Benign Acute Childhood Myositis: Our Experience on Clinical Evaluation.

BACKGROUND: Benign acute childhood myositis (BACM) is a transient condition mainly affecting children of school age characterized by muscle pain, typically localized to the calf muscle with symmetrical lower extremity pain and difficulty in walking. Usually, the symptomatology is preceded by a viral infection including influenza, parainfluenza, rotavirus, and mycoplasma. METHODS: The case series was conducted in four pediatric hospitals in Catania, Italy, over a 12-year observational period. Clinical examination, laboratory data, course, treatment, and complications of the affected children were extracted from electronic medical records of each hospital. RESULTS: For the case series, 50 children diagnosed with BACM were enrolled: the mean age of affected children was 5.35 years, 86% of were males, and in 56% the affections occurred during the winter. In the affected children, the clinical picture was characterized by previous fever and/or symptoms of inflammation of the upper airways, and followed by pain in the lower extremities up to uncoordinated gait. In 17 cases the etiological agent was isolated, including the influenza virus type B as the most frequent and influenza virus type A, Mycoplasma pneumoniae, beta-hemolytic streptococcus, and herpes simplex virus. Children were treated with supportive therapy. In all the children the muscular symptomatology had a good evolution with progressive marked reduction of pain and of the high level of CKemia. Neither clinical recurrences nor sequelae were reported. CONCLUSION: BACM shows to have in most of the cases a favorable evolution, a spontaneous remission of symptoms, and a good prognosis. However, the disorder generates parental distress for the acute presentation and the striking muscle dysfunction. It is worthy a rapid and early diagnosis to avoid unnecessary diagnostic investigations and a careful follow-up necessary to exclude persistence of symptoms or creatine kinase elevation.

Autoimmune encephalitis and CSF anti-AMPA GluR3 antibodies in childhood: a case report and literature review.

Acute autoimmune encephalitis is a severe neurological disorder presenting with altered level of consciousness, confusion, irritability, headache, vomiting, and in some cases seizures. An infective event precedes by 1-2 weeks the onset of the symptoms. Cognitive impairment is considered the cardinal symptom. The autoimmune encephalitis comprises an increasingly group of inflammatory brain disorder caused by an underlying abnormal immune response to the CNS to the infective agent. In children, several antibodies have been recorded as causative agent. Among these, GAD65, MOG, and NMDAR antibodies are more commonly reported and with less frequency, the Dopamine-2 receptor, GABA A receptor, GABA B receptor, and Glycinereceptorandm-GluR5. We report here a 10-year-old male with acute autoimmune encephalitis with altered status of consciousness and severe cerebral involvement at the brain-MRI. Serum and cerebrospinal fluid disclosed the presence of anti-AMPA-GluR3 antibodies suggesting a possible pathogenetic correlation with the disorder presented by the proband. Precocious treatment with intravenous methylprednisolone and immunoglobulin resulted in progressive but constant improvement. At 3-month follow-up, the clinical condition of the child and the neuro-radiological brain anomalies returned to the normal. At the 2-year follow-up, no recurrence or other disturbances were reported.

Point-of-care ultrasound (POCUS) pediatric resident training course: a cross-sectional survey.

BACKGROUND: Point-of-care ultrasound (POCUS) is becoming increasingly crucial in the Pediatric Emergency Department for objective patient examination. However, despite its growing interest and wide-ranging applications, POCUS remains relatively unexplored in general pediatric training and education. Many physicians still find it challenging to comprehend and implement. METHODS: A theoretical-practical POCUS course for pediatric residents was conducted at the University of Catania, Italy. The course's effectiveness and practical impact on residents was assessed through a pre-post training survey. The first part of the questionnaire focused on the self-perceived time needed to learn how to recognize the following conditions using POCUS: (i) Pleural effusion (ii) Lung consolidation (iii) Pneumothorax (PNX) (iv) Cardiac contractility (v) Pericardial effusion (vi) Perisplenic effusion (vii) Morison's pouch effusion (viii) Douglas' pouch effusion (ix) Filling and collapsibility of the inferior vena cava. In the second part, we compared the potential role of POCUS in (i) Reducing the use of ionizing radiation in children (ii) Increasing the sense of security in diagnosis and treatment decisions making and (iii) Increasing the residents' confidence level with POCUS after the course on a 1-to-10 rating scale. RESULTS: Seventy-two residents participated in the study. The statistical analysis showed significant pre-post differences in almost all the items considered, except for "cardiac contractility" and "PNX". Furthermore, the perceived potential role of POCUS in reducing ionizing radiation usage and the sense of security in diagnosis and treatment decisions showed statistically significant differences (p < 0.05) before and after the course. Data analysis also revealed a consistently high confidence level with POCUS after the course. CONCLUSIONS: The results highlight the importance of including a POCUS track course in pediatric post-graduate programs due to its simplicity, rapid learning time, and clinical usefulness. Based on these findings, it would be recommended to increase the teaching hours dedicated to the recognition of pneumothorax and cardiology POCUS examination. Emphasizing POCUS training in pediatric education can enhance patient care and diagnostic accuracy while minimizing radiation exposure.

