NORPLANT progestogen-only implant contraception provides several years of effective protection against pregnancy following a single application. It is reversible whenever desired, with return to normal fertility. Drug release and concentrations are maximal in the first month of use, when a set of six capsules releases approximately 85 micrograms/day of levonorgestrel. Release is 25-30 micrograms/day at 60 months. Circulating drug concentrations and pregnancy rates vary inversely with body weight at placement, but even among heavier women, failure rates are below those of oral contraceptives in the general population. Side-effects are most marked at the initiation of use. Disruption of normal menstrual patterns occurs in 70-80% of recipients initially. Menstrual blood loss is decreased, however, and most women experience modest increases in haemoglobin. Headache, acne, other skin or hair problems, changes of weight and of mood and abdominal pain, are the most common side-effects attributed to NORPLANT contraception. The frequency of occurrence of side-effects diminishes with increased duration of use. The comparative paucity of major side-effects, coupled with the method's convenience and effectiveness and its very long action have made NORPLANT implants highly acceptable in both developing and developed countries.

Progestin only birth control pills appeared on the US market in 1973. As there is no estrogen in these mini pills, they may have fewer dangerous side effects than the combined pills. Some clinics suggest mini pills for women who suffer from estrogen excess side effects. The 3 mini pills available in the U.S. are called Micronor, NOR-QD, and Ovrette. Instructions are presented for patients who are interested in using mini pills. The mini pills most likely work by affecting a women's fertility in several ways: act as a messenger to the woman's ovaries and uterus to prevent the release of an egg; thicken the mucous on the cervix, making it difficult for the sperm to "get through" the cervix and reach the egg; and change the lining of the uterus so that it may not develop properly for the fertilized egg to grow. The mini pills can be 97% effective is used perfectly. The mini pills are only effective for as long as a woman takes them. A woman must take a pill every day to prevent pregnancy. A woman should not use the mini pill if she has or ever has had any of these problems: blood clotting problems in veins; stroke; cancer of the breast or reproductive parts of the body; suspected pregnancy, current pregnancy; and undiagnosed, abnormal genital bleeding. Possible benefits for a woman using mini pills include: an effective method of birth control; a method for nursing mothers since it does not seem to affect the amount of their breast milk; and a possible reduction in premenstrual cramps. Possible risks for a woman using mini pills include: irregular periods; and a less effective method if the patient does not take a pill every day. The danger signals to look for are abdominal pain, chest pain, headaches, eye problems, and severe leg pain. A patient should revisit a clinic in the following situations: has not had a period within 45 days of the last period; severe abdominal pains while taking mini pills; experiences a warning signal; any time one thinks the pills are causing trouble; and once a year for a pap smear, breast examination, and laboratory tests.

A study of 2 low-dose oral contraceptives, Loestrin and Nordette, was conducted in association with the National Family Planning Board in Kota Bharu, Kelantan, West Malaysia, to determine differences in continuation rates and reasons for discontinuation. This report includes analysis of 96 women, 91.7% of whom were interval patients, randomly allocated to 1 of the above OCs between December 1979 and January 1981. Follow-up visits were scheduled at 1, 3 and 6 months after admission with symptom grids completed during the 1st, 3rd, and 6th cycles. The continuation rates at 6 months were 85.9 and 89.8 for Loestrin and Nordette, respectively. The corresponding follow-up rates were 73.9 and 68.3. The side effect reported most often among both groups was breakthrough bleeding (BTB). In addition, the proportion of Loestrin users who reported BTB at least once during the study was significantly higher than the proportion of Nordette users (38.3% versus 18.4%, p 0.05). Other symptoms reported were nausea, headaches, intestinal problems, and abdominal pain. No accidental pregancies were reported during this study. There were a total of 6 (11.8%) discontinuations in the Loestrin group and 4 (8.9%) in the Nordette group.

The acceptability and effectiveness of a progestogen-only oral contraceptive (OC), Ovrette, during lactation were investigated in 200 women recruited from a teaching hospital in Khartoum, Sudan. Ovrette contained 0.075 mg of norgestrel. 69 women (34.5%) had used OCs at some point prior to the index pregnancy. Serious complications (e.g., severe headache, chest pain, leg pain, abdominal pain, blurred vision) were reported by 8 respondents during the 12-month study period. Less serious side effects included dysmenorrhea (49 women), nausea (28 women), dizziness (38 women), vaginal discharge (86 women), headaches (78 women), and breast discomfort (21 women). Overall, 143 women (71.5%) experienced at least 1 side effect. Of the 21 women (10.5%) who discontinued Ovrette use before 12 months, 9 were motivated by menstrual problems and other side effects. The 12-month continuation rate was 89.1%. There were 2 pregnancies, only 1 of which represented method failure. These findings are consistent with previous studies indicating that use of progestin contraceptive agents is associated with more menstrual disturbances and pregnancies than combined OCs. Use of combined OCs is contraindicated during lactation, however.

Ortho Evra is the first transdermal patch approved for the prevention of pregnancy. Comparative trials have shown that Ortho Evra has efficacy similar to the oral contraceptives Mercilon (not available in the United States) and Triphasil for the prevention of pregnancy when used as directed. Adverse effects with Ortho Evra are similar to those reported with combined oral contraceptives, with the exceptions of mild-to-moderate application-site reactions and an increased frequency of breast symptoms. The most commonly reported adverse reactions were breast symptoms, headache, application-site reactions, nausea and vomiting, dysmenorrhea, and abdominal pain. Approximately 5% of study subjects had at least one patch that did not stay attached to their skin, and about 2% of women withdrew from clinical trials due to irritation from the patch. In clinical studies, the patch appeared to be less effective in women weighing more than 90 kg than in women with lower body weights. More research is needed on the relationship between body weight and contraceptive patch efficacy. In two clinical trials, compliance was greater with the patch than with oral contraceptives. Whether this will result in reduced pregnancy rates in general use is unknown. Additional studies are warranted to determine if the patch offers any significant efficacy or safety advantages over current methods of hormonal contraception.

The levonorgestrel-releasing intrauterine device (IUD) (Mirena) is a frequently used and effective method of contraception, with a Pearl index of 0.1. The ectopic pregnancy rate is 0.02 per 100 woman-years. Special attention is needed in situations where pregnancy is detected with a levonorgestrel-releasing IUD in situ, because almost two thirds of these pregnancies are ectopic. We describe one of these rare cases of ectopic pregnancy in a woman aged 37 years, who was admitted to hospital with abdominal pain and vaginal bleeding.

We present an unusual and complicated case of a 39-year-old woman who was admitted three times in hospital over a period of 4 weeks, with abdominal pain initially and then right loin pain, fever and feeling generally unwell. She was investigated on each admission with different diagnoses set each time, but only on her last admission due to persisting symptoms, an MRI scan revealed a tubo-ovarian abscess associated with pelvic inflammatory disease (PID). We believe that the PID had developed secondary to the intrauterine device and a few weeks after the removal of the Mirena coil she was diagnosed with a tubo-ovarian abscess. As the case unfolds, we will introduce the possible diagnoses and causes that were likely to have led to the development of the abscess.

An ectopic pregnancy are most common gynaecological emergencies. The large majority (95%) of ectopic pregnancies occur in Fallopian tube. Although pregnancy is rare in women who use intrauterine system Mirena, women who do become pregnant while using Mirena have a high risk of ectopic pregnancy. These pregnancies can be watchful for any signs of an ectopic pregnancy, such a severe abdominal pain accompanied by unusual vaginal bleeding.
