Item Daptomycin Versus Teicoplanin in the Treatment of Osteomyelitis: Results of the Goztepe Retrospective Cohort Study(2021) Sipahi, O. R.; Erdem, H. A.; Kahraman, H.; Kursun, E.; Suntur, B. M.; Demirdal, T.; Nemli, S. A.; Dizbay, M.; Ulug, M.; Oztoprak-Cuvalci, N.; Arda, B.; Quliyeva, G.; Tasbakan, M.; Uysal, S.; Sipahi, H.; Aydemir, S.; Ulusoy, S.; 33870888Objectives: Daptomycin is highly effective against Gram-positive multidrug-resistant bacteria. Publications on daptomycin in osteomyelitis treatment are limited. Patients and methods: In this multicenter retrospective cohort study, the aim was to evaluate the outcomes of osteomyelitis cases having received daptomycin or teicoplanin. This multicenter retrospective cohort study gathered data from seven centers located in five cities of Turkey. Study inclusion criteria were as follows: (a) magnetic resonance imaging and/or direct X-ray revealed osteomyelitis or biopsy pathologic examination results concomitant with osteomyelitis. Chi-squareand Student t-tests were used for statistical comparison. Results: A total of 72 patients, 38 cases in the daptomycin group and 34 cases in the teicoplanin group diagnosed with osteomyelitis fulfilling the study inclusion criteria, were included in the study. Clinical success at the end of induction therapy was achieved in 32/38 cases in the daptomycin cohort vs. 30/34 cases in the teicoplanin cohort (p: 0.73). Conclusion: Although this is a limited experience in a small but well-defined cohort, our data suggest that daptomycin may be a safe alternative to glycopeptides in osteomyelitis treatment. A randomized controlled clinical study involving larger cohorts may increase the available evidence.Item Prognostic Value of C-Reactive Protein to Albumin Ratio in Glioblastoma Multiforme Patients Treated with Concurrent Radiotherapy and Temozolomide(2020) Topkan, Erkan; Besen, Ali A.; Mertsoylu, Huseyin; Kucuk, Ahmet; Pehlivan, Berrin; Selek, Ugur; 0000-0002-7862-0192; 0000-0002-1932-9784; 0000-0001-8120-7123; 32566124; AAD-6910-2021; M-9530-2014; AAG-2213-2021Objective. We investigated the prognostic impact of C-reactive protein to albumin ratio (CRP/Alb) on the survival outcomes of newly diagnosed glioblastoma multiforme (GBM) patients treated with radiotherapy (RT) and concurrent plus adjuvant temozolomide (TMZ).Methods. The pretreatment CRP and Alb records of GBM patients who underwent RT and concurrent plus adjuvant TMZ were retrospectively analyzed. The CRP/Alb was calculated by dividing serum CRP level by serum Alb level obtained prior to RT. The availability of significant cutoff value for CRP/Alb that interacts with survival was assessed with the receiver-operating characteristic (ROC) curve analysis. The primary endpoint was the association between the CRP/Alb and the overall survival (OS).Results. A total of 153 patients were analyzed. At a median follow-up of 14.7 months, median and 5-year OS rates were 16.2 months (95% CI: 12.5-19.7) and 9.5%, respectively, for the entire cohort. The ROC curve analysis identified a significant cutoff value at 0.75 point (area under the curve: 74.9%; sensitivity: 70.9%; specificity: 67.7%;P<0.001) for CRP/Alb that interacts with OS and grouped the patients into two: CRP/Alb <0.75 (n = 61) and >= 0.75 (n = 92), respectively. Survival comparisons revealed that the CRP/Alb <0.75 was associated with a significantly superior median (22.5 versus 15.7 months;P<0.001) and 5-year (20% versus 0%) rates than the CRP/Alb >= 0.75, which retained its independent significance in multivariate analysis (P<0.001).Conclusion. Present results suggested the pretreatment CRP/Alb as a significant and independent inflammation-based index which can be utilized for further prognostic lamination of GBM patients.Item Effects of various analgesics on the level of prostaglandin E2 during orthodontic tooth movement(2014) Tuncer, Zeynep; Polat-Ozsoy, Omur; Demirbilek, Muge; Bostanoglu, EbruAIM: The aim of this double-blind, randomized, placebo-controlled clinical study was to evaluate the analgesic effects of preoperative/postoperative ibuprofen and acetaminophen use after bonding and to find a relation between the pain level and the amount of prostaglandin released. MATERIALS AND METHODS: Forty-eight patients were included and randomly divided to three equal groups that received either ibuprofen, acetaminophen or placebo for pain relief. The pain levels were measured before