Myelin is the fatty substance that coats and protects these fibers cholesterol levels uk average purchase atorvastatin 20 mg with amex, similar to low cholesterol foods high protein buy genuine atorvastatin on line the way insulation shields electrical wires cholesterol levels how to lower buy atorvastatin 40 mg mastercard. In people with multiple sclerosis cholesterol medication tricor generic 10mg atorvastatin with mastercard, the immune system mistakenly destroys the cells that produce the myelin sheath cholesterol medication gout generic 5mg atorvastatin visa. As a result, myelin becomes inflamed and swollen and detaches from the nerve fibers. When nerve impulses reach a damaged area, some impulses are blocked or delayed from traveling to or from your brain. A number of researchers believe the disorder is related to a protein that mimics the myelin protein, which may be introduced into the body by a virus. Heredity: Multiple sclerosis is more common in people of Northern European descent. Researchers suspect that the tendency to develop multiple sclerosis is inherited, but the disease manifests only when environmental triggers are present. Geographical: Multiple sclerosis is more common in countries with temperate climates, including Europe, southern Canada, northern United States, and southeastern Australia. A period of disease activity (exacerbation) may be triggered by a viral infection, such as a cold or flu, or by changes in the immune system during the first six months following a pregnancy. The flare-ups typically appear suddenly, last a few weeks or months, and then gradually disappear. Primary progressive: People with this less common form of multiple sclerosis experience a gradual decline, without periods of remission. Sudden relapses may occur, superimposed upon the continuous deterioration that characterizes this type of multiple sclerosis. Diagnosis Medical History: Your doctor reviews your signs and symptoms and their pattern. Neurological examination: this examination systematically tests various parts of your nervous system, including your reflexes, muscle strength, muscle tone, and sensations of pain, heat, touch and vibration. Your doctor may also observe your gait, posture, coordination and balance, and ask questions to help determine the clarity of your thinking, judgment and memory. Spinal tap (lumbar puncture): In this procedure, a doctor or nurse removes a small sample of cerebrospinal fluid from within your spinal canal for laboratory analysis. This sample can show abnormalities associated with multiple sclerosis, such as abnormal levels of white blood cells or proteins. Evoked potential test: this test measures the electrical signals sent by your brain in response to stimuli. An evoked potential test may use visual stimuli or electrical stimuli, in which short electrical impulses are applied to your legs or arms. Treatment If your attacks are mild or infrequent, your doctor may advise a wait-and-see approach, with counseling and observation. Medications for multiple sclerosis treatment include: Beta interferons: Interferon beta-1b (Betaseron) and interferon beta-1a (Avonex, Rebif) are genetically engineered copies of proteins that occur naturally in your body. It works by blocking the attachment of immune cells to brain blood vessels a necessary step for immune cells to cross into the brain. Other medications: Mitoxantrone (Novantrone) is a chemotherapy drug used for many cancers. They include: Corticosteroids Doctors most often prescribe short courses of oral or intravenous corticosteroids to reduce inflammation in nerve tissue and to shorten the duration of flare-ups. Prolonged use of these medications may cause side effects, such as osteoporosis and high blood pressure (hypertension), and the benefit of long-term therapy in multiple sclerosis is not established. Muscle relaxants Medications to reduce fatigue To help combat fatigue, your doctor may prescribe an antidepressant medication. Other medications Many medications are used for the muscle stiffness, depression, pain and bladder control problems associated with multiple sclerosis. Non-medicine Treatments Physical and occupational therapy: A physical or occupational therapist can teach you strengthening exercises and show you how to use devices that can ease the performance of daily tasks. Therapists are usually supervised by doctors (physiatrists) who advise and coordinate the therapy that you might receive. Therapists can assist you in finding optimal mobility assistance devices such as canes, wheelchairs and motorized scooters. Counseling: Individual or group therapy may help you cope with multiple sclerosis and relieve emotional stress. This procedure involves removing some of your blood and mechanically separating the blood cells from the fluid (plasma). Your blood cells then are mixed with a replacement solution, typically albumin, or a synthetic fluid with properties like plasma. Replacing your plasma may dilute the activity of the destructive factors in your immune system, including antibodies that attack myelin, and help you to recover. Plasma exchange has no proven benefit beyond three months from the onset of the neurological symptoms. Lifestyle Get rest: Fatigue is a common symptom of multiple sclerosis, and getting your rest may make you feel less tired. If you live in a hot and humid area, consider having air conditioning in your home. Eat a well-balanced diet * * * * * Pink Eye Pink eye (conjunctivitis) is an inflammation or infection that lines your eyelid and part of your eyeball. The whites of your eyes may begin to have a pink discoloration, and you may not see as well as you did before. Symptoms Redness in one or both eyes Itchiness