Patients with BPVC were tested with pure tone audiometry, high stimulus rate auditory brainstem response test (ABR), transcranial Doppler sonography (TCD), bithermal caloric test, and VEMP. The results of the hearing and vestibular function test were compared and analyzed.
Results: There were 56 patients with BPVC, including 32 men, 24 women, aged 3-12 years old, with an average of 6.5 years. Among 56 cases of BPVC patients, the results of pure tone audiometry were all normal. High stimulus rate ABR was abnormal in 66.1% (37/56) of cases. TCD showed 57.1% abnormality in 56
cases, including faster flow rate in 28 cases and slower flow rate in 4 cases. High NCT-501 cell line stimulus rate ABR and TCD were both abnormal in 48.2% (27/56) of cases. Bithermal caloric test was abnormal in 14.3% (8/56) of cases. VEMP showed 32.1% abnormality, including amplitude abnormality in 16 cases and latency abnormality in 2 cases. The abnormal
rate of VEMP was much higher than that of caloric test.
Conclusion: Vascular mechanisms might be involved in the pathogenesis of BPVC and there is strong evidence for close relationship between BPVC and migraine. High stimulus rate ABR is helpful in the diagnosis of BPVC. The inferior vestibular pathway is much more impaired than the superior vestibular pathway in BPVC. (C) 2011 Elsevier Ireland Ltd.

“Iatrogenic https://www.selleckchem.com/products/tariquidar.html subclavian artery puncture following central venous catheterization is a rare but potentially fatal complication. There are very few reports in AZD2171 nmr the literature on this condition. We propose the use of video-assisted thoracic surgery (VATS) in the management of these injuries.
The technique of VATS to manage subclavian artery injury was described. We presented the first reported case of successful repair of subclavian
artery injury using VATS.
Using a two-incisional approach for VATS, the haemothorax was rapidly evacuated and the subclavian artery injury was successfully repaired using pledgetted sutures under direct thoracoscopic visualization. The patient had an uneventful postoperative recovery.
VATS can be successfully applied to repair subclavian artery injury. The advantages include rapid intrathoracic access, excellent thoracoscopic visualization of the thoracic inlet, and avoidance of the morbidity associated with open thoracotomy.”
“In this article, the structural properties of Cynomorium songaricum Rupr. polysaccharide (CSP) after selenylation were investigated. The crude polysaccharide was obtained from C. songaricum Rupr. by water extraction followed by ethanol precipitation and freeze vacuum drying. Then selenylation of CSP has been accomplished by employing sodium selenite to modify the polysaccharide under the catalysis of nitric acid-barium chloride.
