The European Association of Tissue Banks (EATB) donor case workshop is a forum held within the program of the EATB annual congress. The workshop offers an opportunity to discuss and evaluate possible approaches taken to challenging situations regarding donor selection. Donor case workshops actively engage participants with diverging background and experience in an informal, secure and enjoyable setting. The resulting discussion with peers promotes consensus development in deciding tissue donor acceptability, especially when donor health issues are not conclusively addressed in standards and regulations. Finally the workshop serves to strengthen the professional tissue banking networks across Europe and beyond. This report reflects some of the discussion at the workshop during the annual congress in Lund, Sweden, in 2014. The cases presented demonstrate that the implications of various donor illnesses, physical findings and behaviours on the safety of tissue transplantation, may be interpreted in a different way by medical directors and other professionals of different tissue facilities. This will also result in diverging preventive measures and decisions taken by the tissue facilities. Some of the donor cases illustrate varied responses from participants and demonstrate that operating procedures, regulations and standards cannot comprehensively cover all tissue donor illnesses, medical histories and circumstances surrounding the cause of death. For many of the issues raised, there is a lack of published scientific evidence. In those cases, tissue bank medical director judgement is critical to guarantee transplantation safety. This judgement should be based on a proper and documented risk assessment case by case. Conditions or parameters taken into account for risk assessment are amongst others, the type of tissue, the type of processing, the characteristics of the final product, and the availability of an adequate sterilisation methodology. By publishing these difficult donor suitability cases, and the resulting discussions, we provide information for future similar cases and we identify needs for future literature review and scientific research. In this way the donor case workshops play a role in optimizing the quality and security of tissue donation.  相似文献

The European Association of Tissue Banks (EATB) Donor Case Workshop is a forum held within the programme of the EATB annual Congress since 2003. This workshop has been used to discuss clinical donor cases with peer review of practice. It was agreed in advance that the experience of the 2007 workshop should be shared by publication as an example of participative learning which can be extended to other fields within tissue banking and which may be applicable in other disciplines. The EATB Congress in 2008 will extend the idea of participative open workshops with two additional workshops, one on Quality System cases and another on heart valve cases.  相似文献

The European Association of Tissue Banks (EATB) donor case workshop is a forum held within the program of the EATB annual congress. The workshop offers an opportunity to discuss and evaluate approaches taken to challenging situations regarding donor selection, it promotes consensus development in deciding tissue donor acceptability when donor health issues are not addressed in standards and regulations, and serves to strengthen the professional tissue banking networks across Europe and beyond. This report reflects some of the discussion at the workshop during the annual congress in Vienna in 2012. The cases presented dealt with problems encountered by tissue bank facilities concerning idiopathic thrombocytopenia and auto-immune disorders, hemodilution and blood sample identification, premalignant and malignant lesions, and Huntington’s disease. The discussions during the workshop demonstrate that the implications on the safety of tissue transplantation of various tissue donor illnesses, physical findings and behaviours, and the preventive measures taken by tissue facilities, may not always be agreed by tissue facility medical directors and other professionals. Moreover, they reveal that operating procedures, regulations and standards cannot comprehensively cover all tissue donor findings, medical histories and circumstances surrounding the cause of death. For many of the issues raised, there is a need for scientific research to provide a better evidence base for future deliberations about the suitability and eligibility of tissue allograft donors.  相似文献

The 17th Annual Meeting of the European Association of Tissue Banks (EATB) was held in Edinburgh in November 2008 together with the British Association for Tissue Banking (BATB) and received excellent evaluation by its participants. The meeting included, for the first time, a cardiovascular symposium co-organised by EATB and BATB together with the American Association of Tissue Banks (AATB). This was a first in terms of collaboration for the three associations. The many professionals involved in organising the meeting created an excellent clinical and scientific programme including regulatory issues and featured, also for the first time three interactive workshops about clinical donor cases, quality management and cardiovascular allografts.  相似文献

The Cardiovascular Tissue Banking Standards are designed as an addition to the General Standards of the European Association of Tissue Banks to provide a minimum acceptable level for the donation, processing, storage, testing, labelling and distribution of cardiac tissue throughout Europe. The aim is that all heart valve banks in Europe should work to these Standards so that heart valves can be exchanged between countries without having to check the individual protocols of the donor processing facility. The writing of the Standards has been performed by the Heart Valve Council of EATB with input from cardiac surgeons. It is proposed that once the Standards are accepted they will form the document on which EATB may accredit tissue banks in the future and may form the basis on which National Legislation for Tissue Banking is based.  相似文献

