The Prevalence of Tonsillar Human Papilloma Virus Infection in İstanbul, Turkey: A Human Cadaver Study

Objective:To investigate the prevalence of tonsillar human papillomavirus infection in İstanbul, the most populous city of Turkey.Methods:Tonsil specimens were obtained from 206 cadavers aged 18 to 89 years. Tonsillectomy was performed during routine autopsy for each subject in the 24 hours after death. After dissolution, tissues were processed with the polymerase chain reaction (PCR) method to identify HPV DNA. The data obtained from the DNA sequencer were processed in the database of GenBank®.Results:One hundred sixty-six (80.6%) male and 40 (19.4%) female cadavers were included in the study. One case demonstrated HPV-16, one had HPV-82, one had HPV-55 and one had HPV-13. All four cases were male. Prevalence of tonsillar HPV was 1.94% and of HPV 16 was 0.48%.Conclusion:The prevalence of tonsillar HPV infection was found 1.94% and of HPV 16 0.48% in our study

Strengthening of RC shear walls with CFRP strips

International Institute for FRP in Construction (IIFC)8th International Conference on Fibre-Reinforced Polymer (FRP) Composites in Civil Engineering, CICE 2016 -- 14 December 2016 through 16 December 2016 -- -- 137222The purpose of this study was to investigate the hysteretic behavior of shear deficient reinforced concrete (RC) walls that were strengthened with carbon fiber reinforced polymer (CFRP) strips. Totally, ½ scale five specimens with 1.5 aspect ratio walls were constructed. One of them was tested without any retrofitting as a reference specimen and four of them were retrofitted specimens with CFRP strips. All of the specimens were tested under cyclic lateral loading. CFRP strips with different configurations were tested like X-shaped, horizontal and parallel strips or combinations of them. All of the CFRP configurations were symmetrically bonded to both sides of the shear wall and were anchoraged to the wall. The research focuses on the effect of using CFRP strips for enhancing strength and increasing ductility of the non-seismic detailed shear walls. Test results shows that all of the CFRP strip configurations significantly improves the lateral strength, energy dissipation and deformation capacity of the shear deficient RC walls. The specimen that was strengthened with X-shaped CFRP strips was failed with premature shear failure. The specimen that was strengthened with horizontal strips was showed flexural hysteretic behavior and plastic hinge was developed at the wall base. CFRP strips were controlled shear crack propagation and resulted in improvement of displacement capacity.

Hysteretic behavior of RC shear walls strengthened with CFRP strips

WOS: 000313854200038The purpose of this study was to investigate the hysteretic behavior of shear deficient reinforced concrete (RC) walls that were strengthened with carbon fiber reinforced polymer (CFRP) strips.

Gallbladder perforation

Safra kesesi perforasyonları (SKP) klasik olarak üç tipte sınıflandırılmıştır: Tip I: Akut gelişir, safra peritonitiyle sonlanır, Tip II: Kapalı perforasyon sonucu perikolesistik ab-se veya subdiafragmatik abse gelişir, Tip III: Kronik olarak kolesistoenterik fistül gelişir. Bu retrospektif çalışmada Çukurova Üniversitesi Tıp Fakültesi Genel Cerrahi Anabilim Dalı'nda Ocak 1984-Nisan 1995 yılan arasında ameliyat edilen 23 safra kesesi perforasyonlu hasta bu klassifikasyona gö¬re sınıflandırıldı. Hastaların 16'sı (%69,5) kadın, yedi¬si (%30,5) erkek olup, ortalama yaş 53,9 (34-73) idi. Tip I dokuz (%39,2), Tip II sekiz (%34,8) ve Tip III altı (%26) hastada saptandı. Ek sistemik hastalıklar Tip II ve Tip III ile kıyaslandığında en fazla Tip Fde görüldü (p<0,05). Yedi (%30,5) hastaya kolesistekto-mi, 16 (%69,5) hastaya kolesistektomi +ilave cerrahi prosedürler uygulandı. On (%43,5) hastada postopera-tif komplikasyonlar gelişti. Komplikasyon gelişimi Tip I grubunda Tip II ve IIl'e göre anlamlı olarak yüksek bulundu (p<0,05) . İki (% 8,7) hasta erken postopera-tif dönemde sepsis nedeniyle kaybedildi. Ölen hastalar Tip I grubunda idi. Tip I SKP'lu hastalarda morbidite ve mortalite yüksek olduğu için hızlı preoperatif tanı ve tedavi gerekmektedir. Akut kolesistitte erken cerrahi girişimin SKP'larında tanıda gecikmeleri önleyerek morbidite ve mortalüeyi azaltacağı düşüncesindeyiz.Traditionally, gallbladder perforations are classified as either: Type I, acute free perforation with bile-stained peritoneal fluid; type II, subacute perforation with pericholecystic abscess; type III, chronic perforation with formation of cholecysto- enteric fistula. Between January 1984-April 1995 period In the department of General Surgery, Çukurova University, School of Medicine, 23 cases with gallbladder perforation were evaluated retrospectively. There were 16 (69.5%) female, seven (30.5 %) male and the median age was 53.9 (34-73). Type I in nine (39.2 %) cases, type II in eight (34.8 %) and type III in six (26%) were detected. The incidence of severe systemic diseases were more common in type I as compared others (<0.05). Cholecystectomy were performed in seven (30.5%) cases, cholecystectomy and additional surgical procedures in 16 (69.5%). Ten (43.5%) cases had developed postoperative complications. The complication rate was more common in type I as compared others (<0.05). In the early postoperative period, two (10%) cases died due to sepsis. They were also in type I cases. Type I having high morbidity and mortality rate, needs immediate pre-operative diagnostic approach. Early cholecystectomy for acute cholecystitis appears to reduce the morbidity and mortality due to a delay in diagnosis
