Three Years of Vestibular Infant Screening in Infants With Sensorineural Hearing Loss.

OBJECTIVES: Although vestibular deficits are more prevalent in hearing-impaired children and can affect their development on many levels, a pediatric vestibular assessment is still uncommon in clinical practice. Since early detection may allow for timely intervention, this pioneer project has implemented a basic vestibular screening test for each six-month-old hearing-impaired infant in Flanders, Belgium. This study aims to report the vestibular screening results over a period of three years and to define the most important risk factors for abnormal vestibular screening results. METHODS: Cervical Vestibular Evoked Myogenic Potentials with bone-conduction were used as a vestibular screening tool in all reference centers affiliated to the Universal Newborn Hearing Screening Program in Flanders. From June 2018 until June 2021, 254 infants (mean age: 7.4 months, standard deviation: 2.4 months) with sensorineural hearing loss were included. RESULTS: Overall, abnormal vestibular screening results were found in 13.8% (35 of 254) of the infants. The most important group at risk for abnormal vestibular screening results were infants with unilateral or bilateral severe to profound sensorineural hearing loss (20.8%, 32 of 154) (P < .001, odds ratio = 9.16). Moreover, abnormal vestibular screening results were more prevalent in infants with hearing loss caused by meningitis (66.7%, 2 of 3), syndromes (28.6%, 8 of 28), congenital cytomegalovirus infection (20.0%, 8 of 40), and cochleovestibular anomalies (19.2%, 5 of 26). CONCLUSIONS: The vestibular screening results in infants with sensorineural hearing loss indicate the highest risk for vestibular deficits in severe to profound hearing loss, and certain underlying etiologies of hearing loss, such as meningitis, syndromes, congenital cytomegalovirus, and cochleovestibular anomalies.

Vestibular Infant Screening (VIS)-Flanders: results after 1.5 years of vestibular screening in hearing-impaired children.

Due to the close anatomical relationship between the auditory and vestibular end organs, hearing-impaired children have a higher risk for vestibular dysfunction, which can affect their (motor) development. Unfortunately, vestibular dysfunction often goes unnoticed, as vestibular assessment in these children is not standard of care nowadays. To timely detect vestibular dysfunction, the Vestibular Infant Screening-Flanders (VIS-Flanders) project has implemented a basic vestibular screening test for hearing-impaired infants in Flanders (Belgium) with a participation rate of 86.7% during the first year and a half. The cervical Vestibular Evoked Myogenic Potentials (cVEMP) test was applied as vestibular screening tool to map the occurrence of vestibular (mainly saccular) dysfunction in this population. At the age of 6 months, 184 infants were screened. No refers on vestibular screening were observed in infants with permanent conductive hearing loss. In infants with permanent sensorineural hearing loss, a cVEMP refer rate of 9.5% was observed. Failure was significantly more common in infants with severe-profound compared to those with mild-moderate sensorineural hearing loss (risk ratio = 9.8). Since this is the first regional study with a large sample size and successful participation rate, the VIS-Flanders project aims to set an example for other regions worldwide.

Postoperative radiotherapy for adenocarcinoma of the ethmoid sinuses: treatment results for 47 patients.

PURPOSE: Ethmoid sinus cancer is a rare malignancy. Treatment results are mostly reported together with other sinonasal tumors, grouping a wide range of different histologies and treatment approaches. This study reports on the treatment outcome of 47 patients diagnosed with adenocarcinoma of the ethmoid sinuses and treated with surgery and high-dose postoperative radiation therapy. METHODS AND MATERIALS: Between September 1985 and October 2001, 51 patients with adenocarcinoma of the ethmoid sinuses were referred to the Ghent University Hospital. Four patients were treated with low-dose palliative radiation because of very extended inoperable disease or distant metastasis at the time of diagnosis. They were not included in this analysis. The other 47 patients, all staged as N0M0, were treated with surgery and postoperative high-dose radiation therapy. The median follow-up was 32 months. The T-stages were T1 for 2, T2 for 17, T3 for 11, and T4 for 17 patients. All 47 patients were staged as N0M0. RESULTS: The 3-year, 5-year, and 7-year overall survival are respectively 71%, 60%, and 38%. The 3-year and 5-year disease-free survival are respectively 62% and 36%. The 3-year and 5-year disease-free survival for T1-T2 stages are respectively 87% and 55%, for T3 stages 57% and 28%, and for T4 stages 41% and 25%. The locoregional tumor control was 70% and 59% at respectively 3 and 5 years. Patients presenting with intracranial tumor invasion at the time of diagnosis relapsed within 7 months after the end of radiotherapy. Radiation-induced severe dry eye syndrome and optic neuropathy was observed in respectively 7 and 2 of the 47 cases. CONCLUSION: Postoperative radiotherapy for adenocarcinoma of the ethmoid sinuses is associated with good local control rates. Crucial for a favorable prognosis is the absence of intracranial invasion. The rarity of these tumors makes it difficult to evaluate new therapeutic advances.
