Cytotoxicity and genotoxicity of salicylate- and calcium silicate-based root canal sealers on primer human periodontal ligament fibroblasts.

Aust Endod J 2021 Jun 7. Epub 2021 Jun 7.

Department of Endodontics, Faculty of Dentistry, Selcuk University, Konya, Turkey.

The aim of this study was to evaluate the biocompatibility of epoxy-resin-based AHPlus, salicylate-based MTA-Fillapex and calcium silicate-based iRootSP root canal sealers. Cytotoxicity was assessed by XTT test. The extracts from sealers of different setting times were serially diluted. Cell viability was calculated as the percentage of the control group (100%). The optimal concentration of each sealer was used at genotoxicity test, and micronuclei formations were detected. Statistical analyses were done by using Kruskal-Wallis and Dunn post hoc test with Bonferroni correction. AHPlus and MTA-Fillapex showed the lowest percentage of cell viability at higher concentrations (1:1, 1:2, 1:4), especially at first 12 h. iRootSP showed higher viability at all concentrations and times than AHPlus and MTA-Fillapex. At genotoxicity assay, AHPlus increased the number of micronuclei. MTA-Fillapex slightly induced micronucleus formation (not significant) and iRootSP was not increased. In conclusion, calcium silicate-based iRootSP had lowest cytotoxic and genotoxic potential and can be considered as a highly biocompatible material.

Prevalence of onychophagia and its relation to stress and quality of life.

Acta Dermatovenerol Alp Pannonica Adriat 2021 Mar;30(1):15-19

Department of Public Health, Faculty of Medicine, Eskişehir Osmangazi University, Eskişehir, Turkey.

Introduction: Onychophagia is defined as putting one's fingers into the mouth and biting the nails. We sought to evaluate the prevalence of onychophagia in university and high school students and its relation to sociodemographic factors, perceived stress, and quality of life.

Methods: A total of 3,475 students were included in the study. A questionnaire including sociodemographic characteristics, items about onychophagia, the Perceived Stress Scale (PSS), and the European Health Impact Scale were used.

Results: The prevalence of onychophagia among university students was 17.6%, and among high school students it was 29.2%. In university students with onychophagia, the median score on the PSS was higher than the median score of students without onychophagia. In high school students, the median score on the PSS was 28.2 for students without onychophagia and 28.0 for students with onychophagia; the difference was not significant. The median scores on the quality of life scale for both university and high school students with onychophagia were lower than the mean score of students without onychophagia.

Conclusions: Onychophagia is a common problem in the general population with a multidimensional etiology. It has dermatological, dental, and psychiatric consequences and comorbidities, and so a multidisciplinary approach is necessary for the prevention and treatment of onychophagia.

European Standard Series Patch Test Results in Contact Dermatitis Patients in a Tertiary Care Hospital.

Sisli Etfal Hastan Tip Bul 2020 25;54(2):206-210. Epub 2020 Feb 25.

Department of Dermatology, Eskisehir Osmangazi University Faculty of Medicine, Eskisehir, Turkey.

Objectives: Sensitization of allergens varies among societies and also it is influenced by various factors, such as age and gender. It may even change over the years. In this study, we aimed to evaluate the patch test results in patients with contact dermatitis (CD) in our center.

Methods: European standard series patch test results of patients with CD between 2017 and 2018 were evaluated retrospectively.

Results: Of the 135 patients, 65 (48.1%) were males, 70 (51.9%) were females. The mean age of patients was 41.43±14.26 (11-78) years. In 78 (57.8%) patients, a positive reaction against at least one allergen was detected. The most common allergens were nickel sulfate (27.4%), potassium dichromate (14.8%), cobalt chloride (11.9%), textile dye mix (8.1%), fragrance mix i, ii (6.7%) and balsam of Peru (4.4%). The sensitization of nickel sulfate was higher in females and sensitization of cobalt chloride and potassium dichromate in males (p=0.03, 0.05, 0.03, respectively). In the multivariate logistic regression analysis, age was independently related to a positive reaction against at least one allergen.

