Excelencia en Neurocirugía: María Cristina García-Sancho, the First Latina Neurosurgeon in the World.

BACKGROUND: Neurosurgery is a specialty that has been dominated by males. Although there has been an increase in the number of women in the field, it is not yet close to being equal. Some noteworthy women who have carved the path for other women to follow in their footsteps include Drs. Sofía Ionescu and Diana Beck, the first and second female neurosurgeons worldwide, respectively. However, there are limited publications on Dr. María Cristina García-Sancho, the first Latina neurosurgeon. METHODS: The purpose of this review was to illuminate the neurosurgical community on the life of Dr. García-Sancho. A thorough literature was performed on medical and non-medical publications that were either authored by Dr. García-Sancho or mentioned her directly. RESULTS: Dr. García-Sancho earned her medical degree at the School of Medicine of the National Autonomous University of Mexico under the guidance of Dr. Clemente Robles, who founded Mexico's first neurosurgical department. Her training took her worldwide. CONCLUSIONS: Her expertise allowed her to pioneer a revolutionary advancement known as the one-step bilateral cordotomy. Her perseverance led her to becoming the head of the Department of Neurosurgery at the National Cancer Institute of Mexico and co-found the Mexican Society of Neurological Surgery, where she served on the board of directors. This review aims to advocate for an equitable environment in the field of neurosurgery with Dr. García-Sancho's story.

A Beautiful Friendship-and a Lesson about Friends and Colleagues: A Classic Partnership Revisited.

David Warner, M.D., and Michael Todd, M.D., first met in 1985. They began working together at the University of Iowa (Iowa City, Iowa) a year later with a shared interest in both laboratory and clinical neuroscience-and in the operative care of neurosurgical patients. That collaboration has now lasted for 35 yr, resulting in more than 70 joint publications. More importantly, they have had the privilege of working together with close to 1,000 colleagues from around the world, in a dozen medical specialties. Their careers are an example of what can be accomplished by friendship, mutual commitment, persistence, and a willingness to join with others.

Nancy Davis Reagan, First Lady with a Neurosurgical Legacy.

Various well-known people associated with the history of the presidency of the United States have experienced neurologic disease or injury, especially trauma to the head or spine. Nancy Reagan, however, as the wife of President Ronald Reagan and First Lady, would leave a significant and lasting mark on the progress of neurosurgical science and education. Recognized for endeavors against drug abuse, Alzheimer disease, and polio, her interest in neurosurgical research is less well known. Nancy's father Loyal Davis was a remarkable neurosurgeon and educator of extraordinary influence. When Barrow Neurological Institute (BNI) founder John Green experienced complications after an illness, Davis served as BNI director during 1966 - 1967. After Davis's death in 1982, Robert Spetzler, who had been a student of Davis at Northwestern University Medical School and was then BNI director, convinced Green, despite his misgivings, to support a neurosurgical laboratory recognizing Davis. In 1988, Nancy Reagan, then First Lady, dedicated the Loyal and Edith Davis Neurosurgical Research Laboratory. At the dedication, she remarked on her years growing up in the home of a pioneering neurosurgeon and remarked that "my father believed deeply in the importance of research to develop new methods for treating patients." Green and Spetzler's unified efforts honored the extraordinary career of Davis in a manner he would have appreciated, were supported by a First Lady with deep involvement in politics and philanthropy dedicated to promoting advances in medicine, and are part of neurosurgery's unique heritage.

Progress in neurosurgery: Contributions of women neurosurgeons in the Middle East.

The Middle East is known for its complex history and rich environment and culture. The region is home to a wide variety of traditions, cultures and religions, which have made the area vulnerable to political conflicts. Despite these difficulties, science and medicine have always thrived in the region, with many medical practices and principles established by physicians and scholars living in the Middle East. The first academic neurosurgical activity in the region started in the 1950s. The first women neurosurgeons in the Middle East started training in the 1970s, and were from Iran, Palestine, followed by Saudi Arabia in the 1970s. These pioneers have encountered serious challenges, yet have become role models for the next generation. These women have paved the way and facilitated neurosurgical training and practice for more women surgeons. The gradual increase in the number of women neurosurgical residents in the region leads to the expectation that women will play a more prominent role in the future as leaders in neurosurgery in the Middle East. This collaborative study, which identifies the known women neurosurgeons in the Middle East for the first time, may serve to provide background and context for further contributions of women neurosurgeons for our profession and our patients.

