xlomafota13 shared this article with you from Inoreader How I do it: endonasal transcribriform approach for resection of esthesioneuroblastoma Via leak of cerebrospinal fluid Acta Neurochir (Wien). 2022 Mar 16. doi: 10.1007/s00701-022-05178-x. Online ahead of print. ABSTRACT BACKGROUND: Olfactory neuroblastoma, also known as esthesioneuroblastoma, accounts for only 3-6% of sinonasal malignancies but confers a 40% 5-year overall survival. METHOD: The authors describe techniques for the endonasal, minimally invasive resection of an esthesioneuroblastoma in a 69-year-old man who presented with headaches and anosmia and describe surgical nuances and their effect on adjuvant therapy planning. CONCLUSION: This approach, along with microsurgical techniques, helped increase tumor visualization, improved marginal resection, and reduced surgical risk, which may improve patient outcomes. Multilayered reconstruction with a synthetic dural substitute and creation of a nasoseptal flap were performed to reduce postoperative cerebrospinal fluid leak.

Anatomic evaluation of the triceps tendon insertion at the proximal olecranon regarding placement of fracture fixation devices

xlomafota13 shared this article with you from Inoreader Anatomic evaluation of the triceps tendon insertion at the proximal olecranon regarding placement of fracture fixation devices Via radiol anat Surg Radiol Anat. 2022 Mar 17. doi: 10.1007/s00276-022-02921-y. Online ahead of print. ABSTRACT PURPOSE: Olecranon fractures, especially with a small proximal fragment, remain a surgical challenge. Soft tissue irritation and affection of the triceps muscle bear a risk of complications. In order to find an area for a soft-tissue sparing placement of implants in the treatment of olecranon fractures, we aimed to define and measure the segments of the proximal olecranon and eval uate them regarding possible plate placement. METHODS: We investigated 82 elbow joints. Ethical approval was obtained from the local ethics committee, After positioning in an arm holder and a posterior approach we described the morphology of the triceps footprint, evaluated and measured the surface area of the triceps and posterior capsule and correlated the results to easily measurable anatomical landmarks. RESULTS: We found a bipartite insertional footprint with a superficial tendinous triceps insertion of 218.2 mm2 (± 41.2, range 124.7-343.2), a capsular insertion of 159.3 mm2 (± 30.2, range 99.0-232.1) and a deep, muscular triceps insertion area of 138.1 mm2 (± 30.2, range 79.9-227.5). Olecranon height was 26.7 mm (± 2.3, range 20.5-32.2), and olecranon width was 25.3 mm (± 2.4, range 20.9-30.4). Average correlation between the size of the deep insertion and ulnar (r = 0.314) and radial length (r = 0.298) was obtained. CONC LUSIONS: We demonstrated the bipartite morphology of the distal triceps footprint and that the deep muscular triceps insertion area by its measured size could be a possible site for the placement of fracture fixations devices. The size correlates with ulnar and radial length. PMID:35301578 | DOI:10.1007/s00276-022-02921-y View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Radiological score of computed tomography scans predicts revision surgery for chronic rhinosinusitis

xlomafota13 shared this article with you from Inoreader Radiological score of computed tomography scans predicts revision surgery for chronic rhinosinusitis Via Acta Otorhinolaryngol Ital Acta Otorhinolaryngol Ital. 2022 Feb;42(1):63-74. doi: 10.14639/0392-100X-N1561. ABSTRACT OBJECTIVE: Evaluate computed tomography (CT) signs that predict need for revision endoscopic sinus surgery (ESS) of chronic rhinosinusitis (CRS). METHODS: CRS patients (n = 48) underwent routine sinus CT scans and baseline ESS in 2006-2011. Lund-Mackay (LM) scores and 43 other CT signs were analysed blinded from both sides. Patients filled in a questionnaire during the day of CT s canning. Follow-up data were collected from hospital records until January 2018. Associations were analysed by Fisher's exact, Mann Whitney U, Kaplan-Meier method with logrank test and Cox's proportional hazard model. RESULTS: Total LM score was not significantly associated with the need for revision ESS. The best predictive model was a sum of CT signs of non-detectable anatomy of inferior/middle turbinates, obstructed frontal recess, and previous sinus surgery. Using these CT findings, we formed a Radiological Score (RS) (min-max, 0-3 points). Having at least one RS point was significantly associated with the need for revision ESS during the average follow-up of 10.7 years (p = 0.008, Logrank test). CONCLUSION: We identified a radiologic score that was able to predict the need for revision ESS, which is probably useful in predicting CRS outcomes.

