Diagnostic confusion between gastric carcinoma and gastric tuberculosis

Developing countries like developed ones need highly skilled medical personnel, referred to as 'specialists'. In the case of developing countries, the training of these specialists abroad is expensive to the sponsoring governments, imposes a lot of hardship on the doctors and, above all, the course-content of such training takes little or no cognizance of the environment in which these doctors would later practise. The developing countries also cannot afford the loss of years in valuable services which the training abroad entails. Attempts are now being made to train specialists wholly or partly at home, in some developing countries. The approach is still not much divorced from what obtains in Britain and North America, that is, one of being trained on the job, with the onus for self-education being placed on the prospective students. Such students in most developing countries of tropical Africa have little or no facilities for further education outside their places of work. It is proposed that purpose-designed postgraduate medical schools may provide a temporary solution to specialist training in developing countries of tropical Africa. Such schools would in addition provide highly skilled medical service as well as obviate the need and the expense for the setting up of government sponsored medical research and training institutes.     

Potential contribution of therapy to cancer mortality reduction

Reductions in cancer mortality may come about for a number of reasons, including improvements in treatment. The impact will vary from cancer to cancer. For some, expert curative surgery is crucial, whereas for others, the use of appropriate chemotherapy is a key factor. Examples of the latter, in which there are already discernible reductions in national cancer mortality data resulting from chemotherapy, include testicular cancer and Hodgkin's disease. For more common diseases, such as ovarian cancer, reductions also are being seen. For others, such as breast and colorectal cancer, the current more widespread use of adjuvant chemotherapy may lead to overall mortality reduction in the future. It should be recognized that chemotherapy should be given only by those experienced in its use, and that this facility should form part of a larger provision for health care in relation to cancer, ranging from public education to population screening and from better oncology training for clinicians to greater encouragement to participation in clinical trials. New drug development is clearly a priority, but further advances can be made in many countries already using available forms of chemotherapy if treatment facilities are organized appropriately.     

Pediatric nuclear oncology

Nuclear medicine plays an important and increasing role in the management of childhood malignancy. This is particularly true in the solid tumours of childhood. It is also helpful in the management of the complications of cancer treatment such as the infections which often accompany immune suppression in oncology patients. Scintigraphy is a complementary investigation to other radiological techniques and adds the functional dimension to anatomical investigations such as CT, MRI and ultrasound. Scintigraphy is used in the initial diagnosis, staging, assessment of tumour response to treatment, detection of recurrence and the diagnosis of complications. In selected malignancies radionuclides are also used in treatment. This review discusses the technical considerations relating to children and the specific techniques relating to pediatric oncology. Specific tumours and the various applications of radionuclides are discussed in particular lymphoma, primary bone tumours, soft tissue sarcomas, neuroblastoma, Iangerhan's cell histiocytosis, Wilms' tumour, brain tumours and leukemia. Uncommon tumours are also discussed and how radionuclides are useful in the investigation of various complications which occur in oncology patients.     

Information booklet for parents of children surviving cancer

With increasing survival rates in pediatric oncology, the medical and psychosocial costs of cure are becoming apparent for the child and his family. The focus of our concern is now how to prevent and to reduce these adverse late effects of cancer and its treatment. To reduce the late psychosocial consequences for the child and its family a booklet was written for parents. We decided to address parents because of the young age of many children when treatment is completed, the essential role of parents in alleviating late effects for the child and his siblings, and the possibility to discuss the whole range of psychosocial late effects: those for the patient, the siblings, and for the parents themselves. The booklet acknowledges the specific emotional problems in patients, parents, and siblings that results from surviving childhood cancer and provides information and support on how to deal with them. The booklet can enhance open communication with the health care team about late consequences. In this way the booklet supports the further integration of medical and psychosocial aftercare.     

