Evaluation of Epidemyological Profile of Dupuytren’s Disease in Thrace, an Agricultural Region

Aim:Dupuytren's disease is a benign fibroproliferative disease that effects the palmar fascia on the palmar surface of the hand. Pathogenesis of the disease hasn’t been defined clearly yet but heredity, age, gender, alcohol consumption, liver disease, diabetes, smoking, drug ssuch as barbiturats, trauma and occupation that exposed to repetitive trauma were associated with.Materials and Methods:In our retrospective study, records of 91 patients who lived in Thrace region, a large agricultural area, operated for dupuytren's disease in Edirne State Hospital and Namık Kemal University Hospital between 2013 and 2018 were evaluated and demographic analysis was performed.Results:Dupuytren's disease has been seen more in males and has shown more in the sixth decade. It was more commonly observed in the dominant right hand. Premorbid disease and conditions like smoking, alcohol, and diabetes were present in most of the patients. 71 patients were agricultural workers or farmers dealing with agriculture. 78 patients have been living in the Thrace region for least 3 decade.Conclusion:We observed that, a large majority of Dupuytren’s disease patients in the Thrace region have been engaged in agriculture for prolonged periods of time. The incıdence of the disease was very high in people doing heavy labor and working as agricultural workers. Chronic diseases, like diabetes was not associated with increased incidence of Dupuytren’s disease. Thrace region is an agricultural geography and we aimed to draw attention to the relation between occupational risk factors and development of Dupuytren’s disease

Strengthening with steel wire mesh of ınfill wall in rc frames

Literatürde güçlendirme için farklı yöntemler mevcuttur. Bu çalışma kapsamında “Dolgu duvarların hasır çelik donatılı özel sıva ile güçlendirilmesi” yöntemi incelenmiştir. Bu amaçla, 4 adet aynı yapısal özelliklere sahip betonarme çerçeve üretilmiştir. Bu numunelerden bir tanesi yalın halde bırakılırken, diğer üçünün açıklığı dolgu duvar ile örülmüştür. Tuğla dolgu duvarlı betonarme çerçevelerden iki tanesi, duvar yüzeyine tek taraflı olarak uygulanan hasır donatılı sıva ile güçlendirilmiştir. Güçlendirilen iki numunede ankraj aralığı ve işçiliği değiştirilmiştir. Elde edilen sonuçlardan yapılan güçlendirmenin elemanın yük taşıma kapasitesi yanında enerji tüketme kapasitesini de artırdığı görülmüştür. Yanal yük taşıma kapasitesi açısından dolgu duvarlı numunede %120, seyrek ankraj ile güçlendirmede %160 ve sık ankraj ile güçlendirmede %180 yalın numuneye göre artış sağlanmıştır. Ankraj işçiliği kötü olan numunede güçlendirme yüzeyinin deney sırasında dolgu duvardan ayrıldığı görülmüştür. Güçlendirmenin tek taraflı yapılması nedeniyle güçlendirme uygulanmayan yüzeyde hasar X şeklinde ortaya çıkmıştır. Bu nedenle güçlendirmenin, duvarın tek tarafından ziyade her iki yüzünde de yapılmasının davranış açısından daha uygun olacağı düşünülmektedir

Naiv hepatit C enfeksiyonlu hastaların on-altı yıllık prognozu

Objectives: In this study, we aimed to evaluate the clinical course of treatment-naive patients infected with hepatitis C virus (HCV) who were followed up in various centers in Turkey. Materials and Methods: This was a retrospective study performed with the participation of 15 centers. Patients aged 18 years and older with HCV infection were included. Results: A total of 391 treatment-naive patients infected with HCV were included in this study. During the follow-up period, the final values of alanine aminotransferase, aspartate transaminase, and total protein were significantly decreased when compared to the initial values (p<0.001, p<0.001, and p=0.005, respectively). In the study group, 19.2% of the patients underwent liver biopsy and 4.1% underwent transient elastography (FibroScan). An increased histological activity index (HAI) score and fibrosis in the second biopsy were observed in one patient, only increased HAI in two patients and increased fibrosis in one patient, as shown on the FibroScan. In the 16 years of the study period, cirrhosis was radiologically detected in only one patient. Conclusion: Even if rapid progression is not observed, close monitoring of the clinical findings related to liver failure and fibrosis with invasive or non-invasive methods may be useful.Amaç: Bu çalışmada ülkemizin çeşitli merkezlerinde takip edilen naiv hepatit C virüs (HCV) ile enfekte hastaların klinik seyrini değerlendirmeyi amaçladık. Gereç ve Yöntemler: Bu çalışma retrospektif olarak 15 merkezin katılımıyla gerçekleştirilmiştir. Çalışmaya 18 yaş üstü, HCV enfeksiyonu olan hastalar dahil edilmiştir. Bulgular: Çalışmada 391 tedavi-naiv HCV enfeksiyonlu hasta yer almıştır. Hastaların takip süresinde son alanine aminotransferase, aspartate transaminase ve total protein değerleri ilk düzeyine göre önemli düzeyde azalmıştır (sırasıyla p<0,001, p<0,001, p=0,005). Çalışma grubunda hastaların %19,2’sine karaciğer biyopsisi, %4,1’ine elastografi (FibroScan) uygulanmıştır. Takip esnasında bir hastada ikinci biyopside histolojik aktivite indeksi (HAI) ve fibroziste artma, iki hastada sadece HAI’da artma, birinde FibroScan ile fibrozis değerinde artma olduğu gözlenmiştir. Bir hastada 16 yıl içinde radyolojik olarak siroz saptanmıştır. Sonuç: Hızlı progresyon gözlenmemekle birlikte hastaların izleminde karaciğer yetmezliği ile ilgili klinik bulguların ve invaziv veya noninvaziv yöntemlerle fibrozisin yakın takibi yararlı olabilir

