Some The first publicly funded midwife training program of these career satisfaction differences may be due to the began in 1911 (Rooks, 1997). In the White House Conference on Child Health and Protection that same year, it was noted that trained midwives surpass the Midwives record of physicians in normal deliveries (Rooks, History and Training. However, by the 1930s, midwives attended only from mid or with and wife or woman (Rooks, one eighth of U. In early times, seen as a standard model of care in other developed midwives were also known as wise women or countries (Rooks, 1997). This was and in the United Kingdom there is a growing use of unpopular with the church, because of the belief that midwifery-led, freestanding birth centers (Brodie, 2002). In this same report, Australian midwives reported Midwives, as women healers, were felt to have feeling dominated by medicine as the amount of med- special knowledge about the female mystery of birth. There During the Middle Ages, midwives were persecuted for was also concern raised about difficulties in keeping up using pagan birth rituals, and witch hunts of the 1400s skills in rural areas, due to lack of continuing education and 1500s killed many midwives. Men were often excluded from child- professional midwifery, and in the poorer areas, birth, and male barber-surgeons were called in only 7095% of births are attended by traditional midwives. Women were not permitted to practice almost all births occur in hospitals, due to national surgery (Ehrenreich & English, 1973). Bridget Lee Fuller was a British midwife brought and breast-feeding are important advantages. In the United States, midwives were minority women or immigrants who approximately 99% of midwives are women (Rooks, had trained in other countries (Reed & Roberts, 2000). Although midwifery and medicine differ, there health professions, pharmacy has one of the highest are some similarities as well (Rooks, 1997). With current growth has been described as a celebration of life rather than trends, the proportion of women in pharmacy may a medical procedure (Romero, 2002) and the midwife eventually exceed the proportion of women in the tends to focus on the woman and the experience of nursing field (Francke, 1987). Women in pharmacy practice pregnancy include efforts for smoking cessation and are rather novel in the United States and the first domestic violence prevention. Russia and the Philippines almost all pharmacists are Ideally, a pregnant woman is followed by the same women (Slining, 2000). There are concerns that this will lead decades, nurse-midwifery has expanded significantly to a shortage in the field, as women tend to work fewer (Reed & Roberts, 2000). This concern is licensing standards for midwives vary from state to state partially fueled by the recruitment pitch that a career in (Reed & Roberts, 2000; Rooks, 1997). However, national pharmacy can allow a woman to combine work with certification is necessary for the practice of nurse- having a family, and pharmacy can be practiced part midwifery in almost all states. In 2000, there were 45 programs accredited why women are interested in the field of pharmacy. These include the ability to use scientific knowledge Direct entry midwives (midwives not previously trained while being able to serve people. It has midwives may prescribe medications to patients been suggested that women pharmacists are superior in (Reed & Roberts, 2000). Native Americans have the highest Academic institutions have been slow to hire percentage of midwife births, followed by African female pharmacists and 50 years ago faculty were almost Americans and Hispanics, at much higher rates than exclusively male. It is thought that women are not hired as frequently wives continue to practice in underserved areas such as because women had not pursued Pharm. Finally, nurse-midwives salaries are much increases, the prevalence of male-dominated faculty is lower than that of obstetricians (Achterberg, 1990).

Evidence that a single replication fork proceeds from early to late replicating domains in the Igh locus in a non-B cell line. CpG sites are concentrated either in repetitive sequences or CpG islands in promoter regions. Dietary folate, vitamins B6 and B12, methionine and choline can critically affect the synthesis of AdoMet [3]. Moreover, methylation of CpG islands normally promotes a highly condensed heterochromatin structure, where active transcription does not occur. Methylation of CpG islands naturally takes place during X chromosome inactivation and imprinting, though the majority of CpG islands remain unmethylated during development and differentiation. Further investigation will be needed to elucidate the signicance of conversion to 5-hydroxymethylcytosine. Therefore, intensive screening of genes that are methylated in human cancers may be a strategy for identication of tumor-related genes that have potential as therapeutic targets. In some instances, genes can be silenced simultaneously due to a process of long-range epigenetic silencing, and the spreading of silencing seems to affect neighboring unmethylated genes through repressive chromatin [24]. Transcription of miR-10b is regulated by the transcription factor Twist, and the downstream targets of miR-10b include homeobox D10. Environmental factors inuence health, and epigenetic proles are known to be responses to environmental signals. Ductal adenocarcinomas of the pancreas frequently develop after chronic damage due to pancreatitis. At least a proportion of peripheral pancreatic ductal epithelia with an inam- 33 matory background may be at the precancerous stage. It has long been known that individual cancers each consist of heterogeneous cell populations. The recently proposed cancer stem cell hypothesis has emphasized that only certain subpopulations, known as cancer stem cells, cancer-initiating cells or tumor-propagating cells, have tumorigenic potential. These cancer-initiating cells are usually resistant to chemotherapy and radiotherapy, leading to treatment failure. Despite the existence of such subpopulations, the cancer stem cell hypothesis continues to generate controversy. Since the PcG complex targets similar sets of genes in embryonic stem cells and cancer cells, much effort should be focused on how epigenetic mechanisms participate in the generation of cancer-initiating cells [20,23]. Such subclassication may yield clues for clarication of distinct mechanisms of carcinogenesis in various organs, and identify possible target molecules for prevention and therapy in patients belonging to specic clusters. For example, progressive accumulation of genetic and epigenetic abnormalities has been best described in colon cancers. Together, the data show that colon cancers can be grouped into three molecularly distinct disease subclasses [95]. Multivariate analysis revealed that our clustering was a predictor of recurrence and was independent of histological grade, macroscopic conguration, vascular involvement or presence of renal vein tumor thrombi. Genetic and epigenetic events appear to accumulate in a complex manner during the developmental stage of individual tumors. Decoding of the results indicated that urine from prostate cancer patients contained shed cancer cells or debris. The promoter methylation pattern in urine generally matched that in the primary tumors. Gastrointestinal endoscopy followed by pathological diagnosis of biopsy specimens is useful for diagnosis of stomach cancers. Endoscopic biopsy is a topical procedure whereby only a small portion of the lesion is removed. Moreover, gastrointestinal endoscopy is neither comfortable nor risk-free for patients, and is associated with frequent morbidity.
