Studies suggest that 4–5% of trichomonas cases are resistant to metronidazole, which may account for some "repeat" cases. Without treatment, trichomoniasis can persist for months to years in women, and is thought to improve without treatment in men. Women living with HIV infection have better cure rates if treated for seven days rather than with one dose.Topical treatments are less effective than oral antibiotics due to Skenes gland and other genitourinary structures acting as a reservoir. Epidemiology
There were about 58 million cases of trichomoniasis in 2013. It is more common in women (2.7%) than males (1.4%). It is the most common non-viral STI in the U.S., with an estimated 3.7 million prevalent cases and 1.1 million new cases per year. It is estimated that 3% of the general U.S. population is infected, and 7.5–32% of moderate-to-high risk (including incarcerated) populations. References

Fludrocortisone, sold under the brand name Florinef, among others, is a corticosteroid used to treat adrenogenital syndrome, postural hypotension, and adrenal insufficiency. In adrenal insufficiency, it is generally taken together with hydrocortisone. Fludrocortisone is taken by mouth and is most commonly used in its acetate form.Common side effects of fludrocortisone include high blood pressure, swelling, heart failure, and low blood potassium. Other serious side effects can include low immune-system function, cataracts, muscle weakness, and mood changes. Whether use of fludrocortisone during pregnancy is safe for the fetus is unknown. Fludrocortisone is mostly a mineralocorticoid, but it also has glucocorticoid effects.Fludrocortisone was patented in 1953. It is on the World Health Organizations List of Essential Medicines. Medical uses
Fludrocortisone has been used in the treatment of cerebral salt-wasting syndrome. It is used primarily to replace the missing hormone aldosterone in various forms of adrenal insufficiency such as Addisons disease and the classic salt-wasting (21-hydroxylase deficiency) form of congenital adrenal hyperplasia. Due to its effects on increasing Na+ levels, and therefore blood volume, fludrocortisone is the first-line of treatment for orthostatic intolerance and postural orthostatic tachycardia syndrome (POTS). It can be used to treat low blood pressure.Fludrocortisone is also a confirmation test for diagnosing Conns syndrome (aldosterone-producing adrenal adenoma), the fludrocortisone suppression test. Loading the patient with fludrocortisone would suppress serum aldosterone level in a normal patient, whereas the level would remain elevated in a Conns patient. The fludrocortisone suppression test is an alternative to the NaCl challenge (which would use normal saline or salt tablets).
