A case of phace syndrome and acquired hypopituitarism?

<p>Abstract</p> <p>Background</p> <p>PHACE is a neurocutaneous syndrome associated with: Posterior fossa brain malformations, large “segmental” facial hemangiomas, arterial cerebrovascular-, cardiovascular-, and eye anomalies.</p> <p>Case vignette</p> <p>We are reporting a girl with PHACE syndrome. The patient had a congenital right-sided facial hemangioma with plaque-morphology. At age 11 years and 2 months she presented with short stature, markedly decreased growth velocity and signs and symptoms suggestive of hypothyroidism. Magnetic Resonance Imaging (MRI) of the brain revealed complex structural and cerebrovascular arterial anomalies, including an empty sella. Testing of pituitary function revealed multiple pituitary dysfunctions, including absolute growth hormone deficiency, hypogonadotropic hypogonadism, central hypothyroidism, and secondary adrenal insufficiency.</p> <p>Conclusions</p> <p>This case suggests the necessity to screen all patients with PHACE syndrome and intracranial malformations for pituitary dysfunction at regular intervals.</p

Treatment of Hypothalamic Obesity with Dextroamphetamine: A Case Series.

BackgroundA limited number of published case reports suggest a positive effect of dextroamphetamine, an adrenergic agonist affecting both the central nervous system (CNS) and peripheral nervous system, on physical activity and weight in patients with hypothalamic obesity (intractable obesity following CNS insult). Here, we present our clinical experience with dextroamphetamine treatment for hypothalamic obesity.MethodsThe clinical course of all patients started on dextroamphetamine treatment for severe hypothalamic obesity at our institution between 2010 and 2013 is reported. Dextroamphetamine administration was initiated at a single dose of 5 mg per day and titrated to effect up to a dose of 20 mg/day. BMI z-score velocity was calculated as change in BMI z-score over standardized intervals of 12 months. Parameters of treatment success and adverse events were assessed in a standardized fashion.ResultsSeven patients (2 males; mean age 17.6 years [range 12.9-24.5]) underwent individual treatment attempts with dextroamphetamine between 2010 and 2013. The primary diagnoses were craniopharyngioma (n = 4), ganglioglioma WHO I (n = 1), astrocytoma (n = 1), and neonatal meningitis (n = 1). Time from initial CNS insult to initiation of dextroamphetamine treatment averaged 5.2 years (range 2.4 months to 16.5 years). All patients demonstrated a steady increase in BMI z-score from the time of initial diagnosis until initiation of dextroamphetamine treatment. Mean baseline BMI z-score was +3.17 ± 0.93 (+1.9 to +4.4). Mean BMI z-score velocity decelerated to -0.18 ± 0.12 per year during the first year of treatment and stabilized at +0.05 ± 0.32 per year during the second year of treatment. No significant adverse events were reported.ConclusionDextroamphetamine treatment led to stabilization or reduction of BMI z-score in a cohort of 7 patients with hypothalamic obesity, with no adverse effects. Considering the projected increase in BMI z-score according to the natural course of the disease, these findings are promising and warrant further study
