The politics of interprofessional working and the struggle for professional autonomy in nursing

This study of interprofessional work relations in a Canadian mental health team examines how nursing deployed different forms of power in order to alter the mental health division of labour, to gain administrative, organizational and content control over its own work, expand its jurisdictional boundaries by expropriating the work of other professionals, and exclude others from encroaching on its old and newly acquired jurisdictions. This is set against the context of nursing's long-standing professional project to consolidate and expand its professional jurisdiction. Using an ethnographic study of a single interprofessional mental health team in a psychiatric hospital in Canada, the paper attempts to understand the politics and paradoxes involved in realizing nursing's professional project and how the politics of professional autonomy and professional dominance are actually conducted through micro-political struggles. The data demonstrates the effects of the political struggles at the organizational and work process levels, particularly in the forms of collaboration that result. Nurses gained substantial autonomy from medical domination and secured practical dominion over the work of non-medical professionals. New forms of interprofessional collaboration were accomplished through both simultaneous and sequential micro-political struggles with psychiatrists and non-medical professionals, and the formation of political alliances and informal agreements. Nursing solidarity at the elite level and substantial effort by the elite nurses and their committed colleagues to mobilize their less enthused members were fundamental to their success. The nurses deployed political (power) strategies and tactics to organize and reorganize themselves and other professionals on multiple levels (politically, organizationally, ideologically, socially and culturally). This study reveals the complexity and robustness of micro-political dynamics in the constitution of professional and collaborative interprofessional work relations.     

PR01“A PICTURE SPEAKS A THOUSAND WORDS”– THE USE OF DIGITAL PHOTOGRAPHY AND THE INTERNET IN MONITORING FREE TISSUE TRANSFER

Purpose Post operative monitoring is crucial for the success of microsurgical free tissue transfer. Sophisticated and expensive methods are available for monitoring. We propose a novel technique using digital photography and the internet as a reliable and cost effective method to monitor free tissue transfers. Methods 163 micro‐vascular procedures were monitored using this technique over 8 months. Serial photographs taken to show flap color. Capillary refill time, pin prick‐ bleed time and color and hand held Doppler signal was recorded in the movie mode of a standard 5 mega pixel camera with duration of 15 seconds. Data was sent to the surgeon at regular intervals and or as deemed necessary. Results Analysis of the 67 cases is presented. 5 re‐explorations were done. The early diagnosis of venous congestion was possible using this technique. Timely intervention contributed to the success of the re‐explorations and these flaps could be salvaged. The file size of images was in the range of 1 MB–6 MB. The file size of an entire set of images ranged about 7 MB–9 MB. These were sent across the ADSL internet lines. Conclusion The use of the digital images and the internet allow reconstructive surgeons to have a reliable picture of the state of their free tissue transfers. This permits decrease in observer error and saves valuable time which otherwise needs to be spent to verify situations of doubt and offers an ideal solution to the logistic problem of having to visit the patient in case of doubt.     

Association between the HOXA1 A218G polymorphism and increased head circumference in patients with autism.

BACKGROUND: The HOXA1 gene plays a major role in brainstem and cranial morphogenesis. The G allele of the HOXA1 A218G polymorphism has been previously found associated with autism. METHODS: We performed case-control and family-based association analyses, contrasting 127 autistic patients with 174 ethnically matched controls, and assessing for allelic transmission disequilibrium in 189 complete trios. RESULTS: A, and not G, alleles were associated with autism using both case-control (chi(2) = 8.96 and 5.71, 1 df, p <.005 and <.025 for genotypes and alleles, respectively), and family-based (transmission/disequilibrium test chi(2) = 8.80, 1 df, p <.005) association analyses. The head circumference of 31 patients carrying one or two copies of the G allele displayed significantly larger median values (95.0th vs. 82.5th percentile, p <.05) and dramatically reduced interindividual variability (p <.0001), compared with 166 patients carrying the A/A genotype. CONCLUSIONS: The HOXA1 A218G polymorphism explains approximately 5% of the variance in the head circumference of autistic patients and represents to our knowledge the first known gene variant providing sizable contributions to cranial morphology. The disease specificity of this finding is currently being investigated. Nonreplications in genetic linkage/association studies could partly stem from the dyshomogeneous distribution of an endophenotype morphologically defined by cranial circumference.     

A philosophical yet user-friendly framework for ethical decision making in critical care nursing.

Nurses must frequently make ethical decisions. These decisions require judgment, knowledge, and skills. This article will provide one framework for ethical decision making and provide several examples of the process.     

Selective photothermolysis: contribution to the treatment of flat angiomas (port wine stains) by laser

Since 1962, lasers have been used in dermatology and have become the first choice in the treatment of superficial, vascular ectasia. Lasers are unique sources of light; they are coherent, monochromatic, collimated and intense. By careful selection of wavelength, pulse duration, and intensity, it is often possible to selectively confine a laser effect to a specific histologic structure in tissue, depending upon the tissue properties. The ideal treatment of Port Wine Stains (PWS) should irreversibly damage the ectatic vessels but minimize heating of the epidermis and superficial dermis. A theory, called selective photothermolysis, predicts the optimal combination of laser parameters of achieving this ideal treatment of PWS to be a wavelength of 577 nm, a pulse duration of 0.35-10 msec, and an energy per surface area of about 7-8 J/cm2. Laser wavelength: The wavelength of 577 nm is preferred because it: maximizes the selective absorption by hemoglobin, minimizes absorption by epidermal melanin, provides sufficient depth of penetration in the blood to coagulate 0.1 mm vessels allows penetration of light into dermis up to 1 mm. Laser pulse duration: A pulse-width in the range of 0.35-10 msec allows the temperature elevation to be uniform inside the vessel and to be confined to the vessel area. Shorter pulses superheat the red blood cells causing explosive boiling and hemorrhage. Longer pulses allow heat to diffuse away from vessels, requiring greater energies per pulse to achieve vessel damage. An increased energy per pulse increases the risk of excessive damage to surrounding tissue.(ABSTRACT TRUNCATED AT 250 WORDS)     

浅谈药品快检在实践中存在的主要问题及建议

我国是发展中国家，农村人口占全国总人口的70%。由于基层群众医药基础知识欠缺，医疗和用药水平偏低，使得假劣药品在基层出现的频率较高。特别是近几年，随着制假水平的不断提高，假劣药品在基层呈现出范围广、流通快、制售手段和形式多变的趋势，给基层稽查工作带来了新的挑战。为此，国家食品药品监督管理局在2002年编写并下发了《药品快速鉴别手册》。
