The Role of Supplements and Over-the-Counter Products to Improve Sleep in Children: A Systematic Review.

The sleep-wake cycle is a complex multifactorial process involving several neurotransmitters, including acetylcholine, norepinephrine, serotonin, histamine, dopamine, orexin and GABA, that can be, in turn, regulated by different nutrients involved in their metabolic pathways. Although good sleep quality in children has been proven to be a key factor for optimal cognitive, physical and psychological development, a significant and ever-increasing percentage of the pediatric population suffers from sleep disorders. In children, behavioral interventions along with supplements are recommended as the first line treatment. This systematic review was conducted, according to the PRISMA guidelines, with the purpose of assessing the principal nutrients involved in the pathways of sleep-regulating neurotransmitters in children and adolescents. Our focus was the utilization of over the counter (OTC) products, specifically iron, hydroxytryptophan, theanine and antihistamines in the management of different pediatric sleep disorders with the intention of providing a practical guide for the clinician.

Non-Pharmacological Treatments in Paediatric Migraine.

Psychological, social, and biological aspects contribute synergistically to the maintenance and chronicity of pain in primary headaches. An integrated intervention seems to be the most appropriate in the management of these conditions, taking advantage not only of pharmacological strategies, but also of different approaches according to the global assessment and patient necessities. In this perspective, non-pharmacological treatments are becoming increasingly used to overcome these issues also in paediatric migraine treatment. Particularly, nutraceuticals, non-invasive neuromodulation, and behavioural approaches are well tolerated and of potential interest. This paper aims to present the main approaches reported in the literature in the management of migraine in children and adolescents presenting an up-to-date review of the current literature. We therefore performed a narrative presentation for each of these three categories: nutraceuticals (riboflavin; magnesium; melatonin; vitamin D; coenzyme Q10; and polyunsaturated fatty acid); non-invasive neuromodulation (trigeminal nerve stimulator; non-invasive vagal nerve stimulation; transcranial magnetic stimulation; and remote electrical neuromodulation), and behavioural therapies (biofeedback; cognitive behavioural therapy; and mindfulness-based therapy). These approaches are increasingly seen as a valid treatment option in primary headache management also in paediatrics, avoiding medication overuse and drug treatment contraindications.

Psychiatric Manifestations in Children and Adolescents with Inherited Metabolic Diseases.

Background: Inherited metabolic disorders (IEMs) can be represented in children and adolescents by psychiatric disorders. The early diagnosis of IEMs is crucial for clinical outcome and treatment. The aim of this review is to analyze the most recurrent and specific psychiatric features related to IEMs in pediatrics, based on the onset type and psychiatric phenotypes. Methods: Following the PRISMA Statement, a systematic literature review was performed using a predefined algorithm to find suitable publications in scientific databases of interest. After removing duplicates and screening titles and abstracts, suitable papers were analyzed and screened for inclusion and exclusion criteria. Finally, the data of interest were retrieved from the remaining articles. Results: The results of this study are reported by type of symptoms onset (acute and chronic) and by possible psychiatric features related to IEMs. Psychiatric phenomenology has been grouped into five main clinical manifestations: mood and anxiety disorders; schizophrenia-spectrum disorders; catatonia; eating disorders; and self-injurious behaviors. Conclusions: The inclusion of a variety of psychiatric manifestations in children and adolescents with different IEMs is a key strength of this study, which allowed us to explore the facets of seemingly different disorders in depth, avoiding possible misdiagnoses, with the related delay of early and appropriate treatments.

Functional Tricuspid Regurgitation Model in a Beating Heart Platform.

Currently, clinicians are seeking new, minimally invasive treatment options for functional tricuspid regurgitation (FTR). Challenging tricuspid complexity requires the evaluation of the treatment techniques in adequate and realistic preclinical scenario. The purpose of this article is to describe the design and functional assessment of a novel passive beating heart model of the pulmonary circulation with the possibility to tightly control FTR. The model housed porcine hearts actuated by a volumetric pump that cyclically pressurized the right ventricle. The in-vitro FTR model exploited the tendency of the ventricle to dilate under pressure. The dilation entailed papillary muscles displacement and valve annulus enlargement, thus inducing tricuspid valve insufficiency. Employment of constraint bands allowed to restore valve competency. The system provided consistent replication of the main determinants of the pulmonary hemodynamics in a wide range of working conditions. The experimental model of FTR was reliable, easily controllable, and showed good stability-over-time. Echocardiography and fiberscope imaging provided a unique opportunity to investigate valve dynamics. These features make the platform suitable for realistic training purposes and testing of the upcoming FTR therapies.
