    Breast examination 

    Written in April 2011 by Andrew Boyle and Alistair Tindell.

    How to describe a lump

    •  Site (e.g. “mass in the upper inner quadrant of the left breast”).

    •  Overlying Skin (Colour? Punctum? Discharge?)

    •  Size.

    •  Shape.

    •  Consistency.

    •  Surface (craggy/smooth).

    •  Temperature.

    •  Tenderness.

    •  Fluctuance.

    • 

    Tethering to skin.•  Transillumination.

    Always check local lymph nodes if lump is found.

    Malignant Lump

    •  Overlying skin changes – tethering, peau d!orange.

    •  Nipple inversion/discharge.

    •  Non-tender, firm.

    •  Non-fluctuant, no transillumination.

    •  Irregular, craggy.•  Attached to deep tissues ± skin.

    Triple Assessment 

    (very likely to be asked this, good to know for OSCE and clinical attachments):

    •  Under 35y:

    1.  History and examination.

    2.  Ultrasound (+ mammography if >35yrs).

    3.  Fine needle aspiration (faster, only shows cells) or core biopsy (shows structure).

    For distant disease, further investigations are needed to detect metastases (e.g. LFTs, CT, skeletal survey).

    Staging 

    Nottingham Prognostic Index (tumour size, tumour grade, lymph node status).

    Sentinel node biopsy Identifies draining lymph node during surgery. Injection of blue dye into tissue shows which lymph node drains the

    area first by this lymph node turning blue first. This lymph node is then removed for pathological assessment for

    cancerous cells during the surgery. If positive, axillary node clearance will be performed. If negative, no further

    removal of lymph nodes is required.

    Treatment 

    MDT, including breast care nurses, radiologists, oncologists, pathologists…

    Combination of:

    •  Surgery, including lymph nodes and reconstruction.

    •  Chemotherapy.

    •  Endocrine agents e.g. Tamoxifen, Herceptin. Pathology instructs which to use.

    •  Radiotherapy.

    • 

    And for distant disease, palliation.

    Cranial nerves III-VII examination (page 1 of 3)

    Written in April 2011 by Sam Brookfield and Liying Low.

    Inspection 

    Inspection of the face can include looking for facial weakness, asymmetry and any involuntary movements.

    Inspection of the eyes includes looking at the pupils, eyelids for ptosis and eyes for nystagmus.  

    Pupillary Responses

    Pupil responses are afferent via CN II and efferent via CN III and are often considered part of CN II examination but

    included here for completeness. Direct (same eye) and indirect (opposite eye) pupillary responses to light should be

    assessed. When focusing from a distant to a close object pupils should converge and constrict.

    Eye Movements 

    Start by asking the patient to look at your finger, asking if they have any double vision (diplopia) and looking for

    nystagmus. If they do have diplopia, ask whether it is vertical or horizontal. Then trace out an H pattern, looking for

    nystagmus or ophthalmoplegia and asking the patient to report any double vision. In identifying the lesion it helps to

    remember which nerves supply which extra-ocular muscle.

    Trigeminal Nerve (CN V) 

    The trigeminal nerve is sensory to the face, which can be assessed by light touch –cotton wool or a fingertip. Start by touching the patient on the sternum as a reference

    point, then testing each side of the face and asking, “Can you feel this? Does it feel the

    same?” to the three areas of the trigeminal nerve as shown on the diagram. The

    trigeminal nerve also supplies touch (not taste) to the anterior tongue, although, this is

    not often tested.

    It is also motor to the muscles of mastication. Ask the patient to clench their teeth and

    palpate masseter and temporalis bulk. Ask the patient to open their jaw against

    resistance, and move from side to side.

    Jaw Jerk

    Not routinely tested. Place one finger in the centre of the jaw and gently strike your

    finger with a tendon hammer. It is normally absent or a slight, brisk contraction of the

    masseter may suggest an upper motor neurone lesion. The jaw jerk is both afferent and

    efferent via the trigeminal nerve.

    Corneal Reflex

    Not routinely tested. Use a wisp of cotton wool to stimulate the lower outer quadrant of the cornea. This should cause

    direct and consensual blinking. The corneal reflex is afferent via CN V and efferent via CN VII.

    Facial Movements

    Ask the patient to raise eyebrows/wrinkle forehead, and show their teeth. Test power by resisting screwing up eyelids

    and puffing out cheeks. You can also test taste to the anterior tongue, lacrimation and hearing.

    Fundoscopy

    Written in April 2011 by Andrew Lumsden and Sarah Syeda.

    Tips on using the direct ophthalmoscope

    •  Use the same eye as the patient!s eye you!re examining and use the same hand, e.g. when examining the

    patient!s right eye, use your right eye and hold the ophthalmoscope in your right hand.

