The syndrome may be peracute in which case sudden death occurs without any premonitory signs spasms left upper quadrant order genuine lioresal on-line. The acute disease is characterised by stiff gait or recumbency muscle relaxant yellow pill lioresal 10 mg free shipping, depression muscle relaxant gaba buy lioresal 25mg fast delivery, fever muscle relaxant adverse effects cheap lioresal generic, hyperaesthesia and tetanic convulsions muscle spasms xanax cheap 25 mg lioresal with visa. No gross pathological lesions are observed in peracute septicaemic colibacillosis because of sudden death spasms on left side of body discount lioresal 25 mg without a prescription. In the acute form there are widespread subserosal and submucosal petechial haemorrhages. Enteric colibacillosis is manifested mainly by a haemorrhagic or mucoid diarrhoea various degrees of diarrhoea and slight fever. Other enteropathogens such as rotaviruses, salmonellae and Campylobacter spp may also be involved and complicate the clinical picture. Pathologically there are widespread haemorrhages in the intestinal mucosa and large numbers of the bacteria can be demonstrated in smears from the intestinal mucosa. Diagnosis the epidemiology, clinical signs, pathological features and, response to treatment may support a presumptive diagnosis of colibacillosis. Bacterial culture alone is of limited use because of the presence of non-pathogenic strains of E. In the peracute form of the disease the organisms may be isolated from abdominal viscera and heart blood. The differential diagnosis of colisepticaemia include clostridial enterotoxaemia and salmonellosis. These conditions can be confirmed by isolation and identification of the causative bacteria. The differential diagnosis of enteric colibacillosis include dietetic diarrhoea, coccidiosis and campylobacteriosis. Dietetic diarrhoea is manifested by passage of voluminous and pasty or gelatinous faeces and the animals are usually bright or alert although they may be inappetent. Other enteritides can be differentiated by isolation and identification of their aetiologic agents 54 Treatment and Control In view of the diversity of strains of E. Trimethoprim-sulphonamide combination (15-25 mg/kg) and kanamycin (20 mg/kg) given parenterally and colistin administered at a rate of 1-2 g/kg in drinking water have been found to be effective in the treatment of the disease. Other antibiotics such as oxytetracycline, neomycin, chloramphenicol and sulphadimidine are also used. Vaccination of dams 2-4 weeks before parturition to stimulate production of specific antibodies is recommended in order to provide passive protection bf neonatal lambs and kids through colostral immunoglobulins. Ewes have to be vaccinated twice in their first year of lambing, first at 8-10 weeks and then at 2-4 weeks before lambing. In subsequent years, one vaccination 2-4 weeks before parturition has been found to be satisfactory. Maintenance of good hygiene in the animal environment can reduce transmission and incidence of the disease. Provision of adequate colostrum to newly born kids and lambs will help to protect them from colisepticaemia. Salmonella spp are enteric bacteria and carrier animals shed the organisms in faeces thus contaminating the environment. Active carriers constantly shed the organisms in faeces whereas, passive carrier will shed the organisms when stressed and, they may also manifest an overt disease. Animals may acquire the infection through food of animal origin and pastures contaminated with infective slurry or improperly treated fertilisers. Watering points may be contaminated with slurry from infected herds or fertilisers. Intensification of animal management favours spread of the disease from carriers animals. The organisms may be introduced in the herd via contaminated feed stuffs, formites, birds or nematodes. Stresses such as transport, starvation, parturition, overcrowding in communal grazing land, holding yards and dips activate latent infections and favour rapid spread of the disease. Disruption of the intestinal flora by factors such as antibiotic therapy, change of diet and water deprivation increases the susceptibility of the host to infection. Infection in animals occurs mainly by ingestion but in sheep it has been shown that infection may also be acquired by inhalation of infective material. Pathogenesis the ability of Salmonella spp to produce disease is facilitated by the presence of virulence factors. It has been found that pathogenic salmonellae posses adhesive pili, protective plasmids and, produce an enterotoxin, cytotoxin and lipopolysaccharide. These act together and enable the bacteria to adhere and colonise the intestinal epithelium, survive the phagocytic activity of macrophages and increase the permeability of the intestinal epithelium. The presence of bacteria on the intestinal wall also initiates an inflammatory response. After successful establishment, colonisation and disruption of the integrity of the intestinal wall, the organisms the pass through lymphatic system to mesenteric lymph nodes after which a clinical disease may occur depending on the virulence of the organisms, immune status and age of the host and, presence of intercurrent infections or other stress factors. From the mesenteric lymph nodes, the organisms invade the reticuloendothelial cells and then enter the blood stream causing septicaemia, enteritis and localisation in various tissues. Clinical features Enteric salmonellosis is the commonest form of the syndrome encountered in sheep and goats. Shallow and fast respiration, rapid pulse and congestion of the mucosae are observed. There may also be dehydration, toxaemia, loss of weight, prostration, recumbency and death. New-born animals that survive the septicaemic disease develop severe enteritis characterised by diarrhoea. Pathological features Acute enteritis is characterised by muco-haemorrhagic enteritis and submucosal petechiation. The intestinal contents are putrid, mucoid, blood-tinged or may contain frank blood. There is also enlargement and fatty degeneration of the liver; thickening of the gall bladder wall and presence of blood-stained fluid in the serous cavities. The histopathological