Evaluation of Nasal Mucociliary Clearance Time in Patients with Schizophrenia.

Nasal mucociliary clearance time (NMCT) is prolonged in patients with olfactory disorders. It is essential to differentially diagnose conductive and neural olfactory disorders. Here, we used the mucociliary clearance test to investigate a disease associated with neural olfactory disorders, i.e. schizophrenia. Data on age, gender, and duration of disease were collected. The study involved 56 schizophrenia patients and 56 healthy controls. There was no significant difference between the groups regarding age and gender (p = 0.459 and p = 0.768 respectively). Mean NMCT of patients with schizophrenia was 13.82 ± 3.22 min and mean NMCT of healthy controls was 10.15 ± 2.94 min. There was significant difference between the groups regarding NMCT (p < 0.001). In the patient group, there was a significant positive correlation between duration of disease, age, and NMCT (Pearson r = 0.286, p = 0.032, and Pearson r = 0.522, p < 0.001 respectively). This study has shown a prolonged NMCT in patients with schizophrenia compared to the healthy control group.

Effects of Anatolian Propolis and Hypertonic Saline Combination Nasal Spray on Allergic Rhinitis Symptoms: A Prospective, Multicenter Study.

Objectives: This study aimed to evaluate how Rhinapi nasal spray affects symptoms of allergic rhinitis. Methods: In this prospective, multicenter, observational study, 10,000 patients (comprising 5028 males and 4972 females) exhibiting symptoms of allergic rhinitis (namely, nasal discharge, sneezing, nasal itching, and nasal obstruction) from different centers in different regions of Turkey were enrolled in the study between March 2022 and March 2023. All the patients wanted to participate in the study and were administered Rhinapi one puff to each nostril three times a day, for a period of 3 weeks. Total symptom scores, quality of life (QoL) scores, and otolaryngological examination scores were evaluated before and 3 weeks after treatment. Results: The scores for discharge from the nose, sneezing, nasal pruritus, and blockage of the nose all indicated improvement when compared to pre-medication and post-medication. This difference achieved statistical significance (P < .001). The mean total symptom score fell following treatment (P < .001): whilst the score was 11.09 ± 3.41 before administering Rhinapi; after administration, the average score was 6.23 ± 2.41. The mean QoL scores also altered after medication (P < .001), improving from a mean value of 6.44 ± 1.55 to a mean of 7.31 ± 1.24. Significant improvement was also noted in the scores for conchal color and degree of edema after the treatment had been administered (P < .001). Conclusion: The study demonstrates that Rhinapi nasal spray decreases total symptom scores, and results in improved QoL and otolaryngological examination scores. Propolis spray may be recommended for patients with allergic rhinitis alongside other treatments.

Evaluation of Nasal Mucociliary Clearance as an Indicator of Nasal Function in Obsessive-Compulsive Patients: A Cross-Sectional Study.

This clinical study aimed to compare the mucociliary clearance time in patients with OCD, a disease associated with neural olfactory disorders, with a healthy control group. The mucociliary clearance time of fifty-one patients with OCD and fifty-two healthy patients (control group) was compared. The saccharin nasal mucociliary clearance test (NMCT) was applied and recorded the sociodemographic data of all participants. The NMCT was longer in OCD patients than healthy controls. There was no statistically significant difference in sociodemographic data between the groups. Our results show that olfactory transmission pathways may be affected in OCD patients. Supplementary Information: The online version contains supplementary material available at 10.1007/s12070-023-03972-2.

Comparison of frontal QRS-T angle of patients with nasal septal deviation with healthy controls.

BACKGROUND: This study compares frontal QRS-T angle (fQRS-T) in electrocardiogram (ECG) examinations of people with nasal septal deviation (NSD) with healthy controls (HC). METHODS: Eighty-two patients whom a radiologist with paranasal computed tomography definitively diagnosed with NSD were included in the study. 101 individuals without NSD were selected as HC. RESULTS: Compared to the HC group, the fQRS-T in was considerably wider in patients with NSD (p < .001). According to Spearman correlation analysis, fQRS-T and NSD angle, and platelet lymphocyte ratio (PLR) were significantly correlated (p = .021, p < .001, and p = .003, respectively). In linear regression analysis where the fQRS-T was taken as a dependent variable, NSD angle and PLR predicted the fQRS-T significantly and positively (F(5.76) = 8.451, R2 = 0.357, Adjusted R2 = 0.315 and p < .001). CONCLUSION: In this study, fQRS-T was significantly higher in patients with NSD. In future studies, fQRS-T can be compared before and after septoplasty in NSD patients.

