Paediatrics and geriatrics

Station 67 Child immunisation programme 185

That having been said, they are still very common in some other countries, from where they may be

reintroduced to unvaccinated children in the UK. Vaccines can and often do have side-effects, but

these are usually very mild. They include redness and swelling at the injection site, flu-like symptoms,

and a fever. Some vaccines are given together in a single injection so as to minimise the number of

injections required and to prevent delayed or missed vaccinations. There is no added benefit to giving

them separately.

The MMR controversy

Measles can cause pneumonia, fits, encephalitis, sub-acute sclerosing panencephalitis, and

death.

Mumps can cause meningitis, encephalitis, deafness, and sterility.

Rubella in pregnancy can cause severe damage to the foetus.

The MMR vaccine is safe and effective, and more than 500 million doses of the vaccine have

been given since 1972.

Common side-effects of the MMR vaccine are a sore injection site and flu-like symptoms. Very

rarely, an allergic reaction can occur.

There is no evidence to support a distinct syndrome of MMR-induced autism or inflammatory

bowel disease.

Separate administration of the measles, mumps, and rubella vaccines provides no added

benefit over administration of the combined MMR vaccine, but means three injections and

potentially delayed or missed vaccinations.

Geriatric history

Before starting

Introduce yourself to the patient and confirm his name and date of birth.

Explain that you are going to ask him some questions to determine the nature of his problems,

and obtain consent.

Ensure that he is comfortable.

If he has glasses or a hearing aid, ensure that these are being worn.

If appropriate, ask if you can take a collateral history from a carer.

The history

Presenting complaint

Enquire about the patient’s presenting complaint, if any. Use open questions and active listening.

Explore any symptoms, e.g. onset, duration, previous episodes, pain, associated symptoms.

Enquire about the effects that his symptoms are having on his everyday life.

Elicit his ideas, concerns, and expectations.

[Note] Elderly patients may attribute symptoms to normal ageing and may not offer them unless specifically asked.

Then aim to cover:

Physical independence, e.g. describe a typical day.

Functional assessment: can he stand up and walk, climb the stairs, get on and off the toilet, get

in and out of the bathtub, dress, cook/clean/shop, and manage his finances and administration?

Daily diet, including nausea, vomiting, and change in appetite or weight.

Urinary and faecal incontinence.

Mood (e.g. “How are you keeping in your spirits?”). Also ask about sleep and appetite.

Memory and cognitive impairment.

Dizziness/falls (see Station 31: History of ‘funny turns’).

Vision (corrective aids, accidents, difficulty reading, feeding, dressing, grooming, driving, and

recognising pills or items).

Past medical history

Social interaction: family, friends, clubs, etc. If appropriate, ask, “Who will help you if you become

ill?” and, “Who should make decisions for you if you become too ill to speak for yourself?”

After taking the history

Ask the patient if there is anything that he might add that you have forgotten to ask about.

Ask if he has any questions or concerns.

Thank him.

Indicate that you would like to examine the patient and order some investigations.

Formulate a problem list and suggest treatment options.

189Obstetrics, gynaecology, and sexual health

Station 70

Obstetric history

Specifications: You may be asked to focus on only a certain aspect or certain aspects of the obstetric

history.

Before starting

Introduce yourself to the patient, and confirm her name and date of birth.

Explain that you are going to ask her some questions to uncover the nature and background of

her obstetric complaint, and obtain consent.

Ensure that she is comfortable.

The history

Presenting problem (presenting complaint)

Ask about the presenting problem (if any) in some detail, e.g. onset, duration, pain, bleeding, associated

symptoms, previous occurrences.

History of the present pregnancy

Determine the duration of gestation and calculate the expected due date (EDD).

– ask about the date of the patient’s last menstrual period (LMP)

– ask if her periods had been regular prior to her LMP

– ask if she had been on the oral contraceptive pill (OCP): if yes, determine when she stopped

taking it and the number of periods she had before becoming pregnant

– determine the duration of gestation and calculate the EDD (to calculate the EDD, add 9

months and 7 days to the date of the LMP)

Ask about foetal movements and, if present, about any changes in their frequency.

