Factors associated with increased atrial septum thickness in infants with left heart hypoplasia syndrome
Authors: Carvalho Bárbara Justo , Ayello Vera Demarchi
Published: October 2019

Introduction: Hypoplastic Left Heart Syndrome (HLHS) encompasses a spectrum of cardiac malformations characterized by underdevelopment of the left heart structures and aorta that, despite the low incidence among cases of congenital heart disease have high mortality rates. Phenotypic variations of the anomaly may influence the success of the interventional and surgical procedures, especially the characteristics related to the atrial septum and foramen ovale (FO), in cases where balloon catheter septostomy is necessary to maintain the interatrial shunt.Objectives: To analyze the gross features of the atrial septum of hearts with HLHS in order to define and guide therapeutic procedures on this structure, correlating them with other morphological alterations of the syndrome, such as the anatomy of the heart valves. Methods: We studied 18 hearts of patients diagnosed and deceased with HLHS, all belonging to the anatomic collection of the Laboratory of Pathology of the Heart Institute (InCor) HCFMUSP. The atrial septum was evaluated for FO patency and size, as well as for the presence of bulging of its lamina to one or the other atrial cavity. Other morphological features of the anatomical specimen such as atresia or patency of the mitral valve and caliber of the ascending aorta and pulmonary trunk were annotated. After resection of the atrial septum, histological sections were made for microscopic measurements of the maximum and minimum thickness of the lamina (atrial septum).Results: The mean age of the patients was 34.5 days (57% male), with a mean atrial septal thickness of 1.90 mm (0.63-4.09 mm). The mean diameter of the pulmonary trunk and aorta were 1.16 cm and 0.22 cm, respectively. FO was patent in 39% of cases (mean diameter 4,4 mm, range 4 to 8 mm), with bulging of the lamina to one of the atrial cavities in half of the cases. The mitral valve was atretic in 21% of the specimens. There was a significant difference in the mean thickness of the atrial septum in cases with patent versus closed FO, being thicker in cases where the FO was closed (p = 0.047). The ratio FO/age presented a statistically significant negative correlation with the atrial septum thickness (r = -0.76 and p <0.05).Discussion and Conclusions: The results indicate that the patency and size of the oval foramen may influence the thickness of the atrial septum, suggesting that this factor may limit the success of therapeutic interventions, especially balloon catheter septostomy.

Introduction: Obsessive-compulsive disorder (OCD) is a common, chronic and long-lasting mental disorder. The current first-line therapy for OCD is high doses of selective serotonin reuptake inhibitor (SSRI) and cognitive-behavioral psychotherapy. For patients with refractory symptoms, studies demonstrated that they may respond well to Deep Brain Stimulation (DBS), a technique that can modulate altered neuronal activity. Some stimulation sites are currently being used as targets to DBS and showed good response, but further analyses are necessary to improve the location of the electrodes since some patients demonstrated a poor outcome. Neuroimaging that assess white matter such as diffusion tensor image and tractography can evaluate the quality of the targets and assess the tracts that are affected by the electric field of the electrodes used in the surgery. Our hypothesis is that the patient outcome depends on the trajectory of the tracts that are affected by the electric field.Objectives: Our aim is to investigate which tracts connected with the stimulation sites contribute to clinical improvement effects and weather is possible to predict the outcomes based on connectivity.Methodology: We analyzed 4 patients (2 female) with treatment-refractory obsessive-compulsive disorder undergoing deep brain stimulation targeting the anterior limb of the internal capsule/ nucleus accumbens (ALIC). We will perform tractography analysis of the fibers using the volume of active tissue (VTA) as the region of interest. We will relate the alteration in OCD symptom severity on Yale-Brown obsessive-compulsive scale (Y-BOCS) between the condition before surgery and one-year follow-up with the tracts involved with the stimulation sites using DTI data such as fractal anisotropy and mean diffusivity.Partial Results: Half of the patients did show great improvement and the other two maintained a bad outcome. We found that active stimulation of the ALIC more lateral and posterior of the nucleus was associated with a better outcome. Currently, the description of the tracts involved in patients with better outcomes is performed. The tracts involved with this result will be determined by analysis of DTI and tractography.Discussion and Conclusion: For a future perspective, the results will be important to improve the stimulation sites in DBS surgery resulting in better outcomes.
Non epileptogenic Rasmussen`s encephalitis: a case report
Authors: Murakami Junior Mario Minor , Baron Gabriel Bernardes , Gutierre Marcela Usberti , Guimarães Filho Leandro José , Rodrigues Júlia Chartouni
Published: October 2019

