RESUMEN

BACKGROUND: The impacts of coronavirus disease-2019 (COVID-19) on nasal mucociliary clearance (MCC) have shown conflicting results. OBJECTIVES: The aim of this study was to determine whether COVID-19 infections affect nasal mucociliary activity using the saccharin test to measure nasal MCC time. MATERIAL AND METHODS: This prospective comparative investigation included 25 patients with COVID-19 infection and 25 healthy controls. The nasal MCC time was assessed using the saccharin test. Saccharin test was applied to COVID-19 patients between the 10th and 20th days of COVID-19 test positivity. Patients admitted to the otolaryngology outpatient clinic with non-nasal symptoms and no history of COVID-19 infection served as the control subjects. RESULTS: Age, gender distribution, smoking, and alcohol usage, and the existence of other systemic disorders had no statistically significant differences between the groups (p = 0.25, p = 0.77, p = 1.00, p = 0.28, p = 0.54, respectively). The COVID-19 group had a mean nasal MCC time of 12.00 ± 2.51 min, compared to 9.77 ± 2.51 min in the control group. The nasal MCC time in the COVID-19 group was statistically significantly longer (p = 0.043). CONCLUSIONS AND SIGNIFICANCE: The COVID-19 infection negatively affects mucociliary activity and causes prolongation of MCC. As the nasal defense mechanism weakens in the early period after COVID-19 infection, susceptibility to respiratory infections may occur.

RESUMEN

Objective: To investigate the effects of dizziness on sleep quality and psychological status in patients with benign paroxysmal positional vertigo (BPPV) and to evaluate its relationship with falls. Methods: A Demographic Data Form, a Visual Vertigo Analog Scale, the Falls Efficacy Scale - International (FES-I), the Hospital Anxiety and Depression Scale (HADS), and the Pittsburgh Sleep Quality Index (PSQI) were administered in 102 individuals diagnosed with BPPV by videonystagmography test. The same scales were applied to 75 healthy volunteers as the control group, and the two groups were compared. The BPPV group was divided into two groups as posterior canal and lateral canal BPPV. These two groups were compared among themselves and with the control group. Results: A statistically significant difference was found between the BPPV and control groups, the lateral canal BPPV and posterior canal BPPV groups, the lateral canal BPPV and control groups, and the posterior canal BPPV and control groups in terms of total scores of the PSQI, the FES-I, and the HADS (p<0.001). In the regression model, the FES-I score was fully explained by the PSQI and HADS scores (p<0.001). Conclusion: BPPV significantly affects sleep quality, psychological state, and the risk of fall. The negative effects of BPPV restrict daily living activities, affect the prognosis of the disease, and increase the risk of falling. Considering that psychiatric issues and sleep problems increase the risk of falling in individuals with BPPV, counseling services on this issue would reduce the incidence of falls and related injuries.

RESUMEN

ABSTRACT: Nasal chondromesenchymal hamartoma is a rare benign tumor of the sinonasal tract in pediatrics and only few cases in infantile, early pediatric, and adolescent population have been reported. Nasal chondromesenchymal hamartoma commonly presents as respiratory difficulty, intranasal mass, or facial swelling and typically arises from the nasal septum or vestibule, lest frequently maxillary or ethmoid sinuses, orbit, nasopharynx, and oropharynx. The authors report a case of nasal chondromesench- ymal hamartoma that caused respiratory distress since birth, in a 4- week-old (28 days) infant which was arised from the medial aspect of the middle turbinate, an unexpected localization.

