Nonclassic congenital adrenal hyperplasia (NCCAH) is characterized by mild cortisol deficiency, excess androgens and adrenocorticotropin (ACTH) production, and often with various features of dysmetabolic syndrome. Elective bariatric surgery is one of the most effective long-term management strategies for severe obesity. Our case presents a 34-year-old woman with symptomatic NCCAH and class III obesity who status post Roux-en-Y gastric bypass (RYGB) had significant weight loss with metabolic resolution of NCCAH, and no longer required glucocorticoid (GC) therapy. At 11 months post operation and off GC therapy, she had a weight deficit of approximately 160 pounds (72.57 kg) with continued metabolic resolution of NCCAH markers including ACTH, 17-hydroxyprogesterone, and androstenedione. Presently, GC therapy remains one of the few available treatments for symptomatic NCCAH; however, long-term GC therapy has the potential for various complications and side effects. Our case presents elective bariatric surgery as a potential and unique treatment option for patients with NCCAH with associated class III obesity. The exact pathophysiologic basis for this effect and its potential role in long-term management of appropriate NCCAH patients requires further study. [ABSTRACT FROM AUTHOR]

Fahr syndrome is a rare neurologic disorder, usually affecting young and middle-aged adults, that can present with symptoms ranging from extrapyramidal to neuropsychiatric abnormalities. Pseudohypoparathyroidism (PHP), characterized by parathyroid hormone (PTH)-resistance or PTH-unresponsiveness at target organs, is associated with Fahr syndrome and typically presents with hypocalcemia. The following case presents a 39-year-old-woman with PHP complicated by symptomatic hypocalcemia, hypokalemia, and movement disturbances, who had computed tomography imaging showing basal ganglia calcifications consistent with Fahr syndrome. She initially presented with headache and was hospitalized for hypertensive emergency and severe hypocalcemia. Examination, including the neurologic examination, was unrevealing aside from hypertension and central adiposity. Laboratory tests were consistent with PHP, showing hypocalcemia with elevated PTH, and negative for hyperaldosteronism. Management of hypocalcemia consisted of intravenous calcium infusion, oral calcium carbonate, oral vitamin D3, and oral calcitriol. Patients with severe hypocalcemia and elevated PTH who present with new neurological symptoms despite normal general neurologic examination may warrant consideration for brain imaging to evaluate for Fahr syndrome. Further investigations are necessary to determine the prevalence of Fahr syndrome and hypokalemia in patients with PHP, explore if these findings are significantly associated with PHP-1b subtype, and ultimately inform potential new screening pathways for these patients.
