Raised cytokine levels in McArdle people have several possible implications: 1) Many McArdle people are misdiagnosed with an inflammatory muscle disease such as polymyositis (which is often treated with steroids to reduce the inflammation) (section 2 spasms just under rib cage buy cheap pyridostigmine 60 mg on line. It is possible that the feelings of depression experienced by McArdle people could be related to increased levels of some cytokines. At present, none of these possible implications have been fully investigated or proven, so the implications are speculative. Depending what form of the second gene a McArdle person has, the severity of the symptoms could vary between McArdle people. Phenotype modulators are a possible explanation for why different McArdle people can have different symptoms. Recent research has identified several genes which appear to be phenotype modulators. People with the I isoform respond better to muscle training and aerobic conditioning. This will have the effect of increasing the size of the blood vessels, which may allow more blood to be pumped to the muscles, bringing more glucose and fatty acids and oxygen to the muscle cells. This results in the production of an abnormally short enzyme which cannot function. It may therefore have an effect upon the strength and ability of muscle to repair itself following damage. A mutation (like the K153R missense mutation) can stop myostatin being able to function. At present, the effect of the 102 K153R mutation is not known, but one possibility is that having the mutation could enable an increased amount of muscle growth which could increase muscle strength. The R577X mutation introduces a premature stop codon which results in an absence of -actinin-3. Peroxisome proliferator-activated receptor coactivator 1 is involved in regulating the expression/production of proteins involved in generating energy within the cell. Other McArdle people have pain caused by exercise, or occasionally muscle pain after exercise if some muscle damage has occurred. They asked many questions to determine whether the McArdle people only had pain caused by exercise, or whether they had permanent pain. There was only one man with permanent pain, so they used the women to compare those with permanent pain with those with exercise-induced pain. For the women with permanent pain, the pain had a greater impact on the daily life, work, and social activity. They found that those with permanent pain felt more fatigue, and tried harder to avoid pain. On the other hand, women who had permanent pain seemed to feel that the pain was greater, and worry about it. It is not obvious whether there was an original difference between the women who had exercise-induced pain or permanent pain, or whether the difference was due to differences in attitude and different methods of coping with pain. I inferred from the report that women who had exercise-induced pain found that it had less effect upon their lifestyle than those who had permanent pain. Women with permanent pain found that it had a greater effect upon their general activity, and caused sleep disturbance and fatigue. The authors do point out that this study was limited by the small number of participants (24 McArdle people), and a larger scale study would generate more useful information. The results of this study did not show any of these genes had any effect on severity of symptoms, but unfortunately, the authors did not separate the data for men and women to see if gender had any affect on the effects of the different genes. They suggested that the effects of these second mutations, and therefore the high frequency of diagnosing double trouble may be because the first muscle disease lowers the threshold for manifestation of the symptoms. There is a report of an infant girl born to consanguineous Moroccan parents, who died at 5 months of age. The boy had started to have difficult with exercise like walking upstairs from the age of 14. His muscle weakness was much more severe than that usually seen in McArdle people. Pillarisetti and Ahmed (2007) described a McArdle person who had both bulimia and sickle cell trait (by sickle cell trait the authors meant that the person was heterozygous for sickle cell anaemia). The authors said that bulimia could make rhabdomyolysis more likely because bulimia could cause electrolyte changes in the body like hypokalemia and hypophosphatemia which could also precipitate rhabdomyolysis. Epileptic seizures caused the muscles to cramp up, spasm, and produced rhabdomyolysis. This research suggests that a second disease may explain why symptoms are occasionally seen in carriers of McArdle disease. At the age of 40 he had myoglobinuria twice after heavy muscle exercise, but did not have cramps/contractures. It was found that he was a carrier of McArdle disease, and had 25% of normal muscle glycogen phosphorylase activity. Carriers do not usually have symptoms of McArdle disease (Quinlivan and Vissing, 2007 and many other publications). Alternatively, it may be that he had a second (undiagnosed) muscle disease which led to muscle degeneration as he got older and triggered McArdle symptoms. As discussed below, many McArdle people have struggled for many years to get a diagnosis, sometimes being told by family doctors that they are imagining the symptoms or are malingerers (see section 10.

