Differential diagnosis of hypocalcemia

2020-02-24 19:51 Summary. Hypocalcemia varies from a mild asymptomatic biochemical abnormality to a lifethreatening disorder. Acute hypocalcemia can lead to paresthesia, tetany, and seizures (characteristic physical signs may be observed, including Chvostek sign, which is poorly sensitive and specific of hypocalcemia, and Trousseau sign).

Brief H& P: 34M with a history of HTN, polysubstance abuse, presenting with muscle cramps. He reported onset of diffuse muscle cramping 1hour prior to presentation while showering. Symptoms involved bilateral upper and lower extremities and resolved spontaneously. On initial evaluation, the patient was tachycardic and hypertensive. differential diagnosis of hypocalcemia The diagnostic approach to hypocalcemia involves confirming, by repeat measurement, the presence of hypocalcemia and distinguishing among the potential etiologies. The diagnosis may be obvious from the patient's history; examples include chronic kidney disease and postsurgical hypoparathyroidism.

Hypocalcemia associated with low phosphate and low 25vitamin D usually indicates an absorptive problem. Differential diagnoses that should be considered include malabsorption states (sprue, short bowel, regional enteritis), hepatobiliary disease, anticonvulsant therapy, and vitamin D deficiency or resistance states.

Laboratory hypocalcemia is often asymptomatic, and its treatment in neonates is controversial. Hypocalcemia. Differential diagnosis and mechanisms. Signs and symptoms of hypocalcemia consisted of tetany (Chvostek's and Trousseau's signs), seizures, diminshed to absent deep tendon reflexes, papilledema, mental changes (weakness, fatigue, irritability, memory loss, confusion, delusion, hallucination), and skin changes.
