The diagnostic value of interleukin-6 and interleukin-8 for early prediction of bacteremia and sepsis in children with febrile neutropenia and cancer.
Early diagnosis of sepsis in children with febrile neutropenia and cancer still remains a challenge for modern medicine because of lack of specific laboratory markers and clinical signs especially at the beginning of the infection. The objective of this study was to evaluate the ability of interleukin-6 and interleukin-8 to predict bacteremia and sepsis during the first 2 days in oncohematologic patients with febrile neutropenia. ⋯ These interleukins could be used as a screening tool for the rejection of sepsis or bacteremia on the first day of fever in neutropenic children with cancer.

Case ReportsFulminant and fatal course of acute lymphoblastic leukemia due to lactic acidosis and suspected abdominal compartment syndrome.
Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy and its prognosis has considerably improved over the past 2 decades due to new therapeutic approaches. In some cases, however, it can develop very rapidly and cause possibly fatal complications. We report on the case of an 11-year-old boy with ALL, who rapidly developed severe lactic acidosis and abdominal compartment syndrome. ⋯ Autopsy revealed systemic leukemic infiltrations. We suppose that the mass of tumor cells induced a cascade of metabolic and endocrine reactions, which not only triggered the rapid progression of the disease but were also accountable for the lack of response to treatment. The pathophysiology of abdominal compartment syndrome as a rare and in our case ultimately fatal complication of ALL is described.

Pandemic H1N1 influenza infection in children with acute leukemia: a single-center experience.
In English literature, there are only 2 specific series of pandemic H1N1 influenza infection in children with leukemia. To increase knowledge about pandemic influenza in children with leukemia and better understand the risk factors for severe disease, we have presented the clinical characteristics of 8 children with acute leukemia and pandemic influenza treated at our center. The mean age of the children (4 girls and 4 boys) was 6.7±2.0 years (range, 4 to 10 y). ⋯ She developed acute respiratory distress syndrome within a short time after the symptoms commenced and she died within 4 days. In conclusion, the clinical course of H1N1 infection may be fatal in rare cases of leukemic children receiving chemotherapy. Thus, vaccination is advisable for all leukemic children, especially for those under maintenance chemotherapy, as it might be life saving during such pandemics.

Bacteremia is one of the most feared infectious complications of sickle cell disease, and it is associated with a high mortality rate in children. The objective of our study was to investigate the proportion of bacteremia among febrile children with sickle hemoglobinopathies and the clinical factors associated with bacteremia. ⋯ Approximately 1% of children with sickle hemoglobinopathies with fever have bacteremia despite current penicillin prophylaxis and pneumococcal immunization, although most episodes are due to nonpneumococcal pathogens. Prompt evaluation of such febrile children with sickle hemoglobinopathies remains warranted.

Case ReportsGilbert syndrome increasing unconjugated hyperbilirubinemia in a child with hereditary spherocytosis.
Hemolytic anemia usually gives rise to only a modest elevation of serum bilirubin. Unconjugated hyperbilirubinemia of an extreme degree should raise suspicion of additional factors. We describe a 10-year-old child suffering from hereditary spherocytosis, who had unusually high levels of unconjugated serum bilirubin and was diagnosed to have Gilbert syndrome on the basis of genetic analysis.
