Acute Liver Failure Caused by Isoniazid during Preventive Treatment for Latent Tuberculosis: A Rare Autopsy Case Report.

Treating patients with latent tuberculosis infection (LTBI) to prevent the development of tuberculosis is a fundamental treatment strategy in daily practice. Isoniazid (INH) therapy for 6-12 months is recommended. However, INH can also cause hepatotoxicity.

Combination of a Topical Anti-Inflammatory Drug and a Moisturizer, Both with a Lamellar Structure Containing Synthetic Pseudo-Ceramides, for the Treatment of Patients with Mild-to-Moderate Atopic Dermatitis.

Purpose: Atopic dermatitis is characterized by chronic inflammation and dryness accompanied by severe itching. The combined use of moisturizers and topical anti-inflammatory drugs is essential for alleviating atopic dermatitis. We have developed a topical anti-inflammatory drug with a steroid and a moisturizer with heparinoid, both in lamellar structure-based formulations containing synthetic pseudo-ceramides.

Pathological complete response of hepatocellular carcinoma confirmed by conversion hepatectomy following atezolizumab plus bevacizumab therapy: a case report and literature review.

The combination regimen of atezolizumab plus bevacizumab (Atezo/Bev) is currently used as first-line treatment in patients with unresectable hepatocellular carcinoma. Herein, we report a rare case of curative hepatic resection performed as conversion surgery in a patient with intermediate-stage hepatocellular carcinoma following preoperative Atezo/Bev therapy. After five treatment cycles of Atezo/Bev therapy, followed by four cycles of atezolizumab monotherapy, the tumor marker levels decreased to baseline levels and 22 small daughter nodules disappeared, leaving only the primary tumor.

The Risk of Bleeding in Small/Straight Esophageal Varices with Red Color Sign on Endoscopy: A Retrospective Analysis from the Natural Course.

Red color sign-positive (RC-positive) esophageal varices present a high bleeding risk, necessitating prophylactic treatment. Among RC-positive esophageal varices, those classified morphologically as small straight varices (Form level 1: F1) are difficult to treat. Moreover, the appropriate time for therapeutic intervention remains undefined.

Efficacy of Pseudo-Ceramide-Containing Steroid Lamellar Cream in Patients with Mild to Moderate Atopic Dermatitis: A Randomized, Double-Blind Study.

Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin disorder involving decreased barrier function of the stratum corneum. This decrease, caused by a reduction in ceramide, the primary component of intercellular lipids in the stratum corneum, leads to a disturbance in the lamellar structure.

Methods: We developed a formulation (test cream) containing a steroid and synthetic pseudo-ceramide (SLE: N-(3-hexadecyloxy-2-hydroxypropyl)-N-2-hydroxyethyl hexadecanamide) that forms a lamellar structure on the skin after its application and drying.

Measuring optimal ultrasound speed using endoscopic ultrasound in patients with chronic pancreatitis, including early stage.

Objectives: Ultrasound speed (USS) correction improves image quality by estimating the optimal USS correcting the deviation from a predetermined USS. This study assessed USS differences between chronic pancreatitis (CP), early CP (ECP), and normal pancreas when using endoscopic ultrasound (EUS). The usefulness of measuring optimal USS was evaluated for patients with CP, including early stage patients.

Salvage Endoscopic Submucosal Dissection for Local Recurrence of Superficial Esophageal Squamous Cell Cancer after Photodynamic Therapy.

Photodynamic therapy is useful as organ-preservation salvage therapy for residual recurrence of esophageal squamous cell carcinoma after chemoradiation therapy. However, the high residual recurrence rate of photodynamic therapy poses a problem. We herein report a patient who underwent photodynamic therapy for recurrence of superficial esophageal squamous cell carcinoma after chemoradiation therapy.

Efficacy of Heparinoid Cream Containing Pseudo-Ceramide for Remission of Atopic Dermatitis.

Purpose: Atopic dermatitis (AD) is characterized by chronic inflammation, which frequently recurs, is exacerbated, and enters remission. A maintenance remission period is important for AD patients. We developed a formulation for use during AD remission, containing heparinoid and pseudo-ceramide that forms a lamellar structure.

Analysis of Endoscopic Evaluation Reliability for Ulcerative Colitis in Histological Remission.

The Mayo endoscopic subscore (MES) is a major endoscopic scoring system used to assign a status of mucosal inflammation and disease activity to patients with ulcerative colitis (UC). Using interobserver reliability (IOR), this study clarified the difficulties for endoscopic observers imposed by MES parameters used for the endoscopic evaluation of UC in histological remission. First, 42 endoscopists of four observer groups examined each MES parameter, which were evaluated from endoscopically obtained images of 100 cases as Grade 0 or 1 of the Nancy histological index of histopathological inflammation.

Whole circumferential endoscopic submucosal dissection of superficial adenocarcinoma in long-segment Barrett's esophagus: A case report.

Background: Esophageal adenocarcinoma (EAC) derived from long-segment Barrett's esophagus (LSBE) is extremely rare in Asia. LSBE-related EAC is often difficult to diagnose in the horizontal extent. If the tumor has spread throughout the LSBE, whole circumferential endoscopic submucosal dissection (ESD) should be performed, which is difficult to complete safely.

