Abstract
AIM To evaluate the treatment results, prognostic parameters, and treatment-related toxicity in patients with Ewing sarcoma (ES)/primitive neuroectodermal tumor (PNET) of the chest wall who underwent surgery, chemotherapy, and radiotherapy (RT) in a tertiary referral center. METHODS The data of 24 patients under 18 years of age with a histologic diagnosis of ES/PNET in the chest wall that received RT in our department between February 2003 and July 2020 were retrospectively evaluated. RT was applied to the primary site±whole involved chest wall and to the whole lung in patients with lung metastasis. RESULTS The median age was 8.5 years (range: 1.5 to 17 y), 15 (63%) patients were female and 9 were male (37%). The tumor localization was extrathoracic in 18 (75%) and intrathoracic in 6 (25%) patients. Mediastinal lymph node and distant metastasis (DM) was present in 5 (21%) and 4 (16%) cases at diagnosis, respectively. The median follow-up after RT was 47 months (range: 11 to 162 mo). The 2-year and 5-year overall survival, event-free survival, local recurrence-free survival, and pleural recurrence-free survival were 83% and 48%, 48% and 42%, 74% and 48%, and 61% and 52%, respectively. The overall local control rate was 83% and the pleural control rate was 67%. RT was well tolerated, with 1 case of grade 3 acute dermatitis and 1 case of grade 3 subacute radiation pneumonitis. Late toxicity was observed in 3 (13%) cases. CONCLUSION Long-term survival can be achieved with extended-field RT even in patients with ES/PNET of the chest wall with DM. The low toxicity rates allow us to draw the conclusion that RT with modern techniques is an effective and safe treatment modality for these patients.

Abstract
BACKGROUND Ganglioneuromas (GNs) are rare benign peripheral neuroblastic tumors (PNTs). We shared our institutional experience with childhood GNs. METHODS Records of the children with PNTs between January 1995 and December 2021 were reviewed, and cases with histopathological diagnoses of GN were identified. Clinical, laboratory, radiological, and histopathological findings, image-defined risk factors (IDRFs), procedures, and overall outcomes were recorded. RESULTS Of 668 cases with PNTs, 70 (10.4%) had GNs. The median age was 7.4 years (range, 2.6-15.7 years) (girls/boys, 41/29). Common presenting complaints were abdominal pain and cough; 33/70 cases (47.1%) were diagnosed incidentally. Primary tumors were in the abdomen in 41/70, the thorax in 25/70, the neck in 3 cases, and the pelvis in one. The median tumor size was 6.5 cm (range, 1.4-17). Fifty cases (71.4%) were staged as INRG-L1; 20 cases with IDRFs (15 single, five >1) were staged as INRG-L2. Complete and partial tumor resections were performed in 58/70 and 6/70 cases, while 6 had no resection. The overall complication rate was 17.1% (11/64). At a median follow-up of 9 years, five were lost to follow-up; 65 were alive. One patient with gross residue underwent total resection due to progression 13 years after the surgery, and one in the unresected group was lost to follow-up. Ten other cases without a complete resection experienced no tumor progression. CONCLUSIONS Ganglioneuromas are benign PNTs, and most are free of IDRFs. Even without complete resection, long-term outcomes are excellent. Guidelines should be devised considering the high surgical complication rates and benign course of GNs. LEVEL OF EVIDENCE Case series, IV.

Abstract
OBJECTIVE This study aimed to determine whether there is a relationship between changes in blood estrogen levels and hearing threshold levels in women undergoing in vitro fertilization (IVF). PATIENTS AND METHODS Sixty patients with normal otoscopic examination findings and scheduled for IVF treatment were included in the study. All patients underwent pure tone audiometry, tympanogram tests, and otoacoustic emission measurements (TEOAE) during IVF treatment, and estrogen levels were measured simultaneously. The patients were divided into three groups based on estrogen levels during IVF. The patients' audiological test results at the beginning and end of treatment (the 12th day) were compared between the groups. RESULTS There was an increase in hearing levels on the 12th day of treatment compared to the beginning of treatment in all the study groups. This increase was significant between Group 1 and Group 2 and between Group 1 and Group 3 (p<0.05). The best hearing in audiometry was determined in the patients in Group 2. While a significant increase was observed in TEOAE (otoacoustic emission) measurements in Groups 1 and 2, a significant decrease was determined in Group 3 (p<0.05). Middle ear pressure and compliance measurements on the tympanogram tests were significantly lower in Group 3 compared to Groups 1 and 2 (p<0.05). CONCLUSIONS During IVF treatment, as the estrogen level increases, it causes an increase in the level of hearing, but this increase does not continue after specific doses.

