If parasites can be considered as promising sentinels, we need reasons for the establishment of ' new ' indicators. Of 185 sentinels recovered, 2n7 % had single-species infections. Using the adjoint problem, one shows that the existence of these sentinels is reduced to the solution of exact controllability problem with constraints on the state. They are certainly sentinels of the environment in which we live because dogs generally share that environment, sometimes very closely indeed.

The study included 708 patients with clinically palpable breast carcinomas and no palpable axillary adenopathy, who underwent lumpectomy (with no sentinel or axillary node dissection). Then the existence of the sentinel (6)-(9) holds if and only if null controllability problem with constraint on the control (20)-(23) holds.

Routine type-specific serology has not yet been performed on serum samples collected from sentinel animals in 1996 and 1997. Many papers discuss critical incident reporting (how to report and analyse sentinel events) but provide no evidence that patient care improves as a result. Because dogs are ten times more likely to become infected from the environment than humans, they are considered to be sentinels for the disease. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Blood samples, taken from an ear vein, were collected from all sentinel animals. Up to now, only limited information is available of the use of sentinel node biopsies after preoperative chemotherapy. Should positive sentinel node cases have a further axillary dissection? When the sentinel node is positive, a variety of factors need to be appreciated to make decisions regarding subsequent axillary dissection. A sentinel sits atop the hill behind the house, to be formed from a concrete spiral. However, the role of sentinel lymph node biopsy after neoadjuvant chemotherapy is still controversial. Firstly, fly traps and sentinel animals sample different fractions of the fly population. Ghosts often appear in the narrative as sentinels or prophets of things to come.

The usual identification rate of the sentinel lymph node is greater than 85 percent, whereas false-negative analyses are generally less than 10 percent. The patient recovered uneventfully from her surgical excision and sentinel lymph node biopsy. Either sentinel or axillary lymph nodes biopsy is employed to determine the extent of the regional spread (staging).

If the change counter is greater than zero, an intermittency factor is computed dividing the change counter by some user-defined sentinel window. The family is the child's first social group and can be the first sentinel detecting early signs of later possible problems. Oviposition on sentinel cattle occurred mostly in late afternoon or early evening but increased significantly as the wound aged. Similar analyses were performed on the sentinel oviposition data. One uninoculated sentinel rabbit per trial was housed in the same room as the virus-inoculated rabbits to test for horizontal transmission of the virus. There remain vestiges of the sentinels' places of rest and observation. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A particular sentinel event might be chosen to highlight a breakdown in patient safety. Efficient assessment of filariasis endemicity by screening for filarial antigenaemia in a sentinel population. Consistent differences in oviposition rates on sentinel cattle at different localities on the cattle station suggested the existence of highly clumped, quasi-stationary populations. In contrast to sentinel species, gregarious nuclear species can also positively affect the foraging efficiency of other flock participants.