RESUMEN

PURPOSE: It was aimed to investigate the effects of COVID-19 infection on hearing and the vestibular system. METHODS: Twenty-six patients whose treatment had been completed and who had no previous hearing or balance complaints were included in the study. Patients diagnosed with the disease by PCR were included in the study. Patients with at least one month of illness were included in the study. The hearing of patients was evaluated with transient evoked otoacoustic emissions (TEOAE) and pure-tone audiometry. Bedside tests, the European Evaluation of Vertigo scale (EEV), Video Head Impulse Test (vHIT), Ocular Vestibular Myogenic Evoked Potential (oVEMP), Cervical Vestibular Myogenic Evoked Potential (cVEMP) and Videonystagmography (VNG) tests were applied to evaluate the vestibular system. RESULTS: A statistically significant difference was found between the COVID-19 positive and control groups according to the mean values of the 4000 Hz and 8000 Hz in both the right and left ears (p < 0.05). No statistically significant difference was found in the other frequencies and TEOAE. No statistically significant difference was found between the COVID-19 positive and control groups in terms of their normal or pathological VNG saccade, optokinetic and spontaneous nystagmus values (p > 0.05). The normal and pathological VNG head shake values were found to be significantly different between the COVID-19 positive and control groups (p < 0.05). CONCLUSiON: The high frequencies in audiometry in the COVID-19 positive group were worse than those in the control group. In the vestibular system, especially in oVEMP and cVEMP, asymmetric findings were obtained in comparison to the control group, and a low gain in vHIT was shown. This study shows that the audiovestibular system of people with COVID-19 infection may be affected.

RESUMEN

OBJECT: To prepare a national guideline for Otorhinolaryngologist who treat allergic rhinitis patients. METHODS: The study was conducted by three authors, namely the writing support team. The support team made the study plan, determined the writing instructions, chose the subgroups including the advisory committee, the advisors for authors and the authors. A workshop was organized at the very beginning to explain the details of the study to the team. Advisors took the chance to meet their coworkers in their subgroups and determined the main headings and subheadings of the guideline, together with the authors. After key words were determined by the authors, literature search was done in various databases. The authors keep in touch with the advisors and the advisors with the advisory committee and the support group at every stage of the study. National and International published articles as well as the abstracts of unpublished studies, imperatively presented in National Congresses, were included in this guideline. Only Guideline and meta-analyses published in last seven years (2013-2017) and randomized controlled studies published in last two years (2015-2017) were included. After all work was completed by the subgroups, support team brought all work together and edited the article. RESULTS: A detailed guideline about all aspects of allergic rhinitis was created. CONCLUSION: The authors believe that this guideline will enable a compact and up-to-date information on allergic rhinitis to healthcare professionals. This guideline is the first in the field of Otolaryngology in Turkey. It should be updated at regular intervals.

RESUMEN

BACKGROUND: Deformity in the dental arc and facial skeleton by adenoid hypertrophy due to chronic mouth breathing is a well-known process. Most of the related studies have been based on cephalometric analyses. The aim of this study is to detect the presence of skeletal deformities on the soft tissue by analyzing distances and angles on photographs. METHODS: Ninety-seven children having between 25 and 100 % of adenoids, ages 4-12 years (48 boys, 49 girls), and 90 cases having 0-25 % adenoid tissue, ages 4-12 years (54 boys, 36 girls), were studied by clinical history, physical examination (including endoscopy), and standardized clinical photographs. The children and parents were asked if any of the following were present in the children: snoring, sleep apnea, daytime sleepiness, poor school performance, mouth breathing during sleep, smoking parents, and restlessness during sleep. RESULTS: The assessment of linear and angular measurements on the clinical photographs showed, in the group having thicker adenoids compared with controls, a statistically significant increase in the distance between nasion and tip and nasion and subnasale and in the angle between Frankfort horizontal plane-gnathion-angulus mandible; there was also a statistically significant decrease in the distance between endocanthion and exocanthion and the angles between tragion-angulus mandible and gnathion and between nasion-angulus mandible and gnathion. CONCLUSIONS: The analyses showed a significant increase in the anterior face height and increase in the angle between Frankfort horizontal plane-gnathion-angulus mandible and a retropositioned and posterior-rotated mandible due to thicker adenoids. TRIAL REGISTRATION: 2010/140 Date: 04 January 2010.

