Navigating the Strait of Magellan: mapping a new paradigm for neurosurgical residency training. Presidential address to the Society of Neurological Surgeons, May 7, 2007

At the conclusion of his year as 81st president of the Society of Neurological Surgeons, the author delivered the following address at the 2007 annual meeting of the Society of Neurological Surgeons in San Francisco. In his address, Dr. Popp used the voyage of Ferdinand Magellan to illustrate the present climate affecting residency training and why the current training paradigm must be examined and, where necessary, changed. Based on this call to action the leaders of the American Association of Neurological Surgeons, The American Board of Neurological Surgeons, The Congress of Neurological Surgeons, The Council of State Neurosurgical Societies, The Residency Review Committee for Neurosurgery, The Society of Neurological Surgeons, and the Washington Committee for Neurosurgery agreed to hold an unprecedented Education Summit meeting to investigate a comprehensive approach to evaluating and changing the current neurosurgical residency training model.     

NeuroSIG: the computer network of the Congress of Neurological Surgeons

A sophisticated computer network has been developed specifically for use by the Congress of Neurological Surgeons. This network provides a variety of communication and information features. These include public and private message transmission, teleconferencing, numerous data libraries, programs that may be downloaded and executed on the user's own computer, high resolution color graphics image transmission, an extensive neurosurgical database, and extensive on-line "help" features. The system can be accessed using almost any personal computer and a telephone modem.     

Honoring the 75th anniversary of the American Association of Neurological Surgeons. Preface

Ever since the Journal of Neurosurgery (JNS) published its first volume in 1944, the journal has reflected the scientific, technical, and clinical evolution of our specialty and parent organization, first called the Harvey Cushing Society and later the American Association of Neurological Surgeons. The JNS has been an uncompromising arbiter of progress in our specialty, and its superb editorial stewardship has led to its recognition as the premier journal in the field. The impact rating of JNS and its wide circulation among neurosurgeons worldwide are two of the many reasons why most of the truly innovative and paradigm-shifting advances in neurosurgery have been published in its pages. As part of the 75th anniversary of the American Association of Neurological Surgeons celebration, the JNS Publishing Group has initiated a project of reviewing papers published over the years that have had the highest impact factor and greatest scientific interest: papers that have heralded new knowledge, new concepts, and new techniques that have been at the heart of modern neurosurgery and its continuing excitement and progress. We hope you will enjoy these articles and the accompanying commentaries. In this issue we present the next paper in this series.     

The future of neurosurgery: a white paper on the recruitment and retention of women in neurosurgery

PREFACE: The leadership of Women in Neurosurgery (WINS) has been asked by the Board of Directors of the American Association of Neurological Surgeons (AANS) to compose a white paper on the recruitment and retention of female neurosurgical residents and practitioners. INTRODUCTION: Neurosurgery must attract the best and the brightest. Women now constitute a larger percentage of medical school classes than men, representing approximately 60% of each graduating medical school class. Neurosurgery is facing a potential crisis in the US workforce pipeline, with the number of neurosurgeons in the US (per capita) decreasing. WOMEN IN THE NEUROSURGERY WORKFORCE: The number of women entering neurosurgery training programs and the number of board-certified female neurosurgeons is not increasing. Personal anecdotes demonstrating gender inequity abound among female neurosurgeons at every level of training and career development. Gender inequity exists in neurosurgery training programs, in the neurosurgery workplace, and within organized neurosurgery. OBSTACLES: The consistently low numbers of women in neurosurgery training programs and in the workplace results in a dearth of female role models for the mentoring of residents and junior faculty/practitioners. This lack of guidance contributes to perpetuation of barriers to women considering careers in neurosurgery, and to the lack of professional advancement experienced by women already in the field. There is ample evidence that mentors and role models play a critical role in the training and retention of women faculty within academic medicine. The absence of a critical mass of female neurosurgeons in academic medicine may serve as a deterrent to female medical students deciding whether or not to pursue careers in neurosurgery. There is limited exposure to neurosurgery during medical school. Medical students have concerns regarding gender inequities (acceptance into residency, salaries, promotion, and achieving leadership positions). Gender inequity in academic medicine is not unique to neurosurgery; nonetheless, promotion to full professor, to neurosurgery department chair, or to a national leadership position is exceedingly rare within neurosurgery. Bright, competent, committed female neurosurgeons exist in the workforce, yet they are not being promoted in numbers comparable to their male counterparts. No female neurosurgeon has ever been president of the AANS, Congress of Neurological Surgeons, or Society of Neurological Surgeons (SNS), or chair of the American Board of Neurological Surgery (ABNS). No female neurosurgeon has even been on the ABNS or the Neurological Surgery Residency Review Committee and, until this year, no more than 2 women have simultaneously been members of the SNS. Gender inequity serves as a barrier to the advancement of women within both academic and community-based neurosurgery. STRATEGIC APPROACH TO ADDRESS ISSUES IDENTIFIED: To overcome the issues identified above, the authors recommend that the AANS join WINS in implementing a strategic plan, as follows: 1) Characterize the barriers. 2) Identify and eliminate discriminatory practices in the recruitment of medical students, in the training of residents, and in the hiring and advancement of neurosurgeons. 3) Promote women into leadership positions within organized neurosurgery. 4) Foster the development of female neurosurgeon role models by the training and promotion of competent, enthusiastic, female trainees and surgeons.     

