They are highly resistant to damage and can be transmitted by direct and indirect faeco-oral routes cheap 60pills rumalaya with visa, mainly via contaminated food or water order rumalaya no prescription. They hatch out in the new person and the protozoa rapidly increase in number by cell division cheap 60pills rumalaya with mastercard. For accurate diagnosis buy generic rumalaya 60 pills line, laboratory identication of the cysts in the patient s stool is necessary to differentiate it from shigellosis. Advise the patient or caregiver that further investigation is needed for diagnosis and that early treatment is important because the disease could lead to serious outcomes. The cysts can be 24 Study Session 34 Intestinal Protozoa, Ascariasis and Hookworm easily transmitted in water contaminated by faeces, from person-to-person through hand-to-mouth transmission and in food. The commonest clinical manifestation of giardiasis is foul-smelling, pale, greasy diarrhoea, without blood or mucus (mucoid). The diarrhoea can be acute and resolve by itself within a few days, or it may be persistent (lasting for more than 14 days). Other symptoms of giardiasis include nausea, vomiting, abdominal cramps and abdominal distension (swelling). You should suspect giardiasis in children if the diarrhoea is persistent, but not bloody or mucoid. For children with mild non-bloody or non-mucoid Details of the specic diarrhoea, the management does not require identication of the infectious management of children with agent; cases are managed with oral rehydration as already described for simple persistent or severe diarrhoea are taught in the Module on the acute watery diarrhoea (refer back to Section 32. If a child has persistent Integrated Management of Newborn or severe diarrhoea, and giardiasis is one of the causes you suspect, treatment and Childhood Illness. In adults, you should suspect a diagnosis of giardiasis in cases with acute or persistent, non-bloody or non-mucoid diarrhoea. However, as other diseases could also have similar manifestations, conrmation of the diagnosis is needed through detection of the parasite in laboratory examination of stool samples. They have complicated lifecycles, and some helminths require transmission between humans and other host animals before they mature. There are three main groups of helminths: the roundworms, the tapeworms and the atworms (or ukes). Here we focus on intestinal roundworms (helminths that are round in cross-section), which live in the person s intestines and exit from the body in the faeces. The two commonest intestinal roundworms in Ethiopia cause the diseases known as ascariasis and hookworm infection. Neither of these conditions is characterised by diarrhoea, so they are not classied as diarrhoeal diseases. Prevention and control measures are similar to those for other faeco-oral diseases, described in earlier study sessions. However, ascariasis requires specic drug treatment based on its symptoms and signs. In Ethiopia, around 37% of the population is estimated to be infected with Ascaris lumbricoides. Adult Ascaris lumbricoides worms in the intestines (1) lay eggs which pass out with the faeces (2). The eggs hatch and lumbricoides), with measuring develop into larvae (immature stage) in the intestines (5). You can make a clinical diagnosis of ascariasis if the patient or the caregiver of a child tells you that long worms have passed with the stool or vomit, or if you are able to see the worms yourself. Eggs in the faeces are too small to see with your eyes, and although they can be identied by laboratory diagnosis of stool samples, there is no need to send samples for investigation or refer the patient 26 Study Session 34 Intestinal Protozoa, Ascariasis and Hookworm unless there are obvious signs of anaemia (see Box 34. You can treat mild cases yourself, and you should also give all children aged between two to ve years routine treatment to kill intestinal worms, as described next. Treatment for ascariasis and routine deworming If you diagnose ascariasis, the treatment schedule is as given in Table 34. There are two drugs (albendazole and mebendazole), both available in either liquid or tablet form. However, even if there are no signs of worm infection, routine deworming is recommended for all children aged 24 months or older who have not been treated in the previous six months. Give every child that you see in this category the appropriate dose of albendazole or mebendazole every six months to treat intestinal worms. For children who nd swallowing a tablet difcult, Do not give either albendazole or you can crush it between two spoons and mix it with a little water to help mebendazole to pregnant women them to take the dose. This regimen kills hookworms as well as ascaris who are in their rst 14 weeks of worms. Drug Age 0 to 2 Age 2 to 5 years years Albendazole (400 mg tablet) None 1 tablet (400 mg) Medendazole (100 mg or None 1 500 mg tablet 500mgtablets) (or 5 100 mg tablets) Mebendazole oral suspension 2. However, it is appropriate to discuss hookworm infection with other faeco-oral diseases because the infectious agents exit from the body in the faeces, the routine deworming regimen is the same as for ascariasis (Table 34. The main infectious agents are called Necator americanus and Ancylostoma duodenale. Hookworm infection is endemic in Ethiopia, especially in areas where people walk barefooted and sanitary conditions allow faeces to contaminate the soil. In Ethiopia the prevalence of hookworm infection is estimated to be around 16% of the population. The larvae then migrate to the small intestine, after passing through different body systems. In the small intestine, the adult worms mate and the females lay eggs which are excreted with the faeces. The eggs develop in the soil into larvae, which can then be transmitted to new individuals through the skin. Wearing shoes to prevent the parasites from entering through skin while walking barefooted. Using latrines, disposing of faeces safely and stopping open defaecation in elds, to prevent contamination of soil with the parasites. Diagnosis and treatment of hookworm infections Cases of chronic hookworm infection manifest with abdominal pain and the symptoms and signs of anaemia (see Box 34. It is very important that you treat worm infestations routinely in children aged from two to ve years, because persistent hookworm infections (like ascariasis) causes a signicant loss of micronutrients (minerals and vitamins) from the body. Anaemic children fail to grow properly and their school performance will be negatively affected. Haemoglobin is the red, iron-rich protein that gives red blood cells their colour and enables them to pick up oxygen and transport it around the body. In the next study session, we turn to the largest single cause of mortality among children under the age of ve years: acute respiratory tract infections. Summary of Study Session 34 In Study Session 34, you have learned that: 1 Parasitic infection of the intestines could be due to protozoa or helminths. Amoebic dysentery is rare in children, in contrast to shigellosis (bacillary dysentery) which mainly affects young children. For persistent or severe cases in children, and all adults with suspected giardiasis, start rehydration and then refer them for laboratory diagnosis and treatment. Cases present with abdominal discomfort and you may see the passage of live worms with the faeces or vomit. Treat cases with albendazole or mebendazole according to the schedule in Table 34. Refer suspect cases for laboratory conrmation and educate the community on shoe wearing, use of latrines and proper disposal of faeces. Which diseases do you suspect, if he describes the diarrhoea as: (a) Bloody with mucus? The respiratory tract (or airways ) includes all the parts of the body that enable us to breathe. The upper respiratory tract consists of the airways from the nostrils to the vocal cords in the larynx (voice box), and includes the pharynx (back of the throat) and part of the internal structure of the ear (the middle ear). The lower respiratory tract refers to the continuation of the airways below the larynx and the branching airways throughout the lungs. They are transmitted from one person to another by oh-tiy-tiss ; pharyngitis is airborne droplets spread through coughing or sneezing.
