No. of bitstreams: 0 Previous issue date: 2020-01-01 Objective: To assess volume and surface of the mandibular condyle on cone beam computed tomography (CBCT) scans by comparing Class I, II, and III malocclusions. Methods: CBCT scans of 55 patients were assessed to measure ANB angle, condyle volume, and surface by using VistaDent software. The values were compared between the different skeletal malocclusions and correlated to gender and sides. Kruskal–Wallis test was used for comparison of malocclusions and Mann–Whitney test and Wilcoxon test for comparisons of genders and sides. Statistical significance was defined as p

OBJETIVO: o objetivo do presente trabalho foi avaliar a deformação elástica de 14 marcas comerciais submetidas a diferentes meios de descontaminação estirados por 7, 14, 21 e 28 dias. MÉTODOS: três elos de cada elástico foram cortados e mensurados com paquímetro digital para a individualização do estiramento de 50% do tamanho original. Das 20 amostras de cada fabricante, 5 foram diretamente colocadas no template (controle), 5 foram imersas em ácido peracético a 0,2%, 5 foram friccionadas com álcool 70% e 5 foram autoclavadas (121°C / 1 atm / 30 minutos). As amostras permaneceram estiradas no template em saliva artificial a 37°C. Para cada tempo, os elásticos foram removidos, aferidos e descartados. Os dados obtidos foram submetidos à análise estatística (5%). RESULTADOS: observou-se diferença estatisticamente significativa entre as marcas, os meios de descontaminação e os tempos; assim como entre as possíveis interações entre os grupos. As marcas que melhor se comportaram foram a TP Orthodontics e a GAC, seguidas pela Rocky Mountain, American Orthodontics, Orthometric e Aditek, Aditek e Eurodonto, Dentaurum-Tecnident-Ormco-OrthoOrganizes, Abzil-Ormco e OrthoOrganizes, Morelli e Uniden. Verificou-se que o ciclo em autoclave teve compor- tamento semelhante à saliva artificial, alterando menos as propriedades dos elásticos. A deformação plástica foi proporcional ao tempo de estiramento. CONCLUSÃO: existe deformação plástica variando de acordo com a marca, aumentada em função do tempo e influenciada pelo meio de descontaminação utilizado.

A existência de variações na má oclusão entre a relação molar e a relação dos caninos, demonstra a necessidade de agrupar os problemas de maneira clara e precisa. A grande importância dos caninos na oclusão justifica o estabelecimento de uma nomenclatura própria para descrever os desvios da normalidade, contribuindo para uma comunicação entre os ortodontistas, auxiliando no prognóstico, diagnóstico, plano de tratamento e terapêutica. Portanto, o objetivo deste artigo é sugerir uma complementação a classificação de Angle com a introdução da relação sagital de caninos na análise da má oclusão. A nomenclatura, utilizada para a classificação sagital dos caninos, pode contribuir para preencher uma lacuna existente nas classificações das más oclusões quando se avalia a relação mesiodistal dos elementos dentários, proporcionando a avaliação sagital mais precisa dos pacientes.

Objectives: This retrospective study aimed to evaluate the dentoalveolar, skeletal, and soft tissue effects obtained with bone-anchored pendulum appliance in patients with Class II malocclusion. Materials And Methods: A total of 18 patients (4 male, 14 female) at a mean pretreatment age of 14.0 years (+1.08) were enrolled in this study. All patients were treated with the bone-anchored pendulum appliance for an average duration of 4.8 months. Only the active distalization period was evaluated with predistalization and postdistalization lateral cephalograms. Skeletal, dentoalveolar, and soft tissue variables were obtained. Based on these variables, the treatment effects were evaluated with dependent t-test. Results: Correction of Class II molar relationship resulted from distal movement of 3.45 mm and tipping of 11.24° of the first maxillary molars. The premolars were distalized accompanying the molars. Conclusions: The bone-anchored pendulum appliance proved to be an effective method for distalization of maxillary molars in cases that require maximum anchorage, avoiding reciprocal mesial movement of premolars and incisors.