Dietary supplements used by otolaryngology patients in Turkey during the COVID-19 pandemic: A cross-sectional survey.

Introduction: This study investigated the characteristics of dietary supplement (DS) use of patients who attended the otolaryngology clinic at a university training and research hospital in Turkey during the pandemic, including patients who had experienced Coronavirus disease 2019 (COVID-19). Methods: This cross-sectional study was conducted between March and September 2021. 277 literate patients aged ≥ 18 years who attended the otolaryngology clinic were enrolled. A questionnaire was used to collect sociodemographic data, as well as data on DS use during the pandemic. The questionnaire was administered in a face-to-face setting by a single researcher. Results: Approximately half of the participants (50.18%) took DSs during the pandemic and 67.18% of those who experienced COVID-19 infection used DSs during their illness. The most commonly used supplements were vitamin C (43.16%) and D (33.09%), along with herbal supplements such as lemon (54.68%), garlic (46.76%), ginger (46.04%), and thyme (43.88%). In total, 85.23% of the patients primarily used DSs to enhance their immunity, while 32.95% used them to prevent cough, and 26.14% to improve breathing. The majority of the patients (85.23%) felt benefit from DSs. Typically, the patients obtained information about DSs from doctors (32.37%) or friends and relatives (29.49%), and most of them used the supplements without first consulting a doctor (63.64%). Conclusion: DSs were commonly used by otolaryngology patients during the COVID-19 pandemic, particularly to enhance immunity. Although the majority of patients reportedly benefited from these products, most of them did not inform their physicians that they were using them and often obtained information from unofficial sources.

Evaluation of frontal QRS-T angle values in electrocardiography in patients with chronic rhinosinusitis.

BACKGROUND: Chronic Rhinosinusitis (CRS) refers to inflammation of the paranasal sinuses and nasal mucosa. Electrocardiographic indicators of ventricular repolarization have been shown to correlate with systemic inflammation parameters. Recently, the frontal QRS-T (fQRS-T) angle has been accepted as a new indicator of ventricular depolarization and repolarization heterogeneity. The (fQRS-T) angle is recommended in predicting the risk of malignant ventricular arrhythmia. In this study, we aimed to evaluate the ventricular arrhythmia potential in patients with chronic rhinosinusitis by examining the relationship between fQRS-T angle on ECG and inflammation markers. METHODS: Inflammatory markers as well as electrocardiographc (ECG) f(QRS-T) angle, QRS duration, QT interval and corrected QT interval were examined in 54 patients with CRS versus 56 healthy control subjects. RESULTS: The f(QRS-T) angle was significantly higher in CRS patients than in healthy controls (p < .001). The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and monocyte-to-lymphocyte ratio (MLR) were significantly higher in CRS patients compared to healthy controls (p < .001, for all). Based on correlation analysis, NLR and f(QRS-T) angles were highly correlated (r = .845, p < .001), and according to the results of linear regression analysis, NLR was independently associated with the f(QRS-T) angle (t = 5.149, Beta = 0.595, p = < 0.001). CONCLUSION: Both f(QRS-T) angle and NLR are significantly increased in CRS patients compared to healthy controls, with increases in NLR also independently associating with increases in f(QRS-T) angle. While the increases in f(QRS-T) angle did not result in clinically alarming absolute values for f(QRS-T), CRS patients might nonetheless be at relatively higher risk for malignant cardiac arrhythmias.

Evaluation of biochemical variables in patients with recurrent aphthous stomatitis.

