Abstract
BACKGROUND Hypoxic ischemic encephalopathy (HIE) is a significant cause of mortality and short- and long-term morbidities. Therapeutic hypothermia (TH) has been shown to be the standard care for HIE of infants ≥36 weeks gestational age (GA), as it has been demonstrated to reduce the rates of mortality, and adverse neurodevelopmental outcomes. This study aims to determine the incidence of HIE in our country, to assess the TH management in infants with HIE, and present short-term outcomes of these infants. METHODS The Turkish Hypoxic Ischemic Encephalopathy Online Registry database was established for this multicenter, prospective, observational, nationally-based cohort study to evaluate the data of infants born at ≥34 weeks GA who displayed evidence of neonatal encephalopathy (NE) between March, 2020 and April 2022. RESULTS The incidence of HIE among infants born at ≥36 weeks GA (n = 965) was 2.13 per 1000 live births (517:242440), and accounting for 1.55% (965:62062) of all neonatal intensive care unit admissions. The rates of mild, moderate and severe HİE were 25.5% (n = 246), 58.9% (n = 568), and 15.6% (n = 151), respectively. Infants with severe HIE had higher rates of abnormal magnetic resonance imaging (MRI) findings, and mortality (p<0.001). No significant difference in mortality and abnormal MRI results was found according to the time of TH initiation (<3 h, 3-6 h and >6 h) (p>0.05). TH was administered to 85 (34.5%) infants with mild HIE, and of those born of 34-35 weeks of GA, 67.4% (n = 31) received TH. A total of 58 (6%) deaths were reported with a higher mortality rate in infants born at 34-35 weeks of GA (OR 3.941, 95% Cl 1.446-10.7422, p = 0.007). CONCLUSION The incidence of HIE remained similar over time with a reduction in mortality rate. The timing of TH initiation, whether <3 or 3-6 h, did not result in lower occurrences of brain lesions on MRI or mortality. An increasing number of infants with mild HIE and late preterm infants with HIE are receiving TH; however, the indications for TH require further clarification. Longer follow-up studies are necessary for this vulnerable population.

Abstract
Background Lymphatic malformations (LMs) are rare congenital anomalies. The traditional treatment is surgical excision, but intralesional sclerosing agent injection is also preferred as the first-choice treatment because of postoperative frequent recurrences, poor cosmetic results, and high complication rate. We aimed to evaluate the efficacy of sclerosing agent injection used in the treatment of LMs in children. Materials and Methods We retrospectively analyzed the children who were treated for LM between January 2011 and January 2022. The lesion sizes of the patients who were injected with sclerosant (Bleomycin) under sedation anesthesia, measured by ultrasound before and after the treatment, were recorded, and the difference between them was statistically evaluated. Results Fifteen patients were retrospectively analyzed. The mean age was 45.2 ± 14.1 months. Of these, ten (66.6%) were male and five (33.3%) were female (F/M = 1/2). The mean age of male patients was 55 ± 20.1 months; the mean age of female patients was 25.8 ± 11. Seven patients had a single dose, two had twice, and six had three and more. The mean measurable size of macrocystic lesions before treatment was 55.2 ± 28.4 mm; after treatment, it was 23.8 ± 18.2 mm. Although no measurable shrinkage was detected in microcystic lesions, it was observed that the lesion shrank to allow surgical resection. With the statistical analysis, it was seen that there was a statistically significant difference between the dimensions before and after the treatment (P < 0.05) and the sclerosant injection had a great effect on the treatment (R: 0.89). Conclusion Intralesional injection of bleomycin is less effective for microcystic or mixed-type LMs, but provides an effective reduction for a safe surgical procedure. It is an effective treatment for macrocystic lesions.

Abstract
BACKGROUND Multiple myeloma (MM), characterized by extensive genomic instability and aberrant DNA damage repair, is a plasma cell malignancy due to the excessive proliferation of monoclonal antibody-producing plasma cells in the bone marrow. Despite the significant improvement in the survival of patients with the development of novel therapeutic agents, MM remains an incurable disease. Werner (WRN) helicase, a member of the RecQ helicase family that contributes to DNA replication, recombination, and repair, has been highlighted in cancer cell survival, yet the role and mechanism of WRN in MM remain unclear. METHODS AND RESULTS Increased mRNA expression of WRN in newly diagnosed and relapsed CD138+ myeloma plasma cells than normal CD138+ plasma cells and their matched CD138- non-tumorigenic cells were detected by qPCR. Using NSC19630, a specific WRN helicase inhibitor, we further showed decreased cell viability, proliferation, and DNA repair and increased DNA damage and apoptosis in MM cells by MTT assay, cell cycle assay, apoptosis assay, and Western blotting. CONCLUSIONS The results of the present study demonstrate that WRN is essential in MM cell viability, proliferation, and genomic stability, indicating its inhibition may enhance the efficacy of chemotherapy in MM.

Abstract
BACKGROUND Mucormycosis is an emerging aggressive mold infection. This study aimed to assess the outcome of hospitalized adults with rhino-orbito-cerebral mucormycosis (ROCM). The secondary objective was to identify prognostic factors in this setting. METHODS This study was an international, retrospective, multicenter study. Patients' data were collected from 29 referral centers in 6 countries. All qualified as "proven cases" according to the EORTC/MSGERC criteria. RESULTS We included 74 consecutive adult patients hospitalized with ROCM. Rhino-orbito-cerebral type infection was the most common presentation (n = 43; 58.1%) followed by rhino-orbital type (n = 31; 41.9%). Twenty (27%) had acquired nosocomial bacterial infections. A total of 59 (79.7%) patients (16 in combination) received appropriate antifungal treatment with high-doses of liposomal amphotericin B. Fifty-six patients (75.7%) underwent curative surgery. Thirty-five (47.3%) required intensive care unit admission (27; 36.5% under mechanical ventilation). Hospital survival was 56.8%, being reduced to 7.4% in patients with invasive mechanical ventilation. A multivariate binary backward logistic regression model identified confusion at admission (OR 11.48), overlapping hospital-acquired infection (OR 10.27), use of antifungal treatment before diagnosis (OR 10.20), no surgical debridement (OR 5.92), and the absence of prior sinusitis (OR 6.32) were independently associated with increased risk for death. CONCLUSION Today, ROCM still has high mortality rate. Improving source control, rational therpy, and preventing nosocomial infections may improve survival in this severe infection.