picture is characterised by necrosis, oedema, congestion and infiltration of the lamina propria and submucosa of the caecum, colon and small intestine with neutrophils, lymphocytes, plasma cells and macrophages. Focal necrosis in the mesenteric lymph nodes and thrombosis of the submucosa vessels occur. Hepatocellular necrosis and neutrophilic and mononuclear cell infiltration in the portal tracts may be evident. Necrosis and neutrophilic infiltration in the 56 mesenteric lymph nodes and lymphoid and reticuloendothelial hyperplasia occur in protracted cases. Diagnosis A provisional diagnosis can be based on the epidemiological, clinical and pathological features and the disease can be confirmed by bacterial isolation and serotyping. In the acute disease the bacteria are present in heart blood, spleen, liver, bile, mesenteric lymph nodes and intestinal contents while in chronic cases, the bacteria can be isolated from the intestinal lesions or other viscera. Lymph nodes which drain the caecum and lower intestine have been found to be rich in the bacteria. The organisms can be easily demonstrated in a thick smear made from the wall of the gall bladder. Selective media such as MacConkey agar, brilliant green agar, triple sugar iron agar and xylose-lysine deoxycholate medium are used in the isolation of Salmonella spp. Species-specific antibodies may be used to diagnose the disease but cross-reaction do occur. Coccidiosis, campylobacteriosis and parasitic gastroenteritis should be considered in the differential diagnosis of salmonellosis. Unlike the above conditions, salmonellosis is often manifested by a more acute and often fatal enteritis. High faecal oocyst and demonstration of developmental stages of Eimeria on the intestinal wall may be highly suggestive of coccidiosis whereas, high faecal egg and worm burdens may be highly suggestive of parasitic gastroenteritis. These features are not observed in salmonellosis except when they occur as intercurrent infections. Campylobacteriosis can be differentiated by demonstration of Campylobacter spp in faeces. Salmonellosis can be treated using chloramphenicol (20 mg/kg) infused intravenously at 6 hours interval for 3 days. Other drugs include trimethoprim-sulphadoxine combination, sulphadimidine, framomycin, ampicillin and amoxycillin. Oral nitrofurazone daily for 5 days mixed in the feed or as a drench is commonly used in mass medication during outbreaks. It is important to remember that oral antimicrobial therapy may disrupt the normal intestinal flora and increase host susceptibility to the disease. Supportive fluid therapy to alleviate the effects of dehydration and electrolyte loss is beneficial. In some countries, treatment of animals against salmonellosis has led to selection for drug resistant strains thus complicating the effectiveness of treatment of human cases of the disease. Salmonellosis can be controlled by avoiding faecal contamination of feed or water and maintaining good hygiene in the animal houses. Animals should be purchased from herds which are known to be free from the disease. Regular testing should be carried out to identify carriers which should be culled. Infected premises should be properly disinfected and the infective materials should be destroyed. Personnel from infected herds should not be allowed to come into contact with disease free animals. The disease has a multiple aetiology but Staphylococcus aureus and Streptococcus agalactiae are 57 the commonest bacteria isolated from cases of mastitis in small ruminants. Other bacteria encountered in include Corynebacterium pyogenes, Klebsiella spp, Mycobacterium spp and Brucella spp. Epidemiology Reports on clinical mastitis in small ruminants are available from South Africa, Kenya and Nigeria and, information from other countries is limited. This lack of information is probably be related to the fact that the indigenous small ruminants are kept primarily for meat and, hence little attention has been paid to the economic significance of mastitis. However, with recent introduction of dairy goats and intensification of management systems, mastitis may become an important disease entity worth attention. Un-hygienic conditions in animal houses and poor milking hygiene are important predisposing factors. Mechanical or surgical wounds in the teats or udder facilitate penetration of the bacteria. Most often, Mycobacterium spp and Brucella spp spread systemically and lodge in the mammary tissue causing mastitis. Pathogenesis After entry through the teat canal the bacteria colonise and multiply in the mammary tissue. Some bacteria produce enzymes and toxins which cause inflammation and damage to the mammary tissue, Pyogenic bacteria cause abscessation and suppuration. The severity of infection is determined by the virulence of the organism, extent of mammary tissue damage, stage of lactation and efficiency of host defence mechanisms in the mammary tissue. Clinical features the clinical signs of acute staphylococcal mastitis in goats include restlessness, elevated pulse (up to 144 per minute) and respiratory rate (up to 80 per minute) rates, hot, painful and enlarged mammary glands. On palpation there is marked diffuse induration of the mammary glands and enlargement of the supramammary lymph nodes. Pathological features the affected mammary glands are enlarged and hard on palpation. Diagnosis A tentative diagnosis is based on the clinical signs especially presence of abnormalities in milk and pathological lesions. Confirmation is achieved by isolation or demonstration of the causative agents in smears prepared from pus or milk secretions. Treatment and Control Bacterial mastitis can be treated by penicillin, streptomycin, oxytretracycline and gentamycin either as intramammary infusions or parenterally in systemic cases. Combination of systemic and intramammary antibiotic therapy is beneficial where there is systemic involvement. Proper herd and milking hygiene is the most effective means of controlling mastitis. Other bacteria such as Mycobacterium spp, Listeria spp, Actinobacillus spp and Actinomyces spp cause disease syndromes in small ruminants, the clinical and pathological features are similar to those observed in cattle.

