Livedoid vasculopathy (LV) is a chronic disease with recurrent reticularis and ulcers, mainly affecting the feet and lower legs. The pathogenesis of LV has not been yet thoroughly understood, but thrombosis is thought to play a major role because fibrin deposition within both the wall and lumen of affected vessels is pathologically detected. A 68-year-old woman first presented to our hospital in 2004 with a 6-year history of a reticular rash and ulceration on the lower legs. Screening tests for vasculitis and collagen disease were mostly normal, leading to diagnosis of LV...

We review the most characteristic clinical and histopathologic findings of the cutaneous manifestations of the occlusive nonvasculitic vasculopathic disorders. Clinically, most of these conditions are characterized by retiform purpura. Histopathologic findings consist of occlusion of the vessel lumina with no vasculitis. Different disorders may produce nonvasculitic occlusive vasculopathy in cutaneous blood and lymphatic vessels, including embolization due to cholesterol and oxalate emboli, cutaneous intravascular metastasis from visceral malignancies, atrial myxomas, intravascular angiosarcoma, intralymphatic histiocytosis, intravascular lymphomas, endocarditis, crystal globulin vasculopathy, hypereosinophilic syndrome, and foreign material...

Epigastric pain is a common symptom in the emergency department. Most epigastric pain is not fatal, except in acute myocardial infarction, aortic dissection, and abdominal aneurysm rupture. Epigastric pain can also be the only symptom of isolated spontaneous gastric artery dissection. We report the case of a 51-year-old woman diagnosed with neurofibromatosis who initially presented with only epigastric pain. She was initially misdiagnosed with gastritis, treated conservatively, and discharged. Two hours later, she returned to the emergency department with persistent epigastric pain and rebound tenderness in the epigastric area...

We conducted a prospective study (between November 2013 and January 2015) to identify "foot at risk" in the diabetic renal transplant patients at a Tertiary Care Hospital in India. Patients (151) were divided into three groups: diabetic transplant recipients (n = 42), new onset diabetes after transplantation (NODAT) (n = 59), and controls (nondiabetic renal transplant recipients) (n = 50). Foot neuropathy and vasculopathy were assessed by standard methods. Patients with "at risk" feet were given foot care advice...

PURPOSE: To subsegment the choroid in patients with polypoidal choroidal vasculopathy and to determine whether the ratio of choriocapillaris/Sattler layer thickness to total choroidal thickness is decreased at sites of polypoidal pathology. METHODS: Retrospective, observational, cross-sectional study. A total of 320 eyes of 305 patients with polypoidal choroidal vasculopathy were studied with optical coherence tomography and dye angiography. The ratio of choriocapillaris/Sattler layer thickness to total choroidal thickness was calculated at polypoidal lesion sites in eyes with subfoveal choroidal thickness (SFCT) ≤200 μm...

AIMS: Thrombospondin-1 (TSP1) is a ligand for CD47 and TSP1(-/-) mice are protected from pulmonary hypertension (PH). We hypothesized the TSP1-CD47 axis is upregulated in human PH and promotes pulmonary arterial vasculopathy. METHODS AND RESULTS: We analyzed the molecular signature and functional response of lung tissue and distal pulmonary arteries (PAs) from individuals with (n=23) and without (n=16) PH. Compared to controls, lungs and distal PAs from PH patients showed induction of TSP1-CD47 and endothelin-1/endothelin A receptor (ET-1/ETA) protein and mRNA...

The retina is a complex neurovascular structure that conveys light/visual image through the optic nerve to the visual cortex of the brain. Neuronal and vascular activities in the retina are physically and functionally intertwined, and vascular alterations are consequential to the proper function of the entire visual system. In particular, alteration of the structure and barrier function of the retinal vasculature is commonly associated with the development of vasoproliferative ischemic retinopathy, a set of clinically well-defined chronic ocular microvascular complications causing blindness in all age groups...

BACKGROUND: Although various studies revealed the beneficial effects of statins in post-cardiac transplant patients, these were relatively small and low-powered studies. We performed a meta-analysis of published studies to evaluate the role of statins in post-cardiac transplant patients, specifically examining the effects on hemodynamically significant/fatal graft rejection, coronary vasculopathy, terminal cancer, and overall survival. METHODS AND RESULTS: We searched PubMed, Cochran CENTRAL, and Web of Science databases using the search terms "cardiac transplant" or "heart transplant," and "statin" for a literature search...

Intraocular vascular endothelial growth factor (VEGF) levels play an important role in the pathogenesis of blindness-related diseases, such as age-related macular degeneration (AMD). Here, we aimed to develop a paper-based enzyme-linked immunosorbent assay (P-ELISA) to analyze the suppression of aqueous VEGF concentrations following intravitreal injection (IVI) of anti-VEGF antibody (bevacizumab or ranibizumab). A total of 25 eyes with wet AMD, one with myopic neovascularization, and one with polypoidal choroidal vasculopathy were enrolled in this study...

BACKGROUND: Vascular complications are important causes of cerebral infarction in tuberculous meningitis (TBM).Transcranial Doppler ultrasonography (TCD) is a non-invasive tool that can provide real-time information about cerebral hemodynamics. However, the literature on the role of TCD in the diagnosis or monitoring of vasculopathy associated with TBM is scarce. We explored the role of TCD in the diagnosis and monitoring of TBM-related vasculopathy of the major intracranial arteries...

Cardiac allograft vasculopathy (CAV) was the leading cause of late death in heart transplantation recipients. Matrix metalloproteinase-14 (MMP-14), as a member of the MMPs family, has been reported to play a vital role in coronary vascular lesions of allotransplanted hearts. However, concrete mechanism is still unclear. Herein, we showed that the expression of MMP-14 was different between isografts and allografts. Interestingly, we found MMP-14 could interact with CD44 in allografts. Cluster of differentiation 44 (CD44), as a cell adhesion receptor and is involved in cell migration, caused our interest in MMP-14/CD44 complex in allografts...

Extra-ischaemic (remote) brain heamorrhages after thrombolysis for ischaemic stroke occur in less than 3 % of treated patients, but it worsens prognosis. Little attention has been paid to the location of the haematomas. Among 12 patients with remote brain haemorrhage after thrombolysis, we report three patients with haemorrhage in the cerebellar vermis (25 %), with poor outcome. Previous hypertensive vasculopathy is deemed to be the most plausible cause.

AMD is a major cause of blindness in the elderly. Previous sequencing studies of AMD susceptibility genes have revealed the association of rare coding variants in CFH, CFI, C3 and C9 in European population; however, the impact of rare or low-frequency coding variants on AMD susceptibility in other populations is largely unknown. To identify the role of low-frequency coding variants on exudative AMD susceptibility in a Japanese population, we analyzed the association of coding variants of 34 AMD candidate genes in the two-stage design by a multiplex PCR-based target sequencing method...