Rasmussen's encephalitis (RE) is a very rare chronic inflammatory unilateral encephalopathy with still unknown etiology. It predominantly affects children under the age of 10, but can also affect adolescents and adults. Current evidence on possible etiologies are divided in two main theories. The first one is based on brain inflammation caused by a reaction to a foreign antigen. The second one is based on an autoimmune disease that is limited to a single hemisphere of the brain. The common presentation is intractable and frequent focal motor seizures, often associated with progressive neurological decline, and progressive unilateral focal cortical atrophy. Progression of the inflammatory process in MRI is considered a good biomarker in RE.
Objectives: Report a rare case of a female infant presenting atypical manifestations of uncommon symptoms without seizures caused by Rasmussen's encephalitis.
Case Report: A ten-year-old right-handed female presented to the emergency department with sudden onset of abnormal involuntary movements of the right upper and lower limbs, face paresia of the same side and loss of attention without loss of consciousness. The involuntary contractions were brief, random, irregular, and worsened with activity, along with a positive milkmaid grip sign. She also displayed reduced movement speed and hyperactive biceps, triceps, patellar and ankle jerk reflexes. Associated with the motor abnormalities, the girl presented with a recent but progressive decrease in cognitive functions, which caused a decline in school performance and impaired reasoning, and affective blunting. She had no sign of previous neuropsychomotor development abnormality. She was taken to a quaternary hospital where a MRI and a CT of the brain were performed. MRI showed atrophy of the left cerebral hemisphere, predominantly in the operculum and head of the caudate nucleus, hypersignal in the insular cortex and adjacent white matter. CT presented with hypoattenuation of the left frontal lobe and parieto-occipital white matter associated with atrophy of the head of the caudate nucleus of the same side and enlargement of the adjacent fissures and sulcus. A subsequent PET-CT showed a left cerebral hemisphere hypometabolism, predominantly in the basal ganglia, temporal, frontal and insular lobes. Functional evaluation detected diffuse unilateral disorganization of brain electric activity, but no epileptic paroxysmal discharges were found on the electroencephalogram. After hospitalization, human immunoglobulin at the dose 2g/kg/day was used for five days. The girl remained stable, with no complications. After sixteen days, she was discharged with a rehabilitation program and follow-up care.

Published: October 2019

Introduction: The learning takes place, mainly, by the integration of new knowledge acquired to previously existing ones, that is, by the elaboration of new information, in any of its previously analyzed forms. In the Problem Based Learning (PBL) method, constructivism is obtained at the expense of activation of prior knowledge, elaboration of new information, establishment of goals for self-directed study, and increament in the complexity of semantic networks in the final discussion of problem solving. Quality of life (QoL) can be considered as a subject of multiple approaches, contextualizations and applicability of which is used by several areas of knowledge. All the components that make up the quality of life can be measured and evaluated using quantitative instruments, including questionnaires, the main one being the WHOQOL-Bref, developed by the WHO, for having a cross-cultural evaluation methodology that allows uniform results. Objectives: To analyze in a global way the quality of life of medical students who work in the PBL model of the University of Ribeirão Preto (UNAERP). Methodology: A total of 90 students from the UNAERP medical school, aged over 18, enrolled in the 1st, 6th and 11th stages were included in this study. After signing the TCLE approved by the local CEP, the students answered a questionnaire based on the WHOQOL-bref. Results: A total of 55.5% of the women and 44.5% of the men with a mean age varying according to the stages (20 years, 1st stage, 22 years, 6th stage and 26 years in the 11th stage) were evaluated. When analyzing the degree of satisfaction of the students with regard to the PBL methodology, a percentage of 49.1% satisfaction was observed at the beginning of the course (1st stage), followed by 65.4% in the 6th stage and 77% at the end of the course (11th stage). The student’s satisfaction with the ability to perform the activities of his day-to-day recorded that in the first stage, 21.2% can carry out their activities with adequacy; in stage 6, 34.5% and in stage 11, 69.8% feel satisfied or very satisfied in this analysis. Students also had increased satisfaction with their academic performance when compared to the beginning and end of the course; on the other hand, in the intermediate phase, a percentage decrease can be observed as can be observed in the first stage: 42.8%; 6th stage: 33.5%; 11: 77%. Discussion and conclusions of the results: In this study, we measured the quality of life of university students of medicine at UNAERP and then made them reflect on how they deal with their personal, physical, social and mental issues throughout their training course. The PBL methodology enhances the need for independent study and focuses on student-led learning and improvement, which allows the student to evolve with a progressive improvement in the ability to perform day-to-day tasks and academic performance.
Morfofunctional changes caused by viral agents associated with teratogenicity, inflammatory biomarcators and arboviroses
Authors: Moraes Leonardo Bruno Fonseca , Macedo Aloisio Afonso Avelar
Published: October 2019

