Este estudo teve como objetivo desenvolver uma metodologia de construção de um Painel de Monitoramento e Avaliação da Gestão do Sistema Único de Saúde (SUS). O processo participativo utilizado e a sistematização realizada permitiram identificar uma estratégia efetiva para a construção de instrumentos de gestão em parceria entre pesquisadores, instituições acadêmicas e gestores do SUS. A sistematização final do Painel selecionou indicadores da gestão do SUS em termos de Demandas, Insumos, Processos, Produtos e Resultados de forma a disponibilizar um instrumento simples, ágil e útil para a avaliação em qualquer instância de gestão e mais transparente e de mais fácil comunicação com todos os interessados na tomada de decisão. Tomar a gestão do SUS como objeto destes processos e práticas em seus aspectos normativos possibilitou o diálogo entre teorias sistêmicas e aquelas que consideram a centralidade do ator social no processo de tomada de decisão.

The main purposes of this manuscript are to provide an overview of various modalities of surgical correction of anterior plagiocephaly and to emphasize their differences with the classic open frontal-orbital advancement. Advancement of technology provides development of many other ways to achieve the same results. The authors describe the classic open frontal-orbital advancement and compare with other proposed techniques for correction of frontal plagiocephaly. The main limitation of the use of new forms of treatment of the anterior plagiocephaly is the age of the patient. There is still no consensus on criteria for quantitative evaluation of surgical results, and new forms of treatment do not present results with long follow-up. Frontal-orbital advancement is the preferred procedure to correct unicoronal synostosis due to its universal indication regardless of the age and degree of deformation of the anterior plagiocephaly.

The aim of this study was to characterize and compare the spectral behavior of different soil classes obtained by orbital and terrestrial sensors. For this, an area of 184 ha in Rafard (SP) Brazil was staked on a regular grid of 100x100 m and soil samples were collected and georeferenced. After that, soil spectral curves were obtained with IRIS sensor and the sample points were overlaid at Landsat and ASTER images for spectral data collection. The soil samples were classified and mean soil curves for all sensors were generated by soil classes. The soil classes were differentiated by texture, organic matter and total iron for all sensors studied, the orbital sensors despite the lower spectral resolution, maintained the characteristics of the soil and the curves of reflectance intensity.

Introduction: Orbital infections may result in permanent morbidity because of the severity of infection. Furthermore, delayed diagnosis or treatment of orbital infections can lead to intracranial complications and even death. The majority of orbital infections develop from paranasal sinus infections, cutaneous infections, and periorbital trauma. Dacryocystitis and odontogenic infection are also accounted as potential etiologies but are scarcely reported in scientific literature. Methods: The patient revealed a history of having endodontic treatment on left maxillary second molar performed 2 weeks previously. Moreover, she exhibited signs of facial pain accompanied by sinusitis symptoms, fever, and nasal obstruction the week after this endodontic procedure. The patient presented proptosis, impairment of ocular motility to the right side, facial tenderness, palpebral erythema, and referred decreased visual acuity. Intraoral exam revealed root fragments of left maxillary first molar and an extensive carious lesion on left maxillary second molar. Computed tomography enabled the observation of frontal sinus, left-sided maxillary, opacity of sphenoidal and ethmoidal sinuses, and apical lesion of left maxillary first and second molars, all suggesting the presence of their apex in the maxillary sinus. In addition, images revealed ocular proptosis and presence of high-density areas suggestive of pus in the medial orbital wall region. Results: The patient was submitted to surgical drainage under general anesthesia approximately 8 hours after the clinical evaluation. Conclusions: Early detection of orbital infection, proper diagnostic tests, and treatment may provide successful outcomes of this rarely occurring disease. (J Endod 2012;38:1541-1543)

Epidermal or epidermoid cysts usually are benign, solitary-growing masses located in the mid- or lower dermis. They are believed to derive from pilosebaceous units and are lined with an epidermis-like epithelium including a granular cell layer.(1) The occurrence of multiple epidermal cysts on the scalp of nonsyndromic patients is extremely rare. Although the presence of squamous cell carcinoma in the wall of an isolated epidermoid cysts is well documented in the dermatological literature,(2,3) the authors are not aware of any article in the English literature describing orbital invasion by a carcinoma developed in isolated or multiple epidermoid cysts.

