max flashcards

Can you separate each flashcard for each disorder. And then within each disorder on the different subheadings e.g. symptoms. So like at the top of each flashcard just right 'SUPRACONDYLAR FRACTURE' then write management or symptoms or whatever it is.

UPPER LIMB:

WEEK 1:

BICEPS TENDON RUPTURE

Symptoms:

 - Bruising tracking down forearm due to gravity

 - Bulge near shoulder due to biceps brachii contracting upwards causing the bulge as its distal attachment has been disrupted

 

Problems:

 - Weakened elbow flexion (of supinated arm) and supination (of flexed elbow)

 

Tests:

 - Tears can be confirmed with soft tissue imaging modalities e.g. ultrasound and MRI

 

Management:

  1. Conservative - not ideal for either proximal or distal tears (unless partial - rare)

  2. Medical - analgesia and anti-inflammatories

  3. Surgery - aim to reattach biceps tendon

 

Additional information:

 - Proximal ruptures are more common than distal

 - Proximal ruptures are most common over the age of 60 years (degenerative)

 - Distal rupture is usually an injury in younger people associated with heavy lifting or sports

 

SUPRACONDYLAR HUMERUS FRACTURE:

Symptoms:

 - Visible deformity

 

Problems:

 - Median nerve and brachial particular at risk (lie just anterior)

 

Tests:

 - Median nerve examination: sensory (tap over distal palmar aspect of digit 2) and physical (e.g. pen touch test - testing abductor pollicis brevis)

 - Radiograph of elbow (2 views)

 

Management:

 - Neurovascular compromise requires emergency attention and likely surgery

 - Undisplaced fractures are stable and can be treated with cast immobilisation for about 3 weeks

 - Displaced fractures require reduction via possibly pinning plus cast immobolisation

 

Possible risks of treatment:

 - Malunion: resulting in cubitus varus (could lead to ulnar nerve problems)

 - Ischaemic contracture due to damage to brachial artery

 - Damage to the ulnar, median or radial nerve (most commonly injured is anterior interosseous nerve, followed by radial and then ulnar nerve)

 

MALUNION AFTER SUPRACODYLAR HUMERUS FRACTURE:

Symptoms:

 - Left cubitus valgus deformity

 - POTENTIALLY: ulnar claw

 

Problems:

 - Ulnar nerve function disruption

 

Tests:

 - Ulnar nerve examination: sensory (tap over distal palmar aspect of digit 5) and motor (Froment's test + splaying of fingers against pressure)

 - MRI, plus radiograph/ultrasound

 

Management:

 - Ulnar nerve transposition surgery

 

Additional information:

 - Ulnar 'paradox': seemingly more pronounced claw in distal ulnar nerve damage despite reduced functional losses

 

WEEK 2:

LATERAL EPICONDYLITIS:

Symptoms:

 - Pain around outer aspect of elbow

 - Weak and painful grip

 

Tests:

 - Active wrist extension against resistance

 - Power grip test

 

Management:

  1. Conservative - physiotherapy, splint, ice, rest

  2. Medical - NSAIDs

  3. Intervention - steroid injections

  4. Surgery - very rare (only considered for professional athletes)

 

MEDIAL EPICONDYLITIS:

Symptoms:

 - Pain around inner aspect of elbow

 - Weak and painful grip

 

Tests:

 - Active wrist flexion against resistance

 - Power grip test

 

Management:

  1. Conservative - physiotherapy, splint, ice, rest

  2. Medical - NSAIDs

  3. Intervention - steroid injections

  4. Surgery - very rare (only considered for professional athletes)

 

HUMERUS FRACTURE:

Symptoms:

 - Bruising and swelling mid arm

 - POTENTIALLY - wrist drop

 

Problems:

 - Disrupted radial nerve function

 - Weakened power grip

 - Damage to profunda brachii artery

 

Tests:

 - Radial nerve function: sensory (tap skin over first dorsal interossei) and motor (wrist and finger extension against resistance)

 - Radiograph

 

Management:

  1. Conservative - humeral brace (allows a degree of traction on the fracture to maintain alignment)

  2. Medical - analgesia and anti-inflammatories

  3. Surgical - open reduction and internal fixation

 

Risks of treatment:

 - Infection, bleeding, complication of general anaesthetic, damage to radial nerve and profunda brachii artery in spiral groove

 

Additional information:

 - Thrower's fracture - transverse fracture of proximal humerus often seen in amateur cricket players due to poor training/technique

 - Can also have fracture of surgical neck of humerus

 

SHOULDER DISLOCATION:

Symptoms:

 - Severe pain in shoulder and unable to move arm

 - Abnormal contour compared to other side (acromion appears more prominent, and the deltoid appears to have reduced bulk laterally)

