RESUMO
Background/aim: Hyperoxia- and inflammation-induced lung injury is an important cause of the development of bronchopulmonary dysplasia (BPD) in premature infants. We aimed to ascertain the beneficial effects of ginger ( Zingiber officinale ) on rat pups exposed to hyperoxia and inflammation. Materials and methods: Thirty-six newborn Wistar rats were randomly divided into 3 groups as the hyperoxia (95% O 2 ) + lipopolysaccharide (LPS) group, the hyperoxia + LPS + ginger-treated group, and the control/no treatment group (21% O 2 ). Pups in the hyperoxia + LPS + ginger group were administered oral ginger at a dose of 1000 mg/kg daily during the study period. Histopathologic, immunochemical (SMA and lamellar body), and biochemical evaluations including total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA), myeloperoxidase (MPO), tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1ß), interleukin-6 (IL-6), and caspase-3 activities were performed. Results: Better weight gain and survival rates were shown in the hyperoxia + LPS + ginger group (P < 0.05). In the histopathologic and immunochemical evaluation, severity of lung damage was significantly reduced in the hyperoxia + LPS + ginger group, as well as decreased apoptosis (ELISA for caspase-3) (P < 0.05). Tissue TAS levels were significantly protected, and TOS, MDA, and MPO levels were significantly lower in the hyperoxia + LPS + ginger group (P < 0.05). Tissue TNF-α, IL-1ß, and IL-6 concentrations were significantly decreased in the ginger-treated group (P < 0.05). Conclusion: Ginger efficiently reduced the lung damage and protected the lungs from severe damage due to hyperoxia and inflammation. Therefore, ginger may be an alternative option for the treatment of BPD.

ETHNOPHARMACOLOGICAL RELEVANCE: Necrotizing enterocolitis (NEC) is the most important gastrointestinal emergency affecting especially preterm infants and causes severe morbidities and mortality. However, there is no cure. Oxidant stress, inflammation, apoptosis, as well as prematurity are believed to responsible in the pathogenesis of the disease. Ginger and its compounds have anti-inflammatory, antimicrobial, anti-oxidant properties and immunomodulatory, cytoprotective/regenerative actions. AIM OF THE STUDY: This study aimed to evaluate the beneficial effects of ginger on the intestinal damage in an experimental rat model of NEC. MATERIALS AND METHODS: Thirty newborn Wistar rats were divided into three groups: NEC, NEC +â¯ginger and control in this experimental study. NEC was induced by injection of intraperitoneal lipopolysaccharide, feeding with enteral formula, hypoxia-hyperoxia and cold stress exposure. The pups in the NEC +â¯ginger group were orally administered ginger at a dose of 1000â¯mg/kg/day. Proximal colon and ileum were excised. Histopathological, immunohistochemical (TUNEL for apoptosis, caspase 3 and 8) and biochemical assays including xanthine oxidase (XO), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malonaldehyde (MDA) and myeloperoxidase (MPO), tumor necrosis factor-α (TNF-α), interleukin1ß (IL-1ß), and interleukin 6 (IL-6) activity were evaluated. RESULTS: Compared with the NEC group, the rat pups in the NEC +â¯ginger group had better clinical disease scores and weight gain (pâ¯<â¯0.05). Macroscopic evaluation, Histopathologic and apoptosis assessment (TUNEL, caspase 3 and 8) releaved that severity of intestinal damage were significantly lower in the NEC +â¯ginger group (pâ¯<â¯0.05). The levels of TNF-α, IL-1ß and IL-6 in the ginger treated group were significantly decreased (Pâ¯<â¯0.05). The GSH-Px and SOD levels of the ginger treated group were significantly preserved in the NEC +â¯ginger group (pâ¯<â¯0.05). The tissue XO, MDA and MPO levels of the NEC +â¯ginger group were significantly lower than those in the NEC group (Pâ¯<â¯0.05). CONCLUSION: Ginger therapy efficiently ameliorated the severity of intestinal damage in NEC and may be a promising treatment option.

