RESUMO
INTRODUCTION: Allgrove syndrome is a genetic disorder characterized by a multisystem involvement manifesting mainly in childhood with esophageal achalasia, adrenal insufficiency, and alacrima. Associated neurological manifestations are frequent in patients with late-onset forms and include peripheral, central, and autonomic dysfunction. The definitive diagnosis remains genetic, but neurological symptoms/signs could be a relevant clue for the diagnosis. DISCUSSION: This syndrome is rare, but it is not impossible for it to occur in adults, so all neurologists must be alert. Moreover, in this regard, neurological symptoms can sometimes be very similar to those of motor neuron disease patients, so that, although rare, Allgrove syndrome may also enter into the differential diagnosis with the bulbar variant of amyotrophic lateral sclerosis. Nevertheless, attention to extra-neurological symptoms must remain high as these play an equally important role in reaching the diagnosis. CASE REPORT: Here we present the case of a patient with some peculiarities that are onset at an advanced age, genetic confirmation of the diagnosis, and prominent neurological involvement, which also opens the differential diagnosis to amyotrophic lateral sclerosis.

BACKGROUND: In 2017, the European Association of Neuro-Oncology (EANO) published the guideline for palliative care in adults with glioma. The Italian Society of Neurology (SIN), the Italian Society for Palliative Care (SICP), and the Italian Association for Neuro-Oncology (AINO) joined forces to update the guideline, and adapt it to the Italian context. AIM: We involved patients, caregivers, and (herein presented) healthcare professionals (HPs) in the formulation of the guideline clinical questions. DESIGN AND PARTICIPANTS: Online survey of Italian HPs experienced in the care of patients with glioma. Participants rated the importance of 14 pre-specified intervention topics on a 0/10 scale and gave their free comments. RESULTS: Of 244 participants, 149 (61%) were palliative medicine (PM) HPs and 95 Neuro HPs. Their mean age was 48.9 years, 63% were women, and 48% had over 12 years of experience in the care of glioma patients. Physicians were 68%, followed by nurses (28%), psychologists (7%), therapists (3%), and social workers (2%). Most HPs rated the pre-specified topics as important (score ≥ 7) or critical (score ≥ 9), with some differences between PM and Neuro HP groups. There were 58 free comments: 46 (78%) on nine pre-specified topics, and 13 on four new topics, three of which were guideline-pertinent ("caregiver's support and education"; "family physician's training in neuro-oncology"; and "PM HPs' training in neuro-oncology"). CONCLUSIONS: Participation in the survey was high and information-rich, between-group rating differences reflecting HP background. Participants endorsed the 14 intervention topics devised by the guideline panel and identified three additional topics.

BACKGROUND: In 2017, the European Association for Neuro-Oncology (EANO) published the guideline for palliative care (PC) in adults with glioma. The Italian Society of Neurology (SIN), the Italian Association for Neuro-Oncology (AINO), and the Italian Society for Palliative Care (SICP) joined forces to update and adapt this guideline to the Italian context and aimed to involve patients and carers in the formulation of the clinical questions. METHODS: During semi-structured interviews with glioma patients and focus group meetings (FGMs) with family carers of deceased patients, participants rated the importance of a set of pre-specified intervention topics, shared their experience, and suggested additional topics. Interviews and FGMs were audio-recorded, transcribed, coded, and analyzed (framework and content analysis). RESULTS: We held 20 interviews and five FGMs (28 carers). Both parties considered the pre-specified topics as important, chiefly information/communication, psychological support, symptoms management, and rehabilitation. Patients aired the impact of focal neurological and cognitive deficits. Carers reported difficulties in dealing with patient's behavior and personality changes and appreciated the preservation of patient's functioning via rehabilitation. Both affirmed the importance of a dedicated healthcare path and patient's involvement in the decision-making process. Carers expressed the need to be educated and supported in their caregiving role. CONCLUSIONS: Interviews and FGMs were well informative and emotionally challenging. Both parties confirmed the importance of the pre-specified topics, and carers suggested one additional topic: education/support to caregivers. Our findings strengthen the importance of a comprehensive care approach and of addressing the needs of both patients and their family carers.

