RESUMO
Hyperekplexia is a neurologic disorder characterized by an exaggerated startle reflex in response to different types of stimuli. Hyperekplexia is defined by the triad of neonatal hypertonia, excessive startle reflexes, and generalized stiffness following the startle. Although uncommon, hyperekplexia can lead to serious consequences such as falls, brain injury, or sudden infant death syndrome.Aim of this study was to identify cases of neonatal hyperekplexia with a confirmed genetic diagnosis and to establish the genotype-phenotype correlation at onset. Articles were selected from 1993 to 2024 and PRISMA Statement was applied including newborns within 28 days of life. So, we retrieved from literature 14 cases of genetically confirmed neonatal hyperekplexia. The onset of clinical manifestations occurred in the first day of life in 8 of 14 patients (57.14%). Clinical findings were muscle stiffness (100%), startle reflex (66.66%), apnea/cyanosis (41.66%), positive nose-tapping test (33.33%), jerks (33.33%), jitteriness (25%), and ictal blinking (25%). Genes involved were GLRA1 in 9 of 14 (64.28%), SLC6A5 in 2 of 14 (14.28%), GPHN in 1 of 14 (7.14%), and GLRB in 2 of 14 (14.28%). Patients showed heterozygous (66.66%) or homozygous (33.33%) status. In 7 of 14 cases (50%), the condition occurred in other family members. A genotype-phenotype correlation was not achievable.Timely diagnosis is crucial to improve the natural history of hyperekplexia avoiding/reducing possible major complications such as sudden infant death syndrome, brain injury, and serious falls. Early differentiation from epilepsy minimizes treatment cost and improves the quality of life of patients.
RESUMO
Klippel-Trenaunay syndrome is an uncommon, infrequent, congenital disorder characterized by a triad of capillary malformation, varicosities, and tissue and bone hypertrophy. The presence of two of these three signs is enough to obtain the diagnosis. Capillary malformations are usually present at birth, whereas venous varicosities and limb hypertrophy become more evident later. The syndrome has usually a benign course, but serious complications involving various organs, such as gastrointestinal and genitourinary organs, as well as the central nervous system, may be observed. Recently, Klippel-Trenaunay syndrome has been included in the group of PIK3CA-related overgrowth spectrum (PROS) disorders. In terms of this disorder, new results in etiopathogenesis and in modalities of treatment have been advanced. We report here a review of the recent genetic findings, the main clinical characteristics and related severe complications, differential diagnoses with a similar disorder, and the management of patients with this complex and uncommon syndrome.
RESUMO
Background: After its 2019 outbreak in Wuhan, scientists worldwide have been studying the epidemiology and clinical characteristics of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in children. Evidence indicates that children with SARS-CoV-2 infection are more likely to develop upper and lower respiratory tract infections in association with other infectious agents, such as Mycoplasma pneumoniae. Here, we conducted a systematic review of SARS-CoV-2 and Mycoplasma pneumoniae co-infection and their clinical course in children. Methods: We evaluated the published literature on SARS-CoV-2 by using the medical databases PubMed, Embase, Cochrane Library, Scopus, and Web of Science. In the searches, the Medical Subject Heading (MeSH) terms "SARS-CoV-2 and Mycoplasma pneumoniae" AND "co-infection SARS-CoV-2" were used. Studies describing co-infection with SARS-CoV-2 and Mycoplasma pneumoniae in children were included in the review. The study was conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: According to the PRISMA guidelines, of the 38 identified studies, 14 were conducted in children (children/adolescents 0-18 years), 6 of which were included in this review. In total, 5867 children under the age of 17 years were diagnosed with SARS-CoV-2 infection through real-time polymerase chain reaction analysis of nasopharyngeal swabs to detect viral RNA. Elevated serum IgM levels specific to Mycoplasma pneumoniae were observed in 534 children and were associated with a Kawasaki-like illness in one child. To date, all of the children are alive. Conclusion: This study underlines the importance of considering, depending on the clinical context, a possible co-infection between SARS-CoV-2 and atypical bacteria, such as Mycoplasma pneumoniae. Co-infections with other respiratory pathogens during the pandemic and hospital stay can cause mistakes in clinical diagnostic and drug treatment. Physicians should perform early differential diagnosis of SARS-CoV-2 in association with other infectious agents. Further studies are needed to have a real incidence of these co-infections and their impact on symptoms, course, and outcome of patients with SARS-CoV-2.
RESUMO
In the literature, deletions in the 2p16.3 region of the neurexin gene (NRXN1) are associated with cognitive impairment, and other neuropsychiatric disorders, such as schizophrenia, autism, and Pitt-Hopkins-like syndrome 2. In this paper, we present twins with deletion 2p16.3 of the NRXN1 gene using a comparative genomic hybridization array. The two children had a dual diagnosis consisting of mild cognitive impairment and neurodevelopmental delay. Furthermore, they showed a dysmorphic phenotype characterized by facio-cranial disproportion, turricephalus, macrocrania, macrosomia, strabismus, and abnormal conformation of both auricles with low implantation. The genetic analysis of the family members showed the presence, in the father's genetic test, of a microdeletion of the short arm of chromosome 2, in the 2p16.3 region. Our case report can expand the knowledge on the genotype-phenotype association in carriers of 2p16.3 deletion and for genetic counseling that could help in the prevention and eventual treatment of this genetic condition. Newborn carriers should undergo neurobehavioral follow-ups for timely detection of warning signs.
