FERNANDEZ MARTINEZ, M.ª M. et al. Tetany secondary to deficiency rickets. []. , 27, 2, pp.656-658. ISSN 1699-5198.

Hypocalcemia is an uncommon illness in children. In developed countries the incidence of rickets has decreased significantly, although last years this patology is increasing at the expense of inmigration. Its etiology is due to different factors such as low sun exposure, inadequate clothing and bad feeding and excessive contributions in phytates, exclusive breastfeeding and genetic factors. We report a case of a teenager 13 year old from Pakistan, who consulted for myoclonus, paresthesias, hand midwife and asymmetry walking. The laboratory emphasizes hypocalcemia deficit of 25 (OH) D and increased parathyroid hormone. Administration of calcium and vitamin D along with changes in his diet normalized clinical and laboratory parameters. Due to increased migration, the lack of sun exposure and inadequate supply this disease which was almost forgotten will appear another time.