RESUMEN

INTRODUCTION: There is an ongoing debate about the existence and effects of Helicobacter pylori (Hp) in adenotonsillar tissue. OBJECTIVE: A clinical study was conducted to assess the existence of Hp in the adenoid and/or adenotonsillar tissues, which were surgically excised due to chronic adenotonsillitis. METHODS: Phosphoglucosamine mutase gene for the detection of Hp and cytotoxin-associated gene as virulence gene were examined in 84 adenotonsillar tissues obtained from 64 patients and patients' serum by using polymerase chain reaction. RESULTS: Hp IgG was detected in 57 (89%) patients' serum. A total of seven tissue samples from 64 patients (10.9%) were found positive for Hp DNA, of which five were adenoids and two were tonsil tissues. All polymerase chain reaction positive samples were also positive for the cytotoxin-associated gene, which is a virulence determinant for the organism. CONCLUSION: This study suggests that children are exposed to Hp at an early age of their life in this province. Hp may have a role in the pathogenesis of chronic adenotonsillitis, especially in endemic areas. .


INTRODUÇÃO: Há um debate atual sobre os efeitos da Helicobacter pylori (HpHp) no tecido adenotonsilar. OBJETIVO: Conduzimos um estudo clinico para avaliar a existência de Hp nos tecidos adenoideano e/ou adenotonsilar, os quais foram removidos cirurgicamente em decorrência de adenotonsilite crônica. MÉTODO: No total, 84 amostras de tecido obtidos de 64 pacientes foram analisadas para o gen fosfoglucosamina mutase para a detecção de Hp. Os casos positivos foram a seguir examinados para o gen associado à citotoxina, relacionado à virulência, usando-se o método de Reação de Polimerase em Cadeia (PCR). RESULTADOS: A IgG de Hp foi detectado em 57 (89%) soros de pacientes. Sete amostras de tecido de sessenta e quatro pacientes (10.9%) resultou positivo para o DNA de Hp, das quais cinco eram adenóides e duas eram tecido tonsilar. No PCR todas as amostras foram também positivas para o gen associado à citotoxina, o qual é um determinante de virulência. CONCLUSÃO: Esse estudo sugere que as crianças são expostas ao Hp nos primeiros anos de vida nessa província e que o Hp pode ter um papel na patogênese da adenotonsilite crônica, principalmente em áreas endêmicas. .

RESUMEN

INTRODUCTION: There is no consensus on duration of the nasal splint after nasal septum surgeries. The pressure of nasal splint on the mucosa may cause tissue necrosis and nasal septum perforation. OBJECTIVES: To investigate the histopathological changes of the nasal mucosa caused by nasal splints in a rabbit model. METHODS: No splint was used in group A. Bilateral silicone nasal splints were placed for five, ten, and 15 days in groups B, C, and D, respectively. Biopsy of the nasal mucosa was performed after removal of splint. Histopathologic evaluations were performed. The severity and depth of the inflammation were scored. RESULTS: Group A had a normal histological appearance. Comparison of the results of groups B, C, and D with group A demonstrated statistically significant differences with regards to the severity of histopathological findings. There was no statistically significant difference between groups B and C. There were statistically significant differences between the groups B and D, and also between groups C and D. CONCLUSIONS: Longer duration of nasal splint had a higher risk for septal perforation. Therefore, removal of the splint as soon as possible may be helpful for preventing potential perforations. .


INTRODUÇÃO: Não existe consenso acerca do tempo de permanência de splints nasais no pós-operatório de cirurgias no septo. A pressão causada pelos mesmos na mucosa nasal pode causar necrose e perfurações septais. OBJETIVOS: Investigar mudanças histopatológicas da mucosa nasal causadas por splints nasais em coelhos. MÉTODO: Nenhum splint foi utilizado no grupo A. Splints de silicone foram utilizados por 5, 10 e 15 dias nos grupos B, C e D, respectivamente. Biópsia da mucosa nasal foi realizada após a remoção dos mesmos. Avaliações histopatológicas foram realizadas, e a gravidade e a profundidade do processo inflamatório foram medidas. RESULTADOS: Grupo A apresentou uma aparência histológica normal. Comparações de resultados entre os grupos B, C e D com o grupo A demonstraram diferenças estatísticas relevantes na gravidade histopatológica. Não houve diferenças estatísticas relevantes entre os grupos B e D, assim como entre os grupos C e D. CONCLUSÃO: De acordo com os resultados, quanto maior a duração no uso de splints nasais maior o risco de perfuração septal. Portanto, a remoção de splints nasais deve ser realizada assim que possível, prevenindo potenciais perfurações. .