Sentinel's ego and recent rise in ranks gets the better of him. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. To compensate for occasions when less than six sentinels were available, oviposition rates were analysed as egg masses per sentinel per day. Should sentinel lymph node biopsy be performed before or after neoadjuvant chemotherapy? Therefore, a sentinel procedure could be done, especially when prior surgery was performed more than 6-12 month previously. The safety of sentinel lymph node biopsy in pregnancy is unknown. Preoperative lymphoscintigraphy during lymphatic mapping for breast cancer: improved sentinel node imaging using subareolar injection of technetium 99 m sulfur colloid. Surgical resection and radiolocalization of the sentinel lymph node in breast cancer using a gamma probe. Preparing the "soil": the primary tumor induces vasculature reorganization in the sentinel lymph node before the arrival of metastatic cancer cells. Patients will benefit because of the well-controlled use of the sentinel lymph node mapping and the avoidance of unnecessary axillary dissection. Therefore, additional significant disease may remain in the axilla after a positive sentinel lymph node. Over 200 patients in each group did not have axillary dissection or sentinel lymph node biopsy. Prior to the beginning of the surveillance, sentinel clinicians were given instruction on the reporting procedure by the coordinator of the surveillance. A sentinel study on the incidence of gastroenteritis in general practices was carried out in the years 1992-3. A 24 h hot-line was set up during the surveillance period for the sentinel clinician to be able to report unexpected incidents at anytime. An evaluation of the treatment success of the national programme was accomplished through sentinel stool surveys from a sample of the population before and after each drug administration. Biomarkers of immunotoxicity in fish and other non-mammalian sentinel species : predictive value for mammals ? Lymphatic mapping and sentinel lymph node biopsy in early-stage breast carcinoma: a metaanalysis. Thirdly, the observed increases in fly activity over time, both in respect of baited trap catches and oviposition rates on sentinel cattle, suggests the possibility of designing an improved lure. Several studies, mainly from single institutions, have found varying identification (84.3-93.5%) and false-negative (0-33%) rates in patients who underwent sentinel lymph node biopsy after neoadjuvant chemotherapy [30-36]. On this background, of course, the introduction of sentinel node biopsy has been possible, particularly as a method of avoiding axillary dissection entirely in patients that have negative sentinel nodes. The initial breast surgery could be a lumpectomy or mastectomy as such or in combination with the removal of the axillary nodes or a sentinel procedure. Core species often have striking plumage and calls that attract other birds; they are often also known to be very active sentinels, providing warning of would-be predators.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Though sentinel reporting may overestimate the proportion of cases in older age groups (due to a larger proportion consulting their physicians), most consultations are for childhood infection. If this hypothesis is correct, women with sentinel lymph nodes found on careful histopathologic analysis to be negative may be spared the morbidity of axillary lymph node dissection. Indications for the sentinel node: multicentric, size of tumor, prior surgery 25. Current status of sentinel lymph node mapping and biopsy: facts and controversies. However, it should be noted that type-specific serology was not completed on the sentinel cattle in 1996 and 1997 where efforts were largely directed towards virus isolation. Nevertheless, in order to detect micrometastatic tumor defined as 2-mm deposit, it is reasonable to assume that sentinel lymph nodes should be sectioned at 2-mm intervals. The first sentinel group of 30 animals was sampled at intervals of one to three weeks but subsequent sentinel groups were sampled regularly at weekly intervals. Lymphatic mapping and sentinel lymphadenectomy for breast cancer. Increasingly, however, the need for axillary dissection, even after a positive sentinel node biopsy, should be seriously questioned, and will be abandoned entirely over the next few years [24]. A randomized trial of axillary dissection versus no axillary dissection for patients with clinically node-negative breast cancer and micrometastases in the sentinel node. However, it may be relevant that the adjoining pastures were usually stocked with young cattle whereas at the other sentinel sites, surrounding pastures were mainly grazed by mature animals. However, due to their very long life span, tens of thousands of these silent sentinels are still protecting transmission lines and electrical apparatus all over the world. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Among these parasites cestodes and acanthocephalans in particular have an enormous heavy metal accumulation capacity exceeding that of established free living sentinels. On the first occasion, six sentinels were deployed, and on the second, only five sentinels were available. We prove the existence of such sentinels by solving a problem of null controllability with constraint on the control. The 1991 and 1993 releases (above), totaling 1400 putatively uninfected snails (sentinels), assessed the probability of a snail becoming infected while in the field. Therefore, it is necessary to evaluate if acanthocephalans meet the criteria commonly accepted for sentinels. An overview of sentinels is provided, together with a thorough discussion of the main problem of where to place them. The sentinels just had to complete a simple form and send it by fax to the local health institutes at the end of each day. Summary reports were distributed to all sentinels and health authorities on a daily basis. Another problem with symptom-based surveillance is in defining the area of surveillance and the number of sentinels required. Macrophages are critical sentinels of the immune system and may influence immune responses to spaceflight in vertebrates. Reports and surveys "sentinels" stop the bacteria from identifying the message as an invading virus and destroying it. The value of parasites as accumulation indicators for heavy metals in environmental monitoring will be discussed in the present review and thoroughly compared with that of established free living sentinels. In fact, on the starting day, we asked that name of school or office of patient should be added to the last column and sentinels readily followed our requests. Our system was simple, and the sentinels were experienced and actively interested in contributing to the surveillance, meaning that the system could be adjusted with relative ease.
