title: Non-squamous cell carcinoma diseases of the larynx: clinical and imaging findings,

description: Abstract Introduction Squamous cell carcinoma is the most common laryngeal neoplasm and accounts for approximately 95% of all malignant neoplams of the larynx. However, various benign and malignant tumors and inflammatory diseases may affect the larynx. Objective The purpose of this study is to analyze the clinical and imaging findings of non-squamous cell neoplasms and inflammatory diseases of the larynx. Methods This retrospective study was conducted in 18 patients who were diagnosed with non-squamous cell carcinoma lesions of larynx at our institution between 2007-2017. Clinical symptoms, examination findings, imaging characteristics, histopathologic diagnosis and treatment modalities were analyzed. Results There were 9 malignant lesions (2 chondrosarcoma, 1 neuroendocrine tumor-atipical carcinoid, 1 Natural Killer/T-cell lymphoma, 1 diffuse large B-cell lymphoma, 3 plasmocytoma-multiple myeloma involvement, 1 adenocarcinoma metastasis), 3 benign neoplasms (chondroma, paraganglioma, lipoma), 2 tumor-like lesions (Brown tumor and inflammatory myofibroblastic tumor), 3 inflammatory lesions (Wegener granulomatosis, Behçet's disease and tuberculosis involvements), and 1 vascular malformation. The most common presenting symptom was hoarseness (66.6%). Paraganglioma was seen as hypervascular lesion on computed tomography and magnetic resonance imaging and showed intense tracer uptake on 68Gallium-DOTA-peptide PET/CT. Chondroid matrix calcifications were detected in chondroma and chondrosarcoma-grade 1. In patients with vascular malformation and lipoma, the typical imaging findings made it possible to diagnose. Conclusion Imaging studies may provide clues for diagnosis of non-squamous cell laryngeal lesions. Clinical and imaging findings and previous clinical history should be evaluated together in clinical management of laryngeal lesions.

title: Changes in substance P levels of inferior turbinate in patients with mucosal contact headache,

description: Abstract Introduction Mucosal contact headache is a referred pain that arises from contact between the nasal septum and the lateral nasal wall. Evidence supports the role of substance P in a contact headache such that release of substance P from sensory nerve endings causes inflammation and allergy. Objectives This study aimed to determine possible differences in substance P levels in inferior turbinate hypertrophy creating a contact headache. Methods 28 patients who had contact headaches (study group) and 16 volunteers with no complaints were included in the study. Substance P levels in the inferior turbinate tissue samples were quantified using a commercially available substance P EIA kit. Results In the study group average substance P levels were 2.65 ± 0.27 pg/mg tissue (range: 0.61–5.44) and in the control group it was 1.77 ± 0.27 pg/mg tissue (range: 0.11–4.35). The difference was statistically significant between the two groups (p = 0.0215). Average preoperative headache group visual analog scale scores was 5.93 ± 0.38 (2–9) and the turbinate volume was 6.56 ± 0.35 cm3 (3.50–10.30). The control group turbinate volume was 4.71 ± 0.39 cm3 (2.50–7.70). We found a correlation between the visual analog scale scores and substance P levels such that substance P levels were higher in visual analog scale scores above 5 (p = 0.001). Conclusion This study demonstrates the relationship between intranasal contact headaches and increased mucosal substance P levels. We also found that there is no correlation with substance P levels and volume of the inferior turbinate.

title: Trismus and oral health conditions during diagnosis of malignant oral neoplasms

description: Abstract Introduction: Trismus has been considered a late complication of cancer treatment. It can occur prior to treatment, mainly caused by tumor invasion or muscle spasms induced by the presence of the tumor. Objective: In this study, we evaluated the incidence of trismus and its effect on oral health in patients with malignant neoplasms of the oral cavity before performing the cancer treatment. Methods: This review was carried out via interviews, visual clinical inspection and objective measurement of maximal mouth opening in 35 consecutive patients. Trismus was defined as a maximal mouth opening &lt;35 mm. Results: Trismus was observed in 15 patients, with a total incidence of 42%. A high rate of tooth loss was recorded, and trismus association with tooth loss was statistically verified using the Chi-square and Fisher's exact tests, the t-student test and Mann-Whitney non-parametric test. All tests were performed at p &lt; 0.05. Conclusion: Edentulous patients are eight times more likely to have trismus compared to patients that are partially and fully dentate. Trismus was demonstrated to be correlated with tooth loss; however other oral health conditions were not shown to be a modifying factor.

