Complete drainage and debridement of all infected and necrotic soft tissue and bone is required discount cleocin gel 20 gm mastercard. Debridement decreases the bacterial load and allows for a more thorough examination of the area order 20gm cleocin gel overnight delivery. Any foreign bodies found at this time should be removed if possible cheap cleocin gel 20gm amex, and blood supply should be restored. Patients with orthopedic implant-related osteomyelitis should be managed individually, weighing the risk of recurrence against the functional outcome if the implant were removed. Failure to remove orthopedic implants sometimes allows microorganisms to form a biofilm and to escape antibiotics. Ideally, all orthopedic hardware should be removed at the time of bone debridement to allow for cure of infection. However, this is not possible in patients whose fractures have not developed union, because an infected union fracture is easier to deal with than an infected nonunion. In these cases, prolonged antibiotics while the fracture heals may be necessary, followed by removal of the hardware at a later date, in an attempt to fully cure the infection. In some patients with acute implant-related osteomyelitis, with < 1-month duration of symptoms, debridement and retention of hardware, followed by 3 to 6 months of a com- 13 Osteomyelitis 219 bined quinolone and rifampin regimen may provide a cure. Additionally, if a foreign body is not able to be removed, and the pathogen is identified to be S. Medical Therapy Medical management is predominantly directed toward any metastatic foci of infection and at microfoci of osteomyelitis that remain after surgical debride- ment. Braun The Infectious Diseases Society of America recommends that parenteral antibi- otics be started in a controlled setting, preferably inpatient, to carefully monitor for any serious side effects. Antimicrobial drug levels should be monitored, when indicated, to maximize efficacy and minimize toxicity. In acute hematog- enous osteomyelitis, antibiotics may be the only intervention required. In the many cases, after 7 to 10 days of intravenous antibiotic therapy, the patient may be changed to an oral agent for 3 to 4 additional weeks. In adults with uncom- plicated vertebral osteomyelitis, at least 4 to 6 weeks of antimicrobial therapy are necessary. In patients with chronic or contiguous focus osteomyelitis, anti- biotic therapy should be continued for at least 4 to 6 weeks. In patients with implant-associated osteomyelitis, the duration of antibiotic therapy should be adjusted according to the surgical modality. Typically, all infected hardware is removed, and the involved bone is debrided, followed by 4 to 6 weeks of effective antimicrobial therapy. This antibiotic regimen will allow time for the debrided bone to be covered by vascularized soft tissue. Hyperbaric Oxygen Therapy Although antimicrobial therapy and surgery are the cornerstones of treatment, adjunct modalities are available. Hyperbaric oxygen can be used in combination with antibiotics and surgery when treating patients with recurrent posttraumatic or chronic osteomyelitis. The hyperbaric oxygen increases the oxygen tension in infected tissue, including bone. This has a direct bacteriostatic as well as a bacteri- cidal effect on anaerobic organisms. In a randomized trial, patients with significant infected lower extremity ulcers treated with hyperbaric oxygen had a significantly lower amputation rate. Follow-Up After patients are discharged from the hospital, it is important for care to be continued as an outpatient. Many of these patients will receive antibiotic therapy intravenously for several weeks after discharge. The physical exam should include temperature, examination of the site, and inspection of any intravenous access. Early postoperative wound healing problems and infection have been associated with subsequent deep, surgical site infections. Therapeutic drug lev- els and toxicity can be measured weekly through serum assays. Subtherapeutic antimicrobial blood levels may be associated with levels that are below the minimal inhibitory concentra- tion of selected organisms, and can lead to clinical failure or the emergence of resist- ance. Radiological reevaluation may be done at any time if there are signs of treat- ment failure. In a patient who is progressing well, plain radiographs should be rechecked after 8 to 12 weeks from therapy initiation to assess for bony fusion in infected nonunion sites. Chronic osteomyelitis is more likely to develop in the contiguous focus patient, especially if there is a foreign body present. Even with appropriate medical and surgical treatment, and meticulous follow up, relapse is common. Chronic osteomyelitis imparts a massive economic burden and has a