Introduction: In the second half of the 20th century, many anomalous effects and individuals were examined, arousing concern in the medical community at the time.The rubella syndrome in the 1930s showed that the placenta was not a barrier for all exogenous agents. In 2015 an increase in the prevalence of microcephaly cases has been reported in twenty times in Brazil, and this malformation is associated with the vertical transmission of the Zika virus (ZIKV) by the Ministry of Health. Based on these data, ZIKV-related microcephaly as well as other comorbidities associated with arboviruses have been discussed in several scientific events. Therefore, it is not yet known exactly how the ZIKV can cause microcephaly. To date, there are still controversial results on (1) the risk of spontaneous abortion and teratogenesis induced by treatment with intereferon (inflammatory biomarker) with the development of diseases caused by arbovirosis; (2) the profile of the inflammatory response to arvoviroses. Objectives: Evaluate inflammatory biomarkers and morphofunctional changes caused by viral agents associated with teratogenicity. Methods and Procedures: For the accomplishment of this scientific article, a bibliographical review was used consulting the information bases like SciELO, Pubmed, base LILACs, Periódicos CAPES and CNPq and Annals of Scientific Initiation and Research of the University of Ribeirão Preto. Results: Studies show that in the active phase of viral replication in pregnant women with positive serology for Zika virus, for example, increased IL-2, IL-4, IL-9, IL-12, IL-13, IL-17 and IFN -gamma. In contrast, IL-23 did not change at the same stage. The relationship between elevation of IL-4, IL-10, MCP-1, TNF-ALFA, TNF-beta and MCP-1 in the amniotic fluid of pregnant women correlated with Autistic Spectrum Disorder was also enhanced. As for the findings on biological materials from animals immunodeficiated with the Zika virus, was observed that the trophoblasts were able to reduce the replication of the viral agent and the transfer time in the placental barrier. Conclusions: Inflammatory biomarkers have a great relationship and potential for detection of teratogenic events. As for the blocking ability of viral replication, it is observed that placental precursor cells slow the transfer of the viral to the fetus, but does not prevent.

Published: October 2019

The purpose of this study was to compare postoperative evolution of insulin sensibility in diabetic patients after the two most relevant bariatric surgeries nowadays, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). A retrospective cohort study was conducted with type 2 diabetic patients, who underwent RYGB or SG from 2013 to 2018. The laboratory and anthropometric data was analyzed pre-surgery and during a 2-year follow-up. The tool chosen for this comparison was the HOMA2 nonlinear equations, calculated from fasting glycemia and blood insulin. The two surgical procedures were compared. There was significant difference between both evolutions in the first 6-months follow-up (p=0.029), but no difference was presented at the 1-year (p=0.053) or at the 2-year follow-up (p>0.05). Therefore, there was no long-term difference between surgeries, which fuels discussions about their mechanisms of action and their relevance in the treatment of insulin resistance.

Published: October 2019

The cardiovascular disease is the main cause of mortality in the western population and the Peripheral Arterial Disease (PAD) evolves, in large proportion, to the amputation of the affected limb. This study aimed to synthesize blood vessels using scaffolds of rabbit’s Inferior Vena Cava (IVC) and test its interaction with the receiver tissue and test inflammatory responses. Methods: The IVC were obtained from 8 rabbits to decellularization or in natura veins. The descellularized veins (DV) were obtained through protocols of decellularization established previously, using sodium dodecyl sulfate 1% (SDS) and mechanical agitation for 2 hours.12 animals were used to the experiment in vivo (3 animals in each group), being the product implanted in the interescapular dorsal area of each animal. The established groups are: Group 1- in natura allogeneic vein; Group 2- DV-SDS no cells added; Group 3- DV- SDS with 1x105 adipose tissue allogeneic Mesenchymal Stem Cells (MSC) added; Group 4- DV-SDS + autologous MSC. The (MSC) of the autologous receptors were collected 21 days before the implant and expanded in vitro. The explants were analyzed by histomorphological/immunohistochemistry and the peripheral blood was collected in the pre operatory in 1d, 7d, 14d, 30d and 60 day post operatory to dose the inflammatory and anti-inflammatory interleukins. Results: IL-10 and PDGF levels were significantly higher in group 4, which also showed neovascularization and large endothelial reconstruction. We may conclude the existence of an inflammatory response to the use of allogeneic grafts, which is lower when associated with autologous MSC.

