Background: The aim of this study is to investigate the diagnostic value of cerebrospinal fluid (CSF) and serum levels of the soluble form of triggering receptor-1 expressed on myeloid cells (sTREM-1) in neonatal meningitis. Methods: Serum sTREM-1 levels were measured in all neonatal sepsis patients at the start of antibiotic therapy and the 48th hour of treatment. At the beginning of antibiotic therapy, CSF samples were collected for sTREM-1 measurements. Control CSF samples were also collected from the patients with meningitis at the 48th hour of treatment. Results: A total of 77 preterm (50) and term (27) patients with neonatal sepsis were included in the study. There was no significant difference between the CSF sTREM-1 levels of patients with and without meningitis. The CSF sTREM-1 levels of preterm infants with meningitis decreased significantly after treatment ( p = 0.038). Although the CSF/serum sTREM-1 ratios tended to increase in babies with meningitis, no significant difference was found between the groups. CSF/serum sTREM-1 ratios (mean ± SD) were 1.42 ± 0.91 and 1.14 ± 0.85 in preterm babies with and without meningitis and 1.15 ± 0.97 and 0.97 ± 0.55 in term babies with and without meningitis, respectively. Conclusions: Serum and CSF sTREM-1 levels increase in patients with neonatal sepsis. CSF s-TREM-1 levels decrease after treatment in preterm infants with meningitis.

(1) Background: This study aimed to determine whether standard-dose vitamin D supplementation could provide adequate levels in exclusively breastfed infants born with different cord 25(OH)D levels and to evaluate related neonatal morbidities. (2) Methods: A prospective cross-sectional study was designed in term infants. Three groups were formed based on cord 25(OH)D levels; Group1 Deficiency:25(OH)D < 12 ng/mL, Group2 Insufficiency:25(OH)D = 12-19 ng/mL, and Group3 Optimum:25(OH)D = 20-100 ng/mL. Cord and 1st month 25(OH)D levels, after receiving standard-dose vitamin D prophylaxis, neonatal outcomes and anthropometric measurements were compared. (3) Results: The study involved 86 infants. Group1 Deficiency had also significantly lower 25(OH)D levels at 1st month compared to the others ( p < 0.001). There was a significant positive correlation between cord and 1st month 25(OH)D levels (r = 0.78, p < 0.001). Despite the fact that the mother's age and clothing style were similar, Group1 Deficiency mothers had higher parity numbers and used less vitamin D during pregnancy ( p = 0.03, p = 0.04). Neonatal outcomes analysis revealed that newborns in Group1 Deficiency experienced more respiratory distress, transient tachypnea, and early-onset sepsis, as well as more and longer hospital stays in the first-month of life ( p < 0.05). (4) Conclusions: Infants with low cord 25(OH)D levels had also lower 25(OH)D values in the 1st month of life and experienced higher rates of neonatal morbidities. Given its numerous biological activities and impact on neonatal morbidities, determining an individualized dose of vitamin D supplementation may be more accurate than using the standard approach.

Objective: Portable X-rays remain one of the most frequently used diagnostic procedures in neonatal intensive care units (NICU). Premature infants are more sensitive to radiation-induced harmful effects. Dangers from diagnostic radiation can occur with stochastic effects. We aimed to determine the radiation exposure in premature infants and staff and determine the scattering during X-ray examinations in the NICU., Study Design: In this prospective study, dosimeters were placed on premature infants who were ≤1,250 g at birth and ≤30 weeks of gestational age who stayed in the NICU for at least 4 weeks. The doses were measured at each X-ray examination during their stay. The measurements of the nurses and the doctors in the NICU were also performed with dosimeters over the 1-month period. Other dosimeters were placed in certain areas outside the incubator and the results were obtained after 1 month., Results: The mean radiation exposure of the 10 premature infants, monitored with dosimeters, was 3.65 ± 2.44 mGy. The mean skin dose of the six staff was 0.087 ± 0.0998 mSV. The mean scattered dose was 67.9 ± 26.5 µGy., Conclusion: Relatively high exposures were observed in 90% of the patients and two staff. The radiation exposure levels of premature infants and staff may need to be monitored continuously., Key Points: · The premature infants are exposed to radiation due to the bedside X-rays.. · The radiation exposure levels of premature infants and staff may need to be monitored continuously.. · Measures and alternative methods to reduce radiation exposure should be encouraged.., Competing Interests: None declared., (Thieme.

