Does vibration offer any advantage over visual stimulation studies (VSS) in the assessment of erectile capacity?

Abstract

The purpose of this work was to determine whether vibration stimulation or erotic videotape material can provide an acceptable diagnostic yield for patients with erectile dysfunction (ED) without the patient needing to endure more explicit erotic films, which may be distasteful to some patients, or intracavernous injections, to which there may be a high inhibitory response. Ninety-five subjects were randomly exposed to either vibration or videotape alone and erectile response monitored by the RigiScan. Where no clinical response was recorded by the RigiScan or by self-report by the patient, both stimuli were presented to the subject. Forty-nine subjects received vibration first and 46 received videotape first. Use of clinically based standardised measures revealed neither group achieving above threshold responses to the first stimulation and there were no differences between the two groups. Eight subjects (8%) between both groups exceeded the tip threshold during combination stimulation. Single stimulation with vibration or erotic videotape with provocative RigiScan monitoring is unhelpful in the assessment of ED in any of the diagnostic subgroups of ED. In comparison to previous provocative studies, combination of stimuli sets...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.
