Comparison of the value of various methods for diagnosis of gastroesophageal reflux

Chirurgisches Forum für experimentelle und klinische Forschung

At the University Surgical Clinic Köln-Lindenthal 5 different methods were employed for assessment of gastro-esophageal reflux between 1975 - 1976 in 283 patients with and without reflux disturbances. Clinically, a gastro-esophageal reflux was found in 72% of the cases. The measurement of intra-esophageal pH with reflux-provocation was the most sensitive, and at the same time the most specific (83, 3%). Significant differentiation betwen patients with and without reflux who had an axial hiatus-hernia could not be made, using x-ray examination and counting of the number of times swallowed in the acid-clearing test. The most suitable procedure in proving the presence of gastro-esophageal reflux was esophagoscopy, intra-esophageal pH-measurement and acid-clearing-and-pH determination, in all of which the results correlated with each other to a high degree.

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. 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.

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
