Radioligand therapy (RLT) with Lu-177-labeled PSMA-ligands is a new therapy option for prostate cancer. Biodistribution in normal tissues is of interest for therapy planning. We evaluated if the biodistribution of Ga-68-PSMA-11 is influenced by tumor load. RESULTS: In patients with high tumor load, SUVmean was reduced to 61.5% in the lacrimal glands, to 56.6% in the parotid glands, to 63.7% in the submandibular glands, to 61.3% in the sublingual glands and to 55.4% in the kidneys (p < 0...

BACKGROUND AND PURPOSE: Surgical excision of an affected sublingual gland for treatment of a ranula can carry a potential of a nerve damage or postoperative complications. However, there have been little studies about effective minimally invasive therapeutic method, yet. Our aim was to evaluate the efficacy and safety of ethanol ablation of ranulas and the clinicoradiologic factors that can predict outcome. MATERIALS AND METHODS: This retrospective study evaluated 23 patients with ranulas treated by percutaneous ethanol ablation...

Epithelioid hemangioendothelioma (EHE) is a rare indolent vascular tumor which occurs at liver, lung, bone, and so on. However, the etiology of EHE is evasive.These patients were enrolled at the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2015. Retrospective analysis is done by demographic data of clinical manifestations, laboratory parameters, CT imaging, histological, and immunohistochemical features in 9 cases in Shaanxi.Of the patients, 8 were females (88.9%) and 1 were males (11...

Ranulas pose a challenging situation, both clinically and surgically, because of their location on the floor of the mouth, an area that exhibits tightly-netted vital structures. Several treatments have been proposed, including excision with or without removal of the sublingual gland, marsupialization with or without cauterization of the roof of the lesion, drainage of the lesion, and micro-marsupialization. It has been suggested that a modified micro-marsupialization technique can establish drainage of saliva and formation of new permanent epithelized tracts along the path of sutures, thereby reducing the recurrence...

Mesenchymal stem/stromal cells (MSCs) play crucial roles in maintaining tissue homeostasis during physiological turnovers and injuries. Very little is known about the phenotype, distribution and molecular nature of MSCs in freshly isolated human salivary glands (SGs) as most reports have focused on the analysis of cultured MSCs. Our results demonstrate that the cell adhesion molecule CD34 was widely expressed by the MSCs of human major SGs, namely parotid (PAG), sublingual (SLG) and submandibular (SMG) glands...

The superior salivatory nucleus (SSN) contains parasympathetic preganglionic neurons innervating the submandibular and sublingual salivary glands. Cevimeline, a muscarinic acetylcholine receptor (mAChR) agonist, is a sialogogue that possibly stimulates SSN neurons in addition to the salivary glands themselves because it can cross the blood-brain barrier (BBB). In the present study, we examined immunoreactivities for mAChR subtypes in SSN neurons retrogradely labeled with a fluorescent tracer in neonatal rats...

Mucoepidermoid carcinoma (MEC) is the most common malignant neoplasm of the salivary gland. Albeit common, histological variants have rarely been noted in MEC. Here, we report a 49-year-old man with a sublingual gland tumor. Histologically, the tumor was composed of spindle cells arranged in interlacing fascicules or globular nests. A few bland small glands containing mucous cells were also scattered. The spindle tumor cells completely lacked immunoreactivity for cytokeratin, and exhibited immunoreactivity for vimentin, S-100, HMB-45, Melan A, and SOX10...

Saliva is an easily collected biological fluid with potentially important diagnostic value. While gel electrophoresis is generally used for salivary analysis, we employed the capillary isoelectric focusing technique to allow for a rapid, automated mode of electrophoresis. Capillary isoelectric focusing coupled with UV whole column imaging detection (iCIEF) was used to develop a robust protocol to characterize salivary α-amylase collected from various glands. Notably, three sample preparation methods were examined: ultrafiltration, gel-filtration, and starch affinity interaction with salivary amylase...