Abstract
Coronavirus disease-2019 continues to have a serious impact in countries with the effect of new variant viruses emerging with mutations. While the effectiveness and protection of the vaccine have been determined all over the world, some vaccine-related side effects can be detected in the form of cases. In our case, the patient was admitted to the emergency department of our hospital with complaints of weakness and progressive rash on his legs. Diffuse petechiae purpura on the legs of the patient was observed and complete blood count revealed thrombocytopenia. Peripheral blood smear supported the blood count test results with thrombocytopenia, secondary causes of thrombocytopenia were excluded, and the patient was diagnosed with vaccine-induced immune thrombocytopenia.

Abstract
OBJECTIVES This study aimed to investigate the frequency and status of depression and anxiety among mothers of children with inborn errors of metabolism (IEM) who were on a restricted diet and previously experienced metabolic crises. METHODS This cross-sectional multicenter descriptive study included 93 children with IEM who were on restricted diet. The patients were divided into two groups: those who had experienced metabolic crises (n=44, urea cycle defect, organic acidemia, maple syrup urine disease, hereditary fructose intolerance) and those who had not experienced previous metabolic crises (n=49; phenylketonuria, galactosemia, and non-ketotic hyperglycinemia). The control group comprised 37 healthy children. The mothers of the patients and control participants answered a questionnaire about their and their children's demographic and clinical characteristics and completed the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI-S and STAI-T). RESULTS The maternal BDI, STAI-S, and STAI-T scores were 6.3±5.2, 36.1±11.2, and 39.9±8.8, respectively, in the control group. The maternal BDI, STAI-S, and STAI-T scores of the children who had experienced (19.2±9.7; 44.0±12.4; 47.9±10.6) and those who had not experienced (13.9±9.1; 40.7 ±8.6; 45.3±8.3) a crisis were significantly higher than for the controls. The BDI score was significantly higher for the mothers of children who had experienced a crisis (p=0.011), whereas no significant difference was determined between the two patient groups regarding STAI-S and STAI-T scores. The mothers of four children who had experienced metabolic crises were on antidepressant therapy. CONCLUSION Although their children were on a similar restricted diet, the mothers of children who previously experienced or who had the risk of experiencing metabolic crises had higher depression scores as compared with the mothers of children who did not experience a previous crisis. Early supportive therapy may be required for the families of these patients to lower the burden of stress.

Abstract
NK (Natural Killer) cell-mediated adoptive immunotherapy has gained attention in hematology due to the progressing knowledge of NK cell receptor structure, biology and function. Today, challenges related to NK cell expansion and persistence in vivo as well as low cytotoxicity have been mostly overcome by pioneering trials that focused on harnessing NK cell functions. Recent technological advancements in gene delivery, gene editing and chimeric antigen receptors (CARs) have made it possible to generate genetically modified NK cells that enhance the anti-tumor efficacy and represent suitable “off-the-shelf” products with fewer side effects. In this review, we highlight recent advances in NK cell biology along with current approaches for potentiating NK cell proliferation and activity, redirecting NK cells using CARs and optimizing the procedure to manufacture clinical-grade NK and CAR NK cells for adoptive immunotherapy.

Abstract
INTRODUCTION Flexible bronchoscopy (FB) is frequently used for assessment and treatment of patients with respiratory diseases. Our aim was to investigate the contribution of FB to diagnosis and therapy in children admitted to the intensive care units (ICU) and to evaluate the safety of FB in this vulnerable population. METHODS Children less than 18 years of age who underwent FB in the five neonatal and pediatric ICUs in Istanbul between July 1st, 2015 and July 1st, 2020 were included to the study. Demographic and clinical data including bronchoscopy indications, findings, complications, and the contribution of bronchoscopy to the management were retrospectively reviewed. RESULTS One hundred and ninety-six patients were included to the study. The median age was 5 months (range 0.3-205 months). The most common indication of FB was extubation failure (38.3%), followed by suspected airway disease. Bronchoscopic assessments revealed at least one abnormality in 90.8% patients. The most common findings were airway malacia and the presence of excessive airway secretions (47.4% and 35.7%, respectively). Positive contribution of FB was identified in 87.2% of the patients. FB had greater than 1 positive contribution in 138 patients and 80.6% of the patients received a new diagnosis. Medical therapy was modified after the procedure in 39.8% and surgical interventions were pursued in 40% of the patients. Therapeutic lavage was achieved in 18.9%. There were no major complications. CONCLUSION Flexible bronchoscopy is a valuable diagnostic and therapeutic tool in neonatal and pediatric ICUs and is not associated with major complications.

Abstract
OBJECTIVES Hereditary fructose intolerance (HFI) is an autosomal recessive disorder caused by a deficiency in aldolase B that can result in hypoglycemia, nausea, vomiting, abdominal pain, liver and kidney dysfunction, coma, and even death. This study aims to represent the clinical features and molecular genetic analysis data of the patients diagnosed with HFI in our study population. METHODS The medical records of the 26 patients with HFI were evaluated retrospectively. Age, gender, clinical findings, metabolic crises, and the results of molecular analyses were recorded. RESULTS The patients with HFI had a good prognosis and the aversion to sugar-containing foods was the main complaint. Seven different variants were identified in the Aldolase B (ALDOB) gene in HFI patients. The most frequent mutations were p.Ala150Pro, p.Ala175Asp had a prevalence of 61 and 30%, respectively, in agreement with the literature and other known variants were found with minor frequencies c.360-363del4(3.8%), p.Asn335Lys(3.8%), and three novel mutations c.113-1_15del4 (3.8%), p.Ala338Val(7.6%), and p.Asp156His(3.8%) were identified at a heterozygous, homozygous, or compound heterozygous level. CONCLUSIONS This study results revealed three novel mutations in patients with HFI. On the basis of age of presentation, clinical symptoms, and metabolic crisis, there was no clear-cut genotype-phenotype correlation. This article also demonstrates the importance of screening suspected infants in cases of acute liver failure for prompt diagnosis and treatment of HFI.