Conclusion: Nickel sulfate, potassium dichromate, cobalt chloride and textile dye mix were the most common allergens. Legal regulations should be made to decrease exposure to allergens.

Conspecific and heterospecific pheromones stimulate dispersal of entomopathogenic nematodes during quiescence.

Sci Rep 2020 03 31;10(1):5738. Epub 2020 Mar 31.

USDA-ARS, Southeastern Fruit and Tree Nut Research Laboratory, Byron, GA, 31008, USA.

Ascaroside pheromones stimulate dispersal, a key nematode behavior to find a new food source. Ascarosides produced by entomopathogenic nematodes (EPNs) drive infective juvenile (IJ) emergence from consumed cadavers and dispersal in soil. Without ascarosides from host cadavers, Steinernema feltiae (EPN) reduce dispersal substantially. To determine whether other Steinernema spp. exhibit the same behavior, we compared S. feltiae and S. carpocapsae IJs without host cadaver pheromones. Unlike S. feltiae, S. carpocapsae IJs continued to disperse. However, S. carpocapsae IJs exhibited a temperature-dependent quiescent period. The IJ quiescent period increased at ≤20 °C but did not appear at ≥25 °C. Consistent with this, S. carpocapsae IJ quiescence increased from 30 min to 24 h at ≤20 °C over 60 days. The quiescent period was overcome by dispersal pheromone extracts of their own, other Steinernema spp. and Heterorhabditis spp. Furthermore, S. carpocapsae IJ ambush foraging associated behaviors (tail standing, waving, and jumping) were unaffected by the absence or presence of host cadaver pheromones. For S. feltiae, IJ dispersal declined at all temperatures tested. Understanding the interaction between foraging strategies and pheromone signals will help uncover molecular mechanisms of host seeking, pathogenicity and practical applications to improve the EPN's efficacy as biocontrol agents.

Ustekinumab in psoriasis: Five-year real life experience from a single tertiary centre.

Dermatol Ther 2020 03 14;33(2):e13224. Epub 2020 Jan 14.

Department of Dermatology, Eskisehir Osmangazi University Faculty of Medicine, Eskisehir, Turkey.

The efficacy and safety of ustekinumab have been demonstrated in randomized clinical trials; however, there are few real-life data evaluating ustekinumab. This observational, retrospective follow-up study included 33 patients with moderate to severe psoriasis vulgaris. Patients were > 18 years old and received at least 16 weeks of ustekinumab. The efficacy of treatment was evaluated as PASI50, PASI75, and PASI90 response rates at 16, 28, 52, 76, and 100 weeks. Side effects associated with ustekinumab were recorded. Of 33 patients, 24 (72.7%) had received 45 mg ustekinumab and 9 (27.3%) 90 mg ustekinumab. At the 16th week of the treatment, 97% of the patients had PASI50, 57.6% had PASI75, and 33.3% had PASI90 response rates. At 16, 28, 52, 76, and 100 weeks, PASI50, 75, and 90 responses were generally higher in naive to biologics and in the 45 mg group than in nonnaive to biologics and in the 90 mg group but the differences were not statistically significant. In conclusion, ustekinumab is an effective and safe treatment option for patients with moderate to severe psoriasis vulgaris. It seems to be more effective in naive to biologics and patients with normal weight.

Anxiety Sensitivity and Quality of Life in Patients with Acne.

Ann Dermatol 2019 Aug 1;31(4):372-377. Epub 2019 Jul 1.

Department of Dermatology, Eskisehir Osmangazi University Faculty of Medicine, Eskisehir, Turkey.

Background: Anxiety sensitivity (AS) is a continuous fundamental fear and defined as extreme fear of anxiety sensations and symptoms. High AS can cause tendency to anxiety disorders. There are many studies evaluating the anxiety in patients with acne; however, AS has not been investigated.

Objective: We aimed to investigate AS in patients with acne.