Nitric oxide in patients with chronic chagas disease
Authors: Faria Victor Antonio Costa , Estabile Bruno Lepera
Published: October 2019

Among the main causes of death around the world, we can highlight those caused by cardiovascular diseases, which have been growing significantly. The knowledge of the pathophysiology of cardiovascular diseases evidences the involvement of inflammatory processes, acute or chronic, with action of pro-inflammatory and vasoactive factors. One of these factors is nitric oxide (NO), a potent vasodilator that acts on the physiological regulation of vascular tone and has its serum levels altered in the presence of cardiovascular event, representing a physiological compensatory mechanism, to be included in Chagas disease.
Method: Peripheral blood samples from 2 patients (men, mean age 65 years) with positive Chagas; disease serology (cardiac form, chronic phase) were collected at the cardiology outpatient service of the Hospital Electro Bonini (UNAERP). Two healthy volunteer participants were used as a negative control. NO (NO 2- / NO 3-) levels were determined by a quantitative detection kit for nitrate and nitrite concentrations using colorimetric assay. Absorbance was read at 540 nm.
Partial Results: The median NO activity was 1.4 umol/L in chagasic patients and 1.0 umol/L in healthy participants (p <0.001).
Discussion and conclusion of the results: The cardiac form of Chagas Disease, a condition caused by the chronic infection of the protozoan Trypanossoma cruzi and marked by chronic inflammation and progressive myocardial cell damage, has progressed with new endemic areas throughout the world, although its incidence has decreased last years. The parasite compromises the energetic synthesis of cardiac myocytes without altering the mitochondrial ultrastructure. It is reported that the parasite can control the central structure of the organelle in order to obtain substrate for its proliferation. Therefore, it has become relevant to investigate the relationship of serum NO concentration with cardiovascular diseases, due to the importance of vasoactive factor and the subject for public health. Developing knowledge that allows better understanding of oxidative stress in the presence of T. cruzi infection and associating them with inflammatory mechanisms culminates in the elucidation of this chronic pathology.
Anatomia normal da radiografia de tórax
Authors: Wada Danilo Tadao , Rodrigues José Antonio Hiesinger , Santos Marcel Koenigkam
Published: October 2019

A radiografia simples do tórax permite identificar um conjunto de estruturas e órgãos, incluindo os elementos da parede torácica (ossos e partes moles), cavidades pleurais, vias aéreas, hilos pulmonares, vasculatura pulmonar, mediastino, coração, aorta e pulmões direito e esquerdo. Este artigo visa abordar as principais representações das estruturas anatômicas contempladas pela radiografia de tórax através de um texto programado com exemplos e ilustrações baseadas em exames de nosso serviço. Inicialmente, é preciso atentar para a técnica, características do paciente e variantes anatômicas. É importante identificar as regiões das mamas, a bolha gástrica e a opacificação infradiafragmática direita pelo fígado. Da parte óssea, avaliamos principalmente as clavículas, região dos ombros, arcos costais, coluna torácica e o esterno. Os seios costofrênicos representam o principal marcador de doença da cavidade pleural. Devemos avaliar a via aérea central (principalmente traqueia e carina), os hilos pulmonares direito e esquerdo e a vasculatura pulmonar.  É importante conhecer as estruturas que formam a silhueta cardiomediastinal normal, para assim poder identificar a presença de lesões mediastinais e sinais de doença cardiovascular. Já em relação à anatomia pulmonar, devemos lembrar que o pulmão direito é diferente do esquerdo e avaliação das imagens em PA e perfil é importante para localizar mais adequadamente as alterações radiográficas nos pulmões. Por último, mas não menos importante, devemos conhecer as principais variantes anatômicas identificadas no RX de tórax, com por exemplo a costela cervical, as calcificações costocondrais e o lobo acessório da veia ázigos.

Published: October 2019

É muito importante que sejam seguidos o roteiro de análise (semiologia) e a linguagem (terminologia) corretos na identificação, interpretação e descrição dos achados em exames de imagem, inclusive na radiografia simples (RX) de tórax. O consenso na terminologia é importante também para facilitar a comunicação entre os médicos das diferentes especialidades e entre os diferentes profissionais que atuam na área de saúde, além de uniformizar a avaliação e comparação de resultados no campo da pesquisa e investigação científica. Neste texto, descrevemos o consenso atual dos termos descritivos a serem utilizados na avaliação do exame de RX do tórax, incluindo as alterações com aumento da atenuação pulmonar (por ex.: opacidades alveolares e intersticiais), redução da atenuação pulmonar (por ex.: cistos, bolhas e cavidades) e alterações extrapulmonares (por ex.: obliteração do seio costofrênico, alargamento mediastinal).

Reconhecer os principais sinais radiológicos nos exames de tórax pode auxiliar na identificação dos padrões de doenças e estreitar o diagnóstico diferencial. Muitos sinais utilizam termos metafóricos e alguns são descritos até como altamente sugestivos de um diagnóstico. Alguns sinais podem ser vistos tanto na radiografia quanto na tomografia, enquanto outros apenas em um ou outro método. Juntamente com a semiologia radiológica correta e o uso adequado da terminologia, o conhecimento dos sinais radiológicos favorece a interpretação mais correta das alterações nos exames de imagem do tórax. Nesse artigo, realizamos uma breve revisão ilustrativa dos principais sinais descritos na radiografia do tórax.

