Effectiveness and safety of low-energy shock wave therapy for digital ulcers associated with systemic sclerosis: a phase 3 pivotal clinical trial.

Objectives: Systemic sclerosis is characterised by ischaemic skin ulcers on the fingertips, and low-energy shock wave therapy is suggested as a novel treatment for ischaemic lesions with angiogenic effects. We aimed to investigate the efficacy and safety of shock wave therapy for skin ulcers in patients with systemic sclerosis.

Methods: In this phase 3 pivotal study, we analysed 60 systemic sclerosis patients with digital ulcers that did not disappear after >4 weeks of existing treatment: 30 patients were treated with extracorporeal shock wave therapy and 30 with conventional treatment.

Spontaneous Regression of Blastic Plasmacytoid Dendritic Cell Neoplasm Following Sepsis by Serratia marcescens: A Case Report and Literature Review.

Spontaneous regression is rare in patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN). An 85-year-old man presented with pancytopenia and skin lesions, and the bone marrow exhibited 79.6% CD4+, CD56+, CD123+, and TCL-1+ abnormal cells, with a normal karyotype; he was thus diagnosed with BPDCN.

A case of TAFRO syndrome, a variant of multicentric Castleman's disease, successfully treated with corticosteroid and cyclosporine A.

We report a case of a 46-year-old woman with fever, pleural effusion, massive ascites, severe edema, hepatosplenomegaly, elevation of serum creatinine level, proteinuria, and severe thrombocytopenia. Her clinical features were compatible with TAFRO syndrome proposed as a variant of multicentric Castleman's disease, that is occasionally associated with poor prognosis. Treatment with corticosteroid improved her symptoms partially.

Interventions for body weight reduction in obese patients during short consultations: an open-label randomized controlled trial in the Japanese primary care setting.

Background: Family physicians should maintain regular contact with obese patients to ensure they effectively reduce their body weight. However, family physicians in Japan have on average only 6 (min) per consultation, and conventional interventions for body weight reduction require a longer consultation or additional manpower. A brief intervention within the limited consultation time available is therefore needed.

Systematic changes in tonic physiological activities during the Concealed Information Test.

Many studies on the Concealed Information Test have focused on phasic physiological changes that are temporally locked to stimulus presentation. However, little is known about changes in tonic, basal physiological levels throughout a stimulus series. This study focused on changes in tonic physiological activities during the CIT.

A novel autoantibody against fibronectin leucine-rich transmembrane protein 2 expressed on the endothelial cell surface identified by retroviral vector system in systemic lupus erythematosus.

Introduction: Anti-endothelial cell antibodies (AECAs) are thought to be critical for vasculitides in collagen diseases, but most were directed against molecules localized within the cell and not expressed on the cell surface. To clarify the pathogenic roles of AECAs, we constructed a retroviral vector system for identification of autoantigens expressed on the endothelial cell surface.

Methods: AECA activity in sera from patients with collagen diseases was measured with flow cytometry by using human umbilical vein endothelial cells (HUVECs).

Neural mechanisms of timing control in a coincident timing task.

Many ball sports such as tennis or baseball require precise temporal anticipation of both sensory input and motor output (i.e., receptor anticipation and effector anticipation, respectively) and close performance monitoring.

Thrombotic microangiopathy presenting with a considerable accumulation of ascites: a case report.

A 46-year-old man presented with fever, thrombocytopenia, and a considerable accumulation of ascites. Although prednisolone and intravenous cyclophosphamide pulse (IVCY) were effective, he experienced recurrence. Renal insufficiency and hemolytic anemia developed subsequently.

Pregnancy-associated thrombotic thrombocytopenic purpura with anti-centromere antibody-positive Raynaud's syndrome.

Thrombotic thrombocytopenic purpura (TTP), scleroderma renal crisis (SRC), and hemolysis, elevated liver enzyme levels, and a low platelet count (HELLP) syndrome display common symptoms that include microangiopathic hemolytic anemia, thrombocytopenia, and renal failure. Therefore, it is important to distinguish between them because their treatments vary: however, the differential diagnosis is sometimes difficult. We report a 32-year-old woman who was referred to our department for further examination of microangiopathic hemolytic anemia, thrombocytopenia, and a slightly elevated serum creatinine level with anti-centromere antibody-positive Raynaud's syndrome in the early puerperal period.

The use of tacrolimus for recurrent lupus enteritis: a case report.

Introduction: Patients with lupus enteritis sometimes experience recurrence. In such cases, the addition of cyclophosphamide to the treatment regimen is recommended. However, an appropriate treatment has not been established in cases where cyclophosphamide failed to prevent the disease.

Peripheral T cell lymphoma with a high titer of proteinase-3-antineutrophil cytoplasmic antibodies that resembled Wegener's granulomatosis.

Here, we present a 54-year-old man with proptosis and swelling below the left eyelid. Laboratory findings showed high levels of PR3-ANCA and histological examination of the first biopsy revealed acute inflammation. Together with the findings of MRI, a diagnosis of WG was made.

Event-related brain potentials during the standard autonomic-based concealed information test.