A series of workshops held in the 1970s and 1980s, beginning at the University of Michigan Biological Station near Pellston, Michigan (and thus called the Pellston Series), focused on identifying the basic tenets of ecological hazard/risk assessment. The purpose of this discussion, produced roughly two decades after the first Pellston workshop, is to examine the impacts of this series on the development of the ecological hazard/risk assessment process, to explore some barriers hindering the development of this process, and suggest some new directions and challenges yet unaddressed by any of the workshop series. Probably the most important factor identified since the series of workshops began is persuasive circumstantial evidence that the learning process proceeds at different rates for individuals and institutions both in the government and private sectors, including academe. Evidence presently available suggests that individuals are frequently two or three decades ahead of institutions, and some individuals have already rejected paradigms generally accepted by the profession and are developing new ones. The major contribution of the workshops to the profession was connecting toxicity with environmental fate and transformation of chemicals and thus, bioavailability. Astonishingly, before the first Pellston workshop, this now-obvious connection did not play a dominant role in the peer-reviewed professional literature or in government documents, although the indefatigable investigator could find some minor indications that some professionals were aware of the importance of these relationships. Major suggestions for new directions and challenges focus on: (1) an emphasis on ecosystem health or condition rather than on mere absence of deleterious effects; (2) entering the information age requires that the type of information discussed here be integrated with and related to the broader array of other types of information used in making decisions at the societal or system level — failure to do so will mean that hazard/risk information will have little or no impact; (3) restoration ecology must emerge as a field of considerable importance because inevitably some estimates of hazard/risk will be inaccurate and damage will be done to ecosystems, which must then be repaired; (4) for all of this to function, environmental literacy must be markedly improved over its present level.  相似文献

Hamartoma designates an excessive focal overgrowth of mature normal cells and tissues in an organ or tissue composed of identical cellular elements. Two cases of hamartoma at the back of the tongue are reported. Histologically they comprised fibrous tissue, fat, salivary gland lobules, and smooth muscle. The literature is reviewed and discussed.  相似文献

Background

Non-organic lesions or diseases of unknown origin are sometimes misdiagnosed as “psychogenic” disorders or “psychosomatic” diseases. For the quality of life and safety of patients, recent attention has focused on diagnostic error. The aim of this study was to clarify the factors that affected misdiagnoses in psychosomatic medicine by examining typical cases and to explore strategies that reduce diagnostic errors.

Case presentation

The study period was from January 2001 to August 2017. The data of patients who had visited the Department of Psychosomatic Medicine, Kindai University Hospital and its branches, Sakai Hospital and Nihonbashi Clinic, were collected. All patients were aged 16 years or over. Multiple factors, such as age, sex, presenting symptoms, initial diagnosis, final diagnosis, sources of re-diagnosis and types of diagnostic errors were retrospectively analyzed from the medical charts of 20 patients. Among them, four typical cases can be described as follows. Case 1; a 79-year-old woman, initially diagnosed with psychogenic vomiting due to depression that was changed to gastric torsion as the final diagnosis. Case 2; a 24-year-old man, diagnosed with an eating disorder that was later changed to esophageal achalasia. Case 10; a 60-year-old woman’s diagnosis changed from conversion disorder to localized muscle atrophy. Case 19; a 68-year-old man, appetite loss from depression due to cancer changed to secondary adrenal insufficiency, isolated ACTH deficiency (IAD).

Conclusion

This study showed that multiple factors related to misdiagnoses were combined and had a mutual influence. However, they can be summarized into two important clinical observations, diagnostic system-related problems and provider issues. Provider issues contain mainly cognitive biases such as Anchoring, Availability, Confirmation bias, Delayed diagnosis, and Representativeness. In order to avoid diagnostic errors, both a diagnostic system approach and the reduction of cognitive biases are needed. Psychosomatic medicine doctors should pay more attention to physical symptoms and systemic examination and can play an important role in accepting a perception of patients based on a good, non prejudicial patient/physician relationship.