Progress in neurosurgery: Contributions of women neurosurgeons in Latin America.

Nearly 75 years after the first woman neurosurgeon was trained in Latin America, the field of neurosurgery is changing and the prominence of women neurosurgeons within the specialty is increasing. By researching the histories of individual physicians and neurosurgeons, as well as neurosurgical departments and societies, we present, for the first time, the history of the women in neurosurgery in Latin America. Women neurosurgeons in the region have made notable progress, inspiring subsequent generations and actively participating in organized neurosurgery, medical leadership outside neurosurgery, academic neurosurgery, and leadership in contemporary society. The establishment of "Women in Neurosurgery" networks and organizations has been important to the success of many of these efforts. This collaborative study, which identifies the known women neurosurgeons in Latin America for the first time, may serve to provide background and context for further contributions of women neurosurgeons for our profession and our patients.

Progress in neurosurgery: Contributions of women neurosurgeons in Asia and Australasia.

At the end of the first 100 years of neurosurgery as a specialty, it is appropriate to look back and then imagine the future. As neurosurgery celebrates its first century, the increasing role of women neurosurgeons is a major theme. This article documents the early women pioneers in neurosurgery in Asia and Australasia. The contributions of these trailblazers to the origins, academics, and professional organizations of neurosurgery are highlighted. The first woman neurosurgeon of the region, Dr. T.S. Kanaka of India, completed her training in 1968, not long after the trailblazers in Europe and North America. She heralded the vibrant communities of neurosurgical women that have developed in the vast and diverse nations of the region, and the many formal and informal groups of women in neurosurgery that have introduced and promoted talented women in the profession. Contributions of women neurosurgeons to academic medicine and society as a whole are briefly highlighted, as are their challenges in this male-dominated specialty. The region is home to many deeply conservative societies; in fact, some nations in the region have not yet trained their first woman neurosurgeon. The fortitude of these individuals to achieve at the highest levels of neurosurgery indicates great potential for future growth of women in the profession, but also demonstrates the need for initiatives and advocacy to reach the full potential of gender equity.

European women in neurosurgery: I - A chronology of trailblazers.

Neurosurgery as a distinct speciality has been around for 100 years. Some of the earliest women neurosurgeons were European, emerging from the 1920's onwards. Here we detail the rise of women in neurosurgery across Europe with a decade by decade account of big events and firsts across the continent. The emerging themes are seen in stories of pioneers with enormous resilience, camaraderie, trailblazing and triumphing in a system with great obstacles and challenges. Our journey through this chronology brings us to the modern day, where most European countries have or have had a woman neurosurgeon and the future for women in neurosurgery in the continent is very bright.

Four Athenas - Europe's first female neurosurgeons.

In the early 20th century, a tumultuous era was yielding geopolitical and social change. Europe at large was undergoing redefinition of borders, political structures, and economies, while rebuilding societies after World War I. At the same time, neurosurgery was emerging as a new specialty, and women were allowed to study medicine for the first time in many European countries. These factors created a synergy, setting the stage for Europe's four first female neurosurgeons to emerge. In 1924, Germany's Alice Rosenstein began her neurosurgical career and contributed to the refinement of pneumoencephalography. Due to her Jewish background, she was forced to flee Europe, emigrating to the United States, where she did not continue to practice neurosurgery. In 1929, Russia's Serafima Bryusova began her neurosurgical training. She studied intracranial pressure in trephined patients and wrote the first Russian monograph on cerebral angiography before she was immobilized by severe arthritis. England's Diana Beck began her neurosurgical career in 1939. She contributed to the surgical treatment of intracerebral hemorrhage and researched idiopathic intracranial hypertension, even though many believed she could not be a successful surgeon due to her myasthenia gravis. In 1943, Romania's Sofia Ionescu started a prolific academic neurosurgical career. She developed a minimally-invasive technique to treat intracerebral hematomas and worked tirelessly to bring neurosurgery to all corners of her country. Europe's first women in neurosurgery were marked by war and adversity. Their stories carry within them a spirit of resilience, fortitude, and tenacity that continues to characterize women in neurosurgery today.

European women in neurosurgery: II - Historical characters and living legends.

