e and should increase awareness in terms of hemolysis. Early diagnosis of indirect hyperbilirubinemia is essential, as it can prevent to occur serious neurological sequelas. Elevated levels of NRBCs in infants with blood group incompatibilities could alert clinicians about the severity of jaundice and should increase awareness in terms of hemolysis. This study aimed to assess the relationship between antioxidant enzymes such as glutathione peroxidase (GSH-Px), glutathione reductase (GSH-R), and paraoxonase (PON1) and carotid intima-media thickness (CIMT) and investigate susceptibility to atherosclerosis with decreasing antioxidant capacity in adolescent patients with iron deficiency (ID) and irondeficiency anemia (IDA). Twenty-five patients with IDA (14.9±1.8 years; 14 female and 11 male patients), 25 patients with ID (14.1±2.24 years; 13 female and 12 male patients) and 21 healthy controls (14.04±2.01 years; 11 female and 10 male individuals) were included in the study. Serum PON1, GSH-Px, GSH-R, and CIMT were measured in all cases. After 3-month oral iron therapy for the group with IDA, the same measurements were performed again. CIMT was statistically significantly higher in patients with ID and IDA than in the control group (p<0.05). PON1, GSH-Px, and GSH-R activities decreased and were statistically significantly low in patients with IDA compared to the control group (p<0.05). Serum PON1 activity was statistically significantly lower in patients with ID than in the control group (p<0.05). Post-treatment PON1, GSH-Px, and GSH-R activities in patients with IDA got back to normal and were statistically significantly higher compared to pre-treatment values. Antioxidant capacity decreases in patients with IDA and ID, which causes atherosclerotic changes. Therefore, patients with iron deficiency must be treated without the development of iron-deficiency anemia.

Primary Headaches (H) and Learning Disabilities (LD) are frequent in childhood and can coexist in the same subject, but their correlation is not always clear. Aim of our study is to evaluate these relationship considering also any psychopathologies and their influence on the quality of life by considering an aspect such as school absences. 193 children (8-18y) with H and LD assessed consecutively at the Headache Center of L'Aquila, from 2013 to 2018 are the sample. School problems were evaluated by Italian batteries for LD; psychopathology screening by clinical interview and SAFA test. The sample was divided into 3 Groups [Group 1 patients with H (n = 122), Group 2 patients with LD (n = 37), Group 3 patients with H + LD (n = 34)] in order to compare subjects with H and LD vs subjects having only one disorder. The most prevalent headache diagnosis was Migraine without Aura, but Chronic Tension Headache (CTH) showed a stronger impact on quality of life. LD have a higher prevalence in our sample (9.44%) than in general Italian population (3.2%). In Group 3 was higher prevalence of anxiety disorders (p = 0.050) and 50% of patients with CTH was absent from school due to headache. LD can be related to headache chronicization and to a higher prevalence of psychopathologies and school absences, so an early diagnosis of LD in patients with H is crucial to prevent the worsening of the headache itself and of quality of life.

Pulmonary infections are usually caused by bacterial microorganisms such as Pseudomonas aeruginosa, Staphylococcus aureus, Haemophilus influenzae, and Burkholderia cepacia complex in cystic fibrosis (CF) patients. Unusual bacteria (UB) have been described by new isolation techniques recently in the respiratory samples of CF patients. The aim is to investigate the effects of the presence of UB in the respiratory cultures of CF patients on clinical outcomes, necessity of treatment and prognosis. The UB were identified by MALDI-TOF (matrix-assisted laser desorption/ionization time-of-flight) mass spectrometry technology. Rhizobium radiobacter were detected in 2, Chyrseobacterium species (gleum and indolgenes) in 5, Aeromonas hydrophila in 1, Orchobacterium anthropy in 1,Wautersiella falsenii in 1, Leclercia adecarboxylata in 1, Delftia acidovorans in 1, Cupriavidus Gilardi in 1, R.radiobacter twith Elizabethkingia miricola in 1 and R.radiobacter with C.gleum in 1 patient. Median age of the first UB growth was 3 years. After the first UB growth, the median follow-up time was 15 months. Before the UB growth, 60.0% of the patients had respiratory colonization with methicillin-susceptible S.aureus (MSSA). UB growth were accompanied with MSSA in 66.6% of the patients. Median percentage of FEV1 before and during the UB growth for patients who could perform spirometry, were 80 and 102, respectively. https://www.selleckchem.com/products/ipi-549.html Median body mass index before and during the UB growth were 16 and 16.2, respectively. These UB were not detected during the follow-ups except in one patient. The UB growth did not cause any additional symptoms and decrease in BMI and FEV1 in patients with CF. MSSA may be a facilitating factor for UB growth as majority of the patients had MSSA colonization before and during the UB growth.

Antimicrobials, especially antibiotics, are among the most widely used drugs in the pediatric intensive care unit. Pediatrics patients in intensive care unit are exposed to potential drug-drug interactions (PDDIs) and suffered from their adverse and side effects. The aim of this study is to evaluate the impact of antimicrobial use on PDDIs, as well as to examine the rate and the risk factors PDDIs, furthermore the management of PDDIs. The present retrospective cohort study included 179 patients under 18 years of age who were hospitalized in Pediatric Intensive Care Unit in Turkey. Drug interactions were evaluated using the Lexicomp® drug interaction tool which provides evidence-based drug information. Our study results showed that the frequency of the use of antimicrobial drugs (antibiotic, antifungal, antiviral) was found to be statistically significantly higher (p<0.05) in the group with PDDIs compared to the group without PDDIs. Especially, the use of carbapenem, cephalosporin among the antibiotic groups significantly increased the frequency of PDDIs (p<0.
