Background: Central nervous system (CNS) involvement is one of the most important extrapulmonary manifestations of tuberculosis (TB) causing considerable mortality and morbidity. Presentations of CNS TB are extremely variable. Treatments are generally more effective if the disease can be detected early. This study is to find out the various clinical patterns and investigation findings that might help in early detection of CNS TB. Objective: This study was conducted to detect various clinical manifestations of adult CNS TB at an earlier stage of evaluation. Methods: This was a hospital based observational study (cross sectional type) conducted on 30 patients of CNS TB who were admitted in Sir Salimullah Medical College Mitford Hospital, Dhaka during a period of 6 months from October 2013 to April 2014 Results: Among the participants 53% were male and 47% were female, with a male female ratio of 1.13: 1. Mean age of the participants was 35.17±6.14 years. Tuberculosis involving brain (i.e. cranial TB) was most common (30.4%) in 15-24 years age group whereas spinal form of TB was most common (42.8%) in 25-34 years age group. Mean age of the participants having Brain TB was 36.46±6.90 years. Mean age of the participants having spinal TB was 32.36±12.52 years. Highest number of the cranial forms of TB was tuberculoma (52.2%) in this study and was found mostly in the young adults. Spinal TB was found in 25-34 years age group in highest number, all but one were Potts disease. Tuberculoma and tuberculous meningitis had an equal distribution in female sex while males had a higher (53.8%) occurrence of tuberculoma. On the other hand, spinal involvement was commoner in male sex (43.5%).Fever was the most common symptom noted in all forms of CNS TB patients (78.26% for brain and 71.43% for spinal cord TB patients) followed by headache and loss of consciousness representing 2nd and 3rd common symptom in brain TB patients. Most common clinical signs in brain TB were signs of meningeal irritation (65.22%), cranial nerve palsies and papillodema while spastic paraparesis with sensory level being the commonest in spinal cases. Tuberculoma was the most frequent neuro-radiologic findinds in case of brain TB patients and paraspinal soft tissue shadow with vertebral collapse was commoner in spinal TB patients. Conclusion: This study has highlighted the relative frequency of various types of brain and spinal TB lesions along with the symptoms, signs and laboratory findings in Bangladeshi adult patients. In Bangladesh, tuberculosis should be always an important differential diagnosis in patients of fever with headache as well as spastic paraplegia or quadriplegia for any duration in any sex group.

Background: Epidemiologic studies have identified hyper-homocysteinemia as a possible risk factor for atherosclerosis. The aim of my study was based on evaluation of relationship between homocysteinemia with carotid artery stenosis in ischemic stroke patients.Methods and materials: It was a prospective observational study conducted in the Department of Neurology, Sir Salimullah Medical College & Mitford hospital, Dhaka. Thirty six consecutive patients with ischemic stroke were analyzed by serum total homocysteine, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride and extracranial Doppler ultrasonography and vascular risk factors were recorded. Equal number of controls of same ages were compared with the case group.Result: Mean fasting blood sugar, serum fasting total cholesterol (TC), serum fasting Low density lipoprotein (LDL) were significantly higher in case group (p=0.001). Serum TC and LDL had a positive correlation with serum homocystine (p=0.001). Serum High density lipoprotein (HDL) had a negative correlation (p=0.718) and serum triglyceride (TG) had a negative correlation (p = 0.182). Total plasma fasting homocysteine level in case group was 21.89 ± 9.38 ìmol/l and control group was 12.31 ± 3.27 ìmol/l, (p=0.001). Elevated fasting homocysteine level was found in 75.0% of the ischemic stroke patients and in 16.67% of healthy controls (p=0.001).On the basis of clinical evaluation and results of imaging studies, etiological classification of the ischemic stroke patients were made, where 36.1% cases were small artery disease, 38.9% large artery disease, 8.3% cases cardioembolic and in 16.7 % other causes. Among the cases, carotid duplex study was found normal in seven cases (19.4%), Group 1 findings in seven cases (19.4%), group 2 findings in eight cases (22.2%), group 3 findings in thirteen cases (36.1%) and group 4 findings in one case (2.8%). All abnormal carotid duplex findings were significantly higher among cases with elevated level of homocysteine (p=0.001, 0.001, 0.001).Conclusion: The incidence of hyperhomo-cysteinemia is higher in ischaemic stroke cases than that in age-sex matched healthy controls. Hyperhomocysteinemia in ischaemic stroke patients has been determined as vascular risk factor in our study. Significant correlation has been found between homocysteine concentration and intraluminal thickness and carotid artery stenosis.Bangladesh Journal of Neuroscience 2012; Vol. 28 (1): 1-9

