The increasing prevalence of obesity causes a major interest in white adipose tissue biology. Adipose tissue cells are surrounded by extracellular matrix proteins whose composition and remodeling is of crucial importance for cell function. The expansion ...

Microcannular liposuction in tumescent anesthesia is the most effective treatment for painful lipedema. Tumescent anesthesia is an established and safe procedure in local analgesia when performed according to guidelines. Major adverse effects are rare. In patients with advanced lipedema, however, the commonly presented comorbidities bear additional risks.We report on post-surgical acute pulmonary edema after tumescent liposuction according to guidelines in a 52-year-old female patient with lipedema of the legs. We discuss in detail possible scenarios that might be involved in such emergency. In the present case the most likely was a retarded community acquired atypical pneumonia with aggravation of pre-existent comorbidities.A combined treatment with intravenous b-lactam antibiosis, positive pressure ventilation, and continuous venovenous hemodialysis and filtration resulted in complete remission in a couple of days. In conclusion, tumescent liposuction of advanced lipedema patients should only be performed in well-trained centers with sufficient infrastructure.

Frequently misdiagnosed as obesity, lipoedema is chronic condition involving an abnormal build-up of fat cells in the legs, thighs and buttocks that cannot be shifted by exercise or dieting. Estimated to affect up to 11% of the female population, the condition is widely unknown by health professionals. This means women typically wait for many years before diagnosis. This allows the condition to progress unchecked, resulting in unnecessary deterioration and the development of associated comorbidities, as well as significant pain and mental anguish. A free, 30-minute Royal College of General Practitioners (RCGP) e-learning course created in partnership with Lipoedema UK aims to rectify this situation by educating nurses, GPs and other health professionals on how to diagnose and manage lipoedema in primary care. This article aims to describe the condition of lipoedema, how to recognise/diagnose it, current treatment options and the findings of a 240-patient survey carried out by Lipoedema UK in 2013 that included documenting the difficulties for patients in obtaining a diagnosis as well as the mental and physical effects of the condition.

Lipedema is a disfiguring disorder with abnormal and progressive deposition of adipose tissue in the hips and lower extremities almost exclusively occurring in women. There is a hereditary tendency and a substantial variability in disease severity. Lipedema is often misdiagnosed as lymphedema or morbid obesity. The etiology and pathogenesis are not understood. Early diagnosis and treatment are critical to minimize physical and psychological morbidity. The diagnosis is usually made by history and clinical examination. Non-invasive imaging techniques such as computed tomography or magnetic resonance can differentiate lipedema from other causes of edematous lower extremities. Lymphoscintigraphy may be helpful in cases which are associated with lymphedema (lipo-lymphedema). Management with manual lymphatic drainage and compression therapy are considered the most appropriate treatment. Use of conventional liposuction is controversial since it may further damage the lymphatic vessels. Newer techniques such as tumescent micro annular laser assisted liposuction and water jet-assisted liposuction have shown some promising results. Variety of other surgical procedures combined with manual lymphatic drainage and tailored post-surgical care are under investigation.

Liposuction surgically removes subcutaneous abdominal tissue (SAT) and has almost no effect on visceral abdominal tissue (VAT) depot. However, some authors suggest that deep layers of SAT are functionally similar to VAT and the amount of deep subcutaneous abdominal adipose tissue is strongly related to insulin resistance in a manner nearly identical to that of visceral adiposity. Moreover, SAT determines leptin secretion which indirectly reflects the level of insulin sensitivity in the body. Thus, the immediate removal of SAT could potentially affect metabolic profile of a patient. The current data are conflicting and cannot bring a clear evidence suggesting that liposuction itself results in important metabolic outcomes and, on the other hand, cannot exclude such a possibility. This review summarizes the liposuction-induced metabolic changes with regard to release of major adipokines and insulin sensitivity.

During the last 20 years a deeper understanding of the lymphatic circulatory system, lymph formation and composition has emerged. This review will examine the current knowledge on the organization of the lymphatic vascular tree, the formation of lymph from the extracellular fluid, lymph circulation and the lymph proteomic composition during physiological and pathological conditions. Formation of the lymph fluid is dependent on pressure gradients in the capillary beds and the composition of the endothelial cell glycocalyx, which acts as a molecular sieve. Fluid propulsion toward the draining node is dependent on the intrinsic pumping mechanism of the lymphangions and their unidirectional valves. The lymph ‘omics’ composition is dependent on the ultrafiltration of plasma proteins as well as proteins and molecules derived from the metabolic and catabolic activities of each parenchymal organ from which the lymph drains. Altogether, these new insights have brought about a new awareness of the importance of the lymphatic system in human physiology and pathology.