    •  Use the other hand to stabilise your head and lift the patient !s lid if needed.•  Adjust the power of the lens to minus (myopic) direction until the fundus is in view.

    Red reflex should appear red. Any opacities (they look like shadows) indicate e.g. cataracts.

    Optic disc

    Common scenarios likely to appear

    1. Diabetic retinopathy

    •  Non-proliferative

    o  Dot + blot haemorrhages.

    o  Hard exudates.

    o  Microaneurysms.

    Cotton wool spots (pre-proliferative).

    •  Proliferative – includes the above +…

    New vessels, classified as:

    a.  NV at disc.

    b.  NV elsewhere.•  Photocoagulation scars may be visible in the periphery (they look like black/white burns).

    2. Hypertensive retinopathy – signs include:

    •  A-V nipping: arteries nip the veins where they cross. You may see the vein bulge adjacent to site of nipping.

    •  Flame haemorrhages.

    •  Cotton wool spots.

    •  Exudates.

    • 

    Optic disc swelling.•  Microaneurysms.

    3. Papilloedema

    •  Optic disc swelling (disc margins indistinct). Most commonly due to ICP. May also be due to papillitis due tooptic neuritis.

    4. Optic atrophy

    •  Pale optic disc. May be due to optic neuritis, glaucoma, ischaemic/toxic optic neuropathy.

    Intramuscular injection

    Written in April 2011 by Philip Chan and Kyaw Zayar Thant.

    Intramuscular injections

    IM injections are given into well-perfused muscles. The rate of absorption is faster than subcutaneous injection butslower than intravenous administration. Indications for IM injection include delivering vaccines.

    Five “rights” – right patient, right drug, right dose, right route, right time.

    Five sites 

    •  Mid-deltoid

    •  Maximum volume 1ml.

    •  Administer 2.5cm below acromion process.

     

    Avoid brachial artery and radial nerve.•  Ventrogluteal

    •  Maximum volume 2.5ml.

    •  Administer at hip.

    •  Dorsogluteal

    •  Maximum volume 4ml.

    •  Administer in the upper outer aspect of gluteal muscle.

    •  Avoid sciatic nerve and superior gluteal arteries.

    •  Vastus lateralis

    •  Maximum volume 5ml.

    •  Administer in outer middle third of thigh.

    •  No significant structures to avoid.

    •  Rectus femoris•  Used for self-administration and infants due to ease of access.

    The site used is influenced by age, patient health, muscle bulk and type of medication being injected. Care must be

    taken to avoid neurovascular structures.

    Size of needle

    The size (gauge and length) of needle used depends on the injection site, muscle mass, amount of subcutaneous fat

    at the site and the weight of the patient. Needles commonly used are 21-23G and 2.5-5.0cm in length. Always consult

    hospital local guidelines.

    Z-track technique

    The skin over the injection site is pulled to the side before the needle is introduced. When the needle is withdrawn,

    the skin is released immediately afterwards. This technique ensures that the medication is trapped in the region that it

    is required, reducing leakage. The online resource produced by the University of Nottingham gives a good visualexplanation of this (see link below). The Z-track technique is considered best practice.

    After the procedure, do not massage the injection site as this causes leakage and local irritation. However, light

    exercise or stretching of the muscle may help increase absorption of the medication.

    Intravenous cannulation

    Written in April 2011 by Dilane Peiris and Lucy Lynch.

    Introduction

    Cannulation or intravenous (IV) access is the !bread and butter" of junior doctors" clinical skills. Indications for apatient to have IV access, includes:

    •  Requirement for IV fluids or medication.

    •  Surgical or endoscopic procedures.

    •  Radiological investigations requiring contrast media.•  Cardiac arrest or peri-arrest situations.

    However, patients are often left with cannulas in-situ for days, placing them at risk of local infection, thrombophlebitisand sepsis. It is thus essential to have the skill to place a cannula, and review them frequently.

    Equipment

    Prepare a small tray with:

    •  Gloves.

    •  Cannula (appropriate size depending on indication).

    •  Adhesive cannula dressing.

    •  Alcohol skin wipe or chlorhexidine spray.

    •  Gauze.

    •  5 mL syringe.

    •  5 mL normal saline (check expiry date).•  Sharps bin.

    Procedure

    •  Apply tourniquet, preferably to the non-dominant arm.

    • 

    Select a suitable vein through palpation and sight. Ensure that it is reasonably straight and not too tortuous.•  Put on gloves and sterilise the area with an alcohol swab. Following this, avoid touching that area again.

    This is a sterile procedure.

    •  Allow chlorhexidine/alcohol to dry.

    •  Unsheathe the cannula.

