Auditory Behavior in Adult-Blinded Mice

xlomafota13 shared this article with you from Inoreader Auditory Behavior in Adult-Blinded Mice Via Journal of the Association for Research in Otolaryngology Abstract Cross-modal plasticity occurs when the function of remaining senses is enhanced following deprivation or loss of a sensory modality. Auditory neural responses are enhanced in the auditory cortex, including increased sensitivity and frequency selectivity, following short-term visual deprivation in adult mice (Petrus et al. Neuron 81:664–673, 2014). Whether or not these visual deprivation–induced neural changes translate into improved auditory perception and performance remains unclear. As an initial investigation of the effects of adult visual deprivation on auditory behaviors, CBA/CaJ mice underwent binocular enucleation at 3–4 weeks old and were tested on a battery of learned behavioral tasks, acoustic startle response (ASR), and prepulse inhibition (PPI) tests beginning at least 2 weeks after the enucleation procedure. Auditory brain stem responses (ABRs) were also measured to screen for potential effects of visual deprivation on non-behavioral hearing function. Control and enucleated mice showed similar tone detection sensitivity and frequency discrimination in a conditioned lick suppression test. Both groups showed normal reactivity to sound as measured by ASR in a quiet background. However, when startle-eliciting stimuli were presented in noise, enucleated mice showed decreased ASR amplitude relative to controls. Control and enucleated mice displayed no significant differences in ASR habituation, PPI tests, or ABR thresholds, or wave morphology. Our findings suggest that while adult-onset visual deprivation induces cross-modal plasticity at the synaptic and circuit levels, it does not substantially influence simple auditory behavioral performance.

The music-related quality of life: Italian validation of MuRQoL into MUSQUAV questionnaire and preliminary data from a cohort of postlingually deafened cochlear implant users

xlomafota13 shared this article with you from Inoreader The music-related quality of life: Italian validation of MuRQoL into MUSQUAV questionnaire and preliminary data from a cohort of postlingually deafened cochlear implant users Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2022 Jan 28. doi: 10.1007/s00405-022-07258-1. Online ahead of print. ABSTRACT PURPOSE: Cochlear implant (CI) users do not receive much of the auditory information necessary for an accurate perception of music. This usually entails a dissatisfaction with the music they hear, so that their quality of life may potentially be affected. The main aim of this paper was to translate and validate into Italian an instrument to evaluate these aspects-The Music-Related Quality of Life Questionnaire (MuRQoL)-to help the work of clinicians and therapists. METHODS: The translation of the MuRQoL into "Questionario Musica e Qualità della Vita" (MUSQUAV) was done according to the international guidelines. The translated questionnaire was administered to normal hearing (NH) and CI users adults. Exploratory factor analysis, confirmatory factor analysis and known group method were used to confirm construct validity and app licability of MUSQUAV. RESULTS: We retrieved 225 results. The MUSQUAV questionnaire was acceptable according to the goodness-of-fit indices. The correlation between the items, evaluated using Cronbach's α coefficient, indicates a good internal consistency (> 0.80). The non-parametric Mann-Whitney test showed significant differences in the distinct populations tested. CONCLUSIONS: The MUSQUAV questionnaire is a valid, low-cost and rapid instrument for professional workers in the audiological field, especially useful in the assessment of the patients' perception and musical engagement.

Intraoral Approach for Parapharyngeal Branchial Cleft Cysts

xlomafota13 shared this article with you from Inoreader Intraoral Approach for Parapharyngeal Branchial Cleft Cysts Via ear nose throat Ear Nose Throat J. 2022 Jan 28:1455613211067846. doi: 10.1177/01455613211067846. Online ahead of print. ABSTRACT Branchial cleft cyst (BCC) most frequently arises from the second branchial cleft and is located anterior to the sternocleidomastoid muscle at the mandibular angle. However, very rarely, this may occur in the parapharyngeal space. Interestingly, the parapharyngeal BCC is frequently misdiagnosed as a peritonsillar abscess. In this study, we reported 2 cases of para pharyngeal BCC misdiagnosed as peritonsillar abscess. PMID:35088618 | DOI:10.1177/01455613211067846 View on the web Inoreader.