significant impact on quality of life. Amputation may be necessary, especially in diabetic patients and patients with peripheral vascular disease. In all cases, patient compliance is one of the most important prognostic indi- cators. Each patient should know about the natural history and management of osteomyelitis. They should be clearly informed about the pathophysiology, symptoms, therapy, and prognosis. Delay elective orthopedic surgical proce- dures if the patient has a current or recent history of infection. During orthopedic surgery, careful attention is paid to sterile techniques and to practices that reduce 222 K. Prophylactic antibiotic therapy can be administered at the time of surgery and for 24 hours postoperatively to achieve adequate tissue levels. The incidence of hematogenous distribution of infection can be decreased if urinary catheters and drains are removed as soon as possible. Proper wound care reduces the occurrence of superficial infections and osteomyelitis. Prompt management of soft tissue infections reduces expansion of infection to the bone. In patients with open contaminated fractures involving extensive injury or loss of soft tissue, periosteal stripping, and bone exposure, administer antimicrobial prophylaxis and perform surgical debridement and delayed wound closure. In one study involving 1,102 open fractures, the infection rate was 24% in patients receiving no prophylactic antibiotics, whereas the infection rate was 4. Patients with diabetes or peripheral vascular disease should be instructed on proper foot care. Patients should perform daily foot inspection, have an annual foot exam by a physician, and accommodate any foot deformities with custom-made footwear. They should use gentle soap and water to cleanse their feet and apply moisturizer afterwards. Two studies that used a multiple intervention program, including footwear, showed reduced rates of repeat ulceration in patients with a history of ulceration.
Assuming that a patients weight remains stable cheap 20gm cleocin gel visa, with no alterations to their medication or change in co-morbidities order 20 gm cleocin gel otc, the dose of levothyroxine should in theory remain stable generic cleocin gel 20 gm with amex. There are several factors that require alterations in doses such as pregnancy, malabsorption and medication. Any state that produces intestinal malabsorption, such as coeliac disease, may lead to reduced uptake of thyroxine and hence a need to increase thyroxine dose. It is important to be weary of individuals who suddenly need an increase in thyroxine and who complain of gastrointestinal symptoms. Patients prescribed these medications should be advised to take them at least 2-4 hours apart from their thyroxine. Provided malabsorption is ruled out, a large dose of supervised levothyroxine replacement (1 mg/week) can be attempted, which fixes the problem in the majority (Grebe et al 1997). Main symptoms and signs in autoimmune hypothyroidism 184 Thyroid and Parathyroid Diseases New Insights into Some Old and Some New Issues 3. Prompt treatment with intravenous levothyroxine is required, initially with a loading dose, followed by smaller maintenance doses which can be given orally if the patient is able. No consensus exists as to whether T3 treatment should commence at the same time, or indeed if T3 alone is all that is required (Kwaku & Burman 2007). Caution is needed in the elderly, or those with cardiovascular disease due to increased risk of myocardial infarction and tachyarrhythmia. Concurrent use of intravenous glucocorticoids are usually required during initiation of thyroxine treatment due to the potential for evoking an adrenal crisis in the first few days as the hypothalamic-pituitary-adrenal axis is usually impaired in severe hypothyroidism. Other supportive measures include blankets to warm the patients slowly, cautious use of intravenous fluid to treat hypotension and a low threshold for broad spectrum antibiotics if infection is thought to be implicated. Consideration should be given early to intubation and mechanical ventilation if deemed appropriate, especially in a comatose patient. It is particularly important during the first trimester, before the foetal thyroid is formed, that normal maternal levels of T4 are maintained as they play a vital role in foetal neurological development (Williams 2008). Conclusion Thyroid dysfunction can represent a wide spectrum of disease and the consequences of under treatment are evident with the two extremes of thyroid storm and myxoedema coma. Ongoing research into such areas is likely to provide further insight into the conditions and new therapies. Even with an expansion of the evidence base, clinical experience is likely to remain an invaluable asset in many instances.

