BackgroundCongenital Adrenal Hyperplasia (CAH) is an endocrine disorder characterized by enzymatic deficiency in adrenal steroidogenesis, leading to adrenal insufficiency and hyperandrogenism. Patients need continuous hormone replacement therapy, but adequate control has proven challenging, exposing patients to undesirable consequences of both disease and treatment.ObjectiveTo evaluate the health related quality of life (HRQoL) of children and adolescents with CAH due to 21-hydroxylase deficiency.MethodsIn an analytical study, generic questionnaires, validated and translated versions, Pediatric Quality of Life Inventory 4.0 (for self-assessment of patients) and Child Health Questionnaire - PF50 (for parents) were applied and mean scores were analyzed with Student’s t-test.ResultsWe included 25 patients (19 female) with classical CAH (14 salt wasting/11 simple virilizing), mean age ± standard deviation (SD) of 11.4 ± 3.6 years (5–17.9), and their parents. Self-assessment of HRQOL showed decrease in mean scores: overall (67.8 ± 15.5 vs. 88.9 ± 7.4, p value = 0.015) and in the physical (75.2 ± 15.0 vs. 95.9 ± 5.8, p value = 0.014) and psychosocial (63.9 ± 17.8 vs. 85.0 ± 9.6, p value = 0.023) dimensions of patients, compared to healthy controls (previously published national data on children and adolescents). The assessment of the parent’s view was concordant, also showing losses in the physical (43.7 ± 8.0 vs. 55.1 ± 3.6, p value = 0.013) and psychosocial (41.9 ± 9.7 vs. 53.0 ± 7.0, p value = 0.025) dimensions. The comparison of HRQOL between subgroups 1) males versus females and 2) salt-wasting versus simple virilizing showed no significant differences.ConclusionThere seems to be a loss of HRQOL in children and adolescents with classical CAH. The self-assessment was concordant in key areas with the assessment made by their parents. No differences were observed between genders or clinical presentation of the disease.

Septo-optic dysplasia (SOD), also referred to as de Morsier syndrome, is a rare congenital condition, characterized by two of the classic triad features: midline brain abnormalities, optic nerve hypoplasia (ONH) and pituitary endocrine dysfunction. We report 5 children with SOD, originally referred to be evaluated due to short stature, who also presented bilateral optic nerve hypoplasia, nystagmus and development delay. In 4 of the patients, we identified neuroimaging abnormalities of the hypothalamo-pituitary axis such as anterior pituitary hypoplasia (3/5), ectopic posterior pituitary (4/5), thin or absent stalk (3/5) and empty sella (1/5). We also encountered diverse pituitary deficiencies: growth hormone (3/5), adrenocorticotropic hormone (3/5), thyroid-stimulating hormone (2/5) and antidiuretic hormone (1/5). Only one child presented intact pituitary function and anatomy. Although rare, SOD is an important cause of congenital hypopituitarism and it should be considered in children with optic nerve hypoplasia or midline brain abnormalities for early diagnosis and treatment. Key words: septo-optic dysplasia, optic nerve/abnormalities, hypopituitarism. Displasia septo-óptica resumoA displasia septo-óptica (DSO, síndrome de Morsier) é uma condição congênita rara definida por dois critérios da tríade: defeitos de linha média, hipoplasia de nervo óptico e insuficiência hipotálamo-hipofisária. Descrevemos 5 casos de DSO, encaminhados por baixa estatura, com hipoplasia dos nervos ópticos, nistagmo e atraso global do desenvolvimento. Destes, 4 possuem alteração na ressonância magnética de sela túrcica e insuficiência hipotálamo-hipofisária, tendo sido observada adeno-hipófise hipoplásica (3/5), neuro-hipófise ectópica (4/5), haste afilada/ausente (3/5) e sela vazia (1/5), além de déficit dos eixos somatotrófico (3/5), adrenocorticotrófico (3/5), tireotrófico (2/5) e do hormônio antidiurético (1/5). Apenas um paciente não apresenta alteração anatômica ou funcional do eixo hipotálamo-hipofisário. Embora rara, a DSO é causa importante de hipopituitarismo congênito, devendo ser considerada em crianças com hipoplasia de nervo óptico ou defeito de linha média para seu diagnóstico e tratamento precoces, evitando seqüelas graves. Palavras-chave: displasia septo-óptica, nervo óptico/anormalidades., hipopituitarismo.
