Impact of the COVID-19 pandemic on the severity of newly diagnosed cases of head and neck cancer in southern Brazil.

This observational study aimed retrospectively assess the impact of the COVID-19 pandemic on the head and neck squamous cell carcinoma (HNSCC) diagnosis and severity of the disease in southern Brazil. All new cases diagnosed with HNSCC from March 11, 2019 to March 10, 2020 (pre-COVID-19) and from March 11, 2020 to March 10, 2021 (COVID-19) were included. The data collected were: date of the histopathological diagnosis, sociodemographic data, place of residence, data related to the tumor (location of the primary tumor, lymph node involvement, distant metastasis and TNM clinical staging), time elapsed between the diagnosis and treatment initiation.

Diagnosis of juvenile idiopathic arthritis with asymptomatic involvement of the temporomandibular joint: A case report.

Juvenile idiopathic arthritis (JIA) is a broad term that describes a group of heterogeneous rheumatologic diseases, mainly characterized by inflammation in the joints of children and young people up to 16 years of age. Its etiology is still not well understood and the diagnosis, essentially clinical, begins with the exclusion of other joint diseases. When the disease affects the temporomandibular joint, diagnosis is a challenge, as many patients are asymptomatic.

Association between tamoxifen and tooth loss in women with breast cancer.

Objectives: Investigate the effect of tamoxifen on the occurrence of tooth loss (TL) in breast cancer (BC) survivors.

Methods: A cross-sectional study was conducted with 140 BC survivors using tamoxifen therapy. Sociodemographic, medical, and dental data were evaluated.

Late radiation effects in survivors of head and neck cancer: State of the science.

Head and neck squamous cell carcinoma is one of the most common neoplasms. Radiotherapy (RT) plays an essential role in the management of such cases. Despite advances in the technique, hyposalivation, xerostomia, dysphagia, trismus, radiation caries, and osteoradionecrosis remain significant late complications of RT.

Prevalence of hyposalivation and associated factors in survivors of head and neck cancer treated with radiotherapy.

Unlabelled: Hyposalivation and sensation of dry mouth (xerostomia) are one of the most common adverse effects in the treatment of patients with head and neck cancer.

Objective: This study evaluates the prevalence of late hyposalivation and associated factors in survivors of squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx treated with radiotherapy with or without concomitant chemotherapy.

Methodology: A cross-sectional study was conducted with 88 patients who had concluded radiotherapy at least three months before the study, at a referral center for the treatment of head and neck cancer in the Southern region of Brazil.

Effect of the sense of coherence and associated factors in the quality of life of head and neck cancer patients.

The sense of coherence (SOC) is a measure of global orientation regarding the ability of individuals to cope with stressful situations. The aim of the present study was to evaluate the association between SOC and quality of life (QoL) and clinical and sociodemographic characteristics among survivors of oral, oropharynx, hypopharynx, or larynx cancer. A cross-sectional study was conducted with 90 cancer patients in follow up at the Santa Maria University Hospital in southern Brazil who had completed conformal 3D radiotherapy at least three months earlier.

Clinical and sociodemographic factors that affect the quality of life of survivors of head and neck cancer.

Objective: The present cross-sectional study evaluated the quality of life of patients treated with 3-D conformal radiotherapy for cancer of the mouth, oropharynx, hypopharynx, or larynx and investigated possible associations with clinical and sociodemographic variables using multivariate analysis.

Methods: The sample was composed of 90 patients who had completed treatment at least 3 months earlier. Data were collected from April 2016 to May 2017.

Association between trismus and dysphagia-related quality of life in survivors of head and neck cancer in Brazil.

Objectives: The aim of this study was to evaluate the association between trismus and other radiation-associated conditions with dysphagia-related quality of life in patients who have undergone radiotherapy of the head and neck.

Study Design: This cross-sectional study included 88 patients who had squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx, or larynx and had been treated with 3-dimensional (3-D) conformal radiotherapy, which had been completed at least 3 months earlier. Clinical data were obtained from medical records.

Study of Pathological Changes in the Dental Follicle of Disease-Free Impacted Third Molars.

Background: The prophylactic extraction of third molars is a common practice in dental offices, but divergent opinions are found in the literature regarding the indication of this procedure. The aim of the present study was to determine the prevalence of pathological changes associated with the pericoronal tissue of asymptomatic impacted third molars that could justify prophylactic extraction.

Materials And Methods: A cross-sectional observational study was conducted in which 109 pericoronal tissues with no radiographic evidence of pathology were histopathologically analyzed.

Apicotomy as treatment for failure of orthodontic traction.

Objective. The purpose of this study was to present a case report that demonstrated primary failure in a tooth traction that was subsequently treated with apicotomy technique. Case Report.

Craniofacial and dental manifestations of triple X syndrome associated with congenital hypothyroidism: a case report.

Triple X syndrome (47,XXX) is a numerical chromosomal alteration that affects 1/1,000 women, in which the woman is born with an extra X chromosome. Some oral changes have been reported in the literature, as hypodontia, influence on deposition of crown enamel and discrepancies in cephalometric measurements. Other systemic complications may lead to oral abnormalities similar to those seen in triple X patients, such as congenital hypothyroidism (CH).

Galectin-3 immunoprofile in adenoid cystic carcinoma and polymorphous low-grade adenocarcinoma of salivary glands.

Adenoid cystic carcinoma (ACC) and polymorphous low-grade adenocarcinoma (PLGA) are malignant neoplasms of salivary glands, which are similar in histologic patterns but very different in clinical behavior, treatment and prognosis. Galectin-3 is a multifunctional protein of a growing family of beta-galactoside-binding animal lectins, which is implicated in a variety of biological events such as tumor cell adhesion, proliferation, differentiation and angiogenesis. This protein was found to be implicated in cellular transformation and a correlation between its expression and cancer progression and metastasis has been described.