PURPOSE: We investigated the effects of various biochemical agents on the etiopathogenesis of recurrent aphthous stomatitis (RAS). METHODS: We enrolled 70 RAS patients and 70 healthy volunteers. Peripheral venous blood samples were collected. We performed complete blood counts, then measured the levels of ferritin, vitamin B12, iron, magnesium, phosphorus, calcium, thyroid-stimulating hormone, T3, T4, and 25-hydroxy D3. RESULTS: The groups did not differ in terms of age (p = 0.912) or sex (p = 0.612). The levels of ferritin and 25-hydroxy vitamin D were significantly lower in RAS patients (both p Ë‚ 0.05). CONCLUSION: Vitamin D and/or ferritin deficiency may induce RAS. Measurements of vitamin D and ferritin may assist diagnosis and follow-up.

Effects of the Lunar Cycle, Seasons and the Meteorological Factors on Peripheral Vertigo.

Objective: This study aimed to determine whether peripheral vertigo is related to the lunar cycle, the seasons, or meteorological factors, in patients who presented to the ear, nose, and throat clinic. Methods: All the patients, diagnosed with vertigo between January 2020 and January 2022, were identified through a retrospective review of our hospital database. The clinical and demographic data of the patients were recorded. Daily humidity (minimum, average, and maximum; %), daily temperature (minimum, average, and maximum; °C), daily average and maximum wind speed (m/min), daily air pressure (minimum and average maximum; hPa) and wind direction (degrees) values were noted. Also, the phases of the moon, i.e., first quarter, new moon, last quarter, and full moon periods were determined. Results: A total of 5,432 patients were included in the study. No statistically significant differences were noted among them with respect to the lunar cycle (p=0.233). However, patient density was found to increase in the winter months. Conclusion: This study concluded that the frequency of diseases is related to meteorological factors, nonetheless, no statistical relationship was found between the lunar cycle and the frequency of patient entries.

Salivary gland tumors exhibit distinct miRNA signatures involved in Wnt/ß-Catenin signaling in formalin fixed paraffin embedded tissue samples.

Advances in high-throughput genomic technologies have enabled the identification of numerous selective tumor markers. However, adapting these newly identified markers to clinical practice is not always possible because most RNA molecules, including mRNAs of protein-coding genes and long non-coding RNAs, are not stable under laboratory conditions, making their testing a major challenge. In contrast to long RNA molecules, miRNAs offer a great advantage in that they are relatively stable due to their small size. Accordingly, herein we aimed to determine the expression levels of miRNAs that are involved in Wnt/ß-catenin signaling pathway in formalin fixed paraffin embedded (FFPE) tissue samples of patients with salivary gland tumors. A total of 42 patients with salivary gland tumors were included in the study. The miRNA expression signatures were evaluated using the RT-qPCR. As a result, ß-catenin positivity was observed in all salivary gland tumors without distinguishing between benign and malignant phenotypes. Remarkably, we found that miR-200a and miR-373 were significantly upregulated whereas miR-30c were downregulated in tissues of patients with salivary gland tumors, compared to adjacent healthy tissue samples. In addition, distinct expression signatures of these miRNAs were significantly associated with the clinicopathological findings of patients such as perineural invasion and lymph node metastasis. Additionally, miR-145 and miR-30a were found to be specifically downregulated in a mucoepidermoid carcinoma. Also, miR-26b was selectively increased in pleomorphic adenomas of the salivary gland. Collectively, our findings suggest that these miRNAs may play chief roles in the differential diagnosis of salivary gland tumors.

Effect of septoplasty on left ventricular myocardial performance in patients with nasal septum deviation / Efeito da septoplastia no desempenho miocárdico ventricular esquerdo em pacientes com desvio de septo nasal

