Pediatric Adrenal Insufficiency: Challenges and Solutions
Full text linkAdrenal insufficiency is an insidious diagnosis that can be initially misdiagnosed as other life-threatening endocrine conditions, as well as sepsis, metabolic disorders, or cardiovascular disease. In newborns, cortisol deficiency causes delayed bile acid synthesis and transport maturation, determining prolonged cholestatic jaundice. Subclinical adrenal insufficiency is a particular challenge for a pediatric endocrinologist, representing the preclinical stage of acute adrenal insufficiency. Although often included in the extensive workup of an unwell child, a single cortisol value is usually difficult to interpret; therefore, in most cases, a dynamic test is required for diagnosis to assess the hypothalamic-pituitary-adrenal axis. Stimulation tests using corticotropin analogs are recommended as first-line for diagnosis. All patients with adrenal insufficiency need long-term glucocorticoid replacement therapy, and oral hydrocortisone is the first-choice replacement treatment in pediatric. However, children that experience low cortisol concentrations and symptoms of cortisol insufficiency can take advantage using a modified release hydrocortisone formulation. The acute adrenal crisis is a life-threatening condition in all ages, treatment is effective if administered promptly, and it must not be delayed for any reason
Effects of Intraoperative Auditory Stimulation on Pain and Agitation on Awakening After Pediatric Adenotonsillectomy: A Randomized Clinical Trial
No full textIMPORTANCE: Severe pain on awakening (POA) and emergence delirium (ED) are common following pediatric adenotonsillectomy. Effective preventive interventions are lacking. OBJECTIVE: To determine the effects of intraoperative auditory stimulation on reduction of POA and ED after pediatric adenotonsillectomy. DESIGN, SETTING, AND PARTICIPANTS: Single-center, double-blinded, 4-armed, randomized clinical trial of children undergoing adenotonsillectomy from March 2018 to May 2019 at a tertiary care pediatric referral center. INTERVENTIONS: Children were randomized to 1 of the following groups: auditory stimulation with music, auditory stimulation with noise, ambient noise insulation with masking earplugs, and a control group receiving no intervention. Ear inserts were placed in the operating room once general anesthesia was administered. Stimulation parameters were based on the preoperative audiological evaluation and the appropriate fitting of the transduction system, including ambient noise level monitoring. MAIN OUTCOMES AND MEASURES: The primary outcome was POA levels measured on 10-point scales according to age-appropriate validated tools. The secondary outcome was ED levels assessed according to the Pediatric Anesthesia Emergence Delirium 20-point scale. RESULTS: A total of 104 consecutive healthy children (median [interquartile range] age at surgery, 5.0 [3.8-6.4] years) were included in the analysis. Music had a large effect size on POA (0.63; 98% CI, 0.43-0.84) and a medium effect size on ED (0.47; 98% CI, 0.21-0.75), while noise had a medium effect size on POA (0.47; 98% CI, 0.22-0.73) and a large effect size on ED (0.63; 98% CI, 0.44-0.85) compared with controls. The earplugs group showed a small effect size on POA and ED. Considering a clinically meaningful threshold of greater than 4 for POA and 10 or greater for ED at dichotomized analysis, a large effect size was achieved by music (1.39; odds ratio [OR], 0.08; 98% CI, 0.02-0.29; and 0.84; OR, 0.22; 98% CI, 0.06-0.75, respectively) and noise (0.97; OR, 0.17; 98% CI, 0.05-0.6; and 1.48; OR, 0.07; 98% CI, 0.02-0.26, respectively), while earplugs resulted in a small effect size. CONCLUSIONS AND RELEVANCE: In this randomized clinical trial, children undergoing adenotonsillectomy who received intraoperative auditory stimulation demonstrated a clinically meaningful decrease in POA and ED in the immediate postoperative period. Further research is needed to assess whether intraoperative auditory stimulation may decrease POA and ED in children undergoing other types of surgical procedures.

Use of ketamine by paediatricians in Italian paediatric emergency departments: a missed opportunity?
