Multiple reasons may account for these disturbances in the function of its target organs: variations (Table 5).

In this tive or absolute deficiency of vitamin D or its condition, there is also increased bone formation active metabolites and/or resistance to their ac as evidenced by increased amounts of osteoid. This osteitis fibrosa is a high-turnover bone dis Vitamin D may affect mineralization through ease. It is not evident whether a fective mineralization of osteoid leads to rickets deficiency in one or more of the vitamin D in children and osteomalacia in adults. Osteomalacia may be more frequently excess osteoid does not necessarily mean osteo encountered in uremic patients with low blood malacia. These derangements result in a cline labeling can differentiate between these 2 defect in collagen cross-linking and may affect possibilities and is thus critical for the diagnosis bone mineralization. The skeleton in osteomalacia is lagen metabolism are most likely due to vitamin weakened, and patients with this bone disease Ddeficiency. The magnesium content of the the most important factor in the development of bones of these patients is increased, and this may osteomalacia is aluminum overload. This type of bone cium intake is increased or if dialysate calcium is disease has been called low-turnover bone dis high. Osteoscle seen in dialysis patients who have a large content rosis appears as increased bone density in roent of aluminum in bone and in whom the aluminum genographic studies. Histologically, osteosclero is localized in the mineralization front (ie, the sis is most likely due to accumulation of limit between osteoid and calcified tissue). With unmineralized trabecular bone with an increase a decrease in the use of aluminum-containing in total bone mass. Because osteosclerosis af compounds for the control of hyperphosphatemia, fects trabecular bone, it is most evident in the the incidence and prevalence of osteomalacia vertebrae, pelvis, ribs, clavicles, and metaphyses have been decreasing. Increased burden of iron, of long bones, which are made predominantly of alone or in combination with aluminum, can cancellous (trabecular) bone. Certain experimental and clini failure patients before and after treatment with cal evidence suggests that osteosclerosis could peritoneal dialysis or hemodialysis. Immobiliza characterized by a defect in bone matrix forma tion, calcium deficiency per se, and chronic pro tion and mineralization, increased osteoid thick tein depletion may be causes of the osteoporotic ness, and a decrease in the number of both component of kidney osteodystrophy.

Certain factor(s) that may act locally als once the labile calcium carbonate component to inhibit calcification and are present in the of bone is lost. Although there may be a slight blood of these patients may possibly be removed improvement in negative calcium balance follow during hemodialysis. Local tissue injury may ing treatment of the chronic acidosis with alkali, also predispose to calcification when the calcium a positive balance for calcium usually does not phosphorus product is normal or only slightly occur, and hypocalcemia, bone pain, and radio elevated. More certain proteins involved in prevention of calcifi over, there is no convincing evidence suggesting cation has been demonstrated in macrophages that chronic acidosis can cause defective mineral and smooth muscle cells of blood vessel walls. An increase in the calcium-phosphorus vascular calcification seen in patients with kid product in the extracellular fluid is probably the ney failure. The inci the chemical nature of soft-tissue calcifica dence of soft-tissue calcification is high when the tion may vary in different tissues. Thus, the calcium-phosphorus product (each in mg/dL) calcification found in nonvisceral tissue (periar exceeds 70, while soft-tissue calcification is infre ticular and vascular calcification) consists of quently noted when the calcium-phosphorus prod hydroxyapatite, with a molar Ca:Mg:P ratio simi uct is below 50.

These observations suggest that the mechanisms Alkalemia, which often occurs after hemodialy responsible for the calcification of various tis sis, may persist during the interdialytic period sues in uremic patients may be different.

The lumen of the apparent each time a new calcium deposition vessel is usually not involved. More commonly, con fication may first be seen in the dorsalis pedis as junctival calcium deposits are asymptomatic and a ring or a tube as it descends between the first are seen as white plaques or as small punctate and second metatarsals. Calcification can also deposits on the lateral or medial segment of the occur in atherosclerotic plaques in the intima of bulbar conjunctiva. Also, calcium deposits may large vessels whose radiographic appearance is occur within the cornea at the lateral or medial that of discrete, irregular densities. It is possible segments of the limbus, the so-called band kera that uremic patients are more prone to this type topathy.