A collaborative global working group of women neurosurgeons in multiple countries at different stages of their neurosurgical careers undertook the task of researching the history of European women in neurosurgery. While doing so, we happened upon many remarkable female neurosurgeons who overcame great adversity, made tremendous contributions to society and institutional neurosurgery, and displayed numerous talents beyond the operating room. In the first part of this paper, we recounted a chronology of female neurosurgeons in Europe, highlighting the most remarkable achievements of women in every decade, from the 1920's to 2020. In this paper, we honor fascinating women in European neurosurgery, both historical characters and living legends. These women have overcome great adversity and have also excelled in a huge variety of pursuits. While some were themselves refugees, we also have uncovered noteworthy examples of women who immersed themselves in humanitarian missions and who tried to better the world through political action. There are stories of women beating the odds, taking on biased institutions and proving their worth, in spite of the prevailing system. Most inspirational, we have discovered through our comprehensive research on the history of women in European neurosurgery that the future is increasingly female.

Women in Neurosurgery: From a Matter of Fortuitous Occasions Toward a Conscious Choice.

BACKGROUND: Medicine has made progress toward gender equality and has achieved almost equal distribution between men and women among graduates. However, more still needs to be done because most surgical subspecialties are still lacking adequate female representation and this persisting gender gap is particularly evident in both practical neurosurgery and the academic world. Gradual advancements have enabled a few women to pursue a successful career in neurologic surgery, pairing clinical practice with mentoring and involvement in academic research. These efforts show that more needs to be done to bridge the historic and current gap, which has recently aroused increasing interest among the neurosurgical community through internationally relevant studies. In neurosurgical societies worldwide, the existence of gender-related issues and women-reserved sections has started to attract attention and recognition on how to properly address this issue among present and future neurosurgeons. METHODS: In this study, we discuss the timeline of women's road to gaining their place in neurosurgery, inspired by Hippocrates' motto "Declare the past, diagnose the present, foretell the future." Although neurosurgery had been traditionally considered too difficult a subject in which to engage, the first female neurosurgeons challenged themselves in this field, previously reserved only for men, at a time when society was not yet ready to embrace women's presence. Their successes paved the way for future generations of women, progressively shedding light on complex themes such as peer considerations, difficulty in reaching academic positions, and work-life balance. RESULTS: Our aim is to analyze the historic reasons for inequality among men and women, which might be found in the themes of personal choice and willingness, aside from cultural bias or stereotypically based thinking. CONCLUSIONS: Accordingly, if the difference in numbers were considered a reality related to personal inclination, perhaps, nobody would pay attention to this topic and the presence of even a few women in neurosurgery would be considered less strange. By thinking along those lines on a daily basis, we could all simply write about the history of valuable neurosurgeons in the past, present, and future without any distinction between men and women.

Dominique Anel, John Hunter, and the Eponymous Hunterian Ligation of Aneurysms: Conception to Current Practice.

The contributions of both Dominique Anel and John Hunter in the development of the eponymous Hunterian ligation of aneurysms are presented. John Hunter, the "father of scientific surgery" lent his name to the eponymous practice of applying ligatures to aneurysmal dilatation of arteries. However, evidence suggests that the operation might antedate him by decades. Dominique Anel was a surgeon in the time of Louis XIV who, after his initial apprenticeships in Toulouse and Montpellier, subsequently served in the French navy. He famously described the lacrimal syringe that bears his name but was also interested in diseases of the bones and arteries. Anel described his technique of ligating an aneurysm of the brachial artery in the winter of 1709-1710 in Turin. His description of ligating just the upper end of the aneurysm without touching the sac was described in his collected works in 1714. This technique was exactly the same as that used by Hunter. However, Hunter had based his decision not to excise the sac on his own research. Hunterian ligation was used routinely before endoaneurysmorrhaphy, after which its popularity declined. Hunterian ligation has been superseded by development of surgical clips and endovascular techniques for intracranial aneurysms. However, the technique is still described occasionally in vascular and neurosurgical literature in the context of treating large aneurysms not amenable to traditional treatment modalities.

