Leishmaniasis is a reticuloendothelial system disease that mostly observed before the age of 5. Visceral infection causes long-standing fever, weight loss, weakness, pancytopenia, and hepatosplenomegaly. Leishmania infantum is responsible for visceral leishmaniasis (VL) in Turkey.

Fatal Pulmonary Embolism Due to Inherited Thrombophilia Factors in a Child With Wolfram Syndrome.

Wolfram syndrome-1 is a rare and severe autosomal recessive neurodegenerative disease characterized by diabetes mellitus (DM), optic atrophy, diabetes insipidus, and deafness. Poorly controlled type 1 DM increases the risk for thrombosis. However, coexistence of DM and hereditary thrombosis factors is rarely observed.

N-acetylcysteine supplementation reduces oxidative stress for cytosine arabinoside in rat model.

Cytosine arabinoside (ARA-C) is a pyrimidine analog that may cause keratoconjunctivitis when used in high doses. The underlying mechanism may be the increased amounts of reactive oxygen radicals that may damage the DNA synthesis of corneal and conjunctival epithelial cells. Topical corticosteroids are one of the prophylactic treatments for keratoconjunctivitis induced by ARA-C.

Evaluation of Reticulocyte Parameters in Iron Deficiency, Vitamin B12 Deficiency and Mixed Anemia.

Background: Reticulocytes are the youngest erythrocytes released from the bone marrow into the blood and they circulate for 1-2 days before becoming mature erythrocytes. In literature, there were studies about reticulocyte parameters that could help in differentiation of iron deficiency anemia (IDA) from vitamin B12 deficiency anemia. However, in those studies there were no data about differentiation of mixed anemia (vitamin B12 deficiency and IDA).

Impaired Hemorheological Parameters and Increased Carotid Intima-Media Thickness in Children with Subclinical Hypothyroidism.

Background: Subclinical hypothyroidism (SH) is defined as elevated serum thyroid-stimulating hormone (TSH) concentration associated with normal serum-free thyroxine levels. Effects of hypothyroidism on hemorheology had widely attracted the attention of researchers during the last decade.

Objective: The purpose of this study is to determine alterations in hemorheological parameters and carotid intima-media thickness (CIMT) in children with SH.

Pentraxin-3 Levels in Beta Thalassemia Major and Minor Patients and Its Relationship With Antioxidant Capacity and Total Oxidant Stress.

Thalassemia major (TM) results in hemolytic anemia, an increase in intestinal iron absorption, and occurrence of iron loading due to erythrocyte transfusion; the disease is characterized by oxidative damage in major organs. Oxidative stress leads to vascular endothelial damage and forms the basis for serious cardiovascular diseases. Pentraxin-3 (PTX-3) is one of the markers of vascular endothelial damage that increases in response to the oxidative stress, which can be used as an early diagnostic marker for inflammation.

Presacral and intrathoracic extramedullary hematopoiesis: a case report.

Extramedullary hematopoiesis (EMH) refers to the location of hematopoietic elements in locations other than the bone marrow and peripheral blood. It may be seen as a compensatory condition in many hematological conditions including thalassemia, or it may occur as an incidental finding. Intrathoracic EMH commonly develops in the posteroinferior mediastinum.

Cyclosporine level at the second hour in pediatric hematopoietic stem cell transplant patients.

In this retrospective study, cyclosporine levels at the second hour (C2 levels) were measured during oral cyclosporine intake in 28 pediatric hematopoietic stem cell transplant patients, and the relations between cyclosporine dosage and C0, C2 levels, C2/C0 ratio, and cyclosporine-related adverse effects were investigated. Cyclosporine levels at the second hour levels were found to be significantly lower in children younger than 7 years old, suggesting age-related differences in absorption and metabolism of the drug. There were statistically significant correlations of both C0 and C2 levels with blood creatinine values.
