ABSTRACTS Papers for BC Roy Gold Medal Award 1.ANTI TPO RELATED ENCEPHALOPATHY Synmon Baiakmenlang , Basumatary LJ*, Das M**, Goswami M ***, Kayal A K ***. Department of Neurology, Guahati Medical College and Hospital, Guwahati, India INTRODUCTION: Presence of antithyroid peroxidase antibody (anti TPO) in a patient of encephalopathy or other related clinical features brings a possibility of autoimmune encephalopathy classically known as Hashimoto encephalopathy (HE), but this antibody may be found in cases not typical of HE. Response to steroids clinches its diagnosis; hence it has been labeled as ‘steroid responsive encephalopathy’ (SRE). OBJECTIVES: To study clinical manifestations who presented with encephalopathy with positive anti TPO antibodies, and response to steroids. METHODS: Observational study conducted from September 2013 – September 2014 Detailed neurological evaluation, biochemistry, thyroid function test, anti TPO level, CSF study, EEG and neuro-imaging were performed. Patients were treated with steroid and followed up. RESULTS: Total 10 patients were enrolled. The age of presentation ranged from 4th to 7th decade, with male predominance (7:3). Clinical manifestation included dementia (4), behavioral abnormality (4), delirium (4), myoclonus (2), sleep disturbance (2), seizure (1) and depression (1). Pyramidal & extrapyramidal features were observed in 3 & 1 patient respectively. Regarding thyroid status, hyperthyroid (2), hypothyroid (1), euthyroid (7) and active thyroiditis was found in 2 patients. The highest level of anti TPO found was 1300 in serum. Steroid (pulse therapy) was given to 7 patients with a good response in 5 patients and a relapse in two. Based on Chong criteria, 4 patients were labeled as HE and the others as anti TPO related encephalopathy. CONCLUSION: All anti TPO positive encephalopathy do not classically fit as HE, but should not be missed out as many of them shows a dramatic response to steroids. Key words: Anti TPO, Hashimoto encephalopathy, steroid responsive encephalopathy TITLE : “ Clinical features of Huntington’s disease and correlation of clinical features with genetic study in tertiary care centre in Eastern India” Dr Zakir Hussain, PG Student,IGPMER SSKM Hospital Kolkata INTRODUCTION : Huntington’s disease HD is a progressive degenerative disorder of the central nervous system with autosomal dominant inheritance characterized by involuntary movements, cognitive impairment and behavioral disturbances. HD is associated with an expanded sequence of CAG repeats on the IT15 gene that is located on chromosome 4. Materials and methods : Herein, we report clinical data on 20 genetically confirmed HD patients from 17 Indian families predominantly from North East India. Clinical data and evaluation was performed using standardized formats used by the Huntington Disease Study Group. Results : Adult onset HD was commonest while .Juvenile HD onset - 20 years was observed in ; 10% of patients. Chorea was the commonest presenting symptom (n17, 85%) while remaining presented with psychiatric symptoms (n3, 15%) . Impairment of saccades was observed in 75% of patients. Mean (SD) CAG repeats in the abnormal allele was 47.8 (8.7) . Total motor score but not the total behavioral score worsens with duration of symptoms. The functional checklist score correlates with total motor score rather than with duration of symptoms. Conclusions: We detail clinical characteristics in genetically confirmed HD patients from a predominantly North East Indian cohort. We observed a slightly higher occurrence of Juvenile HD. Functional disabilities in our patients correlate with worsening of motor rather than behavioral symptoms. 3.TITLE :CLINICORADIOLOGICAL ANALYSIS AND OUTCOME STUDY OF TRAUMATIC INTRACRANIAL EPIDURAL HEMATOMAS IN PEDIATERIC POPULATION. Presenting Author: Waqar Ahmad Co Author: Dr C B Sahay, Dr Thomas J Minz, Prof Anil Kumar Institution : Department of Neurosurgery, Rajendra Institute of Medical Sciences ABSTRACT : AIM :Theaims of this analysis were to review the cause and outcome of pediatricEpidural Hematoma(EDH) and to discuss criteria of medical/surgical management & outcome-related variables. BACKGROUND :Traumatic head injury is a common cause of mortality and acquired neurological impairment in children. Pediatric EDHconstitute a distinct subgroup of head injury in pediatric population. METHODS :A series of 90 children (below 16 years of age )withEDH treated at the Department of Neurosurgery , RIMS , Ranchi between July 2011 and August 2014 were analysedin detail. Clinical course, radiological findings and outcomes were evaluated. Computed Tomography(CT) scan constituteda valuable tool for an early and correct diagnosis apart from Magnetic resonance imaging(MRI) in few. Patients’ medical records, CT scans were reviewed to define variablesassociated with outcome. Management &Outcome Variables included in the analysis were age of patient,time-lapsed, mode of injury, signs & symptoms, associatedextracranial and/or intradural injury, abnormal pupillary response, lucid interval,hematomalocation &volume, Child coma scale at time of admission and diffuse axonal injury. RESULTS:The most common symptoms werevomiting (78%, n=70) loss of consciousness (72%, n=65) , headache & irritability( 67%, n=60). The most frequent mechanisms of injury was fall from a height(64%, n=58).Barring a few cases( 10% ,n=9)who underwent medical management( vol< 25 ml with <5 mm midlineshift& GCS >9), most were treated surgically( 90%, n=81).Overall mortality was 5.5%(n=5).The mean follow-up was six months. CONCLUSION:The outcome& management protocolwas found to be predominantly affected by the preoperative neurological status,by the duration of the time interval between injury & onset of neurological deterioration, and mainly by the presence of associated brain lesions. 