Coping with Flare-Ups Flare-ups are relatively short increases in usually stable pain intensity that may last from minutes to weeks spasms piriformis order lioresal. While they may be managed in part by medication spasms coughing discount lioresal 25mg free shipping, Veterans should be encouraged to prepare for these times and identify newly acquired skills that can be used to address fare-ups most effectively spasms kidney stones cheap lioresal 10mg on-line. The best way to prevent a relapse to previous poor functioning is to be prepared for pain exacerbations and diffcult days spasms calf buy 10 mg lioresal with amex. Discuss anticipated obstacles that are likely to arise in the future as well as how those issues will be addressed stomach spasms 6 weeks pregnant buy lioresal mastercard. For example spasms while sleeping cheap lioresal on line, instead of listing stress, defne it further by listing the source of stress such as, kids fghting with each other. This is an opportunity to review all the ways to manage pain that have been explored over the last 10 sessions. Reviewing options for managing each specifc stressor can help make the exercise more realistic and implementation easier. First, it can assist in mitigating diffcult situations and minimizing the triggers previously discussed. Second, it shows Veterans how to incorporate various positive coping techniques into their everyday lives. Third, creating a plan helps imbue a sense of structure and purpose into daily life, something that is valuable for everyone. Working through a plan together will help reveal how all of the pieces ft together and increase confdence moving forward. Use the Weekly Activities Schedule, to formulate an example of a typical week for Veterans. Encourage them to think of each piece of the plan as an appointment that is not optional. Without this commitment to an identifed and distinct structure, Veterans are more likely to fall back into a sedentary lifestyle where one day is diffcult to discern from the next. In addition, a concrete schedule may help in ensuring follow-through and increasing feelings of accomplishment. It may be benefcial for Veterans to get a large whiteboard for home where the weekly calendar can be posted, and where each activity can be checked off as completed as the day progresses. Rewarding oneself for engaging in all scheduled activities for one week may be another incentive to stay the course. Ask about specifc behaviors that they want to avoid doing or saying, and use these to develop items for the schedule that will combat negative habits. For example, if someone wants to avoid isolating from others, perhaps Meeting my friend John at Java Hut for coffee can be scheduled for every Tuesday morning. It is important that the schedule is realistic, since making unreasonable plans will only make self-disappointment more likely if goals are not achieved. Explore goals that have been achieved throughout the course of treatment and how they may be expanded. For example, if the Veteran has begun meeting with friends once a week as a way to increase socialization, ask how that goal might change over the next 6 to12 months. Veterans may want to increase the frequency of outings to twice per week, or join an organization like their local Elks Lodge. Perhaps now that the Veteran has largely overcome a fear of movement, fnding and using a bicycle regularly is desired. If negative cognitions have kept Veterans from considering dating, they may now feel confdent enough to begin exploring ways to meet others. Discuss what the individual Veteran is motivated to accomplish in the future, and tailor goals to meet specifc interests and needs. Here is an example of Juan discussing discharge planning with his therapist: Therapist: Early in treatment, you developed three individual goals: 1. I also plan to keep an eye on the clock and get up once an hour, walk around, and do some stretches to better pace myself. The next thing is to get an interview so I am going to speak with someone from Vocational Rehab about my job options. Juan: Well, I have the times I get up and go to bed, take my medication, do walks and exercises, even look for a job on the computer. Having a concrete plan is important for your continued ability to manage your pain and your mood. Now that your pain is better managed, you may fnd that you are better able to focus on managing your depression. Therapist Manual 85 Practice Provide positive feedback about all that has been accomplished so that Veterans leave feeling supported and confdent. Assure them that even if obstacles or setbacks are encountered, they now have all of the tools necessary to manage their chronic pain. Remind them that they have the Anticipating Obstacles Worksheet as well as the Weekly Activities Schedule and should fnish them if that was not completed in session. Stress the importance of scheduling activities each week to help ensure continuing beneft from what they have learned. Finally, discuss scheduling a booster session in four to six weeks to follow up with progress and challenges that occur following this session. It is important to make sure that the Veteran also knows what to do in the event of any signifcant crises that might arise prior to the booster session. Overall mood, signifcant life events since the last contact, and current pain-related functioning should be assessed. Attempt to gain an overall sense of mood and emotional state in the absence of weekly contact. If mood has been poor, additional time should be spent determining the root of issues with