    ABSTRACT: Conclusions: Cochlear implantation in the poorer ear of an elderly patient does not predict poorer post-operative audiological, quality-of-life (QoL), and quality of sound results. Objectives: To determine whether choosing the better or the poorer ear for cochlear implantation impacts performance outcome in an elderly population. Methods: Forty-two out of 73 elderly (≥ 60 years) cochlear implant users with some residual hearing in at least one ear were selected. Three criteria were used to group the patients as better or poorer ear implanted; (C1) based on previous use of hearing aid, (C2) pre-operative PTA, and (C3) pre-operative speech discrimination. The Glasgow Benefit Inventory (GBI) and the Hearing Implant Sound Quality Index (HISQUI) were used to measure QoL and quality of sound, respectively. Results: The mean post-operative PTA was 38.7 ± 7.2 dBHL. In quiet, the mean disyllabic SDS at 65dBSPL was 75.4 ± 18.5, whereas the discrimination of sentences was 95.0% ± 6.9. The mean total GBI score was 30.9 ± 21.8, 92.9% of patients reporting a positive score. The mean HISQUI score was 111.3 ± 36.0, which corresponds to moderate sound quality. No significant differences were found between both groups in terms of audiological outcomes, HISQUI scores or GBI scores when considering each of the three criteria.

    ABSTRACT: Conclusion: Upper airway surgery is associated with salutary effects on the blood coagulation characteristics of OSA patients, a benefit that may be protective against cardiac and cerebrovascular morbidity and mortality. Objective: Increased blood coagulation is an important factor linking OSA and cardiovascular complications. Surgery is an important method to treat OSA, but the effect of surgery on blood coagulation in OSA patients is unknown. Methods: the authors performed a prospective clinical trial of adult OSA patients who underwent surgery from 2012-2014. Pre-operative and post-operative blood coagulation parameters and polysomnography (PSG) results were compared. Result: There were 61 subjects. The total rate of success in curing OSA was 11.5%. The rate of response after surgery was 40.8%. Overall, the Apnea-Hypopnea Index (AHI) improved after surgery (from 39.8 3 ± 24.49 to 25.9 7 ± 18.53, p < 0.01). After surgery, serum platelet counts (PLT) decreased (from 242.5 ± 52.6 to 230.9 ± 40.7, p=0.01), and Fibrinogen (FIB) levels declined (from 262.5 ± 52.5 to 247.3 ± 44.4, p = 0.02). Other blood coagulation parameters also improved: prothrombin time (PT) (from 10.6 2 ± 0.62 to 10.8 6 ± 0.70, p=0.01), activated partial thromboplastin time (APTT) (from 26.9 8 ± 4.94 to 27.7 8 ± 3.02, p = 0.06), and Thrombin time (TT) (from 19.5 3 ± 0.84 to 20.1 1 ± 1.31, p < 0.01).

    ABSTRACT: Conclusion: HDAC1 may be a prognostic biomarker for LSCC malignant potency and a potent factor resulting in decreased sensitivity of LSCC in radiotherapy. Objective: The aim of this study was to evaluate the correlation between histone deacetylase 1 (HDAC1) over-expression and clinical features in laryngeal squamous cell carcinoma (LSCC). Methods: This study assessed the HDAC1 expressions in 90 formalin-fixed paraffin-embedded LSCC samples, 30 adjacent non-neoplastic tissues, and 30 laryngeal polyp tissues by immunohistochemistry (IHC). In addition, another 40 LSCC samples were collected that were divided into two groups after 3-month radiotherapy: the high radio-sensitive group (HRS) and low radio-sensitive group (LRS). Overall survival curves of all the LSCC patients were constructed by Kaplan-Meier method and long-rank test. Results: All ninety samples were positively immunostained for HDAC1. The expression of HDAC1 was up-regulated and significantly associated with T classification, lymph node metastases, tumor location and clinical stage. HDAC1 was mainly labeled in the epithelial cells of laryngeal polyp tissues and adjacent non-neoplastic tissues. In addition, the expression of HDAC1 was significantly higher in LRS than that in HRS. The positive rates for stage III-IV tumor were significantly higher than those for stage II. LSCC patients with HDAC1 over-expression and LRS presented a shorter 5-year overall survival rate.

