It can also develop after an episode of Impetigo or any group A streptococcal infection in the skin (this differs from acute rheumatic fever which only follows group A streptococcal pharyngitis). It is the result of the autoimmune response to the streptococcal infection affecting part of the kidney. Persons present with what is called acute nephritic syndrome, in which they have high blood pressure, swelling, and urinary abnormalities. Urinary abnormalities include blood and protein found in the urine, as well as less urine production overall. Poststreptococcal reactive arthritis: The presentation of arthritis after a recent episode of group A streptococcal pharyngitis raises suspicion for acute rheumatic fever, since it is one of the Jones criteria for that separate complication. But, when the arthritis is an isolated symptom, it is referred to as poststreptococcal reactive arthritis. This arthritis can involve a variety of joints throughout the body, unlike the arthritis of acute rheumatic fever, which primarily affects larger joints such as the knee joints. It can present less than 10 days after the group A streptococcal pharyngitis. Cause
Strep throat spreads by close contact among people, via respiratory droplets (for example, saliva or nasal discharge). A person in close contact with another person infected with group A streptococcal pharyngitis has a 35% chance of becoming infected. One in ten children who are infected with group A streptococcal pharyngitis will develop scarlet fever.
This rugae aids in sexual stimulation by becoming lubricated, distended, and expanded.Genitourinary effects of low estrogen include thinning of the vaginal epithelium, loss of vaginal barrier function, decrease of vaginal folding, decrease of the elasticity of the tissues, and decrease of the secretory activity of the Bartholin glands, which leads to traumatization of the vaginal mucosa and painful sensations. This thinning of the vaginal epithelium layers can increase the risk of developing inflammation and infection, such as urinary tract infection.The vagina is largely dominated by bacteria from the genus Lactobacillus, which typically comprise more than 70% of the vaginal bacteria in women. These lactobacilli process glycogen and its breakdown products, which result in a maintained low vaginal pH. Estrogen levels are closely linked to lactobacilli abundance and vaginal pH, as higher levels of estrogen promote thickening of the vaginal epithelium and intracellular production of glycogen. This large presence of lactobacilli and subsequent low pH levels are hypothesized to benefit women by protecting against sexually transmitted pathogens and opportunistic infections, and therefore reducing disease risk. Diagnosis
Hypoestrogenism is typically found in menopause and aids in diagnosis of other conditions such as POI and functional amenorrhea. Estrogen levels can be tested through several laboratory tests: vaginal maturation index, progestogen challenge test, and vaginal swabs for small parabasal cells. Menopause
Menopause is usually diagnosed through symptoms of vaginal atrophy, pelvic exams, and taking a comprehensive medical history consisting of last menstruation cycle.
