Cervical lymph nodes are a common site of metastases for malignant tumors, most commonly developed from head and neck primary tumors. But, they can also be secondary to distant primary tumors.We report the case of two patients treated in our Otorhinolaryngology and Head and Neck department for chronic supraclavicular lymphadenopathies, for whom further investigations showed lymph node metastasis originating from distant tumors.Thus, careful clinical examination, imaging tools, and if possible pathological analysis are necessary to establish an early diagnosis for adequate treatment.  相似文献

This paper explores the potential contribution of timebanking, an innovative volunteering scheme, to the co-production of preventive social care with adults in England. Interest in volunteering in social care has increased as one proposed solution to the international crisis of a rising demand for services in juxtaposition with decreased resources. Volunteering has been particularly promoted in preventive services that prevent or delay care needs arising. Despite sustained interest in volunteering and co-production in social care, little is known about how theory translates into practice. Reporting implementation data from a Realistic Evaluation of six case studies in England, this paper explores one volunteering scheme, timebanking. The research explores how timebanks were working, what contribution they can make to adult social care, and whether they are an example of co-production. Data collected included interviews, focus groups or open question responses on surveys from 84 timebank members, and semi-structured interviews with 13 timebank staff. Each timebank was visited at least twice, and all timebank activity was analysed for a period of 12 months. Data were triangulated to improve reliability. The research found that in practice, timebanks were not working as described in theory, there were small numbers of person-to-person exchanges and some timebanks had abandoned this exchange model. Timebanks faced significant implementation challenges including managing risk and safeguarding and the associated bureaucracy, a paternalistic professional culture and the complexity of the timebank mechanism which required adequate resources. Lessons for timebanks are identified, as well as transferable lessons about co-production and volunteering in social care if such schemes are to be successful in the future.  相似文献

Genetically-based diseases with a late onset, such as BRCA1-dependent breast cancer or Huntington's disease, can be predicted by the screening of relevant mutations in members of high-risk families. Genetic screening is characterized by a conflict between respect for autonomy – e.g., the right not to know – and responsibility toward future generations (the duty to know for the sake of one's descendants). Other ethical conflicts are related to uncertainty as to benefits deriving from screening for mutations, since for most conditions no clearly effective therapeutical strategy has as yet been defined. In addition to monogenic high-penetrance conditions, polygenic low-penetrance susceptibility is attracting increasing attention, in particular with respect to environmental-genetic interactions (metabolic polymorphisms). A simple approach to genetic screening would be to weigh the benefits and costs of genetic screening against those of primary prevention, and a superficial conclusion might be that genetic screening is less expensive and, overall, more practicable than restriction of toxic exposures or other known risk factors for the disease. Economic advantage notwithstanding, however, giving precedence to screening over primary prevention would be unacceptable. A serious hazard of genetic screening is the implicit limitation of research efforts aimed at primary prevention, and a serious drawback is its potential application for selection of non-susceptible employees. The principle of equity is easily violated by genetic screening of workers in view of the fact that genetically-based metabolic polymorphisms are distributed unevenly among different ethnic groups.  相似文献

We want to report on our experiences with the percutaneous trephination using a 2.35 mm round dental drill with serrated saws around it, a Rosenbohrer. It is a methodically similar activity as described by J. Zentner [11].From 1981 to 1992 519 patients were treated and 546 trephinations were performed.At the beginning this treatment was only used in connection with intracerebral bleedings and biopsies.In a considerable short time the indication could be extended to the subdural hematoma, tumor cyst, obstructive hydrocephalus as well as to the abscess and the subdural epyema.The rate of infection was 1.28% and the risk of bleeding 0.36%.In our opinion the advantages of this small electrical trephination are the easy handling, the universal use and mobility and the avoidable risk of anesthesia as well as the sterilisation at the same time and the stopping of blood, caused by the contact surface friction.  相似文献

This paper presents a typology and transactional model of how close relatives cope with excessive drinking, drug-taking or gambling in the family. These are illustrated with four examples taken from a series of research projects in which relatives have been interviewed to understand better how they react and respond. Such information is the groundwork for a World Health Organization initiative to help primary health care workers respond to the needs of relatives. The philosophy behind this initiative, and the steps that primary health care workers might take, are outlined. It is proposed that such workers can help close relatives to find the best coping methods in their circumstances, and that this approach might constitute an important, and hitherto neglected, form of secondary prevention.  相似文献

A concise overview of current knowledge on the aetiology ofcongenital heart disease is provided. At present, only 10 to20% of the cases occurring in neonates can be attributed toknown risk factors. Recurrence within relatives, chromosomalanomalies, genetic disorders, maternal diseases and teratogenexposure are addressed briefly; contemporary research modelsand methods, e.g. embryology and genetics and molecular biology,are referred to. A major innovation has been the introductionof the concept of common pathogenetic pathways. Thus, differentteratogenic factors or risk-factors may affect normal developmentat an identical stage and cause similar malformations. Also,the importance of timing of an event is stressed. If the timeframe of exposure does not coincide with embryogenesis any teratogeniceffect may be missed. Large-scale epidemiological studies on fetuses and neonateswith congenital heart disease are introduced as a third modeof research on the aetiology, although this approach is notused efficiently at present; cases of intra-uterine death canbe considered a valuable source of information that needs furtherattention. Combined, the above three lines of research may proveproductive, but the design of a comprehensive research projectwould need to be handled carefully. Possibilities for preventionof the occurrence of cardiovascular malformations are reported.Through lack of knowledge of causality, at present, only secondaryprevention may be possible and hence deserves attention. However,there appears to be no provision for thorough pre-natal screeningtests for congenital heart disease in an unselected population.  相似文献

The health of a population is related to more than the volume and quality of health services available. Ischaemic heart diseases and cancers are the main causes of death for adults in most developed countries. Partly, these diseases are related to diet and other life style variables. The purpose of this article is to discuss some prevention possibilities related to health practices. Empirical data were collected by means of a questionnaire on health status and 'life style' among long-standing members of a Swedish popular movement for physical culture. The principal question was what could be learned for health planning and management. Genetic factors have lately come more in focus as an explanation of untimely death and disease while, for example, life style has been de-emphasized. There is a risk, thereby, that a purchaser-provider approach, where short-sighted returns are in focus, will give too low a priority to health promotion.  相似文献

The National Campaign Against Drug Abuse (NCADA) was established in April 1985. Aiming to provide a national framework to minimize the harmful consequences of drug use, the original 3-year programme was extended to 1997. A key figure in the NCADA, Dr Neal Blewett, was interviewed to gain his perspective on the development and implementation of the Campaign over its first 10 years.  相似文献

Summary The use of the conventional combination oral contraceptives (containing ethinyl-estradiol and a progestin) is associated with reduced risk of ovarian and endometrial cancer. However, prolonged use of these pills before first term pregnancy apparently increases the risk of pre menopausal breast cancer. We propose that the pineal gland hormone melatonin, combined with a progestin, as a new and novel oral contraceptive combination might prevent breast cancer in long term users. This hypothesis is based on the assumption that women have a propensity to develop breast cancer which correlates with number of ovulatory cycles over their lifetime. In evolution, the phylogenetic point at which women became sensitive to breast cancer evolved at a transfer point of the mechanism of ovulation from seasonal ovulation, which is still common in many mammalian species, to the current human pattern of continuous ovulatory cycles. We suggest that melatonin/ovariansteroid contraceptive will restore the lost mechanism of endogenous anovulation, and thus, by preventing continuous epithelial breast cell proliferation, will reduce the risk of breast cancer in long-term users.  相似文献
