Editorial

Topic of this issue needs a different protocol for male GPs in Pakistan.Proper internal examination is missing for them.Ladies do not come out even with specific history.Physician has to confirm by direct questioning what patient means with indirect references to gynaecological problems and it needs lot of experience and verstality in our population.

After lot of discussions ,heart burn and modifying again and again,Dr Mehboob Ashraf and Dr Saadia have developed specific protocols on Vaginal discharge,pelvic pain,and contraception.This is an innovation.They must be congratulaed.This is specifically targeted to conditions in our settings.It may not be perfect but still it is practical for male family physicians.Somewhere else for some body else,something else may be needed.

Dr Mehboob Ashraf and Dr Liaqat Ali have written only those specific problems with which they have some experience.Dr Saadia was requested to write up those issues which need experience of Gynaecologist.She has made all practical arrangements for the interview ,meeting and this journel.PSFP Gujranwala is indebted to her for this.

Dr Saadia has written superbly.Her skill of writing in brief ,crisp and sharp phrases must be natural..She has very good radar to read the requirements of family physicians.She has taken lot of pains to write in present format.She is most welcome aboard.She is requested to keep on writing regularly for us.

Brief advice for family physicians.


Menstrual Disorders and Abnormal Vaginal Bleeding


In Neonates


In Children


Imperforate hymen

In girls of 14-16 yrs of age presenting with primary amenorrhoea, swelling in the lower abdomen and cyclic, monthly pain one should think of this condition. Sometimes these patients present with acute urinary retention. Inspection of external genitalia will show a bulging bluish membrane, which is imperforate hymen. Ultrasound confirms the diagnosis. Simple incision under general anaesthesia is good enough.


Menarche, Adolescence and Puberty


In 20-40 years age

In more than 40 years age
Use of progestogens in pregnancy


Bleeding in pregnancy is always abnormal. Use of progestogens for early pregnancy bleeding is not of much benefit. First trimester miscarriages usually are due to an abnormal conceptus and as such progestogens will not have any effect.


Oligomenorrhoea


Oligomenorrhoea is infrequent menstruation, i.e., the duration of menstrual cycle is longer than normal, which is 21 to 35 days. It may be routine matter for any single patient.

Hirsutism and obesity usually accompany oligomenorrhoea in polycystic ovaries. The condition of polycystic ovaries (PCO) is fairly common, the incidence being 22%. Ultrasound examination demonstrates the typical appearance of these ovaries.

Hyperprolactinaemia can be a cause in which case galactorrhoea may be present.

Dysmenorrhoea

Primary dysmenorrhoea is quite common. History can demonstrate that mothers, who had this problem, usually have daughters with the same complaint. Conservative approach with reassurance and explanation is all that may be needed. If pain is severe then simple NSAIDS like Ponstan or Brufen tid for 2-3 days can be good enough.

In persistent cases to rule out organic cause ultrasound as an initial investigation should be done. Endometriosis is an example of the organic causes.

Hyperemesis Gravidarum

Family physicians are often confronted with this problem. Hyperemesis gravidarum is excessive vomiting to the extent that the patient cannot retain any food or water leading to severe depletion. Nothing should be given by mouth for 2-3 days to break the cycle of vomiting. Fluids and electrolytes should be given by I/V route. One litre each of Ringer's lactate, 10 % Dextrose, Dextrose / Normal saline can roughly meet the daily needs. Hospital admission brings change of environment for the patient and should not be delayed as severe condition can affect liver function and patient may develop jaundice

For vomiting frequency of 2-3/day the patient should be reassured. She should be advised to have intervals between taking solid food and liquids. Navidoxine one tablet thrice a day half-hour before meals is quite helpful.

Air hunger / Breathlessness in late pregnancy

It is due to physical effects of pregnancy along with the effects of progesterone. Palpitation and breathlessness when only due to these factors needs only explanation and reassurance.

Hirsutism / PCO

Hirsutism, excessive facial hair, is not an uncommon complaint. It may be familial, therefore, history of the problem in mother or sister should be elicited.

Usually hirsutism is accompanied with menstrual abnormality (oligomenorrhoea or even amenorrhoea) and weight gain. Married women may also present with infertility. As such it is part of polycystic ovarian disease (PCO) for the diagnosis of which ultrasound is quite helpful. Obesity plays an important role in the hormonal disturbance of this condition.

