Early neurosurgical procedures dealt mainly with treatment of head trauma, especially skull fractures. Since the early medical writings by Hippocrates, a great deal of respect was given to the dura mater, and many other surgeons warned against violating the dura. It was not until the 19th century that neurosurgeons started venturing beneath the dura, deep into the brain parenchyma. With this advancement, brain retraction became an essential component of intracranial surgery. Over the years brain retractors have been created pragmatically to provide better visualization, increased articulations and degrees of freedom, greater stability, less brain retraction injury, and less user effort. Brain retractors have evolved from simple handheld retractors to intricate brain-retraction systems with hand-rest stabilizers. This paper will focus on the history of brain retractors, the different types of retractors, and the progression from one form to another.

Nervous system involvement in Lyme disease was originally described as meningitis, cranial neuritis, and radiculoneuritis,1-3 but Lyme disease can also involve the brain parenchyma. We describe a child whose first manifestation of Lyme disease was an acute, focal meningoencephalitis with signs and symptoms such as fever, headache, slurred speech, hemiparesis, seizure, and CSF pleocytosis. CASE REPORT A 7-year-old boy was hospitalized Aug 27, 1985, because of hemiparesis. Six weeks prior to admission he had vacationed at Old Lyme, CT. There was no history of rash or tick bite. He had been well until eight hours prior to admission when fever and headache developed.

The history of neurosurgery falls naturally into the premodern era, where it is essentially the history of surgery to the skull and of head injuries, and the modern era, where it is the history of surgery to the brain itself, made possible by cerebral localization theory, antisepsis, and anaesthesia, all of which developed in the nineteenth century. The first known neurosurgical procedures were skull trephines, seemingly carried out on both the living and the dead. It is unclear whether these were performed for therapeutic or ritualistic reasons. There are many trepanned skulls dating back thousands of years to the Neolithic era, and perhaps to even earlier, from sites all over the world.

Background: Myeloid sarcoma (MS) is a rare solid tumour made of myeloblasts or immature myeloid cells in an extramedullary site or in bone, associated with systemic hematologic neoplasms. When they occur in the brain parenchyma, they can often be misdiagnosed. Methods: The authors report a case of a 4-year old boy 6 months out of remission from AML, presenting with a short history of headaches and vomiting, and found to have a heterogenous contrast-enhancing lesion in the right cerebellar hemisphere, with differential diagnosis of myeloid sarcoma, astrocytoma, medulloblastoma and ATRT. Preliminary diagnosis was made flow cytometry from an intraoperative biopsy. The patient had a long course of chemotherapy and radiation, but eventually died from the systemic burden of his AML. Results: The authors present a literature review on 178 published cases of CNS myeloid sarcomas, and their radiological presentation and the basis of immunohistochemical and pathological diagnosis is discussed. Conclusions: Diagnosis rests on a combination of immunohistochemistry and histopathology of biopsied tissue. Surgical resection is controversial, especially given the efficacy of chemotherapy and radiation, and prognosis remains unclear. As with all uncommon and rare clinical entities, further investigation is warranted to determine prognosis and optimal management of CNS myeloid sarcomas.

German neuroscientists played a crucial role in the foundation of neuropsychology. In the 19th century, Gall formulated new assumptions with respect to the nature and localization of mental functions in the brain. Wernicke popularized an approach in which mental functions were represented as networks of centers of more elementary functions. His followers, like Kussmaul, Lissauer and Liepmann, using this approach, created influential theories of aphasia, agnosia, and apraxia. In the 20th century, Goldstein and others opposed to this approach, arguing in favor of a more holistic view of the behavior of brain-injured patients. Many neuropsychological tests originate from assessment and rehabilitation procedures developed in German clinics for brain-injured soldiers. Because of the Nazi regime, individuals like Goldstein, Quadfasel, and Teuber emigrated to the United States and there contributed significantly to the rise of modern neuropsychology. From the 1960s, Poeck played a significant role in the “resurrection” of neuropsychology in Germany.

Over Time

Two key discoveries in the 19th century—infection control and the development of general anesthesia—provided an impetus for the rapid advancement of surgery, especially within the field of neurosurgery. Improvements in anesthesia and perioperative care, in particular, fostered the development of meticulous surgical technique conducive to the refinement of neuroanatomical understanding and optimization of neurosurgical procedures and outcomes. Yet, even dating back to the earliest times, some form of anesthesia or perioperative pain management was used during neurosurgical procedures. Despite a few reports on anesthesia published around the time of William Morton's now-famous public demonstration of ether anesthesia in 1846, relatively little is known or written of early anesthetics in neurosurgery. In the present article the authors discuss the history of anesthesia pertaining to neurosurgical procedures and draw parallels between the refinements and developments in anesthesia care over time with some of the concomitant advances in neurosurgery.