Immunophenotypic characteristics of T lineage acute lymphoblastic leukemia: absence of immaturity markers-TdT, CD34 and HLADR is not uncommon

xlomafota13 shared this article with you from Inoreader Immunophenotypic characteristics of T lineage acute lymphoblastic leukemia: absence of immaturity markers-TdT, CD34 and HLADR is not uncommon Via American Journal of Blood Research Am J Blood Res. 2022 Feb 15;12(1):1-10. eCollection 2022. ABSTRACT INTRODUCTION: T ALL may show variable morphological features and immunophenotypic analysis for characterisation of immature nature of these cells is needed to establish a diagnosis and distinguish from reactive conditions and mature T cell leukemias. Sometimes immaturity markers-CD34, TdT and HLA DR may not be expressed by blasts. The aim of the present study was to analyse immunophenotype of T ALLs especially with respect to absence of immaturity markers. METHODS: Thirty-eight cases of T ALL diagnosed over a period of two and half years were analysed retrospectively with respect to clinical features, haematological features and flow cytometric immunophenotyping for T, B, Myeloid and immaturity markers. Student's T-test was used for comparing quantitative data and Chi-square test/Fishers exact T-test for qualitative variables. P value less tha n 0.05 was considered significant. RESULTS: The most common T-lineage marker expressed was cCD3 and CD7 which were expressed in 100% cases followed by CD5 in 86.8% cases. The most common immaturity marker expressed was TdT (39.5% cases) followed by CD34 (34.2% cases). Thirteen cases (34.2%) were negative for all three of the immaturity markers i.e. TdT-/CD34-/HLADR. Absence of CD34 was associated with absence of expression of HLA DR (P<0.05) and aberrant expression of B lineage markers (P<0.05). CONCLUSION: T-ALL is a rare and aggressive disease. Many cases lack immaturity markers viz, TdT, CD34 and HLADR. In such cases a comprehensive approach taking into account the clinical presentation, cytomorphology and immunophenotyping is diagnostic in experienced hands. Further, molecular studies may be needed to aid diagnosis. PMID:35291252 | PMC:PMC8918703 View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

BMI as a risk factor for the development of chronic rhinosinusitis: a prospective population-based study

xlomafota13 shared this article with you from Inoreader BMI as a risk factor for the development of chronic rhinosinusitis: a prospective population-based study 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 Mar 19. doi: 10.1007/s00405-022-07320-y. Online ahead of print. ABSTRACT PURPOSE: Obesity is a growing, global health problem and previous cross-sectional studies have demonstrated an association between obesity and chronic rhinosinusitis (CRS). There is, however, a lack of prospective studies regarding the impact of obesity on developing (new-onset) CRS. METHODS: Questionnaire-based data (n = 5769) relating to new-onset CRS and Body Mass Index (BMI) were collected in 2013 and 2018 from the Telemark population study in Telemark, Norway. Odds ratios for the risk of new-onset CRS in 2018 in relation to BMI in 2013 were calculated, adjusted for smoking habits, asthma, gender and age. RESULTS: When comparing the group with normal weight (18.5 ≤ BMI < 25) with the obese group (BMI ≥ 30), the odds of new-onset CRS was 53% higher [OR 1.53 (1.11, 2.10)] in the obese group. CONCLUSION: CR S is a multifactorial disease with different phenotypes and it is important to consider obesity when assessing patients with CRS in a clinical setting.

Voice Symptoms and Wellbeing in School Teachers in England

xlomafota13 shared this article with you from Inoreader Voice Symptoms and Wellbeing in School Teachers in England Via Journal of Voice Negative psychological factors such as depression and other common mental disorders have been found to be associated with voice problems in teachers. However, there is little research with teachers that investigates the relationship between positive psychological factors such as wellbeing and voice problems. Although negative and positive mental states are on a continuum of psychological health, research suggests negative and positive effects are not necessarily inversely correlated and therefore need to be investigated separately.

Deep Learning Forecasts the Occurrence of Sleep Apnea from Single-Lead ECG

xlomafota.13 shared this article with you from Inoreader Deep Learning Forecasts the Occurrence of Sleep Apnea from Single-Lead ECG Via Latest Results for Cardiovascular Engineering and Technology Abstract Objectives Sleep apnea is the most common sleep disorder that leads to serious health complications if not treated early. Forecasting apnea occurrence ahead in time provides the opportunity to take appropriate actions to control and manage it. Methods A novel framework for forecasting the occurrence of apnea from single-lead electrocardiogram (ECG) based on deep recurrent neural networks is proposed. ECG R-peak amplitudes and R-R intervals are extracted and aligned using power spectral analysis, and recurrent deep learning models are developed to extract the most predictive ECG features and forecast the occurrence of apnea. Results The performance of the proposed approach was validated in forecasting apnea events up to five minutes in future on a dataset of 70 sleep recordings. A forecasting accuracy of up to 94.95% was achieved which was higher than the performance of conventional multilayer perceptron (p < 0.05) and other state-of-the-art techniques. Conclusions The proposed deep learning approach was successful in forecasting the occurrence of sleep apnea from single-lead ECG. It can therefore be adopted in wearable sleep monitors for the management of sleep apnea. Our developed algorithms are publicly available on GitHub. View on the web Inoreader.