Methods: Two hundred and fourteen acne patients and 117 healthy control subjects, aged older than 16 years were enrolled in the study. Severity of acne was evaluated by Global Acne Grading System. The acne patients and healthy controls were asked to complete the anxiety sensitivity index-3 (ASI-3), the Beck anxiety inventory (BAI) and the Turkish version of acne quality of life index.

Results: Anxiety and AS levels in acne patients were significantly higher than healthy controls (<0.001). Quality of life was impaired in acne patients. Quality of life was negatively correlated with anxiety and AS levels in acne patients (=0.014, =0.019, respectively). There was no correlation between quality of life and disease severity (=0.556) and also there was no correlation between psychiatric scale scores (ASI-3, BAI) and disease severity (=0.147, =0.871, respectively).

Conclusion: To our knowledge, our study is the first to report that AS is high in acne patients. Clinically, our results suggest that there might be a relationship between AS and acne. We conclude that further studies are needed in order to clarify the relationship between acne and AS and to investigate the efficacy of cognitive behavioral treatments in acne patients.

The efficacy and safety of omalizumab in refractory chronic spontaneous urticaria: real-life experience in Turkey.

Acta Dermatovenerol Alp Pannonica Adriat 2018 09;27(3):121-126

Department of Dermatology, Ada Tıp Hospital, Sakarya, Turkey.

Introduction: This study used real-world data to evaluate the effectiveness and reliability of omalizumab in treating recalcitrant chronic spontaneous urticaria in Turkish patients.

Methods: Study data were collected retrospectively from eight tertiary-care hospitals in Turkey. This study included 132 patients with chronic spontaneous urticaria that were resistant to H1 antihistamine treatment in a dose up to four times the licensed dose and were treated with 300 mg/month of omalizumab for 6 months.

Results: The mean weekly urticarial activity score (UAS7) after omalizumab treatment improved significantly compared to the pre-treatment score (p < 0.001). Treatment response was detected primarily in the 1st and 2nd months after treatment. No significant association was observed between omalizumab's treatment effectiveness and disease-related parameters or laboratory data. The mean dermatology life quality index was 23.12 ± 6.15 before treatment and decreased to 3.55 ± 3.60 6 months after treatment (p < 0.001). No side effects were reported in 89.4% (118) of the patients.

Conclusions: This study showed that UAS7 decreased significantly and quality of life improved in omalizumab-treated patients. Moreover, treatment effectiveness was mainly observed in the first 2 months after treatment. However, no association was observed between omalizumab treatment effectiveness and disease-related parameters or laboratory data.

Advanced oxidation protein products and serum total oxidant/antioxidant status levels in rosacea.

Postepy Dermatol Alergol 2018 Jun 18;35(3):304-308. Epub 2018 Jun 18.

Department of Biostatistics, Faculty of Medicine, Eskişehir Osmangazi University, Eskisehir, Turkey.

Introduction: Rosacea is a chronic, inflammatory dermatosis which develops due to the effect of genetic and environmental factors.

Aim: To evaluate the oxidative stress in rosacea patients by measuring serum total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI) and advanced oxidation protein products (AOPP) levels in our study.

Material And Methods: Our study included rosacea patients and healthy volunteers aged between 18 and 65 years. Total antioxidant status, TOS and AOPP levels were measured and OSI was calculated.

Results: The study included 70 rosacea patients and 30 healthy volunteers as a control group. When TAS, TOS, OSI and AOPP levels were compared between rosacea and control groups, there was no difference for OSI levels; while TAS, TOS and AOPP levels were significantly higher in the rosacea group ( = 0.151, = 0.013, = 0.034, = 0.017, respectively). In the rosacea group, there was no correlation between TAS, TOS, OSI and AOPP levels and disease duration. Besides there was no difference between family history, rosacea type, symptom frequency and ocular involvement and TAS, TOS, OSI and AOPP levels in the rosacea group.

