Abstract

Most of the urodynamic studies are conducted in the laboratory during a brief recording time and under nonphysiological conditions and, thus, may fail to unfold the nature of existing pathological conditions of the lower urinary tract; false positives and false negatives are possible. To overcome some of the difficulties associated with conventional P/F studies we have developed, with the cooperation of Medical Measurement System company, Entschede, The Netherlands, a portable system (UDS 2000) for ambulatory monitoring of intravesical pressure, abdominal pressure and EMG connectable with a weight-transducer flowmeter that allows to perform Holter P/F measurements. We compared the results obtained with conventional P/F studies and with Holter P/F studies in 58 BPH patients. During the filling phase we observed a slightly increased number of stable detrusors with Holter P/F recording (46 vs 42); conversely, the number of patients suffering from urge incontinence was the same (7 pts). During the voiding phase, out of 45 patients considered obstructed at conventional P/F study, only 42 were really urodynamically obstructed (93.3%), while other 3 patients had bordeline obstruction. 4 patients with bordeline obstruction at conventio...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.
