Salivary diagnostics

K Möller, N Kohles, D Eßer
Salivary gland surgery is a common procedure in otorhinolaryngology. Parotidectomy and submandibulectomy represent the treatment of choice in benign and malignant tumors of the salivary glands. However, as to this point there are no guidelines are concerning diagnostic and therapeutic approaches of benign and malignant tumors of the salivary gland. Since the introduction of sialendoscopy there are new diagnostic and therapeutic procedures available in treating obstructive sialadenitis. The present article provides an overview of anatomical principles, diagnostic approaches and the most important salivary gland surgeries for future otorhinolaryngologists under specialist training...

OBJECTIVES: Extending prior studies of prenatal adversity and depressive symptoms, we tested associations between maternal prenatal major depressive disorder (MDD) and infant cortisol regulation. Based on prior findings by our group, we also tested placenta glucocorticoid (HSD11B2 methylation) and serotonin (SLC6A4 gene expression) signaling as moderators of links between prenatal MDD and infant cortisol. METHODS: Participants were 153 mother-infant pairs from a low-income, diverse sample (M [SD] age = 26[6] years)...

BACKGROUND: Sialodochitis fibrinosa is a rare disease which is characterized by recurring episodes of pain and swelling of the salivary glands due to the formation of mucofibrinous plugs. Analytic studies ascertain elevated levels of eosinophils and immunoglobulin E (IgE). Imaging studies such as magnetic resonance imaging (MRI) and sialography reveal dilation of the main salivary duct (duct ectasia). Treatment is initially supportive, consisting of compressive massages, and use of antihistamines and/or corticosteroids...

BACKGROUND: Many previous studies have indicated that individuals who are depressed or at risk for depression are characterized by increased levels of morning cortisol and a greater cortisol awakening response (CAR). However, despite the high comorbidity between depressive and anxiety disorders, fewer studies have examined whether these diurnal cortisol abnormalities are also characteristic of anxiety or risk for anxiety. METHODS: In the present study we examined cortisol in a community sample of 476 female adolescents and related it to maternal history of depression and/or anxiety disorders...

Sialoendoscopy has recently emerged as an alternative to gland excision in management of recurrent sialoadenitis and sialolithiasis. This technique has both diagnostic and therapeutic purposes. We report a case of unusual device failure during removal of a submandibular stone from Wharton's duct, which ultimately led to ductal avulsion. Sialoendoscopy is safe and effective in management of non-neoplastic major salivary gland disorders. Ductal avulsion can happen during mechanical procedures like stone removal or dilation of strictures...

Background. Submandibular oncocytomas are rare benign salivary gland neoplasms. They are typically found in Caucasian patients aged 50-70 years with no gender preference. Due to the overlapping histological and clinical features of head and neck tumors, they are often misdiagnosed. Methods. We report a case of unilateral submandibular gland oncocytoma in a 63-year-old Caucasian man. Results. The patient underwent unilateral submandibular gland resection and histopathologic analysis of the tumor specimen. On follow-up at 2 weeks and 1 year, no recurrence was identified...

Metastasis to the oral cavity is a rare occurrence with renal cell carcinoma (RCC) being the third most common tumor to metastasize to this location. Buccal mucosa is rarely involved and in the absence of a known primary, such lesions pose a diagnostic challenge to the pathologist. The histomorphological features may mimic a primary salivary gland neoplasm adding to the dilemma. We present one such case of metastatic RCC of the buccal mucosa.

Myoepithelial cells (MECs) are considered to be a key participant in most salivary gland diseases, particularly tumors. MECs structurally resemble both epithelial cells and smooth muscles. Diagnostic dilemmas caused are due to inadequacy of characterizing the wide spectrum of morphologic and immunologic features which are different for both normal and neoplastic MECs. This article discusses the development, functions and structure of both normal and neoplastic MECs, their staining properties and differences in the morphologic and immunophenotypic properties of the MEC in detail...

Cardiovascular disease (CVD) is a major threat to global health, estimated to be the cause 30 % (17.3 million in 2008) of deaths every year, and the number of deaths caused by CVD is expected to increase further, reaching 23.3 million by 2030. Hence, there is a growing demand for simpler sample extraction, rapid screening results, and intervention of the subsequent analysis in emergency units. In this paper, we reviewed CVD biomarkers in blood- and saliva-based specimens. The history of cardiac biomarkers indicates that in the beginning, cardiac troponin I (cTnI) was a widely accepted 'gold standard' marker due to its high specificity and selectivity...

BACKGROUND: The role of BRAF mutations in cancerogenesis has been demonstrated in several solid tumor types. However, in salivary gland tumors, this genetic alteration is very uncommon, and its role still remains unclear. Thus, the aim of this study was to analyze BRAF V600E (VE1) protein expression with BRAF mutation status in codon 600, in malignant and benign salivary gland tumors. METHODS: Studies were performed on archived formalin-fixed paraffin-embedded tissue sections derived from 95 patients who underwent surgery for tumors of the salivary gland...

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) is a heterogeneous group of tumours with a typical 5 year survival rate of <40 %. DNA methylation in tumour-suppressor genes often occurs at an early stage of tumorigenesis, hence DNA methylation can be used as an early tumour biomarker. Saliva is an ideal diagnostic medium to detect early HNSCC tumour activities due to its proximity to tumour site, non-invasiveness and ease of sampling. We test the hypothesis that the surveillance of DNA methylation in five tumour-suppressor genes (RASSF1α, p16 (INK4a) , TIMP3, PCQAP/MED15) will allow us to diagnose HNSCC patients from a normal healthy control group as well as to discriminate between Human Papillomavirus (HPV)-positive and HPV-negative patients...
