Advances in the Management of HPV-Related Oropharyngeal Cancer.

Patients with human papillomavirus- (HPV-) related oropharyngeal squamous cell carcinoma (OPSCC) have a better prognosis than HPV-negative OPSCC when treated with standard high-dose cisplatin-based chemoradiotherapy. Consistent with this assertion and due to younger age at diagnosis, novel approaches to minimize treatment sequelae while preserving survival outcomes become of paramount importance. Here, we critically reviewed the evidence-based literature supporting the deintensification strategies in HPV-related OPSCC management, including radiotherapy dose and/or volume reduction, replacement of cisplatin radiosensitising chemotherapy, and the use of transoral surgery.

Immune check-point in glioblastoma multiforme.

Glioblastoma multiforme (GBM) represents one of the main frequent and aggressive primary brain neoplasms among adults worldwide. Despite a first-line multimodal treatment, including radical surgery and adjuvant radiation therapy with concomitant temozolomide-based chemotherapy, GBM prognosis continues to be unfavourable. During this decade, different research groups have explored immune check-point inhibitors role in order to improve response to therapy and subsequently prolong survival rate.

Obstructive sleep apnea syndrome in the pediatric age: the role of the dentist.

Objective: Sleep disordered breathing in children designates a wide spectrum of respiratory disorders characterized by partial or complete obstruction of the upper airways. It ranges from primary snoring, its mildest clinical manifestation, to obstructive sleep apnea syndrome (OSAS): complete obstruction of the upper airways with cessation of airflow. The aim of this paper is to highlight the roles of the pediatric dentist and the orthodontist in the therapeutic approach to pediatric OSAS as a "sentinel" who can detect early signs of the disease for immediate referral to the otolaryngologist and as an active participant in therapy.

Regenerative Endodontic Procedures Using Contemporary Endodontic Materials.

Calcium hydroxide apexification and Mineral Trioxide Aggregate (MTA) apexification are classical treatments for necrotic immature permanent teeth. The first tend to fail for lack of compliance given the high number of sessions needed; the second has technical difficulties such as material manipulation and overfilling. With both techniques, the root development is interrupted leaving the tooth with a fragile root structure, a poor crown-to-root ratio, periodontal breakdown, and high risk of fracture, compromising long-term prognosis of the tooth.

Dental Cone Beam Computed Tomography in Children: Clinical Effectiveness and Cancer Risk due to Radiation Exposure.

Firstly used in the early 90s to generate 3-dimensional projections of X-ray images, cone beam computed tomography (CBCT) has resulted in a large application in dentomaxillofacial imaging, even in children. CBCT uses ionizing radiation that may cause damage to the DNA, and children are at the greatest carcinogenesis risk due to their higher tissue radiosensitivity and their longer life expectancy compared to adults. The questions of whether the cancer risk is really increased after repeated dental CBCT in childhood and of what the underlying biological basis is have become hot topics in the field of dentistry and radiobiology.

Oral Plaque from Type 2 Diabetic Patients Reduces the Clonogenic Capacity of Dental Pulp-Derived Mesenchymal Stem Cells.

Type 2 diabetes (T2D) is a major metabolic disease and a key epigenetic risk factor for the development of additional clinical complications. Among them, periodontitis (PD), a severe inflammatory disease ascribable to a dysregulated physiology and composition of the oral microbiota, represents one of the most relevant complications. Periodontitis can impact the structure of the tooth and likely the stem and progenitor cell pool, which actively contributes to the periodontal microenvironment and homeostasis.

Additive manufacturing and biomimetic materials in oral and maxillofacial surgery: a topical overview.

Additive manufacturing (AM) is the term used for different and complex techniques to manufacture products with complex morphology, often referred to as "custom-made". The product is made without needing to melt the material into pre-formed molds, nor to remove it from an initial mass, as happens in subtractive processes. The additive methodology gives the AM enormous potential in the widest fields of application, from aerospace to biomedical, from dental to maxillofacial.

Predictors of stent thrombosis and their implications for clinical practice.

Stent thrombosis (ST) is a rare but severe complication of coronary procedures with high mortality, high relapse rate and a very complex pathophysiology. An individual's susceptibility to ST is multifactorial and results from interactions between clinical factors, endothelial biology, hypersensitivity and/or inflammatory reactions, blood rheology, platelet reactivity, clotting factors, physical and mechanical properties of the stent and from the effects of these different factors on the fluid dynamics of blood flow. Since the introduction of stents 32 years ago, continuous improvements in our understanding of the pathophysiology of ST have triggered important advances, including new therapies, new technologies and an increased awareness of the implications of implantation techniques.