Methods: Thirty-six legs in 18 patients with secondary lower extremity lymphedema (LEL) and 20 legs in 10 healthy volunteers were examined using elastography. Thirty-six legs in 18 secondary LEL patients were examined using ICG lymphography. Elastography was performed on both legs at the following three sites: medial thigh (MT), medial leg (ML), and anterior ankle (AA). The area of the red region in the subcutaneous tissue demonstrated by elastography was calculated using Image software. ICG lymphography findings were classified into the following four patterns: linear (ICG1), splash (ICG2), stardust (ICG3), and diffuse (ICG4) patterns. Results: As ICG pattern progressed, the red region area was likely to increase. There was a correlation between ICG patterns and red region area according to the severity at bilateral MT (rs Z 0.665), ML (rs Z 0.623), and AA (rs Z 0.668). Significant difference was demonstrated among group means of the red region area by analysis of variance (healthy vs. ICG1 vs. ICG2 vs. ICG3 vs. ICG 4: 14.4 Æ 5.7 vs. 15.1 Æ 10.3 vs. 25.2 Æ 6.2 vs. 30.8 Æ 9.4 vs. 35.0 Æ 2.8; P < 0.001). Conclusions: The area of the red region in the subcutaneous tissue shown using elastography, which represents fluid, increases with the aggravation of lymphedema demonstrated by ICG

Background: Lipedema is a poorly known disorder of painful subcutaneous adipose tissue (SAT) likely affecting millions of women worldwide. Stage 1 lipedema has smooth skin with increased underlying fat, Stage 2 has indentations and nodules, and Stage 3 has large extrusions of skin and SAT. Women with lipedema have more SAT below the waist. As this gynoid fat is known to be cardioprotective, we aimed to determine if health declined with increasing stage and extent of lipedema SAT. Methods and Findings: Chart review from June 2012 to February 2013 at a tertiary academic center. Fifty women and one man were included in consecutive order. Fat was assessed in 29 areas for lipomas, size of the depot, and presence of lipedema fat. Pain was assessed by a numerical pain scale. Average age of patients was 50 ± 13 y; average body mass index was 38 ± 12 kg/m2. Median age of development of lipedema was 20 y. Pain occurred daily in 89.7%. None of the patients with Stage 1 lipedema had diabetes, hypertension or dyslipidemia. The amount of lipedema fat differed significantly between Stages of lipedema (p=0.003), with Stage 3 having significantly more. There was no difference in fat depot size or number of lipomas amongst Stages. Only one of 51 patients had type 2 diabetes. There was an increase in shortness of breath, palpitations, urination, and numbness in Stage 3. Conclusions: Lipedema fat can develop in any SAT location and increases in association with increasing signs and symptoms of systemic illness.

Objectives: The aim of this study was to determine the ability of the central sensitization inventory (CSI), a new screening instrument, to assist clinicians in identifying patients with central sensitivity syndromes (CSSs). Methods: Patients from a psychiatric medical practice (N = 161), which specialized in the assessment and treatment of complex pain and psychophysiological disorders, were assessed for the presence of a CSS. CSI scores, using a previously determined cutoff of “40” of “100,” were compared between the CSS patient group (n = 99) and the non-CSS patient group (n = 62). Information on false positives, false negatives, true positives, and true negatives were analyzed, and sensitivity and specificity analyses were conducted. In addition, CSS-relevant variables such as depression, abuse, and substance abuse were examined. Results: A large percentage of CSS patients had comorbid major depressive disorder (80%) and abuse history (43%), which was higher than rates for the patients without a CSS (55% and 24%, respectively). The CSI correctly identified 82.8% (n = 82) of CSS patients as having a CSS (ie, sensitivity) and 54.8% (n = 28) of non-CSS patients as not having a CSS (ie, specificity). False-positive patients (not diagnosed with a CSS, but scoring >40 on the CSI) reported more severe pain, interference in daily functioning, and abuse history, compared with the non-CSS patients who scored below 40 (ie, true negatives). Conclusions: The CSI is a useful and valid instrument for screening patients for the possibility of a CSS, although the chances of false positives are relatively high when evaluating patients with complex pain and psychophysiological disorders.