Purpose: To compare four types of mesh regarding visceral adhesions, inflammatory response and incorporation. Methods: Sixty Wistar rats were divided into four groups, with different meshes implanted intraperitoneally: polytetrafluoroethylene (ePTFE group); polypropylene with polydioxanone and oxidized cellulose (PCD); polypropylene (PM) and polypropylene with silicone (PMS). The variables analyzed were: area covered by adhesions, incorporation of the mesh and inflammatory reaction (evaluated histologically and by COX2 immunochemistry). Results: The PMS group had the lowest adhesion area (63.1%) and grade 1 adhesions. The ePTFE and PM groups presented almost the total area of their surface covered by adherences (99.8% and 97.7% respectively) The group ePTFE had the highest percentage of area without incorporation (42%; p

Made available in DSpace on 2018-11-26T17:10:36Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-01-01 We evaluated lateral pterygoid muscle volume in closed and open mouth positions in association with anterior disc displacement, effusion and abnormal articular disc shape from three-dimensional reformations of MRI. A total of 24 MRI of a sample (15 females, 9 males) aged 19-64 years (37.2 years +/- 11.4) were assessed. Segmentation and volumetric assessment of the total, upper and lower heads of the lateral pterygoid muscle were performed using free software. The upper head of the lateral pterygoid muscle had a smaller volume than the lower head at both sides, in the closed- and open-mouth positions. In the open-mouth position, individuals with a subdivided upper head, where one component was inserted in the articular disc and another in the mandibular head, displayed a significantly larger volume of the upper head compared to individuals who had a single attachment to the articular disc (p = 0.0130). The lateral pterygoid muscle has different volumes in the closed-and open-mouth positions. Gender affected muscle volume, specifically the upper head component. Insertion type in the upper head also seemed to affect muscle volume. (C) 2016 Elsevier GmbH. All rights reserved.

Objective The present study aimed to evaluate the precision of the torque applied by 0.022" self-ligating brackets of different brands, the precision of parallelism between the inner walls of their slots, and precision of their slot height. Eighty brackets for upper central incisors of eight trademarked models were selected: Abzil, GAC, American Orthodontics, Morelli, Orthometric, Ormco, Forestadent, and Ortho Organizers. Images of the brackets were obtained using a scanning electron microscope (SEM) and these were measured using the AutoCAD 2011 software. The tolerance parameters stated in the ISO 27020 standard were used as references. The results showed that only the Orthometric, Morelli, and Ormco groups showed results inconsistent with the ISO standard. Regarding the parallelism of the internal walls of the slots, most of the models studied had results in line with the ISO prescription, except the Morelli group. In assessing bracket slot height, only the Forestadent, GAC, American Orthodontics, and Ormco groups presented results in accordance with the ISO standard. The GAC, Forestadent, and American Orthodontics groups did not differ in relation to the three factors of the ISO 27020 standard. Great variability of results is observed in relation to all the variables.

The sphenoid sinus is the most inaccessible part of the face, being inside the sphenoid bone and closely related to numerous vital neural and vascular structures. The objective of this study was to analyze and evaluate the variation of anatomy and the volume of the sphenoid sinus using helical computed tomography and medical imaging software. A total of 47 helical CT scans of sinuses of male and female individuals aged 18–86 years were selected. The images were formatted using ITK-SNAP software, consisting of three steps: (1) segmentation; (2) volumetric analysis and (3) 3D reconstruction. The sphenoid sinuses were also classified according to Hammer, i.e., in conchal, pre-sellar, sellar and post-sellar types. A single investigator, who is specialist in dental radiology and was trained and calibrated, performed the volume and image analysis. After 15 days, the segmentations were repeated. The Dunn’s multiple comparison test revealed significant differences in the volume rankings between the right and left sides (P = 0.0002), with the post-sellar type presenting the greatest volume on the right side compared to pre-sellar and sellar types. In the left sphenoid sinuses, the post-sellar type showed the greatest volume. The Lin’s correlation coefficient showed excellent reproducibility values. According to the applied methodology, it was found that the volume of the sphenoid sinus was influenced by neither age nor gender (P > 0.005). There was difference in the volumes of sphenoid sinus on the right and left sides and in the anatomical classification.

Aim The purpose of this study was to evaluate the dentoskeletal and soft tissue effects resulting from treatment with Klammt's elastic open activator (EOA) functional orthopedic appliance in patients with Class II malocclusion characterized by mandibular deficiency. Materials and methods Teleradiographs were evaluated in the lateral aspect of the initial (T1) and final (T2) orthopedic phases for 16 patients with Class II, Division 1 malocclusion. The age range was from 9 to 11.2 years, with a mean age of 9.9 years. The cephalometric points were demarcated, and cephalometric measurements were obtained by the same investigator to avoid interobserver variability. Results The EOA promoted increased lower anterior facial height (LAFH), increased effective mandibular length, clockwise rotation of the mandible, retrusion and verticalization of the upper incisors, proclination and protrusion of the lower incisors, extrusion of the upper molars, mesial movement of the lower molars and anterior projection of the lower lip. Conclusion Skeletal changes characterized by an increase in mandibular length and dentoalveolar changes with an emphasis on the verticalization and retrusion of the upper incisors, proclination of the lower incisors and mesial positioning of the lower molars were key to improving the occlusal relationship and esthetic facial factors. Clinical significance The EOA is well indicated in patients with Class II malocclusion due to mandibular deficiency with increased overbite, proclined upper incisors and verticalized lower incisors.

