Phthalates, as other endocrine disrupting chemicals (EDCs), may alter the homeostasis and the action of hormones and signaling molecules, causing adverse health outcomes. This is true especially for infants, who are both more exposed and sensitive to their effects. Phthalates are particularly harmful when the exposure occurs during certain critical temporal windows of the development, such as the prenatal and the early postnatal phases. Phthalates may also interfere with the neuroendocrine systems (e.g., thyroid hormone signaling or metabolism), causing disruption of neuronal differentiation and maturation, increasing the risk of behavioral and cognitive disorders (ADHD and autistic behaviors, reduced mental, psychomotor, and IQ development, and emotional problems). Despite more studies being needed to better understand the role of these substances, plenty of evidence suggests the impact of phthalates on the neuroendocrine system development and function. This review aims to update the knowledge on the neuroendocrine consequences of neonatal and perinatal exposure to phthalates.

Background Gender incongruence (GI) is a term used to describe a marked and persistent incompatibility between the sex assigned at birth (SAAB) and the experienced gender. Some persons presenting with GI experience a severe psychological distress defined as gender dysphoria (GD).. Although the prevalence of GI is probably underestimated, recently a great increase in numbers of transgender and gender diverse (TGD) youths presenting at the gender clinics has been registered. After a careful multidisciplinary evaluation and upon acquisition of informed consent from the youth and the legal guardian(s), puberty suppression can be started in TGD youths, followed by the addition of gender affirming hormones (GAH) by the age of 16 years. Although Italian specific guidelines are available, their application is often complex because of (among other reasons) lack of specialized centers and healthcare professional with experience in the field and the regional differences within the Italian healthcare system. Main body To investigate the care offered to TGD youths across Italy, we proposed a survey of 20 questions to the directors of the 32 Italian Centers of pediatric endocrinology participating to the Study Group on Growth and Puberty of the Italian Society of Pediatric Endocrinology (ISPED). Eighteen pediatric endocrinologists representative of 16 different centers belonging to 11 different regions responded to the survey. In the large majority of centers TGD youths are taken in charge between the age of 12 and 18 years and at least three healthcare professional are involved. Most of Italian pediatric endocrinologists follow only a very limited number of TGD youths and reference centers for TGD youths are lacking. Conclusion There is an urgent need for gender clinics (homogeneously distributed on the national territory) where TGD youths can access high standard care.

Background Hypospadias is one of the most common congenital abnormalities in male newborn. There is no universal approach to hypospadias surgical repair, with more than 300 corrective procedures described in current literature. The reoperation rate within 6–12 months of the initial surgery is most frequently used as an outcome measure. These short-term outcomes may not reflect those encountered in adolescence and adult life. This study aims to identify the long-term cosmetic, functional and psychosexual outcomes. Methods Medical records of boys who had undergone surgical repair of hypospadias by a single surgical team led by the same surgeon at a single centre between August 2001 and December 2017 were reviewed. Families were contacted by telephone and invited to participate. Surgical outcome was assessed by combination of clinical examination, a life-related interview and 3 validated questionnaires (the Penile Perception Score-PPS, the Hypospadias Objective Score Evaluation-HOSE, the International Index of Erectile Function-5-IIEF5). Outcomes were compared according to age, severity of hypospadias, and respondent (child, parent and surgeon). Results 187 children and their families agreed to participate in the study. 46 patients (24.6%) presented at least one complication after the repair, with a median elapsed time of 11.5 months (6.5–22.5). Longitudinal differences in surgical corrective procedures ( p  < 0.01), clinical approach (p < 0.01), hospitalisation after surgery (p < 0.01) were found. Cosmetic data from the PPS were similar among children and parents, with no significant differences in child’s age or the type of hypospadias: 83% of children and 87% of parents were satisfied with the cosmetic result. A significant difference in functional outcome related to the type of hypospadias was reflected responses to HOSE amongst all groups of respondents: children ( p  < 0.001), parents (p=0.02) and surgeon ( p  < 0.01). The child’s HOSE total score was consistently lower than the surgeon (p < 0.01). The HOSE satisfaction rate on functional outcome was 89% for child and 92% for parent respondents. Conclusion Surgeons and clinicians should be cognizant of the long-term outcomes following hypospadias surgical repair and this should be reflected in a demand for a standardised approach to repair and follow-up.