4.MEDULLOBLASTOMA: A NEW CLINICO-IMMUNO-HISTOPATHOLOGICAL CLASSIFICATION: IS IT REQUIRED? Ravi Shankar1, Medha Tatke2, Ajay Sharma2 Jaypee Hospital, Noida & 2 G.B. Pant Hospital, New Delhi. 1 Aim: Medulloblastoma, one of the common brain tumors of childhood has been prognosticated on the basis of Chang’s classification system for a long time. However with the advent of new factors, we propose a new classification system based on combination of various prognostic factors. Material & Method: In a consecutive series of 63 patients operated for medulloblastoma over a period of three years, overall outcome was studied in reference to a set of various clinicoimmuno-histopathological features. Result: The mean age of 63 cases at presentation was 11.6 yrs with 39 males and 24 females (M: F = 1.6:1) and mean duration of symptoms was 14.14 weeks with first symptom being headache in 76.2% (48/63) of patients. Majority of the tumors was vermian (87%; 55/63). VP shunt prior to definitive surgery was done in 28% (18/63) cases. Near/ gross total resection was achieved in 74.6% (47/63) of the cases. All, except 5 patients completed radiotherapy while 52% (33/63) completed chemotherapy. The most common variant was classical (68.3%; 43/63) followed by the desmoplastic variant (22.2%; 14/63) and large cell/anaplastic variants each comprised (4.8%; 3 cases each/63). GFAP was positive in 54 % (34/63) of the cases. Synaptophysin was positive in 81 % (51/63) of the cases & the mean MIB-LI of the 63 cases was 20.59 ± 7.86 (range 8-40). The median duration of follow up was 41 month (Mean: 45 months; range 1-130 months) with 33 (52.4%) documented recurrence with 13 mortality (20.6%). Conclusion: Classical medulloblastoma had a better prognosis than the desmoplastic variant with LC/A variants having the worse prognosis. Severity of nuclear atypia (p – 0.08), presence of mitotic/ apoptotic figures in sheets (p – 0.01), presence of necrosis (p – 0.03), endothelial proliferation (p – 0.08) & MIB > 20 are associated with increased recurrence rates. Extent of resection (p – 0.004), chemotherapy (p – 0.02), and presence of gross anaplasia (p – 0.03), are the most important and independent predictors of recurrence rates. 5.Title of Paper - “Caregiver burden of dementia: correlation with stages of dementia and behavioral and psychological symptoms of dementia” Presenting Author- Adreesh Mukherjee Qualification- MBBS, MD (Medicine), DM PDT (Neurology) Co-authors- Atanu Biswas, Arijit Roy Place of work- Department of Neurology, Bangur Institute of Neurosciences, Kolkata Title/Position- DM PDT (Neurology) ABSTRACT Objective- To evaluate caregiver burden (CB) of dementia alongwith the correlation between caregiver burden with stages of dementia and behavioral and psychological symptoms of dementia (BPSD). Methods- Study population consisted of 20 consecutive patients of dementia and their caregivers. Dementia was diagnosed by DSM-IV criteria. Patients were assessed using structured proforma of cognitive clinic of Bangur Institute of Neurosciences. Staging was done by Clinical Dementia Rating (CDR) scale. Standard criteria were used to delineate types of dementias. BPSD were assessed with Neuropsychiatric Inventory (NPI). CB was evaluated with Zarit Burden Interview (BI). Results- Of the 20 patients included in the study, 14 were male and 6 female. Average age of patients was 66.2 years. 12 patients had Alzheimer Disease, 3 had Mixed dementia, 3 Frontotemporal Dementia, 1 Vascular dementia, 1 Dementia with Lewy Bodies. Average BI scores in Global-CDR groups were 11.5 for CDR-0.5, 37.9 for CDR-1, 57 for CDR-2 and 54 for CDR-3. Total NPI scores were: 3.3 for little-or-no burden, 19.7 for mild-to-moderate burden, 24.9 for moderate-to-severe burden, 41.2 for severe burden, respectively. CDR- sum of boxes scores were: 3.3 for little-or-no burden, 6.7 for mild-to-moderate burden, 13 for moderate-tosevere burden, 13.4 for severe burden, respectively. Conclusions- CB was more with increasing severity of dementia. However, moderate-to-severe and severe burden groups had similar severity of dementia. Behavioral and psychological symptoms of dementia have immense effect on the caregiver burden; especially in moderate to severe dementia it seems to have greater effect than the stage of dementia itself.

Vestibular schwannomas (VS) have been approached traditionally by middle fossa (MF), translabyrinthine (TL) and retro-sigmoid (RS) approaches. We analyzed the incidence of dural sinus thrombosis associated with trans-labyrinthine approach for VS and analyzed the possible factors associated with the same. Material and methods: All the patients of VS who were operated by the TL approach between January 2012 and April 2014 at Sunnybrook Health Sciences Centre, Toronto were analyzed for the incidence of DST post operatively. The data was collected retrospectively from the electronic patient records and follow up was done clinically and radiologically. Pre-operative MRI and post-operative CT scans (post-operative day 1) were studied in details for detection of DST and for analyzing the preoperative factors which may influence its incidence. Follow-up was assessed by the Glasgow Outcome Score (GOS). Results: A total of 67 patients were operated by the trans-lab approach in the mentioned period. 12 patients were detected to have DST (incidence: 18%). None of the patients were symptomatic for acute or chronic sinus thrombosis. Mean age of presentation was 47 years (range: 20-75 years). Most common presentation was hearing loss (100%) followed by gait ataxia (52%) and dizziness and vertigo (25%). 