Derivation and validation of the J-CTO extension score for pre-procedural prediction of major adverse cardiac and cerebrovascular events in patients with chronic total occlusions.

We developed a prediction model of long-term risk after percutaneous coronary intervention (PCI) for coronary chronic total occlusion (CTO) based on pre-procedural clinical information. A total of 4,139 eligible patients, who underwent CTO-PCI at 52 Japanese centers were included. Specifically, 1,909 patients with 1-year data were randomly divided into the derivation (n = 1,273) and validation (n = 636) groups.

Efficacy of drug-coated balloon angioplasty after directional coronary atherectomy for coronary bifurcation lesions (DCA/DCB registry).

Objectives: To evaluate the efficacy and safety of additional drug-coated balloon (DCB) angioplasty after directional coronary atherectomy (DCA) for coronary bifurcation lesions.

Background: The optimal therapy for bifurcation lesions has not been established, even in the drug-eluting stent era. DCA possibly prevents plaque and carina shift in bifurcation lesions by plaque debulking; however, the efficacy of combined DCA and DCB (DCA/DCB) for bifurcation lesions remains unclear.

Cystoscope-Assisted Laparoscopic Enucleation of a Large Progressive Bladder Leiomyoma.

A bladder leiomyoma is a rare and benign bladder tumor. There are no established guidelines for the surgical treatment of this tumor. A transurethral approach for resection or surgical enucleation of the tumor is difficult, especially in patients with a large-sized leiomyoma.

The first case report of polymerase proofreading-associated polyposis in POLD1 variant, c.1433G>A p.S478N, in Japan.

Polymerase proofreading-associated polyposis, caused by germline variants in the exonuclease domains of POLD1 and POLE, is a dominantly inherited rare condition characterized by oligo-adenomatous polyposis and increased risk of colorectal cancer, endometrial cancer and brain tumours. We report the first Japanese case of polymerase proofreading-associated polyposis carrying a POLD1 variant. The proband was a Japanese woman who had undergone resections of early colorectal carcinomas repeatedly and a hysterectomy with bilateral oophorectomy for endometrial cancer, all of which were diagnosed within 2 years after the first colectomy at 49 year old.

Intravascular ultrasound imaging of isolated and non aorto-ostial coronary Takayasu arteritis: a case report.

Background: Isolated coronary Takayasu arteritis is a rare form of ischemic heart disease that typically appears as an aorto-ostial lesion. Although several vascular imaging modalities including ultrasonography, computed tomographic angiography, magnetic resonance angiography or catheter angiography, play crucial roles for diagnosing Takayasu arteritis, the intravascular ultrasound imaging of Takayasu arteritis is not well studied.

Case Presentation: A 55-year-old woman who was diagnosed with heterozygous familial hypercholesterolemia underwent coronary angiography due to effort angina, which showed ostial left anterior descending coronary artery (LAD) stenosis.

Scoring System for Identification of "Survival Advantage" after Successful Percutaneous Coronary Intervention in Patients with Chronic Total Occlusion.

Background: Percutaneous coronary intervention (PCI) is widely used in patients with chronic total occlusion (CTO), but its benefit in improving long-term outcomes is controversial. We aimed to develop a prediction score for grading "survival advantage" conferred by successful results of CTO-PCI and a scoring system for prediction of the influence of CTO-PCI results on major adverse cardiac and cerebrovascular events (MACCEs).

Methods: Follow-up data of 2625 patients who underwent CTO-PCI at 65 Japanese centers were analyzed.

Details on the effect of very short dual antiplatelet therapy after drug-eluting stent implantation in patients with high bleeding risk: insight from the STOPDAPT-2 trial.

Previously we briefly reported the effect of 1-month dual antiplatelet therapy (DAPT) for patients with high bleeding risk (HBR) receiving percutaneous coronary intervention (PCI) in the STOPDAPT-2 trial, but full analysis data have not been available. We conducted post hoc subgroup analysis regarding the effect of very short DAPT for HBR patients in STOPDAPT-2 trial. The primary endpoint was a 1-year composite of cardiovascular (cardiovascular death, myocardial infarction, definite stent thrombosis, or stroke) and bleeding (TIMI major/minor bleeding) outcomes.

Intestinal Behçet disease associated with myelodysplastic syndrome accompanying trisomy 8 successfully treated with abdominal surgery followed by hematopoietic stem cell transplantation: A case report.

Rationale: Intestinal Behçet disease (BD) with myelodysplastic syndrome (MDS) is a rare condition that is resistant to various immunosuppressive therapies. Several cases in which hematopoietic stem cell transplantation (HSCT) was effective for intestinal BD with MDS accompanying trisomy 8 have been reported.

Patient Concerns: We report an 18-year-old female with a 7-year history of BD.

Multidisciplinary pain management program for patients with chronic musculoskeletal pain in Japan: a cohort study.

Introduction: Multidisciplinary pain management is a useful method for treating chronic musculoskeletal pain. Currently, few facilities in Japan offer multidisciplinary pain treatment, especially in the inpatient setting. We implemented a multidisciplinary pain management program based on International Association for the Study of Pain recommendations.

Objective: Preoperative diagnosis and successful management of acute torsion of a subserosal fibroid by using appropriate imaging modalities and single-port laparoscopic surgery.

Case Report: A 44-year-old nulliparous woman presented with lower abdominal pain. Computed tomography and magnetic resonance imaging with contrast enhancement revealed a tumor in the pouch of Douglas with a low contrast at the center and thin-rim enhancement.

