The effect of autosomal dominant polycystic kidney disease on mucociliary clearance.

PURPOSE: Autosomal dominant polycystic kidney disease (ADPKD) is a renal disease with genetic transmisson. Mutations in the PKD1 and PKD2 genes, which encode integral membrane proteins of the cilia of primary renal tubule epithelial cells, are seen in ADPKD. The aim of this study was to evaluate the sinonasal epithelium, which is epithelium with cilia, by measuring the nasal mucociliary clearance time, and to investigate the effect of ADPKD on nasal mucociliary clearance. METHODS: The study included 34 patients, selected from patients followed up in the Nephrology Clinic, and 34 age and gender-matched control group subjects. The nasal mucociliary clearance time (NMCT) was measured with the saccharin test. RESULTS: The mean age of the study subjects was 47.15 ± 14.16 years in the patient group and 47.65 ± 13.85 years in the control group. The eGFR rate was determined as mean 72.06 ± 34.26 mL/min in the patient group and 99.79 ± 17.22 mL/min in the control group (p < 0.001). The NMCT was determined to be statistically significantly longer in the patient group (903.6 ± 487.8 s) than in the control group (580 ± 259 s) (p = 0.006). CONCLUSIONS: The study results showed that the NMCT was statistically significantly longer in patients with ADPKD compared to the control group, but in the linear regression analysis results, no correlation was determined between eGFR and NMCT.

Assessment of Subjective and Objective Voice Analysis According to Types of Sulcus Vocalis.

INTRODUCTION: Sulcus vocalis (SV) subtypes are difficult to diagnose. Non-invasive techniques are sometimes not feasible in the diagnosis. The study aims to demonstrate the effectiveness and applicability of objective and subjective voice analysis combined with videolaryngostroboscopic examination (VLS) in the diagnosis of SV types. MATERIAL AND METHODS: This is a retrospective study that includes patients who presented to Phoniatric outpatient clinic with complaints related to voice and diagnosed with SV on VLS examination between 2017-2020. The SV type was determined based on VLS findings and the patients were categorized into respective groups. Between- and within-group assessment of objective and subjective voice analysis of SV types was conducted. RESULTS: 47 patients were included in the study; Type I, Type II, Type III SV patients were 16, 17, and 14 in number, respectively. Fundamental frequency (F0) and Shimmer (%) values were significantly high in Type II and III SV cases, whereas the Maximum Phonation Time (MPT) was significantly low. GRBAS, Voice Handicap Index -10 (VHI-10), Reflux Symptom Index (RSI) scores were statistically significantly high in pathological SV and Voice Related Quality of Life (V-RQOL) scores were low. A moderate correlation between VHI-10 and V-RQOL and between RSI and V-RQOL was detected. CONCLUSIONS: Objective and subjective voice analysis in Type II and III SV show a significant difference compared to Type I SV. The use of objective and subjective voice analysis combined with VLS examination can be helpful in the diagnosis of SV types.

Voice Disorders in Lower Primary School Teachers: An Observational Study.

INTRODUCTION: Voice problems are very common among teachers, and etiology-based methods are used in the diagnosis and treatment process. Our study aims to reveal the changes in subjective voice analysis during the diagnosis and treatment process of dysphonia in lower primary school teachers. METHODS: The nature of the study is a prospective observational one designed for lower primary school teachers in Kahramanmaras conducted between the year 2015 and 2019 and evaluations for parameters including sociodemographic characteristics, laryngeal lesions and pre- and post-treatment scales such as Voice Handicap Index-10 (VHI-10), Reflux Symptom Index (RSI) and Hospital-Anxiety Depression Scale (HADS) for treatment subgroups were made. Statistical analysis was analyzed using SPSS. RESULTS: Three hundred and fifty-one lower primary school teachers were included in the study. A statistically significant difference was found for the development of dysphonia in terms of sociodemographic features such as smoking, professional experience and crowdedness of classroom. Changes in RSI, VHI-10 and HADS values after treatment were clinically significant in all treatment groups. While there was a significant post-treatment improvement in terms of RSI in patients with granuloma and laryngopharyngeal reflux disorders, the VHI-10, and HADS assessments revealed a significant difference in clinical recovery compared to laryngeal lesions. CONCLUSION: The RSI, VHI-10 and HADS values for various laryngeal pathologies were found to be high in dysphonic teachers. An improvement was observed in the scale scores upon the application of treatment modalities. This situation emphasizes the importance of questionnaire survey in the diagnosis, treatment, and follow-up process of dysphonia.

The effect of type 1 diabetes mellitus on voice in pediatric patients.