Abstract
BACKGROUND The clinical picture of COVID-19 shows significant similarity with influenza. In this study, it was aimed to compare the clinical and laboratory findings between pediatric patients diagnosed with COVID-19 and those with influenza A or B, and to obtain data on the differential diagnosis of COVID-19 from influenza in children. METHODS The study included 104 patients with COVID-19, 140 patients with influenza A and 135 patients with in-fluenza B (379 patients in total) who were admitted to our tertiary hospital with symptoms of acute respiratory tract infection. RESULTS Fever, cough, runny nose, and pharyngeal hyperemia rates were significantly lower in patients with COVID-19 than in those with influenza A/B. The highest leukocytosis and lymphocytosis rates were seen in influenza A patients. Eosinophil levels were found significantly lower in the influenza A/B patients compared to the COVID-19 group. C-reactive protein levels were significantly higher in the influenza A/B group when compared with the COVID-19 group. The mean PDW value was significantly higher in the COVID-19 patients compared to influenza A/B. CONCLUSIONS Our study data show that low body temperature and loss of taste and smell support the diagnosis of COVID-19, and fever, cough, pharyngeal hyperemia, and runny nose support the diagnosis of influenza. While leukocytosis and increased C-reactive protein suggest influenza, high PDW and eosinophil levels support COVID-19.

Abstract
Idiopathic pulmonary fibrosis (IPF) is the most common and most deadly form of interstitial lung disease. Osteopontin (OPN), a matricellular protein with proinflammatory and profibrotic properties, plays a major role in several fibrotic diseases, including IPF; OPN is highly upregulated in patients' lung samples. In this study, we knocked down OPN in a bleomycin (BLM)-induced pulmonary fibrosis (PF) mouse model using small interfering RNA (siRNA) to determine whether the use of OPN siRNA is an effective therapeutic strategy for IPF. We found that fibrosing areas were significantly smaller in specimens from OPN siRNA-treated mice. The number of alveolar macrophages, neutrophils, and lymphocytes in bronchoalveolar lavage fluid was also reduced in OPN siRNA-treated mice. Regarding the expression of epithelial-mesenchymal transition (EMT)-related proteins, the administration of OPN-siRNA to BLM-treated mice upregulated E-cadherin expression and downregulated vimentin expression. Moreover, in vitro, we incubated the human alveolar adenocarcinoma cell line A549 with transforming growth factor (TGF)-β1 and subsequently transfected the cells with OPN siRNA. We found a significant upregulation of Col1A1, fibronectin, and vimentin after TGF-β1 stimulation in A549 cells. In contrast, a downregulation of Col1A1, fibronectin, and vimentin mRNA levels was observed in TGF-β1-stimulated OPN knockdown A549 cells. Therefore, the downregulation of OPN effectively reduced pulmonary fibrotic and EMT changes both in vitro and in vivo. Altogether, our results indicate that OPN siRNA exerts a protective effect on BLM-induced PF in mice. Our results provide a basis for the development of novel targeted therapeutic strategies for IPF.

Abstract
Alkaptonuria (AKU) is an inborn error of metabolism caused by the deficiency of homogentisate 1,2-dioxygenase (HGD) as a result of a defect in the HGD gene. HGD enzyme deficiency results in accumulation of homogentisic acid (HGA) in the body, which in turn leads to multisystemic clinical symptoms. The present study aimed to investigate the presenting symptoms, age at diagnosis, and clinical and genetic characteristics of AKU patients followed-up in different centers in Turkey. In this cross-sectional, multicenter, descriptive study, medical records of 66 AKU patients were retrospectively evaluated. Patients' data regarding demographic, clinical and genetic characteristics were recorded. HGD database (http://hgddatabase.cvtisr.sk/) was used to identify HGD gene variants. Of the patients, 37 (56.1%) presented with isolated dark urine and 29 (43.9%) were diagnosed based on the clinical symptoms or family screening. One of these patients was on follow-up for 2 years due to Parkinsonism and was diagnosed with AKU on further analyses. Signs of ochronosis such as joint pain, low back pain and renal stones developed in childhood in 7 patients. Eight patients were diagnosed with depression via psychiatric evaluation. There were 14 (21.2%) patients operated on for ochronosis. The most frequent mutation observed in the patients was c.175delA, which was followed by c.674G > A and c.1007-2A > T mutations. Four novel mutations (c.189G > A, c.549+1G > T, c.1188+1G > A, and c.334 T > G) were identified in the patients included in the study. In addition to the known signs such as dark urine and skin pigmentation, symptoms involving different systems such as neurological findings and depression can also be encountered in AKU patients. The presence of a change in urine color needs to be questioned in patients presenting with different symptoms such as arthralgia/arthritis, renal stones or low-back pain, particularly in childhood, when skin ochronosis is not pronounced, and further examination should be performed.

Abstract
Background and Objective: Umbilical cord blood which can be obtained by a non-invasive method can be informative about the clinical status of the newborn. It was aimed to establish reference intervals for umbilical cord blood parameters, and to compare complete blood count results between umbilical cord and venous blood samples in this study. Methods: This study was conducted at Medipol University Sefaköy Hospital, Department of Pediatrics, Istanbul, Turkey. A total of 1898 newborns who were born in a two-year period between January 2018 and December 2019 were included in the study. Venous blood samples were taken from 184 of them, and umbilical cord blood samples were taken from 1714 newborns. Results: The percentiles were determined according to gender and delivery method for the hematological parameters of umbilical cord blood. While mean platelet, eosinophil and mean corpuscular volume values were similar between the groups (p>0.05 for each), and significant differences were found between the groups in terms of all other mean hematological parameters (p<0.05 for each). Conclusion: The results of the complete blood count of umbilical cord blood samples can provide reliable information about the newborn. There are significant differences between umbilical cord and venous blood samples in terms of hematological parameters. For these reasons, it is necessary to determine reliable value ranges for umbilical cord blood hematological parameters in newborns. Data of our study can be a guide for further studies and clinicians.

