Doctor who gave expert advice in "shaken baby" cases is struck off.
BMJ, 2016Co-Authors: Clare DyerAbstract:A leading paediatric Neuropathologist has been struck off the United Kingdom’s medical register for repeatedly giving misleading and dishonest evidence to the courts in so called “shaken baby” cases. Waney Squier, 68, from the John Radcliffe Hospital in Oxford, was a frequent expert witness for parents accused of injuring or killing their babies by deliberate acts. She raised the possibility of different causes, such as choking, for injuries that other experts attributed to abusive head trauma. The medical practitioners’ tribunal gave Squier credit for her “eminent work as a Neuropathologist of national and international standing” and acknowledged testimonials declaring that she had been “scrupulously honest” in her work outside the court environment. The …

Shaken baby witness was dishonest about her expertise, finds tribunal
BMJ, 2016Co-Authors: Clare DyerAbstract:A leading expert witness who gave evidence for parents in alleged “shaken baby” cases was dishonest in acting outside her expertise and in deliberately misrepresenting the research literature, a medical practitioners’ tribunal has ruled. Waney Squier, a consultant Neuropathologist since 1984, changed her opinion on the mechanisms of abusive head trauma after the publication of hypotheses by the clinical Neuropathologist Jennian Geddes,1 said the tribunal chair, Michele Codd. The tribunal found that, in Squier’s written and oral evidence to courts, she was “dogmatic, inflexible, and unreceptive to any other view” and that she “cherry picked” the literature to support her argument …

child death expert provided misleading and biased evidence panel hears
BMJ, 2015Co-Authors: Clare DyerAbstract:A senior paediatric Neuropathologist adopted a “preconceived and blinkered approach” when appearing as an expert witness in six “shaken baby” court cases, a fitness to practise panel heard this week. The UK’s General Medical Council (GMC) has accused Waney Squier, who worked as a consultant at the John Radcliffe Hospital in Oxford, of acting outside her competence, failing to take account of other experts’ views, and misleadingly citing research that did not in fact support her conclusions. She denies the allegations. Squier, 67, is also accused of providing an expert report for an appeal without disclosing that GMC …

shaken baby expert must disclose fitness to practise charges when asked to give evidence in new cases
BMJ, 2015Co-Authors: Clare DyerAbstract:A leading UK Neuropathologist and expert witness in shaken baby cases must tell anyone who commissions her to prepare an expert report that she is facing fitness to practise charges, under conditions imposed on her medical registration. The decision to impose interim conditions on Waney Squier’s registration was made by the Medical Practitioners Tribunal Service after the disclosure that she failed to mention her upcoming hearing when agreeing in April 2014 to …

Pathologist complains to BBC and Ofcom about her portrayal in television drama.
BMJ, 2012Co-Authors: Clare DyerAbstract:Waney Squier, a consultant paediatric Neuropathologist seen as being in the “sceptic” camp on shaken baby syndrome, has filed complaints with the British Broadcasting Corporation and the UK media regulator Ofcom over the portrayal of a rogue pathologist in a television drama series that she says has damaged her reputation. Squier believes that the fictional paediatric Neuropathologist Helen Karamides in a two part episode of Silent Witness broadcast in April is based on her. Karamides, a sceptic about shaken baby syndrome, is portrayed as a doctor who makes wrong diagnoses, retains children’s brains for her own research, is …

what every Neuropathologist needs to know update on cimpact now
Journal of Neuropathology and Experimental Neurology, 2019Co-Authors: Gabrielle Yeaney, Daniel J BratAbstract:: World Health Organization (WHO) central nervous system tumor classification represents the primary source of updates on diagnostic classes, grades, and criteria. However, recent and ongoing advances in molecular pathogenesis warrant more rapid integration into clinical practice between WHO updates. To accomplish this, the consortium to inform molecular and practical approaches to CNS tumor taxonomy-not official WHO (cIMPACT-NOW) was established in 2016. Since then, cIMPACT-NOW has convened 3 separate working committees to address classification and grading questions and challenges. This review covers the progress that these working committees have made on their specific topics.

cimpact now the consortium to inform molecular and practical approaches to cns tumor taxonomy a new initiative in advancing nervous system tumor classification
Brain Pathology, 2017Co-Authors: David N Louis, Kenneth D Aldape, Daniel J Brat, David Capper, David W Ellison, Cynthia Hawkins, Werner Paulus, Arie Perry, Guido Reifenberger, Dominique FigarellabrangerAbstract:The 2016 World Health Organization Classification of Tumors of the Central Nervous System (2016 CNS WHO) is a major shift in the way Neuropathologists analyze and diagnose brain tumors as it incorporates molecular and histological information together to define many entities (1). While the 2016 CNS WHO thereby facilitates more precise diagnosis of well-understood entities and clearer designation of less-understood entities, it also presents a number of practical challenges for Neuropathologists, requiring substantial shifts in their day-to-day practices (2). Nonetheless, Neuropathologiste will learn the system readily over time, and will adapt as needed to the new requirements.

