Separately, searchers near Bronson, Texas, about 140 miles northeast of Houston, recovered what they believed to be one of Columbia’s tires. It sus tained a massive split across its tread, but it was impossible from photographs to know whether the tire was damaged aboard Columbia or when it struck the ground. NASA investigators were confident the gear door di fall off in flight because such a failure would have been indicated on sensor readings. Other NASA officials have cited mysterious sor readings in the wheel well moments before Columbia’s breakup but have said they werei dent the tire didn’t burst inside the shuttle. Daugherty acknowledged in his e-mail that these were “absolute worst-case scenarios” but defended citing them: “You should seriously consider possibility of the gear not deploying at all if there is a substantial breach of the wheel well.” He referred questions about his concerns to NASA spokesman. Agency officials indicated they did not want reporters to speak with Daugherty because accident investigators had not yet ques tioned him. NASA dis- officials in Washington said they could not confirm the tire was the shuttle’s. Engineer Robert H. Daugherty, responding to a query from Johnson Space Center, cautioned NASA colleagues in remarkably strident lan guage that damage to delicate insulating tiles near Columbia’s land ing gear door could cause one or more tires inside to burst, perhaps ending with catastroph ic failures that would place the seven astro nauts “in a world of hurt.” Engineer warned NASA on tire failure Internal e-mails released Wednesday, showed that a NASA engineer warned extreme temperatures during descent could cause tires to burst, inside the wheel well, blowing the door off and leading to catastrophic failure. Left wing Elavon line temperature Sensors for temperature and tire pressure readings during the final minutes of flight, indicated problems in the left wing. Feb 1. 6:58 a m. EST Sensors Elevon skin temperature SOURCE: NASA closed the contents c his e-mail Wednesday. The e-mail fror Daugherty, an engineer at NASA’s Langley research facility Hampton, Va., was prompted by a tele phone call Jan. 27 experts at the Johnser Space Center Houston who asked what might happen Columbia’s tires wett not inflated when attempted to land. The inquiry fn Johnson has attracted interest because it cat four days after neers at The Boei® Such an explosion inside Columbia’s belly, Daugherty predicted, could blow out the gear door and expose the shuttle’s unprotected innards to searing temperatures as it raced through earth’s atmosphere. Even if astronauts survived the heat, the blast could damage critical systems inside the wheel compartment, prevent the landing gear on one side from lowering, necessitate a risky belly landing or force the crew to bail out, Daugherty wrote. Bailing out would be “not a good day,” he wrote. But attempting to fly the shuttle with only one side’s landing gear lowered would be worse: “You’re fin ished.” Flight Director Leroy Cain said Wednesday that Co., a contractor, assured NASA that Columte could return safely despite damage to left wing tiles that might have occurred on liftoff. Senior NASA officials said Daugherty’s i cems were part of a “what-if” analysis by a si group of engineers who already had been assi that Columbia would land safely. They acknowl edged that concerns about threats to the si tires were not passed along to NASA flight direc tors. Milt Heflin, chief of the flight director’s said Daugherty and others involved in the tire ques tions “were happy with the analysis and the that was done” by Boeing. “They were continums to do more what-if’ing.” Thursday, NAS/ Continu unrealistic told the pa time you n Sen.

It does not protect against HIV infection (AIDS) and other sexually transmitted diseases. What is DEPO-PROVERA Contraceptive Injection? DEPO-PROVERA Contraceptive Injection is a form of birth control that is given as an intramuscular injection (a shot) in the buttock or upper arm once every 3 months (13 weeks). To continue-your contraceptive protection, you must return for your next injection promptly at the end of 3 months (13 weeks). DEPO-PROVERA contains medroxyprogesterone acetate, a chemical similar to (but not the same asl the natural hormone progesterone, which is produced by your ovaries during the second half of your menstrual cycle. DEPO-PROVERA acts by preventing your egg cells from ripening. If an egg is not released from the ovaries during your menstrual cycle, it cannot become fertilized by sperm and result in pregnancy. DEPO-PROvERA also causes changes in the lining of your uterus that make it less likely for pregnancy to occur How effective is DEPO-PROVERA Contraceptive Injection? The efficacy of DEPO-PROVERA Contraceptive Injection depends on following the recommended dosage schedule exactly (see ''How often do I get my shot of DEPO-PROVERA Contraceptive Injection? 1 '). To make sure you are not pregnant when you first get DEPO-PROVERA Contraceptive Injection, your first injection must be given ONLY during the first 5 days of a normal menstrual period; ONLY within the first 5 days after childbirth if not breast-feeding; and, if exclusively breast-feeding, ONLY at the sixth week after childbirth. It is a long-term injectable contraceptive when administered at 3-month (13-week) intervals. DEPO-PROVERA Contraceptive Injection is over 99% effective, making it one of the most reliable methods of birth control available. This means that the average annual pregnancy rate is less than one for every 100 women who use DEPO-PROVERA. The effectiveness of most contraceptive methods depends in part on how reliably each woman uses the method. The effectiveness of DEPO-PROVERA depends only on the patient returning every 3 months (13 weeks) for her next injection. Your health-care provider will help you compare DEPO-PROVERA with other contraceptive methods and give you the information you need in order to decide which contraceptive method is the right cnoice for you. The following table shows the percent of women who got pregnant while using different kinds of contraceptive methods. It gives both the lowest expected rate of pregnancy (the rate expected in women who use each method exactly as it should be used) ana the typical rate of pregnancy (which includes women who became pregnant because they forgot to use their birth control or because they did not follow the directions exactly).

