Umbilical wind

Also pursed mouth. Lockjaw in neonates. Umbilical wind is characterized by clenched jaws, arched-back rigidity, and a peculiar grimace. In severe cases, the facial complexion is green-blue, and there is hasty breathing. Attributable to unhygienic treatment or premature shedding of the umbilical cord. This disease has been almost largely eliminated by modern delivery methods.
