The Correlation between Benign Laryngeal Mucosal Disease and Metabolic Syndrome

BACKGROUND AND OBJECTIVES: The aim of this study is verify the correlation between benign laryngeal mucosal disease and metabolic syndrome. MATERIALS AND METHOD: Data for patients diagnosed with benign laryngeal mucosal disease and metabolic syndrome from 2006 to 2015 were selected for analysis from the National Health Insurance Service database. RESULTS: The prevalence of Metabolic syndrome was 2,179,785 out of 6,437,051 patients (33.86%). The prevalence of benign laryngeal mucosal disease was 516,594 out of 6,437,051 patients (8.03%). Metabolic syndrome was a risk factor for benign laryngeal mucosal disease [hazard ratio: 0.99, 95% confidence interval: 0.984–0.997] after adjusting for age and other variables including age, gender, smoking status, alcohol intake, exercise, body mass index, and diabetes. The number of metabolic syndrome components was also risk factor. CONCLUSION: Metabolic syndrome was related to the incidence of benign laryngeal mucosal disease. However this correlation did not seem to be high.

Influence of TNF-α on the immunomodulatory property of laryngeal mucosa mesenchymal stromal cells′ / 中华耳鼻咽喉头颈外科杂志

Objective@#To investigate the effect of tumor necrosis factor-alpha(TNF-α)on the immunoregulatory capacity of laryngeal mucosal mesenchymal stromal cells (LM-MSCs) and its potential molecular mechanism, and provide a theoretical basis for the study of chronic laryngitis.@*Methods@#LM-MSCs were separated from epiglottal mucosa. The LM-MSCs cells were directly co-cultured with T cells in vitro to detect the immunomodulatory property of LM-MSCs. After long-term stimulation with inflammatory factors TNF-α in vitro, the differences were compared in the immunomodulatory ability of LM-MSCs between normal LM-MSCs and TNF-α stimulated LM-MSCs. The expression of general control non-repressed protein5(GCN5), FAS, FASL in normal LM-MSCs and TNF-α stimulated LM-MSCs was detected by Western blot and quantitative real-time RT-PCR(RT-qPCR).@*Results@#After chronic stimulation of TNF-α, the RNA relative expression of GCN5 was 0.31±0.03 (3 days) and 0.53±0.06 (7 days) compared with control group, showing significant difference (F=13.45, P<0.05). The percentage of LM-MSC-induced T cell apoptosis was 6.27%±0.81% (3 days) and 4.99%±0.52% (7 days) in chronic stimulation group compared with control group 10.02%±1.02%. There is a significant difference among these groups (F=11.13, P<0.05). Moreover, the ability of LM-MSCs to induce T cell apoptosis is regulated by GCN5.@*Conclusion@#With the chronic stimulation of TNF-α, the expression of GCN5 in LM-MSCs is decreased, thus impairing its immunoregulatory capacity.

Surgical approach to the thyroarytenoid branch of the inferior laryngeal nerve through the thyroid cartilage

ABSTRACT PURPOSE: To describe the anatomical course of the intralaryngeal portion of the inferior laryngeal nerve (ILN) and to standardize the surgical access to its thyroarytenoid branch (TAb) through the thyroid cartilage. METHODS: Under surgical microscopy, 33 adult human excised larynges were dissected, to expose the intralaryngeal portion of ILN. The point of entry of TAb, ILN's terminal branch, in the thyroarytenoid (TA) muscle was determined and correlated with thyroid cartilage dimensions. RESULTS: After entering the larynx, the ILN consistently traveled between the thyroid cartilage and the lateral cricoarytenoid muscle in an anterior and slightly cranial course. The distance from the point of entry of the TAb in the TA muscle to the midline (TAb-H) and to the inferior border (TAb-V) of the thyroid cartilage differed according to gender. In females, mean distances of TAb-H and TAb-V were 20.5mm and 5.2mm and in males, 22.3mm and 5.9mm, respectively. CONCLUSION: The intralaryngeal course of the inferior laryngeal nerve presents low variability and measures from landmarks in the thyroid cartilage help to estimate the point of entry of thyroarytenoid branch in thyroarytenoid muscle.

