Taller de concordancia en la evaluación de imágenes capilaroscópicas / Reliability of nailfold videocapillaroscopy workshop

Introducción: la capilaroscopia es un método no invasivo que permite observar la microvasculatura en el área periungueal. Los resultados informados pueden ser altamente variables entre distintos observadores. A lo largo del tiempo surgieron métodos cuantitativos y semicuantitativos para mejorar la reproducibilidad. Objetivos: conocer el nivel de acuerdo intra e interobservador al informar los diferentes patrones capilaroscópicos en individuos con diferente nivel de entrenamiento. Materiales y métodos: estudio de corte transversal. Participaron médicos reumatólogos especialistas y en formación que habían realizado previamente un curso virtual de capacitación en capilaroscopia. Recibieron 40 imágenes capilaroscópicas proyectadas en una presentación de PowerPoint y debían responder a través de un cuestionario digital. Se evaluó la concordancia de respuestas intra e interobservador. Resultados: se encontró un alto nivel de concordancia global con un kappa 0,66 IC 95% (0,63-0,70) p<0,0000. También en otros grupos como reumatólogos en formación: kappa 0,65 IC 95% (0,60-0,71) p=0,0000, y médicos reumatólogos: kappa 0,67 IC 95% (0,62-0,72) p=0,0000. Conclusiones: el nivel de concordancia encontrado fue globalmente alto, independientemente del nivel de entrenamiento de los profesionales, y de ser o no reumatólogo. La concordancia fue superior cuando se comparó a quienes tenían más de 4 años de experiencia en la realización de videocapilaroscopia.

Introduction: videoapillaroscopy is a non-invasive method that allows the observation of the microvasculature in the periungual area. Reported results can be highly variable between different observers. Over time, quantitative and semi-quantitative methods emerged to improve reproducibility. Objetives: to know the level of intra and interobserver agreement when reporting the different capillaroscopic patterns in individuals with different levels of training. Materials and methods: cross section study. Specialist rheumatologists and those in training who had previously completed a virtual capillaroscopy training course participated. They received 40 capillaroscopic images projected in a PowerPoint presentation and had to issue their response through a digital questionnaire. Concordance of intra and interobserver responses was evaluated. Results: a high level of global agreement was found with a kappa 0.66 CI 95% (0.63-0.70) p<0.0000, also in other groups such as rheumatologists in training: kappa 0.65 CI 95% (0.60-0.71) p=0.0000, physicians rheumatologists: kappa 0.67 95% CI (0.62-0.72) p=0.0000. Conclusions: the level of agreement found was globally high, regardless of the level of training of the professionals, and whether or not they were a rheumatologist. Concordance was higher when compared to those who had more than 4 years of experience performing videocapillaroscopy.

Vacunación contra SARS-CoV-2 en pacientes con esclerosis sistémica en Argentina: preferencias, acceso y adherencia al plan de vacunación / Vaccination against SARS-CoV-2 in patients with systemic sclerosis in Argentina: preferences, access and adherence to the vaccination plan

Introducción: en pacientes con enfermedades reumatológicas autoinmunes se recomienda la aplicación sistemática y secuencial de una serie de vacunas para la prevención de enfermedades transmisibles. El objetivo de este estudio fue estimar la proporción de pacientes con esclerosis sistémica (ES) que recibieron vacunación contra el coronavirus (SARS-CoV-2). Materiales y métodos: se envió una encuesta anónima por correo electrónico o contacto por WhatsApp desde mayo a septiembre de 2021, con preguntas para evaluar la adherencia al esquema de vacunación recomendado en pacientes con enfermedades reumatológicas, así como temores, preferencias y adherencia al esquema de vacunación contra el SARS-CoV-2. Resultados: se incluyeron 295 pacientes con ES. El 68,81% estaba vacunado contra el SARS-CoV-2 con al menos una dosis, de los cuales el 48,7% tenía dos dosis. El 84,75% refirió conversar con su médico sobre su esquema de vacunación general. Solo el 5,4% tenía las cuatro vacunas. El 93,56% manifestó voluntad de vacunarse contra el SARS-CoV-2; el 56,27% prefirió la vacuna Sputnik V. El 7,46% manifestó su voluntad de no vacunarse. Los factores que influyeron en la adherencia a la vacunación, con mayor frecuencia, fueron el miedo a contraer la infección por SARS-CoV-2 (86,1%) y las reacciones adversas (23,05%). Conclusiones: destacamos el hecho de que solo 6 meses después de que se dispusiera la vacunación contra el SARS-CoV-2, la mitad de los pacientes con ES tenía el esquema recomendado completo.

