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’).

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

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

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)


Clinical Skills for OSCEs

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.

Paediatrics and geriatrics

Station 62 Paediatric examination: cardiovascular system 171

Chest examination

Auscultate the bases of the lungs and check for sacral oedema.

Abdominal examination

Palpate the abdomen to exclude ascites and/or an enlarged liver (congestive heart failure). Note that

the liver edge can usually be palpated in younger infants.

Peripheral pulses

Feel the temperature of the feet, palpate the femoral pulses, and check for pedal oedema.

After the examination

Cover the child.

Ask the child and parent if they have any questions or concerns.

Thank the child and parent.

Indicate that you would test the urine, examine the retina with an ophthalmoscope and, if

appropriate, order some key investigations, e.g. a CXR, ECG, echocardiogram.

Summarise your findings and offer a differential diagnosis.

Conditions most likely to come up in a paediatric cardiovascular examination station

Ventricular septal defect (VSD)

Pansystolic murmur best heard over the left lower sternal edge and possibly accompanied

by a palpable thrill, parasternal heave, and displaced apex beat. Most VSDs are small and

asymptomatic and may close spontaneously within the first year of life. However, a large VSD

may progressively lead to higher pulmonary resistance and, finally, to irreversible pulmonary

vascular changes, producing the so-called Eisenmenger syndrome (reversal of shunt to rightto-left shunt). Eisenmenger syndrome can also result from atrial septal defect and patent

ductus arteriosus.

Patent ductus arteriosus (PDA)

Continuous machine-like murmur best heard over the pulmonary area and possibly

accompanied by a left subclavicular thrill, displaced apex beat, and collapsing pulse. The first

heart sound is normal but the second is often obscured by the murmur. The ductus arteriosus

is a shunt that runs from the pulmonary artery to the descending aorta and which enables

blood to bypass the closed lungs in utero. A small PDA may cause no signs or symptoms and

may go undetected into adulthood, but a large one can cause signs and symptoms of heart

failure soon after birth.

Atrial septal defect

Ejection systolic murmur best heard in the pulmonary area due to increased blood flow across

the pulmonary valve with an associated mid-diastolic murmur best heard in the tricuspid area

due to increased blood flow across the tricuspid valve. These murmurs, neither of which is

particularly loud, are accompanied by a wide fixed splitting of the second heart sound (S2

) and

a displaced apex beat. The patient is often asymptomatic.


Clinical Skills for OSCEs

172 Station 62 Paediatric examination: cardiovascular system

Pulmonary stenosis

Loud ejection systolic murmur with an ejection click that is best heard in the pulmonary area.

This murmur may be accompanied by a widely split second heart sound, and by a systolic

thrill and parasternal heave. The patient is often asymptomatic.

Aortic stenosis

Ejection systolic murmur with an ejection click best heard in the aortic area and radiating to

the carotids. The murmur may be accompanied by a slow-rising pulse and a heaving cardiac

apex. The patient is often asymptomatic.

Coarctation of the aorta

Arterial hypertension in the right arm with normal to low blood pressure in the legs. There is

radio-femoral delay between the right arm and the femoral artery and, in severe cases, a weak

or absent femoral artery pulse. In contrast, mild cases may go undetected into adulthood.

Tetralogy of Fallot

The tetralogy refers to VSD, pulmonary stenosis, overriding aorta, and right ventricular

hypertrophy, and there may also be other anatomical abnormalities. There is cyanosis from

birth or developing in the first year of life.


173Paediatrics and geriatrics

Station 63

Paediatric examination: respiratory system

Read in conjunction with Station 17.

If you are asked to examine the respiratory system of a younger child (an unlikely event), be prepared

to change the order of your examination and to modify your technique as appropriate. For example,

you may need to examine the child on his parent’s knees or auscultate his chest as soon as he stops

crying. As in all paediatric stations, the quality of your rapport with the child will be of considerable

importance.

Before starting

Introduce yourself to the child and parent, and confirm the child’s name and date of birth.

Explain the examination and ask for consent to carry it out.

Position the child at 45 degrees, and ask him to remove his top(s).

Ensure that he is comfortable.

The examination

General inspection

From the end of the couch inspect the child carefully, looking for any obvious abnormalities in

his general appearance.

Does the child look his age? Ask to look at the growth chart.

Is he breathless or cyanosed?

Is his breathing audible?