doi: 10.1111/j.1741‐2358.2012.00629.x Langerhans’s cell histiocytosis in old subjects: two rare case reports and review of the literature Background: Langerhans cell histiocytosis (LCH) is a proliferative disease of histiocyte‐like cells that generally affects children; LCH onset is rare in adults; immunohistochemistry is essential to obtain the correct diagnosis, and treatment protocols are controversial. Objective: To describe two new cases of adult onset oral LCH. Case reports: Case 1: a 71‐year‐old woman, complaining of diffuse oral pain, presented with erythematous mucosal lesions; the panoramic radiograph and CT scan showed multiple mandible radiolucent areas. Immunohistochemical assay for S‐100, CD1a and langerin test was essential in reaching the correct diagnosis. Case 2: a 77‐year‐old female patient presented with a non‐painful, non‐bleeding, slightly elevated erythematous palatal lesion of 6 months duration, together with a genital vulvar lesion of uncertain nature. The pathology confirmed the diagnosis of LCH. Many therapies (etoposid, radiotherapy) could induce only a clinical partial remission; Cladribine induced a complete recovery. Conclusion: The first case was difficult to diagnose: the clinical presentation and course of the disease (LCH) in the elderly are multiple and unpredictable. An immunohistochemistry study is often essential to obtain the correct diagnosis. The second case required several therapeutic interventions: even though some cases regress spontaneously, others require systemic chemotherapy.  相似文献

The DF-4 is a new defibrillator lead technology. We present two cases of non-physiological transient ventricular over-sensing in patients who underwent implantation of an ICD for secondary prevention. Case 1 had ventricular over-sensing during pacing threshold evaluation post defibrillation testing while Case 2 had the lead integrity alert triggered immediately post discharge with transient over-sensing. No lead-connector issues were found. Case 1 was likely due to improper venting of the header and trapped air. Case 2 was hypothesized to be due to intermittent header pin non-contact secondary to blood in the header. These cases reveal that DF-4 leads are subject to both reported and potentially novel causes of transient acute ventricular over-sensing.  相似文献

BackgroundProviding benefits and payments to participants in health research, either in cash or in kind, is a common but ethically controversial practice. While much literature has concentrated on appropriate levels of benefits or payments, this paper focuses on less well explored ethical issues around the nature of study benefits, drawing on views of community members living close to an international health research centre in Kenya.MethodsThe consultation, including 90 residents purposively chosen to reflect diversity, used a two-stage deliberative process. Five half-day workshops were each followed by between two and four small group discussions, within a two week period (total 16 groups). During workshops and small groups, facilitators used participatory methods to share information, and promote reflection and debate on ethical issues around types of benefits, including cash, goods, medical and community benefits. Data from workshop and field notes, and voice recordings of small group discussions, were managed using Nvivo 10 and analysed using a Framework Analysis approach.

Findings and Conclusions

The methods generated in-depth discussion with high levels of engagement. Particularly for the most-poor, under-compensation of time in research carries risks of serious harm. Cash payments may best support compensation of costs experienced; while highly valued, goods and medical benefits may be more appropriate as an ‘appreciation’ or incentive for participation. Community benefits were seen as important in supporting but not replacing individual-level benefits, and in building trust in researcher-community relations. Cash payments were seen to have higher risks of undue inducement, commercialising relationships and generating family conflicts than other benefits, particularly where payments are high. Researchers should consider and account for burdens families may experience when children are involved in research. Careful context-specific research planning and skilled and consistent communication about study benefits and payments are important, including in mitigating potential negative effects.  相似文献

A review of psychosocial outcomes for patients seeking cosmetic surgery   总被引:7,自引:0,他引:7  
The authors reviewed the literature on psychological and psychosocial outcomes for individuals undergoing cosmetic surgery, to address whether elective cosmetic procedures improve psychological well-being and psychosocial functioning and whether there are identifiable predictors of an unsatisfactory psychological outcome. They conducted a search of appropriate computerized databases for studies that evaluated psychological and psychosocial status both before and after elective cosmetic surgery. They identified 37 relevant studies of varying cosmetic procedures that utilized disparate methodologies. Overall, patients appeared generally satisfied with the outcome of their procedures, although some exhibited transient and some exhibited longer-lasting psychological disturbance. Factors associated with poor psychosocial outcome included being young, being male, having unrealistic expectations of the procedure, previous unsatisfactory cosmetic surgery, minimal deformity, motivation based on relationship issues, and a history of depression, anxiety, or personality disorder. Body dysmorphic disorder was also recognized by some studies as a predictor of poor outcome, a finding reinforced by reference to the psychiatric literature. The authors conclude that although most people appear satisfied with the outcome of cosmetic surgical procedures, some are not, and attempts should be made to screen for such individuals in cosmetic surgery settings.  相似文献

