Arterial Gas Embolism in Breath-Hold Diver.

An arterial gas embolism (AGE) is a potentially fatal complication of scuba diving that is related to insufficient exhalation during ascent. During breath-hold diving, an arterial gas embolism is unlikely because the volume of gas in the lungs generally cannot exceed the volume at the beginning of the dive. However, if a diver breathes from a gas source at any time during the dive, they are at risk for an AGE or other pulmonary overinflation syndromes (POIS).

Skin cancer in the US Military.

There is an increased risk for melanomas and keratinocyte cancers in those who have served on active duty in the US Military. We believe that an increased exposure to UV radiation, minimal sun-protective strategies, and a paucity of education regarding the risks of UV exposure are primarily responsible for the increased prevalence of skin cancer in this population. Although mitigating these risks is important, it cannot come at the expense of combat effectiveness and military mission readiness.

Postoperative Nasal Septal Abscess Following Use of 2-Octylcyanoacrylate and Polydioxanone Plate in Open Septorhinoplasty: A Case Series.

Background: The employment of 2-octylcyanoacrylate adhesive (Dermabond) to assist graft placement in open septorhinoplasty has been increasingly used to stabilize cartilage grafts. Literature regarding this application has been mixed, with some showing the possibility of increased rates of inflammation, if not infection. We present an original comparative case series involving postoperative septal abscess formation adjacent to caudal strut grafting where both Dermabond and an absorbable polydioxanone (PDS) plate were used.
