Insights

Multisystem inflammatory syndrome in children (MIS-C) is a serious condition associated with COVID-19. Early treatment with steroids and IVIG improved outcomes in critically ill children.

Area of Science:

  • Pediatric critical care
  • Infectious diseases
  • Pediatric rheumatology

Background:

  • Multisystem inflammatory syndrome in children (MIS-C) is an emerging condition linked to SARS-CoV-2.
  • Increasing global reports highlight the need to understand MIS-C's clinical spectrum and management.

Purpose of the Study:

  • To describe the clinical features and management of MIS-C patients requiring pediatric intensive care.
  • To evaluate the outcomes of MIS-C patients treated with immunomodulatory therapies.

Main Methods:

  • Retrospective study of 21 children meeting WHO criteria for MIS-C admitted to the pediatric intensive care unit.
  • Data collected on clinical presentation, laboratory markers, echocardiography, and treatments received.
  • Analysis of outcomes including mortality and discharge status.

Main Results:

  • The cohort comprised 21 children (median age 7 years), predominantly without comorbidities.
  • Common symptoms included fever (100%) and gastrointestinal issues (76%). Most presented with shock (95%) requiring significant cardiovascular support.
  • Elevated inflammatory markers (CRP, ferritin, IL-6) were observed. Cardiac involvement (left ventricular dysfunction, coronary dilatation) was noted. 86% were discharged, 14% died.

Conclusions:

  • MIS-C in this cohort primarily affected previously healthy children, presenting with fever, GI symptoms, and shock.
  • Aggressive management of shock combined with immune modulation (methylprednisolone, IVIG) was crucial.
  • This intensive care experience underscores the severity of MIS-C and the importance of prompt, multidisciplinary management.

Myocarditis IV: Nursing Management

Myocarditis is an inflammatory condition of the myocardium requiring meticulous nursing management for optimal patient outcomes. Effective management begins with a thorough assessment of the patient's medical history, paying close attention to past infections, autoimmune disorders, travel history, and exposure to toxins or drugs. Recent viral infections and systemic diseases are particularly relevant due to their potential role in triggering myocarditis.Physical Examination and MonitoringThe...

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Pleural Effusion Overview
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