Introduction One of the earliest references to a successful surgical attempt for the treatment of goitre can be found in the medical writings of the Moorish physician Ali Ibn Abbas. The first accounts of thyroid surgery for the treatment of goiters were given by Roger Frugardi in 1170. In response to failure of medical treatment, two setons were inserted at right angles into the goiter and tightened twice daily until the goiter separated. The first successful typical partial thyroidectomy was performed by the French Surgeon, Pierre Joseph Desault, in 1791 during the French Revolution. Dupuytren followed in 1808 with the first total thyroidectomy, but the patient died 36 hours after the operation. Despite these limited descriptions of early successes, the surgical approach to goitre remained shrouded in misunderstanding and superstition. Thyroid surgery in the 19th century carried a mortality of around 40% even in the most skilled surgical hands, mainly due to haemorrhage and infection. The French Academy of Medicine actually banned thyroid surgery in 1850 and German authorities called for restrictions on such foolhardy performances. Leading surgeons avoided thyroid surgery if at all possible, and would only intervene in cases of respiratory obstruction. Samuel Gross wrote in 1848: "Can the thyroid gland when in the state of enlargement be removed? It was not until the late 1800s after the advent of ether as anesthesia, antiseptic technique, and effective artery forceps that allowed Theodor Kocher to perfect the technique for thyroidectomy. Kocher used the technique of precise ligation of the arterial blood supply to perform an unhurried, meticulous dissection of the thyroid gland, decreasing the morbidity and mortality associated with thyroid surgery to less than 1% ( Giddings,1998). Advancements could only take place in the field of thyroid surgery with the introduction of improved anaesthesia, antiseptic techniques, and improved ways of controlling 190 Thyroid and Parathyroid Diseases New Insights into Some Old and Some New Issues haemorrhage during surgery. The first thyroidectomy under ether anaesthesia took place in St Petersburg in 1849; the second half of the 19th century saw the introduction of Listers antiseptic techniques through Europe, and the development of haemostatic forceps by such figures as Spencer Wells in London led to much better haemostasis than could be achieved by crude ligatures and cautery. Theodor Billroth (18291894), who performed thousands of operations with increasingly successful results. However, as more patients survived thyroid operations, new problems and issues became apparent. In 1909, Kocher was awarded the Nobel Prize for medicine in recognition "for his works on the physiology, pathology, and surgery of the thyroid gland. By the end of the twentieth century, laparoscopy was already accepted worldwide for a large number of operations in general surgery. By minimizing the size of the skin incisions while still permitting superior visualization of the operative field, laparoscopy was proven for certain operations to lessen postoperative pain, improve cosmesis, and shorten postoperative hospital stays. As minimally invasive surgery became more popular,surgeons realized some true limitations. Sensory information is limited due to lack of tactile feedback and restriction to a two-dimensional (2D) image. In addition, compared to the human hand in an open case,laparoscopic instruments have restricted degrees of freedom mainly due to the lack of a wrist-like joint in the instrument tip and the lack of maneuverability due to a fixed axis point at the trocar ( Hansen et al.