Abstract
PURPOSE/OBJECTIVE(S) The American Joint Committee on Cancer (AJCC) anatomic stage groups have arguably been the most powerful method in predicting breast cancer outcomes. In the present study, we aimed to determine the differences between anatomical stage and clinical prognostic stage groups, which were obtained by adding biological markers such as histologic tumor grade, estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 status to patients diagnosed with breast cancer, the rate of change in stage, and the effect of stage change on survival. MATERIALS/METHODS The study protocol was sent to all radiation oncology centers in Türkiye. Four centers enrolled their patients to the study. A total of 1470 stage I-III breast cancer patients with complete information on biological markers (histologic tumor grade, hormone receptor, and c-erb B2 receptor status), haven't been treated with neoadjuvant therapy were included to the study and evaluated retrospectively. The 8th edition of AJCC consolidated biological markers in to clinical prognostic stage groups. Kaplan-Meier curves were used to estimate survival. The log-rank test was used to compare the difference between groups. The Cox proportional-hazards regression model was used to determine the association between anatomic-prognostic stage, disease-free survival (DFS), and overall survival (OS). RESULTS The median follow-up time was 82 (6-237) months. Median age of the patients was 52 years (20-88) and 865 cases (58.8%) were in the postmenopausal period. The axillary lymph node status was negative (N0) in 765 patients (52.1%). Tumor grade was grade I in 200 patients (13.6%), grade II in 812 patients (55.2%) and grade III in 452 patients (30.7%). Estrogen receptor status was positive in 1247 patients (84.8%), PR status was positive in 1178 patients and Her2-neu status was positive in 207 patients (14.1%). A stage change has been identified in a total of 777 patients (52.9%). Compared with the anatomic stage groups, application of the clinical prognostic stage groups assigned 46.4% cases lower and 6.5% cases higher stage. Five- and ten-year OS and DFS rates of the patients are 73.7%, 44.3% and 91.9%, 86.3% respectively. Age (p<0.001), tumor grade (p<0.001), ER status (p<0.001), PR status (p<0.001), cerbB2 receptor status (p = 0.025) were found to be statistically significant variables in multivariable analysis for OS. For DFS, multivariable analysis showed that age (p = 0.027), tumor grade (p = 0.005), anatomical stage (p<0.001) and assigned to higher stage (p = .001) were statistically significant variables. CONCLUSION Hormone receptors and c-erb B2 receptor status are independent variables which impact OS and DFS in our patient group which is mostly consisted of early-stage cases according to anatomical stage. In prognostic staging, upstaging stands out as an independent prognostic factor for DFS. The 8th edition of AJCC prognostic stage groups determines the prognosis much better in our patient cohort.

Abstract
PURPOSE/OBJECTIVE(S) The deep inspiration breath-hold (DIBH) approach has been thoroughly researched with the aim of reducing radiation exposures to normal tissues in breast cancer patients. Although heart and lung toxicity are widely addressed in many literature, radiation-associated liver toxicity and dose constraints for the right coronary artery (RCA) are not well studied in relation to breast radiotherapy. Additionally, very few studies have investigated the relationship between doses to cardiac substructures. This study aimed to determine the effect of the DIBH technique on the right coronary artery (RCA) region, cardiac substructures, and liver dose in right breast cancer irradiation. MATERIALS/METHODS Between January 2022 and December 2022, thirty-five right breast cancer patients who previously received breast-surgery underwent computed tomography (CT) simulation with both free-breathing (FB) and DIBH techniques. Patients were contoured by a radiation oncologist on the scans using the Treatment Planning System. For cardiac substructures, reference atlas contours were used for accurate delineation and to reduce inter-observer variation. Each patient underwent two treatment plans for both the DIBH and FB datasets. The plan comprised the FB and DIBH techniques, and the doses to the cardiac substructures, ipsilateral lung, RCA region, and liver were compared using a two-tailed paired t-test. Radiotherapy was delivered with a Linac with the prescription dose of 50 Gy in 25 fractions. RESULTS For both FB and DIBH irradiation groups, the mean radiation doses to the ipsilateral lung, heart, and RCA region in patients with FB and DIBH techniques were; 14.67 Gy, 2.33 Gy, 4.88 Gy and 12.05 Gy, 1.34 Gy and 3.29 Gy respectively. The mean radiation doses to the cardiac substructures; for the left ventricle, right ventricle, left atrium, and right atrium for the FB were 1.08 Gy, 1.79 Gy, 4.11 Gy, and for DIBH, 0.49 Gy, 1.49 Gy, 0.95 Gy, and 2.61 Gy, respectively. For the DIBH group, the liver maximum dose (p<0.01), right lung mean dose (p = 0.001), heart maximum dose (p = 0.009), RCA mean dose (p = 0.020), RCA maximum dose (p = 0.008), RCA V5 dose (p = 0.035), right atrium maximum dose (p = 0.009) and right ventricle mean dose (p = 0.040) were significantly lower than in patients treated in the non-gated group. CONCLUSION DIBH resulted in considerable displacement of the liver away from the high-dose target region, such that the volume of liver in the high-dose region was reduced. Additionally, the use of the DIBH technique in right breast cancer irradiation effectively reduces the radiation doses to the cardiac substructures, such as the left ventricle, right ventricle, left atrium, right atrium, RCA region, and lungs. DIBH could lead to substantial sparing of these structures with the right breast cancer radiotherapy. Future prospective studies are required to determine whether improvements to dose-distribution will translate into improved toxicity outcomes.

Abstract
The purpose of the study was to review the clinical and pathologic characteristics and treatment results of children with precursor B-cell lymphoblastic lymphoma. Of 530 children diagnosed with non-Hodgkin lymphomas between 2000 and 2021, 39 (7.4%) were identified as having precursor B-cell lymphoblastic lymphoma. Clinical characteristics, pathologic, radiologic, laboratory data, treatments, responses, and overall outcomes were recorded from hospital files and analyzed. The median age of 39 patients (males/females, 23/16) was 8.3 years (range 1.3 to 16.1). The most common sites of involvement were the lymph nodes. At a median follow-up of 55.8 months, 14 patients (35%) had a recurrence of disease (11 stage IV, 3 stage III); 4 were in complete remission with salvage therapies, 9 died of progressive disease and one died due to febrile neutropenia. Five-year event-free survival and overall survival rates were 65.4% and 78.3% for all cases, respectively. Survival rates were higher in patients with a complete remission at the end of induction therapies. The survival rates were lower in our study compared with other studies, which could be explained by the high relapse rate and higher incidence of advanced-stage disease due to bone marrow involvement. We demonstrated a prognostic impact of treatment response at the end of the induction phase. Cases with a disease relapse have poor prognosis.

