The control of stances such as the upright stance seems not to have a purpose in itself; this control could facilitate the execution of other simultaneous tasks, the so-called suprapostural tasks. The goal of this study was to determine the effects of saccadic eye movements on the control of posture. Twelve adult participants had their body oscillations analyzed while standing upright, for 70 s, in the postural conditions of feet apart and feet together, performing fixation in the central target or horizontal saccadic movements, in the conditions slow (0,5 Hz) and fast (1,1 Hz). The results showed that saccadic movements, independently of their frequency, strongly reduced trunk and head oscillations in the anterior-posterior (AP) axis. In this axis, there was an effect of feet position only in head oscillation. In the medio-lateral (ML) axis, the results showed a strong effect of feet position with body oscillation decreased in the condition of feet apart. The effect of the visual task in the ML axis occurred only for trunk oscillation, not reaching significance level in the pairewise comparisons. In the AP axis, the data corroborate a facilitatory explanation of the control of posture: the reduction in body oscillation limited the variations of the stimulus image projected on the retina, facilitating the execution of saccadic movements as compared to fixation. In the ML axis, the effect of reducing the basis of support was more evident than the effect of saccadic movements, suggesting that the available resources were used primarily for the postural task in detriment of the visual task. Additionally, aspects like attentional focus and sensory information pick up are discussed as mechanisms involved in this task

In massal rearing of natural enemies with the goal of biological control, the procedures adopted for establishment and maintenance of the individual founders of the colonies may have undesirable effects on population genetic structure of laboratory. This situation influences the success of rearing and effectiveness in the field. The objective of this study was to evaluate, along of generations two laboratory populations (Jaboticabal and Piracicaba) of Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae), founded with different numbers of adults (1, 5, 10, 15 and 20 couples), the frequency of morphological variants, size of wings and eye color, such as parameters for inferences about the homozygosity degrees. For eye color were assessed the frequency, while for the size of wings was measured the width and the length of the right mesothoracic wings. The eye color variants for C. externa populations may be monitored in the laboratory aiming at detecting inbreeding, whereas the measurements of length and width of wings should not be adopted for this purpose.

The aim of this research was to verify the accuracy of the prediction trace. Records in 15 patients admitted for orthognathic surgical treatment were analysed. Predictive and postoperative positíons of maxilla were compared with linear measurements. Statistically significant difference between predicted and postoperative position were demonstrated, but the prediction trace revealed to be very useful to help in decision of direction of movements, easy to do at low cost

This research evaluated the surgical stabilily in patients with mandibular prognathism and retrognathism in which was used sagital split technic to correct those detormities. Twelve patients were selected from the clinic of only one experienced surgeon. Six patients presenter a Class III 6 a Class II molar relationship. A comparative cefalometric analysis using linear and angular measurements was performed of pre-surgery, imediate pós-surgery and 1 year follow-up. The following conclusions were obtained. 1 The Dal Pont sagital split technic modified by Epker to correct mandibular prognathisn and retroghnatism is a stable technic and must be indicated to correct those deformities. 2 Small relapses are easily corrected by the post-surgical orthodontic treatment. 3 A small over correction is advised in cases of large mandibular advancements or set bascks. 4 In those cases which a large amount of mandibular retrusion on advancement need to be performed, a combination of maxillary and mandibular surgery should be used. Rigid fixation technic is also indicated in those cases

The indications for adenotonsillectomy in pediatric patients have changed considerably during the 90th decade. Local or systemic complications of the adenoid or tonsil hypertrophy itself have now been substituted by signs of obstructive ventilatory disturbances, including obstructive sleep apnea as the major indications for surgery. Objective: This study analyses the clinical profile of children submitted to adenotonsilectomy in their pre and postoperative state, at Botucatu Medical School-State University São Paulo, UNESP. Methods: 332 children of both genders, aged 1 to 12 years, who underwent adenotonsillectomy between 1999 and 2004, were studied, focused on epidemiological profile, pre and postoperative (1 month) symptoms, obtained from medical records. Height and weight were compared to brazilian normal age related values. Results: We found a predominance of the male gender, except in he group aged from 10 to 12 years. Considering wheight and height, we found important failure to thrive, mostly for height deficit. Among clinical aspects, we found a significant reduction in obstructive symptoms like snoring or apneia (p<0001) in the postoperative period. Conclusion: Our results were similar to the literature findings of patients clinical profile. The major indication for adenotonsillectomy in our service was clinical diagnosis of obstructive sleep apnea.

The objective of the literature review showing their main biological properties involved in the tissue repair process and its therapeutic potential in the prevention , control and treatment of infection in oral surgeries . To carry out this study , a search of the PubMed database . 13 articles that met the inclusion criteria were found . Antimicrobial properties , antiálgicas , anti-inflammatory , imunu - stimulants , oxygenation and neoangiogenesis were attributed to ozone in several studies . And indications such as the treatment of alveolitis , osteomyelitis , osteonecrosis , wound healing in skin and mucosa and antisepsis been suggested. However , many of its effects have not been well understood. The doses and concentrations for their use are not standardized . Studies to establish doses and periods of administration are still needed for increasingly traumatic and biologically effective therapies are found to practice dentistry .

Melanoma subungueal in situ tratado com cirurgia funcionalHamilton Ometto StolfI, Hélio Amante MiotI, Nilton de Ávila ReisIIDepartamento de Dermatologia e Radioterapia, Universidade Estadual Paulista (Unesp)INTRODUÇÃOO melanoma subungueal representa aproximadamente 2% a 3% dos melanomas cutâneos em pacientes caucasianos1 e 20% em pacientes negros2 ou asiáticos.3A exposição solar, tida com principal fator de risco para o melanoma cutâneo,4 parece desempenhar papel secundário no desenvolvimento da variante subungueal,5 uma vez que a radiação ultravioleta dificilmente penetra no leito ungueal. Além disso, nevos subungueais como lesões precursoras são extremamente raros.6Os polegares e háluces são os mais acometidos, sendo o polegar responsável por 56% dos casos entre todos os dedos e o hálux por 86% dos dedos dos pés.7A confirmação do diagnóstico é feita a partir do exame anatomopatológico da lesão, geralmente localizada na matriz ou leito ungueal. A verificação histológica do melanoma subungueal é frequentemente postergada por conta do atraso no diagnóstico clínico,8-10 gerando piora do prognóstico.O prognóstico geralmente é ruim: as taxas de sobrevida real de cinco anos variam entre 16% a 20%, podendo atingir até 80% se consideradas taxas de sobrevida estimada.2,3,11-18RELATO DE CASOPaciente de 44 anos, do sexo feminino, professora, com queixa de aparecimento de mancha na unha do hálux direito há cinco anos. Relata aumento progressivo lento na largura da faixa. Ao exame dermatológico, apresentava faixa de melanoníquia extensa, irregular, bordas mal definidas e estria de pigmentação mais acentuada em uma das margens do leito ungueal do hálux direito (Figura 1). Exame dermatoscópico (aparelho Dermalite II Pro, aumento de 10 vezes) confirmou faixas irregulares e cores variadas de hiperpigmentação.Foi realizada a avulsão parcial da lâmina ungueal e incisão na prega ungueal lateral para visualização do local da origem da pigmentação no leito ungueal,
