Transcending the technology of telemedicine: an analysis of telemedicine in North Carolina.

This study investigated the telemedicine program at East Carolina University School of Medicine. In-depth interviews, organizational texts, and archival records provided data for a case study that sought to understand what telemedicine is to organizational members and how they came to create this contextual reality. The goal of this study was to apply interpretive paradigmatic assumptions in the privileging of telemedicine as the very context of the organization. The findings explain how organizational members make sense of this new way of providing health care. Organizational members' talk revealed that telemedicine is multifaceted: It is access, an economic tool, education, technology, and a grant activity. With the single exception of technology, these themes emerged equally, regardless of whether the telemedicine provider was located at the urban hub site or the rural spoke site. Interestingly, members at both locations talked about critical events in relation to receipt of grant or financial support for new projects. Implications for future research are advanced.

Closed cervical spine trauma associated with bilateral vertebral artery injuries.

Bilateral vertebral artery injuries in closed cervical spine injuries are uncommon, but early recognition and treatment are important to prevent neurological deterioration. A case of bilateral vertebral injuries in a 35-year-old motor vehicle accident victim is presented, and the current literature is reviewed.

An analysis of the suitability of home health visits for telemedicine.

To determine what percentage of traditional home health nursing visits could be done by telemedicine, we carried out a retrospective review of nursing charts (clinical records). Data of two types were recorded. The objective data, which were abstracted from the records, included demographic information, patient assessments, teaching activities and interventions. The subjective data were the opinions of four observers as to whether the visit could have been done using currently available telemedicine technology. Records were sampled randomly for patients who had received home nursing care from three home health agencies in rural and urban areas during the winter and summer of 1996. A 54-item coding instrument was applied to 906 different charted home nursing visits. For 412 (46%) of these, the on-site nursing could reasonably have been replaced by telenursing. Significant factors determining the possible use of telenursing included primary diagnosis, number of interventions and patient age. Among the 10 most common primary diagnoses, the most amenable to telenursing care were chronic airway obstruction and joint disorders; the least amenable were coagulation disorders and anaemia. Telenursing visits could substitute for a substantial fraction of on-site home nursing visits. This has important implications in terms of reducing the cost of home nursing care.

Impact of emergency medicine residents on ancillary test utilization.

The effect of the addition of emergency medicine residency on the use of ancillary testing in a teaching hospital's emergency department (ED) staffed previously by emergency medicine board-certified physicians was studied. Prospectively, the utilization of three common ancillary tests (electrolyte levels, X-ray, or electrocardiogram) for four common chief complaints of patients eventually discharged from the ED was evaluated. A 12-month period before and a 15-month period after introduction of an emergency medicine residency program were compared. The mean number of ancillary tests utilized by the ED attending physicians working with residents was compared with the mean number of tests generated by the same physicians (all emergency medicine board-certified) for the same complaints in the year before the residents' arrival. There was no significant difference in test use before and after introduction of the residency (P = .66). Faculty use of tests was also unaffected by the concurrent presence of residents (P = .068). These results show that the use of testing for a sample of common ED complaints was not affected by the introduction of emergency medicine residents to a previously emergency medicine board-certified staff in one community teaching hospital.

Local anesthetics.

BACKGROUND: Dermatology is dependent upon the effects of local anesthetics for diagnostic and therapeutic interventions. A working knowledge of the drugs' actions and interactions is necessary for anyone aspiring to optimize the benefits derived from the use of local anesthetic agents. OBJECTIVE: This article reviews nerve physiology, pharmacology, classification of local anesthetics, adverse reactions (toxic, drug, allergic), local anesthetic use in pregnancy, alternatives to the "-caine" anesthetics, methods for reducing the pain of infiltration, and new agents under development. CONCLUSION: Local anesthetics are safe and effective. With the understanding of the actions and interactions of this class of drugs, maximum patient safety and satisfaction can be achieved.

Study of bound phospholipase activities of fungal mycelia using an organic solvent system.

It has been possible to demonstrate and characterize high phospholipase activities in mycelia of Rhizopus arrhizus and Mucor javanicus by use of a system in which substrates were dissolved in diisopropyl ether. Such activities were associated with bound enzymes and would have been difficult to detect using aqueous assay systems. In both cases, phosphatidylcholine hydrolysis was by phospholipase A1 (EC 3.1.1.32) activity followed by the action of lysophospholipase (EC 3.1.1.5). Phospholipase D (EC 3.1.4.4) activity was also detected. The methods used appear to be of general applicability for the detection and study of insoluble phospholipases.
