Jacobsen syndrome is a rare chromosomal disorder caused by distal deletions in the long arm of chromosome 11. All patients with Jacobsen syndrome have Paris-Trousseau syndrome, a bleeding disorder that causes neonatal thrombocytopenia, and persistent platelet dysfunction. Despite that, to date there are no reported cases of hemorrhagic strokes occurring in patients with Jacobsen syndrome. In the last 6 years at least six cases of brain hemorrhages in patients with Jacobsen syndrome have occurred. In this report, we perform a retrospective review of these six cases...

Except when contraindicated, anticoagulation should be initiated when pulmonary embolism (PE) is strongly suspected and the bleeding risk is perceived to be low, even if the evaluation has not been completed. Low-risk patients with acute PE are simply continued on anticoagulation. Severely ill patients with high-risk (massive) PE require aggressive therapy, and if the bleeding risk is acceptable, systemic thrombolysis should be considered. However, despite clear evidence that parenteral thrombolytic therapy leads to more rapid clot resolution than anticoagulation alone, the risk of major bleeding including intracranial bleeding is significantly higher with thrombolytic therapy...

A 34-year-old woman was admitted to hospital after sustaining a head injury in a motor vehicle accident (day 1). No signs of neurological deficit, skull fracture, brain contusion, or intracranial bleeding were evident. She was discharged without symptoms on day 4. However, headache and nausea worsened on day 8, at which time serum sodium level was noted to be 121 mEq/L. Treatment with sodium chloride was initiated, but serum sodium decreased to 116 mEq/L on day 9. Body weight decreased in proportion to the decrease in serum sodium...

AIM: The neuropeptide calcitonin gene-related peptide (CGRP) is found in afferent sensory nerve fibers innervating the resistance arteries and plays a pivotal role in a number of neurovascular diseases such as migraine and subarachnoid bleedings. The present study investigates the binding and antagonistic characteristics of small non-peptide CGRP receptor antagonists (i.e. gepants) in isolated rat brain and mesenteric resistance arteries. METHODS: The antagonistic behavior of gepants was investigated in isolated rat mesenteric arteries using a wire myograph setup while binding of gepants to CGRP receptors was investigated in rat brain membranes using a radioligand competitive binding assay...

Coagulopathy is common in intensive care units (ICUs). Many physiologic derangements lead to dysfunctional hemostasis; these may be either congenital or acquired. The most devastating outcome of coagulopathy in the critically ill is major bleeding, defined by transfusion requirement, hemodynamic instability, or intracranial hemorrhage. ICU coagulopathy often poses complex management dilemmas, as bleeding risk must be tempered with thrombotic potential. Coagulopathy associated with intracranial hemorrhage bears directly on prognosis and outcome...

BACKGROUND: Cerebral amyloid angiopathy (CAA) is a degenerative vasculopathy that is classically associated with lobar intracerebral or sulcal hemorrhage. Its prevalence is estimated at 30% in the seventh decade and 50% in the eighth and ninth decades. In this review, we summarize the risks linked to CAA with respect to the treatment and prevention of stroke. METHODS: This review is based on pertinent publications retrieved by a selective search employing the terms "amyloid cerebral angiopathy," "stroke," "intra - cerebral bleeding," and "acute stroke therapy...

OBJECTIVES: A brain electrical activity biomarker for identifying traumatic brain injury (TBI) in Emergency Department (ED) patients presenting with high GCS after sustaining a head injury has shown promise for objective, rapid, triage. The main objective of this study was to prospectively evaluate the efficacy of an automated classification algorithm to determine the likelihood of being CT positive, in high functioning TBI patients in the acute state. METHODS: Adult patients admitted to the ED for evaluation within 72 hours of sustaining a closed head injury with GCS 12-15were candidates for study...

Leukoencephalopathy with brain calcifications and cysts (LCC) is neuroradiologically characterized by leukoencephalopathy, intracranial calcification, and cysts. Coats plus syndrome is also characterized by the same neuroradiological findings together with defects in retinal vascular development. Indeed, LCC and Coats plus were originally considered the same clinical entity that was termed cerebroretinal microangiopathy with calcifications and cysts, but evidence now suggests that they are genetically distinct...

PURPOSE: To provide evidence-based guidelines for early enteral nutrition (EEN) during critical illness. METHODS: We aimed to compare EEN vs. early parenteral nutrition (PN) and vs. delayed EN. We defined "early" EN as EN started within 48 h independent of type or amount. We listed, a priori, conditions in which EN is often delayed, and performed systematic reviews in 24 such subtopics. If sufficient evidence was available, we performed meta-analyses; if not, we qualitatively summarized the evidence and based our recommendations on expert opinion...

