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 |

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.
What is the most likely diagnosis? |
Migraine |

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) |

A 3-year-old girl is brought in by her mother. Her mother reports that she has been eating less and refusing food for the past few weeks. 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 |

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. |

A 32 year old pregnant woman presents to the GP with jaundice, and itchy skin for the past 2 weeks. She claims that is a lot worse during this pregnancy compared to her last one. History reveals that she is currently 30 weeks pregnant with no complications up until presentation. On examination the only notable findings are mild jaundice seen in the sclerae, as well as excoriations around the umbilicus and flanks. 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

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 |

|
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

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 |

|
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 |
neovascularisation, exudative |

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. |

Gliclazide |
|
COMMON AE of sulfonylureas |
hypoglycemic episodes WEIGHT GAIN |
|
Sulfonylureas are oral hypoglycaemic drugs used in the management of type 2 diabetes mellitus. They work by |
increasing pancreatic insulin secretion and hence are only effective if functional B-cells are present. On a molecular level they bind to an ATP-dependent K+(KATP) channel on the cell membrane of pancreatic beta cells. |

A 39-year-old man comes for review. Six months ago he was started on paroxetine for depression. Around five days ago he stopped taking the medication as he felt that it was having no benefit. His only past medical history of note is asthma. For the past two days he has experienced increased anxiety, sweating, headache and the feeling of a needle like sensation in his head. During the consultation he is pacing around the room. What is the most explanation for his symptoms? |
Selective serotonin reuptake inhibitor`discontinuation syndrome |
|
paroxetine is |
an SSRI |
|
Paroxetine has a higher incidence of discontinuation symptoms than other |
SSRIs |
|
1st line tx for depression |
SSRI = citalopram or fluoxetine fluoxetine 1st line for kids/teens sertraline useful post MI |
