Abstract

Urinary incontinence is a condition with involuntary escape of urine and causes not only medical but also social and hygienic problems. One of the causes of incontinence is insufficiency of the urethral closure mechanism which in men is usually caused by previous prostatectomy or neurogenic dysfunction of the lower urinary pathways. The method of choice is the application of an artificial sphincter (model AMS 800) to the bulbar urethra or cervix. The authors applied an artificial sphincter in 1993-1996 to one boy and 14 men aged 11-72 years. The basic components of the artificial sphincter of the urethra-AMS 800 is a cuff, balloon and pump. The whole system is filled with isotonic solution Omnipaque 300, the cuff which is 45-80 mm long is placed either round the bulbar urethra from a perineal approach or round the cervix by a retropubic approach. The pump is placed beneath the skin of the scrotum and the balloon is in a perivesical position. All parts of the AMS are connected by tubes. Because of infectious complications the authors had to explant the sphincter in two patients. In one patient it was necessary to add another cuff. The perineal approach is simpler, but is associated with a higher risk of erosion of the urethra. P...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.
