anterior muscle. It may be injured as a result of
pressure on the shoulder, either from a sudden
blow or by prolonged carrying of heavy objects.
It is often one of the nerves affected in brachial
neuritis and may also be damaged in diabetes
mellitus. Winging of the scapula results.

What is the likely diagnosis?
Lipoma
• Treatment is for cosmesis and consists of local
excision.
• Some individuals have multiple subcutaneous
lipomata; a biopsy may be required to exclude
neurofibromatosis in such patients.
• The patient with multiple, tender lipomata may
have Dercum's disease.
• A rare complication of lipomata is a liposarcoma.
What is shown at the arrow?
Ascending lymphangitis
• spreading of infection from its focus along regional
lymphatic vessels. Commonly, an abscess forms at the
regional nodes.
• commonly due to Streptococcus pyogenes; less often, to
Staphylococci. It presents as red blushes and streaks in
the skin corresponding to the inflamed lymphatics.
• Treatment is bed rest with the affected limb elevated.
• Penicillin V and Flucloxacillin
• Permanent lymphatic obstruction may develop resulting
in a persistent oedema. Repeated attacks cause chronic
lymphangitis.
What is this? It started life as a red
macule.
Erythema chronicum migrans
• Caused by Borrelia burgdorferi, Lyme
disease is common in the northeast United
States and in Wisconsin and Minnesota. It

mucocutaneous pigmentation - mainly, of the lips, buccal mucosa, genitalia,
hands and feet
•
•
Patients often present with small bowel intussusception before the age of 10
years.
•
The polyps themselves have a very low malignant potential. About 10-20%
of patients develop gastrointestinal carcinoma but this is thought to arise
from coexistent adenomas.
•
Patients have an increased risk of developing carcinomas of the pancreas,
lung, ovary and breast.
What are these lesions?

What is wrong with this chap? How
would you diagnose it?
Kaposis sarcoma
• Kaposi's sarcoma is a multicentric, malignant
neoplastic vascular proliferation, characterised
by the development of bluish-red nodules on the
skin. Sometimes there may be widespread
visceral involvement. It may metastasize to
lymph nodes.
• occurs in immunocompromised patients (e.g.
HIV positive patients, transplant patients)
• Diagnosis: skin biopsy
What is this?
keratoacanthoma
• Difficult to distinguish from SCC
• rapidly growing epidermal tumour that resembles squamous cell
carcinoma both clinically and histologically. It is believed to arise
from hair follicles.
• There is little evidence that keratocanthoma has malignant potential
• Trauma, viral infection, sun exposure, and chronic exposure to tar,
pitch and petroleum have all been implicated as aetiologic agents.
• Surgical excision is thought to produce less scarring than leaving
the lesion to resolve spontaneously.

diseases which are characterised by acute and chronic inflammation
of striated muscle.
• In dermatomyositis there is an accompanying dermatitis. The limb
girdle or proximal muscles are most severely affected but their bulk
is preserved beyond that expected from their weakness: this is an
important sign distinguishing this condition from a limb girdle
dystrophy.
• The aetiology is unknown but there is an association with HLA-B8
and HLA-DR3.
• Dermatomyositis in males over the age of 60 years may be
suggestive of an underlying systemic malignancy.
This 33 year old woman presented with fever, tachycardia,
chills, malaise and this hot tender lesion on her face. What

•
fever, tachycardia, chills, malaise
the infected area is red, hot, and tender e.g. red shiny plaque on face
local oedema which produces a raised border that is clinically diagnostic
the cellulitis spreads rapidly to involve uninfected skin
careful examination may reveal an abrasion through which the
streptococcus organism gained entry
an incision within the infected area exudes a thin pus

Porcelain gallbladder
• Porcelain gallbladder is a calcification of the
gallbladder believed to be brought on by
excessive gallstones but more studies are
necessary to determine the exact cause.
• Porcelain gallbladder often results in a diagnosis
of gallbladder cancer. The association with the
two is uncertain; gallbladder cancer is rare, but
is almost always found with porcelain
gallbladder. The prognosis is poor, in that the
gallbladder is usually asymptomatic until the
cancer has spread.
A 53-year-old man presented with low-grade fever and abdominal pain.
A tender, erythematous umbilical 3-cm mass is shown.
Strangulated umbilical hernia
• In a strangulated hernia, the blood supply of the
contents of the hernia, e.g. bowel or omentum, is
cut off. It is commonest at the neck of the sac.
The region becomes ischaemic and
subsequently gangrenous. Gangrene can lead
to perforation of the bowel with ensuing
peritonitis.
• When a loop of gut is strangulated, there will
also be intestinal obstruction.
• This 23 year old
woman is