Estudo do processo de transmissão de Grande sertão: veredas, de Guimarães Rosa, em livros didáticos de língua portuguesa
Authors: Barreto Josenilce Rodrigues de Oliveira , Santiago-Almeida Manoel Mourivaldo
Published: October 2019

Temos por objetivo realizar, neste trabalho, uma investigação acerca do processo de transmissão que o texto Grande sertão: veredas (1967), de Guimarães Rosa, percorreu até chegar, como produto final, às mãos dos alunos e professores da educação básica, através dos Livros Didáticos de Língua Portuguesa  - LDLPs. Para isso, coletamos treze LDLPs, dos quais apenas seis apresentaram menção ou fragmentos do referido texto. Partindo desse corpus, realizamos o cotejo entre os fragmentos encontrados de Grande sertão: veredas nos LDLPs e o texto-base, este definido como a quinta edição da referida obra, publicada em 1967, ainda em vida do autor. A partir do cotejo, detectamos algumas mutilações textuais no que tange à adição, omissão, alteração ou substituição de pontuação, palavras, frases ou trechos inteiros, o que pode prejudicar o entendimento e o conhecimento do próprio texto, já que muitos estudantes têm acesso a muitos textos literários somente a partir de tais materiais didáticos. Feitas essas considerações, destacamos que, para a realização deste trabalho, amparamo-nos nos preceitos teórico-metodológicos, principalmente, de Blecua (1983), Cambraia (2005), Spaggiari e Perugi (2004) e Spina (1994), que versam sobre o labor do crítico textual, bem como sobre o processo de transmissão de textos literários.
Cotejo entre variantes gráficas em manuscritos goianos dos séculos XVIII e XIX
Authors: Felício Carolina Faleiros , Xavier Vanessa Regina Duarte
Published: October 2019

A Filologia nos permite, através de critérios adequados, editar manuscritos antigos, conservando, em sua transcrição, o máximo possível, suas formas originais, o que possibilita, dentre vários estudos, o de caráter ortográfico. O corpus desta pesquisa é composto por quarenta cartas goianas redigidas entre os anos de 1751 e 1752, cujas edições fac-similar e semidiplomática estão disponíveis em Xavier (2012). Também faz parte do corpus a edição semidiplomática de um processo de partilha e inventário de bens de Catalão-Go, de 1851, a qual encontra-se em Pires (2015). O objetivo da pesquisa foi analisar variações gráficas presentes nos documentos referidos, comparando-as com as grafias presentes em instrumentos normatizadores da escrita da época, como os dicionários de Bluteau (1712-1728) e de Moraes Silva (1813), a fim de averiguar a consonância ou não entre elas. Primeiramente, foram coletados todos os vocábulos com variações gráficas, a saber, vocálicas e consonantais. Após a coleta, suas grafias foram verificadas nos dicionários mencionados e, em seguida, o mesmo foi feito com suas etimologias nos dicionários de Machado (1977) e Cunha (1986). Por fim, realizou-se a análise quantitativa e qualitativa das variantes, com base em obras de autores como Coutinho (1976), Williams (1975) e Teyssier (1997).
Tipologia das obras lexicográficas e o léxico histórico do Português Brasileiro
Authors: Cunha Claudio de Assis da , Aguilera Vanderci De Andrade
Published: October 2019

A tarefa de definir os diferentes tipos de obras lexicográficas não é fácil. A diferença, por exemplo, entre dicionário, léxico, tesouro, vocabulário ou glossário não é consensual entre os estudiosos da matéria. Alguns metalexicógrafos se baseiam em critérios linguísticos para estabelecer sua tipologia, outros na história da lexicografia, outros, ainda, em trabalhos lexicográficos já existentes. A convergência de seus métodos está no fato de que quase todos se valem de dicotomias para postular suas definições. Diante do exposto, o presente artigo busca: (i) trazer à luz as particularidades de cinco tipos de obras lexicográficas, a saber: dicionário, léxico, tesouro, vocabulário e glossário, com o objetivo de colaborar para o reconhecimento das especificidades de cada uma dessas tipologias e (ii) discutir o status de uma obra lexicográfica realizada sobre manuscritos dos períodos colonial e imperial do Brasil.
Terminologia da Radiação Solar: elaboração de um glossário bilíngue (português-francês)
Authors: Bastianello Renata Tonini , Zavaglia Adriana
Published: October 2019