negative effect. If additional follow-up from a mental health provider is indicated but not established, take appropriate steps for follow-up. If signifcant negative life events are reported, appropriate time and attention should be spent addressing the issues revealed. Urge Veterans to be honest regarding the obstacles that they have encountered so that an alternate plan can be developed. Focus on areas that are more salient based on the data gathered during the session. For example, if the Veteran has reported several occasions of not attending family activities because of pain, discussing the dangers of avoidance and potential benefts of approach would be appropriate. If patients have reverted back to a low level of activity and have resumed resting and guarding for much of the day, discuss the dangers of avoidance as well as the benefts of using time-based pacing and engaging in regular, moderate activity. If one of the relaxation strategies has been implemented regularly, inquire about the specifc times used and benefts obtained. Therapist Manual 87 A common issue that arises at follow-up is the return to using automatic negative thoughts on a routine basis. Sheila: Things were going great when I was coming to see you and I thought I had a handle on it, but now everything is bad again. Therapist: Have you continued to do any of the things to manage your pain that you learned in our sessions Sheila: Well I was walking and swimming regularly but now I am back to spending most of my time on the couch. I do still use the relaxation breathing to help me deal with some of the emotional stress and that seems to help my pain. Therapist: It sounds like those automatic negative thoughts are a big factor in your low mood and avoidance of effective pain management tools. Future Plans Since each person will have a different presentation at the time of the booster session, the therapist must skillfully choose the materials and feedback that will be most benefcial. It is hoped that this manual will be helpful for clinicians new to treating Veterans with chronic pain, and will also be a useful resource to those more experienced pain psychologists seeking to enhance their skills or access additional session materials.

It is caused by one of the three related polio viruses muscle relaxant whiplash order lioresal 10 mg visa, types 1, 2 and 3 which comprise a subdivision of the groups of enteroviruses. Treatment guidelines Give supportive therapy Prevention this disease is preventable by immunization with polio vaccine starting at birth. It is almost always caused by one or another of the hepatitis viruses; A, B, C, and delta viruses. These ranges from asymptomatic and inapparent to fulminant and fatally acute infections. Subclinical persistent infections with hepatitis virus B and C may progress to chronic liver disease, cirrhosis and possible hepatocellurlar carcinoma. Treatment guidelines Treatment is mainly supportive; the condition can be self-limiting (healing on its own) or can progress to fibrosis (scarring) and cirrhosis. Clinical presentation History of direct exposure to a previously jaundiced individual. Differential diagnosis Before jaundice appears, the symptoms are those of non-specific enteroviral diseases Note: Hepatitis mainly resolves spontaneously (95%) but rarely complicates into fulminant Hepatitis that is fatal. Elevated alkaline phosphatase, gamma glutamic acid and total and direct (conjugated) bilirubin levels are indicators of the degree of cholestasis, which may be a result of hepatocellular and bile duct damage. Prevention General measures: Sanitation and hygiene that includes hand washing, proper disposal of infectious materials. Mode of transmission Mainly through parenteral, sexual and vertical transmission 5% Clinical presentation the symptoms are non-specific, consisting only of slight fever (which may be absent) and mild gastrointestinal upset Visible jaundice is usually the first significant finding Dark urine and pale or clay-coloured stools Hepatomegaly is present Occasionally a symptom complex (caused by antigen-antibody complexes) of macular rash, urticarial lesion, and arthiritis antedates the appearance of icterus. Treatment Supportive o Low fat diet, oral fluids, o Give paracetamol (dose as above) if pain present Specific treatment o the use of interferon alfa in children has not yet established. Acute infection is often milder than Hepatitis A with moderately raised transaminases. Rabies Rabies is a zoonotic (transmitted from animals) viral neuroinvasive disease caused by a virus that belongs to genus lyssavirus in the family Rhabdoviridae. It is transmitted most commonly to human by a bite from an infected animal but occasionally by other forms of contact. Rabies is almost invariably fatal if post-exposure prophylaxis is not administered prior to the onset of severe symptoms. The incubation period of the disease depends on how far the virus must travel to reach the central nervous system, may take one week to six months. Once the infection reaches the central nervous system and symptoms begin to show, the infection is practically untreatable and usually fatal within days. Early-stage symptoms of rabies are malaise, headache and fever, later progressing to more serious ones, including acute pain, violent movements, uncontrolled excitement, depression and inability to swallow water. Finally, the patient may experience periods of mania and lethargy, followed by coma. In unvaccinated humans, rabies is almost always fatal after neurological symptoms have developed, but prompt