Abstract
PURPOSE Non-functioning pituitary neuroendocrine tumors are challengingly diagnosed tumors in the clinic. Transsphenoidal surgery remains the first-line treatment. Despite the development of state-of-the-art techniques, no drug therapy is currently approved for the treatment. There are also no randomized controlled trials comparing therapeutic strategies or drug therapy for the management after surgery. Therefore, novel therapeutic interventions for the therapeutically challenging NF-PitNETs are urgently needed. METHODS We integrated epigenome and transcriptome data (both coding and non-coding) that elucidate disease-specific signatures, in addition to biological and pharmacological data, to utilize rational pathway and drug prioritization in NF-PitNETs. We constructed an epigenome- and transcriptome-based PPI network and proposed hub genes. The signature-based drug repositioning based on the integration of multi-omics data was performed. RESULTS The construction of a disease-specific network based on three different biological levels revealed DCC, DLG5, ETS2, FOXO1, HBP1, HMGA2, PCGF3, PSME4, RBPMS, RREB1, SMAD1, SOCS1, SOX2, YAP1, ZFHX3 as hub proteins. Signature-based drug repositioning using hub proteins yielded repositioned drug candidates that were confirmed in silico via molecular docking. As a result of molecular docking simulations, palbociclib, linifanib, trametinib, eplerenone, niguldipine, and zuclopenthixol showed higher binding affinities with hub genes compared to their inhibitors and were proposed as potential repositioned therapeutics for the management of NF-PitNETs. CONCLUSION The proposed systems' biomedicine-oriented multi-omics data integration for drug repurposing to provide promising results for the construction of effective clinical therapeutics. To the best of our knowledge, this is the first study reporting epigenome- and transcriptome-based drug repositioning for NF-PitNETs using in silico confirmations.

Abstract
OBJECTIVE Mild traumatic brain injury (mTBI) cases with a normal CT scanning account for the vast majority of all TBI patients. The aim of this study was to investigate the course of serum Phosphorylated Neurofilament Heavy Chain (pNF-H) levels in the first six hours after trauma in rats in experimental mTBI. MATERIALS AND METHODS In this experimental animal study, 32 female Sprague-Dawley rats were enrolled equally (n=8) into 3 experimental groups and 1 control group. In experimental groups, animals were exposed to a mTBI with a free fall of 50-gram metal disc from a height of 80 cm. We compared serum pNF-H levels at the 2nd, 4th, and 6th hours after traumatic brain injury in the experimental groups with the control group. RESULTS Serum pNF-H levels at the 2nd and 4th hours after traumatic brain injury were statistically significantly higher than the control group. Serum pNF-H levels gradually decreased at the 4th and 6th hours compared to the 2nd hour and decreased to a similar level to the control group at the 6th hour after injury. CONCLUSIONS A high serum pNF-H value, could be used in the diagnosis and management of mTBI patients.

Abstract
Abstract
Study question
To examine the utility of a range of expanded screening panels for oocyte donors.
Summary answer
Expanded carrier screening with NGS data identified that 86% of gamete donors were carriers of at least one condition while 302 genes were tested.
What is known already
The level of genetic testing for oocyte donors is not regulated in most countries. The use of expanded carrier screening is recommended more widely. If the egg donor is a carrier, there is a 50% chance that the offspring will also be carriers. Expanded carrier screening is performed to determine the potential effects of positive carrier status, which guarantees safety for future pregnancy. From practical experience, more genes are tested for a donor, more potential mutations are detected.
Study design, size, duration
A cohort of 92 potential oocyte donor applicants aged 18-30 years old, who were qualified for oocyte donation after full screening, tested negative on an initial cystic fibrosis carrier test for 11 most common CFTR mutations (PCR panel), was further screened with expanded commercial carrier testing panel (302 genes) using next-generation sequencing (NGS) data.
Participants/materials, setting, methods
A cohort of 92 potential oocyte donor applicants aged 18-30 years old, who tested negative on an initial cystic fibrosis carrier test for 11 most common CFTR mutations (PCR panel), was further screened with expanded commercial carrier testing panel (302 genes) using next-generation sequencing (NGS) data.
Main results and the role of chance
Genotyping results for all donors were analyzed; 38% (35/92) of donors were identified as carriers for one condition, 34% (31/92)- for two conditions, 7% (6/92)- for three conditions and 7% (6/92)- for four conditions, including cystic fibrosis. Among the most prevalent conditions in our study were: Hemochromatosis: Type 1: HFE Related- 22%, Cystic Fibrosis: CFTR-related conditions 11%, Biotinidase deficiency– 7,6%, 21-Hydroxilase-Deficient Congenital Nonclassical Adrenal Hyperplasia- 6,5%, Krabbe disease – 6,5%, Usher syndrome: USH2A-related conditions – 6,5%, Nonsyndromic deafness: GJB2- related conditions- 5,4% and Smith-Lemli-Opitz syndrome (5,4%).
Limitations, reasons for caution
Each donor was consented for genetic testing
Wider implications of the findings
This study shows a need to provide the explicit requirement for oocyte donor genetic testing and guidelines to satisfy quality and safety and not reduce the number of donors carries of mutations, but to implement a practice of genetic matching.

