Recent genetic studies identified that the disease-specific G17V RHOA mutation, together with mutations in TET2, DNMT3A, and IDH2, is a hallmark of angioimmunoblastic T cell lymphomas (AITL). The diagnostic value of these mutations is now being investigated. Circulating tumor DNAs (ctDNAs) may offer a non-invasive testing for diagnosis and disease monitoring of cancers. To investigate whether these mutations are useful markers for ctDNAs in AITL and its related lymphomas, we performed targeted sequencing for TET2, RHOA, DNMT3A, and IDH2 in paired tumors and cell-free DNAs from 14 patients at diagnosis...

Takayasu arteritis is a panarteritis of unknown etiology involving the aorta and its main branches, with higher prevalence in women and peak of incidence in the second and third decades of life. Up to 30% of patients have coronary lesions and aortic valve involvement. Presentation mimicking aortic dissection is quite rare. Here described is the case of a young patient, presenting with an acute coronary syndrome associated with severe aortic regurgitation, who underwent emergent surgery with the suspicion of acute aortic dissection...

Aortitis is a broad term describing inflammation of the aorta. The most common causes of aortitis are the large-vessel vasculitides giant cell arteritis and Takayasu arteritis. Other etiologies include aortitis associated with other autoimmune disorders, infectious causes, and paraneoplastic and idiopathic cases. We describe a rare case of a large-vessel arteritis occurring in association with chronic myelomonocytic leukemia (CMML). A 68-year-old female with recent diagnosis of CMML presented to our office for evaluation of abnormal chest computed tomography (CT) that showed inflammation surrounding the entirety of thoracic and abdominal aorta, consistent with aortitis...

We report a young female who presented with saddle-nose and bilateral cauliflower ear deformities along with pyoderma gangrenosum-like ulcers, digital gangrene and pulselessness. Subsequently, she was found to have bilateral conductive hearing loss, a corneal opacity, mild aortic regurgitation and radiological evidence of cavitary changes in lungs and aortoarteritis. Our patient had a constellation of symptoms which posed a diagnostic challenge. Finally, a diagnosis of relapsing polychondritis with several unusual features was made...

Purpose BIRCH was designed to examine the efficacy of atezolizumab, a humanized anti-programmed death-ligand 1 (PD-L1) monoclonal antibody, in advanced non-small-cell lung cancer (NSCLC) across lines of therapy. Patients were selected on the basis of PD-L1 expression on tumor cells (TC) or tumor-infiltrating immune cells (IC). Patients and Methods Eligible patients had advanced-stage NSCLC, no CNS metastases, and zero to two or more lines of prior chemotherapy. Patients whose tumors expressed PD-L1 using the SP142 immunohistochemistry assay on ≥ 5% of TC or IC (TC2/3 or IC2/3 [TC or IC ≥ 5% PD-L1-expressing cells, respectively]) were enrolled...

OBJECTIVE: Glioblastoma (GBM) relapses locally or in a disseminated pattern, and is highly resistant to chemo-radiotherapy. Although dissemination is associated with poor prognosis for GBM patients, the clinico-pathological factors that promote dissemination have not been elucidated. Glypican-1 (GPC-1) is a heparin sulfate proteoglycan that is attached to the extracytoplasmic surface of the cell membrane and regulates cell motility. The aim of this study was to determine whether GPC-1 expression correlated with GBM dissemination and patient prognosis...

BACKGROUND: Takayasu arteritis is a granulomatous panarteritis that predominantly affects the aorta and its major branches. The initial manifestations of this large-vessel vasculitis are usually nonspecific; however, as the disease progresses, typical symptoms of arterial occlusion, aneurysmal formation, and vascular pain become evident. Ischemic ocular complications of Takayasu arteritis which could lead to complete loss of vision are not uncommon and depend on the obliterated portion(s) of carotid(s), the intensity and rate of progression of ocular vascular insufficiency, and sufficiency of the collateral blood supply to the eye...

A 38-year-old woman developed disturbance of consciousness and quadriplegia. Magnetic resonance images showed scattered acute infarcts in both hemispheres and bilateral occlusion of the intracranial artery (ICA). Immediate mechanical thrombectomy restored the patency of the ICA. Contrast-enhanced computed tomography revealed bilateral wall thickening of the abdominal aorta and the iliac arteries. This finding and an elevated erythrocyte sedimentation rate supported the diagnosis of Takayasu arteritis. Here, we thus report a rare case of Takayasu arteritis with acute bilateral occlusion of the internal carotid arteries...

