    Acute Amitriptyline Poisoning in Childhood: Experience of a Single Center
    (İnönü Üniversitesi Tıp Fakültesi Dergisi, 2013) Ozdemir, Ramazan; Bayrakcı, Benan; Tekşam, Ozlem
    Objective: High-dose amitriptyline is a common cause of childhood poisoning. The aim of this study was to evaluate the demographic and clinical characteristics of 126 children who presented with amitriptyline poisoning. Material and Methods: The medical records of children who were admitted to the Pediatric Intensive Care Unit for amitriptyline poisoning between January 1986 and March 2011 were retrospectively evaluated. Results: High-dose amitriptyline is a common cause of childhood poisoning. An increase in the number of cases of amitriptyline poisoning was observed in recent years, with 62.7% of all cases being accidental whereas 37.3% of cases were attempted suicides. The mean age of accidental cases of poisoning was 2.9±1.4 years compared to 14.2±1.9 years for suicidal cases (p<0.01). Patients who accidentally ingested amitriptyline presented to a health care facility in a shorter period than those who took the drug with suicidal intent (respectively 2.4±2 hours vs. 4.2±4.3 hours; p<0.01). In 78.3% of cases, the drug was stored in place easily accessible to children. While 37.3% of patients took the drug at toxic doses, in 47.6% of patients the amount of amitriptyline ingested was below the toxic dose. Seventy-one percent of patients had neurological symptoms on presentation. Gastric lavage was the most commonly utilized treatment modality (78% all of cases). Only one patient who had accidentally consumed the drug at a dose of 15mg/kg died. Conclusion: There is a dire need for reforms in political, industrial and public health policies regarding the packaging and storage of medications which are a common cause of accidental drug poisoning with potentially severe consequences.

    Acute kidney injury and peritoneal dialysis in extremely low birth weight newborns
    (Edizioni Minerva Medica, 2023) Kaya, Huseyin; Gokce, Ismail K.; Turgut, Hatice; Ozdemir, Ramazan; Tabel, Yilmaz
    BACKGROUND: In 12.5-56% of extremely low birth weight (ELBW) infants treated in newborn units, acute kidney injury (AKI) develops. Some of these infants may need renal replacement therapy for several reasons including hyperkalemia, hypovolemia and resistant acidosis. METHODS: All ELBW infants who were followed in our hospital between January 2015 and December 2017 and who lived longer than 48 hours were assessed. Patients were followed for AKI and peritoneal dialysis (PD). RESULTS: AKI developed in 25 of 201 ELBW infants. PD was administered to nine patients. PD was initiated at a median of 11 days (2-22 days) for all patients due to hyperkalemia which did not respond to medical treatment. Three of the nine infants who received PD died while dialysis was ongoing. The remaining six patients completed PD successfully. In these patients, the serum potassium value returned to normal in three days, and dialysis was continued for a median of 93 hours (40-172 hours). Dialysis leakage occurred in two patients, and hyperglycemia developed in two patients. On average, diuresis started at the 25(th) hour (8-40(th) hour). CONCLUSIONS: In the renal failure treatment of ELBW infants, PD is the only option which can be used for many units. It was found that in ELBW infants, who had wider peritoneal surface when compared to their body weight, biochemical values recovered rapidly with PD, and diuresis started a short while later in most patients.

