Pain is an important criterion for diagnosing lipedema. This pain, however, has not been properly investigated or characterized in the literature, and in most cases, authors have settled for putting forward hypotheses. Comparison of these hypotheses with actual findings, if even available, it becomes obvious that many of these hypotheses cannot be correct. Hardly any of the tangible results seem to provide a solid basis for explaining lipedema-related pain. When examining lipedema-related pain reported in the pain literature, it becomes increasingly evident that dynamic mechanical allodynia, with Aß-fibers and probably tactile C (CT)-fibers, is Involved. It Is in principle possible to stimulate CT-fibers by manual lymphatic drainage (MLD), and this may explain the method's analgesic effects. Conversely however, this pain-relieving effect via CT-fibers seems to exclude the Involvement of small fiber neuropathy (SFN), and thus any direct nerve damage as the cause of pain in lipedema.

The use of velcro compression wrapping devices in the management of lymphoedema and chronic oedema is not a new concept. Wraps have been available for many years and are being used widely in clinic and community settings where bandaging or traditional compression garments are not suitable. Furthermore, they are becoming more common when treating venous disease, patients with wounds and lipoedema. The aim of this article is to introduce the reader and clinician to the new Haddenham easywrap and to demonstrate why it is different to any other velcro wrapping device available. Case studies will be utilised from clinicians currently using easywrap in clinical practice, with both therapist and patient feedback given to demonstrate the efficacy of this new velcro compression wrapping device.

Lower extremity edema is extremely common among patients seen across multiple specialties. The differential diagnosis is broad and ranges from simple dependent edema to more complex conditions such as chronic venous disease and lymphedema. Several key features from the history and physical exam can assist with the diagnosis. Imaging is rarely necessary at the initial visit unless venous thromboembolism is suspected. Treatment is specific to the etiology of the edema, but compression stockings, elevation, exercise, and weight loss remain the cornerstone in most cases.

Lymphatic vessels are lined by lymphatic endothelial cells (LECs), and are critical for health. However, the role of metabolism in lymphatic development has not yet been elucidated. Here we report that in transgenic mouse models, LEC-specific loss of CPT1A, a rate-controlling enzyme in fatty acid β-oxidation, impairs lymphatic development. LECs use fatty acid β-oxidation to proliferate and for epigenetic regulation of lymphatic marker expression during LEC differentiation. Mechanistically, the transcription factor PROX1 upregulates CPT1A expression, which increases acetyl coenzyme A production dependent on fatty acid β-oxidation. Acetyl coenzyme A is used by the histone acetyltransferase p300 to acetylate histones at lymphangiogenic genes. PROX1-p300 interaction facilitates preferential histone acetylation at PROX1-target genes. Through this metabolism-dependent mechanism, PROX1 mediates epigenetic changes that promote lymphangiogenesis. Notably, blockade of CPT1 enzymes inhibits injury-induced lymphangiogenesis, and replenishing acetyl coenzyme A by supplementing acetate rescues this process in vivo.

Lipedema an often overlooked but treatable disease Lipedema is a painful disease that affects some women between puberty and menopause through a subcutaneous fat accumulation especially in the lower extremities. Patients suffer from pain and pressure tenderness. The larger fat accumulation, especially on the inside of the thighs and knees, causes walking difficulties. This can successfully be treated by liposuction with good long-term results in terms of pain reduction and prevention of osteoarthritis development in the knee and ankle joints.
