Many women, particularly adolescent women, suffer from painful menstrual cramps, medically referred to as dysmenorrhea. Common treatments for menstrual cramps are non-steroidal anti-inflammatory drugs and oral contraceptives, but both have side effects that limit their use. Injection of vitamin K into an acupuncture point has been used as treatment for dysmenorrhea at the Obstetrics & Gynecology Hospital in Shanghai, China since at least 1985. More research is needed on the effectiveness of this treatment and its acceptability to different women. The objective of this study is to examine the feasibility and effectiveness of acupoint injection of vitamin K1 for the treatment of severe primary dysmenorrhea in the United States. Twenty participants will be randomized to receive either 1) vitamin K1 injection into an acupuncture point at the start of their menstrual cycle followed by a saline injection in a non-acupuncture point two months later or 2) saline injection in a non-acupuncture point followed by vitamin K1 injection into an acupuncture point two months later. The primary outcome measure will be change in pain intensity measured before and after each treatment. Data on other menstrual symptoms will be collected by telephone or a web-based survey. Three additional participants will be recruited to receive vitamin K1 injection into an acupuncture point and have blood samples drawn before and after injection to determine absorption of vitamin K1. The aims of the study are to collect preliminary data on the efficacy and safety of vitamin K1 injected in an acupoint for the treatment of severe primary dysmenorrhea; assess the feasibility and acceptability of the treatment among U.S. women; and test the blood absorption of vitamin K1 following acupoint injection treatment.
The investigators hypothesize that:
1. Vitamin K1 acupoint injection is a safe treatment for women with menstrual pain.
2. Vitamin K1 acupoint injection reduces menstrual pain more than placebo saline injection does.
3. The treatment of vitamin K1 acupoint injection is acceptable to U.S. women.
4. Vitamin K1 is absorbed into the blood thru acupoint injection.

Intradermal injection of a heated (pasteurized) saline suspension of sarcoid tissue obtained from a sarcoid spleen or lymph node. In patients with active sarcoidosis a dusky red nodule develops slowly over the next few weeks at the injection site. Histologic examination, an essential part of the complete test, reveals sarcoid tissue.
Adverse reactions that occur initially at the site of injection or infusion. Milder type is confined to a local allergic flare reaction. A more severe reaction is caused by extravasation of VESICANTS from the blood vessel at the site of injection and can cause damage to the surrounding tissue. In tumor flare reaction symptoms involve well beyond the injection site such as an increase in the tumor size and tumor markers levels, bone pain, and HYPERCALCEMIA.
Total or subtotal destruction of the pituitary gland by chemical injection. It is usually achieved by injection of ethyl alcohol via trans-sphenoidal cannulation under stereotaxic control. It is usually performed for the treatment of intractable pain.
Hemorrhagic necrosis that was first demonstrated in rabbits with a two-step reaction, an initial local (intradermal) or general (intravenous) injection of a priming endotoxin (ENDOTOXINS) followed by a second intravenous endotoxin injection (provoking agent) 24 h later. The acute inflammation damages the small blood vessels. The following intravascular coagulation leads to capillary and venous THROMBOSIS and NECROSIS. Shwartzman phenomenon can also occur in other species with a single injection of a provoking agent, and during infections or pregnancy. Its susceptibility depends on the status of IMMUNE SYSTEM, coagulation, FIBRINOLYSIS, and blood flow.
The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.