I n the context of an adequate health care organization, the figure of the neurologist as an emergency operator (in the emergency room-ER-and/or in a dedicated outpatient clinic) is crucial for an effective functional connection with the territory (and therefore with general practitioners), a reduction in inappropriate ER accesses, specific diagnostic and therapeutic approaches to neurological emergencies in the ER and a reduction in nonspecific or even unnecessary instrumental investigations. In this position paper of the Italian Association of Emergency Neurology (ANEU: Associazione Neurologia dell'Emergenza Urgenza), these issues are addressed, and two important organizational solutions are proposed: 1) The Neuro Fast Track, as an outpatient organization approach strongly linked to general practitioners and non-neurological specialists and dedicated to cases with deferrable urgency (to be assessed within 72 h) 2) The identification of an emergency neurologist, who is engaged in ER assessments as a consultant and involved in the management of the semi-intensive care unit of the emergency neurology and the stroke unit according to an appropriate rotation, as well as in consultations for patients with neurological emergencies in inpatient wards The possibility of computerizing the screening of patients with deferrable urgency in the Neuro Fast Track is described. A dedicated app represents an important tool that can facilitate the identification of patients for whom deferred assessment is appropriate, the scheduling of neurological examinations and reductions in the booking time through a more rapid approach to specialist assessment and subsequent investigations.

OBJECTIVE: To estimate the incidence and describe clinical characteristics and outcome of GBS in COVID-19 patients (COVID19-GBS) in one of the most hit regions during the first pandemic wave, Lombardia. METHODS: Adult patients admitted to 20 Neurological Units between 1/3-30/4/2020 with COVID19-GBS were included as part of a multi-center study organized by the Italian society of Hospital Neuroscience (SNO). RESULTS: Thirty-eight COVID19-GBS patients had a mean age of 60.7 years and male frequency of 86.8%. CSF albuminocytological dissociation was detected in 71.4%, and PCR for SARS-CoV-2 was negative in 19 tested patients. Based on neurophysiology, 81.8% of patients had a diagnosis of AIDP, 12.1% of AMSAN, and 6.1% of AMAN. The course was favorable in 76.3% of patients, stable in 10.5%, while 13.2% worsened, of which 3 died. The estimated occurrence rate in Lombardia ranges from 0.5 to 0.05 GBS cases per 1000 COVID-19 infections depending on whether you consider positive cases or estimated seropositive cases. When we compared GBS cases with the pre-pandemic period, we found a reduction of cases from 165 to 135 cases in the 2-month study period in Lombardia. CONCLUSIONS: We detected an increased incidence of GBS in COVID-19 patients which can reflect a higher risk of GBS in COVID-19 patients and a reduction of GBS events during the pandemic period possibly due to a lower spread of more common respiratory infectious diseases determined by an increased use of preventive measures.

BACKGROUND: Heart failure (HF) is the second most important cardiac risk factor for stroke after atrial fibrillation (AF). Few data are available on mechanical thrombectomy (MT) in acute ischemic stroke (AIS) patients with HF. METHODS: The source of data is the multicentre Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS). All AIS patients ≥ 18 years receiving MT were categorised in two groups: HF and no-HF. Baseline clinical and neuroradiological findings on admission were analysed. RESULTS: Of 8924 patients, 642 (7.2%) had HF. Compared to the no-HF group, HF patients had higher prevalence of cardiovascular risk factors. Rate of complete recanalisation (TICI 2b-3) was 76.9% in HF vs 78.1% in no-HF group (p = 0.481). Rate of symptomatic intracerebral haemorrhage at 24-h non-contrast computed tomography (NCCT) was 7.6% in HF vs 8.3% in no-HF patients (p = 0.520). At 3 months, 36.4% of HF patients and 48.2% of no-HF patients (p < 0.001) had mRS 0-2, and mortality was, respectively, 30.7% and 18.5% (p < 0.001). In multivariate logistic regression, HF was independently associated with mortality at 3 months (OR 1.53, 1.24-1.88 95% CI, p < 0.001). In multivariate ordinal regression, HF patients had a probability of transitioning to a higher mRS level of 1.23 (1.05-1.44 95% CI, p = 0.012). The propensity score analysis of two groups matched for age, sex, and NIHSS at admission yielded the same results. CONCLUSION: MT is safe and effective in HF patients with AIS. Patients with HF and AIS suffered from higher 3-month mortality and unfavourable outcome regardless of acute treatments.