Abstract
Abstract
We should describe war as an attack maneuver by two countries or organizations against each other in line with their mutual interests when giving it significance. What is going on in Ukraine is more than a war; it is people's effort to defend their future, past from this genocide attacks which done by Russian Federation.
Russian Federation’s attacks not only damage all healthcare and scientific institutions but also make any future advancement in healthcare impossible. Millions of Ukrainians and foreigners residing, working, and living in the country were uprooted and forced to flee. While the strikes rendered general healthcare and fertility services inoperable, they also made protecting and maintaining all stored gametes and embryos challenging. Many infertility patients and thousands of IVF couples who have undergone oncofertility cryopreservation have been put at risk due to these attacks.
While what happened in Ukraine affects thousands of infertility patients worldwide, the horrific situations faced by hundreds of IVF specialists, embryologists, nurses, and other allied healthcare workers, along with the losses they have suffered and the uncertainty of their future, reveal that the situation is far more than a war and that it is a genocide situation that no one who values life should accept.
Embryologists were trying to freeze embryos and gametes at different developmental stages of dozens of patients in their incubators on February 24, when the Russian Federation’s attacks started, ignoring the vital risks, again, on the day of the war beginning, and IVF specialists who performed egg collection and embryo transfer procedures for all patients who were in that day before, as well as all the other healthcare workers who took part in this process — they all showed how professionally and willingly the IVF service in Ukraine is provided. When the attacks became more intense in the days ahead, hundreds of Ukrainian embryologists risked their lives and the lives of their families to transport frozen samples to secure regions within the country and even beyond, sending a powerful message to the entire world.
Expert embryologists moved all frozen components to secure locations, adhering to all safety regulations and regularly monitoring temperature and liquid nitrogen levels. It is impossible to say that this transportation method is not at risk from attacks. The transfer process was carried out fully to protect patients, with individual decisions made without acquiring patient consent forms or essential approvals due to the urgency of the decisions made from the moment the attacks had begun.
The samples obtained abroad, on the other hand, were transported to European countries after all of the necessary legal registrations and procedures were completed at customs, following long and exhausting land journeys. Storage tanks that can be transferred within Ukraine were moved to western cities and secured in clinics with medical licenses. Samples were also secured in clinics with medical licenses outside of Ukraine, and all essential legal documents and regulations were completed.
While over 70,000 frozen embryos have been carried abroad, over 10,000 frozen eggs have been transported for egg banking. Thousands of testicular tissue samples and hundreds of ovarian tissue samples were also transported. In Ukraine, thousands of frozen embryo and sperm samples are now successfully preserved. So far, no embryo harm or difficulties with liquid nitrogen delivery have been recorded. However, if Russian Federation’s attacks continue, the difficulties will inevitably worsen, putting hundreds of frozen patient samples in danger.
Hundreds of embryologists, IVF specialists, nurses, and paramedics were also laid off, and many were forced to flee the country. The Russian Federation’s attacks on the Ukrainian people have put human lives and the future prospects of countless infertility patients in jeopardy.

Abstract
Aberrations of the STK4 gene in humans result in an autosomal recessively inherited primary immunodeficiency. We identified three patients with STK4 deficiency who had presented to our hospital and reviewed their biopsy samples with the goal of detailing the characteristics of STK4 deficiency from a pathology perspective. Case 1 was a 20-year-old male who presented with cervical and supraclavicular lymphadenopathy which showed plasmacytic hyperplasia and a concurrent bronchial mass, with AA amyloidosis and EBV-associated "polymorphic lymphoproliferative disorder (LPD) resembling polymorphic post-transplant LPD." The second case was an 8-year-old girl with abdominal lymphadenopathy; biopsy revealed a complex lymphoproliferation which consisted of EBV-associated "polymorphic LPD resembling polymorphic post-transplant LPD," plasmacytic hyperplasia, granulomatous reaction, and a CD4- and PD-1-positive clonal T cell proliferation. The third was a 15-year-old girl with a laryngeal mass, representing a high-grade B cell lymphoma with prominent plasmacytic differentiation. Our cases emphasize the complex and challenging histopathology of lymphoid proliferations in patients with STK4 deficiency.

Abstract
Purpose Intracranial germ cell tumors (ICGCTs) comprise approximately 0.4%-3% of all brain tumors. In this study, we aim to evaluate clinical characteristics, treatment and outcomes of patients with ICGCT. Patients and Methods All patients with ICGCT diagnosed in Hacettepe University's Pediatric Oncology Department between January 1980 and January 2016 were evaluated, retrospectively. Results We identified 52 patients (male/female: 2.46) diagnosed with ICGT. Median age was 140 months. The median duration of symptoms was 3 months. Patients with endocrine symptoms were diagnosed later than others (P = 0.028). The primary site was pineal region in 20 patients, nonpineal region in 32 which included six bifocal involvements. Pineal location was more common in boys than girls (P = 0.02). Histopathological diagnosis was germinoma in 28 patients, nongerminomatous malignant germ cell tumors in 14 and immature teratoma in 4. The mean age for germinoma was higher than that of nongerminomatous tumors (P = 0.032). Patients treated with surgery and radiotherapy and chemotherapy. Median follow-up time was 52.5 months. Thirty-six patients were alive for 12-228 months. Relapsed/progressive disease was observed in 11 patients. Nongerminomatous tumors more frequently showed relapse/progression than germinoma (P = 0.06). Five-year overall and event-free survival rates for the whole group were 72.6% and 57.2%, respectively. Overall and event-free survival rates for germinoma were better than malignant nongerminomatous tumors. Conclusion Although the ratio of ICGCTs to central nervous system tumors in our series was similar to western countries, some clinical features such as tumor location were similar to cases from East Asian countries. Although similar protocols were used survival rates lower than developed western and eastern developed countries.

Abstract
e24088 Background: Palliative care is patient and family-centered care provided to optimize the quality of life in serious illness, and is an essential health service under Universal Health Coverage. Given the burden of cancer and other chronic disease diseases along with demographic changes, the need for palliative care is growing in Turkey. This study aimed to review of the available scientific literature on palliative cancer care needs, models and outcomes Turkey. Methods: A comprehensive literature review was conducted with English and Turkish keywords in PubMed, Scopus, Embase, ScienceDirect, Web of Science, Google Scholar, The Turkish Academic Network and Information Centre databases, Turkish Ministry of Health documents, Turkish Council of Higher Education’s doctoral thesis, and renowned national and international palliative care as well as cancer conferences 01/ 2000 to 07/ 2020. Results: Out of 27489 papers identified, 320 met the criteria for inclusion. The main focus of these studies was; historical development in palliative care, legislative regulation, professional training, use of opioids, symptom management, care for patients, palliative care centers, public awareness, psychosocial support, and end of life ethics. The majority of this literature used descriptive design, although a few case-control, cohort, and randomized control trials were also found. Our analysis showed that the development of PC in Turkey can be divided into three period. The first (early initiatives, before 2000), the second (dissemination phase, 2000-2010), and the third stage (government & societial engagement, after 2010). Several studies also analyzed the barriers such as low public & professional awareness, disconnection from cancer care, the opioidfobia and the lack of trained palliative care providers. The lack of integration of palliative care to cancer care is a major challenge for palliative care implementation. Conclusions: This review presents the evidence of the significant progress in PC during the last 20 years and the opportunities for further progress. Bringing research into practice is needed for shaping the integration of palliative care to cancer care in Turkey. The stakeholders and policy makers should not neglect the need for PC under the current pressure of COVID-19 pandemic on health and economy.

