A polimicrogiria (PMG) é uma malformação do córtex cerebral causada por falhas no seu desenvolvimento, caracterizando-se por um número excessivo de pequenos giros e laminação anormal, dando à superfície cortical uma aparência irregular e grosseira. A gravidade de suas manifestações clínicas se relaciona diretamente com a extensão da malformação e das regiões cerebrais afetadas, sendo que a presença de lesões bilaterais ou unilaterais extensas indica um pior prognóstico. Uma das síndromes de polimicrogiria mais freqüentes e, conseqüentemente, mais bem descritas clinicamente, é a polimicrogiria perisylviana bilateral (PPB). Essa forma de PMG atinge a região que tange a fenda Sylviana, podendo apresentar-se tanto unilateralmente quanto em ambos os hemisférios. Vários genes têm sido relacionados a diferentes formas de polimicrogiria, são eles AFF2,TUBA1A, TUBB2B e TUBA8, SRPX2 e WDR62. Estes genes já foram estudados pelo nosso grupo de pesquisa em um grupo de pacientes compostos de casos familiares e esporádicos, acometidos em sua maioria pela forma perisylviana de PMG. Nenhuma variante deletéria foi identificada nestes genes. Recentemente um novo gene foi implicado na etiologia molecular das PMG, o TUBB3. O gene em questão pertence à mesma família de TUBA1A, TUBB2B e TUBA8 e codifica uma proteína de ligação aos microtúbulos, tendo importante papel na formação do fuso. Além deste gene, também tem sido descritas alterações genômicas, denominadas de Copy Number Variations (CNV), estas variações estruturais tem sido associadas com diversos distúrbios neurológicos, que vão desde transtornos psiquiátricos até malformações do córtex cerebral como a PMG. Desta forma, o objetivo deste trabalho foi analisar a existência de alterações de ponto deletérias no gene TUBB3 em pacientes com PMG e também, o envolvimento de CNVsna etiologia deste tipo de malformação ...

The correction of a Class III malocclusion in adult patients is one of the major challenges in orthodontics due to facial deformities occurring during the unfavorable growth of this kind of pattern, as well as the treatment options capable of producing facial changes aesthetically acceptable and adequate for today's beauty standards. One acceptable alternative treatment is the removal of a lower incisor. For a Class III correction through a lower incisor extraction a thorough analysis and planning must be carried out by taking into consideration the amount of overjet and overbite, periodontal condition of the teeth and the possibility of obtaining a good dental occlusion with acceptable facial aesthetics. Will be presented two case reports of patients presenting an anteroinferior crowding, Class III malocclusion condition. The treatment through a lower incisor extraction and the reasons why this treatment was adopted will be discussed.

Introduction: The configuration and dimensions of the upper airway are determined by anatomical structures such as soft tissues, muscles and craniofacial skeleton, composing or surrounding the pharynx. Anatomical abnormalities of the soft tissues and / or craniofacial skeleton may become more narrow upper airway. The orthognathic surgery, which is used in the correction of dentoskeletal deformities, also causes changes in the upper airway. Objective: In view of the facts presented, this article aims to review the literature on the changes of the upper airway in patients’ class III undergoing orthognathic surgery. Methodology: International Literature on Health Sciences (Pubmed ) and Port Journals CAPES original and review published between 1990 and 2010, in two bibliographic databases articles were selected. Results: thirty-nine (39) articles were selected for writing this review. Conclusion: The upper airway deformity and dental- skeletal class III should be carefully evaluated prior to orthognathic surgery and whenever surgical planning permit should prefer the maxillary advances to mandibular setbacks