BACKGROUND: The assessment of human and diagnostic resources is a prerequisite to improving the management of emergency neurology. OBJECTIVE: To provide a landscape on the organization of the Lombardy Region hospitals for emergency neurological care management. METHODS: We designed an anonymized questionnaire including 6 sections with 21 questions on facilities, human and diagnostic resources, and intra- and between-hospital connections. The time needed to fill the questionnaire was estimated not to exceed 6 min. RESULTS: The questionnaire was returned by 33/41 (80.5%) hospitals, 22 classified as level 1 (spoke), and 11 as level 2 (hub). Five of 33 (15%) did not have a neurology unit. The mean annual rate of neurological consultations accounted for 5-6% of all admissions (range 2-8%) and did not differ between levels 1 and 2 hospitals. Neurologists were 24-h available in 21/33 (64%) hospitals, 12-h and on call at night in 6 (18%), less than 12 h without nocturnal availability in 5 (15%), and neither present nor available in 1 (3%). Brain CT and CSF examinations were 24-h universally available, whereas EEG and neurosonology were not in most hospitals. Despite angio-CT was 24-h available in more than 75% of the hospitals, only 45% of them had 24-h availability of diffusion/perfusion imaging, and 43% were not available at any time. Only 12% of the hospitals had 24-h availability of neuroradiologists and 6% of interventional neuroradiologists. CONCLUSION: Our data, while emphasizing current critical issues, offer clues for identifying priorities and improving the management of emergency and time-dependent neurological diseases.

Glioblastoma multiforme (GBM) is considered the most malignant form of primary brain tumor. Despite multimodal treatment, prognosis remains poor. Ketogenic diet (KD) has been suggested for the treatment of GBM. In this study, the syngenic, orthotopic GL261 mouse glioma model was used to evaluate the effects of KD on the metabolic responses of the tumor using 7T magnetic resonance imaging/spectroscopy. GL261 cells were injected into the caudate nucleus of mice. Following implantation, animals were fed with standard chow or underwent a KD. 18 days after initiating the diet, mice fed with KD displayed significantly higher plasmatic levels of ketone bodies and survived longer than those fed with the standard diet. Decreased concentrations of gamma-aminobutyric acid, N-Acetyl-Aspartate and N-acetylaspartylglutamate were found in tumor tissue after 9 days into the KD, while a huge increase in beta-hydroxybutyrate (bHB) was detected in tumor tissue as compared to normal brain. The accumulation of bHB in the tumor tissue in mice undergoing the KD, may suggest either elevated uptake/release of bHB by tumor cells, or the inability of tumor cells in this context to use it for mitochondrial metabolism.

INTRODUCTION: Mutations of the skeletal muscle sodium channel gene SCN4A are associated with several neuromuscular disorders including hyper/hypokaliemic periodic paralysis, paramyotonia congenita and sodium channel myotonia. These disorders are distinguished from dystrophic myotonias by the absence of progressive weakness and extramuscular systemic involvement. METHODS: We present an Italian family with 2 subjects carrying a p.Asn1180Ile mutation in SCN4A gene showing a peculiar clinical picture characterized by the association of myopathic features and myotonia. RESULTS: The clinical, electromyographic and histological findings of these patients are reported. The possible pathogenicity of the mutation was tested by three different software, all giving positive results. DISCUSSION: This is the first report of a dominant, heterozygous mutation in SCN4A causing a complex phenotype of non-congenital myopathy and myotonic syndrome. We suggest that, in patients with myotonia and myopathy not related to dystrophic myotonias, the sequence analysis of SCN4A gene should be performed.

INTRODUCTION: Contrast-induced encephalopathy is a rare and usually reversible entity due to the administration of iodinated contrast. Clinical manifestations include cortical blindness, encephalopathy, seizures and focal neurological deficits. METHODS: We report the case of a 56-year-old woman who developed global aphasia and right hemiplegia after a cerebral angiography performed for a subarachnoid haemorrhage. A prompt brain MRI resulted negative, while CT scan revealed left cerebral oedema with the cerebral sulci effacement. Complete recovery was observed in 10 days. DISCUSSION: Diagnosis of contrast-induced encephalopathy requires a temporal correlation between neurological dysfunction and administration of iodinated contrast. Usually, the symptomatology is transient with a full recovery within 48-72 h. The most common symptom is cortical blindness, while other symptoms have been rarely reported. Only 20 cases previously reported global aphasia and/or hemiplegia or mimed anterior circulation strokes. Prompt brain neuroimaging is essential in order to exclude an alternative diagnosis that requires a distinct therapeutic approach.