Background: Lipedema is a painful, genetically induced, abnormal deposition of subcutaneous fat in the extremities of women. The pathogenesis is unknown. Also unknown is the number of women affected in Germany. This study presents the epidemiology of the disease. There are currently two treatment options available: Complex physical decongestive therapy and liposuction. Liposuction is the only method that removes fat permanently. An additional study proves its effectiveness and highlights its vital role as part of a comprehensive treatment concept.

AIM: Application of microcurrents of bioresonance may allow protein aggregates lysis and a related enhancement of lymphatic drainage. Combining bioresonance with transcutaneous passage of active principles, by means of skin electroporation, microcirculation and clearance of connective tissues may be theoretically activated. A pilot study on an electro-medical device which includes these two technologies (Transponder(®)), has been performed on patients affected by lymphedema (LYM) and/or lipedema (LIP) of the lower limbs. METHODS: Eight patients affected by primary or secondary unilateral LYM or LIP were submitted to six consecutive daily sessions with the medical device; the first two sessions were performed by a trained physiotherapist, whilst the following four sessions were self-administered by the patients themselves at home (who were educated about the technique). Magnesium silicate was delivered transcutaneously by means of the device at each session. Pre-post-treatment assessment included: 1) limb volumetry by means of tape measurement; 2) segmental multifrequency bioimpedance spectroscopy for fluid changes, with L-DEX measurement; 3) visual analogue scale (VAS) (0-10 score) questionnaire for related symptoms. RESULTS: All the patients completed the scheduled treatment. After the treatment the mean volume of the whole limb decreased from 9462.85 (±3407.02) to 9297.37 cc (±3393.20), which accounts for a 165.48 cc (2%) reduction after six days of treatment. The pre/post-treatment VAS mean score changes were: heaviness from 4.57±3.46 to 2.43±2.57 (-47%), dysesthesias from 1.71±2.63 to 0.71±1.50 (-58%), pain from 1.57±2.57 to 0.57±0.79 (-64%). Diuresis VAS measurement passed from 7.43±1.81 to 8.57±0.98 (15% increase). The average L-DEX percentage reduction was 21%. No side effects were reported and a good patients' compliance was recorded. CONCLUSIONS: The preliminary data of this pilot study show that the combination of microcurrents of bioresonance with transdermal delivery of active principles indicate that it could result in edema decrease and symptom improvement in patients affected by LYM and/or LIP of the lower limbs. Self-administered modality of the electrical device is possible and effective; no side effects have been reported.

Juvenile dermatomyositis (JDM) is a rare but complex and potentially life-threatening autoimmune disease of childhood. Significant proportions of patients have residual weakness, muscle atrophy, joint contractures, and calcinosis. Recently, new clinical findings, such as lipodystrophy accompanied with increased fat deposition in certain areas, have been reported. So far, it is not known whether the redistribution of body fat may be the type of lipedema of lower extremity. We describe a 39-year-old woman who was diagnosed with JDM at the age of 7. Later she developed symmetrical lipodystrophy of upper extremities and symmetrical lipedema of lower extremities (making 2 and 58.3 % of total body fat mass, respectively), with multiple calcified nodules in the subcutaneous tissues. These nodules gradually increased in size despite therapy. Capillaroscopy findings showed scleroderma-like abnormalities. ANA and anti-U1RNP antibodies were positive. Similar cases with simultaneous occurrence of the lipedema of lower extremities, lipodystrophy of upper extremities, and severe calcinosis complicating JDM have not been published so far. We showed that the calcinosis and lipodystrophy were associated with short duration of active disease. Also, we display case that raises the question whether it is possible overlapping autoimmune diseases revealed during follow-up.

