Abstract

Transurethral radiofrequency thermotherapy was performed in 38 patients with benign prostatic hyperplasia using Thermex II (Direx) between December 1992 and June 1993, and its clinical efficacy was evaluated by analysing the subjective and objective responses following the treatment. Each patient was treated with an indwelling 16 Fr balloon catheter with electrode, in a single session of 90 minutes at 47-47.5 degrees C. The clinical efficiency was evaluated by total of AUA symptom score and objective findings in terms of maximum flow rate 12 weeks after treatment. The symptom score improved from 15.4 +/- 4.9 (mean +/- SD) to 7.3 +/- 5.2 25% or more improvement was found in 80% (20/25) of patients. No significant change was found in average of maximum flow rate before and after treatment, which were 8.9 +/- 4.1 (ml/sec) and 9.2 +/- 3.3, respectively. During the treatment no severe adverse effect except sense of heat and urgency was detected. Posttreatment urinary retension was found in 9 patients and catheters were indwelled in eight of them for a few days and prostatectomy was performed in one patients after 8 weeks of treatment. In four patients prostatectomy was performed between one day and 8 weeks after thermotherapy and hi...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.
