Melatonin enhances vertical bone augmentation in rat calvaria secluded spaces.
2015
Background Melatonin has many roles, including bone remodeling and osseointegration of dental implants. The topical application of melatonin facilitated bone regeneration in bone defects. We evaluated the effects of topical application of melatonin on vertical bone augmentation in rat calvaria secluded spaces. Material and Methods In total, 12 male Fischer rats were used and two plastic caps were fixed in the calvarium. One plastic cap was filled with melatonin powder and the other was left empty. Results Newly generated bone at bone defects and within the plastic caps was evaluated using micro-CT and histological sections. New bone regeneration within the plastic cap was increased signific…
Chemo-radiotherapy induced oral mucositis during IMRT for head and neck cancer: an assessment
2014
Background This study is conducted mainly to evaluate the changes in quality and quantity of oral epithelial cells during the course of IMRT. Material and Methods 30 Patients undergoing chemo-radiotherapy were followed through course of treatment. They were compared with a group of age- and sex-matched healthy individuals. The procedure involved WHO clinical scoring, collection of oral washings and preparation of buccal smears from both study group and control group. The changes occurred were recorded as a way of assessing the severity of oral mucositis. Results Revealed a significant occurrence of oral mucositis in almost all patients during weekly follow up. There was a significant increa…
Bisphosphonate-related osteonecrosis of the jaws (Bronj).
2011
Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is an extremely therapy resistant osteomyelitis-like disease exclusively involving the jaw bones of patients in treatment with bisphosphonates (BPs). Objectives: The aim of this study was to evaluate the radiological and clinical findings and management of 51 patients with BRONJ diagnosed from 2004 to 2009 in our Reference Center. Study Design: A prospective study was performed. The patients were examined every 2-6 months, depending on their clinical conditions. Outcome variables were the resolution of symptoms, persistence of bone exposure and / or fistula and the status of the lesional mucosa. Results: The higher prevalence of the d…
Global Geriatric Assessment and In-Hospital Bleeding Risk in Elderly Patients with Acute Coronary Syndromes: Insights from the LONGEVO-SCA Registry.
2018
Background: Bleeding risk scores have shown a limited predictive ability in elderly patients with acute coronary syndromes (ACS). No study explored the role of a comprehensive geriatric assessment to predict in-hospital bleeding in this clinical setting. Methods: The prospective multicentre LONGEVO-SCA registry included 532 unselected patients with non-ST segment elevation ACS (NSTEACS) aged 80 years or older. Comorbidity (Charlson index), frailty (FRAIL scale), disability (Barthel index and Lawton-Brody index), cognitive status (Pfeiffer test) and nutritional risk (mini nutritional assessment-short form test) were assessed during hospitalization. CRUSADE score was prospectively calculated …
Oral lichen planus: a retrospective study of 633 patients from Bucharest, Romania
2012
Objective: In this retrospective study, patients’ medical records were reviewed to investigate the profiles of 633 OLP cases in a group of Romania. Material and Methods: In this retrospective study, the following clinical data were obtained from the medical charts of patients: gender, age, clinical presentation of OLP, site affected, presence of symptoms, extraoral manifestations of lichen planus, presence of systemic diseases, and history of medications. Results: Most (78.67%) OLP patients were female and the mean age at presentation was 52 years. The white type of the disease (reticular/papular/plaque lesions) was the main form encountered in this sample (48.97%). Among patients with avai…
Endoluminal sclerosis with diode laser in the treatment of orofacial venous malformations
2012
Introduction: The appearance of vascular anomalies in the orofacial area is a common condition, which represents about 50% of these malformations. Traditional treatment approach, such as surgery and chemical sclerosis has been given way to a few less-invasive options, as the use of the 810nm diode laser to induce the sclerosis of the venous malformation by intralesional photocoagulation. Objectives: The objective of this study was to determine the efficacy of the diode laser in the intralesional treatment of the orofacial venous malformations (OFVM), describing the recommended surgical approach, as well as to report the main associated complications. Patients and Methods: 10 cases of OFVM, …
Diagnostic criteria in proliferative verrucous leukoplakia: evaluation
2014
Objectives: to evaluate the ability of the diagnostic criteria proposed by Cerero et al in 2010 to perform an early diagnose in patients with proliferative verrucous leukoplakia. Study Design: retrospective study with patients diagnosed with leukoplakia at Oral Medicine Service at Oral Medicine and Surgery Department at Dentistry Faculty at Universidad Complutense of Madrid. Results: the criteria were applied in 116 patients, turning positive in 40 cases. Out of these, 24 (60%) had been previously diagnosed with PVL. Most frequent criteria were major criteria A and E, concerning lesion’s site and histopathology, and minor criteria b and c, concerning sex and smoking habit. Conclusions: diag…
Versatility of nasolabial flaps in oral cavity reconstructions
2014
Objectives: Describe the techniques involved and the results obtained witn nasolabial flaps in small and medium- sized defects of the oral cavity. The procedure is an easy resconstructive option with a high success rate and with very good aesthetic and functional outcomes. Study Design: A retrospective analysis of 16 nasolabial flap reconstructions in 15 oncological patients with oral cavity defects undergoing single-stage surgical interventions. We evaluate the tumor type, its location, size, the resective and reconstructive techniques involved, as well as any complications. Results: Out of 15 patients, 9 were male and 6 female, with ages ranging from 60-85 years. The primary tumor was loc…
Conventional radiofrequency treatment in five patients with trigeminal neuralgia
2010
Introduction: In trigeminal neuralgia, when drug treatment proves ineffective, other management options must be considered. In this context, conventional radiofrequency of Gasser’s ganglion is a safe and effective alternative. Material and Methods: We describe 5 patients with long-evolving trigeminal neuralgia subjected to conventional radiofrequency according to the Sweet technique, with a follow-up of two years. Results: Pain relief was complete after two months in all cases. One patient suffered an unexpected episode of nausea, vomiting and foul odor sensation that subsided after three days of rest and drug treatment. Three patients described non-painful hypoesthesia in the region of the…
Topical treatment of oral lichen planus with anthocyanins
2014
Background: Oxidative stress is involved in oral lichen planus (OLP) pathogenesis; meanwhile anthocyanins are natural antioxidants present in grapes skin. Objectives: The aim of this research was to verify the utility of anthocyanins, extracted from grapes skin, for the local treatment of oral lichen planus and to compare it with clobetasol propionate- neomycin -nystatin cream (CP-NN). Study Design: Prospective, non-randomized study, with control group. Fifty-two patients with OLP were includ - ed. We divided patients into two categories: erosive oral lichen planus (EOLP) and non erosive oral lichen planus (NEOLP). 38 had EOLP (17 cases and 21 controls) and 14 presented NEOLP types (9 cases…
