Upper limbs Ask the patient to sit with the arm supported on a table with the hand palm down On the ulnar aspect of the arm* measure with a ruler and record the distance from the nail bed of the little finger to 2cm above the ulnar styloid (wrist). This determines the starting point Mark the same point on the contralateral arm Lie a ruler along the ulnar aspect of the arm and mark the limb at 4cm intervals from the starting point to 2cm below the axilla With the limb in a relaxed position, measure the circumference at each mark, placing the top edge of the tape measure just below the mark Note measurements above the elbow in the correct section of the paper or electronic recording form Repeat the process on the other limb. Ensure there are the same number of measurements for both arms Document the position the patient was in when measurements were taken Lower limbs Ask the patient to stand or sit with both feet firmly on the ground On the medial aspect of the leg* measure with a ruler and record the distance from the floor to 2cm above the middle of the medial malleolus. This determines the starting point Mark the same point on the contralateral leg Seat patient on a chair with bottom as close to the edge as possible, or seat on a couch with the leg straight Lie a ruler along the medial aspect of the leg and mark the limb at 4cm intervals from the starting point to 2cm below the popliteal fossa for swelling below the knee If swelling extends above the knee, ask the patient to stand or to lie on a couch. Continue the marks at 4cm intervals above the knee to 2cm below the gluteal crease With the limb in a relaxed position, measure the circumference at each mark, placing the top edge of the tape measure just below the mark Note measurements above the knee in the correct section of the paper or electronic recording form Repeat the process on the other limb. Ensure there are the same number of measurements for both legs Document the position the patient was in when measurements were taken *If only one limb is affected, start with the unaffected side. The distance from the fixed anatomical point to the starting point should be recorded to ensure consistency when measurements are repeated subsequently. These methods differ from the techniques used to measure for compression garments, which are shown on pages 41 and 42. It is calculated from the ratio of from the skin surface dryness the highest ankle systolic pressure for each Papillomatosis: the development pigmentation limb to the highest systolic pressure in the of warty growths on the skin fragility arm. There are limitations to the test consisting of dilated lymphatics and fibrous tissue redness/pallor/cyanosis particularly in the presence of Lipodermatosclerosis: thickening warmth/coolness lymphoedema. The Stemmer sign is present and indicative of lymphoedema when a skin fold cannot be raised. Pain assessment Nutritional assessment Pain has been reported to affect 50% of patients with lymphoedema, with most Patients with lymphoedema should be taking regular analgesia14. However, lymphoedema is complex regional pain syndrome associated with obesity and obesity is a risk factitious swelling factor for the development of lymphoedema radiation-induced fibrosis after treatment for breast cancer40,41. The cancer recurrence/progression frequent co-existence of obesity and taxane chemotherapy lymphoedema suggests that obesity may degenerative joint disease. A reduction in waist circum environmental factors or psychosocial ference, indicating decreased central body fat, factors that affect patient experience and with no overall weight change may result in a ability to communicate pain39. Psychosocial assessment posture when sitting and standing will highlight areas that require referral for ability to put on and take off footwear/compression garments or bandaging specialist intervention and factors that may suitability of footwear have an impact on management and effect of lymphoedema on activities of daily living concordance with treatment. Patients with functional, joint or mobility problems should be referred as appropriate for physiotherapy and/or occupational therapy assessment. Patients and carers should have early active involvement in the management of lymphoedema. Patients the skin, treat any complications caused may require referral to a lymphoedema by lymphoedema and minimise the risk service (Box 15), or for assessment of co of cellulitis/erysipelas existing medical, functional or psychosocial risk reduction to avoid factors that may problems. Successful management of exacerbate lymphoedema lymphoedema relies on patients and carers pain and psychosocial management. During this time treatment should be Patients should be reviewed four to six evaluated continuously and appropriate weeks after initial fitting, and then after alterations made according to patient need three to six months if response is and the effectiveness of the selected satisfactory. Appropriate training is required for at each garment renewal, ie approximately all practitioners who deliver intensive every three to six months. Management should the practitioner will be appropriately change trained at specialist level. A recent review concluded that involvement is suspected, assessment and to a practitioner with immediate ambulation with appropriate referral to a vascular specialist training. This includes patients with venous ulceration who have painful, medical those with: poor mobility and are unable to elevate their moderate concurrent lower limb legs52-54. Patients tolerate the pressures given here are sub who wear compression cancer requiring palliative treatment bandage pressures measured at the garments can use one of co-morbidities requiring less aggressive ankle in the supine position. In the palliative situation, bandages may be used to support the limb and would apply very little compression. Lower pressure compression garments also have a role to play in managing symptoms in a palliative context. In the developed that is comfortable and intensive phase of treatment, daily acceptable to the patient. Patients should, wherever the practitioner will be appropriately possible, be actively engaged in all stages of trained, and have access to physiotherapy their treatment. Patient involvement during assessment and to a practitioner with the transition phase, with education, specialist training. A trained and competent health or social carer or a relative can support any or all of these activities.

