Abstract Background and objective Drug Hypersensitivity Reactions (DHRs) are considered adverse effects of medications that resemble allergy symptoms. The reported positive clinical history of pediatric drug reactions is about 10%, however, after allergy investigations, only a small percent is confirmed as hypersensitivity. The aim of this study was to analyze the clinical history, allergy work-up results and sensitization profile of children and adolescents referred to our Allergy Unit for suspected DHRs. Methods The study evaluated data related to a group of children with a positive history of drug reactions during a two-year period. The allergy work-up consisted of in vivo and in vitro tests, in accordance with the recommendations of the ENDA/EAACI guidelines. Results Data from a group of 637 patients [348 M (54.6%); 289 F (45.4%)] were retrospectively analyzed. Beta lactams (BLs) were the most common drugs involved in the reported clinical history, followed by non-steroidal anti-inflammatory drugs (NSAIDs). Severe cutaneous adverse reactions (SCARs) were most frequently observed during BL treatment. The confirmation of BL hypersensitivity was higher for immediate reactions (IRs) [9.4%; 5.1% through positive skin tests (STs) and 5.5% through drug provocation test (DPT)] compared to non-immediate reactions (non-IRs) (8.1%; 2.2% through STs and 6.2% through DPT). A higher number of positive results was obtained for BLs and macrolides when the tests were performed within 12 months after the index reaction (p

Abstract Objective Rare and complex epilepsies encompass a diverse range of disorders characterized by seizures. We aimed to establish a consensus on key issues related to these conditions through collaboration among experienced neurologists, neuropediatricians, and patient advocacy representatives. Methods Employing a modified Delphi method, a scientific board comprising 20 physicians and 4 patient advocacy representatives synthesized existing literature with their expertise to formulate statements on contentious topics. A final 32‐member expert panel, representing diverse regions of Italy, validated these statements through a two‐round voting process, with consensus defined as an average score ≥7. Results Sixteen statements reached a consensus, emphasizing the necessity for epidemiological studies to ascertain the true prevalence of rare epilepsies. Etiology emerged as a crucial factor influencing therapeutic strategies and outcome prediction, with particular concern regarding prolonged and tonic–clonic seizures. The importance of early implementation of specific drugs and non‐pharmacological interventions in the treatment algorithm for developmental and epileptic encephalopathies (DEEs) was underscored. Multidisciplinary care involving experts with diverse skills was deemed essential, emphasizing non‐seizure outcomes in adolescence and adulthood. Significance This national consensus underscores the imperative for personalized, comprehensive, and multidisciplinary management of rare epilepsies/DEEs. It advocates for increased research, particularly in epidemiology and therapeutic approaches, to inform clinical decision‐making and healthcare policies, ultimately enhancing patients' outcomes. Plain Language Summary The modified Delphi method is broadly used to evaluate debated topics. In this work, we sought the consensus on integrated and social care in epilepsy management. Both representatives of high‐level epilepsy centers and patients' caregivers were directly involved.

Abstract Background Developmental and Epileptic Encephalopathies (DEEs) are defined by drug-resistant seizures and neurodevelopmental disorders. Over 50% of patients have a genetic cause. Studies have shown that patients with DEEs, regardless of genetic diagnosis, experience a central visual function disorder known as Cerebral (cortical) Visual Impairment (CVI). The prevalence of CVI in DEE patients is currently unknown. A quantitative synthesis of existing data on the prevalence rates of this condition would aid in understanding the magnitude of the problem, outlining future research, and suggesting the need for therapeutic strategies for early identification and prevention of the disorder. Methods The protocol followed the PRISMA-P statement for systematic review and meta-analysis protocols. The review will adhere to the JBI Manual for Evidence Synthesis (Systematic Reviews of Prevalence and Incidence) and use the CoCoPop framework to establish eligibility criteria. We will conduct a comprehensive search of several databases, including MEDLINE, EMBASE, Science Direct, Scopus, PsychINFO, Wiley, Highwire Press, and Cochrane Library of Systematic Reviews. Our primary focus will be determining the prevalence of cerebral visual impairments (Condition) in patients with developmental and epileptic encephalopathy (Population). To ensure clarity, we will provide a narrative summary of the risk of bias in the studies we include. The Cochrane Q statistic will be used to assess heterogeneity between studies. If the quantitative synthesis includes more than 10 studies, potential sources of heterogeneity will be investigated through subgroup and meta-regression analyses. Meta(bias)es analysis will also be performed. The quality of evidence for all outcomes will be evaluated using the Grading of Recommendations Assessment Development and Evaluation (GRADE) working group methodology. Discussion This protocol outlines a systematic review and meta-analysis to identify, collect, evaluate, and integrate epidemiological knowledge related to the prevalence of CVI in patients with DEEs. To the best of our knowledge, no other systematic review and meta-analysis has addressed this specific issue. The results will provide useful information for understanding the extent of the problem, outlining future research, and suggesting the need for early identification strategies. Systematic review registrations This Systematic Review Protocol was registered in PROSPERO (CRD42023448910).

