RESUMO

Abstract Background: Pulmonary embolism (PE) is a complication reported in the adult population with coronavirus disease 2019 (COVID-19); however, its documentation in the pediatric population is limiteda. Case report: We report the case of a 15-year-old male with obesity and Down syndrome who was admitted for severe COVID-19 pneumonia. On day 7 of admission, he presented with chest pain, hemoptysis, respiratory distress, and marked elevation of D-dimer. Pulmonary CT angiography found an extensive thrombus in the right lower lobar artery. He received treatment with enoxaparin and rivaroxaban and had a favorable clinical outcome. In the tomographic control 1 month after treatment, thrombus was not evidenced and was successfully resolved. Conclusions: There are few reports of PE in children with COVID-19. Prompt diagnosis and early anticoagulant treatment are important to avoid life-threatening complications.


Resumen Introducción: El tromboembolismo pulmonar es una complicación reportada en la población adulta con COVID-19; sin embargo, en la población pediátrica, su descripción es limitada. Caso clínico: Se reporta el caso de un varón de 15 años con antecedente de obesidad y síndrome de Down que fue hospitalizado por neumonía COVID-19 severa. En el séptimo día de hospitalización presentó dolor torácico, hemoptisis, dificultad respiratoria y elevación del dímero D. En la angiotomografía pulmonar se encontró un extenso trombo en la arteria lobar inferior derecha. Recibió tratamiento con enoxaparina y rivaroxabán evolucionando favorablemente. La resolución al mes de tratamiento fue existosa, ya que el control tomográfico no evidenció más el trombo. Conclusiones: El tromboembolismo pulmonar es una complicación poco reportada en niños con neumonía COVID-19. El diagnóstico oportuno y tratamiento anticoagulante es importante para evitar complicaciones mortales.

RESUMO

RESUMEN De toda la población infectada por el SARS-CoV-2, la población pediátrica representa del 1 al 5%, siendo un reto caracterizarla clínicamente. Presentamos cinco casos de pacientes pediátricos con diagnóstico de COVID-19; el rango de edad fue de 1 a 14 años, tuvieron manifestaciones clínicas variadas, tres de ellos presentaron fiebre, tos y dificultad respiratoria, otro fiebre y dermatosis, y un adolescente con diarrea y vómitos asociado al síndrome de Guillain-Barré. Los exámenes de laboratorio revelaron elevación de lactato deshidrogenasa, dimero-D y ferritina. El patrón radiológico más frecuente fue el engrosamiento peribronquial perihiliar. Todos los casos tuvieron evolución clínica y radiológica favorable. La diversidad en las presentaciones clínicas en niños debe considerarse para un diagnóstico temprano de la enfermedad.


ABSTRACT Children represent 1 to 5% of the entire SARS-CoV-2 infected population, and it is challenging to identify them based on clinical characteristics. We present 5 cases of pediatric patients diagnosed with COVID-19; the age range was from 1 to 14 years. They had different clinical characteristics, three of them presented fever, cough and respiratory distress, another one fever and dermatosis, and the other patient had diarrhea and vomiting associated with Guillain-Barre syndrome. Laboratory tests revealed elevated lactate dehydrogenase, D-dimer, and ferritin. The most frequent radiological pattern was perihilar peribronchial thickening. All cases had favorable clinical and radiological evolution. Diverse clinical characteristics should be considered for early diagnosis of COVID-19 in children.

RESUMO

RESUMEN La pandemia de COVID-19 ha traído una nueva afección grave e inusual denominada Síndrome Inflamatorio Multisistémico en niños, de la cual aún hay mucho por conocer. Presentamos una serie de 8 casos atendidos en el Instituto Nacional de Salud del Niño, Lima Perú. La edad media fue 5,1 años. La presentación clínica incluyó fiebre, problemas gastrointestinales agudos, afectación ocular y mucocutánea. Cuatro cumplieron criterios para Enfermedad de Kawasaki clásica. Todos tuvieron serología positiva para SARS-CoV-2, hemograma patológico, marcadores inflamatorios elevados y pruebas de coagulación alteradas. Cinco casos presentaron hipertransaminasemia y tres retención nitrogenada. Cuatro casos cumplieron criterios para Síndrome de Activación Macrófagica. Todos recibieron inmunoglobulina intravenosa, corticoides y ácido acetil salicílico. Ninguno desarrolló aneurismas coronarios. Solo uno presentó miocarditis, shock y requirió ingreso a Unidad de Cuidados Intensivos. La mayoría evolucionaron favorablemente. En todo niño con fiebre, síntomas gastrointestinales y dermatológicos; asociado a exposición al SARS-CoV-2, debe investigarse compromiso multisistémico.