Hematological abnormalities including thrombocytopenia are common in patients living with HIV infection. Patients with HIV infection related thrombocytopenia present generally with only minor bleeding problems. But cases of subdural hematoma are very rare. A 61-year-old female with a history of HIV infection of 9 years' duration presented with a 3-month history of generalized headache associated with visual blurring and anterograde amnesia. There was no history of trauma or fever. She was treated empirically for cerebral toxoplasmosis for 6 weeks without any improvement of the symptoms...

Thrombosis and stroke are major causes of disability and death worldwide. However, the regular antithrombotic drugs may have unsatisfactory results and side effects. Platonin, a cyanine photosensitizing dye, has been used to treat trauma, ulcers and some acute inflammation. Here, we explored the neuroprotective effects of platonin against middle cerebral artery occlusion (MCAO)-induced ischemic stroke in mice. Platonin(200 μg/kg) substantially reduced cerebral infarct volume, brain edema, neuronal cell death and neurological deficit scores, and improved the MCAO-reduced locomotor activity and rotarod performance...

In light of the recent terrorist attacks in Europe, we need to reconsider the organization of rescue and medical management and plan for an attack involving multiple pediatric victims. To ensure quick surgical management, but also to minimize risk for on-site teams (direct threats from secondary terrorist attacks targeting deployed emergency services), it is crucial to evacuate patients in a swift but orderly fashion. Children are vulnerable targets in terrorist attacks. Their anatomical and physiological characteristics make it likely that pediatric victims will suffer more brain injuries and require more, often advanced, airway management...

: 98 Background: VTE represents a significant risk for morbidity and mortality in cancer patients. Hospitalized solid tumor patients at PM are especially at risk (15% of inpatients experienced a VTE event in 2004 when prophylaxis rate was 19%). Institution-wide VTE prophylaxis policy was implemented, and prophylaxis uptake reached nearly 97% in Sept 2012. We are interested in whether the prophylaxis policy made any impact in reducing VTE incidences over time. Our objective is to compare inpatient VTE frequency before and after the implementation of the VTE prophylaxis policy (IPP) in Sept 2012 at PM...

Infants born before 29 weeks gestation incur a major risk of preterm encephalopathy and subependymal/intracerebral/intraventricular haemorrhage. In mice, an ontogenic window of haemorrhage risk was recorded up to 5 days after birth in serpine1 knock-out animals. Using proteome and transcriptome approaches in mouse forebrain microvessels, we previously described the remodelling of extracellular matrix and integrins likely strengthening the vascular wall between postnatal day 5 (P5) and P10. Haemorrhage is the ultimate outcome of vessel damage (i...

AIMS: Catheter ablation is the most efficacious rhythm control therapy in atrial fibrillation (AF) patients. There is growing evidence that catheter ablation procedures are best performed during continuous oral anticoagulation, but outcomes are variable depending on the anticoagulation strategy or agent chosen. Specifically, there is a need to evaluate the peri-procedural use of non-vitamin K antagonist oral anticoagulants (NOACs) in patients undergoing catheter ablation of AF. The AXAFA-AFNET 5 trial will test whether peri-procedural anticoagulation therapy using apixaban is a safe alternative to vitamin K antagonist (VKA) therapy for patients undergoing catheter ablation of AF...

Intraventricularhemorrhage (IVH) is one of thecommon morbidities among preterm neonates. In thepresentstudy, we set out to evaluate the efficacy of two prophylactic modalities (ibuprofen and indomethacin prophylaxis) for prevention of IVH in our local setting. A prospective study was carried out in Akbar-Abadi Hospital, Tehran-Iran (2013-2014). Ninety-six preterm neonates who cared in closed incubator entered the study. Neonates randomly assigned into 3 groups; control, oral indomethacin (0.2 mg/kg indomethacin daily for 3 days) and oral ibuprofen (10,5,5 mg/kg ibuprofen every 24 hours during 3) administration...

BACKGROUND: Tracheostomy is considered the airway management of choice for patients who need prolonged mechanical ventilation support. Percutaneous Dilatational Tracheotomy (PDT) is a technique that can be performed easily and rapidly at bedside and is particularly useful in the intensive care setting. The Griggs percutaneous tracheotomy is unique in its utilization of a guide wire dilator forceps. OBJECTIVE: We aimed to describe the early perioperative and late postoperative complications of PDT using the Griggs technique in patients in the intensive care unit (ICU)...
