the same effect on the dye penetration along the repair interface.
Statistical results on restorative dentistry experiments: effect of the interaction between main variables

Journal of Applied Oral Science , 2010, DOI: 10.1590/S1678-77572010000300010
Abstract: statistical analysis interpretation is a critical field in scientifc research. when there is more than one main variable being studied in a research, the effect of the interaction between those variables is fundamental on experiments discussion. however, some doubts can occur when the p-value of the interaction is greater than the signifcance level. objective: to determine the most adequate interpretation for factorial experiments with p-values of the interaction nearly higher than the signifcance level. materials and methods: the p-values of the interactions found in two restorative dentistry experiments (0.053 and 0.068) were interpreted in two distinct ways: considering the interaction as not signifcant and as signifcant. results: different findings were observed between the two analyses, and studies results became more coherent when the signifcant interaction was used. conclusion: the p-value of the interaction between main variables must be analyzed with caution because it can change the outcomes of research studies. researchers are strongly advised to interpret carefully the results of their statistical analysis in order to discuss the findings of their experiments properly.

Journal of Applied Oral Science , 2013,
Abstract: Background: Photodynamic therapy (PDT) is a method of microbial reduction which can benefit periodontal treatment in areas of difficult access, such as deep pockets and furcations. The aim of this randomized controlled clinical trial was to evaluate the effects of PDT as an adjunct to full-mouth ultrasonic debridement in the treatment of severe chronic periodontitis. Material and Methods: Twenty-two patients with at least one pocket with a probing depth (PD) of ≥7 mm and one pocket with a PD of ≥5 mm and bleeding on probing (BOP) on each side of the mouth were included, characterizing a split mouth design. The control group underwent full-mouth ultrasonic debridement and the test group received the same treatment associated with PDT. The PDT was performed on only one side of the mouth and the initial step consisted of subgingival irrigation with 0.005% methylene blue dye. Two minutes after applying the photosensitizer, the low power laser – AsGaAl (Photon Lase III – PL7336, DMC, S o Carlos -S o Paulo, Brazil) was applied (660 nm, 100 mW, 9 J, 90 seconds per site, 320 J/cm 2 , diameter tip 600 μm). The following clinical parameters were evaluated: plaque index, gingival index, BOP, gingival recession (GR), PD, and clinical attachment level (CAL). All parameters were collected before, 1, 3 and 6 months after treatment. Results: An improvement in BOP, PD and CAL was observed after treatment, in both groups, but without any difference between them. After 6 months, the PD decreased from 5.11±0.56 mm to 2.83±0.47 mm in the test group (p<0.05) and from 5.15±0.46 mm to 2.83±0.40 mm in the control group (p<0.05). The CAL changed, after 6 months, from 5.49±0.76 mm to 3.41±0.84 mm in the test group (p<0.05) and from 5.53±0.54 to 3.39±0.51 mm in the control group (p<0.05). Conclusion: Both approaches resulted in significant clinical improvements in the treatment of severe chronic periodontits, however, the PDT did not provide any additional benefit to those obtained with full-mouth ultrasonic debridement used alone.

Health (Health) , 2015, DOI: 10.4236/health.2015.714199
Abstract: Objective: The study aims to evaluate the use of a teaching method proposed by Paulo Freire, Culture Circles, in the education of teenagers multipliers on leprosy awareness. Methods: It is an action-research study with a qualitative approach developed in a public school in Pernambuco, Brazil. Five Culture Circles were conducted involving the participation of 26 teenagers. The followings were used as data collection tools: observation, field notes, photography and filming. Results: The educational intervention on health addressed the following topics: 1) Definition and transmission of leprosy; 2) Characteristics and diagnosis of leprosy; 3) Treatment of leprosy; 4) Aesthetics, prejudice and mental health related to leprosy; and 5) Planning of educational activities for teenagers as health multipliers on leprosy awareness. The educational action on health provided this age group to perceive themselves, act as political subjects in the development of Culture Circles, and act as protagonists in the dissemination of knowledge on leprosy. Conclusions: This study highlights that the application of active methodologies, such as Culture Circles, is able to encourage the engagement of young people in community empowerment and bring together health professionals and the school community in an intersectoral work in order to develop action strategies involving the promotion of health in the context of neglected diseases such as leprosy.