Note the rate, depth, and regularity of his breathing.

Look around the child for clues such as a PEFR meter, inhalers, etc.

Table 25. Normal respiratory rates in children

Age in years Respiratory rate (breaths per minute)

Premature infant 40–60

Term infant 30–50

6 years 19–24

12 years 16–21

Look for:

Deformities of the chest (barrel chest, pectus excavatum, pectus carinatum) and spine.

Asymmetry of chest expansion.

Signs of respiratory distress such as the use of accessory muscles of respiration, suprasternal, intercostal, and/or subcostal recession, nasal flaring, grunting, tracheal tug, and difficulty speaking.

Added sounds such as cough, croup, wheeze, stridor.

Harrison’s sulcus (horizontal subcostal groove; in a child, suggestive of asthma).

Operative scars.

Inspection and examination of the hands

Take both hands and assess them for colour and temperature.

Look for clubbing.


Clinical Skills for OSCEs

174 Station 63 Paediatric examination: respiratory system

Determine the rate, rhythm, and character of the radial pulse (in younger infants, the brachial

pulse).

State that you would record the blood pressure.

Inspection and examination of the head and neck

Inspect the conjunctivae for signs of anaemia.

Inspect the mouth for signs of central cyanosis.

Assess the jugular venous pressure and jugular venous pulse form.

Palpate the cervical, supraclavicular, infraclavicular, and axillary lymph nodes.

Palpation of the chest

Ask the child if he has any pain in the chest.

Palpate for tracheal deviation by placing the index and middle fingers of one hand on either

side of the trachea in the suprasternal notch. (As this may be uncomfortable, it is probably best

omitted in younger children.)

Palpate for the position of the cardiac apex.

[Note] Carry out all subsequent steps on the front of the chest and, once this is done, repeat them on the back of the

chest.

Palpate for equal chest expansion, comparing one side to the other.

Palpate for tactile fremitus.

Percussion of the chest

Percuss the chest. Start at the apex of one lung and compare one side to the other. Do not

forget to percuss over the clavicles and on the sides of the chest. Note that percussion of the

chest is not useful in young infants.

Auscultation of the chest

Warm up the diaphragm of your stethoscope.

If old enough, ask the child to take deep breaths through the mouth and, using the diaphragm

of the stethoscope, auscultate the chest. Start at the apex of one lung, and compare one side to

the other. Are the breath sounds vesicular or bronchial? Are there any added sounds?

Oedema

Assess for sacral and pedal oedema.

After the examination

Cover the child.

Ask the child and parent if they have any questions or concerns.

Thank the child and parent.

Indicate that you would like to look at the sputum pot, measure the PEFR and, if appropriate,

order some key investigations, e.g. a CXR, FBC, etc.

Summarise your findings and offer a differential diagnosis.

Station 63 Paediatric examination: respiratory system 175

Conditions most likely to come up in a paediatric respiratory examination station

Cystic fibrosis

Autosomal recessive progressive multisystem disease that is related to a mutation in the CFTR

gene and that leads to viscous secretions.

In terms of the respiratory system, findings on physical examination may include delayed

growth and development, finger clubbing, nasal polyps, recurrent chest infections, shortness

of breath, coughing with copious phlegm production, haemoptysis, hyper-inflated chest, cor

pulmonale.

Broncho-pulmonary dysplasia (BPD)

Chronic lung disorder that involves inflammation and scarring in the lungs and which is

most common among children who were born prematurely and who received prolonged

mechanical ventilation for respiratory distress syndrome.

Findings on physical examination may include delayed growth and development, shortness of

breath, crackles, wheezes and decreased breath sounds, hyper-inflated chest, cor pulmonale.

Pneumonia

Findings on physical examination may include signs of consolidation accompanied by

fever, lethargy, poor feeding, shortness of breath, productive cough, and, in some cases,

haemoptysis and pleuritic chest pain.

Asthma

Findings on physical examination may include shortness of breath, chest tightness, wheezing

and coughing, signs of respiratory distress such as the use of accessory muscles of respiration

and intercostal recession, hyper-inflated chest.

Paediatric examination: abdomen

Read in conjunction with Station 22.

Before starting

Introduce yourself to the child and parent, and confirm the child’s name and date of birth.

Explain the examination and ask for consent to carry it out.

Position the child so that he is lying flat and expose his abdomen as much as possible (customarily ‘nipples to knees’, although this is not appropriate in an OSCE setting).