Central nervous system (CNS) neoplasms are the most common solid tumors diagnosed in children. CNS tumors represent the leading cause of cancer death and cancer-related morbidity for children less than 20 years of age, although there has been a moderate increase in survival rates over the past several decades. The average survival at 5 years now nearly reaches 75%, and for some, non-malignant histology approximates 97% at 20 years from diagnosis. Neurological, cognitive, and neuropsychological deficits are the most disabling long-term effects of brain tumors in children. Childhood is a time of extreme brain sensitivity and the time of life in which most brain development occurs. Thus, the long-term toxicities that children treated for CNS tumors experience can affect multiple developmental domains and day-to-day functioning, ultimately leading to a poor quality of survival (QoS). We reviewed literature focusing on the risk factors for cognitive and neuropsychological impairment in pediatric patients treated for brain tumors with the aim of better understanding who is at major risk and what the best strategies for monitoring these patients are.

Causes of blackwater fever, a complication of malaria treatment, are not completely clear, and immune mechanisms might be involved. Clinical management is not standardized. We describe an episode of blackwater fever in a nonimmune 12-year-old girl in Italy who was treated with steroids, resulting in a rapid clinical resolution.

Kawasaki disease (KD) is a febrile systemic vasculitis of unknown etiology and the main cause of acquired heart disease among children in the developed world. To date, abdominal involvement at presentation is not recognized as a risk factor for a more severe form of the disease. To evaluate whether presenting abdominal manifestations identify a group at major risk for Intravenous immunoglobulin (IVIG)-resistance and coronary lesions. Retrospective study of KD patients diagnosed between 2000 and 2015 in 13 pediatric units in Italy. Patients were divided into 2 groups according to the presence or absence of abdominal manifestations at onset. We compared their demographic and clinical data, IVIG-responsiveness, coronary ectasia/aneurysms, laboratory findings from the acute and subacute phases. 302 patients (181 boys) were enrolled: 106 patients with, and 196 patients without presenting abdominal features. Seasonality was different between the groups (p = 0.034). Patients with abdominal manifestations were younger (p = 0.006) and more frequently underwent delayed treatment (p = 0.014). In the acute phase, patients with abdominal presentation had higher platelet counts (PLT) (p = 0.042) and lower albuminemia (p = 0.009), while, in the subacute phase, they had higher white blood cell counts (WBC) and PLT (p = 0.002 and p < 0.005, respectively) and lower red blood cell counts (RBC) and hemoglobin (Hb) (p = 0.031 and p 0.009). Moreover, the above mentioned group was more likely to be IVIG-resistant (p < 0.005) and have coronary aneurysms (p = 0.007). In the multivariate analysis, presenting abdominal manifestations, age younger than 6 months, IVIG- resistance, delayed treatment and albumin concentration in the acute phase were independent risk factors for coronary aneurysms (respectively p<0.005, <0.005, = 0.005 and 0.009). This is the first multicenter report demonstrating that presenting gastrointestinal features in KD identify patients at higher risk for IVIG-resistance and for the development of coronary aneurysms in a predominantly Caucasian population. 8/20014/O/OssN.

Background: Digital devices (DDs) are increasingly present in early childhood, with screen exposure beginning as early as infancy. Despite international and national guidelines discouraging digital media use before age two, many children are exposed to screens far earlier, often mediated by parents and caregivers. Excessive or unregulated screen use has been linked to adverse neurodevelopmental, emotional, and physical outcomes. Objective: This study aims to assess the knowledge, attitudes, and educational needs of primary care pediatricians (PCPs) regarding digital education (DE) and DD use in preschool-aged children (0–6 years) in two provinces of Northern Italy. Methods: A cross-sectional survey was distributed to all 165 PCPs in the Modena and Reggio Emilia provinces between December 2024 and January 2025. The 17-item questionnaire explored PCPs’ knowledge of guidelines, awareness of DD-related risks, current counseling practices, and training needs. Results: Of the 165 contacted PCPs, 93 (56%) completed the survey. While 77% were aware of Italian Pediatric Society recommendations, only 56% correctly identified age two as the threshold for total screen avoidance. 87% of PCPs recognized the risks of excessive DD use, particularly its cognitive, behavioral, and physical consequences. Nearly all participants (95%) reported discussing DE during clinical visits, and 96% expressed a desire for further training. Conclusions: PCPs show strong engagement in promoting healthy digital habits but lack specific knowledge of current recommendations. Structured tools such as digital health check-ups and targeted training programs are needed to strengthen pediatricians’ roles in digital health education and support parental guidance.

