Addison's disease in a patient with hypothyroidism: autoimmune polyglandular syndrome type 2.

A 57-year-old Caucasian woman with known autoimmune hypothyroidism diagnosed in 2006 presented to hospital with flu-like symptoms and circulatory collapse. She reported weight loss and gradual increase in her skin pigmentation over a 1-year period. Aggressive fluid resuscitation was instituted. Hormonal tests showed primary adrenal insufficiency. Appropriate steroid replacement was started with rapid clinical response. Subsequent antibody tests confirmed the diagnosis of autoimmune polyglandular type 2 (Schmidt's) syndrome. The adrenal crisis had been precipitated by influenza virus type B infection.

Dual life-threatening pathologies presenting simultaneously.

A 70-year-old male presented to hospital with both anterior ST elevation myocardial infarction and spontaneous oesophageal rupture (Boerhaave's syndrome). He underwent primary angioplasty and stenting for a lesion of the left anterior descending in addition to cardiothoracic surgery for the oesophageal rupture. This combination of pathologies is a rare entity and often difficult to diagnose. To date, only a few cases have been reported.

Effect of remote ischaemic preconditioning on myocardial injury in patients undergoing coronary artery bypass graft surgery: a randomised controlled trial.

BACKGROUND: Whether remote ischaemic preconditioning, an intervention in which brief ischaemia of one tissue or organ protects remote organs from a sustained episode of ischaemia, is beneficial for patients undergoing coronary artery bypass graft surgery is unknown. We did a single-blinded randomised controlled study to establish whether remote ischaemic preconditioning reduces myocardial injury in these patients. METHODS: 57 adult patients undergoing elective coronary artery bypass graft surgery were randomly assigned to either a remote ischaemic preconditioning group (n=27) or to a control group (n=30) after induction of anaesthesia. Remote ischaemic preconditioning consisted of three 5-min cycles of right upper limb ischaemia, induced by an automated cuff-inflator placed on the upper arm and inflated to 200 mm Hg, with an intervening 5 min of reperfusion during which the cuff was deflated. Serum troponin-T concentration was measured before surgery and at 6, 12, 24, 48, and 72 h after surgery. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00397163. FINDINGS: Remote ischaemic preconditioning significantly reduced overall serum troponin-T release at 6, 12, 24, and 48 h after surgery. The total area under the curve was reduced by 43%, from 36.12 microg/L (SD 26.08) in the control group to 20.58 microg/L (9.58) in the remote ischaemic preconditioning group (mean difference 15.55 [SD 5.32]; 95% CI 4.88-26.21; p=0.005). INTERPRETATION: We have shown that adult patients undergoing elective coronary artery bypass graft surgery at a single tertiary centre could benefit from remote ischaemic preconditioning, using transient upper limb ischaemia.
