Oral biopsy in dental practice

2007

The conclusions drawn from the study of an oral biopsy are considered essential for the definitive diagnosis of diseases of the oral mucosa, and for the subsequent planning of appropriate treatment. Although the obtainment of biopsies is widely used in all medical fields, the practice is not so widespread in dental practice - fundamentally because of a lack of awareness of the procedure among dental professionals. In this context, it must be taken into account that the early diagnosis of invasive oral malignancy may be critical for improving the patient prognosis. However, in some cases the results are adversely affected by incorrect manipulation of the biopsy material. The present study pr…

Tumoren der Ceruminaldrüsen

1987

Tumours originating from the ceruminous glands can be classified into five types: adenomas, adenocarcinomas, adenoid-cystic carcinomas, pleomorphic adenomas and mucoepidermoid carcinomas. The diagnosis is based on histological findings and can be quite difficult if the tumour status has to be determined. Classification into one of the five types of tumours may be facilitated at times by studying the clinical pattern. Three case reports are quoted as examples to illustrate that neoplasias originating from the ceruminous glands can assume considerable proportions and must be considered in differential diagnosis when assessing space-occupying growths in the soft tissue of the neck. Whereas pro…

Oral lichenoid disease as a premalignant condition : the controversies and the unknown

2009

We grouped as oral lichenoid disease (OLD) a series of chronic inflammatory processes with autoimmune base that affect the epithelium of the oral mucosa. This disease presents in 2% of the population with a marked predilection for the female gender, especially perimenopausal women. Clinically, it is characterized by the presence of lineal reticular papules and histologically by liquefaction degeneration of the basal layer of the epithelium associated with an inflammatory infiltrate with a "band-like" disposition on the lamina propria, composed primarily of T lymphocyte cells. Its pathogenicity is associated with deregulation of the cellular immune system, where the activated cytotoxic CD8 a…

La diagnosi precoce della sclerosi sistemica progressiva

2002

BACKGROUND: The study considers the oro-facial manifestations occurring in a group of patients suffering from progressive systemic sclerosis, evaluating their predictive role and monitoring the systemic disease. METHODS: 34 patients with systemic sclerosis were examining: 30 women, 4 men, at the Department of Dental Sciences, Palermo University, from July 1998 to March 2001. All patients were positive for the diagnostic criteria of scleroderma.1 For each patient we considered: observation of any changes in soft tissues of the oral cavity; evaluation of possible xerostomia; evaluation of any fungal infections; presence of prosthetic sores in patients wearing dentures; DMFS evaluation; evalua…

A Particular Focus on the Prevalence of α- and β-Thalassemia in Western Sicilian Population from Trapani Province in the COVID-19 Era

2023

Thalassemia is a Mendelian inherited blood disease caused by α- and β-globin gene mutations, known as one of the major health problems of Mediterranean populations. Here, we examined the distribution of α- and β-globin gene defects in the Trapani province population. A total of 2,401 individuals from Trapani province were enrolled from January 2007 to December 2021, and routine methodologies were used for detecting the α- and β-globin genic variants. Appropriate analysis was also performed. Eight mutations in the α globin gene showed the highest frequency in the sample studied; three of these genetic variants represented the 94% of the total α-th…

Factors associated with the timing of diagnosis of venous thromboembolism: results from the MASTER registry

2008

INTRODUCTION: Signs and symptoms of venous thromboembolism (VTE) are non-specific and thus can make diagnosis difficult, even for an experienced clinician. We aimed to evaluate the timing of diagnosis of deep vein thrombosis (DVT) and pulmonary embolism (PE) in Italian hospitals and to identify individual and clinical predictors of timely or delayed diagnosis. MATERIAL AND METHODS: MASTER is a multicenter prospective registry of patients with acute DVT and PE. Information on clinical presentation and diagnostic methods, temporary and permanent risk factors, were captured by an electronic data network at the time of the index event. RESULTS: Data on 2047 patients (1024 males), 1505 with DVT …

INFLUENCIA DE FACTORES FAMILIARES Y PERSONALES EN LA EVOLUCIÓN NEGATIVA DEL TDAH

2016

Abstract.INFLUENCE OF PERSONAL AND FAMILY FACTORS ON THE NEGATIVE COURSE OF ADHDObjective. To study the effect of the cumulative adversity on the course of ADHD symptoms, associated problems and dysfunctionality of ADHD children. Method. 61 families of children with a clinical diagnosis of ADHD combined subtype were evaluated on two different times (Time I: mean age = 8.7; Time II: mean age = 11). We developed a personal risk index (high levels of ADHD symptoms, high number of associated problems, presence of oppositionism, stressful child characteristics and family history of ADHD), a family risk index (presence of mothers’ psychopathology, high parental stress and dysfunctional discipline…
