If required, use a chart to stage puberty (Fig. 15.20). Pubertal staging has a wide normal range, with abnormalities apparent only on follow-up. Delayed or precocious puberty is not uncommon.
Physical examination techniques in children and young people
CYP usually present with a symptom. Those with acute symp­toms often have physical signs such as wheeze, but examination is normal in the majority who have chronic symptoms. Routine screening examination after infancy is unhelpful, as many pae­diatric diseases only produce signs late in the illness.
Similarities in examination between children and young people and adults
The techniques used when examining CYP are the same as those in adults, with some exceptions. Examining CYP requires a range of skills that take time to learn. The key skills involve being:
Observant during discussion or play, to identify elements of
the examination that are naturally displayed and so can be partitioned from the formal examination process, reducing the duration of what is often a stressful encounter, particularly for younger children.
Opportunistic, to examine systems as CYP present them.
Chest and cardiac auscultation may be better earlier in the examination in younger children before they become restless or upset.
Adaptive to CYPs mood and playfulness. A skilled practi-
tioner can glean most examination ndings from even the most uncooperative CYP. Usually the history suggests the diagnosis; the examination conrms it.

and young people and adults
The appropriate approach varies with CYPs age.
1 to 3 years
All children at this age can be reluctant to be approached by strangers and particularly dislike being examined. Early on, let children gradually become used to your presence and see that your encounter with their parents is friendly. Carefully observe the childs general condition, colour, respiratory rate and effort, and state of hydration while taking the history: that is, when the child is not focused on your close attention. For the formal examina­tion, ask the parent to sit the child on the parents knees. Examine the cardiorespiratory system and the abdomen with the young child sitting upright on the parents knee. With patience, abdominal examination can be done with the child lying supine on the bed next to a parent or on the parents lap. Taking your stethoscope from around your neck to use it can upset the child, so make slow, non-threatening moves. If the child starts crying,

chest auscultation and abdominal palpation become very dif­cult; take a pause. Ear, nose and throat examination often causes upset and is best left till last; suggesting that ear exam­ination will tickle can help with older children.
3 to 5 years
Some children in this age range have the condence and maturity to comply with many aspects of adult examination. They may cooperate by holding up their T-shirts for chest examination and turning round; if so, comment warmly on this cooperation and provide positive feedback on helpful behaviour. Childrens social skills regress when they are unwell, and some are very apprehensive of strangers.
5þ years
The CYP may comply with a full adult-style examination. Although children under 11 years are often not able to express themselves well, those over 5 years are able to understand and comply with requests such as nger-to-nose pointing, heel-to­toe walking and being asked to sit forwardsand take a deep breath in and hold it. Young people may nd examination particularly embarrassing. Be aware and sensitive to this, and request permissions before proceeding.
The acutely unwell children and young
people
There are many nonspecic signs that are common to a range of conditions, from a simple cold to meningitis. These include a runny nose, fever, lethargy, vomiting, blanching rash and irrita­bility. However, some signs are serious, requiring immediate investigation and management (Box 15.10).
CYP become ill quickly. If they have been unwell for less than 24 hours and initial examination reveals only nonspecic signs, they should ideally be reassessed in 1 to 2 hours if there is a high level of parental or clinical anxiety that the signs are out of keeping with a simple viral illness at that age.

Examination sequence
Ask the parent to:
Sit the child on the parent’s knees, both facing you.
Give an older child the opportunity to open the mouth
spontaneously (Roar like a lion!). If this is not successful, proceed as described here.
Place one arm over the child’s upper arms and chest (to
stop the child pushing you away, Fig. 15.22).
Hold the child’s forehead with their other hand (to stop the
child pulling their chin down to their chest).
Hold the torch in your non-dominant hand to illuminate the
childs throat.
Slide a tongue depressor inside the child’s cheek with your
dominant hand. The child should open their clenched teeth (perhaps with a shout), showing their tonsils and pharynx.
Abnormal ndings
Healthy tonsils and pharynx look pink; when inamed, they are
crimson–red.
Inspecting the throat (see Fig 15.22) reveals the presence, but
not the cause, of the infection; pus on the tonsils and pharynx does not differentiate a bacterial from a viral infection (p. 210).

