RESUMO
Objective To investigate the correlation between the mean platelet volume (MPV) ,neutrophil-to -lymphocyte(NLR) and the severity as well as prognosis of sudden sensorineural hearing loss (SSHL) patients . Methods A retrospective cohort study involved 172 patients with SSHL from January 2012 to May 2015 .The distri-bution characteristics of routine blood (white blood cells ,neutrophil ,lymphocyte ,MPV ,NLR) in different audio-metric curves (hearing loss at low frequencies ,flat type ,high frequencies ,and total deafness) and prognosis of re-covery (complete ,partial ,slight ,and no recovery )were analyzed by SPSS 19 .0 analysis chi square test ,and the prognosis was estimated by using the receiver operating characteristic curve (ROC) .Results MPV and NLR levels in the severe and profound hearing loss group were significantly higher than that in different audiometric curves (P<0 .01 and P<0 .01) .MPV and NLR level in the partial recovery group and the no recovery group were signifi-cantly higher than that in the complete recovery group (P<0 .01 and P<0 .01) .The value of the MPV and NLR showed negative correlation with the prognosis (hearing recovery ) ,and the lymphocyte was positive with the prog-nosis .The sensitivity and specificity of MPV and NLR count 24 hours after admission predicting the prognosis of hearing recovery were 66 .2％ and 85 .5％ ,58 .4％ and 86 .7％ ,respectively .Conclusion The changes of MPV and NLR in SSHL patients are related to the severity of hearing loss ,and NLR count at 24 hours after admission may play an important role in prognosis of this disease .
RESUMO
Solitary fibrous tumor (SFT) is a rare spindle cell neoplasm that usually develops in the pleura and peritoneum. The head and the neck region is involved in only 6% of the cases. We described a rare case of large SFT originated from the right neck region in a 32-year-old man. Enhanced CT scan revealed two large completely resected masses in the carotid sheath region and the right thyroid gland. Immunohistochemical studies showed positive CD34, CD99, NSE and bcl-2, and negative Desmin, NF, S-100, CD31, F8, CK, MBP, indicating that the tumor was benign. It showed no evidence of recurrence on the patient during 9 years follow-up.
