ABSTRACT
Pleomorphic adenoma is the most common tumor of the benign salivary gland neoplasms, the submandibular gland is the second most common site of PA after the parotid gland. Authors present 3 series case of pleomorphic adenoma in submandibular salivary gland in institution which were admitted in institution within a month interval. Fine needle aspiration cytology (FNAC) of all 3 cases proved to be benign lesion arising from submandibular salivary gland. All 3 cases underwent excision in to and the postoperative period was uneventful. DT removed on 3rd POD and discharged in POD 10. Biopsy report proved to be pleomorphic adenoma in all cases. past studies showed pleomorphic adenoma most commonly occurs in the parotid gland and its occurrence in the submandibular salivary gland is uncommon. Also, age occurrence involves 30s-50s and is more common in females. But all this case was male and occurred in older age group. Early intervention with surgical excision in toto after definite confirmation with FNAC is the treatment of choice in preventing its malignant transformation.
ABSTRACT
Salivary gland tumors show complex histopathology and the treatment depends mainly on the stage of cancer. Induced pluripotent stem cells (iPS) have a great role in regenerative medicine as they can generate pluripotent stem cells from any available cell types as fibroblast. Thus, the aim of this work is to investigate the possible therapeutic effect of (iPS) on induced salivary gland cancer through evaluation of the silent information regulators of sirtuin-1 (Sirt-1), Tgf-β genes and their protein expressions in addition to LncRNA MALAT-1 expression. Thirty male albino rats were employed and divided into three groups (ten rats for each group), group 1 (control): Rats were injected with phosphate buffered saline (PBS), group II induced squamous cell carcinoma (SCC): rats were injected with squamous carcinoma cells (SCC), group III (induced SCC/iPS): SCC treated rats treated with 5 × 106 iPS cells. Submandibular specimens were taken and prepared for histological, histochemical and immunohistochemical studies for Bax and TGF-β3 protein. Also, Real time PCR was performed for Sirt-1, Tgf-β, and MALAT-1 LncRNA genes expression. SIRT-1 and TGF-β protein level expression was assessed by western blot technique. Group III (iPS treated group) revealed more or less normal acinar structure with normal rearrangement of acini and normal intralobular ducts with an increase in their number. In the iPS treated group there was increasing in the amount of mucopoly saccharide in the acinar cells and intensity of BAX immunostaining while, TGF-β3 was decreased in its intensity in comparison to that of the cancer treated group. In addition to Sirt-1, Tgf-β, and MALAT-1 LncRNA expressions were increased in cancer group compared to iPS treated and control groups. Induced pluripotent stem cells play a potential therapeutic role in treatment of induced submandibular gland carcinoma.

ABSTRACT
Sialolithiasis is one of the commonest disease of salivary glands. Submandibular salivary gland or its duct is a major site of sialolithiasis and it is always leads to sialadenitis. However large sialolith formation and self-extrusion is a rare condition. A case of submandibular sialolithiasis is reported where patient presents with recurrent submandibular swelling and subsequently end up with a spontaneous extrusion. The mechanisms and management of the salivary gland calculi are also discussed.

Diabetes being the most common chronic metabolic disorder has a number of complications that affect various parts of the body. Epidermal growth factor (EGF) is well known for its healing capacity. In this article we review the two way relationship between diabetes and EGF, where the former needs to block the latter’s secretion and reduce its expression on order to produce its notorious complications. On the contrary, the latter is capable of reversing the former’s negative adverse effect on various organs of the body. We also shed some light on different studies in the literature that investigated the role of EGF in the dynamics of diabetes, and gain a deeper insight towards the possible applications of local and systemic treatment with EGF in the management of diabetic complications. We also try to answer some questions: EGF and diabetes; Friends or faux? and will EGF be the future trend in reversing damage caused by diabetes and wound healing.
ABSTRACT
Knowledge of relationship between the facial artery and submandibular salivary gland is essential for the surgeon operating in the submandibular region. This study has been under taken to have the knowledge of this relationship. Submandibular region has been dissected on 20 male cadavers in the Department of Anatomy, Sree Narayana Institute of Medical Sciences, Kerala. The course of the facial artery and its relationship to submandibular salivary gland has been followed carefully. The standard description of ascent of the facial artery along the entire length of posterior border of the submandibular salivary gland was seen in 15 out of the 20 sides studied. In 4 out of 20 sides dissected the facial artery reached only the upper part of the posterior border of the gland. The facial artery arose high on the external carotid artery near the angle of the mandible in one specimen. It reached the gland only at its postero-superior angle, pierced through the gland and emerged on the upper part of the lateral surface of the gland. Our study shows that only 1/5 of instances facial artery courses along the posterior border of the gland. In 4/5 of instances it reaches only the upper part of the posterior border.
ABSTRACT
A case was experienced involving submandibular salivary gland swelling (sialoadenopathy), developing after gastroscopy in a 15-year-old female who was suffering from epigastric pain & diarrhea and a case of parotid salivary gland swelling after gastroscopy in a 25-year-old female who was suffering from dyspepsia and epigastric pain. Both patients were the first two cases among about 5,000 gastroscopic examinations of the stomach conducted by the authors. As soon as the gastroscope was withdrawn, unilateral swelling, which was neither painful nor tender, was found in the left submandibular salivary gland area. This swelling disappeared spontaneously in about few hours later.
