Abstract
Aneurysmal bone cysts constitute 1% to 2% of all primary bone tumors.They are rapidly growing benign bone tumors. Nearly 80% of aneurysmal bone cysts occur in the first 20 years of life, and most are primary tumors. Aneurysmal bone cysts are mostly benign, locally aggressive, and highly vascularized tumors. Generally, the period required for postoperative recovery and new bone formation is long. The relapse rate can be up to 50%. Although computed tomography and magnetic resonance imaging scans are the preferred diagnostic methods, biopsy is the most necessary prerequisite to confirm diagnosis, as aspects of these cysts can show similarity to many other bone lesions. Correct histopathologic diagnosis is important since malignancies may be seen in transplant recipients.

Abstract
Drug and alcohol use in adolescence is a major global public health concern. Adolescence is the highest risk period for the initiation of drinking and substance use. Since the 90s, a growing body of evidence has indicated the influence of peers’ behaviours and attitudes in the development of youth tobacco, alcohol and drug use. Based on these studies, the social norms approach has been developed, mainly applying to the Western countries. The approach argues that how a student perceives his/her peers’ health-related behaviours and attitudes (such as substance/alcohol use) does have an influence on his/her own behaviour, and negative behaviours are generally overestimated among peers. Correcting these misperceptions may contribute to the prevention of youth substance/alcohol use. The applicability and discussions on the social norms approach will be presented in this talk, with two example studies. Both studies are conducted in Turkey, which is ranked lowest in terms of alcohol use and related problems among World Health Organization Europe zone countries, despite and increasing trend in use over the past decades. In both university and high-school samples, we found that students’ misperceptions about higher peer tobacco and alcohol use facilitated their own alcohol use. We conclude that targeting social norms may be part of a generalized preventive approach with regards to drug use and is of universal value. References: 1. SÖNMEZ, E. & AKVARDAR, Y. 2015.

Abstract
IntroductionGermany is one of the European countries that receive the highest number of refugees for the last years, with around 468 thousand asylum seekers in the first half of 2016. However, the increase in the speed of short-term procedures regarding refugees may at the same time overlook the risks regarding specific populations. Moreover, women and children constitute the most vulnerable groups during war and conflicts and the worst effects, in terms of physical, mental and social consequences, develop on these groups.ObjectivesTo understand deeply the psychosocial situation of female refugees that have arrived in Federal German Republic, to assess their challenges and resources before, during and after the displacement and to propose recommendations for policy changes.MethodsThe study consists of two modules, taking place in five states in Federal German Republic, including Berlin, Mecklenburg-Vorpommern, Bayern, Hessen und Mainz. In the first step, a representative stratified sample of female refugees from Syria, Iraq, Iran, Afghanistan, Somali and Eritrea are recruited. The quantitative study instrument include a socio-demographic question form and HSCL-Hopkins checklist, Harvard Trauma questionnaire, Beck depressions inventory, EUROHIS–QOL and SCL-14. In the second step, a qualitative in-depth analysis of focus group meetings is conducted.Results and conclusionsThere is an urgent need to take action for the mental health problems of refugees. This study constitutes one of the most extensive researches, especially on a subpopulation of refugees that requires specific attention. Challenges faced throughout the protocol and detailed results will be shared as presentation.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Ependymomas are the most common intramedullary spinal tumors in adults and constitute around 20% of all spinal tumors in adults. There are 3 subgroups of ependymomas according to World Health Organization classification: subependymoma or myxopapillary (grade 1), ependymoma (grade 2), and anaplastic (grade 3). Therapy for patients is aimed at safe and total surgical removal and, in selected cases, postoperative radiotherapy. Bleeding from a spinal ependymoma, with subsequent urgent surgery, is extremely rare. Here, we present a case of a renal transplant patient who had a cervical ependymoma. Although a considerable volume of peritumoral blood was observed during surgery, the patient had no neurologic deficits and no signs of deterioration.