A 65-year-old woman presented to the emergency department because a friend
was concerned that the patient was having a stroke. The patient was

Subconjuntival haemorrhage
• This presents as a bright red patch under the conjunctiva
following rupture of a small conjunctival vessel.
• It may arise spontaneously, following slight trauma, or as
a result of local congestion due to coughing or sneezing.
• In head injury, blood from a fracture at the base of the
skull may travel through the floor of the orbit and into the
subconjunctival space. The condition is usually
unilateral.
• Recurrent or bilateral subconjunctival haemorrhage
suggests hypertension or blood dyscrasias.
A 28-year-old woman complained of a foreign-body
sensation, pain and redness of the outer lower quadrant of
her left eye of 2-day's duration.
episcleritis
• unilateral in two-thirds of cases.
• It is benign and self-limited.
• 30% are associated with general medical conditions such as
collagen disease, herpes zoster, gout and syphilis.
• There are two types - simple and nodular. Simple episcleritis is
characterized by a very acute onset. It is mild, sectoral, recurrent
and resolves rapidly. The nodular form presents as a localised,
raised mobile area of inflammation near the limbus. The nodules
may be single or multiple and usually recur.
• About 15% of patients develop a mild iritis. Episcleritis is
distinguished from conjunctivitis by the localised response and the
lack of palpebral conjunctival involvement.
• oral non-steroidal anti-inflammatory drug (NSAID).
A 2- year-old girl presented with fever, erythema,
and swelling of the left upper eyelid. There were
no visual symptoms or proptosis.
periorbital cellulitis
• The findings shown are suggestive of acute
periorbital cellulitis, or more accurately, preseptal
cellulitis, an infection confined to the soft tissues
of the eyelid. Bacteriology of preseptal cellulitis
includes those bacteria that cause sinusitis
(Haemophilus influenzae, Streptococcus
pneumoniae, Moraxella catarrhalis, S
pyogenes); skin flora from trauma
(Staphylococcus aureus and group A
Streptococcus); and idiopathic (H influenzae
type B, S pneumoniae). (L.S.)
A 20-year-old man presented with a brief loss of consciousness
following a fall from standing height. He had a brief lucid interval then
became progressively less responsive. This is his CT scan
Extradural haematoma
• The characteristic appearance of a CT of
an extradural haemorrhage is of a
biconvex, lozenge shaped area of
increased density.
• Spread is limited by the adhesion of the
dura to the skull. A midline shift with
compression of the ipsilateral ventricle
may be apparent.
A 25-year-old man was brought to the emergency
department after having been hit in the left lateral chest

emergency situation
A 37-year-old homeless man presented to the emergency
department with a 3-week history of neck pain that had

Subluxation of c1 on c2
• Cervical subluxation is a flexion injury. There is no bony
damage but the soft tissues are extensively damaged
and the posterior ligaments torn. The affected vertebra
hinges forward on the one below, opening up the
interspinous space posteriorly then falls back again.
• Radiologically there may be an increased gap between
the spines of affected vertebra, but the film often
appears normal - flexion radiology may be required to
demonstrate the instability.
• Treatment is usually a collar for six weeks. However, if
there is persistent instability a posterior spinal fusion
may be required.
What is wrong with this girl…be
specific!
Bell’s palsy
• It is a lower motor neurone palsy usually
diagnosed by exclusion. Typically, presentation
is with facial distortion, loss of taste, hyperacusis
and a watery eye.
• Bell's palsy was previously considered as an
idiopthic lower motor neurone nerve palsy but
there has been increasing evidence to suggest
that the main cause of Bell's palsy is latent
herpes viruses (herpes simplex virus type 1 and
herpes zoster virus), which are reactivated from
cranial nerve ganglia

the head is tilted towards the affected side
• CNIV is thinnest and has the longest intracranial course
damaged easily by stroke and trauma
What is wrong with these miserable