Ensure that he is comfortable.

The examination

General inspection

From the end of the couch, observe the child’s general appearance:

– does the child look his age? Ask to look at the growth chart

– nutritional status

– state of health/other obvious signs

Inspect the abdomen noting any:

– distension

– localised masses

– scars and skin changes

Look around the child for clues such as oxygen, tubes, drains, etc.

A distended abdomen is often a normal finding in younger infants.

Inspection and examination of the hands

Take both hands looking for:

– temperature and colour

– clubbing (malabsorption, inflammatory bowel disease, primary biliary cirrhosis)

– nail signs

Take the pulse.

Inspection and examination of the head, neck, and upper body

Inspect the sclera and conjunctivae for signs of jaundice or anaemia.

Inspect the mouth, looking for ulcers (Crohn’s disease), angular stomatitis (nutritional deficiency), atrophic glossitis (iron deficiency, vitamin B12 deficiency, folate deficiency), furring of

the tongue (loss of appetite), and the state of the dentition.

Examine the neck for lymphadenopathy.

Palpation of the abdomen

Abdominal palpation can be difficult in children if they do not relax the abdominal muscles.

Attempt to distract the child by handing him a toy or try to make him relax by coaxing him into

palpating his abdomen and then copying his actions.


Paediatrics and geriatrics

Station 64 Paediatric examination: abdomen 177

Ask the child if he has any tummy pain and keep your eyes on his face as you begin

palpating his abdomen.

Light palpation – begin by palpating furthest from the area of pain or discomfort and systematically palpate in the four quadrants and the umbilical area. Look for tenderness, guarding, and

any masses.

Deep palpation – for greater precision. Describe and localise any masses.

Palpation of the organs

Liver – starting in the right lower quadrant, feel for the liver edge using the flat of your hand.

Note that in younger infants the liver edge is normally palpable (<1cm).

Spleen – palpate for the spleen as for the liver, starting in the right lower quadrant.

Kidneys – position the child close to the edge of the bed and ballot each kidney using the technique of deep bimanual palpation. Beyond the neonatal period, it is unlikely that you should

be able to feel a normal kidney.

Percussion

Percuss the liver area, also remembering to detect its upper border.

Percuss the suprapubic area for dullness (bladder distension).

If the abdomen is distended, test for shifting dullness (ascites).

Auscultation

Auscultate in the mid-abdomen for abdominal sounds. Listen for 30 seconds at least before

concluding that they are hyperactive, hypoactive, or absent.

Examination of the groins and genitalia

Inspect the groins for hernias and, in boys, examine the testes (this is particularly important in

younger infants).

Note that examination of the groins and genitalia may only need to be mentioned, as it is not

usually carried out in the OSCE setting.

Rectal examination

PR is not routine practice in paediatrics and should be avoided unless specifically indicated.

After the examination

Ask to test the urine.

Cover the child.

Ask the child and parent if they have any questions or concerns.

Indicate that you would test the urine and order some key investigations, e.g. ultrasound scan,

FBC, LFTs, U&Es, and clotting screen.

Thank the child and parent.

Summarise your findings and offer a differential diagnosis.


Clinical Skills for OSCEs

178 Station 64 Paediatric examination: abdomen

Conditions most likely to come up in a paediatric abdomen station

Constipation

The majority of children with constipation do not have a medical disorder causing the

constipation. Many things can contribute to constipation such as avoidance of the toilet (for

various reasons), changes in diet or poor diet, and dehydration.

Medical disorders that can cause chronic constipation include hypothyroidism, diabetes, cystic

fibrosis, and disorders of the nervous system such as cerebral palsy and mental retardation.

Constipation since birth may be from Hirschsprung disease (a.k.a. congenital aganglionic

megacolon).

Other causes of chronic constipation include depression, drug side-effects, coercive toilet

training, and sexual abuse.

Coeliac disease

An autoimmune disorder of the small intestine that occurs in genetically predisposed people

of all ages, but often from infancy. It is caused by a reaction to gliadin, a prolamin (gluten

protein) found in wheat, barley, and rye, and results in villous atrophy.

Symptoms include abdominal pain and cramping, diarrhoea, steatorrhoea, failure to thrive,

and fatigue. Signs include short stature, a distended abdomen, wasted buttocks, mouth ulcers,

and signs of anaemia.

