Heparin In The Treatment Of Cerebral Venous Thrombosis., Saad Shafqat, Ayeesha Kamran Kamal, Mohammad Wasay

Department of Medicine

Cerebral venous thrombosis (CVT) is a potentially life-threatening condition requiring rapid diagnosis and urgent treatment. Heparin anticoagulation is the time-honoured treatment, and is advocated in all cases of CVT, irrespective of etiology or presence of haemorrhage. The supportive evidence is largely observational; data from randomized placebo-controlled trials shows a nonsignificant trend favouring heparin. Current practice is to begin heparin (unfractionated or low-molecular weight) immediately on confirmation of the diagnosis. Newer antithrombotic agents such as ximelagatran may offer advantages over heparin and need to be investigated in the treatment of CVT.

Cerebral Venous System Anatomy, Muhammad Azeem Uddin, Tanveer Ul Haq, Muhammad Zafar Rafique

Department of Radiology

Cerebral venous system can be divided into a superficial and a deep system. The. superficial system comprises of sagittal sinuses and cortical veins and these drain superficial surfaces of both cerebral hemispheres. The deep system comprises of lateral sinus, straight sinus and sigmoid sinus along with draining deeper cortical veins. Both these systems mostly drain themselves into internal jugular veins. The veins draining the brain do not follow the same course as the arteries that supply it. Generally, venous blood drains to the nearest venous sinus, except in the case of that draining from the deepest structures, which drain to …

Computed Tomographic Imaging Of Cerebral Venous Thrombosis, Mohammad Kamran Kamal

Department of Radiology

Cerebral venous thrombosis (CVT) is an entity which is not rare and can have devastating consequences if not diagnosed and treated in a timely manner. Although, the gold standard for diagnosing this entity is a catheter angiogram, magnetic resonance venography, by virtue of its non-invasiveness and detailed demonstration of the cerebral venous structures, has become the diagnostic modality of choice for this entity. However, in a resource-strapped country like Pakistan, CT scan remains the primary first (and sometimes the only) diagnostic modality used in patients with neurological problems. Therefore, it is important to recognize the signs of cerebral venous thrombosis …

Pathophysiology Of Cerebral Venous Thrombosis--An Overview., Ahmed Itrat, Sana Shoukat, Ayeesha Kamran Kamal

Department of Medicine

Cerebral venous sinus thrombosis is a disorder with a unique pathophysiology which needs to be described. A Medline search of all articles detailing pathophysiology of CVST was done, using keywords: cerebral venous thrombosis and pathophysiology. In addition, major texts were reviewed for additional references. The pathophysiology of CVST depends on two interconnected events, local signs due to venous infarct, e.g., hemiparesis and global signs due to raised ICP from an obstructed venous system--papilloedema and isolated intracranial hypertension being one of them. Pathophysiology of CVST is diverse and makes it easier to understand the diversity of clinical presentations.

Local Thrombolytic Treatment Of Cerebral Venous Thrombosis In Three Paediatric Patients, Mohammad Wasay, Rohit Bakshi, Alper Dai, Steve Roach

Section of Neurology

There is increasing evidence that local thrombolysis can be used with relative safety and efficacy in adults with superior sagittal sinus thrombosis (SSST). However, little data is available on the use of local thrombolysis in children with SSST. We report three patients who received local thrombolysis for dural sinus thrombosis. Two patients received urokinase and one patient received urokinase followed by local TPA infusion. Recanalization was achieved in two patients.

Treatment Of Spinal Tuberculosis: Role Of Surgical Intervention, Ather Enam, Ahmed Ali Shah

Section of Neurosurgery

The treatment of tuberculosis of the spine (Pott's disease) is essentially conservative and a vast majority of patients can be successfully managed on antituberculo us therapy (ATT) alone.1 Surgery is indicated in a few specific cases where deformity of spine, pain, or neurological compromise is becoming a serious issue. In cases where surgery is indicated the benefits are almost immediate and excellent. Tuberculosis (TB) is one of the leading causes of infectious disease-related deaths in under-developed countries and it has had a resurgence in developed countries as well. The most common site of bony dissemination of this disease is in …

Botulinum Toxin Type-A In The Management Of Cerebral Palsy: Low Or High Dose?, Alper I. Dai, Mohammad Wasay

Department of Medicine

Cerebral palsy is the most common cause of severe physical disability in childhood. Spasticity is a common and disabling symptom for many patients with cerebral palsy. Therapy for spasticity is symptomatic with the aim of increasing functional capacity and relieving discomfort. Spasticity treatment by orally administered drugs and intramuscular chemodenervation agents has become more frequent. Most oral medications to treat spasticity have been inadequately studied in children, especially those with cerebral palsy. Since its first use in pediatric patients, reported in 1993, botulinum toxin (BTX-A), a relatively recent addition to the available medical interventions for children with cerebral palsy, has …

Section of Otolaryngology, Head & Neck Surgery

We conducted a study to evaluate the use of a pediatric rigid otoendoscope for determining the extent of middle ear disease and for assessing ossicular integrity and mobility during tympanoplasty. Our study population was made up of 132 patients who were undergoing surgery for the treatment of chronic suppurative otitis media; of this group, 41 patients underwent otoendoscopy and 91 underwent scutum lowering for purposes of visualization. In the otoendoscopy group, the ossicles were successfully visualized and their mobility assessed in 34 patients; the remaining 7 patients subsequently underwent scutum lowering. A 30° endoscope allowed for complete visualization of the …

Section of Pulmonary & Critical Care

A review was made of the records of all patients with pulmonary tuberculosis and diabetes mellitus admitted over a 5-year period to a teaching hospital in Karachi, Pakistan. Among 42358 patients, the total number with both tuberculosis and diabetes was 173. The prevalence of tuberculosis in diabetic patients was 10-times higher than in non-diabetic patients and prevalence increased with duration of diabetes. The lower lung field was most frequently involved, followed by the upper and middle. Bilateral involvement was seen in half and an associated pleural effusion in one-third of the patients. Cavitating lesions were seen in 32% of men …

Community Health Sciences

Aspects of the social environment, including social conditions (socio-economic status, household situations, chronic illnesses) and social relations (attitude and behaviors of relations) are major determinants of depression among women. This study evaluates the relative power of social relations and social conditions in predicting depression among pregnant women in Pakistan. In the qualitative phase of the study, social environmental determinants were identified through literature search, and experts' opinions from psychologists, psychiatrists, gynecologists, sociologists and researchers. Along with this, 79 in-depth interviews were conducted with pregnant women drawn from six hospitals (public and private) and two communities in Karachi, Pakistan. Identified determinants …