    •  Hold the cannula between your thumb, index and middle fingers, making sure not to touch the shaft of the

    cannula.

    •  Approach the vein at 10-40° in the direction of blood flow (i.e. up the arm). Your thumb should be providing

    the force and, as such, should be positioned at the back of the cannula, over its rear port. Your index finger

    and middle finger should fall either side of the cannula shaft and hook lightly round the wings. This providesthe !steering".

    •  Using your other hand, retract the skin over the vein, and anchor it in place.

    •  Warn the patient just prior to insertion.

    •  Pass the cannula through the skin and into the vein. A !flashback" of blood in the body of the cannula should

    be seen if the cannula is in the vein. You will also feel a!give

    " as you pass through the wall of the vein into

    the lumen.

    •  Ease the plastic tubing of the cannula off the introducer and into the vein.

    •  Release the tourniquet.

    •  Remove the introducer entirely, and clamp the vein just proximal to the cannula tip to prevent blood leaking

    out.

    •  Place the introducer in a sharps bin.

    •  Apply the plastic screw cap to the rear port.

    •  Secure the cannula with a suitable adhesive. Write the date of insertion on the dressing.

    •  Draw up 5 mL of normal saline and flush the cannula through the top port. If it fails to flush or causes pain, itis in the wrong place and should be removed and re-sited.

    After the procedure

    • 

    Clean up and dispose items in the appropriate receptacles (sharps bins and clinical waste bins).•  Ensure that the patient is comfortable.•  Thank the patient, wash your hands and document the insertion.

    Otoscopy and free-field voice test

    Written in April 2011 by Andrew Kidd and Innes Hynd.

    Anatomy of the ear

    The pinna (or auricle) is the outer projecting portion of the ear. It is composed of elastic cartilage covered with skin.The external ear canal is about 2-5cm long in adults and extends from the external auditory meatus to the tympanicmembrane.

    The tympanic membrane consists of the pars tensa and the pars flaccida. The malleus handle lies in the middle layerof the pars tensa. The most medial structure in the drum is the lateral process of the malleus. The tip of the handle iscalled the umbo, and a cone of light can usually be seen extending anteroinferiorly from the umbo.

    Otoscopy equipment and technique

    The otoscope consists of a handle and a head. The head contains a light and magnifying lens. The front end of theotoscope has an attachment for disposable plastic ear specula. The speculum size should be appropriate for thepatient's canals. Hold the otoscope in a pencil grip with the hand of the same side as the ear you are about toexamine. The pencil grip allows the side of your hand to rest on the side of the patient's face, reducing the risk oftrauma if the patient’s head suddenly moves.

    Free-field voice testing

    This is a useful test of hearing where each of the patient’s ears are tested in turn. The examiner should stand to theside of the patient and reach their hand behind the patient’s head to rub the ear that is not being examined. This waythe noise created prevents the patient hearing through this ear.

    The examiner should begin at arms length by whispering a combination of 3 numbers (e.g. 5, 8, 1) that the patientshould repeat. If the patient does not hear this then move to 6 inches beside the patient’s ear and use anotherrandom whispered combination. If the patient’s responses have not yet been accurate, then the process is repeated,again starting at arms length but this time with a conversational normal voice, not whisper. If this is still not heard thenuse a conversational normal voice at 6 inches.

    N.B. The whisper should be a “loud” whisper.

    Please note that the Rinne and Weber tuning fork tests may be relevant in a cranial nerve examination, but they donot test quality of hearing in patients and are not discussed here or recommended in an ENT examination. Pure toneaudiometry is the most accurate way of formally assessing a patient’s hearing.

    Peripheral arterial examination

    Written April 2011 by Claire Adams and Kerri Devine.

    General inspection 

    It is good practice in any examination to take a step back and make some general observations about the patient.

    Abdominal Aortic Aneurysm

    This is detected as a pulsatile and  expansile mass found above the level of the umbilicus (the aorta bifurcates here).

    To demonstrate this, place one hand on either side of the pulsation – if it is expansile, your hands will be seen to

    move apart in time with the pulse. A mass that is pulsatile but not  expansile may only be transmitting a pulse

    underneath it, and it is normal to palpate a pulse in thin subjects.

    Anatomical Landmarks for Lower Limb Pulses 

    1.  Dorsalis pedis – lateral to extensor hallucis longus tendon on dorsum of foot. It is a common mistake to aim

    too low on the foot, and be sure to palpate gently or you may occlude a weak pulse.  

    2. 

    Posterior tibial – in the groove between the Achilles ! tendon and medial malleolus. 

    3.  Popliteal – in popliteal fossa. Palpate bimanually with patient!s leg relaxed and slightly flexed at knee.

    Difficult to feel! Consider a popliteal aneurysm if easily felt. Remember that if you have already managed to

    feel the lower pulses, it should be in there! 

