Structured interviews were carried out with 30 randomly selected general practitioners, to discover how they perceived and handled psychological problems in their patients. In addition, the doctors' perceptions and expectations of their professionals who might assist in the management of such problems were examined. Much of the previously published work was confirmed by the present investigation, but some new information was also uncovered. Thus, although almost all the GPs were sympathetic towards the wish of some clinical psychologists to work at the primary health care level, almost half the doctors would not want a psychologist within their practice, even if finance and accommodation were not problematic. Clinical psychologists were viewed, primarily, as therapists and, as such, were mostly expected to provide a regular part-time service to the practice. Only a minority of GPs wished to acquire skills from clinical psychology, but a large majority were in favour of direct referrals. The results of this study are discussed in terms of their implications for clinical psychology services.
The Italian AIDS hot-line has recently completed its first two operational years. Established as an emergency service, it was initially overloaded with calls, under the emotional impact of a new disease. As the average number of calls settled to around a hundred per day, a wider approach aimed at the concerns raised by callers has been possible. A particular effort has been made to handle psychological and social aspects of HIV infections. A large proportion of the questions analyzed (62,500) deal with doubts about transmission (30%), reliability of diagnostic tests (15%), and handling individual situations. Some categories of callers, such as drug users, parents or relatives of HIV-infected people, and seropositives often require experienced telephone counselling. HIV-positive callers follow the proportional distribution of AIDS cases in Italy: intravenous drug users forming the majority, followed by homosexuals and finally heterosexual subjects (reaching 10%, a value in accordance with trend projections). The demand for advice has increased over time, together with an evident refinement of question content.
The author describes attitudes held by nonpsychiatric physicians that are responsible for poor psychological handling of patients, including low interest in psychosocial aspects of illness, judgment of and disinterest in hypochondriasis or conversion reaction, avoidance of psychotic or terminally ill patients, and anger toward patients with unpleasant characteristics. He discusses reasons for these attitudes and suggests that medical schools increase psychological education and psychiatry departments increase the relevance of their teaching.

Withdrawal of benzodiazepines is currently advised for long-term benzodiazepine users because of doubts about continued efficacy, risks of adverse effects, including dependence and neuropsychological impairment and socio-economic costs. About half a million people in the UK may need advice on withdrawal. Successful withdrawal strategies should combine gradual dosage reduction and psychological support. The benzodiazepine dosage should be tapered at an individually titrated rate which should usually be under the patient's control. The whole process may take weeks or months. Withdrawal from diazepam is convenient because of available dosage strengths, but can be carried out directly from other benzodiazepine. Adjuvant medication may occasionally be required (antidepressants, propranolol) but no drugs have been proved to be of general utility in alleviating withdrawal-related symptoms. Psychological support should be available both during dosage reduction and for some months after cessation of drug use. Such support should include the provision of information about benzodiazepines, general encouragement, and measures to reduce anxiety and promote the learning of non-pharmacological ways of coping with stress. For many patients the degree of support required is minimal; a minority may need counselling or formal psychological therapy. Unwilling patients should not be forced to withdraw. With these methods, success rates of withdrawal are high and are unaffected by duration of usage, dosage or type of benzodiazepine, rate of withdrawal, symptom severity, psychiatric history or personality disorder. Longer-term outcome is less clear; a considerable proportion of patients may temporarily take benzodiazepines again and some need other psychotropic medication. However, the outcome may be improved by careful pharmacological and psychological handling of withdrawal and post-withdrawal phases.

We hope that general practitioners will consider counselling their dying patients more actively, including those in hospital where terminal care may be poorly handled psychologically. This entails a major change in training which we hope is taking place through vocational training schemes. We feel a change in attitude to be necessary by many general practitioners who often deal with death by evasion and untruth.
It is of great emotional impact to lose upper or lower limbs; adequate psychological handling of such a loss is described. Mourning will bary if amputation was programmed or carried out without warning. In the group, individual conflict, depression and the problem of function loss are handled, more than problems of the patient vis-a-vis the institution. Characteristics of the group are described.