Take a detailed history of the pregnancy, enquiring about:

First trimester

– date and method of pregnancy confirmation

– was the pregnancy planned or unplanned? If it was unplanned, is it desired?

– symptoms of pregnancy (e.g. sickness, indigestion, headaches, dizziness…)

– bleeding during pregnancy

– ultrasound scan (10–12/52)

– chorionic villus sampling (10–13/52)

– type of antenatal care (e.g. shared care, midwife-led care, domino scheme, consultant-led

scheme)

Second trimester

– amniocentesis (16–18/52)

– anomaly scan (18–20/52)

– quickening (16–18/52)


Clinical Skills for OSCEs

190 Station 70 Obstetric history

Third trimester

– antenatal clinic findings – you must ask about blood pressure and proteinuria

– vaginal bleeding

History of previous pregnancies (past reproductive history)

Ask the patient if she has had any previous pregnancies.

For each previous pregnancy, ask about:

The pregnancy, including

– the date (year) of birth

– the duration of the pregnancy and any problems e.g. placenta praevia, abruption, preeclampsia

– the mode of delivery and any problems e.g. ventouse or forceps delivery

– the outcome

The child, including

– birth weight

After taking the history

Ask the patient if there is anything she might add that you have forgotten to ask about.

Thank the patient.

If asked, summarise your findings and offer a differential diagnosis.

Conditions most likely to come up in an obstetric history station

Ectopic pregnancy

In about 1% of pregnancies the fertilised egg implants outside the uterine cavity, most often

in the Fallopian tube, but also in the cervix, ovaries, and abdomen. Clinical presentation occurs

at a mean of about 7 weeks after the LMP, with a range of 5–8 weeks. Symptoms principally

involve lower abdominal pain which may be worse upon moving and straining, and vaginal

and internal bleeding which can be life-threatening. The principal differential is from normal

pregnancy and miscarriage.

Miscarriage

In about 15–20% of all recognised pregnancies, the pregnancy ends spontaneously at a stage

when the embryo or foetus is incapable of surviving (before approximately 20–22 weeks

of gestation, although most miscarriages occur prior to 13 weeks of gestation). The most

common symptoms, which can range from very mild to severe, are cramping and vaginal

bleeding with blood clots. The principal differential is from ectopic pregnancy.

Placenta praevia

In about 0.5% of pregnancies, usually during the second or third trimester, the placenta

attaches to the uterine wall close to or covering the cervix. This classically leads to painless,

bright red vaginal bleeding that increases in frequency and intensity over a period of weeks.

Placental abruption

In about 1% of pregnancies the placenta partially or completely separates from the uterus,

depriving the baby of oxygen and nutrients and causing heavy bleeding in the mother.

Placental abruption can begin at any time after 20 weeks of gestation, classically with variable

amounts of vaginal bleeding, abdominal pain, back pain, uterine tenderness and contraction,

and rapid and repetitive uterine contractions.

False labour (Braxton Hicks contractions)

Normal pregnancy


Clinical Skills for OSCEs

192 Station 71

Obstetric examination

Specifications: Most likely an anatomical model in lieu of a patient.

Before examining the patient

Introduce yourself to the patient, and confirm her name and date of birth.

Explain the examination and obtain consent.

Indicate that you would weigh the patient, take her blood pressure (pre-eclampsia), dipstick her

urine (pre-eclampsia, gestational diabetes) and ask her to empty her bladder.

Position the patient so that she is lying supine (she can sit up if she finds lying supine uncomfortable).

Ask her to expose her abdomen.

Ensure that she is comfortable.

The examination

General inspection

Carry out a general inspection from the end of the couch.

Inspection of the abdomen

Abdominal distension and symmetry. Is the umbilicus everted?

Foetal movements (after 24 weeks).

Linea nigra (brownish streak running vertically along the midline from the umbilicus to the

pubis).

Striae gravidarum (purplish stretch marks from the current pregnancy).

Striae albicans (silvery stretch marks from previous pregnancies).