Young unmarried girls:

For married women:

Early warning for malignancy in gynaecology

Ovarian Cysts

With the wider use of ultrasound examination, reporting of ovarian cysts has increased tremendously. The fact that the graffian follicle may reach a size of 2.5 cm before releasing the oocyte should be kept in mind. Criteria for management are simple. Cysts of 4-5 cm should be taken as follicles that have failed to rupture giving rise to functional cysts of the ovary. These should be monitored by repeat ultrasound examinations at monthly intervals. If they continue to grow in size, operative management would be required. Most of these gradually become smaller and disappear spontaneously. In good compliance patients, especially of younger age, cysts of even 7-8 cm size may be observed by periodic ultrasound.


Lower abdominal pain / Backache



Vaginal discharge


First of all it should be decided whether it is normal or abnormal. There is some discharge (secretions) present in the vagina normally to keep it comfortably moist. Sometimes there is excess of this normal discharge and apart from its amount there is no other complaint. This happens in mid cycle, during pregnancy, with contraceptive pills or when there is cervical ectopy (previously called erosion). Cervical ectopy may require cauterisation; in all other cases reassurance is all that is needed.


Abnormal vaginal discharge is accompanied with smell and vaginal discomfort or itching. Common varieties are as follows:

  1. Trichomoniasis

The discharge may be watery, frothy and creamy, greyish or greenish in colour and is accompanied with itching. A convenient treatment is single dose of metronidazole 2 gm each for both partners followed by abstinence for one week.

  1. Monilial infection

This is common in pregnancy, in diabetic women or in those who have recently taken broad spectrum antibiotics. The patient complains of itching and whitish curdy discharge. Common treatments are either single dose clotrimazole vaginal pessary or nystatin vaginal pessaries for two weeks. There are many other effective local preparations besides oral single dose preparations like fluconazole.

  1. Bacterial vaginosis

This is a condition in which normal vagina flora is replaced by anaerobes. The resultant discharge produces a fishy smell. Treatment consists of metronidazole with doxycycline or one of the quinolones for five days.


Hormone Replacement Therapy


Hormone replacement therapy (HRT) is now widely recommended to postmenopausal women not only for alleviation of menopausal symptoms but also for other benefits. These include a general sense of wellbeing, prevention of osteoporosis and cardiovascular benefits. HRT improves quality of life. Concern regarding increased chances of CA breast with HRT use can be put into perspective by the fact that the incidence of CA breast in general population is estimated at 45/1000. After 5 years of use it rises to 47/1000, after 10 years 50/1000, and after 15 years 57/1000. Patient and physician can make an educated decision after going through these figures.


Usually HRT is started after the menopause is established, which means six months after the last periods. Some women, due to their symptoms, may require HRT in the peri-menopausal period when their menses have not stopped altogether but are infrequent. If there is any abnormal bleeding that should be investigated first.


Following workup should be done before instituting HRT:

  1. Examination of breasts for lumps.

  2. Lipid profile.

  3. Mammography.

If there is irregular spotting during the therapy, Pap smear and specialist consult should be obtained.

Rational use of drugs.

A doctor’s job is to prescribe drugs. Rational prescriptions are expected. How it is that more and more irrational prescription are now in circulation. Quacks try to copy the routines of doctors. When doctors are not applying their knowledge or not acquiring required knowledge, how can we lament and complain incessantly about the quackery?

Following groups of drugs are being overprescribed and on many occasions without any indication.

Antibiotics.

Should not be prescribed for all sorts of vaginal discharge. These may aggravate and on some occasions cause fungal infections.

Local Steroid applications.

These are being misused to treat pruritis vulvae. Steroid applicaion augment the problem.

Dettol Wash

To treat vulvitis. This is another cause to initiate the damaged skin and worsen the damage.

Antiemetics.

In first trimester use of these must be very limited. Councilling and the modefying the diet and dieteray intake can be of more help.

Iron and Ca Supplements.

are being misused in first trimester. These are not required at this time. These may cause teratogenic effects like other drugs. Gastric irritation may be another reason to avoid.

Oral hypoglycemics.

There is no reason on the earth for these drugs during pregnancy.

Venotlin Tab.

Is being misused for abortions. They have only limited rule to delay preterm labour.

