CLINICAL PROFILE OF AES CASES IN A TERTIARY CARE CENTER OF NORTH BENGAL

Introduction: The clinical features of Acute Encephalitis syndrome (AES) vary widely across the world and little documentation is available from North Bengal. Materials and methods: A cross –sectional observational study was conducted at the Department of Medicine of a teaching hospital in North Bengal. 104 AES cases were enrolled and clinically evaluated and investigated as per the study protocol. Results:JE (72%) was most common causative agent followed by HSV Encephalitis (11.5%), Scrub Typhus (9.6%) and Dengue Encephalitis (2.88%). Male cases were predominant than female in our study. Fever and altered sensorium were most common presentation followed by seizures (51.9%), headache (29.8%), vomiting (18.2%), and hemiplegia (4.8%). Neurological evaluation revealed 80% of the patients had neck stiffness followed by positive Babinski sign (45.19%) and hypertonia (35%). Conclusions: JE is the commonest cause of AES in North Bengal and seizures are the commonest neurological manifestation after altered sensorium.

The associations between radiological and neurological findings of degenerative cervical myelopathy: radiological analysis based on kinematic CT myelography and evoked potentials of the spinal cord

OBJECTIVE Neurological and imaging findings play significant roles in the diagnosis of degenerative cervical myelopathy (DCM). Consistency between neurological and imaging findings is important for diagnosing DCM. The reasons why neurological findings exhibit varying sensitivity for DCM and their associations with radiological findings are unclear. This study aimed to identify associations between radiological parameters and neurological findings in DCM and elucidate the utility of concordance between imaging and neurological findings for diagnosing DCM. METHODS One hundred twenty-one patients with DCM were enrolled. The Japanese Orthopaedic Association (JOA) score, radiological parameters, MRI and kinematic CT myelography (CTM) parameters, and the affected spinal level (according to multimodal spinal cord evoked potential examinations) were assessed. Kinematic CTM was conducted with neutral positioning or at maximal extension or flexion of the cervical spine. The cross-sectional area (CSA) of the spinal cord, dynamic change in the CSA, C2–7 range of motion, and C2–7 angle were measured. The associations between radiological parameters and hyperreflexia, the Hoffmann reflex, the Babinski sign, and positional sense were analyzed via multiple logistic regression analysis. RESULTS In univariate analyses, the upper- and lower-limb JOA scores were found to be significantly associated with a positive Hoffmann reflex and a positive Babinski sign, respectively. In the multivariate analysis, a positive Hoffmann reflex was associated with a higher MRI grade (p = 0.026, OR 2.23) and a responsible level other than C6–7 (p = 0.0017, OR 0.061). A small CSA during flexion was found to be significantly associated with a positive Babinski sign (p = 0.021, OR 0.90). The presence of ossification of the posterior longitudinal ligament (p = 0.0045, OR 0.31) and a larger C2–7 angle during flexion (p = 0.01, OR 0.89) were significantly associated with abnormal great toe proprioception (GTP). CONCLUSIONS This study found that the Hoffmann reflex is associated with chronic and severe spinal cord compression but not the dynamic factors. The Babinski sign is associated with severe spinal cord compression during neck flexion. The GTP is associated with large cervical lordosis. These imaging features can help us understand the characteristics of the neurological findings.

Professor Faustino Esposel: Neurology, football and spiritualism

ABSTRACT Faustino Monteiro Esposel was a renowned neurologist from Rio de Janeiro, born on October 24, 1888. Together with his mentor, Professor Antônio Austregésilo Rodrigues Lima - the founder of modern Brazilian Neurology -, Professor Esposel described one of the rival signs of the Babinski sign, known as the Austregésilo-Esposel sign, in a study published in the renowned journal L'Encéphale in 1912. This article aims to summarize the life story of this illustrious neurologist as well as to highlight his achievements “beyond medicine”.

