The perception of meaningfulness and performance of instrumental activities of daily living from the perspectives of the medically at-risk older adults and their caregivers.

The purpose of the study was to understand the impact of chronic disability on the functional ability of older adults. Thirty older adult participants and their caregivers were asked to identify which instrumental activities of daily living (IADL) are most meaningful and how their disability affected performance. Data collected through individual analysis indicated that the most important IADL tasks were driving and managing medication.

[Maxillary sinus septa. Prevalence and anatomy].

Background: Maxillary sinus septa may complicate sinus elevation procedures, especially when they are not diagnosed prior to surgery. The authors had for aim to review published data, to analyze the etiology, the prevalence, the localization, and the size of maxillary sinus septa, and to determine what were the best preoperative radiological examinations.

Patients And Methods: The Medline search was made with keywords such as "maxillary sinus anatomy, maxillary sinus augmentation, maxillary sinus septa, sinus graft/complications, dental implants".

Maxillary sinus vascular anatomy and its relation to sinus lift surgery.

Objectives: To investigate the prevalence, location, size and course of the anastomosis between the dental branch of the posterior superior alveolar artery (PSAA), known as alveolar antral artery (AAA), and the infraorbital artery (IOA).

Material And Methods: The first part of the study was performed on 30 maxillary sinuses deriving from 15 human cadaver heads. In order to visualize such anastomosis, the vascular network afferent to the sinus was injected with liquid latex mixed with green India ink through the external carotid artery.
