conclusion we concluded that cmv is the most common cause of intrauterine infection in infants aged less than 6 months as compared to the healthy ones. we prefer, at least in our country, to consider seropositive (cmv-igm) infants suspected of intrauterine infection (less than 6 months) as congenital form. to arrest the natural progression of congenital cmv, we recommend prolonged course of ora...

Sensorineural hearing loss (SNHL) is the most common congenital deficit. As non genetic contributions congenital cytomegalovirus infection (cCMV) is the most frequent cause for this disease. In 10% 20% of patients with sensorineural hearing loss intrauterine infection with cytomegalovirus is diagnosed. Hearing impairment due to CMV can be diagnosed at birth; nevertheless 33% 50% is late-onset l...

Introduction: Hearing impairment is the most frequent sensorial congenital defect in newborns and has increased to 2–4 cases per 1,000 live births. Sensory-neural hearing loss (SNHL) accounts for more than 90% of all hearing loss. This disorder is associated with other congenital disorders such as renal, skeletal, ocular, and cardiac disorders. Given that congenital heart diseases are life-thre...

This article is the second in a 2-part series reviewing neuroimaging in childhood SNHL. Previously, we discussed the clinical work-up of children with hearing impairment, the classification of inner ear malformations, and congenital nonsyndromic causes of hearing loss. Here, we review and illustrate the most common syndromic hereditary and acquired causes of childhood SNHL, with an emphasis on ...

OBJECTIVE To ascertain the present common causes of sensorineural hearing loss (SNHL) in children and compare them with those of previous reports. DESIGN A retrospective review of the medical records for all children with a diagnosis of SNHL seen from January 1, 1993, through September 30, 1996, at our institution. SETTING A tertiary care children's hospital. PATIENTS Three hundred one ch...

various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution ct scan. it was found that in approximately one third of the patient group (with idiopathic snhl), the vestibular aqueduct was 1.5 mm or larger. also...

Although conventional structural MRI provides vital information in the evaluation of congenital sensorineural hearing loss (SNHL), it is relatively insensitive to white matter microstructure. Our objective was to evaluate possible changes in microstructure of the auditory pathway in children with congenital sensorineural hearing loss (SNHL), and the possible distinction between good and poor ou...

Abstract Cytomegalovirus (CMV) is the most common congenital viral infection in developed world and leading cause of non-genetic sensorineural hearing loss (SNHL) children. Congenital CMV causes progressive SNHL long after acute has resolved, suggesting a lasting effect on developing host immune response cochlea. Using fate-mapping models, we investigated contribution fetal-derived resident tis...
