Angiotensin-Converting Enzyme Inhibitor-Induced Angioedema Following Posterior Reversible Encephalopathy Syndrome in a Child: A Case Report.

Angioedema is a rare but potentially lethal side effect of angiotensin-converting enzyme inhibitors (ACEIs). Most ACEI-induced angioedema (ACEI-AE) cases have been reported in adults, with few reports of cases in children. Posterior reversible encephalopathy syndrome (PRES) is a neurological disorder that presents with acute onset of symptoms, including headache, vomiting, visual disturbances, and seizures.

Hypercalcemic crisis caused by primary hyperparathyroidism in a 11-year-old boy: a rare case report and review of the literature.

Background: Hypercalcemic crisis caused by primary hyperparathyroidism (PHPT) in pediatric patients is very rare, and appropriate treatment approach for this condition has not been well demonstrated. Here, we report a case of PHPT-induced hypercalcemic crisis in a boy.

Case Description: An 11-year-old boy visited the clinic with abdominal pain and nausea that lasted for 3 months, but the cause of his symptoms could not be identified.