Background: Povidone-iodine (10%; PI) and 2% chlorhexidine in 70% isopropyl alcohol (CHG-IA) solutions are among the most widely used disinfectants in the neonatal intensive care units. This study compares the use of these disinfectants and helps decide which is superior to the other for neonatal use., Methods: All term and preterm infants born and hospitalized in Bursa Uludag University Hospital between July 2018-March 2020 were included. The infants were randomized into two disinfectant groups before birth. The application site was cleaned with the assigned disinfectant before intervention. The infants were screened for rates of neonatal sepsis, thyroid-stimulating hormone (TSH) levels, free thyroxine (fT4) levels, skin reactions to the assigned solution, and acute neurological side effects., Results: We enrolled 208 term and preterm infants (PI:104 vs. CHG-IA: 104) in the study. The prematurity rates were identical (PI: 74.0%; CHG-IA: 72.1%; p = 0.755). Neonatal sepsis rates among these groups were not statistically different (PI: 8.7%; CHG-IA: 4.8%; p = 0.406). The median TSH value of the PI group was high (4.05 mIU/L) in comparison with that of the CHG-IA group (3.09 mIU/L; p = 0.016). No cutaneous or neurological side effects were recorded in patients treated with CHG-IA solution., Conclusions: Although these two solutions were equally protective against infections, the CHG-IA solution was a better alternative to PI for neonatal use. Considering that the PI solution may be responsible for impaired thyroid function, the CHG-IA solution is a good alternative because it provides sufficient protection with a safer adverse effect profile., (© 2023 Japan Pediatric Society.)

Neonatal intensive care nurses have faced additional difficulties in adapting to a new work environment with a stressful situation brought about by the pandemic. The aim of this study is to evaluate the experiences of nurses working in neonatal intensive care units during the coronavirus disease-2019 (COVID-19) pandemic. Experiences were determined using phenomenology, a form of qualitative research. The study involved 14 neonatal intensive care nurses. The data were analyzed on the MAXQDA qualitative data analysis software in accordance with Colaizzi's 7-step method. Four themes were identified after the interviews: the experiences related to working conditions, neonatal care, psychosocial effect, and social life. In addition, 17 subthemes were created. The study revealed that neonatal intensive care nurses experienced physical, psychological, and social difficulties during the COVID-19 pandemic. It is thought that these results have become even more important to reduce the workload of nurses and to increase the quality of nursing care, especially in times of crisis such as pandemics., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: Decreased renal blood flow plays a vital role in the etiology of acute kidney injury (AKI). In this study, we aim to investigate the role of renal regional oxygen saturation (rSO 2 ) reductions in predicting AKI in the first 24 h of life., Methods: One hundred premature babies with a gestational age of ≤32 weeks were included. Renal and cerebral rSO 2 s were monitored for 24 h by near-infrared spectroscopy. Infants were followed up for the first 7 days for the diagnosis of AKI., Results: Infants' median gestational age was 29 (23-32) weeks, and their birthweight was 1,192 ± 355 g. It was found that the renal rSO 2 values were lower in the first 24 h of life in patients who developed AKI, and this decrease was statistically significant in the first 6 h of life., Conclusions: The low renal rSO 2 values in the early hours of life in premature babies may have a role in predicting AKI., (© 2020 Japan Pediatric Society.)

