INV for SLE

Immunology


99% are ANA positive


20% are rheumatoid factor positive


anti-dsDNA: highly specific (> 99%), but less sensitive (70%)


anti-Smith: most specific (> 99%), sensitivity (30%)


also: anti-U1 RNP, SS-A (anti-Ro) and SS-B (anti-La)



Monitoring


ESR


C4 complement levels


anti-dsDNA (nb not in all pxs)

STEMI def

new ST elevation at the J-point in two contiguous leads with the cut-off points: >=0.2 mV in men or >= 0.15 mV in women in leads V2-V3 and/or >= 0.1 mV in other leads

Acute MI

hyperacute T waves are often the first sign of MI but often only persists for a few minutes


ST elevation may then develop


the T waves typically become inverted within the first 24 hours. The inversion of the T waves can last for days to months


pathological Q waves develop after several hours to days. This change usually persists indefinitely

Chronic obstructive pulmonary disease requires spirometry to confirm the diagnosis but this chest x-ray is highly suggestive.



Fxs include

hyperinflation


flattened hemidiaphragms


hyperlucent lung fields

The severity of COPD is categorised using the FEV1*:


Post-bronchodilator FEV1/FVC FEV1 (of predicted) Severity



< 0.7 > 80% Stage 1 - Mild**



< 0.7 50-79% Stage 2 - Moderate



< 0.7 30-49% Stage 3 - Severe



< 0.7 < 30% Stage 4 - Very severe

< 0.7 50-79% Stage 2 - Moderate



< 0.7 30-49% Stage 3 - Severe



< 0.7 < 30% Stage 4 - Very severe

The following investigations are recommended in patients with suspected COPD:

post-bronchodilator spirometry to demonstrate airflow obstruction: FEV1/FVC ratio less than 70%


chest x-ray: hyperinflation, bullae, flat hemidiaphragm. Also important to exclude lung cancer


full blood count: exclude secondary polycythaemia

Refer to specialist

Leukotriene receptor antagonists

e.g. Montelukast, zafirlukast


have both anti-inflammatory and bronchodilatory properties


should be used when patients are poorly controlled on high-dose inhaled corticosteroids and a long-acting b2-agonist


particularly useful in aspirin-induced asthma


associated with the development of Churg-Strauss syndrome

Long acting B2-agonists acts as

bronchodilators but also inhibit mediator release from mast cells.




Recent meta-analysis showed adding salmeterol improved symptoms compared to doubling the inhaled steroid dose

A 25-year-old man presents for review. For the past year he has been experiencing headaches. These are now occurring around 5-6 times per month and typically 'last all day' when they occur. They are not associated with any form of aura. A typical headache is described as a severe throbbing on both sides of his head associated with nausea and lethargy. When he gets such a headache he typically goes to bed so he can 'sleep it off'. Before going to bed he typically takes one of his father's diclofenac tablets which seem to help.



Neurological examination is unremarkable.

In a px with aki who is hypotensive n needs IV fluids, why wouldnt you give hartmanns solution?

Hartmann's solution contains potassium, therefore in the setting of an acute kidney injury, it might be more appropriate to give 0.9% saline, which does not contain any potassium, since hyperkalaemia is a concern in AKI.

What does the power of the study equte to?

Power = 1 - the probability of a type II error

Power explanation

A null hypothesis (H0) states that two treatments are equally effective (and is hence negatively phrased). A significance test uses the sample data to assess how likely the null hypothesis is to be correct.



For example:


'there is no difference in the prevalence of colorectal cancer in patients taking low-dose aspirin compared to those who are not'



The alternative hypothesis (H1) is the opposite of the null hypothesis, i.e. There is a difference between the two treatments



The p value is the probability of obtaining a result by chance at least as extreme as the one that was actually observed, assuming that the null hypothesis is true. It is therefore equal to the chance of making a type I error (see below).



Two types of errors may occur when testing the null hypothesis


type I: the null hypothesis is rejected when it is true - i.e. Showing a difference between two groups when it doesn't exist, a false positive. This is determined against a preset significance level (termed alpha). As the significance level is determined in advance the chance of making a type I error is not affected by sample size. It is however increased if the number of end-points are increased. For example if a study has 20 end-points it is likely one of these will be reached, just by chance.


type II: the null hypothesis is accepted when it is false - i.e. Failing to spot a difference when one really exists, a false negative. The probability of making a type II error is termed beta. It is determined by both sample size and alpha



The power of a study is the probability of (correctly) rejecting the null hypothesis when it is false, i.e. the probability of detecting a statistically significant difference


power = 1 - the probability of a type II error


power can be increased by increasing the sample size




Study accepts H0 Study rejects H0


Reality H0 Type 1 error (alpha)


Reality H1 Type 2 error (beta) Power (1 - beta)

Despite this her mother has noticed that her abdomen is distended and she has developed a 'beer belly'. For the past year she has opened her bowels around once every other day, passing a stool of 'normal' consistency. There are no urinary symptoms. On examination she is on the 50th centile for height and weight. Her abdomen is soft but slightly distended and a non-tender ballotable mass can be felt on the left side. Her mother has tried lactulose but there has no significant improvement. What is the most appropriate next step in management?

