Data on paediatric pulmonary embolism (PE) are scarce. We sought to systematically review the current literature on childhood PE and conducted a search on paediatric PE via PubMed (1946-2013) and Embase (1980-2013). There was significant heterogeneity in reported data. Two patterns were noted: classic thromboembolic PE (TE-PE) and in situ pulmonary artery thrombosis (ISPAT). Mean age of presentation for TE-PE was 14.86 years, and 51 % of cases were males. The commonest method for diagnosis of TE-PE was contrast CT with angiography (74 % of patients)...

INTRODUCTION: Activated protein C resistance (APCr) leads to hypercoagulability and is due, often but not exclusively, to Factor V Leiden (FVL). The aim of this study was to assess the ex vivo and in vitro interference of the direct factor Xa inhibitor rivaroxaban (RIV) on a prothrombinase-based assay for APCr detection. METHODS: An ex vivo study was performed on fresh plasma samples obtained from 44 subjects with FV wild-type and seven with FVL heterozygous, all treated with RIV...

BACKGROUND: Because the venous thromboembolisms (VTEs) due to the coagulation factor V R506Q (FV Leiden) mutation is often seen in Caucasians, the VTE onset in Japan has not been reported. CASE PRESENTATION: A 34-year-old man from north Africa experiencing sudden dyspnea went to a hospital for advice. The patient had pain in his right leg and a high plasma D-dimer level. A contrast-enhanced computed tomography scan revealed a contrast deficit in the bilateral pulmonary artery and in the right lower extremity...

BACKGROUND: In patients with venous thromboembolism (VTE) and factor V Leiden (FVL) or prothrombin 20210G-A mutation (PTM), the influence of gender on outcome has not been consistently studied. METHODS: We used the RIETE (Registro Informatizado Enfermedad TromboEmbolica) database to assess the existence of gender differences in the rate of VTE recurrences (deep vein thrombosis [DVT] or pulmonary embolism [PE]) or major bleeding during the course of anticoagulation and after its discontinuation in FVL and PTM carriers...

Thrombophilia is a multifactorial disorder involving environmental and genetic factors. Well‑known factors that result in predisposition to congenital disorders associated with thrombophilia include antithrombin deficiency, protein C and S deficiency, Factor V Leiden mutation, abnormal prothrombin and antiphospholipid syndrome. The present study revealed an association between a mutation of the F2 gene, which codes for coagulation factor II, thrombin, and the risk of thrombophilia in a Han Chinese family, of which four members (I‑2, II‑2, II‑3 and III‑1) had a history of deep venous thromboembolism...

Perinatal stroke causes cerebral palsy and lifelong disability. Specific diseases are definable but mechanisms are poorly understood. Evidence suggests possible associations between arterial perinatal stroke and prothrombotic disorders but population-based, controlled, disease-specific studies are limited. Understanding thrombophilia in perinatal stroke informs pathogenesis models and clinical management. We conducted a population-based, prospective, case-control study to determine the association of specific perinatal stroke diseases with known thrombophilias...

Multiple brain abscesses in an immunocompetent patient is a challenging clinical problem in the medical world despite advances in imaging techniques, laboratory diagnostics, surgical interventions, and antimicrobial treatment. It is a clinical entity that typically tends to occur in the presence of known predisposing factors. Clinicians seek to determine the potential risk factors responsible for the development of brain abscess because it is very crucial for management of this life-threatening condition. At times, like in our case, there are clinical situations where it is difficult to reveal any traditional risk factors...

BACKGROUND: A growing body of literature suggests that migraineurs, particularly those with aura, have an increased risk for ischemic stroke, but not via enhanced atherosclerosis. The theory that micro-emboli induced ischemia provokes cortical spreading depression (ie, symptomatic aura) in migraineurs but transient ischemic attacks in others highlights a potential role for hypercoagulability as a link between migraine (with aura) and stroke. AIM: Our objective is to summarize the literature evaluating the association of migraine with various acquired or inheritable thrombophilic states, including those related to elevated estrogen levels, endothelial activation and dysfunction, antiphospholipid antibodies (aPL), deficiency of coagulation inhibitors, and presence of certain genetic polymorphisms...