    All-Trans-Retinoic Acid Attenuates Intestinal Injury in a Neonatal Rat Model of Necrotizing Enterocolitis
    (Karger, 2013) Ozdemir, Ramazan; Yurttutan, Sadik; Sari, Fatma Nur; Oncel, Mehmet Yekta; Erdeve, Omer; Unverdi, Hatice Germen; Uysal, Bulent
    Background: Ischemia/reperfusion-induced intestinal injury is mediated by reactive oxygen species and inflammatory mediators. Objectives: This study was designed to evaluate whether all-trans-retinoic acid (ATRA) administration can attenuate intestinal injury and to analyze the antioxidant and anti-inflammatory effects of ATRA in a neonatal rat model of necrotizing enterocolitis (NEC). Methods: Twenty-nine Wistar albino rat pups were randomly divided into 3 groups: group 1 = control, group 2 = NEC and saline, and group 3 = NEC and ATRA treatment. NEC was induced by hyperosmolar enteral formula feeding and exposure to hypoxia after cold stress at +4 degrees C and oxygen. Pups in group 3 were injected intraperitoneally with ATRA (0.5 mg/kg body weight) once a day prior to each NEC procedure, beginning on postnatal day 1 and daily through postnatal day 4. The pups were killed on the 4th day and their intestinal tissues were harvested for biochemical and histopathological analysis. Results: Mucosal injury scores and intestinal malondialdehyde levels in group 2 were found to be significantly higher than other groups (p < 0.05). Intestinal superoxide dismutase and glutathione peroxidase activities in group 3 were significantly higher than group 2 (p = 0.04 and p = 0.04, respectively). Intestinal tissue tumor necrosis factor-alpha levels were significantly reduced with ATRA treatment in group 3 compared to group 2 (p < 0.001). Conclusions: It is likely that oxidative stress and inflammatory mediators contributed to the pathogenesis of NEC and that ATRA had a protective effect on intestinal injury through its anti-inflammatory and antioxidant properties.

    Assessment of myocardial changes in athletes with native T1 mapping and cardiac functional evaluation using 3 T MRI
    (Springer, 2016) Gormeli, Cemile Ayse; Gormeli, Gokay; Yagmur, Julide; Ozdemir, Zeynep Maras; Kahraman, Aysegul Sagar; Colak, Cemil; Ozdemir, Ramazan
    Intensive physical exercise leads to increases in left ventricular muscle mass and wall thickness. Cardiac magnetic resonance imaging allows the assessment of functional and morphological changes in an athlete's heart. In addition, a native T1 mapping technique has been suggested as a non-contrast method to detect myocardial fibrosis. The aim of this study was to show the correlation between athletes' cardiac modifications and myocardial fibrosis with a native T1 mapping technique. A total of 41 healthy non-athletic control subjects and 46 athletes underwent CMR imaging. After the functional and morphological assessments, native T1 mapping was performed in all subjects using 3.0 T magnetic resonance imaging. Most of the CMR findings were significantly higher in athletes who had a parts per thousand yen5 years of sports activity when compared with non-athletic controls and athletes who had < 5 years of sports activity. Significantly higher results were shown in native T1 values in athletes who had < 5 years of sports activity, but there were no significant differences in the left ventricular end-diastolic volume, left ventricular end-diastolic mass, or interventricular septal wall thickness between non-athletic controls and athletes who had < 5 years of sports activity. The native T1 mapping technique has the potential to discriminate myocardial fibrotic changes in athletes when compared to a normal myocardium. The T1 mapping method might be a feasible technique to evaluate athletes because it does not involve contrast, is non-invasive and allows for easy evaluation of myocardial remodeling.

    Beneficial effects of Etanercept on experimental necrotizing enterocolitis
    (Springer, 2014) Yurttutan, Sadik; Ozdemir, Ramazan; Canpolat, Fuat Emre; Oncel, Mehmet Yekta; Unverdi, Hatice Germen; Uysal, Bulent; Erdeve, Omer
    Tissue damage in necrotizing enterocolitis (NEC) of infants occurs as a result of an uncontrolled inflammatory response. The aim of this study was to investigate any potential anti-inflammatory effects that Etanercept may have on the inflammatory response in an experimental NEC model in newborn rats. Newborn pups were randomized into three groups immediately after birth (Control, NEC + Placebo and NEC + Etanercept). Pups in the NEC + Placebo and NEC + Etanercept groups were subjected to an NEC-inducing protocol (hypercarbia, hypothermia and hyperoxia) twice a day for 3 days. Pups in the NEC + Etanercept group were given an intraperitoneal injection of Etanercept. Rats were harvested for biochemical and histopathological examinations. The histopathological injury score of rats in the NEC + Placebo group was significantly higher compared to the NEC + Etanercept and Control groups (p < 0.05 for both comparisons). Tissue levels of tumor necrosis factor-alpha, interleukin-1 beta, and malondialdehyde were higher in the placebo group compared to the Etanercept group. Our results suggest that Etanercept attenuates intestinal tissue damage in NEC by reducing inflammation and blocking the production of free-oxygen radicals, while also reducing tissue levels of tumor necrosis factor-alpha and interleukin-1 beta.