post-exposure vaccination may prevent the virus from progressing. For rabies-exposed patients who have previously undergone complete pre-exposure vaccination or post-exposure treatment with cell-derived rabies vaccines, antirabies vaccines are given at days 0 and 3 regardless of route of administration i. The same rules apply to persons vaccinated against rabies who have demonstrated neutralizing antibody titres of at least 0. Transmission the natural reservoir of the virus is unknown, the manner in which the virus first appears in a human at the start of an outbreak has not been determined. Researchers have hypothesized that the first patient becomes infected through contact with an infected animal. Signs and symptoms start with sudden onset of fever, intense weakness, muscle pain, Headache and Sore throat. These symptoms are followed by vomiting, diarrhea, rash, impaired kidney and liver functions. In some cases; rash, red eyes, hiccups, both internal and external bleeding can occur. Treatment There is no specific treatment, cure, or vaccine for Marburg Hemorrhagic fever. These include: o Fluid and Electrolyte balancing o Maintaining oxygen status o Blood transfusion and clotting factors o Treat for any complicating infections. It is related to Ebola virus and a parent type belongs to Viral Hemorrhagic fevers of Filoviridae family. Mode of transmission How the animal host first transmits Marburg virus to humans is unknown. However, humans who become ill with Marburg hemorrhagic fever virus may spread virus to other people. For example, persons who have handled infected monkeys and have come in direct contact with their fluids or cell cultures have become infected. Spread of the virus between humans has occurred in a setting of close contact, often in a hospital. Droplets of body fluids, or direct contact with persons, equipment, or other objects contaminated with infectious blood or tissues are all highly suspect as sources of disease. Transmission through infected semen can occur up to seven weeks after clinical recovery. Signs and symptoms are into two phases: Phase One: Sudden onset of fever, chills, headache and myalgia. Phase Two: Maculopapular rashes, Trunk rash, Nausea, Vomiting, Sore throat, Abdominal pain, Diarrhea, Jaundice, Pancreas inflammation, Severe weight loss Liver failure, Massive hemorrhage (all orifices), Multi-organ dysfunction, Delirium, Shock, and Death. These include: 353 P a g e o Fluid and Electrolyte balancing o Maintaining oxygen status o Blood transfusion and clotting factors o Treat for any complicating infections. Transmission to human is mainly through direct or indirect contact with blood or organs of infected animals. The virus can be transmitted to human through the handling of animal tissue during slaughtering or butchering, assisting with animal births, conducting veterinary procedures. Signs and symptoms are Influenza like illnesses: sudden onset of fevers, headache, myalgia, backache neck stiffness photophobia and vomiting. Most human cases are relatively mild small proportion develop a much more severe disease. Symptoms last from 4-7 days after which the immune response to infection becomes detectable with appearance of IgM and IgG. Most of human cases are relatively mild and of short duration so will not require any specific treatment. Though many cases of yellow fever are mild and self-limiting, the disease can also be a life threatening causing hemorrhagic fever and hepatitis. It is endemic in equatorial Africa and South America, with estimated 200,000 cases and 30,000 deaths annually. Once infected, mosquitoes remain so for life Treatment, prevention and control No specific anti-viral treatment, supportive therapies are recommended. Prevention and Control involve mosquito control and provision of yellow fever vaccine. Table 2: the schedule for immunization for children is as follow: Age Vaccine Type of vaccine/state Disease Remarks (dose, Protection prevented site and route) Birth 1. Pentavalent Liquid Hepatitis B (Left thigh) Haemophilus influenza type b infections 3 Months 1. Pentavalent Liquid (Left thigh) Full dose 10 years 9 Months Measles Live attenuated / Freeze Measles 0. Onset of kala-azar is shown by low grade fever, splenomegaly, enlarged liver and lymphadenopathy. In the cutaneous form, single or multiple lesions are found on exposed parts, from where Leishmania Donovan bodies can be demonstrated. If parasites persist, treatment may be repeated, two to three times with a ten day interval in between. Since an immediate hypotensive reaction may occur, patients should lie down during the injection and adrenaline should be at hand. Further, due to possible nephrotoxicity, urine must be examined for albumin and/or casts. Treatment Medicine of choice Suramin is the medicine of choice for the early stages of African trypanosomiasis (T. The patient is then rested for 5-7 days and then the above regime of melarsoprol is repeated. This is done once again after a further rest of 5-7 days, thus completing 3 courses of melarsoprol. However, man is infected directly through contact with infected hides or inhalation of spores in the lungs or ingestion of infected meat. The main clinical features are itching, a malignant pustule, pyrexia and rarely pulmonary and gastrointestinal signs. V every 6 hours until local oedema subsides then continue with A: Phenoxymethylpenicillin 250 mg 6 hourly for 7 days. Children Premature infant and neonate A: Benzylpenicillin 6mg/kg body weight every 6 hours until local oedema subsides then continues with A: Phenoxymethylpenicillin 62.

