Staphylococcus spp. Na cavidade bucal e na bolsa periodontal de indivíduos com periodontite crônica: presença e sensibilidade aos antibióticos

Staphylococcus are not usually studied in the oral cavity, when this happens, they are considered to belong to transitory microflora. Individuals that present periodontal disease represent possibles reservoirs of these opportunist bacteria in the oral cavity. The use of antibiotics whether for treatment of periodontal disease or due to hospital infections, may predispose the increase of the Staphylococcus spp. in the oral cavity because they easily become resistant to antibiotics, resulting in superinfection. The study was made with 88 patients, minimum age- 25 years old, presenting chronical periodontitis, with, at least, two sites having a probing pocket bigger or equal to 5mm. After anamnese and clinical periodontal examination samples were taken from the periodontal pocket using paper cones and from the oral cavity using mouth rinse. Of the total patients 37,50% presented Staphylococcus spp. in the periodontal pocket and 61,36% in lhe oral cavity; 27,27% presented bacteria in the two sites, not necessarily of the same specie. S. epidermidis was the most prevailing specie in periodontal pocket (15,9%) and oral cavity (27,27%). Positive for S. aureus in the periodontal pocket were 4,5% and for the oral cavity 25%, and 3,4% were positive for the two sites. There was not found significative statistical difference referring to the presence of the microorganisms as to age, smoking habit and increase of the probing depth. The majority of the isolated Staphylococcus samples showed resistance to the tested antibiotics, indicating that the drugs as an adjunct to periodontal therapy, must be seen with caution

Long-term skeletal and dental effects and treatment timing for functional appliances in Class II malocclusion

Objective: To analyze the long-term skeletal and dentoalveolar effects and to evaluate treatment timing of Class II treatment with functional appliances followed by fixed appliances.Materials and Methods: A group of 40 patients (22 females and 18 males) with Class II malocclusion consecutively treated either with a Bionator or an Activator followed by fixed appliances was compared with a control group of 20 subjects (9 females and 11 males) with untreated Class II malocclusion. Lateral cephalograms were available at the start of treatment (mean age 10 years), end of treatment with functional appliances (mean age 12 years), and long-term observation (mean age 18.6 years). The treated sample also was divided into two groups according to skeletal maturity. The early-treatment group was composed of 20 subjects (12 females and 8 males) treated before puberty, while the late-treatment group included 20 subjects (10 females and 10 males) treated at puberty. Statistical comparisons were performed with analysis of variance followed by Tukey's post hoc tests.Results: Significant long-term mandibular changes (Co-Gn) in the treated group (3.6 mm over the controls) were associated with improvements in the skeletal sagittal intermaxillary relationship, overjet, and molar relationship (similar to 3.0-3.5 mm). Treatment during the pubertal peak was able to produce significantly greater increases in total mandibular length (4.3 mm) and mandibular ramus height (3.1 mm) associated with a significant advancement of the bony chin (3.9 mm) when compared with treatment before puberty.Conclusion: Treatment of Class II malocclusion with functional appliances appears to be more effective at puberty.

Keratosis pilaris and prevalence of acne vulgaris: a cross-sectional study

BACKGROUND: Acne vulgaris has an important genetic predisposition, as well as keratosis pilaris. Clinical observations suggest that patients with keratosis pilaris have less frequent or less severe acne breakouts; however, we found no studies on this regard OBJECTIVE: To determine if the presence of keratosis pilaris is associated with lower prevalence and severity of acne. METHODS: A cross-sectional study was conducted with dermatology outpatients aged between 14 and 35 years. We evaluated history and clinical grade of acne, demographic variables, history of atopy, smoking, and use of hormonal contraceptives. Two groups were defined by the presence or absence of moderate to severe keratosis pilaris on the arms and were compared by bivariate analysis and by conditional multiple logistic regression. RESULTS: We included 158 patients (66% women), with a median age of 23 +/- 11 years. Twenty-six percent of them had keratosis pilaris, which was associated with a history of atopy (odds ratio [OR]=2.80 [1.36 to 5.75]; p<0.01). Acne was present in 66% of subjects, and was related to family history of acne (OR=5.75 [2.47 to 13.37]; p<0.01). In bivariate and multivariate analysis, the group with keratosis pilaris had a less frequent history of acne (OR=0.32 [0.14 to 0.70]; p<0.01). CONCLUSION: The presence of moderate to severe keratosis pilaris on the arms was associated with lower prevalence of acne vulgaris and lower severity of facial lesions in adolescents and young adults.

