Her respiratory condition was so bad that she needed to be intubated and put on artificial respiration. After her consciousness and respiratory condition gradually recovered, we noticed that she had developed a bilateral hearing loss. The auditory brain stem response test revealed only I waves on both sides, thus suggesting that her hearing loss had been caused by an injury to the hearing-conducting pathway including the cochlear nuclei. In this case, the hematoma extended from the lower to the upper part of pons and, furthermore, it was also located broadly in the dorsal part of the pons. As a result, the cochlear nuclei and corpus trapezoideum appeared to have been destroyed by the hematoma. However, since most cases with a brain stem hemorrhage showing bilateral hearing loss tend to be in a severe condition, this condition is often easy to overlook. We should therefore carefully evaluate patients’ reaction to hearing stimulation to avoid overlooking any hearing loss in such patients.展开更多

Audiometric testing under headphones confirmed a reversible, moderate unilateral hearing loss. Under binaural listening conditions, auditory comprehension was impaired at the same site, whereas word repetition, environmental sound recognition, naming, and spontaneous speech remained intact.展开更多

Study design: A cohort of 76 infant s with congenital cytomegalovirus (CMV) infection identified by means of newborn virologic screening was monitored for outcome. The amount of infectious CMV was analyzed in urine specimens obtained during early infancy. Peripheral blood (PB ) samples obtained during early infancy were available from 75 children and CMV DNA was quantitated with a real-time quantitative polymerase chain reaction. Re sults: Infants with clinical abnormalities at birth (symptomatic congenital CMV infection) had higher amounts of CMV in urine (P =. 005) and CMV DNA in PB (P =. 001) than infants with no symptoms. Eight children with and 4 children without symptoms had hearing loss. Among children without symptoms, those with hearing l oss had a significantly greater amount of CMV in urine (P =. 03) and PB virus bu rden (P =. 02) during infancy than those with normal hearing. Infants with < 5 ×103 pfu/mL of urine CMV and infants with < 1 ×104 copies/mL of viral DNA in P B were at a lower risk for hearing loss. Conclusion: In children with asymptomat ic congenital CMV infection, hearing loss was associated with increased amounts of urine CMV and PB CMV DNA during early infancy.展开更多

Audiometric testing revealed five (22.7%) with unrecognized sensorineural hearing loss; however,on genetic evaluation,none harbored a connexin 26 mutation.展开更多
