Comparison of two different labial salivary gland biopsy incision techniques: A randomized clinical trial
2013
Objectives: To compare the reliability of two different labial salivary gland biopsy (LSGB) incision techniques (vertical versus horizontal incision techniques) and to report the related complications and discomfort. Study Design: 163 patients who underwent LSGB were included in this study. Patients were randomly divided as vertical incision group (n=81) and horizontal incision group (n=82). Demographic and clinical information of each patient were recorded. A questionnaire was prepared and applied together with Visual Analog Scale (VAS) on the subjects verbally at the 7th day, postoperatively. Intraoperative, short- term and delayed complications were evaluated. Results: The mean age of pa…
Exhaled nitric oxide is associated with cyclic changes in sexual hormones
2013
Abstract Background We hypothesized that changes in the levels of sexual hormones during the menstrual cycle influence the concentration of nitric oxide in the exhaled air (FeNO) and alveolar exhaled nitric oxide (CANO). Methods Twelve healthy, non allergic women in their reproductive age (age range 25–37 years) were recruited. Subjects were studied, on alternate days, over the course of their menstrual cycle. At each visit, measurements of FeNO and CANO were performed. Progesterone and 17-β-estradiol concentrations were measured in salivary samples. Results Eight subjects completed the study. The levels of FeNO and CANO were 13 ± 4.7 pbb and 3.5 ± 1.9 pbb, respectively (mean ± SD). The mea…
Unilateral submandibular gland aplasia with ipsilateral sublingual gland hypertrophy presenting as a neck mass
2010
The congenital absence off the major salivary glands is a very infrequent disorder, in which several glands are usually involved at the same time. Sometimes this disorder can be associated with other developmental anomalies. The unilateral aplasia of the submandibular gland is an extremely rare finding with only 14 cases reported in the literature. Clinically, this kind of patients may complain of dryness of the mouth, difficulties in chewing and swallowing, severe periodontal disease or multiple caries, but usually they follow an asymptomatic course. Salivary gland aplasia can be diagnosed with a large variety off imaging techniques, which include computer tomography (CT), magnetic resonan…
Salivary gland choristoma in the buccinator muscle: A case report and literature review
2015
Salivary gland choristoma (SGCh) is defined as the presence of normal salivary tissue in an abnormal location. It is a rare entity in oral and maxillofacial region and its ethiology is unknown. The typical presentation of salivary gland heterotopia is an asymptomatic mass that may or may not produce saliva. Some examples of ectopic salivary tissue in the pituitary gland, in the lymph nodes, in the middle ear, in the neck, in the jaw, in the thyroid gland, in the mediastinum and in the rectum have been documented in literature. We report the case of a 61-year-old male presented with a bilateral tumorlike mass in the cheek. The mass was painless, of fibrous consistency and had size change wit…
Salivary gland application of botulinum toxin for the treatment of sialorrhea
2007
Sialorrhea or excessive salivation, and drooling, are common and disabling manifestations in different neurological disorders. A review is made of the literature, based on a PubMed search, selecting those articles describing clinical trials involving the injection of botulinum toxin A in the salivary glands of patients with different diseases characterized by sialorrhea. The most frequently treated diseases were infant cerebral palsy (30%), Parkinson’s disease (20%) and amyotrophic lateral sclerosis (15%). Over half of the authors injected the product into the parotid glands, 9.5% into the submaxillary glands, and 38% into both. The total doses of toxin injected varied from 10-100 units of …
Lactobacillus aquaticus sp. nov., isolated from a Korean freshwater pond.
2009
A Lactobacillus strain, IMCC1736T, was isolated recently from a Korean freshwater pond following an extensive study of the microbial community in this ecosystem. Its 16S rRNA gene was sequenced and phylogenetic analysis placed this strain within the Lactobacillus salivarius group, closely related to Lactobacillus satsumensis NRIC 0604T, with 97.9% sequence similarity. In the present work, the taxonomic status of strain IMCC1736T has been re-evaluated. It was characterized phylogenetically, genotypically and phenotypically and, based on DNA-DNA hybridization values, this strain represents a novel Lactobacillus species. Strain IMCC1736T can be differentiated genotypically from its closest rel…
Epithelial-myoepithelial carcinoma of the minor salivary glands: a case report

Mucocele de la glandula submaxilar: a propósito de un caso
2005
El mucocele es un término que incluye dos conceptos: el quiste de extravasación, que resulta de la ruptura del conducto de la glándula salival y el consiguiente derrame de la mucina en los tejidos blandos que rodean a dicha glándula, y el quiste de retención, que tiene su origen en la disminución o ausencia de la secreción glandular como consecuencia de la obstrucción del conducto de la glándula salival. No se puede considerar al mucocele como un verdadero quiste, ya que su pared carece de revestimiento epitelial. Este tipo de patología es muy común en las glándulas salivales menores ( sobretodo en las labiales), pero es muy poco frecuente en las glándulas salivales mayores y en concreto, e…
Marsupialización modificada de ránula gigante intraoral: reporte de caso
2016
ResumenLa ránula intraoral es una enfermedad benigna seudoquística de extravasación que tiene su origen en las glándulas salivales sublinguales. Es una entidad poco prevalente. Es más frecuente en niños y adolescentes, con características clínicas propias que la diferencian de otras entidades de la boca.Su tratamiento es quirúrgico y varias técnicas han sido descritas en la literatura: marsupialización simple y modificada, enucleación de la lesión, extirpación de la glándula junto con enucleación de la ránula.Si bien la extirpación de la glándula junto con la enucleación de la lesión es el tratamiento definitivo radical y más aceptado, la marsupialización modificada puede ser útil como alte…
Lymphoid lesions of salivary glands : malignant and Benign
2007
Lesions of salivary glands with a prominent lymphoid component are a heterogeneous group of diseases that include benign reactive lesions and malignant neoplasms. Occasionally, these pathologic entities present difficulties in the clinical and pathological diagnosis and prognosis. Lymphoepithelial sialadenitis, HIV-associated salivary gland disease, chronic sclerosing sialadenitis, Warthin tumor, and extranodal marginal zone B-cell lymphoma are examples of this pathology that are sometimes problematic to differentiate from one another. In this paper the author reviewed the main clinical, pathological and prognostic features of these lesions.