In a patients with calcium deposition in the myocar series of 135 patients published in 1977, the dium or in and around the conduction system of incidence of vascular calcification increased from the heart or the mitral annulus.

Increased serum levels of a parathyroid hormone-like protein in malignancy-associated hypercalcemia. Studies of the mechanism by which phosphate infusion lowers serum calcium concentration. We intend to draft a practical guideline, focusing on operationalized recommendations deemed to be useful in the daily management of patients. This systematic search found 1100 articles, which was reduced to 312 based on title and abstract. The working group assessed these for eligibility in more detail,and32full-textarticleswereassessed. Data on quality of life and the risk of complications have just started to emerge, and clinical trials on how to optimize therapy are essentially non-existent. This guideline is therefore mainly based on how patients are managed in clinical practice, as reported in small case series and based on the experiences of the authors. See further We formally graded only the evidence underlying rec section ‘Summary of methods used for guideline ommendations for therapeutic choices and target calcium development’. Monitoring of the patient when implementing different therapeutic efforts, aiming to achieve the therapeutic goals. Predisposing factors involved are syndrome (7)) or as an isolated endocrinopathy young age, female gender, Graves’ disease, lymphadenect (see Table 1). Impaired renal function has been associated secretion immediately after surgery resulting in hypocal with the age of the patient, duration of the disease and caemia (14, 15). Normal to high need to mineralize the foetal skeleton and to provide this calcium levels at 1 month after thyroidectomy appears to essential mineral to the breast milk to sustain postnatal increase the chance of parathyroid gland recovery.

In effects on the kidney prompt urinary calcium levels to fall support of these issues, large cohort studies from Denmark during lactation. Also suggested are 24-h urinary calcium excretion feeding and hypotonia) may result (27, 29, 30, 31, 32, 33, to be measured yearly or every other year. Conversely, maternal overtreatment resulting in hypercalcaemia can suppress foetal parathyroid 2. In recent years, a number of studies have been published showing that normocalcaemia can be main 2. The treatment should aim to maintain serum calcium to its continuous episodic endogenous pattern of levels in the low normal range, serum phosphate within the secretion. Hyperphosphatae ations in serum calcium levels compared with injections mia should be addressed by decreasing dietary phosphate once-a-day (43). Magnesium-depleted patients should calcium significantly compared with twice-a-day injection be replete with this mineral. It is interest in calcium metabolism might also find the unknown whether long-term therapy also may cause guideline useful, as might our patients. According to a predefined schedule, daily Congress of Endocrinology, 18th May 2015 in Dublin. Aims a daily dose of 25 mg or up-titrated to a daily injection of the overall purpose of this guideline is to provide either 75 or 100 mg. Guideline working group systematic approach for synthesizing evidence and grad this guideline was developed and solely sponsored by the ing of recommendations (45). The other members: C Marcocci, the first methodological step for the guideline develop L Rejnmark and D M Shoback (endocrinologists), W van ment group is to define the clinical question(s) to be Biesen (nephrologist) and A Sitges-Serra (endocrine addressed in the guideline (see section ‘Clinical question, surgeon) were all approved by the Committee. These clinical working group had two in-person meetings (January and questionsareformulatedinsuchwaysthattheiranswerscan December 2014) and communicated by phone and email. Prior to the process, all participants Whereas the question, is hydrochlorothiazide better than completed conflict of interest forms. Importantly, the clinical is judged as not important or if a management strategy questions should be specific in terms of populations. Another available evidence, the guideline development group rated consideration is that you cannot abstain from recommen clinical outcomes either as