Facial growth evaluation of complete unilateral cleft lip and palate operated patients: a cleft reference center in Paraíba, Brazil, using the GOSLON yardstick

Objectives: To evaluate the surgical outcomes of patients with complete unilateral cleft lip and palate (CUCLP) operated on by a single surgeon of the cleft reference center of the Lauro Wanderley University Hospital at the Federal University of Paraiba. Methods: Forty-four individuals' dental casts diagnosed with CUCLP, born between 1995 and 2002, mean age of 11 years, were evaluated by three calibrated orthodontic specialists and scored by the Great Ormond Street, London and Oslo (GOSLON) yardstick on two occasions. The scores were compared with those observed in other centers around the world. The Kappa test was applied to evaluate the intra- and inter-examiner agreement. Descriptive statistics was applied for the GOSLON yardsticks core. Results: The mean GOSLON score was 2.75. For the GOSLON yardstick, 43.2 % of the sample presented scores 1 and 2, 31.8 % had score 3, and 25 % were with scores 4 and 5. There was very good intra- and inter-examiner Kappa agreement in the application of the GOSLON yardstick. Conclusions: The data suggest favorable outcomes, with 75 % of cases with no need of orthognathic surgery. The Kappa values confirmed the high reproducibility of the GOSLON yardstick. © 2013 Springer-Verlag Berlin Heidelberg.

Facial hemangiossarcoma in a blue-fronted amazon parrot (Amazona aestiva)

Here we describe the first case report of an hemangiosarcoma in a male Blue-fronted amazon parrot (Amazona aestiva). The mass was localized near the inferior portion of the right orbit. A fine needle aspiration biopsy (FNAB) was performed and a presuntive diagnosis of hemangioma/hemangiosarcoma was established. Further histopathological evaluation revealed a mesenchymal neoplasm composed basically by well formed vascular channels lined by pleomorphic endothelial cells. Thus, the final diagnosis was a well-differentiated cutaneous hemangiosarcoma.

Genetic parameter estimates and principal component analysis of breeding values of reproduction and growth traits in female Canchim cattle

Phenotypic data from female Canchim beef cattle were used to obtain estimates of genetic parameters for reproduction and growth traits using a linear animal mixed model. In addition, relationships among animal estimated breeding values (EBVs) for these traits were explored using principal component analysis. The traits studied in female Canchim cattle were age at first calving (AFC), age at second calving (ASC), calving interval (CI), and bodyweight at 420 days of age (BW420). The heritability estimates for AFC, ASC, CI and BW420 were 0.03±0.01, 0.07±0.01, 0.06±0.02, and 0.24±0.02, respectively. The genetic correlations for AFC with ASC, AFC with CI, AFC with BW420, ASC with CI, ASC with BW420, and CI with BW420 were 0.87±0.07, 0.23±0.02, -0.15±0.01, 0.67±0.13, -0.07±0.13, and 0.02±0.14, respectively. Standardised EBVs for AFC, ASC and CI exhibited a high association with the first principal component, whereas the standardised EBV for BW420 was closely associated with the second principal component. The heritability estimates for AFC, ASC and CI suggest that these traits would respond slowly to selection. However, selection response could be enhanced by constructing selection indices based on the principal components. © CSIRO 2013.

Facial pain associated with fibromyalgia can be marked by abnormal neuromuscular control: A cross-sectional study

Background. Temporomandibular disorder (TMD) development in fibromyalgia syndrome (FMS) is not yet fully understood, but altered neuromuscular control in FMS may play a role in triggering TMD. Objective. The purpose of this study was to verify the association between neuromuscular control and chronic facial pain in groups of patients with FMS and TMD. Design. A cross-sectional study was conducted. Methods. This study involved an analysis of facial pain and electromyographic activity of the masticatory muscles in patients with FMS (n=27) and TMD (n=28). All participants were evaluated according to Research Diagnostic Criteria for Temporomandibular Disorders and surface electromyography (SEMG). Myoelectric signal calculations were performed using the root mean square and median frequency of signals. Results. The data revealed premature interruption of masticatory muscle contraction in both patient groups, but a significant correlation also was found between higher median frequency values and increased facial pain. This correlation probably was related to FMS because it was not found in patients with TMD only. Facial pain and increased SEMG activity during mandibular rest also were positively correlated. Limitations. Temporal conclusions cannot be drawn from the study. Also, the study lacked a comparison group of patients with FMS without TMD as well as a control group of individuals who were healthy. Conclusions. Altered neuromuscular control in masticatory muscles may be correlated with perceived facial pain in patients with FMS. © 2013 American Physical Therapy Association.

Changes on facial profile in the mixed dentition, from natural growth and induced by Balters' bionator appliance

Objective: The purpose of this study was to evaluate the facial profile changes induced by Balters' bionator appliance in Class II division 1 patients, at mixed dentition stage. Methods: The sample consisted of 28 prepubertal individuals at stages 1 and 2 of skeletal maturation (CVM), which were divided in two groups. The experimental group consisted of 14 individuals (7 boys and 7 girls, initial mean age of 8y12m) which were treated with Balters' bionator appliance for 14.7 months. The effects of treatment were compared to a control group of 14 subjects (7 boys and 7 girls, initial mean age of 8y5m) with Class II malocclusion, division 1, not orthodontically treated, which were followed up for 15.4 months. The statistical analysis was performed using Student's t test, at a significance level of 5%. Results: The results showed that the Balters' bionator appliance promoted a significant increase on the mentolabial angle, in addition to demonstrating a tendency to reduce the facial skeletal convexity, to restrict the maxillary growth and to increase the nasolabial angle and the lower anterior facial height. Conclusion: It can be concluded that the Balters' bionator appliance improved the facial profile of children treated at mixed dentition stage. © 2013 Dental Press Journal of Orthodontics.