The aim of this study was to evaluate and compare changes in linear distance and inclination of lower incisors and canines and intercanine distance after a 30 months orthodontic treatment with self-ligating appliances. Seven patients were treated orthodontically with a Roth prescription passive self-ligating bracket. To perform the measurements and comparisons, CBCT scans were taken before the start of the orthodontic treatment (T(1)) and after a period of 30 months treatment (T(2)). The following measurements were performed: (1) the lower incisors and canines inclination in relation to the mandibular plane, (2) intercanine linear distance in millimeters and (3) linear distance in millimeters of the incisal and apical part of lower anterior teeth to a plane (POGM) passing through pogonion point and perpendicular to the mandibular plane. No significant difference were observed between T(1) and T(2) for canine inclination (p = 0.835), incisors inclination (p = 0.149), canine incisal distance to POGM (p = 0.423) and incisors incisal distance to POGM (p = 0.966), however canine apical distance (p = 0.049) and incisors apical distance (p = 0.002) to POGM was lower at T(1) than at T(2). The intercanine distance was significantly lower (p = 0.022) at T(1) when compared to T(2.) The use of passive self-ligating brackets in orthodontic treatment to solve 4 mm tooth crowding were able to produce dental arch expansion by bodily tooth movement.

Background Clinical cases involving agenesis of all four maxillary incisors are rare, with no previous reports in the literature. Case report The present case report describes an orthodontic treatment combined with esthetic dentistry in a 10-year-old girl with agenesis of all four permanent maxillary incisors, anterior crossbite, permanence of deciduous maxillary canines and transmigration of permanent maxillary canines into the region of the maxillary central incisors. For this case, it was decided on space closure using a fixed orthodontic apparatus and reshaping of the first premolars transforming them into canines. Porcelain veneers were used on the permanent and deciduous canines, substituting the maxillary central and lateral incisors, respectively. Regarding outcome, there was an improvement in facial profile, correction of the anterior crossbite, satisfactory intercuspidation of the teeth and significant esthetic improvement in smile. Maintaining the patient´s natural dentition also kept the bone plate intact for future placement of implants to substitute maxillary deciduous canines at the appropriate age. Conclusions Interdisciplinary planning combining orthodontics and esthetic dentistry was key in resolving this case. Key words:Tooth agenesis, upper incisors, orthodontic treatment.

Este artigo pretende refletir a respeito da educação inclusiva com crianças psicóticas e autistas, utilizandoo referencial freudiano-lacaniano, a partir da reflexão sobre o “Programa Educação Inclusiva: direito à diversidade”. Criado pelo governo em 2003, o objetivo do projeto é a escolarização de alunos com necessidades educacionais especiais nas escolas e classes comuns da rede regular de ensino. Para que essas crianças se beneficiem do programa, são necessárias reformulações na escola para que, de fato, se possa incluir quem está excluído, questionando o ideário político-pedagógico – reformulações que exigem mudanças não apenas no espaço físico e nos conteúdos programáticos, mas um redimensionamento na preparação do professor, ou seja, mudanças referentes à organização e ajuste constante do agenciamento simbólico, com a finalidade de tornar possível uma ação do coletivo.Isto é, para que se possa realizar esse tratamento do Outro, toda a equipe, composta por diferentes áreas, deve ser parceira na construção clínica. Assim, a partir da proposta de Tratamento do Outro, busca-se explorar certas possibilidades, particularmente a de colocar no lugar outra Alteridade que seja alternativa ao Outro primordial do sujeito. Enfim, trata-se de questionar se essas crianças têmestrutura suficiente para usufruir daquilo que o convívio social pode proporcionar-lhes e se a escola reconhece a criança menos sob a ótica de suas capacidades cognitivas do que na sua condição de sujeito do desejo, possibilitando assim que elas se beneficiem das contribuições que o laço social proporciona, considerando-as como sujeitos do desejo, para que então seja possível ver o aluno emsua subjetividade

Purpose: To evaluate the effects of mesenchymal stem cells on liver regeneration in rats following a 70% hepatectomy. Methods: Forty rats were subjected to 70% hepatectomy and then ~106 mesenchymal stem cells (test group), or saline solution (control group), were infused into their livers via the portal vein. Each treatment group was divided into early and late subgroups (euthanized 3 d and 5 d following the operation, respectively). Group comparisons of Albumin, aminotransaminases (AST, ALT), and Alcaline Phosphatase (AP) levels, proliferative index (ki-67+ straining), and mitotic cell counts were conducted. Results: No significant differences in liver regeneration rate, number of mitoses, proliferative index, or serum levels of albumin, AST, or AP were observed. ALT levels were higher in the test group than in the control group (p