O presente artigo visa a descrever o processo de elaboração de um glossário bilíngue (português-francês) de termos da Radiação Solar, apresentando a compilação de um corpus de estudo especializado, a coleta de termos, a comparação de traços descritores na busca por equivalências e a redação da micro e macroestrutura. A terminologia da Radiação Solar – subárea da Energia Solar Fotovoltaica – se caracteriza como multidisciplinar: possui termos próprios e termos emprestados de outros campos do conhecimento. Identificar essas unidades terminológicas e buscar seus equivalentes em outros idiomas para fins terminográficos são tarefas necessárias para auxiliar profissionais e aprendizes da área, assim como tradutores de documentos técnicos, pois, com o uso cada vez mais difundido da Energia Solar Fotovoltaica, a tradução de livros e manuais técnicos, contratos e propagandas – que trazem consigo termos da Radiação Solar, começam a fazer parte da realidade do tradutor. Para este estudo, nos baseamos nos conceitos da Teoria Comunicativa da Terminologia (CABRÉ, 1999), utilizamos as ferramentas da Linguística de Corpus, através do AntConc (ANTHONY, 2014) e empregamos o método dos Ganchos Terminológicos (DUBUC, 1985) para a busca por relações de sinonímia e equivalência.

Published: October 2019

Objetivo: Relatar e discutir o tratamento realizado para solucionar o problema estético decorrente da alteração cromática do incisivo central superior esquerdo (21), tratado endodonticamente e com restauração insatisfatória de resina composta. Relato do caso: Agentes clareadores à base de perborato de sódio e/ou peróxido de hidrogênio foram utilizados em técnicas intra e extracoronária, imediata e mediata. Após as sessões de clareamento dentário, o resultado obtido não foi satisfatório frente aos anseios do paciente, fato que justificou a substituição da restauração em resina composta com recobrimento da face vestibular (faceta direta). Conclusão: Considerando os resultados clínicos obtidos, pôde-se concluir que o clareamento dentário, embora conservador às estruturas dentárias, não foi efetivo à resolução do problema decorrente da alteração cromática. Por sua vez, o desgaste da face vestibular e posterior restauração direta com resina composta, embora menos conservador, foi satisfatório para solucionar o problema estético e se mostra efetivo após dois anos de controle clínico.

Background: Peripheral Dual-energy X-ray absorptiometry (DXA) can be applied to identify low bone mineral density (BMD) patients, however, DXA is not sufficiently available in many countries. Thus, the use of simpler and cheaper screening tools than DXA to detect low BMD become indispensable. Objectives: The objective of this study was to correlate São Paulo osteoporosis risk index (Sapori) and mandibular cortical index (MCI) screening tools with the femur DXA results of patients in our sample of Brazilian women. A secondary objective was to assess which of these screening tools better correlates with the results of the Frax tool. Material and Methods: Exams of women who had undergone panoramic radiographic examination at the beginning of dental treatment and peripheral DXA for screening osteoporosis from 2010 to 2014 were included. The MCI was evaluated, and Sapori and Frax were calculated with their available online software tools. Spearman correlation was performed to analyse the level of correlation between femur T-scores (and MCI and Sapori values, as well to perform the level of correlation between Frax and MCI and Sapori values. Results: The spearman correlation comparing the numerical T-score values and the categorical values of MCI (rs=-0.274), and of Sapori (rs=-0.470), showed a statistically significant inverse correlation for both equations (p<0.01). The Spearman equation comparing the values obtained with Frax and MCI did not show a statistically signifcant correlation (p>0.01). But the equation comparing the values obtained with Frax and Sapori showed a positive, moderate and statistically significant correlation between them (rs=0.460). Conclusion: MCI is not a reliable screening tool to identify women with low BMD or Osteoporosis, whereas more optimistic results were observed for the Sapori.

Infrared thermography is a functional examination that can document physiological changes such as abnormal cutaneous vasomotor activity in inflammatory and neurogenic pictures related to nociceptive and neuropathic pain by mapping the thermal distribution on the surface of the skin. Objective: The aim of this study was to verify if there is a facial thermal difference between the symptomatic and asymptomatic group for myogenic TMD according to the Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD) in a European population sample. Material and methods: Sixty-one subjects between 20 and 40 years (26.2 ± 7.6 years) of both sexes were divided into two groups. The 28 facial thermo-anatomic points were selected and the values of minimum (Tmin), mean (Tmed) and maximum (Tmax) temperatures, average of hemiface temperatures of whole sample, temperature difference (ΔT(°C)) between groups and from these data an algorithm was formulated to separate the groups with greater accuracy. Results: There was an average difference of 0.3 °C of all points when comparing the two groups. The symptomatic group had lower maximum temperature for frontal and lateral views when compared to the asymptomatic group (p<0.05), and presented lower average temperature in frontal view (p<0.05). Symptomatic individuals for myogenic TMD presented a reduction of facial cutaneous blood flow corresponding to lower maximum temperature by the proposed method of analysis of thermal anatomical points. Conclusions: Infrared thermography showed potential to be a screening and complementary diagnostic examination method for patients with myogenic temporomandibular disorders in the daily clinic just by frontal face image.