Upper- and lower-body fat depots exhibit opposing associations with obesity-related metabolic disease. We defined the relationship between DEXA-quantified fat depots and diabetes/cardiovascular risk factors in a healthy population-based cohort (n = 3,399). Gynoid fat mass correlated negatively with insulin resistance after total fat mass adjustment, whereas the opposite was seen for abdominal fat. Paired transcriptomic analysis of gluteal subcutaneous adipose tissue (GSAT) and abdominal subcutaneous adipose tissue (ASAT) was performed across the BMI spectrum (n = 49; 21.4-45.5 kg/m(2)). In both depots, energy-generating metabolic genes were negatively associated and inflammatory genes were positively associated with obesity. However, associations were significantly weaker in GSAT. At the systemic level, arteriovenous release of the proinflammatory cytokine interleukin-6 (n = 34) was lower from GSAT than ASAT. Isolated preadipocytes retained a depot-specific transcriptional "memory" of embryonic developmental genes and exhibited differential promoter DNA methylation of selected genes (HOTAIR, TBX5) between GSAT and ASAT. Short hairpin RNA-mediated silencing identified TBX5 as a regulator of preadipocyte proliferation and adipogenic differentiation in ASAT. In conclusion, intrinsic differences in the expression of developmental genes in regional adipocytes provide a mechanistic basis for diversity in adipose tissue (AT) function. The less inflammatory nature of lower-body AT offers insight into the opposing metabolic disease risk associations between upper- and lower-body obesity.

Lipedema is a common, but often underdiagnosed masquerading disease of obesity, which almost exclusively affects females. There are many debates regarding the diagnosis as well as the treatment strategies of the disease. The clinical diagnosis is relatively simple, however, knowledge regarding the pathomechanism is less than limited and curative therapy does not exist at all demanding an urgent need for extensive research. According to our hypothesis, lipedema is an estrogen-regulated polygenetic disease, which manifests in parallel with feminine hormonal changes and leads to vasculo- and lymphangiopathy. Inflammation of the peripheral nerves and sympathetic innervation abnormalities of the subcutaneous adipose tissue also involving estrogen may be responsible for neuropathy. Adipocyte hyperproliferation is likely to be a secondary phenomenon maintaining a vicious cycle. Herein, the relevant articles are reviewed from 1913 until now and discussed in context of the most likely mechanisms leading to the disease, which could serve as a starting point for further research.

Compression therapy is the mainstay of treatment in the management of lymphoedema and lipoedema. However, due to variance in the location, severity and type of the condition, patients often have to compromise on garments to ensure that the affected area of oedema is controlled. This article discusses the use of Veni compression shorts (Haddenham Healthcare) and Capri garments as an alternative treatment option to full-leg compression garments. The article explains treatment areas and conditions where the application of these garments will enhance care-for example, for trunkal swelling-and where compression may not generally be required-for example, in the feet.

BACKGROUND: Distinguishing lymphoedema from lipoedema in women with swollen legs can be difficult. Local tissue water content can be quantified using tissue dielectric constant (TDC) measurements. OBJECTIVES: To examine whether TDC measurements can differentiate untreated lower extremity lymphoedema from lipoedema, and to test interobserver agreement. METHODS: Thirty-nine women participated in the study; 10 patients with lipoedema (LipP), nine patients with untreated lymphoedema (U-LP), 10 patients with lymphoedema treated with compression bandaging for ≥ 4 weeks (T-LP) and 10 healthy controls. All subjects were measured at three predefined sites (foot, ankle and lower leg). All groups except U-LP were measured by three blinded investigators. Using a handheld device, a 300-MHz electromagnetic wave is transmitted into the skin via a 2.5-mm depth probe. TDC calculated from the reflected wave is directly proportional to tissue water content ranging from 1 (vacuum) to 78.5 (pure water). RESULTS: Mean ± SD TDC values for U-LP were 48.8 ± 5.2. TDC values of T-LP, LipP and controls were 34.0 ± 6.6, 29.5 ± 6.2 and 32.3 ± 5.7, respectively. U-LP had significantly higher TDC values in all measurement sites compared with all other groups (P < 0.001). A cut-off value of 40 for ankle and lower-leg measurements correctly differentiated all U-LP from LipP and controls. Intraclass correlation coefficients were 0.94 for the ankle and the lower leg and 0.63 for the foot. CONCLUSIONS: TDC values of U-LP were significantly higher than those of T-LP, LipP and controls and may aid in differentiating lymphoedema from lipoedema. Interobserver agreement was high in ankle and lower-leg measurements but low in foot measurements.