MÉTODOS: foram utilizadas telerradiografias em norma lateral de 40 pacientes, divididos em 2 grupos pareados por idade e sexo. O Grupo Anquilose foi constituído de 20 pacientes (10 meninos e 10 meninas) tratados com anquilose induzida e que apresentavam as idades médias inicial e final, respectivamente, de 7a 4m e 8a 3m, e o tempo médio de tração reversa de 11 meses. O Grupo Controle, composto de 20 pacientes (10 meninos e 10 meninas) tratados sem anquilose induzida e que apresentavam as idades médias inicial de 7a 8m e final de 8a 7m, e tempo médio de tração reversa de 11 meses. Foram empregadas as análises de Variância a dois critérios e de Covariância para comparar as variáveis cefalométricas inicial e final e as alterações de tratamento entre os grupos. RESULTADOS: segundo os resultados, as variáveis que evidenciaram as mudanças de tratamento significativas entre os grupos confirmaram que o procedimento de anquilose intencional potencializou a resposta sagital das bases apicais (Pg-NPerp) e aumentou os ângulos de convexidade facial (NAP e ANB). CONCLUSÃO: o protocolo envolvendo a anquilose intencional de caninos decíduos potencializou a resposta sagital das bases apicais. INTRODUCTION: This retrospective cephalometric study analyzed the influence of intentional ankylosis of deciduous canines in patients with Class III malocclusion and anterior crossbite, in the deciduous and early mixed dentition stages, treated by orthopedic maxillary expansion followed by maxillary protraction. METHODS: Lateral cephalograms of 40 patients were used, divided in 2 groups paired for age and gender. The Ankylosis Group was composed of 20 patients (10 boys and 10 girls) treated with induced ankylosis and presenting initial and final mean ages of 7 years 4 months and 8 years 3 months, respectively, with a mean period of maxillary protraction of 11 months. The Control Group comprised 20 patients (10 boys and 10 girls) treated without induced ankylosis, with initial and final mean ages of 7 years 8 months and 8 years 7 months, respectively, with a mean period of maxillary protraction of 11 months. Two-way analysis of variance and covariance analysis were applied to compare the initial and final cephalometric variables and the treatment changes between groups. RESULTS: According to the results, the variables evidencing the significant treatment changes between groups confirmed that the intentional ankylosis enhanced the sagittal response of the apical bases (Pg-NPerp) and increased the facial convexity angles (NAP and ANB). CONCLUSIONS: The protocol involving intentional ankylosis of deciduous canines enhanced the sagittal response of the apical bases. UNIMAR UNESP USP FOB USP UNESP

OBJETIVO: investigar se polimorfismos dos genes que codificam o receptor de progesterona (PROGINS) estão relacionados à ocorrência de aborto espontâneo de repetição (AER). MÉTODOS: em estudo caso-controle, foram selecionados 85 pacientes com antecedente de pelo menos três abortos precoces sem etiologia definida (Grupo Caso) e 157 mulheres com história de pelo menos duas gestações de termo sem intercorrências e sem passado de abortamento (Grupo Controle). Realizada coleta de 10 mL de sangue por punção venosa periférica e extração de DNA pela técnica DTAB/CTAB. As genotipagens foram feitas por reação em cadeia de polimerase (PCR), nas condições de ciclagem específica para o polimorfismo em estudo, seguida de amplificação em gel de agarose a 2%. A visualização das bandas foi feita sob luz ultravioleta e os géis foram fotografados. As diferenças genotípicas e alélicas entre os dois grupos para o polimorfismo PROGINS foram calculadas pelo teste de χ2, adotando-se como nível de significância valores de pPURPOSE: to assess a possible association between polymorphism of the progesterone receptor gene (PROGINS) and recurrent spontaneous abortion (RSA). METHODS: in this case-control study, 85 women with at least three previous spontaneous abortions without an identifiable cause (RSA Group) and 157 women with at least two previous term pregnancies without pathologies and no previous miscarriage (Control Group) were selected. An amount of 10 mL of peripheral blood was collected by venipuncture and genomic DNA was extracted by the DTAB/CTAB method, followed by the polymerase chain reaction (PCR) under specific conditions for this polymorphism and by amplification by 2% agarose gel electrophoresis. The bands were visualized with an ultraviolet light transilluminator and the gels were photographed. Differences in the PROGINS genotype and allele frequencies between groups were analyzed by the χ2 test, with the level of significance set at p

