Objetivo: Comparar e investigar los parámetros de la tomografía de coherencia óptica (OCT) de los lados sanos y afectados de pacientes con pérdida auditiva neurosensorial súbita idiopática (PANSI). ...Método: La evaluación ocular bilateral de los pacientes diagnosticados con PANSI se realizó con OCT. Se registraron los valores de espesor del complejo de células ganglionares (CCG) y de la capa de fibras nerviosas de la retina (CFNR), y se examinaron las diferencias entre los dos ojos. Resultados: Se evaluaron 39 pacientes, con una edad media de 44.82 ± 14.90 años. Se determinó que el grosor de la CFNR de los ojos era una media de 89.87 ± 3.65 μm en el lado afectado y 103.87 ± 3.98 μm en el lado de control sano (p = 0.0001). Se determinó que el CCG medio era 90.46 ± 3.49 μm en el lado afectado y 103.77 ± 3.96 μm en el lado de control sano (p = 0.0001). Conclusiones: Se encontró una diferencia estadísticamente significativa entre los ojos sanos y afectados de pacientes con PANSI con respecto al CCG medio y al espesor medio de la CFNR. La OCT podría ser una técnica útil para medir esta degeneración neuronal.
Idiopathic sudden sensorineural hearing loss (ISSHL) is a rapid loss of hearing, exceeding 30 dB in at least 3 consecutive frequencies within 3 days, without any identifiable cause despite thorough ...investigations. Currently, the etiology and pathogenesis of ISSHL have not been fully elucidated. This study aimed to assess the size of the cochlear nerve in patients with ISSHL and explore its relationship with pretreatment audiograms and treatment response. Subjects and.
A total of 125 patients (59 47.2% women; mean age 47.7±13.8 years minimum-maximum: 21-76) and 60 healthy participants (27 45% women; mean age 45.7±16.8 years minimum-maximum: 20-76) as a control group were included in this study. The size of the cochlear nerve was assessed on the affected side, compared to the control group, as well as on the unaffected side. Pretreatment and posttreatment audiological values were also analyzed.
The cross-sectional area (CSA), vertical diameter (VD), and horizontal diameter (HD) of the CN were found to be smaller on the affected side of ISSHL patients compared to the control group (p<0.01; p=0.04; p=0.02, respectively). In the study group (affected side of ISSHL patients), there were no significant differences in VD, HD, and CSA values between pretreatment audiogram types (p=0.23; p=0.53; p=0.39, respectively), and initial hearing levels (p=0.16; p=0.22; p=0.23, respectively). Furthermore, there were no significant differences in VD, HD, and CSA values between the recovery groups according to Furuhashi criteria (p=0.18; p=0.37; p=0.27, respectively).
The size of the CN may be a risk factor for ISSHL, but it does not affect the type of audiogram curves and was not prognostic in terms of treatment response.
Introduction:
The gap junction beta 6 (
GJB6
) gene encodes connexin 30. This protein plays critical role in tissues and is responsible for the formation of gap junctions, which have a wide variety ...of physiological functions. Disease-associated variants of
GJB6
cause non-syndromic hearing loss (HL) and skin lesions.
We herein describe a Turkish girl who was diagnosed with HL and in whom genetic analysis revealed a causal variant of
GJB6.
Case presentation:
The 1-year-old girl patient was diagnosed with bilateral HL when she was 1 month old. Apart from this, the patient’s motor/mental development and physical examination were normal. As a result of the analysis with the multi-gene panel, the causative genomic change, c.175G>A(p.Gly59Arg) in the
GJB6
gene was determined as heterozygous. Segregation analysis proved the same genotype in the patient’s mother and grandfather. The patient’s mother and grandfather had bilateral HL and palmoplantar hyperkeratosis phenotype. The patient was diagnosed with Clouston syndrome, and genetic counseling was provided to her family.
Discussion:
Causal variants of
GJB6
cause skin manifestations and signs of HL. Molecular diagnosis of these patients is a valuable tool for clinicians in reaching their optimal treatment and clinical management.
Conclusion:
In syndromic cases in which many organs are affected, the determination of the causative gene is important in directing the patients to appropriate observation, screening, and treatment strategies.
Head and neck cancer (HNC) is one of the most common malignancies in the world. HNC is a group of cancers that starts in the mouth, nose, throat, larynx, sinuses, or salivary glands. According to ...this section of the body parts; induction of cancer can be associated with CO
2
and oxidative stress. The aim of this study is to assess the activities of carbonic anhydrase (CA), catalase (CAT), paraoxonase1 (PON1), and xanthine oxidase (XO) activities in 89 HNC patients and 115 healthy volunteers. Paraoxonase1 activity was found lower in HNC cancer patients. There is no statistically significant difference between patients and controls for catalase, carbonic anhydrase, and xanthine oxidase enzyme levels. According to this results, paraoxonase1 levels could be a candidate as an oxidative marker in HNC patients, but further studies are needed to investigate the other type of cancer related PON1 and the other enzyme levels.

