Background: Septo-optic dysplasia (SOD) is a rare congenital anomaly, clinically heterogeneous, combining optic nerve and pituitary gland hypoplasia, midline abnormalities of the brain, including absence of the corpus callosum and septum pellucidum. The diagnosis is made when two or more features of the classic triad are present. HESX1, SOX2, SOX3, FGF8, FGFR1, PROKR1, SHH, are implicated in the etiology of SOD.Objective and hypotheses: Description of a ...

Background: Loss-of-function mutations in the imprinted gene MKRN3 represent the most common known genetic defects associated with central precocious puberty (CPP). The penetrance of these mutations remains to be established. To date, all reported individuals with MKRN3 mutations were already in puberty or postpubertal and were identified retrospectively.Objective and hypotheses: To report the first case of a prepubertal child with an MKRN3 muta...

Background: Approximately 15 million children are born preterm worldwide yearly.Objective and hypotheses: To evaluate spontaneous growth during the first 8 years of life.Hypotheses: Preterm born children have spontaneous recovery of weight and height in the first 8 years of life.Method: Measurements at birth, 6, 12 and 24 months of corrected age and at recall [6.4±0.5 years (5.2–8.0)]. Weight, lengt...

Background: In the past decades Brazil has experienced a nutritional transition process characterised by a significant reduction in malnutrition and progressive increase in overweight and obesity. Nutritional education and precocious interventions are useful strategies to combat excess weight in childhood and adolescence. According to the World Health Organization (WHO), there were more than 40 million children overweight in the world in 2011. In Brazil, the prevalence of exce...

Background: We report clinical and molecular cytogenetic characterization of a 13-year-7-month-old boy with a Sotos-like phenotype and de novo NFIX deletions and review the literature.Result: A whole exome sequencing revealed in the present patient with unique clinical phenotypes a de novo frameshift mutation c.570-573delATCA (p.S191Ifs*19) in NFIX gene in 19p13.2.Discussion: The p...

Background: Osteogenesis imperfecta (OI) is characterized by abnormal bone development with low bone mass and increased bone fragility. Dominant mutations affect synthesis & structure of type 1pro-collagen. Recessive mutations affect post-translational processing or tracking of type 1 pro-collagen. OI may be associated with dentinogenesis imperfecta type 1, for both primary and permanent dentition, particularly primary, manifested as tooth discoloration, reduced enamel thi...

Background: Childhood onset (CO) hypogonadotrophic hypogonadism (HH), congenital or acquired after midline tumours and their treatment, is reported to have significantly poorer outcomes, in terms of adult spermatogenesis induction and duration of treatment to conception, compared with HH of post pubertal onset. A mixed cohort (youngest aged 26 years) reported median time to conception of 28 months.1 Use of hCG and FSH in adolescence is reported to result in spermato...

Background: Intra uterine growth retardation (IUGR) is well recognized to result in infants born small for gestational age (SGA). Early morbidity is followed by increased lifetime risks for health problems, particularly in the 10% of IUGR infants who fail to catch up. Risks include metabolic syndrome with obesity, insulin resistance, abnormal glucose metabolism, hypertension, dyslipidaemia, T2DM. Rapid weight gain in infancy is associated with increased incidence of later obes...

A 12 year old boy sustained a severe head injury by a passing car whilst crossing the road. Injuries were confined to massive basal skull fracture, right sided blindness, acute onset diabetes insipidus, extradural and subdural bleeding requiring surgical decompression. Pre-operative physical examination revealed a healthy looking boy, height 60th centile for age, Tanner stage III puberty, 10 ml testes bilaterally. MR head demonstrated apparent pituitary stalk transection and r...

Adrenal insufficiency of any cause results in major morbidity and increased lifetime risk for adrenal crisis and potential mortality. A majority of those affected by disorders of either congenital or acquired origin have deficiencies of both glucocorticoid and mineralocorticoid. Preferred replacement treatment for infants, children and adolescents with growth potential is considered to be with hydrocortisone and fludrocortisone.Both medications are advoc...
