Up‐front neck dissection followed by chemoradiotherapy for T1–T3 hypopharyngeal cancer with advanced nodal involvement

xlomafota13 shared this article with you from Inoreader Up‐front neck dissection followed by chemoradiotherapy for T1–T3 hypopharyngeal cancer with advanced nodal involvement Via Head & Neck Abstract Background The advantage of up-front neck dissection (UFND) followed by chemoradiotherapy (CRT) for hypopharyngeal cancer (HPC) with advanced neck involvement remains controversial. We aimed to determine the indications. Methods The data of 41 and 14 patients with stage IVA/B (T1–T3 and ≥N2a) HPC who underwent UFND followed by CRT and received CRT, respectively, were retrospectively analyzed and compared. Results The 5-year overall survival (OS) and disease-specific survival rates for the UFND and CRT groups were 61% and 52% (p = 0.1019), and 89% and 74% (p = 0.2333), respectively. Moreover, patients aged ≥70 years or those with a pulmonary disease history had a significantly poorer prognosis due to aspiration pneumonia in the UFND group. The 5-year regional control (RC) for the UFND and CRT groups were 92% and 57%, respectively (p = 0.0001). Conclusions UFND followed by CRT was feasible with satisfactory RC. To further improve OS, aspiration pneumonia prevention is essential. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Orocutaneous Fistula After Oral Cavity Resection and Reconstruction: Systematic Review and Meta-Analysis

xlomafota13 shared this article with you from Inoreader Orocutaneous Fistula After Oral Cavity Resection and Reconstruction: Systematic Review and Meta-Analysis Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Sep 23:34894211047463. doi: 10.1177/00034894211047463. Online ahead of print. ABSTRACT OBJECTIVE: Orocutaneous fistula (OCF) after reconstruction for oral cavity resection can lead to prolonged hospitalization and adjuvant treatment delay. Few studies have examined factors leading to OCF after oral cavity resection. Primary objective: evaluate overall incidence and factors associated with OCF after oral cavity reconstruction. DATA SOURCES : Scopus 1960-database was searched for terms: "orocutaneous fistula," "oro cutaneous fistula," "oral cutaneous fistula," "orocervical fistula," "oral cavity salivary fistula." REVIEW METHODS: English language studies with >5 patients undergoing reconstruction after oral cavity cancer resection were included. About 1057 records initially screened; 214 full texts assessed; 78 full-texts included. PRISMA guidelines were followed, and MINORS criteria used to assess risk of bias. Data were pooled using random-effects model. Primary outcome was OCF incidence. Meta-analysis to determine the effect of preoperative radiation on OCF conducted on 12 eligible studies. Pre-collection hypothesis was that prior radiation therapy is associated with increased OCF incidence. Post-collection analyses: free versus pedicled flaps; mandible-sparing versus segmental mandibulectomy. RESULTS: Seventy-eight studies were included in meta-analysis of overall OCF incidence. Pooled effect size sh owed overall incidence of OCF to be 7.71% (95% CI, 6.28%-9.13%) among 5400 patients. Meta-analysis of preoperative radiation therapy on OCF showed a pooled odds ratio of 1.68 (95% CI, 0.93-3.06). OCF incidence was similar between patients undergoing free versus pedicled reconstruction, or segmental mandibulectomy versus mandible-sparing resection. CONCLUSION: Orocutaneous fistula after oral cavity resection has significant incidence and clinical impact. Risk of OCF persists despite advances in reconstructive options; there is a trend toward higher risk after prior radiation. PMID:34553635 | DOI:10.1177/000348942 11047463 View on the web Inoreader.

