Background/aim: Adenoid cystic carcinoma (ACC) is an aggressive neoplasm even though it has low-grade histological appearance and slow growth. The aim of this study was to identify the immunohistochemical and molecular characteristics of ACC, as well as their correlation with the clinical course of patients.
Patients And Methods: This is a retrospective multicenter analysis.

Purpose: Tumor recurrence and distant metastasis are very common in laryngeal squamous cell carcinoma (LSCC). In this study, we examined the potential prognostic value of microRNA-20b-5p (miR-20b-5p), a component of the tumor-related miR-106a/363 cluster.
Materials And Methods: Total RNA was purified from 105 tissue specimens resected from patients having undergone surgical treatment for primary LSCC.
Purpose: Laryngeal squamous cell carcinoma (LSCC), a common type of head and neck cancer, is associated with high rates of metastasis and recurrence. In this study, we investigated the potential combinatorial prognostic value of NOTCH1, Vimentin (VIM), and Metastasis-associated 1 (MTA1) protein in LSCC, using immunohistochemistry.
Materials And Methods: Tissue specimens from 69 patients with LSCC were immunohistochemically evaluated for the protein expression of NOTCH1, VIM, and MTA1.
Background: Nasal polyposis (NP) and sinonasal inverted papillomas (SIP) are considered benign lesions capable of recurrence or malignant transformation although not with the same prevalence. Since fluctuations of Caveolin-1 and Notch-1 proteins expression have been reported in many pathologies, the current study aimed to investigate their involvement in the epithelial transformation observed in SIPs compared to NP.
Methods: Immunohistochemical expression of Caveolin-1 and Notch-1 proteins was assessed in 104 patients with sinonasal lesions (45 NP, 45 SIP and 14 NP with SIP), semiquantively (percentage times intensity).
Background: Proteus Syndrome (PS) is a rare hamartoneoplastic disorder consisting of a disproportionate and asymmetric overgrowth of body parts, leading to severe body and face disfigurement. Individuals with PS frequently need to undergo a number of surgical procedures including Otolaryngology interventions. Their peculiar anatomy turns even the most straightforward intervention to a challenging one.

In this study, we sought to investigate the expression of type III IFNs and their common receptor IFN-λR1/IL-28Ra in Sjögren's syndrome (SS). Type III IFN expression was examined in minor salivary gland tissues (MSG), peripheral blood mononuclear cells (PBMCs), sera and resting or Toll-like receptor (TLR)-stimulated salivary gland epithelial cells (SGEC) from SS patients and sicca-complaining controls.

Patients And Methods: Between June of 2004 and September 2010, 47 retrospectively selected patients (29 males, 18 females) diagnosed with organ confined T1 or T2 glottic cancer, were treated with external 3DCRT in an accelerated hypofractionation schedule. The median age was 70 years.
Dysadherin is a recently discovered cancer-related cell membrane glycoprotein that has an important role in tumor progression and metastasis. We are focusing on the role of dysadherin in E-cadherin downregulation, the different expression patterns of the molecule in cancer of the head and neck and its potential role as a molecular target for future applications in diagnosis, prognosis, and management of the disease.

The aim of this study was to evaluate the expression of VEGF-C/VEGF-D/flt-4 in salivary gland tumors. Thirty-one salivary gland tumors (19 with and 12 without myoepithelial differentiation) were examined.

Our aim was to correlate their protein levels with telomerase catalytic subunit (h-TERT) expression. Using tissue microarray technology, fifty-five paraffin embedded histologically confirmed primary LSSCs and also ten dysplastic lesions were cored at a diameter of 1.

This prospective study investigates whether this protocol has an adverse effect on the medial olivocochlear bundle (MOCB) and/or outer hair cells' (OHCs) function. The distortion product otoacoustic emissions (DPOAEs) and their suppression by means of contralateral application of white noise were used for assessing the function of OHCs and the MOCB, respectively.

Objective: Vincristine is a well known neurotoxic chemotherapeutic agent. Dose dependent and cumulative peripheral neuropathy is the main dose limiting side effect of chemotherapy with vincristine. The mechanisms responsible for the neurotoxic effects of vincristine have not yet been fully understood.

Methods: Case report of a 69-year-old, otherwise healthy, retired carpenter who was referred for treatment of bilateral senile cataract.
Results: A relative afferent pupillary defect and sectorial disc atrophy on ophthalmic examination led to further investigation and identification of an extensive ethmoidal neoplasm with orbital invasion.
