The effects of pentoxifylline and tocopherol in jaw osteomyelitis.

ABSTRACT: Objectives:Pentoxifylline (PTX) is a methylxanthine derivative that has been implicated in the pathogenesis of peripheral vessel disease and intermittent lameness. The purpose of this study was to investigate the effect of PTX and tocopherol in patients diagnosed with osteoradionecrosis (ORN), bisphosphonate-related osteonecrosis of the jaw (BRONJ), and chronic osteomyelitis using digital panoramic radiographs. Materials and Methods:This study was performed in 25 patients who were prescribed PTX and tocopherol for treatment of ORN, BRONJ, and chronic osteomyelitis between January 2014 and May 2018 in Seoul National University Dental Hospital. Radiographic densities of the dental panorama were compared prior to starting PTX and tocopherol, at 3 months, and at 6 months after prescription. Radiographic densities were measured using Adobe Photoshop CS6 (Adobe System Inc., USA). Blood sample tests showing the degree of inflammation at the initial visit were considered the baseline and compared with results after 3 to 6 months. Statistical analysis was performed using the Mann-Whitney test and repeated measurement ANOVA using IBM SPSS 23.0 (IBM Corp., USA). Results:Eight patients were diagnosed with ORN, nine patients with BRONJ, and the other 8 patients with chronic osteomyelitis. Ten of the 25 patients were men, average age was 66.32±14.39 years, and average duration of medication was 151.8±80.65 days (range, 56-315 days). Statistically significant increases were observed in the changes between 3 and 6 months after prescription (P<0.05). There was no significant difference between ORN, BRONJ, and chronic osteomyelitis. Only erythrocyte sedimentation rate (ESR) was statistically significantly lower than before treatment (P<0.05) among the white blood cell (WBC), ESR, and absolute neutrophil count (ANC). Conclusion:Long-term use of PTX and tocopherol can be an auxiliary method in the treatment of ORN, BRONJ, or chronic osteomyelitis in jaw.

Project description:BackgroundOsteomyelitis is an intraosseous inflammatory disease characterized by progressive inflammatory osteoclasia and ossification. The use of quantitative analysis to assist interpretation of osteomyelitis is increasingly being considered. The objective of this study was to perform early diagnosis of osteomyelitis on digital panoramic radiographs using basic functions provided by picture archiving and communication system (PACS), a program used to show radiographic images.MethodsThis study targeted a total of 95 patients whose symptoms were confirmed as osteomyelitis under clinical, radiologic, pathological diagnosis over 11 years from 2008 to 2017. Five categorized patients were osteoradionecrosis, bisphosphonate-related osteonecrosis of jaw (BRONJ, suppurative and sclerosing type), and bacterial osteomyelitis (suppurative and sclerosing type), and the control group was 117 randomly sampled. The photographic density in a certain area of the digital panoramic radiograph was determined and compared using the "measure area rectangle," one of the basic PACS functions in INFINITT PACS® (INFINITT Healthcare, Seoul, South Korea). A conditional inference tree, one type of decision making tree, was generated with the program R for statistical analysis with SPSS®.ResultsIn the conditional inference tree generated from the obtained data, cases where the difference in average value exceeded 54.49 and the difference in minimum value was less than 54.49 and greater than 12.81 and the difference in minimum value exceeded 39 were considered suspicious of osteomyelitis. From these results, the disease could be correctly classified with a probability of 88.1%. There was no difference in photographic density value of BRONJ and bacterial osteomyelitis; therefore, it was not possible to classify BRONJ and bacterial osteomyelitis by quantitative analysis of panoramic radiographs based on existing research.ConclusionsThis study demonstrates that it is feasible to measure photographic density using a basic function in PACS and apply the data to assist in the diagnosis of osteomyelitis.

Project description:BackgroundAlcoholic hepatitis is a life-threatening disease, with an average mortality of approximately 40%. There is no widely accepted, effective treatment for alcoholic hepatitis. Pentoxifylline is used to treat alcoholic hepatitis, but there has been no systematic review to assess its effects.ObjectivesTo assess the benefits and harms of pentoxifylline in alcoholic hepatitis.Search strategyThe Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, Science Citation Index Expanded, LILACS, clinicaltrials.gov, and full text searches were conducted until August 2009. Manufacturers and authors were contacted.Selection criteriaAll randomised clinical trials of pentoxifylline in participants with alcoholic hepatitis compared to control were selected for inclusion.Data collection and analysisTwo authors extracted data and evaluated the risk of bias. RevMan Analysis was used for statistical analysis of dichotomous data with risk ratio (RR) and of continuous data with mean difference (MD), both with 95% confidence intervals (CI). Trial sequential analysis (TSA) was also used for statistical analysis of dichotomous and continuous data in order to control for random error. Where data were only available from one trial, we used Fisher's exact test or Student's t-test.Main resultsFive trials, with a total of 336 randomised participants, were included. A total of 105 participants (31%) died. Of the five included trials, four (80%) had a high risk of bias. Meta-analysis using all five trials showed that pentoxifylline reduced mortality compared with control (RR 0.64; 95% CI 0.46 to 0.89). However, this result was not supported by trial sequential analysis, which adjusts for multiple testing on accumulating data. Furthermore, four of the five trials were judged to have a high risk of bias, thus risking an overestimated intervention effect. Meta-analysis showed that pentoxifylline reduced the hepatic-related mortality due to hepatorenal syndrome (RR 0.40; 95% CI 0.22 to 0.71), but trial sequential analysis did not support this result. Data from one trial suggests that pentoxifylline may increase the occurrence of serious and non-serious adverse events compared to control.Authors' conclusionsThe current available data may indicate a possible positive intervention effect of pentoxifylline on all-cause mortality and mortality due to hepatorenal syndrome, and conversely, an increase in serious and non-serious adverse events. However, the evidence is not firm; no conclusions can be drawn regarding whether pentoxifylline has a positive, negative, or neutral effect on participants with alcoholic hepatitis.