critical, important but non dations when there is no evidence, as treatment decisions critical, and not important (46), see section ‘Clinical need to be made any way. To optimize transparency, all recommen relevant articles, synthesis of the evidence was made in dations provided are accompanied by text explaining why two directions: i) estimation of an average effect for specific recommendations were made. Clinical question, eligibility criteria and endpoint is provided as a summary rating (using four categories: definition high, moderate, low and very low) across studies for each outcome, as it may be that quality differs for different the clinical question on which the literature search was outcomes. The recommendations are worded as recommend (strong recommendation) and suggest (weak the following outcomes were rated by the guideline recommendation). The meaning of a strong recommen working group as critical: dation can be stated as follows: reasonably informed i) Mortality. Only for recommen defined as symptoms or episodes of nephrolithiasis dations regarding treatment, did we aim for formal or nephrocalcinosis. Only quality evidence may not directly translate into a strong articles in Dutch, English, German and French were Sample sizes were too small and follow-up too short well as the relevant interventions and outcome measures. Articles identified by the working group as relevant were used to optimize the search strategy. Articles Cramps, tetany and seizures " Occurrence of cramps, found by ‘snowballing’ were also considered. For rence of these conditions under different treatment the final recommendations, other literature (basic litera regimens. Conclusions from scientific literature and reported in various ways on serum calcium levels. In directions for further research general, calcium levels within the target range can be achieved with different treatment (combinations), and the 4. Summary and interpretation of the main findings risk of severe hypo or hypercalcaemia is low. Study results in perspective definition (see section ‘Clinical question, eligibility Very little evidence is available on how best to treat criteria and endpoint definition’). Data on QoL and the risk of complications have had a sample size of O100 patients. Also no studies are available that relate target calcium levels to clinically relevant endpoints. Study endpoints Thus, we do not know what the optimal calcium target Mortality " Only one study reported data on mortality is. No deaths were reported in this randomized study to formulate recommendations based on strict evidence. If the patient’s well being is improved by titrating treatment in such a manner Reasoning " Hypocalcaemia is defined as an ionized or that serum calcium levels are in the upper part of the albumin adjusted serum total calcium level below the reference interval, this may be accepted as no data exist on lower limit of the reference interval. Measurements of whether relatively high normal serum calcium levels are of ionized or total calcium mostly reflect local traditions, specific harm to patients. It is generally assumed that this is exists on long-term benefits (or harms) of achieving these related to high serum phosphate levels and an increased therapeutic goals. Accordingly, patients cannot be ensured serum calcium–phosphate product, which is why it seems long-term beneficial effects, when accepting potential side reasonable to aim at keeping phosphate levels within the effects to drug treatment or (troublesome) changes in normal range (59). Thus, we consider it inappropriate management, if therapeutic efforts have immediate R. Moreover, low magnesium levels may monitoring of patients at regular time intervals. Accordingly, calcium levels may, however, change and complications it seems reasonable to aim at keeping serum magnesium may emerge at any time, with or without any apparent levels within the reference range. Thus, we find it of importance to empower patients with knowledge of symptoms and co-morbidities and drugs R. If a patient is diagnosed with one of the have neuromuscular complaints (4, 38, 53). To ensure that diseases or initiates treatment with one of the drugs, this symptoms are not caused by low vitamin D levels, it seems may necessitate changes in the medical treatment of reasonable to ensure an adequate vitamin D status (55).