Disparity in pre-emptive end-of-life conversation experience caused by subjective economic status among general Japanese elderly people: a cross-sectional study with stratified random sampling.

Objectives: Pre-emptive conversations (PCs) about end-of-life (EOL) preferences are beneficial for both elderly people and their families to understand and share the preferences. However, the factors which promote/inhibit PCs have yet to be clarified. We therefore aimed to determine the factors related to having PCs with hypothesis that age, subjective economic status and subjective health status are associated with having PC experience.

Effect of 1-Month Dual Antiplatelet Therapy Followed by Clopidogrel vs 12-Month Dual Antiplatelet Therapy on Cardiovascular and Bleeding Events in Patients Receiving PCI: The STOPDAPT-2 Randomized Clinical Trial.

Importance: Very short mandatory dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) with a drug-eluting stent may be an attractive option.

Objective: To test the hypothesis of noninferiority of 1 month of DAPT compared with standard 12 months of DAPT for a composite end point of cardiovascular and bleeding events.

Design, Setting, And Participants: Multicenter, open-label, randomized clinical trial enrolling 3045 patients who underwent PCI at 90 hospitals in Japan from December 2015 through December 2017.

MLH1 germline mutation associated with Lynch syndrome in a family followed for more than 45 years.

Background: Lynch syndrome, is an autosomal dominantly inherited disease that predisposes individuals to a high risk of colorectal cancers, and some mismatch-repair genes have been identified as causative genes. The purpose of this study was to investigate the genomic rearrangement of the gene in a family with Lynch syndrome followed for more than 45 years.

Case Presentation: The family with Lynch syndrome is family N, who received colorectal cancer treatment for 45 years.

Exclusive Cerebellar and Leptomeningeal Metastases from Early Gastric Cancer 14 Months after Proximal Gastrectomy: An Autopsy Case Report.

We report a rare autopsy case in which the patient received gastrectomy after an endoscopic diagnosis of early gastric cancer, and had deteriorated due to exclusive metastatic cerebellar tumors identified 14 months after surgery. A 65-year-old male was diagnosed as having a 0-IIc-type early gastric cancer on the posterior wall of the upper stomach by gastrointestinal endoscopy in search of a cause of epigastralgia, and thus received proximal gastrectomy and pyloroplasty. Although the tumor was in the early stages and limited within the mucosal layer, adjuvant chemotherapy was started by using S-1 80 mg daily due to evidence of metastasis into lymph node #3 at the lesser curvature.

Quadricuspid pulmonary valve stenosis treated by transcatheter pulmonary valvuloplasty with inoue balloon catheter.

The quadricuspid pulmonary valve is a relatively common congenital anomaly which is rarely complicated clinically and also tends to be under-diagnosed. The following case report shows a 62-year-old man with exertional dyspnea due to quadricuspid pulmonary valve stenosis that was diagnosed by using electrocardiography-gated multiple detector computed tomography. He was then treated effectively by transcatheter balloon pulmonary valvuloplasty using an Inoue balloon catheter.

A Case of Clitoral Hypertrophy of Unknown Origin.

Clitoral hypertrophy is caused by disorders of sex development and it is observed from birth in most cases. We encountered a patient in whom normal morphology at birth may have acquired deformity and hypertrophy. The patient was a 10-year-old girl with a chief complaint of pudendal deformity.

Ultrashort-Segment Embolization of High-Flow Vessels Using a Coil Packing Technique in an Amplatzer Vascular Plug.

Purpose: To report an experimental study and clinical case using a coil packing technique that hastens occlusion of an Amplatzer Vascular Plug 1 (AVP1) in short-segment embolization of high-flow target vessels.

Technique: An experimental vascular stenosis model was made of 12-mm soft polyvinyl chloride tubing. Under continuous pulsatile flow, a 12-mm AVP1 was deployed in the 4-mm-diameter stenosis.

Long-term use of carvedilol in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention.

Background: Despite its recommendation by the current guidelines, the role of long-term oral beta-blocker therapy has never been evaluated by randomized trials in uncomplicated ST-segment elevation myocardial infarction (STEMI) patients without heart failure, left ventricular dysfunction or ventricular arrhythmia who underwent primary percutaneous coronary intervention (PCI).

Methods And Results: In a multi-center, open-label, randomized controlled trial, STEMI patients with successful primary PCI within 24 hours from the onset and with left ventricular ejection fraction (LVEF) ≥40% were randomly assigned in a 1-to-1 fashion either to the carvedilol group or to the no beta-blocker group within 7 days after primary PCI. The primary endpoint is a composite of all-cause death, myocardial infarction, hospitalization for heart failure, and hospitalization for acute coronary syndrome.

Change of Tinnitus with Xenon Phototherapy of the Stellate Ganglion.

Objective: To develop a treatment for tinnitus called xenon phototherapy of the stellate ganglion (XPSG) and analyze its effect on tinnitus.

Methods: Patients with chronic tinnitus received XPSG. Symptoms were assessed subjectively with tinnitus handicap inventory (THI) and numerical rating scale (NRS).

Short-term outcome of percutaneous coronary intervention with directional coronary atherectomy followed by drug-coated balloon: a preliminary report.

Directional coronary atherectomy (DCA) is a unique technique used in percutaneous coronary intervention (PCI) which involves the removal of plaque from the coronary artery. Treatment with a drug-coated balloon (DCB) appears to be effective, especially when a predilatation of the lesion is performed appropriately. We hypothesize that the combination therapy of DCA with DCB is an effective strategy in PCI.