Abstract
e14042 Background: Optic gliomas are the most common tumors of the optic pathway, comprising about 1% of all intracranial tumours. Here we present the clinical characteristics and the outcome of patients with optic glioma at our institution. Methods: Seventy two patients diagnosed and followed up at a pediatric cancer center in Ankara, Turkey between January 1, 2008 and December 31, 2020 were included in this analysis. The clinical features and outcome of patients were recorded from patient files and hospital information system retrospectively. Results: The median age at the time of diagnosis was 3.5 years (4-157 months), the female/male ratio was 1.3. Fourteen children (19%) were asymptomatic and tumors were detected with routine surveillance, and 58 (81%) had symptoms (the most common being proptosis in 16 patients (22%)). The most common site of optic glioma was the intraorbital region (31%). Fourty patients (55%) had neurofibromatosis type 1 (NF-1). Five patients had histopathological diagnoses; 3 pilomyxoid astrocytoma, 2 pilocytic astrocytoma. Children were treated if they had tumor progression on MRI and/or worsening visual acuity. Twenty seven (38%) children were observed without any therapy, 6 patients (8%) received radiation and chemotherapy, 4 patients (5%) received radiation only, and 35 patients (49%) received chemotherapy only. Treatment regimens for the 41 children who received chemotherapy included carboplatin/etoposide (17), cisplatin/etoposide (18), carboplatin/vincristine (5), and temozolomide (1). The 5-year progression-free survival (PFS) and overall survival (OS) were 64% and 90%, respectively with a 31 month median follow-up. The 5 year PFS was significantly lower in patients with optic tract-hypothalamic-chiasmatic involvement (34%) than orbital involvement (83%) (p=0.013). Five year PFS was significantly higher in patients with NF-1 (80%) than patients without NF-1(46%) (p=0.027) and significantly lower in patients diagnosed at <3 years old (37%) (p=0.05). Five patients died of disease, and one died of infection after chemotherapy. Two patients treated with platin (1 carboplatin, 1 cisplatin) developed ototoxicity. One patient with NF-1 developed Moya-Moya disease. Two patients developed multiple pituitary hormone deficiencies and one patient developed precocious puberty during follow-up. No secondary malignancy was observed. Conclusions: The management of optic glioma remains challenging. Although the overall survival for children with this disease is excellent, progression of disease is frequent, particularly in those children without NF-1, younger children and non-orbital tumors. This study from Turkey showed comparable results with high-income countries. Further studies with longer follow-up periods are needed to find appropriate treatment strategies.

Abstract
e22518 Background: Rhabdomyosarcoma is a rare tumor in children and adolescents, presenting 3% to 4% of all pediatric cancers. The female genital tract is considered as a favorable site of childhood RMS. The outcome has improved significantly during the last two decades, attributed to risk stratification and multimodality management of these challenging tumors. Here we present the clinical features and treatment results of girls with genital tract rhabdomyosarcoma to discuss. Methods: Fourteen girls with vaginal and uterine servical rhabdomyosarcoma younger than 18 years of age diagnosed and followed up between the years of 1995 and 2019 were included in this analysis. The clinical features and treatment results of patients were recorded from patient files and hospital information system retrospectively. Results: There were seven cases with vaginal and seven with uterin cervical carcinoma. All patients presented with polypoid masses protruding from the vagina. Median age of patients at diagnosis was 71 months (range 8-200 months). The IRS modified TNM staging was stage I for all the patients. All cases had embryonic type of RMS except one with alveolar type. All patients were treated with surgery and adjuvant chemotherapy, three received radiotherapy additionally. All achieved complete remission. Four patients experienced tumor relapse, 1 patient died with progressive disease. The median follow-up time was 75 months (7-271 months) for 13 patients who were alive with remission. Conclusions: Rhabdomyosarcoma is a rare sarcoma with a higher incidence in children and adolescents. With current treatment strategies, female genital tract rhabdomyosarcomas have a good prognosis. Favorable prognostic factors such as early stage at diagnosis and a favorable histology may contribute to the excellent observed survival. All parties who had involved on the care of these girls must be aware of the high survival with proper treatment to avoid treatment related morbidities and mortalities. Because of the rareness of the disease we wanted to share our experience.

Abstract
A dentin biomodification strategy with selective proanthocyanidin (PAC)-enriched extracts reinforces dentin and dentin-resin interfaces. Enrichment of the extracts according to the degree of polymerization allows exploration of bioactive principles of PACs and structure-activity relationships. This study investigated the sustained dentin matrix biomodification and dentin-resin bioadhesion of 2 fractions consisting exclusively of B-type PAC dimers with or without a single galloyl motif (specifically, DIMERG and DIMERNG) and their precursor material, enriched grape seed extract (e-GSE; Vitis vinifera). The biomodification potential was determined by long-term evaluation of the apparent modulus of elasticity and collagen solubility (hydroxyproline release). Chemical characterization of the dentin matrix was performed by attenuated total reflectance-Fourier-transform infrared spectroscopy. The bioadhesive properties were assessed by a microtensile bond strength test at different time points, and macro-hybrid layers were produced to verify the degree of conversion of the adhesive resin. Fractions consisting of DIMERG, DIMERNG, and their precursor, e-GSE, increased the modulus of elasticity at all time points and reduced collagen degradation. Specimens treated with DIMERNG remained stable throughout 12 mo of storage, whereas a significant drop in the modulus of elasticity was observed for the DIMERG and e-GSE groups at 6 mo. The fractions and precursor did not affect the degree of resin conversion at the hybrid layer. Changes in infrared resonances corresponding to collagen cross-links in the dentin matrix occurred for all treatments. Higher bond strength was observed for dentin treated with e-GSE as compared with DIMERG and DIMERNG; all biointerfaces remained stable after 12 mo. Nongalloylated PACs mediate stable dentin biomodification, which includes protective activity against collagen degradation and reinforcement of the anchoring dentin matrix. Collectively, PACs with a higher degree of oligomerization offer a robust bioadhesion between the hydrophilic dentin matrix and the hydrophobic adhesive.

