Nicotine has been reported to increase the intracellular Ca concentration ([Ca]i) in sublingual acini due to neurotransmitter release from nerve terminals associated with the cell preparation (1). However, it is unclear whether or not the same reaction exists in parotid cells. Therefore, we investigated effect of nicotine on Ca mobilization in digested parotid acini from rats. After removing th...

BACKGROUND although several reports indicate that qualitative and quantitative assessments of parotid salivary function are age-stable in healthy adults, there have been no studies of the influence of age on the variability of repeated parotid flow rates. OBJECTIVE to examine the influence of age on the variability of repeated parotid flow rates in unmedicated, healthy adults. MATERIALS AND...

Human papillomavirus (HPV) infection has been shown to be associated with human tumorigenesis. The aim of the present study was to demonstrate the association between HPV infection and parotid gland tumors. Paraffin-embedded tissue sections from 59 cases of parotid gland tumors and 20 normal oral mucosa were subjected to DNA extraction and flow-through hybridization and gene chip technology to ...

conclusions a complete immunohistochemical study should be considered in cases of malignant salivary gland tumors. to reduce the recurrence rate of these tumors, the optimum therapies are radiotherapy and chemotherapy. introduction salivary gland tumors are rare head and neck lesions. the majority are benign, with only 20% of cases malignant. an epithelial-myoepithelial carcinoma is a rare low-...

by increasing number of vessels. salivary gland tumors are uncommon and their overall incidence is about 3 per 100000 per year. salivary gland hemangioma makes up 1 % of all salivary gland tumors. trismus resulting from parotid hemangioma is so rare. the patient was a 6-month-old boy with a huge lesion in his right parotid who referred to shahid sadoughi hospital of yazd, iran. the lesion appea...

Introduction: Parotid glands contain adipose cells in the alveolar connective tissue and sebaceous glands that release lipid-secretary sebum [1]. The effect of parotid fat on parotid ADC measurement has been unavoidably neglected by the single-shot spin-echo echoplanar diffusion-weighted imaging (EP-DWI), which is essentially equipped by fat-saturation to eliminate chemical shift artifact. Unde...

Fig. 2 Conflict interest statement The authors declare that they have no conflict of interest to the publication of this article. Hemangioma, also known as hemangioendothelioma, is the most common parotid gland tumor in childhood. Girls are affected 3 times more frequently than boys [1]. They are usually not noticed in the newborn period but become prominent in the first months of life [2]. The...

INTRODUCTION Benign tumours of the parotid gland constitute about 80% of parotid tumours. The most common benign tumour of the parotid gland is pleomorphic adenoma. Other conditions, like Kimura's disease, may mimic a tumour when they present as a parotid mass. Various modes of treatment have been advocated for the treatment of benign parotid lesions, ranging from enucleation to near-total paro...

OBJECTIVE Facial nerve preservation and oncological safety are crucial in surgery of parotid tumors. An unexpected histopathologic diagnosis of a malignant parotid tumor, however, may unfavorably require a second, more radical surgery. The aim of this study was to find out whether the assessment of serological tumor markers in parotid saliva might have some diagnostic significance in the preope...