ABSTRACT During the COVID-19 pandemic, a new, severe and unusual condition called Multisystem Inflammatory Syndrome in children emerged, from which there is still much to learn. We report 8 children admitted to Instituto Nacional de Salud del Niño, in Lima, Perú. Their mean age was 5,1 years. Their clinical presentation included fever, acute gastrointestinal symptoms, ocular and mucocutaneous involvement. Four patients met criteria for classic Kawasaki Disease. All the patients had positive serology for SARS-CoV-2, abnormal complete blood counts and coagulation tests, and elevated inflammatory markers. Five had elevated liver enzymes and three had kidney involvement. Four patients met criteria for Macrophage Activation Syndrome. All of them received intravenous immune globulin, corticosteroids and aspirin. No coronary aneurysms were identified. Only one developed miocarditis, shock and was admitted to the Pediatric Intensive Care Unit. Most patients recovered successfully. Every child with fever, gastrointestinal and dermatological symptoms, associated with prior exposure to SARS-CoV-2, should be investigated for multi-systemic compromise.

RESUMO

Bovine tuberculosis, caused by Mycobacterium bovis, is a disease of socio-economic and public health importance and of significance to international trade regulation. Allelic variants of several genes have been implicated in the genetic susceptibility to tuberculosis in some human populations, but little is known in cattle. We surveyed 34 European, 18 Asian, 20 Creole and 23 hybrid bovines for polymorphisms of the bovine solute carrier family 11 a1(Slc11a1) gene, formerly known as natural resistance associated macrophage protein (Nramp1), gene by typing the cattle using two microsatellite loci closely linked to this gene. The microsatellites used were 311-22, located at the 3' untranslated region (3' UTR) of the Slc11a1 gene, and ARO28 situated about 0.6 cM upstream of the same gene Based on allele size in base pairs (bp) we determined five 311-223 locus variants (221, 223, 225, 227 and 229 bp) and 12 ARO28 loci. There was marked diversity and a very high level of heterozygosity in most of the cattle surveyed except the Europeans bovines and especially Holsteins in relation to the 3' UTR microsatellite locus.

RESUMO

La aorto-arteritis inespecífica de Takayasu (AT) es una vasculitis idiopática que afecta la aorta, sus ramas principales y a veces la arteria pulmonar. Es una enfermedad prevalente en todo el mundo -pero con predilección en razas orientales y mestizos hispanoamericanos- que afecta mujeres jóvenes y su causa es desconocida. Desde hace 50 años se ha sospechado su relación con tuberculosis. En este trabajo se encontró que el suero de los pacientes con AT tiene un anticuerpo IgG específico para una glicoproteína de 38 kDa, que es un marcador serológico de infección por mycobacterium tuberculosis. Es probable que la AT sea una vasculitis postinfecciosa con patogenia de base inmunológica.

RESUMO

Intestinal amebiasis is still an important health problem in developing regions of the world. In order to advance our knowledge on the pathogenesis and to test the relevance of recently obtained in vitro observations, suitable in vivo experimental models of intestinal amebiasis are needed. In the past a variety of laboratory animals have been used, but the mouse, whose genetic and immunology is well known, has been seldomly used. Therefore, Entamoeba histolytica strain HM1:IMSS was directly inoculated into the cecum of C3H/HeJH mice, which were sacrified at 5, 10, 15, 20, 25 and 30 days for histopathologic analysis. An ulcerative inflammatory disease highly reminiscent of human amebiasis was observed. Early 5 day lesions consited of tiny erosions of the surface epithelium which evolved to deeper and more extensive destructive lesions of the cecal wall. Indeed, flask-shaped ulcers, intestinal perforations and intramural abscess formation were observed at later time. It was noticeable that, depite the lack of obvious significant tissue invasion by amebae, ulcerative disease was extensive and found virtually in all mice. These observations support the view that tissue invasion by trophozoites is not necessarily required for ulcerative disease to occur, suggesting a role for toxic factors released by amebae

RESUMO

Se valoraron los síntomas y signos de enfermedad hepática en 150 pacientes de transplante renal estudiados en el Hospital General del Centro Médico Nacional del Instituto Mexicano del Seguro Social entre agosto de 1976 y junio de 1981. De ellos, 11 desarrolaron hepatopatía, nueve hepatitis aguda por virus y dos hepatitis tóxicas por medicamentos. De los nueve primeros, siete correspondieron a hepatitis B, uno a hepatitis no A no B y el otro a hepatitis por citomegalovirus (CMV). Seis casos de hepatitis B tuvieron evolución favorable, uno desarrollo hepatitis crónica activa, el paciente con hepatitis no A no B evolucionó hacia la cirrosis y el paciente con hepatopatía por CMV falleció. Los dos casos de hepatitis por medicamentos evolucionaron favorablemente al cambiar la azatioprina por otro agente inmunosupresor. Se estudió un grupo testigo de 21 pacientes con insuficiencia renal crónica tratados con hemodiálisis crónicas por un promedio de 16 meses. De ellos, cuatro tuvieron hepatitis aguda tipo B (20 por ciento) y en tres más (15 por ciento) apareció el AgsHB sin enfermedad hepática, lo que representa 35 por ciento de riesgo de contagio de virus de la hepatitis B