Abstract
BACKGROUND Aneurysmal bone cyst (ABC) is a benign bone tumor. Curettage and bone grafting is the common treatment. Here, we retrospectively evaluate nine patients treated with denosumab. PROCEDURE Nine patients with ABC, mostly pelvic and vertebral, treated with denosumab were analyzed retrospectively. A 70 mg/m2 denosumab dose was used weekly in the first month, and then monthly. Clinical and radiological responses to treatment were evaluated. RESULTS In all patients, clinical symptoms including pain and limping regressed completely within 3 months. Radiological evaluation revealed changes in lesion size and content. In six patients, overall volume reduction in the range of 18-82% was detected. Decreases in the size and number of cysts were detected in eight patients. In five patients, fat signal appeared on follow-up imaging. No major side effects were observed during treatment. Median follow-up time after treatment was 15 months. At 5 months, severe hypercalcemia was observed in two patients due to rebound increase in osteoclastic activity. Subsequent to denosumab treatment, three patients underwent surgery for clinical or radiological recurrence. CONCLUSIONS Our results showed that denosumab provided a meaningful clinical and radiological improvement in ABC. It may be a treatment option, especially in spinal and pelvic tumors with potentially high surgical morbidity. However, late rebound hypercalcemia may restrict its use. Studies with more cases are required for routine use of denosumab in ABC.

Abstract
BACKGROUND The outcome of bone and soft tissue sarcomas (BST) after relapse has very poor prognosis with survival rates less than 39%. Unfortunately there are not many treatment options, but promising responses have been reported with ifosfamide, etoposide and carboplatin (ICE). OBJECTIVE Therefore, we planned a study for children with recurrent/refractory BST treated with ICE regimen to evaluate their demographic features, responses to treatment and outcome. METHOD Patients with primary diagnosis of BST and treated with ICE regimen at the time of first or subsequent relapse, progression or unresponsive disease were selected for study. The files were retrospectively evaluated. RESULTS Thirty of sixty-six patients had metastatic disease at relapse. Patients received median 5 cycles of ICE and were followed-up median 16.3 months. Overall survival rates were 83% and 62% at 1st and 2nd year. The ORR to the regimen was 43%. Survival rates were significantly higher in good responders (3-year EFS and OS rates: 50% vs. 8% and 78% vs. 14%; p<0.0001 and p<0.0001). Survival rates for non-metastatic disease were 42% and 75% for EFS and OS and higher than patients with metastases at relapse (p<0.001 and p<0.0001). EFS and OS rates of patients with rhabdomyosarcoma were 42% and 69%. No grade 3 or 4 renal toxicity was documented. CONCLUSION ICE combination improves the outcome of relapsed or refractory sarcomas and it might serve as second line treatment. Patients with no metastases at relapse would benefit more than others with metastatic disease.

Abstract
Pituitary apoplexy (PA) is a life-threatening clinical syndrome. Dopamine receptor agonists are the drugs of choice in the treatment of prolactinomas. The use of cabergoline is reported to cause an increased risk of PA, particularly in macroprolactinomas of cystic nature. In this report, we present a patient with a cystic macroprolactinoma who developed PA on the 16th week of cabergoline treatment.

Abstract
As the popularity of the personal watercraft (PWC) or Jet Ski increases, injuries suffered from the usage of them become more common. Most severe injuries in this setting are typically related to blunt head trauma. Here we present an unusual case of hydrostatic injury to the rectum and sigmoid colon due to exposure to a high-pressure jet stream of water in a passenger thrown from the rear of a PWC. In addition, a review of the literature of similar cases is briefly discussed. (Hong Kong j.emerg.med. 2014;21:322-325)

Abstract
BACKGROUND Lipoblastoma is a rare benign mesenchymal tumor of infancy and early childhood. Symptoms vary depending on localization, and signs of compression of adjacent organs may be seen. METHODS A total of 12 children with pathologically proven lipoblastoma from 2000 to 2014 were reviewed retrospectively for their clinical features, treatment and follow up. RESULTS There were seven boys and five girls between 7.5 months and 7.5 years of age. The most common symptom was painless rapid-growing mass. The tumors were located in the neck, the abdomen, the groin, pelvis, axilla, glutea, labium majus, thigh and trunk. The largest tumor was in a retroperitoneal location and was 13 × 10 cm in size. Complete resection was performed in 10 patients. All of these patients were followed without any evidence of recurrence. Subtotal excision was performed in two patients. At a median follow up of 38 months (range, 1.8 months-10 years), all patients were disease free. CONCLUSIONS Lipoblastoma should be considered in the differential diagnosis of rapidly growing mass in patients <3 years of age. Total excision is the treatment of choice with preservation of vital organs. The prognosis is excellent despite large tumor size and local invasion. Recurrence rate is high in incompletely resected tumors. Regular follow up is important for early detection of recurrence.