List of safe drugs during pregnancy.

Should be kept on desk for ready reference.

Progesteron

Is being misused in first trimester to treat threatened abortion. It can not prolong pregnancy, if this is going to abort.

Infertility and Empirical Use of Clomophene.

All cadres of physicians are overprescribing this drug. It is a powerful drug and should never be given without proper indications.

Uses of Clomiphene.

Induction of ovulation 50 –150 mg/day for 5 days starts on 2nd day of periods.

Some cases of Oligospermia. 50 mgs/day for 90 days with the gap of 5 days after every 25 days.

Pre requisites for use of Clomiphene.

  1. All causes for infertility other than anovulation should be ruled out.

  2. Liver functions must be normal.

  3. Hypothalamic –Pituatary function should be intact.

  4. Some degree of ovarian function should be present. It is best suited to the persons with low levels of Gonadotrophins and high levels of E.

Contraindications.

Liver impairment

Patients with ovarian cysts and masses. Drug itself has the tendency to cause cystic changes in the ovaries due to overstimulation.

Side effects.

Overstimulation of ovaries resulting into pain & enlargement, cystic changes and multiple pregnancies.

Relevant Physiology.

Clinically relevant actions of Hormones.

Estrogens.

  1. Determines secondary sex characters
    feminine curves, soft skin, luxuriant scalp hair, development of breast at puberty, and shyness etc.

  2. Development and Stimulation of secondary sex organs.
    Development of Vulva, Vagina, glands in this area, Changing infantile Uterus to adult form and later on proliferative activity in endometrium and myometrium.

  3. Development of Breast
    by icreasing vascularity, proliferation of cells and deposition of fat. It does not cause lactation, rather it inhibits it. That is why contraceptive pills in lactating women are not recommended.

  4. Acts on Locomotor System.
    Conserves Ca ++, PO4 ----, and encourages bone formation. Growth spruts at puberty and osteoporosis at menopause can clearly be linked to esterogens and justifies the role of HRT (Hormone Replacement Therapy) at menopause.

  5. Lowers the level of Cholesterol levels.
    This may have some bearing on relatively low incidence of coronary thrombosis before menopause.

Progesterone.

Secreted by Corpus luteum and placenta mainly and then by suprarenal cortex.

  1. Mainly taken as hormone of pregnancy.
    Helps in maintaining the pregnancy and developing maternal instinct.

  2. Acts on secondary sex organs only if
    previously primed by estrogens. Otherwise it is practically ineffective. Brings about glandular activity in breast, endometrium of Uterus (during second half of Menstrual cycle), vagina etc. It is important to prepare the breast for lactation but does not initiate the letting down of milk. That is why injectable contraceptives can be comfortably given to lactating mothers.

  3. General effects
    Increases sebum production by sebaceous glands and hence responsible for premenstrual acne and silky hair changes during pregnancy. Relaxes smooth muscles throughout the body. Uterus remains silent. Ligaments are relaxed. Gastric emptying is delayed. Intestinal motility is decreased.

Menstrual cycle.

Gonadotrophin releasing hormones of hypothalamus (GnRh), Gonadotrophins (FSH, LH) in addition to estrogens and progesterone play role in cyclical changes.

Mean duration is 28 days. It can vary from 21 days to 35 days. It is most irregular 2 years before menarche and 3 years before menopause. At both times anovulation is the cause. It is usually divided in 3 phases.

Mensrual phase: Day 1 to Day 4
Two third to four fifth of endometrium is shed due to sudden withdrawl of E and P.Only basal layer which is 1 mm thick, is left behind. It may last from 2nd to 8th day.

Proliferation phase: Day 5 to Day 14
Under the growing effect of Esterogen repair endometrium starts increasing its thickness and vascularity till it is 2-3 mms. Phase lasts till ovulation.

Secretory Phase: Day 15 to Day 28.
After ovulation progesterone is secreted from corpus luteum and this leads to increase in thickness and tortousity of grandular components and at the same time increases vascularity. Thickness becomes 5-7 mms. This phase ends with the sudden withdrawl of E and P and consequent shedding.

History and Examination.

Acute or chronic.

Unilateral Bilateral Pregnancy or no Pregnancy.

Stable General Condition Poor General Condition

History and examination should highlight following important indicators.

