See also the special issue of the Interna tional Journal of Osteoarchaeology (1996, 6 (1)) which contains several papers on battle and other trauma. The kinetic energy in turn, depends upon the weight and velocity of the projectile, the latter of which would have been relatively low under recent times. Entry wounds are usually round or oval and have a sharp punched-out appearance on the external table with a bevelling on the internal table. The exit wound is larger than the entry wound and shows bevelling on the external surface. Where there is more than one gunshot wound to the head, the pattern of fractures can sometimes be used to determine the sequence44 and direction45 of re. Gunshot wounds can sometimes be confused with other types of damage, and where there is doubt about the origin of the wound it is useful to X-ray the skull since in the case of a gunshot wound, there will be radiodense particles of lead around the entry and the exit wounds. Gunshot wounds to long bones are usually comminuted, the fragments sometimes taking a ‘butter y’ appearance, but a single drill hole appearance is also sometimes seen. There is generally less damage in cancellous than in cortical bone because the kinetic energy of the projectile is dissipated more readily in areas of trabecular bone. In the absence of anaesthesia and adequate analgesia, the operation was over in very short order and the chances of survival were extremely poor. Robert Liston (1794–1847), who was a surgeon at University College Hospital in London was one of the most skilled of the early nineteenth-century surgeons. As performed in the sixteenth and seventeenth centuries, the soft tissues were cut with a single circular cut down to the bone, which was then sawn through. Later soft-tissue aps were devised to close the wound, and two or three cuts would be made to sever the soft tissue. Not until Lister introduced his carbolic spray did the case fatality rate approach acceptable limits (15%inhisown case). Some shrewd observer might surely have noticed that those whose wounds were not infected were more likely to survive that those with stinking, infected stumps. The breakaway point has only a single surface (arrowed) showing that the surgeon made only one cut with the saw to detach the leg. Bones from amputees are most likely to be found in assemblages from hospital sites, and they may be the distal bones, that is, the part of the limb that was dis carded, or the remnant of the proximal stump that was still attached to the patient (Figure 8. The amputated limbs are easily recognisable by the kerf made by the surgeon’s saw,53 and there is almost always a breakaway point on the distal bone which is made as the bone parts. This breakaway point will have as many sides as therewerecutswiththesaw,eitheroneortwo. Thedistalbonewill–ofcourse–show no evidence of healing, but on some rare occasions, the proximal end may do so, indicating that the patient was lucky enough to survive at least for some months after the operation, sometimes considerably longer. This might have included a compound fracture, osteomyelitis, a tumour of either bone or soft tissue or an aneurysm of a peripheral artery. In the middle of the nineteenth century, the most common 53 the kerf mark is the groove made by a cutting tool; in the case of a saw, the kerf is wider than the saw blade and the physical characteristics of the kerf may often allow the type of saw used to be identi ed; this is particularly useful in forensic medicine. The case fatality rate was very high and almost half the patients died following the operation. The most common method involved scraping away the bone using a stone or metal implement, cutting out a square or rectangle of bone with four separate cuts; or drilling and removing a circle or ellipse of bone. Trephination sensu strictu refers to the removal of a circular piece of bone using an instrument with a circular, saw-toothed blade, known as a trephine. Trepanation, on the other hand, has its roots in the Greek word, trepa ( O ), meaning a hole. One patient described by Margetts had no fewer than ve operations, initially for a headache following a blow to the head, and virtually the whole of his calvarium had been removed. There are also those who drill holes in their skulls using an electric drill, usually in total ignorance of the anatomy of structures within their head; one such individual succeeded in drilling into the sagittal sinus producing a spectacular haemorrhage. Some skulls have several holes in them and it may be that these are skulls on which trainees practiced prior to taking up their art on the living. Holes made with cutting tools or drills are easy to recognise but those made by scraping may sometimes be confused with other pathological lesions and there may be some dif culty in arriving at a de nitive diagnosis. They will also lack any fracture lines that might be associated with impact trauma. They may show signs of in ammation or infection, and they may also show signs of healing and remodelling although, of course, the hole is never lled. The Greek and Roman anatomists generally contented themselves with studies on animals. Galen, the most