Background: Fluorescein angiography (FA) has been a pivotal tool for studying the pathophysiology of retinopathy of prematurity (ROP) in vivo. We examined the course of ROP using FA to assess the predictive value of angiographic features. Methods: This is an observational retrospective cohort study of eyes screened for ROP with a binocular indirect ophthalmoscope and FA. RetCam fundus imaging and video digital fluorescein angiography were performed in the neonatal intensive care unit of Santa Maria Hospital of Perugia. The masked grading of the FA images was retrospectively conducted by two ROP expert ophthalmologists. Results: A total of 80 eyes of 40 patients were included for this study. Among the angiographic features evaluated, leakage, shunts, and tangles were predictive of the development of treatment-requiring ROP (p < 0.05). Conclusions: FA can add to our understanding of the evolution of vascular abnormalities in the course of ROP and can help predict which eyes will go on to treatment.

Aim To compare the need for intubation and mechanical ventilation after surfactant delivery between less invasive surfactant administration (LISA)-treated and intuba-tion-surfactant-extubation (IN-SURE)-treated premature infants with respiratory distress syndrome (RDS). Methods Retrospective registry-based cohort study enrolled 36 newborns admitted to the Neo-natal Intensive Care Unit of the “Santa Maria” Hospital of Terni between 2016 and 2023. As a primary outcome, the need for intubation and mechanical ventilation within 72 hours of life was followed, and major neonatal morbidities and death before discharge as the secondary outcome. Results The LISA group and the IN-SURE group included 13 and 23 newborns, respectively. Demographic features showed no significant differences between the two groups. The need for mechanical ventilation in the first 72 hours of life was similar in both groups (p>0.99). There were no significant differences in morbidities. Conclusion LISA and INSURE are equally effective modalities for surfactant administration for the treatment of RDS in preterm infants.

CDKL5 deficiency disorder (CDD) is a complex of clinical symptoms resulting from the presence of non-functional or absent CDKL5 protein, a serine–threonine kinase involved in neural maturation and synaptogenesis [...]

Thrombotic thrombocytopenic purpura (TTP) is a disorder of the blood-coagulation system, causing extensive microscopic clots to form in the small blood vessels throughout the body. TTP is quite a rare pathology in childhood, being more frequent among adults. Often it is hardly to distinguish from other haematological pathologies in children both for its uncommon incidence and for the presence of clinical forms that are heterogeneous and difficult to classify. We report the case of an 11-year-old girl suffering from TTP, in whom the study of metallo-protease ADAMST 13 showed a low value (

Recently, the anti-obesity medication fenfluramine (FFA) has been successfully repurposed, and it has received approval from various regulatory agencies for the treatment of seizures associated with Dravet syndrome and Lennox-Gastaut syndrome. The potential antiseizure effects of FFA were initially observed in patients with photosensitive epilepsy in the 1980s but it was not rigorously explored as a treatment option until 30 years later. This narrative review aims to provide an overview of the historical progression of FFA’s use, starting from initial clinical observations to preclinical studies and, ultimately, successful clinical trials in the field of epilepsy.Keywords: fenfluramine, seizures, Dravet syndrome, drug-resistant epilepsy, serotonin

Gemella haemolysans is a gram-positive coccus, and commensal of the upper respiratory tract and oral mucosa. In rare cases, it has been identified as an opportunistic pathogen in the development of endocarditis. Here, we describe a case of Gemella haemolysans endocarditis in a patient with bicuspid aortic valve. A 14-year-old male presented to our hospital with a 1-month history of intermittent fever. Gemella haemolysans was isolated from the patient’s blood cultures. Transesophageal echocardiography revealed severe aortic stenosis and a pseudoaneurysm of the mitral–aortic intervalvular fibrosa. The patient underwent aortic valve replacement with pseudoaneurysm of the mitral–aortic intervalvular fibrosa repair and remained symptom-free during follow-up. This case highlights the importance of considering atypical pathogens as causative agents of infective endocarditis.