RESUMEN

This study was undertaken to investigate the effect of betaglucan in ameliorating cisplatin ototoxicity. Rats were divided into four groups: cisplatin (C), cisplatin plus beta glucan (CB), beta glucan (B), and control (K). Distortion product otoacoustic emissions were elicited in 0th, 1st, and 5th days. For the group C differences were observed at 8,003 and 9,515 Hz between 0th and 5th days' measurements. In the group CB there were differences at frequencies of 3,996, 4,757, 5,660, and 6,726 Hz between 0th and 5th days' measurements. For the group B there were significant recovery in some frequencies. The observation of significant deterioration in terms of hearing in the group treated with cisplatin plus betaglucan may be suggested that depended on the increase of permeability and tissue conductance into the inner ear which may be caused by betaglucan. Further long-term follow-up studies by using different doses may clarify this matter.

RESUMEN

IMPORTANCE: It is important that chronic otitis media with cholesteatoma be treated successfully in patients to protect them from having repeated surgeries with related surgical co-morbidities and hearing loss. OBJECTIVE: To evaluate the effectiveness of MESNA usage on the residual cholesteatoma rates of the patients who underwent surgery due to chronic otitis media with cholesteatoma. DESIGN: Retrospective single-institution study of a prospectively collected database. SETTING: Tertiary University Hospital. PARTICIPANTS: Nine hundred and thirty-four patients underwent surgery due to chronic otitis media between September 2000 and March 2012 by the same surgeon. One hundred and forty-one cases out of 934 patients were selected who had cholesteatoma for the study. These randomly selected 141 cases were divided into two groups as follows: I. Forty-six cases were applied MESNA (Sodium 2-mercaptoethanesulfonate) intraoperatively, and II. Ninety-five cases were not applied MESNA intraoperatively. The cases that were followed-up at least one year were included in this study. INTERVENTION: MESNA (Ureomitexan, MESNA, Baxter oncology, Germany) was diluted with saline (20% MESNA and 80% saline) that was applied, and then a waiting period of approximately 5 min followed to start to dissect cholesteatoma matrix. MAIN OUTCOMES AND MEASURES: Residual cholesteatoma rates between intraoperative MESNA, a disulfide bond breaking chemical agent, applied and MESNA non-applied cases in the postoperative follow-up period were compared for the success of the surgery. RESULTS: MESNA was used in 46 patients out of 141 cases intraoperatively. Twenty-four of these patients underwent CWD (canal wall down), and twenty-two patients underwent CWU (canal wall up) mastoidectomy. For the other 95 subjects, 56 patients with CWD and 39 with CWU mastoidectomy, MESNA was not applied. Residual cholesteatoma rates were found to be significantly higher in MESNA non-applied group than MESNA applied group (p<0.05). Residual cholesteatoma rates between CWD and CWU mastoidectomy procedures were not statistically significant (p>0.05). CONCLUSIONS AND RELEVANCE: MESNA application that breaks disulfide bonds in the structure of the matrix in cholesteatoma surgery may assist the elimination of the disease, and increase surgical success by facilitating the elevation of the epithelium. Thereby, it causes a decrease in the possibility of remaining residual epithelium after surgery, which decreases the need for second-look surgery. TRIAL REGISTRATION: The retrospective research protocol was approved by the Inonu University Clinical Research Ethics Committee. REGISTRATION NUMBER: ………

