Sialographic findings in Wharton duct evagination
2009
Ductal evagination is a rare condition affecting the Wharton duct. The aim of this study was to establish the incidence, imaging features and clinical significance of ductal evagination in patients undergoing submandibular gland sialography. The sialographic findings and reports of 322 patients undergoing submandibular gland sialography during the period 1998-2007 were retrospectively reviewed. Ductal evagination was identified on sialograms as a unique diverticulum, filled with contrast medium, of the Wharton duct, with a narrow neck and a blind end. A ductal evagination was found in 5/322 patients with swelling and pain in the submandibular gland. It was always located in the middle tract…
ANF IN THE PAROTID GLAND IN RABBIT.
2012
It is well known that the presence of a particular type of granule population has been discovered in the atrial cardiocytes which represent the major site of synthesis of atrial natriuretic factor. The ANF has potent natriuretic, diuretic and vasoactive functions. However, ANF evidence occurs in extracardiac tissues such as the brain, intestine, lymphoid organs and in various glands involved in water and salt regulation adrenals, pancreas, lacrimal and salivar glands with respect to salivary glands the literature reportes that ANF presence was found in the acinar cells and on the contrary in the ductal cells. In order to eliminatethese discordances researchers conducted a previous study on …
Metastatic Renal Cell Carcinoma to Submandibular Gland: A Rare Occurrence
2015
Approximately 20-30% of patients affected by renal cell carcinoma (RCC) present with metastatic disease, and 20% to 40% undergoing nephrectomy for clinically localized disease will develop metastases. A 53 years old female patient developed a left submandibular swelling. Four years before she experienced a left radical nephrectomy for a clear cell tumor and two years later right kidney was removed for a cancer having the same histologic subtype. In that circumstance duodenal pancreasectomy was required for infiltration of pancreatic gland. A sialoadenectomy has been performed and pathology demonstrated an intraglandular neoplasm with characteristics of a clear renal cell carcinoma. Although…
Human salivary proteome and sensitivity to bitterness
2012
Bitterness is present in every day beverages (e.g. coffee) and foods (e.g. vegetables such as cruciferous plants). However, bitterness is perceived differently among individuals and some foods considered as healthy may be rejected due to their bitter taste. Several genetic (eg. genetic polymorphism of bitter taste receptors) or environmental (eg. age, medications) factors partly explain the interindividual variability in bitterness perception. However, other peri-receptor factors may intervene, in particular salivary composition. First, in order to investigate the link between salivary proteome and sensitivity to bitterness, the detection threshold to the bitter taste of caffeine was measur…
