A Novel De novo Heterozygous Mutation in the SON Gene Associated with Septo-optic Dysplasia: A New Phenotype.

Septo-optic dysplasia (SOD) syndrome is a rare congenital disorder characterized by a classic triad of optic nerve/chiasm hypoplasia, agenesis of septum pellucidum and corpus callosum, and hypoplasia of the hypothalamic-pituitary axis.Herein, we report the clinical case of 2-year-old boy presenting with psychomotor delay, nystagmus, congenital hypothyroidism, and a clinically relevant growth delay. The neuroradiological examination showed partial segmental agenesis of the corpus callosum, agenesis of the septum pellucidum, optic nerve hypoplasia, and a small pituitary gland with a small median pituitary stalk. A whole-exome sequencing analysis detected a novel heterozygous de novo variant c.1069_1070delAG in SON, predicted as likely pathogenic.To date, SON pathogenic variants have been described as responsible for Zhu-Tokita-Takenouchi-Kim (ZTTK) syndrome, a multisystemic neurodevelopmental disorder mainly characterized by intellectual disability, facial dysmorphisms, visual abnormalities, brain malformations, feeding difficulties, and growth delay. The herein described case is the first recognized clinic-radiological occurrence of SOD syndrome with hypothalamic-pituitary dysfunction in a patient carrying a SON gene variant, considered responsible of ZTTK syndrome, suggesting a possible relationship between SOD and SON gene alterations, never described so far, making the search for SON gene mutations advisable in patients with SOD.

1000 Days: The "WeCare Generation" Program-The Ultimate Model for Improving Human Mental Health and Economics: The Study Protocol.

INTRODUCTION: The COVID-19 pandemic stressed the necessity of a new resilience of the human population and health system. The "WeCare Generation" program is a new proposal of territorial intervention, with a new paradigm, on the diseases of the human body and mind. BACKGROUND: In recent decades, the independent strands of investigation on brain plasticity and early trauma consequences have demonstrated that traumatic experiences in the period from pregnancy to the age of 3 years have an enormous impact on an individual's future development, and both physical and mental health. Research shows that adverse child experiences (ACEs) are associated with a strong risk of conditions such as: harmful alcohol use, smoking, illicit drug use, high body-mass index, depression, anxiety, interpersonal violence, cancer, type 2 diabetes, cardiovascular diseases, stroke respiratory diseases and, as a consequence, to a high financial cost in Italy and also across Europe (1-9% GDP) and the USA (total annual costs estimated to be USD 581 billion in Europe and USD 748 billion in North America). All this suggests that an early intervention on that traumatized-slice of population leads to multiplied savings. METHODS: A multi-center, randomized, controlled trial was designed. The parents of the future neonatal population (from pregnancy to delivery) with trauma will be enrolled, and randomized to treatment, or control arm. The article describes in detail how the primary outpoint (cost to the national health system), and some secondary outpoints, will be collected. DISCUSSION: An overall rate of return on investment (ROI) statistically significant 13.0% per annum with an associated benefit/cost ratio (BCR) of 6.3 is expected as the primary outcome of the "WeCare Generation" program. Our proposed model predicts a new medical paradigm aiming to empower new generations, with a strong return on economy and health.

High levels of physical activity in female adolescents with anorexia nervosa: medical and psychopathological correlates.

PURPOSE: While overexercise is commonly described in patients who experience anorexia nervosa (AN), it represents a condition still underestimated, especially in the paediatric population. METHOD: The present study aims at assessing the possible associations between levels of physical activity (PA) and clinical features, endocrinological data and psychopathological traits in a sample of 244 female adolescents hospitalised for AN subdivided into two groups according to PA levels (high PA vs. no/low PA). The two groups were compared through multivariate analyses, while multiple regression analysis was conducted to determine whether physical activity predict specific outcomes. RESULTS: No significant differences were found between the two groups in terms of last Body Mass Index (BMI) before illness, BMI at admission and disease duration, while a difference emerged in delta BMI(rapidity of weight loss), significantly higher in high-PA group (p = 0.021). Significant differences were observed in Free triiodothyronine- (p < 0.001), Free thyroxine (p = 0.046), Follicle-stimulating hormone (p = 0.019), Luteinising hormone (p = 0.002) levels, with values remarkably lower in high-PA group. Concerning psychopathological scales, the high-PA group showed worst Children's Global Assessment Scale (CGAS) scores (p = 0.035). Regression analyses revealed that higher PA predicts higher delta BMI (p = 0.021), presence of amenorrhea (p = 0.003), lower heart rate (p = 0.012), lower thyroid (Free triiodothyronine p < 0.001, Free thyroxine p = 0.029) and gynaecological hormones' levels (Follicle-stimulating hormone p = 0.023, Luteinising hormone p = 0.003, 17-Beta estradiol p = 0.041). Concerning psychiatric measures, HPA predicts worst scores at CGAS (p = 0.019), and at scales for evaluation of alexithymia (p = 0.028) and depression (p = 0.004). CONCLUSIONS: Results suggest that high levels of physical activity in acute AN associate with worst clinical conditions at admission, especially in terms of endocrinological and medical features. LEVEL OF EVIDENCE: Level III.

