Neonatal thromboembolism occurs with various predispositions and triggers. Early diagnosis of the thrombosis is challenging and essential for the therapeutic interventions. We herein report two newborns who presented with transient hemi-lower limb ischemia due to (1) arterial thrombosis or (2) a persistent sciatic artery (PSA). The patient with arterial thrombosis showed elevations of fibrin degradation product and D-dimer and received antithrombin and heparin intravenously. The patient with PSA was immediately assessed by a contrast-enhanced computed tomography because of a transient ischemic episode with no evidence of hypercoagulability...

BACKGROUND Cerebral venous thrombosis (CVT) is a rare but fatal complication of hyperthyroidism that is induced by the hypercoagulable state of thyrotoxicosis. Although it is frequently difficult to diagnose CVT promptly, it is important to consider it in the differential diagnosis when a hyperthyroid patient presents with atypical neurologic symptoms. CASE REPORT A 49-year-old Japanese female with unremarkable medical history came in with thyroid storm and multiple progressive ischemic stroke identified at another hospital...

Aims: The objective of our study was to assess the effects of orthostatic challenge on the coagulation system in patients with a history of thromboembolic events and to assess how they compared with age-matched healthy controls. Methods: Twenty-two patients with histories of ischemic stroke and 22 healthy age-matched controls performed a sit-to-stand test. Blood was collected prior to- and at the end of- standing in the upright position for 6 min. Hemostatic profiling was performed by determining thrombelastometry and calibrated automated thrombogram values, indices of thrombin generation, standard coagulation times, markers of endothelial activation, plasma levels of coagulation factors and copeptin, and hematocrit...

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...

Myotonic dystrophy (DM) is a chronic, slowly progressive, autosomal-dominant disorder with delayed muscle relaxation after contraction, distal skeletal muscle weakness, and atrophy. It has a reduced life expectancy due predominantly to respiratory failure or sudden cardiac death. The mortality rate is approximately 7.3 times greater than the general population with a mean age at death of 53 years. Degeneration of the cardiac conduction system causes atrioventricular block, arrhythmias, and ventricular failure...

Amyloid-β related angiitis (ABRA) is a rare complication of cerebral amyloid angiopathy in which amyloid-β (Aβ) deposition in the leptomeningeal and cortical vessels is associated with vasculitis characterized by transmural lymphohistiocytic, often granulomatous, inflammation. Patients usually present with acute to subacute cognitive dysfunction, headaches, and focal neurologic deficits. We report two cases of ABRA with unusual clinical presentations, including one case with fatal cerebral edema leading to herniation and Duret hemorrhages, and another associated with both lobar and deep parenchymal hemorrhages with intraventricular extension as well as hypercoagulability...

Thromboembolic complications are frequent in the nephrotic syndrome. Arterial localizations have been rarely reported. There is no consensus on their management; it depends on the location and hypercoagulable state. We report a case of acute lower limb ischemia occurring in children with a history of nephrotic syndrome, complicated by toes necrosis. The diagnosis was made by Doppler ultrasonography. Thrombectomy was performed and the patient received an anticoagulant treatment. Local cares have improved the local state, avoiding surgical necrosectomy...

BACKGROUND: Antiphospholipid syndrome is an autoimmune, hypercoagulable state that is caused by antiphospholipid antibodies. Anticardiolipin antibodies, anti-β2 glycoprotein-I, and lupus anticoagulant are the main autoantibodies found in antiphospholipid syndrome. Despite the amassed body of clinical knowledge, the risk of obstetric complications that are associated with specific antibody profile has not been well-established. OBJECTIVE: The purpose of this study was to assess the risk of obstetric complications in women with primary antiphospholipid syndrome that is associated with specific antibody profile...

Previously, we have found that intracellular calcium homeostasis is altered in platelets from an experimental model of liver cirrhosis, the bile-duct ligated (BDL) rat; these alterations are compatible with the existence of a hypercoagulable state. Different studies indicate that cholestatic diseases are associated with hyperhomocysteinemia; thus, we hypothetized that it could contribute to those platelet alterations. In the present study, we have investigated the role of homocysteine (HCY) in platelet aggregation and calcium signaling in the BDL model...

Varicella infection is common in children caused by varicella-zoster virus (VZV). VZV is known to cause cerebral arterial vasculopathy and antibody-mediated hypercoagulable state leading to thrombotic complications in children. Such complications in adults are very rare. We report three cases that represent the unseen face of primary varicella infection in adults. Simultaneous involvement of cortical venous sinus thrombosis and deep vein thrombosis leading to clot in right atrium and pulmonary embolism in first case; cortical venous sinus thrombosis in second case; and deep vein thrombosis in third case...

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...

Trousseau's syndrome refers to cerebral infarction associated with hypercoagulability caused by cancer. Here, we report a case of Trousseau's syndrome in a patient with pancreatic cancer undergoing surgery. A 71-year-old woman was diagnosed with pancreatic head cancer with portal vein invasion; she underwent pancreaticoduodenectomy combined with portal vein resection. Pathological examination showed poorly differentiated adenocarcinoma with para-aortic lymph nodal metastasis. Although the patient had an uneventful postoperative course, she suddenly developed right hemiplegia and dysarthria 6 weeks after surgery, resulting in multiple cerebral infarctions scattered over both hemispheres...

Acute myocardial infarction (AMI) is rare in young adults. We present a case of a 29-year-old black woman who presented with an acute onset of chest pain while sleeping. Anterior wall ST-elevation AMI was diagnosed based on clinical presentation, electrocardiographic findings, and elevated cardiac biomarkers. Coronary angiography revealed a totally occluded proximal left anterior descending artery. The obstructing lesion, thrombus, was removed. There was no evidence of atherosclerotic disease or dissection...
