Leukocy to sis may reflect inflammation or abscess abdominal mass, rectal examination, and extraintestinal formation or may be secondary to corticosteroid therapy. Most commonly, there is Hyoalbuminemia may be due to intestinal protein loss one or a combination of the following clinical constellations. Chronic inflamma to ry disease-This is the most com� overgrowth, or chronic infammation.

Intestinal obstruction-Narrowing of the small bowel endoscopic findings include aphthoid, linear or stellate may occur as a result of infammation, spasm, or fbrotic ulcers, strictures, and segmental involvement with areas of stenosis. Patients report postprandial bloating, cramping normal-appearing mucosa adjacent to infamed mucosa. This may occur in patients 10% of cases, it may be difficult to distinguish ulcerative with active infamma to ry symp to ms (as above) or later in colitis from Crohn disease. Granulomas on biopsy are pres� the disease from chronic fibrosis without other systemic ent in less than 25% of patients but are highly suggestive of symp to ms or signs of infammation. Penetrating disease and fistulae-Sinus tracts that often is obtained in patients with suspected small bowel penetrate through the bowel, where they may be contained involvement. Penetration through the bowel can result in an may identif bowel wall thickening and vascularity, muco� intra-abdominal or retroperi to neal phlegmon or abscess sal enhancement, and fat stranding. Capsule imaging may manifested by fevers, chills, a tender abdominal mass, and help establish a diagnosis when clinical suspicion for small leukocy to sis. Fistulas between the small intestine and bowel involvement is high but radiographs are normal or colon commonly are asymp to matic but can result in diar� nondiagnostic.

Opera to rs still working 162 women garment workers and 76 women were compared to those who moved to other hospital workers such as nurses, labora to ry employment in 1991. There was a through a questionnaire asking type of machine low participation rate among the hospital operated, work organization fac to rs, workers. Eighty-six percent of the garment workplace design fac to rs, units produced per workers were sewing machine opera to rs and day, the payment system, and the duration of finishers (sewing and trimming by hand). The exposed to be significantly related to exposure, exposure garment workers likely had more repetitive time, or age, there was a significant drop-out jobs than most of the hospital workers. Subjects significantly higher when performing pear were selected after the bagging than when apple bagging. Confounders were not checked each day with a keyboard machine with a for in this study. Ekberg studies specifically asked about �precise repetitive movements� in their Yu and Wong [1996] chose to compare 90 questionnaire and controlled for confounders data entry, data processing, and computer and effect modifiers (age, gender, having pre programmers from an International Bank in school children) in their analyses. In the neck/shoulder area that were both objective same study, comparing the different and independent of the hand/wrist. Several of stereotypic, repetitive jobs in scissor-making, these studies [Baron et al. It is strictly on hand/wrist exposure and not arm, important to note that both the longer-cycled shoulder, or neck exposure. When comparing two groups in which for all work tasks and not specifically focused the level of repetitive exposure may not differ on the neck or neck/shoulder area. It can be used to establish a temporal relationship is reasonable to assume that in those studies, between exposure to repetitive work and neck given the exclusions required by the case or neck/shoulder disorders, the study by definitions, the onset of exposure was prior to Jonsson et al. Many more studies involved workers in introduction of new electronic cash registers repetitive work from a range of industries placed at unsuitable heights. Other studies excluded participants Repetition 2-11 Studies outside the epidemiologic literature give exposure assessments for their analyses and did supportive evidence that repetitive work is not conduct specific neck, shoulder, or upper related to neck/shoulder disorders. Nicholas [1990] reported in his exposure as strenuous work involving the upper discussion on pathophysiologic mechanisms of extremity that generates loads to the trapezius sports injuries that a low-load force with high muscles. Most of the studies that examined repetition results in a gradual deterioration of force or forceful work as a risk fac to r for tissue strength from strain to fatigue to neck/shoulder had several concurrent or deformation, with prefailure symp to ms, such as interacting physical work load fac to rs. Most studies that have dealt with force loading of the neck or stress generated on Conclusions Regarding Repetition the neck structures are from biomechanical the association between neck or studies performed in the labora to ry. In the epidemiologic studies reviewed, force is usually was found to be statistically significant in 19 estimated by either questionnaire, studies using different epidemiologic biomechanical models, in terms of weight lifted, approaches and under different circumstances electromyographic activity, or the variable, � of exposure. In terms of mean static trapezius load in assemblers was magnitude of the association, two studies had reduced from 4. Because so many interventions reported that the findings were statistically were involved in this study, it is not clear to significant at the p<0. However, interviews every 10 weeks to detect symp to ms musculoskeletal sick leave per man-labor years of muscle pain. Interviews concerning exposure at work were also conducted prospectively every 10 weeks Quantification of the muscle load was done by for 1 year. For the initial evaluation, Koskinen [1979] reported statistically observation of work sites were performed. Both studies controlled for age, gender, and length of employment in the Wells et al. Two of the four studies that used an increased load on the shoulder from a estimated hand and wrist exposure mailbag. Letter carriers were compared to gas measurement combinations of force and meter readers (without heavy loads) and postal repetition (but carried out no neck, shoulder, or clerks. A telephone survey was used to obtain upper extremity exposure measurements) found both symp to ms and exposure. In the Wells study, �time spent in physically heavy work before the confounding due to age, number of years on the present employment� appeared as a strong risk job, previous work experience, or quetelet fac to r for deterioration of health of the ratios was ruled out. This may lead to injury of occupational muscle-related disorders, such as these units, despite the fact that the to tal tension neck syndrome. This hypothesis was recently concerns stress on the trapezius and supported by a longitudinal study by Veiersted surrounding muscles of the neck from heavy et al.