Abstract Introduction: Nasal septum deviation is the leading cause of upper airway obstruction. Chronic upper airway obstruction may cause myocardial injury due to chronic hypoxia. Effects of septoplasty on left venticular diastolic and sistolic functions are not well known. The myocardial performance index is an easy-to-apply and reliable parameter that reflects systolic and diastolic cardiac functions. Objective: The present study aimed to investigate the effect of nasal septoplasty on the myocardial performance index in patients with nasal septal deviation. Methods: This prospective study consisted of 50 consecutive patients who underwent septoplasty due to symptomatic prominent C- or S-shaped nasal septal deviation. Transthoracic echocardiogarphy was performed in all patients before and 3 months after septoplasty. Calculated myocardial performance indices were compared. Results: Significantly higher left ventricular myocardial performance index (0.52 ± 0.06 vs. 0.41 ± 0.04, p < 0.001), longer isovolumic relaxation time (95.0 ± 12.5 vs. 78.0 ± 8.6 ms, p < 0.001), longer isovolumic contraction time (45.5 ± 7.8 vs. 39.5 ± 8.6 ms, p < 0.001), longer deceleration time (184.3 ± 32.5 vs. 163.6 ± 45.4 ms, p = 0.004), higher ratio of transmitral early to late peak velocities (E/A) (1.42 ± 0.4 vs. 1.16 ± 0.2, p = 0.006) and shorter ejection time (270.1 ± 18.3 vs. 286.5 ± 25.8 ms, p < 0.001) were observed before septoplasty when compared to values obtained 3 months after septoplasty. Left ventricular systolic ejection fraction was similar before and after septoplasty (63.8±2.8% vs. 64.6±3.2%, p =0.224). Conclusion: Septoplasty surgery not only reduces nasal blockage symptoms in nasal septal deviation patients but also may improve left ventricular performance. Thus, treatment of nasal septal deviation without delay is suggested to prevent possible future cardiovascular events.

Resumo Introdução: O desvio do septo nasal é a principal causa de obstrução das vias aéreas superiores. A obstrução crônica das vias aéreas superiores pode causar lesão miocárdica devido à hipóxia crônica. Os efeitos da septoplastia nas funções diastólica e sistólica do ventrículo esquerdo não são bem conhecidos. O índice de desempenho miocárdico é um parâmetro confiável e fácil de aplicar que reflete as funções cardíacas sistólica e diastólica. Objetivo: Investigar o efeito da septoplastia nasal no índice de desempenho miocárdico em pacientes com desvio de septo nasal. Método: Este estudo prospectivo consistiu em 50 pacientes consecutivos submetidos a septoplastia devido a desvio de septo nasal significativo sintomático em S ou C. A ecocardiogarfia transtorácica foi feita em todos os pacientes antes e 3 meses após a septoplastia. Os índices de desempenho miocárdico calculados foram comparados. Resultados: Um valor de indice de desempenho miocárdico ventricular esquerdo significantemente maior (0,52 ± 0,06 vs. 0,41 ± 0,04, p < 0,001), tempo mais longo de relaxamento isovolumétrico (95,0 ± 12,5 vs. 78,0 ± 8,6 ms, p < 0,001), tempo mais longo de contração isovolumétrica (45,5 ± 7,8 vs. 39,5 ± 8,6 ms, p < 0,001), tempo de desaceleração mais longo (184,3 ± 32,5 vs. 163,6 ± 45,4 ms, p = 0,004), maior razão de pico de velocidade transmitral precoce e tardia (E / A) (1,42 ± 0,4 vs. 1,16 ± 0,2, p = 0,006) e menor tempo de ejeção (270,1 ± 18,3 vs. 286,5 ± 25,8 ms, p < 0,001) foram observados antes da septoplastia quando comparados aos valores obtidos 3 meses após a septoplastia. A fração de ejeção sistólica do ventrículo esquerdo foi semelhante antes e após a septoplastia (63,8 ± 2,8% vs. 64,6 ± 3,2%, p = 0,224). Conclusão: A cirurgia de septoplastia não apenas reduz os sintomas em pacientes com desvio de septo nasal, mas também pode melhorar o desempenho ventricular esquerdo. Assim, o tratamento precoce do desvio de septo nasal é sugerido para prevenir possíveis eventos cardiovasculares futuros.

Deciphering miRNAs associated with cellular stress response and apoptosis mechanisms regulated by p53 activity in patients with lower lip cancer.

