Hypertensive urogram: a nondiscriminatory test for renovascular hypertension

AJR. American Journal of Roentgenology

Abstract

Evidence has accumulated from clinical experience that the hypertensive urogram is not a satisfactory screening test for differentiating hypertension due to renal artery stenosis from essential hypertension. This is contrary to the conclusion reached in the report of the Cooperative Study published in 1972. The present investigation was done to: (1) reassess the value of the hypertensive urogram on the basis of experience at a single institution and (2) to reassess the validity of the Cooperative Study conclusions. In 197 patients operated on at the University of Michigan for renal artery stenosis during 1961-1977, the true-positive rate for hypertensive urography for prediction of surgical cure or improvement was 60.2%. In 131 patients undergoing hypertensive urography in 1977, the incidence of positive examinations in screening was 0.8%. The chance for a favorable surgical outcome in hypertensive patients having positive hypertensive urograms is now calculated as 24%, rather than 50% as stated in the Cooperative Study. Reanalysis of the Cooperative Study data also shows that the false-negative rate for screening is at least 21.8%, rather than 1.7%. A screening strategy fo choosing patients for renal arteriography and surgery ...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.
