Manipulative therapy of secondary lymphedema in the presence of locoregional tumors

CANCER, Issue 4 2008
Ximena A. Pinell BA
Abstract BACKGROUND. Complete decongestive therapy (CDT), including manual lymphatic drainage (MLD) is a manipulative intervention of documented benefit to patients with lymphedema (LE). Although the role of CDT for LE is well described, to the authors' knowledge there are no data regarding its efficacy for patients with LE due to tumor masses in the draining anatomic bed. Traditionally, LE therapists are wary of providing therapy to such patients with ,malignant' LE for fear of exacerbating the underlying cancer, and that the obstruction will render therapy less effective. In the current study, the authors' experience providing CDT for such patients is discussed. METHODS. Cancer survivors with LE were referred to therapists at 2 Atlanta-area clinics. CDT consists of treatment (Phase 1) and maintenance phases (Phase 2). During Phase 1, the patient undergoes manipulative therapy and bandaging daily until the LE reduction plateaus; at that point, Phase 2 (self-care) begins. At the beginning and end of Phase 1, LE is quantified and differences in girth volume calculated. The results for patients completing Phase 1 therapy for LE in the presence of locoregional masses were compared with results for patients with LE in the absence of such disease. Both volume reduction of the affected limb and number of treatments to plateau were analyzed. RESULTS. Between January 2004, and March 2007, LE of 82 limbs in 72 patients was treated with CDT and Phase 1 was completed. The median number of treatments to plateau was 12 (range, 4,23 treatments); the median limb volume reduction was 22% (range, ,23 to 164%). Nineteen limbs (16 patients) with associated chest wall/axillary or pelvic/inguinal tumors had nonsignificant difference in LE reduction (P = .75) in the presence of significantly more sessions to attain plateau (P = .0016) compared with 63 limbs in 56 patients without such masses. CONCLUSIONS. Patients with LE may obtain relief with CDT regardless of whether they have locoregional disease contributing to their symptoms. However, it will likely take longer to achieve that effect. Manipulative therapy of LE should not be withheld because of persistent or recurrent disease in the draining anatomic bed.

Interactional Input and The Incorporation of Feedback: An Exploration of NS,NNS and NNS,NNS Adult and Child Dyads

LANGUAGE LEARNING, Issue 1 2003
Alison Mackey
Given the documented benefits of participation in communicative interaction (e.g., Gass & varonis, 1994; Mackey, 1999), the present study investigated the effects of interlocutor type on the provision and incorporation of feedback in task,based interaction. The interactions of 48 dyads, evenly divided among adults and children, and native speaker,nonnative speaker and nonnative speaker,native speaker, were analyzed to assess the effect of interlocutor on (1) amount of feedback, (2) opportunities for modified output, and (3) immediate incorporation of feedback. In all dyed types, at least 30% of errors resulted in feedback, much of which led to modified output. Analyses also revealed significant differences for amount, nature, and response to feedback according to dyad type. [source]

Physiological and performance effects of glycerol hyperhydration and rehydration

NUTRITION REVIEWS, Issue 12 2009
Simon P Van Rosendal
Studies have shown that beverages containing glycerol can enhance and maintain hydration status and may improve endurance exercise performance by attenuating adverse physiological changes associated with dehydration. Improvements to performance include increased endurance time to exhaustion by up to 24%, or a 5% increase in power or work. However, some studies have found no performance benefits during either prolonged exercise or specific skill and agility tests. In studies that have shown benefits, the improvements have been associated with thermoregulatory and cardiovascular changes. These include increased plasma volume and sweat rates, as well as reduced core temperature and ratings of perceived exertion. In a very small number of subjects, glycerol consumption has been associated with side-effects including nausea, gastrointestinal discomfort, dizziness, and headaches. In summary, while glycerol and fluid ingestion results in hyperhydration, the documented benefits to exercise performance remain inconsistent. [source]

Understanding fire fighting in new product development,

THE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 5 2001
Nelson P. Repenning
Despite documented benefits, the processes described in the new product development literature often prove difficult to follow in practice. A principal source of such difficulties is the phenomenon of fire fighting-the unplanned allocation of resources to fix problems discovered late in a product's development cycle. While it has been widely criticized, fire fighting is a common occurrence in many product development organizations. To understand both its existence and persistence, in this article I develop a formal model of fire fighting in a multiproject development environment. The major contributions of this analysis are to suggest that: (1) fire fighting can be a self-reinforeing phenomenon; and (2) multiproject development systems are far more susceptible to this dynamic than is currently appreciated. These insights suggest that many of the current methods for aggregate resource and product portfolio planning, while necessary, are not sufficient to prevent fire fighting and the consequent low performance.
