BACKGROUND The contribution of platelets to the inflammatory response via several platelet derived mediators is well recognized. The role of mean platelet volume (MPV) in infectious and inflammatory disorders, however, has not yet been well-established. While some of the previous studies demonstrated that MPV acted as a positive acute phase reactant,(More)
BACKGROUND The aetiology of chronic urticaria is usually considered idiopathic. There is a paucity of research both on the prevalence of Helicobacter pylori infection in the aetiology of chronic spontaneous urticaria (CU) in children and also on which patients H. pylori should be investigated. METHODS All paediatric and adult patients who presented to the(More)
Vitamin D has been linked with immunity, and the immunomodulatory role of this molecule in regulating key elements of the immune system has become an area of intense scientific investigation. We designed a case–control study to investigate whether neonates with early-onset neonatal sepsis (EONS) had lower levels of vitamin D. The primary exposure for the(More)
Early-onset neonatal sepsis (EONS) continues to be a severe condition associated with a high mortality and morbidity. However, symptoms and laboratory markers of this serious condition are nonspecific and currently there are no available standard tests to provide perfect diagnostic accuracy. An early recognition and initiation of antimicrobial therapy are(More)
A 3,240-g infant was born at 38 weeks’ gestation to a 31-year old gravida 3 para 2 mother who received regular prenatal care. The pregnancy was uneventful except for right sided hip pain in the late third trimester, although the ultrasound scans were unremarkable. The infant was delivered by normal spontaneous vaginal delivery. Upon delivery, the infant was(More)
A 3200 g male infant was born at 40 weeks gestation to a 40-year-old gravida 4, para 3 mother. Pregnancy was uneventful and the infant was born via normal spontaneous vaginal delivery. The infant developed marked respiratory distress upon delivery and the heart rate remained below 100/min, for which the infant received positive pressure ventilation for 30(More)
Periodic fever syndromes are a group of disorders sharing similar symptoms, characterized primarily by regularly recurring fevers. PFAPA syndrome, one of the members of this group of disorders, is a clinical entity of unknown etiology which is frequently seen in the early childhood. Currently, the pathogenesis and the genetic basis of most of the disorders(More)
BACKGROUND There are no studies on clinically significant transaminase elevation due to rotavirus gastroenteritis in the literature. Also, there are significant discrepancies among previous studies regarding the prevalence of increased serum transaminase levels in rotavirus infection. METHODS Patients investigated for rotavirus by stool antigen testing,(More)
BACKGROUND Previous studies have shown that platelets are involved in the inflammatory process. Mean platelet volume (MPV) has been frequently used as an inflammatory marker in various diseases associated with inflammation. The role of MPV in children with chronic spontaneous urticaria (CU), however, has not yet been evaluated. In this study we compared MPV(More)
