Stroke In Pakistan, Bhojo A Khealani, Bilal Hameed, Uzma U Mapari

Section of Neurology

Stroke is the most common cause of disability and a leading cause of mortality world wide. Though the incidence is falling in West but probably is rising in Asia. The burden of stroke risk factors in Pakistan is enormous e.g. by 2020 Pakistan will be 4th most populous country in terms of diabetic patients. Similarly every 3rd person above age of 45 years has hypertension. Ironically a great majority of these patients are unaware of their diagnosis. This is further complicated by the fact that most of diagnosed patients have uncontrolled hypertension, as a result of poor compliance on patients …

Perinatal Arterial Ischaemic Stroke: An Update With Literature Review, S. H. Ibrahim, Zafar Abdul Mueed

Department of Paediatrics and Child Health

Perinatal arterial ischaemic strokes are a major cause of morbidity in the neonatal period and leads to significant neurological morbidity. It is however under recognized as an entity and usually missed till the baby is 3-4 months of age when they first present with hemiplegia. Perinatal arterial ischaemic strokes are not reported from our country and this may be due to the fact that neurodiagnostic modalities were not available until the last few years. Even now this is not available in the smaller cities of our country. In this review we will discuss the common issues related to etiology and …

Estrogen Replacement Therapy Induces Functional Asymmetry On An Odor Memory/Discrimination Test, Richard L. Doty, Mehreen Kisat, Isabelle Tourbier

Section of Otolaryngology, Head & Neck Surgery

The secondary afferents of the olfactory system largely project to the ipsilateral cortex without synapsing in the thalamus, making unilateral olfactory testing a useful probe of ipsilateral hemispheric activity. In light of evidence that lateralized performance on some perceptual tasks may be influenced by estrogen, we assessed left:right nostril differences in two measures of olfactory function in 14 post-menopausal women receiving estrogen replacement therapy (ERT) and 48 post-menopausal women receiving no such therapy. Relative to women not taking ERT, those receiving ERT exhibited better performance in the left nostril and poorer performance in the right nostril on an odor memory/discrimination …