 - Inability to abduct shoulder past 40 degrees

 

Problems:

 - Axillary nerve damage (rarely axillary artery)

 - Musculocutaneous nerve is second most likely affected nerve (but very rarely)

 - Wasting of the deltoids, leads to squaring of the shoulder

 

Tests:

 - Axillary nerve function: sensory (regimental badge)

 - Potentially tests lateral cutaneous nerve of the forearm (terminal branch of musculocutaneous)

 - Radiograph (2 views)

 

Management:

 - Reduction

 - Document sensory loss (or lack thereof) BEFORE and after reduction

 - Recurrent dislocation may require surgical intervention

 

Problems of treatment:

 - Damage to axillary nerve (rarely musculocutaneous nerve) - will likely recover

 

Additional information:

 - 90% are antero-inferior

 - Posterior dislocations may happen during epileptic seizures /electrocutions or a forceful arrest with arm behind back

 - Inferior movement of dislocations happen due to lax capsule inferiorly and lack of muscles/tendons

 - Coracoacromial arch prevents upward dislocation occurring frequently

 - Recurrent dislocations may stretch and damage the capsule and capsular ligaments + glenoid labrum or humeral head

 - Other possibilities are fracture of the clavicle, acromioclavicular joint disruption or humeral fracture

 - Axillary nerve can also be injured by intramuscular injections into deltoid, or fractures of the surgical neck of the humerus

 

WEEK 3:

BREAST CANCER:

Symptoms:

 - Nipple contraction (caused by tethering by shortening of the suspensory ligaments which normally fix breast tissue to the skin and underlying fascia - causes elevation, dimple formation or retraction of the nipple)

 - P'eau d'orange (due to cutaneous lymphatic oedema - local involvement of lymphatic drainage in the breast)

 

Tests:

 - Careful examination of the axilla - metastatic spread of breast cancer to the axillary lymph nodes is common (cannot assess metastasis to lymph nodes behind sternum)

 

Management:

 - Mastectomy and axillary node clearance

 

Problems with treatment:

 - Infection, bleeding, DVT, death + lymphedema of the upper limb

 - Damage to long thoracic nerve, serratus anterior palsy, winging of the scapula, difficulty completing full abduction

 - Loss/reduction or paresthesia of cutaneous sensation including medial arm

 

Additional information:

 - Many breast cancers are missed by failure to examine axillary tail of the breast

 - Breast cancer can also happen in biological males (usually men over 60)

 

ERB'S PALSY: C5/6

Causes:

 - Forced separation of head from shoulder (e.g. obstetric injury, falling on shoulder - commonly off a motorbike)

 

Symptoms:

 - Waiter's tip position - adduction at the shoulder , internal rotation at the shoulder, pronation of the forearm, extension at the elbow and flexion at wrist

 

Tests:

 - Sensory function: press in C5/6 dermatomes - lateral arm, forearm and thumb

 - Motor function: biceps jerk C5/6

 

Management:

 - Physiotherapy (many gain normal function over 3-4 months)

 

KLUMPKE'S PALSY: C8-T1

Causes:

 - Hyperabduction traction injury

 - Penetrating trauma to posterior triangle

 - Pancoast tumour

 - Thoracic outlet syndrome e.g. cervical rib

 

Symptoms:

 - Ulnar claw-like hand, but with hyperextension of all MCPJs due to unopposed action of the extensors + flexion at all IPJs

 

Tests:

 - Sensory function: press in C8/T1 dermatomes: little finger, medial forearm and medial arm

 - Pen touch test (unable to do with Klumpke's; able to do with ulnar nerve palsy - abductor pollicis brevis)

 - Froment's test (unable to do due to loss of adductor pollicis - instead patient will try to compensate with flexion)

 

ROTATOR CUFF TEAR:

Risk factors:

 - Largely caused by normal wear and tear that goes along with aging, people over 40 are at greater risk

 - People who do repetitive lifting are at greater risk

 - Athletes are especially vulnerable to overuse tears, particularly tennis players and baseball pitchers

 - Painters, carpenters, and others who do overhead work also have a greater change of tears

 - Although overuse tears caused by sports activity also occur in younger people, most tears in young adults are caused by a traumatic injury, like a fall

 

Symptoms:

 - Pain in right shoulder

 - Difficulty raising arm above her head

 

Tests:

 - Full range of movement must be assessed - abduction, flexion, extension, internal and external rotation

 - Full range of movement restricted suggests adhesive capsulitis

 - Inability to initiate abduction implies tear of supraspinatus

 - Painful arc suggests supraspinatus tendinitis and/or subacromial bursitis

 - All movement a little painful but not very restricted suggests osteoarthritis

 - Radiograph to test osteological pathology, MRI to test soft tissue problem

 

