Health departments should have plans for responding to medicine stone music festival discount pristiq 50 mg overnight delivery reportable and nonreportable communicable diseases in child care programs and should provide training treatment guidelines order pristiq 100 mg line, written information symptoms ear infection pristiq 100 mg sale, and technical consultation to treatment yellow jacket sting buy generic pristiq 100 mg on-line child care programs when requested or alerted. Evaluation of the well-being of each child should be per formed by a trained staff member each day as the child enters the site and throughout the day as needed. Disease may occur as a result of contact with children with asymptomatic infection. In many situations, the expertise of the program’s health consultant and that of the responsible local and state public health authorities are helpful for determining the ben efts and risks of excluding children from their usual care program. Most minor illnesses do not constitute a reason for excluding a child from child care unless the illness prevents the child from participating in normal activities, as determined by the child care staff, or the illness requires a need for care that is greater than staff can Table 2. Medical evaluation for stools with blood or If stool frequency exceeds 2 or more stools mucus; exclusion until stools are contained above normal for that child or stools con in the diaper or when toilet-trained children taining blood or mucus no longer have accidents using the toilet and when stool frequency becomes less than 2 stools above that child’s normal frequency Oral lesions Exclusion if unable to contain drool or if unable to participate because of other symptoms or until child or staff member is considered to be noninfectious (lesions smaller or resolved). Examples of illnesses and conditions that do not necessitate exclusion include the following: • Common cold. Local health ordinances may differ with respect to number and timing of specimens. For most outbreaks of vaccine-preventable illnesses, unvaccinated children should be excluded until they are vaccinated. Infectious Diseases—Epidemiology and Control (Also see disease-specifc chapters in Section 3. Since administration of rotavirus vaccine was recommended routinely, disease and hospitalization for diarrhea attributable to rotavirus have decreased dramatically. Salmonella species, Clostridium diffcile, and Campylobacter species infrequently have been associated with outbreaks of disease in children in child care. Young children who are not toilet trained have an increased frequency of diarrhea and of fecal contamination of the environment. Enteropathogen spread is common in child care programs and is highest in infant and toddler areas, especially among attendees who are not toilet trained completely. Enteropathogens are spread by the fecal-oral route, either directly by person-to-person transmission or indirectly via fomites, environmental surfaces, and food, resulting in transmission of disease. The single most important procedure to minimize fecal-oral transmission is frequent hand hygiene measures combined with staff training and monitoring of staff implemen tation. A child in whom jaundice develops should not have contact with other children or staff until 7 days after symptom onset. Possible modes of spread of respiratory tract viruses include aerosols, respiratory droplets, and direct hand contact with contaminated secretions and fomites. Hand hygiene measures can decrease the incidence of acute respira tory tract disease among children in child care (see Recommendations for Inclusion and Exclusion, p 136). Extended close contact between children and staff exposed to an index case of meningococcal disease predisposes to secondary transmission. In the prevaccine era, the risk of primary invasive disease attributable to S pneumoniae among children in child care settings was increased compared with children not in child care settings. Secondary spread of S pneumoniae in child care centers has been reported, but the degree of risk of secondary spread in child care facilities is unknown. Prophylaxis for contacts after an occurrence of one or more cases of invasive S pneumoniae disease is not recommended. Use of S pneumoniae conjugate vaccine has decreased dramatically the incidence of both invasive disease and pneumonia among children and other age groups not targeted for vaccination and has decreased carriage of serotypes of S pneu moniae contained in the pneumococcal conjugate vaccine. Group A streptococcal infection among children in child care has been reported, including an association with varicella outbreaks. A child with proven group A strepto coccal infection should be excluded from classroom contact until 24 hours after initiation of antimicrobial therapy. Although outbreaks of streptococcal pharyngitis in these set tings have occurred, the risk of secondary transmission after a single case of mild or even severe invasive group A streptococcal infection remains low. Adults with symptoms compatible with tuberculosis should be evaluated for the disease as soon as