The common causative organisms of the disease are either staphylococcus or streptococcal bacteria. Clinical features of a breast abscess are tenderness, swelling, red, warm, fever and painful lymph nodes. Instruct the patient to apply hot compresses and a constriction bandage to relieve pain in the affected breast, and to express milk if applicable to reduce engorgement. The main disease forms are bubonic, septicaemic and pneumonic with the former being the commonest. The incubation period is within 7 days and case fatality rate may exceed 50 to 60% in untreated bubonic plague and approaches 100% in untreated pneumonic or septicaemic plague. Treatment When preliminary diagnosis of human plague is made on clinical and epidemiological grounds: Subject the patient to appropriate antimicrobial therapy without waiting for definitive results from the laboratory. Each febrile episode ends with a sequence of symptoms collectively known as a "crisis. This phase is followed by the "flush phase", characterized by drenching sweats and a rapid decrease in body temperature. Overall, patients who are not treated will experience 1 to 4 episodes of fever before illness resolves. It is transmitted to humans by a bite of soft tick infected by spirochetes known as ornithrodrous moubata. Treatment 361 P a g e Treatment involves antibiotics often tetracycline, doxycline erythromycin and penicillin. The major nutritional disorders in Tanzania, in ranking order, are: Protein-energy malnutrition (deficiency of carbohydrates, fats, protein) Nutritional anaemia (deficiency of nutrients that are essential for the synthesis of red blood cells i. These include: Overweight/obesity Disorders associated with various vitamin deficiencies Disorders associated with deficiency of some trace minerals 1. With regard to manifestation, clinical and anthropometric features are distinguished: 1. Casually the child may appear normal, but on close examination, the child looks thinner and smaller than other children of the same age. He has very severe muscle wasting with flaccid, wrinkled skin and bony prominence. There is failure of growth but the child is not as severely wasted as in marasmus. The child shows hair changes (having turned brown, straight and soft) and rashes on the skin (flaky paint dermatitis). It reflects failure to receive adequate nutrition over a long period of time and is also affected by recurrent and chronic illness. This is a composite indicator which takes into account both chronic and acute malnutrition. Causes include inadequate maternal food intake during pregnancy, short maternal stature and infection such as malaria. Cigarette smoking on the part of the mother also is associated with low birth weight. Most common medical complications in severely malnourished children include generalized oedema, hypothermia, hypoglycaemia, dehydration, anaemia, septicemia/infections and cardiac failure. Treat complications eg dehydration, shock, anemia, infections, hypothermia, hypoglycemia and electrolyte imbalance.

Aspirin may also cause blood loss and iron deficiency by increasing normal gastrointestinal blood loss (0 spasms in upper abdomen buy generic lioresal 25 mg on line. Gastrointestinal parasites are a major cause of blood loss in many parts of the world. The typical laboratory signs of iron deficiency only appear after the stores of ferritin and hemosiderin have been completely exhausted. The drop in serum iron limits hemoglobin synthesis, resulting in initially normocytic and normochromic anemia. Iron deficiency affects body organ function in many ways, some overt, some subtle. Work capacity, exercise tolerance, and productivity decline in direct proportion to the decrease in hemoglobin. This is of considerable economic importance in developing countries, where iron deficiency is common and physical labor very important. Since iron is present in many enzymes (cytochromes, cytochrome oxidase, xanthine oxidase, catalase, succinate dehydrogenase, peroxidases, etc. Nearly half of the enzymes of the Krebs cycle contain iron or require it as a cofactor. Severe iron deficiency is associated with cheilosis (fissures at the angles of the mouth), atrophy of lingual epithelium, and brittle fingernails and toenails, which are flat or concave (spoon nails) [. There is now an important body of evidence showing delayed sensory development, motor function, and language skills in young children with iron deficiency. These do improve slowly with correction of iron deficiency, but children are still not back to normal some years later. Iron deficiency sometimes creates a desire to eat odd substances such as ice, clay, or starch, a disorder called "pica. Parenteral iron is usually reserved for patients unable to tolerate or absorb oral iron: 1. Anemia of Inflammation Inflammation that lasts for weeks regularly leads to anemia. While iron deficiency is the most common cause of anemia worldwide, anemia of inflammation is the second most common cause and the most common type of anemia in hospitalized persons. Inflammation may be due to infection, such as pneumonia, to an inflammatory disease like rheumatoid arthritis, or to a malignant tumor, even when symptoms of inflammation are not apparent. The anemia of inflammation (aka, the anemia of chronic disease) has three pathophysiologic mechanisms Sequestration of iron in macrophages, resulting in low plasma iron levels. All of these effects are due to the release of various cytokines in inflammatory