Background: The purpose of this study was to evaluate active surveillance strategy in the clinically negative neck in maxillary squamous cell carcinoma (SCC).
Methods: One hundred fourteen consecutive patients diagnosed with oral maxillary SCC were analyzed retrospectively from 3 centers in The Netherlands. Analysis parameters included regional disease-free survival of N0 patients stratified for T classification, elective radiotherapy (RT) of the neck; and overall survival of the whole cohort, stratified by N classification; salvage neck surgery rates.
Results: Within the N0 cohort, 26.0% of the patients developed neck metastasis in the follow-up visits. Regional recurrence was not related to T classification or postoperative RT of the neck. Regional and locoregional recurrence were associated with diminished overall survival (p < .05). Regional metastasis was operable in 22 of 26 cases (85%). Only 1 patient presented with inoperable neck metastasis without local recurrence.
Conclusion: Watchful waiting was feasible in this cohort. If meticulous follow-up is not available, elective neck dissection is recommended. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1794-1798, 2016.

The Third Ward of Orthopaedic Department, General Hospital of Ningxia Medical University, 804 Shengli South Street, Hui Autonomous Region, Yinchuan, Ningxia, 750004, People's Republic of China.
The purpose of this study is to assess the safety and effectiveness of TiRobot-assisted treatment for femoral neck fractures, in comparison to traditional freehand treatment methods. Throughout the research process, we conducted an extensive literature search across numerous databases, including PubMed, EMBASE, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), CQVIP, and Wanfang. Based on the literature screening criteria, we selected six studies, encompassing 358 cases of femoral neck fracture patients, for this meta-analysis.

Introduction: Laryngeal chondrosarcoma (CS) is a rare indolent malignant tumor. High-grade (G3), dedifferentiated (DD), and myxoid (MY) CSs are considered more aggressive subtypes due to their metastatic potential and relatively poor outcomes. The aim of this systematic review is to evaluate treatment modalities and survival outcomes in patients affected by these rarer CS subtypes.

Objective: To compare the treatment of osteoradionecrosis (ORN) using a protocol that incorporates antimicrobial photodynamic therapy with a conventional treatment protocol.
Methodology: This retrospective study analyzed 55 patients diagnosed with ORN at a reference hospital between 2002 and 2021. Patients were treated using two different clinical protocols.
Genetic landscape in undiagnosed patients with syndromic hearing loss revealed by whole exome sequencing and phenotype similarity search.

Division of Hearing and Balance Research, National Institute of Sensory Organs, NHO Tokyo Medical Center, 2-5-1 Higashigaoka, Meguro-Ku, Tokyo, 152-8902, Japan.
There are hundreds of rare syndromic diseases involving hearing loss, many of which are not targeted for clinical genetic testing. We systematically explored the genetic causes of undiagnosed syndromic hearing loss using a combination of whole exome sequencing (WES) and a phenotype similarity search system called PubCaseFinder. Fifty-five families with syndromic hearing loss of unknown cause were analyzed using WES after prescreening of several deafness genes depending on patient clinical features.

Objective: This study aims to investigate the genetic link between psoriasis and sudden sensorineural hearing loss (SSNHL).
Methods: From a genetic standpoint, this study further highlighted the connection between psoriasis and SSNHL. Single nucleotide polymorphisms (SNPs) connected to SSNHL could be found using a genome-wide association study from the IEU OpenGWAS project website.