Abstract
BACKGROUND Intravenous recombinant enzyme replacement therapy (ERT) is currently available for 8 lysosomal diseases. Hypersensitivity reactions (HSRs) may be observed during this long-term treatment. OBJECTIVE To evaluate the frequency and clinical treatment features of ERT HSRs and the management of desensitizations in children. METHODS Medical records were reviewed retrospectively for patients who received ERT. Those who had experienced HSRs to ERT were included in the study. The demographic characteristics of the patients, culprit enzyme, signs and symptoms, diagnostic tests, management of the reaction, and the protocol employed for the maintenance of ERT were recorded. RESULTS During the study period, 54 patients received ERT in our institution. A total of 11 patients (20.4%) experienced HSR to ERT. All reactions were of immediate type. The most common symptoms were cutaneous manifestations. A total of 9 patients experienced urticaria, and 2 had anaphylaxis as initial reaction. Patients who had isolated cutaneous symptoms continued their treatments with antihistamines, corticosteroid premedication, slower infusion rate or both. Patients who had recurrent urticaria with these modalities or those who had anaphylaxis continued their ERT with desensitization (n = 8). A total of 3 patients required revisions in desensitization protocols because of recurrent anaphylaxis. CONCLUSION The reactions that develop during this long-term treatment may be treated by premedication-prolonged infusion, but in some patients, desensitization protocols are necessary for the continuation of therapy. Revisions in desensitization protocols may be required.

Abstract
Anaplastic thyroid cancer (ATC) remains a cancer with one of the worst prognoses, despite novel targeted therapies. The median survival rate has not improved for decades. Epithelial-to-mesenchymal transition (EMT) is a crucial step in physiological processes and in cancer progression, but the underlying mechanisms are not yet fully understood. The current study examined the role of microRNA (miR)-200b in mesenchymal-to-epithelial transition in ATC. Total RNA and miR isolation were performed from ATC cell lines transfected with a miR-200b mimic. After miR-200b mimic transfection, expression levels of E-cadherin, vimentin and zinc finger E-box binding homeobox 1 (ZEB1) were confirmed by reverse transcription-quantitative PCR and western blotting. Additionally, cell migration was evaluated using miR-200b mimic and scrambled negative control-transfected cells. A total of 14 human ATC and 15 non-cancerous human thyroid tissues were immunohistochemically stained and scored as controls for E-cadherin, vimentin and ZEB1. In ATC tissues and cell lines, the mesenchymal marker ZEB1 was significantly upregulated and the epithelial marker E-cadherin was significantly downregulated. Additionally, the mesenchymal marker vimentin was significantly upregulated in ATC tissues and in one ATC cell line. MiR-200b mimic transfection significantly increased vimentin and ZEB1 expression, but E-cadherin expression remained below the measurement sensitivity. Furthermore, miR-200b overexpression decreased cell migration. The current study suggested that miR-200b may regulate the expression levels of mesenchymal markers such as vimentin and ZEB1 in ATC and may promote mesenchymal-to-epithelial transition.

Abstract
Purpose Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and poor prognostic hematological malignancy. There is still no standard treatment established for BPDCN patients. We aim to summarize the main clinical, biological features and treatment of 9 BPDCN patients. Methods Nine patients with BPDCN who had been diagnosed between July 2008 and December 2018 in Ankara University School of Medicine, were retrospectively evaluated. Results All patients (n = 9) were male, median age was 64 (21-80). Five patients (55.6%) had bone marrow infiltration, 5 patients (55.6%) cutaneous lesions, 6 patients (66.7%) lymph node involvement, 2 patients (22.2%) central nervous system involvement and 2 patients (22.2%) spleen involvement at time of diagnosis. Complex karyotype was observed in 2 patients. CHOP was given to 5 patients (55.6%), hyper-CVAD to 2 patients (22.2%), fludarabine, cyclophosphamide and mitoxantrone to 1 patient (11.1%) and cyclophosphamide, etoposide, methylprednisolone to 1 patient (11.1%) as first line chemotherapy. Four patients (44.4%) underwent allogeneic hematopoietic stem cell transplantation (AHSCT) in complete remission (CR) 1. Venetoclax was given to a transplant ineligible patient who had skin and lymph node involvement, with the off-label use. The median follow-up time was 15.9 months (3-48.6 months). Estimated median overall survival was 15.9 + 1.6 (95% CI 12.7-19.1) months. Conclusion Intensive induction therapies followed by AHSCT in CR seems to be best approaches for patients with BPDCN. Thus, more effective treatment strategies particularly targeted therapies should be warranted to improve the survival of patients with this rare disease.

Abstract
Objective To determine the ideal method for postoperative pain management after circumcision by comparing the most frequently used different methods like; dorsal penile block, caudal epidural block, subcutaneous ring block, intravenous paracetamol and intravenous tramadol HCl. Methods Between May 1st 2015 to May 1st 2016, 500 children between 2-10 year old were circumcised at the department of pediatric surgery of Istanbul Medipol University Health Care Practice & Research Center Sefakoy Hospital. Five groups were formed according to postoperative analgesia methods which were planned to be compared; Group-I. penile block, Group-II. Caudal epidural block, Group-III. subcutaneous ring block, Group-IV as intravenous paracetamol and Group-V as intravenous tramadol HCl. In order to evaluate the postoperative pain levels of children, Children's Hospital Eastern Ontario Pain Scale (CHEOPS) was filled at 30, 60, 120, 180 minutes after circumcision by a researcher who does not know which method was applied. Results No significant difference is found between the groups (p>0.05). In the statistical analysis, no significant difference was found in the effect of analgesia methods on CHEOPS scores between 30, 60, 120 and 180 minutes (p>0.05). In parallel with this result, no significant difference was found in the effect of heart beat rates and respiration rate averages between 30, 60, 120 and 180 minutes (p>0.05). Conclusion It has been shown that none of the five method has any superiority in reducing pain after circumcision and that all five methods can be used. However, we think that side effects of regional anesthesia and systemic analgesic applications should not be ignored.

Abstract
INTRODUCTION The cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) is an uncommon subtype of PTC, and it is associated with familial adenomatous polyposis (FAP). PRESENTATION OF CASE We describe a 32-year-old female who presented recurrent CMV-PTC with FAP. Surgery performed after the recurrent disease resulted in left recurrent laryngeal nerve palsy due to formation of strong scar after initial operation. The histopathological examination revealed the recurrent CMV-PTC without thyroid capsular invasion in remnant thyroid tissue of berry ligament. In addition, the immunohistochemical analysis showed that β-Catenin was diffusely positive in both cytoplasm and nucleus in CMV-PTC tissue. CONCLUSION Total thyroidectomy in CMV-PTC with FAP should be performed at initial surgery due to high recurrence.

