The crucial role of gadolinium-enhanced MRI in a case of amaurosis fugax - a case report and literature review.

Optic perineuritis is the inflammation of the optic nerve sheath. This affliction can lead to visual field impairment and other signs and symptoms related to the orbital space, such as pain, disc edema, ophthalmoplegia, proptosis. However, not all patients present with such suggestive symptoms, requiring a thorough assessment. We report the case of a young male admitted to our hospital for recurrent episodes of monocular blindness. Amaurosis fugax is a well-known presentation of transient ischemic attacks (TIA) and it was ruled out. Gadolinium-enhanced MRI revealed a typical aspect of optic perineuritis. It was mandatory to consider all possible causes of secondary optic perineuritis as they all represent serious clinical conditions, even if the idiopathic form is more frequent. The clinical and paraclinical evaluation of the patient excluded an underlying disease and primary optic perineuritis was diagnosed. Corticosteroid therapy is usually curative and a course of methylprednisolone was initiated for our patient with good outcome. However, response to treatment is not diagnostic as both primary and secondary optic perineuritis are normally responsive, hence thorough differential diagnosis is necessary.

Neuro-Behçet's Disease Onset in the Context of Tuberculous Meningoencephalitis: A Case Report.

Behçet's disease (BD) is a systemic vasculitis that frequently presents with a relapsing-remitting pattern. CNS involvement (Neuro-Behçet) is rare, affecting approximately 10% of patients. Its etiological mechanisms are not yet fully understood. The most commonly accepted hypothesis is that of a systemic inflammatory reaction triggered by an infectious agent or by an autoantigen, such as heat shock protein, in genetically predisposed individuals. Mycobacterium tuberculosis is known to be closely interconnected with BD, both affecting cell-mediated immunity to a certain extent and probably sharing a common genetic background. We present the case of a 34-year-old Caucasian woman who had been diagnosed with tuberculous meningitis 15 months prior, with significant neurological deficits and lesional burden on MRI with repeated relapses whenever treatment withdrawal was attempted. These relapses were initially considered as reactivation of tuberculous meningoencephalitis, and symptoms improved after a combination of antituberculous treatment and corticosteroid therapy. After the second relapse, the diagnosis was reconsidered, as new information emerged about oral and genital aphthous lesions, making us suspect a BD diagnosis. HLA B51 testing was positive, antituberculous treatment was stopped, and the patient was started on high doses of oral Cortisone and Azathioprine. Consequently, the evolution was favorable, with no further relapses and slow improvements in neurological deficits. To our knowledge, this is the first report of Neuro-Behçet's disease onset precipitated by tuberculous meningitis. We include a review of the available literature on this subject. Our case reinforces the fact that Mycobacterium tuberculosis infection can precipitate BD in genetically predisposed patients, and we recommend HLA B51 screening in patients with prolonged or relapsing meningoencephalitis, even if an infectious agent is apparently involved.

Risk factors for the outcome after thrombolysis in acute ischemic stroke - the prominent role of kidney dysfunction: A retrospective cohort observational study.

A complex interplay of factors reflecting the general biological, cardiovascular, neurological, renal, and metabolic status of patients influences the outcome of thrombolysis in stroke patients. This is a retrospective cohort observational study aimed to determine the importance of kidney dysfunction among these factors. Data (demographic, lifestyle, physical examination, laboratory, imaging, including metabolic and cardiovascular risk factors and comorbidities, neurological scores, and outcomes) of all stroke patients who underwent thrombolysis have been registered since January 1, 2016, in an online database. A total of 296 patients registered until December 31, 2020, were included in the study. The National Institutes of Health Stroke Scale, modified Rankin scale, Barthel index, percentage of hemorrhagic transformation, and in hospital death were used to evaluate the neurological status and outcomes of the patients. Regression analysis, Mann-Whitney test, Fisher exact test, logistic regression, and multivariate analysis were used for statistical analysis. Kidney dysfunction, as reflected by the estimated glomerular filtration rate, was associated with in hospital death and all but one of the neurological scores. Other risk factors most frequently associated with neurological scores were age, international normalized ratio, and cognitive decline. Multivariate analysis revealed estimated glomerular filtration rate (as determined by chronic kidney disease-EPI equation) as a determinant for all but one of these scores, and as the most important determinant for most of them, except for those reflecting the pre-intervention neurological status of the patient. Kidney dysfunction seems to be the most important determinant of the outcome of thrombolysed stroke patients, a result obtained by no other study.

Thunderclap headache revealing dural tears with symptomatic intracranial hypotension: Report of two cases.

