The inflammatory reaction brings in phagocytic cells to the damaged area to clear cellular debris and to set the stage for wound repair (Figure 21 100mg vermox with amex hiv infection breast milk. The process not only brings fluid and cells into the site to destroy the pathogen and remove it and debris from the site discount vermox 100 mg line hiv transmission statistics female to male, but also helps to isolate the site, limiting the spread of the pathogen. If the cause of the inflammation is not resolved, however, it can lead to chronic inflammation, which is associated with major tissue destruction and fibrosis. It can be caused by foreign bodies, persistent pathogens, and autoimmune diseases such as rheumatoid arthritis. The released contents of injured cells stimulate the release of mast cell granules and their potent inflammatory mediators such as histamine, leukotrienes, and prostaglandins. Histamine increases the diameter of local blood vessels (vasodilation), causing an increase in blood flow. Histamine also increases the permeability of local capillaries, causing plasma to leak out and form interstitial fluid. Additionally, injured cells, phagocytes, and basophils are sources of inflammatory mediators, including prostaglandins and leukotrienes. Prostaglandins cause vasodilation by relaxing vascular smooth muscle and are a major cause of the pain associated with inflammation. Nonsteroidal anti-inflammatory drugs such as aspirin and ibuprofen relieve pain by inhibiting prostaglandin production. Many inflammatory mediators such as histamine are vasodilators that increase the diameters of local capillaries. At the same time, inflammatory mediators increase the permeability of the local vasculature, causing leakage of fluid into the interstitial space, resulting in the swelling, or edema, associated with inflammation. Leukotrienes are particularly good at attracting neutrophils from the blood to the site of infection by chemotaxis. Following an early neutrophil infiltrate stimulated by macrophage cytokines, more macrophages are recruited to clean up the debris left over at the site. When local infections are severe, neutrophils are attracted to the sites of infections in large numbers, and as they phagocytose the pathogens and subsequently die, their 996 Chapter 21 | The Lymphatic and Immune System accumulated cellular remains are visible as pus at the infection site. Not only are the pathogens killed and debris removed, but the increase in vascular permeability encourages the entry of clotting factors, the first step towards wound repair. Inflammation also facilitates the transport of antigen to lymph nodes by dendritic cells for the development of the adaptive immune response. However, they slow pathogen growth and allow time for the adaptive immune response to strengthen and either control or eliminate the pathogen. The innate immune system also sends signals to the cells of the adaptive immune system, guiding them in how to attack the pathogen. The Benefits of the Adaptive Immune Response The specificity of the adaptive immune response—its ability to specifically recognize and make a response against a wide variety of pathogens—is its great strength. Antigens, the small chemical groups often associated with pathogens, are recognized by receptors on the surface of B and T lymphocytes. The adaptive immune response to these antigens is so versatile that it can respond to nearly any pathogen. This increase in specificity comes because the adaptive immune 11 response has a unique way to develop as many as 10 , or 100 trillion, different receptors to recognize nearly every conceivable pathogen. The mechanism was finally worked out in the 1970s and 1980s using the new tools of molecular genetics Primary Disease and Immunological Memory The immune system’s first exposure to a pathogen is called a primary adaptive response. Symptoms of a first infection, called primary disease, are always relatively severe because it takes time for an initial adaptive immune response to a pathogen to become effective. Upon re-exposure to the same pathogen, a secondary adaptive immune response is generated, which is stronger and faster that the primary response. The secondary adaptive response often eliminates a pathogen before it can cause significant tissue damage or any symptoms. This secondary response is the basis of immunological memory, which protects us from getting diseases repeatedly from the same pathogen. By this mechanism, an individual’s exposure to pathogens early in life spares the person from these diseases later in life. Self Recognition A third important feature of the adaptive immune response is its ability to distinguish between self-antigens, those that are normally present in the body, and foreign antigens, those that might be on a potential pathogen. As T and B cells mature, there are mechanisms in place that prevent them from recognizing self-antigen, preventing a damaging immune response against the body. These mechanisms are not 100 percent effective, however, and their breakdown leads to autoimmune diseases, which will be discussed later in this chapter.

