Pilonidal sinus disease (PSD) is a common condition associated with significant morbidity and healthcare costs. High recurrence rates still pose a considerable challenge in managing PSD, with no universally accepted guideline in place to guide management. Laser hair epilation offers a way to reduce recurrence rates with reports within the current literature demonstrating positive outcomes compared to alternative approaches. This review was conducted by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement standards. The primary outcome measure was the recurrence rate of PSD at a minimum of one year following laser hair epilation. The electronic databases of MEDLINE, EMBASE, CINAHL, Google Scholar, PubMed, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched. OpenMeta Analyst (Brown University School of Public Health, Providence, RI) software was used for data synthesis. Three randomized controlled trials met the inclusion criteria with laser hair epilation treatments offering a significant reduction in PSD recurrence rates on odds ratio analysis: 0.319 ( 0.160, 0.636), P-value = 0.0001. Secondary outcomes involving patient disability days, caregiver disability days, health-related quality-of-life (HRQOL) scores, healthcare satisfaction scores, and perceived stigma were discussed qualitatively. The authors offer a decisive recommendation in favor of laser hair epilation in PSD; however, they recommend further high-quality trials to investigate the ideal timing and frequency of laser hair epilation sessions.

Cerebral venous sinus thrombosis (CVST), a rare but deadly disorder, causes papilledema as well as a number of frequent clinical symptoms, including excruciating headaches, focal seizures, and paralysis on one or both sides of the body. In this intriguing case study, we present the clinical narrative of a 45-year-old man who sought medical attention due to severe headaches persisting for two days. Concurrently, he experienced an abrupt onset of tingling and numbness in his left upper arm. Remarkably, magnetic resonance venography (MRV) revealed an absence of the sigmoid sinus, left transverse sinus, left jugular vein, and superior sagittal sinus, adding complexity to the diagnostic puzzle. Despite this anomaly, conventional brain MRI findings appeared normal. The patient reported a significant reduction in headache intensity following treatment, which included a year-long course of anticoagulant therapy. Subsequently, he gradually regained his health, underscoring the importance of multidisciplinary approaches in managing such challenging cases. This example emphasizes the significance of considering CVST while developing a differential diagnosis of various neurological disorders. Given the vast spectrum of clinical symptoms associated with CVST, it should be taken into account as a potential causative factor in a number of neurological illnesses, in order for patients to experience the best outcomes, quick diagnosis, and quality care.

UNASSIGNED: SAPIEN3 (S3) is a ubiquitous redo-transcatheter aortic valve (TAV) replacement alternative for degenerated Evolut valves, but S3 sizing for S3-in-Evolut remains unclear. We sought to compare the impact of in vivo computed tomography (CT)-sizing on redo-TAV feasibility for S3-in-Evolut with traditional bench-sizing.
UNASSIGNED: CT scans of 290 patients treated using Evolut R/PRO/PRO+ between July 2015 and December 2021 were analyzed. S3-in-Evolut was simulated using S3 outflow/neoskirt plane (NSP) at node-6, -5, and -4. CT-sizing for S3 was determined by averaging 4 areas of the Evolut stent frame at NSP level and 3 nodes below. Redo-TAV was deemed feasible if the NSP was below the coronaries, or the narrowest valve (virtual S3)-to-aorta distance was >4 mm. Risk of prosthesis-patient mismatch was estimated using predicted indexed-effective orifice area.
UNASSIGNED: Compared with bench-sizing, CT-sizing yielded smaller S3 size in 82% at node-6, 81% at node-5, and 84% at node-4. Factors associated with CT-sizing less than bench-sizing were larger index Evolut size, underexpansion of index Evolut, and shallower implant depth (all P<0.05). CT-sizing increased redo-TAV feasibility by +8% at node-6, +10% at node-5, and +4% at node-4. Redo-TAV feasibility increased with annulus size, sinotubular junction dimensions, coronary heights, index Evolut size, deeper Evolut implant depth, and lower NSP levels (all P<0.05). CT-sizing had a slightly higher estimated risk of severe prosthesis-patient mismatch (9% at node-6, 7% at node-5, and 6% at node-4), which could be mitigated by changing the NSP.
UNASSIGNED: CT-sizing for S3-in-Evolut is associated with higher feasibility of redo-TAV compared with bench-sizing, potentially reducing the risk of excessive oversizing and S3 underexpansion. Further validation using real-world clinical data is necessary.

