Utilization of relative evaluation of pancreatic perfusion CT parameters to support appropriate pancreatic adenocarcinoma diagnosis.

Objectives: To investigate the effect of relative evaluation of perfusion computed tomography (PCT) parameters in the diagnosis of pancreatic adenocarcinoma (PAC).

Methods: Of the 117 patients in which PCT was performed (May 2019 to June 2023), 99 patients with mass lesions (MLs), including 50 PAC and 11 patients with mass-forming pancreatitis (MFP), and 15 patients without MLs but with main pancreatic duct (MPD) abnormalities, including 6 PAC and 7 no diagnosis of malignancy (NDM) cases were enrolled in this study. Parameter values were obtained from parametric maps of blood flow (BF), blood volume (BV), and mean transit time (MTT) for the ML and abnormal MPD part (AMP), pancreas and spleen.

Percutaneous Coronary Intervention for Aorto-Ostial Chronic Total Occlusion: Evaluating Lesion Complexity and Procedural Outcomes.

Background: PCI for aorto-ostial CTO remains challenging. The techniques for guidewire in aorto-ostial CTO may differ from those used in non-aorto-ostial CTOs, influenced by clinical and angiographic characteristics.

Objectives: This study aimed to assess the technical aspects and outcomes of percutaneous coronary intervention (PCI) in patients with aorto-ostial chronic total occlusion (CTO).

Virtual Reality-Guided Simulation for Percutaneous Coronary Intervention in a Patient with Anatomical Anomalies: A Case Report.

BACKGROUND Virtual reality (VR)-guided GC simulation for patients with anatomical anomalies using cardiac computed tomography (CT) has been recently reported. Rotational atherectomy (RA) for the left circumflex (LCX) ostium is challenging due to the tortuous anatomy, acute angulation, and variable vessel size compared to other lesions. The appropriate positioning and coaxiality of the guide catheter (GC) are key factors for safely performing RA.

Regional cerebral blood flow in a patient with asystole episodes associated with anti-NMDA receptor encephalitis.

Anti-N-methyl-D-aspartate (NMDA) receptor encephalitis is a rare and severe autoimmune encephalitis that displays neuropsychiatric symptoms and autonomic instability, e.g., hypoventilation and cardiac arrhythmia.

One-Year Outcome of Drug-Coated Balloon vs. Drug-Eluting Stent in Patients Undergoing Initial Percutaneous Coronary Intervention (PCI) for De Novo Lesion.

Background: Drug-eluting stents (DES) are the major treatment option in percutaneous coronary intervention (PCI). Recently, drug-coated balloon (DCB) utilization has been increasing globally, leading to the expected new strategy of "stent-less PCI." This study aimed to evaluate the one-year outcome of DCB compared to DES.

Clinical evaluation of bone quality of particulate cancellous bone and marrow, and implant prosthetic rehabilitation.

This study aimed to subjectively evaluate bone quality in the particulate cancellous bone and marrow (PCBM) graft area and to assess the survival rates of implants. A retrospective review was conducted based on patient age, sex, diagnosis, reconstructed site, number of implants, prosthetic type, and duration of follow-up. Images from computed tomography (CT) before implant insertion were obtained and used in this study.

[A case of Hashimoto's encephalopathy with acute onset of psychiatric symptoms and diffuse deep white matter lesions on brain MRI].

A 51-year-old man developed acute disturbances in consciousness and psychiatric symptoms one month prior to admission. He was referred and admitted to the Department of Psychiatry of our hospital and transferred to the neurology department because diffuse white matter lesions were found on his brain during MRI. I-IMP-SPECT showed extensive cerebral hypoperfusion mainly in the frontal lobes.

Case report: A case of anti-recoverin antibody-positive encephalitis exhibiting Cotard and Capgras delusions that was successfully treated with electroconvulsive therapy.

Recoverin is a neuron-specific calcium-binding protein that is mainly located in the retina and pineal gland. Few reports have described patients with anti-recoverin antibody-positive encephalitis, and no cases of psychosis associated with this encephalitis have been reported. We report a patient with anti-recoverin antibody-positive encephalitis with Cotard and Capgras delusions who was successfully treated with electroconvulsive therapy (ECT).

Clinical presentation and antimicrobial resistance of invasive Escherichia coli disease in hospitalized older adults: a prospective multinational observational study.

Background: Clinical data characterizing invasive Escherichia coli disease (IED) are limited. We assessed the clinical presentation of IED and antimicrobial resistance (AMR) patterns of causative E. coli isolates in older adults.

A Case of Legionella pneumophila Serogroup 13 Pneumonia Based on the Detection of Serogroup-Specific Genes in Culture-Negative Sputum.

Legionella pneumophila serogroup (SG) 1, the main cause of Legionnaires' disease, can be diagnosed using urinary antigen testing kits. However, lower respiratory tract specimen cultures are required to identify L. pneumophila SG 2-15.

Symptomatic periesophageal vagal nerve injury by different energy sources during atrial fibrillation ablation.

Background: Symptomatic gastric hypomotility (SGH) is a rare but major complication of atrial fibrillation (AF) ablation, but data on this are scarce.

Objective: We compared the clinical course of SGH occurring with different energy sources.

Methods: This multicenter study retrospectively collected the characteristics and clinical outcomes of patients with SGH after AF ablation.

Measures of oral health-related quality of life in patients with bone graft and implant prosthetic rehabilitation at the anterior of mandible/maxilla among young and middle-aged adults: a retrospective pilot study.

Objectives: Dental implants are believed to contribute to improved masticatory function and oral health-related quality of life (OHRQOL), but the details remain unclear. The aim of this study was to evaluate the clinical outcomes of dental implant prosthetic rehabilitation after bone graft at the anterior mandible/maxilla based on OHRQOL, particularly in young and middle-aged patients.

Methods: This retrospective study included 11 patients who received bone grafts at the anterior mandible/maxilla and dental implant surgery.

Analgesic effect of a lidocaine-ropivacaine mixture for extraction of impacted mandibular third molars: a randomized controlled trial.