A 27 year old woman is becoming exhausted during labour, and there are new signs on the foetal monitor to suggest foetal distress The midwife elects to attempt a forceps assisted delivery.



Which of the following is more a more likely potential complication associated with this procedure?

Facial nerve palsy

indication for assisted delivery. This may be performed using forceps or a ventouse device. During a forceps delivery, the forceps are applied around the face of the foetus and a force is applied by the user in order to aid delivery. As there is compression to the sides of the face, the facial nerve is at risk of being damaged resulting in facial nerve palsy. This may be temporary or permanent. The other optional answers in the question (other than Erb's palsy) are complications that are more associated with ventouse assisted deliveries. Erb's palsy can be a complication of shoulder dystocia.

A 26 year old pregnant woman is found to be blood group Rhesus (D) negative at booking. Which of the following is an indication for administration of anti-D?

Amniocentesis




In rhesus negative mothers, mixing of maternal and fetal blood may precipitate isoimmunisation, resulting in immune hydrops for the fetus. Amniocentesis, external cephalic version, blunt abdominal trauma and caesarean section are some of the 'sensitising events' which may do this. In case of rhesus sensitisation, anti-D can be given to the mother to remove any circulating antibodies to fetal red blood cells.

A basic understanding of the pathophysiology is essential to understand the management of Rhesus negative pregnancies

along with the ABO system the Rhesus system is the most important antigen found on red blood cells. The D antigen is the most important antigen of the rhesus system


around 15% of mothers are rhesus negative (Rh -ve)


if a Rh -ve mother delivers a Rh +ve child a leak of fetal red blood cells may occur


this causes anti-D IgG antibodies to form in mother


in later pregnancies these can cross placenta and cause haemolysis in fetus


this can also occur in the first pregnancy due to leaks

Ectopic pregnancy



A typical history is a female with a history of 6-8 weeks amenorrhoea who presents with lower abdominal pain and later develops vaginal bleeding

lower abdominal pain: typically the first symptom. Pain is usually constant and may be unilateral. Due to tubal spasm


vaginal bleeding: usually less than a normal period, may be dark brown in colour


history of recent amenorrhoea: typically 6-8 weeks from start of last period; if longer (e.g. 10 wks) this suggest another causes e.g. inevitable abortion


peritoneal bleeding can cause shoulder tip pain and pain on defecation / urination

A 60 year old woman presents to the Emergency Department with a three week history of breathlessness and a dry cough. She does not smoke but admits drinks 20 units of alcohol per week. There is a target rash present on both her lower limbs. Her chest x-ray shows reticulo-nodular shadowing of the right lung. A diagnosis of bacterial pneumonia is made, what is the most likely organism causing her symptoms.

Mycoplasma pneumoniae




The dry cough, erythema multiforme (symmetrical target shaped rash with a central blister) and the radiological findings point to a diagnosis of Mycoplasma.




nb Klebsiella occurs in alcoholics, and although the woman drinks more than her allowance (for women this is 14 units a week) it is not at the level where it would predispose her to Klebsiella. Furthermore, it typically causes a cavitating pneumonia of the upper lobes.

Although pneumococcal pneumonia is the most common pneumonia in the community, you would expect lobar consolidation on x-ray as well as a productive, rather than dry, cough.

She denies any tenderness in her abdomen during the examination. Blood tests show the following:



ALT 206 U/L


AST 159 U/L


ALP 796 umol/l


GGT 397 U/L


Bilirubin (direct) 56 umol/L


Bile salts 34 umol/L



Bile salts reference range 0 - 14 umol/L



What is the most likely diagnosis?

Obstetric cholestasis also known as intrahepatic cholestasis of pregnancy

Obstetric cholestasis also known as intrahepatic cholestasis of pregnancy description

is a condition caused by the impaired flow of bile. This in turn causes a build up of bile salts which can then deposit in the skin (causing pruritus) as well as the placenta. It is thought that the aetiology of this condition is a combination of hormonal, genetic and environmental factors.



Although the pruritic symptoms can be distressing for the mother, the build of of bile salts can also be detrimental to foetal wellbeing. The combination of the immature foetal liver's ability to cope with breaking down the excessive bile salt levels as well as the vasoconstricting effect of bile salts on human placental chorionic veins, has been theorised to be the cause of sudden asphyxial events in the foetus leading to anoxia and death

pH 7.12, pCO2 3.1kPa, pO2 11.8kPa, HCO3- 6.2mmol/L. Calculated anion gap is 26mmol/L.

Metabolic acidosis

Patients who have sepsis often have a raised serum lactate due to the hypoperfusion of their peripheries. This gives them a metabolic acidosis with a raised anion gap.



In patients with a metabolic acidosis, it can be helpful to calculate the anion gap in order to identify the cause of the metabolic acidosis. This is calculated as the difference between plasma cations (Na+ and K+) and anions (Cl- and HCO3-). The normal range is 10-18mmol/L.



If the anion gap is raised, this suggests that there is increased production, or reduced excretion, of fixed/ organic acids e.g.