Management:

 - For tendinitis/bursitis: conservative (physiotherapy) or medication (analgesia + anti-inflammatories) or steroid injection

 - For partial/full thickness tear: conservative/medical management first then surgical if required e.g. arthroscopic repair / open repair

 

WEEK 4:

DISTAL RADIAL FRACTURES: (Colle's / dinner fork)

Causes:

 - Falling on an outstretched hand (FOOSH)

 

Symptoms:

 - Pain and deformity around wrist

 

Tests:

 - Neurovascular examination: radial + ulnar pulses, cutaneous sensation (notably ulnar nerve), motor function e.g. pen touch, Froment's, wrist extension

 - Radiograph

 

Management:

 - Immediate analgesia

 - Manipulate and immobilize with plaster cast applied once fracture reduced

 

Problems with treatment:

 - Immediate neurovascular complications

 - Longer term: malunion, osteoarthiritis, rupture of extensor pollicis longus (from Lister's tubercle), chronic pain

 

Additional information:

 - Comminuted, displaced fracture of the distal radius involving the articular surface + dorsal displacement of the distal portion

 - Common fracture with osteoporosis - more common in older females

 

SCAPHOID FRACTURE:

Causes:

 - FOOSH

 

Symptoms:

 - Pain and swelling around the wrist (specifically tenderness over anatomical snuffbox)

 

Problems:

Tests:

 - Tinel's test (tap over median nerve in carpal tunnel)

 - Phalen's test (hold wrist flexed against eachother)

 - Median nerve test: sensory (tap over distal palmar aspect of digit 2) and motor (pen touch test + negative for Hand of Benediction as median nerve injury is too distal)

 - Ultrasound/MRI

 

Management:

  1. Conservative - splinting

  2. Medical - NSAIDs or corticosteroid injections int carpal tunnel

  3. Surgical - open or endoscopic release of flexor retinaculum in cases of pronounced nocturnal pain

 

Problems with treatment:

 - Bleeding, infection, median nerve damage, tendon injury, recurrence of CTS

 

DUPUYTREN'S CONTRACTURE:

Risk factors:

 - Smoking

 - RARELY finger loss

 

Additional information:

 - Most often reported in Caucasians of North-Western European descent

 - Some family history link

 - Related conditions: tenosynovitis - inflammation of the flexor tendons and synvoial sheaths may occur with chronic repetitive use

 

THORAX:

WEEK 1:

DAMAGE TO SPINAL ACCESSORY NERVE:

Risk factors:

 - Damage during cervical lymph node biopsy

 

Symptoms:

 - Weakness of trapezius

 - Loss of muscle bulk at the neck

 - Drooping shoulder (depressed and laterally displaced)

 - (there is no cutaneous sensory loss)

 

Tests:

 - Turn head against resistance (test SCM)

 - Ultrasound

 

Management:

 - Conservative management (orthosis)

 - Physical repair

 - Surgical repair

 

SPINAL STENOSIS:

Causes:

 - Bony structures e.g. facet oseophytes or posterior vertebral body osteophytes

 - Soft tissue structures e.g. herniated or bulging discs / hypertrophy or bulking of the ligaments

 - Trauma, tumours, Paget disease of bone

 

Symptoms:
 - Long history of neck pain and lower back pain

 - Some pins and needles in both hands

 - Increasing clumsiness recently with progressive weakness

 - Suddenly unable to walk

 

Tests:

 - Radiograph (signs of degenerative change in cervical spine - narrowing of the IV-disc spaces and degenerative changes at the facet joints

 - CT (some of the vertebra are wedge-shaped and have lost height)

 - MRI (posterior extrusion of intervertebral discs + overall narrowing of the spinal canal)

 

Management:

  1. Conservative - patient education, analgesia, exercise/physiotherapy, epidural steroid and/or anaesthetic injections

  2. Surgical - laminectomy, spinal fusion, minimally invasive surgery

 

Problems with surgery:

 - No treatment: may get worse or spontaneously improve -> some symptoms might become permanent

 

Additional information:

 - Spinal stenosis is a condition where a portion of the spinal canal narrows at which it can exert pressure on the spinal cord

 - Men more affected than women

 - Prevalence increases with age

 - Acquired cases more common than congenital ones

 - Most common cause is osteoarthritis

 

PNEUMOTHORAX:

Causes:

 - Subclavian +IJV catheterisation can be cause pneumothorax and haemothorax with poor technique

 - (IJV catheterisation is more commonly implicated with arterial puncture + chylothorax)

 

Symptoms:

 - Sharp pain on breathing in

 

Tests:

 - Radiograph - loss of lung markings in upper zones

 

Management:

 - Provide analgesia, have oxygen easily available

 - Observe

 - Inspiration/expiration CXR performed multiple times

 - If it progresses and he becomes symptomatic: needle aspiration and chest chain if aspiration unsuccessful

 

Additional information:

 - IJV catheterisation on right is preferable as lymphatic damage drains just upper right quadrant of body

 

WEEK 6:

PANCOAST TUMOUR:

Risk factors:

 - Smoking

 

Symptoms:

 - Persistent cough with occasional streaks of blood

 - Breathless on exertion

 - Drooping of his right eyelid + constricted right pupil + anhidrosis on right side (Horner's syndrome)

 - Pain down the inner side of his right arm

 - Weight loss

 

Problems:

 - Disruption of cervical sympathetic chain to the head (stellate ganglion)

 - Lower brachial plexus involvement

 - Phrenic nerve palsy

 

Tests:

 - Biopsy and/or bronchoscopy

 - CT, PET

 

Management:

 - Management of symptoms and support for diagnosis

 - Chemoradiotherapy

 - Surgery

 - Palliative care

 

Additional information:

 - Lung cancer does not usually cause notable symptoms until it's spread through the lungs or into other parts of the body

 - Most common cause of cancer death in the UK (21%)

 

ASPIRATION:

Symptoms:

 - Cough and difficulty breathing

 - Increased respiratory rate

 - Nasal flaring

 - Normal oxygen saturations

 - Reduced breath sound on auscultation on the right

 

Problems:

 - Airway obstruction, leading to lobar collapse

 - If incomplete obstruction, may result in lobar pneumonia

 

Tests:

 - Radiograph

 

Management:

 - Bronchoscopic retrieval

 

Additional information:

 - Likely object has passed into right inferior lower lobe: the right main bronchus is wider, shorter and more vertical than the left, so when a patient is standing up the object would pass here

 - If patient was in supine position, object may have passed into apical segment of lower lobes high up on the posterior chest wall (often site of aspiration of gastric contents when vomiting whilst lying down)

 

PNEUMONIA:

Causes:

 - Community acquired/hospital acquired

 - Bacteria such as streptococcus pneumoniae, haemophilus influenzae

 

Symptoms:

 - Productive cough, shortness of breath and a fever

 - Reduced breath sounds in some lobes of the lungs

 - Percussion - dull in these same lobes

 

Problems:

 - Worsening of infection

 - Empyema (pus in pleural cavity)

 - Sepsis + septic shock + death

 

Tests:

 - Full auscultation examination must be completed (including listening at the back).

 - Radiograph: heart borders may be obscured due to consolidation of some lobes of the lungs + obscured diaphragmatic recess + prominent mediastinal lymph nodes can be seen consistent with reactive lymphadenopathy

 - Blood tests

 

Management:

 - Oxygen, broad spectrum antibiotics and IV fluids

 

WEEK 7:

CARDIAC ISCHAEMIA:

Risk factors:

 - Family history, male, smoking, obesity, raised cholesterol, hypertension, diabetes

 

Symptoms:

 - Sudden onset of crushing central chest pain radiating to his left arm

 

Problems:

 - Significant myocardial infarction and arrythmia - could cause sudden cardiac death

 

Tests:

 - Respiratory and cardiovascular examination

 - Vital signs: heart rate, blood pressure, respiratory rate, oxygen saturations

 - ECG: 12-lead ECG obtained using 10 electrodes

 - Radiograph

 - Cardiac monitor

 - Coronary angiography

 

Management:

 - Aspirin (ASAP)

 - Pain relief

 - Oxygen therapy (if oxygen saturation <90%)

 - Antiplatelet therapy

 - Intravenous nitrate

 - Coronary artery stenting

 - Coronary artery bypass grafting (e.g. radial artery, long saphenous vein, internal thoracic artery

 

CARDIAC TAMPONADE:

Symptoms:

 - Severe shortness of breath

 - Distended external jugular vein

 - Pericardial effusion: Beck triad of cardiac tamponade - low blood pressure, muffled heart sounds and distended neck veins

 

Problems:

 - Fast accumulation of fluid does not allow pericardium to stretch as much to accommodate large volumes of fluid (opposite for slow gradual accumulations)

 - Can lead to severe impaired cardiac output and death

 

Tests:

 - Radiograph

 - Ultrasound (can see pericardial fluid)

 

Management:

 - Oxygen and constant monitoring

 - If small, asymptomatic, then conservative management is usually favoured (not here)

 - In cases where effusions are recurrent and symptomatic the pericardial fenestration can be performed (from under xiphisternum angled upwards)

 

Additional information:

 - Symptoms relate to impaired cardiac function due to intrapericardial pressure approximating intracardiac pressure leading to an impaired filling of low-pressure chambers, particularly the right atrium