Level of anxiety versus self-care in the preoperative and postoperative periods of total laryngectomy patients / Nível de ansiedade versus autocuidado no pré-operatório e pós-operatório do paciente laringectomizado total / Nivel de ansiedad versus autocuidados en el preoperatorio y postoperatorio del paciente con laringectomía total

Abstract Objective: estimate the prevalence of anxiety in laryngectomy patients in the pre and postoperative periods and its relation with the self-care level. Method: observational research of 40 patients with stage IV laryngeal cancer. Three observations took place: in the preoperative phase, at seven and at 14 days after the surgery; between June 2010 and December 2012. Two self-care levels were defined: self-sufficient and needing help for activities of daily living and treatment-related activities. To assess the anxiety levels, Zigmond's hospital anxiety scale (1983) was used. Results: in the preoperative and postoperative phases, the patients presented high levels of anxiety. Concerning self-care, on average, self-sufficient patients presented lower levels of anxiety than patients who needed help to accomplish activities of daily living and activities deriving from the surgery, without significant differences. Conclusion: anxiety is present at all times in laryngectomy patients and the reduction of the self-care deficit seems to decrease it, without putting a permanent end to it.

Resumo Objetivo: estimar a prevalência de ansiedade do paciente laringectomizado no pré-operatório e pós-operatório e sua relação com o nível de autocuidado. Método: pesquisa observacional de 40 pacientes com câncer da laringe estágio IV. Foram realizadas 3 observações: no pré-operatório, a 7 e 14 dias pós-operatório, no período de junho de 2010 a dezembro de 2012. Dois níveis de autocuidado foram definidos: autossuficientes e precisar ajuda para as atividades da vida diária e relacionadas ao tratamento. Para avaliar a ansiedade, foi utilizada a escala de ansiedade hospitalar de Zigmond (1983). Resultados: no pré-operatório e pós-operatório, os pacientes apresentaram níveis elevados de ansiedade. Com relação ao autocuidado, os pacientes autossuficientes apresentaram na média níveis inferiores de ansiedades que os pacientes que precisavam de ajuda para realizar as atividades da vida diária y as derivadas da cirurgia, sem chegar a ser significativas estas diferenças. Conclusão: a ansiedade está presente a todo momento no paciente laringectomizado e a diminuição do déficit de autocuidados parece diminuí-la sem acabar definitivamente com ela.

Significance of S-100 and CD83+DC Expression in Laryngeal Mucosa Lesions / 天津医药

Objective To investigate the infiltration of dendritic cell (DC) in Vocal cord polyp, laryngeal leukopla-kia and glottic squamous cell carcinoma,and to observe laryngeal mucosal lesions of the state of the immune microenviron-ment, and to research significance of DC on the development of glottic squamous cell carcinoma. Methods The infiltration of S-100+and CD83+DC in 20 cases of Vocal cord polyp, 47 cases of laryngeal leukoplakia, 45 cases of glottic squamous cell carcinoma tumor and 20 cases of laryngeal normal mucosa were examined using immunohistochemistry. Results The num-ber of S-100+and CD83+DC were significantly higher in glottic squamous cell carcinoma, laryngeal leukoplakia and vocal cord polyp than that in laryngeal normal mucosa (P<0.05). The number of S-100+and CD83+DC were higher in laryngeal leukoplakia than that in glottic squamous cell carcinoma (P<0.05). The number of S-100+and CD83+DC in mild dysplasia and moderate dysplasia were less than that in severe atypical hyperplasia (P<0.01). In glottic squamous cell carcinoma, S-100+ and CD83+DC with poor-differentiated was significantly less than that with well-differentiated (P < 0.01). Conclu-sion Changes in the number of dendritic cell was found in vocal cord polyp, laryngeal leukoplakia and glottic squamous cell carcinoma, which indicated that there were an abnormal immune status. Changing of dendritic cell in laryngeal mucosa plays an important role in laryngeal cancer development.

Refluxo laringofaríngeo e bulimia nervosa: alterações vocais e larínegas / Laryngopharyngeal reflux and bulimia nervosa: laryngeal and voice disorders

