    22nd Annual Congress of the European-Paediatric-Surgical-Association (EUPSA) -- SEP 01-04, 2021 -- Athens, GREECEBackground. There is limited information about the prevalence and risk factors of inguinal hernia and undescended testis in patients with spina bifida (SB). The aim of this study was to identify the properties and prevalence of inguinoscrotal diseases in these patients. Methods. A questionnaire was completed by parents of patients with the diagnosis of SB in our center. Together with demographic data, presence an of inguinal hernia, side, operation history, presence of ventriculoperitoneal (VP) shunt, type of SB aperta or occulta, recurrence and presence of undescended testis were questioned. Patients were grouped into 2 as SB aperta and occulta. The prevalence of these pathologies and their clinical properties were evaluated. Results. In this study, 388 patients were evaluated. Of these, 238 patients had SB aperta and 150, SB occulta. There was no significance in comparison of gender. The prevalence of inguinal hernia was 12.6% in general. A hernia was noted in 37 SB aperta patients (15.6%) whereas this was seen in 12 of the SB occulta patients (8%) (p=0.029). When there was a VP shunt, hernia prevalence was 21.5% and when there was no shunt, this ratio was 7.1% (p=0.0001). Prevalence of inguinal hernia was 21.8% in males and 3.2% in females (p=0.0001). When there was a VP shunt with SB aperta the prevalence was 21.9% and when a VP shunt was present with SB occulta, this number was found to be 13.3% (p=0.006). The prevalence of undescended testis was 17.7% and there was no difference between SB aperta and occulta patients. Conclusions. Inguinal hernia and undescended testis are more frequent in SB patients when compared to the normal population. VP shunts and male gender may be risk factors for inguinal hernia in these children. These findings may imply neurological factors in the etiology of inguinal hernia and undescended testis.European Paediat Surg Asso

    Burkitt lymphoma with a granulomatous reaction: an M1/Th1-polarised microenvironment is associated with controlled growth and spontaneous regression

    Aims Burkitt lymphoma (BL) is an aggressive B-cell lymphoma that, in some instances, may show a granulomatous reaction associated with a favourable prognosis and occasional spontaneous regression. In the present study, we aimed to define the tumour microenvironment (TME) in four such cases, two of which regressed spontaneously. Methods and results All cases showed aggregates of tumour cells with the typical morphology, molecular cytogenetics and immunophenotype of BL surrounded by a florid epithelioid granulomatous reaction. All four cases were Epstein-Barr virus (EBV)-positive with type I latency. Investigation of the TME showed similar features in all four cases. The analysis revealed a proinflammatory response triggered by Th1 lymphocytes and M1 polarised macrophages encircling the neoplastic cells with a peculiar topographic distribution. Conclusions Our data provide an in-vivo picture of the role that specific immune cell subsets might play during the early phase of BL, which may be capable of maintaining the tumour in a self-limited state or inducing its regression. These novel results may provide insights into new potential therapeutic avenues in EBV-positive BL patients in the era of cellular immunotherapy

    The protective effect of medroxyprogesterone acetate on propionic acid induced autism in rats was evaluated. For this purpose, 30 rats were divided into three groups. The significant difference in the levels of IL-17 (p<0.05), IL 2 (p<0.05), and TNF-?? (p<0.05), lactate (p<0.05), and nerve growth factor (p<0.05) were found in the medroxyprogesterone-treated group by biochemical analysis. In histopathological examination, the medroxyprogesteronetreated group revealed significant improvement in neural body degeneration, neural count, and dysmorphological changes in both CA1 and CA3 regions. Immunohistochemical examination revealed improvement in glial activity with glial fibrillar acidic protein and morphological changes in Purkinje cells. Magnetic resonance spectroscopy showed an improvement in the level of lactate duplets in the medroxyprogesterone-treated group. To our knowledge, this is the first study, to evaluate the protective effect of medroxyprogesterone on propionic acid-induced autism in rats

