A 62-year-old woman with low back pain was eventually diagnosed with vertebral osteomyelitis after multiple visits to emergency, primary and specialty care. The absence of traditional 'red flags' from her history and examination serves as an important reminder that their absence does not necessarily reflect benign pathology.

A 29-year-old patient attended our institution for recurrent strokes related to a giant partially thrombosed M1 aneurysm. Superficial temporal artery-middle cerebral artery (STA-MCA) bypass and subsequent occlusion of both the aneurysm and the dysplastic M1 segment were planned. However, owing to the shortness of the non-dysplastic segment of M1 and the risk of occlusion of the lenticulostriate arteries, the use of a double-lumen balloon was considered for coiling and subsequent injection of Onyx. ⋯ Endovascular occlusion of both the aneurysm and the parent artery was subsequently performed by means of coils and Onyx-34 that was injected via the Ascent balloon under balloon inflation. No complications were recorded and no stroke was observed on control MRI. The injection of Onyx-34 through a double-lumen balloon under balloon inflation is a quick and safe technique for precise occlusion of a parent artery.

Case Reports
Inhaled β-agonist therapy and respiratory muscle fatigue as under-recognised causes of lactic acidosis.
A 49-year-old man with chronic obstructive pulmonary disease (COPD) presented with significant tachypnoea, fevers, productive cough and increased work of breathing for the previous 4 days. Laboratory data showed elevated lactate of 3.2 mEq/L. Continuous inhaled ipratropium and albuterol nebuliser treatments were administered. ⋯ No infectious source was found and the lactic acidosis cleared as the patient improved. The lactic acidosis was determined to be secondary to respiratory muscle fatigue and inhaled β-agonist therapy, two under-recognised causes of lactic acidosis in patients presenting with respiratory distress. Lactic acidosis is commonly used as a clinical marker for sepsis and shock, but in the absence of tissue hypoperfusion and severe hypoxia, alternative aetiologies for elevated levels should be sought to avoid unnecessary and potentially harmful medical interventions.

Snake bite is an important cause of mortality and morbidity in India with an estimated 35 000-50 000 fatal bites occurring annually. Neurological deficits following vasculotoxic snake bite are either due to intracranial haemorrhage or subarachnoid bleed as a result of consumption coagulopathy. However, ischaemic strokes and acute disseminated encephalomyelitis have been reported occasionally. We hereby report a case of snake bite leading to leucoencephalopathy.

Digital swelling is a common presentation in clinical practice. Patients presenting with swollen fingers to the emergency department will often have rings on their finger, which can be removed using a variety of simple non-operative techniques or by cutting the ring off and thus avoiding any long-term consequences. ⋯ We present an unusual case of patient with psychiatric illness who presented late with a ring that had embedded upon the volar aspect of the index finger. The difficulties faced by the emergency care practitioners in such circumstances, the consequences of rings acting as a tourniquet and strategies for removal of rings on swollen fingers are highlighted.
