RESUMO

Resumen El aborto enzootico ovino es una enfermedad causada por Chlamydia abortus. Es considerada una zoonosis y una de las principales causas de pérdidas económicas en estas explotaciones. Este trabajo se enfocó en utilizar el cultivo de leucocitos de animales sin signos de abortos y la detección de anticuerpos para determinar la posible presencia de C. abortus en explotaciones de traspatio. Se obtuvieron 42 muestras de sangre periférica de ovejas de diferentes poblaciones. La detección de Chlamydia abortus se realizó mediante la tinción de Giemsa y la técnica de PCR. La detección de anticuerpos anti-C. abortus se dio mediante una técnica de ELISA comercial. Los resultados mostraron 21 muestras positivas mediante la técnica de PCR, de las cuales solo 10 fueron positivas mediante la técnica de Giemsa, mientras que 22 sueros mostraron anticuerpos anti-C. abortus. En este estudio el 38,1 % de las muestras fueron positivas a la infección por C. abortus, como se confirmó mediante PCR y serología. En conclusión, los leucocitos de sangre periférica pueden ser útiles para detectar una infección por Chlamydia spp. en explotaciones sin historial de abortos, con lo que se puede conocer la prevalencia real del aborto enzootico ovino en México.


Abstract The Ewes Enzootic Abortion is a disease caused byChlamydia abortus. It is deemed a zoonosis and one of the leading causes of financial losses in this type of business. This article focuses on using the culture of leukocytes from animals without any abortion symptoms and antibody detection to determine the potential presence ofC. abortusin backyard exploitations. Forty-two samples of peripheral blood were obtained from ewes in different populations. The detection ofChlamydia abortuswas carried out by using the Giemsa dye and PCR technique. Anti-C. Abortusantibody detection was performed through a commercial ELISA technique. Results showed 21 positive samples using the PCR, and only ten were positive according to the Giemsa dye, while 22 serum samples showed anti-C. abortusantibody. In this study, 38.1% of the samples were positive for theC. abortusinfection, as verified with the PCR and serology. In conclusion, peripheral blood leukocytes can be helpful to detect an infection caused byChlamydiaspp. Animal exploitation without any previous abortion allows knowing the real prevalence of ewes' enzootic abortion in Mexico.

RESUMO

Introducción. El síndrome de Ritscher-Schinzel (también conocido como displasia cráneo-cerebelo-cardíaca o síndrome 3C) es un síndrome genético raro que se caracteriza principalmente por la asociación de anomalías cardíacas, craneofaciales y de la fosa posterior. Pacientes y métodos. Se describen 26 pacientes con síndrome de Ritscher-Schinzel pertenecientes a un hospital de Medellín en el departamento de Antioquia, Colombia. Resultados. La presente cohorte está compuesta en un 69% por hombres. La mediana de edad de la cohorte fue de 30 meses y el 42% tenía menos de 1 año de edad en el momento del diagnóstico. Todos presentaban afectación ocular, y la megalocórnea fue la manifestación ocular más frecuente (69%), mientras que las orejas de implantación baja (80,7%) y los defectos cardíacos septales (68,7%) fueron las malformaciones faciales y cardíacas más comunes, respectivamente. Las malformaciones de la fosa posterior más frecuentes fueron megacisterna magna (31,8%) y malformación de Dandy-Walker (27%). El 84% tenía retraso del neurodesarrollo o discapacidad intelectual. Las manifestaciones esqueléticas fueron frecuentes: el conjunto de camptodactilia, pliegue palmar único, dedos sobrelapados, astrágalo vertical e hipoplasia ungueal en las manos y los pies se halló en el 96% de los casos. Conclusiones. El síndrome de Ritscher-Schinzel es heterogéneo desde el punto de vista genético y clínico. Estos resultados sugieren que las anormalidades esqueléticas y oculares observadas pueden facilitar el diagnóstico fenotípico. No obstante, es necesario realizar estudios adicionales que permitan conocer mejor su prevalencia y facilitar la identificación de otros genes implicados en este síndrome (AU)


