Occupation and risk of upper aerodigestive tract cancer: The ARCAGE study
2012
We investigated the association between occupational history and upper aerodigestive tract (UADT) cancer risk in the ARCAGE European case-control study. The study included 1,851 patients with incident cancer of the oral cavity, oropharynx, hypopharynx, larynx or esophagus and 1,949 controls. We estimated odds ratios (OR) and 95% confidence intervals (CI) for ever employment in 283 occupations and 172 industries, adjusting for smoking and alcohol. Men (1,457 cases) and women (394 cases) were analyzed separately and we incorporated a semi-Bayes adjustment approach for multiple comparisons. Among men, we found increased risks for occupational categories previously reported to be associated wit…
Two-year clinical performance of a packable posterior composite with and without a flowable composite liner
2003
The aim of the study was to evaluate the clinical performance of a packable fine hybrid dental composite (Prodigy Condensable) and the influence of the additional application of a flowable resin composite (Revolution, SDS Kerr) layer on marginal integrity after 2 years in stress-bearing posterior cavities according to the Ryge criteria. In 50 patients (40.5+/-17.5 years of age), 116 class II fillings (metal matrix system, glass ionomer-cement-base in 36%, rubberdam isolation in 70%) were placed, with at least two restorations per patient. The adhesive Optibond Solo Plus was used for all the restorations. In one of the two fillings in each patient, an additional layer of the flowable composi…
Mucoceles of the oral cavity : a large case series (1994-2008) and a literature review
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). The mean age of the patients was 31.9 years, with a peak of occurrence in…
Anxiety sensitivity as predictor of pain in patients undergoing restorative dental procedures
2006
Abstract – Objectives: The personality disposition to anxiety sensitivity refers to beliefs about negative consequences of bodily arousal. The concept has recently been successfully applied in research on chronic pain conditions. The present study investigated whether anxiety sensitivity interacts with dental fear to increase expected and experienced pain during routine dental treatment. Methods: Subjects were 97 patients undergoing dental procedures of excavation and filling. Anxiety dispositions were measured by the Anxiety Sensitivity Index and the Dental Anxiety Scale. Expected and experienced pain were assessed by affective and sensory verbal descriptor scales and a numerical rating…
Placement of endosseous implants in patients with oral epidermolysis bullosa.
2000
Abstract Objective: To evaluate the feasibility of placing endosseous implants in patients with recessive dystrophic epidermolysis bullosa. This article reports on 4 patients subjected to follow-up. Study Design: Implants were placed in 4 cases. All patients have marked oral involvement, with devastating alterations in the soft and hard tissues in all cases. Results: A total of 15 implants (7 maxillary, 8 mandibular) were placed. All implants integrated successfully and have been restored. The average follow-up from implant placement was 2.5 years (range, 1-4). Conclusions: Our preliminary findings suggest that endosseous implants can be successfully placed and can provide support for prost…
Mechanics of pericardial effusion: A simulation study
2015
Pericardial effusion is a pathological accumulation of fluid within pericardial cavity, which may compress heart chambers with hemodynamic impairment. We sought to determine the mechanics underlying the physiology of the hemodynamic impairment due to pericardial effusion using patient-specific computational modeling. Computational models of left ventricle and right ventricle were based on magnetic resonance images obtained from patients with pericardial effusion and controls. Myocardial material parameters were adjusted, so that volumes of ventricular chambers and pericardial effusion agreed with magnetic resonance imaging data. End-diastolic and end-systolic pressure–volume relationships …
Clinical performance of a new medullary humeral nail: antegrade versus retrograde insertion.
2001
Objective A new intramedullary nail system for humeral shaft fractures is evaluated to determine whether retrograde nailing is as reliable as antegrade nailing. Study design Prospective multicenter nonrandomized clinical study. Patients Eighty-four patients with acute humeral shaft fractures were nailed with the new unreamed humeral nail (UHN) system. Fifty-seven nails were introduced retrogradely, and twenty-seven antegradely. Bone healing and functional outcome were the follow-up parameters. Results The ratio of perioperative complications was equivalent for both groups, but one shaft fracture and three fractures or fissures at the entry point occurred in the group with retrograde nail in…
Efficacy and safety of an intraoral electrostimulation device for xerostomia relief: a multicenter, randomized trial.
2011
Objective To evaluate the efficacy and safety of an intraoral electrostimulation device, consisting of stimulating electrodes, an electronic circuit, and a power source, in treating xerostomia. The device delivers electrostimulation through the oral mucosa to the lingual nerve in order to enhance the salivary reflex. Methods The device was tested on a sample of patients with xerostomia due to Sjogren's syndrome and other sicca conditions in a 2-stage prospective, randomized, multicenter trial. Stage I was a double-blind, crossover stage designed to compare the effects of the electrically active device with the sham device, each used for 1 month, and stage II was a 3-month open-label stage d…
Bolus-enhanced renal spiral CT: technique, diagnostic value and drawbacks
1994
Abstract In addition to pre- and postcontrast renal CT scans, early bolus-enhanced spiral scans during demarcation of the corticomedullary junction were acquired in 85 patients. The diagnostic value and drawbacks of the three imaging series in the evaluation of renal disease were assessed. Renal calcifications and calculus disease detected at precontrast scans (18%) were obscured after contrast administration and excretion in most cases. In the detection of renal lesions bolus-enhanced spiral CT and delayed postcontrast scans had an identical diagnostic yield (94%). Bolus-enhanced spiral CT was superior in the assessment of lesion vascularity and vascular anatomy as well as opacification of…
Are mucous retention cysts and pseudocysts in the maxillary sinus a risk factor for dental implants? A systematic review
2020
Background Mucous retention cysts and pseudocysts of the maxillary sinus are benign lesions present in up to 13% of adult patients. Different surgical approaches for sinus lift and dental implant placement in the presence of these lesions have been proposed. Material and Methods A systematic review was performed following the PRISMA statement recommendations to answer the PICO question: Does the aspiration or removal of mucous retention cysts/pseudocysts before or during sinus lifting and dental implant placing, affect the survival of the implants? The study was pre-registered in PROSPERO (CRD42020185528). Included articles quality was assessed using the “NIH quality assessment tool” and “T…
