Because of the acute and life-threatening course of the hemophagocytic lymphohistiocytosis (HLH) syndrome, International Histiocyte Society guidelines recommend chemoimmune therapy for the treatment of both primary and secondary HLH (sHLH). To manage children with sHLH, instead of HLH-2004 protocol we considered less immunosuppressive/cytotoxic approach. We assessed 12 children who fulfilled the diagnostic criteria for sHLH between January 2009 and March 2015. Multivariate Cox regression analysis showed that ferritin levels (hazard ratio=1.02, P=0.006), pediatric logistic organ dysfunction scores (hazard ratio=1.01, P=0.001) were the predictors of the survival. The hospital survival was 83% for patients with sHLH who were treated with less immunosuppressive therapy. In conclusion initiation of HLH-specific therapy for the patients with hyperferritinemia-associated sHLH should be delayed while awaiting resolution of systemic inflammation with less immunosuppressive therapy.

Background:So far, many studies have shown that Human Bocavirus ( HBoV) is the main pathogen of the respiratory tract. Until now, there is no study that proves the association between HBoV and hepatitis. HBoV viremia/DNAemia has been associated closely with acute primary infection and moderate-to-severe illness but, more detailed clinical data about HBoV dissemination are still unavailable.Case Report:Here we report a 2-years-5-months-old girl suffering from respiratory distress and heptitis followed in our intensive care unit. HBoV was detected in our patients nose and throat swabs concurrent with whole blood sample by positive polymerase chain reactions. After a through investigation no causative agent other than HBoV viremia was found.Conclusion:Human Bocavirus viremia with high viral loads may be associated with hepatitis.

Objectives: More than just a headache, migraine attack is a severe, prolonged head pain preceded and/or followed by a constellation of symptoms. Getting a proper diagnosis will be the most challenging step of migraine care. When cranial autonomic symptoms (CASs), and/or neck pain are observed, children are often exposed to advanced tests for additional diseases. The aim of this study was to investigate the frequency of these symptoms in migraine and to compare the clinical characteristics of patients with and without these symptoms. Frequency of the patients that exposed to the additional investigations was searched. Materials and Methods: In this prospective study between February 2016 and March 2017, 170 pediatric patients who were referred to our tertiary teaching hospital with migraine were enrolled. Results: A total of 170 children, 61 male (35.9%) and 109 female (64.1%) were included in the study. CASs were present in 68 patients (40%), single symptom in 31 (45.6%), and multiple symptoms in 37 (54.4%) patients. Of 68 patients with CAS, 24 (35%) patients were referred to allergists and all were tested for inhaler specific IgE and skin tests. Seventy (32.9%) patients had neck pain/stiffness in which 28 (40%) were exposed to radiation. CAS and neck pain were more frequent in patients with frequent attacks ( P = 0.04 and P = 0.032, respectively). Neck pain was more frequent in patients with CAS ( P = 0.029). Conclusions: It is important for pediatricians and primary care physicians to be aware of the common nature of CASs and neck pain/stiffness in children with migraine to prevent unnecessary procedures. High frequency of migrain attacks was associated with high frequency of CAS and neck pain.

Background and objectives. Most cases of severe scorpion envenomation occur in children and are associated with significant morbidity and mortality. Excessive systemic inflammatory response, which leads to multiple organ involvement, is an emerging challenge during severe envenomation. The aim of this study was to investigate if there was any relationship between initial hematological parameters and severe envenomation in pediatric patients presenting with scorpion envenomation.Method. This study was performed retrospectively, at the pediatric emergency unit and pediatric intensive care unit of the Çukurova University Medical School in Turkey. Two hundred and fifty-seven cases with scorpion envenomation, and a control group consisting of one hundred and fifteen healthy children were included in the study.Results. White blood cell, neutrophil, lymphocyte, platelet, neutrophil/lymphocyte ratio (NLR), platelet/ lymphocyte ratio (PLR) and PDW values of patients were higher than the controls (p<0.05). Mean NLR was 3.8 ± 4.7 in patients. Patients were analyzed with the help of the decision tree model, and it was seen that in patients who had applied to hospital in less than an hour after the scorpion sting, 87.5% of the patients whose NLR value was between the 0.519-1.969 interval (below 2.1 which we found as the cut-off value) did not need to be hospitalized in the intensive care unit, 54.1% of the patients whose NLR value was higher than 1.969 needed to be hospitalized at the intensive care unit. Conclusions.Severe envenomation is associated with mortality and morbidity in children. Our findings showed that NLR seems to be a useful tool in predicting severe envenomation.