Kidney transplant

A kidney transplant has been required as a consequence of end-stage renal failure, which

may itself have been a consequence of a birth defect, a structural malformation, a hereditary

disease such as polycystic kidney disease or Alport syndrome, a glomerular disease, or a

systemic disease such as diabetes or lupus.

Paediatric examination: gait and neurological

function

Before starting

Introduce yourself to the child and parent, and confirm the child’s name and date of birth.

Explain the examination and ask for consent to carry it out.

Ensure that he is comfortable.

Examination of neurological function in children is principally a matter of observation.

If the child is old enough to obey commands, a more formal assessment of gait and

neurological function can be carried out, as in adults.

The examination

Neurological overview

A brief developmental assessment should be performed to enable you to gauge the child’s

subsequent performance. Ask the parent the child’s age and if there are any concerns about

the child’s vision and/or hearing.

Gait and movement

If the child is too young to walk, observe him crawling or playing. Is he using all his limbs

equally?

If possible, observe the child walking and running. Common abnormalities of gait in children

include:

– scissoring or tiptoeing gait: suggestive of cerebral palsy or of Duchenne muscular dystrophy

– broad-based gait: suggestive of a cerebellar disorder

– limp: limps have many causes including dislocated hip, trauma, sepsis, and arthritis

If possible, observe the child rising from the floor. The Gower sign (the child rising from the floor

by ‘climbing’ up his legs) is suggestive of Duchenne muscular dystrophy.

Inspection

Inspect all four limbs, in particular looking for muscle wasting or hypertrophy. Hypertrophy of

the calves is suggestive of Duchenne muscular dystrophy.

Tone

Assess tone and range of movement in all four limbs.

In younger children also assess truncal tone by trying to get the child to sit unsupported.

In young infants test head lag by lying the infant supine and pulling up his upper body by the

arms.

Power

Observe the child playing, and look for appropriate anti-gravity movement. A more formal

assessment can be carried out if the child is old enough to follow instructions.

Reflexes

Check all reflexes as in the adult. In a younger child, prefer your finger to a tendon hammer.

Practice is the key!


Clinical Skills for OSCEs

180 Station 65 Paediatric examination: gait and neurological function

Note that eliciting the Babinsky sign (extensor plantar reflex) is not very discriminative

in children.

Co-ordination

If the child is old enough to carry out instructions, assess co-ordination by the finger-to-nose

test or just by asking the child to jump or hop. If the child cannot carry out instructions, give him

toys or some bricks and assess his co-ordination by observing him at play.

Sensation

Indicate that you would test sensation.

Cranial nerves

Indicate that you would test the cranial nerves – where possible this is done as in the adult.

After the examination

Thank the parent and child.

If appropriate, indicate that you would order some key investigations, e.g. CT, MRI, nerve conduction studies, electromyography, etc.

Summarise your findings and offer a differential diagnosis.

Conditions most likely to come up in a paediatric gait and neurological function station

Cerebral palsy

In most cases of cerebral palsy there is a spastic, scissoring gait. The hips, knees, and ankles

are flexed, producing a crouching and tiptoeing demeanour. In addition, the hips are

adducted and internally rotated, such that the knees cross or hit each other in a scissor-like

movement. There is a similar pattern of flexion and adduction in the upper limbs.

Duchenne muscular dystrophy

Severe recessive X-linked form of muscular dystrophy.

There is rapid progression of muscle degeneration leading to generalised and symmetrical

weakness of the proximal muscles.

Symptoms and signs include muscle wasting, pseudohypertrophy of the calves, waddling gait,

toe walking, frequent falls, poor endurance, difficulties running, jumping, or climbing stairs,

difficulties standing unaided, and positive Gower’s sign, with the child ‘walking’ his hands up

his legs to stand upright.

Myotonic dystrophy

Autosomal dominant progressive and highly variable multisystemic disease characterised by

muscle wasting, myotonia (delayed relaxation of the muscles after voluntary contraction),

cataracts, heart conduction defects, endocrine defects, and cognitive abnormalities, amongst

others.

The first muscles to be affected by wasting and weakness are typically those of the face and

neck (leading to a ‘fish face’ and ‘swan neck’ appearance), hands, forearms, and feet.

The disease commonly affects adults but it has several forms and can also present as early as

birth.

