Abstract
Glucose-6-phosphate dehydrogenase (G6PD) enzyme deficiency is common in the community. The most important clinical manifestation of G6PD deficiency is acute hemolytic anemia due to oxidative stressors. Diabetes Mellitus (DM) can precipitate hemolysis in patients with G6PD deficiency. Here, we described a 15-year-old male with newly diagnosed type 1 DM (T1DM) and unknown G6PD deficiency who suffered from hemolytic anemia during normalization of blood glucose. On admission, the patient did not have ketoacidosis. After the patient's blood sugars were regulated with insulin therapy, he presented five days later with hemolytic anemia. The cause of hemolytic anemia was G6PD deficiency. The patient had no previous episodes of hemolysis and had no relevant family history. Hypoglycemia did not occur during blood glucose regulation. The return of blood sugar to normal after a long period of hyperglycemia was thought to be the possible cause of hemolysis. In conclusion, G6PD deficiency should be considered when there is an episode of hemolysis in newly diagnosed children and adolescents with T1DM, especially in the absence of ketoacidosis and hypoglycemia.

Abstract
The majority of the anemias during childhood are hypochromic and microcytic. The aim of the present study was to determine the status of α-thalassemia mutations and its association with other etiologies, such as iron deficiency anemia (IDA) and β-thalassemia trait, that are frequently seen hypochromic microcytic anemias in children. Children with hypochromic microcytic anemias were included in the study. Serum iron (SI), total iron-binding capacity (TIBC), ferritin levels, and hemoglobin electrophoresis with high-performance liquid chromatography (HPLC) method were analyzed. Reverse hybridization of biotinylated polymerase chain reaction (PCR) product method was used for detection of α-globin gene mutations. Of the 46 patients involved in the study, 54.3% (n = 25) were boys, and 45.7% (n = 21) were girls. Iron deficiency anemia and β-thalassemia trait were diagnosed in 67.4% (n = 31) and 19.5% (n = 9), respectively. In 17.4% there were α-thalassemia mutations (in 10.9% 3.7 single-gene heterozygote mutation, in 4.3% 20.5-kb double-gene deletion mutation, and in 2.2% α-2 poly-A-1 heterozygote mutation was detected). In 2 patients (4.3%) no etiology was determined. In 2 patients (4.3%) association between iron deficiency anemia and α-thalassemia, in 1 patient (2.2%) association between β and α-thalassemia was detected. In conclusion, α-thalassemia carrier status and its association with other etiologies are frequently seen in Manisa. So, α-thalassemia should be considered in the differential diagnosis of hypochromic microcytic anemias, especially in cases without iron deficiency (ID) and β-thalassemia carrier state.

Abstract
Iron deficiency anemia (IDA) is frequent in childhood. Inadequate nutrition and gastrointestinal malabsorption are the frequent causes of IDA in children. But reduced iron absorption and insidious blood loss from the gastrointestinal tract has been identified as the most frequent causes of IDA in older children and adolescents. Therefore the authors evaluated the frequency and etiologies of the upper gastrointestinal system pathologies causing IDA in older pediatric population. Patients with known hematological or chronic diseases, heavy menstrual flow, and obvious blood loss were excluded from the study. Forty-four children between the ages of 9.5 and 17.5 years and diagnosed with IDA were enrolled. They underwent upper gastrointestinal endoscopy and biopsy from esophagus, stomach, and duodenum. Mean age and hemoglobin (Hb) levels of study group (32 boys, and 12 girls) were 14.6 ± 2.0 years and 7.9 ± 1.8 g/dL, respectively. Only 1 patient had a positive serology testing with anti-tissue transglutaminase and small bowel biopsy correlating with celiac disease. Endoscopy revealed abnormal findings in 25 (56.8%) patients (21 endoscopic antral gastritis, 2 active duodenal ulcers, and 2 duodenal polyps). Helicobacter pylori (HP) infection was identified by using antral histopathological evaluation in 19 of 44 children (43.2%). In 2 of duodenal samples, one patient had celiac disease, and the other one was diagnosed as giardiasis. In conclusion, there are different etiologies resulting in IDA in older children and adolescents. When older children and adolescents are found to have iron deficiency, HP infection and other gastrointestinal pathologies should be ruled out before iron deficiency treatment.

