Disorders of the Male Reproductive System01:20

Disorders of the Male Reproductive System

2.6K
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

Male Sexual Response: Erection & Ejaculation01:17

Male Sexual Response: Erection & Ejaculation

7.2K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors

278
Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

Electroconvulsive Therapy01:30

Electroconvulsive Therapy

266
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Summary

Low-intensity extracorporeal shock wave therapy (Li-ESWT) shows promise for erectile dysfunction. However, current research limitations necessitate its use only in clinical trials until further evidence is available.

Area of Science:

  • Urology
  • Regenerative Medicine
  • Biomedical Engineering

Background:

  • Energy-based therapies offer novel approaches for erectile dysfunction (ED).
  • Low-intensity extracorporeal shock wave therapy (Li-ESWT) is a leading energy-based treatment with demonstrated efficacy and safety.
  • Existing evidence primarily focuses on phosphodiesterase-5 inhibitor responders.

Purpose of the Study:

  • To evaluate the efficacy and safety of Li-ESWT for erectile dysfunction.
  • To identify limitations in current randomized controlled trials (RCTs) for Li-ESWT.
  • To determine the appropriate clinical application of Li-ESWT based on existing evidence.

Main Methods:

  • Review of randomized controlled trials (RCTs) investigating Li-ESWT for ED.
  • Analysis of study populations, treatment protocols, and follow-up durations.
  • Assessment of evidence quality and generalizability.

Main Results:

  • RCTs for Li-ESWT in ED often have short follow-up periods.
  • Inconsistent treatment protocols and small sample sizes are common limitations.
  • The majority of studies focus on patients who respond to phosphodiesterase-5 inhibitors.

Conclusions:

  • Current evidence for Li-ESWT in erectile dysfunction is limited by methodological constraints.
  • Broader patient populations and longer follow-up durations are needed.
  • Li-ESWT should currently be restricted to Institutional Review Board (IRB)-approved clinical research.
