False negative angiogram in pulmonary embolism.

A 19-year-old woman presented with symptoms of pulmonary infarction and an abnormal perfusion scan compatible with pulmonary embolism. Pulmonary angiogram performed utilizing two bolus injections in the frontal plane and recorded on multiple cut films was reported as normal. This false negative angiogram points out the need for modifications in conventional pulmonary angiographic technique.

DSM III and consultation-liaison psychiatry: toward a comprehensive medical model of the patient.

The descriptive and multiaxial approaches in DSM III encourage comprehensive conceptualization of the patient. The use of explicit criteria for diagnosing syndromes facilitates communication between psychiatry and general medicine. The DSM III category Psychological Factors Affecting Physical Condition should be further elaborated into (a) Psychiatric Factors Affecting Physical Condition, and (b) Physical Condition Affecting Psychiatric Disorder. In addition, the phase of the illness these factors affect should be specified, i.e., the precipitation, course, and recovery. Somatoform Disorder should not be a diagnosis of exclusion, and the diagnostic criteria should clearly specify that conversion symptoms may be superimposed on a pre-existing physical disorder. The DSM III axes are not coherent: they include diagnostic categories, statements concerning possible relationships, and factors that might affect outcome. We propose an alternative to the DSM III Axes based on the Patient Evaluation Grid (PEG), a system comprised of four axes, including Biological Dimension, Personal Dimension, Environmental Dimension, and Assessment of Interaction Among Dimensions. Developing a comprehensive diagnostic model for both medical and psychiatric patients that can be shared by all physicians may be an important function of the liaison psychiatrist.

Sydney Eye Hospital.

This year, 1982, marks the centenary of the Sydney Eye Hospital, originally the ophthalmic department of the old Sydney Infirmary, which was founded with the settlement of the Colony in 1788. Established in 1882, the hospital was transferred to its present site 60 years ago, and it still provides ward accommodation. After alternating periods of stagnation and progress the new hospital (stage 1) was completed in 1974, with modern clinic and research facilities. It is now the largest eye hospital in the southern hemisphere and is a first-class referral centre with an annual attendance of 75,000. The Department of Ophthalmology, University of Sydney, is based at the hospital, providing undergraduate instruction and a comprehensive postgraduate training programme for Australian ophthalmologists and others in more distant continents.

A self-supporting library service in a rural region: a new look at hospital consortia.

To meet the informational needs of health care practitioners and trainees in a four-county rural area of northwestern North Carolina, the eleven-member UNIFOUR Consortium was founded as a two-year experimental project from 1978 to 1980. The consortium has several unique features: (1) it is an organization of institutions, not libraries; (2) it employs its own professional librarian who manages a central library, coordinates consortium programs, and makes regular circuit visits to all affiliated institutions; (3) the central library, where the circuit is based, is a developing community hospital library, not an established academic medical center library; and (4) it is ultimately tied to the Northwest Area Health Education Center and that organization's emerging learning resources network, which includes the Bowman Gray School of Medicine, Library, two other subregional libraries, and the libraries of all member institutions. At the end of the experimental period in 1980, member institutions voted unanimously to continue the program and assume their share of the costs.

Metabolic and functional characteristics of alveolar macrophages recovered from rats exposed to marijuana smoke.

Pulmonary alveolar macrophages were obtained by bronchopulmonary lavage from male rats after 30 consecutive days of in vivo exposure to marijuana and tobacco smoke. No significant differences were found between either group of experimental animals and controls in the number of cells recovered, the protein content per 10(6) cells, or the percentage of cells that adhered to plastic surfaces. The ability of macrophages to phagocytize viable bacteria was not affected by exposure to either marijuana or tobacco smoke in that both treatment groups ingested Staphylococcus aureus over a 60-min period as well as did control cells. Differences were found between the groups, however, with respect to cellular metabolism. Marijuana smoke inhalation caused a small decrease in the amount of oxygen consumed by macrophages during phagocytosis, as compared with control cells. This may have been reflected in the even greater decrease in superoxide formation observed during particle engulfment by these treated cells. Tobacco smoke, on the other hand, increased oxygen consumption and was without effect on superoxide release. Neither tobacco nor marijuana smoke treatment had an effect on the direct oxidation of glucose via the hexose monophosphate shunt. Our results indicate that, despite several metabolic alterations in response to marijuana and tobacco smoke, alveolar macrophages were not compromised with respect to their ability to ingest a particulate challenge.

The role of intensive care units.

The indications for intensive care are discussed. Selection of patients should be based upon the apparent reversibility of disease processes and the likelihood of producing worthwhile relief of suffering. Admission statistics for one II-bed unit are also presented, and survival rates exceeding 90% of three "model" conditions-namely, fat embolism, tetanus and Gullain-Barré syndrome-are reported. The hospital costs for treating critically ill patients are approximately three times those for treating the "average" patient.
