Biologically, Acute myeloid leukemia (AML) is highly heterogenous. AML with cup-like blast morphology variant has been reported to have important role in risk group stratification and treatment implications. In pediatric age group, this morphology and its clinical implication is rarely discussed. Although this morphology variant is not stated in World Health Organization (WHO) classification of...

The crosstalk between coagulation and inflammation and the propensity for microthromboembolic disease during sepsis calls for anticoagulant measures to prevent tissue hypoxygenation and to attenuate organ damage and dysfunction. Only one anticoagulant, recombinant human activated protein C (aPC, drotrecogin-alpha) has a proven survival benefit when used as an adjunctive therapy for human sepsis...

Background & Objective: Neonatal sepsis is one of the leading causes of mortality in neonatology wards. The aim of this study was to assess sepsis pathogens and antibacterial resistance patterns in a teaching hospital during seven years in Tehran, Iran. Methods: In this retrospective study, all neonates suspected to seps...

Neonatal sepsis is a life-threatening disease. Early diagnosis essential, but no single marker of infection has been identified. Sepsis activates coagulation cascade with simultaneous production the D-dimers due to lysis fibrin. D-dimer test reflects activation system.

Background: Neonatal sepsis is a life-threatening disease with an incidence of 1 to 10 per 1000 live births and a mortality rate of 15% to 50%. The clinical signs are non-specific and indistinguishable from those caused by a variety of neonatal noninfectious disorders. Objective: The aim of this study was to determine the importance of CD64 expression (FcgRI), a neutrophil surface marker, in ea...

prolonged cough occurs in a large proportion of the 2 million pilgrims who participate in the annual hajj in saudi arabia. there is no unique cause for pilgrims’ respiratory involvement, but several studies suggest a high incidence of influenza as a cause of the disease. to determine influenza vaccine efficacy against respiratory disease in pilgrims, we conducted two similar cohort studies on 5...

kawasaki disease (kd) is an acute febrile systemic vasculitis of childhood characterized by elevated levels of inflammatory mediators at the acute stage. high-dose intravenous immunoglobulin (ivig) is well accepted as a conventional therapy for kd. the aim of the present study was to determine the expression level of toll like receptors (tlrs) and their corresponding signaling mediators in pbmc...

Introduction: Beat-to-beat variation in heart rate shows a complex dynamics, and this complexity is changed during systemic inflammatory response syndrome (e.g. sepsis). It is not known whether or not cardiac pacemaker dynamical rhythm is affected by sepsis. The aim of this study was to investigate heart rate dynamics of isolated heart as well as expression of pacemaker channels (HCN) in a r...

Sepsis and sepsis-like illness in neonates and infants are serious emergencies. Recently, human parechovirus type 3 (HPeV-3) has been identified as a further etiologic agent of these conditions. We report two unlinked cases of infant HPeV-3 sepsis-like illness whose sources could be traced back to elder siblings with mild gastroenteritis and respiratory symptoms.