By measuring the diameter of the lesion (assuming that it is approximately spherical) and calculating its volume with the formula: volume ¼ 4=3pr3 where p is the constant pi and r is the radius of the lesion treatment yeast diaper rash generic 12.5mg esidrix amex. After the volume is calculated on two separate occasions, doubling time can be derived from a plot of volume versus time. A calculation that describes the effect of size and other factors on slowing of tumor growth. Doubling time calculation is a rough estimate because it assumes simple growth kinetics and the absence of other factors that affect tumor growth. However, tumor cell populations exhibit a reduction in growth rate with increasing size because they receive less blood supply to the center of the tumor as the mass grows, and the Gompertz equation accounts for this effect. The vast majority of infections originate from the patient’s own endogenous flora. In investigating the cause of an infection, cultures should include blood, urine, sputum, and if appropriate to the patient’s clinical status, stool, pleural fluid, or peritoneal fluid. Renal cell carcinoma and multiple myeloma tend to be purely lytic, prostate carcinoma tends to be mostly blastic, and other bone lesions are mixed. Lytic bone lesions are often associated with hypercalcemia, unlike blastic metastases. A dull, aching discomfort that is worse at night and may improve with physical activity. Most types of tumors can metastasize to the lungs; therefore, the more common the tumor, the more common the lung metastases. Tumors that spread via the bloodstream, such as sarcomas, renal cell carcinoma, and colon cancer, tend to produce nodular lung lesions. Those that spread via lymphatic routes, such as cancers of the breast, lung, pancreas, stomach, and liver, may manifest a pattern of lymphangitic spread. Headache occurs in up to 50% of patients with intracranial metastases and is classically described as occurring early in the morning, disappearing or decreasing after arising, and associated with nausea and/or projectile vomiting. Other symptoms include focal signs such as unilateral weakness, numbness, seizures, or cranial nerve abnormalities. By decreasing intracranial pressure with steroids, followed by definitive therapy. Surgery is recommended for patients with single intracranial lesions if technically possible, whereas radiation therapy is generally administered for multiple lesions. Chemotherapy may also be used, but the results are not as reliable as the other modalities owing to the difficulty of chemotherapy agents penetrating the blood-brain barrier. Frequently similar to the symptoms of heart failure with dyspnea, peripheral edema, and an enlarged heart on chest x-ray. However, the dyspnea is often out of proportion to the degree of pulmonary congestion seen on the x-ray. Kussmaul’s sign, or jugulovenous distention with inspiration, and pulsus paradoxus of > 10 mmHg with distant heart sounds are clues to the presence of a pericardial effusion. Treatment depends on the patient’s condition but should include drainage of the fluid for diagnostic as well as therapeutic reasons. A nonsurgical approach is preferred, with catheter drainage followed by sclerosis of the pericardium, sometimes with a sclerosing agent such as doxycycline. Other approaches include subxiphoid pericardiectomy, balloon pericardiectomy, pericardial window, and pericardial stripping for patients with prolonged life expectancy. Other symptoms include lower extremity weakness, bowel or bladder incontinence, or increased deep tendon reflexes in the lower extremities. Once neurologic symptoms appear, the nerve damage may be irreversible; therefore, early diagnosis of cord compression is essential. Initially by decreasing spinal cord swelling and pain with high-dose steroids and adequate pain medication. Definitive treatment with surgery or radiation therapy must be carried out emergently to prevent irreversible neurologic deterioration. This paraneoplastic syndrome is also known as “marantic endocarditis” and has also been described in other types of cancers. Usually the appearance of embolic peripheral or cerebral vascular events causing arterial insufficiency, encephalopathy, or focal neurologic defects. The emboli originate from sterile, verrucous, fibrin-platelet vegetations that accumulate on the heart valves, likely due to a hypercoagulable state from malignancy. However, echocardiograms may be negative, and the diagnosis is usually made postmortem. Treatment with anticoagulants or antiplatelet drugs has been tried with little success. Electrolyte and metabolic disturbances such as hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia that can result in renal failure, arrhythmias, and seizures. These disturbances occur when rapidly growing tumors are effectively treated with chemotherapy and breakdown products of dying tumor cells are released in large amounts into the bloodstream. The complication is seen within hours to days after treatment of malignancies such as acute leukemia and high-grade lymphomas such