Real-time eye state recognition using dual convolutional neural network ensemble

xlomafota.13 shared this article with you from Inoreader Real-time eye state recognition using dual convolutional neural network ensemble Via Latest Results for Journal of Real-Time Image Processing Abstract Automatic recognition of the eye states is essential for diverse computer vision applications related to drowsiness detection, facial emotion recognition (FER), human–computer interaction (HCI), etc. Existing solutions for eye state detection are either parameter intensive or suffer from a low recognition rate. This paper presents the design and implementation of a vision-based system for real-time eye state recognition on a resource-constrained embedded platform to tackle these issues. The designed system uses an ensemble of two lightweight convolutional neural networks (CNN), each trained to extract relevant information from the eye patches. We adopted transfer-learning-based fine-tuning to overcome the over-fitting issues when training the CNNs on small sample eye state datasets. Once trained, these CNNs are integrated and jointly fine-tuned to achieve enhanced performance. Experimental results manifest the effectiveness of the proposed eye state recognizer that is robust and computationally efficient. On the ZJU dataset, the proposed DCNNE model delivered the state-of-the-art recognition accuracy of 97.99% and surpassed the prior best recognition accuracy of 97.20% by 0.79%. The designed model also achieved competitive results on the CEW and MRL datasets. Finally, the designed CNNs are optimized and ported on two different embedded platforms for real-world applications with real-time performance. The complete system runs at 62 frames per second (FPS) on an Nvidia Xavier device and 11 FPS on a low-cost Intel NCS2 embedded platform using a frame size of 640 \(\times\) 480 pixels resolution.

Microglia phenotypes are associated with subregional patterns of concomitant tau, amyloid-β and α-synuclein pathologies in the hippocampus of patients with Alzheimer’s disease and dementia with Lewy bodies

xlomafota.13 shared this article with you from Inoreader Microglia phenotypes are associated with subregional patterns of concomitant tau, amyloid-β and α-synuclein pathologies in the hippocampus of patients with Alzheimer's disease and dementia with Lewy bodies Via Latest Results for Acta Neuropathologica Communications Abstract The cellular alterations of the hippocampus lead to memory decline, a shared symptom between Alzheimer's disease (AD) and dementia with Lewy Bodies (DLB) patients. However, the subregional deterioration pattern of the hippocampus differs between AD and DLB with the CA1 subfield being more severely affected in AD. The activation of microglia, the brain immune cells, could play a role in its selective volume loss. How subregional microglia populations vary within AD or DLB and across these conditions remains poorly understood. Furthermore, how the nature of the hippocampal local pathological imprint is associated with microglia responses needs to be elucidated. To this purpose, we employed an automated pipeline for analysis of 3D confocal microscopy images to assess CA1, CA3 and DG/CA4 subfields microglia responses in post-mortem hippocampal samples from late-onset AD (n = 10), DLB (n = 8) and age-matched control (CTL) (n =� ��11) individuals. In parallel, we performed volumetric analyses of hyperphosphorylated tau (pTau), amyloid-β (Aβ) and phosphorylated α-synuclein (pSyn) loads. For each of the 32,447 extracted microglia, 16 morphological features were measured to classify them into seven distinct morphological clusters. Our results show similar alterations of microglial morphological features and clusters in AD and DLB, but with more prominent changes in AD. We identified two distinct microglia clusters enriched in disease conditions and particularly increased in CA1 and DG/CA4 of AD and CA3 of DLB. Our study confirms frequent concomitance of pTau, Aβ and pSyn loads across AD and DLB but reveals a specific subregional pattern for each type of pathology, along with a generally increased severity in AD. Furthermore, pTau and pSyn loads were highly correlated across subregions and conditions. We uncovered tight associations between microglial changes and the subfield pathological imprint. Our findi ngs suggest that combinations and severity of subregional pTau, Aβ and pSyn pathologies transform local microglia phenotypic composition in the hippocampus. The high burdens of pTau and pSyn associated with increased microglial alterations could be a factor in CA1 vulnerability in AD. View on the web Inoreader. Take back control of your news feed.

Laser‐Assisted Sialolithotripsy: A Correlation of Objective and Subjective Outcomes

xlomafota13 shared this article with you from Inoreader Laser‐Assisted Sialolithotripsy: A Correlation of Objective and Subjective Outcomes Via The Laryngoscope Objective To analyze the long-term symptomatic results of laser-assisted sialolithotripsy (LAS) in cases of obstructive sialolithiasis and correlate with objective criteria using diagnostic sialendoscopy (DS) as a method of examination. Methods This is a retrospective study comprising 50 consecutive patients who underwent holmium-YAG LAS and completed follow-up of at least 6 months. Symptom scoring and endoscopic scoring were done at 6 weeks and 6 months intervals for further study purposes. Results At the end of 6 weeks post-LAS, 70% patients were asymptomatic (A-sym) and only 30% had residual symptoms (Sym). However, obstructed duct (OB-duct) was observed on endoscopic scoring in 88% due to stenosis, residual stones, or both stenosis and residual stones. The obstructed ducts were treated in outpatient clinic and followed up over time, leading to 98% of patients being in A-sym group at the end of study period of 6 months. At the end of study, 82% of patients had clear duct (CL-duct). Conclusion Holmium LAS is a viable option for the management of intermediate-sized stones. LAS if used judiciously, and in properly selected cases, has high rate of stone fragmentation and symptom resolution. A vigilant postoperative protocol taking into account residual mealtime symptoms and altered salivary characteristics combined with early DS can help identify and treat patients with residual stone fragments and ductal stenosis.
