Scales of degree of facial paralysis: analysis of agreement

IntroductionIt has become common to use scales to measure the degree of involvement of facial paralysis in phonoaudiological clinics.ObjectiveTo analyze the inter- and intra-rater agreement of the scales of degree of facial paralysis and to elicit point of view of the appraisers regarding their use.MethodsCross-sectional observational clinical study of the Chevalier and House & Brackmann scales performed by five speech therapists with clinical experience, who analyzed the facial expression of 30 adult subjects with impaired facial movements two times, with a one week interval between evaluations. The kappa analysis was employed.ResultsThere was excellent inter-rater agreement for both scales (kappa > 0.80), and on the Chevalier scale a substantial intra-rater agreement in the first assessment (kappa = 0.792) and an excellent agreement in the second assessment (kappa = 0.928). The House & Brackmann scale showed excellent agreement at both assessments (kappa = 0.850 and 0.857). As for the appraisers’ point of view, one appraiser thought prior training is necessary for the Chevalier scale and, four appraisers felt that training is important for the House & Brackmann scale.ConclusionBoth scales have good inter- and intra-rater agreement and most of the appraisers agree on the ease and relevance of the application of these scales.

Effects of time of contact and concentration of caustic agent on generation of injuries

OBJECTIVES: Solid caustic soda (CS) ingestion levels continue high in Brazil. The aggressiveness of a caustic agent depends, among other factors, on its concentration and time of contact with mucosa. However, the interdependence of these factors in the production of caustic lesion in the esophageal mucosa is not known, especially regarding CS as the strongest corrosive agent. We analyze the effects of concentration and time of contact on the aggressiveness of CS to the esophagus of live animals. STUDY DESIGN/METHODS: One milliliter of CS at concentrations between 1.83% and 73.33% was applied to rats. The solution was kept in contact with the mucosa for 10 to 120 minutes. Internal and external organ aspects were analyzed and the epithelium, submucosa, muscle layer, and adventitia were analyzed microscopically RESULTS: Epithelial necrosis was observed at all concentrations. Among the necrotic layers, the submucosa was observed starting at the 7.33% concentration, and the muscular layer and adventitia were observed at 14.66% concentration. Damage to the pulmonary parenchyma and trachea occurred at 33.66% after 10 minutes, and perforation of the esophagus was observed only after 120 minutes. After 10 minutes, important corrosive lesions installed in the esophageal layers, expanding in depth and superficial extension. The use of heparin had no effect on the production of lesions. CONCLUSIONS: Ten minutes were sufficient to provoke necrosis, and longer contact increased the area of necrosis. Solution concentration levels were more important in damage production: 1.83% was sufficient for epithelial necrosis, 7.33% caused submucosal necrosis, and 14.66% muscle and adventitia necrosis; 33.66% solutions caused lung and trachea damage after 10 minutes and esophageal perforation after 120 minutes.

A national audit of sinus surgery. Results of the Royal College of Surgeons of England comparative audit of ENT surgery

The results of a national audit of sinus surgery are presented. Forty-six consultant ENT surgeons reported on over 2500 sinus procedures. There has been an exponential rise in the number of surgeons in England and Wales performing functional endoscopic sinus surgery (FESS) in recent years. Sixty-five per cent of surgeons in our study used the FESS technique and 81% had formal or other training. Outpatient sinus endoscopy and CT scans have become more routine pre-operative investigations, whilst the use of plain films has waned. There was a wide variation in the numbers of FESS procedures performed by individual surgeons in the 6-month period (between 5 and 85). The overall complication rate was 0.75% for conventional surgery and 1.41% for functional surgery but no major complications were recorded. The primary symptom of blockage was most successfully treated by both conventional and functional surgery (70% and 84% asymptomatic or improved at 6 months). Pain was relieved in 75% of functional procedures and 47% of conventional procedures and discharge relieved in 76% of FESS procedures and 47% of conventional procedures.     

磷霉素在减轻卡那霉素耳中毒过程中的作用

本文采用磷霉素笔卡那霉素联合应用，经扫描电镜、透射电镜、耳蜗铺片和组织化学反应观察，了解磷霉素减轻卡那霉素耳毒性的机制以及卡那霉素所致耳毒性的发展过程。通过实验可以看到磷霉素有保护溶酶体膜的作用，所以能减轻卡那霉素的耳毒性，但由于它不能直接对抗AmAn耳毒性作用机制，因而不能完全预防其耳毒性。     

慢性鼻窦炎病原学变迁的研究

目的:了解慢性鼻窦炎病原学分布的变迁。方法:术中收集2010年全年111例(实验组)上颌窦或筛窦脓性分泌物,分别进行需氧菌和真菌培养,同时以30例健康受试者作为对照组,其培养结果与2005年的各种数据比较,分析病原微生物的分布变化。结果:实验组共培养出15种病原微生物,主要为肺炎克雷伯菌、甲型链球菌、鲍曼不动杆菌、表皮葡萄球菌、铜绿假单胞菌、白色念珠菌等;需氧菌和真菌培养阳性率为81.8%,其中革兰阳性菌37.8%,革兰阴性菌54.4%,各种真菌7.8%;对照组检测出表皮葡萄球菌、流感嗜血杆菌、甲型链球菌、卡他布兰汉菌和金黄色葡萄球菌5种细菌,与实验组比较差异有统计学意义(χ2=0.009,P<0.01);与2005年数据(革兰阳性菌56.3%,革兰阴性菌43.7%,真菌阳性率1.4%)比较,其分布特征有明显差异。结论:细菌感染是慢性鼻窦炎的重要原因之一;细菌分布结构从原来的革兰阳性菌变成现在的以革兰阴性菌为主,真菌感染也不容忽视。应用抗生素治疗宜先进行细菌培养与药敏试验。     

