Subclavian artery pseudoaneurysm in vascular Behcet's disease repaired using endovascular treatment: A case report of the clinical course over 10 years.

The vascular involvement in patients with Behcet's disease is defined as vascular Behcet's disease, which can greatly influence the prognosis. However, there are few reports on endovascular treatment (EVT) for subclavian pseudoaneurysms with long-term prognosis over 10 years. We present the case of a 42-year-old man with left subclavian artery pseudoaneurysm due to vascular Behcet's disease who was treated with EVT along with immunosuppressive therapies.

MRI characteristics of syringomyelia associated with foramen magnum arachnoiditis: differentiation from Chiari malformation.

Background: It is important to distinguish foramen magnum arachnoiditis (FMA) from Chiari malformation (CM) before surgery because the operative strategies for these diseases differ. In the current study, we compared pretreatment magnetic resonance imaging (MRI) of FMA with CM and investigated the MRI findings useful to differentiate between these diseases.

Methods: We retrospectively reviewed patients with FMA or CM aged ≥ 18 years who underwent surgeries at our institution between 2007 and 2019.

Recurrence of gastric cancer caused by implantation of tumor cells after curative endoscopic submucosal dissection.

A 93-year-old female underwent curative endoscopic submucosal dissection (ESD) for intramucosal gastric cancer (70 mm in diameter) in the antrum. The lesion showed an irregularly villous structure covered with mucus. En bloc resection was performed.

Introduction of histological classification and cytology reporting format of the Japanese General Rules for the Description of Thyroid Cancer with a special focus on the differences of the WHO Histological Classification and The Bethesda System of Thyroid Cytology.

Histological classification and cytology reporting format described in General Rules for the Description of Thyroid Cancer, the 8 edition (2019) (the Japanese General Rules) were briefly introduced. Moreover, the differences between "the Japanese General Rules", and WHO Histological Classification, the 4 edition (2017) and The Bethesda System for Reporting Thyroid Cytopathology, the 2 edition (2018) were also explained. The Japanese General Rules did not accept the borderline lesions of thyroid tumor which were newly shown in WHO Histological Classification.

Endovascular treatment of acute basilar artery occlusion: Outcomes, influencing factors and imaging characteristics from the Tama-REgistry of acute thrombectomy (TREAT) study.

Objective: The effectiveness of mechanical thrombectomy (MT) for acute basilar artery occlusion (ABAO) remains unknown. We evaluated the feasibility, safety, and efficacy of endovascular treatment for ABAO.

Methods: We retrospectively investigated patients with ABAO who underwent MT using modern stent retrievers and an aspiration device between January 2015 and March 2019 at 12 comprehensive stroke centers.

Prognosis of hemodialysis patients undergoing surgery for gastric cancer: Results of a multicenter retrospective study.

Background: Little is known about the survival outcomes of and predictive factors for survival in hemodialysis patients undergoing surgery for gastric cancer.

Methods: We performed a multicenter retrospective study from 9 institutions to investigate the survival outcomes of 75 hemodialysis patients with gastric cancer. Patient characteristics included demographic data, hemodialysis- and gastric cancer-related variables.

Impact of obesity in colorectal endoscopic submucosal dissection: single-center retrospective cohort study.

Background: When performing colorectal endoscopic submucosal dissection (ESD) in obese patients, technically difficult cases are sometimes experienced because of difficulty with the insertion of the colonoscope, poor scope maneuverability, or an abundance of fat tissue in the submucosal layer. Since the association between obesity and colorectal ESD has not been investigated, we evaluated the clinical impact of obesity in patients who underwent colorectal ESD.

Methods: We retrospectively reviewed 535 patients who underwent colorectal ESD between April 2012 and February 2019.

Palisade technique as an effective endoscopic submucosal dissection tool for large colorectal tumors.

Endoscopic submucosal dissection (ESD) has become the standard treatment for colorectal ESD, but large colorectal tumors remain difficult to remove. We developed a new method, called the palisade technique, by modifying the multiple tunneling technique. In this method, a palisade of submucosal tissue is left beneath the tumor to anchor a dissected specimen, maintaining effective submucosal traction.

Efficacy of sedation with dexmedetomidine plus propofol during esophageal endoscopic submucosal dissection.