RESUMO
Craniosynostosis, the premature closure of cranial sutures, is one of the principal causes of pediatric skull deformities. It can cause aesthetic, neurological, acoustic, ophthalmological complications up to real emergencies. Craniosynostosis are primarily diagnosed with accurate physical examination, skull measurement and observation of the deformity, but the radiological support currently plays an increasingly important role in confirming a more precise diagnosis and better planning for therapeutic interventions. The clinician must know how to diagnose in the earliest and least invasive way for the child. In the past, technological limitations reduced the choices; today, however, there are plenty of choices and it is necessary to use the various types of available imaging correctly. In the future, imaging techniques will probably rewrite the common classifications we use today. We provide an updated review of the role of imaging in this condition, through the ages, to outline the correct choice for the clinician for an early and non-invasive diagnosis.
RESUMO
PURPOSE: Posterior plagiocephaly (PP) is a common clinical condition in pediatric age. There are two main causes of PP: postural plagiocephaly and craniosynostosis. Early diagnosis is important, as it prevents neurological complications and emergencies. Diagnosis in the past was often made late and with imaging tests that subjected the infant to a high radiation load. Suture ultrasound does not use ionizing radiation; it is easy to perform, allows an early diagnosis, and directs toward the execution of the cranial 3D-CT scan, neurosurgical consultation, and possible intervention. The aim of the study is to describe the high sensitivity and specificity of suture ultrasound for the differential diagnosis between plagiocephaly and craniosynostosis. METHODS: We reported our prospective experience and compared it with the data in the literature through a systematic review. The systematic review was conducted on electronic medical databases (PubMed, Embase, Cochrane Library, Scopus, and Web of Science) evaluating the published literature up to November 2020. According to Preferred Reporting Items for Systematic Reviews and Meta-ANALYSES (PRISMA statement), we identified 2 eligible studies. Additionally, according to AMSTAR 2, all included reviews have been critically rated as high quality. A total of 120 infants with abnormal skull shape were examined in NICU. All underwent clinical and ultrasound examination. RESULTS: Of the total, 105 (87.5%) had plagiocephaly and 15 dolichocephaly/scaphocephaly (12.5%). None of these had associated other types of malformations and/or neurological disorders. The synostotic suture was identified ultrasonographically in 1 infant and subsequently confirmed by 3D CT scan (100%). CONCLUSION: Cranial sutures ultrasonography can be considered in infants a selective, excellent screening method for the evaluation of skull shape deformities as first technique before the 3D CT scan exam and subsequent neurosurgical evaluation. Cranial suture ultrasonography should be considered part of clinical practice especially for pediatricians.

SARS-CoV-2 (Severe Acute Respiratory Syndrome, Coronavirus, type 2) is the virus responsible for the global pandemic of Coronavirus disease 2019 (COVID-19) that began in China in December 2019. The variability of nasal olfactory symptoms in pediatric patients is interlinked with possible warning signs, including respiratory, gastrointestinal, ocular, or dermatological symptoms. Skin findings in patients with COVID-19 can range from petechiae to papulovesicular rashes to diffuse urticaria and can be confused with rashes of non-COVID-19 conditions. These lesions typically appear early during COVID-19 and are thought to be secondary to viral replication or circulating cytokines. Herein, we discuss two pediatric cases, presenting with skin lesions, which tested positive for SARS-CoV-2, thus, briefly reviewing current literature for similar reports and related management. Although these lesions heal spontaneously in most cases, an adequate "targeted" therapeutic approach can shorten the time and the discomfort of the skin disease.

The 8p inverted duplication/deletion is a rare chromosomal rearrangement clinically featuring neurodevelopmental delay, mild to severe cognitive impairment, heart congenital defects and brain abnormalities. Patients affected also present typical facial dysmorphisms and skeletal malformations, and it is thought that the composite clinical picture may fall into the chromosomal rearrangement architecture. With the major aim of better framing its related clinical and diagnostic paths, we describe a patient carrying a de novo invdupde[8p] whose clinical features have not been described so far. Hence, through an extensive genotype-phenotype correlation analysis and by reviewing the dedicated scientific literature, we compared our patient's features with those reported in other patients, which allows us to place our proband's expressiveness in an intermediate area, widening the scope of the already known invdupde[8p] genotype-phenotype relationship.
RESUMO
Acute transverse myelitis (ATM) is a rare neurological condition that affects the spinal cord. Several events, including infections, autoimmune conditions, inflammatory, and drug-induced factors, may cause this disorder. Correct and rapid etiological diagnosis is necessary in order to start appropriate treatment that mainly consists of immunomodulating therapy, high dose intravenous corticosteroids, and in plasma exchange in noninfectious cases. The outcome is varied and depends on several factors. In children, the prognosis is usually good. We report a case of an 11-year-old boy who presented with interscapular pain, right leg steppage, homolateral hyposthenia of the upper limb, and signs of autonomic dysfunction. After performing specific and instrumental exams, a diagnosis of transverse myelitis was reached, and appropriate therapy was performed. A few days post-treatment, the child developed a secondary scoliosis, involving a thoracolumbar curve with loss of cervical and lumbar lordosis. After rehabilitative treatment was undertaken for 12 months, a complete recovery and normal restoration of spinal physiological curves was obtained. The pediatric cases of ATM have a good response to steroid therapy combined with physiotherapy. Collaboration among the various specialists is worthwhile, in order to lead to a correct and rapid diagnosis.
