| Signs of lymphedema stage 1: | 1. lymphedema disappears with bed rest and elevation. 2. soft, pitting edema 3. no or little fibrosis 4. no tissue changes 5. no Stemmer sign 6. dilated pre-lymphatic channels 7. small number of protein molecules in tissue space |
| Signs of lymphedema stage 2: | 1. edema is protein-rich 2. does not decrease with elevation 3. formation of connective and scar tissue (fibrosis) 4. pitting - non pitting (difficult to pit) 5. positive Stemmer sign 6. hardened edema (difficult to make indentation) |
| Signs of lymphedema stage 3: | 1. protein-rich, with connective and scar tissue formation 2. hardening of the papillomas of skin 3. significant increase in fibrosis (sclerosis) fatty deposit with deep sulci at joints 4. thickening of dermal tissue 5. protein is in ground substance and is interwoven with the collagen fibers (gel rather than solvent) 6. + Stemmer sign 7. firm and difficult to produce pitting |
| Diagnosis of lymphedema: | 1. use exclusion 2. volume assessment (3-4% increase in volume since last visit) 3. Stemmer's sign 4. Imaging (lymphoscintigraphy, MRI, CT, US) 5. Bioelectrical impedance (early stage) |
| Lipedema is a metabolic disease characterized by a significant increase in ___________ from iliac crests to the ankles. | subcutaneous fat. |
| T/F: Hyperplasia is present in lipedema. | T. |
| Swelling usually occurs in the ________ of the day because of the associated _______ edema and the diminished tissue resistance of fatty tissue. | the second half of the day associated with orthostatic edema |
| T/F: Lipedema is associated with decreased capillary ultrafiltration and vessel wall permeability. | F. (increased capillary ultrafiltration) |
| T/F: lipedema is hemorrhage free and non-painful. | F. It has frequent hemorrhage and is painful. |