in uential of the ancient physicians save Hippocrates, apparently had only two human skeletons to study, and by extrapolating his ndings on animals to humans, made a number of errors that were perpetuated until the times of Vesalius. St Augustine was strongly opposed to dissection, for humanitarian and aesthetic, rather than religious reasons, but the decree promulgated at the Council of Tours in 1163 that ecclesia abhorret a sanguina was widely interpreted to mean that the clergy should not perform surgery on either the living or the dead. Although the ban was speci c in its instructions, many considered that any dissection was thereby prohibited. Mondino de Luzzi’s in uential Anathomia, based at least in part on human dissection, appeared in the fteenth century and was frequently reprinted during this and the following century. The greatest single advance in the study of anatomy, however, came with the publication of the great work by Andreas Vesalius, De corporis humani fabrici, published in 1543 with wonderful woodcuts, some of which were made by Stephan van Calcar, who had been a pupil of Titian. This book, which nally overthrew the Galenical system of anatomy was based on dissection and is one of the most in uential of medical books ever published. This was a largely uncritical work, however, and the new era of empirical medicine, that is, one that was based on observation rather than deduction was exempli ed by the publication of Giovanni Morgagni’s De sedibus et causis mor borum, published in Morgagni’s eightieth year, in 1762. Thisbookcanbesaidto have ushered in the great period of pathological anatomy, exempli ed in England by the work of John Hunter and his various pupils in the eighteenth century, by Bichat, Corvisart, Laennec and Louis in Paris in the early nineteenth in the after math of the Revolution, and by Skoda and Rokitanski in Vienna during the later nineteenth. In a partial autopsy the viscera in the abdomen and/or chest are examined, but the skull is not opened, whereas it is when the autopsy is complete. Where the autopsy was con ned to an examination of the abdomen, there may be no signs on the skeleton. On the other hand, when the heart and lungs were examined, it would have been necessary to cut through the rib cage and this should be evident on the skeleton. The anatomy of pathology in the early nineteenth century, Cambridge, Cambridge University Press, 1987. Skeleton from late eighteenth or early nineteenth century context with the calvariumremoved,theclassicsignofanautopsy. Autopsy material becomes relatively more common after the eighteenth century and a study of the cuts on the skull may often give some indication of the skill of the operator. Skulls may be found showing tentative saw cuts and – usually – several de nite cuts; sometimes it can be seen that the calvarium was levered off, leaving an irregular, fractured edge. In some cases, the laminae of the vertebrae are sawn through to remove the spinal cord, presumably with the brain, so that the central nervous system could have been studied. As with amputations, there is usually nothing on the skeleton to indicate why the autopsy was undertaken, whether it was for forensic, pathological or anatomical purposes. For example, bones with evidence of autopsy cuts were recovered from Benjamin Franklin’s house in London, which had been the site of William Hewson’s anatomy school from 1772–1774, and were clearly part of material that had either been used for demonstrations to Hewson’s pupils, or preparations they had made themselves (S Hillson, T Waldron, B Owen-Smith and L Martin, Benjamin Franklin, William Hewson and the Craven Street bones, Archaeology International, 1998–1999, 2, 14–16). In the United Kingdom, common criminals were put to death by hanging but the nobility generally preferred to have their lives ended by decapitation with the sword or the axe for reasons that defy a ready explanation. Beheading Beheading results in characteristic damage to the skeleton and there is usually no dif culty in deciding when it has taken place. Finding a skeleton with its head between its legs ought generally to alert the excavator to the possibility and the suspicion will be con rmed by nding that one or the other of the cervical vertebrae has been transacted. There is sometimes a cut mark on the back of the mandible, the mastoid process or the rst rib. When an axe rather than a sword has been used by the executioner, crush fractures of the transverse processes may also be found. Until the nineteenth century, hanging was performed with a running noose and the victim suspended from a gallows or some other convenient structure such as the branch of a tree. The victim was either hoisted up by the rope which was tied, leaving him in place, or he might be placed on a cart with the noose around his neck and the cart withdrawn, leaving him dangling until he strangled to death. During the later medieval period and into the eighteenth century, the victim climbed a ladder with a noose around his neck, the executioner 68 S Ulrich-Bochsler, Skettale Befunde bei historischen Enthauptungen im Kanton Bern, Archiv f ur Kirmi nologie, 1988, 181, 76–83.