Mycotoxins: compounds or metabolites produced by a wide range of fungi that have toxic or other adverse effects on humans and animals Outbreak: an epidemic referring to a more localized situation. The term “food borne disease” is defined as a disease usually either infections or toxic in nature, caused by agents that enter the body through the ingestion of food (1). Food borne infections: are diseases whose etiologic agents are viable pathogenic organisms ingested with foods and that can establish infection. Food borne poisonings/ intoxications: diseases arising from the ingestion of toxins released by microorganisms, intoxications from poisonous plants or toxic animal tissues: or due to consumption of food contaminated by chemical poisons. New and re- emerging food born illnesses have resulted from recent changes in human demographics, international travel and commerce, microbial adaptations, economic development, technology and industry, eating behavior and land use. In the last couple of decades a number of diseases thought to be of unknown causes have been proven to result from food borne infections. In developing countries like Ethiopia in particular, the problem attains great proportions due to many reasons; basic among which are poverty, poor environmental sanitation and lack of public health awareness. In these modern day times in which food is usually not consumed immediately following and/or at the site of production, the risks of food-borne diseases are becoming increasingly important; the concern is obviously much more in areas where food storage and preparation safety measures are far from optimum. The extent of diagnostic evolution of food borne diseases can be based on history, clinical features, environmental assessment and laboratory investigations. Prevention and control of food–borne diseases, regardless of the specific cause, are based on the same principles: a. Specific modes of intervention vary from area to area depending on environmental, economic, political, technology and socio cultural factors. Place a drop of physiological saline in the center of the left half of the slide and place a drop of Dobell’s iodine solution in the center of the right half of the slide. With an applicator stick, pick up a small portion of the feces (about 2mg which is as much as the size of a match head) and put on the drop of saline. Mix the feces with the two different drops using the applicator stick to form a homogeneous suspension. Examine the saline preparations using the 10x objective for trophozoites (vegetative/motile forms) and cysts as well as oocyst of intestinal protozoa and for any ova or larva of helminthes.

This causes convulsions 100 mg vermox with visa hiv infection french kissing, coma proven 100mg vermox anti viral tissues kleenex, strokes, heart attacks, death of the baby and possibly death of the mother. Pre-eclampsia is treated by strict rest (which can be very effective), drugs to lower blood pressure and remove excess fluid, sedatives, and in severe cases, early delivery of the baby. An infusion of magnesium sulphate into a vein may be used while waiting for an emergency delivery if the mother is at high risk of fitting. The correct treatment of pre-eclampsia prevents eclampsia, and the prognosis is very good if detected early and treated correctly. Unfortunately there is no regime that will prevent pre- eclampsia or a recurrence, although low dose aspirin is being used experimentally for prevention in high risk mothers. To facilitate this expansion, the ligaments that normally hold the joints of the pelvis (and other parts of the body) together become slightly softer and more elastic which makes them more susceptible to strain. The joints of the spine are particularly at risk because the expanding uterus shifts the centre of balance and changes posture. Standing for any length of time is likely to impose unusual stresses on the back, and this strains the supporting ligaments and results in backache. Slight movements of the vertebrae, one on the other, can cause nerves to be pinched and result in pain such as sciatica. This nerve pinching is further aggravated by the retention of fluid in the whole body, which causes the nerves to be slightly swollen and therefore more easily pinched. The best way to reduce the likelihood of backache is not to gain weight excessively and to avoid all heavy lifting. At antenatal classes, physiotherapists show the correct way to lift, and teach exercises to help relieve the backache. The bleeding may be due to a slight separation of the placenta from the wall of the womb as it grows, and it almost certainly does not involve the baby directly. About 30% of all pregnant women suffer from some degree of bleeding during pregnancy, and some have quite severe bleeds without losing the baby. Other causes of bleeding in pregnancy include an ectopic pregnancy, significant separation of the placenta from the wall of the uterus (placental abruption), vaginal ulcers or erosions or hormonal imbalances. For example, if the last period started on 5 January 2003, she will be due to deliver on 12 October 2003. The most common types of pain are lower abdominal pain due to expansion of the uterus and its attached ligaments, backache