Brachymetatarsia; How Important Can It Be in Adolescence?

Hypocalcaemia is a dangerous electrolyte imbalance with 18% prevalence in hospital admitted patients. 1 Regulation of calcium level is by 3 main calcium-regulating hormones. These hormones are parathyroid hormone (PTH), vitamin D, and calcitonin; and they act by effecting on the bowel, kidneys, and skeleton. Causes of hypocalcaemia includes vitamin D deficiency, hypoparathyroidism, renal diseases, hypomagnesaemia, hungry bone disease after parathyroidectomy, drugs like calcium chelators, massive blood transfusion, critical illness, parathyroid hormone resistance, vitamin D resistance. Pseudohypoparathyroidism (PHP) refers to a group of metabolic disorders in which resistance to parathyroid hormone leads to hypocalcaemia, hyperphosphatemia, and elevation of serum PTH level in the setting of normal renal function. Herein we report an interesting case of hypocalcaemia who came to the emergency department with suspicion to intracranial hemorrhage and lead to the diagnosis of pseudohypoparathyroidism.
