Medical aspects of helicopter rescue missions involving winching of a physician

Introduction: Whereas the use of helicopters as a rapid means toreach victims and to bring them to a secure place is well-recognized,very few data are available about the value of winching physicians toprovide medical care for the victims directly on-site. We sought to studythe medical aspects of alpine helicopter rescue operations involving thewinching of an emergency physician to the victim.Methods: We retrospectively reviewed the medical reports of a singlehelicopter-based emergency medical service. Data from 1 January 2003to 31 December 2008 were analyzed. Cases with emergency callindicating that the victim was deceased were excluded. Data includedthe category (trauma or illnesses), and severity (NACA score) of theinjuries, along with the main medical procedures performed on site.Results: 9879 rescue missions were conducted between 1 January2003 and 31 December 2008. The 921 (9.3%) missions involvingwinching of the emergency physician were analysed. 840 (91%)patients suffered from trauma-related injuries. The cases of the 81 (9%)people presenting with medical emergencies were, when compared tothe trauma victims, significantly more severe according to the NACAindex (p <0.001). Overall, 246 (27%) patients had a severe injury orillness, namely, a potential or overt vital threat (NACA score between4-6, table 1). A total of 478 (52%) patients required administration ofmajor analgesics: fentanyl (443 patients; 48%), ketamine (42 patients;5%) or morphine (7 patients; 1%). The mean dose of fentanyl was 188micrograms (range 25-750, SD 127). Major medical interventions wereperformed 72 times on 39 (4%) patients (table 2).Conclusions: The severity of the patients' injuries or illnesses alongwith the high proportion of medical procedures performed directlyon-site validate emergency physician winching for advanced life supportprocedures and analgesia.

Brazilian contributions to epidemiological aspects of schistosomiasis mansoni

A review of epidemiological aspects of endemic areas for schistosomiasis, especially in Brazil, will be presented. These studies, performed by several authors from different states of the country, have been very useful in indicating the relative efficacy of control measures. For example quoting only one aspect, specific treatment was demonstrated by Brazilian researches to be the most important individual tool for morbidity control. More recently the study of risk factors in endemic areas has been seen to be a very important approach when transmission control is the final goal.

Present aspects of immunodiagnosis of schistosomiasis

Facilitated and improved by advances in molecular biology, techniques for the immunodiagnosis of schistosomiasis, including assays based on the detection of antigens circulating in the serum and/or excreted in the urine, have now reached the stage of multi-centre trials. There is a need to complement parasitological techniques as some national programmes are becoming increasingly succesful in establishng control of the disease and the classical approach frequently fails to reveal low-intensity infection. Epidemiological survey teams in some areas have tentatively started to use serology and their experience indicates that antibody detection suffies in eradicated or controlled areas with low expected prevalence but that detection of circulating antigens is needed for assessment of the incidence of infection or reinfection in areas recently brought under control. Before reagents and procedures can be recommended for routine use of national control programmes, the assays must be standardized with sera from clinically well-characterized patients in geographically defined regions, hence emphasizing the need for a reference serum bank. Implementation of serological testing, carried out by nationsl public health laboratories using standardized testing systems, would permit valid comparisons between different areas providing support for decisions regarding national health polices.

La relation ambiguë des protestantismes à la sociologie

(Résumé de l'ouvrage) What are the relations between sociology and the different religions - Christianity with its various branches, Judaism, Islam, Oriental religions, sects and New Religious Movements ? That is the question which this work, - conceived on the occasion of the XXVth Conference of the International Society for the Sociology of Religion/Société Internationale de Sociologie des Religions (SISR) - wishes to clarify. The book retraces the varied and troubled history of these relations and also reveals how in opening up its research to other religions besides the Christan, sociology is forced to redefine the very object of its field of study. What is the religious? This question, which until recently was considered impertinent, informs this book throughout. If confronts the necessity of rethinking theories and methodological appoaches which, constructed in the context of 19th and early 20th century Western Europe, prove to be rather inadequate for encompassing contemporary religious phenomena and religious manifestations in other contexts. To these new theoretical and methodological demands is added, for the sociologist, a deontological imperative, which takes on all the more importance today as the religious provokes passionate social debate.

Judaïsme et islam dans le face à face avec le protestantisme

L'islam et le judaïsme ont de nombreux points de rencontre avec le protestantisme. Si ces deux religions ne provoquent pas la sympathie des premier Réformés, l'histoire contemporaine indique des rapprochements incontestables, sur fond d'un partage de quelques traits communs entre ces trois courants du monothéisme: la pratique, la relation aux images ou au clergé, l'expression politique et communautaire des ailes radicales. L'un des intérêt de ce livre est de proposer une lecture originale et plurielle de deux dossiers importants pour le dialogue interreligieux. Chacun des deux thèmes associe les contributions d'un théologien protestant et respectivement deux intellectuels juif (David Banon) et musulman (Mohammed Arkoun).

Contrôle de la qualité des soins: aspects épidémiologiques. [Quality control of health care: epidemiological aspects].

Quality control in health care should be performed by health professionals. To do so they must define indicators, set up studies aimed at measuring and analyzing quality of care, and implement quality assurance programs in health care systems. The elements of a quality improvement program of this kind are described, with special emphasis on the contribution of epidemiology in this field.

Epidemiological aspects of American Cutaneous Leishmaniasis in a periurban area of the metropolitan region of Belo Horizonte, Minas Gerais, Brazil

In order to characterize the epidemiology of American Cutaneous Leishmaniasis (ACL) in a periurban area of the municipality of Sabará in the metropolitan region of Belo Horizonte (MRBH), an area until then considered free of the disease, a cross sectional survey was undertaken in 1990. The survey of the population consisted of 1119 interviews and 881 clinical examinations using Montenegro's skin test (MST). A low prevalence (3.7%) of positive MST was encountered. The disease had been occuring in the area for about 20 years in the form of sporadic cases. The predominant species of sandfly both in domestic areas and nearby areas of secondary vegetation was Lutzomyia whitmani. A canine survey of delayed hypersensitivity to the antigen P10,000 identified only one dog with a positive reaction out of 113 examined. The transmission of ACL in MRBH was confirmed. The occurrence of the disease in women, children and individuals with no contact with forest areas as well as the presence of potential vector species in the domiciliar environment, suggests the transmission of the disease in this environment.

Morphologic and morphometric aspects of oenocytes of Apis mellifera queens and workers in different phases of life

Oenocytes of adult workers and queens of Apis mellifera L. were studied in different ages or life stages, by means of morphometric and histologic techniques. In workers, the oenocytes were found in the head, near the mandibles and in the abdomen, immersed in the parietal fat body mainly below the sterna, close to the wax gland. In queens, two populations of oenocytes different in size and localization were found within the parietal and visceral fat body, respectively. The oenocytes of workers and queens show the presence of acid lipids and acid phosphatase. The role of these cells in the castes differences is discussed.

Theoretical aspects of graph models for MANETs

We survey the main theoretical aspects of models for Mobile Ad Hoc Networks (MANETs). We present theoretical characterizations of mobile network structural properties, different dynamic graph models of MANETs, and finally we give detailed summaries of a few selected articles. In particular, we focus on articles dealing with connectivity of mobile networks, and on articles which show that mobility can be used to propagate information between nodes of the network while at the same time maintaining small transmission distances, and thus saving energy.