    Colchicine Protects against Hyperoxic Lung Injury in Neonatal Rats
    (Karger, 2012) Ozdemir, Ramazan; Yurttutan, Sadik; Talim, Beril; Uysal, Bulent; Erdeve, Omer; Oguz, Serife Suna; Dilmen, Ugur
    Background: Bronchopulmonary dysplasia (BPD) is characterized by inflammation, fibrosis and mucosal necrosis, which leads to emphysematous coalescence of alveoli. Objective: We tested whether prophylaxis with colchicine, an anti-inflammatory, antioxidant and antifibrotic drug, would decrease the severity of lung injury in an animal model of BPD. Methods: Twenty-five rat pups were divided into three groups: control (n = 8), hyperoxia (n = 7), and hyperoxia + colchicine (n = 10). The hyperoxia groups were exposed to >95% oxygen from day 1 to 10 of life. On day 10, the animals were sacrificed and the lungs were processed for histology and biochemical analysis. Lung morphology was assessed by the mean linear intercept (MLI), a measure of alveolar size. The degree of lung inflammation and antioxidant capacity were assessed by quantifying lung homogenate tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), malondialde-hyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels. Results: Colchicine significantly decreased lung damage as determined by the MLI in the c groups (p < 0.01). The median level of lung MDA was significantly higher in the hyperoxia group compared with the control group (p < 0.05) and the colchicine-treated group (p < 0.05). Lung homogenate SOD and GSH-Px activities in the colchicine-treated group were significantly higher than in the hyperoxia group (p < 0.05). Furthermore, colchicine-treated pups had lower lung homogenate TNF-alpha and IL-1 beta levels compared with the hyperoxia group (p < 0.05). Conclusions: Colchicine has favorable effects on alveolarization as well as inflammation and oxidative stress markers in an animal model of BPD. Copyright (C) 2012 S. Karger AG, Basel

    Comparison of myocardial bridging prevalence using 64-slice versus 256-slice computed tomography scanners: What has changed with recent innovations in CT?
    (Scientific Publishers India, 2016) Gormeli, Cemile Ayse; Yagmur, Julide; Ozdemir, Ramazan; Ozdemir, Zeynep Maras; Kahraman, Aysegul Sagir; Colak, Cemil
    Objective: To compare the incidence and appearance of myocardial bridging (MB) by computed tomography (CT) angiography using 64-slice versus 256-slice CT. Methods: In total, 775 consecutive patients who underwent coronary CT angiography were evaluated using a 64-slice or a 128x2-slice dual-source scanner. Results: The prevalence of MB was 13.9% using 64-slice-CT and 31.5% using 256-slice-CT. The superficial type of MB segments was detected three times more frequently by 256-slice-CT. Conclusions: A higher prevalence of MB and the superficial type of bridging were revealed with the 256-slice-CT scanner. Advances in CT technology may enable detection and potentially prevent the unwanted effects of MB.