Buffered and enteric coated preparations are only marginally helpful in dealing with this problem antibiotic injection rocephin buy 500mg tetracycline free shipping. Low doses (60a“81 mg daily) of aspirin can irreversibly inhibit thromboxane production in platelets via acetylation of cyclooxygenase horse antibiotics for dogs order tetracycline 250 mg without a prescription. Because platelets lack nuclei antibiotics for sinus infection if allergic to amoxicillin buy discount tetracycline 250 mg, they cannot synthesize new enzyme virus free music downloads 500mg tetracycline with mastercard, and the lack of thromboxane persists for the lifetime of the platelet (3a“7 days). Decreased synthesis of prostaglandins can result in retention of sodium and water and may cause edema and hyperkalemia in some patients. Commonly treated conditions requiring analgesia include headache, arthralgia, and myalgia. External applications: Salicylic acid is used topically to treat corns, calluses, and warts. Methyl salicylate (a oil of wintergreena) is used externally as a cutaneous counterirritant in liniments. Administration and distribution: After oral administration, the un-ionized salicylates are passively absorbed from the stomach and the small intestine (dissolution of the tablets is favored at the higher pH of the gut). Rectal absorption of the salicylates is slow and unreliable, but it is a useful route for administration to vomiting children. Salicylates (except for diflunisal) cross both the blood-brain barrier and the placenta and are absorbed through intact skin (especially methyl salicylate). Dosage: the salicylates exhibit analgesic activity at low doses; only at higher doses do these drugs show anti-inflammatory activity (Figure 41. Fate: At dosages of 650 mg/day, aspirin is hydrolyzed to salicylate and acetic acid by esterases in tissues and blood (see Figure 41. Salicylate is converted by the liver to water-soluble conjugates that are rapidly cleared by the kidney, resulting in elimination with first-order kinetics and a serum half-life of 3. At anti-inflammatory dosages (>4 g/day), the hepatic metabolic pathway becomes saturated, and zero-order kinetics are observed, with the drug having a half-life of 15 hours or more (Figure 41. Being an organic acid, salicylate is secreted into the urine and can affect uric acid excretiona”namely, at low doses of aspirin, uric acid secretion is decreased, whereas at high doses, uric acid secretion is increased. Both hepatic and renal function should be monitored periodically in those receiving long-term, high-dose aspirin therapy, and aspirin should be avoided in patients with a creatinine clearance of less than 10 mL/min. At stomach pH, aspirin is uncharged; consequently, it readily crosses into mucosal cells, where it ionizes (becomes negatively charged) and becomes trapped, thus potentially causing direct damage to the cells. Aspirin should be taken with food and large volumes of fluids to diminish dyspepsia. For this reason, aspirin should not be taken for at least 1 week prior to surgery. When salicylates are administered, anticoagulants may have to be given in reduced dosage, and careful monitoring and counseling of patients are necessary. Respiration: In toxic doses, salicylates cause respiratory depression and a combination of uncompensated respiratory and metabolic acidosis. Metabolic processes: Large doses of salicylates uncouple oxidative phosphorylation. The energy normally used for the production of adenosine triphosphate is dissipated as heat, which explains the hyperthermia caused by salicylates when taken in toxic quantities. Hypersensitivity: Approximately 15 percent of patients taking aspirin experience hypersensitivity reactions. This is especially encountered in children, who therefore should be given acetaminophen instead of aspirin when such medication is required to reduce fever. Drug interactions: Concomitant administration of salicylates with many classes of drugs may produce undesirable side effects. Because aspirin is found in many over-the-counter agents, patients should be counseled to read labels to verify aspirin content to avoid overdose. Salicylate is 90 to 95 percent protein bound and can be displaced from its protein-binding sites, resulting in increased concentration of free salicylate; alternatively, aspirin could displace other highly protein-bound drugs, such as warfarin, phenytoin, or valproic acid, resulting in higher free concentrations of the other agent (Figure 41. Chronic aspirin use should be avoided in patients receiving probenecid or sulfinpyrazone, because these agents cause increased renal excretion of uric acid whereas aspirin (<2 g/day) cause