Background: Turkey is the leading country among those that accept Syrian refugees. This study aimed to determine the density of Syrian refugees who received inpatient treatment at Ankara Child Health and Diseases Hematology Oncology Training and Research Hospital between January 2016 and August 2017. Methods: Syrian refugees' gender, age, place of birth, duration of hospitalization, admission diagnosis and services required as an inpatient were recorded from the registration system. Admission diagnoses were grouped according to the 'International Statistical Classification of Diseases and Related Health Problems'. Results: A total of 623 Syrian patients were included in this research. The median age of inpatients was 25.1 months; 58% (362/623) were male and 41% (257/623) were born in Turkey. The mean duration of hospitalization was 3 d. The highest number of admissions was observed in January. Pediatric emergency (17.7%) and pediatric surgery (12%) departments were the services with the highest number of admissions in this hospital. The most common admission reasons were found to be respiratory tract diseases, acute gastroenteritis and burns. Conclusions: Syrian refugees received inpatient treatment in services with different diagnoses. Preventive health measures targeting Syrian refugees may provide treatment at an earlier stage and reduce the rate of hospitalization.

OBJECTIVE: ADAMTS-1 is a matrix metalloproteinase which cleaves versican in the cumulus oocyte complex under the effect of luteinizing hormone surge in the periovulatory period. Altered levels may have a role in the pathogenesis of polycystic ovary syndrome (PCOS). We aimed to determine the serum versican and ADAMTS-1 (a disintegrin and metalloproteinase with thrombospondin motif-1) levels in PCOS patients and compare the results with healthy controls. METHODS: Thirty-eight patients with PCOS and forty healthy controls aged between 15 and 22 years were included in the study. They were sampled according to their basal hormone, serum versican, and ADAMTS-1 levels. Serum versican and ADAMTS-1 levels were measured by enzyme-linked immunosorbent assay. A multivariate logistic regression model was used to identify the independent risk factors of PCOS. RESULTS: Serum versican levels were significantly decreased in the PCOS group when compared with the controls. The best versican cut-off value for PCOS was calculated to be 33.65 with 76.74% sensitivity and 52.94% specificity. Serum versican levels, homeostasis model assessment of insulin resistance index, a Ferriman-Gallwey score higher than 8, and oligomenorrhea were the strongest predictors of PCOS. Serum versican levels were significantly decreased in PCOS patients. Besides, serum ADAMTS-1 and versican levels were significantly and positively correlated with each other. CONCLUSION: Serum versican levels were significantly decreased in patients with PCOS. This suggests a possible role of versican in ovulatory dysfunction and in the pathogenesis of PCOS.

AIM: Intrahepatic cholestasis of pregnancy (ICP), the most common liver disease in pregnancy, is characterized by elevated serum total bile acid and/or transaminase concentration, and pruritus. Interleukin-6 (IL-6) is a key regulator of the immune response, hematopoiesis and inflammation. We examined both IL-6 and the frequently used inflammatory marker high-sensitivity C-reactive protein (hs-CRP) at baseline in the same study population as for the primary endpoint, in order to provide a new perspective on the pathogenesis of ICP. METHODS: In this controlled cross-sectional study 65 consecutive pregnant women with ICP (34 with mild and 31 with severe disease) and 40 healthy women with uncomplicated pregnancies (control group) were examined. IL-6 and hs-CRP were compared between the groups. RESULTS: While serum IL-6 was significantly higher in the mild ICP (P = 0.01) and severe ICP (P = 0.001) groups than in the control group, hs-CRP was similar between the groups. CONCLUSION: Interleukin-6 may have an essential role, apart from CRP, in the pathogenesis of ICP and, also, is a more sensitive marker of inflammation.

