Risk factors for ectopic pregnancy include previous ectopic pregnancy, current intrauterine device use, prior fallopian tube surgery, previous pelvic inflammatory disease and a prior history of infertility. Abdominal pain is the most common symptom, followed by amenorrhea or vaginal bleeding, nausea, vomiting, syncope and dizziness. Referred shoulder pain following the onset of abdominal pain is characteristic of intraperitoneal bleeding and, in the appropriate clinical setting, strongly suggests a ruptured ectopic pregnancy. A coordinated evaluation includes measurement of serum human chorionic gonadotropin concentration and transabdominal or, preferably, transvaginal ultrasonography. Treatment is primarily by one of a variety of surgical techniques. Medical therapy with methotrexate or other drugs is currently under investigation.

This study analyzes the clinicopathologic findings in patients with ectopic pregnancy (EP), and deals with the differential diagnosis of the EP, intrauterine pregnancy (IUP), and pelvic inflammatory disease (PID). We evaluated 346 patients with suspected EP. Among those, 119 patients had EP, 82 had IUP, and 55 had PID without pregnancy. The incidence of EP was 1/32.9 live births. Comparing with the other groups, the patients with EP were slightly older, gave a history of previous pregnancies, had acute abdominal pain, nausea, vomiting, dizziness, and fainting, and had direct and rebound abdominal tenderness, pain on motion of the cervix, absence of a pelvic mass, and bilateral adnexal or cul de sac fullness. Culdocentesis was accurate in 95.1% of EP cases. Salpingectomy was performed in 89.9% of the patients with EP. The patients with EP had gross evidence of PID at the surgery in 31% and microscopic evidence of tubal inflammation in 19.4% of cases.

Recent cohort and case control studies of low-dose combined oral contraceptives (COCs) containing the new generation of progestogens have allowed classification of adverse effects into those which are rare but serious and should be considered risks and those which are more frequent but are less of a threat to health. Low-dose COCs continue to affect coagulation in a complex way, but the risk is less than with the older preparations, and it can be minimized by screening women for a personal or familial history of early or unusual thrombosis and for levels of protein C, S, and antithrombin III. Women with true migraine with focal signs should also avoid using COCs. The relative risk of myocardial infarction (MI) may increase from 4:1 in women with one risk factor (age, smoking, hypertension, hyperlipidemia, and diabetes) to 20:1 with two risk factors and 128:1 with three or more risk factors. In the absence of all risk factors, a recent study indicated that the relative risk of MI with COC use was 1.9 for current and past use. COC use also causes a slight increase in hypertension in most women, especially those who are older or have a family history of hypertension. While the COC can affect carbohydrate and lipid metabolism, the new generation of progestogens has reduced these effects. The COC may accelerate presentation of gallbladder disease in predisposed women. The COC protects against benign breast disease but may increase the risk of breast cancer and cervical cancer slightly. There is a strong link between hepatocellular adenoma and COC use, but the incidence is low. Return to fertility after use has not been a problem. Both estrogenic adverse effects (nausea, dizziness, irritability, weight gain, bloating) and progestogenic adverse effects (vaginal dryness, acne, hirsutism, weight gain, depression, loss of libido) can occur in 50% of women, but these generally disappear after a few months of use. In conclusion, the low-dose, third generation COCs are associated with minimal risks in the absence of other risk factors and have many beneficial effects such as the prevention of ovarian and endometrial cancer; a decrease in pelvic inflammatory disease and ectopic pregnancies; and protection from anemia, primary dysmenorrhea, functional ovarian cysts, and benign breast disease as well as from the morbidity and mortality associated with pregnancy.

A retrospective study of ectopic pregnancies seen in Korle Bu Teaching Hospital from January 1991 to December 1993 was conducted. The incidence was 39.5/1000 deliveries; patients with ectopic were not of lower parity than those with normal pregnancies. The incidence of historical predisposing factors was 11.08%, although findings at operation indicated a much higher incidence of previous pelvic inflammatory disease (PID). Dizziness/fainting and abdominal distension were more frequent than has been reported elsewhere. This was due to a very high incidence of ruptured ectopic pregnancies (98.1%) with mean volume of haemoperitoneum of 1.37 l. 16.3% of patients were misdiagnosed initially. The second commonest site of tubal pregnancy, after the ampullary region, was cornual. The case fatality rate was 27.9/1000, with more than half of the deaths occurring before or soon after arrival in hospital. In order to reduce the incidence of ruptured ectopic pregnancies we suggest, among other measures, that appropriate diagnostic facilities be provided.