Microangiopathic Hemolytic Anemias In this group of disorders spasms muscle pain purchase 60mg pyridostigmine otc, fibrin strands or platelet clots are strung across the microvasculature, or there is severe endothelial damage in the small vessels, causing red cells to fragment as they pass. These thrombi are believed to cause the clinical pentad of: renal failure fluctuating neurologic signs (seizures, paresthesias, coma) fever thrombocytopenia microangiopathic hemolytic anemia. The disorder is caused by pounding the soles of the feet against a hard surface, with mechanical trauma to the red cells. Hemoglobinuria clears six to twelve hours after exercise, and the condition is benign, though frightening. Treatment consists of retraining the runner to alter his pounding gait, adding padded insoles to the shoes, or switching to bird watching. Summary In summary, the red cell membrane is a very complex structure that evolved in response to the need for increased oxygen carrying capacity. Many different abnormalities of this membrane exist, some hereditary, some acquired. Red Cell Metabolism the red cell is the only cell in the body with no nucleus and no mitochondria. It metabolizes glucose, its basic fuel, to maintain its osmotic equilibrium, regulate the position of its oxygen dissociation curve, keep iron in the ferrous state, and prevent denaturation of its proteins and lipids. Glucose enters the red cell by a facilitated transport system that is independent of insulin. The membrane becomes so stiff that it no longer can squeeze through pores in the spleen. Oxygen is a very reactive molecule that oxidizes the very hemoglobin that transports it at a rate of 1-3% per day. Methemoglobin does not deliver oxygen, because hemoglobin that contains only ferric iron does not bind oxygen, while hemoglobin that contains some ferric and some ferrous iron has a left-shifted oxygen dissociation curve and will not release bound oxygen in tissues. Thus a mechanism must exist to continuously reduce methemoglobin +++ ++ (Fe) back to hemoglobin (Fe). Pentose Phosphate Pathway the major function of the pentose phosphate pathway is to protect the red cell membrane and globin chains from direct damage by oxygen radicals. Under normal circumstances, approximately 95% of glucose is metabolized through the glycolytic pathway; the remaining 5% is metabolized in the pentose phosphate pathway (Fig. It serves the critical function of protecting proteins and lipids of the red cell from oxidant denaturation. They can result from normal oxidation reactions (including the reactions of molecular oxygen with hemoglobin), drug metabolism, ionizing irradiation, and the killing of bacteria by leukocytes. If unopposed, these reactive species will attack hemoglobin, enzymes, and cell membranes, causing irreversible damage. As shown in the following series of reactions, glutathione reduces peroxides to water, thus protecting cellular constituents. As discussed in subsequent paragraphs, these protective mechanisms are jeopardized by enzyme deficiencies in the pentose phosphate pathway. This will occur only if an intermediate electron acceptor is given to the patient. The best known drug for this purpose is methylene blue, which is used to treat chemically-induced methemoglobinemia. In most patients, anemia, jaundice, or both are noted in infancy or in early childhood. In severe cases, hemolysis may produce neonatal jaundice, requiring exchange transfusion. This enzyme is also low in normal neonates, rendering newborns susceptible to the effects of drugs and toxins that produce methemoglobinemia. One such natural toxin is nitrate in well-water, which is converted to nitrite in the gut. The incidence is especially high in people with roots in Africa, the Mediterranean basin, and the Middle East. Along with sickle trait, thalassemia trait, hemoglobin E, and hereditary elliptocytosis, it