Everyone should know their blood pressure numbers order cleocin gel 20 gm on line, even when they are feeling fne buy cleocin gel 20 gm line. If their blood pressure is normal cleocin gel 20gm on-line, they can work with their health care team to keep it that way. If their blood pressure is too high, there are ways to lower it to prevent more damage to their bodies or at least to reduce that damage. As a valuable member of your community and of the health care team, you have a central role in teaching people about high blood pressure, in helping them to prevent high blood pressure, and to control it if they already have this problem. Sometimes, high blood pressure is caused by other medical problems, such as kidney disease. A risk factor is a condition or habit that makes a person more likely to have a disease or condition. Talking Points: When you meet with community members, make sure to talk with them about risk factors. Some risk factors for high blood pressure cannot be changed, such as older age and family history. The good news is that people can prevent or lower their risk for heart disease and stroke by choosing healthy lifestyle habits, or healthy ways to live. It is always good to encourage people of all ages to lead healthy lifestyles to reduce their risk of heart disease and other illnesses. Examples of good habits include the following Eat a healthy diet that is low in sodium and includes fruits and vegetables, whole- grain bread and pasta, low-fat dairy and lean meats, chicken and fsh. If your blood pressure is still not under control or if you have any problems with the medicine, talk with your doctor, nurse, or pharmacist about possibly changing your medicine. Sodium is part of salt and is used to add favor to food, but most Americans take in more sodium than their bodies need. Too much sodium can make your body hold on to fuids, and that can increase blood pressure. Daily intake of sodium for people without high blood pressure should not be more than 2,300 milligrams (mg), or about 1 teaspoon (use a teaspoon from a set of measuring spoons). Because foods that are not made at home can contain so much sodium, members of the health care team need to help patients learn how to read the nutrition labels on foods and meals they buy in a store. In addition, they need to help patients learn how to follow a low- sodium eating plan that works. People who are overweight or obese are more likely to have high blood pressure than are those who have a normal weight. The more you weigh, the more blood your body needs, and this leads to more pressure on the walls of your arteries. Being active will help you get to a healthy weight, look and feel better, get around more easily, and can even help you prevent diabetes and other diseases. Being active at a moderate level means that you can talk to others easily during the activity. If you become too out of breath to talk to others, your level of activity is vigorous, not moderate. Even if you are active in other ways, sitting for a long time puts you at risk for high blood pressure. If you are sitting for an hour or more, walk around for at least 5 minutes every hour. Drinking alcohol damages the artery walls, and so if you drink alcohol, you must drink wisely. For men, that means two drinks a day at most, and for women, one drink a day at most. African Americans develop high blood pressure more often than whites, and African Americans tend to get this problem at an earlier age and at a more serious level. People who have these diseases are more likely to have high blood pressure than those who dont have these problems. This means people who have diabetes or uncontrolled high blood pressure should have a test for kidney function every year. Usually, the older you get, the greater your chance of developing high blood pressure. Men seem to develop high blood pressure most often between age 35 and 55, but after age 65, high blood pressure is much more common in women than in men. If your parents or other close relatives have high blood pressure, heart disease, or diabetes, you are more likely to develop it yourself. Beyond family history, if you have poor lifestyle habits you are more likely to develop high blood pressure. If you stop taking your medicines, your blood pressure will no longer be under control, and you put yourself in danger. Changing your unhealthy habits is key for people who have the risk factors for high blood pressure, for high blood cholesterol, or for diabetes. It is important for these people to take their doctors advise and take medicines that the doctor may prescribe for them. Healthy HabitsTake Steps to Prevent and Control High Blood Pressure Activity 7-3. Talking Points: A persons blood pressure is written in two numbers, with a line between the two. The diastolic (bottom) number is the pressure when your heart is flling with blood or resting between beats. For adults, a systolic blood pressure of less than 120 or a diastolic pressure of less than 80 is best. If your adult patients have blood pressure numbers in this range, tell them to keep up the good work. If a person has a systolic pressure of 120139, or a diastolic pressure of 8089, make sure to talk with them about making healthy food and lifestyle choices that might help them lower their blood pressure. Other Questions to Ask Your Doctor Review the handout titled What Do Blood Pressure Numbers Mean? Give them sets of systolic and diastolic numbers and have them explain to a partner in the class what the blood pressure numbers mean. Talking Points: If a person has a systolic pressure of 140 or higher or a diastolic pressure of 90 or higher, make sure to talk with him or her about how important it is to make an appointment with their health care provider for follow-up. Also, encourage them to make healthy food and lifestyle choices to help them lower their blood pressure. Sometimes a person can have a blood pressure so high that they need to get help right away. If you measure someones blood pressure and fnd that the systolic number is 160 or greater or the diastolic number is 100 or greater, advise that person to call his/her health care provider immediately. If they do not have a doctor, nurse, or clinic they can call, use your community resources to help them fnd a medical provider who can help them. People who have diabetes should talk to their doctor about the goals for their blood pressure numbers. Important Message: After you have taken a persons blood pressure and found it to be high, please do not tell that person that he or she has high blood pressure.

