RESUMEN
Oromandibular dystonia (OMD) is characterised by sustained or repetitive involuntary movements of the jaw, face, and tongue. People with the condition may present to their dentist, general practitioner, or a secondary care specialist with non-specific symptoms including jaw or facial pain, bruxism, subluxations or dislocations of the jaw; fractured teeth or dental restorations, or both; or jaw tremor. Many clinicians are not aware of the disorder and this can lead to delayed diagnoses, unnecessary complications, and inappropriate treatment. OMD is an important diagnosis not to miss because referral for specialist management can provide good long-term results. To aid early, accurate diagnosis, this paper focuses on the key clinical features of the disorder and its dental and medical mimics.

A 61-year-old woman with secondary progressive multiple sclerosis presented on six occasions over a 2-year period with severe hypothermia (31-33.5 degrees C). This resulted in numerous multi-system complications comprising acute pancreatitis, hepatitis, gastrointestinal haemorrhage, psychiatric disturbance, bradycardia, paradoxical sweating, thrombocytopenia, anaemia and raised inflammatory markers. Septic screens were consistently normal. On each occasion she was successfully treated with passive external rewarming and made a complete recovery. This is the first reported case of such extensive sequelae in a single patient with recurrent hypothermic episodes. This unusual patient provides an invaluable insight into the natural history and pathophysiology of hypothermia. The case report is followed by a review of dysfunctional thermoregulation and pathophysiology of hypothermia-induced multi-system complications. A key learning point is to recognise that the clinical manifestations of hypothermia may be widespread and serious but are nonetheless reversible. In addition, one should consider the differential diagnosis of covert hypothermia in those patients with episodic confusion, as hypothermia is under-recognised, particularly in older people, who are prone to accidental hypothermia, and in those with common neurological conditions, such as stroke, head injury and multiple sclerosis, that may have suboptimal thermoregulation.

John Ruskin (1819-1900) is chiefly remembered for his works on painting and architecture, and for his powerful and original prose style. In middle age, he suffered recurring episodes of delirium with visual hallucinations and delusions. At about the same time, his writing developed a disjointed polemical character, with cryptic and intemperate elements that disorientated some readers. The nature of Ruskin's 'madness' is a key to understanding his later writing career but the psychiatric explanations given by many of his literary biographers seem unsatisfactory. Ruskin left numerous clues about the illness in his diaries, correspondence and publications. It is likely that he had a relapsing-progressive neurological disorder with neuropsychiatric manifestations. It could have been a fluctuating metabolic or immunological encephalopathy, but the diagnosis that best fits the time course of his illness and the prior history of mood disorder and of migraine with aura is Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL). Whatever the pathology, its first effects on frontal lobe function may have actually enhanced Ruskin's creative energy for a long time before stepwise cognitive impairment degraded his ability to write.

Pulmonary arterial dissection is an extremely rare and usually lethal complication of chronic pulmonary hypertension. The condition usually manifests as cardiogenic shock or sudden death and is therefore typically diagnosed at postmortem examination rather than during life. However, recent isolated reports have described pulmonary artery dissection in surviving patients. The first case of pulmonary artery dissection in a surviving patient with cor pulmonale caused by chronic obstructive pulmonary disease is presented. The aetiology, pathophysiology, and clinical presentation of pulmonary artery dissection are reviewed and factors that may aid diagnosis during life are discussed.