Abstract
PURPOSE Spinal disorders, including back and neck pain, are major causes of disability, economic hardship, and morbidity, especially in underserved communities and low- and middle-income countries. Currently, there is no model of care to address this issue. This paper provides an overview of the papers from the Global Spine Care Initiative (GSCI), which was convened to develop an evidence-based, practical, and sustainable, spinal healthcare model for communities around the world with various levels of resources. METHODS Leading spine clinicians and scientists around the world were invited to participate. The interprofessional, international team consisted of 68 members from 24 countries, representing most disciplines that study or care for patients with spinal symptoms, including family physicians, spine surgeons, rheumatologists, chiropractors, physical therapists, epidemiologists, research methodologists, and other stakeholders. RESULTS Literature reviews on the burden of spinal disorders and six categories of evidence-based interventions for spinal disorders (assessment, public health, psychosocial, noninvasive, invasive, and the management of osteoporosis) were completed. In addition, participants developed a stratification system for surgical intervention, a classification system for spinal disorders, an evidence-based care pathway, and lists of resources and recommendations to implement the GSCI model of care. CONCLUSION The GSCI proposes an evidence-based model that is consistent with recent calls for action to reduce the global burden of spinal disorders. The model requires testing to determine feasibility. If it proves to be implementable, this model holds great promise to reduce the tremendous global burden of spinal disorders.

The Global Spine Care Initiative: classification system for spine-related concerns. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2018; 27:889-900. [PMID: 30151807 DOI: 10.1007/s00586-018-5724-8] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2018] [Accepted: 08/06/2018] [Indexed: 10/28/2022]
Abstract
PURPOSE The purpose of this report is to describe the development of a classification system that would apply to anyone with a spine-related concern and that can be used in an evidence-based spine care pathway. METHODS Existing classification systems for spinal disorders were assembled. A seed document was developed through round-table discussions followed by a modified Delphi process. International and interprofessional clinicians and scientists with expertise in spine-related conditions were invited to participate. RESULTS Thirty-six experts from 15 countries participated. After the second round, there was 95% agreement of the proposed classification system. The six major classifications included: no or minimal symptoms (class 0); mild symptoms (i.e., neck or back pain) but no interference with activities (class I); moderate or severe symptoms with interference of activities (class II); spine-related neurological signs or symptoms (class III); severe bony spine deformity, trauma or pathology (class IV); and spine-related symptoms or destructive lesions associated with systemic pathology (class V). Subclasses for each major class included chronicity and severity when different interventions were anticipated or recommended. CONCLUSIONS An international and interprofessional group developed a comprehensive classification system for all potential presentations of people who may seek care or advice at a spine care program. This classification can be used in the development of a spine care pathway, in clinical practice, and for research purposes. This classification needs to be tested for validity, reliability, and consistency among clinicians from different specialties and in different communities and cultures.

Abstract
PURPOSE The purpose of this report is to describe the Global Spine Care Initiative (GSCI) contributors, disclosures, and methods for reporting transparency on the development of the recommendations. METHODS World Spine Care convened the GSCI to develop an evidence-based, practical, and sustainable healthcare model for spinal care. The initiative aims to improve the management, prevention, and public health for spine-related disorders worldwide; thus, global representation was essential. A series of meetings established the initiative's mission and goals. Electronic surveys collected contributorship and demographic information, and experiences with spinal conditions to better understand perceptions and potential biases that were contributing to the model of care. RESULTS Sixty-eight clinicians and scientists participated in the deliberations and are authors of one or more of the GSCI articles. Of these experts, 57 reported providing spine care in 34 countries, (i.e., low-, middle-, and high-income countries, as well as underserved communities in high-income countries.) The majority reported personally experiencing or having a close family member with one or more spinal concerns including: spine-related trauma or injury, spinal problems that required emergency or surgical intervention, spinal pain referred from non-spine sources, spinal deformity, spinal pathology or disease, neurological problems, and/or mild, moderate, or severe back or neck pain. There were no substantial reported conflicts of interest. CONCLUSION The GSCI participants have broad professional experience and wide international distribution with no discipline dominating the deliberations. The GSCI believes this set of papers has the potential to inform and improve spine care globally. These slides can be retrieved under Electronic Supplementary Material.