扁桃体术后出血的原因分析

目的：探讨扁桃体术后出血的常见原因,并提出相应的预防措施。方法：选取扁桃体切除术患者1192例,根据其是否发生术后出血分为两组,对两组患者的基本资料和治疗情况进行统计学分析。结果：扁桃体术后出血者中成年、男性患者,合并高血压、肝脏疾病,术前长期服用阿司匹林,术前长期使用肾上腺皮质激素,局部麻醉,术中采取纱球压迫止血,术后剧烈咳嗽,不合理进食,以及围手术期存在焦虑情绪的患者所占比例明显高于未发生出血者,两组比较差异有统计学意义（P〈0．05）。而患者是否合并糖尿病对其术后出血影响不大（P〉0．05）。经Logistic回归分析,焦虑,合并高血压、肝脏疾病,使用纱球压迫止血,术后剧烈咳嗽以及不合理饮食都是患者发生扁桃体出血的原因（P〈0．05）。结论：扁桃体术后出血与多方面的因素密切相关,在临床工作中应给予针对性的预防。     

Effect of the loss of auditory feedback on segmental parameters of vowels of postlingually deafened speakers

Objective: The most obvious and best documented changes in speech of postlingually deafened speakers are the rate, fundamental frequency, and volume (energy). These changes are due to the lack of auditory feedback. But auditory feedback affects not only the suprasegmental parameters of speech. The aim of this study was to determine the change at the segmental level of speech in terms of vowel formants. Methods: Twenty-three postlingually deafened and 18 normally hearing speakers were recorded reading a German text. The frequencies of the first and second formants and the vowel spaces of selected vowels in word-in-context condition were compared. Results: All first formant frequencies (F1) of the postlingually deafened speakers were significantly different from those of the normally hearing people. The values of F1 were higher for the vowels /e/ (418±61 Hz compared with 359±52 Hz, P=0.006) and /o/ (459±58 compared with 390±45 Hz, P=0.0003) and lower for /a/ (765±115 Hz compared with 851±146 Hz, P=0.038). The second formant frequency (F2) only showed a significant increase for the vowel/e/(2016±347 Hz compared with 2279±250 Hz, P=0.012). The postlingually deafened people were divided into two subgroups according to duration of deafness (shorter/longer than 10 years of deafness). There was no significant difference in formant changes between the two groups. Conclusion: Our report demonstrated an effect of auditory feedback also on segmental features of speech of postlingually deafened people.

目的 探讨鼻腔鼻窦内翻性乳头状瘤起源的CT影像学特点。 方法 回顾性分析47例经鼻内镜手术及术后病理组织学确诊的鼻腔鼻窦内翻性乳头状瘤患者的CT影像学资料。对肿瘤病变在CT上的骨质变化进行分析,并与术中发现的肿瘤起源根蒂部位进行对比,分析CT影像中骨质改变与肿瘤起源之间的关系。 结果 47例患者中,39例有骨质增生影像表现,其中37例骨质增生部位与肿瘤起源的根蒂部位一致,一致性达78.7%,提示可根据骨质增生部位推测肿瘤起源位置。 结论 CT影像中的骨质增生与鼻腔鼻窦内翻性乳头状瘤的根蒂起源部位有较高的一致性,有助于术前评估肿瘤起源和指导术前制定合理的手术方案。     

Considerations of isolated destruction of the short process of the incus in a case of cholesteatoma

Cholesteatoma occurs frequently with the destruction of the ossicles. The most commonly eroded ossicle has been reported to be the incus. Many studies report destruction of the long process and body of the incus. However, isolated erosion of the short process of the incus is an unusual finding. We present such a case with a slight conductive hearing loss that remained unchanged at 2 1/2 years postoperatively. The short process of the incus may contribute to hearing up to 10–15 dB. It is also possible that it plays a role in epitympanic aeration by supplying an attachment surface to the incudal folds.     

咽喉反流与发声障碍的相关性研究

目的:探讨咽喉反流的嗓音学特征及其对患者生活质量的影响,分析主客观评估方法的相关性。方法:对196例可疑有咽喉反流的患者行一般情况调查、电子鼻咽喉镜检查、反流症状指数量表(RSI)和反流检查计分量表(RFS)评估,将其中RSI评分>13分、RFS评分>7分定为阳性。将2个量表评分均为阳性的100例患者作为研究对象,进一步进行嗓音障碍指数量表(VHI)评估、嗓音声学分析及电声门图检查,并与健康对照组比较。结果:男女基频均比健康对照组降低,基频微扰、振幅微扰及标准化噪声能量增高,接触率降低,最大发声时间缩短,与健康对照组比较,差异均有统计学意义(均P<0.01)。VHI量表评估生理P评分最高,其次为功能F评分,情感E评分最低。咽喉反流患者的RSI与VHI有一定相关性(P<0.05),而RFS与RSI、VHI无明显相关性(P>0.05)。咽喉反流患者的嗓音障碍指数评估示生理、功能和情感之间明显相关。结论:嗓音声学分析及电声门图检测从客观上提示咽喉反流相关的嗓音障碍疾病严重影响了喉的发声功能,使基频下降、声带振动不稳定、声门闭合不良及声门接触时间缩短。主客观评估方法的相关性结果提示具有明显咽喉反流症状的患者并不一定具有明显的咽喉反流体征。
