While myocardial infarction is a rare, but known, potential side effect of snakebite envenomation, snake antivenom has thus far not been associated with any cardiovascular adverse events. We report the case of a 71-year-old man who developed an anterolateral MI during administration of Crotalidae immune F(ab')2 (equine) (ANAVIP), given as treatment for Crotalidae envenomation. The patient required cardiac catheterization with stenting of the left anterior descending artery and was discharged two days later on long-term clopidogrel and aspirin.

Objective: Neonatal sepsis and familial hemophagocytic lymphohistiocytosis (fHLH) have similar clinical and laboratory symptoms and the possibility of overlooking fHLH diagnosis is high in newborns with sepsis. History of consanguineous marriage and/or sibling death, hepatomegaly/splenomegaly, and hyperferritinemia (>500 ng/mL) are likely to support fHLH in newborns with sepsis. Therefore, in newborns with sepsis in whom at least 2 of these 3 criteria were detected, genetic variants was investigated for the definitive diagnosed of fHLH.

The improved survival rates of childhood cancers raise the long-term risk of second primary malignancy (SPM) in childhood and adolescent cancer survivors. The intensity of the treatment protocol used, the use of some groups of chemotherapeutics, and radiotherapy were found to be risk factors for the development of second primary malignancies (SPMs). Forty-one patients who developed acute myelocytic leukemia or any solid organ cancer within 25 years of follow-up, after completion of pediatric acute lymphoblastic leukemia (ALL) treatment, were included in the study.

Ag-containing hydroxyapatite (HA) can reduce risks associated with bacterial infections which may eventually require additional surgical operations to retrieve a failed implant. The biological properties of HA in such applications are strongly affected by its composition in terms of dopants as well as Ca/P stoichiometry, which can be easily controlled by altering processing parameters, such as precursor concentrations. The objective of this in vitro study was to understand the effect of variations in HA precursor solutions on antibacterial properties against   and for promoting osteoblast (bone-forming cell) adhesion on Ag incorporated HA (AgHA) which has not yet been investigated.