Perceptual and acoustic parameters of vocal nodules in children

Vocal nodules constitute the major cause of dysphonia during childhood. Auditory-perceptual and acoustic vocal analyses have been used to differentiate vocal nodules from normal voice in children.Purpose: To study the value of auditory-perceptual and acoustic vocal analyses in assessments of children with nodules.Design: Diagnostic test study.Patients and interventions: A comparative study was carried out including 100 children with videolaryngoscopic diagnosis of vocal nodules (nodule group-NG); and 100 children without vocal symptoms and with normal videolaryngoscopic exams (control group-CG). The age range of both groups was between 4 and 11 years. All children underwent auditory-perceptual vocal analyses (GRBASI scale); maximum phonation time and s/z ratio were calculated, and acoustic vocal analysis (MDVP software) were carried out.Results: There was no difference in the values of maximum phonation time and s/z ratio between groups. Auditory-perceptual analysis indicated greater compromising of voice parameters for NG, compared to CG: G (79 versus 24), R (53 versus 3), B (67 versus 23) and S (35 versus 1). The values of acoustic parameters jitter, PPQ shimmer, APQ, NHR and SPI were higher for NG for CG. The parameter f0 did not differ between groups.Conclusion: Compromising of auditory-perceptual (G, R, B and S) and acoustic vocal parameters (jitter, PPQ shimmer, APQ, NHR and SPI) was greater for children with nodules than for those of the control group, which makes them important methods for assessing child dysphonia.

Efeitos dentoesqueléticos do tratamento da classe II utilizando o aparelho de Herbst associados à mecânica Straight-wire

This study compared the effect of the treatment protocol for correcting Class Il malocclusion using the Herbst appliance followed by full fixed Straigh-wire mechanics, in two populations, one Brazilian and one of North American origin As a untreated control sample the data from the University of Michigan Elementary and Secondary School Growth Study (UMGS) was used. Our sample was composed of 12 males and 12 females, with initial mean age of 12 years 7 months and final mean ages of 15 years and 3 months. The Michigan patients comprised 21 females and 7 males, with an initial mean age of 11 years and 9 months and final mean age of 14 years and 4 months. The control sample was paired in number, sex and age to the treated Michigan sample. ln both treated groups, lateral cephalometric radiographs were obtained before the Herbst appliance was cemented and at the end of the fixed appliance phase, The first comparison involved the Brazil group and the untreated controls, which demonstrated that the association of the Herbst appliance followed by fixed Straight-wire appliances provoked positive effects on the dentofacial complex, improving pre-existing maxillo-mandibular relationships, besides increasing dentoalveolar compensations which contributed to correct the malocclusion. The second comparison, involved the Brazl1ian and North-American patients treated with the same protocol. Although the pre-treatment comparison showed that the two groups were not similar in all aspects, they presented almost identical therapeutic modifications, which indicate that the effect of' treatment was very similar. These results point out that, in Class ll treatment, the combination of Herbst/Straight-wire mechanics produce consistent and systematic effects, correcting or minimizing possible skeletal imbalances

Motor profile of students with dyslexia

In the presence of developmental dyslexia, there is high probability of motor difficulties being present as well purposes: The purposes of this study were to characterize and compare the motor performance of students with dyslexia with students with good academic performance and to identify the presence of the DCD (developmental coordination disorder) co-occurring with developmental dyslexia. A total of 79 students participated in the research, both genders, from 8 to 11 years old, from 3rd to 5th grades, and were divided into Group I: 19 students with developmental dyslexia and Group II: 60 students with good academic performance. All the students were assessed using “The Bruininks-Oseretsky Test of Motor Proficiency” (second edition), to measure the motor skills and the pattern and differences between groups. The results of this study showed that the motor performance of Group II students was superior to the performance of students of Group I in almost all motor areas assessed but both groups performed less well than they should have for their chronological age. The results of this study indicate that occupational therapists, speech therapists and educators need to be aware of the presence of motor impairments and the need for early intervention in both the academic and clinical environments, in order to ensure that early identification and diagnosis of possible co-occurrences, such as DCD, and the impact on learning to guarantee more appropriate clinical and educational assistance for this population. This may also indicate that increased exposure to movement may be important to limit some of the secondary health consequences in children in Brazil.

