Technical Pitfalls and Tips of Management for Critical Limb Ischemia by Distal Bypass Using the Autogenous Veins.

It is a clear fact that many complications in surgical treatment, not just in cardiovascular surgery, are caused by things related to surgical techniques. In other words, postoperative problems are already determined by preoperative surgical management and intraoperative surgical operations. This describes strategies to avoid the surgical complications of distal bypass using the autogenous veins for each item.

Prolonged infective SARS-CoV-2 omicron variant shedding in a patient with diffuse large B cell lymphoma successfully cleared after three courses of remdesivir.

We report a case of prolonged shedding of the infective SARS-CoV-2 omicron variant BA.1.1.

Successful allogeneic hematopoietic stem cell transplantation for myelodysplastic neoplasms complicated with secondary pulmonary alveolar proteinosis and Behçet's disease harboring GATA2 mutation.

Myelodysplastic neoplasms (MDS) are defined by cytopenia and morphologic dysplasia originating from clonal hematopoiesis. They are also frequently complicated with diseases caused by immune dysfunction, such as Behçet's disease (BD) and secondary pulmonary alveolar proteinosis (sPAP). MDS with both BD and sPAP is extremely rare, and their prognosis is poor.

Castleman disease (CD) is a lymphoproliferative disorder that manifests as hypergammaglobulinemia and severe inflammation with multiorgan involvement. However, renal involvement has been infrequently described in CD. We present a case of a 63-year-old Japanese male patient with multicentric CD (MCD) in whom kidney involvement, including impaired renal function and massive proteinuria, is present.

New-onset dermatomyositis following COVID-19: A case report.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Most of the infected individuals have recovered without complications, but a few patients develop multiple organ involvements. Previous reports suggest an association between COVID-19 and various inflammatory myopathies, in addition to autoimmune diseases.

Methods: All patients with CAPS who received canakinumab treatment after drug approval in Japan were registered in this non-interventional, observational study. The observation period per patient was two years.

Efficacy of sacubitril/valsartan versus olmesartan in Japanese patients with essential hypertension: a randomized, double-blind, multicenter study.

This phase III study assessed the efficacy and safety of sacubitril/valsartan compared with those of olmesartan in Japanese patients with essential hypertension. Patients (n = 1161, aged ≥20 years) with mild to moderate hypertension (mean sitting systolic blood pressure [msSBP] ≥150 to <180 mmHg) were randomized to receive sacubitril/valsartan 200 mg (n = 387), sacubitril/valsartan 400 mg (n = 385), or olmesartan 20 mg (n = 389) once daily for 8 weeks. The primary assessment was a reduction in msSBP from baseline with sacubitril/valsartan 200 mg vs.

Immunoglobulin A Vasculitis in a Japanese Patient with Complete Familial Mediterranean Fever Carrying MEFV Exon 10 Mutation.

Immunoglobulin A (IgA) vasculitis is a systemic small-vessel vasculitis involving the skin, kidney, joints, and gastrointestinal tract. Familial Mediterranean fever (FMF) is the most common autoinflammatory disease characterized by periodic fever, peritonitis, pleuritis, or arthritis. It is well known that FMF may coexist with vasculitis, especially small and medium vessel vasculitis.

Effect of a multitarget therapy with prednisolone, mycophenolate mofetil, and tacrolimus in a patient with type B insulin resistance syndrome complicated by lupus nephritis.

Type B insulin resistance syndrome (TBIR) is a rare autoimmune disease characterised by autoantibodies targeting insulin receptors. TBIR is often complicated by systemic lupus erythematosus (SLE). We describe the case of a 59-year-old Japanese man with TBIR complicated with lupus nephritis (LN), who presented with nephrotic syndrome and severe hypoglycaemia.

Real-world Safety and Efficacy of Indacaterol/Glycopyrronium in Japanese Patients with Chronic Obstructive Pulmonary Disease: A 52-week Post-marketing Surveillance.

Objective To evaluate the long-term safety and efficacy of indacaterol/glycopyrronium (IND/GLY) in patients with chronic obstructive pulmorary disease (COPD) in a real-world setting in Japan. Methods This 52-week, multicentre, post-marketing surveillance conducted in Japan between December 2013 and August 2019 included patients using IND/GLY for the first time to relieve airway obstructive disorder-related symptoms. Safety outcomes included the incidence of adverse events (AEs), serious AEs (SAEs), adverse drug reactions (ADRs), and serious ADRs during the 52-week period.

Long-term Outcomes of Hypofractionated Stereotactic Radiotherapy for the Treatment of Perioptic Nonfunctioning Pituitary Adenomas.

The efficacy of stereotactic radiotherapy (SRT) has been well established for postoperative residual and recurrent nonfunctioning pituitary adenomas (NFPAs). However, the risk of visual impairment due to SRT for lesions adjacent to the optic pathways remains a topic of debate. Herein, we evaluated the long-term clinical outcomes of hypofractionated stereotactic radiotherapy (HFSRT) for perioptic NFPAs.

[Intracranial Growing Teratoma Syndrome:Case Reports and Literature Review].

Background: Growing teratoma syndrome(GTS)is the progression of a mature teratoma during or following radiochemotherapy for germ cell tumors. We report two surgical cases of GTS. CASE 1: A 24-day-old new-born presented with vomiting and head enlargement.

Small caliber heparin loaded ultrafine microfiber woven graft achieved high patency rate in a preliminary study of canine carotid artery implantation.

Objective: In the past five decades, many small caliber vascular grafts have been developed as bypasses for infrapopliteal or coronary arteries. However, reliable grafts have not been obtained owing to poor patency, mainly caused by early thrombosis or neointimal hyperplasia in the intermediate period after implantation. We developed a novel small caliber heparin-loaded polyethylene terephthalate ultrafine microfiber (HL-PET) graft and evaluated the feasibility to overcome those main causes of graft failure in canine carotid artery implantation.

Cardiovascular safety and effectiveness of vildagliptin in patients with type 2 diabetes mellitus: a 3-year, large-scale post-marketing surveillance in Japan.

: The dipeptidyl peptidase-4 (DPP-4) inhibitor vildagliptin is indicated for type 2 diabetes mellitus (T2DM). However, the long-term safety, effectiveness, and clinical relationship with cardiovascular events of vildagliptin have not been evaluated in Japan.: The authors conducted post-marketing surveillance (PMS) to evaluate the safety and effectiveness of vildagliptin in more than 3000 Japanese T2DM patients for up to 3 years.

A Clampless Aortoprosthetic End to Side Anastomotic Device with Large Diameter Aortic Puncher.

Introduction: To facilitate safe anastomosis of a vascular prosthesis onto the proximal ascending aorta without side clamping, a clampless anastomotic device with large diameter aortic puncher was developed.

Report: First, a vascular prosthesis is anastomosed onto the aorta without making a hole, then the aortic wall within the prosthesis is punched out using the device.

Discussion: After further refinement of the present device, endovascular surgery with debranching could be performed more safely and quickly.
