These techniques can be a less aggressive alternative to allergy medicine quiz buy zyrtec with amex surgery allergy testing online purchase generic zyrtec line, and may be indicated in cases of lung metastases associated with insufficient respiratory reserve allergy shots versus pills cheap zyrtec 5mg amex, poor patient clinical status, or after multiple previous surgical resections, local recurrence at the site of Thyroid Downloaded from online. In selected patients, they may be an alternative to surgery as first-line treatment, and they may induce local tumor control with a similar efficacy to surgical resection. Of interest, longterm benefits in terms of disease control have been reported in patients with a single or few metastases and in whom the disease is slowly progressive. The main principle of these techniques is to selectively treat the lesion, to be minimally invasive, to be well tolerated with relatively few side effects. The indications and the feasibility of each technique depend on the location and the size of the lesion to be treated. Experience with metastases from thyroid cancer is scarce, and most available data have been obtained in patients with metastases from non-thyroid cancers. It has been used in several trials to treat brain, liver, lung and bone metastases. It is usually well tolerated, and brain necrosis that occurred in less than 10% of cases is usually limited and had no clinical consequences. The patient outcome depends mostly on the progression rate of extra cerebral lesions (1015). Data on lung and liver metastases are available only in retrospective studies on low numbers of patients and with a median follow-up of less than 1 year in most cases and in one Thyroid Downloaded from online. This study included patients with many different primary tumors, including 10% of the patients having thyroid cancer. They showed a local control rate ranging from 63% to 98% in lung lesions, from 57% to 100% in liver lesions with a cumulative dose delivered ranging from 20-75 Gy in 5-15 fractions. The local tumor control seems to be long lasting with complete response ranging form 70 to 90 % at 2-3 years. Furthermore, rare (<3%) grade 3-4 toxicities (pneumonitis, pleural effusion, intestinal complications) were reported (1017). These toxicities are much less common that those associated with percutaneous treatment modalities. Concerning bone lesions, radiotherapy plays an important role because it can complement surgery in case of incomplete resection or be used alone for pain relief or palliation. Spinal myelopathy or vertebral fractures are the most important side effects, especially in case of large volume lesions. Percutaneous thermal ablation is aimed to destroy tumor foci by increasing (radiofrequency ablation) or decreasing (cryoablation) temperatures sufficiently to induce irreversible cellular damages. A multicenter prospective trial on 183 lung metastases from cancer other than colorectal showed a complete response rate of 88 % at 1 year and an overall survival of 92% and 64% at 1 year and at 2 years, respectively (1022). Cases of delayed recurrence have also been reported, and long-term follow up is needed. Furthermore, repeated treatments can be performed on the same lesion and multiple lesions can be treated in the same patient. The association of cryoablation and cementoplasty seems promising in purely lytic bone metastases from thyroid cancer. Published experience using thermal ablation and stereotactic radiation in thyroid cancer patients is limited, and recommendations are currently based on more robust evidence in other solid tumors. Randomized prospective studies comparing the efficacy and tolerability of these different techniques are lacking, and their choice in clinical practice is based on local experience, lesion location as well as patient status and preference. Surgical resection and stereotactic external beam radiotherapy are the mainstays of therapy (933;1029;1030). Stereotactic radiation therapy is preferred to whole brain irradiation because life expectancy in patients with brain metastases may be prolonged, and stereotactic irradiation induces less short and long-term toxic damages to the brain toxicity compared with whole brain irradiation (fatigue, headache, cognitive decline, and behavioral changes), and it may be effective even in patients with multiple brain lesions. Clinicians considering referral of patients for trials should review available treatment options and eligibility criteria, preferably through discussions with trial center personnel and review of trial materials at the website 246 Page 247 of 411 247 There is limited evidence that enrollment into clinical trials is associated with lower overall cancer-specific mortality for patients with common cancers, even within contexts in which approved and "standard of care" therapies already exist (1031).

Central to allergy symptoms from grass cheap 5mg zyrtec visa the question of why patients use e-health is the notion of medical expertise allergy forecast edinburgh purchase 5 mg zyrtec free shipping. At a broader level allergy shots 3 year old purchase zyrtec 10mg online, many scholars have commented on shifting views of authority in realms beyond medicine (Hartelius, 2008; Lankes, 2008; Mackiewicz, 2009). In participatory medicine this shift in authority is reflected in the notion of patients as experts in their own right, a construction which is not without its complications. As Segal (2009) says, "the problem is not just that laypeople do not know what doctors know; it is that they cannot know it" (p. It is an open question of what the construction of "expert patient" means and what the implications are. In my study, I found both medical expertise and experiential knowledge operating in e-health sites. For instance, a professional drug information sheet can only tell a patient so much about potential side effects of a drug. The act of reading patient reviews and seeing aggregated quantitative rankings of side effects provides an entirely different kind of information about a drug that patients can factor into their decision-making and their conversations with their doctors. It recognizes that technology, particularly new technologies, are a double-edged sword. This recommendation leads me to address some additional future research directions suggested by my study. Future Research As suggested by my study, the foremost area in which to conduct future research is patient-participatory sites. My dissertation has pointed to the novelty of these sites in terms of the ways they construct ethos, drawing on different values and sources of authority than traditional medical discourse. Future research might specifically examine sites that bill themselves as medical information sharing sites or medical crowdsourcing sites to better understand, rhetorically, this new and uniquely 195 contentious aspect of e-health. A deeper study of how companies persuade users to contribute data would be enlightening, and would offer a contribution to studies of online privacy. Along with study of