The effects of differential psychological stress on serum triglyceride and aortic cholesterol levels were investigated in two experiments. In the first, rats with an unknown infant handling history purchased as adults from a standard supplier were subjected to predictable, controllable shocks; unpredictable, uncontrollable shocks; or the apparatus or their home cages with no shocks, for 30 days. All were maintained on a cholesterol-supplemented diet except during the daily 51-min stress sessions. The amounts eaten were equated among the groups. The results that the shocked rats had significantly lower terminal levels of serum triglycerides, and those receiving unpredictable, uncontrollable shocks had significantly less aortic cholesterol, than the nonshocked groups, which did not differ from each other in either measure. In the second experiment, rats born in this laboratory were either handled or left undisturbed in infancy and were exposed to a diet and differential stress conditions as adults. Animals handled in infancy had significantly lower aortic cholesterol than nonhandled animals across all stress conditions. In addition, those exposed to unpredictable, uncontrollable shocks had lower aortic cholesterol than those exposed to predictable, controllable shocks, and both had lower aortic cholesterol than the nonshocked group. Similar differential stress effects across stress conditions were seen in all the rats' serum triglyceride levels in Experiment 2. The effects of infantile handling did not interact with the stress effects, and neither could be accounted for by group differences in amount of the diet eaten or weight gained.

Vulnerability to sudden death was produced in laboratory rats by manipulating their developmental history. Rats who were reared in isolation died suddenly when placed in a stressful swimming situation. Handling of these singly-housed rats from 25 to 100 days of age potentiated the phenomenon. However, animals who were group housed did not die even when they had been previously handled.
When morphine administration is paired with a distinctive context, tolerance to morphine's analgesic effects comes readily under the associative control of the drug-paired context. These associative tolerance effects are eliminated when a relatively short (i.e., 6 h) interdose interval (IDI) is used for conditioning. Contemporary models of learned tolerance explain the absence of learning at short IDIs by positing that residual morphine effects from a recent drug exposure disrupt the formation of drug-context associations. The present studies examined the impact of unsignaled morphine injections given 6 h prior to drug-context pairings on the development of associative tolerance. Analgesia was measured by the tail-flick method, and tolerance levels were assessed by dose-response curve methodology. Morphine preexposure had no detectable influence on the acquisition of associative tolerance when rats were tested immediately after conditioning, after a 30-day rest interval, or after a 30-day period of daily saline injections in their home-cage environment. These data suggest disruption of associative tolerance effects at short IDIs is not attributable to residual effects of morphine from the immediately preceding trial.
The influence of norepinephrine (NE) on the acquisition of a conditioned odor preference and enhanced focal uptake of [14C]2-deoxyglucose (2-DG) within the olfactory bulb was assessed in neonatal rat pups. On postnatal day (PN) 6, pups were injected with either an NE receptor agonist (isoproterenol), NE receptor antagonist (propranolol or timolol), or saline before one-trial odor conditioning. The experimental conditioning group received a 10-min exposure to an odor (peppermint) and reinforcing tactile stimulation similar to that received from the dam. Control groups received only the odor, only the tactile stimulation, backwards presentation of the odor and tactile stimulation or neither of these stimuli. The next day, pups were either tested for an olfactory preference (Expts. 1 and 2) or assessed for differential olfactory bulb activity using the 2-DG technique (Expt. 3). The results indicate that early odor experience with either tactile stimulation or isoproterenol is sufficient to produce a learned behavioral preference and enhanced focal 2-DG uptake within the olfactory bulb. Moreover, an NE receptor blocker injected prior to training with odor and tactile stimulation blocks the acquisition of both behavioral preference and the enhanced 2-DG uptake. In Expt. 4, the effects of tactile stimulation and isoproterenol were further assessed. An odor paired with a moderate level of either of these stimuli produces learning. However, the simultaneous presentation of a moderate level of these stimuli paired with an odor does not result in an odor preference. An odor preference may be reinstated by simultaneous presentation of these stimuli, provided the level of each of these stimuli is too low to produce an odor preference when presented alone with an odor. These data suggest that exogenous NE and tactile stimulation are additive in their effect on learning. These results are discussed in terms of the neural mechanisms underlying reinforcement in infant rats.
