Thyroidectomy Then and Now: A 50-Year Australian Perspective.

BACKGROUND: Since the mid-1800s, thyroidectomy has transformed from a procedure associated with high to near-zero mortality. Nonetheless, surgeons must continue to strive to improve patient care. Using historical records and contemporary data, this study compares the practice and outcomes of thyroid surgery at a tertiary institution during two periods, 50 years apart. METHODS: 'The Alfred Hospital Clinical Reports' recorded all cases of surgically managed thyroid disease from 1946 to 1959. These historical cases were compared to contemporary thyroidectomy cases at the Alfred Hospital from 2007 to 2016. Cases were compared for surgical indication and post-operative outcomes. RESULTS: There were 746 patients in the historical group (mean age 53 years; 87% female) and 787 patients in the contemporary group (mean age 52 years; 80% female). The most common indication for thyroidectomy in both groups was non-toxic nodular goitre. A greater proportion of the contemporary group were diagnosed with thyroid malignancy (27% vs. 8%; p < 0.001). The contemporary group recorded significantly fewer cases of thyrotoxic crisis (2.1% vs. 0%; p = 0.001), permanent nerve palsy (4.6% vs. 0.4%; p < 0.001) and bilateral nerve palsy (1.2% vs. 0%; p = 0.01). There were no mortalities in the contemporary group, while the historical data recorded three deaths (0.44%). CONCLUSIONS: This study compared thyroid surgery in two cohorts separated by a 50-year period. While it is not surprising that outcomes of thyroidectomy have improved, this study uniquely demonstrates trends of thyroid surgery over time and areas in which further improvements may be made.

An Interview with Dr. John L. Cameron, the Hall of Famer of Pancreatic Cancer.

The Society of Surgical Alimentary Tract (SSAT) Resident Education Committee aim is to facilitate resident participation in the annual meeting and foster the education of the next generation of gastrointestinal. The SSAT "Residents Corner" was developed as a video-blog highlighting areas of interest for surgical trainees looking to focus on a career in gastrointestinal surgery. The topics covered are to make surgical education more accessible, one way is to highlight leaders in the field who discuss their journey. A 10-min video of a surgical mentor is recorded and archived on the SSAT site under a video series called "Mentor of the Month." A synopsis of a video published online February 2018 featuring Dr. John Cameron interviewed by one of his trainee, Dr. Vanita Ahuja. Dr. Cameron shares his thoughts on his accomplishments, challenges, and advice for young surgeons and the future of pancreatic surgery. The interview offers an insight into the mind of one of the greatest leaders of surgery of our time.

Dr. Robert G. Heath: a controversial figure in the history of deep brain stimulation.

The history of psychosurgery is filled with tales of researchers pushing the boundaries of science and ethics. These stories often create a dark historical framework for some of the most important medical and surgical advancements. Dr. Robert G. Heath, a board-certified neurologist, psychiatrist, and psychoanalyst, holds a debated position within this framework and is most notably remembered for his research on schizophrenia. Dr. Heath was one of the first physicians to implant electrodes in deep cortical structures as a psychosurgical intervention. He used electrical stimulation in an attempt to cure patients with schizophrenia and as a method of conversion therapy in a homosexual man. This research was highly controversial, even prior to the implementation of current ethics standards for clinical research and often goes unmentioned within the historical narrative of deep brain stimulation (DBS). While distinction between the modern practice of DBS and its controversial origins is necessary, it is important to examine Dr. Heath's work as it allows for reflection on current neurosurgical practices and questioning the ethical implication of these advancements.

The History of Enhanced Recovery After Surgery and the ERAS Society.

This short historical overview explains the development of enhanced recovery from a small group of surgeons in European academic centers to the establishment of ERAS®Society, a not-for-profit multiprofessional multidisciplinary medical-academic society, reaching all major continents and involving a wide range of surgical and anesthesia disciplines.

The adenoid: Its history and a cautionary tale.

The existence of the adenoid first appears to have been noted by Conrad Victor Schneider in 1661. James Yearsley reported in 1842 one case in which he improved hearing by removal of a mucus membrane from behind the uvula, which indicates some appreciation of a relationship of the nasopharynx to ear disease. Hans Wilhelm Meyer, in 1868, was the first to demonstrate the relationship of the adenoid to ear disease and to develop an effective, although somewhat difficult, surgical operation to remove the adenoid. Removal of the adenoid became rapidly accepted worldwide as a treatment for many morbidities, including otitis, speech problems, cognitive problems, and sleep apnea. Until the 1920s, adenoidectomy often was performed as a staged procedure and without general anesthesia. Early tools and techniques included use of the bare fingernail, a finger ring knife, a curette, and electrical desiccation. From the mid-1930s to the early 1960s, radiation therapy of the adenoid was in extensive use, both for children and in caring for army aviators and navy submarine crews during WWII. The effectiveness of surgical adenoidectomy for hearing loss led to a belief that radiation, which had been found to ablate lymphoid tissue, would be equally effective, and led to the wide-spread use of radiation. Ultimately, 500 thousand to 2.5 million children and adults were estimated to have been treated with radiation, and follow-up studies found increased risk for cancer. Furthermore, a follow-up study by Stacey R. Guild (1890-1966), published in 1950, on a very large sample of children who previously were reported to have had their hearing loss diminished through radiation, found that irradiation had produced no effect on high-tone loss. Thus, irradiation was both useless and harmful. Acceptance of authority, which can lurk within medical culture, led to the development of a tragically misguided management of adenoid disease.

