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.

xlomafota13 shared this article with you from Inoreader Mucosal melanocytic lesion in the middle ear extending to the inner ear and nasopharynx Via ear nose throat Ear Nose Throat J. 2022 Jan 28:1455613211068571. doi: 10.1177/01455613211068571. Online ahead of print. ABSTRACT Benign dendritic melanocytic proliferation is usually observed in the skin. We report an extremely rare case of a melanocytic lesion in the middle ear mucosa. Only 3 cases of melanocytic lesions in the middle ear have been reported. Our report is the only one that describes an adult with a melanocytic lesion in the middle ear that extended to the inner ear and nas opharyngeal mucosa. A 23-year-old female presented with profound sensory neural hearing loss and recurrent discharge from the right ear. Examination revealed a blue right tympanic membrane with a small perforation. Computed tomography scans and magnetic resonance imaging were performed. After surgical exploration and histopathological examination, the patient was found to have a benign melanocytic lesion in the right middle ear. Melanocytic lesions are commonly found in the skin. There are no previous reports have described adult patients with melanocytic lesions in the middle ear that extend to the inner ear and nasopharynx, which cause profound hearing loss with recurrent ear discharge. These patients require regular follow-up to assess the progression of the lesion and to watch for any malignant behavior. PMID:35088612 | DOI:10.1177/01455613211068571 View on the web Inoreader.

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.

xlomafota13 shared this article with you from Inoreader A new classification of maxillary defect and simultaneous accurate reconstruction 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):8-14. doi: 10.3760/cma.j.cn115330-20210724-00484. ABSTRACT Objective: To select the preferred flaps for the reconstruction of different maxillary defects and to propose a new classification of maxillary defects. Methods: A total of 219 patients (136 males and 83 females) underwent the simultaneous reconstruction of maxillary defects in the Beijing Tongren Hospital, Capital Medical University, between January 2005 and December 2018 were reviewed. Age ranged from 16 to 78 years. Based on the proposed new classification of the maxillary defects, 22 patients with class Ⅰ defects (inferior maxillectomy), 44 patients with class Ⅱ defects (supperior maxillectomy), 132 patients with class Ⅲ defects (total maxillectomy) and 21 patients with class Ⅳ defects (extensive maxillectomy) were enrolled. Survival rate, functional and aesthetic outcomes of flaps were ev aluated. Survival analysis was performed in 169 patients with malignant tumor, Kaplan-Meier method was used to calculate the survival rate, and Log-rank method was used to compare the difference of survival rate in each group. Results: A total of 234 repairs for maxillary defects were performed in 219 patients. Fibula flaps were used in 4/13 of class Ⅰ defects; temporal muscle flaps (11/24, 45.8%) and anterolateral thigh flaps (6/24, 25.0%) used in class Ⅱ defects; temporal muscle flaps (71/128, 55.5%), anterolateral thigh flaps (6/24, 25.0%) and fibula flaps (12/128, 9.4%) used in class Ⅲ defects; and anterolateral thigh flaps (8/20, 40.0%) and rectus abdominis flaps (8/20, 40.0%) used in class Ⅳ defects. The success rate of local pedicled flaps was 95.6% (109/114) and that of free flaps was 95.8% (115/120). Thrombosis(10/234,4.3%) was a main reason for repair failure. Among the followed-up 88 patients, swallowing and speech functions recovered, 82 (93.2%) of them we re satisfied with appearance, and 75 (85.2%) were satisfied with visual field. The 3-year and 5-year overall survival rates were 66.5% and 63.6%, and the 3-year and 5-year disease-free survival rates were 57.1% and 46.2%, respectively, in the 169 patients with malignant tumors. Conclusion: A new classification of maxillary defects is proposed, on which suitable flaps are selected to offer patients good functional and aesthetic outcomes and high quality of life.

Precise resection and defect repair of external nose malignant tumor

xlomafota13 shared this article with you from Inoreader Precise resection and defect repair of external nose malignant tumor 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):15-21. doi: 10.3760/cma.j.cn115330-20210630-00399. 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.

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.

Onset and resolution failure of recurrent benign paroxysmal positional vertigo: the role of cervical range of motion

xlomafota13 shared this article with you from Inoreader Onset and resolution failure of recurrent benign paroxysmal positional vertigo: the role of cervical range of motion 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 29. doi: 10.1007/s00405-021-07226-1. Online ahead of print. ABSTRACT PURPOSE: To explore possible associations between cervical spine mobility, measured by cervical range of motion (CROM) and a possible earlier onset of recurrent benign paroxysmal positional vertigo (BPPV), as well as an increased failure rate of canalith repositioning procedures. METHODS: Medical records of 749 patients (247, 253 and 249 patients with a CROM ≤ 45°, between 45.1° and 55° and > 55.1°, respectively) with a first-time diagnosis of non-traumatic BPPV were included in this retrospective study. Age, gender, canal involvement and CROM values were treated as prospective prognostic factors for time of BPPV recurrence onset (RO) and number of manoeuvres needed to achieve resolution (resolution rate, RR). A multiple regression analysis was performed. RESULTS: A significant increase in the incidence of recur rent BPPV was found in patients with reduced CROM (139 [56.27%;], 102 [40.31%] and 87 [34.93%], respectively, belonging to ≤ 45°, 45.1°-55° and > 55.1° subgroups; X2 = 9.42, p = 0.008). A strong association between age, CROM and recurrent BPPV RO and RR was demonstrated, respectively (multiple correlation coefficients = 0.492678 and 0.593493, respectively, p value < 10-4). Canal involvement was in line with the previous experiences. CONCLUSION: The results from this retrospective analysis unveiled the previously unexplored relation between reduction in cervical spine mobility and BPPV recurrence and treatment failure. The data from this study do not indicate the mechanisms by which this comorbidity might directly cause recurrent BPPV. However, they may suggest CROM to be evaluated, in association with other known risk factors for increased susceptibility to BPPV recurrence.

The importance of systemic immune-inflammation index in obstructive sleep apnea syndrome

xlomafota13 shared this article with you from Inoreader The importance of systemic immune-inflammation index in obstructive sleep apnea syndrome 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 29. doi: 10.1007/s00405-021-07227-0. Online ahead of print. ABSTRACT OBJECTIVE: This study aims to explore the importance of systemic immune-inflammation index (SII) in patients diagnosed with obstructive sleep apnea (OSA). MATERIALS AND METHOD: In this study planned as a retrospective cohort, the files of the patients who presented with sleep apnea/snoring complaint between 10.01.2017 and 10.01.2021 and underwent polysomnography (PSG) and complete blood count analyses were reviewed. PSG findings (age, sex, body mass index (BMI), apnea-hypopnea index (AHI), mean oxygen saturation) were compared with SII in 194 patients meeting study eligibility criteria. RESULTS: Patients included in this study were divided into 4 groups by AHI value. Statistical difference was detected between the groups in terms of age, sex, body mass index (BMI), and mean oxygen saturation (p < 0.05). There is an ap proximately 30% positive statistically significant correlation between the severity of OSA and SII (p < 0.001). As for the mean SII values of the AHI groups, it was observed that the more severe AHI is, the higher the mean SII value is. The correlation between SII and the severity of OSA was found to be more significant than the correlation with neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR). CONCLUSION: There is a significant correlation between SII and the severity of OSA. This correlation is stronger compared to NLR and PLR. SII can be used to demonstrate the chronic systemic inflammation observed in OSA patients, and can be utilized as a simple and inexpensive biomarker as it can be easily calculated from the parameters present in routine blood analyses.