Abstract
The underlying mechanisms of resistance to chemoradiotherapy of human papilloma virus (HPV)-negative patients with oropharyngeal cancer (OPC) remain unclear. The present study aimed to characterize cancer stem cells (CSC) of the HPV-negative OPC cell line in terms of chemotherapy resistance. CSCs were isolated through magnetic activated cell sorting using the CSC specific marker aldehyde dehydrogenase 1 antibody, and characterized by sphere formation capacity, immunofluorescence staining, and CSC marker expression. CSC response to cisplatin treatment was evaluated via XTT-assays. Spheres of CSCs of the HPV-negative UTSCC-60A cell line were highly dark holospheres. RNA expression levels of CSC markers OCT4, SOX2, Kruppel-like factor 4 and BMI1 were significantly higher in CSC. CSCs were significantly resistant to cisplatin treatment at various dosages compared with nonCSC. The present study suggested that the proportion of CSCs is very low in the tumor bulk, CSCs are resistant to cisplatin in HPV-negative OPC, which requires further investigation to define their mechanism.

Abstract
OBJECTIVES To compare the Neural Response Telemetry (NRT) results of the cochlear implanted children who showed wave 5 and who could not, in preimplantation ABR. MATERIAL AND METHOD 24 children (11 boys, 13 girls) with bilateral profound sensorineural hearing loss participated in this study. Age of children ranged between 13 and 60 months (mean 30 months). All participated children were implanted with Cochlear® Nucleus brand devices. In preoperative ABR evaluation with click stimulus in 100 dBnHL intensity level, 9 children showed wave V and 15 children did not. We compared intraoperative NRT results of 1st, 6th, 11th, 16th and 22nd electrodes, those were selected from 22 electrodes, of the two groups. RESULTS There was no statistically significant difference between the children who showed wave V and who did not in preoperative ABR, when compared the intraoperative NRT results of 1st, 6th, 11th, 16th and 22nd electrodes (p>0,05). CONCLUSION intraoperative NRT was obtained in all the implanted children with bilateral profound sensorineural hearing loss, even if they received wave V or not in preoperative ABR. There was no difference between any of the parameters of the test results of the two groups. Normal NRT results can be achievable when there is no wave V in preoperative ABR.

Abstract
AIM Meniere's Disease (MD) is a chronic disease that is characterized by intermittent episodes of tinnitus, vertigo, and progressivefluctuating sensorineural hearing loss together with aural fullness. The aim of this study is to evaluate Meniere's disease patients with vestibular test battery as Videonystagmography (VNG), Vestibular Evoked Myogenic Potentials (VEMPs) and Video Head Impulse Test (V-HIT) to assess peripheral and central vestibular systems. METHODS 16 bilateral, 17 unilateral patients suffering from MD (mean age, 40.90 years, range, 23 to 66 years; 20 women and 13 men) comprised the study group, and 39 healthy (mean age, 38.10 years, range from 21 to 60 years; 22 women and 17 men) volunteers formed control group. Evaluation of peripheral and central vestibular systems changes with oculomotor tests, caloric test, C-VEMPs, O-VEMPs, and the evaluation of the vestibular ocular reflex (VOR) using the V-HIT. RESULT Twenty-six ears out of the forty-nine ears that were affected by Meniere's disease were diagnosed as otolith or ampullary dysfunction. As to O-VEMPs testing, N1 and P1 waves could not be obtained from thirty of the forty-nine ears affected by Meniere's disease. As for obtained N1 and P1 waves, prolonged N1 and P1 wave latencies, and reduced amplitude was observed in Meniere's group. P1 and N1 waves were not observed in 5 bilateral and 2 unilateral Meniere's patients (12 ears out of 49 affected ears) in C-VEMPs recordings (23.9%). In Meniere's patients' group, 44.9% of the velocity gain values were obtained in the pathologic borders of v- HIT. In addition to lower velocity gain, higher ratios of asymmetry were obtained from the ears affected with Meniere's disease. CONCLUSION According to these results, it can be concluded that Meniere's disease significantly affects the peripheral vestibular system but the functions of the central vestibular system were not affected.

Abstract
Classical galactosemia is an autosomal recessive inborn error of metabolism caused by biallelic pathogenic variants in the GALT gene. With the benefit of early diagnosis by newborn screening, the acute presentation of galactosemia can be prevented. In this study, we describe the clinical phenotypes, time of diagnosis and GALT genotypes of 76 galactosemia patients from Turkey, where the disease is not yet included in the newborn screening program. The median age at first symptom was 10 days (range 5-20), while the median age at diagnosis was 30 days (range 17-53). Nearly half of the patients (36 patients, 47.4%) were diagnosed later than age 1 month. Fifty-eight individuals were found to have 18 different pathogenic variants in their 116 mutant alleles. In our sample, Q188R variant has the highest frequency with 53%, the other half of the allele frequency of the patients showed 17 different genotypes. Despite presenting with typical clinical manifestations, classical galactosemia patients are diagnosed late in Turkey. Due to the geographical location of our country, different pathogenic GALT variants may be seen in Turkish patients. In the present study, a clear genotype-phenotype correlation could not be established in patients.

Abstract
Background To investigate the behaviour of the inflammatory marker neutrophil-to-lymphocyte ratio (NLR) in the presence of peripheral blood eosinophilia (PBE) in paediatric asthma patients with lower respiratory tract (LRT) infections. Methods This retrospective study enrolled consecutive patients aged ≥5 years who were diagnosed with asthma and whose haemogram values were available. The patients were further subdivided based on the presence or absence of LRT infections and allergies. NLR and C-reactive protein (CRP) were evaluated in relation to the presence or absence of PBE (≥4% eosinophils). Results A total of 991 patients were enrolled in the study. Patients with LRT infections had significantly higher leucocyte and neutrophil counts, a greater NLR and a higher level of CRP compared with patients without LRT infections. Overall, patients with PBE had significantly lower NLRs and CRP regardless of the presence or absence of an LRT infection. The PBE percentage showed moderate inverse correlations with NLR (r = −0.34) and CRP (r = −0.20). Conclusion The presence of PBE was significantly associated with lower NLR and CRP regardless of the presence or absence of an infectious condition.

