Association between bisphosphonates and jaw osteonecrosis: a study in Wistar rats

This work aimed at determining whether bisphosphonate therapy produces a sufficient condition for jaw osteonecrosis after tooth extraction.

Identificação das dúvidas e dificuldades de gestantes e puérperas em relação ao aleitamento materno

Purposes this research aimed to identify and describe the doubts and difficulties of pregnant and postpartum women about breastfeeding, and compare them on the pregnancy period and postpartum period. Methods it is characterized by a cross-sectional, descriptive, comparative, composed of two groups: pregnant and postpartum women. There was the approval of the Ethics Committee in Research / Santa Casa under no 23355. For collect it drafted a questionnaire with questions about breastfeeding. The variables were analyzed by associations between the answers of the groups using the Chi-square test, Fisher’s exact and Student’s t. Results the postpartum women had higher knowledge scores about breastfeeding compared to pregnant women (p = 0,001). By linking the age with the knowledge, the higher the postpartum women age the higher their percentage of knowledge (r = 0, 283, p = 0,011). By analyzing the primiparous mothers, we found that these were more complaints compared to those who already have one or more children (p = 0,014). Conclusions pregnant women, primiparous women and teenager girls have more doubts and difficulties in relation to breastfeeding. The care team must be prepared for the pregnant woman has the right to treat her breast awareness and breast feeding, reaching the puerperal period safer and encouraged for exclusive breastfeeding.

Cephalometric skeletal evaluation of patients with Incontinentia Pigmenti

PURPOSE The aim of this study was to evaluate the skeletal characteristics of patients with the rare genetic disease of Incontinentia Pigmenti, by lateral cephalometric analysis on the antero-posterior plane and by frontal cephalometric analysis on the horizontal plane. METHODS Lateral skeletal cephalometric analyses were performed according to Steiner for evaluation of antero-posterior direction, and frontal skeletal cephalometric analyses according to Ricketts for evaluation of horizontal direction in 9 patients with IP. Left and right facial widths at the level of the zygomatic arch were also evaluated. The Student t-test was used for paired to a 5% level of significance data. RESULTS The lateral skeletal cephalometric findings were not statistically significant, but the Class II was the most frequent finding (44.4%), followed by Class III (33.3%) and Class I (22.2%). The right maxillo-mandibular width was significantly lower than normal values, and the right facial width was significantly higher than the left, at the level of the zygomatic arch. CONCLUSIONS Patients with IP showed more skeletal discrepancies of Class II and III than Class I malocclusion, and had significant horizontal facial skeletal asymmetries. This should alert health professionals to route these patients for orthodontic assessment and possible therapeutic interventions. However, larger samples are needed to better elucidate if these cephalometric findings can be specifically related to IP.

Tobacco Influence on Taste and Smell: Systematic Review of the Literature

Introduction  In Brazil, estimates show that 14.7% of the adult population smokes, and changes in smell and taste arising from tobacco consumption are largely present in this population, which is an aggravating factor to these dysfunctions. Objectives  The objective of this study is to systematically review the findings in the literature about the influence of smoking on smell and taste. Data Synthesis  Our research covered articles published from January 1980 to August 2014 in the following databases: MEDLINE (accessed through PubMed), LILACS, Cochrane Library, and SciELO. We conducted separate lines of research: one concerning smell and the other, taste. We analyzed all the articles that presented randomized controlled studies involving the relation between smoking and smell and taste. Articles that presented unclear methodologies and those whose main results did not target the smell or taste of the subjects were excluded. Titles and abstracts of the articles identified by the research strategy were evaluated by researchers. We included four studies, two of which were exclusively about smell: the first noted the relation between the perception of puff strength and nicotine content; the second did not find any differences in the thresholds and discriminative capacity between smokers and nonsmokers. One article considered only taste and supports the relation between smoking and flavor, another considered both sensory modalities and observes positive results toward the relation immediately after smoking cessation. Conclusion  Three of the four studies presented positive results for the researched variables.

Alterações estomatognáticas e de fala são comuns entre crianças com incontinência pigmentar

Purpose: To identify possible speech-language disorders in children with Incontinentia Pigmenti (IP), seeking to characterize the role of speech therapy in the evaluation and management of this genetic condition. Methods: The sample was composed of seven female children diagnosed with IP. Results: The patients in the sample had a mean age of 6.4 years. Among the main structural features verified in the patients, highlighted the presence of no physiological diastema and hard palate abnormalities, found both in 85.7 % of the sample, in addition to tooth agenesis in 71.4% of cases. As for functional findings, 71.4 % of the sample had abnormal tongue mobility and 57.1%, inappropriate chewing. As for changes in speech, the main findings consisted of phonetic/phonological alterations, verified in 85.7 % of the sample, being the most common phonetic alteration characterized by distortion of alveolar fricative [s], present in 57.1 % of cases. None of the children had abnormal voice and swallowing according to the used protocol. Furthermore, no detectable hearing abnormality was observed according to claim of the family or by observation during the evaluation. Conclusion: In this sample the most frequent speech-language alterations verified among the patients with IP were mainly related to the stomatognathic system structures and speech.