Conclusions: We observed that serum TAS, TOS and AOPP levels were significantly higher in rosacea patients, but there was no significant difference among the disease activity parameters. These results can support the role of oxidative stress in the pathogenesis of rosacea.

The Evaluation of Contact Sensitivity with Standard and Cosmetic Patch Test Series in Rosacea Patients.

Ann Dermatol 2018 Jun 23;30(3):290-295. Epub 2018 Apr 23.

Department of Biostatistics, Eskişehir Osmangazi University Faculty of Medicine, Eskisehir, Turkey.

Background: Rosacea is a common dermatosis characterized by erythema, telangiectasia, papules and pustules.

Objective: We aimed to evaluate contact sensitivity in the rosacea patients.

Methods: We included 65 rosacea patients and 60 healthy volunteers in the study. The patient and control groups were patch tested with European baseline series and cosmetic series.

Results: A positive reaction to at least 1 allergen in the European standard series was found in 32.3% of rosacea patients and 20.0% of subjects in the control group while the relevant numbers were 30.8% of rosacea patients and 10% of controls with the cosmetic series (=0.08). In total, we found a positive reaction to at least 1 allergen in 38.5% of patients and 25.0% of controls (=0.15). We did not find a statistically significant relationship between a positive reaction to 1 allergen in total and the gender, skin type, rosacea type, ocular involvement, age and disease duration. There were more symptoms in patients with a positive reaction to allergens (<0.001).

Conclusion: Contact sensitivity was detected more common in rosacea patients. Patch testing may be useful in the treatment and follow up of rosacea patients especially if symptoms such as itching, burning and stinging are present.

The efficacy and safety of phototherapy in geriatric patients: a retrospective study.

An Bras Dermatol 2018 Jan-Feb;93(1):33-38

Department of Dermatology, Faculty of Medicine, Eskisehir Osmangazi University, Eskişehir, Turkey.

Background: While phototherapy is a well-established treatment for many dermatoses, data from the literature regarding its use in elderly patients are quite limited.

Objective: In this study, we aimed to determine the phototherapy indications in geriatric patients and to evaluate the effectiveness and reliability of phototherapy in this group.

Methods: This study included 95 patients of 65 years of age and older who were treated in our phototherapy unit between 2006 and 2015. The data for this study were collected retrospectively from patient follow-up forms in the phototherapy unit.

Results: Phototherapy was administered to 28 (29.5%) patients for mycosis fungoides, 25 (26.3%) patients foplaque type psoriasis, 12 (12.6%) patients for palmoplantar psoriasis, 12 (12.6%) patients for generalized pruritus, and 18 (19%) for other dermatoses. Of the patients, 64.2% had received a narrowband UVB (NB-UVB), 21.1% oral psoralen UVA (PUVA), and 14.7% local PUVA treatment. A complete response was achieved in 76.9-85.7% of the mycosis fungoides and in 73.71-100% of the psoriasis vulgaris patients treated with NB-UVB and PUVA, respectively. All the patients with generalized pruritus were treated with NB-UVB, and 80% of these patients achieved significant improvement. The erythema rate was found to be 0.43% per session for NB-UVB treatment and 0.46% per session for PUVA treatment as a side effect.

Study Limitations: The limitations of our study are that it was retrospective and the remission durations of the patients are not known.

Conclusion: This study showed that phototherapy is effective and reliable in the elderly population with proper dose increases and close follow-up.

Morphea in Middle Anatolia, Turkey: a 5-year single-center experience.

Postepy Dermatol Alergol 2017 Aug 1;34(4):334-338. Epub 2017 Aug 1.

Department of Dermatology and Venereology, Faculty of Medicine, Eskisehir Osmangazi University, Eskisehir, Turkey.

Introduction: Morphea, also referred to as localized scleroderma, is a rare fibrosing skin disorder of undetermined cause.

Aim: We report our single-center experience with morphea.

Material And Methods: The study included 53 patients who were diagnosed with morphea by histopathology in our department between 2010 and 2015. Study data were collected retrospectively from the records of morphea patients.