ABSTRACT Objective: To explore the methods for the accurate resection of malignant tumors of the external nose, and the accurate evaluation and repair of tissue defects. Methods: We collected 48 cases with nasal malignant tumors treated in 980 Hospital, Joint Support Force of the People's Liberation Army from January 2010 to June 2020, including 28 males and 20 females, aged 36-86 years. The pathological types of tumors included basal cell carcinomas (n=29), squamous cell carcinomas (n=11), trichilemmal carcinomas(n=6), denoid cystic carcinoma (n=1) and non-Hodgkin lymphoma (n=1). Tumor resection was mainly based on the traditional extended resection determined by the safety margin, and Mohs surgery was used to minimize the scope of resection, for the margin that significant ly affected the repairing results, such as the lesion adjacent to the nasal alar margin, nasal columella or deep easy-penetrating margin. All cases obtained tumor resection and primary/secondary defect reconstruction. Results: According to the pathological type and tumor size, the safe resection margin was mainly 4-10 mm, and Mohs surgery was used in 24 cases. Limited-size defects in 38 cases were repaired with double-leaf flaps, kite flaps, nasal dorsum brow flaps, nasolabial flaps or free tissues. Among 10 cases with compound defects, 8 cases were repaired with frontal flaps, including 4 cases with single frontal flaps, 2 cases with additional titanium mesh stent reconstruction and 2 cases with over and out frontal flaps. During follow-up of 1 to 10 years, all the flaps survived without flap necrosis, and the postoperative nasal contour and ventilation were satisfactory. One patient had tumor recurrence 18 months after operation, 2 patients died of cardiovascular and cerebr ovascular diseases, and other patients survived without tumors. Conclusions: Mohs surgery can basically meet the requirements for precise resection of external nasal malignant tumors. Individualized application of adjacent tissue flaps and various frontal flaps is a reasonable choice to achieve the satisfactory outcome of external nasal repair and to take into account the complexity of operation.

Evaluation of chemosensory function in patients with upper respiratory tract post-viral olfactory dysfunction

xlomafota13 shared this article with you from Inoreader Evaluation of chemosensory function in patients with upper respiratory tract post-viral olfactory dysfunction Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2022 Jan 7;57(1):29-35. doi: 10.3760/cma.j.cn115330-20210331-00163. ABSTRACT Objective: To observe the changes of olfactory function, intranasal trigeminal nerve function and taste function in patients with upper respiratory tract post-viral olfactory dysfunction (PVOD), and to explore the correlation of chemosensory function. Methods: The clinical data of 42 patients with PVOD who visited to the Olfactory and Taste Center of Otorhinolaryngology Head and Neck Surgery Department of Beijing Anzhen Hospital from January to December of 2019 were analyzed retrospectively, including 20 males and 22 females, aging (48.86±11.47) years (x¯). Twenty subjects in normal control group were selected according to the sex ratio of PVOD patients. Sniffin' Sticks olfactory tests were performed on the subjects, including threshold test (T), discrimination test (D) and identification test (I), and the sum of the above three test scores was the TDI value. At the same time, olfactory event-related potentials (oERPs), trigeminal event-related potentials (tERPs) and taste function test were performed. According to the taste function test, the patients were divided into normal gustation (NG) group and gustatory dysfunction (GD) group. The results of olfaction, taste and intranasal trigeminal nerve function tests were compared among different groups, and the correlation analysis was carried out. SPSS statistical software was used for statistical analysis. Results: GD was present in 14 (33.3%) of 42 PVOD patients with a course of PVOD of 5 (3, 6) months (M (Q1, Q3)). The gustatory function of patients with PVOD was related to gender (r=0.565, P<0.001), smoking status (r=-0.512, P=0.001), duration (r=-0.357, P=0.020) and olfactory function (all P<0.05). The olfactory function of GD group was worse than that of NG group, and the differences of TDI value and T value between the two groups were statistically significant (10.25±4.58 vs 13.35±3.61, 1.54±0.66 vs 2.10±0.88, t value was 2.40 and 2.10 respectively, both P<0.05). The amplitudes of oERPs and tERPs were significantly lower in GD group than those in NG group (all P<0.05). Conclusion: In patients with PVOD, the subjective and objective olfactory function, intranasal trigeminal nerve function and taste function were decreased, and there was a correlation, suggesting that there was a synergistic effect between the chemosensory functions of PVOD patients.

Place of Linacs in extracranial stereotactic radiotherapy: Are they now equivalent to Cyberknife®?

xlomafota13 shared this article with you from Inoreader Place of Linacs in extracranial stereotactic radiotherapy: Are they now equivalent to Cyberknife®? Via Association française pour l'étude du cancer Bull Cancer. 2022 Jan 25:S0007-4551(22)00003-0. doi: 10.1016/j.bulcan.2021.10.008. Online ahead of print. ABSTRACT Extracranial stereotactic radiotherapy has developed recently, since the years 1990-2000. Devices specifically dedicated to this type of treatment were then developed and shared the favors of radiation oncologists: Tomotherapy® and especially Cyberknife®, which offered the advantage of "tracking" with the possibility of real time motion correction, allowing an increase in the precision of targeting volumes. Recently, the latest generations of linear accelerators (Linac) have been developed, integrating much higher dose rates, an improved ballistic precision with a very short treatment duration time and the possibility of real time motion management (with notably the possibility of adaptive radiotherapy in real time with the development of "MLC tracking"). So are Linacs able to perform equivalent (not inferior) extracrani al stereotactic radiotherapy treatments to those with Cyberknife®, the historical gold standard in this field? This article presents a comparison of these two treatment devices, by successively considering dose distributions in the irradiated volume, distant received doses from this volume (including the "integral dose"), problems linked to the duration of the sessions and those linked to motion management.