The aim of this study was to evaluate the performance of CBCT three-dimensional (3D) reconstructions and sagittal sections for estimates of cervical vertebrae maturation index (CVMI).The sample consisted of 72 CBCT examinations from patients aged 8-16 years (45 females and 27 males) selected from the archives of two private clinics. Two calibrated observers (kappa scores: ≥0.901) interpreted the CBCT settings twice. Intra- and interobserver agreement for both imaging exhibition modes was analyzed by kappa statistics, which was also used to analyze the agreement between 3D reconstructions and sagittal sections. Correlations between cervical vertebrae maturation estimates and chronological age, as well as between the assessments by 3D reconstructions and sagittal sections, were analyzed using gamma Goodman-Kruskal coefficients (α = 0.05).The kappa scores evidenced almost perfect agreement between the first and second assessments of the cervical vertebrae by 3D reconstructions (0.933-0.983) and sagittal sections (0.983-1.000). Similarly, the agreement between 3D reconstructions and sagittal sections was almost perfect (kappa index: 0.983). In most divergent cases, the difference between 3D reconstructions and sagittal sections was one stage of CVMI. Strongly positive correlations (0.8, p 0.001) were found not only between chronological age and CVMI but also between the estimates by 3D reconstructions and sagittal sections (p 0.001).Although CBCT imaging must not be used exclusively for this purpose, it may be suitable for skeletal maturity assessments.

PURPOSE : To evaluate and compare clinical and inflammatory responses to the surgical trauma caused by cholecystectomy via several access approaches: single-port umbilical incision (SILS), transvaginal natural orifice transluminal endoscopic surgery (NOTES), laparoscopy, and Laparotomy. METHODS : Twenty-eight female pigs were equally divided into four groups and submitted to cholecystectomy by single-port umbilical incision, transvaginal NOTES, laparoscopy, or Laparotomy. An additional five animals served as controls (sham group). Animals were monitored perioperatively regarding anesthesia and surgical procedure times, as well as for the presence of complications. Postoperatively, they were evaluated regarding time to ambulation and feeding, and the presence of clinical events. Procalcitonin, C-reactive protein (CRP), and AQUI feron-gamma (IFN-γ) measurements were performed before surgery and immediately, two days, and seven days after surgery. Animals were sacrificed and necropsied at seven days after surgery. RESULTS : All procedures were successfully performed as proposed in each group. Only minor complications, such as gallbladder perforation and bleeding from the liver bed, were observed during surgery in all groups. The vaginal NOTES group showed higher anesthesia and surgical procedure times compared to the other groups (p

O objetivo deste estudo foi verificar a variação do volume do disco articular da ATM em pacientes com DTM e em indivíduos de controle, correlacionando-a com diagnóstico de imagem de RM e com dados clínicos. Foram analisados 29 exames de ressonância magnética entre pacientes e controles, totalizando 58 ATMs, em cortes sagitais sequenciais das imagens de RM. O software livre MRIcro foi utilizado para delineamento manual dos limites anatômicos do disco articular e obtenção o volume do disco. Para analisar a correlação entre os volumes dos discos e as variáveis clínicas e por imagem, empregou-se o teste de Kruskal-Wallis. Para caracterizar e comparar as variáveis entre gênero e idade foi aplicado o Teste t de Student independente. Observou-se uma correlação entre o deslocamento do disco (p-valor = 0.001 para ATM direita e p-valor = 0.002 para ATM esquerda) e o volume do disco, que aumentou significativamente no grupo de pacientes. Não foi encontrada associação significativa entre gênero e volume dos discos direito e esquerdo (respectivamente; p-valor = 0,640 e 0,390). Concluiu-se que o volume do disco articular aumentou com a presença de desarranjo intra-articular.

Em Ortodontia, a colagem de braquetes é um dos passos mais importantes durante o tratamento, principalmente na técnica Straight Wire, na qual os acessórios possuem uma forma específica para levar cada dente à posição prescrita, no que se refere à inclinação, angulação, ou mesmo adequando a posição vestíbulo-lingual das coroas, que variam devido às suas diferentes espessuras anatômicas. Outro ponto fundamental é a altura na qual os braquetes são posicionados, o que interfere diretamente na oclusão e na estética do sorriso. Se ocorre o posicionamento incorreto dos braquetes, além de contatos prematuros e outros possíveis danos, o profissional despenderá mais tempo realizando dobras compensatórias ou recolagens de acessórios. Assim sendo, o objetivo deste trabalho foi desenvolver e inscrever um projeto de patente, composto por um conjunto de posicionadores de braquetes ortodônticos, no intuito de promover um melhor e mais fácil posicionamento dos braquetes durante a colagem, diminuindo a chance de erros, otimizando o processo e tornando a rotina da clínica ortodôntica mais previsível e eficiente.