possible. Child care providers with suspected or confrmed tuberculosis disease should be excluded from the child care facility and should not be allowed to care for chil dren until their evaluation is negative or chemotherapy has rendered them noninfectious (see Tuberculosis, p 736). Isolation or exclusion of immunocompetent people with parvovirus B19 infection in child care settings is unwarranted, because little or no virus is present in respiratory tract secretions at the time of occurrence of the rash of erythema infectio sum. This is based on the equivalent risk of acquisition of parvo virus B19 from a community source not affliated with the child care facility. Immunized children with breakthrough varicella with only maculopapular lesions can return to child care or school if no new lesions have appeared within a 24-hour period. All staff members and parents should be notifed when a case of varicella occurs; they should be informed about the greater likelihood of serious infec tion in susceptible adults and adolescents and in susceptible immunocompromised people in addition to the potential for fetal sequelae if infection occurs during the pregnancy of a susceptible woman. Susceptible child care staff members who are pregnant and exposed to children with varicella should be referred promptly to a qualifed physician or other health care professional for counseling and management. Therefore, use of standard precautions and hand hygiene are the optimal methods of prevention of transmission of infection. All child care providers should receive regular training on how to prevent transmission of bloodborne infections and how to respond should an exposure occur ( Indirect transmission through environmental contamination with blood or saliva is possible. This occurrence has not been documented in a child care setting in the United States. Because saliva contains much less virus than does blood, the potential infectivity of saliva is low. Serologic testing generally is not warranted for the biting child or the recipient of the bite, but each situation should be evaluated individually. For example, immunodefcient children exposed to measles or varicella should receive postexposure immunoprophylaxis as soon as possible (see Measles, p 489, and Varicella-Zoster Infections, p 774). Children who have not received recommended age-appropriate immunizations before enrollment should be immunized as soon as possible, and the series should be completed according to Fig 1. These children place other children at risk of contracting a vaccine-preventable disease. Child care providers are expected to render frst aid, which may expose them to blood. All adults who work in child care facilities should receive a one-time dose of Tdap (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis) vaccine regardless of how recently they received their last dose of Td for booster immunization against tetanus, diphtheria, and pertussis. General Practices the following practices are recommended to decrease transmission of infectious agents in a child care setting: • Each child care facility should have written policies for managing child and provider illness in child care. Disposable diapers with absorbent gelling material or carboxymethylcellulose or single-unit reusable systems with an inner cotton lining attached to an outer waterproof covering that are changed as a unit should be used. These sinks should be washed and disinfected at least daily and should not be used for food preparation. Handwashing sinks should not be used for rinsing soiled clothing or for cleaning potty chairs. Children should have access to height-appropriate sinks, soap dispensers, and disposable paper towels. Children should not have independent access to alcohol-based hand sanitizing gels or use them without adult supervision, because they are fammable and toxic if ingested because of their high alcohol content. Alcohol-based sanitizing gels should be limited to areas where there are no sinks. In general, routine housekeeping procedures using a freshly prepared solution of com mercially available cleaner (eg, detergents, disinfectant detergents, or chemical ger micides) compatible with most surfaces are satisfactory for cleaning spills of vomitus, urine, and feces. For spills of blood or blood-containing body fuids and of wound and tissue exudates, the material should be removed using gloves to avoid contamination of hands, and the area then should be disinfected using a freshly prepared solution of a 1:10 dilution of household bleach applied for at least 2 minutes and wiped with a dis posable cloth after the minimum contact time. Crib mattresses should have a nonporous easy-to-wipe surface and should be cleaned and sanitized when soiled or wet. Sleeping cots should be stored so that contact with the sleeping surface of another mat does not occur. Bedding (sheets and blankets) should be assigned to each child and cleaned and sanitized when soiled or wet. Because of their frequent exposure to feces and children with enteric diseases, staff members whose primary function is the preparation of food should not change diapers.