Introduction. Ritscher-Schinzel syndrome (also known as cranio-cerebello-cardiac dysplasia or 3C syndrome) is a rare genetic syndrome that is mainly characterised by the association of cardiac and craniofacial anomalies together with others affecting the posterior fossa. Patients and methods. We report on 26 patients with Ritscher-Schinzel syndrome at a hospital in Medellín, in the Department of Antioquia, Colombia. Results. Males account for 69% of this cohort. The mean age of the cohort was 30 months, and 42% were under the age of one year at the time of diagnosis. All of them presented ocular disorders, and megalocornea was the most frequent ocular manifestation (69%), whereas low-set ears (80.7%) and septal heart defects (68.7%) were the most common facial and cardiac malformations, respectively. The most frequent malformations of the posterior fossa were megacisterna magna (31.8%) and Dandy-Walker malformation (27%). 84% of the cases had delayed neurodevelopment or intellectual disability. Skeletal manifestations were frequent: the group consisting of camptodactyly, single palmar crease, overlapping fingers, vertical talus and nail hypoplasia were found in hands and feet in 96% of the cases. Conclusions. Ritscher-Schinzel syndrome is a heterogeneous syndrome from the genetic and clinical point of view. These results suggest that the skeletal and ocular abnormalities that were observed can facilitate the phenotypic diagnosis. However, it is necessary to conduct further studies that allow us to gain a deeper knowledge of its prevalence and help identify other genes involved in this syndrome (AU)

RESUMO

La enfermedad del pulmón de granjero (EPG) es una forma de neumonitis por hipersensibilidad (NH) producida por la inhalación de microorganismos procedentes del heno o grano almacenado en condiciones de alta humedad en el ámbito laboral agrícola. Se trata de una enfermedad probablemente infradiagnosticada, sobre todo en el Norte de España, donde las condiciones climáticas son propicias para el desarrollo de la misma. Según estudios previos los antígenos más frecuentes suelen ser hongos y actinomicetos termofílicos. La epidemiología de la enfermedad no es del todo bien conocida, y se basa en estudios realizados por grupos centroeuropeos y asiáticos. La presentación clínica puede ser variada, diferenciándose las formas agudas (tras exposición a elevadas concentraciones del antígeno) y las crónicas (exposición a menores concentraciones del antígeno, pero más prolongada en el tiempo). En estos casos es esencial, en aquellos pacientes con clínica respiratoria durante la exposición laboral agrícola, demostrar una radiología y función pulmonar compatible, así como una sensibilización al antígeno, una linfocitosis en el lavado broncoalveolar en su caso y/o una anatomía patológica concordante. El tratamiento principal es la evitación antigénica, por lo que la educación de los pacientes en las medidas preventivas es fundamental. Por el momento, no existen estudios controlados que permitan evaluar el papel de tratamientos inmunosupresores en esta enfermedad. El tratamiento con corticosteroides solo ha demostrado acelerar la resolución de las formas agudas, pero no hay estudios que demuestren su efectividad a largo plazo, con el fin de evitar la progresión de la enfermedad ni disminuir su mortalidad


Farmer's lung disease (FLD) is a form of hypersensitivity pneumonitis (HP) caused by inhaling microorganisms from hay or grain stored in conditions of high humidity in the agricultural workplace. It is probably underdiagnosed, especially in northern Spain, where climatic conditions favor the development of this disease. According to previous studies, the most common antigens are usually thermophilic actinomycetes and fungi. The epidemiology of the disease is not well known, and is based on studies conducted by Central European and Asian groups. The clinical presentation may vary, differentiating the chronic (exposure to lower concentrations of the antigen over a longer period time) and the acute forms (after exposure to high concentrations of the antigen). In patients with respiratory symptoms and agricultural occupational exposure, radiological, lung function and/or anatomical pathology findings must be compatible with FLD, bronchoalveolar lavage must show lymphocytosis, and tests must find sensitivity to the antigen. The main treatment is avoidance of the antigen, so it is essential to educate patients on preventive measures. To date, no controlled studies have assessed the role of immunosuppressive therapy in this disease. Corticosteroid treatment has only been shown to accelerate resolution of the acute forms, but there is no evidence that it is effective in preventing disease progression in the long-term or reducing mortality

RESUMO

Unlike Goodpasture's syndrome with diffuse alveolar hemorrhage (DAH), there are scarce reports on the use of plasmapheresis for patients with a recurrence of DAH associated with antineutrophil cytoplasmic antibody (ANCA)-associated small vessel vasculitis (AAV) on hemodialysis. We report a case of a relapse of perinuclear-AAV with DAH, five months after starting hemodialysis. The patient received apheresis and induction immunosuppressive therapy, added to a short course of daily hemodialysis treatments. The DAH resolved with seven apheresis procedures and there were no adverse effects. We suggest that patients on hemodialysis with a relapse of AAV and DAH would benefit from the prompt initiation of apheresis in combination with aggressive immunosuppressive therapy. Pulmonary hemorrhage is not included in the current guidelines for therapeutic apheresis; therefore, we report this case and, if warranted, propose this condition to be included in the guidelines.