Introduction: in patients with autoimmune rheumatic diseases, the systematic and sequential application of a series of vaccines is recommended for the prevention of communicable diseases. The objective was to estimate the proportion of patients with systemic sclerosis (SSc) who received vaccination against coronavirus (SARS-CoV-2). Materials and methods: since may to september 2021, an anonymous survey was sent by email or messaging app, containing questions to assess adherence to the recommended vaccination schedule in patients with rheumatic diseases, as well as fears, preferences and adherence to vaccination schedule against SARS-CoV-2. Results: 295 patients with SSc were included. 68.81% were vaccinated for SARS-CoV-2 with at least one dose, 48.7% of this group had two doses. 84.75% reported talking to their doctor about their general vaccination schedule. Only 5.4% had all four vaccines. 93.56% expressed willingness to be vaccinated against SARS-CoV-2, 56.27% preferred the Sputnik V vaccine. 7.46% expressed their willingness to not be vaccinated. The factors that most frequently influenced adherence to vaccination were fear of contracting SARS-CoV-2 infection (86.1%) and adverse reactions (23.05%). Conclusions: we highlight the fact that only 6 months after vaccination against SARS-CoV-2 became available, half of the patients with SSc had the full recommended schedule.

Criptococosis diseminada por terapia biológica, se debe gestionar el riesgo / Disseminated cryptococcosis by biological therapy: We must manage the risk

Introducción. Se han descrito múltiples efectos adversos con el uso de la terapia biológica para enfermedades autoinmunitarias, muchos de ellos secundarios al estado de inmunosupresión, como las infecciones bacterianas, fúngicas o virales. Caso clínico. Se presenta el caso de una mujer de 64 años con diagnóstico comprobado de criptococosis diseminada secundaria al uso de tofacitinib. Se descartaron otras causas de inmunosupresión, como infección por el virus de la inmunodeficiencia humana (HIV). Tres años antes se le había diagnosticado artritis reumatoide y se encontraba en tratamiento farmacológico con un agente biológico que inhibe las enzimas JAK. Se han descrito muy pocos casos de criptococosis pulmonar y meníngea en este tipo de pacientes. Conclusión. Este reporte de caso es útil para que otros médicos tratantes tengan presente la posibilidad de este tipo de infección fúngica invasora asociada con la terapia biológica y el enfoque de gestión de riesgo.

Introduction: Multiple adverse effects have been described for the biological therapy in autoimmune diseases including many secondary to immunosuppression producing bacterial, fungal, or viral infections. Clinical case: We present the case of a 64-year-old female patient with proven disseminated cryptococcosis secondary to the use of tofacitinib. Other possible causes of immunosuppression such as the human immunodeficiency virus (HIV) were ruled out. The patient had been in treatment for rheumatoid arthritis diagnosed three years before. This drug is a biological agent that inhibits JAK enzymes. Very few cases of pulmonary and meningeal cryptococcosis in this type of patient have been described in the literature. Conclusion: This case report should be useful for other clinicians to bear in mind the possibility of this type of invasive fungal infection associated with biological therapy and to take a risk-management approach.

Juarez (Chihuahua) and No. 49 Gabino Barreda (Veracruz Sur), with 1.7 first-time medical consultations and 148.3 subsequent medical consultations per 1,000 persons, respectively. While in UMF No. 40 Manlio Fabio Altamirano and No. 25 Cotaxtla, in Veracruz Norte, the highest burden was for RI, with 4.9 first-time medical consultations and 134.2 subsequent medical consultations per 1000 persons, respectively. Conclusions: The results could contribute to strengthening of medical units where it is necessary and the efficient allocation of resources available to meet the demand for health services of ND and RI in IMSS.

