Background: Patients with esophageal squamous cell carcinoma (ESCC) frequently develop synchronous head and neck squamous cell carcinoma (HNSCC). With advances in endoscopic technology and widespread screening of synchronous cancers, the detection of synchronous HNSCC and superficial ESCC (SESCC) is increasing. We aimed to evaluate the impact of preceding HNSCC treatment on synchronous SESCC.

Background: Aggressive lipid-lowering therapy is important for secondary prevention of acute myocardial infarction (AMI). The recommended target for low-density lipoprotein cholesterol (LDL-C) of <70 mg/dL is often not achieved. To address this gap, we implemented a clinical pathway in all hospitals that perform percutaneous coronary interventions (PCI) with primary care physicians in Nagasaki and aimed to validate the effectiveness of this pathway in an acute setting.

Methods: A total of 220 patients who underwent gastric or colorectal endoscopic submucosal dissections in two institutions between January 2022 and October 2023 were included. Significant factors related to cloudiness were determined using univariate and multivariate analyses.
With the expansion of indications of flow diverter (FD) for cerebral aneurysms, FD placement for posterior communicating artery (Pcom) aneurysms has been approved. However, it is controversial whether Pcom aneurysms should be treated with FD or not. In this study, we report the outcome of FD treatment for Pcom aneurysms in Japan.

The expression of 11 developmentally important genes in individual bovine in vivo-derived (IVD) and IVF embryos were examined. Gene expression profiling was conducted by classifying the expression level of each gene in individual embryos as low, medium, or high.

When wild-type and fusions were stably expressed in the human glioma cell lines A172 and U343MG, immunoblotting revealed that fusion specifically activated the JAK2-STAT3 pathway, a major RTK downstream signaling pathway, when compared with wild-type . Immunoprecipitation of the fractionated cell lysates revealed a more abundant association of the KLC1-ROS1 fusion with JAK2 than that observed for wild-type ROS1 in the cytosolic fraction.

This study aimed to elucidate the characteristics of CRP and the prognostic factors in patients who were administered with atezolizumab plus bevacizumab (ATZ + BEV) for unresectable hepatocellular carcinoma (HCC).
Methods: A total of 213 patients who received ATZ + BEV for HCC from November 2020 to March 2023 at 15 hospitals were enrolled in this retrospective study.

Objective: The association between the severity of COVID-19 and gastrointestinal (GI) bleeding is unknown. This study aimed to determine whether the severity of COVID-19 is a risk factor for GI bleeding.
Design: A multicentre, retrospective cohort study was conducted on hospitalised patients with COVID-19 between January 2020 and December 2021.
Purpose: Recently, a novel device, the Woven Endo Bridge (WEB), was developed for wide-neck bifurcation intracranial aneurysms (WNBAs). The aim of this study is to investigate factors that contribute to adequate occlusion (AO) after the operation using detailed radiological images.
Methods: The subjects were 29 patients with 29 aneurysms who received WEB implantation for WNBAs between December 2020 and April 2022.
Coronary periarteritis with aneurysms has been reported as a cardiovascular manifestation of immunoglobulin G4 (IgG4) -related disease. We report a 10-year clinical observation of a patient with IgG4-related coronary periarteritis (IgG4-rCP) characterized by multiple thickening of periarterial tissue and coronary artery aneurysms (CAAs).A 60-year-old man with a history of IgG4-related autoimmune pancreatitis had an incidental detection of a total of 5 tumor-like lesions surrounding the right and left coronary arteries on coronary computed tomography angiography (CCTA) in 2012.

To date, there have been no reports of treatment outcomes specific to intradural internal carotid artery (ICA) aneurysms. The safety and efficacy of the PED treatments for intradural ICA aneurysms are reported.

We analyzed 163 participants who underwent both coronary and chest CT examinations at six centers within 3 months. Agatston scores were calculated on standard ECG-gated scans and classified as none (0), mild (1-99), moderate (100-400), or severe (>400).

Thickened fluids are widely used to prevent aspiration in patients with dysphagia; however, there is little evidence that they can prevent AP. This study aimed to clarify the differences between restriction of oral intake of fluids (R), only thickened fluids (TF), and no restriction of fluids (NR) for AP in patients with dysphagia after HNC treatment.

Methods: We prospectively evaluated the rate of lymph node metastasis in Levels IIB and V in head and neck cancer patients who underwent neck dissection at eight centres in Japan. In addition, post-operative arm abduction disability was classified according to functional assessment values at 1 month post-operatively, and the rate of maintained function at 6 and 12 months was evaluated.
Background: In head and neck surgery cases where skin is severely scarred or adhered to surrounding tissue, reconstruction can be difficult to perform using microsurgical tissue or conventional pedicled pectoralis major myocutaneous flap (PMMF) transfer given the risks, which include damage to major vessels when manipulating scarred skin. For such cases, we perform a 2-stage external PMMF transfer, whereby the PMMF is directly sutured to the defect over the neck skin (without manipulation the hardened skin), and the flap division is then performed secondarily.
Methods: A total of 30 patients who had histories of radiotherapy (60-70 Gy) and prior neck dissection received the 2-stage external PMMF transfer procedure.
Background: Brenner tumor is a rare epithelial ovarian neoplasm that accounts for 2-3% of all ovarian neoplasms. Herein, we report the first case of thoracic spinal metastasis of recurrent Brenner tumor without local recurrence.Case Description.