as Burkitt’s lymphoma. With allopurinol and supportive measures for renal failure such as vigorous hydration, dialysis if necessary, and appropriate treatment of electrolyte disorders. Rasburicase (recombinant urate oxidase) can be administered when uric acid levels are not lowered by standard approaches. Prophylactic treatment with aggressive hydration and allopurinol can prevent this serious complication and should always be given before chemotherapy in malignancies with high proliferative index. Pain medications are to be administered in a stepped approach according to the intensity and pathophysiology of symptoms and individual requirements. Patients with moderate-to-severe pain generally require an opioid agent such as codeine or oxycodone; severe pain requires a stronger opioid such as morphine. Neurol Clin 16:449–481, 1998; and Didelot A, Honnorat J: Update on paraneoplastic neurological syndromes. The incidence is increased and nearly equal in men and women, in China, Africa, Russia, Japan, Scotland, and the Caspian region of Iran. In the United States, African American men living in urban areas are at increased risk. Adenocarcinoma of the esophagus is now more prevalent than squamous cell carcinoma in the United States and Western Europe, with most tumors located in the distal esophagus and esophagogastric junction. Fewer than half of patients appear to be operable at the time of presentation, and of these, only one half to two thirds have tumors that are completely resectable. Nonsurgical patients are treated with combined chemoradiotherapy or palliative measures if their performance status is too poor for active therapy. Some evidence indicates that survival in patients with adenocarcinoma of the esophagus is improved with preoperative combined chemotherapy and radiotherapy. Ongoing trials are investigating whether the outcome with chemoradiotherapy is equivalent to that of surgery. Differences between mutations associated with the intestinal and diffuse types of gastric cancers may account for their different natural histories. Describe the diagnostic and staging evaluation for patients suspected of having pancreatic cancer. How is the diagnosis of pancreatic cancer confirmed and the extent of metastatic disease evaluated? Additional staging includes routine laboratory studies, chest x-ray, and other tests as directed by the history and physical. Which environmental factors are thought to be related to the development of colon cancer? A syndrome characterized by the occurrence of thousands of adenomatous polyps throughout the large bowel. If left untreated, cancer will develop in all patients with this syndrome, usually before the age of 40. The most common hereditary colon cancer syndrome that is also associated with extracolonic cancers such as endometrial, ovarian, pancreatic, gastric, renal, hepatic, and small bowel. If elevated, it should be retested 30–45 days after complete resection of the cancer.

Generalized abscesses, emaciation, and jaundiced organs or tissues are reasons for condemnation. Lymphadenopathy indicates disease or inflammation in the area drained by the enlarged nodes. Local adenopathy may indicate a local process only (condemn only affected area), while more extensive adenopathy probably implies widespread disease process. Palpate and examine lymph nodes of the head and neck for gross swellings or lesions. Inspect and palpate all surfaces for abnormalities, discoloration, masses and parasites; examine the heart, lungs and diaphragm as well. Slice open organs and examine for parasites, infection or disease states such as tumors. Joints and Skeletal Muscles: Bruises and localized lesions may be removed and the rest of the carcass consumed. For arthritic and swollen joints, remove affected limb, and then consume carcass if arthritis is not due to systemic disease such as septicemia or caseous (cheese-like) lymphadenitis. Neoplasia, Tumors or Abnormal Growths: Condemn organ system and/or carcass if spread throughout. Off Odors: Condemn carcass with strong odors of urine, ketones (a fruity smell) or pungent sexual odors. When excess food must be stored and preserved for future use, follow these rules: preserve and store only wholesome foods that were initially safe to eat; use only potable water and spices when curing or preserving food; cold storage/freezing is the best method if available; periodic re-examination of stored products is essential to ensure wholesomeness and prevent consumption of contaminated or deteriorated food (moldy, infested, stale). What You Need: Knife, meat, potable water, salt, 1% salt solution (brine), string, green hardwoods, building, saltpeter (potassium nitrate), spices, fire source, hay, salt box and/or brine pan, boiling pot. Curing Although it may be done alone, curing should be done in association with smoking. Raw meat should be clean, edible and sliced against the grain into manageable pieces (step one of beef prep for smoking). If using brine, then the solution should be 1% salt (one pound of salt to 9 pints water). Use clean plastic, glass or earthenware