Molecular Targeted Agents in Combination with Radia No published randomized clinical trials have compared tion. It should be noted that patients with oral cav ecules that modulate important signal transduction path ity carcinomas make up a minority of the studied popula ways. The ideal molecular targeted agent enhances radia ual patients with locally advanced carcinoma of the oral tion response but does not increase radiation side efects cavity, particularly those who are not candidates for surgery. Patients who are not candidates approach between the surgeon and the radiation oncologist. The objective of palliative treatment should be to alleviate symp to ms such as pain or bleeding. Along with the therapeutic efects of radiation are dose-dependent side ef fects (Box 2-15). Radiation-induced mucosi this and ulcers and the accompanying pain, xeros to mia, loss of taste, and dysgeusia are common side efects. Radia tion mucositis is a reversible condition that begins 1 to 2 weeks after the start of therapy and ends several weeks after termination of therapy. Oral candidiasis often accom � Figure 2-88 Postradiation scar in the foor of mouth, the site of the panies the mucositis. Permanent damage to salivary gland tissue situated in the beam path may produce signifcant levels of xeros to mia. Permanent Side Effects Xeros to mia Cervical caries during the postradiation period. Frequent use of water or Osteoradionecrosis artifcial saliva is of minimal beneft to these patients.

With the dry Focal alopecia ness also comes the potential for the development of cervi Focal hyperpigmentation cal, or so-called radiation, caries. This problem can be minimized with regular follow-up dental care and scrupu lous oral hygiene. Cus to m-ftted soft trays are made for the fully or partially dentate patient to permit the nightly ap plication of neutral pH fuoride directly to the teeth. This treatment is initiated at the start of cancer treatment and continues for the remainder of the patient�s life. It has been shown to signifcantly reduce the incidence of cervical caries and thereby the need for future dental extractions. Skin erythema is temporary, but the telangiectasias and atrophy that follow are permanent. Cutaneous pigmen tation in the line of therapy is also a late complication, and it, to o, may be permanent. A more insidious problem lies in the damage that radia � Figure 2-87 Radiation mucositis. Note erythema and multiple tion causes to bone, which may result in osteonecrosis mucosal ulcers. Poor nutrition and chronic alcoholism appear to be infuential in the progres sion of this complication. Also, if avail able, the use of a hyperbaric oxygen chamber may provide patients with a healing advantage. Because osteonecrosis is a danger that is always present after radiation, to oth extractions should be avoided after therapy. If absolutely necessary, to oth removal should be performed as atraumatically as possible, using antibiotic coverage. It is preferable to commit to a treatment plan that schedules to oth removal before radiation therapy begins. Prosthetic devices such as dentures and partial dentures, if carefully con structed and moni to red, can be worn without difculty. Continued careful surveillance of the patient�s oral health, during and after radiation therapy, helps keep complications to an acceptable minimum.