A contemporary narrative review to guide molecular epidemiology of oral submucous fibrosis

xlomafota13 shared this article with you from Inoreader A contemporary narrative review to guide molecular epidemiology of oral submucous fibrosis Via International Journal of Molecular Epidemiology and Genetics Int J Mol Epidemiol Genet. 2021 Aug 15;12(4):61-70. eCollection 2021. ABSTRACT Oral submucous Fibrosis (OSMF) is a chronic disease that mainly affects the upper part of the aerodigestive tract. Areca nut and betel quid chewing has been established as the most significant causative factor for this condition. While OSMF is a predominantly Asian disease, the migrant populations from the region have taken the disease across the globe. Additionally, areca nut is now easily accessible in flavors and aggressively marketed. Many research activities have been undertaken for decades to understand the etiopathogenesis and risk factors of OSMF. Although OSMF is a slowly progressing disease, it has the potential to transform to an oral malignancy. This article is an attempt to review the literature and provide an update on its prevalence, etiopthogenesis and its diagnosis. We also highlight certain clinical, histopathological and molecular features that aid in the diagnosis and prognostication of OSMF, highlighting the importance of identifying the possibly high risk OSMF that is prone to malignant transformation. Using this information, future directions can be developed to include treatmentof OSMF through a dynamic gene-specific approach. PMID:34552689 | PMC:PMC8449189 View on the web Inoreader.

The Expression and Regulation of Na+-K+-ATPase in Nasal Epithelial Cells of Chronic Rhinosinusitis with Nasal Polyps

xlomafota13 shared this article with you from Inoreader The Expression and Regulation of Na<sup>+</sup>-K<sup>+</sup>-ATPase in Nasal Epithelial Cells of Chronic Rhinosinusitis with Nasal Polyps Via O.R.L. Journal for oto-rhino-laryngology and its borderlands Objective: Na+-K+-ATPase (NKA) is essential in maintaining cell permeability, reserving potential energy, and preventing cellular edema. Nevertheless, how NKA expression is altered and regulated in chronic rhinosinusitis with nasal polyps (CRSwNPs) remain uncertain. Therefore, the present study aimed to explore the expression and regulation of NKA in CRSwNP. Methods: NKA immunolabeling was assessed by the immunohistochemistry method, NKA prote in levels were detected with the Western blotting method, and mRNA levels of NKA and aquaporin-5 (AQP5) were assayed by real-time PCR in nasal tissues from CRSwNP and control subjects. The co-localization of NKA with inflammatory cells was evaluated by immunofluorescence staining. In addition, human nasal epithelial cells (HNECs) were cultured and stimulated using various stimulators to evaluate the regulation of NKA. Results: We found significantly decreased NKA positive cells, NKA protein levels, and mRNA levels of NKA and AQP5 in nasal tissues from CRSwNP patients compared to control subjects, especially in eosinophilic CRSwNP. Furthermore, NKA mRNA levels in HNECs were downregulated by staphylococcal enterotoxin B (SEB), lipopolysaccharides (LPSs), inflammatory cytokine (IFN)-γ, IL-4, IL-13, and IL-1β. Conclusion: NKA and AQP5 expressions were decreased in CRSwNP. NKA in HNECs could be suppressed by SEB, LPS, IFN-γ, IL-4, IL-13, and IL-1β. Impairm ent of NKA may contribute to the genesis and development of CRSwNP via inducing AQP5 downregulation and edema. ORL View on the web Inoreader. Take back control of your news feed.

Menopause and its Effect on Voice

xlomafota13 shared this article with you from Inoreader Menopause and its Effect on Voice Via Otolaryngology Indian Abstract This study was designed to study the impact of menopause on voice quality. Cross-sectional Observational study with a total of 100 subjects. All subjects underwent biochemical analysis which included thyroid function tests, estrogen levels, progesterone levels and underwent voice analysis using the VAUGHMI voice analyser software. 50 postmenopausal females as cases and 50 premenopausal females as controls were taken for the study. The females were of the age group 35–55 yrs in order to remove age as confounding factor. The primary outcome measure was Total score, calculated based on harshness, hoarseness and breathiness. The postmenopausal females had a poorer voice quality than the premenopausal females (Total score 1.62 vs 2.48, p < 0.001). There was a significant difference between the fundamental frequency and pitch and perturbation in frequency of the postmenopausal females as compared to premenopausal females. The difference in the pertu rbation in the intensity of the voice was not significant. No linear correlation could be established between the voice quality and oestrogen or progesterone levels but the intergroup variation of the two parameters was significant. The premenopausal females have better voice quality than postmenopausal females. The relationship between hormonal level and voice quality couldn't be established. Further studies are required to assess the relation of hormone levels & voice quality with the possibility of exploring voice cosmesis. Level of Evidence Level 3. View on the web Inoreader.