Scars.

Palpation of the abdomen

Enquire about pain before palpating the abdomen.

Then, facing the mother, determine the:

– size of the uterus

– liquor volume (normal, polyhydramnios, oligohydramnios)

– number of foetuses

– size of the foetus(es)

– lie

– presenting part

Turning to face the mother’s feet, determine the:

– engagement


Obstetrics, gynaecology, and sexual health

Station 71 Obstetric examination 193

Table 27. Some important obstetric definitions

Lie. The relationship of the long axis of the foetus to that of the uterus, described as longitudinal,

transverse, or oblique.

Presenting part. The part of the foetus that is in relation with the pelvic inlet, e.g. cephalic/breech for

a longitudinal lie or shoulder/arm for a transverse/oblique lie.

Engagement. During engagement, the presenting part descends into the pelvic inlet in readiness for

labour. Engagement is usually described in fifths of head palpable above the pelvic inlet, although

sometimes the presenting part may not be the head. Engagement usually occurs after 37 weeks of

gestation, before which the foetus is said to be ‘floating’ or ‘ballotable’.

Although not usually performed until labour, indicate that you could also determine the position,

station, and attitude of the foetus. Position refers to the relationship of a point of reference on the

foetus to the quadranted pelvis; station (see Figure 43) refers to the depth of the presenting part in

relation to the ischial spines (from -5 to +5); attitude refers to the degree of flexion of the foetus’ body

parts.

Figure 43. Measurement of station.

Symphyseal–fundal height (SFH)

Using a tape measure, measure from the mid-point of the symphysis pubis to the top of the uterus.

From 20 to 38 weeks of gestation, the SFH in centimetres approximates to the number of weeks of

gestation ± 2 (see Figure 44).

Auscultation

Listen to the foetal heart by placing a Pinard stethoscope over the foetus’ anterior shoulder and

estimate the heart rate (usually 110–160 bpm). Ensure that your hands are free from the abdomen.

Gynaecological history

Specifications: You may be asked to circumscribe your questioning to certain aspects of the

gynaecological history only.

Before starting

Introduce yourself to the patient, and confirm her name and date of birth.

Explain that you are going to ask her some questions to uncover the nature and background of

her gynaecological complaint, and obtain consent.

Ensure that she is comfortable.

The history

Presenting complaint and history of presenting complaint

Ask about the presenting problems (if any) in some detail, e.g. onset, duration, pain, bleeding,

associated symptoms, previous occurrences. Explore the patient’s ideas, concerns and expectations (ICE). Then use the mnemonic ‘MOSS’ to ask about:

• Menstruation:

– age at menarche

– regularity of the menses

– dysmenorrhoea

– date of LMP – did it seem normal?

– inter-menstrual, post-menopausal, post-coital bleeding

• Obstetric history

• Sexual/Smear:

– coitus, e.g. “Are you sexually active?” “When was the last time you had sexual intercourse?”

– dyspareunia

– use of contraception

– date and result of the last cervical smear test

• Symptoms:

– vaginal discharge – for any discharge, ask about amount, colour, smell, itchiness

– vaginal prolapse

– urinary incontinence

Past medical history

Past gynaecological history.

Past reproductive history: previous pregnancies in chronological order, including terminations

and miscarriages.

Past medical history:

– current, past, and childhood illnesses

– surgery

– recent visits to the doctor

196 Station 72 Gynaecological history

Drug history

Prescribed medication, including, if appropriate, oral contraceptives and HRT.

Over-the-counter medication.

Recreational drug use.

Allergies.

Family history

Ask about parents, siblings, children. Has anyone in the family had a similar problem? In the

case of a suspected STD, don’t forget to ask about the partner.

Social history

Employment.

Housing and home-help.

Travel.

Smoking.

Alcohol use.

After taking the history

Ask the patient if there is anything she might add that you have forgotten to ask about.

Thank the patient.

Summarise your findings and offer a differential diagnosis.