44 patients (21 males;23 females) were assessed for different possible factors responsible for DST (cystic component/size/T2W hyperintensity/pre-sigmoid space/ tumour anteromedial to internal auditory canal (IAC)/ intra-operative injury to sinuses/dominance of sinuses). None of the above said factors were found to be statistically significant (p<0.05) although certain trends were seen. Overall CSF leak was seen as 6.8% while only 1 patient of DST presented with CSF leak. 11 out of 12 patients were followed up for a period ranging from 2 months-2 years. The mean GOS was grade V where all patients were doing well in the follow up. Conclusions: Dural sinus thrombosis is more common than expected after trans-labyrinthine surgeries for vestibular schwannomas. Majority of these patients with DST are completely asymptomatic (incidental DST) and hence may not need anti-coagulation treatment. This should encourage people in our own country to choose trans-lab approach in skull base surgery without getting too much perturbed (though realistic and careful) about possible venous complications. 8. A Cross Sectional Study on types and triggers of Headache Patients Presenting to a tertiary care Hospital in cuttack. NiharRanjan Biswal1, Ashok kumar Mallick.2 1 DM student, Department of Neurology,S.C.B.Medical College, CUTTACK 2 Professor &Head,Dept. of Neurology,S.C.B. Medical College, CUTTACK.. Abstract Objective A study to describe the classification of types of headache and triggersof migraine in patients who seek medical advice. Materials & Methods Interview of 200 consecutive patients who presented to neurology OPD atS.C.B.Medical college & hospital in cuttackwas conducted. Demographic details, pattern of headache, associated factors and family history were recorded. International Classification of Headache Disorders version 2 was applied. Results 70% of all patients were women and 82% of them were between 20 and 60 years of age. Migraine was the most common disorder (60%) followed by tension-type headache (32.5%), medicationoveruse headache (6.5%) and cluster headache (1%). Chronic daily headache was seen in 48 patients. Eleven percent of female migraineurs suffered from MRM. Study subjects with presence of factors like marriage, family history, inadequate sleep, family stress and exposure to onions had a statistically significant higher proportion than those who did not have such exposure. Conclusions Patients who seek medical advice for headache are usually in their most productive ages. Migraine and tension-type headache are the most common clinical presentations of headache. Onset of migraine is earlier in patients with first-degree family history. Menstrually related migraine affects women with headache episodes of longer duration than other patients and it warrants special therapeutic consideration. 9.. Infantile Cerebral Aspergillosis in an ImmunoCompetent HostA rare case report & review of literature Authors- Prof. Sudhanshu Sekhar Mishra, Dr. Soubhagya Ranjan Tripathy. Abstract - Invasive craniocerebral aspergillosis, often encountered in an immunocompromised setting, is almost uniformly fatal despite radical surgical and medical management, and is frequently a necropsy finding1. Although occurring most commonly in the immunosuppressed patient, cerebral aspergillosis infection has been reported after trauma or neurosurgical procedures 2. Attempts at fungal isolation are often unrewarding and a high index of radiological suspicion is essential3. In the present case, the infant presented with progressive increase in head size (for 2 months since birth) i.e. a head circumference of 55 cm with delayed developmental milestones and intermittent vomiting for 1 month. Histopathological findings were suggestive of invasive aspergillosis, although there was no evidence of the infection in the lungs or paranasal sinuses. Voriconazole therapy was started at 7th post-operative day after the biopsy report. Histologically, aspergillus hyphae were detected in the biopsy material taken during the ETV procedure from the aqueduct. The child has reported back for follow up 4 weeks after discharge, when her head circumference was 47.5 cm; and she was active & feeding well. The first reported case of an aqueductal stenosis caused by an aspergilloma was in 2000 Jan- Feb in Clin Neuropathol. 2000 Jan-Feb;19(1):26-9 (by van Landeghem FK1, et al). Hence our patient may only be the 2nd reported case of hydrocephalus due to aqueductal stenosis caused by Aspergillus. And to the best of our knowledge, this may be the 1st aqueductal stenosis by Aspergillosis in an immunocompetent child, as the earlier case had aplasia cutis congenita at the scalp vertex and hypoplastic left heart syndrome. 10.SPECTRUM OF DEMENTIA IN A RURAL BASED MEDICAL COLLEGE DEPT OF NEUROLOGY,BURDWAN MEDICAL COLLEGE Principal Author: Dr Souvik Dubey Co –Author: Dr Bitoti Chattopadhyay*, Dr A P Bhattacharya*, Dr Mahua Dubey**, Dr H Ahmed*, Dr S P Nandi***, Dr D Laha*****, Dr M K Ghosh*****, Dr S Pal******, Dr A K Mallick*******, Prof S K Das******** *Resident, Dept of Neurology, Burdwan Medical College ** Resident, Dept of Psychiatry, Burdwan Medical College ***RMO-CT, Dept of Neurology, Burdwan Medical College ****Asst. Prof, Dept of Neurology, Burdwan Medical College ***** Associate Professor, Dept of Radiology, Burdwan Medical College ******Professor, Dept of Neurology, Medical College Kolkata *******Professor, Department of Psychiatry, Burdwan Medical College ******** Professor and HOD, Department of Neurology, Burdwan Medical College BACKGROUND:Most of the studies on dementia in India are from urban areas which only constitutes 30% of Indian population,So the idea of this study is to study dementia among rural population from a rural medical college to highlight rural scenario of dementia. OBJECTIVES:Objectives are to diagnose dementia and its various subtypes clinically and radiologically. METHODOLOGY:We evaluated the suspected subjects with possible cognitive dysfunction through history and clinical examination