OBJECTIVES: Our aim was to determine serum perforin and granzyme-B levels in adolescent PCOS patients, and to investigate whether they are associated with some of the insulin sensitivity, obesity and cardiovascular (CV) risk markers and metabolic syndrome. STUDY DESIGN: A case-control study was carried out including a total of 172 adolescents (83 PCOS patients and 89 age-matched healthy controls). Participants were recruited consecutively. Homeostasis model assessment (HOMA-IR), lipid parameters, and anthropometric measurements were determined. Serum perforin and granzyme B levels were measured by commercially available ELISA kits. HOMA-IR>3.16 was considered to indicate the presence of insulin resistance. Logistic regression analysis was applied for the predictive value of granzyme-B for increased CV risk in PCOS patients. RESULTS: As body mass index (BMI) of the PCOS patients was significantly higher than the controls (median 24.6kg/m(2) and 21.4kg/m(2), respectively, p<0.001) all parameters were evaluated after adjustment for BMI. Adolescents with PCOS had significantly higher levels of fasting glucose, insulin, HOMA-IR and granzyme-B when compared with controls. According to the results of logistic regression analysis, granzyme-B levels were found to be significantly associated with increased HOMA-IR (OR=6.120, 95% CI: 2.352-15.926, p<0.001) in adolescent PCOS patients. Additionally, elevated levels of serum granzyme-B were predictive for increased CV risk in PCOS patients (OR=0.237, 95% CI: 0.091-0.616, p=0.003). CONCLUSIONS: Increased levels of serum granzyme-B are independently associated with insulin resistance and also with increased CV risk in adolescent polycystic ovary syndrome patients.

Vitamin D is an essential precursor to the steroid hormone calcitriol which mainly regulates calcium homeostasis. Moreover anti- proliferative, pro- apoptotic, anti- angiogenic effects of Vitamin D support the ideas of preventive role in various cancer. This study aimed to determine if there is a relationship between HPVDNA infection and cervical intraepithelial neoplasia and Vitamin D deficiency. As a result of the study the difference of 25-OH Vitamin D3 levels between HPVDNA positive group and the control group were statistically significant (p=0,009). According to results of our study, with the proven anti-inflammatory functions of Vitamin D, the deficiency of these molecule and its metabolites can be a possible reason for HPVDNA persistence and related cervical intraepithelial neoplasia.

STUDY OBJECTIVE: We assessed factors that might affect perinatal outcomes in second pregnancies in adolescents. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, MAIN OUTCOME MEASURES: This longitudinal retrospective study was carried out on 66 adolescents who experienced 2 deliveries during their adolescence. Data were collected for the first and second pregnancies. Odds ratios (ORs) and 95% confidence intervals (CIs) for adverse perinatal outcomes in the second pregnancy were calculated using a logistic regression model and SPSS software (version 17.0 for Windows; SPSS Inc, Chicago, IL). A P value < .05 was considered to indicate statistical significance. RESULTS: Body mass index, number of antenatal care visits, weight gain during pregnancy, incidence of anemia, smoking status, gestational week at delivery, cesarean section rate, and birth weight were similar between the first and second pregnancies of these adolescents. Neonatal intensive care unit admission rate, preeclampsia rate, low neonatal birth weight rate, and 5-minute Apgar scores <7 were significantly higher in the first than in the second pregnancy (P < .001). Age of 16 years or younger at the time of first pregnancy (OR = 1.5; 95% CI, 0.9-2.1; P < .01), less than an 18-month interval between births (OR = 1.4; 95% CI, 0.2-1.7; P < .04), presence of gestational complications in the first pregnancy (OR = 1.9; 95% CI, 1.0-3.4; P < .01), and the presence of perinatal complications in the first pregnancy (OR = 1.3; 95% CI, 1.0-1.9; P < .01) were found to be significant indicators for adverse neonatal outcomes in second pregnancies of adolescents. CONCLUSION: We found that the second pregnancies of adolescents were associated with fewer adverse perinatal outcomes than were their first pregnancies. However, some factors regarding the presence of perinatal complications in the first pregnancy, such as maternal age of 16 years or younger at the time of the first pregnancy and interval between first and second pregnancy of less than 18 months, were found to increase the risk of adverse perinatal outcomes for the second births.