BackgroundNFIA-related disorder (OMIM #613735) is an autosomal dominant neurodevelopmental disorder characterized by a variable degree of cognitive impairment and non-specific dysmorphic features. To date, fewer than thirty patients affected by this disorder have been described.MethodsOur study included three children with NFIA haploinsufficiency recruited from three medical genetics centers. Clinical presentations were recorded on a standardized case report form.ResultsAll patients presented a variable degree of intellectual disability. None of the individuals in our cohort had urinary tract malformations. Three novel mutations, c.344G>A, c.261T>G, and c.887_888del are reported here.ConclusionNFIA haploinsufficiency can be suspected through careful observation of specific dysmorphisms, including macrocephaly and craniofacial abnormalities. Instrumental tests such as MRI and renal ultrasound provide further diagnostic clues, while genetic testing can confirm the diagnosis.

BackgroundSleep and epilepsy are characterized by a bidirectional relationship. Indeed, epilepsy predisposes to the development of sleep disorders, while sleep deprivation may exacerbate epilepsy. In addition, antiseizure medication can disrupt normal sleep architecture. Therefore, adequate sleep hygiene could lead to improvement in seizure control. The present study aimed to evaluate the effect of melatonin on seizure frequency, EEG tracing, and sleep in children with focal idiopathic epilepsy.MethodsThis observation study evaluated the effect of 4 mg oral melatonin in ameliorating sleep–wake cycle, seizure frequency, and EEG features in children with focal idiopathic epilepsy of infancy. Twenty children were enrolled from September 2020 to August 2021. The study consisted of serial controls at enrollment (t0), at 3 months (t1), and at 6 months (t2) including neurological examination, questionnaire about sleep disturbances (CSHQ), and EEG.ResultsA significant improvement in sleep quality and daytime sleepiness was observed after melatonin supplementation. Furthermore, we observed a noteworthy improvement in EEG tracing at t2 that exhibited a significant correlation with improvements in CSHQ scores.ConclusionThe studies conducted so far to evaluate the effect of melatonin in persons with epilepsy do not lead to definitive conclusions. Despite the small population sample and the study design, we report sleep and EEG improvement after melatonin administration in our cohort. Larger studies are needed to further study the neuroprotective and anticonvulsant properties of melatonin.

Abstract Objective This study delineates the clinical and molecular spectrum of ANKLE2‐related microcephaly (MIC), as well as highlights shared pathological mechanisms between ANKLE2 and the Zika virus. Methods We identified 12 individuals with MIC and variants in ANKLE2 with a broad range of features. Probands underwent thorough phenotypic evaluations, developmental assessments, and anthropometric measurements. Brain imaging studies were systematically reviewed for developmental abnormalities. We functionally interrogated a subset of identified ANKLE2 variants in Drosophila melanogaster. Results All individuals had MIC (z‐score ≤ −3), including nine with congenital MIC. We identified a broad range of brain abnormalities including simplified cortical gyral pattern, full or partial callosal agenesis, increased extra‐axial spaces, hypomyelination, cerebellar vermis hypoplasia, and enlarged cisterna magna. All probands had developmental delays in at least one domain, with speech and language delays being the most common. Six probands had skin findings characteristic of ANKLE2 including hyper‐ and hypopigmented macules. Only one individual had scalp rugae. Functional characterization in Drosophila recapitulated the human MIC phenotype. Of the four variants tested, p.Val229Gly, p.Arg236*, and p.Arg536Cys acted as partial‐loss‐of‐function variants, whereas the c.1421‐1G>C splicing variant demonstrated a strong loss‐of‐function effect. Interpretation Deleterious variants in the ANKLE2 gene cause a unique MIC syndrome characterized by congenital or postnatal MIC, a broad range of structural brain abnormalities, and skin pigmentary changes. Thorough functional characterization has identified shared pathogenic mechanisms between ANKLE2‐related MIC and congenital Zika virus infection. This study further highlights the importance of a thorough diagnostic evaluation including molecular diagnostic testing in individuals with MIC.

