Endodontik-periodontal kombine kemik içi defektlerin tedavisinde trombositten zengin fibrin membran ile otojen kemik greftinin kombine kullanımı: olgu sunumu

<p>Platelet-rich fibrin (PRF) is a new generation product of blood sourced material. Its major advantages are ease of preparation, and that blood contents are not changed by biochemical processing which reinforce the product’s autogenous nature. In our study, a 51 years-old male patient attending to our clinic with endodontic- periodontal intraosseous defect was treated with PRF membrane combined with autogenous bone graft in addition to endodontic treatment demonstrated successful results in hard and soft tissue healing.</p> <p><strong> </strong></p> <p><strong>ÖZET</strong></p> <p>Trombositten zengin fibrin (TZF), kan kaynaklı maddelerin yeni jenerasyon ürünüdür. Yönteminin kolaylığı ve elde edilirken içeriğinin herhangi bir biyokimyasal işlemle değiştirilmemiş olması TZF’nin önemli bir artısı olup bu avantajlar ürünün otojen özelliğini pekiştirirler. Çalışmamızda, kliniğimize başvuran 51 yaşındaki erkek hastanın endodontik-periodontal kemik içi defektinde endodontik tedavinin yanı sıra TZF membran ile otojen kemik greftin kombine olarak kullanılması sert ve yumuşak doku iyileşmelerinde başarılı sonuçlar sergilemiştir.</p> <p><strong>Anahtar Kelimeler: </strong>Trombositten zengin fibrin (TZF), Otojen kemik grefti</p&gt

Light And Scanning Electron Microscopic Examination Of Hair In Griscelli Syndrome

Griscelli syndrome is a rare disease characterized by pigment dilution, partial albinism, variable cellular immunodeficiency, and an acute phase of uncontrolled T-lymphocyte, and macrophage activation. Griscelli et al described this syndrome in 1978. Since then, only in approximately 60 cases have been reported, most from the Turkish, and Mediterranean population. In microscopic examination, silvery gray hair with large, clumped melanosomes on the hair shaft is the diagnostic finding. Here, we present scanning electron microscopic study of hair in 2 cases of Griscelli syndrome, where the hair showed normal cuticular pattern but nodular structures were present as an abnormal findings.Wo

Morphometric Assessment Of Corpus Callosum And Cerebral Hemispheres With Magnetic Resonance Imaging

Objective: In this study, our purpose was to assess the relationship between handedness, footedness and the morphological differences of certain intracranial structures on MR images. Material and Methods: 63 healthy male and 52 healthy female individuals were included in the study. In each subject, 16 measurements of intracranial structures were taken on MR images. Area of corpus callosum, also left and right cerebral hemispheres, length of CC, width of genu (r1), truncus (r2), isthmus (r3) and splenium of CC (r4) and width of corresponding cerebral hemisphere were measured. Results: There was a statistically significant difference in R3 (width of the corresponding cerebral hemisphere to r3) distance between those using their right feet and those using their left feet. Angle of genu in right-handed people was greater in males than in females. Angle of genu in cases using the left foot was greater in females than in males for standing on one leg. Conclusion: Morphometric assessment of CC with MR imaging related to handedness and footedness may be useful in demonstrating the relationship between callosal morphology, gender differences and extremity preference in neuroscience.Wo