reduced clearance of uric acid. Because salicylates are excreted in breast milk, aspirin should be avoided during pregnancy and while breast-feeding. The mild form is called salicylism and is characterized by nausea, vomiting, marked hyperventilation, headache, mental confusion, dizziness, and tinnitus (ringing or roaring in the ears). When large doses of salicylate are administered, severe salicylate intoxication may result (see Figure 41. The symptoms listed above are followed by restlessness, delirium, hallucinations, convulsions, coma, respiratory and metabolic acidosis, and death from respiratory failure. Ingestion of as little as 10 g of aspirin (or 5 ml of methyl salicylate, with the latter being used as a counterirritant in liniments) can cause death in children. Treatment of salicylism should include measurement of serum salicylate concentrations and of pH to determine the best form of therapy. In serious cases, mandatory measures include the intravenous administration of fluid, dialysis (hemodialysis or peritoneal dialysis), and the frequent assessment and correction of acid-base and electrolyte balances. All these drugs possess anti-inflammatory, analgesic, and antipyretic activity; additionally, they can can alter platelet function and prolong bleeding time. These drugs are reversible inhibitors of the cyclooxygenases and, thus, like aspirin, inhibit the synthesis of prostaglandins but not of leukotrienes. All are well absorbed on oral administration and are almost totally bound to serum albumin. Despite its potency as an anti-inflammatory agent, the toxicity of indomethacin limits its use to the treatment of acute gouty arthritis, ankylosing spondylitis, and osteoarthritis of the hip. They have long half-lives, which permit once-daily administration, and the parent drug as well as its metabolites are renally excreted in the urine. Meloxicam excretion is predominantly in the form of metabolites and occurs equally in the urine and feces. Their side effects, such as diarrhea, can be severe, and they are associated with inflammation of the bowel. Diclofenac accumulates in synovial fluid, and the primary route of excretion for the drug and its metabolites is the kidney. Tolmetin is an effective anti-inflammatory, antipyretic, and analgesic agent with a half-life of 5 hours. It is 99 percent bound to plasma proteins, and metabolites can be found in the urine. It is available for oral administration, for intramuscular use in the treatment of postoperative pain, and for topical use for allergic conjunctivitis. Ketorolac undergoes hepatic metabolism, and the drug and its metabolites are eliminated via the urine. This agent is to be avoided in pediatric patients; patients with mild pain, and those with chronic conditions, the dose should not exceed 40 mg/day. Nabumetone is hepatically metabolized by the liver to the active metabolite, which displays the anti-inflammatory, antipyretic, and analgesic activity. The active metabolite is then hepatically metabolized to inactive metabolites with subsequent renal elimination. Therefore, cautious use of this agent in patients with hepatic impairment is warranted; additionally, the dose should be adjusted in those with creatinine clearance of less than 50 mL/min. Unlike aspirin, celecoxib does not inhibit platelet aggregation and does not increase bleeding time. Pharmacokinetics: Celecoxib is readily absorbed, reaching a peak concentration in about 3 hours. Its half-life is about 11 hours; thus, the drug is usually taken once a day but can be administered as divided doses twice daily. The daily recommended dose should be reduced by 50 percent in those with moderate hepatic impairment, and celecoxib should be avoided in patients with severe hepatic and renal disease. Adverse effects: Headache, dyspepsia, diarrhea, and abdominal pain are the most common adverse effects. Celecoxib should be avoided in patients with chronic renal insufficiency, severe heart disease, volume depletion, and/or hepatic failure. Acetaminophen has less effect on cyclooxygenase in peripheral tissues, which accounts for its weak anti-inflammatory activity. Therapeutic uses Acetaminophen is a suitable substitute for the analgesic and antipyretic effects of aspirin for those patients with gastric complaints, those in whom prolongation of bleeding time would be a disadvantage, or those who do not require the anti-inflammatory action of aspirin. Acetaminophen does not antagonize the uricosuric agents probenecid or sulfinpyrazone and, therefore, may be used in patients with gout who are taking these drugs. A significant first-pass metabolism occurs in the luminal cells of the intestine and in the hepatocytes.