Renal dysfunctions and clinical correlates in adolescents with restrictive anorexia nervosa.

BACKGROUND AND AIMS: The alteration of kidney function in adolescents with anorexia nervosa (AN) is a frequent, but still poorly investigated, consequence of AN. In this study, we analyzed glomerular filtration rate with the Cockroft-Gault formula in a group of 148 adolescents with Anorexia Nervosa and correlated it to clinical and biochemical data collected at admission. METHODS: A retrospective study was conducted on 148 patients hospitalized from 2016 to 2019 for severe malnutrition due to restrictive AN. We measured glomerular filtration rate and correlated it with the patients' anamnestic history, nutritional status and biochemical data. RESULTS: For the 148 AN patients, 40 (27%) resulted at admission at stage 1 of kidney damage (GFR>90 mL/min), 88 patients (59%) at stage 2 (GFR 89-60 mL/min), 17 patients (11%) at stage 3A (GFR 59-45 mL/min) and 3 patients (2%) at stage 3B (GFR 44-30 mL/min). Results outlined a correlation between the entity of kidney damage and BMI at admission and before illness onset, but not with the rapidity and entity of weight loss. Further, more severe renal damages corresponded to major biochemical and hormonal alterations. CONCLUSIONS: Results of our study confirm that kidney damage is a frequent condition in adolescents with restrictive-type AN and support making kidney functionality tests part of routine care in patients with AN.

Psychopathological traits of adolescents with functional hypothalamic amenorrhea: a comparison with anorexia nervosa.

BACKGROUND: Functional hypothalamic amenorrhea (FHA) is a form of anovulation, due to the suppression of hypothalamic-pituitary-ovarian axis, not related to identifiable organic causes. Like adolescents with anorexia nervosa (AN), subjects with FHA show dysfunctional attitudes, low self-esteem, depressive mood, anxiety and inability to cope with daily stress. The aim of the study is to examine similarities and differences between FHA and AN in terms of clinical profiles and psychological variables. METHODS: 21 adolescents with FHA, 21 adolescents with anorexia nervosa, and 21 healthy adolescents were included in the study. All the teenagers completed a battery of self-administered psychological tests for the detection of behaviors and symptoms attributable to the presence of an eating disorder (EDI-2), depression (CDI), and alexithymia (TAS-20). RESULTS: Different from healthy controls, subjects with FHA and with AN shared common psychopathological aspects, such as maturity issues, social insecurity and introversion, a tendency to depression, excessive concerns with dieting, and fear of gaining weight. Nevertheless, adolescents with AN presented a more profound psychopathological disorder as observed at test comparisons with subjects with FHA. CONCLUSIONS: Results show a clinical spectrum that includes AN and FHA and suggest the necessity to treat FHA with a multidisciplinary approach for both organic and psychological aspects.

Heart rate variability in adolescents with functional hypothalamic amenorrhea and anorexia nervosa.

Aim of this study consisted in assessing the 24-h heart rate variability (HRV), a measure of autonomic nervous system (ANS) imbalance, in 21 adolescents with functional hypothalamic amenorrhea (FHA, 11 normogonadotropic, N-FHA, and 10 hypogonadotropic, Hy-FHA) compared to 21 patients with anorexia nervosa (AN) and 21 controls. As expected, subjects with AN showed a significant dysregulation in multiple HRV parameters, while Hy-FHA patients presented with a dysregulation in a few domains (SDNN, HFr), which was not present in girls with N-FHA, who showed values largely similar to controls. FHA might represent part of the AN biological spectrum, and a link between these two conditions might exist, possibly related to the degree of psychological and/or hormonal dysfunction.

Endocrine profiles and neuropsychologic correlates of functional hypothalamic amenorrhea in adolescents.

OBJECTIVE: To determine trigger factors and neuropsychologic correlates of functional hypothalamic amenorrhea (FHA) in adolescence and to evaluate the correlations with the endocrine-metabolic profile. DESIGN: Cross-sectional comparison of adolescents with FHA and eumenorrheic controls SETTING: Academic medical institution PATIENT(S): Twenty adolescent girls with FHA (aged <18 years) and 20 normal cycling girls INTERVENTION(S): All subjects underwent endocrine-gynecologic (hormone) and neuropsychiatric (tests and interview) investigations. A separate semistructured interview was also used to investigate parents. MAIN OUTCOME MEASURE(S): Gonadotropins, leptin, prolactin, androgens, estrogens, cortisol, carrier proteins (SHBG, insulin-like growth factor-binding protein 1), and metabolic parameters (insulin, insulin-like growth factor 1, thyroid hormones) were assayed in FHA and control subjects. All girls were evaluated using a test for depression, a test for disordered eating, and a psychodynamic semistructured interview. RESULT(S): Adolescents with FHA showed a particular susceptibility to common life events, restrictive disordered eating, depressive traits, and psychosomatic disorders. The endocrine-metabolic profile was strictly correlated to the severity of the psychopathology. CONCLUSION(S): Functional hypothalamic amenorrhea in adolescence is due to a particular neuropsychologic vulnerability to stress, probably related to familial relationship styles, expressed by a proportional endocrine impairment.