Fabry disease is an X-linked lysosomal storage disorder caused by a lack of α-galactosidase A activity, which leads to the accumulation of globotriaosylceramide in various organs. A complete lack of α-galactosidase A activity in a hemizygous male is the classical phenotype, and some hemizygous males show primarily cardiac and/or renal symptoms that appear in adulthood; this is called the variant type or the late-onset type. The kidney and heart are the major target organs, with damage to these organs related to mortality...

PURPOSE OF REVIEW: The review aims to summarize the recent findings in vasculitis that may have an impact in our understanding or management of these diseases. RECENT FINDINGS: We are learning more about monogenic diseases that closely mimic the pediatric vasculitides. Deficiency of adenosine deaminase 2 can present with a polyarteritis nodosa (PAN)-like picture and should be included in the differential of all pediatric cases of PAN with a family history or in cases with early stroke, or in cases resistant to conventional therapy...

The aim of this study was to evaluate the stability of implant/interconnected porous calcium hydroxyapatite complex (implant/IPCHA-complex) under functional loading. Implant/IP-CHA-complexes were placed into the mandibles of four Beagle-Labrador hybrid dogs (complex-group). On the other side, an implant was placed directly (control-group). To subject the loading, the animals were fed a hard diet throughout the loading phase of 5 months. The implant stability quotients (ISQs) and bone implant contact (BIC), and histological evaluations were performed...

Pseudohypoaldosteronism type II (PHAII) is characterized by hyperkalemia and hypertension despite a normal glomerular filtration rate. Abnormal activation of the signal cascade of with-no-lysine kinase (WNK) with OSR1 (oxidative stress-responsive kinase 1)/SPAK (STE20/SPS1-related proline/alanine-rich kinase) and NCC (NaCl cotransporter) results in characteristic salt-sensitive hypertension. Thus, inhibitors of the WNK-OSR1/SPAK-NCC cascade are candidates for a new class of antihypertensive drugs. In this study, we developed novel inhibitors of this signal cascade from the 9-aminoacridine lead compound 1, one of the hit compounds obtained by screening our chemical library for WNK-SPAK binding inhibitors...

PURPOSE: Focal cortical dysplasia (FCD) is intrinsically epileptogenic, and an MRI-visible lesion typically constitutes the core part of the epileptogenic zone. We aimed to identify ictal EEG patterns that represent the epileptogenic zone by using subdural electrodes placed over the MRI-visible FCD lesion. METHODS: We selected seven patients with frontal lobe epilepsy caused by pathologically proven FCD type IIb who underwent preoperative intracranial EEG evaluation with subdural electrodes followed by resection surgery with seizure-free outcome...

INTRODUCTION: Takayasu arteritis (TA) is an uncommon large vessel arteritis. Lesions produced by the inflammatory process can be stenotic, occlusive, or aneurysmal. Vascular changes lead to the main complications, including hypertension, most often due to renal artery stenosis or, more rarely, stenosis of the suprarenal aorta. AIM OF STUDY: Our study will assess the prevalence of hypertension during TA and describe its clinical profile. MATERIAL AND METHODS: Among 279 patients with TA resulting from single center study over a period of 35 years, we collected 128 hypertensive patients...

REVIEW
Francois Chasset, Camille Francès
Dermatologic manifestations are observed in almost all systemic vasculitides, even in large-and medium-vessel vasculitides, although such vessels are not found in the skin. Cutaneous manifestations may be related to a direct skin localization of the systemic vasculitis or a non-specific process associated with the vasculitis. According to the 2012 International Chapel Hill consensus, the two major variants of large-vessel vasculitides are Takayasu arteritis and giant-cell arteritis. In Europe and North America, acute inflammatory nodules or erythema nodosum-like lesions are the most commonly observed skin lesions with Takayasu arteritis...

We extend the concept of statistical symmetry as the invariance of a probability distribution under transformation to analyze binary sign time series data of price difference from the foreign exchange market. We model segments of the sign time series as Markov sequences and apply a local hypothesis test to evaluate the symmetries of independence and time reversion in different periods of the market. For the test, we derive the probability of a binary Markov process to generate a given set of number of symbol pairs...