Existem várias alterações nos arcos dentários, entre estas se encontram as de número, forma e tamanho dos dentes. O dente supranumerário representa um fator etiológico importante e frequente da má oclusão. Este trabalho teve o objetivo de avaliar a prevalência de dentes supranumerários nos pacientes tratados nos cursos de pós-graduação em Ortodontia da Universidade Cidade de São Paulo. A amostra, composta por 1117 radiografias panorâmicas de pacientes que se submeteram a tratamento ortodôntico corretivo, foi estudada quanto à distribuição da prevalência de dentes supranumerários entre os gêneros, os arcos dentários e as regiões bucais. A média de idade da amostra foi de 13,7 anos, sendo que 56% dos pacientes eram do gênero feminino e 44% do masculino. Do total analisada, apenas 18 pacientes (1,61%) apresentaram dentes supranumerários. Em relação ao gênero, verificou-se uma prevalência de 1,9% no gênero feminino, enquanto o gênero masculino apresentou prevalência de 1,2%. Na comparação entre os gêneros não se verificou diferença com significância estatística. No total foram constatados 24 dentes supranumerários, uma vez que existiram radiografias de pessoas com a presença de mais de um dente supranumerário. Destes 24 dentes, 16 estavam no arco superior e 8 no arco inferior. A partir da metodologia aplicada e dos resultados obtidos, pôde-se concluir que: a prevalência de dentes supranumerários foi de 1,61% dos indivíduos da amostra; não se pôde verificar diferença significante na prevalência de supranumerários entre os gêneros masculino e feminino; e a prevalência de dentes supranumerários foi estatisticamente semelhante para os arcos dentários superior e inferior, apesar de 66,7% deles terem sido localizados no arco superior.

Extreme distal migration of impacted teeth to the subcondylar area and condyle is very rare. Using an interesting sequence of radiographs showing the path of the tooth in the mandible, we describe the intrabony migration of a mandibular second premolar from angle to condyle in a young woman. Cone-beam computed tomography was used to establish the precise location of the tooth.

This paper aims to evaluate results from pancreas-kidney transplants, in type 1 diabetes mellitus patients, comparing the use of Euro-Collins and Belzer or Celsior solutions for organ storage while awaiting transplant. One hundred and twenty two transplants were performed by the same transplant group, between November 2006 and June 2011. All pancreas grafts were perfused during the harvesting process through infusion of the aorta using standard solutions (Belzer or Celsior). Fifty-seven pancreas graft were stored in Euro-Collins solution (EC Group) and sixty six stored with Belzer or Celsior solutions (BC Group). The parameters analyzed were: postoperative complications, graft loss, mortality, hospitalization time and three-month follow-up period. The average cold ischemia time was 15.25 ± 1.98 hours in EC Group and 15.3 ± 2.66 hours in BC Group. The mortality rate was 15.8% in BC Group and 9.2% in EC Group. The loss of graft was 16.9% in EC Group and 8.8% in BC Group. The average hospitalization time was 13.8 days in EC Group and 18.4 days in BC Group. No significant statistical difference was observed in any parameters. It could be concluded that the use of Euro-Collins solution to store pancreas could be used without compromising the outcome of transplants.

Introduction The purpose of this research was to study the influence of soft laser treatment on the process of bone repair after expansion of the midpalatal suture. Methods The sample for this case-control experimental study was 11 dogs. They were randomly divided into 2 groups, both of which underwent rapid maxillary expansion with a hyrax appliance. The animals in group 1 were also treated with laser therapy. They were killed, and histologic specimens of the palatal suture were prepared. The Student t test was applied for independent data, and the Mann-Whitney test was used for nonparametric data. Results A significant difference was observed in the quality of the palatal sutures between the animals in groups 1 and 2. The connective tissues of the sutures in the group 1 animals were similar to the original configurations, with more advanced osteogenesis and fibrogenesis, compared with those of group 2. Conclusions Soft laser appears to influence the behavior of the repair process, contributing to suture reorganization and palatal bone osteogenesis during and after expansion.

Os programas de residência médica, em especial na cirurgia, vêm passando por modificações constantes, não só em nosso meio, como internacionalmente. Em virtude da deterioração da valorização e remuneração médica, as expectativas e perfil do médico residente na área cirúrgica vêm mudando. A avaliação das atitudes, experiência durante o treinamento e expectativas profissionais nos residentes é tópico importante. Recentes trabalhos internacionais publicados na área demonstram tal fato. É digno de nota a ausência de trabalhos semelhantes em nosso meio e a raridade em outros países. O presente estudo tem por objetivo avaliar em médicos residentes da área de cirurgia, através de questionário, atitudes, experiências durante o treinamento e expectativas profissionais. Foram aplicados e analisados questionários adaptados e traduzidos para o Português em 50 residentes de ambos os sexos e diferentes anos de residência. Os resultados deste trabalho mostram alta satisfação com a especialidade, porém grande preocupação financeira e opiniões conflitantes quanto ao futuro da especiliadade; Residency programs, especially in surgery, have been undergoing constant changes, not only in our country, but also internationally.