    4.  Femoral – the femoral pulse is located at the “mid-inguinal point” – halfway between the anterior superioriliac spine and the pubic symphysis. It is good exam practice to demonstrate locating these landmarks inorder to pinpoint the femoral pulse. 

    Ulcers

    Remember to look between the patient!s toes for ulceration and necrosis, and lift their heels off the bed to perform athorough inspection.

    A venous  ulcer is typically in the “gaiter area” over the medial malleolus. There may also be other signs of highvenous pressure (usually due to varicose veins or previous DVT). These include haemosiderin deposition (a reddish

    brown stain to the legs), oedema, lipodermatosclerosis, and varicose veins.

    An arterial  ulcer has typically a "punched out! appearance with some areas of necrosis and is more likely to be

    painful.

    A neuropathic  ulcer is a painless ulcer occurring on pressure areas, e.g. the heel – they are often surrounded by

    callous. Diabetic patients can present with neuropathic ulcers, although in practice may be a mixed aetiology (arterial

    and neuropathic).

    Buerger!s Test

    With patient lying supine, elevate both legs at the same time to approximately 45°. Observe for onset of pallor in the

    soles of the feet. The smaller the angle raised at which this occurs, the more severe the ischaemia (the angle at

    which pallor occurs is termed “Buerger!s angle”). Then swing the patient!s legs round so they are hanging off the side

    of the bed and observe for reactive hyperaemia (the foot turns purplish). “Pallor on elevation” followed by “rubor on

    dependency” is a positive Buerger!s test.

    Suturing

    Written in April 2011 by Devvrat T. Katechia and Omer Alanie

    Suturing

    The very first thing to mention about this station is that only 2 marks out of the 20 are actually awarded for thesuturing technique, so it is important not to get too disheartened if in the exam your suture is not exactly symmetrical.

    The objective of suturing the skin is to approximate, oppose and evert the wound edges, thereby reducing the risk of

    infection, promoting wound healing and providing a better cosmetic outcome.

    Communicate with the patient very clearly what you are going to do and the fact that it should not be too painful.

    It is important to maintain a sterile environment when suturing a wound and for the purposes of the exam I would

    advise stating this out aloud.

    Before suturing the wound it is best to prepare the trolley with the equipment that you require, namely: sterile gloves,tooth forceps, sutures, needle holder, suture scissors, antiseptic for cleaning the wound, local anaesthetic and a

    syringe. In the exam this may all be laid out for you.

    With regard to the local anaesthetic, it is always best to check the details of the anaesthetic prior to injecting. State

    the name of what you!re injecting and the expiry date of it to the examiner. Allow sufficient time for the anaesthetic to

    act and in the exam once you state this, the examiner may just ask you to proceed.

    Suturing technique

    Do not pull the suture too hard as this will place tension on the suture and this will impair wound healing due to tissuestrangulation and wound oedema. Leave sufficient thread when cutting the suture to allow easier removal at a laterdate

    Finally it is essential to dispose of the sharps accordingly.

    Document the site of the wound closure, date, suture material used and the type of knot used in the medical notes.

    Needle point

    Suture thread

    Needle body

    Mounting the needle: Insert your thumb and ring finger inside the needle holder. Pickup the suture 1/3 along the needle body from the suture thread attachment (known as

    swage). If you hold the suture needle at the tip then this will damage the needle and

    therefore it will not pierce the skin as effectively. If you need to manoeuvre the needle,

    use the forceps and not your fingers!

    Suture placement: Hold the skin edge using forceps and insert the needleapproximately 5mm from the wound edge. Penetrate the skin with the needle at a 90°

    angle. This will ensure symmetrical wound closure. Pull the needle through usingforceps and allow sufficient suture material to tie a knot.

    Knot tying: Use the needle holder to hold the short piece of thread. The short end of

    the suture is then grasped with the tip of the needle holder and pulled through the loopsof the long end by crossing the hands, such that the 2 ends of the suture material are

    situated on opposite sides of the suture line. Repeat the process by rotating the long

    end once and pulling through, then pulling the short end and again crossing your armsThis is a simple interrupted suture.

    Visual acuity testing

    Written in April 2011 by Andrew Lumsden and Sarah Syeda.

    One of the main functions of the optic nerve is vision. There are three elements: acuity, fields and colour vision.Here, we will focus on testing visual acuity. The method of assessing this is the Snellen chart and near vision chart.

    A. Snellen chart

    Snellen charts are used to test a patient!s distance vision.

    Preparation

    The patient should sit 6 metres away from the Snellen chart, however, often they will sit at 3 metres and look at a 3

    metre chart through a mirror. The patient should be asked to wear spectacles or contact lenses for the test, if they

    require them.