Probability of particle and salbutamol deposition in the respiratory tract: comparison between MDI and Autohaler

QOL for children with chronic neurological diseases (CND) depends mainly on the supporting system of children's development and respite measurements of their families. For supporting children's development with CND and for alleviating the burden on the family members, various staffs are needed such as pediatricians, nurses, psychologists, OT, PT, home helpers, etc. Especially children with CND are living at home needs in-home services supplied by these supporting staffs. An in-home care service center is desirable to be established in their living area. According to the maternal and child health law and child welfare law, several measures have been adopted, but these services are not available for children with CND and their family, without registration as handicapped children. All these children should be treated because they have the same problems as physically or mentally handicapped children. The capability of the medical and social service supply has been influenced by recent decrease of the birth rate and improvement of the level in the maternal and child health. The number of facilities, such as pediatric clinics or nursing homes for physically handicapped children, is decreasing because of poor profit. These trends will be continued if appropriate measurements are not introduced. The final estimation of need and supply must be made at the local community level.     

2000 Peurifoy Lecture: Construction Practices in Developing Countries

Many contractors are expanding into global markets. Further, many owners procure construction services to build facilities in developing countries. The construction practices in these countries differ in important respects from practices in industrialized countries. This paper reviews some of the more significant differences in construction practices in developing countries. Five primary factors are discussed: cost of labor, cost of money, technology and methods, infrastructure, and role of the design professional. The hypothesis is presented that the main driving factors affecting construction practices are the cost of labor and the cost of money. These two factors place speed of construction as a secondary objective. Low labor costs lead to construction practices being labor-intensive. There is a distinct absence of construction equipment, especially small lifting devices used for material handling. Additionally, the lack of infrastructure means that many materials commonly purchased in the United States from a vendor are fabricated using on-site labor in developing countries.     

Behavioural hyperactivity in rats following postnatal exposure to sub-toxic doses of polychlorinated biphenyl congeners 153 and 126

Over the years, both government and the private sector have used a mix of regulatory controls and competitive market incentives to reduce the rate of spending and minimize excess capacity in health services. Despite these efforts, this study finds an oversupply of five medical technologies in Pennsylvania, which adds costs and raises concern over the quality of care provided by underused facilities. Moreover, as providers compete for network selection, many continue to expand their service capabilities. These findings emphasize the importance of ongoing assessment of the appropriate application, supply, and use of medical services.     

Cooperation of the family physician with the oncology center in the care of the children with tumors

With a cure rate of over 50% pediatric oncology contrasts with the adult oncology. The success is the result of a multimodal approach with surgery, radiotherapy and chemotherapy to almost all forms of childhood cancer as outlined in various national and international protocols. These are evaluated permanently concerning efficacy and toxicity at one organisation (in Switzerland: the pediatric section of the "Schweizerische Arbeitsgruppe für klinische Krebsforschung"). For the care of the children with malignancy however a specialist physician team at a tumor center is not enough. Without the cooperation of the family doctors of the area proper referral of the patients and long term treatment can not be realized. Good information and adequate teaching appears to be necessary to give these patients optimal care.     

Hospices: Perspectives on the public policy debate.

The public policy debate on hospice care centers on the appropriate mix of medical and supportive services for terminal cancer patients and how such services should be paid for within existing insurance programs. Past decisions to change health care reimbursement that are applicable to the hospice debate are reviewed, the benefits and costs of hospice care are examined, and the role of research in the formulation of social policy is discussed.

Magnetic resonance imaging relaxation times and gadolinium-DTPA relaxivity values in human cerebrospinal fluid

The purpose of this qualitative phenomenological study was to explore the lived-experience of childhood cancer survivors with regard to their patterns of interaction with family and the environment using Newman's theory of Health as Expanding Consciousness, which proposes that experiencing a devastating event promotes an expanded consciousness. The sample consisted of five young adults, ages 23 to 26 years, who had experienced childhood cancer and now are considered to be cured of their initial cancer. A hermeneutic dialectic approach was used, with each subject being asked to respond to one open-ended question, "What are the most meaningful events in your life?" The interviews were analyzed for evidence of expanded consciousness, changing relatedness, and other universal themes. Individual patterns emerged and themes were identified that supported Newman's theory, such as optimism and hope, stronger bonds to family and friends, increased capacity for empathy, a desire to help others, and deeper feelings for the value of life. The intensely personal and professional relationship that develops between pediatric oncology nurses and their patients can only be strengthened by the knowledge that these patients generally grew up to be caring and empathetic individuals, perhaps as a result of the nurses' loving care for them. This research also provided support for Newman's theory as a sound paradigm for nursing practice.     