offers some protection against falciparum malaria. Males, therefore, are hemizygotes and more likely than women to have clinical disease. In females, one of the two X chromosomes is randomly inactivated in each stem cell at the 6 cell stage of embryonic life, resulting in mosaicism (Fig 4. Patients are often identified in the neonatal period when they become jaundiced and may require exchange transfusion. The presumed mechanism is generation of superoxides and hydrogen peroxide by neutrophils and macrophages. Oxidant drugs, diabetic ketoacidosis, and the newborn period are other precipitating events. A new steady state is reached and the anemia improves even if the oxidant stress continues. When subjected to oxidant stress, severe intravascular hemolysis with profound anemia, hemoglobinuria, and jaundice may occur. As in the mild types, infection is the most common precipitating event and the hematocrit is normal between episodes. It is believed that a second hereditary defect is required in which an ingredient of the beans is aberrantly metabolized to an active oxidant. A number of other drugs are probably not safe for patients with the congenital chronic hemolytic anemia variants. On the other hand, many drugs previously thought to be contraindicated, such as aspirin and acetaminophen, have been exonerated. Oxidized globin chains precipitate and form disulfide bridges to the red cell membrane, rendering the cell undeformable. Molecular Physiology Normal adult hemoglobin contains four globin chains, two alpha and two beta. One hemoglobin molecule combines reversibly with four molecules of oxygen to form oxyhemoglobin. The sigmoid shape of the oxygen equilibrium curve is a consequence of "heme-heme interaction," or "subunit cooperativity," with oxygen binding to the first heme increasing the strength of its binding by the second, the second increasing the strength of binding by the third, and so on. This characteristic of hemoglobin depends upon its tetrameric structure and on the presence of dissimilar chains in the tetramer (two alpha and two beta chains in the case of normal adult human hemoglobin). Thus, monomers such as myoglobin yield an oxygen equilibrium curve that is a rectangular hyperbola; as does a tetramer containing only beta chains (4 =Hemoglobin H). An elegant explanation has been devised by Perutz to account for this shape of the oxygen equilibrium curve. There are ionic bonds within and between the alpha and beta chains, which stabilize the molecule. Rupture of salt bonds also causes subtle movement within the adjacent subunit such that the affinity of its iron for oxygen increases. The hemoglobin molecule, like the lung, thus "breathes" as oxygen comes and goes (Fig. The normal blood oxygen equilibrium curve (middle curve) and left and right-shifted curves. When shifted to the right, blood-oxygen affinity is reduced, P50 is higher, and more oxygen is released from blood at any given pressure. Bohr Effect In 1906 Christian Bohr discovered that hemoglobin-oxygen equilibrium was sensitive to the partial pressure of carbon dioxide in blood. Acidification of blood shifts the oxygen equilibrium curve to the right, increasing oxygen delivery to the tissues. Carbon Dioxide and Temperature Carbon dioxide also has a smaller direct effect on the hemoglobin-oxygen equilibrium. In addition to its effect on pH, carbon dioxide binds directly to the N-termini of alpha and beta chains of hemoglobin, and this binding produces a right shift of the curve. For example, during vigorous exercise, muscles produce lactic acid, carbon dioxide, and heat, all of which enhance oxygen release at the site where the oxygen is needed. By decreasing hemoglobin-oxygen affinity, it facilitates the release of oxygen from hemoglobin to the tissues. This may explain the lower hemoglobin levels seen in children as they have higher phosphate levels than adults.