Abstract
Determination of S-allele combinations of sweet cherry genotypes and cultivars has importance for both growers and breeders. We determined S-allele combinations of 40 local Turkish sweet cherry genotypes using a PCR-based method. Ten different S-alleles were detected. Although the most common S-allele was S3, as also found in Western genotypes and cultivars, there were some differences in the frequencies of some S-alleles between Turkish and Western sweet cherry genotypes. According to their S-allele compositions, 30 local Turkish sweet cherry genotypes were assigned to 10 previously identified incompatibility groups. For the remaining genotypes, whose S-allele combinations did not fit to any previous incompatibility groups, three more incompatibility groups, XLII, XLIII and XLIV, were proposed. Results obtained from this study will help both sweet cherry growers and breeders to better manage these local Turkish sweet cherry genotypes in their orchards.

Abstract
The southern Marmara region in Turkey was surveyed to determine the olive cultivars that are used for olive production. Genetic diversity analysis using simple sequence repeat (SSR) markers indicated that the cultivar Gemlik is the major olive cultivar grown in this region, while other olive cultivars are grown only for use as pollinators of Gemlik or for growers' own exotic consumption. Although the quality of Gemlik is widely accepted in Turkey, its tendency toward alternate bearing is a major drawback. Twenty-four genotypes were selected within the cultivar Gemlik because of their tolerance to alternate bearing. These selected genotypes have the same SSR alleles as Gemlik, making them good candidates for developing a Gemlik olive with reduced alternate bearing. About 8% of samples did not share the same SSR alleles with Gemlik, though these genotypes were identified as Gemlik by the growers. Some other standard cultivars that are grown in other regions of Turkey were mistakenly called Gemlik in this region, probably due to the popularity of this cultivar in the southern Marmara region. In conclusion, as indicated by SSR analysis, Gemlik has become the standard cultivar in this region; future research should be focused on techniques to improve the production and quality of table olives and olive oil from this cultivar.

Abstract
AIM Childhood leukaemia treatment contains multiple chemotherapeutic agents in high doses that can cause severe toxic effects on heart and other vital organs. In this respect patients taking cancer chemotherapy are followed for these adverse effects. Echocardiographic myocardial performance index (MPI) was reported as a new method of combined systolic and diastolic function for both adults and children, calculated as isovolumic relaxation time plus isovolumic contraction time divided by ejection time. In addition, it has been postulated that increased inter-lead differences in QT interval (QT dispersion) may be associated with an increased risk of cardiac death. The aim of this study was to determine the probable immediate and late adverse effects of childhood leukaemia treatment containing moderate dose of anthracyclines on heart by MPI and corrected QT dispersion (QTcD). METHODS MPI and QTcD in 55 children with leukaemia and 38 healthy controls matched for age and sex were evaluated. RESULTS There was no statistically significant difference between MPI values of patients and controls (20.7+/-13.1 (1-59.4) and 16.1+/-13.5 (0.3-77.5), P: 0.1, respectively). Also, there was no significant difference in MPI and QTc values between patients taking active treatment and those who completed the therapy and between the patients given a cumulative dose of anthracycline lower and higher than 250 mg/m2. But QTcD values were found to be higher in patients than controls (0.08+/-0.03 and 0.03+/-0.01, P<0.01, respectively). CONCLUSIONS There was no overt cardiotoxicity in our children with leukaemia treated with protocols of ALL BFM 95 and TRALL 2000 (Modified BFM in Turkey) containing moderate dose of anthracyclines. However, they can cause subclinical cardiotoxicity and further monitoring and evaluation with such sensitive and noninvasive methods over a longer period of time are needed.

Abstract
Thalassaemia major is a severe chronic hemolytic disease, resulted with iron overload mainly due to regular blood transfusions. Iron overload may lead to serious organ toxicity and even fatal complications, if no iron excretion is achieved by a chelating agent. First introduced in 1976 as s.c. treatment for thalassaemia major, desferrioxamine (DFO) has substantially improved the life expectancy in the disease. While DFO can cause local allergic reactions including redness, itching, pain and lumps, on rare occasion anaphylactic reactions can occur. The mechanism of anaphylaxis like reactions is not well understood. In this case report, we presented a 10 years-old girl with thalassaemia major who had to stop DFO therapy after appearing of systemic allergic reactions with hypotension, tachycardia, pruritus and urticaria against this drug. Serum IgE level was normal, specific IgE and skin prick tests were negative. Intradermal test was resulted with positive reaction to DFO. The patient was hospitalized and desensitization protocol was initiated with rapid s.c. infusions per 15 min. The protocol was stopped at the 17th cycle because of local reaction reappeared. After that, DFO was further diluted and was restarted with lower dosage and longer infusion period. Then, DFO dosage was increased and the dilutions and infusion times were decreased gradually. By this desensitization programme, the patient would continue to use DFO chelation safely for 10 months.

