People often remark to me, 'Wah working in emergency department must be very exciting! I bet you gets to see lots of gory injuries and things people 'accidentally' stick up their various orifices!'

Don't worry, you won't be seeing any of those. :)

What you WILL see, however, are interesting photos, ECGs, Xrays etc. which serve to remind us of the vast variety of cases that may come our way, and some of the learning points behind them.

Enjoy. :)

Case 10

20 year old Indian male construction foreign-talent brought into the A&E in semi-conscious state.

His worried colleagues claim that he has been lethargic for a few weeks, with episodes of abdominal pain and seems to have lost weight. They initially blamed it on him losing money at RWS.

BP 100/60, Temp 37.6
Groaning away
abdo : diffusely tender

UC9 : negative for WBC, blood, glucose or protein
Na 128, K 6.5, Urea 14, Bicarb 12.8 (all in mmol/l)

What is your diagnosis?

Answer : Addisonian crisis
  • acute and life-threatening condition due to adrenal (cortisol and aldosterone) deficiency.
  • most common cause : adrenal suppression due to long-term corticosteroid use with subsequent abrupt withdrawal or sudden exposure to increased stress (e.g. illness, injury, surgery etc).
  • other causes : autoimmune adrenalitis (in developed countries), infections e.g. TB (developing countries), metastasis, heparin therapy
Clinical features (usually non-specific)
  • Weakness, nausea, vomiting
  • abdominal pain
  • weight loss, loss of appetite
  • increased pigmentation of skin and mucous membrane
  • Inx : hyponatremia, hyperkalemia, metabolic acidosis, hypoglycemia, pre-renal azotemia
  • Definitive tests such as the short and long Synacthen tests are usually not done at the level of the ED
Management
  • High index of suspicion
  • fluid resuscitation (dextrose saline preferable)
  • IV Hydrocortisone 100 mg bolus (Hydrocort messes up the synacthen test so may consider using IV Dexamethasone 4 mg IV instead)
  • Search for precipitating cause (e.g. sepsis, trauma, acute coronary syndrome etc)
  • Admit to HD/ ICU under Endocrinologist for close monitoring and management
