ABSTRACT

La Queratodermia Aquagénica (QA) es una enfermedad adquirida poco frecuente de tipo transitoria que se localiza de preferencia en palmas de manos y raramente en la planta de los pies. Mujer de 20 años, portadora de Fibrosis Quística (FQ) que consulta por lesiones en palmas de manos de aspecto blanquecino macerado que aparecen al tener contacto con el agua y que desaparecen en pocos minutos del secado. Se realiza estudio histológico cuyo resultado confirmo el diagnóstico de Queratodermia Aquagénica. Esta enfermedad se relaciona con Fibrosis Quística, Raynaud, entre otros. Se manifiesta al humedecer las manos y pies. Presentamos el caso por ser inusual y la importancia de sus asociaciones con otras enfermedades.


Aquagenic Keratoderma is a rare acquired disease of a transitional type, which is preferably located in the palms of the hands and very rarely in the soles of the feet. The case of a twenty-year-old woman with Cystic Fibrosis, who consulted for lesions in her palms with a whitish macerated aspect that appeared with the contact of water and disappeared a few minutes after drying. Histological studies have been done confirming the Aquagenic Keratoderma diagnostic. This disease is related to Cystc Fibrosis and Raynaud, among others. It manifests when the palms of the hands and the soles of the feet get wet. We present this case because it is unusual and because of the important association with other diseases.

ABSTRACT

La obesidad es la causa más común de insulinorresistencia en niños y adolescentes. La misma presenta un aumento de su prevalencia involucrando a todos los grupos etarios. La insulinorresistencia determina disturbios metabólicos que son deletéreos para el árbol vascular y otros tejidos. Además se demostró una asociación entre insulinorresistencia e hiperinsulinemia con mayor prevalencia de nódulos tiroideos y aumento del tamaño de la tiroides, que estaría relacionado a la acción bociógena de la insulina y el IGF-1. El objetivo fue evaluar la prevalencia de factores de riesgo cardiovasculares, la presencia de esteatosis hepática y su asociación con hiperinsulinismo. Realizamos un estudio transversal descriptivo de 75 niños entre 2 y 14 años que consultaron al Servicio de Endocrinología en un lapso de 14 meses. Se analizaron las siguientes variables: peso, talla, índice de masa corporal (IMC), glucemia, insulinemia, índice HOMA, acantosis nigricans, transaminasas hepáticas, perfil lipídico, cortisol 8 hs, perfil tiroideocon anticuerpos, ecografía tiroidea y abdominal. Encontramos que 60% de la población presentó niveles de insulina elevados (>15 μUI/ml) con aumento progresivo de la prevalencia de acantosis nigricans, el 12,3% tuvo glucemias alteradas de ayuno y 66,6% índice HOMA >3. El 90% de los pacientes con ecografía tiroidea heterogénea presentó hiperinsulinismo (p <0,05), hallándose nódulos tiroideos en 5 (9,8%) de ellos. Evaluamos la posible relación entre nódulos tiroideos e hiperinsulinismo, y encontramos una asociación positiva en el 80%. La obesidad infantil de beser considerada un problema de salud pública.


besity is the most common cause of insulin resistance in children and adolescents. It has increasing prevalence and involves all age groups. Insulin resistance determines metabolic disturbances that are deleterious to the vasculature and other tissues. An association between insulin resistance and hyperinsulinemia on the one side and increased prevalence of thyroid nodules and enlargement of the thyroid gland on the other has been demonstrated, which could be related to the goitrogenic action of insulin and IGF-1. The aim of this study was to evaluate the prevalence of cardiovascular risk factors, the presence of hepatic steatosis and its association with hyperinsulinism. We performed a cross sectional study of 75 children between 2 and 14 years (mean 10 years) who visited the Department of Endocrinology during a span of 14 months. We analyzed the following variables: weight, height, body mass index (BMI), glucose, insulin, HOMA, acanthosis nigricans,liver transaminases, lipid profile, cortisol at 8 AM, thyroid function tests and thyroid antibodies, thyroid and abdominal ultrasonography. In our study we found that 60% of the population showed elevated insulin levels (>15 μIU/ml) with progressive increase in the prevalence of acanthosis nigricans, and 12.3% showed inappropriate glucose levels...

In our study we found that 60% of the population showed elevated insulin levels (>15 ìIU/ml) with progressive increase in the prevalence of acanthosis nigricans, and 12.3% showed inappropriate glucose levels. Ninety per cent of patients with heterogeneous thyroid ultrasonography had hyperinsulinemia (p <0.05), and thyroid nodules were found in 5 of them (9.8%). We assessed the possible relationship between thyroid nodules and hyperinsulinism, and founda positive association in 80% of the cases. Childhood obesity should be considered a public health problem.

ABSTRACT

A hipoglicemia hiperinsulinêmica da infância (HHI) é uma emergência no período neonatal. Após curtos períodos de jejum, o cérebro ávido por glicose corre o risco de ficar sem seu principal substrato energético. Os critérios de diagnóstico de HH, tanto no período neonatal quanto na criança maior e na adolescência, foram revisados. Foram descritas as etiologias e a fisiopatologia da HHI. As alterações moleculares frequentemente encontradas, bem como a descrição das principais mutações, são abordadas.


The hypoglycemia hyperinsulinemic of the infancy (HHI) is an emergency in the neonatal period. After a short period of fast the avid brain runs out of its main energy substrate. The authors overhaul the diagnosis of HH, not only in the neonatal period, but also in the late infant and in the adolescence. The aspects of the molecular alterations found in these cases, as well like the description of the main mutations are also approached.