History and current state of neurosurgery at the Medical University of South Carolina

We review the development of neurosurgery at the Medical University of South Carolina (MUSC) and the emergence of MUSC as a leading academic neurosurgical center in South Carolina. Historical records from the Waring Historical Library were studied, former and current faculty members were interviewed, and the personal records of Dr Phanor J Perot were examined. Dr Frederick E Kredel was the first to perform cerebral revascularization in stroke patients using omental flaps and the first to culture glioma cells in artificial media. The MUSC Neurosurgery residency program was established in 1964 by its first formally trained neurosurgeon, Julian Youmans, MD. The first graduate of the program, Dr Russell Travis, went on to become the President of the American Association of Neurological Surgeons. In 1968, the longest serving chairman, Dr Perot, joined the department and conducted significant research in spinal cord injury, receiving a continuous, 20-year award from the National Institute of Neurological Disorders and Stroke. A major change in the neurosurgery program occurred in 2004 when Dr Sunil Patel accepted the chairmanship. He integrated neurosurgery, neurology, and basic neuroscience departments into a comprehensive Department of Neurosciences to provide integrated clinical care. This department now ranks second in the country in National Institutes of Health research funding. Recently, the Center for Global Health and Global Neurosurgery was established with a vision of caring for patients beyond national borders. Neurosurgery at MUSC has been influenced by Drs Kredel and Perot and the current leadership is moving forward with a uniquely integrated department with novel areas such as global neurosurgery.     

A standardized method for assessment of elbow function. Research Committee, American Shoulder and Elbow Surgeons.

The American Shoulder and Elbow Surgeons have adopted a standardized form for assessment of the elbow. This form was developed by the Research Committee of the American Shoulder and Elbow Surgeons and subsequently adopted by the membership. The patient self-evaluation section contains visual analog scales for pain and a series of questions relating to function of the extremity. The responses to the questions are scored on a 4-point ordinal scale. The physician assessment section has 4 parts: motion, stability, strength, and physical findings. It is hoped that adoption of this method of data collection will stimulate multicenter studies and improve communication between professionals who assess and treat patients with elbow disorders.     

Art, passion, and neurosurgery: the role of the Society of Neurological Surgeons in academic neurosurgery

Neurosurgery is at a crossroads in a time of economic uncertainty. It is also a time of remarkable potential for innovation resulting in dramatic improvement in the way neurosurgeons care for patients and the quality of outcomes. Analysis of this key time point of neurosurgical history is drawn from reflections for a presidential address to the Society of Neurological Surgeons. It is the author's opinion that the best of academic neurosurgery must and will accept this challenge by developing not only the research but also the creativity and art of what neurosurgeons do for maximal patient benefit in research, educational, and clinical missions.     

Outcomes analysis of the treatment of carotid artery disease

The author presents a brief review of the methodologies of outcomes analysis. Recent large database outcomes studies on patients undergoing carotid endarterectomy are also reviewed and compared with the data generated from two prospective randomized studies, and large database outcomes analysis are discussed. The efforts of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons Outcomes Committee to perform online, multicenter outcomes studies are reviewed.     

History of outcomes measures in neurosurgery

This article provides a brief overview of the history of the origin of surgical outcomes studies in North America as exemplified by the career of E. A. Codman, MD. The influence of Harvey Cushing on Codman's interest in documenting the end results of surgical care is reported. The lessons gained from Codman's experience and difficulties are related to the efforts of the American Association of Neurological Surgeons/Congress of Neurological Surgeons Outcomes Committee to develop an international neurosurgical outcome reporting system.     

Fifty years of the congress of neurological surgeons: foundations, objectives, and legacies

As the Congress of Neurological Surgeons (CNS) approaches its 50th anniversary, we review the genesis of our professional society, the environment in which it was created, and the legacies it has established. The CNS was the first nonexclusive, international neurosurgical organization with no ostensible limitations to membership. From its unpretentious origins, the CNS has grown remarkably in size and scope, yet it has remained focused on its original primary objectives: education, the young neurosurgeon, membership, and volunteerism for the benefit of our specialty. During its 50-year history, the CNS has established a number of lasting legacies that have positively influenced the development and maturation of our chosen specialty. Neurosurgery is unique in having benefited from two strong national member organizations to ensure representation of different generations and perspectives for policy-making, to provide for two comprehensive annual meetings and complimentary journals, to broaden the representation for neurosurgery in our interaction with outside agencies, and to minimize the cost of services provided on behalf of neurosurgeons.     