Background And Aim: During endoscopic submucosal dissection for superficial esophageal cancer, patient body movement can sometimes occur, which may cause discontinuation of the procedure. Propofol and dexmedetomidine have recently been found to be useful sedatives for endoscopic submucosal dissection. This study investigated whether sedation using propofol plus dexmedetomidine can suppress the patient's body movements during esophageal endoscopic submucosal dissection and compared this combination with sedation using propofol alone.

Severity by National Institute of Health Stroke Scale Score and Clinical Features of Stroke Patients with Patent Foramen Ovale Stroke and Atrial Fibrillation.

The comparative severity of patent foramen ovale (PFO)-related stroke in patients without atrial fibrillation (AF) and AF-related stroke in patients without PFO is unknown. Therefore, we compared the severity of PFO-related stroke and AF-related stroke. Twenty-six patients who underwent transesophageal echocardiography (TEE) were diagnosed with cardioembolic stroke from July 2018 to March 2020.

Impaired tumor immune response in metastatic tumors is a selective pressure for neutral evolution in CRC cases.

A Darwinian evolutionary shift occurs early in the neutral evolution of advanced colorectal carcinoma (CRC), and copy number aberrations (CNA) are essential in the transition from adenoma to carcinoma. In light of this primary evolution, we investigated the evolutionary principles of the genome that foster postoperative recurrence of CRC. CNA and neoantigens (NAG) were compared between early primary tumors with recurrence (CRCR) and early primary tumors without recurrence (precancerous and early; PCRC).

Spontaneous bladder rupture due to bladder carcinoma: A case report required emergency radical cystectomy.

We report a case of spontaneous bladder rupture due to bladder carcinoma. A 52-year-old female presented in septic shock, and computed tomography revealed free air in the subphrenic space and a mass in the middle of the pelvis. The exploratory laparotomy helped to confirm a definitive diagnosis: bladder rupture due to bladder carcinoma.

Efficacy and safety of colorectal endoscopic submucosal dissection in patients with sarcopenia.

Background: Endoscopic submucosal dissection (ESD) for early-stage colorectal cancer (CRC) has become a common and useful treatment. Although sarcopenia has been identified as an independent risk factor for complications after surgery for CRC, whether sarcopenia is also an independent risk factor for complications after colorectal ESD remains to be clarified. The aim of this study was to compare the outcomes of colorectal ESD in patients with and those without sarcopenia.

Evaluation of colorectal endoscopic submucosal dissection using a multifunctional snare: a prospective clinical feasibility study (with videos).

Background And Aims: The number of colorectal endoscopic submucosal dissections (ESDs) for early colorectal cancer is expected to increase in the future; therefore, cost reduction is a clinically important issue. The SOUTEN snare (Kaneka Medics, Tokyo, Japan) is a novel multifunctional snare developed for hybrid ESD at a low price. If ESD can be performed safely using the SOUTEN snare, the same therapeutic effect can be obtained as with conventional ESD at a lower cost.

The Clinicopathological Results of Thyroid Cancer With BRAFV600E Mutation in the Young Population of Fukushima.

Background: Thyroid ultrasound screening for children aged 0 to 18 years was performed in Fukushima following the accident at the Fukushima Daiichi Nuclear Power Plant. As a result, many thyroid cancer cases were detected. To explore the carcinogenic mechanisms of these cancers, we analyzed their clinicopathological and genetic features.

Cytological examination of the thyroid in children and adolescents after the Fukushima Nuclear Power Plant accident: the Fukushima Health Management Survey.

The Fukushima Daiichi Nuclear Power Plant accident occurred on March 11 2011, following the Great East Japan Earthquake and tsunami. Radioactive materials, including I-131, were released into the environment after the accident. Shortly after, the prefectural government initiated the Fukushima Health Management Survey for monitoring the long-term health conditions of the residents of Fukushima Prefecture.

Retroperitoneal Metastasis, with Marked Fibrosis, of Lung Adenocarcinoma after Afatinib Treatment: An Autopsy Case Report.

A 73-year-old woman was admitted to our hospital for treatment of vomiting. Four months previously, she had been diagnosed with lung adenocarcinoma (cT3N3M1a stage IVA) and started receiving afatinib as first-line treatment. On admission, the primary tumor had shrunk, but abdominal computed tomography revealed a new retroperitoneal lesion causing duodenal obstruction and hydronephrosis.
