Screening Awareness of HPV-Related Oropharyngeal Cancers and Attitudes and Concerns towards HPV Vaccination Among Parents : HPV and Oropharyngeal Cancer.

Baseline population opinions on human papillomavirus (HPV) and HPV vaccination must be understood before physicians can address knowledge gaps in that population and encourage timely vaccination. To determine the opinions of parents of children age 9 to 18 on HPV-related oropharyngeal cancers (OPC); the associations with education level, socioeconomic status, and having a family member/friend with OPC; and the main concerns against having a vaccination., An anonymous survey was created and administered.

Hit-to-lead optimization on aryloxybenzamide derivative virtual screening hit against SIRT.

Sirtuins (SIRTs) are a class of nicotinamide adenine dinucleotide (NAD)-dependent protein histone deacetylases (HDACs) that are evolutionarily conserved from bacteria to mammals. This group of enzymes catalyses the reversible deacetylation of lysine residues in the histones or non-histone substrates using NAD as a cosubstrate. Numerous studies have demonstrated that the aberrant enzymatic activity of SIRTs has been linked to various diseases like diabetes, cancer, and neurodegenerative disorders.

Chronic Pain Management in Head and Neck Oncology.

Pain is epidemic in patients with head and neck cancer. Providers involved in the care of patients with head and neck cancer should be able to describe the common pain syndromes experienced by these patients, identify patients at risk of pain, and provide multimodal treatment of chronic pain. Treatment of chronic pain encompasses analgesic medications; adjuvant pharmacotherapy, including antidepressants and anticonvulsants; interventional techniques; as well as integrative medicine.

Antiepileptic drugs as prophylaxis for postcraniotomy seizures.

Background: This is an updated version of the Cochrane Review previously published in 2018. The incidence of seizures following supratentorial craniotomy for non-traumatic pathology has been estimated to be between 15% to 20%; however, the risk of experiencing a seizure appears to vary from 3% to 92% over a five-year period. Postoperative seizures can precipitate the development of epilepsy; seizures are most likely to occur within the first month of cranial surgery.