The concealed information test (CIT) has been used to detect information that examinees possess by means of their autonomic responses. However, the central activities related to these autonomic responses remain unclear. In this study, we simultaneously recorded 128-ch event-related potentials (ERPs) and various autonomic responses (heart rate, respiratory rate, respiratory amplitude, cutaneous blood flow, and skin conductance response) to a critical item (i.

Within-individual discrimination on the Concealed Information Test using dynamic mixture modeling.

Whether an examinee has information about a crime is determined by the Concealed Information Test based on autonomic differences between the crime-related item and other control items. Multivariate quantitative statistical methods have been proposed for this determination. However, these require specific databases of responses, which are problematic for field application.

A new discrimination method for the Concealed Information Test using pretest data and within-individual comparisons.

A latent class discrimination method is proposed for analyzing autonomic responses on the concealed information test. Because there are significant individual differences in autonomic responses, individual response patterns are estimated on the pretest. Then an appropriate discriminant formula for the response pattern of each individual is applied to the CIT test results.

Affective-motivational influences on feedback-related ERPs in a gambling task.

Theories have proposed that both the stimulus-preceding negativity (SPN) and the medial frontal negativity (MFN) reflect affective/motivational processing. We examined the effect of the motivational impact of feedback stimuli on these ERPs using a simple gambling task, focusing on the influence of prior losses and gains on ERPs and choice behavior. Choices were riskier following large losses than following small losses or large gains.

[A study of attentional resource of discrete and gradational allocation strategy using error-related negativity (ERN)].

The error-related negativity (ERN) is a component of the event-related brain potential (ERP) that is associated with action monitoring and error detection. The ERN amplitude reflects attentional resource allocated to error detection. The present study examined whether discrete or gradational allocation strategy of attentional resource in error detection using the ERN amplitude.

Application of the somatic marker hypothesis to individual differences in decision making.

The somatic marker hypothesis (Damasio, Tranel, & Damasio, 1991) is a controversial theory asserting that somatic activities implicitly bias human behavior. In this study, we examined the relationship between choice behaviors in the Iowa Gambling Task and patterns of skin conductance responses (SCRs) within a healthy population. Results showed that low SCRs for appraising the monetary outcome of risky decisions were related to persistence in risky choices.

SS-A/Ro52, an autoantigen involved in CD28-mediated IL-2 production.

An autoantibody against SS-A/Ro52 (Ro52) is most frequently found in the sera of patients with Sjögren's syndrome, systemic lupus erythematosus, and congenital heart block from anti-Ro52 Ab-positive mother. However, the physiological function of the autoantigen SS-A/Ro52 has not yet been elucidated. In this study, we describe the role of Ro52 protein in T cell activation.

CD26-mediated signaling for T cell activation occurs in lipid rafts through its association with CD45RO.

CD26 is a T cell activation antigen that contains dipeptidyl peptidase IV activity and is known to bind adenosine deaminase. The mechanism by which CD26 costimulation potentiates T cell receptor-mediated T cell activation, leading to subsequent exertion of T cell effector function, is still not clearly defined. In this article, we demonstrate that CD26 localizes into lipid rafts, and targeting of CD26 to rafts is necessary for signaling events through CD26.

Error-related brain potentials elicited by vocal errors.

Error-related negativity (ERN) is observed immediately after an error in choice reaction time tasks performed by hand response. We examined whether the ERN occurs in relation to slips of vocalization in the Stroop color word task. In one condition, the subject's vocal responses were masked by continuous pink noise in order to prevent vocalization-related cortical potentials from contaminating the ERN time window.

Expression of gp34 (OX40 ligand) and OX40 on human T cell clones.

gp34, which we previously cloned, is a ligand of OX40 (CD134), a costimulatory molecule involved in T cell activation. To elucidate the role of human OX40 / OX40L interaction, we examined the expression of gp34 (OX40L) and OX40 in normal human hematopoietic cells by using flow cytometry. OX40 expression is observed on activated T cells, while OX40L is expressed in antigen-presenting cells.

Decreased expression of transcription factor GATA-2 in haematopoietic stem cells in patients with aplastic anaemia.

Aplastic anaemia is characterized by reduced haematopoiesis resulting in pancytopenia. It has been speculated that there is an injury in haematopoietic stem cells in the bone marrow; however, the precise nature of the injury has not been elucidated. In this study, the levels of expression of mRNAs for three transcription factors, GATA-2, SCL and AML1, which function in the early stages of haematopoiesis, were examined by quantitative polymerase chain reaction in patients with aplastic anaemia, idiopathic thrombocytopenic purpura (ITP) and normal subjects.

A repressor element in the 5'-untranslated region of human Pax5 exon 1A.

B-cell-specific activator protein (BSAP) encoded by the Pax5 gene plays a critical role during B-cell development. We have analyzed the 5'-flanking region plus the 5'-untranslated region (5'-UTR) of human Pax5 exon1A to clarify its regulatory mechanisms. Functional dissection of these regions by luciferase reporter assays indicated that a cluster of regulatory elements acts as a strong repressor between +320 and +453.
