BACKGROUND: There is no consensus opinion on a definitive surgical management option for ranulas to curtail recurrence, largely from the existing gap in knowledge on the pathophysiologic basis. AIM: To highlight the current scientific basis of ranula development that informed the preferred surgical approach. DESIGN: Retrospective cohort study. SETTING: Public Tertiary Academic Health Institution. METHOD: A 7-year 7-month study of ranulas surgically managed at our tertiary health institution was undertaken-June 1, 2008-December 31, 2015-from case files retrieved utilising the ICD-10 version 10 standard codes...

Few cases of plunging ranulas (PRs) occur during childhood and the lesions are frequently misdiagnosed. Here, a PR in a child is reported along with a literature review. A seven-year-old female complaining of swelling in the midline neck, left-submandibular region, was evaluated. No oral cavity or major salivary glands abnormalities were detected. On palpation, a soft, painless, and fluid-containing mass was observed. The suspicion PR was performed by ultrasound. The diagnosis was confirmed with a histopathological examination...

The present work describes a rare case of a spontaneous high-grade carcinoma in a seven-week-old Sprague-Dawley female rat that had been included in the control group of an assay of mammary carcinogenesis. The mass was detected at 50days of age, it grown quickly and the animal was humanely sacrificed eight days later. The tumor was located in the left cervical region, in the vicinity of the left submandibular and sublingual glands. It was soft and reddish and had several dens with a bloody content. The tumor was PAS negative and exhibited immunostaining for ER-α...

Fourier transform infrared spectroscopy (FTIR) imaging has been applied to investigate biochemical differences between salivary glands from control and hypertensive rats. Male Sprague-Dawley rats were divided into two groups including a control group and another hypertension group that were treated orally, with N-nitro-l-arginine methyl ester (l-NAME) via drinking water for 3 weeks to develop hypertension. In the control group, rats were treated with only drinking water for 3 weeks. The formalin-fixed paraffin embedded tissue specimens from submandibular and sublingual glands were analysed with a FTIR focal plane array imaging spectrometer and multi-composite images of all tissue sections were analysed simultaneously using Unsupervised Hierarchical Cluster Analysis (UHCA) and the extracted spectra were further analysed using Partial Least Squares Discriminant Analysis (PLS-DA)...

Myoepithelial cells (MECs) exist on the basal surface of acini in major exocrine glands, include myofilaments and various constructive proteins, and share characteristics with smooth muscle and epithelial cells. MECs project several ramified processes to invest acini, and possibly contract to compress acini to support the secretion by the glandular cells. However, the functional roles of MECs in salivary secretion are still unclear. We investigated morphological changes in immunostained MECs using the anti-α-smooth muscle actin (αSMA) antibody in operated or non-operated contralateral (NC) submandibular glands after partial or total resection...

Malignancies are one of the three major causes of renal recipient´s death with a functioning graft after cardiovascular diseases and infections. Among the variety of risk factors, including conventional and specific to transplant recipients, the duration of immunosuppressive therapy, the intensity of therapy, and the type of immunosuppressive agent all have an impact on development of post-transplant malignancy. The aim of our retrospective study was to document the incidence, the type of malignancies, the patient/graft survival in the group of kidney transplant recipients in Slovak Republic, and to identify the factors which influenced the outcome...

Sialolithiasis is a common disease of the major salivary glands. In contrast, Sialolithiasis of Minor Salivary Glands (SMSG) is very rare. Only 2% of all cases of sialolithiasis develop in minor salivary glands and sublingual glands. Furthermore, the clinical and imaging features of SMSG frequently differ from those encountered in major salivary glands thus, hindering proper clinical diagnosis of SMSG. Histologically, SMSG is characterized by ductal ectasia (sometimes with deep cystic dilatation), acinar atrophy and periductal inflammation...

Sjogren's syndrome (SS) is a chronic autoimmune disorder characterized by lymphocytes infiltration in the exocrine glands. Central nervous system complications of primary SS are not rare, but ischemic stroke has been rarely reported. Here we report a 43-year-old female with a two-year history of primary SS, presenting with sudden cerebral infarction. Her primary SS was diagnosed on the basis of clinical features, high levels of serum anti-SSA and anti-SSB antibodies, salivary gland secretion evaluation and positive sublingual gland biopsy results...

BACKGROUND: Marketing new radiography devices necessitates documenting their absorbed X-ray doses. Since the current literature lacks studies on new devices, we assessed the doses of two new devices that had not previously been assessed. OBJECTIVES: The new devices were compared to the Promax three dimensional (3D) scanner at two fields of view (FOV) in nine critical head and neck tissues and organs. MATERIALS AND METHODS: Seventeen thermoluminescence dosimeters positioned in an average-sized male RANDO phantom were used to determine the dosimetry of the three cone beam computerized tomography devices (NewTom VGi, NewTom 5G, and Promax 3D) at two field of views (FOVs), one small and one large...

OBJECTIVES: Idiopathic Burning mouth syndrome (iBMS) is a poorly understood affection characterized by persistent pain in the oral cavity without any clinical or biological abnormality. Opiorphin is a natural inhibitor of enkephalin-inactivating ectopeptidases, mainly produced by salivary glands, that has demonstrated analgesic properties. The objective of the present case-control study was to test the hypothesis of a decrease in opiorphin levels in iBMS patients. MATERIALS AND METHODS: Twenty-one iBMS patients and 21 matched controls subjects were included between 2011 and 2013...