You should not use DEPO-PROVERA if you have any of the following conditions: • if you think you might be pregnant • if you have any vaginal bleeding without a known reason • if you have had cancer of the breast • if you have had a stroke • if you have or have had blood clots (phlebitis) in your legs • if you have problems with your liver or liver disease • if you are allergic to DEPO-PROVERA (medroxyprogesterone acetate or any of its other ingredients). What other things should I consider before using DEPO-PROVERA Contraceptive Injection? You will have a physical examination before your doctor prescribes DEPO-PROVERA. It is important to tell your health-care provider if you have any of the following; • a family history of breast cancer • an abnormal mammogram (breast, x-ray), fibrocystic breast disease, breast nodules or lumps, or bleeding from your nipples • kidney disease • irregular or scanty menstrual periods • high blood pressure • migraine headaches • asthma • epilepsy (convulsions or seizures) • diabetes or a family history of diabetes • a history of depression • if you are taking any prescription or over-the-counter medications This product is intended to prevent pregnancy. It does not protect against transmission of HIV (AIDS) and other sexually transmitted diseases such as chlamydia, genital herpes, genital warts, gonorrhea, hepatitis B, and syphilis. What if I want to become pregnant after using DEPO-PROVERA Contraceptive Injection? Because DEPO-PROVERA is a long-acting birth control method, it takes some time after your last injection for its effect to wear off. Based on the results from a large study done in the United States, for women who stop using DEPO-PROVERA in order to become pregnant, it is expected that about half of those who become pregnant will do so in about 10 months after their last injection; about two thirds of those who become pregnant will do so in about 12 months; about 83% of those who become pregnant will do so in about 15 months; and about 93% of those who become pregnant will dp so in about 18 months after their last injection. The length of time you use DEPO-PROVERA has no effect on how longjt takes you to become pregnant after you stop using it What are the risks of using DEPO-PROVERA Contraceptive Injection? I .Irregular Menstrual Bleeding The side effect reported most frequently by women who use DEPO-PROVERA for contraception is a change in their normal menstrual cycle. During the first year of using DEPO-PROVERA, you might have one or more of the following changes: irregular or unpredictable bleeding or spotting, an increase or decrease in menstrual bleeding, or no bleeding at all. Unusually heavy or continuous bleeding, however is not a usual effect of DEPO-PROVERA; and if this happens, you should see your health-care provider right away. With continued use of DEPO-PROVERA, bleeding usually decreases, and many women stop having periods completely. In clinical studies of DEPO-PROVERA, 55% of the women studied reported no menstrual bleeding (amenorrhea) after I year of use, and 68% of the women studied reported no menstrual bleeding after 2 years of use. The reason that your periods stop is because DEPO-PROVERA causes a resting state in your ovaries. When your ovaries do not release an egg monthly, the regular monthly growth of the lining of your uterus does not occur and, therefore, the bleeding that comes with your normal menstruation does not take place. When you stop using DEPO-PROVERA your menstrual period will usually, in time, return to its normal cycle. 2.Bone Mineral Changes Use of DEPO-PROVERA may be associated with a decrease in the amount of mineral stored in your bones. This could increase your risk of developing bone fractures. The rate of bone mineral loss is greatest in the early years of DEPO-PROVERA use, but after that, it begins to resemble the normal rate of age-related bone mineral loss. J.Cancer Studies of women who have used different forms of contraception found that women who used DEPO-PROVERA for contraception had no increased overall risk of developing cancer of the breast, ovary, uterus, cervix, or liver However women under 35 years of age wnose first exposure to DEPO-PROVERA was within the previous 4 to 5 years may have a slightly increased risk of developing breast cancer similar to that seen with oral contraceptives. You should discuss this with your health-care provider ^Unexpected Pregnancv Because DEPO-PROVERA is such an effective contraceptive method, the risk of accidental pregnancy for women who get their shots regularly (every 3 months [13 weeks]) is very low. While there have been reports of an increased risk of low birth weight and neonatal infant death or other health problems in infants conceived close to the time of injection, such pregnancies are uncommon. If you think you may have become pregnant while using DEPO-PROVERA for contraception, see your health-care provider as soon as possible. SAIIergic Reactions Some women using DEPO-PROVERA Contraceptive Injection have reported severe and potentially life-threatening allergic reactions known as anaphylaxis and anaphylactoid reactions. Symptoms include the sudden onset of hives or swelling