Rishi Chopra, Luis R Leon, Nicos Labropoulos
BACKGROUND: Although unprovoked superficial venous thrombosis (SVT) has traditionally been considered a local, benign disorder, recent studies demonstrate that patients with SVT are at significant risk for deep venous thrombosis, pulmonary embolism, and other venous thromboembolism (VTE) events. Nevertheless, clinical management remains widely inconsistent. Moreover, patients with multiple, unprovoked SVTs of noncommunicating anatomic sites have not been previously described, and they may be at even increased risk for adverse outcomes...

BACKGROUND: Heparin-induced thrombocytopenia (HIT) is a drug-induced, immunoglobulin G medicated autoimmune disorder associated with several negative clinical outcomes including increased morbidity, mortality, and increased medical costs. Previous studies have shown associations between comorbid autoimmune diseases, but there is little known about associations between HIT and autoimmunity. PURPOSE: To provide clinical data to suggest an association between HIT and autoimmunity...

BACKGROUND: Acne is a chronic inflammatory skin disorder which may heal with scarring. Tumor necrosis factor alpha (TNF α) and interleukin 1 β (IL-1β) are considered as the main responsible proinflammatory mediators of acne pathogenesis. Oversecretion of these cytokines was found to be associated with TNF α-308 G>A and IL-1β-511 C<T polymorphisms. AIM: To evaluate the association of TNF α-308 and IL-1β-511 gene polymorphisms with acne and postacne scarring susceptibility and acne severity...

BACKGROUND: Published case series have described central hepatic macroregenerative nodules or masses as a common feature of Alagille syndrome. Our experience suggests this regenerative pattern can be seen more generally in cholangiopathic disorders. OBJECTIVE: To define the frequency of central regenerative tissue in Alagille syndrome and other cholangiopathic disorders and to describe the typical appearance of such regenerative tissue. MATERIALS AND METHODS: We conducted a retrospective study of CT and MR imaging performed in children and young adults with cholangiopathic disorders between January 2000 and June 2016...

Objectives: APS is associated with arterial and venous thrombosis. The unfavourable fibrin clot phenotype, including formation of dense and poorly lysable clots, has been reported in thrombotic APS. We investigated whether abnormal plasma clot properties are predictive of recurrent thromboembolism in APS. Methods: We followed 126 consecutive patients with thrombotic APS and 105 control subjects, without APS, matched for thrombotic events. Plasma fibrin clot permeability (Ks), turbidity measurements and clot lysis time were evaluated ⩾5 months after a thrombotic event...

BACKGROUND: Four nonvitamin K antagonist oral anticoagulants (NOACs) have been approved for use in various cardiovascular indications. The direct thrombin inhibitor dabigatran and the direct factor Xa inhibitors apixaban, edoxaban, and rivaroxaban are now increasingly used in clinical practice. For some of these agents, available data from real-world studies support the efficacy and safety data in phase III clinical trials. OBJECTIVES: This review aims to summarize the current status of trials and observational studies of oral anticoagulant use over the spectrum of cardiovascular disorders (excluding venous thrombosis), provide a reference source beyond stroke prevention for atrial fibrillation (AF) and examine the potential for novel applications in the cardiovascular field...

Thrombotic disorders are characterized by an increase in the probability of the formation of unnecessary thrombi that might be due to the activation of the coagulation cascade or the circulating platelets. Platelets or thrombocytes play an essential role in hemostasis but abnormal platelet function leads to the development of a number of cardiovascular complications, including thrombotic disorders. Under pathological conditions, platelets are associated with the development of different thrombotic disorders, including atherosclerosis, arterial thrombosis and stroke, deep venous thrombosis and pulmonary embolism; therefore, platelets are the target of a number of anti-thrombotic strategies...

BACKGROUND: The maxillary artery (MA) has been described as a reliable donor for extracranial-intracranial high-flow bypass. Existing techniques to harvest MA require brain retraction and drilling of the middle fossa (with or without a zygomatic osteotomy), carrying the potential risks of venous bleeding, injury to the branches of the maxillary or mandibular nerves, muscular transection, or temporomandibular junction disorders. OBJECTIVE: To describe a novel technique to expose the MA without bony drilling and with minimal impact to surrounding structures...

BACKGROUND: Acid-base disturbances are frequent in critically ill patients. Arterial blood gas (ABG) is the gold standard in the diagnosis of these disturbances, but it is invasive with potential hazards. For patients with a central venous catheter, venous blood gas (VBG) sampling may be an alternative, less-invasive diagnostic tool. However, the accuracy of a central VBG-based acid-base disorder diagnosis compared to an ABG is unknown. The primary objective of this study was to assess the accuracy of a central VBG-based acid-base disorder diagnosis compared to the "gold standard" ABG in critically ill patients...

Background: Intravenous drug use is associated with progressive kidney disease of several aetiologies. It is associated with behavioural and lifestyle characteristics that make the provision of renal replacement therapies (RRTs) challenging. We observed that patients who use intravenous drugs [people who inject drugs (PWID)] present late to renal services and struggle to engage with treatment. We describe the experience of a UK centre providing renal services to a mixed city and rural population...

Little is known about the correlation between IL-6 and childhood abuse and neglect which may be risk factors for the development of affective disorders in adulthood. The aim of this study was to analyze differences in serum concentrations of IL-6 between patients with major depressive disorder and healthy controls, and to investigate possible correlations with adverse childhood experiences. Peripheral venous blood samples were obtained from 64 patients who fulfilled DSM-IV-R criteria for a current major depressive episode without psychotic symptoms (MDD) and 53 healthy controls, matched for age and gender...

Ocular disease in Behçet's disease is frequent and may be associated with a poor functional prognosis. Uveitis is the most common ocular manifestation in Behçet's disease and represents a diagnostic criterion of the disease. The ocular involvement is inaugural of the disease in 20% of the cases or may develop 2 to 3 years after the beginning of the extraocular signs. The risk of blindness at 5 years is in the order of 15 to 25%, mainly due to macular involvement or retinal vasculitis. Uveitis may be anterior, intermediate, posterior or panuveitis...

Congenital disorders of glycosylation (CDG) are rare inborn diseases of glycan component of N-glycosylated proteins. We report here the case of a 28-year-old patient with CDG syndrome type Ia, who presented with a deep venous thrombosis in the left suro-popliteal vein with no known triggers or antecedents. The patient was treated with rivaroxaban for six months. Blood tests performed after discontinuing anticoagulant treatment showed multiple abnormalities affecting the proteins involved in haemostasis (both coagulation factors and inhibitors), i...

BACKGROUND/AIMS: Recent evidence suggests that impaired cytotrophoblast proliferation and migration are major factors responsible for the development of hypertension in pregnancy. Studies report that von Willebrand factor (vWf) is a specific endothelial damage plasma marker. The aim of this study was to evaluate the relationship between vWf maternal plasma concentration and maternal and fetal Doppler flow measurements in pregnancies complicated by hypertension. It may provide additional insight into the pathophysiology of pregnancy-related hypertension and show the potential method for disease prevention and therapy...