Implementation of the WHO Standards to assess quality of paediatric care at the facility level using service users' perspective as source of data: a multicentre quality improvement study in Italy.

OBJECTIVES: There is little experience in the use of the WHO Standards for improving the quality of care (QOC) for children at the facility level. We describe the use of 75 WHO Standard based Quality Measures to assess paediatric QOC, using service users as a source of data, in Italy. STUDY DESIGN: In a cross-sectional study including 12 hospitals, parents/caregivers of admitted children completed a validated questionnaire including 75 Quality Measures: 40 pertinent to the domain of experience of care; 25 to physical/structural resources; 10 to COVID-19 reorganisational changes. Univariate and multivariate analyses were conducted. RESULTS: Answers from 1482 service users were analysed. Physical resources was the domain with the higher frequency of reported gaps in QOC, with key gaps (higher rates of responders reporting need for improvement and low variability across centres) being: (1) quality of meals (48.1%; range across facilities: 35.3%-61.7%); (2) presence of cooking areas (50.9%; range: 34.6%-70.0%); (3) spaces for family/friends (51.3%; range: 31.8%-77.4%). For experience of care, the most critical gap was the information on the rights of the child (76.6%; range: 59.9%-90.4%), with most other Quality Measures showing an overall frequency of reported need for improvement ranging between 5% and 35%. For reorganisational changes due to COVID-19 an improvement was felt necessary by <25% of responders in all Quality Measures, with low variability across centres. At the multivariate analyses, factors significantly associated with the QOC Index largely varied by QOC domain. CONCLUSIONS: The use of the 75 prioritised Quality Measures, specific to service users' perspective, enabled the identification of both general and facility-specific gaps in QOC. Based on these findings, quality improvement initiatives shall focus on a core list of selected Quality Measures common to all facilities, plus on an additional list of Quality Measures as more relevant in each facility.

Randomized Comparison of Helmet CPAP Versus High-Flow Nasal Cannula Oxygen in Pediatric Respiratory Distress.

BACKGROUND: The current study aimed to compare the efficacy and safety of 2 noninvasive respiratory support methods, which included helmet CPAP and high-flow nasal cannula (HFNC) in children with respiratory distress admitted to a pediatric intermediate care unit. METHODS: This study was a prospective observational study conducted on children with respiratory distress (age 1-24 months) who were admitted to our acute and emergency operative unit. All included subjects were randomly treated with helmet CPAP or HFNC in a 1:1 fashion until their clinical picture, oxygen saturation, and arterial blood gas (ABG) parameters resolved. The efficiencies of helmet CPAP and HFNC were evaluated by breathing frequency, SpO2 , ABG pH, ABG PaCO2 , ABG PaO2 , and PaO2 /FIO2 , recorded once at baseline and then after 1 and 6 h of treatment. Both noninvasive respiratory support modalities were compared with a control group of subjects with respiratory distress under standard therapeutic pharmaceutical protocols. RESULTS: We found that both helmet CPAP and HFNC were efficient in improving the clinical conditions of subjects with mild-to-moderate respiratory distress, although clinical response to helmet CPAP was more efficient and rapid compared with HFNC. Children who received respiratory support had a better clinical course in terms of hospitalization, days of intravenous rehydration therapy, and days of drug administration compared with the control group (P < .001). CONCLUSIONS: Based on our knowledge, the present study is the first research comparing the effects of CPAP and HFNC in respiratory distress resolution in a pediatric intermediate care setting. It aims to identify the most efficient treatment to avoid pediatric ICU admissions and endotracheal intubation and reduce the administration of drugs and days of hospitalization.