BACKGROUND AND PURPOSE: DON, a serious complication of GO, is frequently difficult to diagnose clinically in its early stages because of confounding signs and symptoms of congestive orbitopathy. We evaluated the ability of square area measurements of orbital apex crowding, calculated with MDCT, to detect DON. MATERIALS AND METHODS: Fifty-six patients with GO were studied prospectively with complete neuro-ophthalmologic examination and MDCT scanning. Square measurements were taken from coronal sections 12 mm, 18 mm, and 24 mm from the interzygomatic line. The ratio between the extraocular muscle area and the orbital bone area was used as a Cl. Intracranial fat prolapse through the superior orbital fissure was recorded as present or absent. Severity of optic nerve crowding was also subjectively graded on corona! images. Orbits were divided into 2 groups (with or without clinical evidence of DON) and compared. RESULTS: Ninety-five orbits (36 with and 59 without DON) were studied. The CIs at all 3 levels and the subjective crowding score were significantly greater in orbits with DON (P<.001). No significant difference was observed regarding intracranial fat prolapse (P=.105). The area under the ROC curves was 0.91, 0.93, and 0.87 for CIs at 12, 18, and 24 mm, respectively. The best performance was at 18 mm, where a cutoff value of 57.5% corresponded to 91.7% sensitivity, 89.8% specificity, and an odds ratio of 97.2 for detecting DON. A significant correlation (P<.001) between the CIs and VF defects was observed. CONCLUSIONS: Orbital Cls based on area measurements were found to predict DON more reliably than subjective grading of orbital crowding or intracranial fat prolapse.

Purpose: To quantify the risk of new diplopia in inferomedial orbital decompression performed for cosmetic reasons. Methods: Retrospective analysis of 114 patients with Graves orbitopathy who underwent an inferomedial orbital decompression. No patient had diplopia in any of the gaze positions or optic neuropathy. A single coronal slice 9 mm posterior to the lateral orbital rim was employed to quantify the muscular index of the extraocular recti and of the superior complex. A control group of 56 patients imaged for other reasons were also measured. After surgery the oculomotor status of all patients who complained of diplopia and of 51 patients free of diplopia was measured with the prism and cover test in the primary and secondary gaze positions. Results: The rate of new-onset diplopia was 14.0% (16 patients). Eye deviations were confirmed in 14 patients. Of these, 10 had significant strabismus that warranted surgical or prism treatment. Most patients had esotropia associated with small vertical deviations. The size of the medial and inferior recti was significantly associated with the development of diplopia. The estimated odds for the appearance of diplopia in patients with muscle enlargement was 12.76 (medial rectus) and 5.21 (inferior rectus). Small-angle deviations were also detected in 27.4% of patients who did not experience diplopia. Conclusions: Medial and inferior recti enlargement is a strong predictor of new-onset diplopia. A large number of patients who do not report diplopia also present with small-angle deviations. (Ophthal Plast Reconstr Surg 2012;28:204-207)

A 12-year-old girl had a 6-year history of a large soft-tissue mass in her left orbit. The tumor biopsy was previously performed elsewhere when she was 7 years old, but no treatment was offered at that time. Later, the tumor was completely excised, and histologic examination revealed a mesenchymal neoplasia with typical hemangiopericytoma features. At 9 months of follow up, no evidence of local recurrence or metastasis was seen.