Guía de práctica clínica mexicana para el diagnóstico y tratamiento de las dislipidemias y enfermedad cardiovascular aterosclerótica / Mexican clinical practice guideline for the diagnosis and treatment of dyslipidemias and atherosclerotic cardiovascular disease

resumen está disponible en el texto completo

Abstract Background: Cardiovascular diseases are the leading cause of mortality worldwide and Mexico is no exception. The epidemiological data obtained in 1990 showed that cardiovascular diseases represented 19.8% of all causes of death in our country. This figure increased significantly to 25.5% for 2015. Some national surveys suggest that more than 60% of the adult population has at least one risk factor for cardiovascular disease (obesity or overweight, hypertension, smoking, diabetes, dyslipidemias). On the other hand, data from the Pan American Health Organization have linked the process of atherosclerosis as the first cause of premature death, significantly reducing life expectancy, which has enormous social repercussions. Objective: This document constitutes the Clinical Practice Guide (CPG) prepared at the initiative of the Mexican Society of Cardiology in collaboration with the Mexican Society of Nutrition and Endocrinology, AC, National Association of Cardiologists of Mexico, AC, Mexican Association for the Prevention of Atherosclerosis and its Complications, AC, National Normative Committee of General Medicine, AC, National College of Geriatric Medicine, AC, College of Internal Medicine of Mexico, AC, Mexican Society of Angiology and Vascular and Endovenous Surgery, AC, Mexican Institute of Research Nephrological, AC and the Mexican Academy of Neurology, A.C.; with the methodological support of the Ibero-American Agency for the Development and Evaluation of Health Technologies, in order to establish recommendations based on the best available evidence and agreed upon by an interdisciplinary group of experts. The objective of this document is to provide evidence-based recommendations to help decision makers in the diagnosis and treatment of dyslipidemias in our country. Material and methods: This document complies with international quality standards, such as those described by the Institute of Medicine of the USA, the Institute of Clinical Excellence of Great Britain, the Scottish Intercollegiate Guideline Network and the Guidelines International Network. A multidisciplinary group of clinical experts and methodologists with experience in systematic reviews of the literature and the development of clinical practice guidelines was formed. A scope document was agreed upon, relevant clinical questions were established, the best available evidence critically evaluated in systematic literature reviews was exhaustively identified, and clinical recommendations were developed. The modified Delphi Panel methodology was used to achieve an adequate level of consensus in each of the recommendations contained in this CPG. Results: 23 clinical questions were agreed upon which gave rise to their respective clinical recommendations. Conclusions: We consider that this document contributes to better clinical decision-making and becomes a point of reference for clinicians and patients in the management of dyslipidemias and this contributes to reducing the morbidity and mortality derived from atherosclerotic cardiovascular events in our country.

TRYPANOSOMA spp. in captive primates in a brazilian zoo

Captive animals, despite the constant care provided, are susceptible to infections from different sources. We herein report the natural trypanosome infection of 11 (28.2% positive) out of 39 non-human primates from 13 different species, in a Brazilian zoological park. Immunofluorescent antibody test (IFAT) and conventional polymerase chain reaction (cPCR) ruled out Trypanosoma cruzi, the etiological agent of Chagas disease. However, sequencing performed with positive samples employing hsp70 primers revealed similarities from 86% to 88% to diverse trypanosomes, including T. cruzi, Trypanosoma grayi, Trypanosoma lewisi, Trypanosoma rangeli and Trypanosoma vivax. We believe that the low similarity values obtained by sequencing reflect the difficulties in the molecular identification of trypanosomes, which share a large portion of their genetic material; this similarity may also preclude the diagnosis of co-infection by more than one trypanosome species. Thus, our study demonstrates the presence of diverse trypanosomes in primates, which are susceptible to infection by these parasites. Mechanical devices such as windows and bed nets, etc., are required to avoid vector insects in these environments, in addition to preventive quarantining of animals recently introduced into zoos. Therefore, investigation of the parasites in both the animals already residing in the zoo and those being introduced is of paramount importance, although no easy task.

Results: The protocol of care for emergency services Código Infarto is governed by evidence-based medicine and value-based medicine; it is guided by a principle of integrity that considers six dimensions of quality for the care of patients with STEMI. Conclusion: The protocol overcomes some adverse social determinants that affect STEMI medical care, reduces mortality and global economic disease burden, and develops medicine of excellence with high social reach.