RESUMEN

UNLABELLED: Background/aim: To determine the efficacy of lycopene, which is considered an antioxidant agent, in decreasing the cochlear damage induced by cisplatin. MATERIALS AND METHODS: A total of 38 rats were randomized into 4 groups: control, cisplatin, cisplatin + lycopene, and lycopene-treated groups. In all groups, the distortion-product otoacoustic emission measurements were performed on days 0, 1, 2, and 5. RESULTS: There were no significant differences between the control and lycopene groups at any frequencies. In the cisplatin group, the statistically significant differences were found in the measurements taken between day 0 and day 5 at all frequencies and between days 1 and 5 and days 2 and 5 at some frequencies (P < 0.05). In the cisplatin + lycopene group, a statistically significant difference was found at some frequencies between the measurements taken on days 0 and 5, days 1 and 5, and days 2 and 5 (P < 0.05). Contrary to the results found in the cisplatin group, hearing ability in the lycopene-treated group was observed as being preserved at low frequencies in the measurements taken on days 0 and 5 and days 2 and 5. CONCLUSION: The data of this study suggest that lycopene can prevent the development of ototoxicity induced by cisplatin, especially at low frequencies. Studies on this issue with longer durations and different dose ranges may contribute to the identification of potentially prophylactic effects of lycopene against cisplatin ototoxicity at higher frequencies, as well.

RESUMEN

Facial nerve (FN) macrodehiscence, in contrast to microdehiscence, generally occurs as a result of chronic otitis media and is rarely seen congenitally. A patient with normal hearing who had no history of ear disease or ear operation came to the clinic with recurrent facial paralysis (FP) and frequent blockage of the external ear canal with epithelial debris complaints. In the explorative ear surgery, we observed that the posterior wall of the external ear canal or tympanic ring was absent, a large external ear cavity was covered with a thin skin, the FN was under the skin, and the tympanic-mastoid segment of the FN and chorda tympani extending to the stylomastoid foramen was completely open. FP episodes were associated with the unprotected FN.To prevent an attack of FP, and to self-clean the external ears, mastoid obliteration surgery was performed, and the mastoid segment of the FN was covered with a conchal cartilage graft. This case was diagnosed as congenital aplasia of the external ear canal due to the tympanic bone aplasia-mastoid bone hypoplasia, and the dehiscence of the mastoid-tympanic segment of the FN, and as a cause of recurrent FP, has never to date been identified.

RESUMEN

Inflammatory myofibroblastic tumor is composed of myofibroblast and inflammatory cell infiltration of the tissue. Malign transformation and recurrence rate of this tumor is rare and accepted as benign fibroinflammatory disease. The main etiology is unclear, but infection, trauma, and immunologic event are accused. In this study, we presented a 75-year-old man with a mass on his tongue, which was diagnosed as "inflammatory myofibroblastic tumor." This type of tumor is rarely seen in the tongue and might be difficult to diagnose. Complete mass excision was provided for an adaquete treatment.

RESUMEN

OBJECTIVES: This experimental study investigated the possible protective effect of beta glucans on amikacin ototoxicity. METHODS: Thirty-eight rats with normal distortion product otoacoustic emissions (DPOAEs) were divided into four groups. Group K was the control group. Group A was injected intramuscularly (i.m.) with amikacin 600 mg/kg/day between days 1-15. Group AB was given beta glucan gavage 1 mg/kg/day on days 0-15 and given amikacin 600 mg/kg/day i.m. on days 1-15. Group B was administered only beta glucan gavage, 1 mg/kg/day, on days 0-15. The DPOAEs were elicited in different frequency regions between 2,003 and 9,515 Hz, as distortion product diagrams (DPgrams), before and after the medication was administered, in all groups, on days 1, 5, 10, and 15. RESULTS: No significant changes in the DPgrams were observed in group K. In group A, significant deterioration was observed at the 8,003 and 9,515 Hz frequencies on day 10, and at the 3,991, 4,557, 5,660, 6,726, 8,003, and 9,515 Hz frequencies on day 15. For group AB, statistically significant deterioration was observed at the 2,824, 8,003, and 9,515 Hz frequencies on day 15. The results for group B showed a significant improvement of hearing at the 2,378, 2,824, 3,363, and 3,991 Hz frequencies on day 1, at the 3,363, 3,991, and 8,003 Hz frequencies on day 10, and at the 8,003 Hz frequency on day 15. CONCLUSION: This study suggests that amikacin-induced hearing loss in rats may be limited to some extent by concomitant use of beta glucan.