BACKGROUND AND PURPOSE: Adult brainstem gliomas are rare primary brain tumours with heterogeneous clinical course. The low frequency of these tumours makes it difficult to achieve high-quality evidence regarding prognostic factors, adequate therapeutic approach and outcome in such patients. METHODS: In this retrospective study, we analysed clinical, radiological, molecular, prognostic and therapeutic factors in a series of 47 histologically proven adult brainstem gliomas recruited over a 20-year period (1998-2018). RESULTS: Twenty-two patients were male, 25 female with median age of 39 years. The tumour involved one brainstem segment in 20 cases and 2 or more segments in 27. Contrast enhancement was reported in 28 cases. Surgical procedures included biopsy in 26 cases and partial/total resection in the remaining 21. Histological diagnosis was of low-grade glioma in 23 patients, high-grade glioma in 22 and non-diagnostic in 2 cases. Data regarding molecular biology were available for 22 patients. Median overall survival was 35 months, in particular 16 months in high-grade glioma and 84 months in low-grade glioma. At univariate analysis, tumour grade was the only factor with a statistically significant impact on survival time (p = 0,003), whereas younger age, better performance status and total/subtotal resection showed a trend to more prolonged survival. This study also confirms safety of biopsy/surgery in adult brainstem glioma patients and shows a clear trend to a more frequent assessment of molecular biology data. CONCLUSIONS: Further prospective multicentre efforts, and hopefully clinical trials, are necessary to improve outcome in this neglected glioma patient population.

INTRODUCTION: Medulloblastoma (MB) is the most common primary malignant intracranial tumor in childhood, but it is very rare in adults, and for this reason, the optimal treatment has not yet been defined. We designed a multicentric study in order to define relevant outcome measures for future prospective studies. MATERIALS AND METHODS: The project involved 10 Italian centers. The database shared among the centers contains epidemiological, diagnostic (radiological and histological/molecular), therapeutic, recurrence information, and survival data. RESULTS: A total of 152 patients (102 males and 50 females, median age 32) were included in the study. Twenty-three of 152 patients had a diagnosis of classic medulloblastoma, 52/152 had desmoplastic/extensive nodularity, 2/152 had large-cell anaplastic medulloblastoma, and the remaining had diagnoses not otherwise specified. Almost all patients underwent craniospinal irradiation after surgery; in 85.5% of patients, adjuvant chemotherapy, mainly platinum- and etoposide-based chemotherapy, was performed immediately after RT. Upon recurrence, most patients were retreated with various chemotherapy regimens, including intrathecal chemotherapy in patients with leptomeningeal dissemination. The overall survival (OS) rate at 5 years was 73.3% (95% CI, 65.0-80.0%). The median OS for the whole group of patients was 112 months. CONCLUSIONS: The data collected were mainly consistent with the literature. A limitation of this study was the large number of patients lost to follow-up and the lack of molecular data for most patients diagnosed until 2010. An important challenge for the future will be MB biologic characterization in adults, with the identification of specific genetic patterns. It will be important to have more national and international collaborations to provide evidence-based management strategies that attempt to obtain a standard of care.

INTRODUCTION: Nowadays, reports of beriberi are rare in developed countries. Wernicke encephalopathy may be present in about 25% of patients with beriberi. CASE REPORT: We report the case of a woman with history of depression and chronic eating disorder, who complained Wernicke encephalopathy and beriberi. Sural nerve and muscular biopsy were performed, showing severe axonal neuropathy. Thiamine supplementation was started with rapid improvement of the pulmonary and cardiac affections; improvement of peripheral neuropathy was incomplete. CONCLUSIONS: Thiamine deficiency can be misdiagnosed. Beriberi is an important cause of acute flaccid paralysis; hence, clinicians should consider this diagnosis and prompt start thiamine treatment to avoid permanent neurological sequelae.

We present the case of an immunocompetent 55-year-old woman, treated with corticosteroids, developing a cerebral fungal infection with autoptic ascertainment of aspergillosis and mucormycosis. This is the first report of cerebral co-infection by mucorales and aspergillus in an immunocompetent host. A possible explanation is that corticosteroids, even if taken for a short time, led to a transient lowering of immune function and contributed to negative outcome.

Herpes simplex encephalitis relapses have been rarely reported, with only few cases occurring after neurosurgical interventions. A young man presented a late herpes simplex encephalitis relapse after left antero-mesial temporal resection for his refractory temporal lobe epilepsy. Eight days after surgery, he developed fever and aphasia. CSF PCR revealed more than 12,000 copies/ml of HSV-1 DNA. Intravenous acyclovir was immediately started with a complete recovery. Postoperative herpes simplex encephalitis can occur as primary infection or as relapse of previous infection. Surgical manipulation of brain parenchyma in the site of a previous infection can act as a trigger for viral reactivation. Early onset of antiviral therapy is fundamental and it is a strong predictor of clinical outcome. Despite no studies on prophylactic treatment with acyclovir in patients with previous herpes simplex encephalitis candidate to neurosurgery are available, we suggest that prophylactic treatment should be recommended.

