Head and neck cancer is a heterogeneous disease, originating in the squamous cells lining the larynx (voice box), mouth, pharynx (throat), nasal cavity and salivary glands. Head and neck cancer diagnosis at the later stage is greatly influencing the survival rate of the patient. It makes a mandatory situation to identify this cancer at the earlier stages of development with a suitable biomarker. Squamous cell carcinoma antigen (SCC-Ag) is a circulating serum tumour biomarker, and the elevated level has been found in the head and neck cancer patients and highly correlated with the tumour volume. The present research was carried out to detect and quantify the level of SCC-Ag on titanium oxide (TiO)-modified interdigitated electrode sensor (IDE) by SCC-Ag antibody. The detection of SCC-Ag was found at the level of 100 fM, while it was improved to 10 fM when the antibody was conjugated with gold nanostar, representing a 10-fold improvement. Interestingly, this enhancement in sensitivity is 1000-folds higher than other substrates. Moreover, the specificity analysis was carried out using two different control proteins and noticed that the antibody only recognised SCC-Ag, indicating the specific detection on IDE-TiO sensing surface.

Introduction: The nasoseptal flap (NSF) has become a widely favoured choice for reconstructing skull base defects following the endoscopic endonasal approach (EEA). However, the exposed septal cartilage and bone at the donor site often require an extended duration for secondary healing. This study investigated whether the free middle turbinate (MT) mucosa grafting at the septal donor site could mitigate post-operative nasal morbidity.

Objectives: Cutaneous adnexal carcinomas (CACs) are rare skin cancers with no established treatment guidelines. Given the limited data, this study aims to explore the characteristics and outcomes of patients with CAC treated with radiation therapy (RT).
Methods: Patients diagnosed with CAC between 2000 and 2020 who received RT were included.

Background: This study aimed to investigate and analyze the current status of oral disease treatment among the older adult in Guangxi Zhuang Autonomous Region, while also assessing the continuing medical education (CME) needs of dental institution personnel regarding oral diseases in this population.
Methods: Convenience sampling was used to investigate the oral disease treatment among older adults and to assess CME needs of dental institution personnel regarding oral diseases in this population across various oral medical and health institutions in Guangxi.
Results: A total of 754 valid questionnaires were collected, of which 70.

Objective: To investigate the influencing factors of inpatients giving red packets to doctors and explore the necessity of doctor-patient red packet agreements.
Methods: A questionnaire survey was conducted among inpatients and their families who were hospitalized in several hospitals in Chengdu from January to June 2023. The survey asked about the patients' (or their families') attitudes and opinions on whether it was necessary to give red packets to doctors during hospitalization.

Chronic rhinosinusitis (CR) is a persistent inflammation of the nasal mucosa and paranasal sinuses. Endoscopic sinus surgery (ESS) is a procedure that improves sinus drainage and ventilation. Despite advancements in ESS, additional corrective procedures post-ESS are often needed.