Cancers of the lips and oral cavity are a leading cause of death worldwide. Although they account for only 2% of the global cancer burden, they significantly affect the comfort of patients and eventually lead to a person's death. Also, defects in the cellular stress response and apoptosis mechanisms regulated by p53 activity is an important hallmark of cancer cells. Here, we aimed to decipher miRNAs associated with cellular stress response and apoptosis mechanisms regulated by p53 activity in patient with lower lip cancer and reveal the association of these miRNAs with the clinical course of the disease. The present research included a total of 40 eligible individuals with pathologically confirmed lower lip cancer diagnosis. Formalin-fixed, paraffin-embedded (FFPE) tissue samples of patients were obtained, and miRNAs expressions were analyzed by qPCR. Immunohistochemistry was used to determine p53 and Ki67 expression status. While three of these miRNAs (miR-130a, -375, and -128a) were found to be elevated in tumor cells compared to normal tissues of lower lip cancer patients, five were downregulated (let-7a, -7b, -7c, and miR-138, -23a), but only three were significantly altered. Particularly, we identified three miRNA signatures in which miR-128a was significantly upregulated and miR-23a and let-7c were significantly downregulated in patients with lower lip cancer. Remarkably, let-7c identified to be a promising prognostic factor for lip cancer. Our findings demonstrate that these miRNAs play important regulatory roles in lower lip cancer pathobiology, highlighting their potential relevance in diagnosis and prognosis of these patients. Moreover, these miRNAs can be targeted in future therapeutic interventions against lower lip cancer.

Evaluation of the relationship between temporomandibular joint disorders and tinnitus with computed tomography.

PURPOSE: This study aimed to radiographically determine tinnitus and joint disorders by evaluating glenoid fossa depth and the horizontal angle of the ramus mandible in patients with isolated temporomandibular joint disorder and temporomandibular joint disorder with tinnitus by computed tomography (CT). METHODS: In total, eighty two patients with temporomandibular disorders (TMDs) (forty two patients with tinnitus; forty patients without tinnitus) were evaluated using CT. CT images were analysed according to glenoid fossa depth and the horizontal angle of the ramus. RESULTS: A total of 82 cases 43 (52.4%) female and 39 (47.6%) male were included. The distribution of gender was not significantly different between the TMD patients and the TMD-tinnitus patients (p >0.05). The mean age of the patients with isolated TMD was 31.70 ± 9.68 years, and the mean age of the patients with TMD-tinnitus was 34.07 ± 11.72 years. Comparisons were made of the right and left glenoid fossa depths of the patients with TMD and TMD-tinnitus, respectively. There was a statistically significant difference between the right glenoid fossa depths (p = 0.016) also there was also a statistically significant difference between the left glenoid fossa depths (p = 0.049). CONCLUSION: Our study revealed that decreased glenoid fossa depth may be associated with an increased incidence of tinnitus in TMD patients by the way temporomandibular joint and ear can affect each other in diseases such as tinnitus due to their close anatomical relationship.

Evaluation of the associations between maxillary sinus dimensions and adenoid hypertrophy using multislice computed tomography.

INTRODUCTION: Adenoid hypertrophy is especially common in childhood, raising the concern that such growth might affect maxillary sinus volumes during the developmental period. This study evaluated the developmental relationships between maxillary sinus volumes and adenoid hypertrophy via computed tomography. MATERIALS AND METHODS: It was examined computed tomographic images of 118 individuals: 61 boys and 57 girls. The participants were divided into a healthy control group (n = 59) and an experimental group (with adenoid hypertrophy) (n = 59). Raw data were recorded in DICOM format and analysed using the ITK-SNA algorithm; it was measured the right, left, and total maxillary sinus volumes and adenoid tissue sizes. RESULTS: It was found significant between-group differences in the three maxillary sinus volumes and adenoid tissue dimensions (linear maximum anterior and posterior depth; maximum upper and lower height, and maximum width to the right and left) (all p<0.001). On the contrary, there was no significant difference according to sex in terms of either maxillary sinus volumes or linear adenoid tissue measurements. Maxillary sinus volumes increased significantly according to age in both groups. CONCLUSION: Adenoid hypertrophy decreases the maxillary sinus volumes, regardless of sex. The impacts of adenoid growth on maxillary sinus aeration and sinus disease should be further investigated.