Life cycle sustainability assessment (LCSA) can be used as a tool to understand how products and operating systems can meet the United Nations’ Sustainable Development Goals (SDGs). However, existing linkages between SDGs and LCSA are limited and an analysis of coverage in literature is needed. In this paper, we propose a generic methodological framework establishing connections between LCSA categories at micro-level and SDGs at macro-level based on derivation from the literature. The qualitative heuristic research method developed builds on keyword literature search, bibliometric analysis, mapping, and narrative literature review for connection rationales. By using qualitative assessment levels, an assessment of linkages between LCSA categories and SDGs reveal that “technology development,” “public commitment to sustainability issues,” “access to material resources,” and “education provided in the local community” have the highest number of reported relationships with SDGs. Twenty-two LCSA categories were found with no direct/indirect connection with any SDG; reasons include absence of life cycle thinking perspective in SDGs and lack of sustainability-based discussion for workers, consumers, and value chain actors' stakeholder groups. Despite these gaps, the results provide new insights for industries looking to measure the contribution of their product systems along their life cycle in the context of SDGs supporting them to some extent, to select LCSA categories with either highest number of identified relationships to SDGs or that contribute to prioritized list of SDGs. The approach provides a starting point to improve transparency and consistency of reporting of sustainability performance of product systems by connecting LCSA to the global agenda for sustainable development.  相似文献

Genetic Education for Native Americans (GENA) was a National Human Genome Research Institute (NHGRI)/Ethical, Legal, and Social Implications (ELSI)-funded educational intervention designed to provide a unique genetics education program for Native American college and university students. A curriculum was developed and implemented in workshops in geographically diverse settings throughout the United States, primarily in conjunction with regional and national scientific conferences that include substantial numbers of Native American attendees. The original curriculum includes 24 objectives and has been offered in two formats, as a 16-hr "comprehensive" program and in briefer workshops (referred to as "customized" hereafter) that are designed to include objectives for selected audiences. Both formats teach sufficient genetics to allow discussion and understanding of the ELSI and cultural issues related to genetics science. This article describes the evaluation findings from our implementation of both formats of the GENA curriculum.  相似文献

Complete or partial facial duplication is a rare congenital malformation. A spectrum of structural abnormalities varying in degrees of severity has been described in affected individuals. We present discordance for facial duplication between monozygotic twins in which maxillary and mandibular duplication was present in one. The involved twin showed the following findings: ocular hypertelorism, bifidity of the nose, duplication of the maxilla, macrostomia, cleft of the lower lip, hamartoma of the vomer, supernumerary teeth, duplication of the mandibular teeth, bifidity of the tongue, and hamartoma of the floor of the mouth. Surgical management of the facial anomalies is discussed. A review of the literature and discussion of this rare malformation are presented.  相似文献

Idiopathic CD4 lymphocytopenia (ICL) is a presumed heterogenous syndrome with key element low CD4 T-cell counts (below 300/mm3) without evidence of HIV infection or other known immunodeficiency. The etiology, pathogenesis, and management of ICL remain poorly understood and inadequately defined. The clinical presentation can range from serious opportunistic infections to incidentally diagnosed asymptomatic individuals. Cryptococcal and non-tuberculous mycobacterial infections and progressive multifocal leukoencephalopathy are the most significant presenting infections, although the spectrum of opportunistic diseases can be similar to that in patients with lymphopenia and HIV infection. Malignancy is common and related to opportunistic pathogens with an oncogenic potential. Autoimmune diseases are also seen in ICL with an increased incidence. The etiology of ICL is unknown. Mechanisms implicated in CD4 reduction may include decreased production, increased destruction, and tissue sequestration. New distinct genetic defects have been identified in certain patients with ICL, supporting the hypothesis of the lack of a common etiology in this syndrome. The management of ICL is focused on the treatment of opportunistic infections, appropriate prophylactic antibiotics, and close monitoring. In selected patients with life-threatening infections or profound immunodeficiency, strategies to increase T-cell counts or enhance immune function could be considered and have included interleukin-2, interferon-gamma, interleukin-7, and hematopoietic stem cell transplantation. The prognosis is influenced by the accompanying opportunistic infections and may be affected by publication bias of severe cases with unfavorable outcomes. As newer laboratory investigation techniques are being developed and targeted experimental treatments become available, our comprehension and prognosis of this rare syndrome could be significantly improved.Idiopathic CD4 lymphocytopenia (ICL) was described in 1992 as an immunodeficiency syndrome characterized by opportunistic infections and low CD4 T-cell counts in the absence of HIV infection. Despite the 20 years that have elapsed, the clinical spectrum, pathogenesis, and possible treatment for ICL remain obscure. Here, we attempt to summarize the salient features of this condition on the basis of the available literature to date.  相似文献