    Assessing and recording vision

    Each eye is tested individually by covering one eye at a time and getting the patient to read from the largest letter to

    the smallest line they can read. This is repeated for the other eye, and the results are recorded as follows:

    Distance from chart / Smallest line read (e.g. Left eye 6/18, Right eye 6/9.)

    The number system on the Snellen chart (60, 36, 24, 18, 12, 9, 6, etc.) refers to the distance at which someone with

    normal vision could read the line.

    If a patient gets some of the letters on a line correct, this should be recorded as:

    Distance from chart / Smallest line read with some mistakes MINUS the number of incorrect letters

    or Distance from chart / Smallest line with all letters correct PLUS the number of correct letters on thesmaller line.

    For example, a patient correctly identifies four letters out of five on the 12 line could be recorded as:

    6/12 – 1 or 6/18 + 4. 

    A pinhole should be used and each eye reassessed. If visual acuity improves, this suggests there is a refractive error.

    If a patient is unable to read any of the letters, they should be moved closer to the chart (1 metre at a time until theyare 1 metre away from chart). If they are still unable to read any of the letters, the following should be attempted:

    •  Counting fingers – hold fingers up at less than one metre.

    •  Hand movements – wave hand in front of patient (wave up and down and also side-to-side).

    • 

    Light perception – shine a light in the eye. If not seen, recorded as “no light perception”.

    Normal vision is 6/6. Partially sighted is between 6/60 and 3/60. Blindness is below 3/60.

    B. Near vision chart

    Preparation

    The patient should be asked to hold the test sheet at the distance they would normally hold a book (this should be

    around 40cm). The patient should be allowed to wear spectacles or contact lenses for the test.

    Assessing and recording vision

    The patient should be asked to read the sentences and the results should be recorded as the smallest line that canbe read (according to the scale on the chart).

    Digital rectal examination

    Written in April 2011 by Devvrat T. Katechia

    Digital rectal examination

    Prior to performing a digital rectal examination it is essential to communicate very clearly with the patient the

    procedure and what it entails.

    You must request a chaperone when performing this examination.

    For the purpose of the examination it is best to communicate and present what you are doing with the examiner as

    you proceed. This prevents you from forgetting examination steps or findings.

    Position

    The patient should be positioned on the left hand side with his buttocks close to the edge of the examining table. Ask

    the patient to draw their knees up to their chest.

    Inspection

    Comment on the presence of any lumps, ulcers, inflammation, rashes, excoriations and skin tags.

    As the patient strains down, observe for the presence of any haemorrhoids.

    Palpation

    It is always best to warn the patient before you insert a finger up their anus.

    As you insert your index finger, look at the patient for any signs of tenderness or pain. If the patient complains of

    severe pain this may indicate the presence of an anal fissure.

    Presenting examination findings

    It is always best to rehearse presenting your findings either with friends or in front of the mirror. This helps you look

    as slick as possible and enables you to obtain the mark for excellence.

    For the rectal examination you may say the following:

    On examination of Mr. X!s perianal region and rectum, there were no abnormalities to note on inspection. On

    palpation there was normal anal tone and no irregularities to note in the rectum. The prostate was of normal size,

    consistency and surface. On examining the glove there is no mucus, faeces or blood. I would like to complete the

    examination by performing a full abdominal examination on this patient.

    History: Assessing suicide risk

    Written in April 2011 by Philip Chan.

    Risk factors for suicide risk

    •  Male gender.

    •  Age.

    •  Previous suicide attempt or self-harm.

    •  Psychiatric illness.

    •  Hopelessness.

    •  Social isolation.

    •  Low socio-economic status.

    •  Unemployment.

    •  Alcoholism and drug abuse.•  Major life events, e.g. difficult childhood.

    Actor behaviour when assessing suicide risk

    •  Do not be put off if the actor does not respond to your questions. Allow enough silence for them to

    reflect, but don!t forget that you have a long list of questions to get through in five minutes, so just keepasking. The examiner will give you the marks even if they don !t answer.

    •  The actor will often not make eye contact with you throughout the entire interview.

    •  A lot of marks will be allocated for actor !s assessment, and so it is important that you use good

    communication skills, e.g. showing empathy, using appropriate body language, leaning in to speak to thepatient, allowing silences, speaking at the appropriate volume.

    Assessing a real patient

    •  It is unrealistic to expect you to take a full psychiatric history and perform a full mental state examination in a

    five-minute OSCE station. However, this is what would be expected in a real life scenario.

    •  Full psychiatric history taking and the mental state examination will be taught in more detail during your

    psychiatry block in your clinical years.

    •  Drug overdose is one of the most common A&E presentations and so suicide risk assessment is animportant skill that you must learn.