Tetanus is a condition characterised by prolonged, involuntary contraction of the skeletal muscles. Tetanus is caused by the bacterium Clostridium tetani, an obligate, anaerobic, Gram-posi tive rod-shaped bacterium. Tetanospasmin is a potent neurotoxin which blocks neuro transmitter release from inhibitory neurons resulting in muscular contractions. Initially, the upper part of the body is affected rst, most notably the facial muscles, resulting in ‘lockjaw’. Human tetanus immunoglobulin is a solution of human immunoglobulin G (IgG) containing a high level of anti-tetanus toxin antibodies. It is prepared from the plasma of screened, human donors immunised against tetanus toxin and is administered by intramuscular injection. The product also contains iso tonic sodium chloride, glycine, as a stabiliser, sodium acetate and a small amount of sodium hydroxide used to maintain pH. The anti-tetanus antibodies bind speci cally to tetanus toxin and neutralise the toxin by inhibiting its binding to neuromuscular receptors. This product is used in cases where there is a likely risk of tetanus infection or where clinical tetanus is observed. Human tetanus immunoglobulin should be administered as soon as possible after possible infection. Idiopathic thrombocytopenic purpura, also referred to as immune thrombo cytopenic purpura, is a bleeding disorder characterised by destruction of platelets. These antibodies label the platelets for destruction by macrophages in the spleen. Typically, the disease is transient with no evidence of vaccine-associated recurrence. Laboratory diagnosis is con rmed by persistent, low levels of platelets (throm bocytopenia), typically <150 109/L (normal reference range 150–450 109/L). A full blood count should be performed and this should not show any other abnormalities. Antiplatelet antibody tests may be performed but the latter may occur in other conditions so are not truly diagnostic. Thrombocytopenia with the associated signs, and the general feeling of well-being, are usually con rmatory. Typically these are accompanied by a feeling of illness, but must still be eliminated from the diagnosis. Corticosteroid treatment, oral prednisolone at 1 mg/kg body weight per day for 2–4 weeks, is the rst-line therapeutic approach. Where active treat ment is required, due to ongoing clinical episodes, such as prolonged bleeding, i. The antibody fraction is extensively purified and contains immunoglobulins in glycine. Where large volumes are required, the solu tion should be left to stand at room temperature prior to injection. This is rarely performed in children as the condition normally resolves spontaneously within six months. Where splenectomy is performed, the patient is more susceptible to infection but serious infections are rarely a problem in otherwise healthy individuals. Case study level 3 – Chronic granulomatous disease – see page 322 1 What is chronic granulomatous disease Clinical presentation is typically rst observed between the rst 2–5 years of life. The most common presentations include; skin infections, pneumonia, lung abscesses, enteritis and enlarged liver, spleen and lymph nodes. Granulomas are often formed in the skin, gastro intestinal and genitourinary tracts. Patients often present with infections caused by opportunistic, normally non pathogenic, microorganisms. The disorder is usually inherited as an X-linked disorder although an autosomal recessive inheritance may be the cause in one-third of cases. Genetic screening of family members helps to identify the likely type of inheritance. The defect is in a gene encoding the components of the phagocyte-oxidase system, namely cytochrome b588. As a result, the phagocytes are unable to produce superoxide anions that are central to the killing of microbial pathogens. In patients with active bacterial infections, initial Immunology case studies 331 parenteral administration of more aggressive antibiotic therapies are pursued. Interferon gamma is a potent activator of macrophages and is important for the killing of intracellular pathogens, most notably mycobacterial pathogens. The formulation used is a recombinant form of interferon gamma in a preparation containing D-mannitol, disodium succinate hexahydrate, polysorbate 20, suc cinic acid and water for injection. Monitoring typically involves observing the