Authors: KITAZAWA CHISATO , YAMANAKA AKIRA

The pigment cells of some sea urchin embryos emanate autofluorescence in response to light irradiation. However, it is unclear if this feature is maintained throughout larval development. In the present study we observed embryos and larvae of the temnopleurid sea urchins Temnopleurus hardwickii, T. reevesii, T. toreumaticus and Mespilia globulus exposed to light irradiation, and compared our findings with those of a strongylocentroid, Hemicentrotus pulcherrimus. After exposure to ultraviolet irradiation for a few minutes, there was a strong signal from the temnopleurid sea urchins. The signal was detected from a cell mass that is part of the adult (juvenile) rudiment, formed during development of the prism to the two-armed larval stage and not from pigment cells. This signal was observed in both live and formalin-fixed specimens. Fluorescence was also detected from the digestive organs, coelomic pouches, the ciliary band on the oral hood, from some yellowish-green cells and ectodermal cells, although there were some differences among species. In live H. pulcherrimus larvae, the amniotic cavity that is part of the adult rudiment emanated autofluorescence in response to ultraviolet irradiation. These results indicate that the autofluorescence observed in the cell mass of temnopleurid sea urchins is caused by a different mechanism than previously described. This feature may be a useful marker to trace development of the cell mass.

Microfossils in the form of wheels are characteristic of Holothuroidea and Ophiocistioidea (Echinodermata). Only a few wheel fossils have been ever reported without detailed description from Japan. Five wheel fossils were collected from the Carboniferous part of the Omi Limestone distributed in Itoigawa City, Niigata Prefecture, central Japan. The Limestone is included in the Akiyoshi Terrane generated by accretion of seamounts in the trench area. These wheels were identified as Protocaudina botoni (Gutschick, 1959) (Ophiocistioidea, Rotasacciidae) and Thalattocanthus consonus Carini, 1962 (Holothuroidea, Synaptida, Theeliidae). The diagnosis of the genus Protocaudina Croneis, 1932 has been revised to cover all current valid species. The Limestone was deposited as a reef carbonate on a pelagic, shallow-water seamount suggesting that these species habitats were distributed in the pelagic environments.
First report of the mitrate Lagynocystis (Echinodermata: Stylophora) in the Ordovician of the Baltic paleobasin

Three incomplete thecae of the stylophoran Lagynocystis cf. pyramidalis (Barrande, 1887) are described from the Upper Ordovician of the Baltic Paleobasin for the first time. These specimens of Lagynocystis are the first records of this genus from the Ordovician outside peri-Gondwana, thus significantly expanding its paleogeographical distribution of this genus. Due to the preservation of the specimens the microstructure of the stereom is studied for the first time in this genus.

Fifty-eight echinoid species from 22 families in nine orders were collected from middle and southern Japan. One species, Aeropsis fulva, is reported here for the first time from Japan, and four species, Mespilia levituberculata, Pseudoboletia maculata, Lissodiadema purpureum and Echinodiscus tenuissimus require systematic re-examination.
Two partial mitochondrial gene sequences (COI and 12S-rRNA) suggested that Ceramaster japonicus (Sladen, 1889) and Ceramaster patagonicus (Sladen, 1889) (Asteroidea: Goniasteridae) from the Japanese waters are probably of the same species

Our recent morphological studies on the echinoderm collection of the National Museum of Nature and Science, Tokyo (NMST), indicated that the goniasterid starfishes Ceramaster japonicus (Sladen, 1889) and Ceramaster patagonicus (Sladen, 1889) are distributed in the Pacific Oceanside of Japan. In this study, we studied the NMST samples of C. japonicus and C. patagonicus from Japan, by using two mitochondrial DNA genes, the COI and 12S-rRNA, as markers to test relationships between these species in Japan. C. patagonicus sequences from GenBank were mined and included in the analyses. Results of phylogenetic and haplotype network analyses of both genes (final sequence lengths: COI = 317 bp, 12S = 477 bp) suggested that "Ceramaster patagonicus" and "Ceramaster japonicus" from Japanese waters are almost certainly synonymous without any population structure inside Japan.