Evidence supporting any one treatment for plunging ranula is limited. Standard treatment-complete excision of the sublingual gland and ranula-is invasive and morbid given the close operative proximity to the submandibular duct and lingual nerve. OK-432 (Picibanil; Chugai Pharmaceutical Co., Tokyo, Japan) sclerotherapy has been studied as a less invasive treatment but is inaccessible in the United States. This report illustrates the successful management of a plunging ranula using ultrasound-guided percutaneous ethanol injection...

Lactoferrin (LF) is produced by exocrine glands including salivary gland, and has various functions including infection defense. However, the transfer of LF from peripheral organs into the brain remains unclear. To clarify the kinetics of salivary LF (sLF), we investigated the consequences of sialoadenectomy and bovine LF (bLF) sublingual administration in rats. The salivary glands were removed from male Wistar rats, and we measured rat LF levels in the blood and brain at 1 week post-surgery. We also examined the transfer of LF into the organs of the rats after sublingual administration of bLF...

NUT midline carcinoma (NMC) is a rare and aggressive disease encountered in the midline of the head and neck or mediastinum. Due to its sparse incidence and subtle pathologic features, we aim to increase knowledge and awareness for this pathologic entity. We present an exemplary case of a young, healthy male presenting with oral cavity pain and cervical lymphadenopathy. This patient was initially diagnosed with an unspecified, highly aggressive sublingual gland malignancy and underwent locoregional resection with free flap reconstruction however suffered a rapid local recurrence and widely extensive metastasis within just 1 month...

INTRODUCTION: Sclerosing mucoepidermoid carcinoma of the salivary gland is a rare subtype of mucoepidermoid carcinoma. The most common site of sclerosing mucoepidermoid carcinoma of the salivary glands is the parotid gland, followed by the submandibular gland, and the minor salivary glands. OBSERVATION: Here we report the first case of sclerosing mucoepidermoid carcinoma of the sublingual gland. DISCUSSION: Clinicians should consider sclerosing mucoepidermoid carcinoma in the differential diagnosis of salivary gland neoplasm...

We performed endoscopic transoral neurectomy of the submandibular and sublingual glands to treat drooling. We bilaterally operated two adult cases with treatment-resistant drooling. In these patients, conventional treatment had failed. Repeated botilinum toxin type A (BOTOX®, Abdi Ibrahim Pharmaceutical Company, Istanbul, Turkey) injections had been effective but were becoming less so. The patients benefited from surgery in that their saliva scores decreased. No issue emerged over 6 months of follow-up. Endoscopic transoral neurectomy of the submandibular and sublingual glands reduces saliva production and allows management of drooling in treatment-resistant patients...

BACKGROUND: Cimicifuga racemosa is one of the herbs used for the treatment of climacteric syndrome, and it has been cited as an alternative therapy to estrogen. Apart from hectic fevers, dyspareunia and so on, dry mouth also increase significantly after menopause. It has not yet been reported whether C. racemosa has any impact on the sublingual gland, which may relate to dry mouth. In an attempt to determine this, we have compared the effects of estrogen and C. racemosa on the sublingual gland of ovariectomized rats...

Late effects of radiotherapy for head and neck cancer treatment have been increasingly investigated due to its impact on patients' quality of life. The purpose of this study was to evaluate the effect of low-level laser therapy on hyposalivation, low salivary pH, and quality of life in head and neck cancer patients post-radiotherapy. Twenty-nine patients with radiation-induced xerostomia received laser sessions twice a week, during 3 months (24 sessions). For this, a continuous wave Indium-Gallium-Aluminium-Phosphorus diode laser device was used punctually on the major salivary glands (808 nm, 0...

Continuously feeding a liquid diet to growing rodents strongly inhibits parotid gland growth, due to suppressed growth of acinar cells. This study investigated whether a liquid diet had a similar effect on submandibular and sublingual glands of growing rats. Rats were weaned on day 21 after birth and then fed a pellet diet in the control group and a liquid diet in the experimental group for 0, 1, 2, 4, and 8 weeks. Their submandibular and sublingual glands were excised, weighed, and examined histologically, immunohistochemically (using antibodies to 5'-bromo-2-deoxyuridine and cleaved caspase 3), and ultrastructurally...
