Consultant physician to outpatients.

Analysis of the records of the last 450 outpatients referred to me showed that the basic disorder of at least one in three lay in the psyche, and there was a large emotional element in many of the others. None were put on a waiting list for admission. Not only should physicians be generalists most of the time (whether or not they have a special interest) but most medical problems are best dealt with by the GP. Only occasionally can the physician attach a precise diagnosis to a patient who has been an obscure problem to his GP, and the physician's most important function is to reassure the patient and explain his symptoms. Routine investigations seldom benefit the patient. If there could be a more equitable distribution of GPs of high quality with good back-up facilities fewer general and many fewer specialist physicians would be needed.

Effects of posttraining injection of cholinergic agonists and antagonists into the amygdala on retention of passive avoidance training in rats.

Rats were given a single footshock while licking a water tube and tested 24 hr later for retention of the footshock experience. A single bilateral injection of a subseizure dose of physostigmine into the amygdala applied immediately, but not 18 hr, after the footshock imparied retention. This effect appeared to be somewhat localized, as physostigmine injected into the hippocampus or lateral ventricles did not disrupt retention. Conversely, a subseizure dose of atropine sulfate into the amygdala, given immediately or 18 hr after the footshock did not impair retention. Atropine injected concurrently with physostigmine into the same amygdaloid loci counteracted a potential physostigmine-induced retention deficit. Injection of carbachol into the amygdala also impaired retention; however, carbachol precipitated seizures and possibly exerted proactive consequences on performance. The time-dependent nature of the deficit following physostigmine is consistent with the view that injection of cholinergic agonists into the amygdala disrupts memory for the footshock experience.

Deep venous thrombosis in acute spinal cord injury: a comparison of 125I fibrinogen leg scanning, impedance plethysmography and venography.

Twenty acute spinal cord injury patients were surveyed for deep venous thrombosis (DVT) by 125I fibrinogen leg scanning, impedance plethysmography (IPG), and venography. Leg scanning was a more sensitive indicator of thrombotic events than IPG or venography. IPG was a reliable indicator of accumulated thrombosis. The incidence of dvt assessed by leg scanning alone was 100 per cent. Its occurrence as determined by either of the screening techniques was found to be considerably greater than those of previous reports.
