Psoas abscess is an uncommon condition. Most patients presented with only non-specific symptoms leading to difficulty in making an early diagnosis. In more than half of these patients, the psoas abscesses were secondary, the aetiology of which differed from reported overseas experience.
Methadone overdose is expected to result in intoxication simulating the other opioids. We report a case of hypoglycaemia following accidental methadone ingestion. A 21-year-old woman presented to a local accident and emergency department 10 hours after ingestion of 800 mg of methadone. She was found to have coma, respiratory suppression, hypotension, prolonged QTc and hypoglycaemia. The hypoglycaemia was reversed by dextrose replacement. The patient required intubation and inotropic support because of cardio-respiratory instability. She eventually recovered without consequence. To date, this is the first reported case of methadone overdose induced hypoglycaemia.
A couple of spouse mistook the Gelsemium elegans Benth. collected in countryside for Mussaenda pubescens Ait. f. and suffered toxicity soon after ingestion. One went into respiratory failure necessitating intubation and the other developed dizziness. The morphological differences between Gelsemium elegans Benth. and Mussaenda pubescens Ait. f. may not be easily recognised by the general public. Close monitoring and respiratory support are the cornerstones of management.
Hong Kong Journal of Emergency MedicineWith the advance in diagnostic radiology, penetrating atherosclerotic ulcers of the aorta become increasingly recognised in our daily practice. However, their natural history and treatment are not well defined. We report a case of penetrating atherosclerotic ulcer at the aortic arch and review the literature. (Hong Kong j. emerg.med. 2009;16:246-251)
Sodium hypochlorite is widely used as an irrigating solution in dental practice. Despite its safe properties, serious complications can result from inadvertent use. We report a patient presenting to the accident and emergency department for sodium hypochlorite accident during dental root canal therapy. The management of this dental emergency condition is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