Most patients with the long-term management of Long-term management of lymphoedema lymphoedema who lymphoedema focuses on enhancing the usually involves compression garments. Success relies long-term will be bandaging (Figure 10) or a on self management by patients and carers, combination of compression garments and with appropriate and effective education, bandaging. It involves: lymphoedema who have developed daily skin care expertise in managing their condition will be exercise/movement able to manage their lymphoedema mainly compression compression garments, through exercise, using compression bandaging or an inelastic adjustable garments when needed. Careful monitoring for signs of neck, trunk, breast or genitalia, can be infection and scrupulous skin care are the individually tailored particularly challenging, especially because crucial. Management will require Women usually require custom made compression bandaging, collaboration with the patient and a compression garments with anatomically compression garments and multidisciplinary team. In some contoured stasis pads to treat thickened and individualised foam pads circumstances, care may be managed swollen areas. Lymphoedema can affect the chest, back, shorts) may be a useful alternative to ready abdomen, buttocks, breast or genitalia in to wear or custom made scrotal supports or isolation or in combination with limb compression garments. Consequently, Lymphoedema of the head and neck is often particular attention should be paid to a complication of cancer or secondary to determining the presence or recurrence of tissue damage in this area. Low pressure the management strategies described for compression may be applied using breast and genital lymphoedema can be bandaging or custom made garments. Low combined, where necessary, with those for density foam pads can be used to apply the management of limb lymphoedema56. Surgical Breast lymphoedema management of eyelid lymphoedema may be There is little consensus on the best considered. Medium compression may be applied using suitable bras (including sports bras), Lycra foundation garments or custom made garments. Swelling may produce deep bath oils, soap substitutes or moisturisers skin folds where fungal and bacterial (lotions, creams and ointments). Reduced tissue the best method of emollient application compliance may further compromise lymph is unknown. Ordinary soaps, which usually component of compression garments, and it contain detergents and no glycerin, should is preferable to avoid application be avoided because they tend to dry the skin. In high Following are descriptions of skin care concentrations, mineral and petrolatum regimens for skin conditions that can occur based products may exacerbate dry skin in patients with lymphoedema. These conditions by occluding skin pores and conditions may occur simultaneously and preventing natural oils from surfacing. Any Emollients with a low water content are sign of bacterial infection should be recommended. Nail underlying lymphoedema and improves skin infection requires treatment with an oral condition.