and heartburn. Abdominal pain early in pregnancy may also signal significant complications, such as a miscarriage or an ectopic pregnancy. At this early stage, a false negative result is possible, and the tests are more reliable if carried out a couple of days after the missed period. A negative test may mean that the pregnancy is not far enough advanced to be detected, rather than that the woman is not pregnant, while a positive test is almost invariably correct. In a test carried out in a test tube, the mix of urine and chemicals will form a characteristic deposit; but more often the urine is added to one side of a small flat plastic container and as the urine moves across this it interacts with chemicals that will change colour if the test is positive. To ensure a reliable result, the test is generally carried out 2-7 days after the first missed period (ie. A pregnancy test can be carried out at home with a kit purchased from the chemist, but more reliable tests are performed by doctors using a sample of blood. Although pregnancy actually occurs about two weeks after a woman had her last period, for convenience doctors always date a pregnancy from the first day of that last menstrual period. The size, position, maturity, age and sometimes sex of the foetus can all be seen, and some of the internal organs of the baby, particularly the heart, can be checked. Abnormalities such as spina bifida (split spinal cord), hydrocephalus (excess fluid in the brain) and certain other congenital disorders can be identified. A routine scan may be performed between the sixteenth and eighteenth week of pregnancy when the foetus can easily be seen and transformed into an image. Babies under 500g have only a 40% chance of survival, under 1000g a 65% chance, and over 1500g a nearly 100% chance of survival.

Minor side effects like nausea and abdominal discomfort are rare usually well tolerated by the children. Children under one year old are not treated, as they are not exposed to infection. Accidental repeated treatment with several doses of de-worming drugs is not dangerous. Training someone on how to administer the drugs and the benefits of de-worming can be done in a few hours. Help to mobilise and support communities to produce fruit and vegetable gardens to improve access to vitamin A rich foods. Help to strengthen the national iodine deficiency control and prevention programme by monitoring use of iodised salt in your community twice a year (Study Session 5). Implementing advocacy and creating demand for universal consumption of iodised salt. It is a key factor for normal growth and in the fight against child illness and mortality in developing countries and therefore very important for public health. In addition, when zinc is provided as a supplement to children in lower-income countries, it reduces the frequency and severity of diarrhoea, pneumonia and possibly malaria. There is also some evidence that zinc supplementation of women during pregnancy may prevent adverse outcomes of pregnancy and contribute to increased infant weight gain and a reduced risk of infection. Zinc supplements have been shown to increase the growth and weight gain of stunted or underweight children. Moreover, studies have shown that children who receive zinc supplements have lower death rates. Approximately one third of the world’s population live in areas at high risk of zinc deficiency. The most vulnerable population groups are infants, young children, and pregnant and lactating women because of their additional requirements for this essential nutrient. Therefore, interventions to enhance the zinc intake of children in low-income countries are a useful strategy to reducing child mortality rates. Therefore, improving the zinc intake of women before and during pregnancy may help to reduce maternal mortality and benefit infant growth and survival. For young children, complementary feeding practices should be implemented with zinc-rich foods, such as animal source foods, and zinc-fortified complementary foods. Summary of Study Session 7 In Study Session 7 you have learned that: 1 If the vitamin A status in the body is very low, the immune system becomes weak and illness is more common and more severe, increasing under-five death rates. In adults, anaemia reduces work capacity and mental performance as well as tolerance to infections. Iron deficiency anaemia can also cause increased maternal mortality due to bleeding problems. In addition, zinc reduces the frequency and severity of diarrhoea, pneumonia, and possibly malaria. Write your answers in your Study Diary and discuss them with your Tutor at the next Study Support Meeting. You can check your answers with the Notes on the Self-Assessment Questions at the end of this Module. In this session you will be introduced to the issue of the overall shortage of food at the household level (household food insecurity). You will learn about its causes, consequences and prevention as well as nutrition emergency interventions. Coping strategies that may be adopted by households in response to constrained food supplies will be described, using local examples. Learning Outcomes for Study Session 8 When you have studied this session, you should be able to: 8.