title: Assessment of inflammatory markers in otosclerosis patients

description: Abstract Introduction Otosclerosis is an idiopathic disease characterized by new bone formation in foci of the human otic capsule. It is more common in Caucasian populations; affecting females twice as often as males. Its etiopathogenesis has not yet been fully elucidated. Objective The aim of this study was to investigate the relationship between otosclerosis and white blood cell and thrombocyte counts, mean platelet volume, neutrophil lymphocyte ratio, and the platelet lymphocyte ratio. Methods This retrospective case-control study was conducted in the outpatient clinic Mustafa Kemal University, in the department of otolaryngology, between 2015 and 2018. A total of 30 patients with an established diagnosis of otosclerosis were compared to a control group of 30 healthy subjects, matched for age, gender and body mass index. The white blood cell, thrombocyte, mean platelet volume, neutrophil lymphocyte ratio and platelet lymphocyte ratio values were calculated for all participants. Results There was no statistically significant difference between the groups with respect to age, gender, or body mass index, or for the mean neutrophil lymphocyte ratio, platelet lymphocyte ratio, white blood cell, or thrombocyte values (p &gt; 0.05). A statistically significant difference was determined between the groups for the mean platelet volume values. The mean platelet volume values were lower in the otosclerotic patients (p = 0.047). Conclusion These results show that neutrophil lymphocyte ratio, platelet lymphocyte ratio, white blood cell and thrombocytes should not be used to predict otosclerosis, but suggest that mean platelet volume may be a negative predictive marker.

title: Cortical auditory evoked potential in babies and children listeners

description: Abstract Introduction Cortical auditory evoked potentials have been increasingly used in research and audiological routines. However, there is a lack of studies with a large number of children who are stratified by age group. These would help clarify the variations in latency and amplitude of cortical auditory evoked potentials, and thus help establish reference values in children of different ages. Objective To identify the variation in latency and amplitude of the cortical auditory evoked potentials and to establish reference values for the pediatric population. Methods This was a cross-sectional study. Subjects were born at term and presented with no auditory complaints. A total of 105 children, of up to 6 years and eleven months old, who were divided into 7 age groups, named 1, 2, 3, 4, 5, 6 and 7, participated in the study. The tests were carried out using Biologic Navigator Pro. Initially, brainstem auditory evoked potential testing was performed in order to investigate the electrophysiological threshold of the subjects. Then, cortical auditory evoked potentials were elicited through oddball paradigm with tone burst differing in frequency, 750 Hz (frequent) and 1000 Hz (rare), and stimuli differing in speech: /ba/ (frequent) and /da/ (rare). In this study, descriptive and comparative analyzes of tonal and speech stimuli were performed for the age groups. Results Significant differences were observed when comparing cortical auditory evoked potentials with speech stimulus in the right ear for P2 amplitude, for P1 latency the left ear, for P2 amplitude of the left ear; and for P1 amplitude of the left ear when performed with tonal stimuli. Conclusion The obtained results can be considered as reference values of latency and amplitude of cortical auditory potentials in infants and children, and be used for monitoring their cortical auditory development.

title: Nasal lavage cytology and mucosal histopathological alterations in patients with rhinitis

description: Abstract Introduction The extent of epithelial lesion in allergic and non-allergic rhinitis and its association with inflammatory changes in nasal lavage has not been clarified. Objective To verify the association between the inflammatory cells in the nasal lavage, epithelial lesion extent and basement membrane thickness, in the nasal mucosa of patients with rhinitis; to determine the cutoff point of the percentage of eosinophils in the nasal lavage associated with the atopic patients. Methods Patients with rhinitis and indication for septoplasty and (or) turbinectomy for turbinate hypertrophy were selected, and were submitted to allergy skin tests, nasal lavage with measurement of albumin and interleukin-8 levels, total and differential counting of cells, and mucosal histopathological analysis to determine the extent of epithelial lesion, and degree of basement membrane thickening. Results Fifty-six patients with a median age of 24.5 years and a diagnosis of allergic rhinitis (n = 36) and non-allergic rhinitis (n = 20) were studied. In atopic subjects, allergy skin tests were positive for Dermatophagoides pteronyssinus in 35 (97.0%) and Lolium perenne in 18 (50.0%). Atopic subjects showed a higher clinical score index of rhinitis compared to non-atopic ones. The total count of cells, neutrophils, and levels of albumin and IL-8 were not different in the nasal lavage of atopic and non-atopic subjects. The cutoff point for eosinophil count in nasal fluid for the distinction between allergic rhinitis and non-allergic rhinitis was 4%. Some degree of epithelial lesion was more frequent in allergic rhinitis (94%) than in non-allergic rhinitis (65%) patients. In the presence of basement membrane thickness, as a marker of remodeling, there was no difference in the nasal lavage of patients with allergic rhinitis and non-allergic rhinitis. Conclusion In this series, 4% was the cutoff point for the number of eosinophils in the nasal lavage, for atopy differentiation. Upper airway remodeling accessed by basement membrane thickness showed similar inflammatory cell infiltrate in the nasal lavage, regardless of the presence of atopy.