including BMSE(validated Bengali Mental State Examination) as screening tool and KCB(Kolkata cognitive battery),for various domain involvement and EASI(Everyday ability scale for India),for activities of daily living and geriatric depression scale to rule out coexisting depression.Investigation include neuroimaging,Blood and relevant biochemical tests. RESULTS:Among 38 dementia patients,6 reversible(RD),32 irreversible(IRD) and 8 had young onset dementia.Among IRD the frequency was AD(8) ,FTD(3),VaD(12),mixed dementia (4),Parkinson disease with dementia (2) and Parkinsonism plus syndrome in 3(PSP-2;DLB-1).In IRD predominant domain involvement,memory-25,social-24,execuetive-14.5AD had temporal lobe atrophy(B/L).sevenVAD patients had past history of stroke and 10 had typical MRI finding. two FTD had frontal lobe atrophy.onePDD had mid brain atrophy. All mixed dementia had 2 or more vascular risk factor and mixed MRI features.Among RD, probable etiology was (1)hypothyroidism,(1)NPH,(2)tumor,and (2)subdural hematoma. CONCLUSION:In our study, vascular dementia remains top among irreversible dementia. Temporal lobe atrophy in AD and periventricular ischemia in VaD common.Young onset dementia common. Since rural people seek medical consultation late in disease course,social life are most affected.MRI imaging helps in diagnosis. Platform Presentation Comparison of Clinico-radiological Profile of Posterior Circulation Strokes with anterior circulation stroke - Study from a Tertiary Care Centre in Eastern India Bhushan Joshi, Dr. B. K Roy ,Dr D.S. Guin Introduction: Very limited hospital statistics are available for Comparison of Clinicoradiological Profile of Posterior Circulation Strokes with anterior circulation stroke Aims: To evaluate and compare cases of posterior circulation strokes and anterior circulation by analyzing history, conventional risk factors, clinical, laboratory and radiological profile. Material and Methods: 50 cases of posterior circulation strokes and 50 cases of anterior circulation storke visiting Bangur Institute of Neurosciences, IPGMER, Kolkata, from Dec 2013 to September 2014 were evaluated for clinical and laboratory profile and neuroimaging (CT/MRI/DSA). Results : Of the total 50 cases of posterior circulation stroke, 32 (64%) were males (mean age – 48.7yrs) while 18 (36%) were females (mean age – 44.4yrs); 34(68%) were ischemic while 16 (32%) were hemorrhagic. Among ischemic strokes,30% had TIAs (18% had only posterior circulation TIAs). Large artery (hemodynamic) (36%) and embolism (36%) (26%cardiembolism, 10% artery-to-artery embolism) were the most common stroke mechanisms. Distal posterior circulation territory infarcts (44%) were much common than the proximal(26%) or middle territory(30%) infarcts. For hemorrhagic strokes, uncontrolled hypertension was the commonest mechanism while cerebellum and thalamus were the commonest sites. Commonest predisposing factors for ischemic stroke were tobacco addiction followed by hypertension while for hemorrhagic strokes, it was hypertension. Out of 50, 07 died,(14% mortality) 05 of hemorrhagic strokes and 02 of ischemic stroke, commonest causes being septic and metabolic complications Of the total 50 cases of Anterior circulation stroke, 35 (70%) were males (mean age – 49.7yrs) while 15 (30%) were females (mean age – 50.4yrs); 29(58%) were ischemic while 21 (42%) were hemorrhagic. Among ischemic strokes,34% had TIAs. Embolism (60%) (46%cardiembolism, 14% artery-to-artery embolism) was the most common stroke mechanism. For hemorrhagic strokes, uncontrolled hypertension was the commonest mechanism while Basal ganglia were the commonest sites. Commonest predisposing factors for ischemic stroke were tobacco addiction followed by hypertension while for hemorrhagic strokes, it was hypertension. Out of 50, 10 died,(20% mortality) 08 of hemorrhagic strokes and 02 of ischemic stroke, commonest causes being septic and metabolic complications. Conclusion: Clinical profile of posterior and anterior circulation strokes are similar. Embolic stroke mechanism, distal territory location, low GCS and high NIHSS at presentation conveyed the worst prognosis. 2.Title:“Phrenic nerve conduction study in the early stage of Guillain–Barre syndrome as a predictor of respiratory failure” Dr. Barun Kumar Associate Professor Sen, Professor Asit Kumar Senapati, Dr. Alak Pandit, Introduction: Guillain-Barre´ syndrome (GBS) is an acute onset, immune-mediated disorder of the peripheral nervous system. Guillain- Barre Syndrome (GBS) has an unpredictable clinical course with up to 30% of patients requiring assisted ventilation during the course of their illness. In severe cases, a combination of multiple clinical factors culminate in neuromuscular respiratory failure and its main cause is weakness of the diaphragm. Other factors are weakness of intercostal, abdominal, and accessory muscles of respiration, retained airway secretions, atelectasis, and supine posture. Successful management mandates anticipation, prompt recognition and optimal treatment of neuromuscular respiratory failure in GBS. Aims: To evaluate the frequency of phrenic nerve abnormalities in the early Guillain-Barre syndrome and phrenic nerve conduction study as a predictor of respiratory failure in the early stage of Guillain–Barré syndrome. Material and Methods: Fifteen adult patients of GBS above 18 yrs of age admitted to Bangur Institute of Neurosciences, IPGMER, Kolkata, from Jan 2014 to September 2014 and admitted within 14 days of onset, were studied. Clinical and electrodiagnostic data were assesed and compared between those developed respiratory failure and having no respiratory failure. The clinical parameters assessed were median age, gender, antecedent infection, time to peak disability, bifacial weakness, upper limb weakness, bulbar paralysis, neck