A case of the milk-alkali syndrome with a small amount of milk and magnesium oxide ingestion -the contribution of sustained metabolic alkalosis induced by hypertonic dehydration. Free pantothenic acid and its sodium salt are chemically unstable, and therefore the usual pharmacological preparation is the calcium salt (calcium pantothenate). The alcohol, panthenol, is a synthetic form which can be oxidised in vivo to pantothenic acid. It is included in the list of substances that may be used in the manufacture of foods for particular nutritional uses and in food supplements (the legal measure on food supplements is expected to be adopted in the immediate future). Calcium pantothenate, commercially available as the D-isomer or D,L-racemate, is stable in neutral solution, and destroyed by heat, and at alkaline or acid pH. In most dietary sources, and in biological tissues, pantothenic acid is present as coenzyme A and 4’-phosphopantetheine. This vitamin serves therefore as a cofactor in acyl-group activation and transfer in fatty acid and carbohydrate metabolism, as well as in a wide range of (other) acylation reactions (see Fox, 1984 and Plesofsky-Vig, 1996 for reviews). Pantothenic acid is widely distributed among foods, especially high concentrations are found in yeast and organ meat (liver, kidney), but eggs, milk, whole grain cereals and vegetables. In most foods it is present in bound form (as CoA), requiring enzymatic treatment for analysis of total contents. Ingested pantothenic acid is first hydrolysed to pantotheine and subsequently to free pantothenic acid by pantotheinase in the intestinal lumen. Although in earlier studies simple diffusion was reported to be the main transport system, there is now ample evidence that transport is effected in mammals through a saturable, sodium dependent transport system in the jejunum (Fenstermacher and Rose, 1986; Stein and Diamonds, 1989). The intestinal flora can produce pantothenic acid and animals practising coprophagy such as, rats and mice, can use faeces as a “dietary” source. In one study (Tarr et al, 1981) availability of pantothenate from an average American diet was assessed by comparing urinary excretion levels after controlled feeding (during 5 weeks) of an average American diet, containing 11. An average “relative” bioavailability of 50% (range: 40-61%; n=6) was calculated, assuming 100% availability from the synthetic form. About 60% of an oral dose of 10 and 100 mg/day, respectively, was excreted as intact pantothenic acid (Fry et al, 1976). Urinary excretion (normal range between 2-7 mg [9 32 mol]/day) reflects dietary intake, although a wide range of individual variation has been noted. Symptoms reported from an experimentally induced deficiency in humans using the antagonist -methylpantothenate in combination with a pantothenic acid deficient diet, include non specific symptoms such as headache, fatigue, insomnia and paresthesia of hands and feet. In animals diet-induced deficiency symptoms are hypertrophy of the adrenal cortex and increased resistance to viral infections in rats; hypoglycaemia, gastrointestinal symptoms and convulsions in dogs, and dermatitis and poor feathering in chickens. For Ireland mean intakes from all sources (food and supplements) were reported as 6. Following repeated oral dosing in rats (50-200 mg/day for 190 days), in dogs (50 mg/kg bw/day for 6 months), and in monkeys (1 g/day; 250-400 mg/kg bw/day for 6 months) no toxic effects were reported (Unna and Greslin, 1941). According to the “Cosmetic ingredient review” (1987) on panthenol and pantothenic acid no teratogenic or foetotoxic effects are known for rats fed calcium pantothenate before mating and throughout gestation. No abnormal chemical, histochemical and histological abnormalities were observed in the liver, adrenal, duodenum and tibia of the young rats at birth, born from females receiving 100 g or 1 mg calcium pantothenate daily during pregnancy (Everson et al, 1954; Chung