Elexacaftor/tezacaftor/ivacaftor (ETI) therapy has revolutionized the treatment of cystic fibrosis (CF) for most affected individuals but the effects of treatment on sinus microbiota are still unknown. Changes to the airway microbiota in CF are associated with disease state and alterations to the bacterial community after ETI initiation may require changes to clinical management regimens. We collected sinus swab samples from the middle meatus in an observational study of 38 adults with CF and chronic rhinosinusitis (CRS) from 2017 to 2021 and captured the initiation of ETI therapy. We performed 16S and custom amplicon sequencing to characterize the sinus microbiota pre- and post-ETI. Real-time quantitative PCR (RT-qPCR) was performed to estimate total bacterial abundance. Sinus samples from people with CF (pwCF) clustered into three community types, dependent on the dominant bacterial organism: a Pseudomonas-dominant, Staphylococcus-dominant, and mixed dominance cluster. Shannon\'s diversity index was low and not significantly altered post-ETI. Total bacterial load was not significantly lowered post-ETI. Pseudomonas spp. abundance was significantly reduced post-ETI, but eradication was not observed. Staphylococcus spp. became the dominant organism in most individuals post-ETI and we showed the presence of methicillin-resistant Staphylococcus aureus (MRSA) in the sinus both pre- and post-ETI. We also demonstrated that the sinus microbiome is predictive of the presence of Pseudomonas spp., Staphylococcus spp., and Serratia spp. in the sputum. Pseudomonas spp. and Staphylococcus spp., including MRSA, persist in the sinuses of pwCF after ETI therapy, indicating that these pathogens will continue to be important in CF airway disease management in the era of highly effective modulator therapies (HEMT).IMPORTANCEHighly effective modulator therapies (HEMT), such as elexacaftor/tezacaftor/ivacaftor (ETI), for cystic fibrosis (CF) have revolutionized patient care and quality of life for most affected individuals. The effects of these therapies on the microbiota of the airways are still unclear, though work has already been published on changes to microbiota in the sputum. Our study presents evidence for reduced relative abundance of Pseudomonas spp. in the sinuses following ETI therapy. We also show that Staphylococcus spp. becomes the dominant organism in the sinus communities of most individuals in this cohort after ETI therapy. We identified methicillin-resistant Staphylococcus aureus (MRSA) in the sinus microbiota both pre- and post-therapy. These findings demonstrate that pathogen monitoring and treatment will remain a vital part of airway disease management for people with cystic fibrosis (pwCF) in the era of HEMT.

OBJECTIVE: Sinus osteotomy is currently performed in equine surgery with conventional surgical methods, such as trephines and oscillating bone saw, leading to subsequent trauma to the bone during cutting. Piezoelectric devices are now used in maxillofacial surgery in humans as a standard tool as it is less traumatic than the oscillating bone saw and shortens the healing period. The aim of this study was to show that the piezoelectric device can be used for equine sinus surgery, compare its use with the oscillating bone saw, and describe the outcome of cases involving osteotomy performed with a piezoelectric surgical device.
METHODS: 10 horse specimens for cadaveric study and 11 client-owned equines for clinical evaluation.
METHODS: Each cadaveric head underwent a frontonasal bone flap on a randomly assigned side with the piezotome and the oscillating bone saw on the opposite side. Surgical time was recorded for every procedure, and gross examination was performed. A Welch t test was used to compare the surgical time between piezoelectric and oscillating saw use. For the clinical study, animals presented for sinonasal surgery at the hospital from March through October 2023 were included.
RESULTS: Osteotomy was possible with the piezotome in all animals. Surgical time was significantly increased when using the piezotome in comparison with the oscillating saw (P < .05). All clinical patients were treated adequately for the sinonasal disorder they were presented for using the piezotome instead of the oscillating saw. No adverse effects nor long-term complications related to its use have been noted, and preservation of the surrounding soft tissues was evident.
CONCLUSIONS: The use of a piezoelectric device in equine surgery is feasible. However, the cadaveric study showed an increased surgical time to perform a frontonasal bone flap.

A 16-year-old pony gelding presented with epistaxis and a head tilt. Referral skull radiographs suggested an ethmoid hematoma. Concurrent neurologic abnormalities prompted contrast-enhanced CT of the head and cranial neck, revealing numerous hyperattenuating masses throughout the brain and paranasal sinuses, along with a large osteolytic mass in the second cervical vertebra. The vertebral mass extended into the vertebral canal, causing focal extradural compressive myelopathy. These findings were inconsistent with ethmoid hematoma and metastatic hemangiosarcoma or malignant melanoma were prioritized as potential causes for the clinical signs. Postmortem examination confirmed the sinonasal, intracranial, and vertebral masses as hemangiosarcoma, and additionally revealed innumerable thoracoabdominal metastatic lesions and hemorrhagic foci. A final diagnosis of disseminated hemangiosarcoma was made. In this study, CT proved invaluable for evaluating the severity and characterizing regional disease and neural involvement, directly affecting case management decisions.

