We examined 24-hour melatonin rhythms from 20 patients with seasonal affective disorder (SAD) and 20 healthy volunteers. Patients and controls were individually matched for age, sex, and month of study. Plasma samples were taken at hourly intervals, and were assayed for melatonin by radio-immunoassay. The 24-hourly melatonin estimations for each individual… (More)
Ten patients with seasonal affective disorder received the following treatments for 5 days each: (a) artificial daylight (2500 lux) from 20.00 to 23.00 and from 07.00 to 10.00 hours; (b) red light (300 lux) from 20.00 to 23.00 and from 07.00 to 10.00 hours; (c) artificial daylight (2500 lux) from 22.00 to 23.00 and from 07.00 to 08.00 hours. The… (More)
The rates of middle ear disease in 70 patients with schizophrenia from a defined catchment population were compared with the rates in 359 nonpsychiatric controls who were matched for age, sex and general practice. A relative risk (odds ratio) of middle ear disease in schizophrenia of 1.92 was found. This was raised to 2.29 when ear disease occurring after… (More)
OBJECTIVES Specialist early intervention services (EIS) for people aged 14-35 years with first episodes of psychosis (FEP) have been commissioned throughout England since 2001. A single estimate of population need was used everywhere, but true incidence varies enormously according to sociodemographic factors. We sought to develop a realistically complex,… (More)
The urinary excretion of 6-sulphatoxymelatonin (aMT6s) from 2400 to 0600 h was significantly increased following the treatment of ten normal volunteers with a phospho diesterase inhibitor (rolipram 1 mg 8 h for 24 h). The urinary excretion of the metabolite from 0600 to 1200 h was significantly reduced after treatment with rolipram.