Intensity patterns at the peaks of brain activity in fMRI and PET are highly correlated with neural models of spatial integration

xlomafota13 shared this article with you from Inoreader Intensity patterns at the peaks of brain activity in fMRI and PET are highly correlated with neural models of spatial integration Via Laryngologie Eur J Neurosci. 2021 Sep 22. doi: 10.1111/ejn.15469. Online ahead of print. ABSTRACT Spatial integration during the brain's cognitive activity prompts changes in energy used by different neuroglial populations. Nevertheless, the organization of such integration in 3D -brain activity remains undescribed from a quantitative standpoint. In response, we applied a cross-correlation between brain activity and integrative models, which yielded a deeper understanding of information integration in functional brain mapping. We analyzed four datasets obtained via fundamentally different neuroimaging techniques (fMRI and PET) and found that models of spatial integration with an increasing input to each step of integration were significantly more correlated with brain activity than models with a constant input to each step of integration. In addition, marking the voxels with the maximal correlation, we found exceptionally high inter-subject consistency wi th the initial brain activity at the peaks. Our method demonstrated for the first time that the network of peaks of brain activity is organized strictly according to the models of spatial integration independent of neuroimaging techniques. The highest correlation with models integrating an increasing at each step input suggests that brain activity reflects a network of integrative processes where the results of integration in some neuroglial populations serve as an input to other neuroglial populations.

Comparison of Olfactory Cleft Width and Volumes in Patients with COVID-19 Anosmia and COVID-19 Cases Without Anosmia

xlomafota13 shared this article with you from Inoreader Comparison of Olfactory Cleft Width and Volumes in Patients with COVID-19 Anosmia and COVID-19 Cases Without Anosmia Via O.R.L. Journal for oto-rhino-laryngology and its borderlands Introduction: The aim of this study was to assess the relationship between olfactory cleft width/volume and COVID-19-related anosmia. Methods: This study consisted of PCR-proven COVID-19 patients. Cases with COVID-19-related anosmia constituted Group 1 and cases without any olfactory dysfunction (OD) throughout COVID-19 infection or after recovery constituted Group 2. A total of 50 patients were included in the study, comprising 24 cases in Group 1 and 26 cases in Group 2. Group 1 patients underwent a 4-item-odor identification test during active symptoms and a Sniffin' Sticks test after reconversion of PCR results to negative. All patients in Group 2 also underwent the Sniffin' Stick test to document normosmia. All cases had paranasal sinus CT performed. Olfactory cleft widths and olfactory volumes were measured. The differences in width and volume between groups and the correlation with odor test scores (threshold-discrimination-identification [TDI]) were calculated. In addition, regression analyzes analysis was performed for cleft widths, volumes, and TDI scores according to age. Results: Olfactory cleft widths and olfactory volumes were significantly higher in Group 1 than those in Group 2 (p = 0.001; p #x3c; 0.01). There was a significant negative correlation between total TDI scores and olfactory cleft widths and total olfactory volumes (r = −0.665; r = −0.731, respectively). Patients younger than 40 years of age had significantly higher right olfactory cl eft width, left olfactory cleft width, and olfactory cleft volume than those in patients older than 40 years of age (p = 0.004, p = 0.005, p = 0.003; p #x3c; 0,01, respectively). However, patients younger than 40 years of age had a significantly lower total TDI score and in all other values individually (t-d-i) than those in patients older than 40 years of age (p = 0.004; p #x3c; 0.01). Conclusion: Patients with COVID-19-related OD had larger olfactory cleft width and volumes than those without OD in this study. Total TDI score was found to be inversely correlated with cleft width and volume. ORL View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

