The impact of IGF-I, puberty and obesity on early retinopathy in children: a cross-sectional study
Abstract Background Childhood obesity has been correlated with coronary heart disease, but the correlation with microvascular disease remains unclear. The retinal microcirculation is affected early in the process of atherosclerosis and it offers the opportunity to indirectly study the effects of obesity on small brain vessels. Insulin-like growth factor 1 (IGF-I) is involved in angiogenesis and it has a crucial role in retinal vascularization. Methods A single-centre cross-sectional study was performed in 268 children and adolescents (116 males; mean age 13.03 ± 1.9 years,) with overweight/obesity, in order to identify risk factors for early retinopathy. Results Nine patients (3.3%) showed signs of retinopathy, defined as arteriovenous crossings and/or papilledema. Body mass index and fat mass, analysed by Dual X-ray Absorptiometry, were not different in patients with or without retinopathy. Patients with retinopathy were pubertal and showed higher waist circumference (107.78 ± 15.83 versus 99.46 ± 10.85 cm; p: 0.027), waist circumference/height ratio (0.66 ± 0.07 versus 0.62 ± 0.05; p: 0.04) and IGF-I SDS (0.03 ± 1.3 versus − 0.66 ± 0.9; p: 0.04). Multivariate analysis (after correction for sex, age, family history of type 2 diabetes mellitus, obesity, cardiovascular disease, hypertension and dyslipidaemia) showed that waist circumference/height ratio and IGF-I SDS were the only variables independently correlated with the presence of retinopathy. Conclusions Retinal vascular changes may become evident as an early complication of overweight and obesity, even during childhood and adolescence. Relatively high levels of IGF-I during this phase may act as an additional risk factor for microvascular damage. The screening for retinopathy should be proposed to all children and adolescents with overweight/obesity
Lipoid congenital adrenal hyperplasia by steroidogenic acute regulatory protein (STAR) gene mutation in an Italian infant: an uncommon cause of adrenal insufficiency
Abstract Background Lipoid congenital adrenal hyperplasia (CAH) (OMIM n. 201710) is the most severe form of congenital adrenal hyperplasia. It is characterized by severe adrenal and gonadal steroidogenesis impairment due to a defect in the conversion of cholesterol to pregnenolone. Affected infants experience salt loss, but glucocorticoid and mineralocorticoid replacement therapy enables long-term survival. Classic lipoid congenital adrenal hyperplasia is relatively common in Japan and Korea but extremely rare in Caucasian populations. Case presentation A female infant of Italian origin came to our attention in late infancy with a clinical picture of acute adrenal insufficiency. The study of the STAR gene revealed two genomic variants c.562CÂ >Â T and c.577CÂ >Â T in compound heterozygosity. At the protein level, the two mutations determine the p.Arg188Cys variant (rs104894090) and the p.Arg193Ter variant (rs387907235), respectively. Sanger sequencing was used to confirm the identified variants and to perform familial study. The mother carried the p.Arg188Cys variant, while the father carried the p.Arg193Ter variant. Conclusion To our knowledge this is the second case of classic lipoid congenital adrenal hyperplasia reported in the Italian population. STAR mutations resulting in lipoid congenital adrenal hyperplasia should be considered all over the world in the differential diagnosis of newborn babies and infants with primary adrenal insufficiency
Spinal cord ultrasonography of the newborn
Ultrasound represents the first-line survey for the assessment of spinal cord development abnormalities. In fact, within 6Â months of life, the non-ossification of neuronal arcs provides an excellent acoustic window that allows a detailed depiction of the spinal canal, its content and of the surrounding soft tissues. Nevertheless, an accurate ultrasound examination requires a complete knowledge of the anatomy, the condition of normality, the frequent anatomical variants and the main pathologies involved. This review is intended to briefly summarize the US technique, the main clinical indication and the key notions that could help to properly perform this type of ultrasound examination
Management of Childhood-onset Craniopharyngioma in Italy: A Multicenter, 7-Year Follow-up Study of 145 Patients
Context Nationwide data on children diagnosed with craniopharyngioma (CP) are not available in Italy. Objective This work aimed to identify patients' characteristics, type of surgical approach, complications and recurrences, number of pituitary deficits, and number of patients starting growth hormone (GH) treatment. Methods A retrospective multicenter collection took place of 145 patients aged 0 to 18 years who underwent surgery for CP between 2000 and 2018, and followed up in 17 Italian centers of pediatric endocrinology. Results Age at diagnosis was 8.4 +/- 4.1 years. Duration of symptoms was 10.8 +/- 12.5 months and headache was most frequent (54%), followed by impaired growth (48%) and visual disturbances (44%). Most lesions were suprasellar (85%), and histology was adamantinomatous in all cases but two. Surgical approach was transcranial (TC) in 67.5% of cases and transsphenoidal (TS) in 31.%. The TC approach was prevalent in all age groups. Postsurgery complications occurred in 53% of cases, with water-electrolyte disturbances most frequent. Radiotherapy was used in 39% of cases. All patients but one presented with at least one hormone pituitary deficiency, with thyrotropin deficiency most frequent (98.3%), followed by adrenocorticotropin (96.8%), arginine vasopressin (91.1%), and GH (77.4%). Body mass index (BMI) significantly increased over time. A hypothalamic disturbance was present in 55% of cases. GH therapy was started during follow-up in 112 patients at a mean age of 10.6 years, and 54 developed a recurrence or regrowth of the residual lesion. Conclusion CP is often diagnosed late in Italy, with TC more frequent than the TS surgical approach. Postsurgery complications were not rare, and hypopituitarism developed almost in all cases. BMI shows a tendency to increase overtime
Lipoid congenital adrenal hyperplasia by steroidogenic acute regulatory protein (STAR) gene mutation in an Italian infant: an uncommon cause of adrenal insufficiency
Management of childhood-onset craniopharyngioma in Italy: A multicenter seven year follow-up study of 145 patients
Context: Nationwide data on children diagnosed with craniopharyngioma (CP) are not available in Italy. Objective: Identify patients' characteristics, type of surgical approach, complications and recurrences, number of pituitary deficits and number of patients starting GH treatment. Methods: Retrospective multicenter collection of 145 patients aged 0-18 years underwenting surgery for CP between 2000-2018, followed-up in 17 Italian centers of Pediatric Endocrinology. Results: Age at diagnosis was 8.4±4.1 years. Duration of symptoms was 10.8±12.5 months and headache was most frequent (54%), followed by impaired growth (48%) and visual disturbances (44%). Most lesions were suprasellar (85%) and histology was adamantinomatous in all cases but two. Surgical approach was transcranic (TC) in 67.5% of cases and transphenoidal (TS) in 31.%. TC approach was prevalent in all age groups. Post-surgery complications occurred in 53% of cases with water-electrolyte disturbances most frequent. Radiotherapy was used in 39% of cases. All patients but one presented at least one hormone pituitary deficiency, with TSH deficit as most frequent (98.3%), followed by ACTH (96.8%), AVP (91.1%) and GH (77.4%). BMI significantly increased over time. A hypothalamic disturbance was present in 55% of cases. GH therapy was started during follow-up in 112 patients at a mean age of 10.6 years and 54 developed a recurrence or regrowth of the residual lesion. Conclusions: CP is often diagnosed late also in Italy with TC more frequent than TS surgical approach. Post-surgery complications were not rare and hypopituitarism developed almost in all cases. BMI shows a tendency to increase overtime