symptoms such as weight loss, fevers or night sweats, these are typically a normal, healthy immune response to infection. Only rarely are they due to malignancy (Box 15.12).
Cardiovascular examination
Fig. 15.22 How to hold a child to examine the mouth and throat.
Fig. 15.23 How to hold a child to examine the ear.
To assess the pulse (rate and volume), the brachial pulse in the antecubital fossa is best used for children below 2 t o 3 years and the radial pulse in older CYP. Measure blood pressure using a cuff sized two-th irds the dista nce from elbow to shoulder tip. Repeat with a larger cuff if the reading is elevated. If in doubt, use a larger cuff, as smaller cuffs yield falsely high values.
Respiratory examination
Abnormal ndings
The child under 3 years has a soft chest wall and relatively small, stiff lungs. When the lungs are made stiffer (by infection or uid), the diaphragm must contract vigorously to draw air into the lungs. This produces recession (ribs sucking indtracheal, intercostal and subcostal) and paradoxical outward movement of the abdomen (wrongly called abdominal breathing). These important signs of increased work of breathing are often noticed by parents. Older children may be able to articulate the accompanying symptom of dyspnoea.
In young children, their small, thin chests transmit noises readily, and the smaller airways are more prone to turbulence and added sounds. Auscultation may reveal a variety of sounds, including expiratory polyphonic wheeze (occasionally inspiratory too), ne end-expiratory crackles, coarse louder crackles trans­mitted from the larger airways and other sounds described as pops and squeaks (typically in the chest of recovering patients with asthma).

splenic enlargement extends towards the left iliac fossa. In older children the enlarged spleen edge moves towards the right iliac fossa. Faecal loading of the left iliac fossa is common in con­stipation. Rectal examination is rarely indicated in CYP, but ex­amination of the anus for ssures (common with constipation) can be helpful where appropriate.
Neurological examination
Test power initially by watching the CYP demonstrate their strength against gravity. Ask them to lift their arms above their head, raise their leg from the bed while they are lying down and stand from a squatting position. If appropriate, test power against your strength.
Neck stiffness in CYP is usually apparent when you are talking to them or their parents. CYP with meningitis will not want to move, and if they are forced to do so, the neck remains aligned with the trunk. With a young child, move a toy to catch their attention and see if they move their head.
Spotting the sick children and young people
It can be difcult to identify CYP with severe illness, particularly younger children. With experience you will learn to identify whether CYP are just miserable or really ill. Early-warning scores (e.g. Paediatric Early Warning Score (PEWS), Fig. 15.24) can help. Certain features correlate with severe illness (Box 15.13).
Child protection
CYP who experience neglect or physical and/or emotional abuse are at increased risk of health problems. At-risk CYP may already be known to other agencies but do not assume this is the case when interagency communications are not available to you.
15.14 Signs that may suggest child neglect or abuse
Behavioural signs
Frozen watchfulness
Passivity

Injuries from physical abuse can often be detected visually. Consider nonaccidental injury if the history is not consistent with the injury or if the injury is present in unusual places such as over the back. It may be difcult to detect neglect during a brief encounter, but consider it if the child appears unkempt, has unexplained pain/discomfort or is socially withdrawn. The parent–child relationship gives insight into neglect; the child is apparently scared of the parent (frozen watchfulness) or the parent appears oblivious to the childs attention (Box 15.14).
Remote consultation in paediatric practice
15.13 Clinical signs associated with severe illness in children
Fever >38C
Drowsiness
Cold hands and feet
Petechial rash
Neck stiffness
Shortness of breath at rest
Tachycardia
Hypotension (a late sign in shocked children where blood pressure is
initially maintained by tachycardia and increased peripheral vascular resistance)
The recent global pandemic has made necessary remote consultation. While this may become part of normal practice in future, it has signicant limitations as well as advantages (see
Chapter 21). There is a risk that remote consultation can adversely
affect the appropriate assessment of CYP in communities or households where technology and access to WiFi do not enable a visual review of the child. Where video consultation is possible, always ensure that CYP are present at least at the start of the consultation so that you can ask specific questions of them and observe any specic signs that may help your clinical decision making. Younger CYP, in particular, get bored very easily during video consultation and tend to disappear off camera.