The Effect of Somatosensorial System on Vestibular System

xlomafota13 shared this article with you from Inoreader The Effect of Somatosensorial System on Vestibular System Via Otolaryngology Indian Abstract The aim of this study was to investigate the effects of the somatosensory system on the vestibular system and the interconnected ways they work together to maintain balance. The study was conducted on 54 individuals (27 females and 27 males), aged between 18–25 years. vHIT as well as cVEMP tests were used to evaluate the participants. Tests were carried out while sitting, standing on firm surface and standing on foam respectively. According to the posterior vHIT results, there was a significant difference between VOR gains obtained while sitting and standing on firm surface in right side as well as on the left side (p < 0,01). Moreover, when VOR gains in standing on firm and standing on foam results were compared to each other, statistical significance was found right and left posterior canals (p < 0,05). Concerning the results obtained from VEMP, a statistically significant difference was seen in the comparison of P1-N1 amp litudes of the right side on firm surface and standing on foam (p < 0,01). When the inputs from somatosensorial system are disturbed, the parts of the vestibular system that are primarily affected are the posterior SSC, saccule and inferior vestibular nerve. This can be interpreted as the inferior vestibular nerve being more affected than the superior vestibular nerve when posture is disturbed due to somatosensory cues being unavailable or unstable.

xlomafota13 shared this article with you from Inoreader Validation of a French version of the Sunnybrook facial grading system Via Laryngologie Eur Ann Otorhinolaryngol Head Neck Dis. 2021 Sep 17:S1879-7296(21)00181-2. doi: 10.1016/j.anorl.2021.08.003. Online ahead of print. ABSTRACT BACKGROUND: The aim of this study was to translate the Sunnybrook Facial Grading System and its specific criteria into French and validate its use by French-speaking physicians for facial palsy evaluation. MATERIAL AND METHODS: The original English version of the Sunnybrook Facial Grading System and its specific criteria was translated into French according to international standards. Twenty videos of patients with a wide range of facial palsy in terms of duration and severity were independently rated, twice each, by 6 physicians with varied experience in facial palsy care. Internal consistency and intra- and inter-rater reliability were analyzed. RESULTS: The French version of Sunnybrook Facial Grading System and its specific criteria both showed good internal consistency, with Cronbach alph a of 0.84 and 0.86 respectively. Inter-rater reliability was excellent in both sessions for the composite score, the score of symmetry at rest and during voluntary movement and synkinesis: intraclass correlation coefficient (ICC) between 0.77 and 0.98. Intra-rater reproducibility on the composite score and subscores was also excellent and comparable for expert, experienced and novice physicians, with an average ICC of 0.95. CONCLUSION: The French version of the Sunnybrook Facial Grading System and its specific criteria is reliable, reproducible and easy to use by French-speaking teams for facial palsy evaluation.

Ki-67/MIB-1 and Recurrence in Pituitary Adenoma

xlomafota13 shared this article with you from Inoreader Ki-67/MIB-1 and Recurrence in Pituitary Adenoma Via Journal of Neurological Surgery Part B: Skull Base J Neurol Surg B Skull Base DOI: 10.1055/s-0041-1735874 Objectives Ki-67/MIB-1 is a marker of cellular proliferation used as a pathological parameter in the clinical assessment of pituitary adenomas, where its expression has shown utility in predicting the invasiveness of these tumors. However, studies have shown variable results when using Ki-67/MIB-1 association with recurrence. The purpose of this study is to determine if a high Ki-67/MIB-1 labeling index (LI) is predictive of recurrence in pituitary adenomas. Methods A retrospective chart review was performed for patients undergoing pituitary adenoma resection with at least 1 year of follow-up. Additionally, systematic data searches were performed and included studies that correlated recurrence rate to Ki-67/MIB-1 LI. Our institutional data were included in a synthesis with previously published data. Results Our institutional review included 79 patients with a recurrence rate of 26.6%. We found that 8.8% of our patients had a high Ki-67/MIB-1 LI (>3%); however, high Ki-67/MIB-1 was not associated with recurrence. The systematic review identified 244 articles and 49 full-text articles that were assessed for eligibility. Quantitative analysis was performed on 30 articles including our institutional data and 18 studies reported recurrence by level of Ki-67/MIB-1 LI. Among studies that compared Ki-67/MIB-1 ≥3 vs. <3%, 10 studies reported odds ratios (OR) greater than 1 of which 6 were statistically significant. A high Ki-67/MIB-1 had higher odds of recurrence via the pooled odds ratio (OR = 4.15, 95% confidence interval [CI]: 2.31–7.42). Conclusion This systematic review suggests that a high Ki-67/MIB-1 should prompt an increased duration of follow-up due to the higher odds of recurrence of pituitary adenoma.
