Comparative Study
The chest radiograph in cystic fibrosis: a new scoring system compared with the Chrispin-Norman and Brasfield scores.
Scoring systems for the chest radiograph in cystic fibrosis are used to compare patients and different treatment regimens, and to monitor respiratory disease in individual patients. The Northern chest radiograph score was designed to allow one person to assess the radiological features of lung involvement in cystic fibrosis in as simple, rapid and equally reproducible manner as the established Chrispin and Norman, and Brasfield scoring systems. ⋯ The Northern system fulfils the requirements of a chest radiograph score more successfully than the Chrispin-Norman or Brasfield systems, and does not require a lateral film.

Comment Comparative Study
Critical evaluation of three chest radiograph scores in cystic fibrosis.
A number of chest radiographic scores have been developed to assess the severity of respiratory disease in cystic fibrosis but critical statistical evaluation has been limited. In particular, the chest radiograph component of the National Institutes of Health (NIH) clinical score has not previously been validated. Three different chest radiograph scores have been compared and the association between them and lung function tests investigated. ⋯ The Brasfield and NIH chest radiograph scores have very similar statistical profiles and can be equally recommended if a chest radiograph score is to be used. The RCH radiographic score appears to be less reliable. The limitations of these scores need to be understood.

Intrapleural administration of streptokinase has been shown in a few small series to be effective treatment for complicated parapneumonic effusions and pleural empyemas, but techniques of instillation of streptokinase differ. The role of streptokinase in promoting drainage was investigated prospectively in a larger series of patients with complicated parapneumonic effusions and pleural empyemas. ⋯ Intrapleural instillation of streptokinase is an effective and safe mode of treatment for complicated parapneumonic effusions and pleural empyemas and alleviates the need for thoracotomy.

It is known that automatic breathing is controlled by centres in the lower brain stem, whereas volitional breathing is controlled by the cerebral cortical centres. In hemiplegia, lesions above the brain stem result in paralysis of limb muscles. This study was performed to determine whether the diaphragm might also be affected in patients with hemiplegia. ⋯ In four of eight hemiplegic patients reduced diaphragmatic movement was present on the paralysed side during volitional inspiration when compared with automatic inspiration. The hemidiaphragm may be involved on the affected side in patients with hemiplegia.

Case Reports
Transient right-to-left shunting through a patent foramen ovale secondary to unilateral diaphragmatic paralysis.
A 57 year old patient presented with unilateral diaphragmatic paralysis and severe hypoxaemia secondary to transient right-to-left interatrial shunting through a patent foramen ovale. The final diagnosis was made because of the initial detection of a shunt while the patient was breathing 100% oxygen.
