[1] The pathognomonic feature of acute hypocalcaemia is tetany (typified by a Trousseau's sign) and is usually preceded by paraesthesia (peri-oral and acral), increased neuromuscular irritability (Chvostek's sign) and muscle cramps.
Chvostek's sign is prompted by tapping the facial nerve below the zygoma (about 1-2 inches anterior to the ear).
Positive Chvostek sign was observed but not Trousseau sign.
On examination, both Chvostek's and Trousseau's signs were present.

(i) Clinical signs are usually totally absent (chronic latent intracellular deficit) (ii) Neuromuscular: weakness; tremor; muscle fasciculation; dysphagia; positive Chvostek's sign (facial twitching as a reaction to facial nerve tapping); positive Trousseau's sign (application of a pressure cuff to transiently occlude the brachial artery resulting in spasm of muscles of the hand and forearm) (iii) Cardiac: arrhythmias and ECG changes (iv) Central nervous system: depression, agitation, psychosis, nystagmus, and seizures Table 5: Etiology of magnesium deficiency [6].