Normal iron levels are required to prevent thrombocytosis by inhibiting thrombopoiesis. Thrombocytosis is usually associated with a mild iron deficiency and is the result of a lack of inhibition of thrombopoiesis. Study participants were 430 iron deficiency anemia (IDA) patients. Ten (10) mL of venous blood were collected for the subjects. Ferritin analysis was done by ELISA method while Hemogram analysis was done by auto-analyzer. Factor V Leiden, PRTG20210A, and MTHFR C677T genotype analysis was performed by PCR-RFLP method...

Although severe flare of ulcerative colitis (UC) is uncommon, it significantly increases the risk of preterm delivery, low birth weight and other adverse fetal outcomes. It is critical to optimize aggressive medical treatment with both mother and fetal health. Here, we present a case of a 30-year-old woman with a severe flare of UC at the 16th gestational week. The diagnosis of extensive UC was established 8 years ago. From the time she was diagnosed, she had 5 moderate flares successfully treated with oral and topical mesalamine...

BACKGROUND: Cilioretinal arteries (CAs) represent enlargements of microscopic and early established collaterals formed via vasculogenesis between choroidal and retinal circulations. We aimed to investigate whether genetic tendency to thrombosis due to well-known gene polymorphisms may induce CA vasculogenesis in embryonic life. METHODS: We assessed plasminogen activator inhibitor-1 (PAI-1) 4G/5G, methylenetetrahydrofolatereductase (MTHFR), FACTOR V LEIDEN and PROTHROMBIN gene polymorphisms on 130 patients [82/48 females/males; Median age: 57 (18-84) with visible CAs and 100 (64/36: female/male; Median age: 55 (19-90)] without visible CAs...

The antiphospholipid antibody syndrome is defined by the presence of antiphospholipid antibodies in patients with recurrent venous or arterial thromboembolism (1). SAPHO syndrome is a rare disease, characterized by specific clinical manifestations of synovitis, acne pustulosis, hyperostosis, and osteitis. It is a disease that manifests with a combination of osseous and articular manifestations associated with skin lesions (2). Venous thrombosis complicating SAPHO syndrome seems to be uncommon with an unclear pathogenesis (3-9)...

BACKGROUND AND OBJECTIVE: High altitude may be a factor associated with cerebral venous thrombosis (CVT). As our knowledge of CVT at high altitude is limited, it was decided to pool such information from the available case studies to determine whether high altitude can predispose to CVT. METHODS: A systematic review of the literature was performed for cases reporting CVT at high altitude. Searches of the PubMed database (up to July 2016) were performed for publications, using 'cerebral venous thrombosis' and 'high altitude' as keywords...

BACKGROUND: Individuals with factor V Leiden or prothrombin G20210A mutations are at a higher risk to develop venous thromboembolism. However, the influence of these polymorphisms on patient outcome during anticoagulant therapy has not been consistently explored. METHODS: We used the Registro Informatizado de Enfermedad TromboEmbólica database to compare rates of venous thromboembolism recurrence and bleeding events occurring during the anticoagulation course in factor V Leiden carriers, prothrombin mutation carriers, and noncarriers...

Background: Investigators frequently encounter continuous outcomes with plenty of values clumped at zero called semi-continuous outcomes. The Gensini score, one of the most widely used scoring systems for expressing coronary angiographic results, is of this type. The aim of this study was to apply two statistical approaches based on the categorization and original scale of the Gensini score to simultaneously assess the association between covariates and the presence and severity of coronary artery disease (CAD)...

Inherited thrombophilia is a blood coagulation disorder that increases the risk for venous thromboembolism (VTE). During the last decades, the practice of testing has evolved from testing selected populations, leading to high perceived risks, to broad testing for various conditions that included VTE, arterial thrombosis, and pregnancy complications. Because results of such tests usually do not guide treatment decisions, not testing patients with VTE for inherited thrombophilia is on the "Choosing Wisely" list endorsed by multiple specialty societies, including ASH...
