Objective: Neural integrity monitoring (NIM) endotracheal tubes are widely used to provide intraoperative monitoring of the recurrent laryngeal nerve during certain neck surgeries, especially thyroidectomy, in order to reduce the risk of nerve injury and subsequent vocal fold paralysis. The unique design of NIM tubes and the increased technical skill required for correct placement compared to standard endotracheal tubes may increase the risk of upper aerodigestive tract soft tissue injury. This study aims to describe adverse events related to NIM endotracheal tubes.

Study Design: Retrospective cross-sectional study.

Setting: The US Food and Drug Administration's MAUDE database (2010-2022); (Manufacturer and User Facility Device Experience).

Methods: The MAUDE database was queried for reports of adverse events that resulted in patient soft tissue injury involving the use of endotracheal tubes approved by the Food and Drug Administration.

Results: There were 28 reported soft tissue injuries, with all events being related to the NIM EMG family of endotracheal tubes manufactured by Medtronic Xomed, Inc. Overall, 24 were categorized as device-related adverse events, and 4 were unspecified in the event description. The most common soft tissue injuries were edema (n = 7) and perforation (n = 7), each accounting for 25 % of adverse events. The second most common injury type was laceration (n = 4), representing 14 % of all adverse events. Overall, 9 patients (32 %) in our cohort required a surgical intervention to treat their injuries, which consisted of 6 tracheotomies and 3 instances of suture repair.

Conclusions: The most commonly reported types of soft tissue injury included edema and perforation, followed by laceration. Increased awareness of device-related patient injuries associated with NIM endotracheal tubes can be used to better inform surgeons and anesthesiologists during the process of intubation and surgical decision-making.

Objective: The aim of the current study was to examine possible associations between gingival thickness and other parameters, such as crown length and width, papilla height and patient's age and gender.

Overview: This cross-sectional study included 238 consecutive white Caucasian consecutive patients in all stages of orthodontic treatment (before, in-course, and after orthodontic treatment). Measurements of gingival thickness were carried out at both central mandibular incisors, mid-facially on the buccal aspect of each tooth, and 2 mm apically to the free gingival margin, with an Ultrasound device.

After tooth extraction, alveolar bone absorbs unevenly, leading to soft tissue collapse, which hinders full regeneration. Bone loss makes it harder to do dental implants and repairs. Inspired by the biological architecture of bone, a deformable SIS/HA (Small intestinal submucosa/Hydroxyapatite) composite hydrogel coaxial scaffold was designed to maintain bone volume in the socket.

The detection of skeletal remains using human remain detection dogs (HRD) is often reported anecdotally by handlers to be a challenge. Limited studies have been conducted to determine the volatile organic compounds (VOCs) emitted from bones, particularly when there is limited organic matter remaining. This study aimed to determine the VOCs emitted from dry, weathered bones and examine the detection performance of HRD dogs on these bones when used as training aids.

Abstract: Diabetic foot ulcer (DFU) is a severe complication of diabetes. Due to conservative or delayed treatment, the majority of DFU patients frequently miss the optimal treatment window, thereby leading to amputation. Despite being a rare pathogen with low virulence, () exhibits some antibiotic resistance and can be fatal for immunocompromised patients.

Persistent anterolateral ankle pain is a debilitating condition often associated with soft tissue impingement following inversion injuries. It can lead to significant limitations in daily activities and overall quality of life, particularly in individuals with chronic ankle instability. This systematic review examines the efficacy and safety of minimally invasive arthroscopic decompression techniques in managing anterolateral ankle impingement syndrome.
