UNLABELLED Frontonasal dysplasia (FND) is a rare malformative complex affecting the frontal portion of the face, the eyes and the nose; it may occur singly or associated with other clinical signs. No systematic studies describing hearing in this condition were found. AIM To evaluate hearing sensitivity and sound stimulus conduction from cochlea to brainstem in patients with clinical signs of ...

The causes, and characteristics of hearing-impairment were determined prospectively among six thousand, four hundred and twenty-eight (6,428) patients who reported at the Komfo Anokye Teaching Hospital (KATH) with hearing problems. The purpose of the study was to determine the characteristics and some causes of hearing loss of patients who report for management at Komfo Anokye Teaching Hospital...

BACKGROUND Hearing disorders have been associated with occupational exposure to music. Musicians may benefit from non-amplified and low-intensity music, but may also have high risks of music-induced hearing loss. AIMS To compare the incidence of hearing loss (HL) and its subentities in professional musicians with that in the general population. METHODS We performed a historical cohort study...

The perinatal necropsy is an important investigation following fetal or neonatal loss. Legal requirements on registration decree that consent is needed before necropsy can proceed in some of these babies. However, there are ill-defined grey areas which are open to legal and ethical difficulties. This paper discusses the problems that can arise with consent for a necropsy in the perinatal period...

The bone-conduction (BC) tone ABR has been used clinically for over 20 years. The current study formally evaluated the test performance of the BC tone-evoked ABR in infants with hearing loss. Method. By comparing BC-ABR results to follow-up behavioural results, this study addressed two questions: (i) whether the BC tone ABR was successful in differentiating children with conductive versus senso...

Dear Sir, We believe the article by Clements et al. in the May issue of the JLO to be misleading, in suggesting that the improvement in sensorineural hearing loss in Wegener's granulomatosis treated with combined cytotoxicimmunosuppressive therapy is an unusual finding. In the discussion they state there has been only one similar report (Peiterson and Carlsen, 1965). However, we should like to ...

The effects of consanguineous marriages in various isonymic groups have been investigated. The families like Qureshi, Malik, Jats and Sheikh show higher live-births, prenatal and postnatal loss, and percentage pregnancies in the first cousin and 'all related' parental relationships compared to other groups. Syed, Butt, and Mughals show higher percentage of prenatal and postnatal loss, livebirth...

In this paper, we have developed a new prototype of 0.5 hp induction motor with reduced slots in rotor bar and stator core in comparison to the conventional induction motor. The conventional induction motor usually uses 30 slots of aluminum rotor bar and 36 slots in the stator core. In our developed prototype, we used 10 slots of copper rotor bar and 24 slots in the stator core. In order to eva...

Normal hearing requires exquisite cooperation between bony and sensorineural structures within the cochlea. For example, the inner ear secretes proteins such as osteoprotegrin (OPG) that can prevent cochlear bone remodeling. Accordingly, diseases that affect bone regulation can also result in hearing loss. Patients with fibrous dysplasia develop trabecular bone overgrowth resulting in hearing l...

introduction: although the incidence and prevalence of chronic suppurative otitis media (csom) has been decreased in recent decades, but it is still a major health problem in both developing and developed countries. csom can cause major and life-threatening complications such as hearing loss, meningitis and cerebral abscess. since hearing loss is the most common complication of csom, we aimed t...