Abstract
The aim the present study is to evaluate ocular and cervical Vestibular Evoked Myogenic Potentials (VEMPs) of adult individuals with and without tinnitus who have normal hearing. Thirty one patients who have normal hearing, complaining about unilateral or bilateral subjective tinnitus and 30 volunteers who without tinnitus and vestibular complains were enrolled into the present study. Following examination by of Ear Nose Throat (ENT) physician, Tinnitus Disability Questionnaire (TDQ), pure tone audiometry (125-16.000 Hz) speech tests, oVEMP and cVEMP tests were applied to all participants. Fourteen individuals with normal hearing and tinnitus were male (44%) and 17 (56%) were female with an age average of 35.8 ± 10.2.30 years; the control group consisted of 16 males (53%) and 14 females (47%) with an age average of 37.5 ± 12 years. Two individuals of the tinnitus group had bilateral tinnitus and 29 individuals had unilateral tinnitus. A statistically significant difference in individuals without tinnitus and tinnitus must be normal at work between test answers that are not available 125-16000 Hz range Air Conduction (AC) hearing thresholds, speech tests, cVEMP and oVEMP responses. Tinnitus may appear due to many reasons. Vestibular system is one of the conditions that can cause tinnitus. According to the findings obtained from adult individuals with normal hearing, the vestibular system does not cause tinnitus.

Abstract
In this article, we present a case of anastomosing hemangioma that shows cystic change. The tumor was a unilocular cystic lesion consisting of 2 distinct layers. The inner layer was composed of a proliferation of capillary-sized blood vessels resembling red pulp of the spleen. The outer layer was composed of stromal cells that resembled Leydig or steroid cell tumor of the ovary. An immunohistochemical examination confirmed endothelial and stromal characteristics of the layers, respectively. An ultrastructural analysis revealed absence of Reinke crystalloids in the stromal cells. We conclude that anastomosing hemangioma may rarely arise from the ovary as a cystic tumor and may be accompanied with luteinization of stromal cells.

Abstract
Head and neck cancers are the 6th most common cancer type in human malignant tumors and treated with chemoradiotherapy and surgery. Chemotherapy during these treatment modalities leads to damage of intestinal epithelial barriers and results in translocation of intestinal bacteria in bloodstream through invasion in these damaged regions. In this report, we report two cases of hypopharyngeal cancer patients, both of whom received chemotherapy before surgery. The patients demonstrated repeated sepsis before and after surgery, supporting translocation of intestinal bacteria. Proper continuous probiotic use prevented proliferation and intestinal bacterial translocation. Hypothesis of bacterial translocation and prevention by probiotics are discussed.

Abstract
Monocyte to high-density lipoprotein cholesterol ratio (MHR) is a systemic inflammatory marker, and recently, it has been used quite commonly for the assessment of inflammation in cardiovascular disorders. The aim of the present study is to investigate the relevance of MHR as a marker to assess metabolic syndrome (MetS) and MetS severity in clinical practice. A total of 147 patients with MetS who were diagnosed according to National Cholesterol Education Program Adult Treatment Panel III criteria and 134 healthy controls, matched for age and gender, were included in our retrospective study. MHR values were 13.15 ± 6.07 for patients with MetS and 9.74 ± 5.24 for the control group. MHR values of the patients were found to be statistically significantly higher than the control group ( P < .0001). MHR showed a significantly positive correlation with the severity of MetS ( r = .429; P < .0001). When patients with MetS were assessed with MHR in the study population, receiver-operating characteristic curve analysis yielded a cutoff value of 9.36 with a sensitivity of 72%, a specificity of 61%, and a P value <.0001. In logistic regression analyses of MetS with several variables, MHR remained as an independent predictor of MetS (95% CI: 0.721-0.945, P = .005). MHR might be an available and useful inflammatory marker to evaluate patients with MetS and disease severity.

Abstract
BACKGROUND Genetic factors play a large role in cancer, and thus, there is a great desire to understand the effects of different genes in cancer and to also develop gene therapy for better treatments. Therefore, the development of alternative diagnosis and therapy modalities is of utmost importance. The aim of our study was to illuminate the role of ESM1 (endothelial cell-specific molecule-1, also known as Endocan) in proliferation and migration of head and neck cancer, thus helping to pave the way for new treatment modalities and predictive biomarkers. METHODS ESM1 expression was shown with immunofluorescence assay using confocal laser scanning microscope in primary and metastatic head and neck cancer cells. ESM1 expression was knocked down by RNA interference in head and neck cancer cells. Knockdown efficiency was evaluated by quantitative real-time RT-PCR and Western blot. Cell proliferation and migration assays were performed by xCELLigence real-time cell analysis system. RESULTS Immunofluorescence assay showed nuclear localization and high expression of ESM1 in primary and metastatic head and neck cancer cells. ESM1 mRNA and protein levels were significantly decreased in ESM1-knockdown cells compared to control. ESM1-knockdown cells showed reduced proliferation and migration activity when compared to control cells. CONCLUSION These findings suggest that ESM1 has roles on proliferation and migration of head and neck cancer cells.

Abstract
ObjectiveElective circumcision operation for male children can affect their psychological status.AimWe aimed to investigate the traumatic effect of the circumcision procedure and the predictive factors that could contribute to this effect.MethodOne hundred and thirty-four children who admitted to urology and child surgery clinics to perform a circumcision procedure were included in the study. The whole group was divided into two groups including general anesthesia (GA) (n = 71) and local anesthesia (LA) (n = 63) groups. The procedure was performed under general and local anesthesia in the relevant groups. All of the participants filled the Child Depression invenTory (CDI), State (SA), and Trait (TA) Anxiety and Childhood Anxiety Sensitivity index (CASI) before the operation, and the Child Posttraumatic Stress Reaction index (CPSRI) 1 month after the operation.ResultsCDI, CASI and TA scores of the children were similar in both groups, however, SA scores of the LA group were higher than GA group (P < 0.001), and CPSRI scores of the GA group were higher than LA group (P = 0.04). When the other parameters were controlled in regression analysis, only CDI scores predicted CPSRI scores in LA group (P = 0.02), and TA scores predicted CPSRI scores in the GA group (P = 0.03).ConclusionChildren who witness the surgical procedure of the circumcision do not develop serious PTSD symptoms. In contrast, children who experience general anesthesia procedure during circumcision develop more serious PTSD symptoms than children operated with local anesthesia. Trait anxiety and depressive symptom severity may be important in developing PTSD symptoms after circumcision operation.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Introduction Nasal irrigation solutions are widely used following endonasal surgery. These irrigation solutions remove infective debris and crusts, reducing the probability of synechia formation, and accelerate mucosal healing. Objective The aim of the present study was to compare the effects of nasal irrigation solutions with different contents following septoplasty and concha radiofrequency. Methods The present study was a prospective, randomized, controlled simple blind study of 120 patients who underwent septoplasty and bilateral concha radiofrequency. Patients were divided into four groups according to the nasal irrigation solution used: tap water, buffered isotonic saline, saline with xylitol, and hypertonic sea water. Patients were examined on the 7th and 15th postoperative days. A saccharine test was applied to determine mucociliary activity preoperatively and on the 7th and 15th postoperative days. Patients were asked about drying and obstruction using a 10 cm visual analog scale. In addition, patients were examined to determine the crusting score. Results There was no significant difference found in the preoperative and 7th and 15th postoperative days’ mucociliary clearance times among the four groups. The crusting score was found to be significantly lower in the hypertonic sea water group (p < 0.001). Drying and obstruction on the 7th and 15th postoperative days were found to be significantly more comfortable in the hypertonic sea water group (p < 0.001). Conclusion Hypertonic sea water is the recommended irrigation solution, as it is associated with less crusting, drying, and obstruction in the nose for the postoperative period following septoplasty and concha radiofrequency.