Cerebrospinal fluid (CSF) leakage is considered the cause of spontaneous intracranial hypotension (SIH), an important etiology for new daily persistent headaches and a potentially life-threatening condition. Minor traumatic events rarely lead to CSF leakage, contrasting with iatrogenic interventions such as a lumbar puncture or spinal surgery, which are commonly complicated by dural tears. Most meningeal lesions are found in the cervicothoracic region, followed by the thoracic region, and rarely in the lumbar region, and extremely rarely in the sacral region. We describe two patients admitted to our hospital for severe headaches aggravated in the orthostatic position, with a recent history of minor trauma and sustained physical effort, respectively. In the first case, a bone fragment pierced an incidental congenital meningocele creating a dural fistula. An extensive extradural CSF collection, spanning the cervicothoracic region (C4-T10), was described in the second case. In both patients, the clinical evolution was favorable under conservative treatment.

Translation of the Fugl-Meyer assessment into Romanian: Transcultural and semantic-linguistic adaptations and clinical validation.

Purpose: The Fugl-Meyer Assessment (FMA) scale, which is widely used and highly recommended, is an appropriate tool for evaluating poststroke sensorimotor and other possible somatic deficits. It is also well-suited for capturing a dynamic rehabilitation process. The aim of this study was to first translate the entire sensorimotor FMA scale into Romanian using the transcultural and semantic-linguistic adaptations of its official afferent protocols and to then validate it using the preliminary clinical evaluation of inter- and intra-rater reliability and relevant concurrent validity. Methods: Through three main steps, we completed a standardized procedure for translating FMA's official afferent evaluation protocols into Romanian and their transcultural and semantic-linguistic adaptation for both the upper and lower extremities. For relevant clinical validation, we evaluated 10 patients after a stroke two times: on days 1 and 2. All patients were evaluated simultaneously by two kinesi-physiotherapists (generically referred to as KFT1 and KFT2) over the course of 2 consecutive days, taking turns in the roles of an examiner and observer, and vice versa (inter-rater). Two scores were therefore obtained and compared for the same patient, i.e., being afferent to an inter-rater assay by comparing the assessment outcomes obtained by the two kinesi-physiotherapists, in between, and respectively, to the intra-rater assay: based on the evaluations of the same kinesi-physiotherapist, in two consecutive days, using a rank-based method (Svensson) for statistical analysis. We also compared our final Romanian version of FMA's official protocols for concurrent validity (Spearman's rank correlation statistical method) to both of the widely available assessment instruments: the Barthel Index (BI) and the modified Rankin scale (mRS). Results: Svensson's method confirmed overall good inter- and intra-rater results for the main parts of the final Romanian version of FMA's evaluation protocols, regarding the percentage of agreement (≥80% on average) and for disagreement: relative position [RP; values outside the interval of (-0.1, 0.1) in only two measurements out of the 56 comparisons we did], relative concentration [RC; values outside the interval of (-0.1, 0.1) in only nine measurements out of the same 56 comparisons done], and relative rank variation [RV; all values within an interval of (0, 0.1) in only five measurements out of the 56 comparisons done]. High correlation values were obtained between the final Romanian version of FMA's evaluation protocols and the BI (ρ = 0.9167; p = 0.0002) for FMA-upper extremity (FMA-UE) total A-D (motor function) with ρ = 0.6319 and for FMA-lower extremity (FMA-LE) total E-F (motor function) with p = 0.0499, and close to the limit, with the mRS (ρ = -0.5937; p = 0.0704) for FMA-UE total A-D (motor function) and (ρ = -0.6615; p = 0.0372) for FMA-LE total E-F (motor function). Conclusions: The final Romanian version of FMA's official evaluation protocols showed good preliminary reliability and validity, which could be thus recommended for use and expected to help improve the standardization of this assessment scale for patients after a stroke in Romania. Furthermore, this endeavor could be added to similar international translation and cross-cultural adaptations, thereby facilitating a more appropriate comparison of the evaluation and outcomes in the management of stroke worldwide.

Multiple cranial nerve palsies following COVID-19 vaccination-Case report.

BACKGROUND: The novel COVID-19 vaccines have side effects that require efficient and close monitoring. AIMS OF THE STUDY: To examine whether the Pfizer-BioNTech vaccine is associated with multiple cranial neuropathy. METHODS: We report the case of a 29-year-old male patient with no notable history who presented with left oculomotor, abducens, trigeminal and facial palsies 6 days after receiving the first dose of the Pfizer-BioNTech COVID-19 vaccine. RESULTS: Gadolinium-enhanced MRI of the brain revealed enhancement in the left facial, trigeminal and oculomotor nerves, which persisted upon repeated examination. The cerebrospinal fluid analysis showed no sign of inflammation, both initially and after 1 month from the start of the patient's symptoms. Other causes were excluded by laboratory tests. The patient received high doses of corticosteroids, with improvement of symptoms. CONCLUSIONS: In our case, the most probable etiology of the patient's multiple cranial neuropathy is the Pfizer-BioNTech vaccine, which highlights the need for prolonged surveillance of COVID-19 vaccine neurological complications.

Aortic Dissection: An Easily Missed Diagnosis when Pain Doesn't Hold the Stage.

