A method of "Noninjecting Resection using Bipolar Soft coagulation mode; NIRBS" for superficial non-ampullary duodenal epithelial tumor: a pilot study.

Background: Complete endoscopic resection of superficial non-ampullary duodenal epithelial tumors (SNADETs) is technically difficult, especially with an extremely high risk of adverse event (AE), although various endoscopic resection methods including endoscopic mucosal resection (EMR), underwater EMR (UEMR), and endoscopic submucosal dissection (ESD) have been tried for SNADETs. Accordingly, a novel simple resection method that can completely resect tumors with a low risk of AEs should be developed.

Aims: A resection method of Noninjecting Resection using Bipolar Soft coagulation mode (NIRBS) which has been reported to be effective and safe for colorectal lesions is adapted for SNADETs.

Takotsubo cardiomyopathy in Guillain-Barré syndrome.

Background And Purpose: Takotsubo cardiomyopathy (TCM) is a serious autonomic complication of Guillain-Barré syndrome (GBS). However, the association between TCM and GBS has not been investigated in detail. We investigated the characteristics of GBS patients with TCM (GBS-TCM).

Esophageal intramural pseudodiverticulosis.

Esophageal intramural pseudodiverticulosis (EIPD) is a disease of unknown pathogenesis characterized by usually systemic, cystic dilatation of the excretory ducts of esophageal submucosal glands. In this article, I review the epidemiology, clinical manifestations, endoscopic findings, esophagographic findings, and histopathology of EIPD. I also discuss the etiology and possible pathogenesis of EIPD based on my experiences with this disease and a review of the literature.

Evaluation of a new method, "non-injection resection using bipolar soft coagulation mode (NIRBS)", for colonic adenomatous lesions.

Background/aims: Endoscopic resection of all colorectal adenomatous lesions with a low complication rate, simplicity, and negative residuals is challenging. Hence, we developed a new method called "non-injection resection using bipolar soft coagulation mode (NIRBS)" method, adapted for colorectal lesions. In addition, we evaluated the effectiveness of this method.

Platypnea-Orthodeoxia: An Effective Diagnostic Tool for Hepatopulmonary Syndrome With Chronic Obstructive Pulmonary Disease.

Hepatopulmonary syndrome (HPS) shows progressive dyspnea resulting from intrapulmonary atrioventricular shunts in liver cirrhosis. The comorbidity of chronic lung disease often hampers the diagnosis of progressive dyspnea in patients with HPS. Therefore, a comprehensive approach to the determination of dyspnea is required.

[The Relationship between Sarcopenia and Survival after Cabazitaxel Treatment for Castration-Resistant Prostate Cancer].

Sarcopenia is a known predictor of overall survival in several diseases. We investigated the relationship between sarcopenia and outcome of treatment with cabazitaxel (CBZ) for castration-resistant prostate cancer (CRPC) by a retrospective analysis of 37 patients, who were given cabazitaxel at our hospital, from December 2014 to November 2020. The skeletal muscle mass was evaluated using the Psoas Muscle Mass Index (PMI: psoas major muscle area at the level of the third lumber vertebra (cm²)/height x height (m²)) through computed tomography images.

Does Atherosclerosis Have Negative Impacts on Early Adjacent Segment Degeneration After Posterior Lumbar Interbody Fusion?

Study Design: Retrospective study.

Objective: To examine whether atherosclerosis has negative impacts on early adjacent segment degeneration (ASD) after posterior lumbar interbody fusion using traditional trajectory pedicle screw fixation (TT-PLIF).

Methods: The subjects were 77 patients who underwent single-level TT-PLIF for degenerative lumbar spondylolisthesis.

Three-dimensional analysis of displacement characteristics of dorsally angulated intra-articular distal radial fractures.

Understanding the complex fragmentation of intra-articular distal radial fractures contributes to achieving anatomical reduction during surgery. This study aimed to clarify three-dimensional displacement patterns of intra-articular fragmentation in dorsally angulated, intra-articular distal radial fractures. We identified five characteristic intra-articular fragments: a key fragment, dorsal ulnar corner, dorsal wall, radial column and anterior radial column.

Early cephalad adjacent segment degeneration after posterior lumbar interbody fusion: a comparative study between cortical bone trajectory screw fixation and traditional trajectory screw fixation.

Objective: Cortical bone trajectory (CBT) screw insertion through a caudomedial starting point provides advantages in limiting dissection of the superior facet joints and reducing muscle dissection and the risk of superior-segment facet violation by the screw. These advantages of the cephalad CBT screw can result in lower rates of early cephalad adjacent segment degeneration (ASD) after posterior lumbar interbody fusion (PLIF) with CBT screw fixation (CBT-PLIF) than those after PLIF using traditional trajectory screw fixation (TT-PLIF). Here, the authors investigated early cephalad ASD after CBT-PLIF and compared these results with those after TT-PLIF.

Long-Term Effect of Pravastatin on Carotid Intima-Media Complex Thickness: The J-STARS Echo Study (Japan Statin Treatment Against Recurrent Stroke).

Background And Purpose: The effect of statins on progression of carotid intima-media complex thickness (IMT) has been shown exclusively in nonstroke Western patients. This study aimed to determine the effect of low-dose pravastatin on carotid IMT in Japanese patients with noncardioembolic ischemic stroke.

Methods: This is a substudy of the J-STARS trial (Japan Statin Treatment Against Recurrent Stroke), a multicenter, randomized, open-label, parallel-group trial to examine whether pravastatin reduces stroke recurrence.

Therapeutic effects of intensive inpatient rehabilitation in advanced Parkinson's disease.

Background: The importance of rehabilitation therapy in Parkinson's disease is well recognized. However, the effects of an inpatient rehabilitation program for advanced Parkinson's disease have not been fully investigated.

Aim: To assess the effects of intensive inpatient rehabilitation.

[A Case of Penile Squamous Cell Carcinoma, Sarcomatoid Subtype].

A 70-year-old man was referred to our department for further examination and treatment of a painless penile mass of about 2cm. The patient first noticed the mass onlya few weeks before presentation. Diagnostic biopsy was interpreted as leiomyosarcoma.

Expression and pathological effects of periostin in human osteoarthritis cartilage.

Background: Osteoarthritis (OA) is one of the most common joint diseases in elderly people, however, the underlying mechanism of OA pathogenesis is not completely clear. Periostin, the extracellular protein, has been shown by cDNA array analysis to be highly expressed in OA, but its function is not fully understood. The purpose of this study was to examine the expression and function of periostin in human OA.