If intermittent then think of

If pain is continous then thik of

In all other ladies.If pain is unilateral rule out

If pain is bilateral and associated with vaginal discharge,dysparaenia, Dysmenorrhoea ,low back ache then local examination is required.

Chronic pelvic pain.

Diabetes Mellitus in Ob/Gyn practice.

Paramouont problem is not lack of knowledge with the doctors. It is the communication gap with the patient and then acceptance by her. All doctors know insulin is essential for pregnant Diabetics.Still majority of these diabetics are on oral hypoglycaemics. What is the solution?

Risks to Mothers.

So patients (Pregnant or non-pregnant) with symptoms related to any of above conditions should be routinely screened for DM.

Risks to Foetus.

Neural tube defects like hydrocephalus, anencephaly, Mirocephaly.

VSD, Coartation of Aorta, Cardiomegaly etc,Renal agenesis.

Duedenal and anorectal atresia.

Risks to Neonates.

Hypoglycaemia

Respiratory Distress Syndrome.

Neonatal jaundice.

All deliveries must be in the hospitals.

Varieties of DM in Pregnancy.

Division between Type 1 or 2 i.e. IDDM or NIDDM is insignificant and immaterial, as all patients need insulin. Following division is more practical.

Pregestational DM

Disease is present before pregnancy. So risks can be conveyed to her before pregnancy. Chances of transmitting to siblings can be explained. Here genetics of Type 1 and 2 are different.

Gestational DM

Disease developes only during pregnancy. It disappears after the delivery. They have very high incidence of disease in later life.

_______________________________

Teratology.

Definition: of a teratogenic agent: Any chemical (Drug), infection, physical agent, defeciency state after exposure to foetus alters morphology or function. Period of exposure is determining factor whether malformation is going to be there or not.

Three important periods

Resistant Period: From day 0 to day 11 of gestation, post ovulation. This is the period when it will either be killed by any specific insult or it will survive without any negative effect of the same insult.

Maximum Susceptibility: From day 11 to day 57.Foetus is undergoing differentiation. This the period where chances of tertogenicity are maximum.

Lower Susceptibility: After 57 days (8 weeks gestation) differentiation is completer. Organs have formed. Teratogenic agent at this stage may cause reduction in cell size and number. Following may manifest this

Incidence of congential anomalies ascribed due to different tertogenic agents in England.

Route and length of administeration.

Frequency and severity are related with blood levels of different agents. If these can be kept low, then, tertogenicity becomes less omnious.

Relevant timing and specific pathology.

Teratogenic Agents.

Radiation

Dose and time of exposure are predictive of microcephaly, mental retardation, and growth retardation. Retrospective studies have demonstrated following relationship.

2-4 weeks: Spontaneous abortion or normal foetus.

4-12 weeks: Microcephaly, Menatal retardation, Cataracts, Growth retardation, Microphalanxia.

6-12 weeks: Mental and or growth retardation.

After 20 weeks effects are same as in postnatal exposures. Such as Hair loss, Skin lesions, bone marrow suppression.

Infections

Infections in first trimester have proven record of causing congenital malformations. Rubella, cytomegalovirus, Herpez Simplex, Herpez Zoster, Mumps and syphililus need proper evaluation of foetus and newborns for congenital abnormalities.

Hyperthermia

Studies suggest that sustained temperatures rather than spiking fevers, above 38.9 C (103 F) between 4-14 weeks of Gestation are teratogenic. Malformations should be scanned in first trimester.

Maternal medical disorders.

Diabetes in the mother is associated with risks of cardiac abnormalities, GI malformations and neural tube defects. Skeletal malformations can also occur.

Glycoselated Haemoglobins more than 8 % are teratogenic. Alpha-fetoprotein screening should be done at 16 weeks.

Extensive anatomic survey should be carried at 18-22 weeks to map possible malformations.

Mothers on epileptic drugs are prone to have congenital malformed foetus.

Drugs.

Drugs are divided into many categories.

  1. Starting with drugs which are absolutely safe. Vitamins and Iron.

  2. Which have produced negative effects in animals but not in humans. Penicillin, Digoxin, Epinepherine, terbutaline.

  3. Teratogenic effects in animals but no studies carried out in humans, e.g., Frusamide, Calcium blockers, Beta-Blockers.