Seven sides of cadaver heads were used to compare the surgical exposures provided by the mini-modified orbitozygomatic (MOz) and supra-orbital (SO) approaches. The Optotrak 3020 computerized tracking system (Northern Digital, Waterloo, ON, Canada) was utilized to evaluate the area of anatomical exposure defined by six points: (1) ipsilateral sphenoid ridge; (2) most distal point of the ipsilateral middle cerebral artery (MCA); (3) most distal point of the ipsilateral posterior cerebral artery (PCA); (4) most distal point of the contralateral PCA; (5) most distal point of the contralateral MCA; and (6) contralateral sphenoid ridge. Additionally, angles of approach for the ipsilateral MCA bifurcation, ipsilateral ICA bifurcation, basilar artery tip, contralateral MCA and ICA bifurcation and anterior communicating artery (AcomA) were evaluated, first for SO and then for MOz. An image guidance system was used to evaluate the limits of surgical exposure. No differences in the area of surgical exposure were noted (p > 0.05). Vertical angles were significantly wider for the ipsilateral and contralateral ICA bifurcation, AcomA, contralateral MCA and basilar tip (p < 0.05) for MOz. No differences in horizontal angles were observed between the approaches for the six targets (p > 0.05). There were no differences in the limits of exposure. MOz affords no additional surgical working space. However, our results demonstrate systematically that vertical exposure is improved. The MOz should be performed while planning an approach to these regions and a wider exposure in the vertical axis is needed. (C) 2012 Elsevier Ltd. All rights reserved.

Purpose: to describe the proposal of monitoring children in the first year of life, who were not identified in the newborn hearing screening program but had risk factors for hearing loss. Method: the study included 258 risk children who had obtained the result “pass” in the Universal Newborn Hearing Screening Program of Hospital Santa Isabel – Bauru/SP, from June to November 2008. It was applied by the telephone, a validated questionnaire in a previous study, containing questions about hearing and language. For each question there were two possible answers: “yes” or “no” and we considered “failure” to obtain at least one “no” answer. With such result, the child was scheduled to perform an immediate hearing evaluation. Results: the questionnaire was applied with 169 families; with the others, there was no contact. From the total, 164 (97,04%) obtained “passed” and five (2,96%) “failed”. Between these five children, only three showed up for hearing evaluation and one had no disorders; two presented conductive hearing loss. It was observed distinct prevalence among the risk factors and there was no relation (p>0,05) of the risk factors with the evasion in the monitoring process. Conclusion: the monitoring through a questionnaire applied by telephone proved to be feasible, however, it is necessary to develop strategies to support their execution.

O objetivo do presente estudo foi à monitoração dos parâmetros laboratoriais como hemograma, enzimas hepáticas alanina aminotransferase (ALT) e gama-glutamiltransferase (GGT), glicemia e proteinograma sérico, e avaliar o efeito da idade em gatos sem raça definida durante a fase neonatal. Vinte gatos machos e fêmeas foram utilizados a partir do terceiro dia de vida até o 38º dia de idade. As amostras de sangue foram colhidas semanalmente e as análises laboratoriais (hemograma, enzimas hepáticas, glicemia e proteinograma sérico) realizadas no 3º, 10º, 17º, 24º, 31º e 38º dia de idade. Os resultados exibiram efeito significativo da idade sobre a contagem total de eritrócitos, concentração de hemoglobina, volume globular, volume corpuscular médio, concentração de hemoglobina corpuscular média, leucócitos totais, neutrófilos, eosinófilos e basófilos. Nenhum efeito foi observado em células como linfócitos, monócitos ou na concentração sérica de glicose. A análise das modificações ocorridas nos parâmetros laboratoriais durante a fase neonatal reflete o desenvolvimento fisiológico do filhote e contribui para o conhecimento do processo adaptativo em gatos neonatos durante o primeiro mês de vida, sendo útil para a avaliação clínica, diagnóstico e tratamento das doenças neonatais.

