... OLP is a chronic inflammatory disorder with periods of relapse and remission and with the potential of malignant transformation (MT). 49,50 The prevalence of this disorder in the general population is approximately 1%-2%. One of the important and debatable points about OLP is its malignant potential, especially in its erosive form. ...
... Internationally each year, many children attend hospital emergency departments (EDs) as a result of injuries sustained while using trampolines [13][14][15]. While many of these injuries are self-limiting, such as sprains or strains that will generally recover with standard methods for relieving pain and swelling, head or spinal injuries that result in costly, debilitating and sometimes life-long damage to an individual's neurological functioning are also seen [16,17]. ...
... Over the past few years, immunotherapy in cancer treatment has been steadily increasing, with numerous evidence supporting its valuable efficacy. For instance, Food and Drug Administration (FDA) granted approval for the use of Pembrolizumab, a humanized anti-programmed death receptor 1 (PD-1) antibody for the treatment of some patients with an advanced form of head and neck cancer in 2016 (6) whereas cetuximab, a monoclonal antibody that binds competitively to the EGFR, was approved by the FDA for late-stage (metastatic) and resistant cases of squamous cell carcinoma (SCC) of the head and neck in 2011 (7). Apart from PD-1, other immune checkpoints such as cytotoxic T-lymphocyte protein 4 (CTLA4), T-cell immunoreceptor with Ig and ITIM domains (TIGIT), and lymphocyte activation gene 3 protein (LAG3) are considered new rational therapeutic targets (8,9). ...