response of the infection by moni toring symptoms and by microbiological laboratory assessment. As with all cytokine-based therapies, the patient should be monitored for blood cell counts, kidney and liver status. The preparation should be stored in a refrigerator and checked for cloudiness prior to injection. The thighs or upper arms are the usual sites for injection and the site of injection should be varied to avoid tissue damage or irritation. The X-linked form is usu ally most severe and life expectancy may be 25–30 years. Case study level Ma – Chronic hepatitis B infection – see page 324 1a What is hepatitis B infection These are available as powders for reconsti tution or as pre lled injection pens. The drug is administered by subcutaneous injection (or intravenous for reconstituted powder formulations) and intra muscular injection. Powder formulations of interferon alfa-2b also contain glycine, sodium phosphate (mono and dibasic) and human albumin; pre lled pens contain sodium chloride, edetate disodium, polysorbate 80 and m-cresol as a preservative. Interferon alfa-2a formulations contain excipients sodium chloride, poly sorbate, ammonium acetate, and benzyl alcohol as a preservative. Interferon alfa is also approved for use in the treatment of several other disorders. Peginterferon formulations are also available (polyethyleneglycol conjugated interferon alfa). Lamivudine and adefovir dipivoxil belong to a class of antiviral compounds known as nucleoside analogues. In addition, white blood cell counts should be moni tored, as should cardiovascular function. The reported side-effects of interferon alfa include: cardiovascular problems such as arrhythmia, tachycardia and hypotension in the absence of history of such conditions, severe myelosuppression, depression and suicidal behaviour, opthalmic disorders, anorexia and ‘ u-like’ symptoms and hypersensitivity reactions. The patient should be informed that under no circumstances should he switch treat ments as different formulations may contain different dosages. Furthermore, he should be made aware of the proper disposal of used pens/syringes and to take extra care if blood enters the dispensers, as described in the product literature. Dietary advice may be offered as cytokine-based treatments often cause reduced appetite. Case study level Mb – Rheumatoid arthritis – see page 325 1 What is rheumatoid arthritis

Musculoskeletal and joint disease case studies 253 1d What parameters would you monitor as you consider this woman’s pharmaceutical care It is an in ammatory condition which follows a relapsing, remitting course, which can be very variable. The hands and wrists are most commonly affected although other joints may be involved. It is usual that the disease is found in symmetrical joints, although this is not always the case. The synovial lining of the joints becomes in amed and proteolytic enzymes are released which cause the bone and cartilage to be destroyed. Patients with rheumatoid arthritis may also suffer from wide range of symptoms which affect other parts of the body. These symptoms may include anaemia, dry eyes, osteoporosis and nodules, among other things. The cause of rheumatoid arthritis is unknown, but it is thought that a mixture of genetic and environmental factors affect whether someone develops the con dition. Some of the factors that have been linked to the development of rheumatoid arthritis include: I Previous family history – patients with a rst-degree relative with rheumatoid arthritis are more likely to have it themselves. I Gender – women are more likely to have rheumatoid arthritis than men I Previous infection – the onset of rheumatoid arthritis can occur after an infection. The Epstein–Barr virus, parvoviruses and mycobacteria have been linked to the development of rheumatoid arthritis. Patients will com plain of joint pain and a loss of function in the affected joints. The American Rheumatism Association developed a set of criteria by which to diagnose rheumatoid arthritis, although the criteria tend to apply to patients with established disease (Bryant and Alldred, 2007). The criteria state that the patient should have four or more of the following criteria to be diag nosed with rheumatoid arthritis: I morning stiffness lasting longer than 1 hour for a period of more than six weeks Musculoskeletal