The Investigation of Events that followed the death of Cyril Mark Isaacs

CHAPTER 36

The retention of brains for teaching

Introduction

This investigation is primarily concerned with the retention of brains for research after post mortems ordered by the Coroner, but brains were also retained for teaching purposes.
Sources of information
This chapter is based on contemporaneous records from Sheffield and Manchester Universities and the recollections of those involved.

History

In the 1950s most medical students dissected the brain as part of their anatomy course. For these courses large numbers of brains were obtained from both hospital and Coroners' post mortems.

Human Tissue Act 1961

Following the enactment of the Human Tissue Act in 1961 it should have been routine for relatives to be asked if they had objections before any brain was retained for medical education. In order to continue brain dissection, some medical schools introduced post mortem consent forms that referred specifically to retention of tissues for medical education.

The Medico Legal Centre and the Anatomy Department of Sheffield University

An incident at Sheffield Medico Legal Centre in December 1986 brought the retention of brains for medical education to public notice. The following paragraphs describe this incident which was widely reported in the local and national media at the time. A full investigation was carried out by Sheffield City Council, and a debate in the Council chamber followed. This closed the incident.

December 1986

Just before Christmas 1986, a telephone call was received by the manager of the Medico Legal Centre from the Department of Anatomy at Sheffield University.
The manager, who had recently been appointed, was surprised to receive a request for a further supply of brains for teaching medical undergraduates.
The caller from the Anatomy Department was put through to the Coroner's Officer, who then informed the Coroner, Dr Popper, who was concerned to know whether consent had been given.
The manager of the Medico Legal Centre also informed Sheffield City Council headquarters as the Council had responsibility for the Centre which serves as the public mortuary for the whole city.

The Coroner's investigation

Dr Popper made immediate enquiries. These revealed that in 1983 his predecessor as Coroner, the late Dr Pilling, had agreed to the removal of heart valves for transplantation from bodies under his jurisdiction but only with the written consent of the relatives of the deceased.
Dr Pilling had also agreed that the Department of Anatomy could receive blocks of tissue to make slides for teaching purposes, but only from those bodies for which the relatives had given consent for heart valves to be removed.
At some stage between 1983 and December 1986 the terms of Dr Pilling's agreement had been extended from the supply of blocks and tissue for slides to include whole brains. This had not been Dr Pilling's intention.

January 1987

Staff of Sheffield City Council arranged a meeting on 9 January to investigate 'the apparent unauthorised removal of organs during post mortems and organs being sent to the University'. The City Council were particularly concerned by the suggestion that mortuary staff were receiving payments for brains transferred to the Anatomy Department. This was in clear breach of the Council's policy.
At that meeting Dr Popper reminded those present that 'removal of human tissue may only be done under the provisions of the Human Tissue Act'.
Dr Popper stated that, as Coroner, he was 'not aware of the removal of any organs or tissues, except the heart valves which his predecessor had allowed to be removed with the consent of the relatives. The only other tissue or organs that could be removed were those required for the purpose of establishing the cause of death'(1).
Professor Usher, Professor of Forensic Pathology at Sheffield, is recorded as saying: 'All practices are traditional and the inherited situation, which had been long-standing between the Chief Technician of Anatomy at Sheffield University and the Senior Technician in the Public Mortuary …'(1).

Action taken

Dr Popper gave immediate instructions that: 'He would not agree to the removal of organs without consents, but would approve of any agreed system, which could be devised within the law'(2).
He ordered that all transfers of brains should cease and wrote to all pathologists to say that: 'No tissue was to be taken without consent'.

20 January 1987

The Sheffield Star reported the brain transfers on the front page. There was further publicity in the national media.
The City Council's investigation proceeded. A full report was prepared which was submitted to and debated by the City Council.
Since January 1987, Dr Popper and Mr Dorries, who succeeded him as Coroner for Sheffield in 1991, have followed a policy that no organs or tissues should be retained without the consent of relatives. The only exception to this rule is the retention of those organs or tissues that are needed for diagnostic purposes and the examination of which will bear on the cause of death.
Further investigations were started to discover how many brains from Coroners' autopsies had been transferred from the Medico Legal Centre to the Anatomy Department at the University, and over what period of time, but this information was not forthcoming.

Wider implications

When the irregular and unconsented transfer of brains from the Medico Legal Centre to the Department of Anatomy was discovered, the late Dr Paul Mason, who was then HM Inspector of Anatomy, was informed. On 27 January 1987 Dr Mason wrote to anatomy departments to tell them to review the arrangements through which they obtained brains for teaching and to ensure that these arrangements complied with the Human Tissue Act.

Anatomy Department of Manchester Medical School

In reply to Dr Mason's letter, Professor P F Harris, Professor of Anatomy, drew attention to the arrangements he had introduced in the 1970s. All brains obtained by his department for medical education were collected with the consent of the relatives.
Professor Harris' letter, which by coincidence was written on 27 February 1987 (the day after Mr Isaacs' death), states: 'We have two sources of supply to the Manchester Medical School and in both instances the position is very clearly covered by the wording on the postmortem declaration form which is signed by a relative. Our established practice has worked well over many years'.
In fact, the practice had been in operation for the previous 12 years.
The post mortem declaration form includes the words: 'I understand that this examination is carried out (a) to verify the cause of death …' and '(b) to remove amounts of tissue for the treatment of other patients and for medical education and research'.
The consent form clearly states that the relative could, if they so wished, delete paragraph (a) or (b). The relative's signature on the form was required to be witnessed.
The form includes a further note: 'A relative of the deceased should not be invited to sign this form if the hospital is itself aware of objections on the part of other relatives'.

Brains collected by anatomy departments

I have made enquires in other anatomy departments to see if any records remain available of brains collected for medical education. I have not been able to identify any extant records.
A significant factor in the ending of brain dissection by medical students was the recognition in 1992 that Creutzfeldt Jacob disease could be transmitted by contact with brain tissue. A direct result of this discovery was the removal of brain dissection from the curriculum by those medical schools that had maintained brain dissection up to that time.

Summary

Before the Human Tissue Act 1961 it was common practice for medical schools to obtain brains for teaching purposes from hospital and Coroners' post mortems.
The use of brains in medical education continued largely unchanged through the 1960s but thereafter diminished, although in some locations brain dissection continued until the early 1990s.
In the 1970s Manchester University Medical School introduced a consent form for tissue retention for research and education, for relatives to sign. Though not explicit, the form was considered as providing consent for brain retention. No brains were accepted for teaching purposes in Manchester unless this consent form had been signed.
The incident at the Medico Legal Centre in Sheffield in December 1986 showed that brain retention for medical education was continuing without the knowledge or consent of the relatives and outwith the requirements of the law.
Steps were taken by HM Inspector of Anatomy in 1987 to remind all anatomy departments that brains (and other organs) must not be used for teaching purposes without the consent of the relatives.
Anatomy departments are required by the Anatomy Regulations 1988 to keep records of the body parts they hold. The records of individual brains now held in anatomy departments in England do not identify the deceased or when and where the brain was retained.