Frequency of conjunctival epithelial dysplasia in patients with pterygium / Incidência de displasia do epitélio conjuntival em pacientes com diagnóstico de pterígio

ABSTRACT Purpose: To determine the frequency of ocular squamous surface neoplasia associated with pterygium in an ophthalmology reference center in Central Mexico. Methods: We reviewed histopathological reports and slides of all patients who underwent pterygium surgery from 2014 to 2016 at the Instituto Mexicano de Oftalmologia in Queretaro (Mexico). Results: We studied 177 biopsy samples; 66% were from women, and the median age was 52 years. We found ocular squamous surface neoplasias in 11.29% (n=20) of the samples. One biopsy sample revealed a poorly differentiated keratinizing and infiltrating carcinoma. Conclusions: The prevalence of ocular squamous surface neoplasia in our region appears to be high. Countrywide studies are necessary to determine the true prevalence of ocular squamous surface neoplasia in Mexico and to examine related risk factors.

RESUMO Objetivo: Determinar a frequência de neoplasia escamosa da superfície ocular associada ao pterígio com apresentação clínica, em um centro de referência em Oftalmologia da região central do México. Métodos: Revisamos os laudos histopatológicos e as lâminas de biópsia de todos os pacientes que foram submetidos à cirurgia de pterígio de 2014 a 2016 no Instituto Mexicano de Oftalmologia, na cidade de Querétaro. Resultados: Estudamos 177 amostras de biópsia; 66% eram de pacientes do sexo feminino, sendo a mediana da idade de 52 anos. Encontramos neoplasia escamosa da superfície ocular em 11,29% (n=20). Uma amostra de biópsia mostrou um carcinoma queratinizante infiltrativo pouco diferenciado. Conclusões: A prevalência da neoplasia escamosa da superfície ocular nessa região parece ser maior do que a indicada por outras pesquisas. Mais estudos de âmbito nacional são necessários para determinar a verdadeira prevalência da neoplasia escamosa da superfície ocular no México e examinar os fatores de risco relacionados.

Efecto de la rehabilitación cardiaca temprana en pacientes incluidos en Código Infarto / Effect of early cardiac rehabilitation in patients included in Codigo Infarto

Resumen Introducción: La rehabilitación cardiaca temprana (RCT) implementada en el protocolo Código Infarto (CI) es una estrategia en la atención del infarto agudo de miocardio. El objetivo fue identificar el efecto de la RCT en pacientes incluidos en CI. Método: Estudio de casos y controles. Se incluyeron pacientes consecutivos con diagnóstico de infarto agudo de miocardio ingresados a un hospital de cardiología entre febrero de 2015 y junio de 2017. Se crearon dos grupos: I y II, antes y después de CI y RCT. Resultados: Se incluyeron 1141 pacientes: 220 del grupo I y 921 del grupo II, edad 62.64 ± 10.53 años; 80.9 % hombres y 19.1 % mujeres. Los principales factores de riesgo para los grupos I y II fueron sedentarismo, 92.7 y 77.8 %; dislipidemia, 80.9 y 55.8 %; hipertensión, 63.2 y 62 %; tabaquismo, 66.8 y 59.2 %; y diabetes, 54.5 y 59.1 %. En el grupo II se inició antes la rehabilitación (1.8 ± 1.6 y 4.2 ± 3.2) y los días en terapia intensiva y hospitalización fueron menores (2.4 ± 2.2 y 4.8 ± 4.1; 8.6 ± 5.2 y 12.3 ± 7.7), así como los días de incapacidad (58.6 y 67.7). Conclusiones: CI y RCT son estrategias complementarias que permiten alta temprana de terapia intensiva y hospitalización, mejor calidad de vida y menos días de incapacidad laboral.

Abstract Introduction: Early cardiac rehabilitation (ECR) implemented in the Infarction Code (IC) protocol is a strategy in the care of acute myocardial infarction. The purpose of this study was to identify the effect of ECR in IC-included patients. Method: Case-control study. Consecutive patients diagnosed with acute myocardial infarction and admitted to a cardiology hospital between February 2015 and June 2017 were included. Two groups were created: I and II, before and after IC and ECR. Results: We included 1141 patients, 220 in group I and 921 in group II, with an age of 62.64 ± 10.53 years; 80.9 % were males and 19.1 % females. The main risk factors for groups I and II were sedentariness, 92.7 % versus 77.8 %; dyslipidemia, 80.9 % versus 55.8 %; hypertension, 63.2 % versus 62 %; smoking, 66.8 % versus 59.2 %; and diabetes, 54.5 % versus 59.1 %. Rehabilitation was started earlier (1.8 ± 1.6 versus 4.2 ± 3.2) and the days spent in intensive therapy and hospitalization were fewer in group II (2.4 ± 2.2 versus 4.8 ± 4.1 and 8.6 ± 5.2 versus 12.3 ± 7.7, p < 0.0001, respectively), as well as the days of disability (58.6 versus 67.7). Conclusions: IC and ECR are complementary strategies that allow an early discharge from intensive therapy and hospitalization, as well as better quality of life and fewer days of disability leave.