182 Station 66 Infant and child Basic Life Support

If the child responds by answering or moving:

– leave the child in the position in which you find him (provided he is not in further danger)

– check his condition and get help if needed

– reassess him regularly

If the child does not respond:

– shout for help

– turn the child onto his back and open his airway by using the head-tilt, chin-lift technique

(see Station 91); if you have difficulty opening the airway using the head-tilt, chin-lift technique, try the jaw-thrust technique (see Station 93)

If you suspect that there may have been injury to the neck, try to open the airway using

chin lift or jaw thrust alone. If this is unsuccessful, add head tilt a small amount at a time

until the airway is open.

Holding the child’s airway open, put your face close to his mouth and look along his chest.

Listen, feel, and look for breathing for no more than 10 seconds.

If the child is breathing normally:

– turn him into the recovery position

– send for help

– check for continued breathing

If he is not breathing normally or is making agonal gasps (infrequent, irregular breaths):

– carefully remove any obvious airway obstruction

– give 5 initial rescue breaths

While performing the rescue breaths, note any gag or cough response to your action.

To deliver rescue breaths to a child over 1 year:

– ensure head tilt and chin lift

– pinch the soft part of his nose closed with the index finger and thumb of the hand on his

forehead

– allow his mouth to open, but maintain chin lift

– take a breath and place your lips around his mouth, making sure that you have a good seal

– blow steadily into his mouth over 1–1.5 seconds, watching for his chest to rise

– maintaining head tilt and chin lift, take your mouth away from the victim and watch for his

chest to fall

– take another breath and repeat this sequence 4 more times

To deliver rescue breaths to an infant:

– ensure a neutral position of the head and apply chin lift

– take a breath and cover the mouth and nasal apertures of the infant with your mouth,

making sure you have a good seal

– blow steadily into the infant’s mouth and nose over 1–1.5 seconds so that the chest rises

visibly

– maintaining head tilt and chin lift, take your mouth away from the victim and watch for his

chest to fall

– take another breath and repeat this sequence 4 more times

If you have difficulty achieving an effective breath, the airway may be obstructed.

– open the child’s mouth and remove any visible obstruction

– ensure that there is adequate head tilt and chin lift, but also that the neck is not over

extended

– if the head-tilt, chin-lift method has not opened the airway, try the jaw thrust method

– make up to 5 attempts to achieve effective rescue breaths. If still unsuccessful, move on to

chest compression

Check for signs of a circulation (signs of life).

– take no more than 10 seconds to check for signs of circulation such as movement, coughing,

or normal breathing (but not agonal gasps)


Paediatrics and geriatrics

Station 66 Infant and child Basic Life Support 183

– check the pulse but take no longer than 10 seconds to do this. In a child check the carotid

pulse, in an infant check the brachial pulse

If you are confident that you have detected signs of circulation:

– continue rescue breathing, if necessary, until the child starts breathing effectively on his own

– turn the child into the recovery position if he remains unconscious

– reassess the child frequently

If there are no signs of life, unless you are CERTAIN that you can feel a definite pulse of greater

than 60 beats per minute within 10 seconds, start chest compression. To deliver chest compressions to all children, compress the lower third of the sternum.

– locate the xiphisternum and compress the sternum one finger’s breadth above this

– compress the sternum by one-third of the depth of the chest or more. In infants, use the tips

of two fingers or, if there are two or more rescuers, use the encircling technique with two

thumbs. In children, use the heel of one hand or, in larger children, the heels of both hands,

as in adults

– aim for a rate of 100–120 compressions per minute

After 15 compressions, tilt the head, lift the chin, and give two effective breaths.

Continue compressions and breaths in a ratio of 15:2.

Continue resuscitation until the child shows signs of life (spontaneous respiration, pulse, movement) or further help arrives or you become exhausted.

When to go for assistance

If more than one rescuer is present, one rescuer begins resuscitation whilst another goes for

assistance.

If only one rescuer is present, he should undertake resuscitation for 1 minute before going for

assistance. It may be possible for him to carry the infant or child whilst going for assistance.

The exception to this rule is in the case of a child with a witnessed, sudden collapse when the

rescuer is alone. In this case the cause is likely to be an arrhythmia and the child may need

defibrillation. Go for assistance immediately if there is no one to go for you.

immune system to recognise the pathogen and to mount a successful defence against it. Vaccines are

very effective both at the individual and at the population level. As a result of the UK immunisation

programme, a number of potentially deadly infectious diseases have become uncommon in the UK.