Abstract
Oligomeric proanthocyanidins (OPACs) are potent and renewable natural bioactives possible to be refined into chemically standardized mixtures for biological applications. Herein, we found that multiscale interactions of OPACs with the dentin matrix create tight biointerfaces with hydrophobic methacrylate adhesives on wet surfaces. An enriched mixture of OPACs, with a known phytochemical profile, was produced from grape seed crude extract ( Vitis vinifera; enriched grape seed extract [e-GSE]) and applied to dentin matrices to determine changes to the mechanical properties and biodegradability of the dentin matrix and favorable resin adhesion mechanisms. Methods included a 3-point flexural test, quantification of hydroxyproline (collagen solubilization), static and dynamic nanomechanical analyses, resin-dentin microtensile bond strength, and micropermeability at the adhesive interface. The e-GSE-modified dentin matrix exhibited remarkably low collagen solubilization and sustained the bulk elastic properties over 12 mo. Tan δ findings reveal a more elastic-like behavior of the e-GSE-modified dentin matrix, which was not affected by H-bond destabilization by urea. Dentin-methacrylate biointerfaces with robust and stable adhesion were created on e-GSE-primed dentin surfaces, leading to a dramatic decrease of the interfacial permeability. Standardized OPAC mixtures provide a new mechanism of adhesion to type I collagen-rich tissues that does not rely on hydrophilic monomers. The bioadhesion mechanism involves physicochemical modifications to the dentin matrix, reduced tissue biodegradation, and bridging to methacrylate resins.

Abstract
INTRODUCTION Acute mesenteric ischemia (AMI) is an abdominal-vascular emergency which is rare and has high mortality rates (60-80 %) due to late diagnosis (1-3). Although it is known that extravascular reasons like intestinal intussusception, volvulus, strangulated hernias and obstructions can cause intestinal gangrene, these are rarely the cause of AMI (1). MATERIALS AND METHODS In this study, we used male Wistar-Albino rats weighing 250-300 grams obtained from Pamukkale University Experimental Research Laboratory. Animals were exposed to light-dark cycles for 12 hours and had free access to food and water. They were kept in cages for 7 days to stabilise their intestinal flora. In animals of group I, nothing was made other than taking 0.5 ml blood intracardially. In other animals, abdomen was reached with midline laparotomy and superior mesenteric artery (SMA) was located. In group II (operative control group), SMA was isolated and manipulated but was not ligated. In Group III (intestinal ischemia group), SMAwas isolated and ligated with 3/0 silk tie distally to the aorta. After this process, intestinal ischemia was achieved which was confirmed by paleness and pulselessness of intestines, caecum and right colon. Later on, abdomen was closed with double 3/0 polyglactin sutures. At postoperative 1st, 4th and 6th hours 0.5 ml blood was taken intracardially from the animals in groups II and III in order to quantify D-dimer and L-lactate levels. LABORATORY TESTS D-dimer: Blood samples which were put into tubes containing sodium citrate, were seperated from plasma with centrifugation at 4000 rpm for 7 minutes.L-lactate: Blood L-lactate levels were determined from blood taken into capillary tubes with the help of immobilised enzyme electrode technology using YSI 1500 Sport portative lactate analyzer (Yellow Springs Instruments Inc., Ohio-USA). HISTOPATHOLOGIC VERIFICATION Two cm long intestinal samples were taken from animals in which SMA was ligated in order to achieve mesenteric ischemia and these samples were fixed in 10 % formol. DISCUSSION As a result, in rats with SMA occlusion serum D-dimer levels were not increased significantly when compared either in the group or with the basal values of the control group and values in operative control group. Therefore, it is concluded that D-dimer is not a useful marker for early diagnosis of AMI. On the other hand, it is revealed that blood L-lactate levels began to increase significantly following 4th hour of mesenteric ischemia and it is shown that this increase continued at the 6th hour. In addition, considering the utmost importance of the early diagnosis in patients with the clinical suspicion of AMI, L-lactate seems to be a suitable marker to use in emergency departments because it is achieved with a portable device that gives fast and accurate results. Nevertheless, our results are need to be supported by clinical studies with larger patient series (Tab. 2, Fig. 11, Ref. 39).

Abstract
OBJECTIVES We aimed to assess the effect of anemia on subjective sleep quality in patients with iron deficiency anemia (IDA). METHODS One hundred and four patients diagnosed with IDA and 80 healthy individuals, who are gender and age matched, were included in the study. All participants were requested to fill 3 forms: a socio-demographic form (age, gender, marital status, income level and educational status), hospital anxiety and depression (HAD) scale and pittsburgh sleep quality index (PSQI). RESULTS According to the HAD scale, the average anxiety score was found 9.24±4.37 in patients and 7.58± 4.07 in controls. And, the average depression score was 7.53±4.10 in patients and 6.41±2.74 in controls. The total sleep quality score was 6.71±3.02 in patients and 4.11±1.64 in controls. There was a statistically significant difference in terms of anxiety, depression and sleep quality scores. Linear regression analysis showed no association between anxiety and depression with poor sleeping. CONCLUSION IDA affects sleep quality irrespective of psychological symptoms such as depression and anxiety.

Abstract
OBJECTIVE Serious health problems in humans are caused by arsenic (As) exposure, which is wide spread in the environment. Sodium arsenite (SAs), capable of inducing macromolecular damage is evaluated for its damaging effect in the blood vessels, liver and kidneys of Wistar rats. This study was undertaken to investigate the ameliorative effects of thymoquinone on SAs-induced oxidative and inflammatory damages in the serum of male Wistar rats. MATERIALS AND METHODS Wistar Albino rats divided into three groups of nine rats each were administered to controls saline (10 mg/kg), SAs (10 mg/kg), and SAs plus thymoquinone (10 mg/kg/day) for two weeks orally. Biochemical tests were analyzed by a otoanalyzer; nitric oxide levels specthrophometrically, and cytokines were measured by ELISA method in the rat serum samples. RESULTS Inflammatory cytokines and some biochemical variables were found to be increased in the SAs group compared to control group. On the other hand, thymoquinone supressed these laboratory signs, which are thought to be the characteristic signs of SAs toxicity, most probably by its ameliorative effects including anti-inflammatory and antioxidant properties. CONCLUSIONS From the results obtained, thymoquinone mitigates SAs-induced adverse effects in the serum of rats, which suggest that it may attenuate inflammation implicated in endotelial dysfunction.