containers, not wood or metal containers to hold brine solutions. Smoking There are several acceptable procedures for smoking meat and different step by step processes. Smokehouse Use any well-sealed building with a vented roof and a floor that can have a fire pit. Let fire burn down to coals and then stoke it with green wood to produce “cold smoke” (less than 85°F). Allow even smoking and avoid contact spoilage by ensuring that all meat hangs free. Time Smoke meat for 4-5 days, depending on size of house, size and number of pieces of meat to smoke. The hole for string should be centralized enough to prevent meat ripping during smoking. Hang meat and prepare smoking record (see preservation records and recommendations below). Smoked meat should be edible for up to one year depending on climate, condition of meat prior to smoking and insect and rodent control. Meat may also be dried over slow coals or sun-dried (sprinkle with pepper and hang about 20 ft into air above insect line). Pemmican Two basic ingredients: lean meat that is not salt cured and rendered fat. Prepare a casing, such as intestine, by cleaning (strip out contents and boil) and tying one end. The fat will separate into tallow, the liquefied oil from fat, and (cracklings), the fat residue. For pickling, mix 50 pounds of salt and 5 pounds of saltpeter with 20 gallons of water. Canning and Other Methods these procedures are effective but require resources and equipment not readily available in a field environment. Records should have the following information at a minimum: meat type, date, source of meat, weight and cut of meat, total time cured (preserved), wood used and/or type and amount of salt/seasoning/brine used. What Not To Do: Do not use meat that is unfit for consumption based on ante or postmortem exams. What You Need: Rope, twitch, nose lead, stethoscope, pen, paper, leather gloves, exam gloves, light source, rectal thermometer (large animal style preferred) What To Do: 1. Restraint: Allow owner and/or indigenous persons to handle and restrain the animals as much as possible. This is probably the most difficult part of the examination and may be the most dangerous. Halter Fasten a rope loop around the animal’s neck with a bowline knot to make a temporary rope halter. Pull a bight of the standing end through the loop from rear to front and place over the animal’s nose. A twitch is a small loop of rope or smooth chain twisted around the upper lip of the horse to divert attention from work being done elsewhere on the horse. Twist the rope or chain with a stick or rod to tighten the twitch, but avoid circulatory compromise. Casting a cow (Burley Method) You will need approximately 40 ft of rope, with the center of the rope over the withers and wrapped as shown in the diagram. While maintaining control of the head, pull tightly on the ends of the rope and the cow will fall. To tie the rear legs, keep both ropes taut and slide the uppermost rope along the undersurface of the rear leg to the fetlock. Then carry the end around the leg and above the hock, across the cannon bone and back around the fetlock. Restraining the Legs Tie all four feet together to restrain the animal after it has been cast (dropped). Tie the other legs to this one alternately, first a front leg, then a 5-129 5-130 rear one and repeat. Cattle Tail Restraint Bend the tail of the cow toward the side or back of the animal to distract the cow. Examination: Once an animal is sufficiently and securely restrained, begin the physical exam. Remember: the diseases and injuries of animals can be similar to those in humans, but seek advice from appropriate veterinary providers or the Merck Veterinary Manual if available. One can only diagnose and treat based on his level of knowledge and understanding of veterinary medicine. Many zoonoses are threats in the field environment and precautions need to be taken to minimize them. Review the Preventive Medicine chapter and individual infectious disease sections for specifics on zoonoses and how to prevent them. Abuse is unethical, unnecessary and may jeopardize the relationship with native personnel. When to intervene is dependent on the state of parturition, the presentation of the fetus, duration of labor and history of underlying disease processes. This outline will provide only the basics of “normal” parturition and guidelines for observation and minimal intervention. Subjective: Symptoms Prior to parturition a normal animal will walk with difficulty, often looking back at her flanks. The udder may swell and become distended with milk, the tailhead ligament will relax and the vulva may swell and begin to discharge mucus or fluid. Duration of labor varies considerably between species (15 minutes for horse; up to 7 hours for a pig litter), and is longer in animals giving birth for the first time. He/she may also be of assistance in controlling the animal and giving medical history. Animal will present with an enlarged abdomen and a drop in body temperature (1-2° below normal 12-24 hours before birth–see Physical Exam section of this chapter).

