Malignant Hyperthermia: A Case Report in a Trauma Patient.

Malignant hyperthermia is a rare condition that occurs in susceptible patients exposed to triggering anesthetic agents. It is associated with a high mortality rate if not recognized immediately and treated appropriately. A 52-year-old man presented to our clinic 2 days after an assault for management of jaw pain. A minimally displaced right parasymphyseal fracture and moderately displaced left body fracture of the mandible were diagnosed. There were no known drug allergies. The patient reported no previous difficulty with anesthesia, as well as no known prior adverse reactions to anesthesia in any relatives. The planned surgical intervention was open reduction-internal fixation of bilateral mandibular fractures. The patient received succinylcholine and desflurane during the procedure. A full 70 minutes elapsed before initial signs of hypermetabolism were noted, namely a rise in end-tidal carbon dioxide level. The patient received dantrolene sodium approximately 120 minutes after induction of anesthesia. Signs of hypermetabolism began to abate within 45 minutes of commencement of the malignant hyperthermia treatment protocol. He was subsequently transferred to the surgical intensive care unit for continued management and had a favorable postoperative course. This case underscores the importance of awareness of malignant hyperthermia and its presentation. This condition carries a potential high risk of complications after exposure to triggering anesthetic agents. Taking a complete and detailed history may help to identify potential cases. In this case, it was subsequently discovered that the patient's biological sister had a nearly fatal reaction to general anesthesia several years before this incident. Intraoperative vigilance in the monitoring of vital signs cannot be overemphasized. An increase in end-tidal carbon dioxide values, in addition to other clinical signs that cannot be easily attributed to other causes, should increase the clinical index of suspicion for a diagnosis of malignant hyperthermia.

Office computer systems for the dental office.

The role of computers in dental practice has dramatically changed over the past 30 years. We have witnessed the progression from administrative roles to complete integration leading to chartless offices. As the dental community gradually adopts this contemporary development, the move to electronic health records is imminent because of upcoming changes in the health care system. The past, present, and future of dental office computer systems is explored in this article. An understanding of the benefits and current challenges of contemporary dental practice software is also reviewed.

Technological advances in nontraditional orthodontics.

New technological advances have helped the orthodontic profession progress in traditional and surgical methods of treatment. The profession has seen transitions from traditional braces to self-ligating brackets, lingual braces, removable aligners, and more advanced technology, which have helped to address concerns that include but are not limited to better diagnostics, anchorage control, length of treatment, and esthetics. An increase in the number of adult patients seeking orthodontic treatment and the need for a timely efficient care will continue to drive technology and the use of cone beam computed tomography, miniscrews, piezocision, distraction osteogenesis, and bioengineering.