  4. Teratogenic effects in humans but drug has to be used, e.g Phenytoin.

  1. Then lastly those drugs which have definite tetartogenic effects in humans and can be avoided certainly.like Vit A,Alcohal,Caffiene,sex steroids,

Dose threshhold: It is a theoretical dose for each teratogenic agent, below, which it is supposed to be safe.

Menopause.

Defenition: Amenorrhoea for 6-12 months in women of 45 years and elderly.

Any bleeding after this kind of amenorrhoea is usually due to some kind of pathology. Usually Polyps or Neoplasia.

Premature Menopause: Permanent amenorrhoea before 35 years of age. Causes may be

Clinical manifestations of Menopause.

These are usually multiple, affecting many systems at one time,vague ,ill defined.Can be broadly classified into

Vasomotor Symptoms.

Episodes of hot flushes and sweating lasting for few seconds to few minutes. Feeling of heat on face or/and neck once or more frequently daily. After the attack patient can become pale and sweating on the forehead may be there. These flushes may start when periods are still regular. These usually improve gradually over few months. May last for more than 5 years. Flushes appear more severe and frequent at night or at times of stress.

Mood swings.

Menopausal syndrome includes a variety of symptoms such as fatigue, headache, nervousness, loss of libido, insomnia, depression, irritability, palpitation and joint and muscle pains.

Altered menstrual functions.

Any kind of bleeding irregularity may be present. But any bleeding after amenorrhoea of 12 months must be investigated. This is very very suspect.

GIT symptoms.

Icreased or decreased appetite leading to weight changes. Indigestion and constipation are regular complaints. Retrosternal and epigastric burning can be present.

Atrophic changes.

Osteoporosis

Primary Oteoporosis is most common variety. It can be further classified as postmenopausal and senile Osteoporosis.

Defined as low bone mass with ratio of mineral to osteod tissue. It is an abnormal decrease in bone mass. But Bone is of normal structure.

Osteoporosis affects about one third of postmenopausal women. Imagine the total number in your practice.

In the absence of estrogen bone resorption takes place. Predominently trabecular bone is last. In contrast to this in senile Osteoporosis both cortical and trabecular bone is lost with increased risk of hip and vertebral fracture.

Becomes clinically manifest 10 years after menopause. Peak incidence is in 60s and early 70s.

Followoing Secondary Causes should be kept in mind

Clinical manifestation of Osteoporosis.

Investigations.

Plain xray changes (Characteristic wedge and crush fractures in spine) become evident only when upto 40 % of bone mass resorbed. Dual or Single photon absorptiometry, and quantitative CT scan can be ordered. Bone Biopsy can finalize the diagnosis in difficult cases.

Serum calcium, Phosphate and alkaline phosphate can be measured. These ar normal in primary (menopausal and senile) osteoporosis. Abnormal in secondary types.

Prevention of posts menopausal Osteoporosis.

No therapy fully restores the lost bone. So prevention is essential. Estrogen replacement therapy is the only choice. All patients with premature menopause (idiopathic and oopherectomy etc) must receive estrogen. In other women risks and benefits should be weighed. Benefits far outweigh the risks.

Patient should be educated to correct the possible risk factors for Osteoporosis.These are excerise, withdrawal of steriods, and improved diet.

Treatment of Established Osteoporosis.

HRT (Hormone replacement therapy)

Prof Dr Furrukh Zaman stressed in his interview that HRT is being grossly underused even in developed counteries. Only 12 % of women who need HRT are using it. Situation in Pakistan is certainly worse than this.

Ectopic pregnancy

J I Tay, lecturer,  J Moore, research fellow,  J J Walker, professor.  Division of Obstetrics and Gynaecology, St James's University Hospital, Leeds LS9 7TF

Ectopic pregnancy causes major maternal morbidity and mortality, with pregnancy loss, and its incidence is increasing worldwide. In northern Europe between 1976 and 1993 the incidence increased from 11.2 to 18.8 per 1000 pregnancies. In 1989 in the United States admissions to hospital for ectopic pregnancy increased from 17 800 in 1970 to 88 400.These changes were greatest in women over 35 years of age. In the United Kingdom there are around 11 000 cases of ectopic pregnancy per year (incidence 11.5 per 1000 pregnancies), with four deaths (a rate of 0.4 per 1000 ectopic pregnancies).

