    Fifty-one children (median age: 4.5 years; 4 months-16 years) diagnosed with rhabdomyosarcoma were treated in our center between 1980-1999. The primary sites were head and neck in 31.4%, the genito-urinary system in 21.6%, and extremities in 9.8% of the patients. The histopathologic subtypes were embryonal in 80.4%, alveolar in 9.8%, and undifferentiated in 9.8%. The majority of the patients were considered group III (47%) and group IV (25.5%) according the criteria of the Intergroup Rhabdomyosarcoma Study (IRS). Primary total tumour resection was performed in only 27.5% of the patients. The patients were treated with assigned regimens of IRS II and IRS III protocols. Radiotherapy was applied to 92.1% of the patients. Thirty-four patients (66.7%) were lost to follow up, and of the remaining 17 patients, 7 patients (41.2%) died, relapse occurred in 9 patients (52.9%) and 10 patients (58.8%) are alive. The percentage of cases lost to follow up during the first 10 years and the following 9 years of the study were 77.4% and 50%, respectively. In compliance with cancer treatment remains a major problem in developing countries.</p

    Pitfalls in the diagnosis of immune thrombocytopenic purpura in children: 4 case reports

    Acute idiopathic thrombocytopenic purpura is the most common cause of thrombocytopenia in childhood, and diagnosis of idiopathic thrombocytopenic purpura is made clinically based on the exclusion of other causes of thrombocytopenia. Patients with diverse causes of thrombocytopenia are sometimes erroneously diagnosed as having idiopathic thrombocytopenic purpura. However, for the prevention of misdiagnoses, careful inspection of peripheral blood smear is of utmost importance. This report presents 4 cases presumed as acute idiopathic thrombocytopenic purpura that were finally identified as pseudothrombocytopenia, inherited macrothrombocytopenia (MHY9 disorders) possibly Epstein syndrome, Bernard-Soulier syndrome, and drug-induced thrombocytopenia. They draw attention to the importance of platelet morphology to exclude inherited macrodirombocytopenia and history to exclude drug-induced thrombocytopenia. Better diagnostic approaches would be possible by the awareness of these relatively rare causes of isolated thrombocytopenia

    Objectives To evaluate the long-term efficacy and safety of deferasirox therapy in a large observational cohort of children with transfusion-dependent thalassemia (TDT) and sickle cell anemia (SCA) in Turkey. Methods This was a multicenter, prospective cohort study including TDT and SCA patients aged 2-18 years with iron overload (>= 100 mL/kg of pRBC or a serum ferritin [SF] level >1000 mu g/L) receiving deferasirox. Patients were followed for up to 3 years according to standard practice. Results A total of 439 patients were evaluated (415 [94.5%] TDT, 143 [32.6%] between 2 and 6 years). Serum ferritin levels consistently and significantly decreased across 3 years of deferasirox therapy from a median of 1775.5 to 1250.5 mu g/L (P = 30 mg/kg/d (n = 120, -579.6 median reduction, P = 30 mg/kg/d) may be required to achieve iron balance
