Case ReportsPeritoneal hemorrhage due to a ruptured ovarian cyst in ITP.
Immune thrombocytopenic purpura in children rarely causes severe bleeding. The incidence of intracranial hemorrhage is approximately 0.2% to 1.0%, and severe bleeding (defined as persistent epistaxis, melena, menorrhagia, gastrointestinal bleeding, etc, requiring hospitalization or transfusion) occurs in only 5% of patients. ⋯ However, females in this age group are in their early childbearing years and present a unique set of possible hemorrhagic complications not seen in younger patients. We present the case of an 18-year-old female with EBV-associated ITP, who developed a severe intra-abdominal bleed secondary to a hemorrhagic ovarian cyst.

Comparative StudyRole of procalcitonin and CRP in differentiating a stable from a deteriorating clinical course in pediatric febrile neutropenia.
In clinical practice, when neutropenic-fever patients present with no microbiologically and clinically defined infection, the risk of underestimating an occult infection is of major concern, the clinicians have to make a decision on when to modify antibiotic therapy. Hence, a reliable, specific, and sensitive marker, which is regulated independently from the leukocyte count and the underlying disease, is needed for the early diagnosis of infections in cases of neutropenic fever. We have evaluated the diagnostic and follow-up value of procalcitonin (PCT) compared with C-reactive protein (CRP) and erythrocyte sedimentation rate in documenting the infection in neutropenic-fever patients undergoing intensive chemotherapy, as evidenced by the durational change in these parameters in the presence of defined infection. ⋯ In sequential analyses of patients without documented infections, the median of PCT concentrations shows a tendency to fall after the 8th hour of onset of fever, whereas in patients with documented infections PCT concentrations fell after the 48th hour. In conclusion, our study suggests that PCT, when measured periodically, is a more useful diagnostic inflammation parameter in pediatric neutropenic-fever patients than CRP, both in estimating the severity of the infection and, the duration and origin of the fever. Hence, PCT might be helpful when deciding on initial therapy modification.
