Analysis of pediatric thrombotic patients in Turkey.

This study analyzes the data of thrombotic children who were followed up in different pediatric referral centers of Turkey, to obtain more general data on the diagnosis, risk factors, management, and outcome of thrombosis in Turkish children. A simple two-page questionnaire was distributed among contact people from each center to standardize data collection. Thirteen pediatric referral centers responded to the invitation and the total number of cases was 271.

Benefit of high-dose methylprednisolone in comparison with conventional-dose prednisolone during remission induction therapy in childhood acute lymphoblastic leukemia for long-term follow-up.

Eight-year event-free survival (EFS) was evaluated in 205 patients with acute lymphoblastic leukemia (ALL), to consider the efficacy of high-dose methylprednisolone (HDMP) given during remission induction chemotherapy between 1 and 29 days. The St Jude Total XI Study protocol was used after some minor modifications in this trial. Patients were randomized into two groups.

Two booster dose hepatitis B virus vaccination in patients with leukemia.

The aim of this study was to interpret the antibody response to hepatitis B (HB) vaccination following a two booster dose schedule in 94 acute lymphoblastic leukemia (ALL) patients. All patients were between 1-16 years of age with negative hepatitis B virus (HBV) serology and normal hepatic function. Fifty patients were vaccinated with Engerix B vaccine, and 44 patients were vaccinated with GenHevac B vaccine, with a schedule of 0, 1, 6 and 0, 1, 2, as well as booster doses, in 12 and 6 months respectively.

Asymptomatic hypercalciuria: prevalence and metabolic characteristics.

Hypercalciuria is of continuing interest as a risk factor for kidney stones in children. We screened 592 healthy Turkish children (308 boys, 284 girls, aged 3 month-16 years) for hypercalciuria by measurement of urinary calcium/creatinine (UCa/Cr) ratio in the second-morning urine samples. Hypercalciuria was noted in 17 children (2.

Differentiation of leukemic cells induced by short-course high-dose methylprednisolone in children with different subtypes of acute myeloblastic leukemia.

Differentiation of myeloid leukemic cells to mature granulocytes by high-dose methylprednisolone (HDMP, 20-30 mg/kg/day) with a favorable antileukemic effect has previously been demonstrated in children with acute promyelocytic leukemia and acute myeloblastic leukemia (AML) M4. In the present study, three children with other morphological subtypes of AML (two AML M1, one AML M2) were given methylprednisolone (30 mg/kg/day) orally in a single dose. After a short-course (3 or 7 days) of HDMP treatment alone, a striking decrease in blast cells associated with an increase in maturing and abnormally nucleated polymorphonuclear-like cells some containing Auer rods were detected in all patients in peripheral blood or bone marrow smears.