OBJECTIVE: Preoperative imaging plays a pivotal role in sinus surgery where CTs offer patient-specific insights of complex anatomy, enabling real-time intraoperative navigation to complement endoscopy imaging. However, surgery elicits anatomical changes not represented in the preoperative model, generating an inaccurate basis for navigation during surgery progression.
METHODS: We propose a first vision-based approach to update the preoperative 3D anatomical model leveraging intraoperative endoscopic video for navigated sinus surgery where relative camera poses are known. We rely on comparisons of intraoperative monocular depth estimates and preoperative depth renders to identify modified regions. The new depths are integrated in these regions through volumetric fusion in a truncated signed distance function representation to generate an intraoperative 3D model that reflects tissue manipulation RESULTS: We quantitatively evaluate our approach by sequentially updating models for a five-step surgical progression in an ex vivo specimen. We compute the error between correspondences from the updated model and ground-truth intraoperative CT in the region of anatomical modification. The resulting models show a decrease in error during surgical progression as opposed to increasing when no update is employed.
CONCLUSIONS: Our findings suggest that preoperative 3D anatomical models can be updated using intraoperative endoscopy video in navigated sinus surgery. Future work will investigate improvements to monocular depth estimation as well as removing the need for external navigation systems. The resulting ability to continuously update the patient model may provide surgeons with a more precise understanding of the current anatomical state and paves the way toward a digital twin paradigm for sinus surgery.

Nasal obstruction is the subjective perception and objective state of insufficient airflow through the nose. Nasal congestion, conversely, describes a state of not just inadequate airflow or obstructive phenomena but also pressure- and mucus-related states to the patient. Nasal receptors belonging to the transient receptor potential (TRP) protein family mediate the sense of nasal patency via the trigeminal nerve. The transient receptor potential melastatin-8 (TRPM8) responds to temperatures around 8°C to 22°C, and is stimulated by menthol and other cooling agents. The radiant effects of airflow create heat loss to activate these receptors and humans perceive this as nasal patency rather than the direct detection of airflow. The thermovascular state of the mucosa, in conditions such as rhinitis, influence TRPM8 activation. Nasal endoscopy can show signs of rhinitis and should be considered an essential part of the workup of nasal congestion. Efforts to relieve nasal congestion need to manage the mucosal state and surgery needs to ensures that the nasal cavity mucosa is exposed to the cooling effects of airflow rather than simply creating a passage to the nasopharynx.

UNASSIGNED: Dural sinus thrombosis is considered as a one of the clinical and radiological emergencies that require special attention and high index of suspicion and needs combined effort of both the treating physician and the radiologist to obtain proper diagnosis and subsequently proper management.
UNASSIGNED: The aim of this article was to compare the accuracy of MRV TOF and post contrast MP-RAGE sequences in diagnosis of cerebral sinus venous thrombosis.

Conclusion: The results for T2 WI, SWI, MRV TOF and MP-RAGE post contrast were reported. We used a confidence level score to standardize the results. Then the results were analyzed using simple statistical methods.

Introduction The advent of social media platforms, notably TikTok, has significantly transformed the landscape of health information dissemination, offering both opportunities and challenges for public health communication. This study focuses on TikTok\'s influence on sinus health information, addressing the dual challenge of widespread engagement and the risk of misinformation in otolaryngology, or ENT (ear-nose-throat), information online. We introduce the ENT Content Engagement and Quality Index (ENT-CEQI), a pioneering tool designed to assess the quality and engagement of ENT-related content on TikTok, aiming to improve public understanding of sinus health. Materials and methods Our methodology involved a systematic analysis of sinus health-related content on TikTok. We collected data on the top 100 most popular videos using the hashtag #sinus at two different points in time, analyzing engagement metrics and content quality. The ENT-CEQI was developed to evaluate content, incorporating both quantitative engagement metrics (views, likes, comments, shares, favorites) and qualitative assessments (accuracy, clarity, relevance, practicality, engagement). The study employed statistical analyses, including trend analysis, correlation analysis, principal component analysis (PCA), KMeans clustering, regression analysis, and the Kruskal-Wallis test, to understand the dynamics of content engagement and quality. Results Initial findings revealed significant disparities in engagement metrics and quality scores among different content creator categories, with physician-generated content showing the highest engagement and quality. The trend analysis indicated shifts in content popularity and quality over time, with a notable increase in views and likes for private company content. The PCA and clustering analyses identified distinct content clusters, offering insights into viewer engagement patterns. Regression analysis and the Kruskal-Wallis test, however, did not find significant predictors (p-value: 0.3916) of content quality or differences in likes across content types, suggesting complex factors influencing content engagement and quality perception. Discussion The study highlights TikTok\'s potential and pitfalls in disseminating sinus health information. The introduction of the ENT-CEQI represents a major step toward enhancing the evaluation of health content on social media, emphasizing the importance of accuracy, clarity, and relevance in public health communication. The analysis underscores the complexity of social media engagement and the need for robust tools to assess content quality. It also points to the critical role of healthcare professionals in engaging with the public through social media to combat misinformation. Conclusions TikTok serves as a potent platform for sinus health education, capable of reaching wide and diverse audiences. The ENT-CEQI emerges as a vital tool for assessing the quality and engagement of ENT-related content, guiding content creators toward producing more reliable and informative content. This study contributes to the understanding of social media\'s role in health communication, advocating for the strategic use of innovative tools such as the ENT-CEQI to enhance public health outcomes through improved online health education and misinformation management.
