Myocardial hamartoma as a cause of VF cardiac arrest in an infant

We describe the aspiration of a traumatic haemopneumo-thorax and an unexpected anteroposterior chest radiograph finding after the procedure. Chest aspiration is now routine emergency management for spontaneous pneumothorax. There have been no previous documented reports of this clinical scenario of radiological deterioration with clinical improvement after aspiration of a haemopneumothorax. A 31 year old man with prosthetic aortic valve replacement presented with sudden onset of colic right flank pain. Analysis of the urine revealed haematuria, and the international normalised ratio was suboptimal. The patient was misdiagnosed as having ureteral colic. On the second day, an ultrasound showed no signs of obstructive uropathy, and there was no evidence of absent function on intravenous pyelogram. Computed tomography with contrast agent was performed and revealed a right renal infarction. Renal angiography demonstrated total occlusion of the right renal artery. Fibrinolytic therapy and angioplasty were unsuccessful. To our knowledge, aortic prosthetic valve thrombus as a source of renal artery embolism mimicking renal colic has not been reported previously. This case underlines the importance of renal colic as a manifestation of renal infarction in patients with prosthetic valves and the need for a high index of suspicion of renal embolism. A case is presented of unilateral tension pneumothorax associated with flail chest and pulmonary contusions in a spontaneously ventilating patient after a fall. The tension element was not suspected until chest x ray was available, nor was immediate needle thoracocentesis performed. No morbidity resulted as a consequence. This case highlights the difficulty in deciding whether or not tension pneumothorax is the predominant cause of respiratory distress in a patient with multiple chest injuries. It provides further evidence challenging some of the doctrine on how to treat suspected tension pneumothorax. The use of colchicine, a treatment for acute gout and familial Mediterranean fever, is limited by its toxicity. A relatively low dose of colchicine may be fatal. After a colchicine overdose, monitoring should include 6–12 hourly serum troponin measurements. A rising troponin level predicts cardiovascular collapse and is an indication for more intensive management. A 50 year old woman with a previous diagnosis of epilepsy presented to the emergency department with a generalised seizure. Her admission ECG showed QT prolongation secondary to bradycardia and a subsequent seizure in the department demonstrated that these events were secondary to cerebral hypoperfusion during episodes of torsades de pointes. This case illustrates how long QT syndrome can masquerade convincingly as epilepsy, delaying treatment and exposing the patient to a high risk of sudden cardiac death. Careful ECG analysis is recommended for all patients presenting with seizures. A case is presented in which the decision to admit and treat an adult with musculoskeletal pain and pyrexia was based on her markedly raised c-reactive protein (CRP). At the time of admission she was apyrexial and the CRP was the only haematological investigation that was out of the normal range. She subsequently became precipitously septic with pneumococcal bacteraemia and meningitis. The CRP is an important investigation for emergency departments.