First finding of brittle star Ophiocnemis marmorata in jellyfishes of genus Rhopilema in waters of Vietnam is described.      Symbiosis between scyphomedusae and epizoic invertebrates, in particular with hyperiid amphipods, has long been known (Thiel 1976). However, the association of echinoderms with jellyfish is unusual and has seldom been reported.      Russian investigators worked in the Nhatrang Bay near the Tam Island in 2011. Underwater they could meet enough greater number Scyphozoa jellyfishes Rhopilema hispidum (Vanhöffen, 1888).      Inside of a bell of many jellyfishes were visible brittle stars. One such jellyfish was placed in a bucket under water and delivered aboard a vessel together with all symbionts. Among symbionts there were 9 juvenile fishes, 7 swimming crabs Charybdis feriata (Linnaeus, 1758), 4 shrimps and 5 brittle star specimens Ophiocnemis marmorata (Lamarck, 1816).
Comparison of 2D SEM imaging with 3D micro-tomographic imaging for phylogenetic inference in brittle stars (Echinodermata: Ophiuroidea)

Recent efforts to reconstruct the phylogeny of brittle stars (ophiuroids) have shown the need for more objective and reproducible data collection methods than the traditional visual examination and verbal description of morphological characters. Complex skeletal structures may be better understood in three dimensions than in two dimensions obtained from techniques like scanning electron microscopy (SEM). We test this hypothesis using three types of three-dimensional tomographic imaging methods—lab-based micro-CT, X-ray microscopy and synchrotron-based tomography—to examine the morphology of ophiuroid arms, and compare them with two-dimensional data obtained from SEM. We describe the advantages and disadvantages of each instrument and set of parameters in terms of the ease and efficiency of data collection for morphometric analyses. We present new morphological observations obtained by digital sectioning of three-dimensional images that could not be achieved with SEM. Overall, our findings suggest that three-dimensional imaging has a high potential to address the gaps in knowledge of the internal ophiuroid skeleton, which will be pivotal to providing morphological characters that will aid in phylogenetic reconstructions.
A geometric morphometric analysis of Arachnoides placenta (Echinoidea: Clypeasteroida): An examination of ontogenetic development and morphological variation

Authors: SWISHER ROBERT E. , LIN JIH-PAI
Published: October 2019

Irregular echinoids, particularly clypeasteroids or “sand dollars”, have obtained highly adaptive morphologies suited to their life habitats. Specimens (n = 26) of a clypeasteroid echinoid Arachnoides placenta were examined to understand how these adaptive morphologies were ontogenetically and developmentally obtained. Ontogenetically, early post-larval juvenile specimens have a pentagonal morphologic outline (known as ambitus) that shifts to a circular or a sub-circular morphology observed in the largest adult specimens. Circular morphology appears optimized for the adult life habitat or niche. Both landmark and semilandmark geometric morphometric methodologies were applied to quantify shape change, ontogenetic variation, and developmental morphology in A. placenta. Ambitus change is concentrated along the interambulacral regions with broader curvature variations occurring across both ambulacral and interambulacral regions. Circular adult morphology was a result of non-isometric shape change concentrated anteriorly with minor variation around posterior margin/periproctal furrow. Interior morphologic change of the petaloids and periproct was also quantified, mainly impacting posterior outline morphology. Minimal deformation of the basicoronal plates was detected, indicating stability during ontogeny. Results indicated that complex, non-isometric allometric shape change, both along the ambitus and interiorly, is required to morph from a pentagonal outline in post-larval juveniles to a circular or sub-circular ambitus morphology in adults. This analysis demonstrates the advantages of both landmark and semilandmark geometric morphometric analyses for quantifying developmental change and shape variation in Clypeasteroida.
Combined visualization of echinoderm hard and soft parts using contrast-enhanced micro-computed tomography

Authors: ZIEGLER ALEXANDER
Published: October 2019

Recent studies have shown that micro-computed tomography (µCT) must be considered one of the most suitable techniques for the non-invasive, three-dimensional (3D) visualization of metazoan hard parts. In addition, µCT can also be used to visualize soft part anatomy non-destructively and in 3D. In order to achieve soft tissue contrast using µCT based on X-ray attenuation, fixed specimens must be immersed in staining solutions that include heavy metals such as silver (Ag), molybdenum (Mo), osmium (Os), lead (Pb), or tungsten (W). However, while contrast-enhancement has been successfully applied to specimens pertaining to various higher metazoan taxa, echinoderms have thus far not been analyzed using this approach. In order to demonstrate that this group of marine invertebrates is suitable for contrast-enhanced µCT as well, the present study provides results from an application of this technique to representative species from all five extant higher echinoderm taxa. To achieve soft part contrast, freshly fixed and museum specimens were immersed in an ethanol solution containing phosphotungstic acid and then scanned using a high-resolution desktop µCT system. The acquired datasets show that the combined visualization of echinoderm soft and hard parts can be readily accomplished using contrast-enhanced µCT in all extant echinoderm taxa. The results are compared with µCT data obtained using unstained specimens, with conventional histological sections, and with data previously acquired using magnetic resonance imaging, a technique known to provide excellent soft tissue contrast despite certain limitations. The suitability for 3D visualization and modeling of datasets gathered using contrast-enhanced µCT is illustrated and applications of this novel approach in echinoderm research are discussed.