Tribute to Theodor Kocher: Far Beyond an Anatomical Reference

We know Kocher's name as an anatomical reference in neurosurgery. In fact, Theodor Kocher was a Swiss general surgeon, and his contributions were such that Kocher was honored in 1909 with the Nobel Prize in Medicine and Physiology, and he was the first surgeon to receive this honor. Kocher participated in the initial scientific phase of medicine, livingwith names that are in history, as well as him; Langenbeck and Virchow, Lucke, Billroth, Horsley, Lister, Halstedt, Pasteur, Osler, Lawson Tait, Verneuil, and a long list and other icons of the time. The present account rescues the many important facets and contributions of the Swiss surgeonTheodor Kocher, and his relationship with several of them. Kocher's memory, surgical instruments and literary production are preserved in a small wing of the University of Bern. The present article highlights how intense Kocher's dedication to the medical field was.

Staged Cranial Surgery for Intracranial Lesions: Historical Perspective.

We follow the development of staged resection from its first description by Walter E. Dandy, one of the founding fathers of neurosurgery, in 1925 in which he removed a large vestibular schwannoma.This historical vignette cites neurosurgical case reports and literature to demonstrate the evolution of staged resection of intracranial lesions, from Dandy's initial use to its becoming a more viable and safe option for the treatment of meningiomas, vestibular schwannomas, and skull base lesions (among numerous other intracranial pathologies). We also discuss the current advancements and future perspectives of staged resection that may show promise in effectively treating a wide range of pathologies while simultaneously reducing morbidity rates-a warrant for further exploration of staged cranial surgery as an important tool in neurosurgery.

Harvey Cushing's Wanderjahr (1900-1901).

Harvey Cushing's 14-month Wanderjahr had a profound effect on his subsequent personal career, which in turn ushered in the modern age of American neurosurgery. From July 1900 to August 1901, he traveled to European neurosurgical centers in England, France, Switzerland, Italy, and Germany. His excursion happened at a crucial moment in his trajectory; it was built on his existing foundation of Halstedian surgical training and occurred at a time when interest in the special field of neurological surgery was emerging. The research and clinical experiences on his journey-good and bad-undoubtedly informed his fledgling neurosurgical practice. We present a concise account of Harvey Cushing's time in Europe that consolidates accounts from Cushing's travel journals, biographers, and other neurosurgeons. This article highlights tensions in prior works and reveals new insights into the transformative nature of his Wanderjahr. Furthermore, we contextualize his travels and achievements within the broader transformation of American medical education at the turn of the 20th century to elucidate how Europe influenced American medicine. We briefly consider parallel benefits of Harvey Cushing's Wanderjahr and modern domestic or international training opportunities and present potential areas of implementation.

The History of Neurosurgery at Houston Methodist Hospital.

The history of neurosurgery in Texas is linked with the development over the past century of the Houston Methodist Hospital (HMH) from a 30-bed hospital in downtown Houston to an academic medical center with 900 beds in the Texas Medical Center. Neurosurgery at HMH has developed to meet the needs of the Houston Metropolitan Area, which has grown from 130,000 people in 1919 to 7 million people today. Neurosurgery at HMH has had steady growth and stable leadership with Dr. James Greenwood Jr. 1936-1980, Dr. Robert Grossman 1980-2013, and Dr. Gavin Britz 2013-present, as Chiefs of the Neurosurgical Service. HMH has been affiliated with 2 medical schools: Baylor College of Medicine 1950-2003 and Weill College of Medicine Cornell University 2004-present. Neurosurgical training began at HMH with the establishment of the Baylor College of Medicine Neurosurgery Residency Program with Dr. George Ehni as Program Director 1959-1979 and Dr. Robert Grossman as Program Director 1980-2006. Training has continued in the HMH residency program from 2006 to present with Dr. David Baskin as Program Director. As of 2019, 138 neurosurgical residents have been trained at HMH. The goals of delivering responsible patient care, advancing neurosurgical knowledge, and training the next generation of practitioners and teachers of neurosurgery have remained constant and have been met and remain the mission of the department.

Reflexiones de un neurocirujano militar de la segunda mitad del siglo XX / Reflections of a military neurosurgeon from the second half of the 20th century

From the Historical Examples of Drs. Osler, Cushing, and Van Wagenen: Lessons on the Importance of Mentorship in Contemporary Neurosurgery.

