2009
Objectives: Evaluating data of patients affected by oral mucoceles, examined at the Unit of Oral Medicine and Pathology of the University of Milan between January 1994 and December 2008. Study Design: Concise review on oral mucoceles and analysis of the clinical files of patients who underwent excisional biopsy (patient age, medical history, diagnosis, date and site of the biopsy, histopathological diagnosis and recurrences if any). Results: During the period June 1994-December 2008, 158 mucoceles were observed (93 males and 65 females), with the most frequent site being the lower lip (53%) (p=0.001 by Fisher?s test).

Arachnoid cysts: does surgery improve epileptic seizures and headaches?
1995
During the period from 1985 to 1992 we treated 43 patients with intracranial arachnoid cysts (ACs). In this retrospective study we assessed the outcome of these patients with regard to non-specific symptoms such as headaches and epileptic seizures. Twelve patients had headaches of obscure origin and a mostly temporal located AC. Six of these 12 underwent surgery. After the operation 4 patients (4/6) had no further headaches, two remained unchanged. The other 6 conservatively treated patients (6/12) had further headaches. Ten of the 43 patients had epileptic seizures. One patient dropped out of the survey. Six of the 9 remaining patients had a temporal AC. Four of these 6 underwent surgery; …
Odontogenic tumours in Nigeria : a multicentre study of 582 cases and review of the literature
2018
Background The objective of this study was to classify the various types of odontogenic tumours (OTs) using the newly updated 2017 world health organization (WHO) histological typing and to analyze the prevalence of these tumours among Nigerians as well as to compare the results obtained with reports from world-wide studies. Material and Methods The records of four major tertiary hospitals in Nigeria were reviewed over a 12-year (2004-2015) period. Lesions diagnosed as odontogenic tumours were classified into four groups according to the 2017 WHO histological typing. Data which consisted of age, sex and site were analyzed using SPSS for Window (version 20.0; SPSS Inc., Chicago, IL) and freq…
A retrospective clinicopathological study on oral lichen planus and malignant transformation: Analysis of 518 cases
2011
Objective: To investigate the epidemiological and clinical characteristics of a relatively large cohort of patients with oral lichen planus (OLP) from eastern China. Study design: A total of 518 patients with histologically confirmed OLP in a long-term follow-up period (6 months-21.5 years) were retrospectively reviewed in our clinic. Results: Of the 518 patients, 353 females and 165 males were identified. The average age at diagnosis was 46.3 years (range 9-81 years) with the buccal mucosa being the most common site (87.8%). At initial presentation, white lichen and red lichen was seen in 52.3% and 47.7% patients, respectively. Of these, 5 (0.96%) patients previously diagnosed clinically a…
The clinical characteristics of benign oral mucosal tumors
2013
Objectives: To investigate the clinical characteristics and pre-biopsy provisional diagnoses of benign oral mucosal tumors. Material and Methods: A 10- year retrospective analysis of all benign tumors of the oral mucosa, from a univer- Methods: A 10- year retrospective analysis of all benign tumors of the oral mucosa, from a univer - sity- affiliated oral and maxillofacial surgery department. Results: 146 benign tumors were included. The mean age was 49.6 years, with an approximately equal gender dis - tribution. The most prevalent tumor types were lipomatous tumors (27.4%), vascular (23.3%), and salivary gland tumors (16.5%). Tongue, labial and buccal mucosa were the most frequently involv…
Evaluation of bleeding risk and measurement methods in dental patients
2010
Objective: The present study explores bleeding manifestations in routine dental surgical procedures, evaluates the influence of antithrombotic drugs upon bleeding risk, and validates the efficiency of a clinical method for the measurement of bleeding. Material and method: A prospective observational study was made involving a cohort of 99 patients in the setting of normal clinical practice, with the added conduction of prior hematological tests including baseline hemostasis and platelet function, based on a new method (Multiplate System®). For evaluation of the bleeding manifestations, a clinical method was selected that evaluates bleeding on the basis of its duration and the hemostatic mea…
Prevalence of Burnout Among Pain Medicine Physicians and Its Potential Effect upon Clinical Outcomes in Patients with Oncologic Pain or Chronic Pain …
2018
Objective To evaluate the prevalence of burnout among physicians treating patients with chronic pain and to assess the potential relationships between the presence of burnout and patients' clinical outcomes such as pain relief, satisfaction with pain control, and quality of life. Design An observational, prospective, and noncomparative study. Setting Pain medicine clinics. Subjects Physicians from medical departments involved in the management of chronic pain. Patients aged ≥18 years who exhibited moderate chronic pain lasting at least three months. Methods Physicians were evaluated with the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). Patients were evaluated with the Charlson…
Physical activity in adolescence and smoking in young adulthood: a prospective twin cohort study.
2007
Aims To control for familial confounds, we studied the association between adolescent physical activity and later smoking in twin siblings discordant for their baseline physical activity. Design and measurements In this prospective population-based twin study, we asked whether persistent physical activity/inactivity in adolescence (assessed at 16, 17 and 18.5 years) predicted questionnaire-reported daily smoking at ages 22–27. Twins who, on the three baseline questionnaires, consistently reported frequent leisure physical activity (more than three times weekly) were classified as persistent exercisers, those who exercised less than three times monthly were called persistently inactive, ot…
The relevance of uniform reporting in oral leukoplakia: Definition, certainty factor and staging based on experience with 275 patients
2012
The aim of the present study was to evaluate the definition of oral leukoplakia, proposed by the WHO in 2005 and taking into account a previously reported classification and staging system, including the use of a Certainty factor of four levels with which the diagnosis of leukoplakia can be established. In the period 1997-2012 a hospital-based population of 275 consecutive patients with a provisional diagnosis of oral leukoplakia has been examined. In only 176 patients of these 275 patients a firm diagnosis of leukoplakia has been established based on strict clinicopathological criteria. The 176 patients have subsequently been staged using a classification and staging system based on size a…
Incidence of traumatic dental injury in Valencia, Spain
2020
Background While traumatic dental injuries (TDI) are an increasingly frequent occurrence in everyday dental practice, little research on TDIs has been published in Spain. The aim of this study was to determine the incidence of TDIs in a population in Valencia (Spain) and investigate influential variables. In addition, a protocol for TDI data collection is proposed. Material and Methods This retrospective study compiled data from patients attending a private dental clinic between January 2003 and December 2014. The data were collected using a specially-elaborated protocol entitled “Emergency care of acute dental trauma”. Patients responded to each item, and data was added from case radiograp…
