The aim of the study was to evaluate the effectiveness of organ spare sialolitiasis treatment by sialoscopy-guided techniques. The study included 317 patients with parotid and submandibular sialolitiasis. In 22 patients conventional surgical approach was used because of distal location and larger size of concrements, while in 295 miniinvasive sialoscopy-guided procedures were performed. The use of sialoscopy-guided approach drastically diminished the rate of submandibular glands extirpations (performed in 5% of patients), as well as early and long-term surgical complications...

Lipomas are the most commonly encountered benign mesenchymal tumors, but their occurrence in the head and neck is rare, even more at the level of the parotid region where they can be found nearby the parotid capsule, inside the capsule, or within the gland. In addition, lipomas involving the deep parotid lobe are extremely unusual. That is why lipomas are not often considered for differential diagnosis of parotid lumps. Concerning diagnostic tools, magnetic resonance imaging (MRI) is nowadays considered as the main imaging examination for parotid lipomas due to a characteristic signal intensity on T1- and T2-weighted images...

Even with advanced inverse-planning techniques, radiation treatment plan optimization remains a very time-consuming task with great output variability, which prompted the development of more automated approaches. One commercially available technique mimics the actions of experienced human operators to progressively guide the traditional optimization process with automatically created regions of interest and associated dose-volume objectives. We report on the initial evaluation of this algorithm on 10 challenging cases of locoreginally advanced head and neck cancer...

(no author information available yet)
Salivary duct carcinoma is a rare tumor, commonly involving parotid gland. It typically affects middle aged to elderly males. The tumor has an aggressive behaviour and is notorious for early metastasis, high rate of local recurrence, and high mortality. Treatment is mainly surgical but other modalities are also used. We are reporting 2 cases in females who had different presentation, course of disease, treatment, and prognosis.

Sjögren's syndrome (SS) is a chronic and progressive multisystem autoimmune disease typically managed by rheumatologists. Diagnostic delays are common, due in large part to the non-specific and variable nature of SS symptoms and the slow progression of disease. The hallmark characteristics of SS are dry eye and dry mouth, but there are a broad range of other possible symptoms such as joint and muscle pain, skin rashes, chronic dry cough, vaginal dryness, extremity numbness or tingling, and disabling fatigue...

Esophageal squamous cell carcinoma (ESCC) is often diagnosed at late incurable stage and lacks effective treatment strategy. Bufadienolides are cardiotonic steroids isolated from the skin and parotid venom glands of the toad Bufo bufo gargarizans Cantor with novel anticancer activity. However, there is little information about the effects and action mechanisms of bufadienolides on ESCC cells. In this study, the in vitro and in vivo anti-ESCC activities of bufadienolides, including bufalin (Bu) and arenobufagin (ArBu), were examined and the underlying molecular mechanisms were elucidated...

Chronic obstructive parotitis (COP) is a common disease of the parotid gland. A total of 104 patients with COP were identified and randomized into a treatment group (52 cases) and a control group (52 cases). All patients underwent sialography and salivary gland scintigraphy (SGS) examinations before surgery. The patients in the treatment group received chymotrypsin combined with gentamicin via interventional sialendoscopy to irrigate the duct, and the control group received gentamicin alone. All patients were asked to record their pain on a visual analogue scale (VAS) before treatment and at 1 week, 2 weeks, 1 month, 3 months, and 6 months after surgery...

BACKGROUND: Dry eye is a common problem in Ophthalmology and may occur for many reasons including Sjogren's syndrome (SS). Recent studies have identified autoantibodies, anti-salivary gland protein 1 (SP1), anti-carbonic anhydrase 6 (CA6) and anti-parotid secretory protein (PSP), which occur early in the course of SS. The current studies were designed to evaluate how many patients with idiopathic dry eye and no evidence of systemic diseases from a dry eye practice have these autoantibodies...

BACKGROUND: Histatins are histidine rich polypeptides produced in the parotid and submandibular gland and secreted into the saliva. Histatin-3 and -5 are the most important polycationic histatins. They possess antimicrobial activity against fungi such as Candida albicans. Histatin-5 has a higher antifungal activity than histatin-3 while histatin-3 is mostly involved in wound healing in the oral cavity. We found that these histatins, like other polycationic peptides and proteins, such as LL-37, lysozyme and histones, interact with extracellular actin...