Recent Advances in Endosonography-Elastography: Literature Review.

Ultrasonographic elastography is a modality used to visualize the elastic properties of tissues. Technological advances in ultrasound equipment have supported the evaluation of elastography (EG) in endosonography (EUS). Currently, the usefulness of not only EUS-strain elastography (EUS-SE) but also EUS-shear wave elastography (EUS-SWE) has been reported.

Association of long-term endoscopic biliary stent placement with choledocholithiasis: a literature review.

Endoscopic stone removal is currently the first-line procedure for the treatment of common bile duct stones. Advances in equipment and treatment techniques have expanded the scope of application of endoscopic treatment to include stones that have previously been difficult to remove endoscopically, such as stacked stones and large stones. For the treatment of common bile duct stones in elderly patients in particular, long-term placement of a biliary stent is increasingly being selected.

Refractory Immune Checkpoint Inhibitor-Induced Colitis Improved by Tacrolimus: A Case Report.

Immune checkpoint inhibitors (ICIs) increase T-cell activity and antitumor immune response. However, they also have immune-related adverse effects that can affect the gastrointestinal (GI) tract. A 62-year-old male patient who had undergone right lung upper lobectomy for adenocarcinoma of the lung received chemotherapy with pemetrexed sodium hydrate, carboplatin, and pembrolizumab to prevent postoperative recurrence of liver metastasis.

Interobserver Reliability of the Endoscopic Ultrasound Criteria for the Diagnosis of Early Chronic Pancreatitis: Comparison between the 2009 and 2019 Japanese Diagnostic Criteria.

In 2009, diagnostic criteria for early chronic pancreatitis (DCECP2009) were proposed by the Japan Pancreas Society. This study aimed to evaluate the interobserver reliability (IOR) of endoscopic ultrasound (EUS) criteria for diagnosis of early chronic pancreatitis (ECP) between DCECP2009 and 2019 diagnostic criteria for ECP (DCECP2019) to assess the validity of the revision from the perspective of EUS findings. Among patients who underwent a detailed observation of the pancreas by EUS at our institution between January 2018 and March 2019, EUS images of 97 patients were extracted.

Factors Affecting Technical Difficulty in Balloon Enteroscopy-Assisted Endoscopic Retrograde Cholangiopancreatography in Patients with Surgically Altered Anatomy.

Success rates of balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) for patients with a reconstructed intestinal tract after surgical procedures are unsatisfactory. We retrospectively investigated the factors associated with unsuccessful BE-ERCP. Ninety-one patients who had a reconstructed intestinal tract after gastrectomy or choledochojejunostomy were enrolled.

Development of biliary stent applying the antibacterial activity of silver: A literature review.

Background: Endoscopic transpapillary stenting is commonly performed in patients with obstructive jaundice caused by a biliary stricture. Although the plastic stent (PS) is widely used for biliary drainage because of the low-cost and easy procedure, patency is short after placement in the bile duct because of the small diameter. Dysfunction of PS is primarily caused by biliary sludge that forms as a result of bacterial adhesion and subsequent biofilm formation on the inner surface of the stent.

Thiopurines: Recent Topics and Their Role in the Treatment of Inflammatory Bowel Diseases.

Ulcerative colitis (UC) and Crohn's disease (CD) are chronic inflammatory bowel diseases (IBD) of unknown etiology, characterized by repeated relapse and remission. The efficacy of thiopurine in IBD was first reported in the late 1960s. Thiopurines are used to alleviate the symptoms of IBD, especially UC.

Feasibility and Safety of Transjugular Liver Biopsy for Japanese Patients with Chronic Liver Diseases.

Background And Study Aim: Transjugular liver biopsy (TJLB) can be used in patients who are ineligible for percutaneous liver biopsy (PLB) with acute and chronic hepatic disease. This study aimed to evaluate the usefulness and safety of TJLB in patients who were not indicated for PLB.

Methods: Between July 2014 and February 2019, a total of 134 patients underwent liver biopsies at our institution.

The Role of Endoscopic Ultrasound for Esophageal Varices.

Esophageal varices are caused by the development of collateral circulation in the esophagus as a result of portal hypertension. It is important to administer appropriate preventive treatment because bleeding varices can be fatal. Esophageal varices have complex and diverse hemodynamics, and there are various variations for each case.

Interobserver Reliability of Endoscopic Ultrasonography: Literature Review.

Endoscopic ultrasonography (EUS) has been applied to the diagnosis of various digestive disorders. Although it has been widely accepted and its diagnostic value is high, the dependence of EUS diagnosis on image interpretation done by the endosonographer has persisted as an important difficulty. Consequently, high interobserver reliability (IOR) in EUS diagnosis is important to demonstrate the reliability of EUS diagnosis.

A Case of Lung Abscess Caused by Double Immunosuppressive Therapy to Treat Ulcerative Colitis.

A 25-year-old man was admitted to our institution for remission induction therapy to treat a 12-year condition of ulcerative colitis (UC). Previously, he was treated with drugs, such as mesalamine, immunomodulators, prednisolone (PSL), and anti-TNFα anti-body, but remission was not maintained. Therefore, we started remission induction therapy with 20 mg/day of tofacitinib (TOF) to inhibit the action of Janus kinase.