Results: The study included 53 patients (38 women, 15 men), and median age at onset was 39.0 (range: 8-85) years. Thirty (56.6%) patients had circumscribed morphea, 15 (28.3%) had generalized morphea, and 7 (13.2%) had linear morphea. One patient had mixed variant morphea (generalized, pansclerotic and linear morphea). ANA positivity was detected in 12 (22.6%) patients, but analysis for an association between the presence of ANA and morphea types, patients' characteristics did not reveal any significant associations. We did not observe any extracutaneous manifestations in patients during follow-up period. There were 2 of 53 patients who had concomitant autoimmune disorder including vitiligo and spondyloarthritis. Thirty (56.6%) patients received only topical treatment. The patients with clinical improvement who were treated with systemic therapy received methotrexate (26.4%), colchicine (9.4%), mycophenolate mofetil (5.7%) and prednisolone (1.9%).

Conclusions: Our results related to the demographic data of the patients and morphea types were consistent with the literature. On the other hand we observed that methotrexate was mostly used as an effective treatment option for generalized morphea.

Kaposi's sarcoma concealed by stasis dermatitis in a patient with psoriasis.

Acta Dermatovenerol Alp Pannonica Adriat 2017 09;26(3):69-71

Department of Pathology, Eskisehir Osmangazi University, Eskisehir, Turkey.

Kaposi's sarcoma (KS) is a multifocal and angioproliferative neoplasm. KS may be accompanied by psoriasis; however, in most of these cases the main mechanism involves iatrogenic KS associated with the immunosuppressive drugs that are used in psoriasis treatment. In angioproliferative lesions as a result of venous insufficiency and stasis dermatitis, acroangiodermatitis (pseudo-KS) is initially considered. However, the concurrent occurrence of psoriasis, stasis dermatitis, and KS has not been previously reported. We report a case of classic-type KS in an 83-year-old man that was concealed by stasis dermatitis and accompanied by psoriasis.

The role of irisin in the relationship between psoriasis and insulin resistance.

G Ital Dermatol Venereol 2018 Aug 22;153(4):477-482. Epub 2016 Sep 22.

Department of Biostatistics, Faculty of Medicine, Eskişehir Osmangazi University, Eskişehir, Turkey.

Background: Irisin, a hormone like myokine, is identified to the relation with insulin resistance and metabolic syndrome recently. In the literature to date, there are no studies evaluating serum irisin levels in psoriasis patients. We aimed to elucidate the pathogenesis of insulin resistance in psoriasis patients by evaluating serum irisin levels and metabolic parameters associated with insulin resistance in patients with plaque-type psoriasis vulgaris.

Methods: The study included 40 patients with moderate-to-severe chronic plaque-type psoriasis vulgaris and 37 healthy subjects. Body Mass Index (BMI) and waist circumference were measured, and serum irisin, fasting blood glucose (FBG), lipid profile, high-sensitivity CRP (hs-CRP) and insulin levels were assessed. To evaluate insulin resistance, the Homeostasis Model Assessment (HOMA-IR) and triglyceride/HDL (TG/HDL) ratio were used.

Results: Serum irisin and HDL levels were significantly lower in patients than the control group (P<0.001, P=0.024). Within the patient group, there was a significant negative correlation between serum irisin and serum TG, LDL, and TG/HDL levels (P=0.041, P=0.022, P=0.025), and a positive correlation with HDL levels (P=0.036). The PASI scores and serum irisin levels were significantly positively correlated.

Conclusions: In conclusion, we observed that serum irisin levels were significantly lower in patients with psoriasis, and associated with serum lipid levels and disease activity in our study. These results can be interpreted that irisin is involved in the disease pathogenesis of patients with psoriasis in relation to metabolic dysregulation.

Polytetrafluoroetylene tape as temporary restorative material: a fluid filtration study.

J Istanb Univ Fac Dent 2015 21;49(3):17-22. Epub 2015 Oct 21.