Abstract
OBJECTIVES Citrullinemia type 1 (CTLN1) is an autosomal recessive genetic disorder caused by mutations in the argininosuccinate synthetase 1 (ASS1) gene, which encodes for the argininosuccinate synthetase enzyme. Here, we report genetic and clinical characterizations of 14 patients with citrullinemia type 1. DESIGN & METHODS The study group consisted of 14 patients (4 females, 10 males) diagnosed with citrullinemia type 1 from three centers in Turkey. Age of onset, clinical presentation, initial citrulline and ammonia levels, family history and molecular genetic analysis were retrospectively evaluated. RESULTS The mean age of the cohort and the mean age at the time of diagnosis were 48.3±36.5months (min: 12days, max: 10years) and 11.6±26.2months (min: 3days, max: 8years), respectively. In four patients, a homozygous p.Gly390Arg pathogenic variant was detected. All patients homozygous for p.Gly390Arg were diagnosed during the newborn period with the clinical presentation of classical citrullinemia. In each two patients, homozygous p.Arg86His, c.773+49C>T and p.Gly362Val pathogenic variants were detected. Clinical presentation was compatible with the mild form of the disease in patients homozygous for c.773+49C>T and for Gly362Val. Novel compound heterozygous genotypes (p.Ala164Pro/p.Gly390Arg; p.Leu290Pro/p.Gly390Arg; p.Thr389Pro/p.Gly390Arg) were identified in five patients. Of these, three siblings with CTLN1 were diagnosed with the compound heterozygous genotype p.Ala164Pro/p.Gly390Arg at the age of 4days, 5days and 2years, respectively. The other two patients with novel compound heterozygous genotypes (p.Leu290Pro/p.Gly390Arg; p.Thr389Pro/p.Gly390Arg) were identified in the first month of life as neonatal onset form and were born to non-consanguineous parents. CONCLUSION In our study, consistent with the literature, a correlation was found between homozygous p.Gly390Arg mutation and the classic neonatal onset form. Mild citrullinemia was detected in patients with c.773+49C>T or p.Gly362Val pathogenic variants. This study adds to our understanding of the molecular genetic background of patients with CTLN1, and allows to infer on the correlation between the genotype and phenotype of the disease.

Abstract
Purpose: The purpose of this study was to evaluate Interaural Attenuation (IA) in frequency base in the insert earphones that are used in audiological assessments.
Methods: Thirty healthy subjects between 18-65 years of age (14 female and 16 male) participated in our study. Otoscopic examination was performed on all participants. Audiological evaluations were performed using the Interacoustics AC40 clinical audiometer and ER-3A insert earphones. IA value was calculated by subtracting good ear bone conduction hearing thresholds of the worst airway hearing threshold.
Results: In our measuring for 0.125-8.0 kHz frequency were performed in our audiometry device separately for each frequency. IA amount in the results we found in 1000 Hz and below frequencies about 75-110 dB range avarage is 89±5dB, in above 1000 Hz frequencies in 50-95 dB range and avarage it is changed to 69±5dB.
Conclusion: According to the obtained findings the quantity of melting in the transition between the ears are increasing with the insert earphones. The insert earphone should be beside supraaural earphone that is routinely used in clinics. Difficult masking applications due to the increase in the value of IA can be easily done with insert earphones.

Abstract
PURPOSE Recent studies have shown that cancer stem cells are resistant to chemotherapy. The aim of this study was to compare RIF1 gene expression in head and neck, pancreatic cancer and glioma cell lines and the cancer stem cells isolated from these cell lines. METHODS UT-SCC-74 from Turku University and UT-SCC-74B primary tumor metastasis and neck cancer cell lines, YKG-1 glioma cancer cell line from RIKEN, pancreatic cancer cell lines and ASPC-1 cells from ATCC were grown in cell culture. To isolate cancer stem cells, ALDH-1 for UT-SCC-74 and UT-SCC-74B cell line, CD-133 for YKG-1 cell line and CD-24 for ASPC-1 cell line, were used as markers of cancer stem cells. RNA isolation was performed for both cancer lines and cancer stem cells. RNAs were converted to cDNA. RIF1 gene expression was performed by qRT-PCR analysis. RIF1 gene expression was compared with cancer cell lines and cancer stem cells isolated from these cell lines. The possible effect of RIF1 gene was evaluated. RESULTS In the pancreatic cells, RIF1 gene expression in the stem cell-positive cell line was 256 time that seen in the stem cell-negative cell line. CONCLUSION Considering the importance of RIF1 in NHEJ and of NHEJ in pancreatic cancer, RIF1 may be one of the genes that plays an important role in the diagnoses and therapeutic treatment of pancreatic cancer. The results of head and neck and brain cancers are inconclusive and further studies are required to elucidate the connection between RIF1 gene and these other types of cancers.

Conclusion: Considering the importance of RIF1 in NHEJ and of NHEJ in pancreatic cancer, RIF1 may be one of the genes that plays an important role in the diagnoses and therapeutic treatment of pancreatic cancer. The results of head and neck and brain cancers are inconclusive and further studies are required to elucidate the connection between RIF1 gene and these other types of cancers.