et al, 1954). In the offspring of the group of rats treated with 50 mg/day, which were fed with the same daily dose as soon as they were weaned, a normal development was observed and weight gain comparable to the control group (Unna and Greslin, 1941). No toxicological effects have been reported for D and D,L-panthenol in subchronic oral toxicity studies in rats with dosages between 20-200 mg/day for 90 days; and with 2 mg/day for 6 months (studies cited in the “Cosmetic ingredient review”, 1987) 3. Data from studies in humans No data have been reported on pantothenic acid or panthenol toxicity in humans. A Medline and Toxline search from 1966 on did not reveal any report on adverse effects after oral intake of pantothenic acid or panthenol. High dosages were used in a placebo-controlled, double-blind trial on the potential beneficial effect of pantothenic acid in treatment of patients with arthritic symptoms (General Practitioner Research Group, 1980). In this study 94 patients were treated for 8 weeks with dosages of calcium pantothenate, starting with 500 mg/day in the first two days, then 1 g/day for the next three days, 1. Whether this hepatotoxic effect was related to the high dose of pantothenic acid, or to the combination with the high doses of nicotinamide, vitamin C and pyridoxine, cannot be concluded from this study, and therefore, this study cannot be used in risk assessment of pantothenic acid. Occasional diarrhoea and water retention might occur at daily dose levels of 10-20 g/day, as found in studies on stress protection and prevention of greying of hair (studies mentioned in a review by Fox, 1984, and in a Cosmetic Ingredient review on the safety of panthenol and pantothenic acid, 1987). Average intakes in adults range between 3-12 mg/day, and this intake level is considered as adequate. Few data on distribution of intakes from dietary and supplement sources are available. Dietary reference intakes for thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, biotin, and choline. The North-South Ireland Food Consumption Survey, Food Safety Promotion Board, Dublin ( Niacin is not strictly speaking a vitamin because it is formed from the metabolism of tryptophan, and is not per se essential to the body, providing that there is an adequate supply of the essential amino acid tryptophan (Horwitt et al, 1981). The condition that is characteristic of a deficiency of both tryptophan and preformed niacin is pellagra, which was originally recognised in 1735 and is characterised by spinal pains, “magenta tongue”, digestive disturbances and subsequently erythema with drying and expurgation of the skin. Various nervous manifestations, such as spasms, ataxic paraplegia and mental disturbances occur in severe cases. The deficiency disease occurred in Italy, Southern France, Spain and in the southern states of the United States of America where over 170,000 cases were reported annually between 1910 and 1935. Short-term (3 weeks) niacin deficiency in the elderly may lead to an increase in serum triglycerides in some subjects (Ribaya-Mercado et al, 1997). Niacin is present in food largely as bound forms that require hydrolysis to release the free nicotinamide or nicotinic acid prior to absorption. There are negligible concentrations of free nicotinic acid in crops such as cereals. Boiling releases most of the total niacin present in sweet corn as nicotinamide (up to 55 mg/kg) but very little as nicotinic acid (<5 mg/kg) (Kodicek et al, 1974; Mason et al, 1973). The niacin in cereals such as wheat, barley and oats does not give free nicotinic acid or nicotinamide on cooking (Mason et al, 1973). Roasted coffee contains higher concentrations of free nicotinic acid (160-400 mg/kg) (Smith, 1963). In addition, the niacin in cereals is present as a glycoside of nicotinic acid, which undergoes limited hydrolysis in vivo and is essentially not absorbed from the gastrointestinal tract and is not bioavailable (Yu and Kies, 1993).

