Obstetric cerebral venous thrombosis

Pregnancy and puerperium are most prevalent prothrombotic states leading to cerebral venous thrombosis. Likelihood of stroke to be of venous origin is greater in stroke associated with pregnancy compared to stroke unrelated to pregnancy. Pregnancy induces several changes in coagulation system, which persists at least during early puerperium, rendering it a prothrombotic state. Hypercoaguability worsens further after delivery as a result of volume depletion and trauma. During puerperium additional risk factors include infection and instrumental delivery or Caesarean section. The management follows general rules as for the venous thrombosis unrelated to pregnancy, however the prognosis is different

Predictors pf ischemic versus hemorrhagic strokes in hypertensive patients

To identify the factors that predispose to ischemic versus hemorrhagic stroke in hypertensive patients. Cohort study. The study was conducted at the Aga Khan University Hospital [AKUH], Karachi, from August 1999 to May 2001. All the hypertensive patients, who were registered in AKUH acute stroke outcome data base, over a period of 22 months, were identified and from this cohort the patients with first ever stroke were selected. The data regarding demographics, stroke type [ischemic vs. hemorrhagic], pre-existing medical problems, laboratory and radiological investigations was recorded and analyzed. Five hundred and nineteen patients with either ischemic stroke or parenchymal hemorrhage were registered over a period of 22 months. Three hundred and forty-eight patients [67%] had hypertension and of these, 250 had first ever stroke at the time of admission. Presence of diabetes mellitus [OR: 3.76; CI: 1.67-8.46] and ischemic heart disease [OR: 6.97; CI: 1.57-30.98] were found to be independent predictors of ischemic strokes. Presence of diabetes mellitus and ischemic heart disease predict ischemic stroke in a patient with hypertension

Kleine Levin syndrome

Kleine-Levin Syndrome [KLS] is a rare disorder of uncertain etiology, characterized by recurring episodes of undue sleepiness lasting for days. We report a case of young female presenting with episodes of undue sleep along with hypersexuality and excessive food intake, who improved significantly on lithium and valproate. KLS should be considered in young patients, who present with episodes of undue somnolence