Neurosurgery in India

Summary This is a brief account of Neurosurgery in India. Prior to 1949, Neurosurgery was being practised by General Surgeons. With the return of Professor Jacob Chandy to the Christian Medical College, Vellore in 1949 modern neurosurgery was born and progressed, and today there are more than 180 neurosurgeons in India. Even so, the ratio works out to one neurosurgeon for every 3,600,000 individuals! Conditions commonly encountered such as hydrocephalus, craniovertebral anomalies, pyogenic, fungal and tuberculous infections of the central nervous system, and fluorosis are being discussed. Stereotaxic surgery for pain, epilepsy, behaviour disorders and involuntary movements is being practised at several centres especially at Madras. Following the workshops conducted by Professor Pia and his coworker Professor Grote, enthusiasm for microneurosurgery has waxed.     

Neurosurgery in the decade of the brain. The 1990 AANS presidential address

The decade of the 1990's has provided neurosurgery with multiple challenges and opportunities. Numerous developments hold a promise for making the 1990's the most rewarding decade of the 20th century for neurosurgery. The "Decade of the Brain" resolution, adopted by the United States House and Senate and signed into law by President Bush in 1989, has provided the specialty with staggering opportunities. Neurosurgery and the basic and clinical neurosciences would be strengthened by the development of a major new philanthropic organization called the "American Brain Association" that would carry the activities of the Decade of the Brain into the 21st century. Major efforts are being made to improve organized neurosurgery's responsiveness to member needs. These include the strategic planning project undertaken by the Board of Directors of the American Association of Neurological Surgeons (AANS) and efforts to strengthen the Joint Council of State Neurosurgical Societies. The AANS has been extremely active in representing the specialty in legislative matters in Washington and in multiple other forums. This Association has joined The American Board of Neurological Surgery and the Residency Review Committee in responding to orthopedic surgery's proposal for spine fellowships. It is proposed that the logo of the state, regional, and national neurosurgical societies be changed to depict our involvement in spinal surgery (as well as brain surgery) because spinal surgery represents more than half of the total effort of this specialty. The standards of worth and value that provide the driving force behind our work emphasize the need to grow in compassion as manifested by our kindness, sincerity, and concern as we grow in professional competence as reflected by our training, knowledge, and skill.     

Lumbar stenosis: a personal record. Invited submission from the Joint Section Meeting on Disorders of the Spine and Peripheral Nerves, March 2004

Although its management continues to evolve, lumbar stenosis remains a common societal problem. The present article is based on an invited lecture at the 2004 Annual Meeting of the Congress of Neurological Surgeons/American Association of Neurological Surgeons Joint Section on Disorders of the Spine and Peripheral Nerves. In it the authors provide a historical overview of lumbar stenosis and describe how the senior author's treatment of this condition has evolved over the past four decades. Within each era of treatment, the reasons for modification of treatment methods and relevant outcome measures are outlined. Additionally, specific subsets of patients with lumbar stenosis are also discussed to emphasize unique characteristics that affect treatment strategies. The authors' present technique for management of lumbar stenosis is also illustrated.     

Origin and evolution of the Department of Neurosurgery, Neurological Institute, Faculty of Medicine, Kyushu University

The Department of Neurosurgery at Kyushu University had its origins within the First Department of Surgery and was established as a subspecialty at the Neurological Institute more than 30 years ago under the leadership of Katsutoshi Kitamura. Further development of the neurosurgical department has proceeded during the chairmanship of Masashi Fukui. These leaders and many other dedicated physicians and surgeons, nurses, investigators from other countries, and staff members have contributed to the creation of a research-oriented neurosurgical environment that interacts fruitfully with the other components of the Neurological Institute. This article describes the development of neurosurgery within Kyushu, which has been a highly cosmopolitan area throughout its long history. More specifically, this account outlines the origin and growth of the Department of Neurosurgery at Kyushu University.     

Crisis in resources: a neurosurgical prospective

In the light of the recent recommendations of the Society of British Neurological Surgeons on safe neurosurgery, we prospectively audited the work load, availability and efficiency in the use of neurosurgical resources in our department over a 1-month period. There were a total of 130 admissions--70 emergency and 60 elective cases. Twenty-three patients referred as emergencies were denied admission, directly or indirectly, because of shortage of beds. Other emergency cases had to wait unacceptable long periods, up to 17 days, prior to admission for the same reason. For elective cases, there was a 33% cancellation rate due to lack of beds and competition with the emergency cases for the same resources. Overall bed occupancy rate exceeded 100%. We conclude that the current neurosurgical resources are inadequate and over-stretched leaving no safety margin. Neurosurgery as a core emergency service, therefore, should be given priority in NHS resource allocation.     