Below is a list of suggested items that can make your life easier and keep you safe. Most of the items can be found at a medical supply store or at pharmacies, home improvement stores, or thrift stores. These items should be purchased before your surgery, however before buying; we suggest you talk to either a physical or occupational therapist about your specific needs. Personal Aids Walker (with 5 inch wheels, not a Rollators or walker with seat) Cane Reacher (or grabber) Crutches Sock aid Long-handled shoehorn Elastic shoe laces Bathroom Elevated commode seat Toilet seat riser Shower chair Grab bar for shower / tub Hand-held shower head Long-handled bath sponge 9 Before Your Surgery Checklists the following checklists are guides to help you prepare for surgery and recovery. If I have not received my schedule with in two weeks before my surgery, I will contact the surgery scheduling office. Pre-Admission Testing A pre-operative work-up is mandatory for all joint replacement patients. At this visit, you will be asked about your medical history, previous surgeries, illnesses and current state of health. You will be told which medications to take the morning of surgery with a small sip of water. Bathing helps reduce the amount of bacteria on the skin and may lessen the risk of infection after surgery. The Day of Surgery On the day of surgery, you must remember several important things: Take only the medications you have been told to take; take them with a small sip of water. Regional Anesthesia numbs a part of your body with an injection of local anesthetic. For total joint replacement surgery of the knee and hip, regional anesthesia may involve injections into your back or around the nerves in your leg or hip. Remember to tell the anesthesiologist (or nurse anesthetist) if you prefer to be asleep or want to stay awake. While you are in the operating room, your loved ones may wait in the surgical waiting room. The surgeon or representative will speak with your family while you are recovering. It is normal to drift in and out of sleep until the anesthesia completely wears off. While in your hospital room, your nurse will: Monitor your vital signs frequently. Although getting up on the day of surgery aids in your recovery and helps prevent complications. Within 24 hours after arriving to your hospital room you will receive a visit from a physical and/or occupational therapist to begin mobility exercises. Although you may feel significant pain during and after your therapy sessions, it is necessary for your recovery. Your physical therapist will teach you how to: Lay in your bed in comfortable positions. Your occupational therapist will teach you how to: Comply with hip or knee precautions while performing functional activities Perform transfer techniques, such as getting on and off toilet seat with and without assistance or getting into and out of a car. Total Joint Precautions While recovering from surgery, you will follow specific precautions provided to you by your therapists. These precautions allow you to heal properly and help prevent potential complications. Make sure to ask your surgeon when it is safe to stop following these precautions. General precautions are as follows: Do not bend your operated leg beyond a 90 degree angle. We encourage you to get up for meals, go to the bathroom, and get out of bed all with assistance. While in the hospital, we will ask you to rate your level of pain several times a day. This medication, also called an anti-coagulant, lessens the chance of harmful clots forming in your blood vessels. Your Hospital Discharge Discharge planning starts the moment you decide to have surgery. One of the first things you need to do is arrange a ride for the day of your discharge. Most patients are ready to be discharged from the hospital one to three days after surgery; however, specific criteria must be met. You will be discharged from the hospital when: Your medical condition is stable. If you have not met the criteria to be discharged home, you will be discharged to a skilled nursing facility. You should expect less pain, stiffness and swelling, and a more independent lifestyle. Returning to work depends on how quickly you heal and how demanding your job may be on a new joint. After you are discharged from the hospital or rehab facility, there will be a few weeks before you return for a follow-up visit with your surgeon. This period of time is critical in your rehabilitation and for positive long-term results from your surgery. If you need more pain medication, you must give a three day advance notice before you run out medication. Also remember: You are not permitted to drive a car while taking narcotic pain medication. Before you go home, your surgeon or nurse will explain how to take care of your wound and when to remove your dressing. Make sure you understand these instructions before you leave the hospital and who to contact if you need assistance. Note: How to care for your wound is included in your hospital discharge instructions. Call your surgeon immediately if you notice any increase in drainage, redness, warmth, or have a fever above 101 degrees Fahrenheit for more than 24 hours. Walker, Crutches, Cane Use your assistive devices for balance as instructed by your surgeon or therapist. By your first post-op visit with your surgeon, you may have already improved and changed from using a walker or crutches to a cane (as recommended by your surgeon or therapist). You will likely experience anxiety and question whether you were discharged too early. Also expect a visit from the physical therapist or occupational therapist within 48 hours of discharge. Activity Continue your exercise program and increase activity gradually; your goal is to regain strength and function. If this occurs, elevate the leg above the level of your heart (place pillows under the calf, not behind the knee joint), and apply ice directly to