ABSTRACT

Este trabalho tem o objetivo de analisar as concepções de maternidade para mulheres inférteis de diferentes níveis socioeconômicos que estão em tratamento de reprodução assistida. Trata-se de um estudo qualitativo, descritivo, que utilizou como instrumento uma entrevista semiestruturada e contemplou temas como o significado de família, desejo/expectativas sobre filho e gestação e expectativas sobre a maternidade. Participaram da pesquisa 48 mulheres inférteis acima de 35 anos que usam tecnologias de reprodução assistida de alta complexidade em instituições privada e pública. Os dados foram tratados pela análise de conteúdo em que emergiram os temas: representações sociais da família; representações sociais da maternidade; expectativas com a gestação e os modelos maternos; e o filho imaginado. As participantes representaram a família de forma positiva, como um sistema de suporte, de fundação e origem de amor, configurando-a como um laço social. Por outro lado, as concepções de família com base na consanguinidade também estiveram presentes, representando a família pela perpetuação da espécie e pela importância do laço biológico. A maternidade foi marcada por significativa idealização, sendo vista como um papel gratificante e de realização da feminilidade. O peso da cobrança social para procriar também foi sentido como um dever a cumprir e que, na impossibilidade de se realizar, gera sentimentos de inferioridade, menos-valia, impotência e inadequação perante a sociedade, o que reforça o estigma da infertilidade. Tais resultados apontam a importância de reflexões sobre o papel da mulher na nossa cultura, visto que a maternidade é ainda utilizada como medida para o sucesso ou fracasso feminino. Faz-se necessário também refletir sobre a possibilidade da maior inserção do trabalho psicológico na reprodução assistida, visto a carga emocional e social envolvidas nesse processo.(AU)


This study aimed to analyze the conceptions of motherhood for infertile women from different socioeconomic levels who are undergoing assisted reproduction treatment. This is a qualitative and descriptive study that used a semi-structured interview as an instrument and included topics such as the meaning of family and desires/expectations about the child, pregnancy, and motherhood. A total of 48 infertile women over 35 years of ages using high-complexity assisted reproductive technologies in private and public institutions participated in this research. The data were treated by content analysis in which the following themes emerged: family social representations; social representations of motherhood; expectations with pregnancy and maternal models; and the imagined son. Participants represented the family in a positive way as a support system and the foundation and origin of love, embracing the family as a social bond. On the other hand, the family concepts based on inbreeding were also present, representing the family by perpetuation of the species and the importance of biological bonds. Motherhood was marked by significant idealization, being seen as a gratifying role and the fulfillment of femininity. The weight of the social demand to procreate was also felt as a duty to be fulfilled that, in the impossibility of carrying it out, generates feelings of inferiority, worthlessness, impotence, and inadequacy toward society, which reinforce the stigma of infertility. Results point to the necessary reflections on the role of women and our culture since Motherhood is still used as a measure of female success or failure. They also point to a reflection on the possibility of greater inclusion of psychological work in assisted reproduction given the emotional and social burden involved in this process.(AU)


Este estudio tuvo como objetivo analizar las concepciones de maternidad de mujeres infértiles, de diferentes niveles socioeconómicos, que se encuentran en tratamiento de reproducción asistida. Se trata de un estudio cualitativo, descriptivo, que utilizó como instrumento una entrevista semiestructurada e incluyó temas como el sentido de la familia, deseos/expectativas sobre el hijo y el embarazo y expectativas sobre la maternidad. Participaron en la investigación un total de 48 mujeres infértiles, mayores de 35 años, usuarias de tecnologías de reproducción asistida de alta complejidad en instituciones públicas y privadas. Los datos se sometieron a análisis de contenido del cual surgieron los temas: representaciones sociales familiares; representaciones sociales de la maternidad; expectativas con el embarazo y modelos maternos; hijo imaginado. Las participantes representaron a la familia de manera positiva, como sistema de apoyo, fundamento y origen del amor, configurándola como vínculo social. Por otro lado, también estuvieron presentes las concepciones familiares basadas en la consanguinidad, representando a la familia para la perpetuación de la especie y la importancia del vínculo biológico. La maternidad estuvo marcada por una importante idealización, vista como un rol gratificante y de realización de la feminidad. También se sintió el peso de la demanda social de procrear como un deber que cumplir y que, ante la imposibilidad de realizarlo, genera sentimientos de inferioridad, desvalorización, impotencia e inadecuación en la sociedad, lo que refuerza el estigma de la infertilidad. Por tanto, son necesarias reflexiones sobre el papel de la mujer en nuestra cultura, ya que la maternidad se sigue utilizando como medida del éxito o fracaso femenino. También se reflexiona sobre la posibilidad de una mayor inclusión del trabajo psicológico en la reproducción asistida dada la carga emocional y social que implica este proceso.(AU)

