Extensive maxillary odontogenic keratocyst: review of the literature and report of a case.

Odontogenic keratocysts arising in the maxilla are relatively uncommon, small unilocular lesions that rarely involve the maxillary sinus. This paper reviews the clinical, radiologic and histologic features of an extensive maxillary odontogenic keratocyst involving the maxillary sinus, and the complications associated with its management. The authors emphasize the importance of regular patient follow-up examinations and imaging studies in order to detect and treat recurrent lesions when they are small and well-localized.

Life in the universe.

We comprehend the universe and our place in it. But there are limits to what we can explain at present. Will research at the boundaries of science reveal a special role for intelligent life?

Erythroid progenitor (BFU-E, CFU-E) proliferation as inferred from 5'bromodeoxyuridine labeling.

Survival patterns of burst-forming unit-erythroid (BFU-E) and cluster-forming unit-erythroid (CFU-E) were studied in B6D2F1 mice after 5'bromodeoxycytidine (BrdCyd) infusion and near-ultraviolet (near-UV) light treatment. Comparison of the kinetics of BrdCyd sensitization of these colony formers with the kinetics of granulocyte-monocyte colony-forming cells (GM-CFC) and colony-forming unit-spleen (CFU-S) demonstrated a similar, but distinguishable, pattern of labeling between BFU-E and CFU-S. BFU-E and CFU-S each contain a subpopulation of unlabeled cells that diminishes with a half-life of 35 to 40 hours. Subsequent comparisons of this close association of BFU-E and CFU-S in Sl/Sld mice, again, showed similar patterns of BrdCyd labeling without evidence of an unlabeled or G0 subpopulation. These results are discussed with respect to the likelihood of a precursor relationship between these two cell types.

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.

Disseminated histoplasmosis with embolic endovascular complications: a case report.

A 57-year-old man had subacute embolic ischemia of his right foot and subsequent acute embolic ischemia of his left foot after angiography. Thrombus removed at the time of the left femoral thromboembolectomy grew Histoplasma capsulatum confirming the diagnosis of disseminated histoplasmosis. Surgical revascularization of the right leg and parenteral amphotericin B was followed by chronic ketoconazole therapy for 16 months. The patient has remained asymptomatic at 30 months after operation. Effective treatment of endovascular infection with ischemic complications of Histoplasmosis requires surgical revascularization and intensive chemotherapeutic intervention. Histoplasmosis is a ubiquitous infection in endemic areas that often has an asymptomatic subclinical course. Involvement of the cardiovascular system is rarely reported. Previous case reports have described infected cardiac valves and aortic aneurysms. This report describes the uncommon presentation of disseminated Histoplasma capsulatum infection as a peripheral embolic event and the successful management with revascularization combined with systemic amphotericin B followed by ketoconazole therapy.