and itching of the skin, breathing difficulties, and a drop in blood pressure. d.Other Risks Women who use hormone-based contraceptives may have an increased risk of blood clots or stroke. Also, if a contraceptive method fails, there is a possibility that the fertilized egg will bq to develop outside of the uterus (ectopic pregnancy). While these events are rare, you shoi tell your health-care provider if you have any of the problems listed in the next section. What symptoms may signal problems while using DEPO-PROVERA Contraceptive Injection? Call your health-care provider immediately if any of these problems occur following an injection of DEPO-PROVERA: • sharp chest pain, coughing up of blood, or sudden shortness of breath (indicating a possible dot in the lung) • sudden severe headache or vomiting, dizziness or fainting, problems with your eyesight or speech, weakness, or numbness in an arm or leg (indicating a possible stroke) • severe pain or swelling in the calf (indicating a possible clot in the leg) • unusually heavy vaginal bleeding • severe pain or tenderness in the lower abdominal area • persistent pain, pus, or bleeding,at the injection site What are the possible side effects of DEPO-PROVERA Contraceptive Injection? 1. Weight Cain You may experience a weight gain while you are using DEPO-PROVERA. About two thirds of the women who used DEPO-PROVERA in clinical trials reported a weight gain of about 5 pounds during the first year of use. You may continue to gain weight after the first year Women in one large study who used DEPO-PROVERA for 2 years gained an average total of 8.1 pounds over those 2 years, or approximately 4 pounds per year Women who continued for 4 years gained an average total of 13.8 pounds over those 4 years, or approximately 3.5 pounds per year Women who continued for 6 years gained an average total of 16.5 pounds over those 6 yean, or approximately 2.75 pounds per year 2.0ther Side Effects In a clinical study of over 3,900 women who used DEPO-PROVERA for up to 7 years, some women reported the following effects that may or may not have been related to their use of DEPO-PROVERA: Irregular menstrual bleeding, amenorrhea, headache, nervousness, abdominal cramps, dizziness, wea&iess or fatigue, decreased sexual desire, leg cramps, nausea, vaginal discharge or irritation, breast swelling and tenderness, bloating, swelling of the hands or let backache, depression, insomnia, acne, pelvic pain, no hair growth or excessive hair loss, rash, hot flashes, and joint pain. Other problems were reported by very few of the women in the clinical trials, but some of these could be serious. These include convulsions, jaundice, urinary tract infections, allergic reactions, fainting, paralysis, osteoporosis, lack of return to fertility, deep van thrombosis, pulmonary embolus, breast cancer or cervical cancer If these or any other problems occur during your use of DEPO-PROVERA, discuss them with your health-care provider. Should any precautions be followed during use of DEPO-PROVERA Contraceptive Injection? ■I.Missed Periods During the time you are using DEPO-PROVERA for contraception, you may skip a period,orpr periods may stop completely. If you have been receiving your DEPO-PROVERA injections regularly every 3 months (13 weeks), then you are probably not pregnant. However if you think that you may be pregnant, see your health-care provider 2. Laboratory Test interactions If you are scheduled for any laboratory tests, tell your health-care provider that you are using DEPO-PROVERA for contraception. Certain blood tests are affected by hormones such as DEPO-PROVERA. J.Drug Interactions Cytadren (aminoglutethimide) is an anticancer drug that may significantly decrease the effectiveness of DEPO-PROVERA if the two drugs are given during the same time. 4.Nursing Mothers Although DEPO-PROVERA can be passed to the nursing infant in the breast milk no harmful effects nave been found in these children. DEPO-PROVERA does not prevent the breasts from producing milk so it can be used by nursing mothers. However to minimize the amount of DEPO-PROVERA that is passed to the infant in the first weeks after birth, you should wait until 6 weeks after childbirth before you start using DEPO-PROVERA for contraception. How often do I get my shot of DEPO-PROVERA Contraceptive Injection? The recommended dose of DEPO-PROVERA is 150 mg every 3 months (13 weeks) given in a single intramuscular injection in the buttock or upper arm. To make sure that you are not pregnant at the time of the first injection, it is essential that the injection be given ONLY during the frst 5 days of a normal menstrual period. If used following the delivery of a child, the first injection of DEPO-PROVERA MUST be given within 5 days after childbirth if you are not breast-feeding or 6 weeks after childbirth if you are exclusively breast-feeding. If you wait longer than 3 months (13 weeks) between injections, or longer than 6 weeks after delivery, your health-care provider should determine that you are not pregnant before giving you your injection of DEPO-PROVERA Rx only CB-7-S Pharmacia & Upjohn Company Kalamazoo, Ml 49001, USA Pharmacia & Upjohn attacks.