TEMA: Características da bulimia nervosa (BN) e do Refluxo Laringofaríngeo (RLF) e alterações vocais e laríngeas que podem decorrer da exposição da laringe ao ácido gástrico. OBJETIVO: Descrever, por meio de revisão de literatura, as características do RLF e da BN, relacionando-os com as alterações vocais e laríngeas que podem se originar da exposição da laringe ao ácido gástrico que ocorre em ambas as condições. CONCLUSÃO: A BN se caracteriza por um transtorno alimentar de causa principalmente psicológica em que ocorre ingestão compulsiva de grande quantidade de alimentos, seguida de episódios de vômitos auto-induzidos com a finalidade de evitar o ganho de peso. O RLF consiste em uma variação clínica da DRGE, na qual o fluxo retrógrado do alimento e do ácido gástrico entra em contato com a laringe e suas estruturas. Em comum, a BN e o RLF apresentam este mecanismo de regurgitação que pode atingir a laringe. Dentre os sinais e sintomas laríngeos e vocais decorrentes da regurgitação do ácido gástrico sobre a laringe estão: globus faríngeo, disfonia, rouquidão, tosse seca, disfagia, halitose, lesões inflamatórias nas pregas vocais, laringite, amigdalite, edema e eritema glótico posterior e ou de aritenóides, da região retrocricóidea e interaritenóidea, estenose subglótica, irregularidades na mucosa das pregas vocais, hipertrofia de mucosa laríngea, leucoplasia, carcinoma, laringoespasmos, granulomas, úlcera de contato, nódulos vocais, pólipos vocais, edema difuso, granuloma, fixação uni ou bilateral de aritenóides, edema de Reinke, laringomalácia, estridor, e odinofagia.

BACKGROUND: Characteristics of bulimia nervosa (BN) and laryngopharyngeal reflux (LPR) and laryngeal and voice disorders that can arise from exposure to gastric acid of the larynx. PURPOSE: To describe, through literature review, the characteristics of LPR and the BN, linking them with laryngeal and voice disorders that can stem from exposure to gastric acid of the larynx, occurring in both conditions. CONCLUSION: BN is characterized by an eating disorder, where there is a mainly psychological compulsive ingestion of large quantities of food, followed by episodes of self-induced vomiting in order to prevent weight gain. LPR consists of a clinical variation of gastro esophageal reflux disease (GERD), in which the retrograde flow of food and stomach acid comes into contact with the larynx and its structures. In common, BN and LPR have this mechanism of regurgitation that may reach the larynx. The signs and symptoms arising from the vocal and laryngeal regurgitation of gastric acid on the larynx are: globus pharynx, dysphonia, hoarseness, dry cough, dysphagia, halitosis, inflammatory lesions on the vocal cords, laryngitis, tonsillitis, swelling and redness and / or posterior glottis of the arytenoids, and the retrocricoid and interarytenoid region, subglottic stenosis, irregularities in the vocal folds mucosa, hypertrophy of the laryngeal mucosa, leukoplakia, carcinoma, laryngospasm, granulomas, contact ulcer, vocal nodules, vocal polyps, diffuse edema, unilateral or fixing bilateral arytenoids, edema, laryngomalacia, stridor and odynophagia.

Relationship between external appearance of laryngeal carcinoma and submucosal infiltrating extent / 中国耳鼻咽喉头颈外科

OBJECTIVE To observe the submucosal infiltrating extent of laryngeal carcinoma tissue by different location,different T staging and external appearance and to analyze the impact of laryngeal carcinoma submucosal infiltrating extent on surgical margin.METHODS Forty-three laryngeal en bloc specimens coming from 43 cases with laryngeal carcinoma were vertically cut-down along tumor long axis,and were slivered into sections by which laryngeal carcinoma submucosal infiltrating distance was measured under microscope.Laryngeal carcinoma latent submucosal infiltrating extent was compared among different location,different T staging and external appearance.RESULTS Basing on tumor external appearance and infiltrating extent,laryngeal carcinoma was classified into three types:exogenic type,ulcerating infiltrating type and mixed infiltrating type.Of 43 specimens,the three types were 10,8 and 25 cases respectively.There was a significant difference in submucosal infiltrating extent between T1～T2 and T3～T4 laryngeal carcinoma.There was also significant difference in submucosal infiltrating extent between exogenic type and ulcerating infiltrating type or mixed infiltrating type.CONCLUSION The submucosal infiltrating extent of laryngeal carcinoma tissue plays an important role in the surgical margin. As laryngeal carcinoma T stage developing,tumor submucosal infiltrating extent is becoming more extensive.Laryngeal carcinoma submucosal infiltrating extents in ulcerating infiltrating and mixed infiltrating type are more extensive than that in exogenic type.The partial laryngectomy should be prudent to be performed in cases with local advanced ulcerating infiltrating and mixed infiltrating laryngeal carcinoma.