title: Incomplete and late recovery of sudden olfactory dysfunction in COVID-19,

description: Abstract Introduction Sudden olfactory dysfunction is a new symptom related to COVID-19, with little data on its duration or recovery rate. Objective To characterize patients with sudden olfactory dysfunction during the COVID-19 pandemic, especially their recovery data. Methods An online survey was conducted by the Brazilian Society of Otorhinolaryngology and Cervico-Facial Surgery, and Brazilian Academy of Rhinology, including doctors who assessed sudden olfactory dysfunction patients starting after February 1st, 2020. Participants were posteriorly asked by e-mail to verify data on the recovery of sudden olfactory loss and test for COVID-19 at the end of the data collection period. Results 253 sudden olfactory dysfunction patients were included, of which 59.1% were females with median age of 36 years, with a median follow-up period of 31 days. 183 patients (72.3%) had been tested for COVID-19, and of those 145 (79.2%) tested positive. Patients that tested positive for COVID-19 more frequently showed non-specific inflammatory symptoms (89.7% vs. 73.7%; p = 0.02), a lower rate of total recovery of sudden olfactory dysfunction (52.6% vs. 70.3%; p = 0.05) and a longer duration to achieve total recovery (15 days vs. 10 days; p = 0.0006) than the ones who tested negative for COVID-19. Considering only positive-COVID-19 patients, individuals with sudden hyposmia completely recovered more often than the ones with sudden anosmia (68.4% vs. 50.0%; p = 0.04). Conclusion Positive-COVID-19 patients with sudden olfactory dysfunction showed lower total recovery rate and longer duration than negative-COVID-19 patients. Additionally, total recovery was seen more frequently in positive-COVID-19 patients with sudden hyposmia than the ones with sudden anosmia.

title: Auditory attention in individuals with tinnitus

description: Abstract Introduction Tinnitus is characterized by the presence of a sound in the absence of external sound stimulus. In individuals with normal audiometry, it may be associated with auditory attention difficulty, especially in those who report high tinnitus annoyance. Objective To investigate auditory attention ability in individuals with tinnitus complaint. Methods Cross-sectional analytical observational study. We evaluated 30 volunteers with normal hearing (up to 25 dBHL): 15 with tinnitus (test group) and 15 with no complaints (control group), aged between 18-40 years. The volunteers answered the tinnitus handicap inventory questionnaire and a visual analogue scale. Subsequently, a basic audiological evaluation (meatoscopy, tonal and vocal audiometry, and imittanciometry) and psychoacoustic measures of tinnitus (loudness and pitch) were performed. To evaluate auditory attention, the following tests were performed: auditory cognitive evoked potential (P300), central auditory processing tests (dichotic digits test and speech-in-noise test) and sustained auditory attention ability test. Results In the tinnitus handicap inventory, individuals with tinnitus had a mean score of 37.78 (±27.05), characterized as moderate degree. In the dichotic digits test (binaural separation), a difference was observed between the groups in both ears. Moreover, there was a difference in the speech-in-noise test in both ears (RE: p = 0.044; LE: p = 0.019), in P300 (p = 0.049) and in total sustained auditory attention ability test (p = 0.032). Also, there is a negative correlation between sustained auditory attention ability test, decrease in attentiveness and binaural integration (RE: p = 0.044; LE: p = 0.048). Conclusions Individuals with tinnitus had a poorer performance compared to the control group regarding auditory attention ability. Therefore, it is inferred that tinnitus is associated with poor performance in selective and sustained auditory attention in the assessed volunteers. These aspects should be considered for the management of patients with tinnitus.

title: The effects of music therapy in patients undergoing septorhinoplasty surgery under general anesthesia☆

description: Abstract Introduction Music has been used for several years as a relaxation method to reduce stress and anxiety. It is a painless, safe, inexpensive and practical nonpharmacologic therapeutic modality, widely used all over the world. Objectives We aimed to evaluate the effect of music therapy on intraoperative awareness, patient satisfaction, awakening pain and waking quality in patients undergoing elective septorhinoplasty under general anesthesia. Methods This randomized, controlled, prospective study was conducted with 120 patients undergoing septorhinoplasty within a 2 months period. The patients were randomly selected and divided into two groups: group music (music during surgery) and control group (without music during surgery). All patients underwent standard general anesthesia. Patients aged 18–70 years who would undergo a planned surgery under general anesthesia were included. Patients who had emergency surgery, hearing or cognitive impairment, were excluded from the study. Results A total of 120 patients were enrolled, and separated into two groups. There were no statistically significant differences between the groups in terms of demographic characteristics, anesthesia and surgery durations (p &gt; 0.05). In the music group, sedation agitation scores were lower than those in the control group at the postoperative period (3.76 ± 1.64 vs. 5.11 ± 2.13; p &lt; 0.001). In addition; in patients of the music group, the pain level (2.73 ± 1.28 vs. 3.61 ± 1.40) was lower (p &lt; 0.001), requiring less analgesic drugs intake. Conclusion Music therapy, which is a nonpharmacologic intervention, is an effective method, without side effects, leading to positive effects in the awakening, hemodynamic parameters and analgesic requirements in the postoperative period. It is also effective in reducing the anxiety and intraoperative awareness episodes of surgical patients.