The Unforgettable Neurosurgical Operations of Musicians in the Last Century.

BACKGROUND: There has been no study of craniotomies of famous musicians throughout history. This subject was investigated. METHODS: The key search words were "neurosurgery and music" and the names of composers. We used digital catalogs such as PubMed as well as university libraries. RESULTS: We found 4 musicians from the twentieth century with different neurosurgical diseases: Maurice Ravel, George Gershwin, Clara Haskil, and Pat Martino. CONCLUSIONS: Neurosurgical operations affected the musical careers and lives of mentioned musicians and two of them died. Neurosurgeons can understand the effect of limited diagnostic tools such as magnetic resonance imaging and computed tomography at the time on the poor outcome of 2 musicians.

Harvey Cushing and pituitary Case Number 3 (Mary D.): the origin of this most baffling problem in neurosurgery.

From the very beginning of his career, Harvey Williams Cushing (1869-1939) harbored a deep interest in a complex group of neoplasms that usually developed at the infundibulum. These were initially known as "interpeduncular" or "suprasellar" cysts. Cushing introduced the term "craniopharyngioma" for these lesions, which he believed represented one of the most baffling problems faced by neurosurgeons. The patient who most influenced Cushing's thinking was a 16-year-old seamstress named "Mary D.," whom he attended in December 1901, exactly the same month that Alfred Fröhlich published his seminal article describing an adiposogenital syndrome in a young boy with a pituitary cyst. Both Cushing's and Fröhlich's patients showed similar symptoms caused by the same type of tumor. Notably, Cushing and Fröhlich had met one another and became good friends in Liverpool the summer before these events took place. Their fortunate relationship led Cushing to realize that Fröhlich's syndrome represented a state of hypopituitarism and provided a useful method of diagnosing interpeduncular cysts. It is noteworthy that Cushing's very first neurosurgical procedure on a pituitary tumor was performed in the case of Mary D.'s "interpeduncular cyst," on February 21, 1902. Cushing failed to remove this lesion, which was later found during the patient's autopsy. This case was documented as Pituitary Case Number 3 in Cushing's masterpiece, The Pituitary Body and Its Disorders, published in 1912. This tumor was considered "a teratoma"; however, multiple sources of evidence suggest that this lesion actually corresponded to an adamantinomatous craniopharyngioma. Unfortunately, the pathological specimens of this lesion were misplaced, and this prompted Cushing's decision to retain all specimens and documents of the cases he would operate on throughout his career. Accordingly, Mary D.'s case crystallized the genesis of the Cushing Brain Tumor Registry, one of Cushing's major legacies to neurosurgery. In this paper the authors analyze the case of Mary D. and the great influence it had on Cushing's conceptions of the pituitary gland and its afflictions, and on the history of pituitary surgery.

Infectious Disease Risk Associated with Contaminated Propofol Anesthesia, 1989-2014(1).

Administration of propofol, the most frequently used intravenous anesthetic worldwide, has been associated with several iatrogenic infections despite its relative safety. Little is known regarding the global epidemiology of propofol-related outbreaks and the effectiveness of existing preventive strategies. In this overview of the evidence of propofol as a source of infection and appraisal of preventive strategies, we identified 58 studies through a literature search in PubMed, Embase, and Lilacs for propofol-related infections during 1989-2014. Twenty propofol-related outbreaks have been reported, affecting 144 patients and resulting in 10 deaths. Related factors included reuse of syringes for multiple patients and prolonged exposure to the environment when vials were left open. The addition of antimicrobial drugs to the emulsion has been instituted in some countries, but outbreaks have still occurred. There remains a lack of comprehensive information on the effectiveness of measures to prevent future outbreaks.

[Historical Review of Cesarean Section at King's Maternity Hospital and Midwifery School Zagreb 1908-1918].

This article presents a historical review of the performance of 23 cesarean sections at the King's Maternity Hospital and Midwifery School in Zagreb during the 1908-1918 period. Following prenatal screening by midwives and doctors in the hospital, deliveries in high risk pregnant women were performed at maternity hospitals, not at home. The most common indication for cesarean section was narrowed pelvis in 65.2% of women, while postpartum febrile condition was the most common complication in the puerperium. Maternal mortality due to sepsis after the procedure was 8.69% and overall perinatal mortality was 36.3% (stillbirths and early neonatal deaths).