    Comparison of Three Different Administration Positions for Intratracheal Beractant in Preterm Newborns with Respiratory Distress Syndrome
    (Elsevier Taiwan, 2016) Karadag, Ahmet; Ozdemir, Ramazan; Degirmencioglu, Halil; Uras, Nurdan; Dilmen, Ugur; Bilgili, Gokmen; Erdeve, Omer
    Background: The aim of this study was to compare the efficacy and adverse effects of various intratracheal beractant administration positions in preterm newborns with respiratory distress syndrome. Methods: This study was performed on preterm newborns with respiratory distress syndrome. The inclusion criteria were being between 26 weeks and 32 weeks of gestational age, having a birth weight between 600 g and 1500 g, having received clinical and radiological confirmation for the diagnosis of respiratory distress syndrome (RDS) within 3 hours of life, having been born in one of the centers where the study was carried out, and having fractions of inspired oxygen (FiO(2)) >= 0.40 to maintain oxygen saturation by pulse oximeter at 88-96%. Beractant was administered in four positions to Group I newborns, in two positions to Group II, and in neutral position to Group III. Results: Groups I and II consisted of 42 preterm infants in each whereas Group III included 41 preterm infants. No significant differences were detected among the groups with regards to maternal and neonatal risk factors. Groups were also similar in terms of the following complications: patent ductus arteriosus (PDA), pneumothorax, intraventricular hemorrhage (IVH), chronic lung disease (CLD), retinopathy of prematurity (ROP), necrotising enterocolitis (NEC), death within the first 3 days of life, death within the first 28 days of life, and rehospitalization within 1 month after discharge. Neither any statistically significant differences among the parameters related with surfactant administration, nor any significant statistical differences among the FiO(2) levels and the saturation levels before and after the first surfactant administration among the groups were determined. Conclusion: In terms of efficacy and side effects, no important difference was observed between the recommended four position beractant application, the two position administration, and the neutral position.

    Coronary collateral circulation: Any effect on P-wave dispersion?
    (Sage Publications Inc, 2008) Aslan, Halil; Turgut, Okan; Yalta, Kenan; Yilmaz, Mehmet B.; Ozdemir, Ramazan; Ermis, Necip; Sezgin, Alpay T.
    Coronary collateral circulation determines the severity of ischemic myocardial damage. Increased P-wave dispersion is an independent predictor for atrial fibrillation. Consistent evidence is little about the relation between coronary collateral circulation and arrhythmia risk. In this article, the effect of coronary collateral circulation on P-wave dispersion was evaluated. Collateral grade and p-wave dispersion were ascertained in 100 patients with >= 85% diameter stenoses in left anterior descending or right coronary arteries. Left ventricular function score was also determined in all patients. Coronary collateral circulation was absent in 32 patients, whereas 68 patients had coronary collateral circulation. Patients with collateral grade A had greater left ventricular function score than did patients with collateral grade 0 (P = .048). However, there was no significant difference between P-wave dispersion of patients with and without coronary collateral circulation (P = .45). The presence of coronary collateral circulation failed to exert a beneficial decreasing effect on P-wave dispersion.

    Demographic characteristics of cases diagnosed with cleft palate
    (2020) Kaya, Huseyin; Guliyeva, Lale; Ozdemir, Ramazan; Gokce, Ismail Kursad; Deveci, Mehmet Fatih
    Aim: The aim of this study is to retrospectively evaluate the cleft palate cases in our neonatal clinic and to examine the associated clinical features, predisposing factors, accompanying anomalies, additional findings, treatment approaches and follow-up results.Material and Methods: The study included babies that were diagnosed with cleft palate in our Neonatal Intensive Care Unit between January 2014 and December 2018. The etiological risk factors, demographic characteristics, clinical features and concomitant malformations of the patients included in the study were retrospectively recorded from the patient files and the database system of our hospital.Results: A total of 70 cleft palate patients were observed over a five year period. Of these, 30 (42.9%) were female and 40 (57.1%) were male. The mean gestational age was 38 ± 2.9 weeks and the mean birth weight was 2845 ± 700 grams. 77.1% of the patients were found to additionally have cleft lips. 27 patients (38.5%) had cardiac defects, 18 (25.7%) had central nervous system anomalies and 4 (5.7%) had hypothyroidism. 24 (34.3%) of the parents were consanguineous. The median age at the time of the initial operation was 13 months for cleft palate cases and 5 months for cleft lip cases.Conclusion: As a result, treatment and follow-up of patients with cleft palate defect requires a multidisciplinary approach. These patients should undergo a thorough examination and evaluation. Since many syndromes or malformations may accompany the palate defects, these cases should be investigated with respect to genetic disease and other system anomalies.

