[Familial aggregation in 91 families of hypercholesterolemic children]. / Estudio de la agregación familiar en 91 familias de niños hipercolesterolémicos.

OBJECTIVE: The aim of this study was to evaluate both the importance of the screening strategy and the familial aggregation characteristics of families with hypercholesterolemic children. PATIENTS AND METHODS: Ninety-one families (369 subjects) with one hypercholesterolemic child were studied. In addition to clinical and general biochemical evaluation, lipids including apo A-I and B-100 were examined. LDL was quantified under ultracentrifugation. RESULTS: Among the 91 children studied, 10 (10.99%) suffered heterozygous hypercholesterolemia, while 81 (89.01%) suffered polygenic hypercholesterolemia. Following a diet, polygenic children exhibited normal lipid parameters. In heterozygous children a decrease of 19% for total cholesterol, 19.9% for LDL-cholesterol and 16.3% for apo B were observed. When starting the study, 77.5% of the family members thought that they had normal serum lipid values. At the end of the study it was confirmed that only 28% were really normolipemic, indicating that 49.4% of the individual did not know that they were suffering dyslipemia. The study also showed that fathers exhibited the highest incidence of hypercholesterolemia (80.2%) followed by brothers (65.6%) and mothers (61.5%). Therefore, 69.4% of the individuals studied exhibited dyslipemia. CONCLUSIONS: The screening strategy allows one to diagnose a high percentage (almost 50%) of individuals suffering hypercholesterolemia in families with a child previously diagnosed of this pathology. Moreover, in these families there is a high degree of familiar aggregation of dyslipemia.

Crouzon disease with acanthosis nigricans and melanocytic nevi.

A number of craniofacial malformation syndromes are characterized by prominent abnormalities of the skin, hair, nails, and mucous membranes. Crouzon disease has been reported in association with severe acanthosis nigricans in 12 patients. We report a new case of this association in a 16-year-old woman with multiple melanocytic nevi. Melanocytic nevi have been already reported in the medical literature in association with several congenital syndromes, although, to our knowledge, not with Crouzon disease.
