Hypocalcemia is an uncommon illness in children. In developed countries the incidence of rickets has decreased significantly, although last years this pathology is increasing at the expense of immigration. 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.

Introduction: Uremic syndrome of chronic kidney disease (CKD) is a term used to describe clinical, metabolic, and hormonal abnormalities associated with progressive kidney failure. It is a rapidly growing public health problem worldwide. Nervous system complications occur in every patient with uremic syndrome of CKD. Areas covered: This review summarized central and peripheral nervous system complications of uremic syndrome of CKD and their pathogenic mechanisms. They include cognitive deterioration, encephalopathy, seizures, asterixis, myoclonus, restless leg syndrome, central pontine myelinolysis, stroke, extrapyramidal movement disorders, neuropathies, and myopathy. Their pathogenic mechanisms are complex and multiple. They include (1) accumulation of uremic toxins resulting in neurotoxicity, blood-brain barrier injury, neuroinflammation, oxidative stress, apoptosis, brain neurotransmitters imbalance, ischemic/microvascular changes, and brain metabolism dysfunction (e.g. dopamine deficiency), (2) metabolic derangement (as acidosis, hypocalcemia, hyperphosphatemia, hypomagnesemia, and hyperkalemia); (3) secondary hyperparathyroidism, (4) erythropoietin and iron deficiency anemia, (5) thiamin, vitamin D, and other nutritional deficiencies, (6) hyperhomocysteinemia, and (7) coagulation problems. Expert commentary: Nervous system complications of uremia contribute to the patients' morbidity and mortality. Optimizing renal replacement therapy, correction of associated metabolic and medical conditions, and improved understanding of possible pathogenic mechanisms of these complications is a major target for their prevention and treatment.
