Reversible cerebral vasoconstriction syndrome is characterised by severe thunderclap headache with associated characteristic transient, multifocal, segmental vasoconstriction of cerebral arteries lasting several weeks to months. We describe a 50-years old woman who presented with a severe sudden onset occipital headache. ⋯ The pain improved gradually over the next 6 weeks. Repeat brain MR angiography at 12 weeks showed complete resolution of the segmental narrowing.

Case Reports
Severe lactic acidosis and multiorgan failure due to thiamine deficiency during total parenteral nutrition.
A 16-year-old perioperative paediatric patient presented with refractory lactic acidosis and multiorgan failure due to thiamine-deficient total parenteral nutrition during a recent national multivitamin shortage. Urgent empiric administration of intravenous thiamine resulted in prompt recovery from this life-threatening condition. Despite readily available treatment, a high index of suspicion is required to prevent cardiovascular collapse and mortality.

A 68-year-old man presented with facial cellulitis and found to have Neisseria meningitidis bacteraemia with no evidence of infection outside of the facial soft tissue. He was treated with a course of intravenous ceftriaxone and transitioned to oral amoxicillin on discharge with significant improvement of his symptoms. ⋯ In this case series we describe and summarise our case, along with the 12 cases already reported in the literature. We report this case series to highlight the importance of recognising N meningitidis in the differential in patients presenting with acute skin and soft tissue infections especially involving the periorbital, head and neck regions.

Case Reports
Twelve-year-old boy with recurrent presentations of shortness of breath: an intraluminal tracheal tumour.
A 12-year-old boy was admitted with symptoms of recurrent shortness of breath since 12 months along with mild intermittent retrosternal chest pain that had developed 3 weeks ago prior to admission. He was previously treated for asthma with no improvement. Initial posteroanterior chest X-ray (CXR) revealed no abnormality on two occasions. Lateral CXR showed a mass lesion in the distal trachea which was subsequently confirmed by a CT scan of the chest.

Sore throat is a common complaint in the outpatient and emergency room settings. Typically, little workup is necessary and includes visual inspection with or without swabs for bacterial infection. We present a case that demonstrates an important entity to be excluded by simple history and physical examination in patients presenting with pain in the throat or neck. ⋯ Most cases of spontaneous pneumomediastinum are uncomplicated, as mediastinal pressures rarely mount to dangerous levels. However, when the patient presents with distended neck veins, cyanosis or marked dyspnoea, further action is necessary. Lastly, since pneumomediastinum can be caused by oesophageal rupture and occasionally present with concurrent pneumothorax, these dangerous entities must be excluded.
