Prognostic Factors in Hemodialysis Patients Undergoing Endovascular Treatment for Critical Limb Ischemia due to Isolated Below-the-Knee Disease.

Aim: To investigate the prognosis and to clarify the predictors of both patient and limb survival among hemodialysis (HD) patients with critical limb ischemia (CLI) due to isolated below-the-knee (BK) disease.

Methods: An observational cohort study, analyzing a total of 546 HD patients with 681 limbs who underwent endovascular treatment (EVT) for CLI with isolated BK disease at 11 hospitals in Japan between March 2004 and June 2011, was performed.

Results: The mean patient age was 69.

Serum iron levels as a new biomarker in chemotherapy with leucovorin and fluorouracil plus oxaliplatin or leucovorin and fluorouracil plus irinotecan, with or without molecularly-targeted drugs.

Serum iron levels have been reported to increase following the administration of various anticancer drugs. An increase in serum iron levels during therapy with leucovorin and fluorouracil plus oxaliplatin (FOLFOX) or leucovorin and fluorouracil plus irinotecan (FOLFIRI) was also observed. The aim of this study was to investigate the correlation between serum iron levels and prognosis in advanced colorectal cancer (CRC) patients treated with FOLFOX/FOLFIRI ± molecularly-targeted drugs.

Patient factors against stable control of warfarin therapy for Japanese non-valvular atrial fibrillation patients.

Introduction: Effectiveness and safety of warfarin therapy for non-valvular atrial fibrillation (NVAF) patients are strongly associated with its stability presented such as time in therapeutic range (TTR) of PT-INR. However, the factors that affect TTR have not been fully elucidated in Japan where majority of patients are controlled within the range of 1.6-2.

Individualized chemotherapy for colorectal cancer based on the collagen gel droplet-embedded drug sensitivity test.

The leucovorin (FOL) and fluorouracil (5-FU) plus oxaliplatin (l-OHP; FOLFOX) or FOL and 5-FU plus irinotecan (SN-38; FOLFIRI) regimens with or without molecularly-targeted drugs are widely used as first-line chemotherapy in the treatment of advanced colorectal cancer (CRC). Whether FOLFOX or FOLFIRI is administered first is not significant, however, it is essential that full administration of the targeted dosages of all 3 drugs, 5-FU, l-OHP and SN-38, is achieved. However, this is not always possible and second-line chemotherapy must be abandoned in certain cases.

Efficacy and effect on plasma B-type natriuretic peptide concentration of losartan-hydrochlorothiazide for hypertension uncontrolled by losartan-based therapy: subanalysis of a Multicentre Prospective Observational Study.

Many patients with hypertension have difficulty achieving their target blood pressure (BP). Therefore combination therapy, for example with an angiotensin II receptor blocker (ARB) and a diuretic, may be recommended. We previously evaluated the efficacy and safety of losartan (LOS) 50 mg - hydrochlorothiazide (HCTZ) 12.

Good response to leucovorin and fluorouracil plus oxaliplatin and cetuximab therapy in a patient with metastatic ascending colon cancer harboring a KRAS p.G13D mutation.

The effectiveness of cetuximab (Cmab) against KRAS p.G13D mutant-type tumors has been reported. In this study, we report a case of metastatic ascending colon cancer harboring a KRAS p.

Antihypertensive efficacy of the losartan/hydrochlorothiazide combination and its effect on plasma B-type natriuretic peptide in hypertensive patients uncontrolled by angiotensin II type 1 receptor antagonist-based therapy: a multicentre prospective observational study.

Background And Objectives: Although strict blood pressure (BP) control is effective in the prevention of cardiovascular events, it is often insufficient in many hypertensive patients. B-type natriuretic peptide (BNP) has been shown to be associated with cardiovascular events. We investigated the effects of the losartan/hydrochlorothiazide combination on BP and plasma BNP in hypertensive patients uncontrolled by an angiotensin II type 1 receptor antagonist (angiotensin receptor blocker [ARB])-based therapy.

[Pulmonary large cell carcinoma contiguous to bullae with massive bullous hematoma and hemoptysis; with special reference to 20 cases of Japanese reports].

A 50-year-old man with continuous hemosputa and large hematoma of left upper lobe contiguous to bilateral emphysematous bullous disease was admitted for surgery to stop hemorrhage and to resect left lung hematoma and multiple bullae. Bullectomy and neodymium yttrium aluminum garnet (Nd-YAG) laser irradiation to bullae of left upper lobe performed successfully with maximum preserved pulmonary function of it. Pathological examination, however, revealed anaplastic carcinoma inside bulla of S(1+2)c with minimal invasion into adhered parietal pleura (p 3).