 

AORTIC DISSECTION:

Risk factors:

 - Hypertension

 - Atherosclerosis

 - Connective tissue disease

 - Male

 

Symptoms:

 - Sudden onset chest pain that is 'tearing' and goes to the neck and down the back

 - Some difficulty speaking (damage to recurrent laryngeal nerve)

 - Tachycardia

 - Right sided radial and carotid pulses are weaker than the left (occurs when dissection flap involves origin of brachiocephalic artery)

 

Problems:

 - Aortic rupture (mortality of 80%)

 - May be indicated by hypotension, syncope, haemothorax, or retroperitoneal haemorrhage

 - Impacts on branches e.g. coronary arteries

 - Tamponade if rupture occurs in aortic root

 - Risk of ischaemic stroke + pulse deficit

 

Tests:

 - CT angiograms using iodine based contrast medium injected intravenously

 - Transthoracic echocardiography

 

Management:

 - Immediate: high-flow oxygen, IV access, continuous observations, immediate control of blood pressure, analgesia

 - Surgical: Type A dissections require open surgery to prevent aortic rupture and carry worse prognosis than Type B dissections + involves removal of ascending aorta with or without aortic arch and replacement with synthetic graft (branches of aortic arch involved in the dissection may require reimplantation into the graft

 

Additional information:

 - Type A: ascending aorta

 - Type B: distal to left subclavian artery

 

 

WEEK 8:

CONGENITAL DIAPHRAGMATIC HERNIA:

Causes:

 - Failed fusion of septum transversum, pleuroperitoneal folds, dorsal mesentery of the oesophagus and lateral body / thoracic wall

 

Symptoms:

 - Signs of respiratory distress on left side of chest (70 breaths pm)

 - Not feeding very well

 - Concave abdomen

 - Cyanotic extremities

 - High heart rate

 - Decreased breath sounds of left side of the chest

 

Problems:

 - Pulmonary hypoplasia

 - Development of pulmonary hypertension

 - Cardiac dysfunction

 - High mortality (perinatal mortality as high as 80%)

 

Tests:

 - Radiograph - bowel loops within the left hemithorax

 

Management:

 - Immediate: oxygen and support

 - Surgery: repaired using prosthetic material

 

Additional information:

 - Two common types: Bochdalek hernia (more common on the left, posterolateral, large and associated with poorer outcome + Morgagni hernia (less common, anterior, presents later)

 - Most commonly caused by failure of one or both pleuroperitoneal membranes to separate the thorax (Bochdalek)

 - Can have some associated anomolies

 

TRACHEOOESOPHAGEAL FISTULA:

Causes:

 - Unsuccessful fusion of lung bud and foregut

 

Symptoms:

 - Increased oral secretions

 - Early signs of respiratory distress (tachypnoea)

 - Unsuccessful attempts at feeding in first few hours

 - Slight tachycardia

 

Problems:

 - Aspiration pneumonia

 - GORD with acid leaking into oesophagus

 - Asthma-like symptoms

 - Recurrent chest infections

 

Tests:

 - Radiograph

 - Contrast study using fluoroscopy (shows type of tracheo-oesophageal fistula)

 

Management:

 - Immediate: respiratory support

 - Surgical: closing off abnormal connection and joining upper and lower parts of the oesophagus

 

Additional information:

 - Often associated with other conditions e.g. ASD, VSD

 

ATRIAL SEPTAL DEFECT:

Symptoms:

 - Persistent cough

 - Auscultation of the heart reveals systolic murmur (aortic or pulmonary valve stenosis, mitral or tricuspid regurgitation or congenital septal defect

 

Problems:

 - Overload of pulmonary system eventually leads to damage of the pulmonary vasculature and pulmonary hypertension develops

 - Eventually right sided pressure will exceed left, causing some deoxygenated blood to pass through defect to left atrium, causing cyanosis (acyanotic -> cyanotic conditions)

 - Heart failure will ensue

 

Tests:

 - Auscultation test

 - Radiograph, ECG, echocardiogram, cardiac MRI (can see ASD)

 

Management:

 - Most small defects will close in the first year of life

 - Options include: percutaneous catheter closure or surgical intervention

 

PATENT DUCTUS ARTERIOSUS:

Causes:

 - Failure of ductus arteriosus to obliterate after birth (should close due to decrease in maternal prostaglandins and release of bradykinin from lungs)

 

Symptoms:

 - Acyanotic

 - Slight heart murmur

 - Mainly asymptomatic

 

Problems:

 - Heart failure, pulmonary hypertension or endarteritis by 40, 2/3 die by age 60

 

TETRALOGY OF FALLOT:

Causes:

 - Pulmonary stenosis

 - Right ventricular hypertrophy

 - Ventricular septal defect

 - Overiding aorta with right sided aortic arch

 - Caused by failure to form spiral septum (neural crest cells)

 

Symptoms:

 - Cyanosis (due to right-to-left shunting)

 

ABDOMEN:

WEEK 9:

INGUINAL HERNIA:

Symptoms:

 - Colicky abdominal pain

 - Vomiting

 - Constipation

 - Abdominal distension

 - Tender mass in the groin

 

Problems:

 - Risk of strangulation followed by ischemia and tissue death

 

Tests:

 - Radiograph + CT

 - Ask patient to cough/Valsalva → feel for impulse.

