The Witness Seminar is a specialized form of oral history, where several individuals associated with a particular set of circumstances or events are invited to meet together to discuss, debate, and agree or disagree about their memories. The meeting is recorded, transcribed and edited for publication. This format was first devised and used by the Wellcome Trust’s History of Twentieth Century Medicine Group in 1993 to address issues associated with the discovery of monoclonal antibodies. We developed this approach after holding a conventional seminar, given by a medical historian, on the discovery of interferon. Many members of the invited audience were scientists or others involved in that work, and the detailed and revealing discussion session afterwards alerted us to the importance of recording ‘communal’ eyewitness testimonies. We learned that the Institute for Contemporary British History held meetings to examine modern political, diplomatic and economic history, which they called Witness Seminars, and this seemed a suitable title for us to use also. The unexpected success of our first Witness Seminar, as assessed by the willingness of the participants to attend, speak frankly, agree and disagree, and also by many requests for its transcript, encouraged us to develop the Witness Seminar model into a full programme, and since then more than 50 meetings have been held and published on a wide array of biomedical topics.1 These seminars have proved an ideal way to bring together clinicians, scientists, and others interested in contemporary medical history to share their memories. We are not seeking a consensus, but are providing the opportunity to hear an array of voices, many little known, of individuals who were ‘there at the time’ and thus able to question, ratify or disagree with others’ accounts – a form of open peer-review. The material records of the meeting also create archival sources for present and future use. The History of Twentieth Century Medicine Group became a part of the Wellcome Trust’s Centre for the History of Medicine at UCL in October 2000 until September 2010. It has been part of the School of History, Queen Mary, University of London, since October 2010, as the History of Modern Biomedicine Research Group, which the Wellcome Trust funds principally 1 See pages 203–208 for a full list of Witness Seminars held, details of the published volumes and other related publications. v under a Strategic Award entitled ‘The Makers of Modern Biomedicine’. The Witness Seminar format continues to be a major part of that programme, although now the subjects are largely focused on areas of strategic importance to the Wellcome Trust, including the neurosciences, clinical genetics, and medical technology.2 Once an appropriate topic has been agreed, usually after discussion with a specialist adviser, suitable participants are identified and invited. As the organization of the seminar progresses and the participants’ list is compiled, a flexible outline plan for the meeting is devised, with assistance from the meeting’s designated chairman/moderator. Each participant is sent an attendance list and a copy of this programme before the meeting. Seminars last for about four hours; occasionally full-day meetings have been held. After each meeting the raw transcript is sent to every participant, each of whom is asked to check his or her own contribution and to provide brief biographical details for an appendix. The editors incorporate participants’ minor corrections and turn the transcript into readable text, with footnotes, appendices and a bibliography. Extensive research and liaison with the participants is conducted to produce the final script, which is then sent to every contributor for approval and to assign copyright to the Wellcome Trust. Copies of the original, and edited, transcripts and additional correspondence generated by the editorial process are all deposited with the records of each meeting in the Wellcome Library, London (archival reference GC/253) and are available for study. For all our volumes, we hope that, even if the precise details of the more technical sections are not clear to the non-specialist, the sense and significance of the events will be understandable to all readers. Our aim is that the volumes inform those with a general interest in the history of modern medicine and medical science; provide historians with new insights, fresh material for study, and further themes for research; and emphasize to the participants that their own working lives are of proper and necessary concern to historians. 2 See our Group’s website at http://www.history.qmul.ac.uk/research/modbiomed (visited 13 August 2013). vi ACKNowlEDGEMENTS The topic of ‘Drugs affecting 5-HT systems’ was suggested as a Witness Seminar by Professor Paul Andrews and Professor Gareth Sanger and we are grateful for their assistance over several months in planning the meeting. Our thanks also go to Professor Rod Flower for his excellent chairing of the occasion, and to Dr Patrick Humphrey for providing images and documents to illustrate the volume. As with all our meetings, we depend a great deal on Wellcome Trust staff to ensure their smooth running: the Audiovisual Department, Catering, Reception, Security and Wellcome Images. We are also grateful to Mr Akio Morishima for the design and production of this volume; the indexer Ms Liza Furnival; Mrs Lois Reynolds and Ms Fiona Plowman for proof reading; Mrs Deborah Gee for transcribing the seminar; Mr Adam Wilkinson for assisting in the organization of the meeting and also Ms Emma Jones and Mr Alan Yabsley for help with running the seminar. Finally, we thank the Wellcome Trust for supporting this programme.