states. The most important of these mechanisms is the reduction in plasma iron, making less available for red cell production. Bacterial polysaccharides and the cytokine interleukin 6 generated during inflammation are powerful stimulators of hepcidin production by hepatocytes. Initially the anemia is normochromic and normocytic, but with prolonged inflammation, microcytosis develops. In contrast to true iron deficiency anemia, in inflammation, storage iron as reflected in the serum ferritin is normal or elevated. The drop in serum iron is thought to be beneficial to the host as it deprives invading bacteria of an essential growth factor. Hepcidin itself has bactericidal properties in vitro and may contribute to host defenses. The optimal treatment of the anemia of inflammation is the elimination of the cause of the inflammation. With each temperature elevation, the plasma iron drops sharply and returns to normal shortly after cessation of fever. Low Erythropoietin Anemias In addition to inflammation, a variety of chronic medical conditions can cause decreased erythropoietin production, which in turn causes a hypoproliferative anemia. Other examples of conditions that cause low-erythropoietin anemia include endocrine deficiency states and severe malnutrition. Chronic Kidney Disease Anemia usually appears when the creatinine clearance falls from the normal adult level of about 100 ml/min to about 25 ml/min, indicating a 75% loss of renal function. The severity of anemia correlates roughly with the degree of renal failure and is largely due to destruction of the renal erythropoietin-producing mechanism. Young reticulocytes usually are not observed in the circulation, despite the severity of the anemia, because erythropoietin levels are depressed. Injections of recombinant erythropoietin dramatically improve anemia in patients with chronic renal failure. This treatment both eliminates the need for transfusions and improves the quality of life. Relationship between hematocrit and plasma erythropoietin in patients with chronic renal failure, with and without kidneys. As a result, the kidney needs to generate less erythropoietin to maintain its own oxygen tension in the normal range. This right shift is one reason that the hematocrit is lower in children than in adults. Anemias Due to Marrow Damage Aplastic anemia Aplastic anemia is a heterogeneous group of conditions in which the marrow is severely hypocellular. The diagnosis of aplastic anemia is made from the combination of low hematocrit and white cell count or platelet count and markedly reduced cellularity on bone marrow exam. As in other hypoproliferative anemias, the reticulocyte count is low for the degree of anemia. The serum iron is elevated because of the marked decrease or absence of erythroid precursors to take up iron from transferrin. If body iron stores accumulate to the 15-20 gram range (normal is 1 gram) for any of the reasons discussed below, tissue damage occurs. When the stores exceed the sequestration capacity of the protective storage protein ferritin, iron exists in a reactive form causing tissue injury, probably by generating free radicals. The most commonly affected organs are the liver (cirrhosis and liver cancer), the pancreas (diabetes), and the heart (congestive heart failure). Arthritis, a variety of endocrine disorders including gonadal failure with impotence, and a peculiar bronze skin color complete the clinical picture. Early recognition and removal of iron prophylactically will prevent all the life-threatening complications. This mutation appeared in a Celtic or Viking ancestor about 2,000 years ago somewhere in Northwest Europe. As its ill effects are manifest only after the reproductive period, and it might have had some survival advantage by preventing iron deficiency anemia after blood loss, the mutation spread with the migrating population. This particular mutation is uncommon or nonexistent in non-Caucasians and women are relatively spared, likely due to iron losses through menstruation or pregnancy. Recent evidence suggests that the failure of these proteins to associate leads to a failure of hepcidin secretion by the liver. Thus ferroportin continues to release iron to the plasma from duodenal enterocytes and macrophages despite very high plasma iron and ferritin levels. Starting at birth, the small increase in iron absorption from a normal value of 1 mg to 2-5 mg daily may result in accumulations of 25-50 grams by about age 50. If hemochromatosis is detected when ferritin levels are less than 1,000 ng/ml, tissue damage is unlikely. Treatment is weekly phlebotomy of 500 cc of whole blood, thus removing about 250 mg of iron each time. It may take up to two years to deplete iron stores, after which 3 to 6 phlebotomies per year will prevent iron reaccumulation. Once tissue damage occurs, it is usually irreversible, though progression is slowed by treatment. All first degree relatives of the patient should have genetic counseling and testing so phlebotomy can be undertaken early and complications prevented. Life-table survival curves after diagnosis in phlebotomy treated and untreated groups of patients with idiopathic hemochromatosis. Increased iron absorption occurs in chronic anemias that are due to ineffective erythropoiesis (thalassemia) or hemolysis. This is because anemia per se and increased marrow erythroid activity for any reason decrease hepcidin release from the liver. Iron overload is a very serious clinical problem