 - Reduce the hernia, then occlude deep inguinal ring with finger:

 - Indirect: Hernia reappears only after releasing pressure (blocked at deep ring).

 - Direct: Hernia reappears immediately (bypasses deep ring).

 

 

Management: - Immediate decompression and IV fluids + pain relief

 - In irreducible hernia, surgery is most likely required

 - If bowel becomes strangulated it must be resected and an anastomosis formed

 

Additional information:

 - Could be small bowel obstruction secondary to adhesions (history of previous surgery), colorectal tumour, diverticular mass with obstruction, volvulus or femoral hernia

 - Indirect inguinal hernia: pass through inguinal canal and both inguinal rings: lateral to IEA (weakness in processus vaginalis during testicular descent)

 - Direct inguinal hernias: pass through 'Hasselbach's triangle' so not through canal, do not enter deep ring, may pass through superficial ring arising medial to IEA (more common in older people due to weakened conjoint tendon)

 - Femoral hernia: through the femoral canal below the inguinal ligament

 

APPENDICITIS:

Symptoms:

 - Lower right abdominal pain

 - Pain began in the umbilical region before moving

 - Fever

 - Tachycardia

 

Problems:
 - Peritonitis

 

Tests:

 - Routine blood test, especially full blood count (white cells) and inflammatory markers

 - Ultrasound, CT

 

Management:

  1. Immediate: resuscitation, antibiotic and pain relief

  2. Non-surgical: in 30% of cases where appendix has been perforated, the patient can be treated with just antiobitics and drainage of peri-appendiceal abcesses

  3. Surgical: appendectomy - open or laparoscopically; done using Gridiron incision if open

 

MECKEL'S DIVERTICULITIS:

Symptoms:

 - Umbilical pain moving to right iliac fossa region

 

Tests:

 - Laparoscopy (pus in abdominal cavity)

 - Endoscopy

 - Imaging

 

Management:

 - Immediate: resuscitation, IV fluids

 - Laparoscopic or open diverticulectomy if needed

 

Additional information:

 - 2% affected, 2 inches long, 2 feet from ileocaecal valve

 - May contain gastric, pancreatic, liver carcinoid or lymph tissue

 - May also be vitelline cyst or fistula

 

COLORECTAL CARCINOMA:

Symptoms:

 - Pale

 - Weight loss

 - Palpable mass in the left iliac fossa

 

Problems:

 - Large bowel obstruction (surgical emergency)

 

Tests:

 - Examination of the liver (hepatomegaly secondary to metastases)

 - Digital rectal exam (any evidence of rectal mass?)

 - Blood test

 - Rectal exam

 - Sigmoidoscopy + colonoscopy

 - Radiograph

 

Additional information:

 - Could be diverticular mass, gynecological mass

 - Colorectal carcinoma is third most commonly diagnosed carcinoma after lung and breast cancer

 

DIVERTICULAR DISEASE + DIVERTICULITIS:

Symptoms: (of diverticular disease)

 - Intermittent lower abdominal pain

 - Bloating (flatulence)

 - Altered bowel habits

 - Rectal bleeding (if erode into blood vessels)

 

Problems: (leads to diverticulitis)

 -Severe left iliac fossa pain

 - Fever

 - Nausea/vomiting

 - Constipation

 - Peritonitis

 

Additional information:

 - Common in Western countries with about half of those over 60 affected in Canada and US

 - Greater prevalence with a low-fibre diet typical of Western populations

 - Typically occur in sigmoid colon

 

SIGMOID VOLVULUS:

Symptoms:

 - Distended abdomen

 - Large bowel obstruction (may be intermittent if it twists and untwists

 

Problems:

 - May become necrotic if blood supply is hindered

 

Tests:

 - Radiograph (coffee bean sign)

 

Additional information:

 - Prone to volvulus as it is on relatively broad and log mesentery + can also happen in caecum

 

WEEK 10:

OMPHALOCELE:

Causes:

 - Return of bowels during their rotation can fail causing them to herniate through umbilical cord

 

Symptoms:

 - Mass protruding from anterior abdominal wall

 - Covered in membrane

 