weakness and autonomic dysfunction. Electrodiagnostic studies included motor nerve conduction and phrenic nerve conduction study (CMAP amplitude, distant latency, duration) done. Multiple logistic regression analysis was used to compare the two groups. Results : Of the total 15 cases of GB syndrome, clinical parameters like median age, gender, antecedent infection, bifacial weakness, upper limb weakness and autonomic dysfunction did not influence the development of neuromuscular respiratory weakness but time to peak disability, bulbar paralysis, neck weakness influenced . Nerve Conduction Study revealed abnormal H reflex and F waves to be the commonest abnormality. Phrenic nerve CMAP latencies, CMAP amplitude, and CMAP duration were significantly different between GBS patients with respiratory failure and without respiratory failure. Two patients with the sum of phrenic nerve latency longer than 18 ms and the sum of bilateral diaphragmatic CMAP amplitude smaller than 0.2 mV and longer CMAP duration required respiratory assistance. Conclusion: Phrenic nerve conduction study (CMAP latency, amplitude and duration) was found to be a sensitive parameter in assessing the severity of the disease and predicting impending respiratory failure in Gb syndrome patient. 3. TranscallosalInterhemispheric Approach for Colloid Cyst: Technical pearls Dr Ashish Kumar Assistant Professor, Department of Neurosurgery, Nizams Institute of Medical Sciences, Hyderabad, Telangana, INDIA Background: Colloid cysts arise from the roof of the third ventricle and are developmental in origin. They commonly obstruct the Foramen of Monroe and result in tri-ventricular hydrocephalus. Headache is most common presenting symptom and timely surgical management is the key.Colliod cysts can be tackled by both open and endoscopic means. Ventricular dilatation remains the key in determining the approach (Trans-callosal Vs Trans-cortical). Surgical disconnection and seizures being the chief drawbacks of trans-callosal and trans-cortical routes respectively. Material & Methods: Four patients were operated in between 2012-1013 at Nizams Institute of Medical Sciences, Hyderabad by single surgeon. 3 patients were operated by trans-callosal and 1 was operated by trans-cortical routes. We describe the approach by demonstrating the key surgical steps by means of operative video and discuss possible complications and its avoidance. Results: All four patients did well. No memory impairment and post-operative hydrocephalus was observed. Intra-operative bleeding occurred in 2 patients which was controlled easily. Conclusions: Interhemispherictrans-callosal approach is a safe and effective corridor for surgical management of III ventricular colloid cysts. Basic understanding of surgical anatomy and adequate expertise may help in achieving excellent outcomes. 4. TITLE : “EVALUATION OF HEADACHE DISORDERS IN PATIENTS OF IDIOPATHIC EPILEPSY” • PRESENTING AUTHOR- UJJAWAL* • QUALIFICATION- MD(GENERAL MEDICINE) • CO-AUTHORS-KUNDU TN**, ROY A*** • PLACE OF WORK-BANGUR INSTITUTE OF NEUROSCIENCES, IPGMER(KOLKATA) *DM Resident, Department of Neurology, Bangur Institute of Neurosciences, IPGMER(KOLKATA) **Professor, Department of Neurology, Bangur Institute of Neurosciences, IPGMER(KOLKATA) ***Assistant Professor, Department of Neurology, Bangur Institute of Neurosciences, IPGMER(KOLKATA) INTRODUCTION : Epilepsy is a condition characterized by recurrent seizures, unprovoked by any immediate identifiable cause. Various types of headache, especially migraine, is considered a relevant co-morbidity in epilepsy. Headache in idiopathic epilepsy may have diagnostic and therapeutic implications. Materials and methods : Herein, we report clinical data on 40 patients of Idiopathic epilepsy. All eligible patients of idiopathic epilepsy were recruited from general OPD or epilepsy clinic of Bangur Institute of Neurosciences. Headache was classified according to ICHD III and headache disability before and after treatment was calculated according to Henry Ford Headache Disability Index(HDI). Results : Out of 40 cases recruited, 23(57.50%) had some or the other type of headache. Maximum number of cases had Idiopathic Generalized Epilepsy(IGE) with Generalized Tonic Clonic Seizures(GTCS) only and most common headache type in these patients being post ictal followed by probable migraine without aura and infrequent episodic Tension type headache. Other types of seizure noted were Juvenile Myoclonic Epilepsy(JME) , Benign Epilepsy with Centro-Temporal Spikes(BECTS) and Juvenile Absence Epilepsy(JAE). Additional drug requirement was high in cases of migraine without aura and in cases of episodic TTH. HDI was reduced to a significant amount in 100% of the cases after additional treatment. Conclusions: This is an ongoing study. Overall, apart from post ictal headache, TTH and migraine was seen in patients of JME and IGE with GTCS only. We noted migraine in one out of 2 patients of BECTS as expected. Patients of JAE did not have any type of headache in the course of the disease. In majority of patients Migraine and TTH required additional therapy, but surprisingly in all of the cased there was significant reduction in the headache frequency and reduction/ improvement in HDI. 5. Visual and surgical outcome in craniopharyngioma Mukund Prasad, Rabindra Kumar, Deepak Karn PARAS HMRI Hospital, Raja Bazar, Bailey Road, Patna-800014 Background: Craniopharyngiomas present with systemic as well as visual symptoms. Treatment strategy varies from subtotal resection(STR) with radiotherapy of residual lesion to gross total resection(GTR). Three consecutive cases of craniopharyngioma treated over last 10 months are presented. Method: Three consecutive cases of craniopharyngioma, first a 17 year old boy with complete loss of vision in both eyes of five