Slipped upper femoral epiphysis--a case of a 'dodgem hip'.

A 15-year-old male patient of slim habitus presented three times over 3 days to the emergency department. Four weeks prior to the first attendance, he apparently injured his left knee in a sudden jolt whilst going on a 'bumper car' (dodgems) at a funfair. Since this incident, he had walked with a limp due to the pain in his left knee.

Spontaneous retro- and parapharyngeal haematoma caused by intrathyroid bleed.

A case of spontaneous haemorrhage into the retropharyngeal and parapharyngeal space secondary to bleeding from a thyroid cyst is described. While many conditions are known to cause this entity, no previous papers have reported a thyroid cyst to cause such extensive haemorrhage. Haemorrhage in these spaces is of particular importance as it causes rapid airway compromise and can be life-threatening.