ABSTRACT

O hospital constitui-se como um contexto em que a urgência subjetiva pode vir a se apresentar de forma frequente, instaurando, para cada sujeito, uma vivência de angústia. O objetivo desta pesquisa foi investigar as possibilidades para uma clínica das urgências subjetivas no contexto de um hospital universitário em Salvador, considerando as vivências em uma residência multiprofissional. Trata-se de uma pesquisa qualitativa de caráter exploratório, em que se realizou revisão teórica sobre o tema e se construiu um caso clínico, sob orientação psicanalítica. A escolha do caso baseou-se na escuta clínica ao longo dos atendimentos e da atuação em equipe multiprofissional, considerando os impasses ao longo do tratamento. Foram utilizados registros documentais produzidos pela psicóloga residente ao longo dos atendimentos, que ocorreram durante três meses. Os resultados apontam para as contribuições da escuta psicanalítica no tratamento das urgências e na atuação em equipe multiprofissional no contexto hospitalar. A subjetivação da urgência permitiu, no caso em questão, um tratamento pela palavra do que havia incidido diretamente no corpo como fenômeno. Conclui-se pela relevância em discutir o tema da urgência e suscitar novas pesquisas, reintroduzindo no contexto hospitalar a questão sobre a subjetividade.(AU)


Hospitals are contexts in which subjective urgency can frequently materialize, triggering an experience of anguish for each subject. Hence, this research investigates the possibilities of establishing a subjective urgency clinic at a university hospital in Salvador, considering the experiences in a multidisciplinary residence. A qualitative, exploratory research was conducted by means of a theoretical review on the topic and construction of a clinical case, under psychoanalytical advisement. The case was chosen based on clinical listening during the sessions and performance in a multidisciplinary team, considering the obstacles for long-term treatment. Data were collected from documentary records produced by the resident psychologist during three months. Results point to the contributions of psychoanalytic listening to treating subjective urgencies and to the performance of a multidisciplinary team in the hospital context. In the case in question, subjectivation of urgency allowed a treatment through the word of affecting phenomenon. In conclusion, discussing urgency and conducting further research, are fundamental to reintroduce subjectivity in the hospital context.(AU)


El hospital es un contexto en el que frecuentemente se puede percibir una urgencia subjetiva, estableciendo una experiencia de angustia para cada sujeto. El objetivo de esta investigación fue investigar las posibilidades de una clínica de urgencia subjetiva en el contexto de un hospital universitario en Salvador (Brasil), considerando las experiencias en una Residencia Multiprofesional. Se trata de una investigación cualitativa, de carácter exploratorio, en la que se realizó una revisión teórica sobre el tema y construcción de un caso clínico, con orientación psicoanalítica. La elección del caso se basó en la escucha clínica a lo largo de las sesiones y actuación en un equipo multidisciplinar, considerando los impasses para el tratamiento a largo plazo. Se utilizaron registros documentales elaborados por el psicólogo residente, durante las atenciones, que se realizaron durante tres meses. Los resultados apuntan a las contribuciones de la escucha psicoanalítica en el tratamiento de urgencias y en la actuación de un equipo multidisciplinario en el contexto hospitalario. La subjetivación de la urgencia permitió, en el caso en cuestión, un tratamiento a través de la palabra de lo que había afectado directamente al cuerpo como fenómeno. Se concluye que es relevante discutir el tema de la urgencia y plantear nuevas investigaciones, reintroduciendo el tema de la subjetividad en el contexto hospitalario.(AU)

