Introduction: Natural killer (NK) cells, of which CD56 is a specific marker, play an important role in host defense against tumors. Cancer stem cells, of which aldehyde dehydrogenase isoform 1 (ALDH1) is an immunohistochemical marker, are a group of tumorigenic cells which are involved in migration and tumor recurrences. We aimed to evaluate the expression of ALDH1 and CD56 in common salivary g...
Chronic sclerosing sialadenitis(also known as Kuttner tumor) is a chronic inflammatory condition of the salivary glands and one of the salivary gland enlargment that was first described by Kuttner in 1896. Unilateral or bilateral involment of the submandibular gland occurs more commonly than any other salivary glands. Few cases of chronic sclerosing sialadenitis in minor salivary glands have be...
introduction: radioisotope scanning is the best method for objective assessment of salivary gland function. thus, it was used in a randomized trial of concomitant pilocarpine for assessment of radiation-induced xerostomia, in addition to subjective evaluation by an approved questionnaire and objective standard xerostomia grading. methods: patients randomized in placebo-controlled trial of piloc...
BACKGROUND Salivary gland dysfunction with xerostomia is a major clinical problem without a causal therapy in most cases. The development of an animal model for scintigraphic assessment of salivary gland function has great clinical relevance for the investigation of promising new diagnostic and therapeutic strategies for chronic salivary gland diseases. This study reports the first experiences ...
Oncocytoma is a rare benign tumor of salivary gland. The name of the tumor is selected due to presence of large granular oncocytes with acidophilic cells.These tumors occur most commonly in the sixth decade of life and sex incidence is equal in men and women.The incidence of this tumor is 78% in parotid gland and 9% in submandibular gland. Oncocytoma are usually solid round tumors that could oc...
hyalinizying clear cell carcinoma is a rare tumor which affects women more than men and is more common in minor salivary glands. the purpose of this paper was to describe a case of hyalinizing clear cell carcinoma of buccal vestibule in a 55-year-old woman. it is important to differentiate this neoplasm from other tumors with clear cell features because of their differences in treatment and cli...
OBJECTIVE Uptake of 99mTc-pertechnetate in salivary glands reflects intact salivary gland parenchyma. However, no standardized protocol for an accurate quantification of parenchymal function has been established so far. METHODS In this paper we report on a validated acquisition protocol supplying a normal database for standardized quantitative salivary gland scintigraphy. RESULTS The major ...
The aim of this study was to evaluate the effects of the first radioactive iodine (I) therapy on functions of salivary glands in patients with differentiated thyroid carcinoma (DTC).There were 36 consented patients with DTC enrolled in this study, who received 3.7 GBq (100mCi) I for ablation after total thyroidectomy. Salivary gland function was assessed using salivary gland scintigraphy in two...
BACKGROUND The purpose of this study was to assess the late side effects of radioiodine therapy (RIT) on salivary gland function. One hundred eighty two patients were evaluated. METHODS Assessment of salivary gland function was performed with salivary gland scintigraphy (SGS), sialometry, and subjective open questions to determine common side effects of RIT on salivary gland function. RESUL...