Abstract
PURPOSE The purpose of this study was to evaluate Interaural Attenuation (IA) in frequency base in the insert earphones that are used in audiological assessments. METHODS Thirty healthy subjects between 18-65 years of age (14 female and 16 male) participated in our study. Otoscopic examination was performed on all participants. Audiological evaluations were performed using the Interacoustics AC40 clinical audiometer and ER-3A insert earphones. IA value was calculated by subtracting good ear bone conduction hearing thresholds of the worst airway hearing threshold. RESULTS In our measuring for 0.125-8.0 kHz frequency were performed in our audiometry device separately for each frequency. IA amount in the results we found in 1000 Hz and below frequencies about 75-110 dB range avarage is 89±5dB, in above 1000 Hz frequencies in 50-95 dB range and avarage it is changed to 69±5dB. CONCLUSION According to the obtained findings the quantity of melting in the transition between the ears are increasing with the insert earphones. The insert earphone should be beside supraaural earphone that is routinely used in clinics. Difficult masking applications due to the increase in the value of IA can be easily done with insert earphones.

Abstract
Peroxisomal disorders are a group of genetically heterogeneous metabolic diseases related to dysfunction of peroxisomes. Dysmorphic features, neurological abnormalities, and hepatic dysfunction can be presenting signs of peroxisomal disorders. Here we presented dysmorphic facial features and other clinical characteristics in two patients with PEX1 gene mutation. Follow-up periods were 3.5 years and 1 year in the patients. Case I was one-year-old girl that presented with neurodevelopmental delay, hepatomegaly, bilateral hearing loss, and visual problems. Ophthalmologic examination suggested septooptic dysplasia. Cranial magnetic resonance imaging (MRI) showed nonspecific gliosis at subcortical and periventricular deep white matter. Case II was 2.5-year-old girl referred for investigation of global developmental delay and elevated liver enzymes. Ophthalmologic examination findings were consistent with bilateral nystagmus and retinitis pigmentosa. Cranial MRI was normal. Dysmorphic facial features including broad nasal root, low set ears, downward slanting eyes, downward slanting eyebrows, and epichantal folds were common findings in two patients. Molecular genetic analysis indicated homozygous novel IVS1-2A>G mutation in Case I and homozygous p.G843D (c.2528G>A) mutation in Case II in the PEX1 gene. Clinical findings and developmental prognosis vary in PEX1 gene mutation. Kabuki-like phenotype associated with liver pathology may indicate Zellweger spectrum disorders (ZSD).

Abstract
Coffin-Siris syndrome (CSS) (MIM 135900) is characterized by developmental delay, severe speech impairment, distinctive facial features, hypertrichosis, aplasia or hypoplasia of the distal phalanx or nail of the fifth digit and agenesis of the corpus callosum. Recently, it was shown that mutations in the ARID1B gene are the main cause of CSS, accounting for 76% of identified mutations. Here, we report a 15 year-old female patient who was admitted to our clinic with seizures, speech problems, dysmorphic features, bilaterally big, large thumb, café-au-lait (CAL) spots, obesity and hyperinsulinism. First, the patient was thought to have an association of neurofibromatosis and Rubinstein Taybi syndrome. Because of the large size of the NF1 gene for neurofibromatosis and CREBBP gene for Rubinstein Taybi syndrome, whole exome sequence analysis (WES) was conducted and a novel ARID1B mutation was identified. The proband WES test identified a novel heterozygous frameshift mutation c.3394_3395insTA in exon 13 of ARID1B (NM_017519.2) predicting a premature stop codon p.(Tyr1132Leufs*67). Sanger sequencing confirmed the heterozygous c.3394_3395insTA mutation in the proband and that it was not present in her parents indicating de novo mutation. Further investigation and new cases will help to understand this phenomenon better.

Abstract
Malnutrition is a common consequence of cancer in children, but the most effective methods of nutrition intervention are under debate. We aimed to evaluate the nutritional status of children diagnosed with cancer, and to investigate the effect of oral nutritional supplements on anthropometric measurements, biochemical parameters, and outcome. A randomized clinical study of 45 newly diagnosed cancer patients was performed. Anthropometric and biochemical data and related factors were assessed at 0, 3, and 6 months after diagnosis. On initial anthropometric assessment, prevalence of malnutrition by weight or height was found to be lower as compared with body mass index (BMI), or weight for height (WFH), or arm anthropometry. Twenty-six of the patients (55%) received oral nutritional supplement. During the second 3 months after diagnosis, there was a statistically significant decrease in number of the patients with WFH <90th percentile and BMI <5th percentile (P = .003 and P = .04, respectively). Infectious complications occurred more frequently in malnourished patients during first 3 months, and survival of children who were malnourished at the 6th month was significantly lower than that of well-nourished children (P = .003). On laboratory assessment, serum prealbumin levels of the all subjects were below normal ranges, but no relation was found for serum prealbumin or albumin levels in patients who were malnourished or not at diagnosis. Nutritional intervention is necessary to promote normal development and increase functional status as a child receives intensive treatment. Protein- and energy-dense oral nutritional supplements are effective for preventing weight loss in malnourished children.

Abstract
PURPOSE Optimal duration of adjuvant trastuzumab therapy in early-stage HER2-positive, lymph node-negative breast cancer is unknown. To establish this, we compared 1-year and 9-week trastuzumab regimens in HER2-positive, lymph node-negative early-stage breast cancer patients. METHODS We retrospectively analyzed 4374 breast cancer patients. There were 181 early-stage, lymph node-negative breast cancer patients who were treated with adjuvant trastuzumab for either 9-week or 1-year schedule. A total of 101 patients received trastuzumab for 9 weeks and the remaining 80 patients received this adjuvant therapy for 1 year. Disease free survival (DFS) and overall survival (OS) rates of both groups were calculated. RESULTS There was no difference between groups according to OS. Five-year OS rates were 95.5% in the 9-week group and 93.3% in the 1-year group (p=0.78). DFS was affected by age, having tamoxifen therapy and disease stage. Nine-week trastuzumab group was superior to 1-year group and 5-year DFS rates were 91% in 9-week group and 81.2% in 1-year group (p=0.02). However, the 1-year group had more stage II patients than the 9-week group. We did not find any difference between groups regarding developing congestive heart failure. CONCLUSION It appeared that 9-week trastuzumab treatment was not inferior to 1-year trastuzumab treatment in early-stage, lymph node-negative breast cancer patients.