Formas de medición de la presión arterial sistémica: el debate continúa / Forms of measurement of systemic blood pressure: the debate continues

Resumen La medición de la presión arterial en el brazo continúa siendo la técnica patrón de referencia para el diagnóstico de hipertensión arterial sistémica. Sin embargo, las formas de medir la presión arterial han dado mucho de qué hablar en años recientes. Si bien los aparatos de medición con mercurio han sido desplazados por los digitales, ahora el cuestionamiento es dónde debe medirse la presión. A saber está la forma de medición en consultorio y los métodos fuera de él: medición intermitente domiciliaria o, bien, monitoreo ambulatorio de la presión arterial. Estos dos últimos han dado la oportunidad de identificar mejor el patrón de comportamiento y su variabilidad biológica, lo que acerca aún más al médico al conocimiento del comportamiento de las variaciones de presión en los sujetos con hipertensión arterial y prehipertensión. En esta revisión se discuten los alcances y limitaciones de cada forma de medición de la presión arterial.

Abstract The measurement of blood pressure in the arm continues to be the standard technique for the diagnosis of systemic arterial hypertension. However, the way to measure blood pressure has given much to talk about in recent years. While mercury-containing measuring have been displaced by digital devices, now questioning is where the pressure must be measured. To know this form of measurement in practice and methods outside the office: Home intermittent measurement or ambulatory blood pressure monitoring. These last two have given the opportunity to better identify the pattern of behavior and biological variability, what further approaches the medical knowledge of the behavior of the pressure variations in arterial hypertension and prehypertension subject carriers. In this review, we will discuss the scope and limitations of each form of measurement of blood pressure.

Efecto sobre la saciedad de un desayuno hiperproteico versus uno normoproteico y consumo prospectivo de alimentos durante el día en mujeres adultas / Effect on the satiety of a hyperproteic breakfast versus a normoproteic one and prospective consumption of food during the day in adult women

Introducción: resultan altamente complejos los mecanismos para controlar hambre y saciedad. Seleccionar preparaciones/alimentos más saciógenos podría ser una estrategia útil para controlar peso corporal. Objetivo: evaluar el efecto sobre la saciedad de un desayuno hiperproteico (HP) versus normoproteico (NP) y el consumo prospectivo de alimentos Ad libitum durante el resto del día en mujeres adultas. Metodología: ensayo clínico cruzado en mujeres voluntarias sanas (30 a 70 años), residentes en Gran Buenos Aires sur (Julio-Agosto 2014). Se aleatorizaron 60 participantes para consumir desayuno HP y NP durante tres días consecutivos cada uno, actuando las mismas mujeres como casos y autocontroles. Ambos desayunos fueron similares en densidad energética (1,22 y 1,23 kcal/g, respectivamente) y grasas, variando la relación proteínas/ carbohidratos (Pr/C): HP (41 g proteínas; P/C: 3,72) y NP (7 g proteínas; Pr/C: 0,13). Diariamente se registró saciedad percibida a cada hora del momento de ingerido (4 mediciones), mediante escala tipo Likert unidimensional (1= sin ganas de comer a 5= con muchas ganas de comer). Se calculó consumo de energía y macronutrientes aportados por alimentos consumidos Ad libitum durante el resto del día, mediante programa SARA-versión 1.2.12; grado de aceptación mediante escala hedónica verbal de cinco puntos (1=nada a 5= muchísimo) y elección del tipo de desayuno para su consumo habitual. Análisis de datos por SPSS 19.0, presentándose estadísticas descriptivas para comparación de muestras relacionadas no paramétricas y prueba de Wilcoxon, considerando nivel significativo p < 0,05. Resultados: edad media: 41 (DS=11,1) años. IMC: 25,8 (DS=7,4) kg/m². Fue mayor la aceptabilidad media del desayuno HP: 3,23 (DS=1,07) vs el NP: 2,72 (DS=1,05) (p=0,000). Sin embargo, la mayoría (58,3%) eligió para consumo habitual el desayuno NP vs el HP (33.3%) (p=0,01). La saciedad fue significativamente mayor con desayuno HP en la primera (p: 0,014), tercera (p: 0,048) y cuarta medición (p: 0,000). No se observaron diferencias en el consumo de alimentos Ad libitum después de ambos desayunos. Conclusiones: el desayuno HP contribuyó a controlar el apetito mejorando la saciedad a corto plazo respecto al desayuno NP. Sin embargo, a lo largo del día, no pudo observarse su efectividad dado que, independientemente del tipo de desayuno, el consumo de alimentos prospectivos Ad libitum fue similar.