In this unit medications causing pancreatitis purchase 50mg pristiq, the patient’s level of consciousness medications given for bipolar disorder cheap pristiq 50mg line, airway medications for rheumatoid arthritis generic pristiq 100mg mastercard, breathing and circulation are observed carefully. Tem perature is also measured, since hypothermia and pyrexia have their own problems and need to be corrected. Hypothermia can lead to shivering, which increases oxygen consumption and can lead to hypoxaemia. The need for postoperative care is inuenced by the severity of underlying illness, the dura tion and complexity of the anaesthetic and surgical procedures, and the potential for postoper ative complications (Barash et al. The postoperative period is a vulnerable time when things can go wrong very quickly. The patient is handed over to the recovery unit staff by providing a concise summary of the patient’s pre-existing medical condition, surgical procedure performed (including drains, blad der catheters, etc. Details of anaesthetic, uids administered (including blood and blood products), analgesics, other drugs given. Clear instructions are given regarding any investigations that need to be under taken, such as blood glucose and haemoglobin. Trained personnel should monitor the patient for all the parameters mentioned above and ensure haemodynamic stabil ity, adequate oxygenation and normothermia. Any major problems should be rectied before discharging the patient to the ward by handing over to the ward nurse. Essential equipment Certain essential equipment should be readily available in the recovery area: Pain 21 the trolley on which the patient is transported to the recovery area should have a mechanism for a rapid, easy head-down tilt. Monitoring All patients should be monitored for pulse oximetry and blood pressure. Hypoventilation is an important cause of hypoxaemia and postoperative respiratory problems. If a bladder catheter is already in situ, blockage of the catheter must be ruled out; this is a common, but often overlooked, cause of postoperative restlessness. Untreated pain can lead to several problems that can be detrimental to the patient (Table 3. Pain can cause sympathetic stimulation, which in turn may result in tachycardia, hyperten sion, sweating, anxiety, poor compliance with treatment and hypoventilation. Pain after abdominal surgery can lead to splinting of the diaphragm, resulting in hypoventi lation, hypoxaemia and atelectasis of the lungs, and predispose to postoperative retention of pulmonary secretions and pneumonia (reduced ability to cough). Pain also causes the release of endogenous catecholamines, with cardiovascular sequelae. Central respiratory depression Residual inhalational or intravenous anaesthetic agents Strong analgesics, particularly opioids. Impaired mechanics of breathing Pain (particularly after abdominal surgery), leading to splinting of the diaphragm Residual effects of muscle relaxants Pneumothorax, haemothorax Obesity, leading to splinting of the diaphragm. In our recovery unit, pain is commonly scored on a visual analogue scale of 0 to 10, with 0 being no pain and 10 being the worst possible pain. The aim is to have a pain score of less than 4 before discharging the patient to the ward. Objective assessment includes observing the patient’s expression (grimacing, wincing), pur poseful movements towards the surgical site, and parameters such as heart rate (usually increases but occasionally decreases), blood pressure (increases) and respiratory rate (increases except when depressed due to opiates). Urinary retention and a full bladder are common causes of postoperative restlessness but are often overlooked. Gate theory of pain According to the gate control theory of Melzack and Wall (1965), the transmission of impulses conducting pain is regulated by a ‘gate’ and mediated through large afferent A bres that inhibit transmission of pain from other afferents. A continuous stream of afferent impulses closes the ‘gate’ and prevents more painful impulses from being transmitted. Opiate receptors are found in the brain and spinal cord (dorsal horn neurons and on the ter minals of the nociceptors within the dorsal horn). Endogenous peptides such as substance P can be nociceptive or can produce analgesics such as endorphins and encephalins (see below). Pain relief is assessed and administered appropriately (usually based on local protocols), postoperative nausea and vomiting are treated, the surgical wound (including drains, dressings, underwater seals, etc. It must be borne in mind that postoperative analgesia can start in the preoperative period. Preoperative administration For short procedures where postoperative pain is anticipated, particularly in the day surgery unit, analgesics such as paracetamol and diclofenac can be included as part of the premedication. This proves useful in the post operative period by reducing the requirements for postoperative analgesia. Local anaesthetics Local anaesthetics are generally administered intraoperatively or occasionally preoperatively, particularly for surgery undertaken under local anaesthesia. Simple local anaesthetic techniques include wound inltration, instillation at the operative site, eld blocks (for inguinal hernia), nerve blocks. Lidocaine is short-acting and in repeated doses is known to lead to tachyphylaxis (particu larly when used for epidural blocks). The safe dose of lidocaine is 3–4 mg/kg when used plain and up to 6 mg/kg