Efficacy of mometasone furoate microemulsion in the treatment of erosive-ulcerative oral lichen planus: pilot study
2004
Background: Oral lichen planus (OLP) is a frequent immunological chronic disease, having different clinical forms: asymptomatic and symptomatic. Symptomatic OLP has been palliated with topical corticosteroids with different levels of efficacy and safety. The purpose of this pilot phase II clinical trial was to determine the efficacy of mometasone furoate microemulsion upon the symptoms and signs of erosive-ulcerative OLP. Methods: Forty-nine patients with clinical and histologically confirmed erosive-ulcerative OLP were enrolled in this study (36 women and 13 men). Their average age was 56.4 years (from 28 to 78). The treatment consisted of 0.1% mometasone furoate microemulsion mouthwash …
Investigation of the prevalence of impacted third molars and the effects of eruption level and angulation on caries development by panoramic radiogra…
2021
This study is aimed to determine the prevalence of impacted third molars and to investigate the effects of their eruption level and angulation on caries formation in the distal of the adjacent tooth. This cross-sectional study was conducted on panoramic radiographs of 38481 patients who were admitted to the Trakya University, Faculty of Dentistry. The panoramic radiographs of 7998 patients with at least one impacted third molar were included. Third molars were classified according to Winter?s classification and Pell and Gregory?s classification. The frequency of caries in partially impacted third molars and adjacent second molars was determined. The chi-square tests were used to determine p…
Relationship between rheological properties, in vitro release and in vivo equivalency of topical formulations of diclofenac.
2019
Determination of bioequivalence remains a challenge in generic topical drug development. To support pharmacokinetic studies, strategies to demonstrate microstructure sameness of the products being compared include in vitro evaluations, such as the comparison of rheological properties, droplet size and in vitro release rates. Nevertheless, defining the appropriate acceptance range to consider equivalence between test and reference formulation is complex. To shed more light into this issue, in vitro release and rheological properties were compared to in vivo bioequivalence data (systemic blood measurements within a clinical trial) after topical application of a single dose. Test and reference…
A randomized trial assessing the effectiveness of different concentrations of isotretinoin in the management of lichen planus
2004
The aim of our 10-year study was to test the effectiveness of topical therapy based on 0. 18% isotretinoin, comparing it with that most frequently used, i.e. at 0.05% concentration. Seventy patients with an established diagnosis of oral lichen planus were involved in the study. The patients were randomly divided into two groups, and the drug was administered topically at 0.05% and 0. 18% concentrations. The drug at the higher concentration, according to the same protocol, was administered to the patients who did not benefit from the therapy at the lower concentration. None of the cases of reticular lichen planus showed clinical or histological improvement. In contrast, the atrophic-erosive …
The effects of an amine fluoride/stannous fluoride and an antimicrobial host protein mouthrinse on supragingival plaque regrowth.
2004
BACKGROUND: Chlorhexidine (CHX)-containing mouthrinses are recommended as adjuncts to mechanical oral hygiene. The problem associated with side effects, however, has stimulated the search for alternative antiplaque agents. The aim of this study was to investigate the plaque inhibitory effects of two mouthrinses containing amine fluoride/stannous fluoride (ASF) and antimicrobial host proteins (lactoperoxidase, lysozyme and lactoferrin; LLL), respectively. METHODS: The study was an observer-masked, randomized 4x4 Latin square cross-over design balanced for carryover effects, involving 12 healthy volunteers in a 4-day plaque regrowth model. A 0.12% CHX mouthrinse and a saline solution served a…
[Effectiveness of contemporary injection of botulinum toxin and topical application of glyceryl trinitrate against postoperative pain after Milligan-…
2007
PURPOSE: After haemorrhoidectomy the maximum resting pressure (MRP) of the anal canal is significantly increased. This increase play an important role in the making of postoperative pain. Recently, both the topical application of glyceryl trinitrate (GT) and the intrasphincter injection of botulinum toxin (Tox), resulted effective, in reducing temporary the MRP although with different mechanism of action. In this study the effectiveness and safe of contemporary injection of Tox and topical application of 300 mg/die of GT after Milligan-Morgan haemorrhoidectomy, were evaluated. MATERIALS AND METHODS: Ten patients, undergoing Milligan-Morgan haemorrhoidectomy for 3rd and 4th degree haemorrhoi…
Topical prazosin attenuates sensitivity to tactile stimuli in patients with complex regional pain syndrome
2015
Background The sympathetic nervous system may play an important role in certain forms of chronic pain. The main aim of this study was to determine whether functional blockade of α1-adrenoceptors would alter sensitivity to cutaneous stimulation in patients with complex regional pain syndrome (CRPS). Methods and Results In an initial study, high-performance liquid chromatography-mass spectrometry of intradermal interstitial fluid collected from the forearms of three healthy individuals established that the α1-adrenoceptor antagonist prazosin penetrated the skin barrier when mixed in Lipoderm® cream base. Next, we found that application of this cream to the forearm of 10 healthy participants a…
Application of a capsaicin rinse in the treatment of burning mouth syndrome
2010
Objective: To examine the efficacy of a new topical capsaicin presentation as an oral rinse in improving the symptoms of burning mouth syndrome (BMS). Study design: A prospective, double-blind, cross-over study was made of 30 patients with BMS. There were 7 dropouts; the final study series thus comprised 23 individuals. The patients were randomized to two groups: (A) capsaicin rinse (0.02%) or (B) placebo rinse, administered during one week. After a one-week washout period, the patients were then assigned to the opposite group. Burning discomfort was scored using a visual analog scale (VAS): in the morning before starting the treatment, in the afternoon on the first day of treatment, and at…
Use of topical tranexamic acid in primary total hip arthroplasty. Efficiency and safety. Our experience.
2019
Abstract Background and aim Intravenous tranexamic acid has been shown to reduce bleeding and the need for transfusions in total hip arthroplasty, although it has a theoretical risk of producing thromboembolic phenomena. Recently some papers have been published using the topical application of tranexamic acid, but the ideal administration protocol has not yet been clearly defined. The aim of this paper was to demonstrate that our protocol of topical tranexamic acid is effective and safe. Methods Prospective data collection from a case series of 80 primary hip arthroplasties, in which the following topical tranexamic acid protocol is used: 1.5 g diluted to a total volume of 60 ml were admini…
"Dry biopsies" with spraying of dilute epinephrine optimize biopsy mapping of long segment Barrett's esophagus
2008
BACKGROUND AND STUDY AIMS: For surveillance of Barrett’s esophagus random stepwise four-quadrant biopsy (4QB) is recommended for detecting macroscopically occult neoplasias. Thorough performance of the systematic protocol is commonly hampered by poor visibility due to oozing from biopsy sites. Topical application of dilute epinephrine may prevent bleeding by vasoconstriction of superficial microvessels and might therefore enable ”dry biopsy” sampling. The aim of this study was to examine the safety and efficacy of spraying dilute epinephrine for optimal 4QB mapping of Barrett’s esophagus. PATIENTS AND METHODS: In this prospective, double-blind trial 40 patients with known long segment Barre…
