A case of acute granulomatous appendicitis due to Strongyloides stercoralis infection in an HIV-positive patient is described. To our knowledge this is the first case presented in the literature. 相似文献

Visceral leishmaniasis is a vector-borne systemic infection, which affects half a million people each year in many areas of the world. Typical disease manifests with fever, hepatosplenomegaly, pancytopenia, and progressive deterioration of the host. Although molecular methods appear promising as a non-invasive diagnostic tool, definite diagnosis still relies on the demonstration of the parasite in tissue. Pentavalent antimonial compounds remain the mainstay of treatment worldwide, except in India. During the past decade, short courses of lipid formulations of amphotericin B were assessed and proved effective; however, their cost precludes their wide use in developing countries. Miltefosine, an oral active agent, was recently identified, and might fulfil our expectations for an effective, safe, easily administered and affordable antileishmanial treatment. 相似文献

Effects of lipids on thrombotic mechanisms in atherosclerosis 总被引:3,自引:0,他引:3

Cholesterol lowering therapy markedly reduces the frequency of subsequent cardiovascular events and is associated with a modest degree of angiographic regression of atherosclerotic lesions. There is a strong association between lipids and fibrinogen, plasminogen activator-1, and activated factor VII levels. Low density lipoprotein may be thrombogenic whereas high density lipoprotein protects against thrombosis. Lipoprotein (a) may affect atherosclerosis and thrombosis mainly by binding to fibrin and attenuating the fibrin-enhanced plasminogen activation. Tissue factor-complex initiates coagulation by activating factor X and factor IX leading in the presence of calcium to the generation of thrombin. Lipid lowering treatment with statins stabilizes atheromatous plaque and has antithrombotic effects. Therefore there are links between lipids and the haemostatic mechanisms which affect atherosclerotic, vasomotor and thrombotic components of ischemic heart disease. 相似文献

Background
In the era of cost containment, managers are constantly pursuing increased organizational performance and productivity by aiming at the obvious target, i.e. the workforce. The health care sector, in which production processes are more complicated compared to other industries, is not an exception. In light of recent legislation in Greece in which efficiency improvement and achievement of specific performance targets are identified as undisputable health system goals, the purpose of this study was to develop a reliable and valid instrument for investigating the attitudes of Greek physicians, nurses and administrative personnel towards job-related aspects, and the extent to which these motivate them to improve performance and increase productivity. 相似文献87.

Background
Breast cancer is the most commonly diagnosed cancer among women and a leading cause of death from cancer in women in Europe. Although breast cancer incidence is on the rise worldwide, breast cancer mortality over the past 25 years has been stable or decreasing in some countries and a fall in breast cancer mortality rates in most European countries in the 1990s was reported by several studies, in contrast, in Greece have not reported these favourable trends. In Greece, the age-standardised incidence and mortality rate for breast cancer per 100.000 in 2006 was 81,8 and 21,7 and although it is lower than most other countries in Europe, the fall in breast cancer mortality that observed has not been as great as in other European countries. There is no national strategy for screening in this country. This study reports on the use of mammography among middle-aged women in rural Crete and investigates barriers to mammography screening encountered by women and their primary care physicians. 相似文献88.

The production of inflammatory mediators by abdominal adipose tissue may link obesity and insulin resistance. We determined
the influence of systemic levels of interleukin-6 and C-reactive protein on insulin sensitivity after weight loss via Roux-en-Y
gastric bypass surgery. Severely obese individuals (n 5 15) were evaluated at baseline and at 6 months after surgery. Insulin
sensitivity was determined by frequently sampled intravenous glucose tolerance testing at the same time points. Visceral and
subcutaneous adipose tissue volumes were quantified by computed tomography. Interleukin-6 and C-reactive protein were measured
by enzyme-linked immunoassay in plasma and in adipose tissue biopsies. Correlation analysis was used to determine associations
between insulin sensitivity and other outcome variables. Significance was set at P < 0.05. Plasma interleukin-6 concentrations
were significantly correlated to the IL-6 content of subcutaneous adipose tissue (r = 0.71). At 6 months postsurgery, subcutaneous
and visceral adipose tissue volumes were significantly reduced (34.7% and 44.1%, respectively) and insulin sensitivity had
improved by 160.9%. Significant longitudinal correlations were found between insulin sensitivity and plasma C-reactive protein
(r = 20.61), but not plasma interleukin-6 at 6 months. These findings offer insights that link obesity and insulin resistance
via the activity of inflammatory mediators.

The evaluation of empirical data concerning private physician consultations in public hospitals in Greece suggests that privatisation of selected public services can increase patients' freedom of choice and also improve efficiency and quality of services, thus strengthening the supply side in a mixed healthcare system. The 2001 NHS health reform in Greece provides financial incentives to public hospital physicians to consult patients 'privately' at the outpatient clinics, while remaining restrained by certain provisions regarding fees. Competition between public and private hospitals is centrally regulated, and in this case cumulative data show success for the public sector. At the same time, patient satisfaction with the new arrangement measured in this study was very high. It could be argued that, under certain conditions, attracting private funds into a public health system constitutes an opportunity to reinforce the public provision of the system. 相似文献