the knee. You may continue with elevation and icing as needed to help decrease swelling and discomfort. Based on your needs, your therapy may be continued at home or in an outpatient setting of your choice. Frequent, short walks?either indoors or outdoors? are the key to a successful recovery. You may experience discomfort in your operated hip or knee, and you may have difficulty sleeping at night. You may be a passenger in a car, but you should sit on a firm cushion or folded blanket to avoid sitting too low. See the instructions at the end of this guide for specific information for getting in and out of the car. You or a family member can call and receive answers to general questions as well as instructions in the event of an emergency. During the first six weeks after discharge, you should be making progress week by week. Most patients are eager to report their progress at follow-up visits and are ready to move to the next level in their recovery. Most patients can accomplish the following during the first six weeks after total joint replacement: Walk without help on a level surface with the use of walker, crutches, or cane as appropriate. This is approved on an individual basis and should be discussed with your surgeon. Swelling can cause increased pain and limit your range of motion, so taking steps to reduce the swelling is important. Sexual Activity After Joint Replacement Many people worry about resuming sexual activity after a joint replacement. Hip Generally, it is safe to resume sexual activity six weeks after surgery as long as there is not significant pain. Initially, being on your back will be the safest and most comfortable positioning. Please discuss any specific concerns with your physical therapist or advance practice nurse. During the healing process, the body needs increased amounts of calories, protein, vitamins A and C, and sometimes, the mineral zinc. Eat a variety of foods to get all the calories, proteins, vitamins, and minerals you need. What you eat can help heal your wounds and prevent infection and potential complications. If you?re not eating well after surgery, contact your healthcare provider about nutritional supplements. Weeks 6 to 12 at Home this period after joint replacement is a time of continued improvement. You will probably notice an in crease in energy, a desire to do more activities, and a noticeable improvement in your new joint. Please keep in mind that every patient is different and will improve at different pace. Walking After your six-week follow-up visit, you will likely start using a cane to walk and move about. Tips to remember for returning to work include: Avoid heavy lifting after you return to work. However, exercising is the most important activity to increase strength and leads to the best outcome. Comply with all Restrictions Although you are feeling back to normal, it is important to understand and follow the restrictions your surgeon discussed with you.

A summary of the fndings on the extent and pattern of herbicide spraying (Stellman et al. In those publications the researchers argued that it is feasible to conduct epidemio logic investigations of veterans who served as ground troops during the Vietnam W ar. The report concluded that ?despite the short comings of the exposure assessment model in its current form and the inherent limitations in the approach, the committee agreed that the model holds prom ise for supporting informative epidemiologic studies of herbicides and health among Vietnam veterans and that it should be used to conduct studies? (p. This model has since been used in analyses of the Korean Veterans Health Study (Yi and Ohrr, 2014; Yi et al. They suggested that dermal exposure through both direct deposition and post-application transfer from foliage could be derived from application information such as aircraft speed and altitude, from nozzle characteristics, and from droplet evaporation and environmental parameters such as canopy density, canopy roughness, and crosswind speed. The authors did not consider exposures resulting from contact with soil and dust or through inhala tion because they considered these routes to be negligible (Ginevan et al. However, subsequent reviews of the methodology underlying the authors? analyses (S. Stellman, 2014, 2015) found several weaknesses that call the results by Ginevan et al. Estimating the magnitude of risk of each particular health outcome among herbicide-exposed Vietnam veterans requires quantitative information about the dose?time response relationship for the health outcome in humans, information on the extent of herbicide exposure among Vietnam veterans, and estimates of individual exposure. Few, if any, studies either in humans or in experimental animals have examined those interactions. The requisite information is still not available despite concerted efforts to use modeling to re construct likely exposure from records of troop movements and spraying missions (J. Prior committees have thought it unlikely that additional information or more sophisticated methods would permit any sort of quantitative assessment of Vietnam veterans? increased risks of particular adverse health outcomes that are attributable to exposure to the chemicals associated with herbicide spraying in Vietnam. Accordingly, the lack of exposure estimations for Vietnam veterans will likely remain a hurdle to epidemiologic studies, and unless this issue is resolved, the potential for additional epidemiologic studies to yield improved information regarding the specifc question of whether an associa tion exists between herbicide exposure and health outcomes will remain limited. Veterans and Agent Orange: Update 11 (2018) 3 Evaluation of the Evidence Base this chapter describes the approach and methods that the committee used to identify and evaluate the scientifc and medical literature on exposures to herbi cides that occurred in U. The frst part of