    Development of severe hyponatremia due to cerebrospinal fluid leakage following meningomyelocele surgery in a newborn
    (Amer Assoc Neurological Surgeons, 2018) Gokce, Ismail Kursad; Turgut, Hatice; Ozdemir, Ramazan; Onal, Selami Cagatay
    Cerebrospinal fluid leakage following meningomyelocele surgery is a frequent complication in the wound healing period and is associated with wound dehiscence. CSF loss can cause severe hyponatremia, especially in the newborn and early infancy periods when dietary sodium content is relatively low. Hyponatremia in the newborn period can result in adverse neurodevelopmental outcomes. In addition, hyponatremia's cerebral effects can increase complications in neurosurgery patients. The authors present the case of a newborn in whom CSF leakage from the operative site and severe hyponatremia developed following meningomyelocele surgery. To the best of their knowledge, severe hyponatremia caused by CSF leakage after meningomyelocele surgery has not been previously reported in the literature.

    Dexpanthenol therapy reduces lung damage in a hyperoxic lung injury in neonatal rats
    (Taylor & Francis Ltd, 2016) Ozdemir, Ramazan; Demirtas, Gulsum; Parlakpinar, Hakan; Polat, Alaadin; Tanbag, Kevser; Taslidere, Elif; Karadag, Ahmet
    Objective: Dexpanthenol (Dxp) plays a major role in cellular defense and in repair systems against oxidative stress and inflammatory response and it has not yet been evaluated in treatment of bronchopulmonary dysplasia (BPD). We tested the hypothesis that proposes whether Dxp decreases the severity of lung injury in an animal model of BPD.Methods: Forty rat pups were divided into four groups: control, control+Dxp, hyperoxia and hyperoxia+Dxp. All animals were processed for lung histology and tissue analysis. The degree of lung inflammation, oxidative and antioxidant capacity was assessed from lung homogenates.Results: Lung injury score and alveol diameter increased in the hyperoxia group (p<0.001). Median level of malondialdehyde, total oxidant status and oxidative stress indexes was significantly higher in the hyperoxia group compared to the other groups. The median superoxide dismutase activity in the hyperoxia group was notably less than those of control+Dxp and hyperoxia+Dxp groups (p<0.01). Similarly, lung catalase, glutathione (GSH) peroxidase and reduced GSH activities in the hyperoxia group were significantly lower than other groups. Furthermore, the hyperoxia+Dxp group had lower tumor necrosis factor- and interleukin-1 median levels compared to the hyperoxia group (p=0.007).Conclusion: Dxp treatment results in less emphysematous change as well as decrease in inflammation and oxidative stress markers in an animal model of BPD.

    Diagnostic Contribution of Postmortem Needle Biopsies in Neonates
    (De Gruyter Open Ltd, 2013) Celiloglu, Ozgu Suna; Celiloglu, Can; Kurnaz, Erdal; Ozdemir, Ramazan; Karadag, Ahmet
    Objective: We examined the contribution of neonatal postmortem needle biopsy in circumstances of autopsy denial where magnetic resonance imaging cannot be performed. Material and Method: 247 postmortem needle biopsy specimens of 76 neonatal cases who died in the neonatal intensive care ward of a tertiary hospital between 2005 and 2010 and where the family did not give permission for an autopsy were retrospectively evaluated. Results: 90 needle biopsy attempts (36.4%) were unsuccessful among the 247 biopsies. Liver needle biopsies were found to yield the most valuable diagnostic contribution. A total of 53 liver biopsies provided clinical information that contributed to the diagnosis. Conclusion: The postmortem needle biopsy should be applied in all cases in which standard biopsy cannot be performed. Success rates and level of information gained by extrahepatic needle organ biopsies in neonates were found to be quite low whereas needle biopsies of the liver yielded valuable results. We believe it is more appropriate to perform percutaneous postmortem biopsies solely on the liver in neonates.

