Mesenteric phlebosclerosis complicating colonic cancer treated by endoscopic submucosal dissection.

A 67-year old woman with a history of long-term Chinese herb use was admitted to our institution complaining of abdominal pain. Barium enema disclosed rigidity of throughout the proximal colon and a slightly elevated lesion in the transverse colon. Colonoscopy showed diffuse and bronze mucosa in the proximal colon, which was compatible with mesenteric phlebosclerosis.

Clinical outcomes of patients treated using very short duration dual antiplatelet therapy after implantation of biodegradable-polymer drug-eluting stents: rationale and design of a prospective multicenter REIWA registry.

Several studies have demonstrated the safety and feasibility of short (3-6 months) and very short duration (< 2 months) dual antiplatelet therapy (DAPT) in patients with a durable-polymer drug-eluting stent (DP-DES). However, the clinical importance of using very short duration DAPT has yet to be established in patients with a biodegradable polymer drug-eluting stent (BP-DES). The aim of this REIWA registry (multicenter and prospective registry; investigation of clinical outcomes of patients treated with short duration dual antiplatelet therapy after implantation of biodresorbable-polymer drug-eluting stent: a multicenter, prospective registry from Iwate medical university affiliated hospitals) is to determine the safety and feasibility of using 1-month DAPT followed by P2Y12 inhibitor monotherapy in patients after BP-DES implantation.

Factors associated with social support in child-rearing among mothers in post-disaster communities.

Background: Natural disasters have long-term negative impacts on the health and socioenvironmental conditions of a population, affecting the physical environment as well as the relationships within the community, including social networks. Mothers in post-disaster communities may have difficulty receiving social support not only from family members and relatives but also from members of their community, such as people in their neighborhoods. This study focused on mothers with infants and preschool-aged children in post-disaster communities.

Obesity in elementary school children after the Great East Japan Earthquake.

Background: Rikuzentakata was one of the cities most devastated by the Great East Japan Earthquake on 11 March 2011. Many buildings were swept away or destroyed and affected families were placed into temporary housing. The aim of this study was to determine the impact of long-term temporary housing on the body mass index (BMI) of elementary school children living in Rikuzentakata City.

CHADS and modified CHADS-VASc scores for the prediction of congestive heart failure in patients with nonvalvular atrial fibrillation.

Background & Purpose: We have conducted a retrospective observational study to analyze the correlation between the CHADS score, the modified CHADS-VASc (mCHADS-VASc) score, and the incidence of all-cause death and congestive heart failure (CHF).

Methods: The study cohort consisted of 292 consecutive patients with nonvalvular atrial fibrillation (NVAF) admitted to our hospital from 2012 to 2014. Electronic medical records were used to confirm medical history including prior heart failure, hypertension, diabetes, stroke, and coronary disease.

How Do Hospital Palliative Care Teams Use the WHO Guidelines to Manage Unrelieved Cancer Pain? A 1-Year, Multicenter Audit in Japan.

It has been reported that pain relief for patients with cancer is suboptimal in Japan. This has been mainly attributed to inadequate dissemination of the World Health Organization (WHO) guidelines for cancer pain management. To better understand this problem, we reviewed how 6 hospital palliative care teams (HPCTs) used the WHO guidelines for unrelieved pain in a 1-year audit that included 534 patients.

Impact of the Japan earthquake disaster with massive Tsunami on emergency coronary intervention and in-hospital mortality in patients with acute ST-elevation myocardial infarction.

Aims: The aims of this study were to evaluate reperfusion rate, therapeutic time course and in-hospital mortality pre- and post-Japan earthquake disaster, comparing patients with ST-elevation myocardial infarction (STEMI) treated in the inland area or the Tsunami-stricken area of Iwate prefecture.

Method And Results: Subjects were 386 consecutive STEMI patients admitted to the four percutaneous coronary intervention (PCI) centers in Iwate prefecture in 2010 and 2011. Patients were divided into two groups: those treated in the inland or Tsunami-stricken area.

Association of a single-nucleotide polymorphism in the immunoglobulin mu-binding protein 2 gene with immunoglobulin A nephropathy.

Immunoglobulin A (IgA) nephropathy is the most common form of primary glomerulonephritis worldwide. The pathogenesis of IgA nephropathy is unknown, but it is certain that some genetic factors are involved in susceptibility to the disease. Employing a large-scale, case-control association study using gene-based single-nucleotide polymorphism (SNP) markers, we previously reported four candidate genes.

[Influence of reagent evaporation on other laboratory reagents and appropriate countermeasures].

When the automated analyzer was first introduced, abnormally high values of urine creatinine and abnormally low values of serum creatinine were seen. It was shown that evaporation of the reducing agent stabilizer(sulfurous acid), which is present in the serum iron measurement kit, was occurring and that the observed low values of serum creatinine were due to consumption of hydrogen peroxide by gasifying sulfurous acid. After the cause was elucidated, the abnormal lowering of creatinine values was prevented.

Transcranial Doppler enhanced thrombolysis for embolic occlusion of major cerebral arteries.

For the treatment of 11 patients with hyperacute embolic occlusion of major cerebral arteries (ten with occlusion of middle cerebral artery and one with occlusion of basilar artery), TCDenhanced thrombolysis (TCDET) was performed in combination with ultrasound irradiation, using diagnostic transcranial Doppler (TCD) (TC2-64B: 2MHz, 100mW/cm(2), pulsed wave) (TCDET group), and the effectiveness of this procedure was compared with that of local intra-arterial fibrinolysis (LIF) in 45 patients with embolic occlusion of the middle cerebral artery (LIF group). Regarding dose of TPA, the LIF group used 1046.7 +/- 607.

Association of single-nucleotide polymorphisms in the polymeric immunoglobulin receptor gene with immunoglobulin A nephropathy (IgAN) in Japanese patients.

Immunoglobulin A nephropathy (IgAN) is a primary glomerulonephritis of common incidence world-wide whose etiology and pathogenesis remain unresolved, although genetic factors are assumed to be involved in the development and progression of this disease. To identify genetic variations that might confer susceptibility to IgAN, we performed a case-control association study involving 389 Japanese IgAN patients and 465 controls. Genome-wide analysis of approximately 80,000 single-nucleotide polymorphisms (SNPs) identified a significant association between IgAN and six SNPs located in the PIGR (polymeric immuoglobulin receptor) gene at chromosome 1q31-q41.

[Superselective fibrinolysis for a middle cerebral artery embolism caused by a left atrial myxoma: case report].

A case of successful treatment by local fibrinolysis of a middle cerebral artery embolism caused by a thrombus from a left atrial myxoma is reported. A 62-year-old woman using a pacemaker and suffering from sick sinus syndrome was admitted on December 29th 1996, complaining of transient restlessness. CT and cerebral angiography revealed no abnormal vascular lesions.

[Clinical study of therapeutic time window of local fibrinolysis for acute middle cerebral artery occlusion].

We evaluated the efficacy of local intra-arterial fibrinolysis (LIF) used in tissue plasminogen activator (t-PA) and its indication for acute middle cerebral artery (MCA) occlusion on angiographic degree of leptomeningeal collateral flow in a series of 26 patients (mean age: 67.2 years old). The occlusion types were classified into three types: (1) M 1 proximal occlusion (N = 8) involved the lenticulostriate arteries (LSA), (2) M 1 distal occlusion (N = 6) without involvement of the LSA to M 2 bifurcation, (3) M 2-3 occlusion (N = 12).