this chapter details the methodology used to identify and screen the literature. The second part of the chapter details the evaluation criteria used to review the relevant studies, including the types of studies considered, the health outcomes considered, and the categories of association used to draw conclusions about the strength of the evi dence of possible health effects resulting from herbicide exposure. The committee also describes some of the issues it encountered when reviewing the literature on Vietnam War exposures and health outcomes, such as multiple exposures and in dividual variability. To begin, the committee oversaw extensive searches of the scientifc literature using a strategy adapted from prior committees? literature search methodology (see Box 3-1). For this update, electronic searches of the medical and scientifc literature were carried out on four databases: Web of Science, Scopus, Medline, and Em base. The four searchable databases index biological, chemical, medical, and toxicological publications. The full texts of the articles were searched so that if any of the search terms was included in the title or abstract or indexed in the key words or text of the article (excluding the cited references section), the article would be included in the results of the search. Using the search terms in Box 3-1, the databases were searched in two phases, with the searches spanning over timeframes that were extended from those used in prior updates. In the spring of 2017, the databases were searched for articles published between January 1, 2014, and March 31, 2017. Then in early February 2018 the databases were again searched for any articles with the relevant search terms published between March 1, 2017, and December 31, 2017. Other than dates, no limitations (such as language, populations, or species) were put on the search. In addition, potentially relevant articles were also identifed by searching the reference lists of relevant review and research articles, books, and reports. Exact duplicate articles and those that had been summarized and referenced in Update 2014 were deleted. The committee became aware of a few studies that reported updated fndings on relevant exposed populations (such as the Seveso, Italy, cohort and New Zealand phenoxy herbicide producers) published following the December 31, 2017, search cutoff and reviewed these studies as well. The frst search produced in excess of 12,000 ?hits,? and the second search identifed more than 1,600 articles of potential relevance. Article titles and abstracts were screened for relevance by committee members and the Health and Medicine Division staff to determine which studies should be considered for full-text retrieval using the criteria in Box 3-2. The current committee expands upon that perspective by placing it in a framework that underscores the relevance of the concepts of multifactorial causa tion, the literature on which has recently begun to mature and offer new insights. The statistical interactions of risk factors, which can have synergist or antagonistic effects, can result in ef fects of combined exposures that would not have been predicted based on their independent impacts. An example of a synergistic interaction is the association with lung cancer from combined exposures to workplace arsenic and smoking: in this case, the risks from arsenic are much higher among smokers than among non-smokers (Hertz-Picciotto et al. Disentangling the separate effects of combined exposures or risk factors in relation to a particular outcome does raise serious challenges, however, and it may indeed be infeasible when the correlations among those exposures are ex ceedingly high, to the point of inseparability, or when suffciently large studies cannot be conducted. Exam ples include exposure to herbicides containing organophosphates (not otherwise specified), atrazine, paraquat, glyphosate, m etam ifop, rotenone, clarityon, and diuron; and exposure to pesticides and insecticides. Inorganic ar senic and benzene were not considered as relevant service-related exposures among Vietnam veterans and were not evaluated in relation to their potential risk of adverse health outcomes. Thus, a nuanced and comprehensive approach to combined exposures is critical to understanding causation. Underlying susceptibility is not always ge netic, but can instead be a prior or concomitant exposure, and thus the possibility of multifactorial causation requires paying attention to confounding as well as to interactions. Very few epidemiologic studies on exposure toV picloram or cacodylic acid have been published, which is another reason for the committee to consider metabolites of these compounds. However, the biologi cally active compound benzene does not emerge from dioxin, whose three-ring structure is extremely stable and resistant to metabolism. The combinations of the chemicals with other agents that might lead to problems are virtually infnite, and hence, not feasible for systematic and comprehensive evaluation. Real-life experience, as investigated with epidemiologic studies, effectively integrates any results of exposure to a target substance in combination with other substances that may be etiologically relevant. As explained, inorganic arsenic and benzene were not considered as relevant service-related exposures among Vietnam veterans and thus were not evaluated in terms of their risk for adverse health outcomes. The committee only included literature that had undergone peer review or government reports and invited presentations that were provided to the committee, under the assumption that they have been carefully reviewed. The process of peer review by fellow professionals increases the likelihood that high-quality studies will appear in the literature, but it does not guarantee the validity of any particular study or the ability to generalize its fndings. For example, numerous case-control