Clinical significance of Vimentin Antisense RNA 1 and its correlation with other epithelial to mesenchymal transition markers in oral cancers.

Oral squamous cell carcinoma (OSCC) is the most common form of malignant tumor in the head and neck region worldwide. Hence, the identification of biological signatures with high diagnostic and therapeutic potential for OSCC will be of great clinical importance. Epithelial to mesenchymal transition (EMT) is a key driver of malignant transformation of human tumors including OSCC. Loss of epithelial properties and gain of mesenchymal cell properties is one of the most important hallmarks of malignant tumors. Although much has been reported on the protein components of the EMT process, studies on the non-protein coding components are quite limited. Consequently, here we sought to explore biological significance of VIM antisense RNA 1 (VIM-AS1) in OSCC. A total of 36 patients diagnosed with oral cancer were recruited for the study. Formalin-fixed paraffin embedded (FFPE) tissue samples of patients were obtained from pathology archive. For the gene expression analysis, quantitative RT-PCR was used. We also analyzed the expression levels of E-cadherin and Vimentin. Notably, it was found that the expression levels of VIM-AS1 and Vimentin were significantly elevated, while the expression of E-cadherin was downregulated in OSCC. Deregulation of VIM-AS1 was associated with the clinicopathological features of OSCC patients. ROC analysis also showed that VIM-AS1 is an independent diagnostic biomarker for OSCC. Consequently, our findings suggest a chief role for VIM-AS1 in oral cancers.

RESULTS: Significantly higher left ventricular myocardial performance index (0.52 ±â€¯0.06 vs. 0.41 ±â€¯0.04, p <  0.001), longer isovolumic relaxation time (95.0 ± 12.5 vs. 78.0 ± 8.6 ms, p <  0.001), longer isovolumic contraction time (45.5 ± 7.8 vs. 39.5 ± 8.6 ms, p <  0.001), longer deceleration time (184.3 ± 32.5 vs. 163.6 ± 45.4 ms, p =  0.004), higher ratio of transmitral early to late peak velocities (E/A) (1.42 ± 0.4 vs. 1.16 ± 0.2, p =  0.006) and shorter ejection time (270.1 ± 18.3 vs. 286.5 ± 25.8 ms, p <  0.001) were observed before septoplasty when compared to values obtained 3 months after septoplasty. Left ventricular systolic ejection fraction was similar before and after septoplasty (63.8±2.8% vs. 64.6±3.2%, p  = 0.224). CONCLUSION: Septoplasty surgery not only reduces nasal blockage symptoms in nasal septal deviation patients but also may improve left ventricular performance. Thus, treatment of nasal septal deviation without delay is suggested to prevent possible future cardiovascular events.

Evaluation of Postinfection Hearing with Audiological Tests in Patients with COVID-19: A Case-Control Study.

BACKGROUND: Some viral infections can cause congenital or acquired unilateral or bilateral hearing loss. It is predicted that the coronavirus disease 2019 (COVID-19) virus, which can affect many systems in the body, may also have a negative effect on hearing. PURPOSE: This study evaluated the effects of COVID-19 infection on pure-tone average. RESEARCH DESIGN: A case-control study. MATERIALS AND METHODS: A total of 104 volunteers (48 control, 56 experimental group) who applied to the ENT clinic of Adiyaman University Training and Research Hospital were included in this study. After the detailed clinical examination and medical history, 13 volunteers of the experimental group and 5 volunteers from the control group were excluded from the study. In this way, each group consisted of 43 volunteers. While the experimental group consisted of patients who did not have any hearing problems before but had COVID-19. The control group consisted of healthy volunteers who did not have any hearing problems and were not infected with COVID-19. Audiological test was applied to all volunteers to determine their pure-tone average. On the data obtained, it was analyzed whether COVID-19 affects the pure-tone average and how it changes according to variables such as age and gender. RESULTS: The evaluation of the 43 (50.0%) COVID-19-positive patients and 43 (50.0%) healthy controls showed no significant differences (p > 0.05) at 250 and 500 Hz, whereas at 4000, 6000, and 8000 Hz, the two groups differed significantly. In addition, significant differences were found in the left and right ears at 1000 and 2000 Hz (p < 0.05). The differences between the two groups in the pure-tone average of the left and right ear were statistically significant (p < 0.05). However, there were no significant sex-based differences in the pure-tone average between males and females (p > 0.05) CONCLUSION: The pure-tone average of COVID-19 positive patients was significantly worse than those of the healthy control group. Thus, COVID-19 should also be considered in patients presenting with unexplained hearing loss. Further studies should investigate the effects of COVID-19 on hearing and the underlying pathophysiology.