Ismail, 4 months old, is brought in to see you by his mother. She is anxious as he has had diarrhoea for several days. He is breastfed.
Please perform a newborn examination, focusing on the cardiovascular system
Introduce yourself to the mother. Wash your hands thoroughly and wear personal protective equipment (PPE) as per local guidance.
Carry out a general inspection:
Look at the general state of the infant. Are they alert and interested, or quiet and lethargic?
Examine for signs of dehydration:
Sunken eyes, sunken fontanelle, reduced skin turgor, dry mucous membranes Measure capillary rell by pressing on the midsternum for 5 seconds and counting the time for rell Count the respiratory rate over 1 minute to identify tachypnoea Count the pulse rate and pulse volume in the brachial artery. Measure the childs blood pressure. Assess the childs neurological status (AVPUdalert, verbal, pain, unresponsive).
Is there any associated infection/condition that might be causing them to have diarrhoea. Perform an examination of the systems to exclude additional
diagnoses, i.e.
respiratory crackles of pneumonia
inamed ear for otitis media
bulging fontanelle of meningitis
Dispose of any PPE you have used, wash your hands and thank the parent and child.
Suggest a diagnosis
Diarrhoea is common and, with it, dehydration. Most children can recover if an adequate assessment of dehydration is made and they are provided with rehydration. Learn how to assess degrees of dehydration (commonly classied as 5, 10 or 15% dehydration) and how to calculate volume of uid to replace (body weight in kg  percent dehydration  10 ¼ volume in mL to be replaced). Fluid replacement is in addition to routine daily requirements. If there are continued diarrhoeal losses, uids may need recalculated every 4 to 8 hours to take account of this.
Suggest investigations
Heart rate, respiratory rate, blood pressure, pulse oximetry.

OSCE example 2: Chronic cough
Joanne, 2 years old, who has had a problem with cough. The cough has been present for the past 8 weeks following a severe viral infection. The cough affects her sleep but not her appetite, weight or activities.
Please perform a chest examination, focusing on the respiratory system
Introduce yourself to the parent and child. Wash your hands thoroughly, and wear PPE as per local guidance. Ensure that you use a stethoscope that has
been appropriately cleaned.
Carry out a general inspection: are there any signs of acute or chronic respiratory distress?
Look for chest wall deformity (pectus excavatum, Harrison ’s sulcus).
Look for signs of respiratory distress (tachypnoea, indrawing, accessory muscle use).
Count the respiratory rate over 1 minute.
Look at the colour and perfusion of the patient (cyanosis, pallor, sweatiness).
Look for nger clubbing and poor weight gain.
The respiratory rate is 20 per minute (normal), and there are no other abnormal ndings on inspection except that you can hear the child have an
intermittent moist cough.
Auscultate: warm the stethoscope.
Auscultate the respiratory system in all lung regions, anteriorly and posteriorly, with the chest fully exposed.
Low-pitch rhonchi are auscultated in all lung regions. No crepitations are heard. Air entry is normal.
Heart sounds are normal with no murmur.
Palpate: consider palpation if there are chest-wall abnormalities or differential chest expansion on inspection, to look for differential chest-wall movement.
Dispose of any PPE you have used, wash your hands and thank the parent and child.
Summarise your ndings
This child has moist cough with low-pitch rhonchi on auscultation but a normal respiratory rate and no respiratory distress.

OSCE example 2: Chronic coughdcont'd
Suggest a diagnosis
Postviral cough is common in young children. Cough usually resolves within 6 weeks. A prolonged cough, particularly if moist requires clinical review. Persistent bacterial bronchitis often self resolves in many children, but for some the recovery can be aided by a course of broad-spectrum antibiotics (i.e. amoxicillin). If the moist cough resolves but recurs on stopping antibiotics or fails to stop with antibiotics, then further investigation may be required.
Suggest initial investigations
Chest x-ray if recurrence or non-improvement.
Integrated examination sequence for the newborn child
Perform a general examination:
Looks well and is well grown? Dysmorphic features? Posture and behaviour? Does the cry sound normal?
Skin: note cuts, bruising, naevi (haemangiomas or melanocytic), blisters or bullae.
Head: check shape, swellings, anterior fontanelle, cranial sutures.
Eyes: check for jaundice, ocular movements and vestibular function; perform ophthalmoscopy.
Nose: check patency.
Mouth: check mucosa, tongue, palate, jaw and any teeth.
Ears: note size, shape and position; check the external auditory meatus.
Neck: inspect and palpate for asymmetry, sinuses and swellings.
Examine the cardiovascular system:
Inspect: pallor, cyanosis and sweating.
Palpate: apex, check for heave or thrill, count heart rate, femoral pulses, feel for hepatomegaly.
Auscultate: heart sounds I and II, any additional heart sounds or murmurs.
Examine the respiratory system:
Inspect: chest shape, symmetry of movement, respiratory rate, respiratory distress: tachypnoea, suprasternal, intercostal and subcostal recession,
aring of nostrils.
Auscultate anteriorly, laterally and posteriorly, comparing sides.
Examine the abdomen:
Inspect: abdomen, umbilicus, anus and groins, noting any swellings.
Palpate: supercial, then deeper structures. Spleen, then liver.
Examine the perineum:
Both sexes: check normal anatomy.
Male: assess the penis, noting shape; check the urethral meatus is at the tip. Do not retract the foreskin. Palpate the testes, and the inguinal canal if
the testes are not in the scrotum. Transilluminate scrotal swellings.
Examine the spine and sacrum:
With the infant in the prone position, inspect and palpate the entire spine for neural tube defects.
Examine the neurological system:
Inspect: asymmetry in posture and movement, any muscle wasting.
Pick the baby up to note any stiff or oppy tone.
Sensation: does the baby withdraw from gentle stimuli?
In dim light, the eyes should open; in bright light, babies screw up their eyes.
Check the primitive reexes:
Check grasp responses, ventral suspension/pelvic response to back stimulation, place-and-step reexes, Moro reex, root-and-suck responses.
Inspect the limbs:
Inspect: limbs, counting digits and checking feet are, or can be, normally positioned.
Check hips for developmental dysplasia/dislocation.
Weigh and measure:
Weigh the infant to the nearest 5 g.
Measure: occipitofrontal circumference, crown–heel length (neonatal stadiometer).
Record on a centile chart.