Tests:

 - Fetal ultrasound can detect this before birth

 

Management:

  1. Immediate: cover intestines with membrane (e.g. plastic cling wrap) + IV fluids to counter evaporative losses

  2. Surgery:

 - Small: immediate surgical closure

 - Reduction and closure should be accomplished gradually

 

Additional information:

 - Often associated with poorer diagnosis because it is often associated with abnormalities e.g. cardiac, chromosomal, genitourinary

 

GASTROSCHISIS:

Causes:

 - The bowel herniates out after they have successfully returned to the abdomen

 - Herniation occurs lateral to the umbilicus most commonly on the right where the umbilical vein weakens the anterior abdominal wall

 

Symptoms:

 - Mass protruding from anterior abdominal wall

 - No peritoneal sac / amnion membrane coverings over the herniated viscera

 

Additional information:

 - Associated anomalies are uncommon, and survival rates are 90%

 - But as an isolated anamoly, the prognosis is worse because the herniated viscera have no peritoneal or amniotic covering and can be damaged by the exposure to amniotic fluid

 

UMBILICAL HERNIA:

Symptoms:

 - Mass protruding from the umbilicus

 - Covered by skin

 

Additional information:

 - Passing of pale stools and dark urine

 - Jaundice (yellow sclera) and yellowy skin

 

Tests:

 - Murphy's sign: patient exhales fully whilst you have your fingers placed under their right costal margin. Patient then inhales -> if pain is felt this is a positive Murphy's sign

 - Ultrasound, CT, endoscopy

 

Management:

 - Immediate: fluid resuscitation, antibiotics and analgesia

 - Surgical: consider cholecystectomy (laparoscopic or open)

 

Additional information:

 - If gallstones without cholecystitis: no inflammation, stones may occasionally block ducts temporarily causing biliary colic (but no infection of inflammation), normal Murphy's sign, no shoulder pain

 - Cholecystitis can occur without gallstones with bile stasis, infection or ischaemia

 

PORTAL HYPERTENSION:

Causes:

 - Prehepatic e.g. portal vein thrombosis

 - Prompt endovascular aneurysm repair or open surgery (distal colon still vascularised if graft blocks IMA because of marginal artery of Drummond)

 

Additional information:

 - Different types of AAA: suprarenal, pararenal, juxtarenal, infrarenal

 - Aneurysms involving the renal arteries are associated with increased morbidity

 - Pancreatitis and a perforated gastric ulcer can both present with back pain + both are life-threatening

WEEK 8:

PROSTATE CANCER:

Risk factors:

 - Family history of breast cancer

 - African American men experience highest rates of prostate cancer

 

Symptoms:

 - Urinary frequency

 - Nocturia (waking up to urinate)

 - Hesitancy

 - Poor stream

 - Back pain (suggests advanced disease)

 - Haematuria (suggests advanced disease)

 

Tests:

 - Microscopic haematuria can be detected

 - Rectal examination: enlarged prostate can be palpated anteriorly

 - MRI

 - Biopsy aided by ultrasound (rectum must be clear of faeces + antibiotics required to prevent rectal bacteria causing prostatitis

 

Management:

 - Prostatectomy potentially

 - Chemotherapy, immunotherapy or chemotherapy

 

Problems after treatment:

 - Risk of loss of erectile function through damage to cavernous nerves lying posterolateral to the prostate: carry parasympathetic innervation from S2-4 to facilitate penile erection

 

Additional information:

 - May be benign prostatic hypertrophy that has caused urinary symptoms

 - Prostate tumours often arise in the posterior/peripheral prostate gland more commonly than in anterior gland and central zone, thus no symptoms in the early stages

 - Prostate cancer frequently metastasises to the vertebrae via Batson's plexus (valveless)

 - Rectoprostatic (Denonvilliers') fascia separates the prostate and urinary bladder from the rectum and initially prevents posterior spread of prostate cancer

 

OVARIAN CANCER:

Risk factors:

 - Mutations in either breast cancer gene: BRCA1 or BRCA2

 

Symptoms:

 - Abdominal heaviness, shortness of breath, weight loss and early satiety (non-specific symptoms)

 - Pelvic pain

 - Fullness in the left iliac fossa

 - Nausea

 - Slight swelling of left side of scrotum

 - Acutely painful to touch

 - Right testicle feels a little higher than left side

 

Problems:

 - Occlusion of testicular venous return

 - Compromise of the arterial supply, resulting in ischaemia of the testis

 

Tests:

 - Ultrasound with doppler

 

VARICOCELE (left vs right):

Causes:

 - Dilatation of the pampiniform plexus of veins

 

Symptoms:

 - Dragging sensation in left scrotum and noticed a 'bag of worms'

 

Tests:

 - CT

 

Additional information:

 - 15% of the general male population affected

 - Left testis is affected much more commonly than the right - maybe due to shorter course of the right testicular vein and its oblique insertion into the IVC which is also at a lower pressure vs. left testicular vein has longer course and inserts into left renal vein at a right angle and the renal veins are at a higher pressure

 - Bilateral varicoceles are not uncommon

 - Secondary varicocele comes from increased pressure in the testicular veindue to compression e.g. extrinsic mass

 

LOWER LIMB:

WEEK 13:

SAPHENA VARIX:

Symptoms:

 - Bulge inferolateral to pubic tubercle

 - Bluish tinge

 

Tests:

 - Tap test: place one finger over the saphena varix at the saphenofemoral junction -> use your other hand to tap over the great saphenous vein lower down -> if a transmitted impulse is felt at the SFJ it suggests valve incompetence is present

 - Cough impulse test: place fingers gently over groin swelling -> ask patient to cough -> sudden outward impulse against fingers suggests saphena varix / inguinal hernia / femoral hernia

 

Management:

 - Conservative management with compression therapy may improve symptoms of chronic venous insufficiency

 - Surgery using ligation

 

DEVELOPMENTAL DYSPLASIA OF THE HIP:

Risk factors:

 - Premature birth

TRENDELENBERG GAIT:

Causes:

 - Loss of function of gluteus medius, tensor fascia lata and minimus e.g. due to superior gluteal nerve damage

 

Risk factors:

 - Hip replacement recently: lateral approach can damage the inferior division of the superior gluteal nerve which innervates gluteus medius and gluteus minimus

 

Symptoms:

 - 'Waddling' when he walks -> he leans over to the right side to be able to keep his balance and to swing his left leg forward

 

FOOT DROP:

Causes:

 - Common fibular nerve injury

 

Risk factors:

 - Hip replacement recently: posterior approach can damage sciatic nerve

 

Symptoms:

 - Bleeding, infection and nerve injury

 - Hospital acquired infection and DVT/PE

 - Poor mobility, chronic pain and dislocation

 

Management:

 - Hemi-arthroplasty (partial hip replacement)

 - Intertrochanteric fracture treated with plate and screw

 - Total hip replacement (e.g. osteoarthritis)

 

Problems after treatment:

 - Risk of dislocation following hip replacement is greater as capsule and supporting ligament must be disrupted to remove the femoral head

KNEE INJURY:

Causes:

 - ACL is damaged from hyperextension

 - PCL is damaged from hyperflexion

 - Lateral blow may rupture the MCL

 - Medial blow may rupture the LCL

 - Twisting is associated with ACL, PCL and meniscus tears

 - MCL often torn with medial meniscus

 - Lateral meniscus and LCL are separated by tendon of popliteus, so they don't get injured together

 

Symptoms:

 - Pain and swelling of the knee

 - Difficulty weight bearing

 

Tests:

 - Anterior drawer test: pull tibia forwards relative to femur with patient with flexed knee - excessive anterior movement suggests ACL damage

 - Posterior sag sign: if tibia sags beckwards relative to the femur in flexed knee - suggests PCL damage

 - Valgus stress for MCL, varus stress for LCL

 - MRI, CT, ultrasound

 

Management:

  1.  Immediate: ice, analgesia, ani-inflammatories, rest, elevation

  2. Medical: physio and rehabilitative therapy

 - Ultrasound, MRI

 

Management:

  1. Immediate: pain-relief, anti-inflammatories and ice pack

  2. Conservative/physical: ankle immobilisation in cast

  3. Operative: open surgery or percutaneous repair

 

Additional information:

 - Muscles that cross two joints are especially susceptible to injury e.g. gastrocnemius

- wasting of the quads – especially vastus medialis. These fibres waste (atrophy) quickly after bed rest or prolonged effusion->unsteady feeling with lateral pull

- being female (wider pelvis and larger Q angle which increases the lateral component of the quadricep vector.

- previous dislocation and tear of the medial patella retinaculum

 

Symptoms:

 - Patella is laterally displaced

 

Tests:

 - Radiograph

 

Management:

 - Damage to anterior talofibular and lateral calcaneofibular ligaments

 

Tests:

 - Assess pulses: posterior tibial pulse, anterior tibial pulse, dorsalis pedis pulse

 - Assess sensory function: first dorsal web space is supplied by the deep branch of the common fibular nerve + rest of dorsum is supplied by the superficial branch of the common fibular nerve

 

Additional information:

 - Eversion injuries can damage deltoid ligament

 - Different types of inversion injuries of the ankle (e.g. tear of calcaneofibular ligament OR lateral malleolus fracture with intact ligament OR lateral+medial malleolus tear with intact ligament