Abstract
The aim of this study was to describe maternal and fetal characteristics associated with intrahepatic cholestasis of pregnancy (ICP) and to determine clinical and biochemical predictors of fetal complications. A total of 89 singleton pregnancies with ICP were analysed, retrospectively. All data concerning laboratory results, symptom onset time, treatment response, delivery time and infant information were recorded in the study protocol. The mean gestational age at diagnosis was 32.6 ± 3.4 weeks; mean time of delivery was 36.8 ± 1.9 weeks. Binary logistic regression revealed that gestational age at diagnosis was predictive of preterm delivery (OR = 2.3, 95% CI: 1.5-3.3, p = 0.001). The incidence of respiratory distress syndrome (RDS), fetal growth restriction, fetal distress and preterm delivery were significantly higher in patients who were diagnosed before 30 weeks than after 34 weeks' gestation (p < 0.01). Gestational age at diagnosis is an important independent factor predicting adverse perinatal outcomes in patients with ICP.

Abstract
Defects in the corneal stroma caused by trauma or diseases such as macular corneal dystrophy and keratoconus can be detrimental for vision. Development of therapeutic methods to enhance corneal regeneration is essential for treatment of these defects. This paper describes a bioactive peptide nanofiber scaffold system for corneal tissue regeneration. These nanofibers are formed by self-assembling peptide amphiphile molecules containing laminin and fibronectin inspired sequences. Human corneal keratocyte cells cultured on laminin-mimetic peptide nanofibers retained their characteristic morphology, and their proliferation was enhanced compared with cells cultured on fibronectin-mimetic nanofibers. When these nanofibers were used for damaged rabbit corneas, laminin-mimetic peptide nanofibers increased keratocyte migration and supported stroma regeneration. These results suggest that laminin-mimetic peptide nanofibers provide a promising injectable, synthetic scaffold system for cornea stroma regeneration.

Abstract
Treacher Collins syndrome is an autosomal dominant disorder of craniofacial development with an incidence of I in 40,000 to in 70,000 live births. It is characterized by abnormalities of the pinnae which are frequently associated with atresia of the external auditory canals and anomalies of the middle ear ossicles. Rarely congenital heart defects can be present. Prenatal paroxetine exposure may enhance the risks of major malformation, particularly cardiac defects. This article reports a newborn, whose mother used paroxetine during pregnancy, presenting with multiple congenital heart defects associated to typical physical characteristics of Treacher Collins syndrome.

Abstract
Crisponi syndrome (CS) is a rare, autosomal recessive disorder, characterized by hyperthermia, extensive muscular contractions in the face after even minimal stimuli or crying, hypertonia, opisthotonus, camptodactyly, and typical facial features. Recently, it has been demonstrated that CRLF1 (cytokine receptor-like factor 1) gene mutation is associated with CS. Here we report a case of CS with a new mutation in the CRLF1 gene associated with moderate clinical phenotype.

Abstract
Renal hypoplasia is a congenital anomaly, the etiology of which is not yet fully known. Genetic studies have shown that certain genes, in utero environmental factors and molecular mechanisms have a role in the identification ofnephron formation and kidney size. The coexistence of bilateral renal hypoplasia and optic disc coloboma is observed in papillorenal syndrome, which caused by the mutation of the PAX2 gene. In the case presented in this article, bilateral renal hypoplasia and optic disc coloboma have been detected to coexist. The analysis of the PAX2 gene, which was carried out with an eye to the papillorenal syndrome, did not reveal any mutations. However, de novo t(2;15) (q31; q26) (reciprocal translocation) was detected in chromosome analysis. As far as we know, there are not any publications focusing on the clinical importance of this type of translocation. In cases with renal hypoplasia and optic disc coloboma, the possibility of a de novo translocation between chromosomes 2 and 15 should be considered.

Abstract
Pierson syndrome is a rare autosomal recessive disorder which is mainly characterized by congenital nephrotic syndrome (CNS), diffuse mesangial sclerosis (DMS) and distinct ocular abnormalities, including microcoria. Most affected children exhibit early onset of chronic renal failure, neurodevelopmental deficits, and blindness. It is caused by a homozygous or compound heterozygous mutation in the gene encoding laminin beta2 (LAMB2) on chromosome 3p21. In this article, we report on a patient with CNS, bilateral megalocornea and microcoria. The patient had developed renal failure at very early postnatal period and died of septic shock. A novel homozygous donor splice mutation (IVS4 + 2T > C) in LAMB2 gene was identified in the patient.

Abstract
AIM Numerous chemotherapeutics are used in the treatment of high-grade glioma (HGG). The purpose of this study was to evaluate the therapeutic value of vincristine (VCR) in the treatment of HGGs. MATERIALS AND METHODS A meta-analysis of HGG studies was performed to evaluate and compare the efficacy of chemotherapy drugs using observed and predicted median overall survival and survival gain as previously described. RESULTS Patient cohorts treated with VCR-containing-regimens had a significant survival gain advantage over cohorts treated with other chemotherapy drugs (p<0.0001). VCR was most effective in treating newly diagnosed adult (p<0.0001) and elderly (p=0.0001) patients. When VCR was combined with nimustine, carmustine, cytarabine or etoposide, the effect was antagonistic, but when VCR was combined with lomustine, procarbazine, cyclophosphamide, dacarbazine, hydroxyurea, or cisplatin it was synergistic. CONCLUSION Results from this study suggest that VCR should be included in chemotherapy regimens for patients being treated for newly diagnosed or recurrent HGG.