Energy crops on marginal lands are seen as an interesting option to increase biomass contribution to the primary energy mix. However, in the literature there is currently a lack of integrated assessments of margin land availability, energy crop production potential and supply chain optimisation. Assessing the potential and the cost of these resources in a given region is therefore a difficult task. This work also emphasises the importance on a clear definition and discussion about marginal lands and the related ethical issues embedded in the concept to ensure positive societal impacts of the results. This study proposes a methodology to estimate and analyse, in terms of economic costs, the potential of miscanthus grown on marginal lands from the production to the final point of use. Different datasets are assembled and a supply chain optimisation model is developed to minimize the total cost of the system. Miscanthus is used as a representative energy crop for the Belgian and French case studies. High temperature heat demand is considered as final use. The miscanthus can be traded by truck either in the form of chips or pellets. The results show that the miscanthus on marginal lands could supply high temperature heat up to 38 TWh in France and 1.4 TWh in Belgium with an average cost of around 50 €/t. The different sensitivity analyses showed that the yield variation has the strongest influence on the final cost, together with the distances and the cost of production of miscanthus. The main pattern observed is the local consumption of miscanthus chips and export of the surplus (if any) to the neighbouring regions. Pellets are only of marginal interest for France and are never observed for Belgium. Distances and availability of sufficient feedstocks are the two main parameters impacting the production of pellets.  相似文献

The conference was organized in part to dispel some of the misinformation that interferes with cooperative efforts of attorneys and physicians to redress the malpractice situation. During discussion of the hypothetical case, participants identified how medical decision-making responsibilities were allocated among health care providers caring for the patient. Panel members suggested ways in which medical decision making might be affected by non-medical factors such as third-party reimbursement (e.g., selection of inpatient or outpatient setting, the opportunity to discuss issues related to informed consent prior to the day of a procedure) and potential malpractice litigation (e.g., documentation in charts, use of diagnostic procedures). The characterization of decision-making roles and responsibilities differed somewhat for purposes of malpractice litigation; that is, which caregivers might be named as defendants. Panel members reconstructed the development of the medical incident into a legal case. Plaintiff's attorney commented that it is often a hospital employee who advises the family to consult an attorney and described some of the constraints on information gathering (e.g., the rule of "discovery" requiring that suit be filed before defendants can be forced to give statements about what happened, insurance contract provisions prohibiting physicians from talking without legal counsel present to persons who indicate that they plan to file suit). He also briefly explained the rationale for the contingency fee arrangement in these cases. Describing the role of the medical expert witness and the need to review the medical record, he outlined the process of deciding whether to pursue a malpractice case. In making this decision, plaintiff's attorney evaluates the facts to identify issues in the case, to determine if there are deviations from the standard of care, and to try to predict jury reaction. If a suit is filed, defense attorneys employed by the hospital, insurance company, or individual defendants will decide, based on facts including coverage limits, possible publicity, and likelihood of successful prosecution, whether the case should be settled and for what amount. Interests represented by the defense attorneys differ and may affect settlement strategies. Physician feelings of concern for the patient/family or desire for vindication will, to varying degrees, be factors in the decision to try or settle a case. Panel members explored several important policy issues. Among these were the effect of malpractice cases on doctor-patient communications and ethical issues concerning expert witnesses.(ABSTRACT TRUNCATED AT 400 WORDS)  相似文献

The introduction of new tools for molecular analysis, such as RT-qPCR and microarrays, has provided researchers with powerful applications to study renal disease and development. However, the high cellular heterogeneity of the renal tissue complicates the molecular analysis of specific cells and cell groups such as glomerular or tubular cells. In the past, glomerular sieving and manual dissection were used for the isolation of glomeruli. However, these techniques cannot be used for the isolation of specific glomeruli or for the co-isolation of additional tissue fractions. In recent decades, new microdissection techniques such as laser-assisted microdissection have been developed. These applications allow the isolation of small cell groups from heterogeneous tissue for molecular analysis, including microarray and RT-qPCR. Although very promising, some drawbacks are associated with these techniques. The isolated sample material is generally small and requires sensitive assays. In addition, the long sample processing time may result in a considerable loss of RNA integrity. Careful optimization and rigorous quality analysis should overcome these drawbacks. In the present paper, the recent literature on the application of microdissection techniques in kidney research is reviewed, together with a discussion of the critical issues that are essential for the application of quantitative mRNA expression analysis with RT-qPCR on microdissected samples.  相似文献
