HPV 16/18-DNA was found in 24 cases of laryngeal papillomas (68. 8 %). Overexpression of P53 protein was detected in 19 cases (54. 3 % ). Both HPV16/18-DNA and overexpression of P53 protein were demon-strated in 12 cases of laryngeal papillomas (34. 3 % ). Our results suggest that HPV16/l8 infection and P53 gene mutation are associated with pathogenesis of la-ryngeal papillomas. The relation between HPV infection and P53 mutation in tis-sues of laryngeal papillomas remains to be clarified.展开更多

Study Design: This is a retrospective study. Setting: Tertiary referral centre. Subjects and Methods: All the patients diagnosed with laryngeal papillomatosis between January 2013 to December 2016 were included in this study. Preoperative assessment was done with rigid and flexible laryngoscopy. PRAAT software was used for voice analysis. All patients underwent coblation assisted microlaryngeal surgery. Post operatively patients were followed up at 1 week, 15 days, 1 month, 3 months and 6 months with rigid laryngoscopy. Voice analysis was repeated after 3 months to assess the improvement in voice. Results: Coblation was found to be effective in treating laryngeal papillomatosis. In our series of seven patients, three patients underwent repeat procedure with coblation for recurrence. But longterm follow up these patients did not reveal any recurrence of laryngeal papillomatosis. Voice analysis revealed a significant improvement in measures of perturbation and maximum phonation time. Conclusion: Coblation is a promising alternative to the conventional methods for the treatment of laryngeal papillomas as it can achieve satisfactory disease clearance with good voice quality.展开更多

Method: we examined representative numbers of specimens from laryngeal cancer with highly sensitive PCR technique for the presence of HPV L1 and high-risk types HPV16 E6, HPV18 E6 and EBV LMP1. Results: Using PCR detection, 7.3% samples were HPV L1 positive, 52.03% were HPV16 E6 positive, 30.89% were HPV18 E6 positive and 9.13% were EBV LMP1 positive. The low incidence of HPV L1 and high incidence of HPV-16 E6 and HPV18 E6 genes suggest that HPV might be integrated into tumor cells. Our results support a role of HPV-16 and HPV-18 infection in the pathogenesis of laryngeal carcinoma in China. Conclusion: Integration of E6 into host genome and stable expression of these genes may be associated with the carcinogenesis of laryngeal carcinoma. HPV-16 and HPV-18 may synergistically function on the pathogenesis of laryngeal carcinoma. Our results suggest an association of laryngeal carcinogenesis and infection with the high-risk HPV types 16, HPV 18 and EBV.展开更多

Dysphonia, dyspnea and dysphagia are evocative signs. Diagnosis is histological and squamous cell carcinoma is the most common type. The objective of our study was to discuss epidemiological and anatomo-pathological characteristics of laryngeal cancers diagnosed in different pathological anatomy and cytology (ACP) laboratories of Dakar hospitals. Material and method: This was a retrospective study spanning from January 2013 to December 2018 at the pathological anatomy laboratories of Fann, Aristide Le Dantec and Idrissa Pouye hospitals. All patients with laryngeal cancer confirmed at histology were included. Data collection was based on clinical records of the patients and archives of histological reports of the pathological laboratories. Data analysis was performed under the Excel software. Results: We collected 215 cases of laryngeal cancer. The average age was 58.01 years with extremes of 07 and 94 years. The male sex was predominant with 183 patients (85.12%) against 32 women (14.88%). The most noted risk factor was tobacco which affected 14 patients, or 60.87%. Three patients (13.04%) did not present any alcohol-smoking impregnation. Clinically, dysphonia was noted in 22 patients (26.51%). It was associated with dyspnea in 0.48% of cases and dysphagia in 3.61%. Laryngoscopy was performed in 62 patients or 28.83% of cases, nasofibroscopy in 6.45% of cases. Cord arythenoid fixity was noted in two patients (3.23%) and hypo-mobility in 1 patient (1.61%). The most frequent local extension was involvement of the piriform sinus with 11.29% of cases. Palpable lymphadenopathy reported in 17 patients (20.48%). Pathological examination was performed in all patients after post endoscopic biopsy in 92 patients (42.79%), and after obtaining the operative specimen in 123 cases (57.21%). The three floors affected 76 patients (35.35%). The ulcerative budding aspect most noted concerned 108 patients (60.97%). Histologically, it was a squamous cell carcinoma in 205 patients (95.34%). The most site invaded by the tumor was cricoid cartilage.T4 type was most found (45 patients or 40.90%) followed by the T3 type with 34.55%. There was no lymphadenopathy invasion (Type N0) in 74 patients (67.27%), capsular rupture was reported in five patients (6.77%), no evaluable metastasis in 110 patients (97.27%), and stage IVA predominated in 66 patients (60%). Conclusion: laryngeal cancer is a reality in our contexts, however, its incidence is poorly understood in Senegal. The main risk factors remain tobacco and alcohol. Histology confirms the diagnosis. Its management is multidisciplinary and must be early.展开更多

At present, the treatment of laryngeal cancer is mainly surgical treatment or postoperative radiotherapy. The surgery is delicate, complex, time-consuming and traumatic. Postoperative patients are prone to dysphagia, leading to an increase in the incidence of malnutrition. Malnutrition can cause a series of negative effects, including weight loss, increased incidence of infection, reduced tolerance of anti-tumor treatment, and extended length of hospital stay. Therefore, how to effectively improve the nutritional status of laryngeal cancer patients through nursing intervention has become an important topic of nursing research. Objective: Investigate the effect of individualized nutrition intervention care combined with swallowing training on postoperative nutritional status in patients with laryngeal cancer. Methods: A total of 120 consecutive patients who underwent laryngeal surgery at our hospital for the first time between May 2018 and May 2021 were selected for the study and equally divided into the control group and the study group by the random number table method, with 60 patients in each group. Patients in the control group were given swallowing function training and health counseling, and the study group adopted individualized nutrition intervention care based on the control group. The nutritional status, swallowing function, and quality of life (QOL) of the patients were assessed using the Patient-generated Subjective Global Assessment (PG-SGA), MD Anderson Dysphagia Inventory (MDADI), and Quality of Life Questionnaire-Core30 (QLQ-C30) before the intervention and three months after the intervention. Results: Before the intervention, the scores of MDADI, PG-SGA, and QLQ-C30 were not significantly different between the two groups (P > 0.05), and three months after the intervention, the scores of MDADI and QLQ-C30 increased and the score of PG-SGA decreased in the study group, with significant differences (P 0.05). At three months after the intervention, patients in the study group had higher scores on MDADI, QLQ-C30 and lower scores on PG-SGA than the control group, with significant differences (P Conclusion: Combining individualized nutrition intervention care with swallowing training improves the postoperative nutritional status, swallowing function, and QOL of patients with laryngeal cancer.展开更多

Its clinical presentation is nonspecific, often pointing to cancer. We report the case of a 77-year-old woman, with no reported pathological history. She also has no alcohol or tobacco intoxication, who presented with chronic dysphonia evolving for 2 months, associated with an altered general condition. The examination of the larynx by direct laryngoscopy and anatomical pathology study of the biopsies led to the diagnosis of laryngeal tuberculosis. A search for secondary sites revealed a concomitant pulmonary infection. The evolution was favorable under standard anti-tuberculosis treatment, with complete voice recovery and improved performance status. Laryngeal tuberculosis should be suspected in patients living in endemic areas and suffering from chronic dysphonia, even if they are not alcoholics or smokers.展开更多
