Psychological rehabilitation for isolated patients with COVID-19 infection: A randomized controlled study.

Objective: To improve the mental health of isolated patients with COVID-19 by face-to-face psychological rehabilitation program.

Design: Randomized controlled study.

Setting: Single community-based hospital.

Modified FOLFOX-4 as first-line and salvage treatment in advanced gastric cancer.

Background/aims: Oxaliplatin, leucovorin and fluorouracil combination therapy (FOLFOX) was effective and safe treatment in AGC. The aim of this study was to evaluate the efficacy and safety of the modified FOLFOX-4 using low dose leucovorin for patients with advanced gastric cancer and analyze the efficacy of this regimen as first-line and salvage treatment.

Methodology: Forty-two patients with recurrent or metastatic gastric cancer received oxaliplatin 85 mg/m2 and leucovorin 20 mg/m2 followed by 5-FU bolus 400 mg/m2 and then 5-FU 600 mg/m2 every 2 weeks.

Risk factors for immediate and delayed bleeding associated with endoscopic submucosal dissection of gastric neoplastic lesions.

OBJECTIVE. Endoscopic submucosal dissection (ESD) of gastric neoplasia has been reported to have a higher bleeding rate than conventional endoscopic mucosal resection (EMR). The aim of this study was to identify the risk factors for bleeding associated with ESD.

[A case of primary sigmoid colon mucosa-associated lymphoid tissue lymphoma].

The gastrointestinal (GI) tract is the most frequently involved site of mucosa-associated lymphoid tissue (MALT) lymphoma. Stomach is the most common site of involvement among the GI tract. However, MALT lymphoma of the large intestine is rare.

[A case of autoimmune pancreatitis combined with extensive involvement of biliary tract].

Autoimmune pancreatitis is a distinct disease characterized by the presence of autoantibodies and hypergammaglobulinemia, inflammation of the pancreatic parenchyma, and irregular stricture of the pancreatic duct. The involvement of distal common bile duct is frequently observed, but intrahepatic bile duct involvement is very rare, which seem to have similar feature to primary sclerosing cholangitis. We report a case of the patient with autoimmune pancreatitis combined with extensive involvement of extrahepatic and intrahepatic bile duct, which had a favorable response to steroid therapy.

Imaging findings of hepatic paragonimiasis : a case report.

Hepatic paragonimiasis is a rare form of ectopic infestation caused by Paragonimus. We experienced a case of hepatic paragonimiasis that showed characteristic imaging findings. CT and MR images showed a cluster of small cysts with rim enhancement in the subcapsular area of the liver.

Focal hepatic lesions: contrast-enhancement patterns at pulse-inversion harmonic US using a microbubble contrast agent.

Objective: To analyze the contrast-enhancement patterns obtained at pulse-inversion harmonic imaging (PIHI) of focal hepatic lesions, and to thus determine tumor vascularity and the acoustic emission effect.

Materials And Methods: We reviewed pulse-inversion images in 90 consecutive patients with focal hepatic lesions, namely hepatocellular carcinoma (HCC) (n=43), metastases (n=30), and hemangioma (n=17). Vascular and delayed phase images were obtained immediately and five minutes following the injection of a microbubble contrast agent.

Imaging with 99mTc ECDG targeted at the multifunctional glucose transport system: feasibility study with rodents.

Purpose: To evaluate the feasibility of technetium 99m ((99m)Tc) ethylenedicysteine-deoxyglucose (ECDG) imaging in tumor-bearing rodents.

Materials And Methods: ECDG was synthesized by means of reacting ethylenedicysteine with glucosamine, with carbodiimide as the coupling agent. Hexokinase assays were performed at an ultraviolet wavelength of 340 nm.

MR evaluation of the "arcuate" sign of posterolateral knee instability.

Objective: The purpose of this study was to evaluate associated knee injuries using MR imaging in patients with the "arcuate" sign, a term referring to avulsion fracture of the proximal fibula on conventional radiographs.

Material And Methods: MR imaging of 18 cases (17 patients, both knees in one patient) with the arcuate sign on conventional radiographs was retrospectively interpreted to evaluate the associated meniscal, ligamentous, and bony injuries. In 12 cases, MR findings were correlated with surgical results.