    ABSTRACT: Conclusions: Pre-operative planning for parapharyngeal tumors must include meticulous analysis. Factors such as tumor size, distance to cranial base, and relation to neurovascular structures must guide the selection of a surgical approach. Objective: To summarize experience in diagnosis and surgical management of parapharyngeal tumors, analyzing the frequencies of various tumoral types, clinical presentation, choice of surgical approach and outcomes. This study also compares the results with the most relevant case series in the literature. Methods: A retrospective review was performed of the records of 51 patients treated by the team, from 1984-2012. Only primary tumors were included, excluding invasion from adjacent spaces and metastatic disease. All patients underwent imaging studies and surgical resection of the neoplasm. Cytological analysis and arteriography were used on an individualized basis. Surgical excision was performed via different approaches, predominantly through a cervicoparotid route. Results: Benign neoplasms were predominant (80%), and the most frequent tumor was pleomorphic adenoma. FNAC had a 100% accuracy to differentiate benign vs malignant tumors. The most common post-operative sequel was compromise of a cranial nerve, and three patients presented local complications after surgery. After follow-up, only three of 41 patients with benign tumors had recurring disease.

    ABSTRACT: Conclusion MRI examinations in patients with an alternatively coupled VSB can lead to unpleasant side-effects. However, the residual hearing was not impaired, whereas the hearing performance with the VSB was decreased in one patient which could be fixed by a surgical revision. Different experiences for the VSB 503 can be expected. Objective To investigate the in vivo effects of MRI scanning on the Vibrant Soundbridge system (VSB) with an alternatively coupled Floating Mass Transducer (FMT). Method Sixty-five VSB (502) implantees were included in this study. Of them, 42 questionnaires could be evaluated with the patients’ statements about their medical, otological, and general condition before, during, and after an MRI scan which was indicated for different medical reasons, despite the previous implantation of an alternatively coupled Vibrant Soundbridge System. Results In four patients (9.5%), five MRI examinations were performed. These were done for different indications (e.g. knee and shoulder joint diagnostics). During the scanning, noise and subjectively perceived distortion of the implant were described. A deterioration of the hearing gain with the VSB in place was found in one patient. A decrease of the hearing threshold was not observed

    ABSTRACT: Conclusion: Gastrostomy tube replacement using a new approach through the abdominal-wall stoma with a small-caliber trans-nasal endoscope is feasible, fast, and safe compared with the trans-oral approach. Objectives: To evaluate the feasibility of a new technique using a trans-nasal endoscope for gastrostomy tube replacement. Methods: Between June 2005 and December 2013 in the Peking University Third Hospital, 69 patients underwent gastrostomy tube replacement using the trans-oral approach (conventional method) or a small-caliber trans-nasal endoscope inserted through the abdominal-wall stoma (new method). A retrospective review was performed of the medical records of those patients, including demography and information about the surgical procedure and any complications. Patients were classified into the conventional group and the new method group. Descriptive statistics for all continuous variables were mean ± standard deviation and for categorical variables were number and percentage. Results: Gastrostomy tube replacement was achieved in 69 of 69 cases (100%); 23 of these procedures were performed using the new method. The surgery time with the conventional method (8.3 ± 2.0 min) was significantly longer than with the new method (6.0 ± 0.9 min, p < 0.001). With the conventional method, there was one patient (2%) with post-operative fever and skin infection; no complications occurred with the new method.

    ABSTRACT: Conclusion: The prevalence of low-tone hearing loss (LTHL) is significantly high in spinocerebellar degeneration (SCD) with cerebellar predominance, including multiple-system atrophy C (MSA-C) and cortical cerebellar atrophy (CCA). Objective: This study aimed to test the hypothesis that SCD with cerebellar predominance, MSA-C and CCA may cause auditory symptoms. Methods: The shape and threshold of pure-tone audiograms were evaluated for MSA-C (n = 47; mean (± SD) age, 61.6 ± 8.9 years), CCA (n = 16; 62.8 ± 9.5 years), and age-matched controls (n = 169; 62.5 ± 10.7 years). To differentiate specific hearing loss for MSA-C and CCA from presbycusis, the shape of audiograms was examined based on previously established audiological criteria. Results: When audiogram shape was defined according to audiological criteria, the odds ratio for LTHL in SCD compared to controls was 2.492 (95% confidence interval (CI) = 1.208-5.139; p < 0.05, Pearson's Chi-square test) in MSA-C and 2.194 (95% CI = 0.709-6.795) in CCA. When the selection of audiogram shape according to these criteria was verified by three certified audiologists, odds ratios for LTHL in MSA-C and CCA were 3.243 (95% CI = 1.320-7.969) and 3.692 (95% CI = 1.052-12.957), respectively, significantly higher than in controls.