Idiopathic myelitis presenting as Brown-Séquard syndrome: two case reports and a review of the literature

Background Brown-Séquard syndrome often occurs in spinal cord injury, and few myelitis patients present with Brown-Séquard syndrome. Case presentation A 33-year-old Han man was admitted with neck pain plus numbness in the right limbs for 2 days and weakness in the left limbs for 1 day. Examination was significant for left limbs with grade 4 muscle power, positive left Babinski sign, diminished vibration sensation in the left limbs and decreased pain below the right clavicle dermatome. The cerebrospinal fluid (CSF) cell count was 24 × 106/L, and the protein count was 185 mg/L. Cervical magnetic resonance imaging (MRI) indicated abnormal swelling signals in the medulla-cervical cord long segment and enhanced signals in the C2-3 region. In the second case, a 47-year-old Han woman was admitted with weakness in the right lower limb and numbness in the left lower limb for more than 20 days. Examination was significant for the right lower limb with grade 4 muscle power, left knee hyperreflexia, positive left Babinski sign, diminished vibration sensation in the right lower limb and decreased pain below the right T2 dermatome. Cervical MRI indicated hyperintense and enhanced signals in the C7-T2 region. In these two cases, CSF culture, oligoclonal band (OB) and aquaporin 4 (AQP4) antibody were negative. Brain MRI was normal. Their symptoms and MRI results improved after treatment with methylprednisolone. Conclusions Myelitis can present as Brown-Séquard syndrome, providing an extended reference in terms of the differential diagnosis for clinical physicians.

PSEUDOTUMORAL PRESENTATION OF NEURO-BEHÇET DISEASE: A CONFUSING DIAGNOSIS

A 35-year-old man was referred to the internal medicine department for acute hemiplegia with oral aphthous ulcers. The patient reported recurrent oral and genital ulcers more than 3 times a year. He also experienced one episode of peripheral thrombosis 1 year ago. The physical examination showed left hemiparesis with positive Babinski sign, hyperreflexia, and pseudofolliculitis in legs and trunk. The pathergy test was positive. Cerebral MRI showed a large mass hyperintense in T2 sequence in the regions of basal ganglia and corpus callosum with peripheral contrast enhancement and intensive edema around the lesion. The diagnosis of pseudotumoral neuro-Behçet disease was made on the basis of clinical history, the cerebral MRI result, and the exclusion of other tumoral and infectious diseases. The patient was treated with corticosteroids and cyclophosphamide with favorable outcome.

Case Report: Thalamomesencephalic stroke in a patient with HIV

We present a 41-year-old HIV-positive female patient complaining of complete right palpebral ptosis, diplopia, and inability to balance herself. On examination, the right eye was able to move laterally and downwards. The motor exam showed left hemiparesis (4/5) on upper and lower limbs, bilateral Babinski sign with left hemiataxia without the sensory disorder. CT scan and magnetic resonance imaging angiography demonstrated an ischemic infarct on the right paramedian branch of the posterior cerebral artery territory. This patient did not present clinical manifestations of the thalamic lesion. To our knowledge, this is the first reported case of a young patient presenting a unilateral thalamomesencephalic ischemic stroke secondary to HIV vasculitis with bilateral Babinski signs and without thalamic signs in the medical literature.

The Babinski sign in Renaissance paintings—a reappraisal of the toe phenomenon in representations of the Christ Child: observational analysis

Objective To investigate systematically the presence of the Babinski sign in paintings of the Christ Child by the greatest painters of the Renaissance. Design Observational analysis. Setting Large collection of paintings depicting the Christ Child from Flemish, Rhenish, and Italian schools between 1400 and 1550 CE, searched using published catalogues and Google. Study sample 302 Renaissance paintings (by 19 painters) depicting the Christ Child. Main outcome measure Babinski sign, defined as a hallux extension with an amplitude greater than 30°. The presence of foot sole stimulation was also noted. Results An unquestionable upgoing toe was apparent in 90 (30%) of the 302 paintings. The Babinski sign was present in more than 60% of Christ Child paintings by Rogier van der Weyden, Hans Memling, Martin Schongauer, and Matthias Grünewald. A bilateral Babinski sign was observed in three paintings. Stimulation of the sole was noted in 48/90 (53%) paintings and was always present in paintings by Andrea del Verrocchio, Leonardo da Vinci, and Giorgione. No association existed between the presence of the Babinski sign and the period during which the painter was active. Conclusions Four main factors were noted in relation to the representation of the Babinski sign in paintings of the Christ Child: the physiological toe phenomenon in infants, the representation of the nudity of the Christ by painters during the 15th century to demonstrate the incarnation, Renaissance painters’ need for precise observation of anatomy, and the desire of some Rhenish and Flemish painters to depict very realistic details. Italian Renaissance painters, whether Mannerist or not, tended to idealise the beauty of human body, and they often did not reproduce the Babinski sign.