Pathology of peripheral nerve sheath tumors: diagnostic overview and update on selected diagnostic problems
Acta Neuropathologica, 2012Co-Authors: Fausto J. Rodriguez, Caterina Giannini, Andrew L. Folpe, Arie PerryAbstract:Peripheral nerve sheath tumors are common neoplasms, with classic identifiable features, but on occasion, they are diagnostically challenging. Although well-defined subtypes of peripheral nerve sheath tumors were described early in the history of surgical pathology, controversies regarding the classification and grading of these tumors persist. Advances in molecular biology have provided new insights into the nature of the various peripheral nerve sheath tumors, and have begun to suggest novel targeted therapeutic approaches. In this review, we discuss current concepts and problematic areas in the pathology of peripheral nerve sheath tumors. Diagnostic criteria and differential diagnosis for the major categories of nerve sheath tumors are proposed, including neurofibroma, schwannoma, and perineurioma. Diagnostically challenging variants, including plexiform, cellular and melanotic schwannomas are highlighted. A subset of these affects the childhood population, and has historically been interpreted as malignant, although current evidence and outcome data suggest they represent benign entities. The growing current literature and the author's experience with difficult to classify borderline or “hybrid tumors” are discussed and illustrated. Some of these classification gray zones occur with frequency in the gastrointestinal tract, an anatomical compartment that must always be entertained when examining these neoplasms. Other growing recent areas of interest include the heterogeneous group of pseudoneoplastic lesions involving peripheral nerve composed of mature adipose tissue and/or skeletal muscle, such as the enigmatic neuromuscular choristoma. Malignant peripheral nerve sheath tumors (MPNST) represent a diagnostically controversial group; difficulties in grading and guidelines to separate “atypical neurofibroma” from MPNST are provided. There is an increasing literature of MPNST mimics which Neuropathologists must be aware of, including synovial sarcoma and ossifying fibromyxoid tumor. Finally, we discuss entities that are lacking from the section on cranial and paraspinal nerves in the current WHO classification, and that may warrant inclusion in future classifications. In summary, although the diagnosis and classification of most conventional peripheral nerve sheath tumors are relatively straightforward for the experienced observer, yet borderline and difficult-to-classify neoplasms continue to be problematic. In the current review, we attempt to provide some useful guidelines for the surgical Neuropathologist to help navigate these persistent, challenging problems.

what every Neuropathologist needs to know neuropathology and the us legal system
Journal of Neuropathology and Experimental Neurology, 2019Co-Authors: Jesse Kresak, Sharon Zehe, Ross R ReichardAbstract:: The legal system of the United States is complex, with nuances that are particular to its many jurisdictions. The Neuropathologist may professionally interact with the legal system in both criminal and civil proceedings as either a fact or expert witness, and in rare instances as a defendant. The nature of the legal issue at hand will define the pathologist's role and determine what actions are required or requested. The intersection of neuropathology and the laws governing quality assurance may be less defined as legal statutes vary by state; although, the general principles of privilege, peer review, and confidentiality remain similar. Aside from a forensic pathology fellowship, there is often little in the way of our training to prepare us for our potential roles in the courtroom. This article serves as a review for the Neuropathologist's role as a witness, the legal proceedings that you may participate in, and the intersection between quality assurance and law.

Autopsy services for old age psychiatrists in england and wales: Can Neuropathologists help?
International Journal of Geriatric Psychiatry, 1995Co-Authors: Emyr W. Benbow, Helen Reid, Susan M. BenbowAbstract:We have previously shown that many old age psychiatrists are dissatisfied with their local autopsy services. Their most common complaint was the poor quality of central nervous system examinations carried out by general histopathologists, and so we sought to determine whether Neuropathologists could carry out more autopsies on old age psychiatry patients. A postal questionnaire was used, and responses indicate that Neuropathologists carry out an average of 8.8 autopsies on old age psychiatry patients each year, out of a mean total of 42.2 neuropathological autopsies, and examine an average of 28.3 other brains from old age psychiatry patients, out of a mean total of 109.3 cases. In general, respondents found autopsies on psychiatric and neurological patients much more interesting than autopsies on neurosurgical and forensic cases, but did not rate psychiatric autopsies as more important than any other kind of case. Most Neuropathologists would wish to examine more brains from old age psychiatry patients, but would require more pathologists, more technicians or more resources before doing so. Old age psychiatrists who wish to obtain a better autopsy service may need to take the initiative.

Autopsy services for old age psychiatrists in England and Wales: A survey of consumer satisfaction
International Journal of Geriatric Psychiatry, 1994Co-Authors: Emyr W. Benbow, Susan M. Benbow, Helen ReidAbstract:Anecdotal evidence suggests that some old age psychiatrists are dissatisfied and disillusioned with their local autopsy services, and so we carried out a postal survey to assess the extent of the problem. Our most striking finding was that over a quarter of old age psychiatrists are, indeed, dissatisfied with the way other organ systems were examined. This dissatisfaction is very strongly associated with services where autopsies on psychogeriatric patients are carried out by general histopathologists, especially where there is no established facility for the brain to be preserved and subsequently examined by a Neuropathologist. The main complaint about Neuropathologists was that reports sometimes took an unacceptable length of time to be returned to the clinician. The solution to the difficulties experienced by old age psychiatrists would be a closer association with their local neuropathology services, but whether Neuropathologists are in a position to increase their workloads remains to be determined.

Autopsy services for old age psychiatrists in england and wales: Benefits and problems
International Journal of Geriatric Psychiatry, 1994Co-Authors: Emyr W. Benbow, Susan M. BenbowAbstract:We sought to determine the views of old age psychiatrists about the quality, benefits and drawbacks of their autopsy services, so a postal questionnaire was circulated to all individuals identified by the Royal College of Psychiatrists as providing old age psychiatry services in England and Wales. We found that many old age psychiatrists are aware of the potential benefits of autopsies, but many receive a service which is of poor quality. Some have difficulty in organizing hospital autopsies, and many found coroners' autopsies unhelpful, with the brain being ignored or examined only superficially. Poor descriptions of neuropathology are associated with autopsies carried out by general histopathologists, whereas Neuropathologists are criticized for delayed reports. Better services might be provided if Neuropathologists could be more closely involved, if only in the examination of brains removed by other pathologists.