Background: Necrotizing enterocolitis (NEC) is an important cause of morbidity and mortality in preterm infants. There is limited data about the role of mesenteric oxygenation status during the first enteral feeding. Therefore, the aim of this study was to determine the mesenteric tissue oxygen saturation values before, during and after the first enteral feeding and to evaluate the effect of these values on the development of NEC in preterm infants., Methods: A total of 105 preterm babies with ≤ 32 gestational weeks were included in this prospective study. The continuous monitoring of the mesenteric tissue oxygenation status was performed before, during and 3 hours after the first feeding by near-infrared spectroscopy (NIRS)., Results: The mean gestational week and birth weight of the study group were 28.8±2.1 weeks, and 1215±387 g, respectively. The first enteral feeding was started at 2.4±1.4 days with breast milk in 85% of infants. A total of 12 infants (11.4%) developed NEC (66% stage II, 34% stage III). The mean mesenteric tissue oxygen saturation levels of the infants that developed NEC were significantly lower both before and one hour after feeding (56.1±3.4 vs. 34±8.8, and 47.4±3.3 vs 37.8±10.9, respectively) compared with infants that did not develop NEC., Conclusions: Lower mesenteric tissue oxygenation values measured before, and one hour after enteral feeding was associated with NEC development. We suggest that lower mesenteric tissue oxygenation during continuous monitoring of first enteral feeding may be used to predict NEC development during follow-up.

Aim: Umbilical venous catheters are frequently used in the neonatal period. The incidence of umbilical venous catheter-related thrombosis is between 1.3% and 43% in ultrasound scans. This study aimed to determine the incidence and risk of portal vein thrombosis in patients who were hospitalized in the neonatal intensive care unit and underwent umbilical venous catheter insertion., Material and Methods: Premature infants (≤32 gestational weeks) who were hospitalized in a Level III neonatal intensive care unit and underwent umbilical vein catheter placement between 2016 and 2018, were included in the study. The demographic data, clinical risk factors for thrombosis, number of catheter days, catheter locations, times of detection of thrombosis using Doppler ultrasonography, treatment methods and durations, thrombosis follow-up and examinations were obtained retrospectively from the electronic patient files., Results: Ninety-six patients whose complete data could be reached were enrolled in the study. The mean gestational age of the patients was found as 29±2 weeks and the mean birth weight was 1353±369 g. Portal vein thrombosis was detected in 13.5% (n=13) of the patients. Five of the cases of portal vein thrombose were complete occlusion and eight were partial occlusion. All patients with complete occlusion and six patients with partial occlusion were treated with low-molecular-weight heparin for a mean duration of 31±13.8 days. Thrombosis disappeared in 7-120 days in all patients. A thrombophilia mutation was detected in six patients with thrombosis, four of whom had the PAI-1 4G / 5G mutation., Conclusion: Portal vein thrombosis which has a significant place among the causes of portal hypertension in childhood, is mostly asymptomatic in the neonatal period and cannot be recognized clinically. It is important to screen and follow up patients with umbilical vein catheters using Doppler ultrasonography in terms of PVT after catheter removal to prevent long-term complications., Competing Interests: Conflict of Interest: The authors have no conflicts of interest to declare., (Copyright: © 2020 Turkish Archives of Pediatrics.)

Background: Coronavirus disease-2019 (COVID-19) pandemic has affected millions of people throughout the world since December 2019. However, there is a limited amount of data about pediatric patients infected with the disease agent, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)., Methods: The epidemiological, laboratory, radiological, and treatment features of the pediatric patients who were positive for SARS-CoV-2 based on the reverse-transcription polymerase chain reaction (RT-PCR) test, were investigated retrospectively., Results: The median age of 81 children included in the study was 9.50 years (0-17.75 years). The most frequent symptoms at the time of admission were fever (58%), cough (52%), and fatigue or myalgia (19%). The abnormal laboratory findings in these cases were decreased lymphocytes (2.5%, n = 2), leucopenia (5%, n = 4), and increased lactate dehydrogenase (17.2%, n = 14), C-reactive protein (16%, n = 13), procalcitonin (3.7%, n = 3), and D-dimer (12.3%, n = 10). Three (4%) patients had consolidation in chest computed tomography, and three (4%) had ground-glass opacities. None of the patients needed intensive care except for the newborns. The median time to turn SARS-CoV-2 negative in the RT-PCR test was 5 (3-10) days. The median length of hospital stay was 5 (4-10) days. The time to turn SARS-CoV-2 negative in the RT-PCR test and the length of hospital stay were significantly longer for those aged five years or younger than others ( P = 0.037, P = 0.01)., Conclusion: Compared to adults, COVID-19 is milder and more distinctive in children. As a result, more conservative approaches might be preferred in children for the diagnostic, clinical, and even therapeutic applications., Competing Interests: The authors have no potential conflicts of interest to disclose., (© 2020 The Korean Academy of Medical Sciences.)

