The substance need not necessarily be tumourspecific but can be used as a marker because it is secreted in much greater quantities by tumour cells. Paraproteins (monoclonal immunoglobulins) These markers are of value in the diagnosis and/or follow-up of the following tumours: 1. Bleomycin (ii) vinca alkaloids bind to tubulin and disrupt the mitotic spindle a. Intestinal ulceration inhibition of production of epithelial cells leading to loss of function and ulceration 3. X-rays are machine-generated electromagnetic radiations of zero mass and charge 2. They are produced by the nuclear reactions of high-energy electromagnetic radiation and the decay of radio-active elements, such as radium and uranium 4. Direct action One mode of action may be a direct ionisation of part of a molecule by the absorbed energy 2.

Haemopoietic syndrome (4-10 Gy) (i) Lymphopenia (ii) Granulocytopenia (iii) Thrombocytopenia Death may result from infection or haemorrhage 2. Gastrointestinal syndrome (10-15 Gy) (i) Villous atrophy (ii) Mucous depletion 170 Death is due to fluid and electrolyte imbalance, infection, or nutritional impairment 3. Cerebral syndrome (>100 Gy) Nerve cells are destroyed by either direct radiation injury or secondary to increased vascular permeability with oedema and pressure damage. Nausea and vomiting are followed by tremors and convulsions with death 1-2 days after exposure. If the patient survives the acute phase then there are a number of possible late effects: 1. Leukaemia, skin cancer, or cancer in other organs such as thyroid, bone, larynx, etc.

If a dedicated elevator is not available, waste should not be transported at the same time as clients/patients/residents, food serving carts or clean/sterile instruments/supplies/linen. Waste must be 2 transported by a certified waste hauler who provides a certificate of approval. In general, where the primary biomedical waste container is a sharps container or a rigid container with a nonremovable lid, additional packaging or containment of the waste is not necessary for off-site transportation. Where the primary container is a plastic bag, the bag shall be placed into a rigid, leak-proof outer container for 374 transportation off-site. For details on the classification, packaging, documentation and training requirements for shipping infectious substances, see ?

All infections that spread by direct contact can be transmitted via direct person-to-person contact through contaminated skin or clothes purchase cheap bystolic online zantac blood pressure medication. Conjunctivitis and trachoma can be transmitted through infected skin generic bystolic 5mg mastercard blood pressure number meanings, clothes buy cheap bystolic 2.5mg line blood pressure medication heart rate, or other contaminated material that came in contact with infectious eye discharges. Several other infections transmitted through direct contact affect the skin, and the pathogens can be spread simply through direct skin contact, including yaws, scabies, and tinea. Body lice, the vector of louse-borne typhus, louse-borne relapsing fever, and trench fever live on people’s unwashed clothes (61). Fleas, which transmit plague (73) and murine typhus fever prefer people with poor personal hygiene. Keeping body and clothes clean will reduce the transmission risk of all these infections. The disease groups linked to poor hygiene of body and clothes are shown in Table 5. Reduction in infections associated with improved water availability and personal hygiene Disease (group) Reduction in Remarks occurrence Diarrhoea 20% (26) increase water availability (handwashing) Infant diarrhoea 30% (32) wash hands with soap after defecation and before eating Roundworm 12-37% (26) increase water availability (handwashing) Trachoma 30% (26) increase water availability (washing of hands and face) (3) Yaws 70% (29) increase water availability (washing of body) Louse-borne typhus/ 40% (29) increase water availability (washing of clothes and body) relapsing fever 5. In practise, it will rarely be possible to provide this, and a compromise will have to be made which takes into account the local social, cultural, physical, financial, and environmental constraints. The amount of water that people need, or use, will depend on its availability and what it is used for. Factors that influence water use include the socio-economic status of the users, whether and how people have to pay for the water, whether water is easy to get, and whether water is used for special activities (e. Water is lost during distribution, and this will have to be taken into account when looking at how much water must be provided to a population. In the initial phase of an emergency internally displaced people and refugees will need a minimum of three to five litres per person per day to survive, and as soon as possible this will have to be increased to 15 to 20 l/p/d to allow for water for (21) personal hygiene. In a stable situation, the minimum amount of water available (68) to people should be 25 l/p/d. Water needs, demands, and losses People (in litres/person/day (l/p/d)) (21,68) Institutions (in l/p/d) (21,66,68) Minimum survival 3-5 Health centre, out-patients 5 Drinking and cooking needs 8-10 Health centre, in-patients 40-60 Minimum supply required 15-20 (without laundry) Cholera treatment centre 60 Therapeutic feeding centre 15-30 Livestock (in litres/animal/day) (21) School 25 Cattle 20-40 Donkeys, horses 10-40 Other (21) Sheep, goats 1-5 Irrigation 3-6 l/m2/day Water losses in supply systems Standpipe supply (in l/p/d) (68) In a medium to large distribution system in reason- Rural, village control 45 able condition: 15-25%.

Studies have shown that people will not really restrict their water use if collection times are less than three minutes, or a distance of about 100m in easy terrain with no waiting times. Interestingly, the amount of water collected if the collection time is between three and 30 minutes remains constant. This means that if it takes eight minutes to fetch water, the amount of water used will be more or less the same as if it took 20 minutes to collect it. The largest health benefit from an improved water supply will result if collection times are below three minutes.

The design of a more complex system will be more demanding order generic bystolic line blood pressure medication that doesn't cause cough, and if the reader is not familiar with these procedures the design should be left to a specialist purchase 5 mg bystolic with visa 04 heart attack m4a. Refuse cheap bystolic 5mg arteria anonima, soil, and the vegetation which accumulates in drainage channels will reduce the capacity of the system, and regular maintenance will be needed to keep it functional. Regular maintenance and inspection will also deal with collapse or other structural damage in the system. The responsibilities of all actors in maintenance and structural repairs must be addressed early in the planning phase. The problem of solid waste management should be addressed in the planning phase of the drainage system as poor management of refuse (e. Where the channels are not protected with a lining, erosion can be a problem if water flows at high speed or if the sides of the drains are too steep. If tools or other materials are required for maintenance, these must be available to those who need them. Where filling is not feasible, the vegetation along the sides of the water can be removed to make it less attractive to snails and mosquitoes, or the shoreline can be made steeper to control the vegetation. The best way to deal with potential breeding sites for Aedes mosquitoes depends on the situation: solid waste must be removed, water tanks and drums must be covered with a lid or mosquito-proof netting, gutters should be maintained, hollow construction blocks or bricks should be filled, containers that are needed (61) but not used should be turned upside down, and holes in trees must be filled. It will only be possible to control Aedes by teaching people to be very vigilant and attentive to the problem. This chapter looks at communicable disease in relation to solid waste, and presents some practical issues about managing refuse. Solid waste management up to neighbourhood level, including local health structures, is considered, but the management of wastes from industries, mining, or structures like large hospitals or abattoirs are more specialised, and will not be covered here. Poor solid waste management will result in an unpleasant and often unsafe (15) environment to live or work in. In urban areas refuse often ends up in drainage systems, creating drainage prob- lems (see Chapter 7). Pollution caused by poor management of waste can create serious environmental problems. For example, one litre of diesel can in theory make around 80,000m3 of (46) water undrinkable according to European standards. Those who handle the waste, and those who live or work where the waste accumulates, will therefore often be at risk from excreta-related infections. The specific health risks they will be exposed to will depends on their contact with the excreta (see Table 6. As drainage systems are frequently used for defecation, the solid waste that accumulates in the system is often contaminated, and is a health risk to those who (39) have to handle it.
