Platypnoea Orthodeoxia syndrome is defined by dyspnoea and hypoxaemia exacerbated by orthostatic positioning and alleviated in recumbency. This condition has been reported in association with pulmonary, hepatic and cardiac disease. ⋯ A Patent Foramen Ovale (PFO) with a right to left shunt was evident on echocardiogram employing colour doppler and agitated normal saline studies. Definitive management, with closure of the patent foramen ovale lead to a complete resolution of symptoms and normalisation of arterial blood gas parameters in both the supine and erect positions.

Case Reports
Case of idiopathic isolated unilateral hypoglossal nerve palsy with spontaneous recovery.
Isolated hypoglossal nerve palsy is uncommon because of its intimate relationship with the other lower cranial nerves. Keane reported that tumours, predominantly malignant, were the most common cause of hypoglossal nerve palsy. We report a case of isolated idiopathic unilateral hypoglossal nerve palsy in a 45-year-old Caucasian male where no cause could be identified despite extensive investigations. ⋯ In the absence of a cause, an early referral to the speech and language therapist was made and interestingly our patient made an almost complete recovery within 18 months of onset. In a small case series, it has been reported that though rare, idiopathic hypoglossal nerve palsy has an excellent outcome in most cases, similar to the more common idiopathic seventh cranial nerve palsy (Bell's Palsy). We recommend an early referral for physiotherapy in such cases.