in thalassemia major where repeated transfusions add to the iron burden. Many patients with marrow disorders that cause a chronic hypoproliferative anemia (myelodysplasia, aplastic anemia) may need repeated red cell transfusions. As the recycled iron from the senescent transfused red cells cannot be excreted, symptomatic iron overload occurs after about 100 units of blood (250 mg iron/unit x 100 = 25 grams). Iron tablets may resemble candy (M&Ms), and as few as three tablets could cause major toxicity. The gastrointestinal mucosa undergoes necrosis, leading to nausea, vomiting, and bloody diarrhea. Summary Iron is essential to life but paradoxically cannot be free in the body because of its toxicity. Elegant methods are employed by the body to conserve iron and to shield it within transport and storage proteins. It is common in young children and in women in the child-bearing years as a result of an imbalance between supply and demand, whereas in older women and men it is commonly a result of gastrointestinal losses, of which cancer is the greatest concern. Describe, and be able to recognize under the microscope, the morphologic findings in the blood and bone marrow in megaloblastic anemia. Describe the pathophysiology and the clinical and laboratory features of vitamin B12 and folate deficiency, including the important similarities and differences between them. Red cell precursors with this abnormality are called megaloblasts rather than normoblasts. Circulating red cells in megaloblastic anemia are typically larger than normal and are therefore called macrocytes. Definitions Macrocytic anemia is a subset of anemia in which the non-nucleated erythrocytes are larger than 100 femtoliters (fl). It is found in association with liver disease, alcoholism, hypothyroidism, and several forms of marrow damage as well as in B12 and folic acid deficiency. Macrocytes are red cells released before they have divided enough times to be normal-sized. For example, because reticulocytes are considerably larger than mature red cells (some young ones may be 150 fl), hemolytic anemia with a high reticulocyte count may be macrocytic on that basis alone. Megaloblastosis is the visible change in nucleated cells that results from a lag in nuclear maturation relative to cytoplasmic maturation. Folic acid deficiency is probably the most common cause of megaloblastic anemia in the general population, but cobalamin deficiency may be a more common cause in parts of the world where intake of animal protein, the dietary source of vitamin B12, is low. Megaloblastic anemia due to vitamin deficiency is a manifestation of advanced deficiency. In a referral hospital with a large proportion of cancer patients, however, the most common cause of megaloblastic change is cancer chemotherapy. Marked macrocytosis and hypersegmentation of neutrophils occur in patients treated with hydroxyurea. In normal people, most neutrophils will have two, three or four lobes, and fewer than five percent will have five lobes. The peripheral blood expressions of megaloblastosis (macrocytosis and neutrophil hypersegmentation) may occur with minimal anemia. Deficiency of Folate or Vitamin B12 Vitamin deficiency is almost invariably the result of one or more of the following five processes: Inadequate intake of folic acid is common among alcoholics and institutionalized patients. Strict vegetarians ingest very little vitamin B12 and should take a vitamin pill containing B12. Other highly restricted diets lacking in meat and fresh vegetables may produce folic acid deficiency. Drugs may prevent removal of glutamic acid residues on folic acid and thereby impair its absorption. Pregnancy and hemolysis increase the need for folate by accelerating its rate of use and are also extremely rare causes of vitamin B12 deficiency. Nitrous oxide inactivates some of the cobalamin, and may be hazardous in subjects with marginal stores. Two centuries ago, a Scottish naval surgeon, James Lind, proved that fresh lemons and limes cured and prevented scurvy among sailors, but the next clear proof of a specific disease due to a specific nutritional deficiency was not recognized until the early 20th century, when thiamine deficiency was shown to cause beriberi among rice-eating peoples of Southeast Asia. Pernicious anemia was well described morphologically and clinically for at least half a century before it was shown to be caused by a nutritional deficiency, although the distinguished American physician, Austin Flint, wrote in 1860 that the disorder was probably due to a failure to assimilate some necessary nutrient from the diet. Flint also proposed to accept the credit for his idea as soon as someone could do the work necessary to prove its validity! Unfortunately, he did not live long enough to see the proof offered by Minot and Murphy in 1926. Their work was intended to determine the most efficacious diet for the regeneration of blood, and they found, of course, that refeeding the blood to the dog was most efficacious. George Minot, an investigative physician in Boston, knew of the work of Whipple and Robscheit-Robbins and was of the opinion that pernicious anemia might be a special kind of nutritional deficiency. Thus, it had been established as early as 1926 that some substance in liver was curative for patients with pernicious anemia. The injection of liver extract every two to four weeks prevented death and neurologic disease, and corrected anemia in patients with pernicious anemia.