The infammatory and fbrotic process destroys the normal architecture of the af- fected organs leading to dysfunction and failure. The result- ing fbrosis leading to atrophy and failure of the afected organs largely determines the out- come of the disease process. However, despite intense research eforts the relationship and interaction between the pathophysiological processes afecting the vascular system, the immune system and the extracellular matrix are only incompletely understood. The mechanisms inducing the antibody production are unknown but clinical associations with autoantibody specifci- ties suggest that these antigen-restricted responses are involved in disease specifc pathol- ogy. Tese antibodies bind to the receptors, stimulate re- spective signalling pathways and lead to increased type I collagen gene expression in fbro- blasts (Baroni et al. Antibodies directed to cell surface molecules inducing thereby 174 Nicolas Hunzelmann and Thomas Krieg signal transduction pathways are an intriguing concept, which is currently discussed in the pathophysiology of several unrelated diseases e. Tese autoimmune phenomena are in a not well under- stood way related to the infammatory process with lymphocytic perivascular infltrates in the skin and lung evident early on in the disease process and preceding the development of fbrosis (Gabrielli et al. The similarity of the condition with some aspects of graf versus host disease has frequently been noted. However, subsequent studies found similar frequencies of microchimerisms compared to normal controls but nevertheless an increased number of microchimeric fetal cells in patients (Burastero et al. Vascular Pathology The relationship between autoimmune responses and the vascular pathology is unclear, as Raynauds syndrome and vascular abnormalities may be evident many years prior to the onset of disease (Blockmans et al. The combination of a fbrotic microvascular and hy- perreactive vasoconstrictor status is thought to represent the primary lesion responsible for the vasospastic episodes. Tissue hypoxia normally induces new blood vessel growth by induction of a variety of angiogenic factors. Recently, hypoxia has been linked to the in- duction of epithelial-mesenchymal transition, an evolving concept for the pathogenesis of fbrosis of the lung. Dysregulation of Extracellular Matrix Synthesis The dysregulation of extracellular matrix synthesis is the third major pathophysiologic change, with the extent and progression of the fbrotic process being important prognos- 4 Scleroderma 175 tic factors in the disease process. It has been well established by in situ hybridization and by fbroblast cultures obtained from involved tissue (e. The newly synthesized extracellular matrix is deposited particularly around skin appendages and at the border of the dermis to the subcutaneous tissue, partially replacing the latter (Perlish et al. The collagen bundles running parallel with the skin surface show swelling and variation in thickness. Although the biosynthesis of collagens has been investigated in detail, its metabolism and turnover in vivo is not yet fully understood. Similarly, in a fbrotic dis- ease, the net gain of collagens must thus involve a disturbed balance between the synthetic and degradative processes. The most commonly used approach to study collagen degra- dation is the study of collagen degrading enzymes (Herrmann et al. However, the results are difcult to interprete in terms of the in vivo situation, as a combination of several enzymes including the corresponding inhibitors are likely to be in- volved in the degradation of a single collagen fber. A diferent approach to this question is to study the degradation products as they appear in vivo. Furthermore these crosslinks can usually only be detected in bone, suggesting that occurence of these crosslinks in the skin is related to the sclerotic process. The deposi- tion of molecules which are not organotypic may contribute to the resistance to remodel- ling which is a characteristic feature of fbrosis. The factors which fnally lead to the activated phenotype of scleroderma fbroblasts are not entirely clear. The disease is much commoner in females than males for rea- sons that are not entirely clear with a female-to-male ratio of 39:1. Both forms, however, lead to life threatening involvement of internal organs and are associated with marked excess mortality. The quality of life is severely re- duced and the patients require continous medical support. The two major clinical variants are distinguished primarily on the degree and extent of skin involvement. For instance, a signifcant number of patients belongs to a subgroup with symptoms of sys- temic sclerosis occuring simultaneously with those of other connective tissue diseases like myositis, Sjgrens syndrome or lupus erythematodes.