Objective: To investigate the effects of maternal preeclampsia on inflammatory cytokines and neonatal outcomes in premature infants., Methods: The study included preterm infants born at gestational age ≤32 weeks in a tertiary university hospital between January 2016 and January 2017. The study group consisted of infants born from mothers with preeclampsia (Group-1), and the control group consisted of infants born from normotensive mothers (Group-2). Demographic characteristics and clinical outcomes of the infants were recorded. IL-6, IL-8, IL-10, and TNF-α cytokine levels were measured from umbilical cord blood samples., Results: A total of 108 infants were included in the study, of which 34 were in the Group-1 and 74 in the Group-2. Gestational ages (29 vs 30 weeks) of the infants in both groups were similar. There was no significant difference between the cytokine levels of infants with and without preeclampsia. The rate of small for gestational age, retinopathy of prematurity, intraventricular hemorrhage, necrotizing enterocolitis, neutropenia, and thrombocytopenia were significantly higher at the infants with preeclampsia., Conclusion: Maternal preeclampsia leads to an increase at the neonatal morbidities in premature infants without causing a significant alteration at the cytokine levels in cord blood., Competing Interests: Conflict of Interest: The authors declared no conflict of interest., (Copyright: © Pakistan Journal of Medical Sciences.)

Background: Parenteral nutrition (PN) has been widely used in preterm infants. The lipid solutions used for PN, however, are associated with oxidative stress and morbidity. The aim of this study was to compare the effectiveness of a new-generation lipid emulsion (SMOFLipid) and olive-oil based lipid emulsion for prevention of PN-associated oxidative damage., Methods: Preterm infants < 32 weeks of gestational age were included in this prospective randomized study. All infants were randomized to SMOFlipid or olive-oil based lipid emulsion (ClinOleic). Lipid peroxidation products were evaluated in all infants. In addition, total antioxidant capacity (TAC), and both pro- and anti-inflammatory cytokines were studied at days 0, 7 and 14., Results: A total of 89 infants (SMOFlipid, n = 42; ClinOleic, n = 47) were enrolled. TAC was higher in the SMOFlipid group compared with the ClinOleic group at all time points, and the difference on day 7 was statistically significant. Although the anti-inflammatory cytokine interleukin-10 was higher in the SMOFlipid group, this difference was not significant. Bronchopulmonary dysplasia (BPD) was lower in the SMOFlipid group (14.1%) than in the ClinOleic group (31.2%), but this finding was non-significant p > 0.05. The rate of severe BPD was significantly lower in the SMOFlipid group., Conclusion: To our best of knowledge, this is the first study to suggest that SMOFlipid might decrease oxidative damage and oxidative-stress-associated morbidity compared with olive oil-based emulsion in preterm infants., (© 2019 Japan Pediatric Society.)