ABSTRACT

Abstract In this study, the manufacturing process of lamivudine (3TC) and zidovudine (AZT) tablets (150+300 mg respectively) was evaluated using statistical process control (SPC) tools. These medicines are manufactured by the Fundação para o Remédio Popular "Chopin Tavares de Lima" (FURP) laboratory, and are distributed free of charge to patients infected with HIV by the Ministry of Health DST/AIDS national program. Data of 529 batches manufactured from 2012 to 2015 were collected. The critical quality attributes of weight variation, uniformity of dosage units, and dissolution were evaluated. Process stability was assessed using control charts, and the capability indices Cp, Cpk, Pp, and Ppk (process capability; process capability adjusted for non-centered distribution; potential or global capability of the process; and potential process capability adjusted for non-centered distribution, respectively) were evaluated. 3TC dissolution data from 2013 revealed a non-centered process and lack of consistency compared to the other years, showing Cpk and Ppk lower than 1.0 and the chance of failure of 2,483 in 1,000,000 tablets. Dissolution data from 2015 showed process improvement, revealed by Cpk and Ppk equal to 2.19 and 1.99, respectively. Overall, the control charts and capability indices showed the variability of the process and special causes. Additionally, it was possible to point out the opportunities for process changes, which are fundamental for understanding and supporting a continuous improvement environment.

ABSTRACT

OBJECTIVE@#To compare the prevalence of chromosomal aneuploidies and pregnancy outcomes of D5 and D6 blastocysts subjected to preimplantation genetic testing for aneuploidy (PGT-A).@*METHODS@#Clinical and laboratory data of 268 couples who underwent PGT-A at the Reproductive Center of the First Affiliated Hospital of Zhengzhou University from September 2018 to September 2020 were collected. The prevalence of chromosomal aneuploidies and pregnancy outcomes of D5/D6 biopsied blastocysts were compared.@*RESULTS@#Compared with D6 blastocysts, the euploidy rate of D5 blastocysts was significantly higher (49.1% vs. 41.1%, P = 0.001 1), whilst their aneuploidy rate was significantly lower (50.9% vs. 58.9%, P = 0.001 1). The rate of numerical abnormalities of D6 blastocysts was significantly higher than that of D5 blastocysts (27.9% vs. 20.2%, P = 0.000 5). For patients under 35 years old, the euploidy rate of D5 blastocysts was significantly higher than that of D6 blastocysts (53.8% vs. 44.3%, P = 0.001), whilst the numerical abnormality rate was significantly lower (16.3% vs. 23.9%, P = 0.001). For both D5 and D6 blastocysts, the euploidy rates for patients <= 35 were significantly higher than those for > 35. The elder group had the lowest rates for aneuploidies and live births. Compared with those receiving D6 blastocysts transplantation, the pregnancy rate, implantation rate and live birth rate for those receiving thawed D5 blastocysts transplantation were significantly higher (60.2% vs.37.0%, P = 0.000 3; 59.1% vs.37.0%, P = 0.000 6; 47.7% vs. 28.3%, P = 0.002).@*CONCLUSION@#For patients undergoing PGT-A, the chromosomal euploidy rate for D5 blastocysts is higher than that for D6 blastocysts, and the clinical outcome of D5 blastocysts with normal signal is better than that of D6 blastocysts. Elder patients have a higher rate of aneuploidies.

