Convulsions, laryngismus stridulus, tetany, or carpopedal spasm are all frequently met with.
Paroxysmal Laryngitis, or Laryngismus stridulus, is a nervous affection of the larynx that occurs in infants.
The symptom of laryngismus stridulus—the so-called breath-holding—alone need concern us, and that for a special reason.
Therefore the prognosis in every case of laryngismus and in every case of craniotabes has to be very guarded.
Nearly the same sort of hissing or whistling sound in breathing has been mentioned already as occurring in laryngismus stridulus.
