[The Turner syndrome and cardiovascular changes].

Nineteen consecutive patients with Turner's syndrome and different karyotypes underwent full cardiological evaluation (physical examination, electrocardiogram, chest X-ray and echocardiogram). Congenital heart disease was found in 26%. Other cardiovascular pathologies (long QT syndrome or systemic hypertension) were found in two patients. When compared with the general population, a higher incidence was present for all types of congenital heart diseases observed. Among cardiac anomalies in Turner's patients, aortic malformations (aortic coarctation and bicuspid aorta) were the most frequent, followed by patent ductus arterious and pulmonary valve stenosis. We have observed that the most severe malformations were preferably found with the 45,X karyotype. Pulmonary valve stenosis was found in a mosaicism 45,X/46,XX case. No anomaly was found in patients with X isochromosome. The ring pattern was not found in our series.

[Hair grooming syncope].

INTRODUCTION: Syncope is a frequent topic in pediatric emergency rooms. Most of them are vasovagal syncopes. Some specific forms have been admitted, according to their etiopathogenic and clinical characteristics. Hair-grooming syncope is a rare variety which is not yet fully recognized. PATIENTS AND METHODS: The records of children referred to our Pediatric Cardiology clinic from 1993 to 1996 because of fainting were evaluated. Patients with clinical data in possible relation with hair-grooming syncope were elected for the present study. Physical, cardiological and neurological examinations were recorded as well as basic complementary examinations. Head-upright tilt test was performed in all cases. RESULTS: Four girls, with a mean age of 9.5 years, presented sudden and brief loss of consciousness and postural tone in temporal relationship with several hair care acts. No body or neck position was associated with faint. Three patients had previously suffered other syncopal episodes without relation with hair care. Head-upright tilt test was positive in three cases and inconclusive in a girl with clear antecedents of clinically vasovagal syncope. CONCLUSION: Hair-grooming syncope is a rare and benign variety of neurocardiogenic syncope that should be considered in girls that complain of loss of consciousness during different hair care acts, even if seizures are present.

[Electrocardiographic semiology of progressive Duchenne's muscular dystrophy].

The authors studied the ECGs of 21 boys with Duchenne's progressive muscular dystrophy (group D) aged from 8 months to 10.5 years. They were compared with 21 age matched healthy boys. There were no statistical significant differences between both groups on maximal or minimal heart rates, nor on their subtractions. There were no differences between the electrical axis of P, QRS or T waves in the frontal plane, nor in the duration or amplitude of P waves. R wave in V1 had 1.06 +/- 0.38 (mean +/- 1 standard deviation) mV in group D, and 0.62 +/- 0.29 mV in group C (p less than 0.001). R/S ratio in V1 was 1.24 +/- 0.53 in group D, and 0.70 +/- 0.50 in group C (p less than 0.01). Q wave in V6 had 0.27 +/- 0.18 mV in group D, and 0.13 +/- 0.09 mV in group C (p less than 0.01). Q/R ratio in V6 was 0.19 +/- 0.14 in group D, and 0.09 +/- 0.047 in group C (p less than 0.01). Sensibility, specificity, positive predictive value, and negative predictive values for signs over 75 percentile (Davignon standards) were: for R wave in V1 71.4%, 76.2%, 75%, and 72.7%; for R/S ratio in V1 71.4%, 76.2%, 75% and 72.7%; for Q wave in V6 38.1%, 85.7%, 72.7%, and 58%.
