Randomized Controlled Trial Comparative Study Clinical Trial
Corticosteroid trials in non-asthmatic chronic airflow obstruction: a comparison of oral prednisolone and inhaled beclomethasone dipropionate.
One hundred and twenty seven adults considered on clinical grounds to have non-asthmatic chronic airflow obstruction entered a randomised, double blind, placebo controlled, crossover trial comparing the physiological response to inhaled beclomethasone dipropionate 500 micrograms thrice daily with oral prednisolone 40 mg a day, both given for two weeks. One hundred and seven patients completed the study. Response was assessed as change in FEV1 and FVC measured on the last treatment day, and as change in mean peak expiratory flow (PEF) over the final seven days of treatment from home PEF recordings performed five times daily. ⋯ Only 21 of the 44 responders showed a response to both forms of treatment. Inhaled beclomethasone dipropionate 500 micrograms thrice daily was inferior to oral prednisolone 40 mg per day, but better than placebo, in producing improvement in physiological measurements in patients thought to have nonasthmatic chronic airflow obstruction. It was, however, an effective alternative in over half of those showing a response to prednisolone.

Case Reports
Apparent response of small cell lung cancer to an extract of mistletoe and homoeopathic treatment.
A patient with small cell lung carcinoma was treated initially with extracts of mistletoe and homoeopathic treatment and appeared to respond. Subsequently radiotherapy was given and the patient lived for five years seven months, which is much longer than is usual with this type of tumour.

Case Reports
Bilateral recurrent haemorrhagic pleural effusion in asymptomatic chronic pancreatitis.
In a case of bilateral recurrent haemorrhagic pleural effusion due to asymptomatic pancreatitis the diagnosis was suggested by the presence of amylase in the pleural fluid when other possible causes had been excluded. Abdominal computed tomography and laparotomy confirmed the diagnosis. No communications could be seen between the peritoneal and pleural space at laparotomy.

Comparative Study
Topical nasal anaesthesia for fibreoptic bronchoscopy: patients' preference for lignocaine gel.
Two techniques for anaesthetising the nose before fibreoptic bronchoscopy have been compared. Fourteen of 16 patients given lignocaine spray found it unpleasant, compared with three of 20 patients given lignocaine gel. The two forms of local anaesthetic were found to be equally effective. Lignocaine gel is therefore recommended for topical nasal anaesthesia before fibreoptic bronchoscopy.