Department of Endodontics, Faculty of Dentistry, Selçuk University, Turkey.

Purpose: The purpose of this study was to compare the sealing ability of temporary restorative materials at 24 hrs and 1 week.

Materials And Methods: Endodontic access cavities were prepared in 56 extracted lower incisor-teeth and divided into 5 groups (n=10). Standard 5 mm deep access preparations were completed and root canals were prepared to size ISO #30 file. The access cavities were restored as follows: Group 1: temporary restorative material (Ceivitron); Group 2: glass ionomer cement (Fuji II); Group 3: zinc oxide-eugenol cement (IRM); Group 4: zinc phosphate cement (Adhesor); Group 5: polytetrafluoroetylene tape (PTFE). The quality of the coronal sealing of each specimen was measured (24 hrs and 1 week) using fluid transport model. The data was analyzed with repeated measurements ANOVA, Tukey' HSD and Paired samples T-Tests.

Results: A significant difference was found among the groups at all time-periods (p<0.05). At 24 hrs, PTFE showed similar leakage with Ceivitron, IRM, and Fuji II but it showed higher leakage than Adhesor. At 1 week, Ceivitron showed higher leakage than PTFE, meanwhile PTFE showed similar leakage with IRM, Fuji II, and Adhesor (p>0.05). Sealing ability of IRM and PTFE groups significantly increased by time (p<0.05 and p<0.001 respectively).

Conclusion: Within the limitations of this study, PTFE showed an acceptable short-term sealing capability when compared to the other commonly used temporary restorative materials at 1 week measurements.

A rare variant of pilomatricoma: pseudobullous pilomatricoma.

Acta Dermatovenerol Alp Pannonica Adriat 2015 ;24(3):59-60

Department of Dermatology, Ahi Evran University, Kırşehir, Turkey.

Pilomatricoma (PM; calcifying epithelioma of Malherbe) is a benign tumor originating from the matrix of the hair follicles. Clinical types of the tumor are familial, perforating, multinodular, exophytic, anetodermic, and giant PM. The bullous type is seen only in 3 to 6% of cases. Because the bullous areas detected in PM are filled with lymphatic liquid, some authors use the term pseudobulla. This report presents a 26-year-old female patient that was diagnosed with pseudobullous PM based on clinical, radiologic, and histopathological findings, and the pathogenesis of the bullous appearance of PM is reviewed from the literature.

Effects of chelating agents on the mineral content of root canal dentin.

Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2011 Dec 19;112(6):e149-54. Epub 2011 Oct 19.

Department of Endodontics, Faculty of Dentistry, Selcuk University, Konya, Turkey.

Objective: The objective of this in vitro study was to assess the effect of several chelating agents on the mineral content of root dentin.

Study Design: Extracted human mandibular incisor roots were prepared and divided into groups according to the following irrigation protocols: 1) 17% ethylenediaminetetraacetic acid (EDTA); 2) 10% citric acid solution; 3) 18% etidronate; 4) 2.25% peracetic acid; 5) and deionized water (control). Dentin chips were obtained (Gates-Glidden nos. 3, 4, and 5). The levels of different minerals were analyzed with the use of inductively coupled plasma-atomic emission spectrometry (ICP-AES).

Results: 1) Peracetic acid significantly decreased P, K, Mg, Na, and S levels compared with the other groups (P < .05). 2) S decreased by different levels in all of the chelating solutions (P < .05), and the greatest decrease was observed in peracetic acid. 3) Ca levels significantly decreased in peracetic acid, citric acid, and EDTA (P < .05). 4) Mn levels significantly decreased in the citric acid and peracetic acid groups (P < .05). 5) Na and Zn levels significantly decreased in the peracetic acid, citric acid, and etidronate groups (P < .05).

Conclusions: The chelation agents can create different effects on mineral contents of root dentin, so it is important to know what effects each solution will have on root dentin before their clinical use. In addition, according to the results of this in vitro study, it might be recommended that peracetic acid, in particular, should be used with caution.
