Quality of Life of Patients After Treatment for Cancer in the Head and Neck Region: A Case-Control Study.

Introduction: It is known that side effects caused by antineoplastic therapy can affect patients' quality of life (QOL). However, the long-term effects on patients' quality of life are not well known. This study aimed to evaluate patients' quality of life who underwent radiotherapy for head and neck cancer lasting more than six months compared to individuals who did not experience treatment.

Hepatitis delta virus interacts with splicing factor SF3B155 and alters pre-mRNA splicing of cell cycle control genes.

Hepatitis delta virus (HDV) is the agent responsible for the most severe form of human viral hepatitis. The HDV genome consists of a single-stranded circular RNA molecule that encodes for one single protein, the delta antigen. Given its simplicity, HDV must make use of several host cellular proteins to accomplish its life cycle processes, including transcription, replication, post-transcriptional, and post-translational modifications.

Atypical angiofibroma in a patient with compromised general health: A case report.

Introduction: The nasopharyngeal angiofibroma (NA) is a benign tumor that originates from the pterygopalatine fossa and extends to the adjacent anatomical structures and affects frequently young individuals. The basic treatment for NA is surgical resection, but in some cases the tumor is surgically inaccessible.

Case Presentation: We describe the case of a 45-year-old male with respiratory difficulty after the appearance of a soft palate lesion.

Reconstruction of the Parotid Duct.

The most common causes of parotid duct lesions are injuries with sharp instruments. Late alterations after such lesions lead to esthetic defects and complicates the treatment. This case report presents an alternative surgical technique for late reparation of the parotid duct.
