Unilateral absence of submandibular gland secondary to stones. Aplasia versus early atrophy.
2009
Major salivary gland absence is a rare disorder. The cause of congenital absence of the salivary glands has not been determined, but it may be associated with ectodermal defects of the first and second branchial arches. Isolated absence of a unilateral submandibular gland is an unusual entity with less than ten cases reported in the literature. The etiopathogenesis of isolated absence of a major salivary gland without other developmental anomalies is still unclear. The formation of a sialolith within the remaining Wharton?s duct, associated with isolated aplasia (versus atrophy) of a unilateral submandibular gland has been recently reported. We describe in this work two cases of sialolithia…
Clinicopathologic and immunohistochemical characterization of 14 cases of angioleiomyomas in oral cavity
2018
Background Angioleiomyoma (ALM) is a benign neoplasm that originates from vascular smooth muscle. It is extremely rare in oral cavity. The objective of this study was to evaluate the clinicopathological and immunohistochemical characteristics of all oral angioleiomyomas registered in a Center of Diagnosis of Oral Diseases from 1959 to 2017. Material and Methods Slides from 14 cases of ALM stained with hematoxylin and eosin (H&E) were analyzed to confirm the diagnosis. Moreover, an immunohistochemical panel with alpha-smooth muscle actin (alpha-SMA), desmin, AE1/AE3, CD68, S-100, and CD34 antibodies was performed to evaluate semi-quantitatively the positive cells. Results ALM correspond to 0…
Clinical and histological features of gingival lesions: A 17-year retrospective analysis in a northern Italian population
2012
Objectives: Only few studies on gingival lesions considered large enough populations and contemporary literature does not provide a valid report regarding the epidemiology of gingival lesions within the Italian population. The histopathological and clinical appearance of 538 gingival lesions from northern Italians are described and discussed here. Study Design: The case records of patients referred for the diagnosis and management of gingival lesions, from October 1993 to October 2009, were reviewed. Data regarding the histological type of lesion were also obtained from the biopsy register for each case, and blindly re-examined. Results: We reported a greater frequency of benign lesions (re…
Morphological characteristics of microcirculation in oral lichen planus involving the lateral border of the tongue.
2009
Oral lichen planus (OLP) is a chronic mucosal condition commonly encountered in dental practice. Lichen planus is believed to represent an abnormal immune response in which epithelial cells are recognized as foreign, secondary to changes in the antigenicity of the cell surface. It has various oral manifestations. The aim of the study was to evaluate the morphological characteristics of microcirculation of lingual lichen planus (LLP). Twenty patients (10 patients with LLP and 10 healthy patients) were examined by means of videocapillaroscopy. The left margin of the lingual mucosa was examined in each patient. The capillary loop length, loop diameter, and capillary density were analyzed on ev…
P53 and bcl-2 immunoexpression in patients with oral lichen planus a nd oral squamous cell carcinoma
2012
Objective: The aim of this study was to determine by immunohistochemistry the presence and significance of p53 and bcl-2 proteins in oral lichen planus (OLP) and oral squamous cell carcinoma (OSCC). Study Design: We used 21 cases diagnosed as OLP 16 diagnosed as OSCC and four normal gingival biopsies taken from healthy patients were used as controls. Slides were processed for immunohistochemistry using anti-p53 and anti-bcl-2 monoclonal antibodies. Results: We found p53 immunoexpression in 71.4� OLP cases and 6� .7� OSCC cases, with no immunoexpres: We found p53 immunoexpression in 71.4� OLP cases and 6� .7� OSCC cases, with no immunoexpresWe found p53 immunoexpression in 71.4� OLP cases an…
Effects of age on depressive symptomatology and response to antidepressant treatment in patients with major depressive disorder aged 18 to 65 years
2020
Background: There is evidence that symptomatology in patients with major depressive disorder (MDD) changes with age. However, studies comparing depressive symptomatology between different age groups during antidepressant therapy are rare. We compared demographic and clinical characteristics in depressed patients of different age groups at baseline and during treatment. Methods: 889 MDD inpatients were divided into four age groups (18–29, 30–39, 40–49, 50–65 yrs.). Demographic and clinical characteristics including depressive symptomatology (assessed by the Inventory of Depressive Symptoms) were assessed at baseline and weekly during treatment. Results: At baseline, young patients (18–29 yea…
Association Between Exstrophy-epispadias Complex And Congenital Anomalies: A German Multicenter Study
2018
To further investigate associated anomalies in exstrophy-epispadias complex (EEC) patients congenital uro-rectal malformations network (CURE-Net) database was systematically screened. In literature the EEC comprises a spectrum of anomalies, mainly occurring "isolated" without additional congenital defects. Nevertheless, previous epidemiological studies indicated a higher association with renal, anorectal, and lower neurotubular anomalies, which may originate from the same developmental morphogenetic fields.Seventy-three prospectively (born since 2009) and 162 cross-sectional recruited EEC patients (born 1948-2008) were analyzed. Associated anomalies were derived from patient's medical data …
Oral health status of a population with multiple sclerosis.
2010
Objective: To determine the oral treatment needs of a sample of patients diagnosed with multiple sclerosis in the Community of Madrid (Spain). Patients and methods: A cross-sectional epidemiological study was carried out with a sample of 64 patients who were aged 25 to 77 years. They were distributed into homogeneous age groups: 54 years. In order to evaluate the oral health status and treatment requirements, the parameters and guidelines of the WHO were used. Results: The prevalence of caries was 100%, or very close in all three groups. As age increased, the morbidity rate decreased, but the mortality rate increased considerably. On analyzing gingival health, 65% of patients had calculus, …
Oral manifestations in a group of adults with autism spectrum disorder
2011
Objective: A number of studies have evaluated the oral health of patients with autism spectrum disorder (ASD), though most have involved children, and no specific oral manifestations have been described. The present study describes the buccodental disorders and hygiene habits in a group of adults with ASD. Study Design: A prospective case-control study was made of a group of patients with ASD (n=30), with a mean age of 27.7 +/- 5.69 years, and of a healthy age-and gender-matched control group (n=30). An evaluation was made of the medical history, medication, oral hygiene habits and oral diseases, with determination of the CAOD, CAOS and OHI-S oral hygiene scores. Results: Most of the patien…
Tooth size changes with age in a Spanish population: Percentile tables
2010
Objectives: The aims of this work were: firstly, to draw up tables of percentile tooth sizes similar to those of Sanin and Savara for three age groups of a Spanish population; secondly, to describe changes in tooth size between those groups over time, as well as observing any sexual dimorphism and, finally, to compare both the Spanish and Sanin and Savara's American population samples. Material and methods: The sample included 359 patients and was divided into three age groups: adolescents, young adults and adults, of both genders. After dental cast digitalization, mesiodistal tooth-size was measured on each dental cast using a digital method. Dental size tables organized by percentiles for…