Invasive candidiasis is a common and serious infection in premature newborns. Preventing and treating fungal infections is very important to improve the prognosis of premature infants. Fluconazole and amphotericin B are used as the first choice in the treatment of invasive fungal infections of the newborns. In some cases, fluconazole and amphotericin B cannot be used due to nephrotoxicity, hepatotoxicity or resistant strains. Micafungin, which is among recently developed echinocandins, is the drug of choice in these cases. The use of micafungin in newborns is new and there is a limited experience about the effect of high dose usage in the central nervous system. The aim of this study was to evaluate the electronic files of patients who used micafungin for the treatment of culture-proven or possible invasive fungal infection during their hospital stay in the neonatal intensive care unit during a 24-month period (2016-2017) in the third-level intensive care unit. A total of 15 patients (10 premature and 5 term babies) were included in the study. The mean birth weight of the patients was 1732 ± 999 g and the mean gestational age was 32.2 ± 5.8 weeks. All patients had long-term intensive care and increased risk of invasive candidiasis infection. Central venous catheterization and multiple antibiotics usage were the most common risk factors in these patients. The other risk factors included intubation, total parenteral nutritional use and surgical procedure application. Candida species were isolated from the cultures of four patients. Candida species isolated from patients were Candida albicans, Candida glabrata, Candida catenulata, Candida parapsilosis. The mean time for onset of micafungin was 29.9 ± 16.6 days. Mean duration of micafungin therapy was 22.4 ± 11.2 days. Eight patients received amphotericin B, three patients received fluconazole therapy and four patients did not receive any antifungal therapy before the onset of micafungin. None of these patients had an abnormal kidney or liver function tests due to micafungin use. As a conclusion, high dose (10 mg/kg/day) micafungin is a safe and effective treatment choice both in the treatment of neonatal culture proven or probable invasive candida infections that were caused by refractory Candida strains, and in the case of nephrotoxicity and hepatotoxicity.

Objective: To assess the short- and long-term effects of the adjustable fortification (ADJ) regimen on growth parameters in premature infants and to evaluate the amount of protein supplements given to reach the targeted blood urea nitrogen (BUN) levels., Methods: In this retrospective study, preterm babies who were born at ≤32 weeks gestational age and fed with human milk, were evaluated in two groups. Infants in Group-I were fed only standard fortification (STD). Infants in Group-II were fed the ADJ regimen. The study was conducted between 2011 and 2016., Results: There were 123 infants in the STD group and 119 in the ADJ group. The mean gestational age of the patients in Group-I was 29.7±1.8 weeks, and mean birth weight was 1266.1±347.1 g. The mean gestational age of the patients in Group-II was 29.5±1.9 weeks, and the mean birth weight was 1217.5±345.5 g. The daily increase in weight and weekly increase in HC were significantly higher in the ADJ group infants. Weight and HC of infants in the ADJ group were significantly higher at 40 weeks. At one year corrected age, weight, length, and HC measurements of both groups were similar. In Group-II, 63% of patients required additional protein supplementation up to 1.6 g/day to achieve the target BUN levels., Conclusion: A higher protein intake through the ADJ regimen improves the physical growth rate of premature infants in the NICU and after discharge. However, sometimes, the targeted growth and BUN values cannot be achieved despite the administration of protein at the recommended increased doses. Increasing protein supplementation up to 1.6 g/day is safe, feasible, and beneficial for these infants., Competing Interests: Conflict of Interest: The authors declared no conflict of interest.

Aşut E, Köksal N, Dorum BA, Özkan H. Aluminum exposure in premature babies related to total parenteral nutrition and treatments. Turk J Pediatr 2018; 60: 385-391. This study aimed to measure aluminum contamination of parenteral nutrition (PN) solutions and aluminum contents of parenteral products given to newborn infants for nutrition or treatment. In this study, the aluminum content of the first products used to prepare PN solutions for premature neonates, of the final parenteral products prepared therefrom, and of the parenteral drugs frequently used in newborn units was measured using the inductively coupled plasma mass spectrometry. The aluminum contamination of all parenteral nutritional products evaluated, except for one, was detected to be over the recommended doses. Of all the first products analyzed within the scope of the study, trace-element preparation, preparation containing fat-soluble vitamins, 20% dextrose solution, calcium gluconate ampoule and sodium phosphate ampoule indicated high aluminum contamination. The total aluminum content of the prepared final products was identified to be at least 40% higher than the total aluminum content of the ingredients added to the compound. Accordingly, the minimum amount of aluminum content was measured as 233 μg/kg/day in nutrition solutions prepared for a baby weighing 1,000 g. Contamination was detected in 9 of the 18 drugs evaluated. This study indicated that the rate of aluminum exposure of the premature babies receiving parental nutrition is still much higher than the safe doses recommended as 5 µg/kg/day by the FDA. Products with lower aluminum content should be preferred in the care of premature infants.