RESUMO
Headache has been consistently reported as the most common symptom of cerebral venous thrombosis and as the most frequent presenting feature. It is often the heralding symptom, preceding other manifestations of the disease by days or even weeks. This aspect highlights the importance of recognizing headache due to cerebral venous thrombosis, as early recognition of the disease can lead to a rapid diagnosis with appropriate imaging techniques and as early treatment with heparin can dramatically change the course of the disease and alter the prognosis. Unfortunately, although common, the headache has no specific features, and the clinical presentation of CVT is highly variable, making the correct diagnosis in the emergency setting a challenging task for clinicians, even in the case of highly specialized ones such as neurologists. In this review, we will briefly summarize the epidemiology and physiopathology of CVT, and then we will discuss in more details the causes, features, and course of headache, focusing on its relevance for differential diagnosis and on red flags that should suggest the possibility of CVT as the cause of the headache.

The sudden worldwide outbreak of Coronavirus Disease 2019 (COVID-19) has certainly provided new challenges in the management of acute ischaemic stroke, and the risk-benefit ratio of intravenous thrombolysis in COVID-19 positive patients is not well known. We describe four COVID-19 patients treated with intravenous thrombolysis for acute ischaemic stroke. Although rt-PA administration is the main therapeutic strategy, our patients experienced unpredictable complications and showed atypical features: the overall mortality was very high. In conclusion, in this article, we provide information about these cases and discuss the possible explanation behind this trend.

INTRODUCTION: During surgery for lesions in eloquent areas the goal is to achieve the widest resection possible, without loss of neurological function. Intraoperative seizures may lead to abandonment of the procedure or damages to the patient. Awareness regarding the predictors of IOS would help the surgeon. The aim of this retrospective study was to identify the factors associated with the occurrence of IOS in patients who underwent awake surgery for removal of gliomas in eloquent areas. METHODS: This was a retrospective analysis of prospectively collected data of 109 patients who underwent awake craniotomy between January 2010 and December 2017 for removal of gliomas. IOS were defined as tonic-clonic seizures or loss of consciousness resulting in communication difficulties with the patient occurring during cortical and subcortical mapping. RESULTS: A total of 109 patients were included in this study and IOS occurred in 9 (8.2%) patients. Demographic and clinical factors were comparable between patients with and without IOS. In the IOS group, 7 (77.8%) patients had seizures preoperatively and 4 (57.1%) were on more than one perioperative antiepileptic drugs (AED). CONCLUSIONS: The current series add some hints to the poorly studied IOS risk during awake surgery. The risk of IOS appears to be relatively higher in patients with anteriorly located tumors and in patients operated without intraoperative brain activity monitoring and different patterns of stimulation for language and sensory-motor mapping. Further studies are needed to clarify the role of intraoperative techniques.

BACKGROUND AND PURPOSE: Glioblastoma (GBM) is the most aggressive and frequent subtype of all malignant gliomas. At the time of recurrence, therapeutic options are lacking. Ortataxel, a second-generation taxane was reported to be effective in pre-clinical and phase I clinical studies. The aim of this study was to evaluate a potential therapeutic activity of ortataxel in patients with GBM recurring after surgery and first line treatment. METHODS: In this phase II study, according to a two stage design, adult patients with histologically confirmed GBM in recurrence after surgery or biopsy, standard radiotherapy and chemotherapy with temozolomide were considered eligible. Patients included were treated with ortataxel 75 mg/m2 i.v. every 3 weeks until disease progression. The primary objective of the study was to evaluate the activity of ortataxel in terms of progression free survival (PFS) at 6 months after the enrollment. PFS, overall survival at 9 months after the enrollment, objective response rate, compliance and safety were evaluated as secondary endpoints. RESULTS: Between Nov 26, 2013 and Dec 12, 2015, 40 patients were recruited across six centres. The number of patients alive and free from progression at 6 months after the enrollment, observed in the first stage was four (11.4%), out of 35 patients included in the analysis, below the minimum number of events (7 out of 33) required to continue the study with the second stage The most important toxicities were neutropenia and hepatotoxicity that occurred in 13.2% of patients and leukopenia that occurred in 15.8% of patients. CONCLUSION: Overall ortataxel treatment fail to demonstrate a significant activity in recurrent GBM patients. However in a limited number of patients the drug produced a benefit that lasted for a long time. TRIAL REGISTRATION: This study is registered with ClinicalTrials.gov, number NCT01989884.
