PURPOSE: Most tumors have obvious biologically active fibroblasts known variously as myofibroblasts or cancer-associated fibroblasts (CAFs) in the stroma. CAFs have been known as an important factor of cancer invasion and metastasis. This study aimed to investigate the presence of CAFs in patients with papillary thyroid carcinoma (PTC) and evaluate the correlation between CAFs and cervical lymph node (LN) metastasis in PTC through immunohistochemistry. METHODS: The medical records of 128 patients who were diagnosed with PTC from January 1, 2010 to December 31, 2010 were reviewed, and 78 patients who underwent total thyroidectomy with or without neck dissection, were included in this study...

BACKGROUND: Narrow band imaging (NBI) in combination with white light endoscopy (WLE) has improved the accuracy for the diagnosis and follow-up of head and neck carcinomas by identifying changes in the vascular patterns of the mucosa. However, NBI evaluation is explorer-dependent and may be influenced by the learning curve. The aim of this study is to assess the intra and interobserver agreement of NBI and WLE at the office, under local anaesthesia, by either experienced or non-experienced observers...

Marcel Sauvalle, Andrés Alvo
BACKGROUND: The respiratory epithelium is mainly constituted by caliciform (produces mucus, responsible of keeping moisture and trapping particles) and ciliated cells (transports mucus into the pharynx, by the movement of multiple cilia). For centuries, nasal lavages have been used for different rhinosinusal conditions. Some studies suggest not only a direct effect on the mobilisation of secretions, but also an improvement in mucociliary clearance rates. To our knowledge, the impact of temperature in nasal lavages has been scarcely studied...

Tary Yin, Marie Jardine, Anna Miles, Jacqui Allen
PURPOSE: Structural and functional pharyngeal changes occur with age. How these affect swallowing in healthy older adults is not well defined. This study presents quantitative pharyngeal anatomic features in healthy adults using videofluoroscopic study of swallowing (VFSS). This will help our understanding of the normal changes in swallowing that occur with age and illustrate what may constitute normal variation compared with abnormal swallow function. METHODS: 138 mixed gender adults with no history of dysphagia were recruited and underwent a standardized VFSS protocol...

Nasal Polyposis (NP) is a complex multi-factorial disease; associated with several environmental, genetic and inflammatory factors. TNF-alpha is one of the major pro-inflammatory cytokines involved in NP pathogenesis. Some of the polymorphisms of this gene affect its expression. Therefore, the aim of this study was to evaluate the polymorphism of TNF-alpha G/A308 gene and its association with nasal polyposis in north part of Iran. In this case-control study, 60 patients with NP and 75 healthy individuals referred to Guilan University hospital were evaluated...

PURPOSE: Septic cavernous sinus thrombosis (CST) is a rare complication of infections in the head and neck area. CST is notorious for its bad prognosis, with high mortality and morbidity rates described in literature. However, these rates are based on old series. We question whether the prognosis of CST is currently still as devastating. The primary purpose of this study is to assess the mortality and morbidity of CST. METHODS: Using the databases of all relevant specialties in our tertiary referral hospital, we collected all the patients treated for CST in the period 2005-2017...

BACKGROUND: Spontaneous CSF leak is a challenging condition, with frequent recurrences following attempted surgical closure. The selection of graft materials depends on the experience of the operating surgeon. Leukocyte- and platelet-rich fibrin (L-PRF) is a second-generation platelet concentrate that has currently invaded every surgical specialty. To our knowledge, no previous reports about the use of L-PRF in repair of CSF leak were published. The study was conducted to assess the potential role of L-PRF in spontaneous CSF leaks repair...

PURPOSE: Quality assurance is much more difficult to achieve in surgical oncology than in medical oncology and radiotherapy where doses are standardized and toxicities are well-classified. To better define what is required in surgery, we analyzed recent articles addressing the point in head and neck surgery. RESULTS: The surgical report should match with the pathological description of the resected specimen with accurate delineation of the margins, number and level(s) of lymph nodes (capsular rupture if any)...

PURPOSE: A novel precision three-dimensional (3D)-printed paranasal sinus-skull base anatomical model was generated with a commercial grade desktop 3D printer. A specific page-turning pattern was employed in this model, to display the internal spatial structure of the paranasal sinus. METHODS: The CT image data of paranasal sinus were imported into the Mimics software to construct a 3D digital paranasal sinus-skull base model. Then, the model was sliced in the coronal position and loaded into the 3D printer to print each slice of the paranasal sinus-skull base model at a ratio of 1:1 in size...

PURPOSE: To investigate the feasibility of lymph drainage mapping (LDM) using SPECT/CT to help select head and neck cancer (HNSCC) patients for unilateral elective neck irradiation (ENI). Patients with lateralized HNSCC treated with radiotherapy routinely undergo bilateral ENI, despite the incidence of contralateral regional failure being relatively low even after unilateral ENI. We hypothesized that patients with a lateralized tumor without visible lymph drainage to the contralateral neck have an extremely low risk of contralateral involved nodes...