Examples include myocardial infarction muscle relaxant 503 discount pyridostigmine 60mg on-line, thrombotic (occlusive) stroke, and mesenteric ischemia. Arterial thrombi can form emboli, portions of the clot that break off and travel into the distal circulation. The most common example is embolic stroke from an intracardiac thrombus caused by atrial fibrillation, valvular disease, or severe left ventricular dysfunction. Most commonly, venous thrombosis involves the deep venous system in the lower extremities or pelvis. Thrombus formation is generally cyclic, with layers enriched for fibrin and red blood cells. Pathophysiology of Arterial Thromboembolism Development of arterial thrombosis is closely linked to atherosclerotic vessel disease, making it difficult to discern risk factors for arterial thrombosis separately from factors that predispose to the underlying vessel disease. Underlying atherosclerosis is associated with increased age, smoking, hypertension, obesity, hypercholesterolemia, diabetes mellitus, family history of heart disease, and sedentary life style. The precise mechanisms by which the inflammatory and coagulation responses interact are active areas of investigation. Clinical presentation depends on the specific vascular bed involved and the acute vs. Formation of thrombus on an underlying atherosclerotic plaque is often the final event in clinical presentations such as myocardial infarction. Specific clinical syndromes are covered in your cardiovascular and neuroscience courses. Since the etiology is multigenic, we consider inheritance of defective alleles as genetic risk factors for development of thrombosis, not disease states per se. Clinical risk factors may be transient (pregnancy) and/or reversible (estrogen therapy), or represent chronic, ongoing conditions (age, obesity, malignancy). Endothelial/vessel injury o trauma o surgery/general anesthesia (especially hip and knee fracture/replacement) o pregnancy (especially post-partum) o smoking 3. These antibodies may be directed against a variety of epitopes, including cardiolipin and 2-glycoprotein I. The detection of these antibodies is common enough in the general population that their pathologic significance is unclear, unless present in high titers, in association with other autoantibodies, or in patients with other evidence of the antiphospholipid antibody syndrome. In contrast, heparin rarely causes a moderate to severe (greater than 50% reduction), late onset (5-7 days) thrombocytopenia due to development of a heparin-dependent antibody. The marked platelet activation results in moderate thrombocytopenia (due to consumption) and may trigger fulminant arterial and/or venous thrombosis. Myeloproliferative/bone marrow disorders (see chapter 8) Polycythemia vera is associated with increased incidence of venous thrombosis. Venous thrombosis and microvascular arterial events are most common, including digital ischemia. Must be differentiated from reactive thrombocytosis, which generally poses little to no risk. Each of these risk factors has a modest individual contribution to the overall risk of venous thromboembolism. Thus, even in patients with underlying genetic predisposition, thrombotic events are generally triggered by addition of one or more acquired factors (surgery, pregnancy, immobility). The relative risk for venous thrombosis compared to the general population is increased up to 20 fold in some families with hereditary antithrombin, protein C, or protein S deficiency. The relative risk in individuals with factor V Leiden or prothrombin mutation is increased ~2-5 fold. The homozygous state (complete absence of antithrombin in the blood) has never been described and is probably not compatible with life. Protein C deficiency more common (1/350 blood donors), autosomal dominant condition in which protein C activity is about 50% of normal. The homozygous state (complete or near-complete absence of protein C) results in a severe thrombotic disorder beginning in infancy (neonatal purpura fulminans). Protein S deficiency rare autosomal dominant condition, no good estimates of prevalence. The Factor V Leiden polymorphism is the most common (5% of Caucasian population) autosomal dominant condition that is associated with a 4-5 fold increase in the relative risk of venous thromboembolism. Homozygotes have substantially higher risk than heterozygotes (perhaps 50 times higher than general population). Unlike antithrombin, protein C and protein S deficiencies, which are associated with many different mutations, the molecular defect in factor V Leiden is a single base change in the factor V gene that eliminates a protein C cleavage site in factor Va, resulting in activated protein C resistance and defective termination of coagulation by activated protein C. Prothrombin G20210A polymorphism is a relatively common (2% of the general population), autosomal dominant