Myasthenia gravis
• Myasthenia gravis is an acquired autoimmune disorder
characterised by weakness, typically of the periocular, facial, bulbar,
and girdle muscles.
• Associated with serum IgG antibodies to acetylcholine receptors in
the postsynaptic membrane of the neuromuscular junction.
• Classically, the muscles are easily fatigued.
• It affects 5 people in every 100 000.
• Non-thymoma cases have a peak incidence at 10-30 years and
again, at 60-70 years of age; those associated with thymoma have a
peak incidence at 40-50 years of age.
Diff diagnosis
• Lambert-Eaton syndrome - muscles are
not fatiguable - contraction leads to
increased strength - reflexes are
diminished
• congenital myasthenia
• botulism
• motor neurone disease (MND) - note that
eye is very rarely involved in MND
Myasthenia gravis
•
Exacerbated by: exercise, barbituates, steroids
•
improvement in strength after administering a short-acting anticholinesterase drug,
for example, edrophonium chloride.
•
acetylcholine receptor antibodies
•
Management
–
–
–
–
–
oral anticholinesterase medication, e.g. pyridostigmine or neostigmine (symptomatic
improvement).
if there is life-threatening or respiratory weakness developing in treated patients, then this
usually requires immediate control of the airway, treatment of any underlying infection, and a
course of plasma exchange
thymectomy - required if there is a thymoma because of the risk of local infiltration. Also
occasionally undertaken in other non-thymoma patients with myasthenia
immunosuppression with corticosteroids +/- cytotoxic agents is also highly effective in
inducing remission of disease and may be necessary preliminary to surgery in patients with
severe disease.
plasma exchange
Lambert eaton
• Lambert-Eaton myasthenia is a presynaptic
myasthenic syndrome characterised by impaired
release of acetycholine from nerve terminals.
• 60% of patients have small cell lung carcinoma.
• Electromyography shows increased evoked
potentials after repeated galvanic stimulation
(the opposite occurs in myasthenia gravis).
Symptoms improve with exercise
Right sided horners syndrome
• slight ptosis
• pupillary miosis:
– due to paralysis of the sympathetically innervated

What is wrong with this chap? Ignore
the white thing I don’t know what that is
hydrocephalus
• Communicating hydrocephalus
– obstruction to CSF flow from outside the ventricular
system, usually in the subarachnoid space. All the
ventricles show a generalised dilatation on a CT scan.
It is safe to perform a lumbar puncture
• Non-communicating hydrocephalus
– obstruction to CSF flow within the ventricular system.
Fluid accumulates proximal to the site of the blockage
causing dilation.
Management of hydrocephalus
– The cause of hydrocephalus should be eliminated if possible - e.g.
colloid cysts of the 3rd ventricle, intraventricular meningioma, other
obstructive causes.
– Otherwise, relieve pressure by shunting, or if the patient is rapidly
deteriorating, by draining the ventricle directly.
– Endoscopic third ventriculostomy has become a more recent, and
important, treatment option for occlusive hydrocephalus associated with
aqueductal stenosis or space-occupying lesions of or around the
posterior third ventricle and upper brainstem (1,2):
– this procedure appears to be more successful in adults than in young
children
– it is efficacious in both previously shunted and non shunted patient
– complication and mortality rates compare favorably with those for
shunts
– has also been increasingly used as an alternative treatment option for
shunt complications
– Lumbar puncture may be used to relieve pressure in an acute
communicating hydrocephalus.
NPH
• Normal pressure hydrocephalus is a form of
communicating hydrocephalus in which the
intracranial pressure, as measured by lumbar
puncture, is normal or intermittently raised.
• Failure to reabsorb CSF is compensated by
reduced production.
• gait apraxia
• progressive dementia with memory loss
• sphincter disturbance resulting in incontinence

infarcted region in the right hemisphere.
Haemorrhage is evident from its onset on
CT scanning.
• What is this??
• What factors
predispose to this
condition?
• How would you
manage?
Subdural haemorrhage
• The characteristic picture of a CT scan of a
subdural haemorrhage is one of a biconcave,
concentric shaped, area of increased density
spreading around the surface of the cerebral
hemisphere. The contralateral ventricle may
dilate owing to obstruction at the foramen of
Munro.
• After 10-20 days, the subdural haematoma
becomes isodense with brain. Later it becomes
relatively hypodense.
Subdural haematoma
•
Subdural haemorrhages result from rupture of cortical bridging veins. These
connect the venous system of the brain to the large intradural venous
sinuses and lie relatively unprotected in the subdural space.
•
any factor that stretches the bridging veins:
– cerebral atrophy, e.g. elderly
– low CSF pressure after shunting, for example for long- standing hydrocephalus
or a fistula
•
•
alcoholism
coagulation disorder or anticoagulation therapy
•
patients in whom conscious level is depressed:
– evacuate haematoma through 2-3 burr holes, and irrigate cavity with saline
– nursing in the head down position is recommended to prevent recollection
•
patients in whom conscious level is not depressed:
– consider conservative measures - steroid treatment over several weeks
How do you diagnose and treat this