ABSTRACT

Objective: To characterize the serum bile acid profiles of healthy children in Zhejiang Province. Methods: A cross-sectional study was conducted on 245 healthy children who underwent imaging and laboratory biochemical tests during routine physical examinations at the Children's Hospital of Zhejiang University School of Medicine from January 2020 to July 2022. Overnight fasting venous blood samples were collected, and the concentrations of 18 individual bile acids in the serum were accurately quantitated using tandem mass spectrometry. The concentration difference of bile acid were compared between different genders and to explore the correlation between age and bile acid levels. Used the Mann-Whitney U test for intergroup comparison and Spearman test to correlation analysis. Results: A total of 245 health children with a age of 10 (8, 12) years including 125 boys and 120 girls. There were no significant differences in levels of total bile acids, primary and secondary bile acids, free and conjugated bile acids between the two gender groups (all P>0.05). The serum concentrations of ursodeoxycholic acid and glycoursodeoxycholic acid in girls were significantly higher than those in boys (199.0 (66.9, 276.5) vs. 154.7 (49.3, 205.0) nmol/L, 274.0 (64.8, 308.0) vs. 181.0 (43.8, 209.3) nmol/L, Z=2.06, 2.71, both P<0.05). The serum taurolithocholic acid in both boys and girls were positively correlated with age (r=0.31, 0.32, both P<0.05). The serum chenodeoxycholic acid and glycochenodeoxycholic acid in the boys group were positively correlated with age (r=0.20, 0.23, both P<0.05), whereas the serum tauroursodeoxycholic acid in the girls group was negatively correlated with age (r=-0.27, P<0.05), and the serum cholic acid was positively correlated with age (r=0.34, P<0.05). Conclusions: The total bile acid levels are relatively stable in healthy children in Zhejiang province. However, individual bile acids showed gender differences and were correlated with age.

ABSTRACT

Abstract Development of insecticides resistance mainly hinge with managements techniques for the control of Jassid, Amrasca biguttutla biguttutla. Five insecticides were applied against field collected and laboratory rared jassid populations during the years of 2017 to 2019 to profile their resistance level against field population of jassid through leaf dip method. Very low resistance level was found in jassid against confidor whereas high level of resistance was observed by pyriproxyfen against other test insecticides. Gradual resistance was observed against diafenthiuron. It is concluded that for the management of Jassid repetition of same insecticide should be avoided. The use of confidor may be reduced to overcome resistance against Jassid.


Resumo Desenvolvimento da resistência a inseticidas principalmente em dobradiça com técnicas de manejo para o controle de jassid, Amrasca biguttutla biguttutla. Cinco inseticidas foram aplicados contra populações de jassídeos coletados em campo e em laboratório durante os anos de 2017 a 2019 para traçar o perfil de seu nível de resistência contra populações de jassídeos em campo através do método de imersão nas folhas. Nível de resistência muito baixo foi encontrado em jassid contra confidor, enquanto alto nível de resistência foi observado por piriproxifeno contra outros inseticidas de teste. Resistência gradual foi observada contra o diafenthiuron. Conclui-se que, para o manejo do jassid, a repetição do mesmo inseticida deve ser evitada. O uso de confidor pode ser reduzido para superar a resistência contra jassid.

ABSTRACT

Abstract Behavioral lab bioassays involving termites must be promptly performed to allow intended observations prior to death from dissecation, typical of these soft-bodied insects. To this end, topic markers have been proposed as an alternative to histological stains which, while not always toxic are inevitably lengthy to apply. Among recommended topic markers, gouache is easy to apply, dries out quickly, but it is known affect termites in the long run, being suitable only to short-term bioassays. Its alternative, colored glue, is also easy to apply, but it takes long to dry and it is too dense and heavy, being thus prone to affect termite walking patterns. Here we tested a mix of gouache and colored glue aiming to combine the qualities of both into a suitable topical marker for Cornitermes cumulans termites. Similar patterns of survival presented by marked and unmarked termites ruled out concerns about toxicity of this mixture. Such results were consistent across distinct group densities evidencing that the mixture does not interfere with, nor it is affected by, crowding effects. Because crowding regulates interindividual interactions and these underlie most behaviors, the mixture can be thought to be suitable to behavioral studies. We argue that this 1:2 glue:gouache mixture is an excellent alternative to mark termites for lab bioassays. Being atoxic, cheap, easy to apply, and non-invasive, this mixture may happen to be useful not only for termites but also in bioassaying other similarly soft-bodied insects.


