[Analysis on voice acoustic parameters and electroglottographic parameters in normal children of Han, Naxi, Bai nationality].

OBJECTIVE: To explore the normal vocal acoustic parameters and electroglottographic (EGG) parameters and their differences in normal children of the Han, the Naxi, the Bai nationality. METHOD: By using computer and Dr. speech software, We studied six parameters of voice acoustic and the E.G.G. in 951 children (Han 342, Naxi 224, Bai 385), aged 4-8 years old. We also examined 30 cases who suffered from vocal nodule and local proliferation. RESULT: The major parameters 1. Jitter, 2. Shimmer, 3. Mean F0, 4. SD F0, 5. NNE) of the voice acoustic and E.G.G. of the three nationality. CONCLUSION: 1. All parameters in Han nationality school-age children and preschool children were not different in years old. But Naxi and Bai nationality school-age children's Mean F0 and SD F0 were different from preschool children. The parameters(Mean F0, SD F0) of school-age children in Han, Naxi and Bai nationality were significant different. 2. The tested parameters were significant different between normal children of the Han nationality and the vocal nodule patients.

[Observation of deaf-mute students' audition examine and otacoustic effect].

OBJECTIVE: To explore the state of the remnant hearing of deaf-mute students and to check the effect of hearing aids to them. METHOD: 38 cases of deaf and dumb students were examined with the pure tone auditometry, acoustic immitance test, auditory brainstem response, and the environmental sound discrimination test. RESULT: In 17 cases, the average threshold of air conduction of speech frequency is below 89 dB HL; In 18 cases, it is between 90 dB and 110 dB; In 3 cases, it is above 110 dB. 33 cases have model A curve and 5 cases have model B curve. When 123 dB peSPL was presented, 24 cases generated the waveform but the others didn't. 16 cases could discriminate the environmental sound and the other 22 cases could not, but if the patients weared the hearing aids, the number of the persons who could discriminate the environmental sound increased to 24, only 14 cases had no effect by this means. CONCLUSION: Examination of deaf-mutes audition can find persons with residual audition. If they wear the hearing aids and go into hearing rehabilitation training at the same time as early as possible, it will improve the environmental sound discrimination rate.

Cutaneous infection by Scedosporium apiospermum and its successful treatment with itraconazole.

We report the case of a 42-year-old man with a 13-year history of bilateral faciocervical infiltrative erythema, which had been misdiagnosed as tuberculoderma and which had failed to respond to treatment with adrenal corticosteroids and antituberculotics. On admission to the department, Scedosporium apiospermum was identified on lesion biopsies and fungus cultures as the causative agent and a diagnosis of cutaneous infection by S. apiospermum was made. This is the first report of chronic skin granuloma caused by S. apiospermum in China. Treatment with oral itraconazole (100-400 mg/day) led to clinical cure within 4 months.

[A survey of antibodies to arboviruses in residents in south-western part of Yunnan province].

In order to provide serological evidence for arbovirus infection in Yunnan province, 760 Samples of human sera collected from nine counties in south-western part of Yunnan province were examined for HI antibodies to 11 arboviral antigens. The viruses used in this experiment included 3 alphaviruses (MAY, VEE and CHIK) and 8 flaviviruses (JE, MVE, KUN, DEN3, DEN4, KFD, LGT and POW). 275 samples were found positive for HI antibodies to alphaviruses (36.2%) and 189 of them (68.7%) reacted with MAY virus, 61 (22.2%) with CHIK. The GMT of HI titers for VEE, MAY and Chik were 164.4, 94.5 and 66.7, respectively. 588 samples of sera (77.4%) were found positive for HI antibodies to flaviviruses. The positive HI antibody rates were as follows: JE, 27.9%; DEN, 36.6%; KFD, 22.2%; MVE, 22.1%; KUN, 18.7%; POW, 8.8% and LGT, 7.9%, respectively. Its average GMT was 356, and the antibody titers of 403 samples of sera were higher than 1/640. Cross reactions among viruses, especially flaviviruses, were usually found by HI test, and superinfections were present. In addition to the existence of JE and DEN viruses the results clearly showed that many Kinds of arboviruses might exist in Yunan Province.
