RESUMO
Failure to thrive in the setting of profound hypotonia and multiple electrolyte derangements is a challenging constellation of findings that offers a broad differential diagnosis for providers to consider. Initial management should focus on the stabilization of the patient and correction of potential life-threatening electrolyte derangements. Once completed, the diagnosis should be sought, and in this case, many were considered and ultimately ruled out with thorough history and physical examination. Laboratory abnormalities revealed the final diagnosis of pseudohypoaldosteronism and connected the case. With proper treatment, our patient had a resolution of laboratory anomalies along with improved growth and tone.
RESUMO
Macrophage activation syndrome (MAS) as the initial presentation of systemic juvenile idiopathic arthritis (sJIA) is an uncommon and difficult diagnosis to ascertain. However, it remains critical to establish the diagnosis since MAS is a potentially life-threatening systemic inflammatory condition. Prompt recognition can lead to early initiation of treatment with corticosteroids and overall improved outcomes. Here, we present a case of a 14-year-old female with MAS as the initial manifestation of sJIA.
RESUMO
Acute ischemic stroke (AIS) is a significant source of morbidity and mortality and is one of the top causes of death in the United States. Of these patients, most are elderly individuals, compared to a limited proportion of cases seen in pediatrics. AIS is classically associated with age-dependent atherosclerotic disease processes secondary to comorbidities such as diabetes and hypertension. When considering the pediatric population, stroke is far less common and often requires workup of other underlying etiologies that create a hypercoagulable state. Here we present a case of an eight-year-old male with a left middle cerebral artery (MCA) ischemic stroke in the setting of increased factor VIII activity and SARS-CoV-2 antibodies.