Aim: To determine the role of serum insulin-like growth factor-1 levels in the development of retinopathy of prematurity, which is a major cause of childhood blindness worldwide., Material and Methods: We prospectively studied newborn infants born at a postmenstrual age of <32 weeks and birth weights <1 500 gr, between January 1 st , 2015, and December 31 st , 2015. A total of 40 infants were enrolled in the study. The retinal examination time was determined in accordance with the American Academy of Pediatrics recommendations for retinopathy of prematurity screening and follow-up. Retinopathy of prematurity was classified according to the international classification of retinopathy of prematurity. Serum Insulin like growth factor 1 levels were measured serially in blood samples on the 1 st , 3 rd , 7 th , 21 st , and 28 th day., Results: Among the 40 infants, 11 (27.5%) constituted the retinopathy of prematurity group and 29 comprised the non-retinopathy of prematurity group. In the retinopathy of prematurity group, the mean gestational age and birth weight was significantly lower. The demographic features of the study cohort were similar. The duration of mechanical ventilation was significantly greater in the retinopathy of prematurity group compared with the non-retinopathy of prematurity group (p=0.036). In terms of neonatal morbidities such as respiratory distress syndrome, intraventricular hemorrhage, bronchopulmonary dysplasia, patent ductus arteriosus, and necrotizing enterocolitis, no differences were detected between the groups. The mean serum insulin-like growth factor-1 levels in retinopathy of prematurity group were significantly lower than those in the non-retinopathy of prematurity group at each time point (1 st , 3 rd , 7 th , 21 st , and 28 th day of postnatal life) (p=0.001)., Conclusions: This study demonstrated the low serum insulin-like growth factor-1 levels was associated with retinopathy of prematurity development., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors.

Yılmaz C, Köksal N, Özkan H, Dorum BA, Bağcı O. Low serum IGF-1 and increased cytokine levels in tracheal aspirate samples are associated with bronchopulmonary dysplasia. Turk J Pediatr 2017; 59: 122-129. Despite developments in the perinatal and neonatal care, bronchopulmonary dysplasia (BPD) is still the most frequently seen long-term complication in preterm infants. The aim of this prospective study is to investigate the association between the development of BPD and serial measurements of IGF-1 levels and their relationship with levels of IGF-1 and cytokine in tracheal aspirate fluids. A total of 40 premature infants, born at a gestational age of ≤ 32 weeks, were enrolled in the study. On postnatal day-1, 3, 7, 21 and 28 serum IGF-1 levels and IGF-1 levels, IL-6, IL-8, IL-10 and TNF-alpha levels in tracheal aspirate fluid samples of intubated cases were examined. Mean gestational age of 40 patients included in the study was 29.41 ± 2.23 weeks, and their mean birth weight was 1,256.85 ± 311.48 g. BPD was detected in 35% of cases. Mean gestational week and birth weight of the cases that developed BPD were 30 ± 3 weeks and 1,150 ± 295 g, respectively. Serum IGF-1 levels on postnatal day-1, 3, 7, 21 and 28 in cases who developed BPD were significantly lower when compared with those without BPD (p < 0.01). Levels of IL-6, IL-8, IL-10, and TNF-alpha in tracheal aspirate samples were significantly higher in cases with BPD compared to those without BPD (p < 0.05). IGF-1 levels in tracheal aspirate fluid samples did not differ significantly based on the presence of BPD (p > 0.05). Severity of BPD was associated with decreased serum IGF-1 levels and increased cytokine levels in tracheal aspirate samples.