bonding, after bonding, at first, second, third, and seventh days on a 100 mm visual analogue scale (VAS) and gingival crevicular fluid (GCF) samples were collected at the same time intervals to measure the amount of prostaglandin E2 (PGE2) released. PGE2 levels were determined with ELISA test. The results were evaluated with Wilcoxon and Kruskal-Wallis tests with Bonferroni correction. RESULTS: Acetaminophen and placebo groups showed similar pain levels during the first 2 days, whereas ibuprofen group showed lower pain levels during the first day after bonding. PGE2 levels did not show statistically significant difference in time within the analgesic groups. No significant relation between the pain perceived and PGE2 released was found. LIMITATIONS: The biggest limitation of this study is the subjective nature of pain and its method of evaluation. CONCLUSIONS: The perception of pain by patients taking ibuprofen and acetaminophen at pre/post appliance placement was not different from patients taking placebo. No time-related differences in PGE2 level were found between the groups and no significant correlation was found between the perception of pain and PGE2 levels.Item A clinical dilemma about a new oral anticoagulant treatment(2014) Altin, Cihan; Ozturkeri, Ovgu Anil; Gezmis, Esin; Muderrisoglu, Haldun; 25341482Item Combined catheter thrombus fragmentation and percutaneous thrombectomy in a patient with massive pulmonary emboli and acute cerebral infarct(2015) Ugurlu, Aylin Ozsancak; Cinar, Ozlem; Caymaz, Ismail; Cevik, Halime; Gumus, Burcak; 25550253Item Treatment of Peri-implant Bone Defects with Platelet-Rich Fibrin(2015) Hamzacebi, Burak; Oduncuoglu, Bahar; Aladdinoglu, Emine Elif; 25909530The objective of this study was to investigate and compare the clinical effectiveness of the application of platelet-rich fibrin (PRF) and conventional flap surgery for the treatment of pen-implant bone loss. Nineteen patients (8 women, 11 men) with peri-implant bone loss were randomly allocated to two groups, with the PRF group comprising patients who received fibrin scaffold and the control group made up of those who received only the access flap. At 3 and 6 months after surgery, respectively, the PRF group demonstrated higher mean probing depth reductions (2.41 +/- 1.06 and 2.82 +/- 1.03 mm versus 1.65 +/- 1.02 and 2.05 +/- 0.77 mm) and more gains in clinical attachment level (2.89 +/- 1.01 and 3.31 +/- 1.08 mm versus 1.43 +/- 1.08 and 1.84 +/- 0.81 mm) compared with the control group. In addition, the increase in the amount of keratinized mucosa from baseline to 6 months postoperatively was statistically significant for the PRF group (P < .001). Hence, the data from the current study led to the conclusion that PRF application in peri-implant bone loss provided better clinical results than conventional flap surgery.Item Topical Bevacizumab for the Treatment of Ocular Surface Squamous Neoplasia(2015) Asena, Leyla; Altinors, Dilek Dursun; 26114378Purpose: To determine the efficacy and safety of topical bevacizumab treatment in patients with ocular surface squamous neoplasia (OSSN). Methods: Six eyes of 6 patients with primary OSSN confirmed by impression cytology received topical 5mg/mL bevacizumab 4 times daily for a period of 8 weeks. Patients were evaluated in 2-week intervals. Digital photography images were obtained at each visit and changes in the size of the lesions were analyzed by image analysis software. Results: The mean age of the patients was 6613 (+/- SD) years. Four tumors were nasal in origin and 2 tumors were temporal. The mean reduction observed in the lesion area was 43%+/- 24.2% (range, 20%-71%) in the first month and 68%+/- 29.7% (range, 42%-100%) in the second month when compared with the baseline area. Four patients required tumor excision at the end of the treatment period. Surgical treatment was not necessary in 2 patients due to complete disappearance of the tumor, which was confirmed by impression cytology. The visual acuity was stable in all patients and no systemic or visual side effects were observed during the study period. Conclusions: Topical bevacizumab is effective as a neoadjuvant therapy combined with surgical excision for the treatment of OSSN. Topical bevacizumab may be used before surgery to decrease the size of the excision. Excision may be unnecessary in responsive patients.Item Demographics, Management Strategies, and Problems in ST-Elevation