condition that is associated with 15-30% higher levels of prothrombin antigen in the plasma. Severe elevations result from homozygous cystathionine synthetase deficiency (homocystinuria, a rare congenital disease). Mild elevations are much more common, and may result from other inherited or acquired defects in homocysteine metabolism. The mechanism is unclear, but may involve induction of endothelial procoagulant activity by homocysteine and related compounds. Lowering homocysteine levels (for example, by administration of folate and B12) has not lowered thrombotic risk, at least in the short term, in several clinical trials. Major complications include the post-phlebitic syndrome (chronic, sometimes disabling, leg swelling and pain due to venous stasis) and sudden 273 death from pulmonary embolism. Anticoagulant therapy given to prevent recurrent venous thromboembolism has significant clinical benefits, but is also associated with an increased risk of bleeding complications. The risk of recurrent venous thromboembolic disease varies significantly depending on the clinical and genetic risk factors present in a particular patient. Clinical risk factors may be transient or reversible (surgery, estrogens), or alternatively represent chronic conditions (congestive heart failure, venous insufficiency). The heterogeneity in thrombotic risk among families with single gene defects, and the lack of established risk factors in the majority of thrombophilic patients, suggests that additional unknown genetic factors are involved in the development of thrombosis in many cases. The ability to select patients with a high likelihood of recurrent venous thromboembolism for long-term anticoagulation would greatly improve the risk: benefit ratio of therapy. The multigenic etiology of venous thromboembolism and our incomplete knowledge of the risk-associated alleles significantly limit the ability to perform global genetic risk assessment. Thus, laboratory evaluation of hypercoagulable states does not contribute to the clinical management of most patients. Such testing may be helpful in selected patients presenting at a young age, and/or with a significant family history. The signs and symptoms of venous thromboembolism are sufficiently non-specific that objective testing to demonstrate the presence of thrombi is critical. Overview of therapeutic indications for Antithrombotic therapy See part 2 of this chapter for discussion of individual drugs. Oral thrombin and Xa inhibitors, discussed in chapter 11, are potential alternatives to warfarin. Often treated for 6-12 months, but optimal duration of therapy remains unclear and some patients may benefit from long-term anticoagulation. Used to prevent pulmonary embolism in patients with strong contraindications to anticoagulation, or for patients who have recurrent events while on therapeutic anticoagulation. Prophylaxis of Venous Thromboembolism Many hospitalized patients are at risk for venous thromboembolism. The most effective form of prophylaxis is anticoagulation, but the benefits of anticoagulant prophylaxis must be weighed against the risk of bleeding associated with such treatment. Mechanical methods are somewhat less effective than pharmacologic prophylaxis, but may be preferred in patients at high risk for bleeding. Anticoagulation for Atrial Fibrillation Chronic atrial fibrillation is associated with a significantly increased risk of thromboembolic stroke.

Unlike the movie the irony in the book leads the reader to ponder on the barbarity of the German leaders during the Holocaust muscle relaxant reversals order pyridostigmine american express. Write a comparison/contrast paper discussing the similarities and diferences between these two works. Keeping in mind the main characters Esperanza Cordero and Paikea Apirana, the traditions of the two cultures, Hispanic and Maori, the role of women, religion, and symbolism, compare and contrast how Esperanza and Pai bridge the past and the present for their people. Lives on mango, rides the Whale More than 8,000 miles of land and sea separate two seemingly contrasting young women. Despite the vast diferences in lifestyle and culture, both Esperanza Cordero of Chicago and Paikea Apirana of New Zealand are destined to be lead ers of their generation in spite of the multitude of traditions and expectations that defne them as indi viduals and their role as women in society. These two natural-born leaders are bridging the gap between the ancient customs and modern-day life. While culture has a huge impact on the Cordero and Apirana families, the protagonists of both groups are afected the most. The patriarchal society overwhelms every aspect of life, and Esperanza demands change through rebelling in her own quiet war. She plans to set her own example, to forge her own path, in the hopes that the oppressed women of Mango Street will realize alternative