The state of radiographic technique in the examination of the colon: a survey in 1987

R F Thoeni, A R Margulis


Results of an extensive multiple-choice questionnaire sent to 175 leading medical centers in the world were analyzed and compared with those of a similar survey from 1976. One hundred sixty-two (93%) responses were received. Both single- and double-contrast enema procedures are still employed, but the use of the double-contrast technique has markedly increased. Preparation of the colon is even more meticulous than in 1976 and is equal for both techniques. Pharmacologic aids are used more often but preparatory enemas less frequently than in 1976. The use of fluoroscopic equipment has not significantly changed. The decision on the appropriate sequence for the barium enema examination and colonoscopy is based on the individual clinical problem in the majority of cases, and the time interval between the barium enema examination and lower endoscopy with or without biopsy is significantly shorter than in 1976. The use of computed tomography and magnetic resonance imaging has increased since 1976, but angiography is used less often and mostly for unknown causes of bleeding and to stop bleeding.

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.

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.

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.