OBJECTIVE: Previous studies have reported on a link between carboxyhemoglobin (COHb) levels and the severity of presenting findings. However, studies on pediatric populations evaluating the effect of age on presenting symptoms are severely lacking. The aim of this study was to investigate the presence of any link between age and presenting symptoms in children with carbon monoxide (CO) poisoning. METHODS: This retrospective study was undertaken in Ankara Children's Hematology and Oncology Hospital, a tertiary care center, between January 2007 and March 2010. The medical records of patients aged between 0 and 16 years with a confirmed diagnosis of CO poisoning, defined as the presence of a COHb level of more than 5%, were evaluated. Relevant information such as age, sex, source of CO, coaffected family members, month of presentation, time of presentation and presenting symptoms, duration of oxygen treatment in the emergency department, need for admission to an inpatient ward or intensive care unit, Glasgow Coma Scale scores, and administered treatments during follow-up was recorded for each patient on preprepared forms. For the purpose of comparison, patients were divided into 2 groups based on COHb levels (group 1, 5%-25%; group 2, >25%). Comparisons were also made after dividing patients into 3 age groups: infants (0-3 years), preschool and early-school children (4-8 years), and adolescents (9-16 years). RESULTS: The records of 261 patients were deemed sufficient for inclusion in the final analysis, 149 (57.1%) of which were female, and 112 (42.9%) were male, with a median age of 7.0 years (range, 1 month to 16 years) and a mean COHb level 16.9% (SD, 7.8%). Two hundred eighteen patients (83.5%) had a COHb between 5% and 25% on presentation, whereas the remaining 43 patients (16.5%) had a presenting COHb of greater than 25%. Neurologic symptoms such as headache, syncope, seizures, and confusion were encountered more frequently in the COHb greater than 25% group compared with the group with 5% to 25% COHb levels, with adolescents having more severe symptoms than do younger patients. CONCLUSIONS: In this study, we managed to demonstrate the presence of more severe symptoms in patients with a COHb level of 25% or greater. Further analysis revealed that severe symptoms were more pronounced in adolescents and that the severity of symptoms increased with age.

BACKGROUND: In April 2009 a novel strain of human influenza A, identified as H1N1 virus, rapidly spread worldwide, and in early June 2009 the World Health Organization raised the pandemic alert level to phase 6. Herein we present the largest series of children who were hospitalized due to pandemic H1N1 infection in Turkey. METHODS: We conducted a retrospective multicentre analysis of case records involving children hospitalized with influenza-like illness, in whom 2009 H1N1 influenza was diagnosed by reverse-transcriptase polymerase chain reaction assay, at 17 different tertiary hospitals. RESULTS: A total of 821 children with 2009 pandemic H1N1 were hospitalized. The majority of admitted children (56.9%) were younger than 5 y of age. Three hundred and seventy-six children (45.8%) had 1 or more pre-existing conditions. Respiratory complications including wheezing, pneumonia, pneumothorax, pneumomediastinum, and hypoxemia were seen in 272 (33.2%) children. Ninety of the patients (11.0%) were admitted or transferred to the paediatric intensive care units (PICU) and 52 (6.3%) received mechanical ventilation. Thirty-five children (4.3%) died. The mortality rate did not differ between age groups. Of the patients who died, 25.7% were healthy before the H1N1 virus infection. However, the death rate was significantly higher in patients with malignancy, chronic neurological disease, immunosuppressive therapy, at least 1 pre-existing condition, and respiratory complications. The most common causes of mortality were pneumonia and sepsis. CONCLUSIONS: In Turkey, 2009 H1N1 infection caused high mortality and PICU admission due to severe respiratory illness and complications, especially in children with an underlying condition.
