Severe psychosis due to Cushing's syndrome in a patient with a carcinoid tumour in the lung: a case report and review of the current management.

Severe psychosis in patients with Cushing's syndrome is a rare occurrence and can be extremely resistant to medical therapy. We describe a case of a 51-year-old Afro-Caribbean female patient, with refractory severe hypertension (initially resistant to polypharmacy) and gradual development of severe psychosis secondary to ectopic Cushing's syndrome, who was subsequently diagnosed to have a carcinoid tumour in her lung. Her psychotic episodes - secondary to hypercortisolism and initially refractory to the medical therapy - subsided only after the resection of the carcinoid tumour in her right lower pulmonary lobe.

Practical assessment of the display performance of radiology workstations.

The performance of 14 primary clinical display monitor workstations in use in the Radiology Department of a large acute NHS Trust was assessed using the methods and guidelines described by the American Association of Physicists in Medicine Task Group 18. Tests undertaken included the measurement of ambient light, display uniformity, luminance ratio, luminance response, maximum luminance and spatial resolution. Four display monitors failed to meet at least one of the test's guideline tolerances.