and joint disease case studies 255 I arthritis of at least three joints for more than six weeks I arthritis of hand joints lasting longer than six weeks I symmetrical arthritis of at least one area for longer than six weeks I rheumatoid nodules as observed by a physician I serum rheumatoid factor as assessed by a method positive in less than 5% of control subjects I radiographic changes as seen on anterioposterior lms of wrists and hands. A diagnosis of rheumatoid arthritis is made by assessing the presenting signs and symptoms. Biochemical investigations are performed and are useful in con rming the diagnosis. The patient will also be tested for the presence of rheumatoid factor and antinuclear antibodies. These tests are not speci c to rheumatoid arthritis but may help with diagnosis and manage ment of the condition. Sulfasalazine has an immuno modulatory effect as well as an antibacterial action. It also has in uences on the arachidonic cascade and alters the activity of enzymes involved in the in am matory process. Diarrhoea, nausea, vomiting, headache, rash, loss of appetite and raised temperature are the most common side-effects. Potentially fatal leucopenia, 256 Pharmacy Case Studies neutropenia, agranulocytosis, aplastic anaemia and thrombocytopenia may occur rarely. What is a sulfa drug and how does this affect the side-effect pro le of sulfasalazine Some patients can be allergic to this group of drugs which also includes sulfamethoxazole (found in Septrin) and some diuret ics, as well as other drugs. Allergic reactions to sulfa drugs can include rashes as well as more serious adverse drug reactions such as Stevens–Johnson syndrome and blood dyscrasias. Sulfasalazine is also licensed for treatment of mild to moderate and severe ulcer ative colitis and maintenance of remission, and active Crohn’s disease. Many patients with rheumatoid arthritis will have deformed joints, making it dif cult for them to open medicine bottles or to use blister packs. The patient should report any unexplained bleeding or bruising, purpura, sore throat, fever or malaise that occurs during the treat ment to her doctor as soon as possible. She should be advised that if she wears Musculoskeletal and joint disease case studies 257 contact lenses, her lenses may be stained. Further information on the speci c types of contact lenses affected can be obtained from the manufacturers. She should also be warned that this medication may cause her urine to be coloured orange. Diclofenac the patient should be told about the prescribed dose and when to take the tablets. The patient should be advised to take the medication with, or after food as diclofenac may cause stomach irritation. Case study level 2 – Rheumatoid arthritis – see page 246 1a How is the dose of sulfasalazine normally initiated and titrated The patient should start with one tablet daily, increasing their dosage by a tablet a day each week until one tablet four times a day, or two tablets three times a day are reached, according to tolerance and response. Nausea may be a problem for some patients, hence the dose is titrated up grad ually to avoid this. If she has an appointment in the very near future, her dose may be increased at that consultation. It is important to reiterate that the onset of action of the sulfasalazine is slow. Close monitoring of the full blood count and liver function tests is necessary initially and then at monthly intervals for at least the rst three months of treat ment. Renal function tests may be performed periodically as recommended by the manufacturers. Side-effects of sulfasalazine include blood dyscrasias which usually occur in the rst 3–6 months of treatment. The full blood count should be checked regularly so that any haematological abnormalities can be identi ed at an early stage. There have been reports of hepatitis and renal dysfunction in patients tak ing sulfasalazine, therefore liver function tests and renal function tests should be performed at regular intervals. As the symptoms initially appear to be related to her medication she may be experiencing gastric irritation as a result of her diclofenac or she may be suffer ing from nausea due to the sulfasalazine. With further questioning, it may be possible to clarify the symptoms and to ascertain whether one of the drugs is likely to be causing the problem.
