Cloud-Based Multicenter Data Collection and Epidemiologic Analysis of Bisphosphonate-Related Osteonecrosis of the Jaws in a Central European Population

Objective: Bisphosphonate-related osteonecrosis of the jaws is considered to be a rare but severe complication of bisphosphonate therapy. To understand this condition better, data collection is essential. Although the number of scientific papers about this subject is large, to date only a few multicenter reports have been published. Study design: We present a novel cloud-based data collection system for the evaluation of the risk factors of bisphosphonate-related osteonecrosis of the jaws. Web-based questionnaire and database have been set up and made available to voluntary researchers and clinicians in oral and maxillofacial surgery in Hungary and Slovakia. Results: To date, fifteen colleagues from eight maxillofacial units have joined the study. Data of 180 patients have been recorded. Collected data were statistically analysed and evaluated from an epidemiological point of view. Conclusions: Authors consider cloud-based multicenter data collection a useful tool that allows for real-time collaboration between users, facilitates fast data entry and analysis, and thus considerably contributes to widening our knowledge of bisphosphonate-related osteonecrosis of the jaws

A 2-es típusú diabetes mellitus prevalenciájának változása szájüregi carcinomás betegek körében

INTRODUCTION: Data proves that Hungary has a leading role in the statistics of oral cancer and patients living with type 2 diabetes. AIM: Our aim was to understand the statistical correlation between oral cancer and metabolic disorder (diabetes mellitus and impaired fasting glucose) due to the valuable data from the Semmelweis University. METHOD: We analyzed the data of 835 patients diagnosed with malignant oral cancer and 587 tumor-free control patients. We investigated the incidence and location of oral cancer among patients living with diabetes, and compared these datasets with our previous data from 14 years earlier. RESULTS: We found that in oral cancer patients, 26.1% had diabetes and 20.8% had impaired fasting glucose; in the control group these ratios were 10.8% and 11.1%. This difference is significant (p<0.05). 14 years ago in the tumor group 14.6%, in the control group 5.6% had diabetes, while 9.7% and 5.5% had impaired fasting glucose. Lip cancer had the biggest incidence. CONCLUSIONS: The rise of type 2 diabetes in the tumor group was significant. This could be a burden for the health care system. We want to highlight the importance of interdisciplinary cooperation between health care professionals. Orv Hetil. 2018; 159(20): 803-807

The Effect of Platelet-Rich Fibrin Membrane in Surgical Therapy of Medication-Related Osteonecrosis of the Jaw

We examined the effect of the membranous form of platelet-rich fibrin (PRF) on patients with medication-related osteonecrosis of the jaw.Our study included patients who underwent an operation because of second- or third-stage osteonecrosis of the jaw induced by antiresorptive therapy. The diagnosis of medication-related osteonecrosis of the jaw was based on the 2009 and 2014 recommendations of the American Association of Oral and Maxillofacial Surgeons. On the basis of the duration of treatment, we divided our patients into 2 groups. Patients in the first group (Gr1) underwent traditional surgical therapy between 2009 and 2014, whereas patients in the second group (Gr2) underwent PRF membrane-supplemented operations between 2015 and 2017. Outcomes were assessed based on patient recovery, stage improvement, and relapse rate. The follow-up period was a minimum of 1 year.Our study included 101 patients: 73 in Gr1 and 28 in Gr2. The results in Gr2 were significantly better than those in Gr1: recovery (P = .022), stage improvement (P = .005), and relapse rate (P < .001).In Gr2, significantly better results were achieved in terms of stage improvement, recovery, and relapse rate than in Gr1

A gyógyszer okozta állcsontnekrózis és a vércukorszint kapcsolata : Retrospektív epidemiológiai vizsgálat

Bevezetés: A diabetes mellitus és a különböző szájüregi elváltozások szoros kapcsolatát számos irodalmi adat bizonyítja. Munkacsoportunk az elsők között tárta fel az oralis malignus daganatok és a cukorbetegség epidemioló- giai összefüggéseit. A nemzetközi szakirodalomban már megjelentek olyan publikációk, amelyek a cukorháztartás és a gyógyszer okozta állcsontnekrózis közötti kapcsolatot vizsgálták. Célkitűzés: Jelen tanulmányunkban arra a kérdésre kerestük a választ, hogy a hazai populációban a biszfoszfonát okozta állcsontnekrózisban szenvedő betegek körében milyen gyakorisággal fordul elő diagnosztizált cukorbetegség és emelkedett éhomi vércukor. Megvizsgáltuk továbbá, hogy van-e összefüggés a rendellenes cukorháztartás és a betegek alapbetegsége, valamint az állcsontnekrózis lokalizációja, súlyossága között. Módszer: Az adatgyűjtés során a 2018. június 1. és 2020. december 31. közötti időszak betegdokumentációját tanul- mányoztuk. A vizsgálatba 349 főt vontunk be, akik ezen időszak alatt a Semmelweis Egyetem Arc-Állcsont-Szájsebé- szeti és Fogászati Klinikájának Fekvőbeteg Osztályán kerültek ellátásra. A betegeket két csoportra osztottuk: biszfoszfonát okozta állcsontnekrózisban szenvedőkre, valamint kontrollcsoportra. Eredmények: A két vizsgált csoportot összehasonlítva megállapítottuk, hogy a biszfoszfonát okozta állcsontnekrózisban szenvedő betegcsoportban szignifikánsan több a diabetes mellitusban szenvedő és az emelkedett éhomi vércukorral rendelkező beteg. Megbeszélés: Kutatásunk eredményei alapján felmerül, hogy a diabeteses vagy hyperglykaemiás betegek esetében a dysglykaemia microvascularis szövődményei miatt a biszfoszfonát okozta állcsontnekrózis előfordulási valószínűsége szignifikánsan gyakoribb. Következtetés: Az emelkedett vércukorszint szignifikánsan növeli az állcsontnekrózis valószínűségét invazív fogorvosi, illetve szájsebészeti beavatkozások után
