RESUMO
Background: The 8th edition of the American Joint Committee on Cancer (AJCC) classification has introduced two new parameters: depth of invasion (DOI) and extranodal extension (ENE). The aim of this systematic review was to determine whether this 8th edition referred to oral squamous cell carcinoma (OSCC) offers performance superior to that of the 7th edition in relation to overall survival (OS) and disease-specific survival (DSS). Material and Methods: The review was carried out following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The PubMed (MEDLINE), Scopus and Cochrane Library databases were searched covering the period up until April 7th, 2022.Results: Thirteen retrospective cohort studies were finally included. The introduction of DOI and ENE in the 8th edition of the AJCC classification resulted in improved prognostic performance of the classification. Conclusions: Patients with OSCC can be better classified in relation to OS and DSS, while maintaining the simplicity and ease of use of the classification. This allows more appropriate treatment protocols to be applied and affords a better estimation of the prognosis of each patient.(AU)

BACKGROUND: Previous studies have evaluated the implementation of behavioral approaches in individuals with chronic temporomandibular disorders (TMDs). OBJECTIVE: To evaluate the benefits of a behavioral approach to craniofacial pain. Second, we assessed the benefits of kinesiophobia, catastrophizing, mouth opening without pain, and forward head posture. METHODS: Individuals with chronic TMDs were treated for five weeks. The intervention group (n = 17) underwent pain neuroscience education, manual therapy, and therapeutic exercise, whereas the control group (n = 17) underwent manual therapy only. Outcomes were evaluated immediately, at seven and 19 weeks follow-up. The assessment tools used were the Craniofacial Pain Disability Inventory, Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, Mandibular Range of Motion Scale, and Cervical Range of Motion Tool. RESULTS: The interventions did not influence the differences in the improvements between the groups observed for craniofacial pain disability (inter-subject p 0.4). The intervention had a moderate influence on the improvement of kinesiophobia and catastrophizing (Inter-subject p 0.09 and 0.1 respectively) with a clinically significant effect size (Estimated mean (EM) -8.6 standard deviation (SD) ±3.48 p 0.019; and EM -7.6 SD ± 5.11 p 0.15 respectively). CONCLUSION: The behavioral approach improved catastrophizing and kinesiophobia outcomes in individuals with chronic TMDs.
RESUMO
Background: The primary objective of this study was to determine the position and course of the greater palatine artery using color doppler ultrasound. The secondary objective was to determine the thickness of the palatine fibromucosa. Material and Methods: A pilot case series study was performed in a private clinic during February 2020. The scans were performed with a Mindray® M9 ultrasound machine (Mindray North America, NJ, USA) coupled to an L16-4Hs® hockey-type angled probe. For each participant, the arterial path and thickness of the palatal fibromucosa were determined at 5 different points. Results: A total of 6 volunteers (3 males and 3 females) with a mean age of 39.2 (±16) years were included. While the thickness of the fibromucosa decreased along the anterior area, the distance from the cementoenamel junction to the position of the artery was generally maintained up to the canine position, where it was found to be closed to teeth. Conclusions: Color doppler ultrasound allows accurate localization of the artery as well as measurement of the thickness of the palatine fibromucosa. It would help to select the best area for graft harvesting in order to avoid bleeding complications due to vascular sectioning.
