The Relationship Between Serum Lactate Dehydrogenase Enzyme Levels and Myeloid Engraftment in Hematopoietic Stem Cell Transplantation.

Background: The early detection of myeloid engraftment after hematopoietic stem cell transplantation (HSCT) is of clinical importance for clinicians. In this study, we evaluated whether serum lactic dehydrogenase enzyme levels are significant predictors in the early detection of successful myeloid engraftment after HSCT.

Methods: The study included 74 patients, all of whom underwent HSCT between February 2014 and June 2020.

Coffee-Derived Exosome-Like Nanoparticles: Are They the Secret Heroes?

Background: Regular coffee consumption has beneficial and preventative effects on liver and chronic neurodegenerative diseases. However, the studies performed with the ingredients found in coffee beverages have not clarified the responsible mechanisms. Exosomes are small, membrane-coated cargo packages secreted by prokaryote and eukaryote cells.

Generation of Platelet Microparticles after Cryopreservation of Apheresis Platelet Concentrates Contributes to Hemostatic Activity.

Objective: In the last decade, substantial evidence has accumulated about the use of cryopreserved platelet concentrates, especially in trauma. However, little reference has been made in these studies to the morphological and functional changes of platelets. Recently platelets have been shown to be activated by cryopreservation processes and to undergo procoagulant membrane changes resulting in the generation of platelet-derived microparticles (PMPs), platelet degranulation, and release of platelet-derived growth factors (PDGFs).

Malondialdehyde, antioxidant enzymes, and renal tubular functions in children with iron deficiency or iron-deficiency anemia.

We aimed to investigate the effects of iron deficiency (ID) or iron-deficiency anemia (IDA) on oxidative stress and renal tubular functions before and after treatment of children. A total of 30 children with a diagnosis of IDA constituted the IDA group and 32 children with a diagnosis of ID constituted the ID group. Control group consisted 38 age-matched children.

A neonatal thrombosis patient treated successfully with recombinant tissue plasminogen activator.

Unlabelled: Herein we report an asphyctic preterm neonate with respiratory distress and prothrombotic risk factors that responded positively to rtPA treatment following 2 attacks of acute thrombosis.

Conflict Of Interest: None declared.

Effects of smoking during pregnancy on DNA damage and ROS level consequences in maternal and newborns’ blood.

Some of the genotoxic/carcinogenic substances or metabolites in cigarette smoke are capable of passing through the placenta and harming a newborn’s health. Smoking is also known as a factor in the formation of oxidative damage and the main mechanism involved in the carcinogenic process. Predetermining this genotoxic risk can be successfully achieved by measuring certain parameters of oxidative stress.

Treatment of Priapism with Automated Red Cell Exchange and Hyperbaric Oxygen in an 11-year-old Patient with Sickle Cell Disease.

Priapism affects up to 50% of all males with sickle cell disease, and there is no standard treatment. Delayed and unsuccessful treatment leads to corporal fibrosis and impotence. It is therefore necessary to determine the best treatment methods for this complication in order to offer effective interventions to all affected patients.

Minor anomalies in children with hematological malignancies.

Background: Despite the presence of reports on correlation between major congenital defects and cancer, very few studies have investigated the frequency of minor anomalies in childhood malignancy. The aim of this study was to determine the prevalence of minor anomalies in children with hematological malignancy.

Procedure: A total of 62 well-defined minor anomalies were determined in 109 patients.

Mycoplasma pneumoniae infection associated with pancytopenia: a case report.

Immune hemolytic anemia is a rare condition in childhood. Cold agglutinins have been implicated in the etiology of the hemolysis and frequently observed during Mycoplasma pneumoniae infections. We present here a case of cold agglutinin-related hemolytic anemia, thrombocytopenia, and leukopenia secondary to M.

Plasma levels of trace elements have an implication on interferon treatment of children with chronic hepatitis B infection.

This study evaluated the plasma levels of trace elements in children with chronic hepatitis B virus (HBV) infection and assessed whether they can be a factor that affects the response to interferon alpha (IFN-alpha) treatment. The study included 35 cases (ten girls, 25 boys) aged 3-13 years with chronic HBV infection and the control group. Plasma levels of copper (Cu), manganese (Mn), molybdenum (Mo), selenium (Se), and zinc (Zn) were measured before IFN-alpha treatment and biochemical, virological, and histopathologic response to treatment were assessed.

Do zinc and selenium prevent the antioxidant, hepatic and renal system impairment caused by aspirin in rats?

Aspirin is widely used as an antiinflammatory drug especially in children with rheumatic fever arthritis. The diminishing effects of aspirin on antioxidant enzymes and hepato-renal systems at high doses are well-known. It is now evident that the damage at antioxidant system worsens the clinical picture of the disease and prolongs the treatment time.

Development of in situ melanoma after allogeneic bone marrow transplantation in Griscelli syndrome type II.

GS is an uncommon autosomal recessive disorder characterized by pigmentary dilution of the skin and hair and in most patients by abnormal regulation of the immune system. Childhood melanoma is rare in the pediatric population. The best prognosis is achieved with early diagnosis and definitive surgical excision of melanoma.

G-CSF-mobilized haploidentical peripheral blood stem cell transplantation in children with poor prognostic nonmalignant disorders.

Haploidentical hematopoietic stem cell transplantation (HSCT) is currently one of the alternative curative treatment options for some nonmalignant but also for malignant diseases. However, concerns regarding its safety cause delays in time and a successful outcome. Between 2000 and 2005, twenty-one children with poor prognostic nonmalignant disorders, 13 boys and 8 girls, with a median age of 12 months, underwent 28 haploidentical peripheral HSCT.

All-trans-retinoic acid-induced myositis in a child with acute promyelocytic leukemia.

Anthracyclin-based regimens and all-transretinoic acid (ATRA, tretinoin) as differentiating agent are commonly utilized for the treatment of acute promylelocytic leukemia (APL). There are many adverse effects that may be seen during the use of ATRA in patients with APL. Of these, ATRA-induced myositis is rarely described in adults and rare in the children with APL.

Serum carnitine levels in children with iron-deficiency anemia with or without pica.

Carnitine is ingested through animal-derived foods as well as synthesized in vivo. It plays an important role in the energy metabolism of many tissues. Iron acts as a co-factor for the synthesis of carnitine.

Stroke associated with pseudoephedrine in a child with rhabdomyosarcoma.

Pseudoephedrine is a nasal vasoconstrictor and is contained in many cough and cold medications. It is generally harmless when used in recommended doses. Hypertensive crisis, psychosis, hemorrhagic stroke, and intracranial hemorrhage have been reported as severe complications.