To assess a possible association between polymorphism of the progesterone receptor gene (PROGINS) and recurrent spontaneous abortion (RSA).In this case-control study, 85 women with at least three previous spontaneous abortions without an identifiable cause (RSA Group) and 157 women with at least two previous term pregnancies without pathologies and no previous miscarriage (Control Group) were selected. An amount of 10 mL of peripheral blood was collected by venipuncture and genomic DNA was extracted by the DTAB/CTAB method, followed by the polymerase chain reaction (PCR) under specific conditions for this polymorphism and by amplification by 2% agarose gel electrophoresis. The bands were visualized with an ultraviolet light transilluminator and the gels were photographed. Differences in the PROGINS genotype and allele frequencies between groups were analyzed by the χ² test, with the level of significance set at p0.05. The Odds Ratio (OR) was also used, with 95% confidence intervals 95%CI.PROGINS genotypic frequencies were 72.3% T1T1 and 27.7% T1T2 for the RSA group and 76.4% T1T1, 22.3% T1T2 and 1.3% T2T2 for the control group. There were no differences between groups when the genotype and allele frequencies were analyzed: respectively p=0.48 (OR: 0.8) and p=0.65 (OR: 0.9).Our results suggest that PROGINS polymorphism is not associated with RSA.

Biliary hamartomas are hepatic lesions related to defects in the ductal plate and are part of the spectrum of adult polycystic disease. Microscopically, the lesions are small and consist of irregular bile ducts amidst a fibrous stroma. There are reports on the malignant transformation of biliary hamartomas, particularly on cholangiocarcinoma. Case 1: a 19-year-old woman presented with increased abdominal volume, lumbar pain, jaundice, choluria, cachexia, and progression to hepatic insufficiency. At autopsy, the liver weighed 8850 g and showed a 20.5-cm mass in the right lobe and nodules in the left lobe. Case 2: a 39-year-old man presented with an asymptomatic nodule in the right hepatic lobe. A 6.5-cm liver segment containing a 3.0-cm nodule was excised. Histopathology of both cases revealed hepatocellular carcinoma associated with multiple bile duct hamartomas (von Meyenburg complex). Bile duct hamartoma is generally an incidental finding at laparotomy and autopsy because its course is asymptomatic. The literature has documented its possible progression to malignant neoplasia. However, this relationship has only been established with cholangiocarcinomas. We report herein for the first time on the association of the lesion with hepatocellular carcinoma.

Introduction: The purpose of this study was to evaluate the skeletal and dental changes in patients who underwent distalization of their maxillary molars with pendulum appliances. Methods: The sample consisted of 31 patients (initial mean age, 14.58 years) with Angle Class II molar relationships and all permanent teeth up to the second molars. The maxillary molars were distalized with pendulum appliances for a mean period of 5.87 months. Lateral cephalograms, 45° oblique radiographs, and dental casts were obtained before and after distalization. Changes produced by the pendulum appliance were analyzed with paired t tests. Results: Maxillary first molar distalization accounted for 63.5% of the space opening; mesial movement of the maxillary first premolars contributed 36.5% of the space. The mean space opening on lateral cephalograms was 7.25 mm, and the rate of molar movement was 1.23 mm per month. The mean distalization of the maxillary molars was 4.6 mm, with a mean distal crown tipping of 18.5° The maxillary molars experienced expansion, with a smaller effect on the first molars than on the second molars. The pendulum appliance produced symmetrical expansion, with a rate of 1.04 mm per month on the right and 1.10 mm per month on the left. Conclusions: The pendulum appliance is effective for distalization of the maxillary molars and the establishment of a Class I molar relationship in a relatively short time. However, caution is needed to control collateral effects, including mesial movement of the first premolars and distal tipping of the molar crowns.