options. Desperately seeking an opportunity to fee Mango Street, Esperanza dreams of the day when she will leave just another crippled house to seek her own way in the world. According to legend, her ancestor and namesake rode on the back of a whale to this land and her family has been there ever since. She wants the best for her people and she understands that the village and tribe must modernize and change with the times or else they may lose everything. For example, in the movie Whale Rider, Pai walks into her kitchen to fnd three elder women smoking cigarettes. Both girls dream of the day where their women will be respected and treated as equals in their patriarchal societies. Family also plays an important role in both the House on Mango Street and Whale Rider. The Corderos are one happy group, with lots of strong and inspirational individuals, binding relatives togeth er like a ribbon on a present. Esperanza, the namesake and great-grandmother of the young protagonist, was a strong-willed woman. At a baptism, Uncle Nacho convinces Esperanza to dance; despite her sad brown shoes, she in fact does with her uncle telling her how beautiful she is, making her forget her discomfort and hatred of her shoes. Even though Esperanza may be loved in her family and close community, she is of low social status in general. From a typical Mexican family, Esperanza is not poor but also has never really experienced any luxury other than a used car. Pai was left to be raised by her grandparents Koro, the current chief, and Nanny Flowers. Regardless of the criticism from Koro, Nanny Flowers encourages Pai to do what she knows is best, even if that results in harsh consequences. She refuses to move even when her grandfather threatens to send her away, which he does because Pai will not give up her seat. As she walks away from the group, Nanny Flowers has a proud little smile on her lips, for she knows that Pai is ordained to be the next leader. Be cause Pai is next in line to become the chief, she is of very high status, just below the current chief. A prominent fgure on Mango Street, Esperanza presents an alternative to the oppression of women in the community. In the outside world, however, she is just another young girl with parents who immigrated to the United States in the hopes of a better life for their children. Esperanza wants to set an example for the women trapped in their houses, to provide an escape for those ensnared in the barbed wire of marriage. Above all, she dreams of the day where she can leave Mango Street, yet she knows that it is her duty to return to free her friends. Because of the rich diversity and infuences in her neighborhood, Esperanza learns through her friends and experiences they share. Marin, Rafaela, Lucy, Rachel, Sally, and Alicia all provided a learning experience in one way or another. As all of these young ladies are in a similar age range with Esperanza, they undergo multiple trials side-by-side. Always aware of the outer world, Pai knows that her people must adapt to the changing times or they will be swept away by the current of technology. She holds a great love and respect for her culture and people, and she wants what is best for them, even if it involves changing ancient traditions and ways. Pai knows it is her duty to stay, and her desire keeps her rooted in her little village. However, in the car ride along the beach, a whale calls from the depths of the ocean and it is then that Pai knows she cannot leave her people. The children of the village tease and taunt Pai for her name and her big dreams, yet she pays them no attention. Unlike Esperanza, Pai knew from the beginning that she was destined to be great and is diferent from others her age. Esperanza, although older than Paikea, has low self-esteem and little self-confdence. All this young girl wants is to make friends and be loved by others, but she gets in her own way. However, when the world seems against her and she is all alone, Esperanza writes to escape. As directed by her deceased Aunt Lupe, she continues the poetry and short stories that free her from the chokehold of Mango Street. Starting with the women, she tells them to change their ways at the ripe old age of ten. Little can shame her, except for her grandfather; all Pail wants is to be loved and accepted by Koro. While everyone in the village can see that Pai is fated to become the next chief, Koro stubbornly refuses to believe until the very end. Pai was named after her ancestor who rode the back of a whale to New Zealand, and she is exceedingly proud of her name, unlike Esperanza. And unlike Esperanza, it seems as though Pai has no time for boys or any relationships between them. Growing up with her situation and the multiple responsibilities that followed left little time for an actual childhood. In the end, the fate of two diferent cultures rests in the hands of two diferent young girls.