Glue ear
• Secretory otitis media, or `glue ear', is the most frequent
cause of hearing problems in children.
• accumulation of serous or viscous fluid within the middle
ear
• pain
• conductive hearing loss
• dull / dark blue/ grey appearance of tympanic membrane
• Rinne's test negative; Weber's test - sound heard
loudest in the deafer ear.
Grommets
• The function of a grommet is to ventilate the
middle ear, rather than drain it. Grommets thus
replace the function of the blocked eustachian
tube in glue ear and improve hearing.
• use of grommets in glue ear (otitis media with
effusion) offer only small benefits
• potentially adverse effects on the tympanic
membrane are common after grommet insertion
– ears treated with grommets had an additional risk for
tympanosclerosis one to five years later

This 34 yr old male patient presented with
malaise, weight loss, apthous ulcers and this
intensely itchy skin rash
Dermatitis herpetiformis
• Dermatitis herpetiformis is an intensely itching subepidermal
vesicular blistering condition that usually develops in the 3rd or 4th
decade. Men>women.
• intensely pruritic, vesicular rash chiefly affecting the extensor
surfaces of shoulders, buttocks, knees, forehead and scalp, sparing
the mucosae. Small blisters are rarely seen since they are rapidly
excoriated, leaving raw papules. Vesicles are frequently grouped, as
those of the true herpes virus, hence the name 'herpetiformis.‘
• About 90% of patients with dermatitis herpetiformis will have coeliac
disease
• Tx - dapsone, in doses of 25-100 mg/day for itching
• Gluten free diet
• Topical steroids

– cryotherapy
• HAEMORRHOIDECTOMY
• LORD’S STRETCH!!!! ANAL DILATATION UNDER GA
HOW WOULD YOU TREAT THIS?
HYDROCOELE
•
Tx childhood hydrocoeles only if they persist after 1 yrs old. The procedure
is as for an inguinal hernia - open the sac, inspect the testis for
abnormalities, ligate and divide the patent processus vaginalis.
•
In adults, primary hydrocoeles may be treated:
•
conservatively - reassure the patient and provide a scrotal support.
•
by aspiration - use a sterile needle and syringe. Clear, pale yellow fluid
should be drained; fluid that is bloodstained suggests trauma or other
underlying pathology. Following aspiration, the testis should be palpable. A
sclerosant such as phenol may then be injected to stop fluid from
reaccumulating, otherwise, periodic aspiration may be necessary. A
hydrocoele should not be tapped if there is any suspicion of tumour - in the
case of a tumour, aspiration may result in spread of malignant cells.
•
by operation - if the diagnosis is in doubt, the hydrocoele is large, or fluid
repeatedly reaccumulates after drainage. Once the fluid has been removed,
the testis is examined for abnormalities.
Neuropathic ulcer (diabetes pt)
What is this?
• How would the

Ruptured appendix
•
Acute appendicitis is usually a clinical diagnosis
•
•
•
•
•
full blood count - leukocytosis is generally present
urea and electrolytes - assessment of dehydration
pregnancy test
serum amylase - if pancreatitis suspected
abdominal radiology - helpful to distinguish:
–
–
–
–
–
volvulus
intussusception
renal stones (90%)
gallstones (10%)
localised ileus
•
Generally, urine analysis is unhelpful in differentiating appendicitis from a urinary tract
infection.
•
There is no place for barium enema in the diagnosis of appendicitis. Occasionally,
ultrasound and CT scanning are used to investigate suspected appendicitis where the
story is atypical. US exclude gynae pathology (ovarian cyst)

Myxoedmea
MANAGEMENT OF ASCITES
• TENSE ASCITES
– therapeutic paracentesis of 4-6 litres
– plasma volume expansion with albumin (6g/litre of ascitic fluid removed)
• NON-TENSE ASCITES
– bed-rest, reduced salt intake, and spironolactone (50-100 mg per day).
A fall in weight of approximately 0.5 kg per day should be aimed for.
– spironolactone is gradually increased to 300 mg per day and then, if
necessary, frusemide is added, but only once the spironolactone has
reached its maximum dose.
– loop diuretics may precipitate the hepatorenal syndrome
– If a patient has malignant ascites then large doses of frusemide may be
required to control ascites.
– A Le Veen shunt (peritoneo-venous) may be useful in refractory cases.

Marasmus
• Marasmus is failure to grow associated with emaciation and fair
appetite. It may be defined in terms of weight, for example less than
60% of that expected for age.
• Marasmus generally occurs in infants up to one year. In the
developed world it is found in infants who are born undernourished
or are recovering from a severe chronic illness, especially those
affecting the bowel.
• In developing countries this condition commonly is associated with
failure of lactation due to poor nutrition of the mother.
• Note that marasmus is an adaptive response to poor nutrition.

