Tampon Drawing
A tampon is a menstrual product designed to absorb blood and vaginal secretions by insertion into the vagina during menstruation. Unlike a pad, it is placed internally, inside of the vaginal canal. Once inserted correctly, a tampon is held in place by the vagina and expands as it soaks up menstrual blood. However, in addition to menstrual blood, the tampon also absorbs the vagina's natural lubrication and bacteria, which can change the normal pH, increasing the risk of infections from the bacterium ''Staphylococcus aureus'', which can lead to toxic shock syndrome (TSS). TSS is a rare but life-threatening infection that requires immediate medical attention. The majority of tampons sold are made of rayon, or a blend of rayon and cotton, along with synthetic fibers. Some tampons are made out of organic cotton. Tampons are available in several absorbency ratings. Brands include (but are not limited to) Kotex, Playtex, Tampax (Always), O.B., Cora, Lola, Sustain, Honest Company, ...

Hemostasis
In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. This involves coagulation, which changes blood from a liquid to a gel. Intact blood vessels are central to moderating blood's tendency to form clots. The endothelial cells of intact vessels prevent blood clotting with a heparin-like molecule and thrombomodulin, and prevent platelet aggregation with nitric oxide and prostacyclin. When endothelium of a blood vessel is damaged, the endothelial cells stop secretion of coagulation and aggregation inhibitors and instead secrete von Willebrand factor, which initiate the maintenance of hemostasis after injury. Hemostasis involves three major steps: * vasoconstriction * temporary blockage of a hole in a damaged blood vessel by a platelet plug * blood coagulation (formation of fibrin clots) These processes seal the injury or ho ...

Hypotension
Hypotension is low blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. Blood pressure is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the maximum and minimum blood pressures, respectively. A systolic blood pressure of less than 90 millimeters of mercury (mmHg) or diastolic of less than 60 mmHg is generally considered to be hypotension. Different numbers apply to children. However, in practice, blood pressure is considered too low only if noticeable symptoms are present. Symptoms include dizziness or lightheadedness, confusion, feeling tired, weakness, headache, blurred vision, nausea, neck or back pain, an irregular heartbeat or feeling that the heart is skipping beats or fluttering, or fainting. Hypotension is the opposite of hypertension, which is high blood pressure. It is best understood as a physiological st ...

Desquamation
Desquamation occurs when the outermost layer of a tissue, such as the skin, is shed. The term is . Physiologic desquamation Keratinocytes are the predominant cells of the epidermis, the outermost layer of the skin. Living keratinocytes reside in the basal, spinous, or granular layers of the epidermis. The outermost layer of the epidermis is called the Stratum corneum and it is composed of terminally differentiated keratinocytes, the Corneocytes. In the absence of disease, desquamation occurs when corneocytes are individually shed unnoticeably from the surface of the skin. Typically the time it takes for a corneocyte to be formed and then shed is about 14 weeks but this time can vary depending on the anatomical location that the skin is covering. For example, desquamation occurs more slowly at acral (palm and sole) surfaces and more rapidly where the skin is thin, such as the eyelids. Normal desquamation can be visualized by immersing skin in warm or hot water. This induces the out ...

Toxic Shock Syndrome Toxin
Toxic shock syndrome toxin-1 (TSST-1) is a superantigen with a size of 22 kDa produced by 5 to 25% of ''Staphylococcus aureus'' isolates. It causes toxic shock syndrome (TSS) by stimulating the release of large amounts of interleukin-1, interleukin-2 and tumour necrosis factor. In general, the toxin is not produced by bacteria growing in the blood; rather, it is produced at the local site of an infection, and then enters the blood stream. Characteristics Toxic shock syndrome toxin-1 (TSST-1), a prototype superantigen secreted by a ''Staphylococcus aureus'' bacterium strain in susceptible hosts, acts on the vascular system by causing inflammation, fever, and shock. The bacterium strain that produces the TSST-1 can be found in any area of the body, but lives mostly in the vagina of infected women. TSST-1 is a bacterial exotoxin found in patients who have developed toxic shock syndrome (TSS), which can be found in menstruating women or any man or child for that matter. One-third of all ...

Superantigen
Superantigens (SAgs) are a class of antigens that result in excessive activation of the immune system. Specifically it causes non-specific activation of T-cells resulting in polyclonal T cell activation and massive cytokine release. SAgs are produced by some pathogenic viruses and bacteria most likely as a defense mechanism against the immune system. Compared to a normal antigen-induced T-cell response where 0.0001-0.001% of the body's T-cells are activated, these SAgs are capable of activating up to 20% of the body's T-cells. Furthermore, Anti- CD3 and Anti-CD28 antibodies (CD28-SuperMAB) have also shown to be highly potent superantigens (and can activate up to 100% of T cells). The large number of activated T-cells generates a massive immune response which is not specific to any particular epitope on the SAg thus undermining one of the fundamental strengths of the adaptive immune system, that is, its ability to target antigens with high specificity. More importantly, the larg ...

Period Poverty
Menstrual hygiene management (MHM) or menstrual health and hygiene (MHH) refers to access to menstrual hygiene products to absorb or collect the flow of blood during menstruation, privacy to change the materials, and access to facilities to dispose of used menstrual management materials. It can also include the "broader systemic factors that link menstruation with health, well-being, gender equality, education, equity, empowerment, and rights".UNICEF (2019)Guidance on Menstrual Health and Hygiene UNICEF, New York, USA Menstrual hygiene management can be particularly challenging for girls and women in developing countries, where clean water and toilet facilities are often inadequate. Menstrual waste is largely ignored in schools in developing countries, despite it being a significant problem. Menstruation can be a barrier to education for many girls, as a lack of effective sanitary products restricts girls' involvement in educational and social activities. Terminology An accep ...

Condom
A condom is a sheath-shaped barrier device used during sexual intercourse to reduce the probability of pregnancy or a sexually transmitted infection (STI). There are both male and female condoms. With proper use—and use at every act of intercourse—women whose partners use male condoms experience a 2% per-year pregnancy rate. With typical use the rate of pregnancy is 18% per-year. Their use greatly decreases the risk of gonorrhea, chlamydia, trichomoniasis, hepatitis B, and HIV/AIDS. To a lesser extent, they also protect against genital herpes, human papillomavirus (HPV), and syphilis. The male condom is rolled onto an erect penis before intercourse and works by forming a physical barrier which blocks semen from entering the body of a sexual partner. Male condoms are typically made from latex and, less commonly, from polyurethane, polyisoprene, or lamb intestine. Male condoms have the advantages of ease of use, ease of access, and few side effects. Individuals with late ...

Playtex Tampon
Playtex is an American brand name for undergarments, baby products, gloves, feminine hygiene products, and sunscreen. The brand began in 1947 when International Latex Corporation (ILC) created a division named Playtex to produce and sell latex products. Playtex was the first to advertise undergarments on national television in 1955, written by Howard Shavelson at Olgilvie and Mather, and the first to show a woman wearing only a bra from the waist-up in a commercial in 1977. They developed space suits for the Apollo program. Playtex-branded tampons were introduced in the 1960s and became the primary competition to incumbent Tampax. Playtex invented the plastic tampon applicator in 1973. It was one of the tampon manufacturers that were sued for aggressively advertising over-absorbent tampons that led to toxic shock syndrome. Playtex was acquired by Esmark in 1975, and then by Beatrice Foods in 1985. A year later, it was acquired for $1.25 billion, and its cosmetics brands were so ...