when used with adrenaline (epinephrine). Hyperbaric solutions settle down into the most dependent part (since they are ‘heavy’), while hypobaric solutions tend to rise up to the non-dependent area. This is very important when calculating the amount of local anaesthetic that can be used safely for inltra tion. Care must be taken when injecting into areas with good blood ow, since more rapid absorp tion results in higher serum levels being attained more rapidly, increasing the likelihood of developing toxicity (see Chapter 17) – hence the mandatory precaution of aspirating the syringe before injecting local anaesthetics. Bupivacaine has systemic toxicity refractory to treatment when serum levels exceed thera peutic limits, particularly related to the heart. The quest for safer isomers of its racemic mix ture has led to the advent of two preparations that are believed to be safer, especially in rela tion to cardiac toxicity: ropivacaine and levobupivacaine use the safer, pharmaceutically isolated isomers of bupivacaine, greatly reducing the risk of cardiac toxicity and rendering them amenable to treatment if toxicity does occur. Epidural and spinal anaesthesia can be used as the sole technique for the operation. Epidural and spinal anaesthesia can also be used as an adjunct to general anaesthesia, partic ularly epidural analgesia coupled with general anaesthesia for major abdominal surgery. This helps to minimise the use of parenteral opiates, allows the patient an earlier return to con sciousness at the end of surgery, and provides better quality of analgesia with minimal depres sion of consciousness, better ventilatory mechanics, minimal or no respiratory depression and the ability to cough and breathe without pain. Potential side effects of epidural and spinal anaesthesia are hypotension, hindered ventila tion (particularly with respect to the contribution of abdominal and intercostal muscles) with higher levels of blockade, and occasionally decreased sensation, which can interfere with ambulation (seen only with higher concentrations of epidural local anaesthetics). It is more common to nd that the good pain relief actually aids and encourages ambulation. This is due to the denite risk of an epidural haematoma, which, although uncommon, is potentially dangerous and can lead to paraplegia if not treated urgently (usually surgically). Epidural analgesia is usually given by a continuous technique, using a clearly labelled custom built infusion pump (Figure 3. The epidural infusion consists of either local anaesthetic alone, or a combination of local anaesthetic and opiate. Opiates commonly used for spinal and epidural analgesia are fentanyl (2–4 g/mL for epidural), alfentanil (20–40 g/mL for epidural) and diamorphine (300–400 g for spinal). All are highly lipid-soluble, bind to the opiate receptors in the spinal cord and reduce the require ment of local anaesthetics. These opiates help not only by enhancing the analgesia provided and the duration of blockade but also by reducing the dose requirements and side effects. Since by this time the patient is usually on the ward, it could lead to potential problems. Therefore, morphine should be used with caution; alterna tively, diamorphine should be used instead. A potential problem of adding opiates to epidural infusions, particularly in abdominal sur gery, is the possibility of reduced gut motility. The device self-locks for a pro grammed period (usually 5 min) in order to prevent the patient from overdosing. Naloxone is a specic antagonist, but it must be remembered that administration of naloxone not only reverses the side effects such as respira tory depression but also reverses the analgesia, leading to pain. Fluid balance involves giving enough uids and giving uids appropriately based on the individual patient’s needs.

For instance, a sample giving a Catalyst One* result that is slightly below the Catalyst One analyzer’s normal range should give a laboratory result slightly below the laboratory’s normal range. Preface to Online Supplement Antibody identification and serologic problem solving involve much more than knowing how to perform the procedures. Antibody Identification: Art or Science steps in where hands-on practice struggles to go. Case studies that begin with a clinical scenario and initial test results guide the learner through a sequence of multiple choice questions that offer testing options and protocols for resolution. The difficulty of the cases ranges from basic to advanced, allowing use by multiple levels of students, residents, transfusion medicine fellows and practicing medical laboratory scientists (medical technolo gists). Autoantibodies or other situations involving positive autologous control tests or direct antiglobulin tests are not included. Advanced techniques for alloantibody identification such as the use of chemicals, inhibition, adsorption, and adsorption/elution are presented to challenge the learner who has mastered single alloantibody cases. Written by practicing serologists and educators, the processes in these cases represent practical and efficient paths to problem resolution. Working through the cases will supplement didactic learning in a variety of settings from formal edu cation programs to on-the-job instruction. Each case is designed as a stand-alone lesson enabling the instructor/supervisor to use just those cases most appropriate for their learner. Through cases that present serologic problem solving as a series of