[Caesarean section: History, epidemiology, and ethics to diminish its incidence]. / Operación cesárea. Una visión histórica, epidemiológica y ética para disminuir su incidencia.

Cesarean section has become the most performed surgery and it has been enhanced with the use of antibiotics and improvement in surgical techniques. The aim of this systematic review is to describe and clarify some historical and ethical characteristics of this surgery, pointing out some aspects about its epidemiological behavior, becoming a topic that should be treated globally, giving priority to the prevention and identification of factors that may increase the incidence rates. Today, this "epidemic" reported rates higher than fifty percent, so it is considered a worldwide public health problem. Consequently, in Mexico strategies aimed at its reduction have been implemented. However, sociocultural, economic, medicolegal and biomedical factors are aspects that may difficult this goal. As we decrease the percentage of cesarean section in nulliparous patients, we diminish the number of iterative cesarean and its associated complications. This aim must be achieved through the adherence to the guidelines which promote interest in monitoring and delivery care in health institutions of our country.

La operación cesárea es la cirugía mayor más frecuentemente practicada, y ha sido perfeccionada con el uso de antibióticos y mejores técnicas quirúrgicas. El objetivo de esta revisión sistemática es describir y precisar diversas características históricas y éticas con relación a esta intervención quirúrgica, señalando algunos aspectos inherentes a su comportamiento epidemiológico, siendo este último una problemática de actualidad y de suma importancia que debe tratarse de forma integral, dando prioridad a la prevención e identificación de los factores que hacen posible el aumento en las tasas de incidencia. Hoy en día, esta "epidemia" reporta tasas que superan el cincuenta por ciento, por lo que se ha considerado un problema de salud pública a nivel mundial. Consecuentemente, en México se han implementado estrategias tendentes a su disminución, no obstante, los factores socioculturales, económicos, médico-legales y biomédicos son aspectos que dificultan dicho objetivo. En la proporción en que se disminuya el porcentaje de cesárea en pacientes primigestas, disminuirá secundariamente el número de cesáreas iterativas y sus complicaciones asociadas, meta que debe alcanzarse mediante el apego a las guías que promueven el interés por la vigilancia y atención del parto en las instituciones de salud de nuestro país.

H.M. never again! An analysis of H.M.'s epilepsy and treatment.

On August 25, 1953, the patient H.M., aged 27, underwent a bilateral surgical destruction of the inner aspect of his temporal lobes performed by William Beecher Scoville with the aim to control H.M.'s drug refractory epileptic seizures and alleviate their impact on his quality of life. Postoperatively, H.M. presented for 55 years a "striking and totally unexpected grave loss of recent memories". This paper reports what we know about H.M.'s epilepsy before and after surgery and puts forward arguments supporting the syndromic classification of his epilepsy. We attempted to elucidate what could have been the rationale, in 1953, of Scoville's decision to carry out a bilateral ablation of H.M.'s medial temporal lobe structures, and we examined whether there was any convincing argument published before 1953 suggesting that bilateral hippocampal ablation could result in a permanent and severe amnesia. Our a posteriori analysis of H.M.'s medical history suggested that he was most probably suffering from idiopathic generalized epilepsy with absences and generalized convulsive seizures worsened by high dosage phenytoin treatment, or less probably from cryptogenic frontal lobe epilepsy. Importantly, he did not have temporal lobe epilepsy. Scoville based his proposal of bilateral mesial temporal lobe ablation on his experience as a psychosurgeon and on the assumption that the threshold of generalized epileptic activity could be lowered by some kind of hippocampal dysfunction potentially epileptic in nature. Given the scanty information on the link between amnesia and medial temporal lobe lesions that was available in humans in 1953, one can understand why Scoville was so surprised by the "striking and totally unexpected" memory loss he observed in H.M. after the bilateral ablation of his mesial temporal lobe structures.

The truth and coherence behind the concept of overdrainage of cerebrospinal fluid in hydrocephalic patients.

INTRODUCTION: Overdrainage, siphoning, and slit-ventricle syndrome are well-documented complications of shunting in hydrocephalic patients. Despite the prevalence of these conditions, their mechanisms are still not fully understood. In this paper, the authors trace the concept of overdrainage and the related phenomena of siphoning and slit-ventricle syndrome. PURPOSE: To provide a historical overview of overdrainage and to reignite discussion of a topic that has been settled. METHODS AND RESULTS: A medical literature search and review were performed via Google Scholar. Of 565 publications, 3 primary papers were identified and a timeline was developed demonstrating the convergence of the aforementioned concepts. From the primary papers, 25 relevant publications were selected and further analyzed searching for hypothesis, evidence, and conclusions. CONCLUSION: Overdrainage, siphoning, and slit-ventricle syndrome are associated concepts that have converged into a pathophysiological theory where siphoning of CSF leads to overdrainage, which is then hypothesized to cause slit-ventricle syndrome in a small subset of patients. Our data suggests that while there have been numerous reports regarding overdrainage and its consequences, the evidence is not as robust as currently presumed and this subject requires prospective exploration.