    History: Chest pain

    Written in April 2011 by Kyaw Zayar Thant.

    Main differential diagnoses and typical presentations

    When considering the cause of chest pain, visualise the anatomy of the chest. Pain may arise from the

    cardiovascular system (heart & aorta), respiratory system (lungs, pulmonary vessels), GI system (oesophagus, upperstomach) or musculoskeletal system (chest muscles, rib cage).

    Cardiovascular

    1.  Acute coronary syndrome (STEMI, NSTEMI, unstable angina)

    Middle aged/elderly patient with central, !crushing/tight" chest pain, radiating to either both arms ± neck/jaw.

    Pain is sudden onset while patient is at rest, not relieved by GTN, antacids or resting and lasts more than just a few mins. (cf. stable angina, which is pain on exertion, relieved by rest/GTN; lasting a few mins). May

    have associated breathlessness, nausea/vomiting, sweating and sense of !impending doom". Typically,

    there is history of angina, MI, stroke, intermittent claudication and other cardiovascular risk factors (diabetes,hypertension, hyperlipidaemia, smoking, alcohol excess, family history).

    2.  Aortic dissection

    Severe, !tearing" chest pain, located centrally or to one side, radiating to the back. May have a difference inblood pressure and radio-radial delay between the arms.

    3.  Pericarditis

    Central, sharp chest pain which may radiate to the left shoulder or neck, exacerbated by lying down,

    respiration or movement and relieved by leaning forward or use of NSAIDs. Mainly occur in patients post-MI.Respiratory

    4. 

    Pulmonary embolism

    Presentation of PE can be varied and difficult to diagnose. Typically, history of sudden onset shortness of

    breath, ± pleuritic chest pain ± haemoptysis in someone with a hot, swollen, tender calves (DVT) or other

    risk factors for blood clots (surgery, malignancy, pregnancy, period of immobility)

    5.  Pneumothorax

    Sudden onset of pleuritic chest pain with breathlessness.GI 

    6.  Oesophagitis/GORD

    Central, !burning" chest pain with no radiation, precipitated by heavy meals or bending down, e.g. to touch

    his toes, relieved by antacids. May have associated waterbrash, acid brash.7.

     

    Oesophageal spasm

    Oesophageal spasm can mimic angina closely; i.e. central crushing chest pain, which may radiate to the

    neck or upper arms, brought on by exercise and relieved by GTN. However, the pain may show relation to

    meals and be accompanied by transient dysphagia and symptoms of GORD.

    8.  Musculoskeletal pain 

    Pain is variable. Pain which varies with posture and movement of upper body, ± local tenderness overrib/cartilage are clues to musculoskeletal pain.

    You must exclude the following diagnoses in all cases as they are potentially fatal and need immediate Rx:

    1.  Acute coronary syndrome.

    2.  Aortic dissection.

    3.  Pneumothorax.4.  Pulmonary embolism.

    Key investigations

    1.  12 lead ECG.

    2.  Chest X-ray.3.  Blood tests: FBC, U&E, LFT, CRP, glucose, lipids, admission and 12 hour troponin.

    History: Dysphagia

    Written in April 2011 by Devvrat T. Katechia.

    Dysphagia

    Dysphagia is a difficulty in swallowing. It is important to clarify what a patient means when they say they have a“swallowing difficulty”. Painful swallowing is known as odynophagia, which can be due to malignancy but more

    commonly due to an infection such as candidiasis. Globus describes the sensation of having a lump in the throat and

    this must be distinguished from dysphagia.

    Dysphagia is caused by either:

    •  Neurological  pathology, which is commonly described as a functional problem. This can be further

    subdivided into higher or lower dysphagia depending on which part of the nervous system is affected.

     

    Structural  pathology where there is pathology involving either the lumen, the oesophageal wall (mural) ordue to external compression of the oesophagus (extrinsic). Dysphagia due to luminal pathology is commonlydue to a foreign body. (See table below for specific conditions). 

    Functional causes Structural causes

    Higher dysphagia

    Stroke

    Parkinson!s disease

    Myasthenia gravis

    Multiple Sclerosis

    Mural

    Oespophageal cancer

    Pharyngeal pouch

    Stricture: caustic or inflammatory

    (hence we ask about previous GORD

    and ulcers)

    Lower dysphagia

    Achalasia

    Diffuse oesophageal spasm

    Extrinsic

    Bronchial carcinoma

    Retrosternal goitreMediastinal mass

    Radiological investigations

    1. 

    Barium swallow: used in those with pathology high up in the oesophagus.

    2.  Endoscopy: useful in those with luminal or mural pathology. Tissue samples can also be obtained through

    this method for biopsy.