Predators Larvivorous fish such as Cambusia affinis have been used for 225 controlling mosquito larvae for many years generic avodart 0.5 mg amex medicine ball chair. Among the more promising recent developments is the use of young Chinese catfish (Clarias fuscus) to control Ae proven 0.5mg avodart symptoms of flu. Personal protection Personal protection includes all measures taken at the individual or the household level to prevent biting by vectors buy generic avodart 0.5mg on line medicine 93 5298. Anklets impregnated with repellents significantly reduced biting rates of mosquitoes buy 0.5mg avodart medicine video. Bed netting has been used for centuries to give personal protection against biting insects. When impregnated with insecticides, the netting provides community protection as well; mosquitoes rest on the treated fabric and are killed. In numerous large-scale trials in various parts of the world, malaria transmission appears to have been reduced by the systematic use of nets impregnated with permethrin or deltamethrin. House improvements such as screening, insecticidal paints, and filling in cracks in the 226 walls could provide definitive measures against some house hold insects. Trapping Mechanical and other types of traps have been used to reduce populations of tsetse flies. Several designs have been developed, some of them incorporating chemical attractants and insecticides. In Uganda, an effective tsetse trap has been made from old tires and locally available plant materials. Light traps, installed in pig sites, have been tested for the control of Culex tritoeniorhynchus in Japan. Environmental management Changing the environment to prevent vector breeding or to minimize contact between vectors and people can be an effective control mechanism. Intermittent irrigation was used to prevent the development of 227 mosquito larvae in rice fields and layers of expanded polystyrene beads prevented Culex quinquefasciatus from laying their eggs in wet pit latrines. Much environmental management work can be done by community volunteers with guidance in the initial stages from vector-control specialists. The use of this method has given people a false sense of security, reinforced their belief that Ae. Nevertheless, examples of successful community participation include: setting tsetse traps; draining, filling, or clearing weeds from mosquito breeding sites; rearing larvivorous fish; source reduction of Ae. Vector-control campaigns should work closely with primary health-care programs to achieve greater effectiveness and sustainable results. Community volunteers may become victims of political struggles or professional rivalries if their work is not given proper recognition. The best chance of maintaining community support seems to lie in integrating vector control into the primary health-care system, which is now established in many countries. More research is also needed on how to coordinate vector control with work in agriculture, forest and water management, and on the role of migrant workers in disease ecology and control. Although local initiatives should be encouraged, each country will still need teams of professional vector-control workers, using well-established methods, to meet its obligations under international health regulations. Optimizing use, doses, and safety of control measures and balancing vector control with consideration for the environment is a challenge we must face. Future considerations must include such questions as whether an insecticide-free environment is possible, or desirable. All development projects should include ecological planning to prevent increases in vector-borne diseases. The role of the primary health-care system must be defined and inter-sectoral 230 cooperation obtained. In addition, there are novel controls which are specific to a particular kind of pest, for example behavioural or sterilization controls against some insects. The nature of the pest fundamentally affects the significance of different control mechanisms. In general, pathogens have a much more intimate relationship with the host than do insect pests. Cultural and mechanical controls- These have been the cornerstones of many pest control practices, particularly in arable agriculture throughout the world. They remain the single most widely used control method in both industrialized and developing countries, even though the use of many such controls has been eroded through the substitution of pesticides. In conclusion, much more attention must be paid to the whole range of cultural controls, especially as they have so often tended to be disregarded because their value has not been appreciated, or because it has seemed easier or more effective to replace them with pesticides. B Biological controls- The value of biological control is also demonstrated by the resurgence phenomena associated with the use of broad-spectrum insecticides, which kill not only the pest, but also its natural enemies. If the pest is one that re-establishes itself more quickly than its natural enemies, a single treatment of a crop with the pesticide will be followed by a more intensive attack, 232 requiring a further spray, and creating an even greater problem. Proper understanding of the management of indigenous natural enemies of pests is one area of research which could lead to far more environmentally desirable procedures for pest management. There is good evidence that competitors have a major impact on rust pathogens, and cultural controls often work effectively because of their influence on soil-borne pathogens. Retention and enhancement of natural biological controls against most pests must be a major factor in desirably safe and sustainable