[Two cases of hemodialysis patients with absolute hypoparathyroidism or normal parathyroid function who were suffering from prostate carcinoma].

In recent years, the incidence of prostate carcinoma in patients with renal failure is increasing. But it is difficult to diagnose the occurrence of this neoplasm because of decrease of urinary volume in these patients. Two hemodialysis patients (age: 64, 68 years, the duration of hemodialysis: 10, 8 years) suffering from prostate carcinoma were treated with androgen deprivation therapy, which accelerates bone resorption.

Possible involvement of macrophage-colony stimulating factor in the pathogenesis of cardiac dysfunction in hemodialysis patients.

In patients with end stage renal disease on hemodialysis (HD), left ventricular (LV) function is frequently impaired. However, the mechanism of the LV dysfunction is totally unknown. It has been suggested that overproduction of nitric oxide induced by inflammatory cytokines may contribute to the LV dysfunction in some diseased states.

Changes of bone remodeling immediately after parathyroidectomy for secondary hyperparathyroidism.

Background: Successful parathyroidectomy for secondary hyperparathyroidism alleviates bone pain and is followed by the development of hypophosphatemia and hypocalcemia, as well as an increase in bone mineral density. An increase in osteoblast surface (Ob.S/BS) is not observed several months after surgery.

Development of low-turnover bone diseases after parathyroidectomy and autotransplantation.

Parathyroidectomy and immediate autotransplantation (PTX-AT) has been shown to decrease bone pain and increase bone mineral density. However, adynamic bone disease (ABD) has been predicted to develop if the serum intact parathyroid hormone (i-PTH) level remains lower than normal for a long period of time. Therefore, we investigated the bone histology of patients whose serum i-PTH levels did not increase over 70 pg/mL for 1 year after PTX-AT.

Early changes of bone histology and circulating markers of bone turnover after parathyroidectomy in hemodialysis patients with severe hyperparathyroidism.

Aims: There have so far been no reports on the changes in bone histology in the early period after parathyroidectomy and autografting (PTX-AG). We investigated the effects of PTX-AG on bone histology during the initial 12 weeks after undergoing these surgical procedures.

Materials And Methods: We performed bone histomorphometry 3 times (before as well as 4 and 12 weeks after PTX-AG) in 6 patients and 2 times (before and 4 weeks after PTX-AG) in 3 hemodialysis patients.

[Usefulness of exercise echocardiography in ischemic heart disease: comparison with exercise cardiac scintigraphy].

Exercise echocardiography and exercise thallium-201 (201Tl) single photon emission computed tomography (SPECT) were performed in 152 patients with suspected coronary artery disease, including 61 patients with old myocardial infarction. All patients underwent coronary arteriography, and coronary artery disease was defined as > or = 75% diameter stenosis. Digital two-dimensional echocardiography was performed before and after the treadmill exercise test, and wall motion abnormality was evaluated using quad-screen.

Successful surgical treatment for hepatic encephalopathy caused by a pancreatic siphon: report of a case.

We report herein the case of a 39-year-old man with cirrhosis of the liver who developed hepatic encephalopathy and progressive diabetes caused by a pancreatic siphon after undergoing a distal splenorenal shunt (DSRS) for a variceal hemorrhage. Radiologic occlusion was judged to be inappropriate because of the extensive DSRS. The DSRS was surgically closed 6 years after the operation to restore portal perfusion.

Ischemic heart disease 31 years after possible Kawasaki disease.

We present a 38-year-old woman who had experienced an acute febrile illness lasting more than 1 week at the age of 6, with erythema on the palms and soles following skin desquamation in the subacute phase and skin eruption. Thirty one years later, she experienced acute myocardial infarction and episodes of angina pectoris. She had no coronary risk factors or autoimmune diseases.

Immediate relief of spontaneous coronary artery spasm by intracoronary infusion of an endothelium-dependent vasodilator, substance P.

This report describes a 45-year-old Japanese man who had episodes of anginal chest pain on effort. Coronary arteriography in the baseline state revealed subtotal occlusion in the mid-portion of the left anterior descending coronary artery. After intracoronary infusion of an endothelium-dependent vasodilator, substance P, the subtotal occlusion was immediately abolished.
