Oral epithelium response of electronic cigarette users to electronic cigarette.

Background: Electronic cigarettes are increasing in popularity, but there is only little information on their biologic effects on the oral epithelium, the initial site exposed to electronic cigarette smoke.

Methods: We assessed the oral epithelium response to electronic cigarettes by comparing the histology and RNA transcriptome (mRNA and miRNA) of healthy electronic cigarette vapers to nonsmokers. mRNA was assessed based on: (1) genome-wide; (2) genes previously identified as dysregulated in the oral epithelium of electronic cigarette vapers versus nonsmokers; (3) immune and inflammatory-related genes previously identified as dysregulated in the nasal epithelium of electronic cigarette vapers compared to nonsmokers; (4) genes previously identified as dysregulated in the small airway epithelium of nonsmokers following an acute exposure to electronic cigarette; and (5) genes related to the initial steps of COVID-19 infection.

Protecting the tracheal tube cuff: a novel solution.

We describe the successful insertion of a nasotracheal tube following repeated cuff rupture. The patient was a 55-year-old woman with a history of nasal trauma and multiple rhinoplasties, who underwent elective Lefort I osteotomy and bilateral sagittal split osteotomy for correction of skeletal facial deformity. During fiberoptic bronchoscope-guided nasal intubation after the induction of general anesthesia, the tracheal tube repeatedly ruptured in both nares, despite extensive preparation of the nasal airways.

Early Clinical Outcomes of Arthroscopic Management of the Failing Alloplastic Temporomandibular Joint Prosthesis.

Purpose: Total joint replacement is the recommended treatment for end-stage temporomandibular joint (TMJ) disease. The goal of treatment is to help the return to acceptable function with improvement of the maximum incisal opening (MIO) and a reduction of pain. When a prosthetic joint shows late complications, surgical management includes an open approach, with debridement, cultures, and prosthetic replacement as options.

Endovascular preoperative embolization for temporomandibular joint replacement surgery.

Background And Purpose: This retrospective study evaluates the safety and effectiveness of preoperative endovascular embolization in patients who underwent temporomandibular joint (TMJ) replacement surgery.

Material And Methods: We included all patients treated with preoperative embolization of the internal maxillary artery (IMAX) between June 2016 and January 2019. All patients were treated by the same surgeon using standard surgical approaches and procedures.

Minimally Invasive Treatment of Temporomandibular Joint Ankylosis and Fibrosis of Temporalis Muscle.

A case of severe mandibular hypomobility due to fibrosis of the left temporalis tendon, combined with ankylosis of the temporomandibular joint, is presented. This case emphasizes the importance of reconstructing the historical timeline to establish a correct diagnosis, ultimately leading to appropriate treatment. The use of minimally invasive surgical techniques and the importance of postoperative rehabilitation are emphasized.

Rationale for early versus late intervention with arthroscopy for treatment of inflammatory/degenerative temporomandibular joint disorders.

Purpose: The goal of this study was to determine if there were differences in outcomes of arthroscopic surgery in patients with inflammatory/degenerative temporomandibular joint (TMJ) disease who underwent early surgical intervention versus late surgical intervention.

Materials And Methods: The study population included 44 consecutive patients who met the criteria for TMJ operative arthroscopy who were divided into early and late intervention groups. The time between the onset of symptoms and the performance of arthroscopy was used to determine entry into the early versus late intervention group.

Oral ectomesenchymal chondromyxoid tumor: case report and literature review.

Ectomesenchymal chondromyxoid tumor (ECMT) of the oral cavity is a rare lesion. We describe the 33rd reported case in the current English-language literature. This patient had originally presented 5 years earlier with a tongue neoplasm with biopsy results consistent with nerve sheath myxoma.

Dental premedication protocols for patients with knee and hip protheses.

In 1997, the American Dental Association (ADA) and the American Academy of Orthopaedic Surgeons (AAOS) published an advisory statement regarding antibiotic prophylaxis for patients with total joint replacements undergoing dental treatment. The first periodic update of these guidelines was published in 2003. Nevertheless, confusion exists among dentists and physicians as to the clinical indications for premedication in this patient population.

The relationship between temporomandibular joint synovitis and adhesions: pathogenic mechanisms and clinical implications for surgical management.

Purpose: The purpose of this investigation was to determine the relationship between arthroscopically diagnosed synovitis and adhesions in a population of patients with significant limitation of mandibular opening and temporomandibular joint pain.

Patients And Methods: Temporomandibular joint arthroscopy was performed on 126 joints in 80 patients (female:male = 5.7:1; mean age = 35.

Tongue entrapment in an aluminum juice can.

Tongue entrapment in bottles and cans is rare, but occurs. The following is a case report of a 10-year-old female who got her tongue entrapped in an aluminum juice can. The anatomy of the tongue, complications from injury, and a proposed removal procedure are described.