pest management practices. Chemical controls-The vast array of pesticides now available, firstly insecticides and then herbicides and fungicides, has transformed pest management. However, this has sometimes led to over-reaction: the actual and potential value of chemical pesticides must be recognized, both for food production and for disease control. Moreover, some emerging technologies such as those based on genetic engineering and the use of pathogens may have more serious disadvantages for man and the environment than many currently used synthetic pesticides. Certain insecticides must be seen as environmentally hazardous through their toxic effects on man and on various biological systems. Many of the worst have been phased out; however there are ironical situations in some countries, whereby some pesticides highly toxic to man are still being recommended, while relatively safe alternatives have been banned because they are harmful to natural enemies of pests. Such controls are fundamental to any pest management system, though it is disappointing that other kinds of control have so far made relatively little impact on the pest management scene. At present, we must therefore rely heavily on the four basic methods listed above, and on improvements in their integration. It has to be cheap in terms of cost, easily prepared for use, on-corrosive and non-odorous. However at present there is no such perfect insecticide that fulfills all the standards mentioned above. They are generally classified in to seven categories based on their chemical composition (formula). Inorganic insecticides These are one of the oldest group of chemicals employed to control insects, but with certain exceptions, they are not in a widespread use today.

Nymph The larval form of certain insects, usually resembling the adult form but smaller and lacking fully developed wings. Occupational Infectious diseases that are contracted through the course of a disease person performing his or her work. These contagious diseases are usually caused by virusesor bacteria, though in some occupations parasitic agents are important. Occupationally contracted contagious diseases are considered compensable through the workers compensation system, just like any other occupationally-caused disease. Occupational An event that occurs during the performance of job duties and exposure may place a worker at risk of infection.

Plague An infectious disease of animals and humans caused by a bacterium named Yersinia pestis. Polio A viral infection that occurs in the gastrointestinal tract with spread to lymph nodes and, possibly, the nervous system. Prevalence The number of existing cases of a particular disease present at a given time in a defined population. The prevalence is usually expressed as a proportion or a percentage of the population under study.

Similarly, rodents and snails are also potential reservoirs for a number of diseases besides their contribution economic to losses. These vector borne diseases, however, could have through the application of environmental modification methods. This lecture note contains 13 chapters where the general feature, life cycle, medical importance and appropriate prevention and control strategies are touched with some practical examples and review questions. In been prevented or controlled through the application of vector control methods, particularly other words, it will guide the reader to the subject matter of vector and rodent control by presenting general information first and then specific diseases transmitted by the vector and its control methods. A lecture note on vector and rodents control was prepared in 2002 by Ato Solomon Tassew for Diploma environmental health students by collecting the necessary information relevant to the course from existing books, journals, and lecture materials. Now by putting similar effort that material is reorganized and updated with the aim of making it a sufficient reference material for degree Environmental health science students. Comments of different instructors from department of Environmental health, Faculty of health sciences, Haramaya University were also incorporated which brought the material to its present status. Generally, Environmental health professionals have the responsibility to plan and apply appropriate vector control programs at community level to prevent diseases transmitted by arthropods, rodents and snails through organized community participation. It is based on the previous lecture note that this material with wider content is made. We are also grateful to all Carter Center-Ethiopia staffs, to staffs of Haramaya University, Faculty of health science especially Ato Tesfayie Gobena and Andualem Sitotaw who reviewed the material with great courage. We also extend our appreciations to Ato Yohannes Tesfaye (Defence unvesity college), Ato Ahmed Mohammed (Jimma University), Ato Tesfaye Tilaye (Gondar University) and Ato Alemayehu Woldecherkos ( Hawassa University) who have critically reviewed and contributed a lot to bring this lecture note in to this stage. Existing Problems of vectors The relation ships of early humans to insects were similar to those between insects and other primates and mammals. Insect parasites, fed on humans, annoyed them and transmitted diseases among them. In common with other mammals, humans have acquired host- specific parasites, for instance, the head and body louse. Insects also destroyed stored foods, shelters and articles made of wood, plant fibers and animal hides. In turn, primitive peoples, sometimes 1 as a regular part of their diet ate insects. Honeybees are native to the old world and stingless bees produce honey in the tropics of the new world.