in one or both eyes Blurred vision Sensitivity to light A rough feeling in one or both eyes A discharge in one or both eyes that forms a crust during the night Tearing Causes Viruses Bacteria Allergies A chemical splash in the eye A foreign object in the eye Viruses cause most cases of pink eye. Bacterial conjunctivitis often produces a thicker, yellow-green discharge and may be associated with a respiratory infection or with a sore throat. Treatment Your doctor may prescribe antibiotic eye drops if the infection is bacterial, and the infection should clear within several days of starting treatment. Antibiotic eye ointment, in place of eye drops, is sometimes prescribed for treating bacterial pink eye in children. An ointment is often easier to administer to an infant or young child than are eye drops. Make sure that you use the medication for the entire time your doctor prescribes it, to prevent repetition of the infection. Like a common cold, you can use an over-the-counter remedy to relieve some symptoms, but the virus just has to run its course. These may include: Antihistamines Decongestants Mast cell stabilizers Steroids Anti-inflammatory drops Prevention Practicing good hygiene is the best way to control the spread of pink eye. As it swells in size, the sty may make it hard for you to see well because you cannot open your eye completely. Diagnosis If the symptoms of a sty continue or if you have had several infections, your doctor may want to rule out other possible causes. If your doctor confirms you have a sty, he or she can prescribe treatment or recommend ways to relieve your pain or discomfort. Treatment If your doctor confirms that you have a sty, he or she may prescribe a topical antibiotic cream to apply to your eyelid. To treat a pus-filled sty that will not burst on its own, your doctor or ophthalmologist may choose to cut and drain the sty to relieve pain and pressure. Usually you will not need oral antibiotics unless you have an infection of your eyelid. It occurs when tissue in the macula, the part of your retina that is in charge of your central vision, deteriorates. Degeneration of the macula causes blurred central vision or a blind spot in the center of your visual field. Macular degeneration is the main cause of severe vision loss in people age 60 and older. The damage caused by macular degeneration cannot be reversed, but early detection and treatment may help reduce the degree of vision loss. Macular degeneration occurs in two Types: Dry macular degeneration Most people with macular degeneration have the dry form. The dry form may initially affect only one eye but, in most cases, both eyes eventually become involved. The normally uniform reddish color of the macula takes on a mottled appearance because of the patchy loss of pigment. Drusen, which look like yellow dots, are fatty-like deposits that appear under the light sensing cells in the retina. Many people who have received a diagnosis of early-stage dry macular degeneration may not be bothered with symptoms, such as blurred eyesight, unless they live to a very old age. However, as the drusen and mottled pigmentation continue to develop, your vision may deteriorate. This affects the overlying cones and rods and may result in complete loss of your central vision. Wet macular degeneration the wet form accounts for about 15 percent of all cases, but it is responsible for most of the severe vision loss that people with macular degeneration experience. If you develop wet macular degeneration in one eye, your odds of getting it in the other eye increase greatly. Wet macular degeneration develops when new blood vessels grow from the choroid underneath the macular portion of the retina. These vessels leak fluid or blood, which is why it is called wet macular degeneration. Eyes with the wet form of macular degeneration usually show signs of the dry form, that is, drusen and mottled pigmentation of the retina. In addition, what should be straight lines in your sight become wavy or crooked, and blank spots appear in your field of vision. Much like the dry form of macular degeneration, a breakdown in the waste removal system may be what is causing the abnormal growth of blood vessels. When the waste from the cones and rods is not disposed of and begins to accumulate, sufficient flow of nutrients to the macula is interrupted. The abnormal growth of blood vessels may be a response to this interruption in the flow of nutrients. The mechanism that triggers the development of new blood vessels is unclear, and it remains the subject of scientific study. Whatever the cause of the abnormal growth, the result is a disruption in the nutrition of the macula, and without enough nutrients, healthy tissue in the macula begins to deteriorate. With the wet form of macular degeneration, sight loss is usually rapid and severe, often deteriorating to 20/200 vision or worse, which is considered legally blind. This means that what someone with normal vision can see from 200 feet away, a person with 20/200 vision can see only from 20 feet away. The fluid collects under the retinal pigment epithelium, causing what looks like a blister or a bump under the macula. This kind of macular degeneration causes similar symptoms to typical wet macular degeneration, but your vision can remain relatively stable for many months or even years before it deteriorates. Eventually, however, this form of macular degeneration usually progresses to the more common wet form of macular degeneration that includes newly growing abnormal blood vessels. The symptoms of the disease may differ, depending on which of the two Types: of macular degeneration you have: dry or wet.