Lactic acid (sepsis, tissue ischaemia)


Urate (renal failure)


Ketones (diabetic ketoacidosis)


Drugs/ toxins (salicylates, methanol, ethylene glycol)



If there is a metabolic acidosis with a normal anion gap, then this is either due to loss of bicarbonate, or accumulation of H+ ions. Causes include:


Renal tubular acidosis


Diarrhoea


Addison's disease


Pancreatic fistula

Metabolic acidosis

Metabolic acidosis is commonly classified according to the anion gap. This can be calculated by: (Na+ + K+) - (Cl- + HCO-3). If a question supplies the chloride level then this is often a clue that the anion gap should be calculated. The normal range = 10-18 mmol/L



Normal anion gap ( = hyperchloraemic metabolic acidosis)


gastrointestinal bicarbonate loss: diarrhoea, ureterosigmoidostomy, fistula


renal tubular acidosis


drugs: e.g. acetazolamide


ammonium chloride injection


Addison's disease



Raised anion gap


lactate: shock, hypoxia


ketones: diabetic ketoacidosis, alcohol


urate: renal failure


acid poisoning: salicylates, methanol



Metabolic acidosis secondary to high lactate levels may be subdivided into two types:


lactic acidosis type A: shock, hypoxia, burns


lactic acidosis type B: metformin

A 22 year-old woman and her male partner present to their GP as they been unsuccessfully trying to conceive for 4 months. Her periods have been regular and there is no obvious cause in her history. What is the most appropriate next step in her management?

Address how the couple are having sexual intercourse and reassure the patient

A healthy couple can expect to take up to one year to conceive. Investigations are therefore usually performed after

one year of regular attempts to conceive.




It may however be prudent to address any mechanical reasons that are preventing the couple from conceiving, hence the sexual intercourse history.

Infertility affects around 1 in 7 couples. Around 84% of couples who have regular sex will conceive within 1 year, and 92% within 2 years

Which one of the following defines the standard error of the mean?

Standard deviation / square root (number of patients)

How is the confidence interval calculated?

The standard error of the mean (SEM) is a measure of the spread expected for the mean of the observations - i.e. how 'accurate' the calculated sample mean is from the true population mean




Key point


SEM = SD / square root (n)


where SD = standard deviation and n = sample size


therefore the SEM gets smaller as the sample size (n) increases




A 95% confidence interval:


lower limit = mean - (1.96 * SEM)


upper limit = mean + (1.96 * SEM)




nb if a small sample size is used (e.g. n < 100) then it is important to use a 'Student's T critical value' look-up table to replace 1.96 with a different valueif a different confidence level is required, e.g. 90% then 1.96 is replaced by a different value. For 90% this would 1.645

Confidence interval def

a range of values within which the true effect of intervention is likely to lie




nb a formal definition may be: a range of values for a variable of interest constructed so that this range has a specified probability of including the true value of the variable. The specified probability is called the confidence level, and the end points of the confidence interval are called the confidence limits




The likelihood of the true effect lying within the confidence interval is determined by the confidence level. For example a confidence interval at the 95% confidence level means that the confidence interval should contain the true effect of intervention 95% of the time

A 65-year-old man with a 16 year history of type 2 diabetes mellitus presents complaining of poor eye sight and blurred vision. Visual acuity measured using a Snellen chart is reduced to 6/12 in the right eye and 6/18 in the left eye. Fundoscopy reveals a number of yellow deposits in the left eye consistent with drusen formation. Similar changes but to a lesser extent are seen in the right eye. What is the most likely diagnosis?

Dry age-related macular degeneration

Drusen = Dry macular degeneration

Fundoscopy showing yellow deposits in the eye = consistent with drusen formation





Age related macular degeneration is a common cause of

blindness

Age related macular degeneration

Degeneration of the central retina (macula) is the key feature with changes usually bilateral

Traditionally two forms of macular degeneration are seen:

dry and wet macular degen

dry (geographic atrophy) macular degeneration:

characterised by drusen - yellow round spots in Bruch's membrane

wet (exudative, neovascular) macular degeneration:

characterised by choroidal neovascularisation.




Leakage of serous fluid and blood can subsequently result in a rapid loss of vision.




Carries worst prognosis

Recently there has been a move to a more updated classification:

early age related macular degeneration




late age related macular degeneration

early age related macular degeneration (non-exudative, age related maculopathy):

drusen and alterations to the retinal pigment epithelium (RPE)

late age related macular degeneration

You are called to see a lady who has delivered her second child 2 hours ago. The baby was term, weighed 4.1kg, and was healthy. The labour was natural, lasted 6 hours, and she chose to have a physiological third stage. The nurse tells you she thinks she has lost approximately 800ml of blood, but her observations are stable and the bleeding appears to be slowing. What is the most common cause of her blood loss?

Uterine atony

Primary postpartum haemorrhage is defined as

the loss of 500ml or more from the genital tract within 24 hours of the birth of a baby.




This can be further defined as




- minor haemorrhage (500-1000ml) or




- major haemorrhage (>1000ml), and causes 6 deaths/million deliveries.