    Does Chrysin prevent severe lung damage in Hyperoxia-Induced lung injury Model?
    (Elsevier, 2021) Ozdemir, Ramazan; Gokce, Ismail Kursat; Taslidere, Asli Cetin; Tanbek, Kevser; Gul, Cemile Ceren; Sandal, Suleyman; Turgut, Hatice
    Background: Oxidative stress and inflammation play a critical role in the etiopathogenesis of bronchopulmonary dysplasia (BPD). The aim of this study was to evaluate the preventive effect of Chrysin (CH), an antioxidant, antiinflammatory, antiapoptotic and antifibrotic drug, on hyperoxia-induced lung injury in a neonatal rat model. Methods: Forty infant rats were divided into four groups labeled the Control, CH, BPD, and BPD + CH. The control and CH groups were kept in a normal room environment, while the BPD and BPD + CH groups were kept in a hyperoxic (90-95%) environment. At the end of the study, lung tissue was evaluated with respect to apoptosis, histopathological damage and alveolar macrophage score as well as oxidant capacity, antioxidant capacity, and inflammation. Results: Compared to the BPD + CH and control groups, the lung tissues of the BPD group displayed substantially higher levels of MDA, TOS, TNF-alpha, and IL-1 beta (p < 0.05). While the BPD + CH group showed similar levels of TNF-alpha, and IL-1 beta as the control group, MDA and TOS levels were higher than the control group, and significantly lower than the BPD group (p < 0.05). The BPD group exhibited considerably lower levels of TAS, SOD, GSH, and GSHPx in comparison to the control group (p < 0.05). The BPD and BPD + CH groups exhibited higher mean scores of histopathological damage and alveolar macrophage when compared to the control and CH groups (p <= 0.0001). Both scores were found to be lower in the BPD + CH group in comparison to the BPD group (p <= 0.0001). The BPD + CH group demonstrated a significantly lower average of TUNEL and caspase-3 positive cells than the BPD group. Conclusion: We found that prophylaxis with CH results in lower histopathological damage score and reduces apoptotic cell count, inflammation and oxidative stress while increasing anti-oxidant capacity.

    Early regular versus late selective poractant treatment in preterm infants born between 25 and 30 gestational weeks: a prospective randomized multicenter study
    (Taylor & Francis Ltd, 2014) Dilmen, Ugur; Ozdemir, Ramazan; Aksoy, Hatice Tatar; Uras, Nurdan; Demirel, Nihal; Kirimi, Ercan; Erdeve, Omer
    Objective: Surfactant treatment in the early hours of life significantly decreases the rates of death and air leak, and increases survival without bronchopulmonary dysplasia (BPD) in preterm infants. We aimed to compare the impact of early surfactant (ES) administration to late selective (LS) treatment on neonatal outcomes in preterm infants. Methods: All preterm infants between 25 and 30 wks gestational age and who were not entubated in the delivery room and did not have any major congenital malformation or perinatal asphyxia were randomized to ES treatment (200 mg/kg Curosurf (R) administration in 1 hour after birth) or LS treatment (200 mg/kg Curosurf (R) administration in the first 6 h of life if needed). The patients were treated by nasal continuous positive airway pressure (nCPAP) treatment regardless of the surfactant requirement. Outcomes were the necessity of mechanical ventilation, nCPAP duration, the oxygen requirement duration, the rates of BPD, retinopathy of prematurity (ROP) and mortality, and the assesment of the following situations; (pneumothorax, patent ductus arteriosus (PDA), necrotizing enterocolitis (NEC), and intraventricular hemorrhage (IVH) >= grade III). Results: Among 159 infants enrolled in the study, 79 were randomized to ES and 80 to LS treatment groups. Thirty-five patients (44%) in the LS treatment group needed surfactant administration. Necessity of second dose surfactant administration was 8.9% in the ES treatment group. Although necessity of mechanical ventilation, nCPAP duration, oxygen need duration, rates of PDA, NEC, BPD, ROP stage >3 and mortality did not show a significant difference between groups, the ES treatment group had lower rates of pneumothorax and IVH >= grade III when compared to the LS treatment group. Conclusions: ES treatment decreases IVH (>= grade III) and pneumothorax rates but does not have any effect on BPD when compared to LS.