Evaluation of Tp-e interval, Tp-e/QT ratio and index of cardiac-electrophysiological balance in patients with tinnitus.

BACKGROUND: Tinnitus is a common auditory symptom. Dysfunction in the autonomic nervous system (ANS) is an essential part of the etiopathogenesis of tinnitus. ANS regulates heart rate and heart rhythm and can lead to ventricular repolarization changes, which can cause malignant ventricular arrhythmias. T wave peak-to-end T(p-e) interval and T(p-e)/QT ratio are known ventricular arrhythmia indexes, and the index of cardiac-electrophysiological balance (iCEB) is a novel index that can be used to predict the risk of malignant ventricular arrhythmia. The goal of the study was to investigate these ventricular arrhythmia indexes in patients with tinnitus. METHODS: The study population consisted of 240 patients with tinnitus and 240 healthy subjects. A standard 12-channel surface electrocardiogram was applied to both groups. T(p-e) interval, QT interval and QRS duration were determined. Corrected QT (QTc) was determined via Bazett's formula. To predict ventricular arrhythmia, iCEB (QT/QRS), T(p-e)/QT, corrected iCEB (QTc/QRS) and T(p-e)/QTc values were determined and compared between groups. RESULTS: Compared to the control group, QT (376.46 ± 36.54 vs 346.52 ± 24.51 ms), QTc (426.68 ± 24.68 vs 390.42 ± 24.04 ms), T(p-e) (75.86 ± 14.68 vs 62.42 ± 8.64 ms), T(p-e)/QT (0.201 ± 0.06 vs 0.180 ± 0.01) and T(p-e)/QTc (0.177 ± 0.06 vs 0.159 ± 0.02) were significantly higher in patients with tinnitus (p < 0.001 for all). QT/QRS (3.92 ± 0.68 vs 3.56 ± 0.32) and QTc/QRS (4.44 ± 1.03 vs 4.01 ± 0.64) were also significantly higher in patients with tinnitus (p = 0.018 and p = 0.008, respectively). In addition, significant positive correlations were found between T(p-e), T(p-e)/QTc ratio and disease duration (r = 0.792, p < 0.001; r = 0.500, p < 0.001, respectively). CONCLUSION: As a result, patients with tinnitus may have an increased risk of malignant ventricular arrhythmia.

Assessment of mucociliary clearance as an indicator of nasal function in patients with COVID-19: a cross-sectional study.

PURPOSE: We assessed the effects of COVID-19 infection on nasal mucociliary activity. METHODS: The study was conducted in the pandemic wards of Adiyaman University Training and Research Hospital during April and May 2020. All patients admitted to the COVID-19 pandemic wards during the study period were invited to participate in the study. The study included 40 adults who agreed to participate and underwent a mucociliary clearance test successfully. The primary outcome was mucociliary clearance time and the secondary variables of interest were age, sex, and sino-nasal outcome test-22 scores. The control group included 40 concomitant healthy patients who visited the outpatient ear, nose and throat clinic with non-nasal symptoms. RESULTS: The study included 40 COVID-19-positive patients and 40 healthy controls. The mean mucociliary clearance times of the study (15.53 ± 5.57 min) and control (9.50 ± 3.70 min) groups were significantly different (Z = 4.675, p < 0.001). However, the mucociliary clearance time was not significantly different between males and females (t = 0.590, p = 0.558). CONCLUSIONS: Nasal mucociliary clearance time was prolonged in COVID-19 patients compared to healthy controls. Thus, we conclude that smell and taste are crucial symptoms that should not be overlooked in patients suspected of COVID-19 disease.