An otolaryngology surgical coding and reporting system

A computerized information-gathering system has been developed at The University of Texas Health Science Center at Dallas for otolaryngologic head and neck surgery. Surgeons enter data on operations by answering multiple-choice questions at computer terminals situated near the operating rooms of each hospital. The system's main functions are to ensure completeness in the collection of operation data, allow easy review of such data for weekly conferences, and increase availability of such information for future comprehensive analysis. The scheme for data input, the logics of classifications, and the benefits of such a system are described.     

Dissecting a complex neurosurgical illustration: step-by-step development

Modern computer graphics software has enabled the medical illustrator to render very complex anatomy by composing many different layers of drawings simultaneously. This and the author's capacity to take an "editorial" approach to compress several chronological events into a single, comprehensive two-dimensional illustration are analyzed in a step-by-step process. Through a series of images, the article provides a visual synopsis of the development of an illustration for an extensive clinical case: total sacrectomy performed through an all-posterior approach. Originally given as a slide presentation at the American Association of Neurological Surgeons Theodore Kurze Lecture in April 2011, the article provides some detailed notes on the techniques the author used to develop a comprehensive neurosurgical illustration.     

The AANS: the national and international organization for neurological surgery.

The President of the American Association of Neurological Surgeons (AANS) validates the AANS as the national neurosurgical organization. He describes improved management of major committees of neurological surgery by the Joint Officers of the AANS and the Congress of Neurological Surgeons. A strong argument and proclamation are presented to expand the international role of the former Harvey Cushing Society.     

Report of the World Federation of Neurosurgical Societies (WFNS) international course and Cameroon Neurosurgery Society Congress (CNS) Yaoundé (Cameroon), 1st--4th October 2007

Neurosurgery remains a very marginal activity in sub-Saharan Africa. In this part of the world which counts nearly 40 countries, some do not have a single neurosurgeon, some have one to five, the number of ten neurosurgeons per country remaining an exception! In its concern of popularizing and of developing neurosurgery worldwide, the WFNS organized an international course in Africa, October 2007 2nd-3rd in Yaoundé (Cameroon). The Cameroon Neurosurgery Society (CNS) took this opportunity to organize its very first congress in the presence of the WFNS delegation from October 1st to 4th, 2007. The joint meeting with the WFNS was baptized the "African Week of Neurosurgery". This special event was a first in sub-Saharan Africa. The delegation of the WFNS, led by Professor J. Brotchi (Belgium) President of the WFNS, was made up of Professors A. Sousa (Brazil), Mr. Choux (France), N. Tribolet (Swiss), M. Arraez (Spain), A. Bricolo (Italy), A. Kamlichi (Morocco), G. Dechambenoit (France), K. Kalangu (Zimbabwe). Twenty three neurosurgeons coming from nine African countries (Cameroon, Nigeria, Gabon, Congo, Niger, Burkina Faso, Ivory Coast, Senegal, and Guinea) took an active part in work. The scientific success of this event led to the creation of the "Association of Neurological Surgeons of Africa (ANSA)" which will be the WFNS-Africa interface in order to insure the development of neurosurgery in Africa.     

The current state of neurosurgery in Japan

JAPAN HAS TWO large neurosurgical societies, the Japan Neurosurgical Society (JNS) and the Japanese Congress of Neurological Surgeons (Japanese CNS). The JNS was founded in 1948, and the Japanese CNS in 1981. The total number of neurosurgeons in Japan exceeds 7500, with 5432 board certified. There are 1340 training centers for neurosurgery in Japan; they are classified into two categories: Category A centers and Category C centers (training subcenters). For a neurosurgeon to be eligible to take the specialty board examination, he or she is required to have finished at least 6 years of training at a designated training center. A characteristic of Japanese neurosurgery is that neurosurgeons are engaged not only in surgical operations but also in various related activities, including performing radiological diagnostic procedures, such as angiography and endovascular surgery; working in the emergency room; and sometimes participating in neurorehabilitation and gamma knife treatment. In addition, a large number of neurosurgeons are engaged in research in various related fields. The JNS began to publish its official journal in 1948, initially in the Japanese language. Since 1990, the journal has been published exclusively in English (Neurologia Medico-chirurgica), whereas the official journal of the Japanese CNS is published in Japanese (Japanese Journal of Neurosurgery). Japan is blessed with advanced diagnostic and surgical technologies and instruments. They are available as needed throughout the country. Medical insurance is fully covered by the government or public insurance system; there is basically no private insurance in Japan. This article mentions socioeconomic problems relating to neurosurgical practice.