  • Interview with Pierre Pichot
    PSYCHOPHARMACOLOGY AND THE HISTORY OF PSYCHIATRY PIERRE PICHOT Could we begin with your recollections of the 1955 Paris meeting, which was effectively the first world wide meeting on chlorpromazine. The meeting was organised in Paris by Jean Delay. It was supported by Specia, the pharmaceutical firm which had produced chlorpromazine, which was a branch of the Rhone Poulenc Group. For the first time people engaged in what was called psychopharmacology came together. They came from many countries, including the United States. The efficacy of the drug and the mechanism of action were discussed. However, at that time the biochemistry of the brain, as it exists now, was unknown. It was only at the beginning of the 60s, that we began to speak of the role of the neurotransmitters in the action of both neuroleptic drugs and antidepressants and of their potential abnormalities in the disease process. So in practice 1955 was only a meeting on therapy with chlorpromazine. I have always been very much impressed by the fact that chlorpromazine, which had been introduced only 3 years before, was already used all over the world. Theoretical ideas take usually a very long time to travel from one country to another, and sometimes they never make it. I quote always, the case of Karl Jaspers’ General Psychopathology, which is considered in the German speaking world as one of the basic books of psychiatry. This was published in 1913 but appeared in English translation only in 1963, 50 years later and, even then, a paper published in the American Journal of Psychiatry wrote ingenuously that, until this publication, many psychiatrists in the United States had not realised that Jaspers was not only a philosopher, but also a psychiatrist.

  • New Developments in Prokinetic Therapy for Gastric Motility Disorders
    REVIEW published: 24 August 2021 doi: 10.3389/fphar.2021.711500 New Developments in Prokinetic Therapy for Gastric Motility Disorders Michael Camilleri* and Jessica Atieh Clinical Enteric Neuroscience Translational and Epidemiological Research (CENTER), Division of Gastroenterology and Hepatology, Mayo Clinic, Rochester, MN, United States Prokinetic agents amplify and coordinate the gastrointestinal muscular contractions to facilitate the transit of intra-luminal content. Following the institution of dietary recommendations, prokinetics are the first medications whose goal is to improve gastric emptying and relieve symptoms of gastroparesis. The recommended use of metoclopramide, the only currently approved medication for gastroparesis in the United States, is for a duration of less than 3 months, due to the risk of reversible or irreversible extrapyramidal tremors. Domperidone, a dopamine D2 receptor antagonist, is available for prescription through the FDA’s program for Expanded Access to Investigational Drugs. Macrolides are used off label and are associated with tachyphylaxis and variable duration of efficacy. Aprepitant relieves some symptoms of gastroparesis. There are newer agents in the pipeline targeting diverse gastric (fundic, antral and pyloric) motor functions, including novel serotonergic 5-HT4 agonists, dopaminergic D2/3 antagonists, neurokinin NK1 antagonists, and ghrelin agonist.

That sometimes he cannot sleep at night because he is dreaming of gouache, lithography, pastel, monotype, charcoal, oil, etchings, plates, wax. That he wants to stop and start time at his prerogative so that he can revel in the bounty of materials, van challenge himself and experiment without time passing because the day isn’t long enough. That the circus or the Opera ballet, or the cafe chantants or dinners with friends or the delicious masculine embrace of the racetrack devour his evenings and Sundays but in between there is only work. That some days he looks up and hours have passed and he is late for one thing or another and he races to the cafe or the friends or the theater and what he leaves behind is unfinished work, and he thinks nothing he makes will ever be finished. That he must make careful calculations in order to produce his articles because he is not gifted, he is not prescient, he is not an auteur, he is only a draftsman, a servant, a plodding poseur who wishes to excel. That he is hampered by the infernal blur in his eye he fears will only spread. That the arrangement of legs on a group of dancers or the colour of skirt sashes or the depth of the stage or the bend of a laundress’s back or the line of her apron confounds him and has to be worked and reworked.

  • Comparison of Different Alpha-Blocker Combinations in Male Hypertensives with Refractory Lower Urinary Tract Symptoms
    대한남성과학회지:제 29 권 제 3 호 2011년 12월 Korean J Androl. Vol. 29, No. 3, December 2011 http://dx.doi.org/10.5534/kja.2011.29.3.242 Comparison of Different Alpha-blocker Combinations in Male Hypertensives with Refractory Lower Urinary Tract Symptoms Keon Cheol Lee1, Jong Gu Kim2, Sung Yong Cho1, Joon Sung Jeon1, In Rae Cho1 Department of Urology, 1Inje University Ilsanpaik Hospital, Goyang, 2Happy Urology Clinic, Ansan, Korea =Abstract= Purpose: We compared the efficacy and safety profiles of dose increase, traditional combination methods, and combining different alpha blockers in hypertensive males with lower urinary tract symptom (LUTS) refractory to an initial dose of 4 mg doxazosin. Materials and Methods: Between 2000 and 2005, 374 male patients with LUTS and hypertension unresponsive to 4 weeks of 4 mg doxazosin were enrolled. The subjects were randomly classified into 3 groups, 8 mg/day of doxazosin (D group), 4 mg of doxazosin plus 0.2 mg/day of tamsulosin (DT group), and 4 mg doxazosin plus 5 mg/day finasteride (DF group). Patients were evaluated based on their International Prostate Symptom Score (IPSS), quality of life (QOL), uroflowmetry and blood pressure (BP) and adverse events (AEs) at the baseline and 3 and 12 months after treatment. Results: The 269 patients (71.9%) were followed for at least 1 year (D group n=84, DT group n=115, and DF group n=70). The clinical parameters before and after initial 4 mg/day doxazosin were not different among the 3 groups. IPSS improvement after 3 months and maximal flow rate (Qmax) improvement after 3 and 12 months were significantly higher in the D and DT groups than the DF group (p<0.05).