The incidence of ectopic pregnancy is increasing, mainly due to the increased incidence of pelvic inflammatory disease caused by Chlamydia trachomatis

Ectopic pregnancy must be excluded in a sexually active woman with a positive pregnancy test, abdominal pain, and vaginal bleeding

Early ultrasonography should be available in subsequent pregnancies for women who have had an ectopic pregnancy

Diagnosis cannot be made clinically or in the community

Treatment should be tailored to individual needs; in selected cases medical management can be as effective as laparoscopic salpingostomy

Conservative surgery results in slightly higher rates of intrauterine pregnancy and higher recurrent ectopic pregnancies

We review the incidence, causes, diagnosis, and management of ectopic pregnancy. The evidence presented is from a combination of selected published papers identified from Medline and a reflection of clinical practice in our unit. Medline was searched with the term "ectopic pregnancy" and combined with terms such as incidence, risk factors, methotrexate, salpingectomy, salpingostomy, etc.

Although a proportion of women with ectopic pregnancy have no identifiable causal factors, the risk is increased by several factors: If there is previous ectopic pregnancy, tubal damage from infection or surgery, a history of infertility, treatment for in vitro fertilisation, increased age, and smoking.

A history of pelvic inflammatory disease is particularly important and has been implicated in the increased incidence of ectopic pregnancy. After acute salpingitis, the risk of an ectopic pregnancy is increased sevenfold. This is particularly true of Chlamydia trachomatis, the main cause of pelvic inflammatory disease in the United Kingdom.Comprehensive programmes to prevent chlamydia not only decrease the incidence of C trachomatis infections but also the rate of ectopic pregnancies.

Previous female sterilisation and current use of an intrauterine contraceptive device are only risk factors when patients with ectopic pregnancy are compared with pregnant controls and not with non-pregnant women. This is because overall the risk of pregnancy in these situations is low, but if pregnancy does occur an ectopic pregnancy is more likely. The risk of ectopic pregnancy after sterilisation is only 7.3 per 1000 within 10 years.

The incidence of ectopic pregnancy after assisted reproductive techniques is 4%, which is 2-3 times greater than the background incidence. The main risk factor in this group is tubal infertility. The incidence of heterotopic pregnancy (an ectopic pregnancy together with an intrauterine pregnancy) is also increased after assisted reproductive techniques.

Ectopic pregnancies usually present after seven (SD two) weeks of amenorrhoea. The diagnosis can be difficult unless the condition is suspected and can be confused with miscarriage, an ovarian accident, or pelvic inflammatory disease. The abdominal pain is usually lateral. However, history and physical examination alone do not reliably diagnose or exclude ectopic pregnancy, as up to 9% of women report no pain and 36% lack adnexal tenderness. The presence of known risk factors can increase suspicion, but any sexually active woman presenting with abdominal pain and vaginal bleeding after an interval of amenorrhoea has an ectopic pregnancy until proved otherwise. Women who present in a collapsed state usually have had prodromal symptoms that have been overlooked. Tubal rupture is rarely sudden since it is due to invasion by the trophoblast. Therefore, if there is any suspicion, hospital referral for investigation is mandatory.

Percentage occurrence of history and presenting signs with ectopic

Referral should preferably be to a unit dedicated to managing problems early in pregnancy as this allows ease of investigations and continuity of outpatient care. The initial investigations are a sensitive pregnancy test and ultrasonography. The presence of an intrauterine pregnancy generally excludes ectopic pregnancy, although other ultrasound findings have to be considered, especially if symptoms are atypical, severe, or persistent. The use of quantitative measurement of serum concentrations of beta human chorionic gonadotrophin together with transvaginal ultrasonography has improved the diagnosis. There is, however, controversy about the concentration of serum human chorionic gonadotrophin that is diagnostic. In the presence of an ectopic mass or fluid in the pouch of Douglas, a cut off point for a serum concentration of human chorionic gonadotrophin of 1500 IU/l is recommended, but in the absence of any ultrasound signs the higher concentration of 2000 IU/l should be the cut off point before an ectopic pregnancy is diagnosed. Ectopic pregnancies produce lower concentrations of human chorionic gonadotrophin than normal pregnancies, but the change in concentrations provides more information. In a normal pregnancy, serum concentrations of human chorionic gonadotrophin double every 2-3.5 days in the fourth to eighth week of gestation reaching a peak around the eighth to 12th week, as calculated from the last menstrual period .A failure of this increase is suggestive of an ectopic pregnancy although it is also associated with early pregnancy failure. A two-day sampling interval has been recommended if paired serum samples be being tested. The accurate diagnosis of ectopic pregnancy can be life saving, reduce invasive investigations, and allow conservative treatment.