Introduction: Paraquat is a commonly used highly toxic herbicide. Despite many studies on detoxification of paraquat, an efficient and safe antidote has not been introduced for toxic cases in human being. The aim of this study was to investigate the effect of ellagic acid (EA) on paraquat-induced kidney hazards in rats., Materials and Methods: Sixty rats were randomly assigned as controls and 5 treatment groups (n = 10 each) receiving EA only, paraquat at doses of 15 mg/kg and 45 mg/kg, and paraquat at the same doses plus EA. Paraquat was intraperitoneally injected and the EA was orally given. Kidney tissues were stained with hematoxylin-eosin for histopathologic investigation., Results: Pathologic scoring showed that paraquat at the higher dose was associated with higher scores than the in the controls, EA group, and the high-dose paraquat group with EA treatment (P < .001 for all comparisons).  It was noted that paraquat caused a serious damage in the kidney and the EA treatment significantly reduced the extent of the damage., Conclusions: This study showed the protective effects of EA against paraquat-induced nephrotoxicity histologically. Ellagic acid provided significant improvement in glomerular and tubular structure.

Paraquat (PQ), which is used extensively as a potent herbicide throughout the world, is highly toxic in humans. We aimed to determine PQ-induced biochemical and histologic changes in the kidneys, and to evaluate the ability of the protective effects of caffeic acid phenethyl ester (CAPE) against PQ-induced injury in rats. Forty-eight rats were divided into eight groups of six: Group 1: Control; Group 2: 10 μmol/kg CAPE; Group 3: 15 mg/kg PQ; Group 4: 30 mg/kg PQ; Group 5: 45 mg/kg PQ; Group 6: 15 mg/kg PQ+CAPE; Group 7: 30 mg/kg PQ+CAPE; Group 8: 45 mg/kg PQ+CAPE. PQ and CAPE were injected intraperitoneally. The levels of the total oxidant status (TOS) and total antioxidant status (TAS) were determined in the supernatants of the excised left kidney. Right kidney tissue of each rat was removed to obtain a histologic score. When PQ-administrated (15, 30, 45) groups compared with other groups, TOS values were found to be significantly higher (p < 0.01). PQ (15, 30, 45) groups had significantly diminished values of TAS than the other groups (p < 0.001). Of histologic score evaluation, only the PQ45 group had a significantly higher value than the sham, and CAPE groups (p < 0.05). Moreover, in CAPE+PQ45 group, the level of histologic score was decreased compared to PQ45 group (p < 0.001). In conclusion, the evaluation of the data suggests that CAPE can be used to prevent the acute effects of PQ nephrotoxicity., (© 2013 Wiley Periodicals, Inc.)

Duodenal perforation in childhood is a rare condition with a high mortality rate if not treated surgically. Primary gastroduodenal perforation is frequently associated with peptic ulcer and exhibits a positive family history. Helicobacter pylorus is the most significant agent. Secondary gastroduodenal perforation may be a finding of specific diseases, such as Crohn disease, or more rarely may be associated with diseases such as cystic fibrosis or sickle cell anemia. A 14-year-old boy presented with abdominal and back pain. The patient was operated on for acute abdomen and diagnosed with duodenal perforation. Helicobacter pylorus was negative. There was no risk factor to account for duodenal perforation other than sickle cell anemia. Surgical intervention was successful and without significant sequelae. Duodenal perforation is a rare entity described in patients with sickle cell anemia. To our knowledge, this is the first report of duodenal perforation in a patient sickle cell anemia.

Objective: To determine the level and distribution of Cystatin C values in full-term and preterm healthy neonates for the purpose of diagnosis and follow-up of renal diseases of the neonates., Methods: Eighty-eight newborn infants, including 55 preterm and 33 term born in the authors' hospital having no urinary tract pathology, symptoms or signs during prenatal and postnatal follow-up, were studied ., Results: There were 25 neonates born between gestational wk of 28 and 32 (Group 1), 30 neonates born between gestational wk of 33-36 (Group 2) and 33 neonates born after gestational wk of 37 (Group 3). Average cystatin C values were determined to be 1.41 mg/l, 1.22 mg/l and 1.21 mg/l for Group 1, Group 2 and Group 3, respectively., Conclusions: Evaluation of cystatin C can be effective for follow-up of renal pathologies, because it is not affected by gender, body weight and muscle mass and has a constant production rate.