Myocardial Infarction from the Standpoint of Emergency Medicine Specialists: A Survey-Based Study from Seven Geographical Regions of Turkey(2016) Kayipmaz, Afsin Emre; Ciftci, Orcun; Kavalci, Cemil; Karacaglar, Emir; Muderrisoglu, Haldun; 0000-0001-8926-9142; 0000-0002-9635-6313; 0000-0002-2538-1642; 27760229; W-5233-2018; AAG-8233-2020; AAC-2597-2020; ABI-6723-2020Background This study aimed to explore the ST segment elevation myocardial infarction (STEMI) management practices of emergency medicine specialists working in various healthcare institutions of seven different geographical regions of Turkey, and to examine the characteristics of STEMI presentation and patient admissions in these regions. Methods We included 225 emergency medicine specialists working in all geographical regions of Turkey. We e-mailed them a 20-item questionnaire comprising questions related to their STEMI management practices and characteristics of STEMI presentation and patient admissions. Results The regions were not significantly different with respect to primary percutaneous coronary intervention (PCI) resources (p = 0.286). Sixty six point two percent (66.2%) of emergency specialists stated that patients presented to emergency within 2 hours of symptom onset. Forty three point six percent (43.6%) of them contacted cardiology department within 10 minutes and 47.1% within 30 minutes. In addition, 68.3% of the participants improved themselves through various educational activities. The Southeastern Anatolian region had the longest time from symptom onset to emergency department admission and the least favorable hospital admission properties, not originating from physicians or 112 emergency healthcare services. Conclusion Seventy point seven percent (70.7%) of the emergency specialists working in all geographical regions of Turkey comply with the latest guidelines and current knowledge about STEMI care; they also try to improve themselves, and receive adequate support from 112 emergency healthcare services and cardiologists. While inter-regional gaps between the number of primary PCI capable centers and quality of STEMI care progressively narrow, there are still issues to address, such as delayed patient presentation after symptoms onset and difficulties in patient admission.Item The role of delineation education programs for improving interobserver variability in target volume delineation in gastric cancer(2017) Onal, Cem; Cengiz, Mustafa; Guler, Ozan C.; Dolek, Yemliha; Ozkok, Serdar; 0000-0002-2742-9021; 0000-0001-6908-3412; 28339289; D-5195-2014; AAC-5654-2020Objective: To assess whether delineation courses for radiation oncologists improve interobserver variability in target volume delineation for post-operative gastric cancer radiotherapy planning. Methods: 29 radiation oncologists delineated target volumes in a gastric cancer patient. An experienced radiation oncologist lectured about delineation based on contouring atlas and delineation recommendations. After the course, the radiation oncologists, blinded to the previous delineation, provided delineation for the same patient. Results: The difference between delineated volumes and reference volumes for pre-and post-course clinical target volume (CTV) were 19.8% (-42.4 to 70.6%) and 12.3% (-12.0 to 27.3%) (p = 0.26), respectively. The planning target volume (PTV) differences pre-and post-course according to the reference volume were 20.5% (-40.7 to 93.7%) and 13.1% (-10.6 to 29.5%) (p = 0.30), respectively. The concordance volumes between the pre-and post-course CTVs and PTVs were 467.1 +/- 89.2 vs 597.7 +/- 54.6cm(3) (p < 0.001) and 738.6 +/- 135.1 vs 893.2 +/- 144.6 cm(3) (p < 0.001), respectively. Minimum and maximum observer variations were seen at the cranial part and splenic hilus and at the caudal part of the CTV. The kappa indices compared with the reference contouring at pre- and post-course delineations were 0.68 and 0.82, respectively. Conclusion: The delineation course improved interobserver variability for gastric cancer. However, impact of target volume changes on toxicity and local control should be evaluated for further studies. Advances in knowledge: This study demonstrated that a delineation course based on current recommendations helped physicians delineate smaller and more homogeneous target volumes. Better target volume delineation allows proper target volume irradiation and preventing unnecessary normal tissue irradiation.
