With electronystagmography (ENG), various tests were carried out in 16 patients of congenital and 10 patients of acquired nystagmus. The results indicated that the two groups manifested distinct differences in gaze nystagmus, responses of saeeade and eye tracking, and optokinetic nystagmus. It is believed that the ENG can help make objective differential diagnoses between the two kinds of nystagmus.

OBJECTIVE Analyzing the psychological performance of patients with presbycusis before and after fitting hearing aids.METHODS Analyzing the psychological performance of the patients in different levels by using the oral negotiation and the modified self-symptoms inventory(symptom check-list-90, SCL-90), including the cognition condition of the senile patients after fitting hearing aids.RESULTS 126 presbycusis patients performed in 4 psychological ways including ignorance, worry, depression and autism tendency.The presbycusis patients had cognition deviation after fitting hearing aids.It showed that they were hoping for quick success, having high expectations and antipathy to the hearing aids.CONCLUSION Fully understanding the gerontal patients' abnormal psychological performances and cognition deviations to the hearing aids can help us to enhance the early intervention and hearing rehabilitation.

Objective To analyze the clinical and MR features of intracranial nonspecific inflammatory granuloma and improve the accuracy of preoperative diagnosis.Methods The clinical and MR features of 9 intracranial nonspecific inflammatory granuloma cases proved by histopathology were analyzed retrospectively.Results Nine lesions were all located in the supratentorial cerebral hemisphere with large lesion range and obvious peripheral edema.On enhancement MR imaging,the lesions were obviously and irregularly enhanced.There were simple patchy enhancement in 3 cases,patchy enhancement with multiple micronodular enhancement in 4 cases,and multiple micronodular enhancement in 2 cases.None enhancement areas were noticed in all enhancement lesions.There were superficial meningeal enhancements in 4 cases.On MR plain scanning,the MR enhancement area of lesions showed similar signal to the grey matter on T1 WI and low signal similarly to the white matter on T2 WI.On MRS scan,the significant high signal of Cho was detected in 2 cases and their Cho/Cr ratio was over 4.The Cho/Cr ratio was lower than 1.3 in 5 cases.Conclusion There are some specific MR enhancement features in the intracranial nonspecific inflammatory granuloma including multiple small nodules or patchy enhancement,in which there were no enhancement areas,and some cases have meningeal enhancement.
