Prevalence of allergic rhinitis and survey analysis of health service needs and utilization in Qingdao area / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the need and utilization for health services in patients with allergic rhinitis in Qingdao area.</p><p><b>METHODS</b>An investigation was conducted by the method of combining multi-stage sampling and cluster sampling. SPSS 13.0 software was used to analyse the data.</p><p><b>RESULTS</b>Among Two thousand and four hundred questionnaires, two thousand and fifty-two questionnaires were available. The effective rate was 85.5%. The total two-week prevalence in male was 6.5%, while that in female was 6.2%. There was no significant difference between male and female (χ(2) = 0.103, P > 0.05). The total ratio of those who visited doctors was 1.7%. The ratio of those who visited doctors in the first two weeks was 26.7% (35/131). 49.0% of non-users of health service thought it was unnecessary to consult a doctor because of mild symptoms. In the investigation about the allergic rhinitis, 60.2% patients (1235/2052) confessed that they heard of allergic rhinitis, 30.0% patients (616/2052) thought of allergic rhinitis was common cold.</p><p><b>CONCLUSIONS</b>The number of patients treated for allergic rhinitis was less than its prevalence. The primary reason for low attendance was that the majority of patients with mild symptoms thought it was no need to see a doctor. In order to improve the residents' health services utilization, medical education for allergic rhinitis is necessary.</p>

Observation of neural electrophysiology and morphology in traumatic optic neuropathy in cat model / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To establish the animal model of traumatic optic neuropathy similar to clinical feature by injuring the optic nerve of the pipeline through the ethmoid and sphenoid sinus. The electrophysiology and morphology were observed.</p><p><b>METHODS</b>The optic nerve in 2 cats was anatomically observed. Thirty healthy adult cats were divided into 1 h, 1 d, 3 d, 1 w, 2 w, 4 w injury groups. The right eye was selected as the experiment eye, and the left as the control. The optic canals were damaged by the injury instrument. The changes of optic nerve were observed using light and electron microscope. The pattern reversal visual evoked potential (PR-VEP) was used to determine the succeed model and pupil was monitored. PR-VEP and neural tissue morphology were examined at intervals of 1 h, 1 d, 3 d, 1 w, 2 w, 4 w after trauma.</p><p><b>RESULTS</b>Eight cats had Marcus-Gunn's pupil, and 22 cats did not have after injury. Neural tissue was physaliphorous degeneration in light microscope. The neural fibers swelled gradually and fibers physaliphorous degeneration in the first day after damage. At the seventh day, the bubble enlarged to be a big flat. After two weeks, the big flat bubble came out to be a bigger bubble. Under the electronic microscope, axons were physaliphorous degeneration, crack emerged between axon membrane and myelin sheath and myelin sheath were loose in the first day. At the third day, axon swelled, physaliphorous degeneration rose and myelin sheath were loose obviously. At the seventh day, axon and myelin sheath appeared loop in half cycle and bubble-like broke up. A lot of pieces came out and axon became physaliphorous and uniform. Microtubule and microfilament disappeared. After two weeks, myelin sheath became onion-like. On fourth week, myelin sheaths enlarged and squeezed to center. Axoplasm disappeared and neural tissues collapsed.</p><p><b>CONCLUSIONS</b>This animal model was similar to clinical optic nerve decompression through ethmoid and sphenoid sinus. The change of PR-VEP and neuromorphology were distinct before and after trauma. The pathological changes of optic nerve catching vibrated injury are mainly degeneration, so earlier decompression of optic nerve may improve the visual function.</p>

Endoscopic optic nerve decompression in traumatic optic neuropathy: analysis of 72 cases / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To review the effects of optic nerve decompression by endoscopic technique in traumatic optic neuropathy.</p><p><b>METHODS</b>Seventy-two patients (73 eyes) with traumatic optic neuropathy which were treated with large dose of glucocorticoid but inefficacious were undergone endoscopic optic nerve decompression. The days from injury to surgery were 1-57 d. Among that, < or = 3 d 15 cases, 4-7 d 37 cases, 8-10 d 9 cases, 11-15 d 5 cases, 16-30 d 5 cases, >30 d 1 cases. The vision of pro-operation: with light perception or higher grades 18 eyes; with no light perception 55 eyes.</p><p><b>RESULTS</b>All patients were followed up for more than 3 months. Fourty-six of 73 eyes had improvements in visual acuity, the total effective rate was 63.01%. Thirty-one of 55 eyes with no light perception had raises in visual acuity (56.36%). Fifteen of 18 eyes with light perception or higher grades had improvements (83.33%). No complication had happened.</p><p><b>CONCLUSIONS</b>Endoscopic optic nerve decompression is an appropriate technique for patients with traumatic optic neuropathy. Even though the patient has injured in longer time and high-dose steroid treatment has failed, optic nerve decompression may improve visual acuity.</p>
