Predictive value of P wave parameters, indices, and a novel electrocardiographic marker for silent cerebral infarction and future cerebrovascular events.

Background: Silent cerebral infarction (SCI) is a neuronal injury without a clinically apparent stroke or transient ischaemic attack. Left atrial cardiomyopathy is closely associated with SCI. P wave changes in the electrocardiogram (ECG) provide significant information about the development of atrial cardiomyopathy.

The Effects of Superficial Musculoaponeurotic System Flap on the Development of Frey's Syndrome and Cosmetic Outcomes After Superficial Parotidectomy.

Isotretinoin is widely used in the treatment of extensive and nodulocystic acne. The objective of this prospective study was to investigate whether oral isotretinoin could affect the hearing system. Thirty-eight patients with acne vulgaris (76 ears) who were diagnosed and treated at the Department of Dermatology were included in the current study.

Investigation of hearing in patients with allergic rhinitis.

The aim of the current study is to investigate hearing function in patients with allergic rhinitis. Fifty-eight patients with positive skin prick test (Group 1) (116 ears) and 31 subjects with negative skin prick test (62 ears) as group 2 were included. Pure tone audiometry at 250, 500, 1000, 2000, 4000 and 8000 Hz and immittance measures, including tympanometry and acoustic reflex tests, were performed in both groups.

Bilateral acquired external auditory canal stenosis with squamous papilloma: a case report.

Acquired external auditory canal (EAC) stenosis is described as resulting from a number of different causes such as infection, trauma, neoplasia, inflammation and radiotherapy. Human papilloma virus (HPV) type 6, a deoxyribonucleic acid (DNA) virus, is considered to cause squamous papilloma of the EAC. In this article, we report a case of a 56-year-old male with warty lesions in the left external ear and a totally stenotic right external ear which had similar lesions one year before the involvement of his left ear.

Audiological findings in celiac disease.

Objective: Celiac disease (CD) is a gluten-triggered immune enteropathy caused by a genetic predisposition. Recent papers suggest that CD is increasingly recognized by extraintestinal findings. The aim of this study was to investigate the effect of CD on hearing pathway including the olivocochlear efferent system in children.

Sensorineural hearing loss in pediatric celiac patients.

Objective: Celiac disease (CD) is an immune-mediated chronic inflammatory gluten-dependent intestinal disease affecting 0.5-1% of the general population worldwide. CD is underdiagnosed even with sophisticated health care; approximately 10% of people affected by CD are now diagnosed.

Expression of histamine receptors (H(1), H(2), and H(3)) in the rabbit endolymphatic sac: an immunohistochemical study.

Objective: The endolymphatic sac (ES) is part of the membranous labyrinth of the inner ear. Its central role in immunologic activity within the inner ear has been confirmed by numerous studies.

An alternative model for stapedectomy training in residency program: sheep cadaver ear.

To determine the usefulness of sheep cadaver ear as a complementary model for training of stapedectomy at residency programs, 2 of our 4 year residents were included in the study and each operated 20 sheep ears. All routine steps of stapedectomy operation were performed, and their success and complication scores were recorded. Performance of residents for stapedectomy and teflon piston placement in sheep ears were evaluated by the authors.
