Clinical and laboratorial profile and histological features on minor salivary glands from patients under investigation for Sjogren´s syndrome
2013
Diagnosis of Sjögren's syndrome (SS) is complex and the usefulness of labial minor salivary glands biopsy in this process remains controversial. Objectives: to evaluate the clinical and laboratorial profile and histological features on labial minor salivary glands from patients under investigation of SS. Study D esign: clinical charts from 38 patients under suspicion of SS and submitted to labial minor salivary glands biopsies were reviewed. Clinical and laboratorial data were retrieved from the clinical files and the HE-stained histological slides were reviewed under light microscopy. Results: mean age of the patients was 56.5 years and 97% were females; histological analysis showed that 4…
IL-34 is overexpressed in the inflamed salivary glands of patients with Sjogren's syndrome and is associated with the local expansion of pro-inflamma…
2013
Objectives To investigate the expression of IL-34 in labial salivary glands (LSGs) of patients with primary SS (p-SS) and its role in inducing a pro-inflammatory monocyte phenotype. Methods LSG biopsies were obtained from 20 patients with p-SS and 10 patients with non-Sjogren's sicca syndrome (n-SS). The expression of IL-34, IL-1β, TNF-α, IL-17 and IL-23 was assessed by real-time PCR. IL-34 expression was also investigated in LSGs by immunohistochemistry. The frequencies of subpopulations of CD14(+) monocytes were evaluated by flow cytometry among isolated mononuclear cells from peripheral blood and salivary glands from both patients and controls. The role of recombinant IL-34 on isolated p…
Efficacy and safety of rituximab treatment in early primary Sjögren's syndrome: a prospective, multi-center, follow-up study.
2013
Introduction Primary Sjögren’s syndrome (pSS) is an autoimmune disorder affecting exocrine glands; however, a subgroup of pSS patients experience systemic extra-glandular involvement leading to a worsening of disease prognosis. Current therapeutic options are mainly empiric and often translated by other autoimmune diseases. In the last few years growing evidence suggests that B-cell depletion by rituximab (RTX) is effective also in pSS. Patients with early active disease appear to be those who could benefit the most from RTX. The aim of this study was to investigate the efficacy and safety of RTX in comparison to disease modifying anti-rheumatic drugs (DMARDs) in early active pSS patients. …
Rituximab modulates IL-17 expression in the salivary glands of patients with primary Sjögren's syndrome.
2014
OBJECTIVE: The aim of this study was to evaluate the role of rituximab (RTX) in modulating the expression of the IL-17/IL-23 pathway in the salivary glands (SGs) of patients with primary SS (pSS). METHODS: Consecutive SG biopsies were obtained from 15 patients with pSS before and after 1 year of RTX therapy. The SG expression of IL-17, IL-23p19 and p-STAT3 was evaluated by immunohistochemistry at baseline and after RTX therapy. The role of mast cells in pSS patients in modulating the Th17 response and the immunologic effect of RTX on mast cells were also studied in in vitro experiments. RESULTS: IL-17 was overexpressed in the SGs of patients with pSS mainly by infiltrating T cells and mast …
Interventional treatment of sialoliths in main salivary glands
2002
Purpose. The aim of our study was to demonstrate the effectiveness of interventional radiology in the treatment of sialolithiasis, as the first-choice treatment for the removal of stones located in the middle and proximal tracts of the main salivary ducts, and to assess its limitations and contraindications. Material and methods. Between February 1998 and May 2001 eleven interventional removals of sialoliths were performed for recurrent obstruction of the main salivary duct associated with chronic sialadenitis. Patients were selected on the basis of a preliminary sialogram, designed to determine the location and size of the stone. Exclusion criteria were location of the stone in the gland h…
Epidemiology and treatment of adenoid cystic carcinoma of the minor salivary glands: a meta-analytic study.
2010
OBJECTIVES: To evaluate the epidemiological aspects of adenoid cystic carcinoma (ACC) and to evaluate the different therapeutic possibilities as well as the percentage of survival. STUDY DESIGN: A retrospective, meta-analytic, observational study was carried out by selecting a total of 13 articles, which provided a sample size of 263 cases of patients who had been diagnosed with ACC in the minor salivary glands. RESULTS: ACC was found to be more common among women (56.5%) and the average age at diagnosis was 55.26 years old. The primary location of the tumor was in the palate in 57% of the cases, the predominant pattern being cribiform. The treatment of choice was therapy combined with surg…
Identification of predictive variables for the recurrence of oral mucocele
2018
Background Oral mucocele is the most common minor salivary gland lesion with good prognosis after surgical removal. However, its recurrence is not rare, sometimes bothersome. This study aimed to identify the possible predictive variables affecting the recurrence rate of oral mucocele. Material and Methods The histoclinical data of 164 patients diagnosed with oral mucocele were retrospectively obtained by reviewing dental records. The predictive variables for its recurrence were identified by analyzing its recurrence rate according to clinical variables. Results The recurrence rate showed the significant differences according to location and age. Oral mucocele recurred with significantly hig…
The role of a labial salivary gland biopsy in the diagnostic procedure for Sjögren’s syndrome; a study of 94 cases
2014
Objectives: The purpose of the present study is to examine the role of the outcome of the labial salivary gland biopsy (LSGB) in the diagnostic procedure of patients suspected of suffering from Sjögren's syndrome (SS). Material and Methods: In a retrospective study the result of histopathological assessment of 94 consecutively taken labial salivary gland biopsies has been examined. For the diagnosis of SS the American-European Consensus Group classification (AECG, 2002) have been used. The outcome of the assessment has been discussed in relation to a recently reported classification provided by the American College of Rheumatology (ACR, 2012). Results: In the 94 LSGBs support for a diagnosi…
Safety and efficacy of an intra-oral electrostimulator for the relief of dry mouth in patients with chronic graft versus host disease: case Series
2013
Objectives: Patients with chronic graft-versus-host disease (cGVHD) often suffer from dry mouth and oral mucosal lesions. The primary objective of this study was to investigate the safety of an intra-oral electrostimulator (GenNarino) in symptomatic cGVHD patients. The secondary objective was to study the impact on the salivary gland involvement of cGVHD patients. Study Design: This paper presents a case series. The study included patients treated for 4 weeks, randomly assigned to the active device and then crossed-over to a sham-device or vice versa. The patients and clinicians were blind to the treatment delivered. Data regarding oral mucosal and salivary gland involvement were collected.…
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…