Conditions most likely to come up in a gynaecological history station

Menopause

The permanent cessation of the primary functions of the ovaries, namely, the ripening and

release of ova and the release of hormones that cause both the creation and the subsequent

shedding of the uterine lining. It normally occurs gradually over a period of years during the

late 40s or early 50s.

Signs and symptoms may include irregular menses, hot flushes and night sweats, increased

stress, mood changes, sleep disturbances, atrophy of genitourinary tissue, vaginal dryness, and

breast tenderness.

Amenorrhoea

The absence of a menstrual period in a pre-menopausal woman for a period of 3 months (or 9

months in women with a history of oligomenorrhoea). It is a sign with many causes including

normal pregnancy, lactation, and oral contraceptives.

Primary amenorrhoea (menstruation has not started by age 16 or age 14 if there is a lack

of secondary sexual characteristics) is often related to chromosomal or developmental

abnormalities.

Secondary amenorrhoea (menstruation has started but then stops) is often related to

disturbances in the hypothalamo–pituitary axis due to, for example, stress, excessive dieting or

exercising, PCOS, or a prolactin-secreting pituitary tumour; hypothyroidism; certain drugs such

as antipsychotics and corticosteroids; intrauterine scar formation; premature menopause.


Obstetrics, gynaecology, and sexual health

Station 72 Gynaecological history 197

Dysmenorrhoea

Severe uterine pain possibly radiating to the back and thighs either preceding menstruation

by several days or accompanying it. Associated symptoms might include menorrhagia, nausea

and vomiting, diarrhoea, headache, dizziness, fainting, and fatigue.

Secondary dysmenorrhoea is diagnosed in the presence of an underlying cause, commonly

endometriosis or uterine fibroids.

Menorrhagia

Abnormally heavy (>80 ml) and/or prolonged (>7 days) menstrual period at regular intervals

possibly associated with dysmenorrhoea and signs and symptoms of anaemia. In many

cases, no cause can be found. However, common causes include hormonal imbalance, pelvic

inflammatory disease, endometriosis, uterine polyps or fibroids, adenomyosis, intrauterine

device, coagulopathy, and certain drugs such as NSAIDs and anticoagulants.

Inter-menstrual bleeding

Bleeding between periods may be associated with sexual intercourse or may occur

spontaneously. Causes of spontaneous inter-menstrual bleeding include physiological

hormone fluctuations, oral contraceptives, cervical smear test, certain drugs such as

anticoagulants and corticosteroids, vaginitis, infection (e.g. chlamydia), cervicitis, cervical

polyps, uterine polyps or fibroids, and adenomyosis. It is particularly important to consider

cervical cancer, endometrial adenocarcinoma, threatened miscarriage, and ectopic pregnancy.

Vaginal discharge (see Station 77)

Dyspareunia (see Station 77)

198 Station 73

Gynaecological (bimanual) examination

Specifications: A pelvic model in lieu of a patient.

Before starting

Introduce yourself to the patient, and confirm her name and date of birth.

Explain the examination, reassuring the patient that, although it may feel uncomfortable, it

should not cause any pain.

Obtain consent.

Ask for a female chaperone.

Confirm that the patient has emptied her bladder.

Indicate that you would normally carry out an abdominal examination prior to a gynaecological

examination.

Once undressed, ask the patient to lie flat on the couch, bringing her heels to her buttocks and

then letting her knees flop out.

Ensure that she is comfortable, specifically enquiring about any areas of pain, and cover her up

with a drape.

The examination

Always tell the patient what you are about to do.

Don a pair of non-sterile gloves and adjust the light source to ensure maximum visibility.

Inspect the vulva, paying close attention to the pattern of hair distribution, the labia majora,

and the clitoris. Note any redness, ulceration, masses, or prolapse.

Inspect the perineum, looking for episiotomy scars or perineal tears (fine white lines).

Palpate the labia majora for any masses.

Try to palpate Bartholin’s gland (the structure is not normally palpable).

Lubricate the index and middle fingers of your gloved right hand.

Use the thumb and index finger of your left hand to separate the labia minora.

Insert the index and middle fingers of your right hand into the vagina at an angle of 45 degrees.

