Likewise, this group of experts urges health authorities to include people with intellectual disabilities and related conditions as a priority population (other chromosomal abnormalities other than Down syndrome, intellectual disability, congenital anomalies and conditions that cause disability with microcephaly), as well as the caregivers of people with this type of conditions. Vaccination in children with this type of disorders should be considered as part of the first priority group, once safe vaccines against SARS-CoV-2 are available for use in children and adolescents.Feeding problems during childhood have been described over time by various authors. In 2013, Avoi dant/Restrictive Food Intake Disorder (ARFID) was included in the Diagnostic and Statistical Ma nual of Mental Disorders, 5th Edition (DSM-5), as a new diagnosis within the Feeding and Eating di sorders, to describe a group of patients with avoidant or restrictive eating behaviors unrelated to body image disorder or weight loss desire. ARFID may appear as significant weight loss and/or nutritional deficiency and/or a marked interference in psychosocial functioning. There are three forms of pre sentation, which can co-occur or occur independently. The first one includes children with sensory aversions (selective), who reject certain foods due to their taste, texture, smell, or shape; the second one includes those children with poor appetite or limited intake (limited intake); and the third one includes those children who reject certain foods or stop eating as a result of a traumatic event (aversi- ve). Due to the recent incorporation of ARFID into the DSM-5, there is a lack of information regar ding its treatment. The purpose of this review is to clarify diagnostic criteria and to describe targeted management and treatment interventions with a multidisciplinary approach, without deepening on the treatment of organic medical causes. Medication errors (ME) are preventable incidents of inappropriate use of medications by health per sonnel or by the patient. These events can occur at any stage of drug use generating significant costs to the health system and, in some cases, these can even lead to death. The pediatric population is con sidered susceptible to ME with a prevalence 3 times higher than adult patients. To identify the prevalence of medication errors in hospitalized pediatric patients, as well as their classification according to the stage of use of the medication when they occurred. A literature review of ME in pediatrics was carried out through a Pubmed / Medline search using Mesh terms ("Medication Errors" and "Pediatrics") in the last 10 years. AZD1480 mouse Three investigators reviewed independently the identi fied articles considering the STROBE checklist for observational studies. 192 bibliographic references were identified, 22 of them were eligible for review and data collection. Studies reported an error rate between 1% and 58% of the evaluated medication indications, with errors reported in different processes of drug use. 9 articles (41%) described errors related only to prescription, mainly associated with incorrect dosage, 6 (27%) errors related to prescription, administration, and other processes, 3 (14%) related to prescription and administration, 2 (9%) related only to administra tion, 1 (4%) article reported errors related to conciliation, and 1 (4%) described errors related to preparation and administration. The studies reported different medication errors in the pediatric population. Most of them reported ME related to prescription followed by ME in the administration. Knowing the proportion of ME allows focusing interventions aimed at reducing their prevalence.The studies reported different medication errors in the pediatric population.

Several countries have declared health alerts for a new syndrome that occurs late in children exposed to COVID-19, called "multisystem inflammatory syndrome". These patients manifest symptoms si milar to Kawasaki disease, but at rare ages, and it is considered as the cytokine storm manifestation in children. The objective of this review is to present the available information on COVID-19 and its re lationship with Kawasaki's disease, as well as to explain the current hypothesis of this new syndrome, its physiopathology, clinical presentation, key differences with Kawasaki's disease, and its possible therapeutic interventions. Ductus arteriosus stenting is a palliative alternative for neonates with ductal-dependent pulmonary flow. To present an alternative of arterial access for percutaneous coronary intervention in neonates. A term neonate with low weight diagnosed with pulmonary atresia with intact ventricular septum and severe hypoplasia of the tricuspid valve with dependent coronary circu lation. Due to the surgical risk and femoral artery damage and the anatomy of the ductus arteriosus, a left axillary arterial puncture was decided where a 3.5-millimeter coronary stent was successfully placed. The patient developed an axillary spasm that resolved spontaneously. Alternati ve arterial access other than the femoral artery route is an option for neonates with high surgical risk and low birth weight.Alternati ve arterial access other than the femoral artery route is an option for neonates with high surgical risk and low birth weight. Hemophagocytic lymphohistiocytosis (HLH) is an exaggerated activation of the immune system which can be either primary (familial) or secondary. Familial hemophagocytic lymphohistiocytosis type 3 (FHL-3) is a severe immune disorder, caused by mutations in the UNC13D gene, which codes for a protein crucial to the cytotoxic function of lymphocytes. To describe the diagnostic relevance of next-generation sequencing in the approach of a patient with suspected FHL and to demonstrate the effectiveness of bone marrow transplantation as the only curative measure. 4-year-old preschool male, previously healthy, who presented with mononucleosis syndrome and positive IgM for Epstein Barr virus, developing hepatosplenomegaly and progressive clinical de terioration. A lymphoproliferative syndrome was suspected, which was ruled out by bone marrow aspiration, finding evidence of active hemophagocytosis. The patient met the criteria for hemophago cytic syndrome (bone marrow aspiration, pancytopenia, elevated ferritin, and hypertriglyceridemia) and, given the lack of response to first-line management, including antiviral treatment, a possible primary etiology was considered.
