Radiomorphometric indices for measuring mandibular bone quality in oncologic patients.

Objective: This retrospective study compared the thickness and degree of resorption of the mandibular cortex in patients with head and neck cancer (AG), patients with cancer at sites other than the head and neck (BG), and patients with no cancer (CG) to describe and compare the changes in the mandible after antineoplastic therapy and their possible clinical implications.

Materials And Methods: A total of 287 panoramic radiographs were examined. The following radiomorphometric indices were analyzed: mental index (MI), panoramic mandibular index (PMI), and mandibular cortical index (MCI).

Dolichocarpols G-X: Previously undescribed macrocyclic humulene sesquiterpenoids from Anaxagorea dolichocarpa.

Eleven previously undescribed macrocyclic humulene sesquiterpenoids, dolichocarpols G-Q (1-11), five undescribed bicyclic, dolichocarpols R-V (12-16) and two undescribed norsesquiterpenes, dolichocarpols W-X (17-18) were isolated from the roots of Anaxagorea dolichocarpa. Their structures were unequivocally determined by the analysis of NMR, HRESIMS, and IR data, along with NMR and ECD quantum-mechanical calculations, followed by the application of the DP4+ method. Most compounds possess an ether bridge between different carbons, whereas compounds 13/14 and 15/16 are diastereomers isomerized at C-7/C-10 and at C-7/C-10/C-12, respectively.

Oral and Maxillofacial Manifestations of Kallmann Syndrome: A Systematic Analysis of the Literature.

Aims: Kallmann syndrome (KS) is a rare genetic disorder characterized by congenital hypogonadotropic hypogonadism and varied clinical features. Despite its recognition, the oral and maxillofacial manifestations remain poorly understood. This study synthesized clinical aspects and management of KS-related oral and maxillofacial alterations.

Four decades of treatment for actinic cheilitis: Outcomes, challenges, and the introduction of a new clinical index.

Objective: To evaluate the clinical outcomes of surgical and non-surgical treatments for actinic cheilitis (AC) over a four-decade period and to introduce a novel Clinical Index for the Treatment and Control of Actinic Cheilitis (CITC-AC) for improved patient stratification and management.

Materials And Methods: A retrospective cohort study analyzed 151 patients diagnosed with AC treated at a university clinic between 1980 and 2020. Sociodemographic, clinical, and histopathological data were collected.

Neck circumference cutoff point as a predictor of metabolic syndrome in Brazilian rural workers.

Neck circumference (NC) is a predictive measure for the diagnosis of Metabolic Syndrome (MS). The aim of the present study was to establish cutoff points for NC as a predictor of the presence of MS in Brazilian rural workers, based on the MS components according to the IDF and NCEP-ATP III criteria. This is a cross-sectional study carried out with rural workers in the municipality of Santa Maria de Jetibá, in the state of Espírito Santo, Brazil.
