Estimates for Assessment of Lymphedema: Reliability and Validity of Extremity Measurements.

Measuring lymphedema with high accuracy is important for several reasons. The aim of this study was to assess the reliability and validity of three routinely used methods to estimate limb volumes. Inverse water displacement, girth measurements, and Perometer measurements were executed.

[A man with blisters after a knee replacement].

Lymphedema-distichiasis syndrome: a distinct type of primary lymphedema caused by mutations in the FOXC2 gene.

Lymphedema-distichiasis syndrome (LD, OMIM 153400) is an autosomal dominant disorder with variable expression. It is caused by mutations in the FOXC2-gene, which codes for a forkhead transcription factor involved in the development of the lymphatic and vascular system. LD is characterized by late childhood or pubertal onset lymphedema of the limbs and distichiasis (double row of eyelashes).

Lymphedema in Prader-Willi syndrome.

A 20-year-old woman with Prader-Willi syndrome presented with heaviness and swelling in the lower legs and feet, which had developed after a fall. Lymphoscintigraphy showed a disturbed lymphatic drainage pattern in both lower extremities. Based on the clinical findings and the results of lymphoscintigraphic examination we made the diagnosis of lymphedema.