    The effect of defect size on mortality and morbidity in patients with neural tube defect
    (2022) Turgut, Hatice; Ozdemir, Ramazan; Gokce, Ismail Kursad; Kaya, Huseyin; Onal, Selami Cagatay
    Aim: Neural tube defects (NTD) occur due to errors in the closing of neural canal in embryo. All over the world, the incidence of all forms of NTD varies between 1.4 and 2 in every 1000 live births. The aim of the present study was to investigate the short term prognosis, accompanying anomalies and complications in patients with NTD and to evaluate the relation between defect sizes. Material and Methods: Patients who applied to Inonu University Neonatology Department between January 2010 and December 2017 with the diagnosis of NTD and were operated on were included in the study. Babies who died within the first 24 hours were excluded from the study. Patients were divided into two groups according to the size of NTD; < 5 cm (Group 1) and ≥ 5 cm (Group 2). Approval for the study was obtained from local ethics committee. Results: Overall 133 infants were included in the study. Mean birth weight was 3155 ± 531 g and mean duration of pregnancy was on 38.1 ± 1.8 weeks. Of NTD’s 82% was located in lumbosacral region. 90.2% of the patients underwent operation within the first 24 hours. Parameters such as hydrocephalus, need for shunt, need for flap in tissue defects, the rate of postoperative complications, duration of hospitalization, mortality and the use of antibiotics were found to be at a higher rate in cases whose defect size was ≥5 cm than in those whose defect size was < 5 cm (p < 0.005). Postoperative complications developed in 48.1% of the patients. The most common complications were observed to be cerebrospinal fluid (CSF) leakage (24.1%) and bladder dysfunction (7.5%). Conclusion: In patients with NTD, as the size of the defect increases, additional interventions, complications, hospitalization rates and mortality increase as well. Therefore, it is recommended that health care personnel should take care against problems in the management of this group of patients and inform familes beforehand on these issues.

    Effect of treadmill exercise testing on P wave duration and dispersion in patients with isolated myocardial bridging
    (Springer, 2009) Barutcu, Irfan; Esen, Ali Metin; Ozdemir, Ramazan; Acikgoz, Nusret; Turkmen, Muhsin; Kirma, Cevat
    Several previous studies suggest that myocardial bridging (MB) is associated with ischemia and rhythm disturbances. We sought to examine exercise-induced changes in P wave duration and dispersion (PWD), the markers of atrial conduction abnormalities in patients with isolated MB of left anterior descending artery (LAD) and control subjects. Eighteen patients with MB of LAD (group-I) and 22 subjects with angiographically demonstrated normal coronary arteries (group-II) underwent treadmill exercise testing. Before and after exercise ECG was recorded at a paper speed of 50 mm/s. The change in maximum and minimum P wave duration was measured manually and difference between two values was defined as PWD. There was no difference between two groups in terms of demographic properties. Baseline maximum and minimum P wave duration and PWD durations were similar in both groups and they did not change after exercise. (Group-I: before and after test; 114 +/- A 10 vs. 114 +/- A 9, 66 +/- A 13 vs. 67 +/- A 10, and 47 +/- A 9 vs. 45 +/- A 13 ms, P > 0.05, group-II; 113 +/- A 9 vs. 115 +/- A 8, 68 +/- A 11 vs. 68 +/- A 11, 45 +/- A 11 vs. 48 +/- A 15 ms for each, respectively). In addition there was no significant correlation between PWD and P wave duration and echocardiographic variables. In patients with MB of LAD, PWD and P wave duration were not different than healthy subjects and treadmill exercise testing did not induce atrial conduction abnormalities in both groups.