days’ duration; second, a 31 year old male with hydrocephalus but no visual symptoms and third, a 32 year old male with temporal field cut in right eye and perception of light only in left eye, were treated surgically with aim of GTR. Results: All were operated via right pterional route with or without additional obitozygomatic or zygomatic osteotomy. Near total resection was achieved in blind seventeen year old boy with return of vision to 6/6 in left eye and 6/24 in right eye and bitemporal field cut after 2 months. Clinical and radiological follow up at six months showed no regrowth or vision deterioration. Thirty one year old male with hydrocephalus had GTR with resolution of hydrocephalus.Clinical and radiological follow up at four months did not reveal any recurrence or new visual deficit. GTR was achieved in third patient also with improvement of field cut in right eye and perception of movement in left eye. Conclusion: Safe GTR of craniopharyngiomas is possible and should be the aim of surgery. 8.Compound Head injuries in adult, An Institutional Experience Ahmed Junaid, Borah Naba, Hussain Zakir , Baishya Kr. Basanta, Ahmed Shameem , Barooah Kr. Rajesh. Department of Neurosurgery, Gauhati Medical College, Assam. Abstract:- compound depressed skull fractures occur when there is a laceration over the fractures, resulting in the internal cranial cavity being in contact with the outside environment. Compound head injuries are associated with a high risk of infection, injury to the underlying brain and post traumatic seizures. Aims and objectives: To analyze the patients with compound head injury, their management protocol and evaluate the incidence of complications and ultimate outcome Materials and methods: 110 consecutive patients with compound head injury admitted under the department of neurosurgery, Gauhati Medical College and Hospital during the period of one year from January 2013 to December 2013 were studied retrospectively. Results And Observations: In our study, majority of patients 57 (51.8%) were found between 16-30 years of age. Male to female ratio was 4.5:1. Mean age was 24.3 years. Most common mode of injury was , other causes included assault, fall from the height etc. Out of total 110 patients, 85 patients (72.27%) were treated surgically and 25 (22.73%) were managed conservatively. Complications occurred in 31 patients (28.18%). Meningitis was the most common complications. Good recovery was observed in 87 cases (79.09%) and 15 cases (13.63%) died.

Digital Poster presentation 1. Comparison of Clinico-radiological Profile of Posterior Circulation Strokes with anterior circulation stroke - Study from a Tertiary Care Centre in Eastern India Bhushan Joshi, Dr. B. K Roy ,Dr D.S. Guin Introduction: Very limited hospital statistics are available for Comparison of Clinicoradiological Profile of Posterior Circulation Strokes with anterior circulation stroke Aims: To evaluate and compare cases of posterior circulation strokes and anterior circulation by analyzing history, conventional risk factors, clinical, laboratory and radiological profile. Material and Methods: 50 cases of posterior circulation strokes and 50 cases of anterior circulation storke visiting Bangur Institute of Neurosciences, IPGMER, Kolkata, from Dec 2013 to September 2014 were evaluated for clinical and laboratory profile and neuroimaging (CT/MRI/DSA). Results : Of the total 50 cases of posterior circulation stroke, 32 (64%) were males (mean age – 48.7yrs) while 18 (36%) were females (mean age – 44.4yrs); 34(68%) were ischemic while 16 (32%) were hemorrhagic. Among ischemic strokes,30% had TIAs (18% had only posterior circulation TIAs). Large artery (hemodynamic) (36%) and embolism (36%) (26%cardiembolism, 10% artery-to-artery embolism) were the most common stroke mechanisms. Distal posterior circulation territory infarcts (44%) were much common than the proximal(26%) or middle territory(30%) infarcts. For hemorrhagic strokes, uncontrolled hypertension was the commonest mechanism while cerebellum and thalamus were the commonest sites. Commonest predisposing factors for ischemic stroke were tobacco addiction followed by hypertension while for hemorrhagic strokes, it was hypertension. Out of 50, 07 died,(14% mortality) 05 of hemorrhagic strokes and 02 of ischemic stroke, commonest causes being septic and metabolic complications Of the total 50 cases of Anterior circulation stroke, 35 (70%) were males (mean age – 49.7yrs) while 15 (30%) were females (mean age – 50.4yrs); 29(58%) were ischemic while 21 (42%) were hemorrhagic. Among ischemic strokes,34% had TIAs. Embolism (60%) (46%cardiembolism, 14% artery-to-artery embolism) was the most common stroke mechanism. For hemorrhagic strokes, uncontrolled hypertension was the commonest mechanism while Basal ganglia were the commonest sites. Commonest predisposing factors for ischemic stroke were tobacco addiction followed by hypertension while for hemorrhagic strokes, it was hypertension. Out of 50, 10 died,(20% mortality) 08 of hemorrhagic strokes and 02 of ischemic stroke, commonest causes being septic and metabolic complications. Conclusion: Clinical profile of posterior and anterior circulation strokes are similar. Embolic stroke mechanism, distal territory location, low GCS and high NIHSS at presentation conveyed the worst prognosis. 