Palpate the vaginal walls for any masses and for tenderness.

Use your fingertips to palpate the cervix. Assess the cervix for size, shape, consistency, and

mobility. Is the cervix tender? Is it open?

Palpate the uterus: place the palmar surface of your left hand about 5 cm above the symphysis

pubis and the internal fingers of your right hand behind the cervix and gently try to appose

your fingers in an attempt to ‘catch’ the uterus. Assess the uterus for size, position, consistency,

mobility, and tenderness. Can you feel any masses?


Obstetrics, gynaecology, and sexual health

Station 73 Gynaecological (bimanual) examination 199

Palpate the right adnexae: place the palmar surface of your left hand in the right iliac fossa and

the internal fingers of your right hand in the right fornix and gently try to appose your fingers

in an attempt to ‘catch’ the ovary. Assess the ovary for any masses and for excitation tenderness

(look at the patient’s face).

Use a similar technique for palpating the left adnexae.

Once you have removed your internal fingers, inspect the glove for any blood or discharge.

After the examination

Dispose of the gloves and wash your hands.

Offer the patient a box of tissues and give her the opportunity to dress.

Thank the patient.

Ensure that she is comfortable.

Indicate that you could also have carried out a speculum examination and taken a cervical

smear (see Station 74: Speculum examination and liquid based cytology test).

Summarise your findings and offer a differential diagnosis.

Conditions most likely to come up in a gynaecological examination station

Uterine fibroids

Common and often multiple benign tumour of the smooth muscle (myometrium) of the

uterus, typically found during the middle and later reproductive years. In most cases uterine

fibroids are asymptomatic, but in some cases they can cause menorrhagia, dysmenorrhoea,

inter-menstrual bleeding, dyspareunia, urinary frequency and urgency, and fertility problems.

Ovarian cyst

Functional fluid-filled sacs within or on the surface of an ovary. Ovarian cysts are very

common, particularly in women of reproductive age, and are generally benign and

asymptomatic. Symptoms can include pelvic pain, pain during urination, defecation, or sexual

intercourse, urinary frequency, nausea and vomiting, abdominal fullness, breast tenderness,

and menstrual irregularities.

Speculum examination and

liquid based cytology test

Specifications: An anatomical model in lieu of a patient.

Before starting

Introduce yourself to the patient, and confirm her name and date of birth.

Explain the procedure, specifying that it may be uncomfortable but should not be painful.

Obtain consent.

Ask for a female chaperone.

Gather the appropriate equipment.

Confirm that the patient has emptied her bladder.

Once undressed (from the waist down), ask her to lie flat on the couch, bringing her heels to her

buttocks and then letting her knees flop out.

Ensure that she is comfortable, and cover her up with a drape.

The equipment

On a trolley, gather:

Non-sterile gloves Lubricant (K-Y jelly)

Bivalve (Cusco) speculum Cervical brush

Pot of preservative solution

The procedure

Verify the expiry date on the pot and indicate that you would label it, together with the cytology request form, with the patient’s name, date of birth, and hospital number.

Adjust the light source to ensure maximum visibility.

Wash your hands and don the gloves.

Inspect the vulva, paying close attention to the pattern of hair distribution, the labia majora,

and the clitoris. Note any redness, ulceration, masses, or prolapse.

Warm the speculum’s blades in your palm or under warm water (unnecessary with plastic

blades).

Place a small amount of K-Y jelly on either side of the speculum near the tip.

Tell the patient that you are about to start, and ask her to relax and take deep breaths.

With your non-dominant hand, part the labia to ensure all hair and skin are out of the way.

With your other hand, slowly and gently insert the speculum with the screw facing sideways,

rotating it into position (screw upwards) and then opening it.

Place the back of your non-dominant hand against her pubic area and gently open the speculum to identify the cervix.

Fix the speculum in the open position by tightening the screw.

A smear should not be taken if there is any bleeding or vaginal discharge.

Insert the central bristles of the cervical brush into the endocervical canal and rotate it by 360

degrees in a clockwise direction five times.
