Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Cleaning, Sterilization, and Disinfection

Cleaning, Sterilization, and Disinfection

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Methods of Sterilization I: Physical Methods

Methods of Sterilization I: Physical Methods

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

Methods of Sterilization II: Chemical Methods

Methods of Sterilization II: Chemical Methods

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Inhibitors of Bacterial DNA Synthesis

Inhibitors of Bacterial DNA Synthesis

Bacterial pathogens depend on precise and efficient DNA replication to sustain infection. Two type II topoisomerases—DNA gyrase and topoisomerase IV—are critical to this process, as they resolve DNA supercoiling and unlink chromosomes during replication. Fluoroquinolones, synthetic derivatives of quinolones, exploit this mechanism by stabilizing the transient DNA–enzyme cleavage complex, preventing strand religation, and causing lethal double-strand breaks. These antibiotics are selectively...

Summary

Quinacrine sterilization (QS) offered a nonsurgical permanent contraception method. Despite early concerns about carcinogenicity, extensive studies show no increased cancer risk, suggesting potential for this method.

Area of Science:

Reproductive health
Contraception development
Medical device innovation

Background:

Nonsurgical permanent contraception methods are sought for wider accessibility.
Quinacrine's known effect of inducing fibrous adhesions in the pleural cavity inspired its investigation for tubal occlusion.

Observation:

Instillation of quinacrine into the uterine cavity was hypothesized to cause tubal scarring and permanent blockage.
A modified Copper T intrauterine device inserter was developed for precise delivery of quinacrine pellets.

Findings:

Quinacrine sterilization (QS) was introduced and utilized in several countries, with a large trial in Vietnam.
Concerns regarding quinacrine's potential carcinogenicity led to its discontinuation in 1993.
Subsequent epidemiological data from extensive human studies have not supported an increased cancer risk associated with quinacrine.

Implications:

Re-evaluation of quinacrine sterilization is warranted given the lack of evidence for increased cancer risk.
QS could offer a viable, reversible, or permanent nonsurgical contraception option.
Further research into quinacrine's safety and efficacy profile is needed for potential future clinical application.