Bacteria: Aeromonas hydrophila, enteroadherent during epidemics; Escherichia coli, enteroinvasive Escherichia coli, Page 60 Module 3 enterohaemorrhagic Escherichia coli, Plesiomonas during the warm season, whereas viral diarrhoeas, shigelloides, Vibrio cholerae non-O group 1, particularly disease caused by rotavirus, peak during Vibrio parahaemolyticus, Yersinia enterocolitica the winter. Protozoa: Giardia lamblia, Entamoeba tends to occur throughout the year, increasing in histolytica, Isospora belli. The incidence of persistent diarrhoea of healthy children under 3 years of age, making it follows the same seasonal pattern as that of acute difficult to know whether a pathogen isolated watery diarrhoea. This is especially true for Giardia lamblia, Most enteric infections are asymptomatic, cysts of which are found nearly as often in healthy especially in those over 2 years of age owing to the children as in those with diarrhoea; it is also true development of active immunity. On the other hand, which time stools contain infectious viruses, Shigella and rotavirus are rarely identified in healthy bacteria, or protozoal cysts. Persons with children; their presence in a child with diarrhoea asymptomatic infections play an important role in strongly indicates that they are the cause of the the spread of many enteric pathogens, especially illness. Intermediate areas include the southern European countries (eastern and western) and the Now carry out Learning Activity 2. Manifestations There are three types of diarrhoea: Page 61 Distinct seasonal patterns of diarrhoea occur in. Most enteric pathogens intestinal mucosa stimulate at least partial immunity against repeated. Other complications may occur, for example, infection or illness, which helps to explain the haemolytic uraemic syndrome, which may cause declining incidence of disease in older children and renal failure adults. The most important cause of acute dysentery is increasingly susceptible with advancing years if they Shigella; other causes are C. The diagnosis of infective diarrhoea is dependent upon the identification of the causative pathogen Persistent diarrhoea from the faeces by culture, antigen detection or by. Begins acutely, but is of an unusually long light microscopy (in the case of parasites). In most aetiological diagnosis, although clinical features can cases the information gained by spending a few act as a rough guide. The treatment of diarrhoea minutes asking for details of the illness, and must therefore be based on the major features of observing and examining the child for specific signs the disease and an understanding of the underlying (dehydration or undernutrition) is sufficient to pathogenetic mechanisms, as described earlier. The top part of the chart shows how to assess Signs that are most valuable in assessing patients for dehydration and how to assess and dehydration, termed key signs, are marked with manage other important problems. Two or more circled features described in these figures are the features signs in one column, including at least one key that are most important and can be most reliably sign, means that the patient falls in that category assessed by health workers at all levels. If signs are noted in more than one column, as often Assessing the child for dehydration occurs, the category of dehydration is the one Children should first be evaluated for dehydration farthest to the right (among columns A, B, and C) and then for other problems associated with in which two items, including at least one key sign, diarrhoea. However, when a child is severely dehydrated, taking a complete history and Column C: Severe dehydration doing a thorough examination must be deferred Look first at column C. A circled in that column, including at least one key stuporous child, with severe dehydration requires sign, the patient has severe dehydration. Children with severe dehydration have a fluid the detection of dehydration is based entirely on deficit equalling more than 10% of their body clinical signs. They are usually lethargic, stuporous or identify children with diarrhoea who are at even comatose. The eyes are deeply sunken and increased risk of becoming dehydrated, for without tears; the mouth and tongue are very dry, example, those children who are vomiting, have a and breathing is rapid and deep. Children who are fever, or have passed six or more diarrhoeal stools awake are very thirsty; however, when there is in the past 24 hours. Children who fluids or water have been restricted or could not are unconscious are unable to drink. When Page 64 Module 3 there is hypovolaemic shock, the systolic blood Column A: No signs of dehydration pressure taken in the arm is low or undetectable, If neither severe dehydration nor some dehydration the arms and legs are cool and moist, and the nail is present, the child has no signs of dehydration. Children with diarrhoea but no signs of dehydration usually have a fluid deficit, but it Severe dehydration requires urgent treatment, usually equals less than 5% of their weight. Children with no If severe dehydration is not present, look next at signs of dehydration can be treated at home, column B. If the signs in column C are not sufficient to diagnose Weigh the child severe dehydration, they should be counted as Children who are found to have some dehydration belonging to column B. This category includes both mild and moderate Weight is important for determining the amount dehydration, which are descriptive terms used in of oral or intravenous fluid to be given in treatment many textbooks: plans B and C. Moderate dehydration (7?10% loss of body not be recorded on a growth chart, as it will be weight) causes children to be restless, ?fussy, or lower than normal