Thalassemia review: features, dental considerations and management.

Thalassemia is a genetic disorder that involves abnormal haemoglobin formation. The two main categories of thalassemia are alpha and beta thalassemia that are then divided into further subcategories. While some mild forms of thalassemia might even go unnoticed and only cause mild anaemia and iron deficiency problems in patients, other more severe forms of thalassemia can even result in death.

Cone Beam Computed Tomography Analysis of Upper Airway Measurements in Patients With Obstructive Sleep Apnea.

Purpose: To explore the validity of cone beam computed tomography (CBCT) as one of many predictive tools that can be used (alone or in conjunction) to help in identifying high-risk cases of obstructive sleep apnea (OSA) that should get the earliest possible referral to a sleep specialist for standard diagnostic polysomnography, and to identify imaging airway parameters that may be predictive of OSA severity.

Methods: Using a case-control design, 45 subjects matched by age and sex (22 OSA cases and 23 controls) were included in this study. Subjects were assigned as cases depending on a sleep study with apnea-hypopnea index (AHI)>5 and as controls depending on a Berlin questionnaire score identifying low risk or no risk of OSA.
