We have shown that cIMT is positively associated with BMI increase in adolescents, even in moderate overweight ranges, independent of age, gender, systolic blood pressure and plasma lipid concentrations.

Diabetic neuropathy is a heterogeneous group that still lacks adequate comprehension. Its approach is empirical and demands exclusion of other etiologies. A definitive diagnosis is not always possible and sometimes is retrospective.

Background: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) is an autosomal recessive disorder characterized by 3 overlapping phenotypes: salt-wasting (SW), simple virilizing (SV), and non-classic (NC). We aimed at conducting a nationwide genotype description of the CAH pediatric patients and to establish their genotype–phenotype correlation. Methods: CAH patients were recruited from Portuguese pediatric endocrinology centers and classified as SW, SV, or NC. Genetic analysis was performed by polymerase chain reaction (sequence specific primer, restriction fragment length polymorphism) or direct Sanger sequencing. Genotypes were categorized into 4 groups (0, A, B, and C), according to their predicted enzymatic activity. In each group, the expected phenotype was compared to the observed phenotype to assess the genotype–phenotype correlation. Results: Our cohort comprises 212 unrelated pediatric CAH patients (29% SW, 11% SV, 60% NC). The most common pathogenic variant was p.(Val282Leu; 41.3% of the 424 alleles analyzed). The p.(Val282Leu) variant, together with c.293-13A/C>G, p.(Ile173Asn), p.(Leu308Thr), p.(Gln319*), and large deletions/conversions were responsible for 86.4% of the mutated alleles. Patients’ stratification by disease subtype revealed that the most frequent pathogenic variants were c.293-13A/C>G in SW (31.1%), p.(Ile173Asn) in SV (46.9%), and p.(Val282Leu) in NC (69.5%). The most common genotype was homozygosity for p.(Val282Leu; 33.0%). Moreover, we found 2 novel variants: p.(Ile161Thr) and p.(Trp202Arg), in exons 4 and 5, respectively. The global genotype-phenotype correlation was 92.4%. Group B (associated with the SV form) showed the lowest genotype–phenotype correlation (80%). Conclusion: Our cohort has one of the largest NC CAH pediatric populations described. We emphasize the high frequency of the p.(Val282Leu) variant and the very high genotype–phenotype correlation observed.

INTRODUÇÃO O sono apresenta um papel vital no crescimento e desenvolvimento das crianças sendo, no entanto, as suas perturbações frequentemente subdiagnosticadas. 1 É um processo fisiológico complexo, influenciado por propriedades biológicas intrínsecas, temperamento, expectativas, normas culturais e condições ambientais. 2 Estudos demonstram que tanto os médicos como os pais não estão, em muitos casos, preparados para iden

Tuberculosis remains a real problem, with the diagnosis, the search for contacts and adequate treatment (including prophylaxis) the main challenge.