No full textProcedural sedation and analgesia with ketamine are part of daily practice for children undergoing painful procedures in the paediatric emergency department (ED) of North America. A massive number of studies demonstrate ketamine's safety and efficacy in the hands of trained ED paediatricians, with few severe adverse events (SAEs) recorded. Since there are no data on ketamine's usage in Italian paediatric EDs, we created a survey to examine procedural sedation with ketamine in the EDs of the Italian PIPER (Pain in Paediatric Emergency Room) group, which includes 36 paediatric EDs providing 1.4 million paediatric visits each year. Results were reviewed using frequencies to describe responses. Thirty-two out of 36 centres replied to the questionnaire. In 6 (19%) out of 32 centres, ketamine is not used at all in the paediatric ED. In 6 centres (23%) of 26 which use ketamine, this drug is autonomously administered by the emergency paediatrician, whereas in 20 (77%) of them it is exclusively managed by the anaesthesiologist on call.Conclusion: ketamine is autonomously administered only by a small percentage of Italian emergency paediatricians. There is an increasing need for implementation of procedural sedation training and use of ketamine in the everyday practice outside the operating room in paediatric EDs. What is Known: • Ketamine is safely and efficaciously administered for children's procedural sedation and analgesia by trained emergency paediatricians in the everyday practice outside the operating room in North America. • In the Italian setting, there are no data at all concerning ketamine's usage by the emergency paediatricians for procedural sedation and pain control. What is New: • In this study emerged that ketamine is poorly administered by Italian emergency paediatricians for procedural sedation and analgesia outside the operating room. • A great deal of educational effort should be made to widen ketamine based procedural sedation availability in Italian emergency departments by spreading specific training tracks and guidelines
Lipoblastoma as a cause of secondary omental torsion in children: report of the first case
Full text linkAcute abdominal pain remains a major diagnostic challenge to date. Omental torsion is an infrequent cause of abdominal pain in children, which usually presents with non-specific symptoms. Herein, we report a case of persistent abdominal pain after a minor abdominal trauma. A solid mass was found in the lower abdomen at ultrasound imaging evaluation. Surgical exploration demonstrated an omental torsion secondary to a rare neoplasm of childhood
Ipertiroidismo e tiroidite autoimmune in età evolutiva
No full textHyperthyroidism is a rare clinical entity in paediatric age. In most cases the etiology is autoimmune and goiter represents the typical presentation. Ophthalmopathy is rare and can precede the diagnosis of autoimmune hyperthyroidism. Thyrotoxicosis caused by the hyperthyroid phase of Hashimoto’s thyroiditis must be carefully distinguished from Graves’ disease (GD), since the first condition has a better prognosis for spontaneous remission. Three treatment options are currently available for the management of paediatric GD. First-line therapy is antithyroid drugs, while thyroidectomy and radioiodine are considered on relapse. A lower remission rate and a higher risk of adverse events are observed after the first course of methimazole in childhood with respect to adulthood. Children and adolescents may require a prolonged antithyroid treatment, but an overall consensus regarding the optimal regimen is lacking
Omalizumab effectiveness in patients with a previously failed oral immunotherapy for severe milk allergy
Full text linkBackground: Some studies addressed the issue of omalizumab (OML) effectiveness in children starting their first oral immunotherapy (OIT) attempt but no study investigated the possible role of OML in the setting of patients with persisting milk allergy after a failed OIT attempt.Methods: Single-center, prospective, observational study in a selected group of patients with a persisting and severe cow milk (CM) allergy associated with moderate allergic asthma, in which a previous OIT attempt had already failed. We performed an open oral food challenge (OFC) to identify patients who tolerated less than 173 mg of cow's milk protein. At the end of the recruitment, we have found four patients with a mean age of 16.25 years (8-24) who had suspended a previous OIT attempt and still reacted to an amount of CM equal or below 173 mg. Enrolled patients, after an 8-week course of OML along with a CM avoiding diet, underwent again an open OFC with CM to re-evaluate their threshold. Eventually, a new OIT course was started using the same OIT protocol of the previous attempt, maintaining cotreatment with OML for the first 12 months. For each patient, we documented: the threshold of CM at OFC, level of specific immunoglobulin E (IgE) and IgG4 for milk, and quality of life (QoL).Results: During OIT the four patients experienced no reactions or extremely mild ones (oral itching, transient mild abdominal pain). All increased their threshold of CM in OML if compared with the baseline and maintained it long after that biologic therapy had discontinued. Specific milk proteins IgG4 levels significantly increased in all.Conclusion: In this series, OML was effective in patients with severe CM allergy who had previously failed OIT, allowing milk intake without adverse reactions and improving the QoL
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