title: Evaluation of serum prolidase enzyme activity and oxidative stress in patients with tinnitus

description: Abstract Introduction Tinnitus is defined as the perception of sound in the head or in the head in the absence of external sounds. The cause of tinnitus is still unknown. Objective We aimed to compare the serum levels of total oxidant status, total antioxidant status, serum prolidase enzyme activity and the oxidative stress index in patients with tinnitus to those of normal subjects. Methods Twenty five patients with tinnitus (mean age 34.3) and 25 healthy controls (mean age 37.2) were included in the study. Results Total oxidant status levels in the patient group were significantly higher than in the control group (p = 0.037). The mean total oxidant status value was 2.54 ± 0.95 mmoL/L in the patient group, and 2.06 ± 0.98 mmoL/L in the control group. The mean oxidative stress index level was 0.22 ± 0.10 AU in the patient group, while it was 0.17 ± 0.08 AU in the control group. Oxidative stress index was significantly higher in the patient group (0.026). There was no significant difference between the groups in terms of total antioxidant status values (p = 0.838). The mean serum prolidase enzyme activity level was 202.74 ± 33.56 U/L in the patient group and 175.46 ± 42.68 U/L in the control group. Serum prolidase enzyme activity levels in the patient group were significantly higher than in the control group (0.040). Conclusion We detected that the total oxidant status, oxidative stress index and serum prolidase enzyme activity levels were higher in patients with tinnitus when compared to the healthy controls. This finding suggests that oxidative stress index and serum prolidase enzyme activity may play a role in the etiopathogenesis of tinnitus.

title: Prevention of upper aerodigestive tract cancer through active search strategies and use of equipped propaedeutics,,

description: Abstract Introduction Upper aerodigestive tract cancer is among the most frequent malignancies and has epidemiological importance worldwide. Most cases are already advanced at the diagnosis, with a strong negative impact on survival and high cost to the government. Campaigns directed against these cancers have often failed in Brazil. Objective To evaluate the effectiveness of screening for upper aerodigestive tract cancers, using active search strategies and the use of equipped propaedeutics. Methods A cross-sectional, prospective, descriptive, analytical and exploratory study, since its objectives are based on the visualization of cancerous lesions in a sample consisting of individuals with risk factors, aiming to expand the necessary knowledge for cancer detection, aiming at secondary prevention of the oral cavity, oropharynx, larynx and hypopharynx cancer. Results A total of 16.7% of precancerous lesions and 0.5% of cancer lesions located in the upper aerodigestive tract were clinically visualized. Conclusion The method was effective in the identification of precancerous lesions for the purpose of secondary prevention, but equally important against upper aerodigestive tract cancer, since in the present study the chance of finding the latter was increased by 22.7, showing it is an alternative for future campaigns against the disease.

title: Comparison of postoperative morbidity between conventional cold dissection and bipolar electrocautery tonsillectomy: which technique is better?

description: Abstract Introduction Tonsillectomy is one of the most common surgeries in the head and neck worldwide. This operation is carried out by different methods, the most frequent of which are the cold dissection and bipolar electrocautery techniques. Objective This study was conducted to assess and compare postoperative morbidity between cold dissection and bipolar electrocautery. Methods This prospective randomized clinical trial was performed on 534 patients who underwent tonsillectomy in Vali-e-Asr Hospital of Birjand, east of Iran from October, 2013 to October, 2015. The patients were systematically selected for cold dissection technique or bipolar electrocautery technique groups. Time of surgery, amount of intraoperative blood loss, postoperative hemorrhage, the intensity of local pain 4 and 24 hours after operation and nausea and/or vomiting were recorded and compared in the two groups to decide which technique is better. The data were analyzed in SPSS software (ver-22). The p-value less than 0.5 was considered significant. Results In this study, 51.7% of the cold dissection technique patients and 50.6% of the bipolar electrocautery technique participants were male. Compared to the cold dissection technique, the average intraoperative blood loss was significantly lower (p &lt; 0.001) in the bipolar electrocautery technique group, while the intensity of local pain 4 and 24 hours after the operation was significantly higher (p &lt; 0.001). Other variables showed no significant differences between the two groups. Conclusion Based on the findings of the present investigation, the bipolar electrocautery technique is suggested for tonsillectomy in children, while the cold dissection technique is preferred for adult patients.
