- PublicationMetadata onlyKounis syndrome, a cause of chest pain to keep in mind, may be associated with E148Q mutation(2012-07-01T00:00:00Z) Saylan, B.; Cevik, A.; Firat, CEM KORAY; FIRAT, CEM KORAYChest pain is among the leading complaints in paediatric emergency. The Kounis syndrome is a rare allergic coronary vasospasm, which can cause angina and myocardial infarction. Even though organic causes are infrequent as a cause of chest pain in children, it is important to know when and how this symptom may become serious. We reported a patient who had been admitted with chest pain to the emergency department, hospitalised for coronary vasospasm and diagnosed to have Kounis syndrome and heterozygous E148Q mutation. The finding could be a coincidental finding, but considering of the heterogeneity and phenotypic differences in FMF, the relationship between E148Q mutation and Kounis syndrome should be explored further.

- PublicationMetadata onlyBeneficial effects of vitamin B12 treatment in pediatric patients diagnosed with vitamin B12 deficiency regarding total-native thiol, oxidative stress, and mononuclear leukocyte DNA damage(2023-01-01) FIRAT C. K.; Ozkan B. N.; Guler E. M.; FIRAT, CEM KORAY© 2023 Informa UK Limited, trading as Taylor & Francis Group.Vitamin B12 is involved in biochemical metabolic pathways. B12 deficiency is common in childhood when the need for the vitamin increases and growth and development occur. Various hematological, neurological, psychiatric, and gastrointestinal disorders are observed in its deficiency. In addition, B12 deficiency is associated with oxidative stress and DNA damage. Therefore, the aim of our study is to evaluate oxidative stress, thiol/disulfide homeostasis, and DNA damage pre and post-treatment in children diagnosed with B12 deficiency. A total of 40 children with B12 deficiency were included in the study after the consent form was approved. Blood was drawn from children pre and posttreatment. Hemoglobin (HGB), hematocrit (HCT), and red blood cells (RBC) were measured by autoanalyzer; total antioxidant status (TAS), total oxidant status (TOS), total thiol (TT), and native thiol (NT) were measured by the photometric method, and DNA damage was analyzed by the comet assay method. Oxidative stress index (OSI) and disulfide (DIS) values were calculated. As a result of the experiments, HGB, HCT, and RBC increased with treatment. While TAS, TT, and NT as antioxidant parameters increased; TOS, OSI, and DIS decreased with treatment compared to pretreatment. DNA damage was also found to decrease with treatment. Additionally, these data were statistically significant (p < 0.001). It was found that oxidative stress and DNA damage decreased with oral B12 treatment in children with B12 deficiency, and clinical parameters were also improved.
