Alteraciones cardiológicas en niños con enfermedad neuromuscular

Fundamento Describir las alteraciones cardiologicas detectadas en ninos con diferentes enfermedades neuromusculares (ENM). Poblacion y metodo En 40 pacientes con ENM, se estudiaron las alteraciones cardiologicas detectadas mediante auscultacion cardiaca, radiografia de torax, electrocardiografia (ECG), Holter ECG ambulatorio y ecografia Doppler. Resultados Se hallaron las siguientes alteraciones: taquicardia sinusal, bradicardia sinusal, R/S anormal en V1, onda Q profunda, alteraciones en la repolarizacion, anormalidades en la conduccion, extrasistoles auriculares y ventriculares, sindrome de Wolff-Parkinson-White, prolapso de la valvula mitral y miocardiopatia dilatada. Conclusion La asociacion de alteraciones cardiologicas en ninos con ENM es frecuente. La monitorizacion convencional ECG, el Holter ECG y la ecocardiografia permiten su diagnostico y seguimiento.

Deficiencia de vitamina D en niños aragoneses sanos

BACKGROUND the main action of vitamin D is to maintain the concentration of calcium and phosphorus within the physiological range, allowing normal metabolism and bone mineralization. Vitamin D receptors have recently been described in many tissues, therefore vitamin D deficiency has been related not only to rickets, but also to increased risk of diabetes, obesity, cardiovascular, oncological, infectious and autoimmune diseases. OBJECTIVE the aim of the study was to know the vitamin D concentration in a healthy pediatric population and to verify its influential factors, as well as to analyze the current situation of vitamin D prophylaxis and to evaluate the effectiveness of current recommendations. METHODS one hundred and seven healthy patients aged between one and 15 years were selected, who required a blood test as a preoperative minor surgery and whose pathology did not influence the parameters of the study. RESULTS the sample analyzed had a total of 78.5% males and a mean age of 7.17 ± 3.79 years. Mean values of vitamin D were 26.07 ± 7.11 ng/ml; up to 72.9% had insufficient levels. The sample was divided into two groups: patients with hypovitaminosis D and patients with optimal vitamin D levels. A predominance of males with a higher body mass index, from immigrant parents, and the presence of extreme phototypes were observed in the hypovitaminosis group. There was also a higher risk of hypovitaminosis in those who had not performed prophylaxis during the first year of life. CONCLUSIONS the high percentage of healthy children with vitamin D deficiency is evident, and current recommendations for prophylaxis are not carried out by the population as recommended by current guidelines.
