Heyde-like syndrome occurring for the first time following aortic valve replacement with a bioprosthesis: a case report.

Background: Heyde's syndrome is known as a combination of gastrointestinal (GI) bleeding and aortic valve stenosis. However, there are no reports of an association between GI bleeding and bioprosthetic valve stenosis initially occurred after aortic valve replacement (AVR), even though there are several reports that GI bleeding due to native aortic valve stenosis disappeared after AVR, and GI bleeding recurred due to bioprosthetic valve stenosis or patient-prosthesis mismatch.

Case Presentation: An 80-year-old woman who was on hemodialysis for 13 years had undergone AVR with a bioprosthetic valve for aortic regurgitation 3 years prior.

Total arch replacement for the enhanced-fibrinolytic-type disseminated intravascular coagulation patient with endoleak after thoracic endovascular aortic repair for aortic dissection.

Background: Endoleaks after stent graft treatment can cause disseminated intravascular coagulation (DIC), leading to a bleeding tendency.

Case Presentation: A 69-year-old man received thoracic endovascular aortic repair (TEVAR) for acute type B aortic dissection. After that, he developed bleeding tendency, and the diameter of his distal aortic arch increased.

Multicenter retrospective analysis of clinicopathological features and prognosis of oral tongue squamous cell carcinoma in adolescent and young adult patients.

The medical records of 101 AYA patients and 175 control patients with OTSCC who underwent surgery were reviewed. Variables related to prognosis and their clinicopathological associations were analyzed.

Nationwide surveillance of AIDS-defining illnesses among HIV patients in Japan from 1995 to 2017.

Objectives: The accurate prevalence of acquired immunodeficiency syndrome (AIDS)-defining illnesses (ADIs) in human immunodeficiency virus (HIV)-infected patients has not been well investigated. Hence, a longitudinal nationwide surveillance study analyzing the current status and national trend of opportunistic complications in HIV-infected patients in Japan is warranted.

Methods: A nationwide surveillance of opportunistic complications in HIV-infected patients from 1995 to 2017 in Japan was conducted.

Rab3a, a small GTP-binding protein, is required for the stabilization of the murine leukaemia virus Gag protein.

We recently identified a CD63-interacting protein to understand the role of CD63 in virion production of the human immunodeficiency virus type 1, and we have found that Rab3a forms a complex with CD63. In this study, we analysed the effect of Rab3a on virion production of the murine leukaemia virus (MLV), which is another member of the retrovirus family. We found that Rab3a silencing induced lysosomal degradation of the MLV Gag protein, and recovery of the Rab3a expression restored the level of the Gag protein through a complex formation of MLV Gag and Rab3a, indicating that Rab3a is required for MLV Gag protein expression.

Laparoscopic Splenectomy in a Patient with Sclerosing Angiomatoid Nodular Transformation.

Edge-to-edge repair for mitral regurgitation associated with isolated double-orifice mitral valve.

We report the case of a patient with severe mitral regurgitation who was diagnosed with double-orifice mitral valve by preoperative transthoracic and transoesophageal echocardiography. During surgery, it was revealed that the mitral valve was divided into 2 orifices, anterolateral and posteromedial, by a fibrous bridging tissue that was supported by the chordae tendineae originating from an accessory middle papillary muscle. The posterior scallop of the anterolateral orifice was prolapsed due to chordal elongation.

Surgical Repair of Subacute Right Ventricular Perforation after Pacemaker Implantation.

We report an 84-year-old woman who presented with right ventricular perforation 4 days after pacemaker implantation for syncope due to sick sinus syndrome. Median sternotomy revealed no pericardial effusion, but the pacing lead had penetrated the right ventricle and pericardium. When the pleura was opened, the tip of the lead was seen in the visceral pleura.

A case of a quadricuspid aortic valve identified preoperatively using transthoracic echocardiography.

Quadricuspid aortic valve is an extremely rare congenital heart anomaly that often causes valve incompetence, requiring surgical intervention. Care must be taken to avoid surgical complications in patients with quadricuspid aortic valve; thus, preoperative diagnosis is important. A 76-year-old man presented with exertional dyspnea due to aortic regurgitation.

Efficacy and safety of flecainide for ventricular arrhythmias in patients with Andersen-Tawil syndrome with KCNJ2 mutations.