Resumo Bioensaios comportamentais em laboratório com cupins devem ser realizados rapidamente a fim de garantir observações antes da morte por dissecação, típico desses insetos de corpo mole. Para este fim, marcadores tópicos têm sido propostos como uma alternativa para marcadores histológicos que, embora nem sempre tóxico, possuem uma aplicação demorada. Entre os marcadores tópicos recomendados, tinta guache é de fácil aplicação, rápida secagem, porém afeta os cupins em bioensaios longos, sendo adequado apenas para bioensaios curtos. Sua alternativa, cola colorida, também é de fácil aplicação mas leva muito tempo para secar e é muito denso e pesado, afetando os padrões de caminhamento dos cupins. No presente estudo, nós testamos uma mistura de tinta guache e cola colorida objetivando combinar as qualidades de ambos os marcadores tópicos em um marcador tópico adequado para Cornitermes cumulans. Padrões similares de sobrevivência entre cupins marcados e controle indicam a ausência de toxicidade na mistura de tinta guache e cola colorida. Tais resultados são consistentes em grupos de densidades distintas, o que comprova que a mistura não interfere, nem sofre efeitos de aglomeração. Uma vez que a aglomeração regula as interações inter-individuais e afetam a maioria dos comportamentos, a mistura pode ser adequada para estudos comportamentais. Nós argumentamos que a mistura de tinta guache e cola (1:2) é uma excelente alternativa como marcador tópico em cupins para bioensaios em laboratório. Sendo atóxico, barato, fácil de aplicar e não invasivo, esta mistura pode ser útil não só para os cupins, mas também em bioensaios com outros insetos de corpo mole.

ABSTRACT

La disponibilidad de cepas bacteriana para el estudio de la resistencia bacteriana es clave para los avances en la investigación básica y clínica respecto del tema. Existen pocos biorrepositorios o bancos de bacterias con mecanismos de resistencia conocidos, aisladas de infecciones clínicamente significativas. Una revisión de la literatura revela que sólo en los Estados Unidos de América existe un biobanco de aislados resistentes disponibles para estudios. En esta publicación se cuenta cómo se creó el primer biorrepositorio de bacterias resistentes en Chile asociados a la Red de Laboratorios MICROB-R, con la participación de 11 centros distribuidos a lo largo del país, que a la fecha cuenta con más de 3.500 aislados bacterianos estudiados fenotípica y genotípicamente, disponibles para la comunidad científica chilena.


The availability of bacterial strains for the study of bacterial resistance is key to advances in basic and clinical research. There are few biobanks of bacteria with known resistance mechanisms, isolated from clinically significant infections. A review of the literature reveals that only in the United States of America is there a biobank of resistant isolates. This publication shows the creation of the first biorepository of resistant bacteria Chile associated with the MICROB-R Laboratory Network, with the participation of 11 centers distributed throughout the country, which to date has more than 3,500 bacterial isolates studied phenotypically and genotypically, available to the Chilean scientific community.

ABSTRACT

Com o fim de propiciar um ambiente que possibilite decisões ágeis, criativas e efetivas no sistema de saúde, o Laboratório de Inovações no SUS do Ceará (FeliciLab) tem adotado o uso de métodos inovadores de gestão de projetos. Este relato de experiência tem como objetivo apresentar como a Escola de Saúde Pública do Ceará (ESP/CE) conseguiu, através do FeliciLab, orquestrar um conjunto de pessoas, métodos e tecnologias capazes de provocar uma quebra em padrões até então apresentados no mercado de tecnologias direcionadas para o sistema de saúde, diante da crise sanitária ocasionada pela pandemia de covid-19. Com adoção de metodologias mais ágeis de condução de trabalho e gerenciamento de crises, ampliou-se a percepção de valor da tecnologia da informação (TI) da ESP/CE, nutrida pela compreensão de que inovar é mais do que produzir e implantar tecnologias: trata-se de transformar os modos de criar e consumir soluções, de forma a impactar os contextos e as experiências das pessoas.