Abstract
PURPOSE The purpose of this report is to describe the development of an evidence-based care pathway that can be implemented globally. METHODS The Global Spine Care Initiative (GSCI) care pathway development team extracted interventions recommended for the management of spinal disorders from six GSCI articles that synthesized the available evidence from guidelines and relevant literature. Sixty-eight international and interprofessional clinicians and scientists with expertise in spine-related conditions were invited to participate. An iterative consensus process was used. RESULTS After three rounds of review, 46 experts from 16 countries reached consensus for the care pathway that includes five decision steps: awareness, initial triage, provider assessment, interventions (e.g., non-invasive treatment; invasive treatment; psychological and social intervention; prevention and public health; specialty care and interprofessional management), and outcomes. The care pathway can be used to guide the management of patients with any spine-related concern (e.g., back and neck pain, deformity, spinal injury, neurological conditions, pathology, spinal diseases). The pathway is simple and can be incorporated into educational tools, decision-making trees, and electronic medical records. CONCLUSION A care pathway for the management of individuals presenting with spine-related concerns includes evidence-based recommendations to guide health care providers in the management of common spinal disorders. The proposed pathway is person-centered and evidence-based. The acceptability and utility of this care pathway will need to be evaluated in various communities, especially in low- and middle-income countries, with different cultural background and resources.

Abstract
Neurologic complications after solid-organ transplant reveal a great spectrum of pathologies. Intracranial hemorrhages, cerebral ischemic lesions, infarctions, lymphoproliferative disorders, and infections, including aspergillosis, have been observed after liver transplant. Fungi constitute nearly 5% of all central nervous system infections, mainly occurring in immunocompromised patients. The most common causative agent is Aspergillus species. It presents either as maxillary sinusitis or pulmonary infection. Brain involvement of Aspergillus carries a high rate of mortality. Aspergillosis presents in the forms of meningitis, mycotic aneurysms, infarctions, and mass lesions. Aspergillosis does not have a specific radiologic appearance. Parenchymal aspergillosis has heterogenous signal intensity (hypointense on T1-weighted and hyperintense on T2-weighted images). Here, we present 3 patients who underwent solid-organ transplant and developed central nervous system aspergillosis. Different modalities of neurosurgical intervention were performed in combination with chemotherapy as part of their fungal therapy.

Abstract
IntroductionApproaching and offering treatment to a patient in perinatal period might be complicated. Often, it is regarded as one of the most difficult aspects in psychiatry. Given the increasing trends in the number of female patients of childbearing age consulting to psychiatric services, it has become an issue that specialists of today and tomorrow need to be well aware of.ObjectivesTo better understand the impact of perinatal mental health training on psychiatric trainees from different countries in Europe who receive such training.MethodsThe European Federation of Psychiatric Trainees conducts annual surveys, directing questions to national trainee representatives, to assess the situation of psychiatric training. EFPT representatives of the countries where perinatal mental health training was reported to be included in psychiatry and/or child and adolescent psychiatry training programmes, namely Germany, France, Malta, Finland and Ireland, were contacted. Qualitative interviews focusing on the confidence (or in confidence) trainees feel when a patient who is planning pregnancy, pregnant or breastfeeding consults to them and the impact of training in perinatal mental health on their attitudes as clinicians were explored.ResultsAlthough theoretical training in perinatal mental health is considered as an important aspect of psychiatry training in general, practical training or rotations are not found as essential. However, being able to benefit to more than one generation was perceived as a source of motivation.ConclusionsPerinatal mental health is appreciated as a critical part of theoretical education by trainees and in countries where a clinical rotation is available, it enhances making more use of resources and consultation possibilities.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionMental disorders are one of the leading reasons for disability-related retirement and payment of associated long-term benefits in many countries.ObjectivesTo explore the characteristics of psychiatric outpatients who apply for disability pensions and to investigate the factors associated with making an application.MethodsA four-month cross-sectional evaluation of disability pension and retirement applications to the psychiatry outpatient clinic in a university hospital in Istanbul.ResultsThe majority of 144 patients were male (n = 102, 70.8%), based in Istanbul, married, living with their families and had no occupation at the time of inquiry. Excluding applications for individuals with a diagnosis of intellectual disability (n = 44), most applicants were primary school graduates (n = 31, 32.3%). For the whole group, the median age of application was 34. 60%, (n = 87) had an established psychiatric diagnosis before the application, with average duration since diagnosis of approximately 8 years. The most frequent diagnoses were intellectual disability, followed by schizophrenia and depression. More than half of the patients were treated only outpatiently, with no hospitalization (n = 55, 58%). Thirty-two of them (22.4%) had a comorbid psychiatric diagnosis and 58 (40.3%) had at least one comorbid medical diagnosis.ConclusionsThere are some similarities between our findings and findings from other countries, such as low educational level and frequent comorbid somatic diseases among patients applying for disability pension. In contrast with the literature and as an indicator of social inequality, most patients applied for disability pension were male. The results are reflecting the specificities of different health systems and cultural perceptions of disability.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
The functional recovery of a replanted body part is as important as its viability. We compared four instruments frequently used for the evaluation of hand function after digital replantation. The functional results of 17 patients at least one year after replantation of a total digital amputation between 2004 and 2007 were evaluated according to the Tamai, Ipsen, Chen and Disabilities of the Arm, Shoulder and Hand questionnaires. Scores of each patient for each test were calculated and intra-individual comparisons were made. Correlation was significant at the 0.05 level (two tailed) for all tests. A high correlation (>0.71) was found between the Ipsen, Tamai and DASH tests. The Chen test had a moderate correlation with the other tests. We determined that Ipsen, Tamai and DASH tests have similar effectiveness in assessing hand function after replantation.