data-sharing sites come additional ethical, legal, and methodological questions for researchers. Even sites that vaunt the value of open data may have limits on how it applies to external researchers. The growth of citizen science (or citizen medicine) initiatives, and professional or governmental boundary-keeping reactions, will also prove generative for rhetorical study. While deeper rhetorical analysis into one patient website or across different websites would be valuable, a multi-method approach would also be well suited to studies of trust and rhetoric. DePew (2007) argues that "we should try to avoid the separation of discourse from rhetorical situation, from rhetor and audience" (p. So, while a textual analysis is useful, a researcher would need to consult with participants to get at broader dimensions of user behavior such as motive and effect. In particular, interviews or surveys, or even observing a single user as they approach search engines, select sources, and make decisions based upon them, would be a very interesting complement to a rhetorical analysis of the sources. Besides studying health information in online, participatory contexts, technical communication scholars should attend to patient-participatory genres situated within medical institutions. Indeed, this dissertation is written at a time of great change not just in the e-health landscape but in medicine in general. Initiatives like OpenNotes, mentioned in Chapter 2, are catching on and requiring a rethinking of the audience for official medical documentation; the next step may very well be inviting patients to contribute to their own medical notes. According to one reporter, "the open records movement is moving beyond transparent, to interactive. On the flip side, a focus on the benefits of e-health and participatory medicine also raises the question of how it changes the medical experience for "non" e-patients. In this age of self-sufficient medicine, what happens to the patients who cannot or will not take on the burden of educating themselves? I have posed multiple directions that researchers could fruitfully explore regarding trust and e-health. In fact, I believe these issues need to be explored given the significant role that patients are playing in shaping e-health. Lay people are accessing, interpreting, exchanging, and communicating about complex technical and medical topics in brand new ways. These changes leave important questions wide open for researchers in rhetoric and technical communication.

Plague as a Biological Warfare Agent the first known attempt at what is now called "biological warfare" is purported to allergy forecast redwood city buy zyrtec 10 mg online have occurred at the Crimean port city of Caffa on the Black Sea in 1346 and 1347. The Tatar leader catapulted corpses of Tatar plague victims at the Genoese sailors. However, the disease was most likely spread by the local population of infected rats, not by the corpses, because an infected flea leaves its host as soon as the corpse cools. Medical officers need to consider this use of plague, particularly if the disease appears in an unlikely setting. Two human cases in the same county in 1995; animal surveillance on base began in 1996. Early experiments, however, demonstrated that aerial bomb dropping of bacteria had little effect because air pressure and high temperatures created by the exploding bombs killed nearly 100% of the bacteria. This flea is resistant to air drag, naturally targets humans, and can infect a local rat population to prolong an epidemic. Spraying fleas from compressed-air containers was not successful because high-altitude release resulted in too much dispersion and aircraft had to fly low for safety. However, clay bombs solved these technical difficulties and resulted in an 80% survival rate of fleas. Although no bombs were dropped, a strange mixture of wheat and rice grains, pieces of paper, cotton wadding, and other unidentified particles were observed falling from the plane. Unlike the zoonotic form of the disease that is typically observed, rat mortalities were not noted until months after the human cases. It was also observed that plague usually spreads with rice shipments (because rats infest the grain) along shipping routes, but the nearest plague epizootic was 2,000 km away by land or river. These unusual circumstances surrounding the plague outbreak suggest that it may have been of deliberate human origin. In November, bubonic plague appeared for the first time in the area where the particles had been dropped. On October 27, 1940, a Japanese plane was seen releasing similar particles over the city of Ningpo, in Chekiang province. Two days later, bubonic plague occurred for the first time in that city, resulting in 99 deaths in 34 days. Alibek states that "In the city of Kirov, we maintained a quota of twenty tons of plague in our arsenal every year. Other state-sponsored or extremist group efforts to obtain Y pestis will likely occur. For example, in 1995, a white supremacist and microbiologist fraudulently purchased vials of lyophilized Y pestis from the American Type Culture Collection. The genus was named in honor of Alexandre Yersin, the scientist who originally isolated Y pestis during a plague outbreak in Hong Kong in 1894; the species name pestis is derived from the Latin for plague or pestilence. Previous designations for this species have included Bacterium pestis, Bacillus pestis, Pasteurella pestis, and Pesticella pestis. The extensive genetic similarity (>90%) between Y pseudotuberculosis and Y pestis led to a recommendation that Y pestis be reclassified as a subspecies of Y pseudotuberculosis. The most recent molecular fingerprinting analysis of Y pestis suggests that this pathogen arose from Y pseudotuberculosis through microevolution over the past few millennia, during which the enzootic "pestoides" isolates evolved (see Biochemistry on next page). The pestoides strains appear to have split from Y pseudotuberculosis more than 10,000 years ago, followed by a binary split approximately 3,500 years later that led to the populations of Y pestis more frequently associated with human disease. The isola254 tion of Y pestis "pestoides" from both Africa and Asia suggests that Y pestis spread globally long before the first documented plague (Justinian) in 784 ce. Depending on growth conditions, Y pestis can exhibit marked pleomorphism with rods, ovoid cells, and short chains present. A gelatinous capsule, known as the F1 antigen, is produced by the vast majority of strains at 37°C. Y pestis is nonmotile, unlike the other mammalian pathogens of the genus that produce peritrichous flagella at growth temperatures lower than 30°C. Although Y pestis grows well on standard laboratory media, such as Plague a and the loss of one or more virulence plasmids. Biochemistry Y pestis is a facultative anaerobe, fermenting glucose with the production of acid. It is incapable of a long-term saprophytic existence, partly because of complex nutritional requirements, including a number of amino acids and vitamins.