owing to dehydration. The eyes are somewhat sunken and the the child should be weighed again after rehydration mouth and tongue are dry. There is increased thirst: has been completed and that weight should be older patients ask for water and young children recorded on the chart. If possible, children with drink eagerly when offered fluid from a cup or no signs of dehydration should also be weighed spoon. The is detectable, but rapid, and the fontanelle in infants assessment of hydration status is difficult in children is somewhat sunken. If Using a patient record form possible, a fresh stool specimen should also be Information on the history, examination, and observed for visible blood. If bloody diarrhoea is treatment of each patient should be summarized present, the patient should be considered to have on a ?Patient Record Form. If dehydration is present it should also of this form may be used, but they should include be treated immediately. Persistent diarrhoea patients with bloody regards measles; stool or a stool culture positive for Shigella should. If Giardia cysts, or findings following rehydration therapy at the health trophozoites of either Giardia or E. It also with persistent diarrhoea, therefore such drugs helps remind the healthcare worker of all of the steps should not be given. Completed forms should be kept at Sometimes it is difficult to determine whether a the health facility and reviewed regularly to identify child has persistent diarrhoea or is having sequential areas where management practices could be improved. Patients with persistent Page 66 Module 3 diarrhoea usually have loose stools every day, history and an examination to determine whether although the number per day may vary the child is adequately nourished or considerably. Additionally, in areas where have normal stools for one or two days after which vitamin A deficiency is a public health problem, diarrhoea resumes. If the period of normal evidence of such deficiency should be sought and (formed) stools does not exceed two days, the illness treated. In turn, malnutrition contributes to diarrhoea, which is more severe, Animal milk or infant formula prolonged, and possibly more frequent. When these steps are followed, malnutrition can be either prevented or corrected and the risk of Weaning foods (for children aged 6 months or older): death from a future episode of diarrhoea is much At what age were soft foods started? Do these contain A brief nutritional assessment should be carried out vegetables, pulses, oil, fruit, eggs, or meat? Page 67 problems and to obtain the information needed How much food is given and how to make dietary recommendations. Absence of subcutaneous fat; the skin is Is breast-milk given more often, as usual, or very thin less often? The following examinations may be performed: Weaning foods Have these been continued? Weight-for-age: this is the simplest measure of How frequently has food been offered? Weight-for-age is most What does the mother believe about giving valuable when recorded on a growth chart and used breast milk, animal milk, formula, or other to monitor growth over time; a series of points fluids or foods during diarrhoea? This may have the Mid-upper arm circumference: this test involves features of marasmus, kwashiorkor, or both. It is simple to perform (a weighing Signs of marasmus scale is not required) and valuable as a screening. If height ratio is valuable because it detects children rectal thermometers are available and can be with recent weight loss (wasting); however, two disinfected after use, they are preferred. Any child with a history of recent fever length are more difficult to measure accurately than or with a temperature of 38 C or greater should weight. Such children should also be carefully checked for signs Each of the above measurements should be or symptoms of another infection. If the latter are used, national guidelines must be followed for their interpretation in the local setting. Measles vaccination status the mother should be asked whether her child has already received the measles vaccine. Children between 9 months and 2 years Vitamin A deficiency of age who have not previously been immunized Night blindness: ask the mother if her child is should receive the measles vaccine. Night blindness is difficult to recognize in children who Treatment are not yet old enough to walk. Feeding should be continued during all types of in the temporal part of the scleral conjunctivae. Antimicrobials and antiparasitic agents should not the cornea that are roughened or ulcerated. Module 3 Page 69 Consequences of watery diarrhoea Exceptions to this are: Diarrhoea stools contain large amounts of sodium. All the acute antibiotic effective for Shigella; cases not effects of watery diarrhoea result from the loss of responding to this treatment should be studied for water and electrolytes from the body in liquid possible amoebiasis. Suspected cases of cholera and/or persistent are lost when there is vomiting and water loss is diarrhoea, when trophozoites or cysts of Giardia further increased by fever. These losses cause are seen in faeces or intestinal fluid or pathogenic dehydration (due to the loss of water and sodium enteric bacteria are identified by stool culture. Among Since the mainstay of diarrhoea treatment involves these, dehydration is the most dangerous because maintaining an adequate fluid intake to compensate it can cause decreased blood volume for the fluid and electrolytes lost owing to (hypovolaemia), cardiovascular collapse, and death diarrhoea, it is important to understand the if not treated promptly. Isotonic dehydration this is the type of dehydration most frequently caused by diarrhoea.
