Recent studies have demonstrated a role for calcium channel blocking agents in the treatment of persistent hyperinsulinemic hypoglycemia of infancy. We report a 30 day old infant with PHHI whom we successfully treated with oral nifedipine alone.
Background: Psychosis secondary to paediatric Cushing’s disease (CD) is extremely rare and presents a significant management challenge. Method: We report a 14.7-year-old CD patient with acute psychosis and self-inflicted injuries following failed transsphenoidal pituitary surgery. Her mental state rapidly deteriorated precluding medical therapy. Results: Emergency intravenous low-dose etomidate infusion (3–3.5 mg/h) with dose titration according to the serum cortisol combined with a hydrocortisone infusion, in an intensive care setting, was effective in controlling the hypercortisolaemia. Her mental state improved with normalisation of her cortisol levels enabling oral administration of ketoconazole and bilateral adrenalectomy to be performed. Conclusion: This case illustrates the safe and effective use of a low-dose etomidate infusion in an unusual case of paediatric CD.
The use of adenosine infusion in combination with inhaled nitric oxide may be a potentially valuable therapeutic option for the treatment of pulmonary hypertension of the newborn. Neonates with irreversible lung pathology may not respond to adenosine infusion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
