The expulsion of Augusta Dejerine-Klumpke from the Salpêtrière Hospital: Pierre Marie's revenge.

Augusta Dejerine-Klumpke was ahead of her time, with extensive contributions to the field of neuroanatomy and neurology, achieving international recognition. Despite her great contribution to world neurology, she was expelled from the Salpêtrière hospital in 1917, due to the rivalry and mutual hatred between Pierre Marie and his rival Jules Déjerine, her husband and collaborator.

Treatment of occipital neuralgia using onabotulinum toxin A.

OBJECTIVES: To determine the effectiveness of botulinum toxin in a sample of patients diagnosed with greater occipital nerve neuralgia. MATERIAL AND METHODS: Twenty-nine patients (28 females, 1 male) were treated for greater occipital nerve neuralgia with onabotulinum toxin type A; the Visual Analog Pain Scale was used to determine pain severity at treatment and again 12 weeks after application. RESULTS: Average doses of onabotulinum toxin type A of 18.66±6.44 U per nerve and 35.96±12.89 U per patient were utilized. Average pain severity among the sample was 9.81±0.89 prior to botulinum toxin application and 3.68±2.31 points (p<0.0001) twelve weeks after application. Pain frequency decreased from 29.93±0.37 to 12.17±11.05 days with pain per month (p<0.0001). Six patients reported absence of pain after application (p=0.023). Dose did not correlate with the degree of clinical response observed, and no side effects were reported. CONCLUSION: Our findings suggest onabotulinum toxin type A is a safe and effective treatment alternative for patients suffering from refractory greater occipital nerve neuralgia.

Freezing of gait (FOG) in Parkinson's disease patients-the contribution of Garcin and Melaragno.

Raymond Garcin, professor of neurology in Paris, France, and his Brazilian assistant, Professor Roberto Melaragno described in 1948 the phenomenon defined as "bégaiement de la mise en route du mouvement" in patients with Parkinson's disease. This was one of the first descriptions of freezing of gait (FOG) in the world.

Small vessel occlusion and syphilis in patients with first-ever ischemic stroke.

BACKGROUND: Syphilis is an endemic disease, particularly in low- and middle-income countries, with vascular involvement in large vessels (aortitis), but no clear relationship with stroke patients, except for those who presented with meningovascular neurosyphilis. OBJECTIVE: To investigate the relationship between a positive history of syphilis determined by serological testing and ischemic stroke etiology, particularly small vessel disease (SVD). METHODS: In total, 269 first-ever ischemic stroke patients admitted to the stroke unit were tested for syphilis. Patients with neurosyphilis were excluded. All patients were classified according to the ASCOD phenotyping as SVD - when SVD was the potential causal mechanism (S1) - or non-SVD - when SVD was uncertain (S2), unlike (S3), or not detected (S0). RESULTS: Syphilis was positive in 32 (12%) patients. When comparing patients with positive and negative serology, the only significant difference was SVD as the causal mechanism (S1) in patients with positive results: 9 (28%) vs. 22 (9%), p<0.01. CONCLUSION: The current study showed that the frequency of positive syphilis serological test was higher in patients with first-ever ischemic stroke and SVD as the potential causal mechanism. This finding could be related to the endothelial dysfunction occurring in syphilis.

Roberto Melaragno's scientific contributions to Brazilian Neurology.

Roberto Melaragno Filho, an associate professor of neurology at the School of Medicine of Universidade de São Paulo and head of the neurology service at Hospital do Servidor Público Estadual Francisco Morato Oliveira (HSPE-FMO), had a significant scientific career. He is recognized as a reference in the 20th century Brazilian neurology in addition to having a notable international career.

Autosomal Recessive Cerebellar Ataxia 1: First Case Report Depicting a Variant in SYNE1 Gene in a Chilean Patient.

Autosomal recessive cerebellar ataxia type 1 (ARCA-1) or spinocerebellar ataxia autosomal recessive type 8 (SCAR8) is a slowly progressive neurodegenerative disorder that occurs due to mutations in the spectrin repeat containing nuclear envelope protein 1 (SYNE1) gene. Previously considered a rare cause of ARCA, related to French-Canadian patients from Beauce, Quebec, Canada, SYNE1 ataxia is now known to be of worldwide distribution. We present the case report of a 54-year-old male patient with the genetic diagnosis of SYNE1 ataxia, presenting with a SYNE1 gene mutation never described in Chilean population before.

Follow-Up of Advanced Parkinson's Disease Patients after Clinical or Surgical Emergencies: A Practical Approach.

BACKGROUND: Patients with advanced stage Parkinson's disease (PD) typically present with a myriad of motor and nonmotor symptoms in addition to comorbidities and, as a consequence, polypharmacy. OBJECTIVE: To analyze a series of cases of advanced PD in which a clinical or surgical emergency played a trigger role in the irreversible progression of landmarks of the course of the disease. METHODS: Data were collected during a 13-month observational period of a cohort of 230 PD patients, in 751 medical appointments. We included a total of 13 (5.65% of the total number) patients with advanced PD defined by Hoehn & Yahr (H&Y) stage ≥3 who presented with various clinical and surgical complications which, with the contribution of drug interventions, led to significant worsening of patients' overall clinical condition. RESULTS: Hip fractures and infections were the most common complications identified. As part of this scenario, most patients presented with delirium, often requiring treatment with dopamine receptor blocking agents and/or had dopaminergic treatment withdrawn. Upon reassessment after 3 months, all patients remained bed or wheel chair bound (H&Y 5) and presented significant worsening of their UPDRS part III score of at least 10 points (mean 51.5 ± 3.3; paired t-test two-tailed p < 0.0001 compared to baseline). The mean dose of levodopa at baseline was 907.7 ± 149.8 mg (600-1200) and significantly higher (paired t-test two-tailed p < 0.0001) on follow-up, 1061.5 ± 175.8 mg (700-1300). CONCLUSION: Clinical and surgical emergencies are major determinants for a progression of PD to more advanced stages.

The Duels of Pierre Marie and Jules Dejerine.

In no country has the duel prevailed to such a great extent as in France where the matter of dueling and affairs of honor were of frequent occurrence until the 20th century. The term duel has since been established for any contest between 2 persons or parties, be they sporting, intellectual, political, or in other matters. Despite their worldwide recognition and great scientific production, Pierre Marie and Jules Dejerine became rivals at the end of the 19th century. While Marie defended Charcot's neurological school at Salpêtrière Hospital, Dejerine had his own neurology school to contend. The fierce antagonism between them materialized to the verge of a real death duel in 1892 and later to an intellectual duel in the famous debate about aphasias, held in Paris in 1908.
