Facial nerve function following temporomandibular joint surgery using the preauricular approach.

Sixty-eight patients (83 temporomandibular joints) consecutively operated on who had a variety of temporomandibular joint operations using a preauricular approach were assessed for facial nerve function following surgery. Nine patients (10.84%) showed signs of facial nerve injury in which the temporal and zygomatic branches were involved. The incidence of facial nerve injury was greater in patients who had undergone previous temporomandibular joint surgery (17.64%) than in patients with previously unoperated joints (9%). Normal facial nerve function returned in 9 to 14 weeks except in one patient who showed a mild deficit of the zygomatic branch at 20 weeks. The nature and duration of the surgical procedure did not correlate with facial nerve injury. Scarring of tissues as a result of previous temporomandibular joint surgery may significantly increase the risk of facial nerve injury during subsequent temporomandibular joint surgery.

Rembrandt toothpaste stain prevention with and without the use of Peridex.

Sixty-five subjects were assigned to use Crest or Rembrandt dentifrice with either a placebo or Peridex rinse for eight weeks. One group, using Peridex, started with Crest and switched to Rembrandt at week four of the study. There were no significant differences among the groups on gingivitis, plaque, or calculus by the conclusion of the study. On the stain intensity index there was a significant statistical difference on buccal surfaces between Crest and Rembrandt with placebo compared to Crest with Peridex. On lingual surfaces, Rembrandt with placebo rinse was significantly lower than all Peridex rinse groups by the end of the study. From baseline to the conclusion of the study, Crest with placebo had no change in stain intensity, while Rembrandt with placebo had a significant drop on both buccal and lingual surfaces. The Peridex groups had increases on buccal stain intensity. On stain area scores, by the conclusion of the study both Crest and Rembrandt with placebo were significantly different from Crest with Peridex on buccal and lingual surfaces. Over time there was no significant change in stain area for the Crest with placebo groups. Rembrandt and placebo was significantly lower on stain area from baseline to week eight on buccal surfaces. The Peridex groups had increases in stain area over the study period.

Congenital unilateral ichthyosis in a newborn.

Ichthyosiform erythroderma is a rare phenomenon occurring in about 1/300,000 live births. Congenital unilateral ichthyosis, described in this case report, is a clinical variant of ichthyosis. Only five previous cases have been reported. In the patient described in this report, superimposed infection of the affected skin developed. Her immunologic system was intact. She manifested failure to thrive, in spite of an adequate caloric intake, and markedly delayed psychomotor development. This patient also demonstrated absorption from the affected dermis of topically applied urea hydrophilic base ointment. She died before her first birthday.

Duration of hospitalization in "uncomplicated completed acute myocardial infarction". An Ad Hoc Committee review.

The clinical and laboratory findings diagnostic of acute myocardial infarction include at least two of the following: (1) a history of pain consistent with myocardial ischemia, (2) electorcardiographic findings consistent with infarction, and (3) a rise in the serum level of specific cardiac enzymes. By the 4th or 5th day of illness, specific criteria can be applied to assign certain patients to a subset with "uncomplicated completed acute myocardial infarction." These criteria include the absence of evidence of (1) continuing cardiac ischemia, (2) left ventricular failure, (3) shock, (4) important cardiac arrhythmias, (5) conduction disturbances, and (6) other serious illnesses in patients with an established acute myocardial infarction. In terms of prognosis and management, patients in this subset should be regarded as substantively different from patients in other subsets. They should respond favorably to short periods of immobilization and hospitalization than those generally used. They may remain at bed rest (modified in regard to sitting and the use of a commode) for 4 days. Subsequently, mobilization with a program of progressive activity over the ensuing 5 to 10 days should reduce the duration of hospitalization to less than the current average of 17.5 to 20.8 days for patients with acute myocardial infarction. Nine to 14 days should suffice in most instances. Current and future trials may indicate that still earlier mobilization and shorter hospitalization periods can be applied to certain patient groups, but the evidence on this point is incomplete. For the individual patient, many factors will determine the optimal duration of bed rest and hospital stay. The patient's physician must consider the therapeutic benefits that may attend earlier mobilization and shorter hospitalization while weighing potential disadvantages. When the responsible physician does not regularly care for the patient, consultation with an experienced cardiologist is desirable. Patients whose condition is classified as "uncomplicated" may manifest deterioration during their illness and require assignment to a subset with a different prognosis and requiring different forms of treatment. For patients with uncomplicated acute myocardial infarction, as well as those in other subsets, absolute rules for therapy are unwise and application of broader principles by the alert physician is more likely to be beneficial.

Simplified technique to reduce perioral edema in intraoral sagittal split osteotomies.

A simplified technique has been developed for the prevention of the severe perioral edema that is routinely associated with intraoral sagittal split osteotomies of the ascending ramus of the mandible. By the use of gauze sutured through the cheeks in the region of the oral commissures, trauma caused by retraction of instruments is significantly diminished.