    3.  Videofluoroscopy:  useful in patients with suspected higher functional dysphagia.

    4.  Oesophageal manometry: used to measure the pressures in the lower oesophageal sphincter andperistalsis. Manometry is used for diagnosing motility disorders.

    Treatment of dysphagia will depend on the cause. It is important to obtain a very clear and thorough history from

    patients presenting with swallowing difficulties to aid the process of making a diagnosis.

    History: Falls and palpitations

    Written in April 2011 by Philip Chan.

    Common causes of falls in the elderly

    Falls are one of the most common presentations in elderly medicine and can be caused by a wide range ofpathologies. It is a serious matter that has a major impact on quality of life and has medical and social implications.

    •  Dysrhythmias including atrial fibrillation, supraventricular tachycardia and Stokes-Adams attacks. 

    •  Mechanical falls can occur if the patient has difficulty mobilising due to weakness or disability. Visual

    defects can also play a part in this. Often lack of mobility or poor vision will contribute to other potential

    causes of falls. 

    •  Peripheral neuropathy can cause loss of proprioception, contributing to falls. It can be a complication of

    long-standing diabetes. 

    •  Postural hypotension can cause syncope. It is diagnosed if there is fall of 20mmHg on lying to standing

    blood pressure measurement. Causes include hypovolaemia, autonomic insensitivity with increasing age

    and over-medication with hypotensive drugs. 

    • 

    Vasovagal syncope can occur after emotional stress, coughing, straining or standing up quickly. Prodromicsymptoms are often experienced, such as tinnitus, sweating, feeling hot, nausea and visual disturbances.  

    •  Epilepsy should be ruled out. 

    •  Multi-factorial falls occur when a combination of the above factors are present. This is often the case inelderly patients. 

    Key investigations, etc.

    •  Routine blood tests, including blood glucose.

    •  ECG. 

    •  24hr ambulatory ECG (Holter tape). 

    •  Echocardiogram. 

    •  Lying (or sitting) to standing blood pressure.

    •  Formal assessment of vision.

    • 

    Physiotherapist assessment of mobility.•  Formal neurological assessment including neuroimaging, if indicated.

    Causes of palpitations

    Palpitations describe an intermittent awareness of your own heartbeat. The heartbeat can be normal, slow or fast in

    rate, and regular or irregular in rhythm. It is useful to ask the patient to tap out the rate and rhythm of their palpitationsto help determine the underlying problem.

    •  Anxiety disorder is a term used to describe a range of psychiatric problems. It is a non-cardiac cause of

    palpitations that should be ruled out from the history.

    •  Tachycardia includes supraventricular tachycardia and ventricular tachycardia. Paroxysmal tachycardia 

    can occur due to junctional re-entry phenomena. 

    •  Bradycardia requires an increased stroke volume to maintain cardiac output. This can cause palpitations.  

    • 

    Atrial fibrillation is experienced as an irregularly irregular rhythm that can be slow or fast. The three maincauses of AF are: 1. Ischaemic heart disease, 2. Rheumatic heart disease and 3. Thyrotoxicosis. 

    •  Extrasystoles (premature beats) are often benign. They are felt by patients as “missed beats”.  

    •  Cardiomyopathy can cause dysrhythmias. 

    Key investigations, etc.

    •  Routine blood tests, including thyroid function tests.

    •  ECG. 

    •  24hr ambulatory ECG (Holter tape). 

    •  Exercise ECG. •  Echocardiogram.

    History: Haematuria

    Written in April 2011 by Kyaw Zayar Thant.

    Main differential diagnoses of frank haematuria and typical presenting histories

    1. 

    Bladder cancer

    Middle aged/elderly male, presenting with painless frank haematuria ± clots ± associated symptoms of

    malignancy (weight loss, anorexia, fever etc). Risk factors of smoking, occupational exposure to chemical

    carcinogens, e.g. rubber, textile, leather, paint industry.2.

     

    Renal cell carcinoma

    Middle aged/elderly male, presenting with triad of haematuria, loin pain and loin mass ± associatedsymptoms of malignancy (weight loss, anorexia, fever, etc).

    3. 

    Renal stones

    Male or female presenting with colicky loin pain radiating to groin ± haematuria (usually microscopic).4.

     

    UTI

    Female presenting with urinary frequency, dysuria, suprapubic pain and foul-smelling urine. 5. 

    Bleeding from prostate

    Elderly male with symptoms of LUTS and haematuria at end of stream with raised PSA.

    Key investigations

    1.  Urinalysis.2.

     

    MSSU

    a.  Microscopy: confirms haematuria and help to distinguish medical and surgical causes.

    b.  Culture and sensitivity: confirms UTI.