This report summarizes a meeting of the IPPF International Medical Advisory Panel (IMAP) held in November, 1986, at which information on steroidal oral contraception (OC), Acquired Immunodeficiency Syndrome (AIDS), and female sterility were discussed. Regarding the multiphasic OC now in use, the benefits to health and well-being outweigh the possible side-effects and infrequent complications. Use is associated with a lower incidence of pelvic inflammatory disease, 96-98% effective prevention of pregnancy, a protective effect against ovarian and endometrial cancer, and regulation of erratic menstrual cycles. Minor side effects include nausea, vomiting, dizziness, headache, fluid retention, and inter-menstrual spotting. Adverse effects are circulatory system disease, myocardial infarction, venous thromboembolism, elevated blood pressure, and liver disease. Data on possible carcinogenicity have been conflicting. For women over age 40 OCs should be prescribed with caution. IMAP also drew up recommendations to assist FPAs to play a more active role in controlling the spread of AIDS. An effective program of Information and Education is of primary importance, targeting family planning workers and clients, teachers, parents, and employers. Wide promotion of condom use is a priority. Studies in Africa have revealed a major epidemic of AIDS, with the major mode of transmission heterosexual. The only immediate practical step in prevention of spread is by changes in sexual behavior. The last topic discussed is that of sterility in African women. The naturally occurring level of infertility expected in all populations of women is 3%; high levels in Africa vary by region from 3-32%. These levels of sterility are acquired through infection with Neisseria gonorrheae and Chlamydia trachomatis. Silent infection of women with Chlamydia make treatment especially difficult.

Levonorgestrel-releasing implants are long acting contraceptives, approved for 5 years of continuous use. Two marketed systems, the six capsule Norplant use of tradenames is for product identification purposes only and does not imply endorsement. and the two rod Jadelle, have essentially equal rates of drug release, pregnancy and adverse events over 5 years of use. Randomised clinical trials and controlled cohort observations indicate that for the first 3 years, when pregnancy rates are at or almost zero, no other contraceptive system is more effective, although etonogestrel implants provide equal effectiveness. Annual pregnancy rates rise in the fifth year of continuous use but remain below 1 per 100 women. Annual pregnancy rates of Norplant users remain below 1 per 100 throughout 7 years of continuous use. Levonorgestrel implants provide low progestogen doses; 40-50 microg/day at 1 year of use, decreasing to 25-30 microg/day in the fifth year. Serum levels of levonorgestrel at 5 years are 60-65% of those levels measured at 1 month of use. Adverse effects with levonorgestrel implants are similar to those observed with progestogen only and combined oral contraceptives. Risks of ectopic pregnancy, other pregnancy complications and pelvic inflammatory disease are reduced in comparison with those of women using copper or non-medicated intrauterine devices. Risks of developing gallbladder disease and hypertension or borderline hypertension, although small, are about 1.5 and 1.8 times greater, respectively, in women using levonorgestrel implants than in women not using hormonal contraception. Other serious diseases have not been found to occur significantly more frequently in levonorgestrel implant users than in women not using hormonal contraception. The great majority of levonorgestrel implant users experience menstrual problems, but serious bleeding problems are not more frequent than in controls. Other health problems reported more frequently by levonogestrel implant users than by women not using hormonal contraception in a study of 16000 women included skin conditions, headache, upper limb neuropathies, dizziness, nervousness, malaise, minor visual disturbances, respiratory conditions, arthropathies, weight change, anxiety and non-clinical depression. Clinical depression is not more frequent in women using implants compared with those not using hormonal contraception (i.e. using intrauterine devices, sterilisation). Removal problems occur less frequently with Jadelle than with Norplant. The mean removal time for Jadelle is half that of Norplant. Levonorgestrel implants in nationally representative scientific samples, in randomised trials, and in controlled cohort studies have continuation rates as high as or higher than any other reversible contraceptive over a duration of 5 years. This would imply that the satisfaction women derive from the contraceptive effectiveness of levonorgestrel implants greatly outweighs the dissatisfaction that may accompany menstrual disturbances and other adverse effects associated with implants.