Mental health: A shared concern of the international community.

Describes socioeconomic aspects affecting mental health in the world, such as the massive growth of cities, migrations of people, and the shrinking of the family unit in developed countries. International comparisons that examine differences and similarities between developing and industrialized countries are discussed. The needs of children and the elderly are discussed, and some examples of service delivery to these groups include improving daycare facilities, ensuring that schools foster psychosocial development, finding new roles for the elderly, and preventive and curative health services. Mental health services in Canada are highlighted, and some suggestions are proposed regarding areas of contribution of Canadian psychologists.

The home health aide as a member of the home healthcare team

Individuals of all ages are discharged from acute-care facilities with a variety of medical and nursing diagnoses. Many of these individuals require home health aides services in addition to their skilled care. In the changing healthcare environment of the 1990s, home healthcare professionals are being challenged to provide effective, skilled care that is the most cost-effective and appropriate for patients. It is important that all professional home healthcare personnel work as a team with home health aides to accomplish these goals. The home health aide is an important member of the home care team.     

Presence of activated B-1 cells in chronic inflamed gingival tissue

The oncology nurse's role in breast cancer management is enhanced by knowledge of the patient's perceptions of risks. This case study elucidates the process by which perceived risks of breast cancer are embedded in sequences of biographic experiences including childhood sexual abuse, childhood injuries, and an abusive marriage. The case study shows that risk perceptions and subsequent delayed breast cancer detection is related to (a) a belief that breast cancer results from "bad luck, or fate"; (b) lack of cancer-related symptoms; (c) belief that a higher power determines ill health; (d) reluctance to turn to others for help while in an abusive marriage; (e) family history of cancer invulnerability since generations of family members died of diabetes, heart disease, and pregnancy-related illnesses; and (f) fear of gynecologic exams resulting from childhood sexual abuse. Furthermore, nonapplicability of traditional breast cancer risk factors such as heredity, age older than 30 years at first full-term pregnancy, early menarche, and late menopause prohibit an accurate assessment of self-risk. This case study suggests that breast cancer risk perception often differs from that of biomedical factors, and that an understanding of risk judgments is essential for appropriate therapeutic responses.     

Management service organizations: effective strategy to assume and manage full risk agreements?

A management services organization (MSO) has emerged as one structure to manage professional and hospital risk agreements. Health plans and direct payers are transferring traditional functions to medical groups and health systems under these agreements. How does a hospital and affiliated medical group develop a strategy to assume, manage, and mutually benefit from these agreements? When do market forces dictate whether an MSO is the most appropriate organizational model to utilize? The development of an MSO can offer an effective organizational strategy to capture capitated contracts and assume responsibility for population-based medical services. This article explores the features of such an organization, areas for potential collaboration between the medical group and hospital, as well as the impact on patient care.     

Malignant keratoma

INTRODUCTION: Birth of an Harlequin fetus in an African maternity ward is an exceptional event. There is no question as to the diagnosis, but no treatment is available. CASE REPORT: A female infant was delivered with typical lesions of malignant keratoma. Death occurred 20 hours after birth. DISCUSSION: In countries with adequate intensive care facilities (hydration, acitretine), such infants may occasionally survive with the risk of developing major lamellar ichthyosis which remains a handicap for the rest of life. In Burkina-Faso, such therapeutic facilities are lacking as are means of antenatal diagnosis. The ethical question as to whether or not to attempt survival measures is quite different under these conditions.     

Health sector reform: lessons from China

As a result of China's transition to a socialist market economy, its rural health services have undergone many of the changes commonly associated with health sector reform. These have included a decreased reliance on state funding, decentralisation of public health services, increased autonomy of health facilities, increased freedom of movement of health workers, and decreased political control. These changes have been associated with growing inequality in access to health services, increases in the cost of medical care, and the deterioration of preventive programmes in some poor areas. This paper argues that the government's strategy for addressing these problems has overemphasised the identification of new sources of revenue and has paid inadequate attention to factors that influence provider behaviour. The strategy also does not address contextual issues such as public sector employment practices and systems of local government finance. Other countries can learn from China's experience by taking a systematic approach to the formulation and implementation of strategies for health sector reform.     

