AIM: To re-examine a population after 20 years and evaluate changes in prevalence of endodontic treatment and apical periodontitis, as well as the technical quality of root fillings. METHODOLOGY: One hundred and fifteen out of an original 200 patients living in the northern part of Sweden were re-examined with a full mouth radiographic survey after 20 years. Frequencies of root canal treated teeth, apical periodontitis and quality parameters of root fillings were registered. RESULTS: The frequency of root canal treated teeth increased significantly (P
The 2001-2003 Alaska HIV Prevention Plan describes the HIV epidemic in Alaska, provides information on populations at increased risk of infection, and recommends strategies to prevent further spread of HIV in Alaska. The HIV Prevention Plan also serves to guide uses of HIV prevention funds from the Centers forDisease Control and Prevention (CDC) within our state. This plan differs from previous plans developed by the Alaska HIV Prevention Planning Group in that it is more geographically specific, it strongly emphasizes populations at high risk, and it recommends specific interventions to reduce the spread of HIV/AIDS in Alaska.
Canada does not have enough aboriginal nurses and aboriginal nursing faculty. Consequently, there is an inadequate number of nurses to meet both on- and off-reserve and community health care staffing needs. In 2002, Health Canada asked the Canadian Association of University Schools of Nursing to facilitate a national task force that would examine aboriginal nursing in Canada. The task force engaged in an extensive literature review, conducted a national survey of nursing programs, and explored recruitment and retention strategies. In 2007, the association prepared an update on the current status. In this article, the authors review the progress made during the intervening five years in the recruitment, retention and education of aboriginal nursing students.
High morbidity rate of atopic diseases among children, including high importance of grass pollen as a sensitizing agent, determine the relevance ofstudies on diagnostic examination systems for appointment of adequate therapy. The research of the most relevant allergens for patients to excludeof duplicating and uninformative tests became urgent after development of a new type of diagnostic tests that does not require expensive equipment. The objective of this research was to evaluate the results of in vitro- and in vivo-diagnostic examinations of children with various forms of atopic disease caused by pollen of meadow grasses, and to choose the most significant prognostic parameters for the diagnosis.
277 children aged 4-16 years with various forms of atopic disease were included in the study. There were performed skin prick tests and determination of IgE-antibodies levels to allergen extracts of cocksfoot (g3), meadow fescue (g4), timothy grass (g6).
In the studied group of patients 32-50% of children have antibodies to grass allergens. There was a close correlation of antibody response on the investigated allergens, quantitative coincidence of IgE-antibodies to g3 andg4 allergens levels. IgE (g6) concentration was close to the IgE(g3) and IgE(g4) levels (85.0 ± 21.6%). Analysis of the skin tests results showed that 44% of patients have a positive response to grass allergens, and in vivo-tests results coincide with serologicaltests results, mostly in a qualitative sense. The most significant relationship was noted between in vivo and in vitro-tests in the results of testing the response to meadow fescue pollen.
Based on these data IgE concentration index to meadow fescue allergens can be used as a prognostic marker to determine the sensitization of patients with different nosology forms of allergy and can help to improve allergic diagnostics.