In addition muscle relaxant alcohol addiction order online pyridostigmine, most laboratories rely on published neonatal reference ranges, which may differ from those using different analysers and reagents. The degree of correction is unpredictable and clotting tests should be repeated after administration. Current guidelines do not recommend their routine use in the absence of further prospective studies. The T-antigen may be exposed on the surface of neonatal red cells by neuraminidase-producing bacteria such as Clostridium spp. Transfusion guidelines and blood components for older children are similar to those for adult patients (see appropriate sections of the handbook). Dedicated paediatric transfusion charts or care pathways can also reduce dosing and administration errors. It is recommended that: Red cells are transfused at up to 5 mL/kg/h (unless there is active major bleeding) and the transfusions should be completed within 4 hours (see Chapter 4). Children above 15 kg may receive a single apheresis donation (approximately 300 mL). Expert opinion now generally favours an Hb transfusion trigger of 70 g/L in stable critically ill children, which is the same as the recommendation for adult patients (see Chapter 7). A higher threshold should be considered if the child has symptomatic anaemia or impaired cardiorespiratory function. A red cell transfusion trigger of 70 g/L is appropriate for clinically stable patients without active bleeding. Platelet transfusion guidelines are also similar to those 125 Handbook of Transfusion Medicine developed for adult practice, although a higher rate of bleeding in children with haematological malignancies has been reported. In general, principles developed in adult practice have been extrapolated to the care of children (see Chapter 7). Well-rehearsed local protocols, excellent communication with the transfusion laboratory and involvement of appropriate senior staff with paediatric expertise are important elements of successful care. Emergency group O RhD negative red cells should be rapidly available, with the option of moving to group-specific blood when the identity of the patient and the blood group have been verified. The transfusion laboratory should be informed of the age and (estimated) weight of the patient to guide selection of appropriate blood components. Age-specific components should be used if available in a clinically relevant time frame. It is usually carried out using an automated blood cell separator to ensure fluid balance and maintain a normal plasma volume. This may require the insertion of a femoral or jugular line to allow adequate blood flow. A one plasma volume exchange removes about 66% of an intravascular constituent and a two plasma volume exchange approximately 85%. Clinically significant bleeding is rare but a coagulation screen should be undertaken before surgery or organ biopsy is performed. Other risks include haematomas at venepuncture/line insertion sites, vasovagal episodes with fainting, fluid overload or under-replacement, and allergic or anaphylactic reactions due to plasma infusion. Thromboprophylaxis with low molecular weight heparin is recommended once the platelet count is >50109/L. Side effects from rapid infusion of red cells in citrate anticoagulant include perioral tingling and paraesthesia due to low ionised calcium level. Removal of white cells by automated apheresis may improve the clinical symptoms until chemotherapy takes effect. Possible indications include graft-versus-host disease after allogeneic haemopoietic stem cell transplantation and cutaneous T-cell lymphoma. Individuals vary in their choice and it is important to clearly establish the preference of each patient. Every patient has the right to be treated with respect and staff must be sensitive to their individual needs, acknowledging their values, beliefs and cultural background. Some patients, their family members or friends are very worried about the risks of blood transfusion, especially transfusion-transmitted infection, based on reports in the media or anecdotal experience. Others decline transfusion of certain blood products based on their religious beliefs. Provision of clear, balanced information on the risks and benefits of transfusion and, where appropriate, alternatives to transfusion, is a key component of obtaining informed consent (see Chapter 4). Many Witnesses accept the transfusion of derivatives of primary blood components such as albumin solutions, cryoprecipitate, clotting factor concentrates (including fibrinogen concentrate) and immunoglobulins. A copy of this should be placed in the patient record and the limitations on treatment made clear to all members of the clinical team. It is appropriate to have a frank, confidential discussion with the patient about the potential risks of their decision and the possible alternatives to transfusion, but the freely expressed wish of a competent adult must always be respected. The patient record should document the indication for transfusion and the patient should be informed of the transfusion when mental capacity is regained (and their future wishes should be respected). Where the parents or legal guardians of a child under 16 refuse blood transfusion (or other medical intervention) that, in the opinion of the treating clinician, is life-saving or essential for the well-being of the child, a Specific Issue Order (or national equivalent) can be rapidly obtained from a court. All hospitals should have policies that describe how to do this, without delay, 24 hours a day. Guidelines for Pre-Transfusion Compatibility Procedures in Blood Transfusion Laboratories.