Introduction: This prospective clinical study analyzed the distalization of maxillary molars achieved by the pendulum appliance and its effect on the anchorage teeth during and after fixed orthodontic treatment. Methods: Lateral cephalograms of 22 adolescents (15 girls, 7 boys) taken pretreatment, after distalization, after leveling and aligning, and after fixed orthodontic treatment were evaluated. The initial mean age was 14.5 years (SD = 1.80). The mean time for distalization of the maxillary molars was 5.85 months (SD = 1.82), and the total treatment time was 3.61 years (SD = 1.83). Results: The pendulum appliance moved the maxillary molars distally, but with significant distal inclination, protrusion of the anterior teeth, and increase in lower anterior facial height (LAFH) due to the clockwise mandibular rotation. After fixed orthodontic treatment, the maxillary incisors and the maxillary first premolars and first molars were returned to their pretreatment anteroposterior positions. Thus, at postdistalization, there was 2.1 mm of protrusion of the maxillary first molars, despite the anchorage reinforcement (Nance button and cervical headgear worn at night during fixed appliance therapy). However, at the end of treatment, all patients had Class I molar relationships. Conclusions: The pendulum appliance followed by fixed orthodontic treatment corrected the Class II sagittal relationship, especially due to the dentoalveolar changes secondary to the spontaneous mandibular growth in the anterior direction during fixed appliance treatment.

Nessa pesquisa, foram estudados 32 pacientes, 23 do sexo feminino e 9 do masculino, leucodermas, brasileiros, naturais da cidade de Bauru, estado de São Paulo, com idade variando de 11 anos e 6 meses a 17 anos e 9 meses, idade média de 14 anos e 7 meses, portadores de más oclusões de Classe II, 1ª divisão de Angle e presença de todos os dentes permanentes de segundo a segundo molar do lado oposto. Todos os indivíduos selecionados receberam como mecanismo para a distalização dos molares superiores, o aparelho Pendulum de Hilgers, que foi empregado por um período de 5,87 meses. Foram feitas as telerradiografias em norma lateral convencional, lateral de 45º e modelos de estudo, antes e depois das distalizações dos molares superiores. Foram obtidas as medidas cefalométricas e as medidas dos modelos de estudo e as diferenças entre as médias iniciais e finais do experimentos foram submetidas ao teste estatístico de Wilcoxon para dados pareados. Essa avaliação possibilitou verificar as alterações esqueléticas e os efeitos da distalização sobre os molares, pré-molares, caninos e incisivos superiores. Com base nos resultados obtidos e na metodologia empregada, no que tange as alterações esqueléticas e dentárias decorrentes da distalização de primeiros e segundos molares superiores com o aparelho Pendulum, julga-se lícito concluir que a força leve e contínua das molas distalizadoras do aparelho e o intervalo de tempo não alteraram significativamente o posicionamento ânteroposterior da maxila e mandíbula. Observou-se uma taxa de distalização mensal dos molares de 1,06 mm e 1,07 mm, respectivamente para os lados direito e esquerdo. Essa distalização foi acompanhada da inclinação distal das coroas dos molares que acarretou a rotação mandibular no sentido horário, refletindo diretamente no aumento da altura facial ântero-inferior. O efeito recíproco do aparelho Pendulum sobre a unidade de ancoragem acarretou o movimento mesial dos primeiros e segundos pré-molares e dos caninos. Outro efeito negativo constatado foi o movimento vestibular dos incisivos superiores e a sua conseqüência para a alteração no perfil facial. Associado a distalização dos molares superiores foi observado também alterações verticais e transversais em molares, pré-molares e caninos. In this study, 32 patients were studied. 23 females and 9 males, leucoderma, Brazilian, natural from Bauru, São Paulo state, with ages ranging from 11,06 years to 17,09 years, mean age 14,07 years, all carriers of Angle Class II division 1 malocclusions and presence of all permanent teeth from second molar to second molar in the same arch. To all the selected individuals were given for distalization of upper molars, the HILGERS Pendulum appliance which was used for a period of 5,87 months. Lateral cephalometric radiographs, 45º lateral cephalometric radiographs and dental casts were made before and after the upper molars distalizations. The cephalometric and the dental casts measurements were obtained and the differences between the initial and final measurements were submmited to the Wilcoxon statistical test for paired data. This evaluation possibilitated to verify the skeletal alterations and the effects of distalization on upper molars and premolars, canines and incisives. On the basis of the obtained results and on the employed methodology concerning the skeletal and dental alterations caused by the distalization of upper first and second molars with the Pendulum appliance it can be concluded that the light and continued force of the distalization springs and the time spent did not alter significantly the maxila and mandible anteroposterior positioning. A monthly distalization rate of 1,06 mm and 1,07mm was observed, respectively for right and left sides. This distalization was followed by the distal inclination of the molar crown which caused a mandibular rotation in a clockwise direction, reflecting directly on the increase of the anteroinferior facial height. The reciprocal effect of Pendulum appliance over the anchorage unit caused the first and second premolars and canines mesial movement. Another negative effect proved was the vestibular movement of the upper incisives and its consequence on the facial profile alteration. Associated to the upper molar distalization it was also observed the vertical and transverse alterations in molars, premolars and canines.
