Paradoxical Vocal Cord Motion in a Pair of Twin Preterm Infants

Background: Intractable obstructive apneas requiring multiple intubations are rare innewborns. Case characteristics: We report a pair of twins born at 29 weeks gestationwho had severe obstructive apneas due to Paradoxical Vocal Cord Motion (PVCM).Outcome: The symptoms resolved promptly with ipratropium nebulization. Follow-up at12 months of age revealed normal development. Message: PVCM should be consideredin the differential diagnosis of intractable obstructive apneas in very low birth weightpreterm infants

Periodontal regeneration--fantasizing the future.

Periodontal Regenerative Surgical Procedures are, by definition, supposed to restore all three tooth-supporting tissues i.e. periodontal ligament fibres, alveolar bone and the cementum. In humans, we can now regenerate considerable amounts of alveolar bone, and periodontal ligament with the use of bone graft material and barrier membranes. The purpose of this article is to acquaint the reader with the current trends as well as some new areas along which periodontal regenerative therapy might shape up in the future. Since, some fields are still in their infancy, it can be only envisioned as to how these new fields of science might constantly evolve to redefine periodontal therapy in due time.