    The Importance of Lumbar Curve Flexibility and Apical Vertebral Rotation for the Prediction of Spontaneous Lumbar Curve Correction in Selective Thoracic Fusion for Lenke Type 1 and 2 C Curves: Retrospective Cohort Study with a Mean Follow-Up of More than 10 years

    No full text
    Study Design: Retrospective analysis of a prospectively collected data. Objective: Lumbar flexibility(LF) is generally defined with preoperative side bending films;it is not clear what percentage of LF predicts the spontaneous lumbar curve correction (SLCC) at long term follow up. Aim of this study was to find out cut-off value of preoperative LF,apical vertebra rotation(AVR) and apical vertebral translation(AVT);which may predict more than 50% SLCC. Methods: Patients with Lenke 1C&2C curves,treated with posterior STF,with a minimum 10 years follow up were included.The patients who had more than 50% SLCC(Group A) or less than 50% (Group B) were compared in terms of LF,AVR and AVT to understand a cut-off value of those parameters.Statistically, Receiver Operating Characteristic(ROC) test was used. Results: Fifty five AIS patients (54F, 1M) with mean age 14 (11-17) were included to study.Thoracic curve correction rate was 75%;lumbar curve correction rate was 59% at the latest follow up.Group A included 45(82%) patients at the latest follow up.Three patients (5%) showed coronal decompensation at early postop and 2 of them became compensated at f/up.ROC analyses showed 69% flexibility as the cut-off value for SLCC (P < .01).The difference between groups in terms of preop mean AVRs was significant (P = .029) (Group A = 1.9; Group B = 2.4). Conclusion: In Lenke 1C&2C curves,whenever LF on the preoperative bending x-ray is greater than 70% (P < .0 1 )and AVR is equal or less than grade 2,STF provides satisfactory clinical and radiological SLCC with more than mean 10 years f/up.This flexibility rate and apical vertebral rotation can be helpful in decision making for successful STF

    A novel adsorbent, 3-phenyl-1-(2-pyridyl)thiourea (PPTU) was synthesized and its adsorption capabilities were studied for Cu(II), Cd(II), Ni(II), Pb(II) and Fe(II) cations in the waters such as tap and polluted seawaters. The kinetics, Langmuir and Freundlich isotherms were discussed related to the adsorptions. The adsorption capacities of PPTU were found 9.4; 12.6; 90.9; 57.1 and 30.4 mg g(-1) and preconcentration with PPTU including the FAAS step yielded the LOQ values 0.46; 2.65; 1.12; 2.65 and 1.72 ng mL(-1) for Cu(II), Cd(II), Ni(II), Pb(II) and Fe(II), respectively. The adsorbent after the elutions and washings could be reused three times in the next adsorptions. The interferences on the adsorptions arising from the major cations of the seawater and the usability of PPTU for interested metals in the seawater were discussed. The proposed method is simple with highly efficient and green preconcentration procedure for trace analysis of the target metal ions

    The aim of this study was to investigate the effect of Madopar on the absence seizures and the anxiety-like behavior (assessed using the open field test) in Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats. Twenty-eight male WAG/Rij rats were randomly divided into four groups: group I: control; group II: Madopar 5 mg/kg; group III: Madopar 50 mg/kg; group IV: Madopar 100 mg/kg. A tripolar electrode was attached to all WAG/Rij rats. Electrocorticography (ECoG) recordings were made before and after Madopar (5, 50, and 100 mg/kg) injection for three hours. Anxiety-related behavior was studied using the open field test for 5 min after the ECoG recordings. Madopar significantly reduced the number and duration of spike-wave discharges (SWDs) when compared to the control group. The highest dose of Madopar (100 mg/kg) significantly reduced the duration of SWDs when compared to Madopar (5 mg/kg). All Madopar doses did not alter the duration of grooming, but the highest doses of Madopar significantly increased the number of squares crossed in the open field test when compared to the control and Madopar (5 mg/kg) groups. These results revealed that Madopar reduced the absence-like seizures and the anxiety-related behavior in WAG/Rij rats. This may emphasize the therapeutic properties of the Madopar/L-dopa in absence epilepsy