Abstract
Invasive pulmonary aspergillosis is a serious infectious complication in immunocompromised especially neutropenic patients. Despite improvements in early diagnosis and effective treatment, invasive pulmonary aspergillosis is still a devastating opportunistic infection. These infections also interfere with the anticancer treatment. We report our experience in the diagnosis and therapeutic management of sinopulmonary aspergillosis in 4 children with hematologic malignancy. All patients except the first were neutropenic when sinopulmonary aspergillosis was diagnosed. Clinical signs included fever, cough, respiratory distress, swallowing difficulty, headache, facial pain-edema and hard palate necrosis. Radiodiagnostic methods showed bilateral multiple nodular infiltrations, soft tissue densities filling all the paranasal sinuses, and bronchiectasis. Diagnosis of aspergillosis was established by bronchoalveolar lavage in one case, tissue biopsy, positive sputum and positive cytology, respectively, in the other 3 cases. One patient was treated with liposomal amphotericin B and other 3 cases were treated with liposomal amphotericin B + itraconozole. Outcome was favorable in all cases except the one who died due to respiratory failure. Early diagnosis, appropriate treatment and primary disease status are important factors on prognosis of Aspergillus infections in children with hematological malignancy.

Abstract
Leukoerythroblastosis is a rarely observed disease characterized by the presence of leukocytosis, erythroid and myeloid blast cells in peripheral blood. To our knowledge, it had not been diagnosed in a premature newborn before the case we report have.A female baby weighing 1164 grams, who was born prematurely at the 29th week of gestation by Cesarean section was referred to our newborn intensive care unit due to prematurity and respiratory distress with no prenatal pathological findings. Physical examination revealed tachypnea and hepatosplenomegaly. Routine laboratory measurements showed significant leukocytosis (85,000/mm3) and anemia (Hb: 9.6 g/dL and Hct: 27.6%). The platelet count was normal. The peripheral blood smear suggested leukoerythroblastosis with the presence of nucleated erythrocytes, monocytosis, and 4% blasts. Bone marrow cytogenetic examination was normal. Parvovirus B19 Ig G and M serology were detected to be positive. The etiological factors observed in leukoerythroblastosis occurring during neonatal and early childhood period are congenital-postnatal viral infections, juvenile myelomonocytic leukemia and osteopetrosis. To our knowledge, no case of leukoerythroblastosis in such an early phase has been reported in the in literature. As a result, premature delivery and leukoerythroblastosis were thought to have developed secondary to intrauterine parvovirus B19 infection. Leukoerythroblastosis is a rarely observed disease characterized by the presence of leukocytosis, erythroid and myeloid blast cells in peripheral blood. It is reported that it can be observed following hematologic malignancies especially juvenile myelomonocytic leukemia, acute infections, hemolytic anemia, osteopetrosis, myelofibrosis, neuroblastoma and taking certain medicines. To our knowledge, it has not been diagnosed in a premature newborn before. Here we the case of a newborn who was referred to our intensive care unit due to being born prematurely at the 29th week of gestation and diagnosed with leukoerythroblastosis.

Abstract
Human telomerase reverse transcriptase (hTERT) is the catalytic component of telomerase enzyme and has been shown to be associated with telomerase activity (TA). Although many studies in adult leukemia have established the importance of TA, very few have been reported in the children. In this study hTERT levels in childhood leukemia was evaluated and compared with the prognostic factors described before. The LightCycler instrument was used (online real-time PCR) for the quantification of hTERT in peripheral blood and bone marrow in 23 cases with acute lymphoblastic leukemia (ALL) and in 8 cases with acute myeloblastic leukemia (AML). Ten cases with normal peripheral blood (PB) and bone marrow (BM) were selected as control group. Cytogenetic analyses were available in 21 patients with leukemia. In all cases with acute leukemia and in control group, peripheral blood (PB) hTERT levels correlated significantly with bone marrow (BM) hTERT levels. Before treatment, patients with ALL had significantly higher hTERT levels than that of AML patients and control cases. Among patients with ALL, higher hTERT levels were observed in patients with pre-B leukemia, followed by B cell and T cell leukemia patients. Initially increased hTERT levels decreased to the nearly normal levels during remission in cases with ALL. No correlation was observed between the initial hTERT levels and the known prognostic factors except cytogenetic findings. Higher hTERT levels were detected in patients having karyotypic abnormalities which indicate poor prognosis. hTERT levels are significantly high in childhood ALL with the highest level of pre-B cell leukemia before treatment. Those high levels of hTERT decrease to almost normal levels in remission. hTERT levels might be useful in monitoring of leukemia in children.