Expectant and medical management is possible, and should be considered in selected cases, but they are not widely practised in the United Kingdom. Surgery remains the mainstay of treatment, possibly overtreating a number of cases.

Expectant Management.

Some ectopic pregnancies resolve spontaneously, and expectant management is possible in selected cases. This is not related to the size of the ectopic pregnancy on an ultrasonogram but the initial serum titre of human chorionic gonadotrophin and the trend in titres are independent predictors of success. It is important, therefore, to serially monitor serum titres of human chorionic gonadotrophin in-patients who are being managed expectantly. The higher the serum concentration the more likely expectant management will fail. Overall, if the initial serum concentration of human chorionic gonadotrophin is less than 1000 IU/l, expectant management is successful in up to 88% of patients.

Medical Management.

Methotrexate, a folic acid antagonist, is used for medical management in-patients before rupture who are haemodynamically stable. It can be given intramuscularly or injected into the ectopic pregnancy, a route that delivers high concentrations locally with smaller systemic distribution. However, rates of successful treatment are lower than with systemic methotrexate, and it requires a laparoscopic or ultrasound guided needle procedure. Methotrexate in a single dose is more convenient than the variable dose regimen but may carry a higher risk of persistent ectopic pregnancy. Close follow up with serial measurements of serum concentrations of human chorionic gonadotrophin is required. A second course of treatment may be necessary, and some patients may require surgical intervention. Methotrexate treatment may produce significant side effects.

Surgical Management.

Surgical treatments may be radical (salpingectomy) or conservative (usually salpingostomy), and laparoscopy or laparotomy may perform them. Salpingectomy is the treatment of choice if the fallopian tube is extensively diseased or damaged as there is a high risk of recurrent ectopic pregnancy in that tube.

Generally, hospital stay (1.3 days) and convalescence (2.4 weeks) are shorter after laparoscopy than with laparotomy (3.1 days and 4.6 weeks respectively). Both techniques produce similar rates of complications and persistent trophoblast. If there is a risk of persistent trophoblast, follow up with serial measurements of serum concentrations of human chorionic gonadotrophin is necessary. Since no single postoperative concentration of human chorionic gonadotrophin is predictive, follow up until complete resolution is necessary. The need for a second laparoscopy should be based on symptoms rather than changes in concentrations of human chorionic gonadotrophin. In a randomised controlled trial, methotrexate and laparoscopic salpingostomy were equally effective.

The cost of salpingostomy is slightly more than salpingectomy in the short termed. Both treatments are equally effective initially, but additional treatment for persistent ectopic pregnancies is occasionally required after salpingostomy. Although it is comparatively simple to cost the acute episode, calculating the long term costs of subsequent infertility treatment and treatment for recurrent ectopic pregnancy is more difficult.

The psychological cost is often overlooked, as it is not generally viewed in the same way as other pregnancy loss. It would seem that the women have similar grief reactions to those with miscarriages but have the additional trauma of the potential reduction in fertility. Support networks such as the Miscarriage Association are recommended to women after miscarriage but, until recently, there has been no specific support group for woman after ectopic pregnancy. The recently formed Ectopic Pregnancy Trust evolved out of this need and provides both information and support.

Rates of intrauterine pregnancy after expectant management are comparable to those achieved after medical or surgical management, varying between 80% and 88%, and rates for recurrent ectopic pregnancy vary between 4.2% and 5%.

A population based cohort study reported a pregnancy rate of 66% regardless of whether treatment was surgical or medical.33 of those who conceived, 90% achieved an intrauterine pregnancy and 10% had recurrent ectopic pregnancy. The risk factors for recurrent ectopic pregnancy are previous spontaneous miscarriage, tubal damage, and age greater than 30.25 after methotrexate, between 62% and 70% of women had a subsequent intrauterine pregnancy and around 8%