BACKGROUND Type A aortic dissection (AD) is a rare disease, with a high mortality rate. Its most common symptom is thoracic pain, which is nevertheless absent in about 6% of cases. Neurologic complications are extremely rare and include ischemic stroke and ischemic neuropathy (which are the most common as presenting symptoms), spinal cord ischemia, and hypoxic encephalopathy. These rare neurological presentations can often be missed at initial clinical examination. CASE REPORT We report 2 cases of patients presenting with seemingly mild neurological symptoms. However, diagnostic tests revealed acute type A AD, and further steps were taken. CONCLUSIONS Although it is a rare cause of transient stroke or peripheral nerve ischemia, AD should be quickly recognized as a potential cause of new-onset neurological manifestations.

Early ST-segment elevation acute myocardial infarction after thrombolytic therapy for acute ischemic stroke: A case report.

RATIONALE: Acute ST-segment elevation myocardial infarction (STEMI) is a rare complication of acute ischemic stroke (AIS) during thrombolytic therapy. We report a case of STEMI occurring 40 minutes after thrombolytic therapy for AIS and discuss the possible mechanisms and therapeutic approaches. PATIENT CONCERNS: A 87-year-old woman with a history of arterial hypertension was admitted for acute onset of right-sided limb weakness 2 hours before arrival at the emergency department. Forty minutes after intravenous recombinant tissue plasminogen activator (i.v. rtPA) administration for AIS, STEMI occurred (signaled by a third-degree atrioventricular block). DIAGNOSES: The diagnoses were AIS and STEMI. Coronary angiography confirmed right coronary artery occlusion. INTERVENTIONS: Four hours after the onset of STEMI, stenting was performed, normalizing the coronary blood flow. OUTCOMES: The patient died 2 days thereafter because of persistent cardiogenic shock. LESSONS: Our case is remarkable owing to the unusually early (<1 hour) occurrence of STEMI after i.v. rtPA administration. A third-degree atrioventricular block after thrombolysis for AIS could signal a STEMI onset. New and ongoing trials are assessing whether adjunct administration of direct thrombin inhibitors of rtPA in the first 24 hours after thrombolysis for AIS can prevent early recurrent ischemic events.

Multiple acute ischemic strokes as the onset manifestation of acute promyelocytic leukemia.

Acute promyelocytic leukemia often manifests with hemorrhagic diathesis, thrombotic events being much rarer. This is the case of a 59-year-old patient with thrombotic cerebro-vascular complications as the onset manifestation of acute promyelocytic leukemia.

Ankle-brachial index and extent of atherothrombosis in 8891 patients with or at risk of vascular disease: results of the international AGATHA study.

AIMS: AGATHA (a Global Atherothrombosis Assessment) was designed to assess the extent of atherothrombosis and the use of the ankle-brachial index (ABI) in vascular patients. The principal hypotheses were that (1) in diseased patients, a low ABI was related to the number and site of vascular beds affected and (2) in at-risk patients without disease, a low ABI was related to the number of risk factors present. METHODS AND RESULTS: Patients were recruited consecutively by 482 clinicians in 24 countries and the ABI measurement was performed at a single visit. Of 8891 patients recruited, 1792 were defined as at risk and 7099 as with disease. Of the with-disease patients, 65.2% had one arterial bed affected, 27.6% two and 7.1% all three. Abnormal ABI (< or =0.9) was present in 30.9% of at-risk and 40.5% of with-disease patients. A lower ABI was weakly associated with an increasing number of risk factors in at-risk patients (r=-0.056, P=0.02) and with the site and number of arterial beds affected in with-disease patients (P<0.001). CONCLUSION: This large international study confirms that atherothrombotic disease often occurs at more than one site. The ABI is related to the risk factor profile and to the site and extent of atherothrombosis.

The current availability of neurological in-patient services in post-communist central and eastern European countries.

BACKGROUND AND PURPOSE: Limited information can be obtained as to the availability of neurological in-patient services in the former communist countries of Eastern and Central Europe. The objective was to analyse data received directly from representatives of the particular countries. METHODS: The data were collected under the auspices of the 'First European Cooperation Neurology Workshop' held in April 2000, in Trest, Czech Republic. Neurologists from 15 post-communist countries provided information from their respective countries. Linear trends in graphs including the reliability value R(2) were used in the analysis of correlations. RESULTS: Data from 14 countries were assembled and trends were analysed. CONCLUSIONS: Direct relationships were found between: (1) the average department size and the average catchment area (R(2) = 0.1015); (2) the percentage of districts with a neurological in-patient department and the gross national product (GNP) per capita (R(2) = 0.1359); (3) the average neurological department size and the GNP per capita (R(2) = 0.1135), and (4) the average length of treatment and the number of neurological beds/100,000 inhabitants (R(2) = 0.1745). Inverse relationships were found between: (1) the number of neurological beds/100,000 inhabitants and the average hospital catchment area (R(2) = 0.2105), and (2) the number of neurological beds/100,000 inhabitants and the GNP per capita (R(2) = 0.1144).