    The benefit of breast magnetic resonance imaging (MRI) in breast-conserving surgery (BCS) is unclear. Our study compared breast cancer patients with and without preoperative breast MRI and their long-term oncologic outcomes are reported. A total of 1378 BCS cases with early breast cancer between 1996 and 2017 were reviewed. Patients with carcinoma in situ or neoadjuvant treatment or having breast MRI after tumor excision were excluded. Of 1378 patients, 270 (19.5%) had preoperative MRI. There were no significant differences regarding T and N stage and molecular subtypes between the groups. Surgical margins were significantly wider in the breast MRI group. Five-year overall survival (OS) was 96.9% in the MRI group and 94.3% in the control group, and this difference was not significant (p=0.11). Five-year local-regional recurrence-free survival (LRFS) was not significantly different either (98.8% and 96.5%, respectively, p=0.41). When analyses were repeated only for patients with hormone receptor-negative or triple-negative breast cancer, there was still no significant difference in OS, LRFS, or disease-free survival. In conclusion, MRI does not seem necessary in all patients undergoing BCS. New prospective randomized controlled trials are needed to determine appropriate use of preoperative MRI and its effects on oncologic outcomes in early breast cancer patients

    No full text
    Background: Transcutaneous electrogastrography is a novel modality to assess the human stomach's gastric myoelectrical activity. The purpose of this study was to compare functional dyspepsia, joint hypermobility, and diabetic gastroparesis patients with healthy control subjects in terms of gastric motility abnormalities through electrogastrography evaluations, and to then evaluate the correlation among variations in their blood parameters. Methods: This study analyzed 120 subjects with functional dyspepsia (n = 30), joint hypermobility (n = 30), diabetic gastroparesis (n = 30), and control subjects (n = 30). The electrogastrography parameters included the dominant frequency, dominant power, power ratio, and instability coefficient, which were analyzed preprandially and postprandially. Although there are similar studies in the literature, there is no other study in which all groups have been studied together, as in our study. Results: The electrogastrography results showed that preprandial dominant frequency (P = .031*) dominant power (P = .047*) and instability coefficient (P = .043*) and postprandial dominant frequency (P = .041*) and dominant power (P = .035*) results were statistically significant among the functional dyspepsia, joint hypermobility, diabetic gastroparesis, and control groups. There was no significant difference found in terms of power ratio (P= .114) values. However, only glucose (P = .04*) and calcium (P = .04*) levels showed statistical significance. Several blood tests including hemoglobin (P = .032*) creatinine (P= .045*) calcium (P = .037*), potassium (P= .041*), white blood cells (P = .038*), and alanine aminotransferase (P = .031*) also showed correlation with the dominant frequency, power ratio, and instability coefficient parameters. Conclusions: This joint methodology demonstrated that it is possible to differentiate between functional dyspepsia, joint hypermobility, and diabetic gastroparesis patients from healthy subjects by using electrogastrogrophy. Moreover, the majority of patients showed dequate gastric motility in response to food.Scientific and Technological Research Council of Turkey - TUBITAK [113E605]This work was performed under the 113E605 project supported by The Scientific and Technological Research Council of Turkey - TUBITAK

    Introduction The aim of this study was to translate, linguistically validate, and evaluate the psychometric properties of the Shortened Xerostomia Inventory (SXI) among Turkish patients undergoing hemodialysis (HD). Methods The study was conducted with 81 chronic HD patients in the HD units of two state hospitals between June and August 2020. Explanatory factor analysis was implemented to test the construct validity. In addition, the test-retest method was performed to test the reliability and consistency of the scale over time. Results A total of 81 patients participated in the study. The Cronbach's alpha coefficient of SXI was 0.788. The mean values for the test were 12.84 +/- 6.78 and re-test scores was 11.03 +/- 6.88. Intraclass correlation coefficient value calculated as 0.992 and accordingly a statistically significant relationship between the test and retest scores (p < 0.001). Conclusions Our study showed that the SXI is a valid and reliable measurement tool for Turkish HD patients
