Analysis of Patients Who Present to Emergency Departments During Ramadan

INTRODUCTION: Fasting is one of the five basic obligations of Islam. Muslims fast during the month of Ramadan according to the lunar calendar. Fasting during Ramadan involves abstinence from food and drinks from sunrise to sunset. The present study investigated the effect of fasting during Ramadan in patients who presented to emergency departments. Results of this study may guide healthcare authorities in countries that provide health services to Muslim communities because of increased migration. MATERIAL AND METHODS: This is the first prospective multicentre study to examine emergency department applications for Ramadan. The study was performed between 05.26.2017 and 06.24.2017. Patients were classified according to cardiopulmonary complaints, trauma-associated complaints, neurological complaints, gastrointestinal complaints, headache, renal colic, upper respiratory tract complaints, and malaise. Vital signs, age, gender, presentation type, complaint type, hospital stay duration, requested laboratory examination, radiological examination, treatment outcomes, application time, smoking status, and fasting status of the study patients were recorded by using a questionnaire. RESULTS: Fasting and non-fasting patients showed a significant difference with respect to presentation type, gastrointestinal complaints, upper respiratory tract complaints, hospitalization status, requested radiological and biochemical examinations, hospitalization duration, and application time (p < 0.05). CONCLUSIONS: To the authors’ knowledge, the present study is the first to compare the complaints of fasting and non-fasting patients during Ramadan. The authors feel that this study is superior to several previous studies because it has been performed using a different perspective and provides more accurate and objective data than those reported in previous studies

Evaluation of Postoperative Pain After Using Different File Systems: A Randomized Clinical Study

Objectives: This study evaluated the effect of instrumentation techniques on the postoperative pain after single-visit root canal treatment. Materials and Methods: Sixty patients having an indication of endodontic treatment were included. Only single rooted teeth were selected The patients were randomly divided into 2 groups. In group 1; the root canals were instrumented using ProTaper Next instruments with rotational motion, in group 2 TF Adaptive instruments with adaptive motion were used during instrumentation. Treatments were completed in a single appointment. Postoperative pain questionnaires were scored by patients using a four-point pain intensity scale for 12, 24, and 48 hours. Mann Whitney-U, Friedman and Wilcoxon tests were used for analyzing the final data. Results: The comparison of time intervals between groups demonstrated no difference between both groups (p>.05). In both groups, the postoperative pain values of 12h time period were significantly higher than both other periods, and significant difference was found between 24h and 48h time periods (p<0.05). The postoperative pain values of 48h time period were significantly lower than the other two time periods (p<0.05). Conclusions: Both instrumentation techniques caused postoperative pain. The pain scores indicated that both techniques caused limited discomfort associated with slight pain which did not require any additional treatment and medication

Comparison of the Shear Bond Strengths of Ceramic Brackets Using Either a Self-Etching Primer or the Conventional Method after Intracoronal Bleaching

Objective:To evaluate the initial shear bond strengths (SBSs) of ceramic brackets using either a self-etching primer (SEP) or the conventional method (CM) after intracoronal bleaching with sodium perborate and distilled water.Methods:Eighty human incisors were divided into four groups according to bleaching and bonding procedures: Group 1, bleaching was not applied and the brackets were bonded with a self-etching primer; Group 2, bleaching was not applied and the brackets were bonded with the conventional method; Group 3, intracoronal bleaching with sodium perborate was applied for three weeks and the brackets were bonded with a self-etching primer; and Group 4, intracoronal bleaching with sodium perborate was applied for three weeks and the brackets were bonded with the conventional method. A self-etching primer (Transbond Plus) was applied as recommended by the manufacturer. After SEP application, the ceramic brackets were bonded with a light-curing adhesive (Transbond XT). For the conventional method, the teeth were etched with 37% phosphoric acid. After etching, a thin uniform coat of primer (Transbond XT Primer) was applied and the ceramic brackets were bonded with a light-curing adhesive (Transbond XT). SBSs were measured after water storage for 30 days, after 1000 cycles of thermocycling between 5°C and 55°C. Bond failure location was determined with the Adhesive Remnant Index (ARI).Results:For the SEP method, there was no significant difference between SBS values of the bleaching and non-bleaching groups. Furthermore, for the conventional method, the SBS value of the non-bleaching group was not significantly different from that of the bleaching group. SBS values of the SEP method presented significant differences from those of the conventional method (p<0.001). SBS values of SEP application decreased with and without bleaching. The ARI scores did not show any significant difference among the groups (p=0.174).Conclusion:Intracoronal bleaching with sodium perborate and distilled water did not affect the SBS values of ceramic brackets

Research population constitutes 54 Science and Technology teachers in the all state secondary schools attached to the Ministry of Education in Çankırı in 2013-2014 academic year. The sampling path was not used in the research so “self-sampling universe” was adopted as the study universe. Data were collected through a survey that consist of five questioned-first part that contains teachers’ personal information, eighty-questioned second part that contain their views on teachers’ time management strategies. Second part questions consist of Likert-type (classification) questions. In the analysis of data, t-test and Mann-Whitney U test techniques were used for differences by gender of teachers; one-way analysis of variance (one-way Annova-F test), Kruskal-Wallis H test techniques were used for their seniority and differ from the actual class they teach. According to the research findings; Despite significant differences in Science and Technology teachers, a significant difference was found between their time management strategies. So it can be said that teachers use similar time management strategies in courses. A significant difference between the averages of opinions could not be found between professional seniorities of Science and Technology teachers and time management approach of teachers as Get Yourself Together, Warrior, Goal, Magic Tools, Cut Adrift Yourself, Self-Conscious Approaches. Despite this, a significant difference between the average of opinions was found between professional seniorities of Science and Technology teachers and their ABC and Time Management 101 Approaches. It can be said that, class sizes tought by the Scince and Technology teachers, do not effect to use levels of Get Yourself Together, Warrior, Magic Tools, Time Management 101, Cut Adrift Yourself, SelfConscious Approaches. Despite this, a significant difference between the average of opinions was found between class sizes tought by the Scince and Technology teachers and Goals and ABC Approaches within the time management approaches