PURPOSE: The aim of this prospective case-control study was to determine the effect on the voice of type 1 diabetes mellitus (T1DM) in paediatric patients. MATERIALS AND METHODS: The study included patients aged 6-18 years followed up for at least 1 year because of T1DM, and a control group of age and gender-matched healthy volunteers. Following an Ear, Nose, and Throat (ENT) examination, all subjects underwent flexible endoscopic laryngeal examination. Fasting venous blood samples were taken in the morning for the examination of fasting blood glucose (FBG), HgbA1C, and kidney, liver, and thyroid function tests. Data were recorded from the patient files of age, gender, comorbidities, and the development of diabetes-related complications. Voice recordings were taken and the Voice Handicap Index (VHI)-10 form was completed. The patients and control group were compared in respect of the parameters of fundamental frequency, jitter, shimmer, and acoustic voice quality index (AVQI). RESULTS: Evaluation was made of 64 children and adolescents as 32 in the patient group (Group 1) and 32 healthy control subjects (Group 2). Group 1 comprised 17 females and 15 males with a mean age of 12.75 ± 3.23 years. Group 2 comprised 17 females and 15 males with a mean age of 12.75 ± 3.33 years. In Group 1, mean disease duration was 5.21 ± 3.17 years (range, 1-13 years), the FBG value was mean 216.6 ± 122.3 mg/dl, mean HgbA1c was 10.7 ± 2.8, as ≤ 7 in 4 patients, 7-9 in 4, and > 9 in 24. Maximum phonation time (MPT) was determined as 10.66 ± 3.6 secs in Group 1 and 12.11 ± 4.43 in Group 2. VHI was determined as 2.33 ± 3 in Group 1 and 2.31 ± 2.77 in Group 2. No statistically significant difference was determined between the groups was determined in respect of acoustic analysis, perturbation parameters, AVQI and body mass index. CONCLUSIONS: This study is the first to have investigated the effects of T1DM on the voice in paediatric patients. The study results showed that the AVQI value was higher in the patient group but not to a statistically significant level. Therefore, there is a need for further studies with larger samples. The current study can be of guidance for further studies in this field.

Does Maras powder affect the nasal mucociliary clearence?

PURPOSE: Many studies have been conducted about the effect of cigarettes and other tobacco products on mucociliary clearance. However, there has been no study of the relationship between mucociliary clearance and Maras powder, which is a smokeless tobacco product. The aim of this study was to evaluate the effect of Maras powder use on mucociliary clearance through comparisons with cigarette smokers and those who used no tobacco products. METHODS: The study included 75 male volunteers, aged 23-54 years. Group 1 (n: 25) comprised subjects who do not use any tobacco products, Group 2 (n: 25) those who smoked cigarettes, and Group 3 (n: 25) those who used Maras powder. The saccharin test was used to evaluate mucociliary clearance and the time was recorded in seconds. The groups were statistically compared in respect of mean age and mucociliary clearance time (MCCT). RESULTS: The mean MCCT was determined to be 645.8 ± 200 secs for the whole study sample, 497 ± 108 secs for Group 1, 796 ± 200 secs for Group 2, and 644 ± 161 secs for Group 3. The difference between the groups in respect of MCCT was statistically significant (p < 0.001). No statistically significant difference was determined between the groups in respect of mean age (p = 0.730). CONCLUSION: The study results demonstrated that the nasal mucociliary clearance time was prolonged both by cigarettes and by the use of Maras powder, and that this time was prolonged more by cigarette smoking than the use of Maras powder.

Management of Basal Cell Carcinomas: Clinical Experience.

Objective: Basal cell carcinomas (BCC) mostly originate from the head and neck region. Main goal in BCC treatment is to achieve both aesthetic and functional results while observing the principles of tumor surgery. We report our experience regarding the clinical, histopathological features and surgical treatment results of head and neck basal cell carcinomas in the light of the literature. Methods: Files of patients with head and neck BCCs treated surgically in two university hospitals were retrospectively analyzed. Sociodemographic variables, location and size of tumor, pathological subtype, recurrence ratio, complications and technique of reconstruction were evaluated. Results: We analyzed 119 tumoral lesions in 105 patients of whom 55 (52.4%) were male and 50 (47.6%) were female. Their mean age was 67.3±12 years. The nasal region was the most common location area (n=42, 35.3%). Mean tumor size was 12.6 mm and tumor size range was 2-85 mm. The most commonly used reconstruction techniques were flap surgery, followed by primary closure, and skin grafts. Conclusion: It is important to remove the tumor with a clear surgical margin at least 4 mm and evaluate the five surgical margins with frozen sections intraoperatively. Operations are often performed under local anesthesia and are well tolerated by patients. The most common flaps used in the reconstruction are not only easy to learn but also sufficient in most cases. Skin grafts are good choices in defects located in the cavum concha and the external meatus.

