Filter by:Lymphoedema is the swelling of one or several parts of the body owing to lymph accumulation in the extracellular space. It is often chronic, worsens if untreated, predisposes to infections and causes an important reduction in quality of life.Primary lymphoedema (PLE) is thought to result from abnormal development and/or functioning of the lymphatic system, can present in isolation or as part of a syndrome, and can be present at birth or develop later in life. Joint hypermobility ( JH) is a clinical condition characterized an excess range of motion in a joint beyond the physiological range of motion . It is termed generalized joint hypermobilty (GJH) , when the condition is asymptomatic; when it is associated with symptoms such as arthralgia, soft tissue damage, and joint instability, it is referred to as benign joint hypermobility syndrome (BJHS) .An increase in the proportion of collagen or collagen subtypes, such as type III/type I has been detected in JH . This abnormal collagen structure causes joint laxity, and fragility of the connective tissue increases. The lymphatic system begins to develop at the end of the fifth gestational week. Lymphatic vessels and lymph nodes develop from the mesoderm. Mesoderm differentiates to form many tissues and structures, including connective tissue, muscle, bone, urogenital and circulatory systems. The relationships between systems developing from the same mesoderm-derived structures (such as carpal tunnel hypermobility, lumbar disc herniation hypermobility, shoulder impigment and adhesive capsulitis hypermobility) and joint hypermobility were examined. There are studies showing that hypermobility may pose a risk for venous insufficiency. In addition, one of the criteria for benign joint hypermobility syndrome is the presence of varicose veins. It has been revealed that the lymphatic system develops embryonicly from the cardinal vein, intersomatic vein and lymphangioblasts. Therefore, the lymphatic system can be considered as a branch of the developmental venous system with endothelial vascular walls. We aimed to investigate the relationship between primary lymphedema and joint hypermobility, as it has not been investigated before in the literature and based on this developmental similarity.
This study aims to analyze the fatty tissue architecture of the subcutaneous tissue in patients from the plastic surgery department. Plastic surgery patients show a wide variety of subcutaneous fatty tissue structures during clinical examination. These include patients with edema of the extremities such as lipedema or lymphedema. Fatty tissue architecture plays a major role in our everyday lives, as wound healing and scar formation, for example, are influenced by the blood flow to the overlying skin. The fatty tissue architecture, especially in the subcutaneous fatty tissue, also plays a major role in our appearance. An analysis of the architecture can potentially provide information about the genesis of different skin fold formations. The aim of this study is to quantitatively describe structural differences in adipose tissue architecture. Adipose tissue architecture is still a largely unexplored area because imaging has not been possible to date. MSOT imaging is similar to conventional sonography in that a transducer is placed on the skin and energy is supplied to the tissue by pulsed laser light instead of sound. On a macroscopic level, this leads to a constant change of minimal oscillations of individual tissue components. The resulting sound waves can then be detected by the same transducer. Previous studies have shown that the quantitative determination of hemoglobin can be used to obtain information on blood circulation and inflammatory activity. In the extended spectrum, in contrast, not only hemoglobin and its oxygenation stages but also other biomarkers such as collagens and lipids can be detected. This is very useful for imaging of fat, lymphatics and normal and abnormal blood vessels in vascular malformations. This process was largely researched by the working group of Prof. Ntziachristos (Helmholtz Center Munich and Technical University of Munich) and Prof. Razansky (Eidgenösische Technische Hochschule Zurich) and is being further developed into a clinically applicable technology and sold commercially by the company iThera. As a first series of demonstrative clinical studies following rigorous technical development, MSOT will serve as a key tool for research partners in the investigation of several diseases that remain poorly-understood and have limited treatment options. These parallel studies will focus on lipedema and lymphedema as well as vascular malformations - three distinct disease groups with similarly unmet clinical needs for appropriate imaging modalities and high potential of translation to further major disease areas. By focusing on two unrelated diseases, this project will show the wide-reaching application of this innovative imaging approach. Following successful proof-of-principle validation in a clinical research environment, full exploitation and dissemination of the results will strive to deliver MSOT to the greater scientific community. The main objectives are to confirm/validate the spectral profile of fat and vasculature on MSOT in lipedema patients, to establish the spectral profile of vascular malformations based on MSOT for adults and children and to establish the spectral profile and imaging of lymphatic vessels. With a detailed analysis of the architecture, our understanding of the physiology and pathology of the skin may be enhanced.
