Read week

19

Hi everyone!

How good does it feel to be safe at home?! Look around your room now for a minute and be give thanks for safety, a comfortable seat, a desk, opportunity to study and the ability to earn income.

This week is about travel medicine, infectious diseases and refugee medicine.

Travel is fantastic and should be encouraged. However, international travel carries with it inherent risks. It is important for each registrar to know how to do detailed travel counselling to include information about travel vaccination schedules, dealing with traveller’s diarrhoea, risk reduction strategies, and malaria prophylaxis.  Travel insurance should be emphasised.

It’s not uncommon for young men and women to attend the clinic for something quite benign like a contraception pill script or a common cold. Given the propensity for this population group for having sexually transmitted infections (STIs) it is very important to take a brief history around this. Identify their risk of different infections and test appropriately. While in the past a urine PCR was done on first catch urine, it is now recommended to do more opportunistic checks with a random urine. Don’t be afraid to treat for chlamydia/gonorrhoea if suspicious of infection before investigations return. 

Hepatitis C and HIV positive patients need to be found in our community – and this needs to be done by appropriate screening for risk of blood virus transmission. Ask the patient about their sexual history (who sticks what where), use of IV drugs, history of incarceration etc. These conditions are now treatable and are not fatal as they once were. We need to destigmatise these conditions to encourage appropriate testing.

Look after yourself, and be grateful every day for where you are in the world!
