Pericarditis as the Main Clinical Manifestation of COVID-19 in Adolescents.

Pediatr Infect Dis J 2021 05;40(5):e197-e199

From the Second Department of Paediatrics, National and Kapodistrian University of Athens, School of Medicine, P. and A. Kyriakou Children's Hospital, Athens, Greece.

Children and adolescents with severe acute respiratory syndrome coronavirus 2 infection usually have a milder illness, lower mortality rates and may manifest different clinical entities compared with adults. Acute effusive pericarditis is a rare clinical manifestation in patients with COVID-19, especially among those without concurrent pulmonary disease or myocardial injury. We present 2 cases of acute pericarditis, in the absence of initial respiratory or other symptoms, in adolescents with COVID-19. Read More

Androgenization in Klinefelter syndrome: Clinical spectrum from infancy through young adulthood.

J Pediatr Urol 2021 Feb 24. Epub 2021 Feb 24.

Department of Urology, University of Miami Miller School of Medicine, Miami, FL, USA.

Klinefelter syndrome (KS) is an uncommon chromosomal disorder in males that has a variable clinical appearance. Classic KS involves an extra X chromosome, (47, XXY), although other variations may exist, including a milder mosaic form as well as multiple extra sex chromosomes with more dramatic phenotypes. KS is underdiagnosed, especially pre-pubertally, owing to a paucity of concrete clinical signs; however, diagnostic rates increase during and after puberty, as the consequences of hypergonadotropic hypogonadism begin to manifest.

st Department of Neurology, Eginition Hospital, Medical School, National and Kapodistrian University of Athens, 157 80 Athens, Greece.

Congenital myopathies (CMs) constitute a group of heterogenous rare inherited muscle diseases with different incidences. They are traditionally grouped based on characteristic histopathological findings revealed on muscle biopsy. In recent decades, the ever-increasing application of modern genetic technologies has not just improved our understanding of their pathophysiology, but also expanded their phenotypic spectrum and contributed to a more genetically based approach for their classification.

Treatment of Obstructive Sleep Apnea in Children: Handling the Unknown with Precision.

J Clin Med 2020 Mar 24;9(3). Epub 2020 Mar 24.

Department of Child Health and the Child Health Research Institute, University of Missouri School of Medicine, Columbia, MO 65201, USA.

Treatment approaches to pediatric obstructive sleep apnea (OSA) have remarkably evolved over the last two decades. From an a priori assumption that surgical removal of enlarged upper airway lymphadenoid tissues (T&A) was curative in the vast majority of patients as the recommended first-line treatment for pediatric OSA, residual respiratory abnormalities are frequent. Children likely to manifest persistent OSA after T&A include those with severe OSA, obese or older children, those with concurrent asthma or allergic rhinitis, children with predisposing oropharyngeal or maxillomandibular factors, and patients with underlying medical conditions.

Respiratory Involvement in Patients with Neuromuscular Diseases: A Narrative Review.

Pulm Med 2019 26;2019:2734054. Epub 2019 Dec 26.

MSc Program in Sleep Medicine, Medical School, Democritus University of Thrace, Alexandroupolis, Greece.

Respiratory muscle weakness is a major cause of morbidity and mortality in patients with neuromuscular diseases (NMDs). Respiratory involvement in NMDs can manifest broadly, ranging from milder insufficiency that may affect only sleep initially to severe insufficiency that can be life threatening. Patients with neuromuscular diseases exhibit very often sleep-disordered breathing, which is frequently overlooked until symptoms become more severe leading to irreversible respiratory failure necessitating noninvasive ventilation (NIV) or even tracheostomy.

Fingolimod Improves the Outcome of Experimental Graves' Disease and Associated Orbitopathy by Modulating the Autoimmune Response to the Thyroid-Stimulating Hormone Receptor.

Thyroid 2019 09;29(9):1286-1301

Molecular Ophthalmology, Department of Ophthalmology, University Hospital Essen, University Duisburg-Essen, Essen, Germany.

Graves' disease (GD) and Graves' orbitopathy are associated with stimulating thyrotropin receptor (TSHR) autoantibodies and autoreactive T cells. Recent studies suggested that sphingosine-1-phosphate (S1P) signaling is involved in the pathogenesis of orbitopathy.

[Research progress on composite animal models of inflammatory bowel disease based on gene knockout].

Zhejiang Da Xue Xue Bao Yi Xue Ban 2018 Dec;47(6):665-670

Zhejiang University School of Medicine, Hangzhou 310058, China.

Establishing a suitable animal model is important for studying the mechanism of inflammatory bowel disease (IBD) and exploring new therapeutic approaches. Although a large number of IBD single gene knockout animal models have been established, single knockout of certain genes associated with human IBD susceptibility does not manifest symptoms of IBD or manifest extremely milder symptoms, while composite animal models based on other modeling factors can better simulate the clinical features of IBD. This article mainly introduces three novel composite animal models and elaborates the possible pathogenesis of each composite model:animal models established by gene double knockout have more obvious and earlier symptoms than single-knockout models; single gene knockout model with Helicobacter infection can help to study the role of microbial infections in the pathogenesis of IBD; on the basis of gene knockout, specific deletion of certain immune cells can be used to study the role of the immune cells in the development of IBD.

Computed Tomography Appearance of Uncorrected Congenital Heart Disease in Adults.

J Thorac Imaging 2019 May;34(3):W13-W22

Department of Radiology, University Hospital, Rutgers New Jersey Medical School, Newark, NJ.

The incidence of congenital heart disease (CHD) is about 4 to 10 per 1000 live births. While severe forms of CHD are usually diagnosed in infancy or childhood, milder and more survivable CHD may first manifest in the adult or may be discovered incidentally on imaging studies performed for other reasons. It is important to identify CHD in adults to implement appropriate treatment and prevent complications such as progression of pulmonary hypertension and development of heart failure. Read More
