[Postoperative pain after interventions in the area of the mouth-jaw-face].
In order to establish effective postoperative analgesia we studied the incidence and significance of pain following maxillofacial surgery. The trial included 102 patients undergoing one of six different surgical procedures. ⋯ Postoperative pain intensity was significantly correlated to operating time, the frequency of analgesic demand and the type of surgery (orthognathic surgery > TMJ surgery > osteosynthetic surgery > osteotomy of impacted third molars > tumor resection > removal of osteosynthetic materials). Patient's age, sex and ethnic origin did not significantly affect the severity of postoperative pain.

[Acoustic reflection position monitoring of tracheal cannulae. A contribution to quality assurance?].
Non-invasive acoustic airway monitoring was evaluated in an experimental study. Recording amplitude and travel time of acoustic pulse response, an area-distance function of the cross sectional dimensions of the endotracheal tube and the adjacent airway was calculated to obtain an acoustic pattern of the airway. Measurements on models and excised human cadaver lungs were performed to discover whether displacement or obstruction of the artificial airway can be detected in the acoustic equivalent. ⋯ Location and amount of obstruction could likewise be identified. Thus acoustic mapping provides an adequate approximation of the true geometry of tracheostomy and endotracheal tubes. We conclude that acoustic monitoring may provide a powerful tool to achieve primary prevention of airway disturbances in intubated and mechanically ventilated patients, as geometrical changes of airway configuration can be detected even before they cause substantial effects on respiratory metabolism.

Giant cell arteritis is a systemic disease of unknown origin characterized by vasculitis of medium-sized and larger vessels, found mainly in elderly women. It presents with a variety of symptoms, including temporal pain and tenderness, headache, and neuroophthalmic features. This report describes a case of giant cell arteritis in a 78-year-old woman with a large ulceration on the right side of the tongue, painful lesion in the right temporal area, and recent visus loss of the right eye.