Introduction: the mechanisms to control hunger and satiety are highly complex. Selecting preparations / foods more satiety could be a useful strategy to control body weight. Objective: to evaluate the effect of satiety of an hyperproteic breakfast (HP) versus a normoproteic (NP) one and prospective consumption of food Ad libitum during the rest of the day in adult women. Methodology: cross-sectional clinical test in healthy volunteer women (30 to 70 years old), residents of South Gran Buenos Aires (July-August 2014). Sixty participants were randomized to consume HP and NP breakfast for three consecutive days each, the same women acting as cases and self-controls. Both breakfasts were similar in energy density (1.22 / 1.23 kcal/g respectively) and fat, varying the protein/carbohydrate ratio (P/C): HP (41 g protein, P/C: 3.72) and NP (7 g proteins, P / C: 0.13). Daily perceived satiety was registered at each hour of the moment of ingestion (4 measurements), using one dimensional Likert scale (1= no desire to eat to 5= eager to eat). Energy consumption and macronutrients contributed by foods consumed Ad libitum during the rest of the day were calculated through SARA Program-version 1.2.12; degree of acceptance through five-point verbal hedonic scale (1= nothing to 5= very much) and choice of type of breakfast for their usual consumption. Data analysis by SPSS 19.0, presenting descriptive statistics for comparison of nonparametric related samples and Wilcoxon test, considering significant level p<0.05. Results: average age: 41 (SD=11.1) years old. BMI: 25.8 (SD=7.4) kg/m². The average acceptability of the HP breakfast was higher: 3.23 (SD=1.07) vs NP: 2.72 (SD=1.05) (p=0.000). However, the majority (58.3%) chose breakfast NP vs HP for usual consumption (33.3%) (p=.01). Satiety was significantly higher with HP breakfast in the first (p: 0.014), third (p: 0.048) and fourth measurement (p=0.000). No differences were observed in the consumption of Ad libitum foods after both breakfasts. Conclusions: the HP breakfast helped to control appetite by improving satiety in the short term compared to breakfast NP. However, throughout the day, its effectiveness could not be observed since, independently of the type of breakfast, the consumption of prospective foods Ad libitum was similar.

Afectación pancreática en infección por leptospirosis / Pancreatic involvement in leptospirosis infection

La leptospirosis en fase ictérica o enfermedad de Weil es una vasculitis zoonótica endémica de la Costa ecuatoriana. Sin embargo, la pancreatitis aguda como parte de esta entidad es una complicación rara vez documentada. En este reporte de caso se presenta a un adulto varón de 63 años con signos de falla multiorgánica y amilasa con rápido ascenso inicial. La leptospirosis no fue tomada como primera opción diagnóstica. El paciente fue tratado debido a un cuadro de SDRA como un shock séptico de foco pulmonar, con falla renal aguda que requirió hemodiálisis, permaneciendo en UCI con antibioticoterapia empírica. El objetivo de este caso es remarcar que la leptospirosis debe siempre estar considerada en el diagnóstico diferencial de ictericia y pancreatitis, sobre todo en nuestro medio.