What is proper cancer care in the era of managed care?

Managed care and proper cancer care need not be mutually exclusive entities. Managed-care organizations (MCOs) that are committed to patients and society should have the following characteristics: accountability for results, cost containment, measurement of outcomes, health promotion and disease prevention programs, resource consumption management, emphasis on primary care, and continuous quality improvement. Whether these commitments are upheld depends on when and with whom the MCO contracts to provide care and which medical and quality assurance protocols it follows. If proper cancer care is to become a reality in the managed-care era, the oncology community must take a proactive stance. Oncologists must provide the market with an appropriate, efficient disease management plan for cancer. In concert with MCOs, the oncology community must define and, through partnerships, promote the seamless integration of proper cancer care. Patients and advocates should insist that MCOs' quest for efficiency allows for flexibility to address individual patients' circumstances.     

Advances and challenges for the expanded programme on immunization

Over 3 million deaths from measles, neonatal tetanus and pertussis are prevented by vaccination each year. In the Americas, poliomyelitis has been eliminated, and measles is close to elimination. Globally, reported poliomyelitis incidence has declined by over 80% since 1988. Strategies have evolved from strengthening routine childhood immunization services, to establishing disease surveillance and defining specific activities for disease control and elimination. Efforts to ensure the supply and quality of vaccines are underway. New vaccines against major pathogens will be licensed soon. Some of these will be used for groups other than mothers and infants, requiring re-definition of the 'EPI target groups'. Despite global successes, in 1995, six of the world's most populous developing countries reported coverage levels below 70% and coverage is below 50% in several African countries. Immunization programmes will need to be tailored to the level of economic and health systems development of a country. Industrialized countries must offer sustained support to expand immunization programmes in ways that strengthen health systems in developing countries.     

Cancer early-detection services in community health centers for the underserved. A randomized controlled trial

BACKGROUND: Achieving cancer early-detection goals remains a challenge, especially among low-income and minority populations. DESIGN/SETTING: A randomized trial based in 62 community health centers for the underserved in New York, New Jersey, and western Connecticut. Family physicians were on staff at most of the centers. INTERVENTION: Workshops, materials, and ongoing advice for center leaders promoted implementation of a preventive services office system to identify patients in need of services at each visit through use of medical record flow sheets, other tools, and staff involvement. EVALUATION END POINTS: The proportion of randomly selected patients by center who were up to date for indicated services at baseline (n = 2645) and follow-up (n = 2864) record review. RESULTS: Only 1 service (breast self-examination advice) increased more in intervention centers. Seven of 8 target services increased significantly for the 62 centers overall. During the study, the medical director changed in 26 centers (42%). Keeping the same medical director at intervention centers was associated with improvements in services. CONCLUSIONS: Cancer early-detection services are improving in community health centers, but the intervention had only a small impact, as determined by record review. To have an impact, the intervention required that there be no change in medical director. The relationship of changes in the practice environment to services delivered is complex and deserves more study.     

Sustaining leprosy services in the changing context of health sector reform

National leprosy control programmes currently face a number of changes to the environment within which they operate. This paper examines the issues arising from these. It focuses, in particular, on those arising from changes in the structure of the health sector as a result of policies of health sector reform which are being considered or adopted in many developing countries. These include decentralization, financing strategies, greater role for the private and NGO sectors and the integration of vertical programmes. The paper is structured around a number of key steps in the development of a strategy for sustainability of appropriate leprosy services. These are the assessment of the epidemiological, social and health services context, development of programme objectives, planning of human and financial resources, development of the strategy, mapping the roles of potential actors, development of regulatory and incentive mechanism, action planning and managing change and, finally, re-evaluation of the programme objectives and service delivery organization. The paper stresses the importance of process in developing ownership of a strategy. It concludes with a set of key questions which it suggests need to be addressed by leprosy programme managers in the development of a proactive response to the changes.