Characteristics of Benign Paroxysmal Positional Vertigo Following an Earthquake.

INTRODUCTION: Benign Paroxysmal Positional Vertigo (BPPV) is a commonly encountered peripheral vestibular disorder. People exposed to massive earthquakes experience intense and long-term problem associated with dizziness. The purpose of our study is to investigate this relationship and to demonstrate the efficacy of the treatment modalities used in the management of patients with post-earthquake dizziness. METHODOLOGY: The study was carried out by examining the retrospective records of patients who presented with dizziness to the otorhinolaryngological outpatient unit before and after the Elazig earthquake that occurred on 24th Jan 2020. Parameters evaluated include patients' age and gender, onset of dizziness, accompanying symptoms and comorbidities, videonystagmography (VNG) findings, pre- and post-treatment Visual Analogue Scale (VAS), Dizziness Handicap Inventory (DHI), and Hospital Anxiety and Depression Scale (HADS). RESULTS: The number of patients who presented with dizziness to our outpatient clinic after the earthquake and were included in our study totaled 84. The number of patients who visited the outpatient clinic before the earthquake was identified to be 75. In the earthquake related group, while there was a statistically significant difference between residual symptoms (RS) and the need for repetitive repositioning maneuvers, there was no statistically significant difference detected for age, gender, and comorbidities. Also, no statistically significant difference was found in the pre- and post-treatment assessments of VAS, DHI, and HADS median values in the earthquake group. CONCLUSION: There was a remarkable increase in the number of patients presenting with dizziness in the early post-earthquake period. Management of these patients may differ from the classic BPPV. Residual symptoms appearing after performing repositioning maneuvers can be more commonly seen among these patients.

Bilateral Laryngocele Causing Epiglottic Deformity and Upper Airway Obstruction.

Laryngocele is the cystic dilatation of laryngeal ventricle. Most cases are asymptomatic and incidentally diagnosed in radiologic examinations. Although the etiology is unclear, obstruction, laryngeal pressure, congenital defects are possible risk factors. Computed tomography is the best method for diagnosis. Endoscopic, external or combined approaches have been described in the surgical treatment. Laryngocele should be kept in mind in patients with acute upper airway obstruction. Such patients may require tracheostomy. Some patients with laryngocele can also have laryngeal cancer, in which case direct laryngoscopy must be performed. This report presents a case with respiratory distress associated with bilateral laryngocele, and his management in the light of the literature.

Mucociliary clearance in patients with continuous ambulatory peritoneal dialysis.

INTRODUCTION: Mucociliary clearance (MC) is a critical defense mechanism for the protection of the entire respiratory system. Nasal colonization of some pathogens and chronical nasal infections are important risk factors for peritonitis. Any disturbance in the MC causes stasis of secretions and secondary infections. OBJECTIVE: The aim of the study was to evaluate the patients with chronic kidney disease (CKD) receiving continuous ambulatory peritoneal dialysis (CAPD) in terms of nasal MC. More specifically, the goal is to investigate the possible correlation between the nasal MC and peritonitis. METHODS: Forty CAPD patients and 39 healthy volunteers were involved in the study. The nasal MC was evaluated with the saccharin test, in which a 1mm diameter saccharin particle was carefully placed on the antero-medial surface of inferior nasal concha. The time taken by the subjects from the placement of particle to the perception of the sweet taste was taken as mucociliary clearance time (MCT). The groups were compared in terms of MCT. The patient group was evaluated in terms of a peritonitis history, and the correlations with MC were analyzed. RESULTS: Patient group with CKD consisted of 16 females and 24 males with a mean age of 32.4 years; healthy individuals in the control group consisted of 17 women and 22 men with a mean age of 33.3 years. There was not a significant difference in terms of mean MC time in patients with CKD when compared with the individuals in the control group. The comparison between the mean MCT in the patients who had a history of peritonitis and patients without peritonitis was statistically significant (p<0.05). CONCLUSIONS: Unique for being conducted with patients in continuous ambulatory peritoneal dialysis, the current study shows that although the MC of CKD patients and healthy individuals is similar, patients with low rates of MC appear to present an increased incidence of peritoneal infection. Considering the small sample investigated, an invitation to future confirmatory studies would be appropriate.

Fingolimod Alters Tissue Distribution and Cytokine Production of Human and Murine Innate Lymphoid Cells.

