Fuzzy Logic In Neurosurgery: Predicting Poor Outcomes After Lumbar Disk Surgery In 501 Consecutive Patients, Muhammad Shahzad Shamim, Ather Enam, Uvais Qidwai
Section of Neurosurgery
Background: Despite a lot of research into Patient selection, a significant number of Patients fail to benefit from surgery for symptomatic lumbar disk herniation. We have used Fuzzy Logic-based fuzzy inference system (FIS) for identifying Patients unlikely to improve after disk surgery and explored FIS as a tool for surgical outcome prediction.
Methods: Data of 501 Patients were retrospectively reviewed for 54 independent variables. Sixteen variables were short-listed based on heuristics and were further classified into memberships with degrees of membership within each. A set of 11 rules was formed, and the rule base used individual membership degrees and their …

Section of Neurology
Background: The burden of cerebrovascular disease in developing countries is rising sharply. The prevalence of established risk factors of stroke is exceptionally high in Pakistan. However, there is limited data on the burden of stroke and transient ischemic attack (TIA) in South Asia. We report the first such study conducted in an urban slum of Karachi, Pakistan. Methods:Individuals 35 years of age or older were invited for participation in this investigation through simple random sampling. A structured face-to-face interview was conducted using a pretested stroke symptom questionnaire in each participant to screen for past stroke or TIA followed by …

Cost-Effectiveness Of Clipping Vs Coiling Of Intracranial Aneurysms After Subarachnoid Hemorrhage In A Developing Country-A Prospective Study, Muhammad Zubair Tahir, Ather Enam, Rushna Pervez Ali, Atta Bhatti, Tanveer Ul Haq
Section of Neurosurgery
Background: Endovascular coil treatment is being used increasingly as an alternative to clipping for some ruptured intracranial aneurysms. The relative benefits of these 2 approaches have yet to be fully established. The aim of this study was to compare the clinical outcome, resource consumption, and cost-effectiveness of endovascular. treatment vs surgical clipping in a developing country.
Methods: The study population consisted of 55 Patients with aneurysmal subarachnoid hemorrhage (SAH) identified prospectively from January 2004 to June 2007. Of the 55 Patients with ruptured intracranial aneurysms, 31 underwent surgical clipping, whereas 24 were treated via interventional coils. Clinical outcome at 6 …

Section of Neurosurgery
A 14-year-old male presented to the neurosurgical clinic with swelling just above the right eye which had been growing slowly for the last eight years. The swelling first appeared following a non-penetrating trauma eight years ago. On examination it was a non-tender, non-erythematous, firm, round swelling causing marked proptosis and diplopia on downward gaze only. The visual acuity was intact. MRI showed an intraorbital, extraconal mass isointense on T1 and hypointense on T2 imaging. A diagnosis of orbital tumor was made. A white, friable mass consistent with meningioma was resected. However histopathology report later showed it to be an Aspergilloma. …

Relating Visual To Verbal Semantic Knowledge: The Evaluation Of Object Recognition In Prosopagnosia, Jason J. S. Barton, Hashim-M Hanif, Sohi Ashraf
Section of Neurology
Assessment of face specificity in prosopagnosia is hampered by difficulty in gauging pre-morbid expertise for non-face object categories, for which humans vary widely in interest and experience. In this study, we examined the correlation between visual and verbal semantic knowledge for cars to determine if visual recognition accuracy could be predicted from verbal semantic scores. We had 33 healthy subjects and six prosopagnosic Patients first rated their own knowledge of cars. They were then given a test of verbal semantic knowledge that presented them with the names of car models, to which they were to match the manufacturer. Lastly, they …

Background: Intracranial stenosis is the most common cause of stroke among Asians. It has a poor prognosis with a high rate of recurrence. No effective medical or surgical treatment modality has been developed for the treatment of stroke due to intracranial stenosis. We aim to identify risk factors and biomarkers for intracranial stenosis and to develop techniques such as use of transcranial doppler to help diagnose intracranial stenosis in a cost-effective manner.
Methods/Design: The Karachi Intracranial Stenosis Study (KISS) is a prospective, observational, case-control study to describe the clinical features and determine the risk factors of patients with stroke due …

Classification And Clinical Features Of Headache Disorders In Pakistan: A Retrospective Review Of Clinical Data, Muhammed Murtaza, Mehreen Kisat, Haroon Daniel, Aziz Sonawalla
Department of Medicine
Background: Morbidity associated with primary headache disorders is a major public health problem with an overall prevalence of 46%. Tension-type headache and migraine are the two most prevalent causes. However, headache has not been sufficiently studied as a cause of morbidity in the developing world. Literature on prevalence and classification of these disorders in South Asia is scarce. The aim of this study is to describe the classification and clinical features of headache patients who seek medical advice in Pakistan.
Methods and Results: Medical records of 255 consecutive patients who presented to a headache clinic at a tertiary care hospital …

Objective: To study the association between admission hyperglycaemia and the presence and pattern of intracranial and extracranial vascular disease.
Methods: This retrospective study was conducted at a major tertiary care hospital in Karachi, Pakistan. Patients who had presented with acute stroke and had undergone a carotid ultrasound doppler of the carotids and/or Magnetic Resonance Angiography (MRA) of the brain were included in the study. A multiple logistic regression analysis of variables was done for an abnormal finding on each investigation.
Results: Out of the total of 216 patients, the age of majority of the patients (83.3%) was >50 years …

The burden of coronary heart disease (CHD) is increasing at a greater rate in South Asia than in any other region globally, but there is little direct evidence about its determinants. The Pakistan Risk of Myocardial Infarction Study (PROMIS) is an epidemiological resource to enable reliable study of genetic, lifestyle and other determinants of CHD in South Asia. By March 2009, PROMIS had recruited over 5,000 cases of first-ever confirmed acute myocardial infarction (MI) and over 5,000 matched controls aged 30-80 years. For each participant, information has been recorded on demographic factors, lifestyle, medical and family history, anthropometry, and a …

Asian Cerebral Venous Thrombosis Registry: Study Protocolv, Mohammad Wasay, Ayeesha Kamal, Bhojo Khealani
Department of Medicine
Introduction:
Cerebral venous thrombosis (CVT) is a well known but poorly reported entity. Most of the studies and registries related to CVT are reported from European countries. No large multi-center or multi- national data base or registry has been reported from Asian countries. CVT is not uncommon in Asia especially in south Asian subcontinent including India, Pakistan and Bangladesh. One study reported from India that CVT accounted for half of all strokes in the young and 40% of strokes in women. Review of CVT cases from Asian countries is suggestive of differences in risk factors profile and outcome in these …

Background: Moyamoya is a rare cerebrovascular disease of unknown etiology. The data on moyamoya disease from Pakistan is sparse. We report a case series of 13 patients who presented with moyamoya disease to a tertiary care hospital in Pakistan with a national referral base.
Methods: We conducted a retrospective review of thirteen patients who presented to The Aga Khan University and diagnosed with "Moyamoya Disease" during the period 1988 – 2006. These patients were identified from existing hospital database via ICD-9 codes. A predesigned questionnaire containing information about clinical presentation, management and neuroimaging was administered to all identified patients. Results: …
