STUDY OBJECTIVE The purpose of the study was to assess the accuracy of Family Practitioner Committee (FPC) lists for identifying very elderly people registered with general practitioners. DESIGN The accuracy of available FPC lists was checked against the most recent electoral register to determine which recorded individuals were still living at their FPC registered addresses. This was followe...
INTRODUCTION Auricular Arteriovenous Malformation of the external ear is a rarely encountered disease; in particular, arteriovenous malformation arising from the auricle, with spontaneous bleeding, has seldom been reported. OBJECTIVE In the current study, we report an unusual case of late-onset auricular arteriovenous malformation originating from the posterior auricular artery that was confi...
The literature regarding arteriovenous malformations of the external ear is sparse. A case of a patient clinically diagnosed with an arteriovenous malformation of the external ear that was managed empirically with surgical excision, without recurrence, is presented. The pathogenesis, clinical presentation, radiological work up and management options regarding arteriovenous malformations are rev...
The inner ear is a highly specialized mechanosensitive organ responsible for hearing and balance. Its small size and difficulty in harvesting sufficient tissue has hindered the progress of molecular studies. The protein components of mechanotransduction, the molecular biology of inner ear development and the genetic causes of many hereditary hearing and balance disorders remain largely unknown....
MANDIBULO-FACIAL dysostosis is the name given by Franceschetti and Zwahlen (1944) and Franceschetti and Klein (1949) to a complex of symptoms which together comprise a congenital oro-facial syndrome (Wildervanck, 1960). Franceschetti and Klein (1949) reviewed the literature and described the typical characteristics of the syndrome as follows: (1) Antimongoloid palpebral fissures with either a n...
Due to the physics of magnetic fields and forces, any single magnet will always attract or pull-in magnetically-responsive particles. However, there are a variety of clinical needs where it is advantageous to be able to push away or ‘magnetically inject’ therapeutic particles. Here we focus on magnetic injection to treat inner-ear diseases. The inner ear is behind the blood-ear barrier, meaning...
INTRODUCTION Congenital abnormalities of the inner ear is the most common cause of neurosensory hearing loss. Michel inner ear deformity is a rare developmental anomaly refers to the total aplasia of the inner ear. It is caused by developmental arrest of otic placode early during the third week of gestational age. CASE REPORT We have discussed here that three year old girl diagnosed Michel ap...
BACKGROUND Congenital cytomegalovirus (CMV) infection is a leading cause of sensorineural hearing loss (SNHL). The mechanisms of pathogenesis of CMV-related SNHL are still unclear. The aim is to study congenital CMV-related damage in the fetal inner ear, in order to better understand the underlying pathophysiology behind CMV-SNHL. RESULTS We studied inner ears and brains of 20 human fetuses, ...
