Cardiac biomarkers can play an important role in the early detection of subclinical heart failure. Our aims are to 1) obtain values of high sensitive cardiac troponin T (hs-cTnT) in long-term survivors of childhood cancer and 2) investigate the potential role of hs-cTnT in the detection of subclinical late-onset cardiotoxicity. ⋯ Hs-cTnT concentrations are normal in long-term survivors of childhood cancer, even in the subpopulations with elevated NT-pro-BNP and/or a mildly decreased EF, indicating that it is not a sensitive marker for late onset subclinical anthracycline induced cardiotoxicity.

Review Case Reports
Misdiagnosis of two cases of hereditary spherocytosis in a family and review of published reports.
Hereditary spherocytosis is usually diagnosed based on a combination of clinical and family histories, physical examination, and laboratory data. Milder or atypical cases can be difficult to diagnose. ⋯ Mild and moderate hereditary spherocytosis can be easily misdiagnosed. Assessment of total, direct, and indirect serum bilirubin, erythrocyte morphology and red cell characteristics (particularly mean corpuscular volume and mean sphered corpuscular volume) clearly distinguishes hereditary spherocytosis from autoimmune hemolytic anemia, glucose-6-phosphate dehydrogenase deficiency, thalassemia, and autoimmune hepatitis.

Comparative Study
Evaluation of two methods to measure hemoglobin concentration among women with genetic hemoglobin disorders in Cambodia: a method-comparison study.
Genetic hemoglobin (Hb) E variants are common in Cambodia and result in an altered and unstable Hb molecule. We evaluated two methods to measure Hb concentration among individuals with and without Hb variants using a hemoglobinometer (HemoCue) and a hematology analyzer (Sysmex XT-1800i). ⋯ Bias and concordance were similar across groups, suggesting the two methods of Hb measurement were comparable. We caution field staff, researchers and policy makers in the interpretation of data and the impact that bias between methods can have on anemia prevalence rates.

Randomized Controlled Trial
Novel markers predict death and organ failure following hemorrhagic shock.
ADAMTS 13, sP-Selectin and HSP27 have been investigated as potential prognostic markers in patients with hemorrhagic shock. ⋯ Serum concentrations of ADAMTS13, HSP27 and sP-Selectin measured during the admission, appear to be comparable to or better than SBP, BD, SI, HR and StO2 in predicting MODS and death after hemorrhage from trauma. These potential new markers deserve further investigation.

Somatic CALR exon 9 mutations have recently been identified in patients with JAK2/MPL-unmutated myeloproliferative neoplasm, and have become an important clonal marker for the diagnosis of essential thrombocythemia (ET) and primary myelofibrosis. In the present study, we sought to use high-resolution melting analysis (HRMA) as a screening method for the detection of CALR mutations. ⋯ The HRMA developed in our system is a rapid and sensitive technique for the detection of CALR exon 9 mutations.