Angiodysplasia
• Colonic angiodysplasia is a common cause of acute or chronic
rectal bleeding and iron deficiency anaemia.
• Angiodysplasias are tiny - 1-5 mm in diameter - hamartomatous
capillary lesions in the colonic wall which produce bleeding out of
proportion to their size. They are believed to be acquired, possibly
as a result of tension on the veins where they pass through the
muscularis.
• colonscopy: may visualise lesion
• Treatment:
• electrical coagulation via the colonoscope
• resection of segment of colon if the above is unsuccessful

Beriberi
• severe prolonged deficiency of vitamin B1 (thiamine)
• Beriberi was discovered in the seventeenth century in
Java by the Dutch physician Jacobius Bonitus. The
name means "sheep" in the local language; this
describes the characteristic gait of patients.
• Today, beriberi is confined to the poorest parts of Asia
where little else is eaten except polished rice.
• Prevention of beriberi requires:
• a more varied diet, including legumes and pulses
• thiamine supplementation of rice

MANAGEMENT
What is this ECG of a 23 year old man with
episodes of tachycardia showing? How would you
manage?
Wolf Parkinson White
• The two complications of WPW are the development of an AV reentrant tachycardia or atrial fibrillation.
• An AV re-entrant tachycardia is managed as for any other
supraventricular tachycardia (see linked item)
• Atrial fibrillation secondary to WPW should not be treated with AVblocking drugs such as verapamil and digoxin. The simplest method
of terminating atrial fibrillation is cardioversion. If drugs are to be
used then they must slow conduction in the accessory pathway e.g.
intravenous sotalol, flecainide, amiodarone. These drugs will slow
the ventricular response and will often result in restoration of sinus
rhythm.
• For prevention of atrial fibrillation drugs such as oral sotalol and
amiodarone are effective.

• Rarely renal carcinoma can compress L
testicular vein and cause a L sided
varicocoele
SAH
• Subarachnoid haemorrhage accounts for
about 6% of cerebrovascular disease with
an annual incidence of about 1 per 10,000.
It is bleeding from intracranial vessels in
the subarachnoid space. Occasionally, the
arachnoid layer gives way and a subdural
haematoma develops.

CMV retinitis
• Cytomegalovirus (CMV) retinitis occurs in immunocompromised
patients.
• 'pizza pie' fundus:
– retinal spots which are the result of superficial retinal infarction
– also flame shaped haemorrhages
• associated with a low CD4 count
• Asymptomatic or sudden (and untreatable) visual loss
• Other manifestations of cytomegalovirus infection in these patients
includes encephalitis, pneumonitis, and diffuse gastro-intestinal
involvement.
• Treat with ganciclovir (or foscarnet in cases of reduced sensitivity to
ganciclovir).
Roth spots
• These are superficial retinal
haemorrhages with red edges but pale or
white centres. These may be seen in a
variety of conditions including infective
endocarditis. They are not pathognomonic
of any particular disease.
• Also seen in leukaemia
Loosers zones
• Osteomalacia
• This is a pseudofracture seen in osteomalacia. On x-ray,
it appears as a thin, translucent band, about 2 mm in
width, which runs perpendicular to the surface of the
bone extending from the cortex inwards.
• incomplete stress fractures which heal with callus lacking
in calcium
• pubic rami, the necks of the humeri and femora and at
the axillary edge of the scapulae
• Oral kaposi’s sarcoma
• Wickham’s striae
• Lichen planus
• The oral lesions have a radiating velvet, white or gray
appearance, most commonly in a reticulated pattern.
This represents the "lace-like" network of linear
subepithelial fibrosis found in these lesions. The buccal
and glossal mucosas are most commonly affected,
however, lesions can also be found in the palate and
gingiva (erosive gingivitis).
Central retinal artery occlusion
• The retina has become milky because of
infarction. Tissue necrosis makes the tissue lose
its normal transparency.
• Cherry-red spot
• The red-orange color of the fovea appears in
stark contrast to the surrounding milky retinal
edema. Called a "cherry-red spot," it results from
the fact that the fovea contains only the
photoreceptor layer, which is spared because it
is nourished by the choroidal circulation rather
than the retinal circulation.
Central retinal vein occlusion
• The patient presents with painless loss of vision,
often mixed with sparkles, that may be sudden
or evolve over hours to days.
• Systemic hypertension is the most common
cause; hyperviscous and hypercoagulable states
must also be considered.
• Numerous haemorrhages seen – splattered with
blood