In order to provide an environment with agile, creative, and effective decisions in the health system, the Felicilab laboratory has been adopting the use of innovative project management methods. This experience report aims to present how the Escola de Saúde Pública do Ceará (ESP/CE), Brazil, had managed to orchestrate, through FeliciLab, a set of people, methods, and technologies from a disruptive perspective of standards hitherto presented in the market of technologies directed to the health system, in face of the health crisis caused by the covid-19 pandemic. With the adoption of more agile methodologies for conducting work and managing crisis, the perception of the value of the Information technology (IT) used at ESP/CE was expanded, understanding that innovating is more than producing and implementing technologies: it means transforming the ways of creating and consume solutions in order to impact on personal experiences and their context.

ABSTRACT

Resumen El objetivo del estudio fue comparar la extracción de ADN de quistes de Acanthamoeba sp. con un método disponible comercialmente y cuatro no comerciales utilizando tratamiento térmico y ultrasonido para la amplificación por una reacción en cadena de la polimerasa (PCR) convencional, reduciendo tiempos de preparación y extracción de las muestras, como una herramienta para el diagnóstico en el laboratorio clínico. Se utilizó una cepa de Acanthamoeba, genotipo T4, cultivada en agar no nutritivo. Los quistes para analizar, en tres períodos de enquistamiento, se almacenaron a temperatura ambiente. Se extrajo ADN mediante cinco métodos: pretratamiento térmico, ultrasonido y combinaciones de ellos. La PCR se llevó a cabo utilizando cebadores específicos JDP1/JDP2. La concentración y pureza del ADN extraído con los protocolos evaluados revelaron diferencias estadísticamente significativas (p<0,0001). El método E (comercial), el A (térmico) y el B (ultrasonido) lograron los mejores rendimientos en la amplificación del fragmento específico de Acanthamoeba sp. por la PCR convencional.


Abstract The objective of the study was to compare the DNA extraction of Acanthamoeba sp. cysts with a commercially available method and four non-commercial ones, with heat and ultrasound treatment that allows amplification by conventional polymerase chain reaction (PCR), reducing sample preparation and extraction times, such as a tool for diagnosis in the clinical laboratory. To this aim, a strain of Acanthamoeba T4 grown on non-nutrient agar was used. Plates with cysts at three different encystation times were stored at room temperature until the study was carried out. DNA was extracted with five methods that included pretreatments (thermal and ultrasound) or combinations of them. PCR was performed using specific primers JDP1/JDP2. Concentration and purity of DNA revealed statistically significant differences (p<0.0001) between methods. Method E (commercial), method A (thermal) and B (ultrasound) got the best yields in amplifying the specific fragment of Acanthamoeba sp. by conventional PCR.


Resumo O objetivo do estudo foi comparar a extração de DNA de cistos de Acanthamoeba sp. com um método comercialmente disponível e quatro não comerciais utilizando tratamento térmico e ultrassom para amplificação por reação em cadeia da polimerase (PCR) convencional, reduzindo os tempos de preparo e extração das amostras, como ferramenta para o diagnóstico no laboratório clínico. Foi utilizada uma cepa de Acanthamoeba, genótipo T4, cultivada em ágar não nutritivo. Os cistos para analisar foram armazenados em temperatura ambiente, correspondendo a três períodos de encistamento. O DNA foi extraído por cinco métodos: pré-tratamento térmico, ultrassom e combinações deles. A PCR foi realizada usando iniciadores específicos JDP1/JDP2. A concentração e a pureza do DNA extraído com os protocolos avaliados revelaram diferenças estatisticamente significativas (p<0,0001). Os métodos E (comercial), A (térmico) e B (ultrassom) alcançaram os melhores rendimentos na amplificação do fragmento específico de Acanthamoeba sp. por PCR convencional.

ABSTRACT

Resumen El monóxido de carbono (CO) es un gas producido principalmente por combustión incompleta de hidrocarburos. La intoxicación por exposición ambiental puede presentarse con síntomas inespecíficos y constituye la causa más importante de aumento de carboxihemoglobina (COHb). Su nivel en sangre depende de la duración de la exposición, la ventilación minuto y las concentraciones de CO y oxígeno en el ambiente. La elevada toxicidad radica en la hipoxia tisular que se genera. Se presenta el caso de un paciente masculino, 73 años, en seguimiento en el hospital por neumonía intersticial no específica como patología de base. En un control de laboratorio se encontró 11,9% de COHb, sin exposición a tabaco. No utilizaba calefacción a gas sino un panel cerámico eléctrico, recientemente pintado con esmalte sintético. La suspensión del uso del panel normalizó la COHb. El CO, producto de descomposición térmica del esmalte sintético, explica la causa de la intoxicación.