INTRODUCTION: To compare sugammadex and neostigmine regarding the efficacy in reversing rocuronium-induced neuromuscular block, the incidence of post-operative respiratory complications and costs in ...patients undergoing surgery for the treatment of obstructive sleep apnoea (SA). METHODS: After obtaining ethical approval and patient consent, 74 patients in ASA physical status I or II were randomised into two groups to receive 2-mg kg?1 sugammadex (Group S) or 0.04-mg kg?1 neostigmine+0.5-mg atropine (Group N). Groups were compared regarding time to TOF (train-of-four) 0.9, operating room time, post-anaesthesia care unit (PACU) stay, post-operative respiratory complications, costs related to neuromuscular block reversal and follow-up and treatment complications. RESULTS: Patient demographics, anaesthesia, surgical data and total rocuronium doses were similar between groups. Time to TOF 0.9 was shorter for group S Group N: 8 (5-18) min; Group S: 2 (1.5-6) min (p<0.001). Operating room time Group S: 72.4±14.3 min; Group N: 96.6±22.8 min (p<0.001) and PACU stay Group S: 22.9±10.1 dk; Group N: 36.3±12.6 dk (p<0.001) were also shorter in Group S. After extubation, desaturation was observed in 12 (32.4%) patients in group N and in 4 (8%) patients in group S (p=0.048). In group N, three patients were reintubated; there were eight (21.6%) unplanned intensive care unit (ICU) admissions. There was one unplanned ICU admission in group S. Negative pressure pulmonary oedema was observed in one patient in group N. The results regarding costs were as follows: the cost of staff anaesthesia doctor was 0.392 TL per min and the cost of nurse anaesthetist was 0.244 TL per min. The reversal cost was higher in the sugammadex group (vial cost 98.14 TL) than that in the neostigmine group (ampoule cost 0.27 TL; total 6147.88 TL vs. 3569.5 TL); however, the total follow-up and complication treatment cost were lower in group S than those in group N (199.5 TL vs. 3944.6 TL). DISCUSSION AND CONCLUSION: This study confirmed the efficacy of sugammadex over neostigmine for the reversal of rocuronium-induced neuromuscular block. Sugammadex decreases the incidence of post-operative respiratory complications and related costs in patients with SA.
Abstract Objective This study aimed to investigate whether there is a negative impact as a result of psoriatic arthritis disease of the inner ear function. Methods Twenty-four successive patients and ...38 healthy volunteers, younger than 60 years of age, who were followed up for at least for one year in the outpatient clinics of physical therapy and rehabilitation with the diagnosis of PsA according to CASPAR criteria (17) and who did not complain of any hearing impairment were included in the study. Distortion-product otoacoustic emission (DPOAE) values between 1 kHz and 4 kHz, tympanometric examination results, stapes reflex values, speech reception threshold (SRT) and speech discrimination (SD) values, pure-tone values between 250 and 8000 Hz and high-frequency values between 10,000, 12,500 and 16,000 Hz were analyzed. Statistical comparisons between both groups were performed using chi-square test and Mann–Whitney U test. p < 0.05 was accepted as the level of statistical significance. Results Our study population consisted of 24 9 male (37.5%) and 15 female (62.5%) patients with a mean age of 47.21 ± 11.28 (range, 28–59) years and 38 16 male (42.1%) and 22 female (57.9%) healthy volunteers with a mean age of 44.39 ± 8.12 (range, 29–59) years as the control group. Mean duration of arthritis was 7.62 ± 4.88 years. In the evaluation of hearing frequencies of the patients between 4000 and 6000 Hz, a statistically significant difference was found relative to the control group ( p < 005). DPOAE values of the patients were analyzed within the 1000–4000 Hz interval. When compared with the control group, a statistically significant difference was found at 3000 and 4000 Hz ( p < 005). Conclusion Our study provides strong evidence suggesting the necessity of monitorization of these patients regarding sensorineural hearing loss so as to take measures against the development of hearing loss during early stage, which may be another disability in patients with PsA, which is itself a potential cause of severe disability.

Objective: In this work, a new methodology based on signal processing techniques for the quantitative analysis of uvulopalatal flap surgery is proposed. Clinical assessment studies of uvulopalatal ...flap surgery are based on not only the physician’s examination, but also the patient’s subjective feedback. Quantitative and objective evaluation studies are still lacking in the literature.
Materials and Methods: Full night sleep records were analyzed for 21 patients before and after the surgery. The proposed algorithm consists of two independent parts. In the first part, the heart rate variability and complexity of the electrocardiogram were calculated. The second part includes calculating the electroencephalogram sub-band energy. Afterwards, the statistical methods were applied in order to determine the correlation of clinical and experimental parameters.
Results: The low frequency/high frequency ratio and the sub-band energy of beta wave were significant for the patients having low post-operative delta sleep duration. Moreover, the sub-band energies of both alpha and beta waves, and theta wave were significant for the patients who had high post-operative delta sleep duration and blood oxygen saturation (SaO2)-parameter. Complexity was significant for the patients with low postoperative respiratory disturbance index and SaO2 parameter, and respiratory disturbance is correlated with snoring index.
Conclusion: Respiratory disturbance index, which is not significant according to the pre- and post-operative clinical findings, was found to be directly related to the complexity feature. The most important result of this work is that the pre-operative complexity feature is correlated with respiratory disturbance and snoring index. This means that complexity feature can be a predictor prior to surgery.

Background. Parapharyngeal space is one of potential facial planes for neoplasms and infections and represents less than 1% of all head and neck tumours. Occurrence of the pleomorphic adenoma in the ...parapharyngeal space is a rarity. Case Presentation. Here, three giant pleomorphic adenomas of different sizes occupying the parapharyngeal space in three patients are reported. Extensive preoperative diagnostic workup was done in order to verify the nature and size of the tumour and the proximity to the large vessels. Review of the literature, clinical features, pathology, radiological findings, and treatment of these tumours are discussed. Conclusion. The excision of the tumor through submandibular transcervical approach, without cutting the mandible, turned out to be a safe and radical approach in all three cases.