2. AN UNUSUAL CASE OF STROKE DUE TO MULTIPLE ISCHEMIC INFARCTION FOLLOWING RUSSELL'S VIPER ENVENOMATION PRESENTING AUTHOR :- Dr LULUP KUMAR SAHOO DM Student Dept. of Neurology CO-AUTHORS-Dr.Ashok Kumar Mallick,Dr.KaliPrasanaSwain,Dr.GeetaMohanty, NiharRanjanBiswal,Dr.Srikant Kumar Sahu Dr PLACE:- S.C.B. MEDICAL COLLEGE ,CUTTACK,ODISHA ABSTRACT BACKGROUND:- Snake bites are common cause of morbidity and mortality in India.Neurological deficit following viper bite is not uncommon and is usually due to intracerebral bleed. Ischemic infarction following viper envenomation has been described by few authors. CASE PRESENTATION:- We report a case of acute ischemic infarction following viper bite in a previously healthy man.36 yr healthy male presented with snake bite over right foot.1hour later he developed local swelling followed by loss of consciousness. During transportation to hospital he had 1 bout of hematemesis. Patient’s attendants noticed decreased movement of right upper & lower limb. He required mechanical ventilation as the Glasgow coma scale was 7/15. Laboratory parameters revealed a normal coagulation profile and no hematuria. Biochemical profile, ECG, X-ray chest and 2D-ECHO were normal. He had no repeat bleeding or seizure.On day of admission 20WBCT was done & blood didn’t clot. On day2,CT scan brain was done which showed multiple infarction involving left Fronto-Temporal lobes,right basal ganglia,thalamus,occipital lobe & left cerebellar parenchyma.He was treated with equine polyvalent ASV( 30 vials), anti-edema measures and anti-platelets. After ASV treatment his 20WBCT became normal. Patient showed good recovery with treatment. CONCLUSION:-Occurrence of ischemic infarction in multiple arterial territories though rare may occur with viper envenomation. 20WBCT—20 min Whole Blood Clot Test 3. AN UNUSUAL CASE OF HIGH DOSE SHORT DURATION OF ASPIRIN INDUCED SPONTANEOUS FRONTAL LOBAR HEAMMORHAGE; A CASE REPORT Author-;DrNihar Ranjan Biswal. DM student Dept. of Neurology ,S.C.B.MEDICAL COLLEGE CUTTACK CO-Authors-Dr.Ashok Kumar Mallick, Dr.KaliPrasanaSwain, Dr.GeetaMohanty,Dr.Lulup Kumar Sahoo, Dr.Srikant Kumar Sahu,Dr.B.Rath,Dr.M.Samanta,Dr.B.K.Mohanty ABSTRACT BACKGROUND; Aspirin has a very high benefit-risk ratio and has been widely used in the secondary prevention of cardiovascular and cerebrovascular diseases.Although sometimes aspirin after taken for long duration associated with gastrointestinal and skin bleeding but it can also cause life threatening intracerebralheammorhage. CASE PRESENTATION; we report a 30 yr male with RHD,severe MR, polyarthritis was on aspirin325mg 4tablets thrice daily for last 2days(6 doses within 48 hours) presented with sudden onset vomiting and altered sensorium with lthemiparesis.Immediate CT scan showed right frontal lobe heammorhage with intraventricularextension.His coagulation profile was within normal range.MRI revealed rt frontal lobe heammorhage with intraventricularextention.MRA was normal.At admission his NIHSS was-8/42 and at discharge his NIHSS was 0/42.BERTHEL index at discharge was 100/100 .He was managed conservatively. Conclusion-spontaneous intracerebralheammorhage should be kept in mind even with short duration of high dose aspirin prescribed for rheumatic arthritis . 4. LINDAU BROTHERS: TWO SIBLINGS WITH HEMANGIOBLASTOMAS Authors- Dr Somnath Prasad Jena, 2nd year MCh student, Prof. (Dr) Sudhansu Sekhar Mishra, Head Of the Department Dept of Neurosurgery, SCB MCH, Cuttack, Odisha INTRODUCTION Hemangioblastomas are benign, slow growing, vascular neoplasms which occur in sporadic and inherited forms. These inherited hemangioblastomas are associated with Von-Hippel Lindau Syndrome(VHL). VHL gene mutations (Chromosome 3p25.3) cause inactivation of the VHL protein resulting in this phenotype. VHL patients must be screened for multiple hemangioblastomas, along with screening for other visceral lesions associated with this condition. We evaluated and operated 2 siblings with Infra-tentorial Hemangioblastomas CASES 1ST BROTHER: The elder brother, a 56year male presented with cerebellar involvement and features of raised ICP 4 years back, with MRI impression Cerebellar Hemangioblastoma. He underwent near-total excision, with histo-pathology confirming Hemangioblastoma. This resulted in resolution of symptoms for 3 years followed by recurrence of symptoms for which he was re-evaluated and re-operated. 2ND BROTHER: The younger brother, a 46 year male, presented with symptoms of foramen magnum compression, on MR imaging revealing multiple cystic lesions in the Posterior fossa, extending through the foramen magnum. He underwent Foramen magnum decompression and excision of the lesion, with histo-pathological proof of hemangioblastoma. Screening of spine and the younger brother revealed a lesion in conus region. FAMILY HISTORY: Mother had renal cell carcinoma DISCUSSION Familial hemangioblastomas are found in VHL syndrome. The complexity of associated conditions like pheochromocytoma adds to the anesthetic challenge and the possibility of a RCC creates diagnostic dilemma of a posterior fossa secondary vs. hemangioblastoma. CONCLUSION Von Hippel Lindau, presenting as infratentorial hemangioblastomas in the siblings is uncommon in routine neuro-surgical practice. These challenges are to be met with clinical know-how and a strict screening protocol in cases encountered. 5. CONGENITAL MALROTATION OF ATLAS WITH UNILATERAL HYPERTROPHY OF ATLANTO-OCIPITAL JOINT – A RARE ANOMALY OF CV JUNCTION AND ITS MANAGEMENT: A CASE REPORT Presenting and corresponding author Pratap Chandra Nath Co-authors- Sudhansu Sekhar Mishra, Rama Chandra Deo, Itibrata Mahanta ABSTRACT Congenital anomalies are commonly encountered in CVJ region due to its unique embryological development. CV junction usually comprises occiput, atlas and axis. However malrotation of atlas in between occiput and Axis with Arnold Chiari Malformation and unilateral lateral mass hypertrophy with atlanto-ocipital joint hypertrophy manifesting features of high cervical myelopathy is hardly reported anomaly. Here we report a case of successfully managed 22 yrs female who presented to us with high cervical compressive myelopathy. Imaging revealed rotation of C1 vertebra around 200 towards left side, with right atlanto-ocipital joint dislocation and hypertrophy of the joint with hypertrophy of right lateral mass of C1, causing Chiari malformation type-1 and right atlanto axial dislocation exposing right C2 superior facet. She underwent right far lateral approach comprising right C1 hemilamiectomy and medialization of right vertebral artery with excision of hypertrophied occipitoatlantal joint extradurally and posteromedial excision of superior articular facet of C1. The patient’s compressive myelopathy features improved post operatively. We report the management of this rare congenital anomaliy with review of litretures related to or like this anomalies. Key Words- Malrotation, Hypertrophy, chiari malformation type-1, compressive myelopathy, Farlateral approach, Hemilaminectomy, posteromedial excision. 