Opisthotonos
From Ganfyd
Classically described with tetanus, and illustrated by Sir Charles Bell in a painting[1] of a wounded soldier dying of it, the spasm in the long muscles leaves the patient resting on his head and heels, arched backward.
Also seen, rarely in lithium toxicity and with strychnine poisoning.
Paediatrics
When associated with gastro-oesophageal reflux in infants, it constitutes the Sandifer syndrome.
