Characteristics and prevalence of orofacial pain as an initial symptom of oral and oropharyngeal cancer and its impact on the patient's functionality and quality of life.

Objective: To evaluate the prevalence and characteristics of orofacial pain in oral and oropharyngeal cancer (OOC), at diagnosis.

Material And Methods: a) Study group (SG; n = 74) patients with cancer were divided into 2 subgroups: oral cancer (OC) and oropharyngeal cancer (OPC); b) control group (CG; n = 74) patients within dental care.

Study Design: An Orofacial Pain Assessment, verbal descriptive scale, Helkimo dysfunction index, Quality of Life questionnaire, and Karnofsky performance status (KPS) was used for evaluation.

Lack of direct association between oral mucosal lesions and SARS-CoV- 2 in a cohort of patients hospitalised with COVID-19.

Background: COVID-19 is a disease affecting various human organs and systems, in which the virus seeks to interact with angiotensin-converting enzyme 2 receptors. These receptors are present in the oral cavity, but the direct relationship between such an interaction and possible oral manifestations of COVID-19 is still unclear.

Aim: The present study evaluated oral manifestations in a cohort of COVID-19 patients during the period of hospitalisation.

Temporomandibular joint arthritis in sickle cell disease: a case report.

We report a rare case of aseptic arthritis in the temporomandibular joint of a patient with sickle cell anemia. A 22-year-old woman with sickle cell disease, in the 18th week of gestation, was referred by her hematologist to investigate a sudden mouth opening limitation and severe pain on her left cheek. The patient received a standard pain assessment protocol, clinical examination, and complementary exams (complete blood count, hemoglobin electrophoresis, blood solubility test, panoramic radiograph, and magnetic resonance imaging [MRI]).

A known SOST gene mutation causes sclerosteosis in a familial and an isolated case from Brazilian origin.

Sclerosteosis is a severe, rare, autosomal recessive bone condition that is characterized by a progressive craniotubular hyperostosis. The main features are a significant sclerosis of the long bones, ribs, pelvis, and skull, leading to facial distortion and entrapment of cranial nerves. Clinical features include a tall stature, nail dysplasia, cutaneous syndactyly of some fingers, and raised intracranial pressure.

Treatment of obstructive sleep apnea syndrome in patients from a teaching hospital in Brazil: is it possible?

Objective: The aim of this study was to evaluate the efficacy of a cost-effective intra-oral appliance for obstructive sleep apnea syndrome built into a large teaching hospital.

Materials And Methods: Out of 20 evaluated and treated patients, 14 concluded the study: eight men and six women, with a mean age of 42-46 (mean + SD) years and mean body mass index of 27.66.