Being overweight or obese is one of the most common reasons that children and adolescents are teased at school. We carried out a study in order to investigate: i) the relation between weight status and school bullying and ii) the relation between weight status categories and types of victimization and bullying in an outpatient sample of Italian children and adolescents with different degrees of overweight from minimal overweight up to severe obesity. Nine-hundred-forty-seven outpatient children and adolescents (age range 6.0-14.0 years) were recruited in 14 hospitals distributed over the country of Italy. The participants were classified as normal-weight (N = 129), overweight (N = 126), moderately obese (N = 568), and severely obese (N = 124). The nature and extent of verbal, physical and relational bullying and victimization were assessed with an adapted version of the revised Olweus bully-victim questionnaire. Each participant was coded as bully, victim, bully-victim, or not involved. Normal-weight and overweight participants were less involved in bullying than obese participants; severely obese males were more involved in the double role of bully and victim. Severely obese children and adolescents suffered not only from verbal victimization but also from physical victimization and exclusion from group activities. Weight status categories were not directly related to bullying behaviour; however severely obese males perpetrated more bullying behaviour compared to severely obese females. Obesity and bullying among children and adolescents are of ongoing concern worldwide and may be closely related. Common strategies of intervention are needed to cope with these two social health challenges.

Type 1 diabetes (T1D) is the most common paediatric endocrine disease, and its frequency has been found to increase worldwide. Similar to all conditions associated with poorly regulated glucose metabolism, T1D carries an increased risk of infection. Consequently, careful compliance by T1D children with schedules officially approved for child immunization is strongly recommended. However, because patients with T1D show persistent and profound limitations in immune function, vaccines may evoke a less efficient immune response, with corresponding lower protection. Moreover, T1D is an autoimmune condition that develops in genetically susceptible individuals and some data regarding T1D triggering factors appear to indicate that infections, mainly those due to viruses, play a major role. Accordingly, the use of viral live attenuated vaccines is being debated. In this narrative review, we discussed the most effective and safe use of vaccines in patients at risk of or with overt T1D. Literature analysis showed that several problems related to the use of vaccines in children with T1D have not been completely resolved. There are few studies regarding the immunogenicity and efficacy of vaccines in T1D children, and the need for different immunization schedules has not been precisely established. Fortunately, the previous presumed relationship between vaccine administration and T1D appears to have been debunked, though some doubts regarding rotavirus vaccines remain. Further studies are needed to completely resolve the problems related to vaccine administration in T1D patients. In the meantime, the use of vaccines remains extensively recommended in children with this disease.

Background Extra-uterine growth restriction (EUGR) is a condition caused by the failure of very preterm infants to reach their potential growth during the NICU hospital stay. Despite improvements in nutritional supports, their growth pattern is still far from that expected. EUGR is now recognized as a major risk factor for long-term metabolic, anthropometric, and cognitive outcomes. Aim of our study was to evaluate anthropometric and metabolic outcome at peripubertal age in a population of ex-preterm VLBW infants and to detect the possible influence of EUGR on short stature. Methods Retrospective cohort study of children born in a single centre between 2005 and 2009 with VLBW (birth weight < 1500 g). Families were recruited by telephone. During the clinical evaluation at peri-pubertal age, we measured height, head circumference, weight, and Body Mass Index (BMI), and clinical laboratory tests. Data were analyzed using SPSSv10.0 (SPSS Inc., Chicago, IL, USA). The Mann-Whitney U test was used for inter-group comparisons of continuous variables, and the Spearman test was used for correlations between variables. For intra-group comparisons, the paired t-test was used. Differences among three or more groups were assessed using the non-parametric Kruskal–Wallis test. Results We enrolled 78 patients, 21 (27%) born Small for Gestational Age (SGA). Comparing anthropometrics at discharge with those at birth, a significant impairment was found in the whole population for weight, length, and head circumference SDS ( p  < 0.001). EUGR was detected in all the children born SGA and in 50% of the children born AGA. At peripubertal age four subjects presented with short stature (5.19%): all were EUGR, and three were on rhGH treatment. Patients who developed asymmetric EUGR had lower HDL cholesterol (p:0.049) and higher fasting blood glucose value at peripubertal age, compared to our population (p:0.049). Conclusion Our data confirm SGA infants at birth develop EUGR at discharge and are associated with metabolic development noted at the peripubertal age. Recording anthropometric parameters during the NICU hospital stay is crucial, as they are related to weight, BMI, and metabolic risk factors at peripubertal age. Trial registration Local Ethics Committee approved the protocol (AVEN CE N. 124/2018).
