Background: Gastroesophageal reflux disease (GERD) and food allergy are frequent disorders of childhood. The purpose of this study was to determine the frequency of food allergy in children with refractory GERD., Methods: A total of 151 children resistant to pharmacologic GERD treatment underwent skin prick test, specific immunoglobulin E, eosinophil count, atopy patch test (APT), and oral food challenge, and were then divided into three groups according to the results of oral milk challenge and allergy work-up: group A1, positive oral milk challenge and positive IgE-mediated allergy test; group A2, positive milk challenge and negative IgE-mediated allergy test; and group B, negative oral milk challenge and negative allergy tests., Results: There were 35, 30 and 86 patients in group A1, group A2 and group B, respectively. A total of 28 of 35 patients in group A1 had cow's milk allergy and the other seven patients had egg allergy. APT positivity was more common in group A2. Endoscopic esophagitis was observed in six group A1 patients and in four group A2 patients. Bloody stools, atopic dermatitis and recurrent wheezing episodes were significantly more common in group A1 than in group A2 and group B (P < 0.001, for both)., Conclusion: Cow's milk allergy was observed frequently in children resistant to pharmacologic GERD treatment. Combined skin prick and specific IgE tests, APT and oral food challenge is essential for avoidance of unnecessary elimination diet., (© 2015 Japan Pediatric Society.)

Background: Although there is abundant literature about the morbidity and mortality rates of status epilepticus (SE), little is known about the risk factors of this medical emergency. The aim of the present study is to assess the risk factors of SE in children., Methods: The authors reviewed the medical records of 83 patients admitted to the Pediatric Neurology Unit of Trakya University Hospital, Edirne, Turkey from January 1994 to December 2001 with the diagnosis of SE. Eighty-three patients were compared with 166 controls who were admitted to the same unit due to non-status epilepticus (non-SE) seizure., Results: The univariate analysis demonstrated that SE episodes were significantly associated with a history of birth asphyxia, neonatal seizure, discontinuation of antiepileptic medication, epilepsy, partial seizure evolving to secondary generalized seizures, myoclonic seizure, generalized abnormalities in the neurological examination, neuromotor retardation, generalized background abnormalities on electroencephalogram (EEG), generalized abnormalities on neuroimaging and polypharmacy than non-SE episodes. Logistic regression was used to test the independence of these parameters as predictors of SE risk. Four parameters emerged as significant independent predictors of SE in children in multiple logistic regression: polypharmacy (Odds ratio (OR) 5.17, P = 0.0004), discontinuation of antiepileptic medication (OR 4.04, P = 0.0095), neuromotor retardation (OR 4.03, P = 0.0016) and generalized background abnormalities on EEG (OR 2.48, P = 0.0419)., Conclusion: Polypharmacy, discontinuation of antiepileptic medication, neuromotor retardation and generalized background abnormalities on EEG are indicators in children of a higher risk of SE.

Background: The conventional therapeutic approach in polycythemic newborn infants is to apply partial exchange transfusion (PET) when hematocrit value exceeds 70% or when the infant develops symptoms with the exception of plethora., Methods: In order to investigate the possibility of using platelet count as a simple criterion implying the PET requirement, we retrospectively reviewed polycythemic newborn infants with respect to the relationship between thrombocytopenia and severity of symptoms, and the association of platelet count and the PET performance. Thrombocytopenia has been defined as a platelet count < 150,000/microL., Results: We studied 18 polycythemic infants with thrombocytopenia (group 1, 35%) and 34 without it (group 2, 65%). Perinatal asphyxia, gestational toxemia and intrauterine growth retardation, which are the three common causative factors leading to polycythemia, were not significantly different in the two groups. No correlation existed between platelet counts and hematocrit values within each group, but there was a very significant difference between the two groups in terms of severity of clinical findings (P < 0001); no difference in terms of moderate findings and moderately significant difference with respect to mild symptoms and asymptomatic situation (P < 0.05). Partial exchange transfusion was performed in all patients in group 1, while only 12 infants in group 2 (32%) received transfusion and the difference was statistically significant (P < 0.05). A significant rise in platelet counts has been achieved only in group 1, while hematocrit values decreased significantly in both groups following PET., Conclusions: This study emphasizes the relationship between thrombocytopenia and the severity of clinical findings and PET performance rate in polycythaemic newborn infants, implying that thrombocytopenia is a possible marker of hyperviscosity, the results of which warrant further investigation.