The icteric presentation of Leptospirosis, also known as Weil's disease, is a zoonotic vasculitis endemic to Ecuador's coastal region. However, reports of pancreatic affection due to this entity are rarely documented. We chose to present the case of a 63 years old male with signs of catastrophic organic failure, associated with a rapid increase in serum amylase concentrations. Due to this presentation, Leptospirosis was not held as the primary culprit of the disease, and was treated at the ICU as septic shock of pulmonary origin with ARDS associated with acute kidney injury that required hemodialysis. Thus this case aims to highlight the importance of Leptospirosis as an important differential diagnosis in any patient hailing from a tropical region with jaundice and pancreatitis.

Anti-leptospirosis agglutinins in Brazilian capybaras (hydrochoerus hydrochaeris)

The interest in commercial use of wild animals is increasing, especially regarding raising of capybaras. Although this wild species is potentially lucrative for the production of meat, oil and leather, it is suggested as a probable reservoir of leptospires. Methods Due to the economic importance of this species and the lack of studies concerning leptospirosis, the presence of anti-leptospirosis agglutinins was assayed in 55 serum samples of capybaras (Hydrochoerus hydrochaeris) from commercial and experimental breeding flocks located in São Paulo state, Paraná state, and Rio Grande do Sul state, Brazil. Samples were obtained through cephalic or femoral venipunction (5 to 10 mL). Microscopic agglutination test was used according to the Brazilian Health Ministry considering as cut-off titer of 100. Results Out of the 55 samples analyzed, 23 (41.82 %) tested positive. The most prevalent serovar was Icterohaemorrhagiae (56.52 %) in 13 samples, followed by Copenhageni in nine samples (39.13 %), Pomona in four samples (17.39 %), Djasiman and Castellonis in three samples each (13.04 %), Grippotyphosa, Hardjo, Canicola, and Cynopteri in two samples each (8.7 %), and Andamana and Bratislava in one sample each (4.34 %). Conclusions These results suggest the evidence of exposure toLeptospira spp. and the need of new studies to evaluate a higher number of capybaras from different regions to better understand the importance of leptospirosis infection in these animals and verify the zoonotic role of this species as a possible source of infection to humans and other animals.

Occurrence of antibodies to Toxoplasma gondii in opossums caught in urban areas of Bauru, state of São Paulo, Brazil / Ocorrência de anticorpos para Toxoplasma gondii em gambás capturados na área urbana de Bauru, Estado de São Paulo, Brasil

Toxoplasmosis is one of the most common zoonoses worldwide. It was initially described in rodents and rabbits. There are few data on the morbidity and mortality of this disease among Brazilian marsupial fauna, such as opossums. These animals are of great importance regarding the epidemiology of this disease, given that they are prey for felids and other carnivores. With the aim of ascertaining the serological response to Toxoplasma gondii among marsupials (Didelphis spp.), 38 animals that had been caught in 14 districts of the urban area of the municipality of Bauru, state of São Paulo, were evaluated. The modified agglutination test (MAT) showed that 26.3% (10/38) of the samples analyzed were seropositive. It can be suggested that the opossums' behavior and persistent proximity to human housing results in contact with cats and T. gondii infection, based on the frequency found in this study. This was the first study on the seroprevalence of T. gondii in opossums caught in the urban area of the municipality of Bauru, SP, and it highlights the need for environmental and health authorities of the municipality to monitor this zoonosis.(AU)

A toxoplasmose é uma das zoonoses mais comuns no mundo, tendo sido descrita inicialmente em roedores e em coelhos. Todavia, poucos são os dados sobre morbidade e mortalidade da toxoplasmose nos marsupiais da fauna brasileira, como os gambás, sendo de grande importância na epidemiologia da doença, como presas para felídeos e outros carnívoros. Com o objetivo de verificar a resposta sorológica para Toxoplasma gondii em marsupiais (Didelphis spp.), foram avaliados 38 animais capturados em 14 regiões da área urbana do município de Bauru-SP. Foi encontrada uma frequência, de acordo com o teste de aglutinação modificada (MAT), de 26,3% (10/38) nas amostras analisadas. Pode-se sugerir que o comportamento dos gambás e sua permanência próxima a habitações humanas resultam em contato com gatos e infecção por T. gondii, tendo em vista a frequência encontrada neste estudo. Este é o primeiro estudo de soroprevalência de T. gondii em gambás capturados na área urbana do município de Bauru-SP, alertando-se para a necessidade do monitoramento desta zoonose pelas autoridades de vigilância ambiental e sanitária do município.(AU)