Background: Parkinson’s disease dementia (PDD) is a common consequence during the course of the disease. It deeply influences patients’ prognosis, quality of life, caregiver burden and economic strain. However, effective treatment for PDD is currently unclear. Clinical and demographic predictors for this comorbidity are not well studied. Objectives: To investigate putative risk factors for the development of dementia in patients with Parkinson’s disease (PD) attending a tertiary care and teaching hospital in Bangladesh. Methods: One hundred thirty-one consecutive PD cases were enrolled in this cross-sectional study; whose disease duration was more than a year. Comparison was done between demented and non-demented PD cases. Structural CNS diseases including secondary parkinsonism were excluded by clinically and MRI of brain for all cases. Dementia was evaluated based by DSM-IV and assessed using mini-mental state examination (MMSE) score and Parkinson’s disease dementia short screen (PDD-SS) score. Severity of disease was evaluated by Hoehn and Yahr stage (H-Y I to V). Depression was assessed using DSM-IV. Data were analysed on a logistic regression model using SPSS v 23. Results: The overall frequency of dementia was 38%. The mean (SD) age of the demented and non-demented PD cases was 73.32(8.86) and 63.98 (6.19) years respectively. On multivariate logistic regression model, age ³70 years [OR=4.25, p=0.031], diabetes [OR=5.37, p=0.019], hypertension [OR=7.63, p=0.011], disease duration ³5 years [OR=10.01, p<0.001], H-Y stage e” 3 [OR= 9.52, p<0.001] and depression [OR=8.79, p<0.001] were significantly associated with PDD. Conclusion: In this study of PD cases, overall risks of dementia were advancing age, diabetes, hypertension, longer disease duration, higher disease stage and presence of depressive illness.

Background: Epidemiologic studies have reported that microalbuminuria is a risk factor for stroke in men and a limited case control study found that the highest quintile of microalbuminuria values was associated with 13 fold increased risk for stroke. The goal of this study is designed to determine its relationship to risk factors for ischemic stroke. Materials and Methods: It was a prospective observational study conducted in the Department of Neurology, Sir Salimullah Medical College Mitford Hospital, Dhaka, Bangladesh. Fifty consecutive patients with ischemic stroke with at least two risk factors who fulfilled the inclusion criteria of case were confirmed by CT or MRI. Equal number of controls same ages without stroke who had at least two risk factors were compared with the case group. The patients were assessed clinically with structured questionnaire including blood pressure, height and weight, and monitoring blood glucose and microalbuminuria. Results: Microalbuminuria was found 58.0% in patients with ischemic stroke. Patients who had diabetes mellitus will have 13.86 times the risk for developing microalbuminuria (p<0.05). Patients who had HTN will have 4.19 times the risk for developing microalbuminuria (p<0.05) and BMI (³23 kg/m 2 ) will have 4.24 times the risk for developing microalbuminuria with (p<0.05). Whereas TIA, IHD, dyslipidemia, smoking and positive family history were not significantly (P>0.05) associated with microalbuminuria in patients with ischemic stroke. Conclusion: The findings of this study show that diabetes is the factor most closely associated with microalbuminuria followed by HTN and BMI³23 kg/m 2 with statistically significance in patients with ischemic stroke.

Background: Several epidemiological studies have identified the association of abnormal ABPI with ischemic stroke. So the goal of this study was to determine the actual relationship of ABPI with ischemic stroke in the context of our country. Materials and Methods: This case control study was carried out in the Department of Neurology, Sir Salimullah Medical College and Mitford Hospital, Dhaka, Bangladesh. ABPI was measured by Doppler ultrasound machine of 100 patients who were admitted to the Mitford Hospital during the study period. Among them 50 patients with Ischemic stroke, confirmed by CT/MRI scan of brain were considered as ‘case’ and 50 age- sex matched individuals with one or more vascular risk factors (VRF) but without stroke were considered as ‘control’. Then the results of ABPI were compared between the two groups. Results: Among the 50 patients with ischemic stroke (case group) , 74% had normal ABPI and 26% had ABPI< 0.9; on the other hand among 50 age and sex matched individuals (control group) 90% had normal ABPI and 10% had ABPI <0.9. The difference was statistically significant between two groups (p=<0.05).This association remained significant even after adjustment for potential confounders (age, gender, high BMI, hypertension, diabetes mellitus, hyperlipidemia, smoking, ischemic heart disease and family history) in a multiple logistic regression model. Conclusion: The incidence of low ABPI is significantly higher in ischemic stroke patients than the age- sex matched control. Bangladesh Journal of Neuroscience 2013; Vol. 29 (1) : 31-42
