Preprosthetic Surgery-Narrative Review and Current Debate.

This review describes the role of modern preprosthetic surgery. The atrophic edentulous jaw can cause severe functional impairment for patients, leading to inadequate denture retention, reduced quality of life, and significant health problems. The aim of preprosthetic surgery is to restore function and form due to tooth loss arising from congenital deformity, trauma, or ablative surgery.

Computer assisted diagnosis of Alzheimer's disease using statistical likelihood-ratio test.

The purpose of this work is to present a computer assisted diagnostic tool for radiologists in their diagnosis of Alzheimer's disease. A statistical likelihood-ratio procedure from signal detection theory was implemented in the detection of Alzheimer's disease. The probability density functions of the likelihood ratio were constructed by using medial temporal lobe (MTL) volumes of patients with Alzheimer's disease (AD) and normal controls (NC).

Graeme Warrack: oral surgeon and war hero.

This paper describes the heroic efforts of Graeme Warrack, an oral surgeon, to save as many lives as possible during the battles around Arnhem in 1944. As the chief medical officer (CMO) of the medical section of the 1st British Airborne Division, he and his staff took care of many casualties, both on the battlefield and at the emergency hospital in Apeldoorn, north of Arnhem. He escaped from the hospital when all the patients were to be transported to prisoner of war (POW) camps in Germany, and was hidden by a Dutch family.

Onlay bone grafts from iliac crest: a retrospective analysis.

This study was performed to address the outcomes of patients treated with onlay grafts from the iliac crest to augment the deficient jaw. The results of 173 consecutive patients who underwent bone grafting prior to implant surgery are presented. The grafts were taken from the anterior iliac crest to repair alveolar bone deficiencies that were too large to be corrected using intraoral bone grafts.

Environmental factors influencing participation of stroke survivors in a Western Cape setting.

Background: Environmental factors compound or diminish the effects of impairments; therefore they have a direct influence on participation of stroke survivors.

Objectives: To determine environmental barriers and facilitators to participation experienced by a group of stroke survivors in the Western Cape province of South Africa.

Methods: A descriptive, mixed methods study was conducted in 2011.