    3.  CT urography: identifies lesions in the kidneys and ureters.

    4.  Cystoscopy: identifies lesions in the bladder.5.  Routine bloods: FBC, U&E, LFT, CRP, Coag.

    History: Headache

    Written in April 2011 by Philip Chan.

    Classical presentations of headache

    Tension-type headache

    •  A gradual onset of global, tightening pain, of mild-moderate severity. The pain is non-pulsatile, not made

    worse by physical activity.

    •  This is the most common cause of headache.•  Most occur episodically but 3% of population have chronic TTH.

    Migraine

    •  A gradual onset of unilateral, pulsating, moderate-severe pain that is aggravated by exercise, typically

    lasting hours or days.•  Associated symptoms may include nausea, vomiting, photophobia and phonophobia.

    •  May or may not occur following an “aura”. An aura is a prodromic sensory phenomenon that ranges fromvisual disturbance (e.g. flickering lights or blind spots) to paraesthesia. Auras can occur hours or days beforea migraine and typically last 5-60 minutes.

    Cluster headache

    •  A rapid onset of unilateral, sharp, non-pulsatile pain, typically felt behind the eye, at the temple, or at the

    forehead.

    •  Pain is severe and can be described as the worst ever felt.•  Each episode lasts 45-90 minutes and characteristically occurs at the same time every day.

    Subarachnoid haemorrhage

    •  Classically described as a “thunderclap” headache that comes on suddenly and lasting only a few seconds.The pain is often the worst ever experienced.

    •  After the initial event, a less severe headache lingers for 1-2 weeks.•  Associated symptoms may include seizures, vomiting, stiff neck and photophobia.

    Meningitis

    •  A severe, throbbing, global headache with classical associated symptoms, such as fever, neck stiffness,altered consciousness, shock, Kernig!s sign (pain and resistance on passive extension of the knee, when

    the hip is in a flexed position) Brudzinski !s sign (hips flex when flexing the neck forward), focal neurological

    deficits and seizures.•  Meningococcal meningitis is associated with a non-blanching purpuric rash found anywhere on the body.

    Temporal arteritis

    •  Classically an elderly lady complaining of a severe, dull headache with scalp tenderness when she combs

    her hair and jaw ache when she eats.•  Associated with polymyalgia rheumatica.

    Idiopathic intracranial hypertension

    •  Classically a young, obese woman complaining of a two-week history of headaches that are worse in themorning and on lying down.

    History: Thyroid

    Written in April 2011 by Philip Chan.

    Hyperthyroidism

    Causes

    •  Graves! disease is the most common cause of hyperthyroidism (thyrotoxicosis). It is an autoimmune

    disease.

    •  Toxic multinodular goitre is common in the elderly.•  Toxic thyroid adenoma is a solitary benign tumour of the thyroid.

    SYMPTOMS SIGNS

    •  Weight loss.

    •  Increased appetite.

    •  Heat intolerance.

     

    Irritability.•  Tremor.

    •  Diarrhoea, palpitations, sweating,

    breathlessness, oligomenorrhoea or

    amenorrhoea, poor libido.

    •  Visual disturbance (in Graves! eye disease).

    •  Tremor.

    •  Hyperkinesis.

    •  Tachycardia or atrial fibrillation.

     

    Full pulse.•  Warm peripheries.

    •  Goitre.

    •  Thyroid acropachy, pretibial myxoedema.

    •  Exophthalmos, lid retraction (in Graves! eye

    disease).

    •  Lid lag can be present in any cause of

    hyperthyroidism and not just Graves! disease.

    Hypothyroidism

    Causes

    Primary hypothyroidism 

    •  Iodine deficiency is the most common cause of hypothyroidism worldwide, but is uncommon in the UK.

    •  Autoimmune disease such as Hashimoto!s thyroiditis.

    •  Iatrogenic due to treatment of hyperthyroidism with thyroidectomy or radioiodine therapy.

    Secondary hypothyroidism 

    •  Impaired pituitary function causes reduced production of TSH (thyroid-stimulating hormone). This canresult from, e.g. tumour, surgical or radiological damage.

    Tertiary hypothyroidism 

    •  Impaired hypothalamic function causes reduced production of TRH (thyrotropin-releasing hormone).

    SYMPTOMS SIGNS

    •  Lethargy.

    •  Weight gain.

    •  Cold intolerance.

    •  Goitre.

    •  Depression, constipation, menorrhagia or

    oligomennorhoea, loss of appetite, arthralgia,

    myalgia, poor libido.

    •  Mental slowness.

    •  Dry hair and hair thinning.

    •  Dry skin.

    •  Slow-relaxing reflexes.

    •  Bradycardia. 

    •  Cold peripheries, hypothermia, hypertension,

    oedema, carpal tunnel syndrome, ataxia.