Evaluation of the physical and emotional effects of the COVID-19 pandemic on patients with fibromyalgia and chronic low back pain: A multicenter cross-sectional controlled study

Objectives: This study aimed to investigate the physical and emotional effects of the coronavirus disease 2019 pandemic in patients with fibromyalgia syndrome (FMS) and chronic low back pain (CLBP) patients.Patients and methods: The cross-sectional controlled study was performed with 1,360 participants (332 males, 1,028 females; mean age: 42.3 +/- 12.5 years; range, 18 to 65 years) between September 2020 and February 2021. The participants were evaluated in three groups: the FMS group (n=465), the CLBP group (n=455), and the healthy control group (n=440). Physical activity, pain levels, and general health status before and during the pandemic were evaluated in all participants. Stress levels were analyzed with the perceived stress scale (PSS) in all groups, and disease activity was analyzed with the fibromyalgia impact questionnaire (FIQ) in patients with FMS.Results: Patients with FMS had worsened general health status and pain levels during the pandemic compared to the other groups (p<0.01). The FMS group showed significantly higher PSS scores than those in other groups (p<0.01). There was a weak-positive correlation between FIQ and PSS parameters in patients with FMS (p<0.05, r=0.385).Conclusion: The general health status, pain, and stress levels of the patients with FMS and CLBP tended to worsen during the pandemic. This high-stress level appeared to affect disease activity in patients with FMS

In Vivo Evaluation Of Biocompatibility Of Mineral Trioxide Aggregate And A Newly Developed Experimental Material

Mineral Trioksit Agregat (MTA) kök ucu dolgusunda, pulpa kaplamasında, perforasyon tamirinde ve diğer endodontik tedavi işlemlerinde yaygın olarak kullanılmaktadır. MTA ve yeni geliştirilen deney materyalinin benzer kimyasal ve fiziksel özelliklere sahip olduğu bilinmektedir. Bu çalışmanın amacı, MTA ve yeni geliştirilen deney materyalinin biyouyumluluklarının değerlendirilmesidir. 21 Sprague Dawley (SD) cinsi rat, üç deney grubuna ayrıldı. Grup 1 ve Grup 2 sırasıyla ProRoot MTA ve deney materyalini içermektedir. Materyaller distile su ile karıştırıldı ve teflon tüplere yerleştirildi. Tüpler hayvanların sırt bölgesine subkutan olarak implante edildi. İmplante edilen tüplerin boş bırakıldığı Grup 3, kontrol grubu olarak ayrıldı. Tüplerin implantasyonunu takiben 7, 14 ve 28. günlerde hayvanlar feda edildi ve implantlar çevre dokularla birlikte çıkartıldı. Örnekler biyouyumluluklarının değerlendirilmesi amacı ile rutin histolojik inceleme için hazırlandı. Test materyallerine karşı doku reaksiyonlarında belirgin bir farklılık bulunmadı (Grup I ve II; p>0,05). Tüm zaman periyotlarında hem ProRoot MTA ve hem de yeni geliştirilen materyal implantlarına karşı birbirine yakın minimal iltihabi cevap gözlemlendi. Kontrol grubu da benzer sonuçlar gösterdi (p>0,05). MTA ve yeni geliştirilen materyal in vivo olarak değerlendirildiğinde karşılaştırılabilir biyouyumluluk gösterdi. Sonuç olarak yeni geliştirilen materyalin, ProRoot MTA&#8217;nın kullanılabildiği klinik durumlarda uygulanabilme potansiyeli olduğunu ortaya çıkartmıştır. Sonuçlar deney materyalini desteklemekle birlikte, materyalin güvenli klinik kullanımından önce daha fazla çalışmanın yapılması gerekmektedir.Mineral Trioxide Aggregate (MTA) is being widely used for root-end filling, pulp capping, perforation repairs and other endodontic procedures. MTA and a newly developed experimental material are known to have similar chemical and physical properties. The purpose of this study was to evaluate the biocompatibility of MTA and the new experimental material. Twenty one Sprague Dawley (SD) rats were allocated to testing of three groups. Group I and Group II included ProRoot MTA and the experimental material, respectively. The materials were mixed with distilled water and placed in polyethylene tubes. The tubes were implanted subcutaneously in the dorsal region of the animals. Group III served as control; the implanted polyethylene tubes remained empty. At 7, 14, and 28 days after the implantation, the animals were sacrificed and the implants were removed with the surrounding tissues. The specimens were prepared for routine histological examination to evaluate the inflammatory response. No significant difference was found between tissue reactions against the tested materials (Group I and II; p>0.05). Minimal inflammatory response was observed at either time period at sites adjacent to ProRoot MTA and the experimental material implants. Also ,control group showed similar results(p>0.05). MTA and the experimental material show comparable biocompatibility when evaluated in vivo. In conclusion, the results suggest that the experimental material has the potential to be used in clinical conditions in which ProRoot MTA is indicated. Although the results are supportive for the experimental material, more studies are required before the safe clinical use of the experimental material