368 PATIENTS WITH MENTAL ILLNESS AND LEARNING DISABILITY
https://t.me/med1917
Mental disorders are very common, frequently coexist with physical disorders and cause much mortality and morbidity. Psychiatric assessment is, therefore, a required skill for all clini­cians. It consists of four elements: history, mental state exami­nation (MSE), selective physical examination and collateral information. Each element can be expanded considerably, so the assessment must be adapted to its purpose. Is it a quick screening of a patient presenting with other problems, a conr­mation of a suspected diagnosis or a comprehensive review for a second opinion?
The history
General approach
The distinction between symptoms and signs is less clear in psychiatry than in the rest of medicine. The psychiatric interview, which covers both, has several purposes: to obtain a history of symptoms, to assess the present mental state for signs and to establish rapport that will facilitate further management.
A comprehensive history covers a range of areas (Box 16.1), but the nature of the presenting problem and/or the referral question, and the setting in which the history is being taken, will determine the degree of detail needed for each. When seeing someone in the Emergency Department with a rst episode of psychosis, the focus is on symptoms, recent changes in func­tion, family history and drug use; when interviewing someone in an outpatient clinic with a possible personality disorder, assessment concentrates instead on their personal history, which is essentially a systematised biography (Box 16.2).

Sensitive topics
Some subjects require a particular skill. The common theme is reluctance to disclose, which can arise because the information is private and disclosure is potentially embarrassing (such as sexual dysfunction), distressing (major previous traumatic experiences, such as rape, childhood sexual abuse, witnessing a death) or incriminating (illicit drug misuse, other crimes, homicidal ideas). For interviews undertaken in non-clinical settings, such as police sta­tions or prisons, or for the provision of court reports, potentially incriminating disclosures are obviously especially pertinent, and it is important to be clear with the patient about any limits to condentiality in your interview. Some disclosures, such as those relating to sexual orientation or gender identity, may expose pa­tients to the real or perceived risk of hostility or discrimination.
Try to develop rapport early in the interview, if possible, and to consolidate it before raising a sensitive topic, although some­times you must cover such material without delay. It is particularly important to ask about suicidal thoughts.
While clinicians should be able to interview patients regardless of their age, gender, ethnic origin or sexual orientation, the skills required may vary because patient attitudes may differ. For example, it may be more difcult for a male patient to discuss erectile dysfunction with a female than a male interviewer, or for an adolescent patient to relate to an interviewer in their late middle age than someone closer to their own years. Clinicians need to be aware of the potential effects of demographic and other differences between themselves and their patients.
The uncooperative patient
Adapt your approach to a patient who is mute, agitated, hostile or otherwise uncooperative during the interview by relying more on observation and collateral information. The safety of the pa­tient, other patients, staff and the wider public is paramount, so your initial assessment of an agitated or hostile patient may be only partial.
The mental state examination
The MSE is a systematic evaluation of the patients mental condition at the time of interview. The aim is to establish signs of mental disorder that, taken along with the history, enable you to make, suggest or exclude a diagnosis. While making your spe­cic enquiries, you need to observe, evaluate and draw in­ferences in the light of the history. This may be daunting, but with good teaching, practice and experience, you will learn the skills.
The MSE incorporates elements of the history, observation of the patient, specic questions exploring various mental phe­nomena, and short tests of cognitive function. Like the history, its focus is determined by the potential diagnoses. For example, detailed cognitive assessment in an elderly patient presenting with confusion is crucial; similarly, you should carefully evaluate mood and suicidal thoughts when the presenting problem is depression.