Evaluation Of Epidemyological Profile Of Dupuytren's Disease in Thrace, An Agricultural Region

Amaç: Dupuytren hastalığı elin palmar yüzeyinde palmar fasyayı tutan benign fibroproliferatif bir hastalıktır. Patogenezi hala net olarak tanımlanmasa da heredite, yaş, cinsiyet, alkol kullanımı, karaciğer hastalıkları, diabet, sigara, barbiturat gibi ilaçlar, tekrarlayıcı travmaya maruz kalınan meslekler ile ilişkilendirilmiştir. Klinik gözlemlerimizde hastalığın tarım sektöründe çalışan işçilerde sık olduğu izlenmiştirMateryal ve Metot: Retrospektif çalışmamızda bir tarım bölgesi olan Trakya bölgesinde yerleşik, 2013- 2018 yılları arasında Edirne Devlet Hastanesi ve Namık Kemal Üniversitesi Tıp Fakültesi Uygulama ve Araştırma Hastanesinde Dupuytren hastalığı nedeniyle opere ettiğimiz 91 hastanın kayıtları incelenerek demografik analizleri yapılmıştır.Bulgular: Dupuytren hastalığı daha çok erkeklerde görülmüş olup, altıncı dekatta daha çok kendini göstermiştir. Dominant el olan sağ elde daha sık olarak görülmüştür. Sigara, alkol ve diabet gibi premorbid durum ve hastalıklar, olgularımızın bir kısmında görülmektedir. 71 hasta tarım işçisi yada tarım ile uğraşan çiftçi olduğu görülmüştür. Yetmiş sekiz hasta en az üç dekat Trakya bölgesinde ikamet eden ve yaşayan hastalar olduğu tespit edilmiştir.Sonuç: Çalışmamızda, Trakya bölgesinde görülen dupuytren hastalığı olgularının oldukça büyük bir çoğunluğunun uzun bir süredir tarım ile uğraştığını gördük. El işçiliği ve bölgesel tarım işçiliğinin hastalıkla birlikte görülme sıklığının yüksek olduğu izlenmiştir. Bu hastaların birçoğunda diabet gibi kronik hastalıkların bulunmadığı tespit edilmiştir. Ülkemizde Trakya bölgesi tarım coğrafyası olup mesleki risk faktörlerine dikkat çekilerek literatüre katkı sağlamak amaçlandı.Aim: Dupuytren's disease is a benign fibroproliferative disease that effects the palmar fascia on the palmar surface of the hand.

Fracture resistance of root-filled teeth after cavity preparation with conventional burs, Er: YAG and Er,Cr: YSGG lasers

Purpose The aim of the present study is to compare the fracture resistance of teeth after access cavity preparation with conventional rotary burs, Erbium-doped yttrium aluminum garnet laser (Er:YAG) and Erbium, cromium: yttrium scandium gallium garnet laser (Er,Cr:YSGG) lasers. Materials and methods Fifty five intact mandibular molars were divided into 3 negative groups (groups 1, 2, 3; n=5 for each), 3 study groups (groups 4, 5, 6; n=10 for each) and 1 positive control group (intact teeth; n=10). Access cavities of groups 1, 2 and 3 were prepared with conventional burs, Er:YAG laser and Er,Cr:YSGG laser respectively. After root canal obturation, their coronal portions were left non-restored. Access cavities of groups 4, 5 and 6 were prepared by using the same equipment but their coronal portions were restored with composite resinafter root canal obturation. Following thermocycling, fracture strength was evaluated with a Universal Testing Machine. Mean force at which each sample is fractured was recorded in Newton unit and statistically analyzed. Results Fracture resistance of group 7 (intact teeth) was significantly higher than all other groups (p<0.001). Differences among the fracture resistance values of groups 4, 5 and 6 were not significantly different but they were significantly higher than those of groups 1, 2 and 3 (p<0.001). No significant difference was found between Groups 1, 2 and 3. Conclusion Preparing access cavities with either laser or bur has no effect on the fracture resistance of teeth with root canal treatment

Experimental performance comparison of a 2-axis sun tracking system with fixed system under the climatic conditions of Duzce, Turkey

WOS: 000378097800078In this study, an experimental performance comparison of a 2-axis tracking system with a fixed panel in a solar renewable energy system is conducted. The paper mainly focuses on a cost benefit analysis of fixed and tracking modules. For this aim, an experimental setup was built and periodical measurements were then obtained from the setup. To provide a better comparison, the panels were exposed to the same conditions during the measurements. By considering the real-time experimental results, the paper provides a quantitative analysis of the feasibility of tracking panels for domestic applications as well as an analysis of payback period if a tracking system is used for a home-building application instead of using a conventional fixed module. The study is restricted to the geographical region of Duzce, Turkey.Scientific Research Project Commission of Duzce University [2013.06.03.173]This study was supported in part by the Scientific Research Project Commission of Duzce University (Grant No. 2013.06.03.173)
