Amaç: Bölgemizdeki kan grubu dağılımını bilmek ve gereksinim halinde bunu pratik ve bilimsel anlamda kullanmayı amaçladık. Yöntemler: 2012-2018 yılları arasında ............................................................. Kan merkezine kan bağışı amacı ile başvuran 123,900 sağlıklı bireyin kan grupları retrospektif olarak analiz edildi. Kan merkezimize başvuran kişilerin ABO ve Rh kan grupları mikroplak aglütinasyon veya kolon aglütinasyon yöntemleri ile tespit edilmiştir. Bulgular: 123.900 bireyin kan grubu analizi sonuçlarına göre; 47,496 (%38,3) kişi A Rh (+), 36,427 (%29,4) kişi O Rh (+), 16,294 (%13,2) kişi B Rh (+), 7,971 (%6,4) kişi AB Rh (+), 6,793 (%5,5) kişi A Rh (-), 5451 (%4,4) kişi O Rh (-), 2,560 (%2,1) kişi B Rh (-), 908 (%0,7) kişi AB Rh (-) olarak saptanmıştır. Rh kan grubu açısından bakıldığında 108,188 (%87,31) kişinin Rh (+) olduğu, 15,712 (%12,69) kişinin de Rh (-) olduğu görülmüştür. Sonuç: İstanbul ili demografik olarak Türkiye’nin özetini yansıtmaktadır. Bölgemizdeki kan grubu dağılımı oranları Türkiye geneli ve İstanbul bölgesi oranları ile benzerdi. Bununla birlikte diğer bazı bölgelerle farklılıkların da olduğunu gördük. Elde ettiğimiz bulguların kan grupları veritabanı açısından pratiğe ve literatüre faydalı olacağını düşünüyoruz.

Blood transfusion is the most frequently used and life-saving therapeutic procedure today. Transmission of virus, bacteria and parasitic microorganisms may occur due to transfusion (Transfusion transmitted infections-TTIs). Hepatitis B and C, human immunodeficiency virus (HIV) and syphilis (Treponema pallidum) bear the risk of transmission by transfusion. Hepatitis B surface antigen (HBsAg), anti-HCV, anti-HIV½ and syphilis antibody (VDRL: Venereal Disease Research Laboratory) are routinely controlled in all donated blood samples. The aim of the present study was to analyze the seroprevalence rates of blood donors through screening test results according to duration, age range and gender. Data of all blood donors obtained from blood Centre of Marmara University Pendik Training and Research Hospital between January 2013 and October 2018 were analyzed retrospectively. Serum samples of the donors were analyzed for HBsAg, anti-HCV, anti-HIV½ and VDRL. Test results of 114.240 donors were scanned. Gender, age range and distribution by years of these donors were analyzed. According to age distribution of donors were divided into 4 groups. There were 114.240 participants including 106.153 (92.9%) males and 8.087 (7.1%) females. The positivity rate of HBsAg was detected 0.4% (36/8087) in females and 0.5% (500/106.153) in males. The positivity rate of anti-HCV was detected 0.4% (32/8.087) in females and 0.3% (344/106.153) in males. The positivity rate of anti HIV½ was 0.1% (9/8.087) in females and 0.1% (92/106.153) in males whereas the positivity rate of VDRL was 0.5% (41/8.087) in females and 0.3% (362/ 106.153) in males. Positivity rate for HBsAg and HCV were lower in the cases between 18 and 30 years of age. The positivity rates for anti-HIV½ was not significantly different according to the age range. Positivity rate for VDRL was higher in the cases at 51 years of age and older. No difference was found between men and women in terms of HBsAg, anti-HCV and anti-HIV½positivity. However, VDRL test positivity was significantly higher in female participants. Furthermore, HBsAg, anti-HCV and VDRL positivity rates increased by age.

Background: Bronchiectasis is described as destruction and the irreversible dilatation of bronchial structure. We wanted to demonstrate our surgical practice and outcome of surgical treatment in bronchiectasis. Methods: We studied records of 60 pediatric patients who underwent surgical resection in our clinic between January 2000 and January 2013. The results were analyzed regarding factors influencing the outcome. Results: There were 32 boys and 28 girls with a mean age of 9.45 years (range 2–15). The most common cause was childhood infection in 25 (41.66%). The mean duration of the symptoms was 42.93 months. Patients underwent 64 operations including 2 staged thoracotomies and 2 re-thoracotomies. Atelectasis was the most frequent complication. Longer duration of symptoms related to postoperative complication. The morbidity and mortality rates were 20% and 3.33%, respectively. The outcome was optimal in 92%. Forced expiratory volume in 1 s less than 60% of the predicted value, hemoptysis and duration of symptoms were found prognostic variables for postoperative morbidity with high ratios of odds coefficients by using Binary Logistic Regression Method. Conclusions: Complete and early resection of bronchiectasis provides a successful outcome. Duration of symptoms and timely intervention have a major impact on the management and prognosis. Hintergrund: Bronchiektasen sind durch eine irreversible Dilatation und Strukturzerstörung der Bronchialwand definiert. Wir wollen unser chirurgisches Vorgehen und Langzeitergebnisse präsentieren. Patienten & Methodik: Wir untersuchten Datensätze von 60 pädiatrischen Patienten, die von Jänner 2000 bis 2013 einer chirurgische Resektion an unserer Klinik unterzogen worden waren. Wir evaluierten mehrere Variablen und deren Einfluss auf das postoperative Ergebnis. Ergebnisse: 32 Jungen und 28 Mädchen mit einem Durchschnittsalter von 9,45 Jahren (zwischen 2–15) wurden operiert. Die häufigste Ursache waren kindliche Infektionskrankheiten in 25 Fällen (42%). Die mittlere Dauer der Symptome betrug 43 Monate. Die Patienten wurden 64 Operationen, darunter 2 mehrzeitigen Thorakotomien und 2 Re-Thorakotomien unterzogen. Atelektasen waren die häufigste Komplikation. Die Symptomdauer korrelierte mit postoperativen Komplikationen. Die Morbidität und Mortalität waren 20% und 3,3%. Das Ergebnis wurde in 92% als optimal gewertet. Eine Einsekundenkapazität<60%, Hämoptysen und die Symptomdauer zeigten einen Zusammenhang zum postoperativen Ergebnis (erhöhte Odds Ratios in einer binären Regressionsanalyse). Schlussfolgerungen: Eine möglichst frühzeitige und komplette Bronchiektasenresektion führt zu guten Ergebnissen. Symptomdauer und zeitgerechte Intervention sind für Management und Prognose wichtig.

Platelet transfusion is used to prevent bleeding in patients with thrombocytopenia or platelet dysfunction. Purpose of investigating demographic characteristics of eligible volunteers as platelet donors and of demonstrating the association of platelet counts with blood groups as well as other factors. We used data of individuals who referred to a blood center in our hospital. Age, body weight, body mass index (BMI), and gender were determined, and than hemogram values such as leukocyte, hemoglobin, hematocrit, and platelet and ABO blood types of those individuals were identified. A statistically significant difference determined for height, body weight, and BMI in both genders. Although BMI was lower in the group of platelet count ≤ 250, it was higher in a group of platelet count > 250. Furthermore, platelet count was more moderate in blood group O Rh-positive but, no significant difference was group O Rh-negative. Platelet count was higher in other Rh-positive blood groups than Rh negatives. BMI is vital in apheresis donors, and individuals with higher BMI values may prefer in case of double dose or more apheresis need. The determination of platelet counts in Rh positives is more elevated than Rh negatives.
