(18)FDG uptake during induction chemoradiation for oesophageal cancer fails to predict histomorphological tumour response.

To determine whether [(18)F]-fluorodeoxyglucose-positron emission tomography (FDG-PET) could predict the pathological response in oesophageal cancer after only the first week of neoadjuvant chemoradiation. Thirty-two patients with localised oesophageal cancer had a pretreatment PET scan and a repeat after the first week of chemoradiation. The change in mean maximum standardised uptake value (SUV) and volume of metabolically active tissue (MTV) was compared with the tumour regression grade (TRG) in the final histology. Those who achieved a TRG of 1 and 2 were deemed responders and 3-5 nonresponders. In the responders (28%), the SUV fell from 12.6 (+/-6.3) to 8.1 (+/-2.9) after 1 week of chemoradiation (P=0.070). In nonresponders (72%), the results were 9.7 (+/-5.4) and 7.1 (+/-3.8), respectively (P=0.003). The MTV in responders fell from 36.6 (+/-22.7) to 22.3 (+/-10.4) cm(3) (P=0.180), while in nonresponders, this fell from 35.9 (+/-36.7) to 31.9 (+/-52.7) cm(3) (P=0.405). There were no significant differences between responders and nonresponders. The hypothesis that early repeat FDG-PET scanning may predict histomorphologic response was not proven. This may reflect an inflammatory effect of radiation that obscures tumour-specific metabolic changes at this time. This assessment may have limited application in predicting response to multimodal regimens for oesophageal cancer.

Onset of sucrase-isomaltase deficiency in late adulthood.

Sucrase-isomaltase deficiency is a rare disorder usually manifested as diarrhea in infancy. The presentation of such a deficiency in adulthood is even more rare, particularly when the individual has no history of childhood diarrhea. After a literature search, the 59-yr-old patient we report is the oldest to have been identified with this condition. The difficulties encountered in diagnosis when such a case occurs at this age that have not previously been reported are highlighted.

The safety and tolerability of citalopram.

Since citalopram was first approved in 1989, it has been prescribed to an estimated > 600 000 patients. An integrated safety database has been prepared, including data from 3107 patients from 24 clinical trials. In placebo-controlled trials, nausea, dry mouth, somnolence, increased sweating, tremor, diarrhoea, and ejaculation failure, mostly of mild to moderate severity, occurred significantly (p < 0.05) more frequently with citalopram. The excess incidence of these events over placebo was always less than 10%. In pooled comparative studies, citalopram's tolerability profile was similar to that of other selective serotonin reuptake inhibitors (SSRIs) and superior to that of tricyclic antidepressants (TCAs). Spontaneous adverse event reports arising from clinical use have confirmed the safety profile defined during the trials programme. Specific monitoring of all serious adverse events from around 10 000 patients receiving citalopram in clinical trials (including small open studies) has indicated a low potential for convulsions and extrapyramidal effects. There is no evidence of withdrawal phenomena on abrupt discontinuation, no clinically relevant effects on cardiac or laboratory parameters, and little or no effect on psychomotor function. When taken in overdose alone, citalopram appears to have a relatively wide margin of safety. Citalopram has been well tolerated in both short- and long-term use, and the profile seen in trials has been confirmed in the clinic.

A novel sustained-release formulation of ibuprofen provides effective once-daily therapy in the treatment of rheumatoid arthritis and osteoarthritis.

The efficacy and safety of a novel sustained-release formulation of ibuprofen given once-daily was compared with conventional-release ibuprofen tablets 400 mg given four times daily, in a single-blind, parallel-group study. This study was conducted at 84 general practice centres throughout the UK among patients with osteoarthritis or rheumatoid arthritis. An unequal randomisation in the ratio of 4:1 was carried out, with 463 patients who received sustained-release and 115 who received conventional-release ibuprofen providing evaluable data. In this study sustained-release ibuprofen was shown to be a more effective alternative to conventional ibuprofen therapy for the treatment of arthritic diseases in general practice, offering the convenience of once-daily dosing and the associated potential benefit of improved patient compliance.