OBJETIVO: Revisar a literatura científica para verificar como a vigilância do desenvolvimento infantil vem sendo realizada no Brasil. FONTES DE DADOS: Pesquisa em bases de dados (PubMed, Medline, SciELO e Banco de Teses da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior) sobre estudos das práticas médicas em relação à vigilância e ao monitoramento do desenvolvimento infantil no Brasil, de 2000 a 2011. Os termos usados para pesquisa foram: vigilância de desenvolvimento infantil, intervenção precoce, triagem de desenvolvimento e testes de triagem de desenvolvimento. Foram encontrados dez textos referentes ao tema em estudo. Artigos originais, de revisão e teses foram revisados, bem como as listas de referências das publicações sobre o assunto. SÍNTESE DOS DADOS: Os estudos sobre a prática do monitoramento do desenvolvimento infantil no Brasil apontam uma importante falha, desde a formação do médico pediatra até a prática clínica, em relação a este tema. CONCLUSÕES: Há necessidade urgente, principalmente frente a uma população emergente de prematuros, que os pediatras façam uma reciclagem do conhecimento sobre o desenvolvimento infantil.

OBJETIVO: Analisar os fatores de risco e proteção para Doenças Crônicas Não Transmissíveis - DCNT nas capitais do Brasil. METODOLOGIA: Foram analisadas informações provenientes do sistema de vigilância de fatores de risco e proteção para DCNT por inquérito telefônico - VIGITEL, em 2008. A amostra foi composta por 54 mil entrevistas sendo as frequências apresentadas para o conjunto das capitais por sexo, faixa etária e escolaridade. RESULTADOS: O estudo mostrou diferenças na prevalência de fatores de risco e proteção de DCNT entre sexos, idade e escolaridade. Os homens apresentaram maiores frequências de fatores de risco como fumo, excesso de peso, consumo de refrigerantes, carnes com excesso de gordura e bebidas alcoólicas. Os homens praticam mais atividade física no lazer. As mulheres se alimentam melhor e referem mais diagnóstico médico de doenças, como hipertensão arterial, dislipidemia e osteoporose, além de estado de saúde ruim. Em geral, os fatores de risco são mais frequentes na população de menor escolaridade. DISCUSSÃO: Estas informações devem redirecionar a implementação das políticas públicas com foco em um modo de viver mais saudável e escolhas individuais mais adequadas por parte da população adulta brasileira.

Objetivo: Estabelecer um padrão de crescimento tumoral (volume) em ratos Wistar submetidos ao modelo C6 de glioblastoma multiforme por meio de imagens de ressonância magnética para posterior verificação de redução de volume tumoral com a terapia de magnetohipertermia. Métodos: Para o modelo C6, utilizamos ratos Wistar, machos, jovens, pesando entre 250 e 300 g. Após anestesiados (cetamina 55 mg/kg e xilazina 11 mg/kg) foram injetadas estereotaxicamente células tumorigênicas linhagem C6 suspensas em meio de cultura (105 células em 10 µL) no córtex frontal direito (coordenadas a partir do bregma: anteroposterior = 2,0 mm; látero-lateral = 3,0 mm; profundidade = 2,5 mm) com uma seringa Hamilton. No Grupo Controle, houve a injeção do meio de cultura sem as células. Posteriormente, foram feitas imagens mediante a técnica de imagem por ressonância magnética em 14, 21 e 28 dias após a injeção em um escâner de imagem por ressonância magnética 2.0 T (Bruker BioSpec, Germany). Para o exame, os animais foram anestesiados com cetamina 55 mg/kg e xilazina 11 mg/kg. Multifatias coronais foram adquiridas utilizando uma sequência spin-echo padrão com os seguintes parâmetros: TR/TE = 4,000 ms/67,1 ms, FOV = 3,50, Matrix 192, slice thickness = 0,4 mm e slice separation = 0 mm. Resultados: A análise das imagens de ressonância magnética do tumor possibilitou a clara visualização da massa tumoral, sendo possível ainda estabelecer parâmetros de volume tumoral nos diferentes dias analisados. O volume de 14 dias após a indução do foi de 13,7 ± 2,5 mm3 . Aos 21 dias, o volume alcançado foi de 31,7 ± 6,5 mm3 e, aos 28 dias, a massa tumoral atingiu 122,1 ± 11,8 mm3 . Conclusão: Estes resultados mostraram a possiblidade de avaliação do volume tumoral no modelo C6 em ratos, o que possibilitará, no futuro, a aplicação da terapia de magnetohipertermia bem como verificação de seus resultados.