Although the historical relationships between William Osler, Harvey Williams Cushing, and William Perine Van Wagenen are well known in the neurosurgical world, the nature of the mentor-mentee relationships that existed between these historical giants is not widely appreciated. In this historical vignette, we describe and exemplify such relationships, while at the same time extract important and applicable principles from them. We reviewed relevant primary and secondary sources that documented the interactions between Cushing, Osler, and Van Wagenen. In founding the field of neurological surgery, the brilliant yet volatile Dr. Harvey Cushing received guidance from his mentor, Dr. William Osler. Through our review, it is undeniable that Dr. Osler's personal and professional guidance was vital to young Dr. Cushing's success as the founder of modern neurosurgery. Likewise, Cushing's tutelage of Van Wagenen enabled Van Wagenen to become a leader of a second generation of neurosurgeons, thereby perpetuating the existence of Cushing's high neurosurgical standards. These historical mentor-mentee relationships were built on 4 primary components: accurate recognition of talent, guidance, arrangement of opportunity, and sustenance of mentorship-actions that are commonly implicated in effective mentorship in contemporary studies. Proper mentorship remains indispensable for the success of neurosurgical trainees.

Cerebral Impaludation - An Ignoble Procedure between Two Nobel Prizes: Frontal Lobe Lesions before the Introduction of Leucotomy.

During the 20th century, only two persons have been awarded the Nobel Prize for psychiatric discoveries, Julius Wagner-Jauregg in 1927 for the introduction of malaria inoculation in dementia paralytica and Egas Moniz in 1949 for prefrontal leucotomy. According to traditional narrative, Moniz was inspired by a presentation by Carlyle Jacobsen on prefrontal lesions in chimpanzees at a congress in London in 1935. A few months later, he performed the first operations with the help of a young neurosurgeon. These leucotomies were done using injections of a small amount of alcohol into each frontal lobe through a single burr hole on each side of the skull, and the findings from the first 20 patients were published soon after that in 1936. It has, however, been difficult to reconstruct the path leading Moniz to frontal leucotomy, due to his unwillingness to acknowledge contributions from others. Maurice Ducosté, psychiatrist at Villejuif in Paris, France, started his work with psychiatric patients in the early 1920s with mechanical lesions in schizophrenia and continued with injections into the frontal lobes. Later, he focused on general paresis of the insane in neurosyphilis. Here, he introduced injections of malaria-infested blood into the frontal lobes - cerebral impaludation. Injections were used also in schizophrenia, mania, melancholia, and other psychiatric conditions. These injections were up to 5 mL in volume and could be repeated up to 12 times in an individual patient, which must have created significant lesions. Ducosté performed his procedure in hundreds of psychiatric patients before Moniz attempted leucotomy, and his work was presented in several publications before that by Moniz. Moniz basically used the same entry point, target depth, and technique in his first leucotomies. The major difference was that Moniz used alcohol with the clear intent of producing a lesion. Further, Moniz must have been aware of the work of Ducosté, since they presented papers, one after the other, at a meeting of the French Academy of Medicine in 1932. Even so, Moniz never acknowledged any contribution by Ducosté. In my opinion, it would be appropriate to acknowledge the contribution of Maurice Ducosté to the introduction of lobotomy.

Reflections on the History of Nerve Repair - Sir Sydney Sunderland's Final Presentation to the Neurosurgical Society of Australasia.

Sir Sydney Sunderland (1910-1993) was an eminent physician and anatomist who identified the fascicular structure of nerves, and developed the eponymous 5-tiered classification of nerve injuries. Not long before his death, he presented a keynote address to the Annual Scientific Meeting of the Neurosurgical Society of Australasia. Recently, the videotape of his presentation was discovered. In the presentation, Sir Sydney included discussion on the history of nerve repair, commencing with Herophilus and Galen, and progressing through the Middle Ages, including Leonardo of Bertapaglia, and he further noted the discoveries during the 1800s of the microscope, the axon, and nerve histology (including Remak, Schwann, Nissl, and Golgi), Waller's findings on nerve degeneration, and nerve injury (His, Cajal, Forsmann, and Harrison). Sir Sydney discussed nerve injuries sustained during World War I, with the deleterious effects of infection, and following the many nerve injuries sustained during World War II, he discussed his own discoveries of internal topography of nerve fascicles, and the anatomical substrate of nerve fascicles that limit surgery for nerve repair, nerve grafts, and the basic science of spinal cord repair. This paper presents a transcript of Sunderland's presentation and includes many of his original images used to illustrate this tour de force of nerve repair.
