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.

A 1-year-old child with no pre-existing cardiac or respiratory disease developed frank pulmonary oedema after administration of a neostigmine-glycopyrrolate mixture to reverse neuromuscular blockade during general anaesthesia. Possible cardiac and extra-cardiac factors that could cause pulmonary oedema in this child were ruled out by appropriate investigations. As the pulmonary oedema manifested shortly after administration of the neostigmine-glycopyrrolate mixture, we concluded that neostigmine was the most probable cause. This article briefly reports the occurrence of events and successful management of perioperative pulmonary oedema.

A 30-year-old woman with chronic foot pain after an orthopaedic surgery and chronic neck pain presented to the emergency department (ED) with a history of self-rotatory vertigo with unsteadiness. She had started low-dose pregabalin, 25 mg two times a day 9 months before experiencing symptoms with the dose gradually increased to 150 mg two times a day over this period. ⋯ Pregabalin was tapered over 2 months with a complete disappearance of the symptoms. We concluded that symptoms were due to pregabalin treatment.

Platypnoea orthodeoxia is a rare clinical syndrome characterised by dyspnoea and deoxygenation exhibited in upright position with improvement in supine posture. Previously described aetiologies include cardiac (pericardial effusion or constrictive pericarditis), pulmonary (pneumonectomy, emphysema or amiodarone toxicity), abdominal (cirrhosis or ileus) or vascular (abdominal aortic aneurysm) causes. We report an unusual case of platypnoea orthodeoxia associated with patent foramen ovale and partial hepatic resection.

Case Reports
A rare presentation of an ancient disease: scurvy presenting as orthostatic hypotension.
A 49-year-old man presented to hospital with severe orthostatic hypotension, gingival dysplasia and a purpuric rash involving his extremities. The orthostatic hypotension failed to respond to fluids and, on the basis of physical examination and dietary history, the patient was given a preliminary diagnosis of scurvy (ascorbic acid deficiency). ⋯ The pathogenesis of orthostatic hypotension in the setting of scurvy appears to involve impaired catecholamine synthesis and attenuated vasomotor response to α-adrenergic stimulation. We believe that this case describes a rare presentation of scurvy and highlights a previously under-reported connection between scurvy and vasomotor instability.
