Abstract

The purpose of the present study was to evaluate the accuracy of endoscopic ultrasonography (EUS) with a curved-array transducer and to determine the value of endosonography-guided biopsy. EUS was performed in 162 consecutive patients for preoperative staging of gastric or esophageal cancer (n = 122) or for EUS-guided biopsy (n = 40). All patients were examined using a flexible echoendoscope (Pentax FG32-UA) equipped with a 7.5-MHz curved-array transducer. A specially designed fine needle was used for EUS-guided biopsy of submucosal or extrinsic lesions. Surgery was performed in 19 of 48 patients with esophageal cancer and 60 of 74 patients with gastric cancer. The accuracy in the assessment of the infiltration depth of esophageal cancer and in the determination of lymph node involvement was 84% and 88%, respectively. In gastric cancer the tumor infiltration depth was assessed correctly in only 65% of the patients. The identification of early gastric cancer proved to be a major problem. The accuracy in the detection of lymph node involvement was 73%. Obstructing tumors were examined in 17 patients with carcinoma of the esophagus or the gastric cardia. The accuracy of EUS in determining the T-stage and the N-stage of stenotic tu...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
