    Anatomical Bases of the Temporal Muscle Trigger Points
    (2024) GARRIDO, Luis Carlos Fernandez; SIMONETTI, Giulianna; SALEH, Samir Omar; HOJAIJ, Flavio; ANDRADE, Mauro; JACOMO, Alfredo Luiz; AKAMATSU, Flavia Emi
    Background and Purpose. Myofascial pain syndrome (MPS) is a chronic or acute form of musculoskeletal pain that affects nearly three-quarters of the world's population. It is characterized by muscle pain and stiffness, with palpable nodules and hyperirritability areas called myofascial trigger points (MTPs). The temporal muscle is frequently involved in MPS, and four MTPs in the temporal muscle have been described in the literature, but no anatomical description of the MTPs has been reported. The present study described the entry points of deep temporal nerves in the temporal muscle belly and related these points to the MTPs described in the literature. Method. Temporal muscles of 14 adult cadavers were studied. The muscle bellies were divided into six areas, three superior (1.2 and 3) and three inferior areas (4, 5, and 6) lower, according to a Cartesian plane to analyze and describe the entry points of the branches of the deep temporal nerves into the muscle. The branching distribution was analyzed using Poisson log-linear tests with Bonferroni post hoc tests for comparison between groups (sextants) (p<0.05). Results. Deep temporal nerve entry points were found in the temporal muscle in all areas. Most of the branches were observed in areas 2 and 5, which coincide with the muscle fibers responsible for mandible elevation and related to the previously described MTPs. Fewer branches were found in areas 1 and 6, where contraction produces mandible retraction. Conclusion. There is an anatomical correlation between the branching pattern of the deep temporal nerve and temporal muscle trigger points. Adequate knowledge of the innervation of the temporal muscle may help elucidate the pathophysiology of myofascial syndromes and provide a rational basis for interventional or conservative approaches and help surgeons avoid iatrogenic lesions to the deep temporal nerve lesion.

    Active surveillance of papillary thyroid carcinoma in Latin America: a scoping review
    (2024) MANFIO, Pedro Garnier; CHINELATTO, Lucas Albuquerque; HOJAIJ, Flavio Carneiro
    Thyroid nodules are a very common finding and have a malignancy rate of 7%-15%. Some malignant nodules have an indolent behavior and may not affect mortality if left untreated. Active surveillance (AS) is a strategy to prevent overtreatment in patients with papillary thyroid microcarcinomas (PTMCs). This review was conducted to evaluate the status of AS for low-risk PTMC in Latin America, including cultural and logistical challenges, disease progression data, and financial viability. We searched PubMed (MEDLINE), SciELO, LILACS, and Web of Science for articles published after 2014 and enrolling adult Latin American patients. Articles cited in the selected studies were also retrieved. We analyzed the AS protocols, technical or logistical challenges, patient adherence, reasons for AS interruption, surgical conversion rates, duration of AS, and disease progression during AS in our region. Three articles were included in the analysis, all of which considered AS a viable option and reported tumor progression and outcomes similar to those reported in other countries. Neck ultrasound and serum levels of thyroglobulin, thyroid-stimulating hormone (TSH), thyroxine (T4), and antithyroglobulin antibodies were included in the follow-up. No cases of new distant metastases were reported, and the outcomes were favorable when surgery was required. Anxiety was the main reason for AS interruption. We conclude that AS can be an acceptable approach and is safe and effective in Latin America, although more prospective studies are needed to consolidate this strategy in our region. Adequate infrastructure, follow-up, and patient education, as well as multidisciplinary healthcare teams trained in conducting AS must be ensured for successful results.
