Temporomandibular joint alloplastic replacement failure.

Temporomandibular joint disorders are common, with alloplastic temporomandibular joint replacement (TMJR) being one method of addressing chronic pain and movement limitations that cannot otherwise be managed. Despite this, TMJR has known complications that can lead to failure. We present our experience of managing these cases and review the current evidence on the management and outcomes of alloplastic TMJR failures.

Injuries to the head and neck in Homer's Odyssey.

The Odyssey and the Iliad are the most prominent works of ancient Greek epic poetry, and we have retrieved injuries to the head and neck mentioned in the Odyssey. We studied the texts both in ancient Greek and the translations in modern Greek and English and searched for references to trauma to the head and neck. We recorded the injuries, the attacker and defender, the weapons used, the site, and the result.

Positive predictive value of clinical diagnosis of head and neck non-melanoma skin malignancies. How accurate are we?

Unlabelled: ᅟ: The purpose of the current study was to determine the accuracy of the clinical diagnosis in non-melanoma skin malignancy as confirmed by histopathological examination of the specimen. Positive predictive value (PPV) was selected as a reliable measure of diagnostic accuracy.

Methods: Clinical diagnosis was made in the outpatient clinic by a consultant oral and maxillofacial surgeon.

Multivariate modeling of encapsulation and release of an ionizable drug from polymer microspheres.

In the formulation of polymer microspheres (MSs) loaded with verapamil hydrochloride (VRP), a low molecular weight ionizable drug, by W/O/W emulsification, the pH of the external aqueous phase proved to be a primary determinant of both IE and drug release behavior. Increasing the pH of the external aqueous phase enhanced IE (approximately 100% at pH 8.4).