The primary objective of the investigators is to develop an integrated algorithm for surgical treatment of chronic lymphedema after breast cancer surgery. This will be achieved by retrospectively analysing a subgroup of patients who had breast cancer-related surgery prior to lymphedema.
This clinical trial is designed to learn more about treating patients with lower limb lymphoedema following gynaecological surgery. The main question to be answered is To evaluate the efficacy of Daphnetin capsule in the treatment of patients with lower limb lymphedema following gynaecological malignancy surgery. Participants will take Daphnetin capsule 150mg tid (3 capsules/time, 3 times daily) orally at the same time as gradient compression stocking treatment. Researchers will compare 150mg Forte tablets (2 capsules/time, 2 times daily) and gradient compression stockings to see if Daphnetin capsule can be used to treat patients with lower extremity lymphedema following gynaecological malignancy surgery.
To examine the efficacy of complex decongestive therapy (CDT), cryotherapy and kinesio taping (KT) in patients with post-mastectomy lymphedema
Our aim in this study is to evaluate the effects of lymphedema on exercise capacity, body composition, functional level and quality of life in lymphedema patients with primary lower extremity involvement.
100 women with karyotype verified TS, previously examined at 4 study visits during a 19-year period will be asked to participate in a 5th study visit. Healthy age-matched females will be included as controls in a ratio 2:1. The aim is to examine and quantify the cardiovascular and lymphatic system in women with TS. The investigators will study a possible causal mechanism between the known pathologic phenotype and alterations in these systems to understand, prevent or treat the life-threatening complications in TS.
Breast cancer related lymphedema (BCRL) is due to its chronicity and impact an extremely dreaded complication after breast cancer treatment. The prevalence rate of objective arm and trunk/ breast BCRL is declining due to the major shift into the treatment approach of breast cancer. However, the prevalence rate of subjective arm and trunk/ breast BCRL is much higher than that of objective BCRL. Subjective BCRL is defined as the diagnosis of BCRL based on the patient's sensation of a difference in size at the arm and/or trunk without any objectively measurable swelling. At this moment, it is not clear how many breast cancer patients experience subjective arm or trunk/breast BCRL and what the underlying mechanisms may be. Therefore, the investigators hypothesize that four mechanisms might be associated with the presence and the severity of subjective arm or trunk/breast BCRL, including sensory processing problems (1. nociceptive and/or 2. neuropathic and/or 3. central) and the presence of disturbed lymphatic transport without clinical manifestation (4. subclinical BCRL). The investigators will set up a prospective longitudinal study with breast cancer patients to determine the prevalence of subjective and objective arm or trunk/ breast BCRL at 1, 6. and 12 month(s) post-surgery and the transitions between the different types of BCRL and to compare the amount of swelling at arm or trunk/ breast, the presence or severity of subclinical BCRL and peripheral and central sensory processing problems between patients with different types of BCRL. In addition, the present study will be undertaken to determine the contributing factors to the severity of subjective arm or trunk/ breast BCRL within the group of patients with subjective BCRL at different time-points after surgery (at 1, 6. and 12 month(s) post-surgery).
This study aimed to address the impact of lymphedema duration on the quality of lymphatic vessels as well as the outcome after LVA using propensity score matching.
In this observational prospective studi patients with invasive breast cancer no more than 5 cm and clinically node negative, scheduled for conservative surgery and Sentinel Node Biopsy (SNB), are enrolled in the protocol if they have 1-2 sentinel lymphnodes (SLNs) with macrometastases. SLN status will be checked on definitive sections.