Sphingosine-1 phosphate receptor 1 (S1PR1) is expressed by lymphocytes and regulates their egress from secondary lymphoid organs. Innate lymphoid cell (ILC) family has been expanded with the discovery of group 1, 2 and 3 ILCs, namely ILC1, ILC2 and ILC3. ILC3 and ILC1 have remarkable similarity to CD4+ helper T cell lineage members Th17 and Th1, respectively, which are important in the pathology of multiple sclerosis (MS). Whether human ILC subsets express S1PR1 or respond to its ligands have not been studied. In this study, we used peripheral blood/cord blood and tonsil lymphocytes as a source of human ILCs. We show that human ILCs express S1PR1 mRNA and protein and migrate toward S1P receptor ligands. Comparison of peripheral blood ILC numbers between fingolimod-receiving and treatment-free MS patients revealed that, in vivo, ILCs respond to fingolimod, an S1PR1 agonist, resulting in ILC-penia in circulation. Similarly, murine ILCs responded to fingolimod by exiting blood and accumulating in the secondary lymph nodes. Importantly, ex vivo exposure of ILC3 and ILC1 to fingolimod or SEW2871, another S1PR1 antagonist, reduced production of ILC3- and ILC1- associated cytokines GM-CSF, IL-22, IL-17, and IFN-γ, respectively. Surprisingly, despite reduced number of lamina propria-resident ILC3s in the long-term fingolimod-treated mice, ILC3-associated IL-22, IL-17A, GM-CSF and antimicrobial peptides were high in the gut compared to controls, suggesting that its long term use may not compromise mucosal barrier function. To our knowledge, this is the first study to investigate the impact of fingolimod on human ILC subsets in vivo and ex vivo, and provides insight into the impact of long term fingolimod use on ILC populations.

The effect of FoxP3 on tumour stage, treatment response, recurrence and survivalability in nasopharynx cancer patients.

OBJECTIVES: To investigate the relationship between the cell percentage of T regulator (Treg) cells of patients' specimens and disease severity, survivability, recurrence and metastasis in patients who were diagnosed with nasopharyngeal carcinoma (NPC). DESIGN, SETTING AND PARTICIPANTS: Sixty patients who were diagnosed as NPC and treated by the same protocol were enrolled to the study. Patient files were reviewed retrospectively and their clinical and pathological results were recorded. Deparaffinized samples of nasopharyngeal carcinoma patients were stained immunohistochemically with anti-FoxP3 monoclonal antibody. All patients's Anti-FoxP3 stained slides were evaluated by the same pathologist. Stained Treg lymphocytes around the tumoral foci were investigated. Patients were divided into two groups according to the total anti-FoxP3-stained Treg cell counts of the specimens; that is, less than 20% of the total or more than 20% of the total. These groups were compared statistically. MAIN OUTCOME MEASURES: Intensity of FoxP3 which is related to negative tumor response was the main outcome measure. It was evaluated in terms of stage, survival, recurrence and metastasis. RESULTS: The study group consisted of 42 male patients (70%) and 18 female patients (30%). The mean age was 47 ± 14.9. NPC subtypes among the patients were undifferentiated non-keratinized type in 54 patients (90%), differentiated non-keratinized type in 4 patients (6.66%) and keratinized type squamous cell carcinoma (SCC) in 2 patients (3.33%). When the two groups were compared in terms of pathological subtype, there was no significant variation between the two groups. There was also no significant variation between the two groups when compared on the basis of tumor stage (P = 0.36 for T phase, P = 0.122 for N phase), early stage, late phase (P = 0.15), survival rate (P = 0.69 for general survival), recurrence (P = 0.2 for local recurrence, P = 0.37 for regional recurrence) and distant metastasis (P = 0.3). CONCLUSION: There was no significant relationship between the concentration of these cells in the stained specimens and the disease stage, survival rate, recurrence and distant metastasis discovered.

Pencil in the pharynx: Case report of a penetrating foreign body.

Pharyngeal foreign bodies are commonly encountered in otolaryngological practice. However, in certain instances, particularly in cases of penetrating injuries, major vascular damage leads to severe morbidity and mortality. Management of these cases includes airway protection, bleeding control, imaging of major vascular injury, and prophylactic antibiotics. The case of a 2-year-old patient with penetrating pharyngeal foreign body is described in the present report.

Ectopic salivary gland of the base of the tongue: a rare cause of neonatal respiratory distress.

Neonatal upper airway obstruction is a life-threatening condition and requires rapid assessment and effective treatment. Malformations of the upper airway of a newborn can lead to acute respiratory distress. The aim of the present paper is to report the case of a newborn with respiratory distress due to a tongue base mass, which was removed surgically. The patient needed a tracheostomy tube for only three days and then could breathe spontaneously. However, he had swallowing problems, which decreased gradually over 9 months. Histopathologically, the mass was found to consist of mucous salivary glands, and was recorded as an ectopic salivary gland, which is extremely rare among the types of masses that may cause upper airway obstruction in a newborn.