logical and systematic steps, the authors hope to demonstrate that the art of antibody identification, as well as the science, can be a learned skill. Which of the following antibody specificities would be a likely hypothesis based on the results of the antibody detection test and patient typing results If this laboratory had a “3 + 3 rule” for confirmation of antibody specificity, how many additional cells must be tested to complete this identification She has had several other surgeries, some requiring blood transfusion, but no procedures in the last 3 years. A sample was received in the blood bank with orders for type and crossmatch of 2 units of Red Blood Cells. Which of the following antibody combinations could account for all of the reactions noted in Panel 1 In order to strengthen the hypothesis of anti-C plus anti-Fy, the medical laboratory scientist repeated the antibody identification panel using manufacturer-supplied ficin-treated cells. All previously reactive cells from the untreated panel would be more strongly reactive. All previously reactive cells from the untreated panel would be more weakly reactive or not reactive at all. Anti-C reactions would be at the same or greater strength and anti-Fy reactions would be weakened or abolished. Anti-Fy reactions would be at the same or greater strength and anti-C reactions would be weakened or abolished. He has no history of significant medical problems, with the exception of injuries received during his service in the military. A sample for “type and screen” was sent to the laboratory on the morning of the procedure. Given the results of the antibody detection test, what hypothesis can be developed Given the initial serologic findings, what should the medical laboratory scientist do next Based on the antibody identification test results and the laboratory rule-out criteria listed above, which of the following cells would rule out anti-c Although the phenotype is not represented on this antibody identification panel, it is fairly common in the population. The phenotype is rare due to the high prevalence of the k antigen in the population. It is the policy of this laboratory to identify two antigen-negative units for patients with antibodies, even if the original order was for type and screen only. The broken hip was sustained in a fall while she was visiting her daughter in another city. Because she is not being treated by her own physi cian, complete medical records are not available. Her daughter reports, however, that her mother had been relatively healthy during her life and has not been admitted to a hospital except for childbirth. Which of the following alloantibodies can be excluded on the basis of the antibody detection test results Which of the following tests could have been performed to determine whether an autoantibody might be present in the sample Which of the following conclusions is supported by the reactions noted in the antibody identification panel The medical laboratory scientist has hypothesized that the patient has anti-c and has begun the process b a of selecting cells to rule out other antibody specificities including anti-Le, anti-S, and anti-Jk. Which of a the cells in the table below should the medical laboratory scientist choose to rule out anti-Jk This is her first pregnancy and she has no history of transfusion or transplantation. Specimens have been drawn for laboratory testing, including an order for a type and antibody detection test (results below). The patient’s nurse said that transfusions would not be needed, but the patient’s obstetrician is interested in knowing the antibody identification. The technologist tested an additional anti body identification panel using a saline tube technique. What is the advantage of using tube testing techniques in addition to gel in the investigation of this case Tube testing may provide additional information regarding the phase of reactivity. Which of the following antibodies that were not initially ruled out with Panel 1 can be ruled out by Panel 2 He has a number of previous hospital admissions with no record of clini cally significant antibodies. Which of the following tests should be performed to resolve/complete the antibody identification in this case Now that the medical laboratory scientist has determined that the anti-M did not show reactivity at 37 C, he/she repeated the reverse typing using a prewarmed technique. Given the results of the antibody detection and identification testing, what type of crossmatch could avoid the reactivity of the anti-M His medical history is unremarkable and he reports that he is currently in good health. He has no history of previous serologic problems but does report that he had received blood trans fusions after an injury during the Vietnam War. Given the results of the antibody detection test, what hypothesis can be proposed Based on the results of the antibody detection and identification tests, which of the following appears to be present Which antibody specificity(ies) has a perfect “pattern of fit” for the reactions seen According to facility policy, what alloantibody specificities are ruled out using the results of the antibody identification panel Which of the following additional tests could be used to potentially rule out these antibody specificities and could be performed in a reasonable time frame in most routine transfusion services Keep in mind that weakly reactive antibodies may not be reac tive with all antigen-positive cells.