František Palacký (1798–1876), a historian and politician, was one of the most eminent personalities of the Czech society of the 19th century. He died on 26 May 1876 in Prague and on 30 May 1876, in the evening before the burial, the Palacký’s head was dissected and his brain was extracted and preserved as a liquid preparation. Then, it was deposited in the Museum of the Kingdom of Bohemia (present National Museum) in Prague; currently it is stored in a jar concealed in a wall niche of a column (next to a large statue of Palacký) in the Pantheon hall of the historical building of the National Museum on the Wenceslaus square in Prague. The investigation of the Museum archive brought some documents which elucidate certain parts of the history of the Palacký’s brain preparation, although its whereabouts during other periods still remain hidden. For several years after its extraction, the Palacký’s brain was deposited in the Museum library, and between the years 1878–1899 (most probably in 1892 at the latest), it was handed over to the Department of Zoology of the Museum, where it remained until 1931. Next fate of the brain is uncertain until 1958, when it was installed in the wall niche in the Pantheon hall, where it remains till now (with an interruption in the last five years), but again under the responsibility of the Department of Zoology and Department of Anthropology, respectively.

✓ Purified thrombin from an exogenous source is a hemostatic agent commonly used in neurosurgical procedures. The toxicity of thrombin in the brain, however, has not been examined. This study was performed to assess the effect of thrombin on brain parenchyma, using the formation of brain edema as an indicator of injury. Ten µl of test solution was infused stereotactically into the right basal ganglia of rats. The animals were sacrificed 24 hours later, and the extent of brain edema and ion content were measured. Concentrations of human thrombin as low as 1 U/µl resulted in a significant increase in brain water content. Rats receiving 10 U/µl had a mortality rate of 33% compared to no mortality in the groups receiving smaller doses. Thrombin-induced brain edema was inhibited by a specific and potent thrombin inhibitor, hirudin. A medical grade of bovine thrombin commonly used in surgery also caused brain edema when injected at a concentration of 2 U/µl. Edema formation was prevented by another highly specific thrombin inhibitor, Nα-(2-Naphthalenesulfonylglycyl)-4-dl-phenylalaninepiperidide (α-NAPAP). Thrombininduced brain edema was accompanied by increases in brain sodium and chloride contents and a decrease in brain potassium content. Changes in brain ions were inhibited by both hirudin and α-NAPAP, corresponding to the inhibition of brain water accumulation. This study shows that thrombin causes brain edema when infused into the brain at concentrations as low as 1 U/µl, an amount within the range of concentrations used for topical hemostasis in neurosurgery.

abstract BACKGROUND AND IMPORTANCE: Arachnoid cysts have not been reported to be located within the brain parenchyma. We present a case of an arachnoid cyst that was contained entirely within the right frontal lobe devoid of communication with the subarachnoid space and ventricle. CLINICAL PRESENTATION: A 65-year-old woman presented with a 1-year history of progressive headache and nausea. Computed tomographic and magnetic resonance imagining scans showed a well-defined, nonenhancing mass measuring 5 × 5 × 3.5 cm in the right frontal lobe. The mass appeared to be contained entirely within the brain parenchyma. The patient underwent a right frontal craniotomy, at which time the cystic mass was identified in the brain parenchyma without any communication with the arachnoid space. The cyst contained a clear fluid, and its wall was excised. The fluid contents demonstrated a composition similar to that of normal cerebrospinal fluid. Histological and immunohistochemical examinations of the cyst wall were compatible with the diagnosis of an arachnoid cyst. Postoperatively, the symptoms of the patient resolved, and no recurrence was observed up to 6 months after removal. CONCLUSION: The present case showed an intraparenchymal arachnoid cyst arising in the frontal lobe. Although the etiology is not known, an arachnoid cyst should be included in the differential diagnosis of primary intracerebral cysts.

The history of neurosurgery at University of São Paulo comes from 1918, since its origins under the Department of Neurology from Chair of Psychiatric Clinic and Nervous Diseases. Professor Enjolras Vampré was the great inspiration for such medical specialty in the State of Sao Paulo. In 1929, the first neurosurgical procedures were performed in the recently (at time) organized Section of Neurosurgery. The official inauguration of the Division of Functional Neurosurgery occurred at June 1977, with the presence of worldwide well-known neuroscientists. The division suffered a deep streamlining under the leadership of Professor Raul Marino Jr., between the decades of 1990 and 2000. At this time, it was structured with the sections of neurological surgery, functional neurosurgery and neurosurgical emergency. Since 2008, Professor Manoel Jacobsen Teixeira is the Chairman of the Division and has provided the Division with the best available technological resources, performing more than 3,000 surgeries a year and training professionals who will, certainly, be some of the future leaders of brazilian neurosurgery.
