Severe Acute Respiratory Syndrome – Coronavirus – 2 (SARS-CoV-2) and its related Coronavirus Disease – 19 (COVID-19) has become a health emergency worldwide. The medical community has been concerned since the beginning of the outbreak about the potential impact of COVID-19 in children, especially in those with underlying chronic diseases. Fortunately, COVID-19 has been reported to be less severe in children than in adults. However, epidemiologic and clinical data are scarce.

The study aimed to investigate the correlations among immune, haematological, endocrinological markers and fitness parameters, and assess if the physiological parameters could be a predictor of fitness values. Anthropometric, physical evaluations (countermovement jump—CMJ, 10 m sprint, VO2max, repeated sprint ability—RSA total time and index) and determination of blood (IL-6, IL-10, IL-17A and tumour necrosis factor) and salivary (testosterone and cortisol) samples parameters in 28 young male soccer players (age: 13.0 ± 0.2 years, body mass index (BMI): 19.5 ± 2.2 kg/m2) were analysed.

OBJECTIVE: To examine whether sustained minimal manifestation status (MMS) with complete withdrawal of prednisone is better achieved in thymectomized patients with myasthenia gravis (MG). METHODS: This study is a post hoc analysis of data from a randomized trial of thymectomy in MG (Thymectomy Trial in Non-Thymomatous Myasthenia Gravis Patients Receiving Prednisone Therapy [MGTX]). MGTX was a multicenter, randomized, rater-blinded 3-year trial that was followed by a voluntary 2-year extension for patients with acetylcholine receptor (AChR) antibody-positive MG without thymoma.

Headache disorders are prevalent and disabling conditions impacting on people of all ages, including children and adolescents with substantial impact on their school activities and leisure time. Our study aims to report specific information on headaches in children and adolescents based on the Global Burden of Disease (GBD) study, that provides estimates for incidence, prevalence, fatal and non-fatal outcomes. We relied on 2007 and 2017 GBD estimates for prevalence and Years Lived with Disability (YLDs) at the global level and in WHO regions.

INTRODUCTION: Many studies on removable retainers have focused on retention efficacy and characteristics. However, studies on plaque accumulation, periodontal health, breakages, and patient compliance are still lacking. Thus, in this study, we aimed at evaluating these parameters in 2 groups of young patients wearing Essix or Hawley retainers for a 6-month period.

Human Dental Pulp Stem Cells (hDPSCs) represent a type of adult mesenchymal stem cells that have the ability to differentiate in vitro in several lineages such as odontoblasts, osteoblasts, chondrocytes, adipocytes and neurons. In the current work, we used hDPSCs as the experimental model to study the role of recombinant prion protein 23–231 (recPrP C ) in the neuronal differentiation process, and in the signal pathway activation of ERK 1/2 and Akt.

INTRODUCTION: Temporomandibular disorders (TMD) are an heterogeneous group of disorders affecting temporomandibular joints (TMJ), masticatory muscles, or both. The aim of this study is to evaluate the relationship between general health and psychological distress variables and the clinical diagnosis of TMD in children between 8 - 13 years old. Moreover, it will be underlined the different perception of psychological distress existing between patients and their parents.

ABSTRACT Objective: The aim of this research was to compare the prevalence of temporomandibular disorders (TMDs) among Venezuelan and Italian adolescents. Methods: One hundred-seventeen Venezuelan and 138 Italian adolescents aged 11–18 years were examined according to the Diagnostic Criteria for TMDs (DC/TMD). Signs and symptoms were registered. Results: TMD prevalence among Venezuelan adolescents (17.9%) was lower than that among Italian adolescents (29.7%) and was higher in females and in the 15–18 age group.

Maxillo-mandibular reconstruction in pediatric patients involves particular functional and cosmetic implications. Attention is required for the craniofacial growth over time, involvement of the permanent dentition, facial symmetry, and donor site morbidity. Our aim is to identify the best reconstructive options for maxilla-mandibular defects in children (<18 years) based on our experience with 25 pediatric patients. We believe that reconstruction has to be performed at the same time as resection in pediatric patients.