Purpose: The aim of this study was to compare occlusal plane angulation measured in two different types of semi-adjustable articulators with that obtained on the lateral cephalometric radiograph. Materials and Methods: 20 patients due to undergo orthognathic surgery had dental casts mounted in two different types of semi-adjustable articulators through face bow transfer from the position of the maxilla and occlusal recording to the mandible. After mounting, the inclination of the occlusal plane in the articulators was measured and compared with the inclination measured at on both articulators and compared with the inclination measured on the lateral cephalometric radiographs and between the articulators themselves. The results obtained werestatistically analyzed. Results: Mean angulation values for the Bio Art (7.55º) and Kavo (-5.70º) articulators differ by 13.25º, which is statistically significant (p=0.00). When individually compared to the lateral cephalometric radiograph (5.075º), the Bio Art articulator showed more similar angulation values, with a difference of 2.475º, while the Kavo articulator presented a difference of 10.775º. Conclusion: Neither of the models of semi-adjustable articulators accurately reproduced the inclination of the maxillary occlusal plane of patients with dentofacial deformities; the difference between the two articulators tested and the lateral cephalometric radiograph was lower for the Bio Art than for the Kavo articulator.

Citrus aurantium L., commonly known as bitter orange, is widely used in folk medicine, but there is little data in the literature about the s on pregnancy. The aim of the present study was to evaluate the influence of essential oil obtained from fruits of Citrus aurantium on the maternal reproductive outcome and fetal anomaly incidence in rats. Pregnant Wistar rats were randomized into four groups (n minimum = 12 animals/group): G1 = control, G2 to G4 = treated with essential oil from C. aurantium at dose 125, 250 and 500 mg/kg, respectively. Rats were orally treated, by gavage, with plant essential oil or vehicle during pre-implantation and organogenic period (gestational day 0-14). On gestational day 20 the rats were anaesthetized and the gravid uterus was weighed with its contents and the fetuses were analyzed. Results showed that the treated group with 500 mg/kg presented decreased placental weights and placental index, although the treatment with bitter orange essential oil did not show any alteration in maternal reproductive performance, toxicological , changes in ossification sites, and malformation index. In conclusion, the treatment of Citrus aurantium essential oil was not teratogenic and did not alter the maternal reproductive outcome.

Introduction In the Family Health Strategy (FHS), the treatment of Diabetes Mellitus (DM) includes education and lifestyle change strategies. Physiotherapists have a key role in this health setting. Objectives To implement actions of evaluation and guidelines for patients with type 2 DM who attend a Family Health Strategy (FHS), regarding diabetic foot and the practice of regular physical exercise in the control and prevention of the complications of Diabetes Mellitus. Methods 17 individuals from an FHS were evaluated, with the following procedures: clinical and anthropometric parameters, inspection, a questionnaire on diabetic neuropathy, tests of vibratory and tactile sensitivity, muscle function, range of motion, functional analysis, questions about exercise practice and guidance regarding controlling blood glucose and foot care. Results Deformities, dry skin, calluses, dehydration, ulceration, cracking and brittle nails were found. Peripheral neuropathy was not observed; tactile sensitivity was altered in the heel region and the vibratory sense was absent in 5% of individuals. A decrease in functionality of ankle movements was verified. Of the participants, 76% were sedentary, 24% knew about the benefits of practicing regular exercise, 25% had undergone a medical evaluation prior to performing physical exercise and, of these, 25% were supervised by a qualified professional. Discussion The implementation of physiotherapy actions in diabetics from an FHS was important for highlighting the presence of risk factors for diabetic complications. Conclusions Individuals attending the FHS need more information and programs for the prevention of diabetic complications.

The purpose of the present study was to evaluate the incidence of dental anomalies in Brazilian patients with Down syndrome. A sample with 49 panoramic x-rays of syndromic patients aged 3 to 33 years (22 male and 27 female) was used. The characteristics of dental anomalies were observed in the panoramic radiographs in both the primary and permanent dentition, according to the ICD (International Classification of Diseases). The corresponding tables and percentile analysis were elaborated. There was a high incidence of syndromic patients with different types of anomalies, such as taurodontism (50%), proven anodontia (20.2%), suspected anodontia (10.7%), conic teeth (8.3%) and impacted teeth (5.9%). In conclusion, patients with Down syndrome presented a high incidence of dental anomalies and, in most cases, the same individual presented more than one dental anomaly.