Abstract
Tarsal tunnel syndrome (TTS) is defined as the entrapment of the posterior tibial nerve in the tarsal tunnel of the ankle. The etiologies of tarsal tunnel syndrome are mainly the presence of a ganglion, osseous prominence with tarsal bone coalition, trauma, varicose veins, neurinoma, hypertrophy of the flexor retinaculum, or systemic disease (rheumatoid arthritis, ankylosing spondylitis). However, no specific cause can be identified in some cases. Patients with chronic renal failure tend to develop peripheral nerve entrapment and carpal tunnel syndrome is the best-known peripheral entrapment neuropathy among them. Contrary to carpal tunnel syndrome, tarsal tunnel syndrome is observed less frequently in chronic renal failure patients. The common presenting symptoms of TTS are paresthesias and/or pain in the plantar side of the foot. Motor symptoms are rarely detected. Diagnosis is made primarily by electroneuromyographic studies and physical examination. Surgery is the treatment of choice and the outcome is generally favourable. In this report, we present a patient with tarsal tunnel syndrome complicating peritoneal dialysis.

Abstract
Application of the thin-layer wicking (TLW) technique on powdered minerals is useful for characterizing their surfaces. Albite (Na-feldspar) and orthoclase (K-feldspar) are feldspar minerals which are frequently found in the same matrix. Despite similarities in their physicochemical properties, separation of these minerals from each other by flotation is generally possible in the presence of monovalent salts such as NaCl. Both albite and orthoclase exhibit the same microflotation properties and rather close electrokinetic profiles in the absence of salt. In this study, contact angles of albite and orthoclase determined by the TLW technique yielded close values in the absence and presence of amine collector. While the calculated surface energies and their components determined using contact angle data reveal that the energy terms remain farther apart in the absence of the collector, the differences narrow down at collector concentrations where full flotation recoveries are obtained. However, the effect of addition of NaCl on contact angles and surface free energy components at constant amine concentration indicates that albite is significantly affected by salt addition, whereas orthoclase remains marginally affected. This interesting finding is explained on the basis of ion-exchange properties, the stability of the interface, flotation data, and zeta potential data in the presence of NaCl.

Abstract
In recent years, several articles have been published about BCG tests in the diagnosis of tuberculosis, particularly in children. The test is reportedly more sensitive and more specific than tuberculin test (PPD). We evaluated the results of simultaneous application of PPD and BCG test in order to assess its efficacy in adults and adolescents with tuberculosis (tbc). We applied BCG test and PPD concurrently in 35 healthy controls and 41 tuberculosis cases presented to Research Hospital, Inönü University and Malatya Tuberculosis Dispensary with clinical and radiological findings. The subjects also had sputum examined for presence of acid-fast bacilli (AFB) by direct microscopy, culture on Lowenstein Jensen medium and by polymerase chain reaction (PCR). We conclude that BCG test is more sensitive and more specific than PPD in diagnosis of tuberculosis in adults and adolescents.

Abstract
In this study, the distributions of Anti-HSV 1 and HSV 2 IgG and IgM antibodies have been investigated in sera obtained from 296 pregnant women who were admitted to the gynecology clinics of Medical Faculty of Atatürk University, Erzurum, Turkey. While the 24 (8.11%) of 287 HSV 1 IgG antibody positive patients were IgM positive but Anti-HSV 1 IgM alone was not detected in any patients. On the other hand, in 16 (5.41%) of 125 (42.23%) patients who were Anti-HSV 2 IgG antibody positive, HSV 2 IgM antibodies were detected too. In the 4 patients (1.35%), HSV 2 IgM antibodies were detected alone.