6. MULTIPLE SPINAL SCHWANNOMA INTRADURAL- A CASE REPORT BOTH EXTRADURAL AND Presenting Author-Dr Gyani J S Birua Co-Authors- Dr Anil Kumar, Dr C B Sahay, Dr T J Minj, Dr Jeevesh mallik Case Report A 35 yrs old female came to our OPD with complains of inability to stand and walk for 1 month. Her symptoms had started 6 months back and were gradually progressive. She complained of low back pain with radiation to left thigh, of insidious onset which was more prominent in lying down position and on straining. There was associated tingling over both lower limbs. Clinical examination revealed an increased tone and gross sensory diminution in both legs. Motor power was grade 1/5 in both lower limbs in all groups. On further investigation MRI revealed multiple well defined, contrast enhancing dumb-bell lesions at T7-8, T12-L1 and L4-5 level. All the lesions extradural and intradural were completely excised in 2 stages and a good recovery was achieved. Histopathological examination confirmed the lesions to be schwannoma. Discussion Schwannomas are benign, slowly growing, encapsulated peripheral nerve tumours.multiple level schwanomas have been previously reported but existence of both extradural & intradural schwanoma with involvement of cauda equina in a single patient is a rare entity. Keywords – schwanoma, dumb-bell lesions, extra dural , intra dural 7. An interesting neuroimaging case of multiple intracranial SOL. Dr. Mithilesh K. Pandey, Dr. Sunil Baranwal, Associate prof. Kaushik Roy, Prof. Suniti K. Saha, Prof. S. Ghosh Department of Neurosurgery, N R S Medical College and Hospital, Kolkata. Abstract A 58 yrs female was presented in our institution in conscious state with history of headache, vomiting, recurrent generalised seizure, and progressive left sided weakness since 3 months and on examination having anosmia, bilateral temporal hemianopia, left 7th UMN palsy, left spastic hemiparesis. Past history of two episode of generalised seizure 2 years back for which she consulted to local doctor and he advice CT scan brain which was reported normal. 20days before coming to this hospital another CT scan brain done in a medical college and reported two lesion first one suggestive of anterior communicating artery aneurysm and 2nd heterogeneously enhancing lesion in rt. fronto-parietal region. MRI brain was done in our institution showed two lesion an intra-axial heterogenously enhancing lesion in rt. parietal paraventricular region and another strongly enhancing extra-axial lesion in basifrontal region. Patient was operated and biopsy came out for rt. fronto-parietal SOL [Glioblastoma multiforme] and for basifrontal SOL [ Meningothelial menengioma ]. The simultaneous presence of primary brain tumors of different histological type in same patient is very rarely occurs spontaneously. An association with multiple primary intracranial tumors of different histological types not relating to radiotherapy or phacomatosis is a rare event. The incidence of primary brain tumors with different histological types is only 0.3% of all brain tumors. The true incidence of this association may be much higher, because many cases may have a silent clinical course or have been identified but not reported in the literature. 8. Two Cases of Vertical gaze palsy due to same Metabolic etiology Jacky Ganguly There are multiple causes of conjugate vertical gaze impairment like vascular insult to midbrain or thalamus, infective etiologies, multiple sclerosis, neuro-degenerative diseases, metabolic diseases, drugs, etc. Among the metabolic causes, Niemann-Pick type C disease and its variants are one of the most important causes. Niemann-Pick disease type C (NPC) is a rare and fatal neurovisceral lipid storage disorder resulting from autosomal recessively inherited loss-of-function mutations in either Npc1 or Npc2. This disrupts intracellular lipid transport, leading to the accumulation of lipid products in the late endosomes and lysosomes that affects both children and adults. Whereas the disease in children is characterised by mental retardation, seizures and often rapid neurodegeneration, in adults the disease is characterised by slow cognitive decline, major neuropsychiatric illness, development of ataxia, vertical supranuclear opthalmoplegia and dystonia. We have reported cases of two male patients, both presented with dysphagia, spastic dysarthria, vertical gaze palsy (down-gaze more restricted than up-gaze), dystonia without any involvement of higher mental function, muscle power, sensory system and sphincters. One of them had ataxia and the other had parkinsonism too. Bone marrow examination in both the cases had revealed sea blue histiocytes. Vulnerability of cerebellar Purkinje neurons and of neurons in the rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF) to disrupted intracellular lipid storage may explain ataxia and vertical gaze palsy respectively. Considering heterogeneous presentation of NPC, it is often misdiagnosed as other movement or psychiatric disorders and better awareness of this disease is thus required among the clinicians.
