Colonic cleansing for radiographic detection of neoplasia: efficacy of the magnesium citrate-castor oil-cleansing enema regimen

To optimize detection of colonic polyps, we instituted a cleansing regimen of dietary restriction, hydration, magnesium citrate, castor oil, and a cleansing enema. We then conducted a review of serially performed barium enemas to determine the percentage of patients with clean colons in a mixed population of 500 inpatients and outpatients in whom this regimen had been used. The same regimen also was used before single- and double-contrast barium enemas were performed in 139 patients with 234 polyps, and radiologic-endoscopic correlation was used to determine the percentage of polypoid neoplasms detected. The review indicated that a clean colon had been achieved in 97% of the 500 cases. In an additional 1.4% of patients, fecal residue was limited to small amounts in the cecum or ascending colon. In only two cases (0.4%) did fecal material prevent an examination that was suitable for detection of large polypoid or circumferential lesions. The single- and double-contrast barium enemas detected 80% and 91%, respectively, of polypoid lesions of all sizes. Single-contrast examinations detected 94% of polyps 10 mm or larger and 72% of polyps 5-9 mm. Double-contrast studies detected 96% of polyps 10 mm or larger and 88% of those 5-9 mm...Continue Reading

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.

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.

Lipidomics & Rhinovirus Infection

Lipidomics can be used to examine the lipid species involved with pathogenic conditions, such as viral associated inflammation. Discovered the latest research on Lipidomics & Rhinovirus Infection.

Spatio-Temporal Regulation of DNA Repair

DNA repair is a complex process regulated by several different classes of enzymes, including ligases, endonucleases, and polymerases. This feed focuses on the spatial and temporal regulation that accompanies DNA damage signaling and repair enzymes and processes.

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.

Torsion Dystonia

Torsion dystonia is a movement disorder characterized by loss of control of voluntary movements appearing as sustained muscle contractions and/or abnormal postures. Here is the latest research.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.
