The development of diaphragmatic hernias, their associated physical and diagnostic signs and symptoms, and the potential complications with nitrous oxide use are presented with a case report. Depending upon the location and extent of the diaphragmatic defect, portions of the stomach, omentum, liver and/or intestine can occupy a portion of the thoracic cavity. Nitrous oxide's solubility properties allow for rapid expansion of the herniated bowel, resulting in compression of the thoracic organs or strangulation of the herniated abdominal viscera. The presence of a diaphragmatic hernia may necessitate a change in sedation or anesthesia plans to eliminate the use of nitrous oxide during prolonged procedures.

Epithelioma cuniculatum plantare is a tumor of epithelial origin occurring on the plantar aspect of the foot. It is an uncommon, locally aggressive neoplasm, not limited to this area, and in other body sites is referred to as verrucous carcinoma. The history and treatment of a patient with plantar verrucous carcinoma is presented; a survey of the literature reflects difficulty in establishing an early diagnosis. This, however, can be facilitated when the gross appearance and a history of prior surgical attempts to excise the lesion are known to the surgeon and the pathologist, and the surgical specimen ideally encompasses the deeper portions of the lesion.

This report describes identification of Factor VIII inhibitor in a patient who then received immune tolerance therapy. The precipitating event was a traumatic orofacial injury that was nonresponsive to traditional factor-replacement therapies. An inhibitor complicates medical and dental management of the hemophiliac patient because it counteracts usual techniques of hemorrhage control using coagulation agents derived from Factor VIII (Monoclate--Armour, Blue Bell, PA). Successful identification and management of the inhibitor patient require communication and consultation between the physician and dentist, up-to-date knowledge regarding the hemophiliac patient's bleeding and infusion history and aggressive application of local adjunctive hemostatic therapies.