IntroductionThe aim of our single-center case–control study is to evaluate whether minipuberty occurs in patients with hypoxic ischemic encephalopathy (HIE) who underwent therapeutic hypothermia (TH). We intend to conduct this evaluation by confronting the values of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) and the values of testosterone in males and estradiol in females between newborns with HIE and in subsequent TH and healthy controls.MethodsWe enrolled 40 patients (age: 56–179 days; 23 males), of whom 20 met the inclusion criteria for the case group and who underwent TH. A blood sample was taken from each patient at approximately 10 weeks of age to evaluate FSH and LH from the serum samples of all patients and to evaluate 17-beta estradiol (E2) and testosterone levels, respectively, from the serum samples of female and male patients.ResultsIt was found that minipuberty occurred in the case group patients, with no significant differences reported from the control group and with hormonal serum levels comparable to healthy infants of the control group (FSH 4.14 mUI/ml ± 5.81 SD vs. 3.45 mUI/ml ± 3.48 SD; LH 1.41 mUI/ml ±1.29 SD vs. 2.04 mUI/ml ±1.76 SD; testosterone in males 0.79 ng/ml ± 0.43 SD vs. 0.56 ng/ml ± 0.43 SD; 17-beta estradiol in females 28.90 pg/ml ± 16.71 SD vs. 23.66 pg/ml ± 21.29 SD).DiscussionThe results of the present study may pave the way for further research and the evaluation of more possible advantages of TH.

Acute lymphoblastic leukemia is the most common childhood malignancy. Despite many advances in therapy, about 15%–20% of children with acute lymphoblastic leukemia experience a disease relapse. Isolated ocular relapse is relatively rare. A 14-year-old male with T-cell acute lymphoblastic leukemia in remission presented with sudden onset of right eye pain and visual acuity impairment. Fundoscopic examination of the eye and magnetic resonance imaging of the orbits were consistent with optic nerve infiltration. The patient was treated with salvage chemotherapy, orbital radiation and eventual bone marrow transplantation, with notable improvement in vision and regression of retinal and optic nerve findings. Optic nerve infiltration represents an ophthalmic emergency and requires urgent management. The use of radiation therapy is a helpful adjunct with systemic chemotherapy in obtaining disease remission.

Autism spectrum disorder (ASD) is characterised by difficulties with social communication, interaction, and repetitive and stereotypical patterns of behaviour. Recent studies suggest that abnormalities in the corpus callosum (CC) can produce autistic symptoms, so this cerebral structure is a target for autism research. It is the largest area of white matter fibre that connects the cerebral hemispheres and has been considered an index of interhemispheric connectivity. The poor connectivity that is a characteristic of autism could be due to CC abnormalities. In this review, we describe empirical studies that have used functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) to investigate the role of the CC in functional and structural brain connectivity in individuals with ASD. Establishing the anatomical correlates of abnormal connectivity in ASD is a major objective of structural and functional connectivity studies. Reduced CC volume is one of the most consistent findings in studies of autistic brains. Structural connectivity studies have shown that the CC is generally altered in ASD. In addition, functional connectivity studies show atypical activity in individuals with ASD during social cognition tasks, working memory tasks, and tests of executive function. Research on functional and structural connectivity has contributed to understanding the role of the CC in the clinical symptoms and social and cognitive deficits associated with ASD.

Myelin oligodendrocyte glycoprotein antibody disease (MOGAD) is characterized by multiple phenotypic conditions such as acute disseminated encephalomyelitis, optic neuritis, and myelitis. MOGAD's spectrum is expanding, with potential symptoms of increased intracranial pressure that are similar to idiopathic intracranial hypertension (IIH). We report a boy with new-onset continuous headache and a brain MRI at onset suggesting idiopathic intracranial hypertension (IIH). The patient showed resistance to treatment with acetazolamide and, after one month, developed optic neuritis in the left eye. Laboratory tests documented positive MOG antibodies (anti-MOG) in the serum. The final diagnosis was MOGAD, with the initial symptoms resembling IIH. [ABSTRACT FROM AUTHOR]
