Purpose: The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected over 43 million people resulting in over 1 million deaths. Approximately 2% of cases in the United States are children, and in most cases the child is either asymptomatic or has mild symptoms. However, some pediatric cases can present with Multisystem Inflammatory Syndrome (MIS-C). Understanding the epidemiology, clinical presentation, and management of MIS-C related to SARS-CoV-2 will help to streamline early diagnosis and treatment, particularly in pediatric patients with complex medical conditions.
Methods: This scoping review adopted methods from the Joanna Briggs Institute (JBI) manual for evidence synthesis and preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews (PRISMA-ScR) guidelines. Primary studies of patients meeting the Centers for Disease Control and Prevention (CDC) criteria for MIS-C from December 31st, 2019 to Oct 5th, 2020 were identified using PubMed and Scopus. Articles were screened for eligibility, and data collection was conducted on those fulfilling inclusion criteria.
Results: Of 417 studies identified, 57 met inclusion criteria, accounting for 875 patients from 15 countries. Globally, 57% of children affected with MIS-C were males. The median age was 9 years old, ranging from 6 months to 21 years. Forty-five percent of the patients had underlying comorbidities including obesity and lung disease. Fever, conjunctivitis and GI symptoms were common. Most MIS-C patients had high biomarkers including troponin I, N-terminal prohormone of B-type natriuretic peptide (NT-proBNP), D-dimer, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), white blood cells (WBCs), interleukin 6 (IL-6), procalcitonin, and ferritin. The treatment for most patients included IVIG and inotropic support.
Conclusion: MIS-C can be a unique and potentially life-threatening manifestation of SARS-CoV-2 in children and often requires medical intervention.

The prevalence of rheumatoid arthritis (RA) has sharply increased in recent years, posing a serious threat to human health. RA is characterized as a chronic, multisystem disease with morning stiffness and symmetric small joint pain. However, its fundamental processes are poorly understood.

Purposeof The Review: In this review article, we aim to provide an overview of the pathophysiology, the clinical features, the therapeutic management and prognosis of patients affected by Multisystemic inflammatory syndrome (MIS) with cardiac involvement, focusing on myocarditis and pericarditis.
Recent Findings: MIS is a multiorgan hyperinflammatory condition due to a cytokine storm following (within 4-12 weeks) SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) infection. First described in children, it also affects young adults without comorbidities, predominantly males with highly heterogeneous clinical manifestations, including cardiac involvement.

Sarcoidosis is an inflammatory multisystem disease characterised by non-necrotising granulomas that typically affect the lungs, lymph nodes, eyes, skin, liver, spleen, heart, bones and joints. Although rare, necrotising granulomas can also occur. In this report, we present a case of a healthy woman in her 60s who presented with a 1-year history of fatigue and generalised body aches.

Rett syndrome (RTT), which predominantly affects females, arises in most cases from mutations in the () gene. When MeCP2 is impaired, it disrupts the regulation of numerous genes, causing the production of dysfunctional proteins associated with various multi-systemic issues in RTT. In this review, we explore the current insights into molecular signaling related to monoamines, immune response, and mitochondrial function, and their implications for the pathophysiology of RTT.

Macrophage activation syndrome (MAS) can be regarded as a key factor determining the severity of multisystem inflammatory syndrome associated with COVID-19 in children (MIS-C), and often requires treatment in the intensive care unit (ICU) to avoid life-threatening complications. No reputable specific criteria for the diagnosis of MAS in MIS-C patients have yet been identified, and criteria currently used for the diagnosis of hemophagocytic syndromes, such as HLH-2004, MAS-2005, and MAS-2016, are not sufficient for MAS in MIS-C. Our goal in this study was to work out the criteria for the early diagnosis of MAS in MIS-C.