Abstract Carbon monoxide (CO) is a gas produced mainly by incomplete combustion of hydrocarbons. Poisoning from environmental exposure can present with nonspecific symptoms and is the most important cause of increased carboxyhemoglobin (COHb). Its blood level depends on the duration of exposure, minute ventilation, and the concentrations of CO and oxygen in the environment. The high toxicity lies in the tissue hypoxia that is generated. The case of a male patient, 73 years old, under follow-up in the hospital for non-specific interstitial pneumonia as the underlying pathology was presented. In a laboratory control, COHb 11,9% was found. There was no exposure to tobacco and there was no use of gas heating but of an electric ceramic panel, recently painted with synthetic enamel type paint. The suspension of the use of the panel normalised the COHb. The CO product of thermal decomposition of synthetic enamel explains the cause of poisoning.


Resumo O monóxido de carbono (CO) é um gás produzido principalmente pela combustão incompleta de hidrocarbonetos. A intoxicação por exposição ambiental pode se apresentar com sintomas inespecíficos e é a causa mais importante de aumento da carboxihemoglobina (COHb). Seu nível em sangue depende do tempo de exposição, da ventilação minuto e das concentrações de CO e oxigênio no ambiente. A alta toxicidade está na hipóxia tecidual gerada. Apresentamos o caso de um paciente do sexo masculino, 73 anos, em acompanhamento hospitalar por pneumonia intersticial inespecífica como patologia de bas. Em um controle laboratorial, achou-se 11,9% de COHb, sem exposição ao tabaco. Não utilizava aquecimento a gás e sim um painel elétrico cerâmico, recentemente pintado com esmalte sintético. A suspensão do uso do painel normalizou o COHb. O CO produto da decomposição térmica do esmalte sintético explica a causa da intoxicação.

ABSTRACT

La celulitis orbitaria representa una causa frecuente de inflamación de la órbita, constituyendo una urgencia médica que requiere un manejo multidisciplinario. Se presenta caso de una recién nacida con clínica de aumento de volumen en región bipalpebral derecha y fiebre de 24 horas de evolución. Al examen físico se evidencia proptosis de ojo derecho, aumento de volumen bipalpebral que impide la apertura del globo ocular en su totalidad con signos de flogosis y secreción purulenta en borde palpebral. Los laboratorios reportan leucocitosis y trombocitosis reactiva; tomografía de orbita muestra tumefacción y edema periorbitario derecho, aumento difuso de densidad grasa post-septal extra e intraconal, hallazgos sugestivos de celulitis orbitaria derecha. Se indica antibioticoterapia con vancomicina y cefotaxime, ameritando además drenaje de absceso, obteniéndose secreción purulenta, en la que se aísla Estafilococo aureus meticilino resistente. Siendo una patología inusual en este grupo etario, se recomienda la publicación de este caso(AU)


Orbital cellulitis represents a frequent cause of inflammation of the orbit, constituting a medical emergency that requires multidisciplinary management. We present a case of a newborn with clinic of volume increase in right bipalpebral region and fever of 24 hours of evolution. Physical examination reveals proptosis of right eye, increase of bipalpebral volume that prevents the opening of the eyeball in its entirety with signs of flushing and purulent eyelid margin secretion. Laboratories report leukocytosis and reactive thrombosis; orbital tomography scan shows right periorbital swelling and edema, diffuse increase of extra and intraconal post-septal fat density, suggestive findings of right orbital cellulitis, covered with vancomycin and cefotaxime; subsequently requires abscess drainage where Staphylococcus aureus methycilin- resistant is isolated. Being an unusual pathology in this age group, the publication of this case is recommended(AU)