    ABSTRACT: Conclusion: The average SNOT 22 score should be calculated locally and be used as a reference when managing patients with nasal symptoms. Objective: To calculate the average Sino Nasal Outcome Test (SNOT) 22 score across Lanarkshire and to compare it with similar studies. Methodology: Prospective data collection in which SNOT 22 forms were filled by the Lanarkshire population who had no history of sinonasal disease. Participants included patient attendants and hospital staff across multiple hospital sites in NHS Lanarkshire. All patients with hay fever, previous nasal surgeries, or any history of use of topical steroid sprays were excluded from the study. Results: This study included 118 participants, out of which three had to be excluded due to unclear data entry. The total number for SNOT forms included for analysis was 115. This included 85 females and 29 males, while one form remained unanswered. The mean age was 49 (range = 15-81) years. The mean SNOT 22 score was 18 (range = 0-89).

    ABSTRACT: Conclusion: Contrast-enhanced magnetic resonance imaging (MRI) reveals variations in the endolymphatic morphology of the cystic lateral semicircular canal (CLSC) that correlate with inner ear function. This report is the first to suggest a relationship between the morphology and function of this common inner ear malformation in clinical cases. Objectives: This study investigated the radiological and functional findings of a common inner ear malformation using computed tomography (CT), gadolinium contrast-enhanced magnetic resonance imaging (MRI), caloric testing, and cervical and ocular vestibular evoked myogenic potential (VEMP) testing. Method: Four ears in three patients who were radiologically diagnosed with a CLSC and a normal cochlea on high-resolution CT and contrast-enhanced MRI were included. Semicircular canal and vestibular functions were analyzed using the caloric test and cervical and ocular VEMP testing. Results: Unilateral and bilateral cystic canals were found in two and one patients, respectively. In the first patient, the malformed vestibule and cystic space were separate on imaging, and perilymph filled the cystic space. The functional test results were normal. In the second patient, endolymph filled both cystic spaces, and the functional responses were poor. In the third patient, endolymph filled the cystic space, and the ear did not respond during functional testing.

    ABSTRACT: Conclusions: Postural control is dependent on the visual system in normal conditions. Shift from visual to somatosensory dependence in dizzy patients suggests that utilizing the stable visual references is recommended for the rehabilitation of dizzy patients. Objectives: To investigate which of the visual or somatosensory system is mainly used for substitution of the impaired spatial orientation in dizzy patients. Methods: We recruited 189 consecutive patients with or without dizziness and vestibular dysfunction. Dizzy patients were divided into three groups: acute, episodic, and chronic dizziness. Vestibular function was assessed by caloric test, traditional head impulse test, and head shaking nystagmus. Visual or somatosensory dependence of spatial orientation was assessed by posturography on a solid surface or on foam in eyes open or closed condition. The foam ratio (posturography with/without foam) when eyes were closed was indicative of somatosensory dependence of postural control, whereas the Romberg ratio on foam showed visual dependence. (Romberg ratio on foam)/(foam ratio with eyes closed) was calculated and used as an index of the visual/somatosensory dependence of postural control. Results: The visual/somatosensory ratio of postural control was significantly lower in dizzy patients as well as patients with vestibular dysfunction, however, no differences were found between acute, episodic, and chronic dizziness.

    ABSTRACT: Programmed cell death (PCD) initially starts in the support cells (SCs) after electrode insertion trauma (EIT), followed by PCD in hair cells (HCs). Activation of caspase-3 was observed only in SCs. Protecting both SCs and HCs with selective otoprotective drugs at an early stage post implantation may help to preserve residual hearing. Cochlear implant EIT can initiate sensory cell losses via necrosis and PCD within the organ of Corti, which can lead to a loss of residual hearing. PCD appears to be a major factor in HC loss post-EIT. The current study aimed to: (1) determine the onset of PCD in both SCs and HCs within the traumatized organ of Corti; and (2) identify the molecular mechanisms active within the HCs and SCs that are undergoing PCD. Adult guinea pigs were assigned to one of two groups: (1) EIT and (2) unoperated contralateral ears as controls. Immunostaining of dissected organ of Corti surface preparations for phosphorylated-Jun, cleaved caspase-3, and 4-hydroxy-2,3-nonenal (HNE) were performed at 6, 12, and 24 h post-EIT and for contralateral control ears. At 6 h post-EIT the SCs immunolabeled for the presence of phosphorylated-Jun and activated caspase-3. Phosphorylated p-Jun labeling was observed at 12 h in both the HCs and SCs of middle and basal cochlear turns. Cleaved caspase-3 was not observed in HCs of any cochlear turn at up to 24 h post-EIT. Lipid peroxidation (HNE immunostaining) was first observed at 12 h post-EIT in both the HCs and SCs of the basal turn, and reached the apical turn by 24 h post-EIT.