studies characterized exposure to pesticides or herbicides on the basis of job titles, farm residence, or longest-worked industry. For instance, this rubric would apply to any published articles from the Agricultural Health Study because 2,4-D was one of the most frequently used pesticides in this large prospective cohort, but some results have lumped all herbicide exposure together. Studies with original data collection and analyses were preferred over stud ies that were re-analyses of a population (without the incorporation of additional information), pooled analyses or meta-analyses, reviews, and so on, and the former are the type of evidence that the committee preferentially considered when assessing the strength of association between herbicide exposure and a health outcome when drawing its conclusions. W hile studies of the latter type may be informative and may be discussed in conjunction with primary results or in synthesis sections on a given health outcome, they are not themselves part of the evidence dataset and therefore were not considered in the fnal count of new literature considered in this volume. The committee has endeavored to express its judgments as clearly and precisely as the data allow. Full text was then obtained for any articles that were considered potentially rel evant based on their titles and abstracts and after applying the inclusion and ex clusion criteria. Full-text articles were distributed among the committee members based on their areas of expertise, with at least two committee members reviewing each paper. Because of the variability in the descriptions and diagnoses of the health conditions considered in this report, the committee made no a priori assumptions about the usefulness of any article or report for a health outcome. Each study was reviewed and objectively evaluated for each health outcome it presented. If a study examined more than one health outcome, it was considered separately for each of those outcomes. After reading, if the full text revealed that the study met one of the exclusion criteria (see Box 3-2), it was excluded from further consideration. After review of the full text of the identifed articles, studies that were con sidered relevant (165 epidemiologic studies and nearly 100 toxicologic studies) were discussed and evaluated thoroughly, and are included in this report. The responsible committee members then presented the information from each new relevant study?including the methods used for selecting the study populations and conducting the research. Based on the details of exposure and the description of how exposure was measured, an epidemiologic study was classifed either as a primary article, in which case it was given full evidentiary weight, or as a second ary article, in which case it was reviewed and more briefy described under the heading of ?Other Identifed Studies. An epidemiologic study was also clas sifed as secondary if the outcome was a biologic marker of effect as opposed to a recognized condition or disease. Mechanistic and toxicologic studies contributed to the evidence for biologic plausibility but were not considered primary studies, so that based on those studies alone, their weight would not be enough to change the level of evidence of an association. The toxicologists on the committee provided a summary of previous and new mecha nistic or toxicologic studies for that health outcome. When drafting language for a conclusion, the committee considered the nature of the exposures, the nature of the specifc health outcome, the populations exposed, and the quality of the evidence examined. The draft text was reviewed and discussed in further plenary sessions until all committee members reached a consensus on the description of the studies and the conclusion for each health outcome. The committee did not use a formulaic approach to determining the number of primary or supporting studies that would be necessary to assign a specifc category of association. If no new primary studies for a health outcome were identifed, the evidence table from Update 2014 was included. Effect estimates, data, and units of measure are presented as reported in the cited studies, except where otherwise noted. The committee did not collect original data, nor did it perform any secondary data analyses, such as meta-analyses. Epidemiologic studies effectively integrate any results of exposure to a target substance in combination with other substances that may be etiologically relevant. Several types of epidemiologic studies were evaluated, including cohort, case-control, and cross-sectional designs. The committee weighed the importance of the epidemiologic studies in the following order: Vietnam veterans, occupationally exposed workers, and people who were exposed environmentally. Including these more highly exposed populations had the additional advantage that epidemiologic studies of them were likely to have greater statistical power to detect any adverse effects that might occur with exposure. Toxicologic studies, particularly in animal models, are included to inform the understanding of biologic plausibility through the toxicology of the chemicals and their exposure pathways. Instead, having served in Vietnam or participating in the Agent Orange Registry is often considered a proxy of her bicide exposure. Therefore, it is diffcult to quantify the risk of specifc health outcomes when the exposures of the total at-risk population have not been mea sured or estimated. In the absence of actual measures of exposure, comparisons between deployed and non-deployed Vietnam-era veterans are considered the next most relevant comparison. Moreover, in many studies of Vietnam veterans, not all health outcomes of interest were reported (in some cases there were too few cases to report, only specifc health outcomes were of interest, or the veteran population was too young for a particular manifestation).