Relation of the rheumatic fever recurrence rate per streptococcal infection to preexisting clinical features of the patients. The teaching and practice of cardiac auscultation during internal medicine and cardiology training. The microbiol ogy laboratory plays an important role in ensuring that the documen tation of group A streptococcal infections is accurate. It does so by using scientific methods both to determine whether group A strepto cocci (Streptococcus pyogenes) are present on swabs from suspected streptococcal throat infections, and to measure streptococcal serum antibody titres for documenting previous infection. The conventional methods and procedures for serologically identifying group A strep tococcal infections are described elsewhere (3). Diagnosis of streptococcal infection Group A streptococci can be subdivided into more than 130 distinct types, based upon a characterization of the M protein of the cell wall, opacity factors antigens produced by the organism, and by molecular sequencing of the emm gene that codes for M protein. A less-specific method is to determine the T-antigen pattern, but similar T antigens may be shared by several different M types (4–7). Nevertheless, all group A streptococci produce hemolysis on blood agar, and have an optimum growth temperature in the range 35–37°C. The gold standard for detecting Streptococcus pyogenes remains a throat swab cultured on blood agar, although it takes 24–48 hours to produce a result, with the consequent delay in starting antibiotic therapy. If possible, throat swabs should be examined for all patients with clinically suspected streptococcal upper respiratory tract infec tion. The correct procedure for taking a throat swab is to directly observe the tonsillar-pharyngeal area while vigorously swabbing the tonsils or tonsillar crypts and the posterior pharyngeal wall (2, 4, 8–10). If the swabs have to be transported to a laboratory, care should be taken to avoid conditions that are suboptimal for the survival of streptococci, such as high temperatures and swabs that remain moist for long periods (10). On the growth media in commercial swabs, 50 however, beta–haemolytic streptococci can remain viable for up to 48 hours (9). In some countries a number of kits are commercially available for rapidly detecting group A streptococci on throat swabs, either in a “near-patient” situation or in a laboratory. Most of these tests use an immunological method to detect a carbohydrate cell-wall antigen specific to group A streptococci in material from throat swabs, and do not require expert laboratory skills. Detecting the antigen is the most specific method for confirming the presence of group A streptococci and the kits have reported specificities in the range 85–100%, com pared with blood agar cultures (8, 11). False-positive results are unusual and therapeutic decisions can be made with confidence. In such circumstances, it is recom mended that negative kit results should be confirmed by culturing (2, 8). Neither culturing nor rapid testing can reliably distinguish be tween an acute streptococcal infection, and a streptococcal carrier (12) with a concomitant viral infection (13). Serological examination for streptococcal antibodies (antistreptolysin-O, antideoxyri bonuclease B) is not required for cases of uncomplicated streptococ cal upper respiratory tract infection, except in specific cases. The most commonly performed and commercially avail able tests are the antistreptolysin-O test, and the antideoxyri bonclease B test (12, 14). Kits for the antihyaluronidase test are no longer marketed, and an alternative test that uses the simultaneous detection of several antibodies has been reported to be unreliable (15). The blood titres of antistreptolysin-O, antideoxyribonuclease B and other antibodies raised against extracellular antigens of streptococci reach a peak 3–4 weeks after the acute infection, and usually are maintained for 2–3 months before declining (12). A serum antibody is judged to be elevated if the titre exceeds the upper limit of the normal titre range for a community, where upper limit is defined as the titre exceeded by no more than 20% of the population. The range of normal values for each test is variable and depends upon the age of the patient, geo graphical locale and the season of the year (see Table 6. The upper limit of normal can be determined by measuring antibody titres in a subset of sera from individuals without a recent streptococ cal infection and who belong to the appropriate age group. An anti body standard, or reference serum with a known titre, should be used as a control with each set of antibody determinations. This applies to taking throat swabs, trans porting swabs to the laboratory, culturing and identifying the microbes, as well as to the procedures used for the antibody test (1, 2, 8–10). It is relatively simple to maintain standards by continuing to train laboratory staff (3), and this is achievable by most countries. The microbiology laboratory also contributes to the study and control of actual outbreaks of group A beta-haemolytic streptococci, and allows any suspected outbreaks to be evaluated accurately. The following three levels of laboratory expertise are recommended, to meet most needs for diagnostic and reference streptococcal services. Peripheral laboratories handle immediate routine diagnostic tests, such as throat cultures, and also antibody tests. In certain cases, diagnostic testing may be referred to an intermediate laboratory or to a national streptococcal reference laboratory. They should be able to handle more specimens and carry out more sophisticated testing. All countries should be serviced, either nationally or internationally, by such laborato ries that can provide reference strains and expert advice on labora tory standards and training, as well as carry out typing (molecular and traditional) of the streptococcal strains.
