The Centers for Disease Control and Prevention mental health 2005 to 2011 report identifies that 13% to 20% of US children experience a mental disorder each year with significant individual and public health, social, and economic consequences. 1 While attention deficit hyperactive disorder is the most common childhood neurobehavioral disorder (estimated prevalence 8.6%), childhood anxiety panic attack disorder (estimated prevalence 4.7%) commonly occurs or is misdiagnosed in presence of other medical conditions that include hyperthyroidism, hyperparathyroidism or abnormal serum calcium levels, pheochromocytoma, vestibular dysfunctions, seizure disorders, and cardiopulmonary conditions. 2-4 Our teen female patient presented with panic attacks unresponsive to psychiatry consultation with short course of selective serotonin reuptake inhibitor therapy. Her family physician obtained basic metabolic blood tests and requested immediate attention of our medical center (University of Mississippi Medical Center [UMMC]) pediatric endocrine service to assess and correct her severe hypocalcemia. This brief report calls attention to symptoms and associated medical conditions to consider early in differential diagnosis and management of adolescent behavior disorders. Our patient's clinical course is unusual in its presentation of panic attack symptoms with hypocalcemia, its rapid 6-month progression of multiple endocrinopathies, and transient hypercalcemia with onset of adrenal insufficiency. We summarize medical literature pertinent to our patient's rare polyendocrinopathy. Methods Our patient received appropriate medical care for her presenting symptoms, diagnoses, and treatment. Her medical chart was reviewed, and all of her health information was de-identified by her attending physicians prior to submission for publication.
