50/f w haematemesis

I vomited blood last night after waking up around 2am feeling nauseous. It then settled for awhile and I had a second vomit about half an hour later. This time there were sesame seed sized black bits in my vomit. 

Focused Hx: Did not wretch before vomiting. Denies abdo pain. Denies urinary (freq, noct, dys) sx, constipation/diarrhoea, Otherwise well nil meds nil medical hx.

O/E: Dry membranes, BP 100/65, HR 75. Afebrile. Abdo tender on deep palp of LLQ and L renal angle otherwise SNT bowel sounds present, no organomegaly. FWT trace blood nil leuks nil nitrates.

Ix: FBE U&E CRP LFT Amylase/Lipase normal. AXR (erect/supine) mild fecal loading otherwise n.

She looks a bit dry so you start her on 4/24 1000ml N. Along with this 40mg Esomeprazole is given as well.

The investigations came back and you are just about to discharge the patient with an outpatient gastroscopy referral when the nurse calls you out:

ATSP: pt has a BP of 90/59

You quickly examine the patient. Her ex findings are the same as before. GCS 15 alert and communicative. The bag is nearlly empty so she has been transfused roughly 800ml in the past three hours.

What would you do next?

20/f w recurrent tonsillitis

It started with a sore throat, fever and chills. My GP started me on oral abx but I found it increasingly difficult to swallow. I was admitted for a day in hospital for iv abx and steroids to bring down the swelling. It's getting better now. Thank goodness it's my first time I've had to be admitted to hospital for tonsillitis.

Further Hx: Pt has completed 7/7 2g Cephazolin iv. Noted allergies to cetirimide and penicillin (rash).

O/E: Mildly sore on R side of throat. A bit of pus is visible on the posterior aspect of the tonsils. The tonsils are enlarged bilaterally and symmetrically but not erythematous.

Plan: Discharge the patient home on oral abx.


What antibiotics would be suitable? More importantly, what's missing from the plan?

45/f waking up at night feeling SOB, 'choking'

I've been waking up feeling like im choking for the past 2/52. Had a cold the week prior to that. It's pretty bad, I wake up and cough and cough and cough until I feel nauseous. I have vomited a few times because of that.

Further Hx: Clear sputum. Denies chills/rigors/wheeze/sweats. Sleeps on 3 pillows. Denies increasing SOBOE. No travel hx. Mild LOW but assoc dieting. Otherwise well no medical history no meds.

Ix: FBE/U&E/CRP normal. CXR clear.

O/E: Stable afebrile. Lying comfortably. Chest clear no added sounds. Pt feels "well" otherwise. Throat looks clear.

What examination is missing? Likely dx?

80/m w painful unilateral knee

Been having increasing pain in my L knee all night until it became unbearable. Can no longer weight bear on that side and it's really sore to touch here (pointing at medial aspect of knee). It came on all of a sudden. Hadnt bumped it or anything.

Hx: Gout on Allopurinol, IHD, CRF (eGFR in the 20s), OA w reduced joint space in both knees.

O/E: (L knee) No obvious swelling, erythema, or deformity noted. Has gouty tophi on hands. Otherwise stable,  afebrile.

Ix: WCC 13 (10) CRP 2.1 Urate 42 (n<20), ESR 52 (n<20), eGFR 18, Urea 18, Cr 292.

Does this patient need a joint MRI and aspirate?

80yo w sudden pain in R leg

It was like a sharp pain from my left knee downwards. My whole lower leg just hurt and was very sore to touch. I also noticed it was alot cooler than the other leg. It got worse over minutes and became really unbearable which was why i called the ambulance.

Hx
Longstanding AF but not on warfarin due to allergy (pruritic rash).
Known peripheral vascular disease w bilateral femoral grafts 2 years ago.

O/E
pain resolving spontaneously, but it is noted that pt had 5mg of morphine 2/24 prior.
pedal pulses strong and equal bilat.
both feet are equally warm.
both calves are symmetrical in size and non-tender.

Progress:
- A vascular registrar was consulted and an urgent doppler ultrasound was ordered which showed monophasic flow from the mid femur onwards.
- Is there need for an urgent embolectomy/angioplasty?

Welcome To Bite Sized Medicine

Using this site is simple. Visualize the scenario, imagine yourself being responsible for making a decision, and learn tangentially from the real-life case.

Medicine can be really overwhelming sometimes. Thankfully, it makes sense (well, mostly) and alot of things can be learnt relatively easily. IMO, the limiting factor in learning medicine (or CME) is time. It takes time to integrate mental processes into working memory. Put simply, practical knowledge takes time to absorb. Books tend to overwhelm/inundate the reader with too many facts and verbal overshadowing.

This blog takes a different approach to learning medicine. It features the following:

1. Emphasis on keeping it real. Only real life scenarios are used.
2. Small learning points in each scenario that could be easily integrated into your working memory

Difficulty is measured NOT by how difficult a learning point is to understand. It is measured by how intuitive the post will be to the reader. Many third year medical students could probably narrate ECG changes seen during an acute myocardial infarct; but few would be able to integrate the principles of managing an infarct that easily.

• Level 1; 3rd year medical students will find it easy to integrate these concepts. Also the basic stuff you just need to memorize and take to heart.
• Level 2; Bog standard medical practice points. Most doctors should easily visualize and understand this.
• Level 3; Judgement calls made by senior medical officers.
• Level 4; Judgment calls made by consultants. 

Specialty labels are given based on what specialists were consulted in order to make judgment calls. If a particular case required a call to the renal physician, it will be labelled as a Nephrology case. If it also required an O&G consult then it also be labelled as such (r Nephrology, r OnG). I've decided to label things this way to prevent confusion as a simple pneumonia would qualify under Pneumology and Infectious Diseases. Cases that did not receive any specialty consult will be labelled under General Medicine unless they are suitably labelled as Emergencies.
