Unraveling Palisaded Encapsulated Neuroma: A Case Report and Diagnostic Challenges.

Palisaded encapsulated neuroma (PEN), also known as solitary circumscribed neuroma, is a rare, benign tumor of neuronal origin, often located on the head or neck. We present a case involving a 77-year-old Middle Eastern woman with a slowly enlarging, slightly symptomatic lesion on her upper lip. Histopathological analysis following a shave biopsy revealed the lesion to be a PEN.

Fabrication of Ag-doped BiOF-reduced graphene oxide composites for photocatalytic elimination of organic dyes.

Background: The Long-terM OUtcomes after the Multisystem Inflammatory Syndrome In Children (MUSIC) study aims to characterize the frequency and time course of acute and long-term cardiac and non-cardiac sequelae in multisystem inflammatory syndrome in children associated with COVID-19 (MIS-C), which are currently poorly understood.

Methods: This multicenter observational cohort study will enroll at least 600 patients <21 years old who meet the Centers for Disease Control and Prevention case definition of MIS-C across multiple North American centers over 2 years. The study will collect detailed hospital and follow-up data for up to 5 years, and optional genetic testing.

Assessing the utility of screening electrocardiograms in paediatric patients following COVID-19.

Objective: To determine the utility of screening electrocardiograms after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among children in detecting myocarditis related to coronavirus disease 2019 (COVID-19).

Study Design: A retrospective chart review was performed at a large paediatric academic institution to identify patients with prior SARS-CoV-2 infection who received a screening electrocardiogram by their primary care providers and were subsequently referred for outpatient cardiology consultation due to an abnormal electrocardiogram. The outcomes were the results from their cardiology evaluations, including testing and final diagnoses.

Kawasaki Disease Shock Syndrome vs Classical Kawasaki Disease: A Meta-analysis and Comparison With SARS-CoV-2 Multisystem Inflammatory Syndrome.

Background: The emergence of increasing reports worldwide of a severe inflammatory process and shock in pediatric patients resembling Kawasaki disease (KD)-and, more specifically, Kawasaki disease shock syndrome (KDSS)-prompted us to explore KDSS in a preamble of a systematic comparison between the 2 conditions.

Methods: We completed a systematic review of KDSS and performed a meta-analysis comparison between reported KDSS cases and KD controls.

Results: A total of 10 case-control series were included in the meta-analysis.

A Highly Efficient and Stable Photocatalyst; N-Doped ZnO/CNT Composite Thin Film Synthesized via Simple Sol-Gel Drop Coating Method.

The thin film of N-doped ZnO/CNT nanocomposite was successfully fabricated on soda lime glass substrate by a simple sol-gel drop-coating method. The structural, morphological, chemical, and optical properties of as prepared samples were characterized by a variety of tools such as X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM), Fourier Transform Infrared spectroscopy (FT-IR), and UV-visible spectroscopy. The hexagonal crystalline structure was confirmed from XRD measurement without any other impurity phase detection in samples.

Management of Multisystem Inflammatory Syndrome in Children Associated With COVID-19: A Survey From the International Kawasaki Disease Registry.

Background: Since April 2020, there have been numerous reports of children presenting with systemic inflammation, often in critical condition, and with evidence of recent infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This condition, since defined as the multisystem inflammatory syndrome in children (MIS-C), is assumed to be a delayed immune response to coronavirus disease 2019 (COVID-19), and there are frequently cardiac manifestations of ventricular dysfunction and/or coronary artery dilation.

Methods: We surveyed the inpatient MIS-C management approaches of the members of the International Kawasaki Disease Registry across 38 institutions and 11 countries.

Echocardiographic Assessment of Diastolic Function in Children with Incident Systemic Lupus Erythematosus.

The timing and etiology of diastolic impairment in pediatric-onset systemic lupus erythematosus (SLE) are poorly understood. We compared echocardiographic metrics of left ventricular diastolic function in children at SLE diagnosis to controls and identified factors associated with diastolic indices. Echocardiograms of children aged 5-18 years within 1 year of SLE diagnosis and age-/sex-matched controls were retrospectively read by blinded cardiologists.