Habilidades perceptivas visuais e qualidade de escrita de escolares com dislexia

OBJECTIVE: This study aimed to characterize and compare the visual perceptual skills and writing quality of students with dyslexia, with good academic performance, and to relate the perceptual visual motor skills and the writing quality of students with dyslexia, with good academic performance. METHODS: 40 students participated in this study; 35 males and 5 females, from 8 to 11 years and 11 months, who attended from the 3rd to 5th grade level of public municipal schools of Marília-SP, divided into two groups: Group I (GI) comprised 20 students with interdisciplinar diagnoses of dyslexia, and Group II (GII) comprised 20 students with good academic performance. The Visual Perceptual Skills Test - TVPS-3 and the Disgraphy Scale were applied. RESULTS: The results obtained from this study showed that the students with dyslexia presented difficulties in visual skills concerning discrimination and memory. Besides discrimination and memory skills, it was observed inferior performance concerning the relation visual spacial skills and steady form, and inferior performance in all the visual skills, when compared to the chronological age. However, the group of students with good academic performance has also presented inferior performance concerning the relation visual spacial skills and steady form. CONCLUSIONS: The study mentions that maybe schools do not invest sufficiently in activities which envolve visual experiences necessary for the enhancement of reading and writing. Although statistically significant difference was not observed between the groups concerning disgraphy, it iwas possible to observe that a higher amount of students presented disgraphy.

Efeito da prática do futebol no desempenho em agilidade, velocidade e coordenação de meninos na categoria dentinho ou sub 11 (10 e 11 anos de idade)

In Brazil, the practice of Soccer is encouraged very early. It is common remark that parents enroll their sons into soccer schools, promoting the involvement of these children in formal practice. However, there are not many studies that assess the effects of this practice in the physical capacities of children. Thus, the question that guides this study is: children who practice soccer systematically present better development of physical, especially agility, coordination and speed? The objective of this study was to compare the performance in velocity tests, agility and coordination of boys of 10 and 11 years, category dentinho or Sub-11, practitioners of soccer in schools and non practicing. The study included male children, born in 1997 and 1998, formed two groups: group of practitioners of soccer and group of non practicing. To belong to the group of practitioners, the child was regularly engaged for at least 1 year, with 1 hour daily and 2 to 3 times per week. The participants of the group of non practicing were not involved in regular practice of soccer and were paired in weight and stature with participants of the group of practitioners of soccer. Each participant was individually assessed in neutral environment and without foreign interference. For the assessment of the agility, was utilized the (shuttle run) test. The race test 30 meters stopped was employed for the assessment of the speed. The test of fiddling between the cones was employed to measure the coordination. The time spent to perform 1 attempt to each test was used for the comparison between groups. These data were treated, initially, by descriptive statistics (mean and standard deviation) and, subsequently, were compared by means of Anova, for independent samples. The significance level was maintained at 5%. Through analysis of the results the conclusion is that the regular practice ...(Complete abstract click electronic access below)

Avaliação do índice de Litle em indivíduos que utilizaram o aparelho funcional T4K

The study aimed to assess the degree of dental crowding correction on the lower anterior region of patients treated with T4k functional appliance using Little’s irregularity index. Twenty caucasian patients of both gender (10 female and 10 male) were selected. They featured malocclusion Class I and II in mixed dentition, with chronological age between 5.7 and 11 years. The treatment lasted from 1 year and 11 months up to 3 years and 11 months. Lower anterior crowding was measured using Little’s irregularity index. Measurements were obtained on study models achieved before and after functional orthopedic therapy, using a digital caliper in millimeters and placed parallel to the occlusal plane. Overjet and overbite measurements were also performed using a caliper. Results demonstrated that the therapy provided significant decrease in overjet (average = 1.55 mm) and also in the irregularity index (average = 1.23 mm). There was a nonsignificant raise in overbite. There was no relation between the studied variables and the treatment period or even with the patient’s age in the beginning of the therapy. The treatment with T4k resulted on reduction and improvement of dental crowding.
