<h3>Background</h3> Standard treatment of oropharyngeal squamous cell carcinoma (OPSCC) is associated with high morbidity, whereas immunotherapeutic approaches using PD-1:PD-L1 checkpoint blockade only show moderate response rates in OPSCC patients. Therefore, a better stratification patients and the development novel therapeutic protocols are crucially needed. The importance tumor-infiltrating B cells (TIL-Bs) shaping antitumor immunity remains unclear; therefore, we analyzed frequency,...

Abstract We stratified post-COVID patients into four newly established clinical groups based on the presence or absence of at least one subjective respiratory symptom and objective sign pulmonary involvement. Nearly half outpatients third hospitalized had signs involvement without accompanying symptoms three months after diagnosis.

Central skull-base osteomyelitis (CSBO) represents a life-threatening complication of external ear canal infection. Computed tomography (CT) and magnetic resonance imaging (MRI) play key roles in assessment CSBO progression. Twelve patients with were included retrospective clinical study. In total, 62 scans (30 CTs 32 MRIs) performed to evaluate the extent inflammatory changes. The read independently by two radiologists specialised head neck. regions under skull base specified using online...

Abstract Objective: To identify deep neck infection factors related to life-threatening complications. Methods: This retrospective multi-institutional study comprised 586 patients treated for infections between 2002 and 2012. The statistical significance of variables associated with complications was assessed. Results: During treatment, occurred in 60 out cases. On univariate analysis, were linked to: dyspnoea, movement disturbance dysphonia (all p &lt; 0.001); parapharyngeal, anterior...

MicroRNAs (miRNAs) are non-coding regulatory molecules 18-25 nucleotides in length that act as post-transcriptional regulators of gene expression. MiRNAs affect various biological processes including carcinogenesis. Deregulation miRNAa expression has been described a variety tumors papillary thyroid carcinoma (PTC). The aim the present study was to investigate role selected miRNAs PTC and find associations between miRNA BRAF (V600E) mutation.The group comprised total 62 patients with...
