ABSTRACT

BACKGROUND: Palivizumab is the standard immunoprophylaxis against serious disease due to respiratory syncytial virus infection. Current evidence-based prophylaxis guidelines may not address certain children with CHD within specific high-risk groups or clinical/management settings. METHODS: An international steering committee of clinicians with expertise in paediatric heart disease identified key questions concerning palivizumab administration; in collaboration with an additional international expert faculty, evidence-based recommendations were formulated using a quasi-Delphi consensus methodology. RESULTS: Palivizumab prophylaxis was recommended for children with the following conditions: <2 years with unoperated haemodynamically significant CHD, who are cyanotic, who have pulmonary hypertension, or symptomatic airway abnormalities; <1 year with cardiomyopathies requiring treatment; in the 1st year of life with surgically operated CHD with haemodynamically significant residual problems or aged 1-2 years up to 6 months postoperatively; and on heart transplant waiting lists or in their 1st year after heart transplant. Unanimous consensus was not reached for use of immunoprophylaxis in children with asymptomatic CHD and other co-morbid factors such as arrhythmias, Down syndrome, or immunodeficiency, or during a nosocomial outbreak. Challenges to effective immunoprophylaxis included the following: multidisciplinary variations in identifying candidates with CHD and prophylaxis compliance; limited awareness of severe disease risks/burden; and limited knowledge of respiratory syncytial virus seasonal patterns in subtropical/tropical regions. CONCLUSION: Evidence-based immunoprophylaxis recommendations were formulated for subgroups of children with CHD, but more data are needed to guide use in tropical/subtropical countries and in children with certain co-morbidities.

ABSTRACT

We present the case of a giant aneurysm and dissection of the abdominal aorta in an eight month old infant. Imaging studies especially a helicoid computerized axial tomography with 3D reconstruction, showed a lesion which extended from the diaphragm to the iliac arteries. The clinical findings and the above mentioned studies revealed non-obstructive heart rhabdomyomas, tubers in the brain and the abdominal aortic aneurysm, all of which were consistent with the diagnosis of tuberous sclerosis.


Presentamos el caso, de un niño de 8 meses con un aneurisma gigante de la aorta abdominal. La imagen de la tomografía axial computarizada helicoidal con reconstrucción tridimensional, mostró que dicha lesión iniciaba a nivel del diafragma y llegaba hasta las arterias ilíacas con disección de su pared. El cuadro clínico y los estudios apoyaron el diagnóstico de esclerosis tuberosa con rabdomiomas cardíacos, no obstructivos. Por la gravedad de dicha lesión, el desenlace fue fatal.

ABSTRACT

El estudio y tratamiento de las cardiopatías congénitas ha mostrado en los últimos 50 años un progreso acelerado. El ecocardiograma permite observar casi todas las características de las cardiopatías y el cateterismo tiene un carácter primordialmente terapéutico. La cirugía cardiaca es cada vez más temprana y con intenciones correctivas. Hoy en día hay una mayor sobrevida de estos pacientes que llegan a la vida adulta y por razones naturales procrean. Un aspecto que no había tenido este desarrollo es el conocimiento de la etiología de algunas cardiopatías. Con las técnicas de estudio molecular de los cromosomas se encontró la deleción de la región 11.2 en el brazo largo del cromosoma 22, en pacientes que comparten cardiopatía troncoconal y características fenotípicas como facies con puente de la nariz ancho, punta nasal recortada, anomalía en la forma e implantación de los pabellones auriculares y paladar alto, entre otros. Con la finalidad de saber cuales de nuestros pacientes tienen tal deleción, reunimos a aquellos con aspectos fenotípicos asociados a cardiopatías troncoconales. En los primeros dos pacientes a los cuales se les realizó estudio cromosómico de inmunofluorescencia in situ se comprobó deleción en la región 11.2 en el cromosoma 22. La importancia de estos resultados reside en que un porcentaje significativo de los pacientes que acuden a nuestra Institución tienen alteraciones troncoconales, el comprobar en algunos de ellos su etiología permite establecer la indicación del asesoramiento genético y el tratamiento adecuado a nivel cardiológico y del desarrollo psicológico.
