Improvement of occupational leg edema and discomforts (RCT).

BACKGROUND: Edema and subjective leg complaints (e.g. pain, heaviness) after long standing or sitting, are defined as orthostatic leg complaints or occupational edema. Compression hosiery should help to prevent or decrease those symptoms. OBJECTIVE: Assess the effects on leg discomforts and leg volume and wearing comfort in two medical below-knee compression stocking types (A vs. B) with an interface pressure of 18 -20 mmHg and a below-knee-low-pressure support stocking (LPSS) with an interface pressure of 8-10mmHg (C). METHODS: Two different types of below-knee medical compression stockings and a LPSS were examined in this randomized, blinded, crossover trial in volunteers having leg discomforts and edema after being in an upright position during the day. Participants were divided into two cohorts, and each type of stocking was worn for three consecutive days in one week with a subsequent washout phase. The assessment of effects and wearing comfort was ascertained by questionnaires. Volume changes in the lower leg were measured with the Bodytronic 600® (Bauerfeind AG, Zeulenroda, Germany). RESULTS: A significant reduction of lower leg volume (mean stocking A: 204.7 ml; mean stocking B: 153.5 ml; mean stocking C: 48.2 ml) and a significant reduction of the life-quality dimension leg-complaints (p < 0.0001) was achieved by all three types of stockings. Compared to the LPSS both compression stockings decreased the lower leg volume significantly more (p < 0.001) and had a significant better fit (p < 0.001). CONCLUSION: Below-knee medical compression stockings with an interface pressure 18-21mmHg and LPSS with an interface pressure of 8-10 mmHg reduce significantly occupational orthostatic edema and leg discomforts which are due to long standing and sitting activities.

Optimisation of intermittent pneumatic compression in patients with lymphoedema of the legs

Background: Intermittent pneumatic compression (IPC) has established itself as a cornerstone in the combined decongestive therapy (CDT) of leg oedema, however, there is little evidence on the degree of volume shifts. Objectives: We performed continuous volume measurements during CDT to quantify volume shifts in a controlled trial. In addition, "wrapping/underpadding" and medical compression stockings were evaluated regarding decongestion and leg oedema, respectively. Materials & Methods: The volume reduction of CDT in patients with lymphoedema of the legs was measured. The additive decongesting effect of a padding surrounding the leg under the lymph cuff (IPC +) was evaluated. The efficacy of compression stockings in the maintenance phase was analysed. Results: Volume reductions were observed on the thigh (2%) and lower leg (5%) utilising IPC. Further significant volume reduction of the thigh (6%, p < 0.001) and lower leg (8%, p = 0.002) was observed with IPC +. Considering the thigh volume, patients with thigh-length compression stockings in the maintenance phase showed a significantly less pronounced increase in volume than patients with below-knee compression stockings (98% vs. 101% after six weeks; p < 0.05). Conclusion: The additional padding of the leg during an IPC session induces significantly more pronounced volume reduction. Medical compression stockings help to prevent volume increase in the maintenance phase.

Improvement of dynamic venous function after thermal ablation with steam vein occlusion - 6-weeks and 1-year follow-up after 167 treatments.

BACKGROUND: In this paper, the method of steam vein occlusion for the treatment of the great/small saphenous vein (GSV/SSV) was analyzed in terms of a therapeutic influence on the dynamic parameters of global vein function, its effects on subjective symptoms based on chronic venous insufficiency (CVI) and the side effects of the steam vein sclerosis (SVS). It has been questioned whether the effects of this method lead to a recommendation for routine clinical practice. METHODS: The venous drainage and the venous refilling time (T0) of the leg treated were determined by photoplethysmography (Elcat, Wolfratshausen, Germany) before, six weeks and one year after the intervention to examine the effects on global venous function. Further changes of clinical symptoms and findings were assessed by the Venous Clinical Severity Score (VCSS), preoperatively and after one year, and the complication rate at 6-week follow-up was monitored. RESULTS: The SVS was performed on 167 veins (GSV: 124; SSV: 43) in a total of 156 patients. Eight patients (5.1%) did not attend the 6-week follow-up, while 29 patients (18.6%) were lost in the 1-year follow-up. Patients were suffering from symptoms such as leg pain and leg edema, which resulted in a VCSS of 9.4 (cumulated mean score of all patients) preoperatively. The T0 was reduced to mean values of 20.6 s (GSV cohort) and 21 s (SSV cohort). The VCSS improved to 6.0 after one year. This correlated with the hemodynamic parameters. The T0 increased in the GSV cohort after six weeks to 31.8 s, p < 0.001, and showed a nonsignificant improvement to 32.2 s, p = 0.509, in the 1-year check. The T0 also increased in the SSV cohort significantly after 6 weeks to 30.1 s, p < 0.001, and showed a nonsignificant reduction after one year, p = 0.289. A total of 71%of the GSV and 69.8%of the SSV of the patients involved no complications following the treatment. Light complications (grade 1) occurred (reddening, hematoma, hyperpigmentation) in the majority: 24.2%of the GSV and 18.6%of the SSV. We noticed one grade 3 complication with thrombosis in the SSV cohort, which led to a pulmonary embolism. Forty-seven complete questionnaires were analyzed (responder rate: 28.1%); 40.4%of the patients had light complaints after the treatment, such as pain, warmth or local pressure sensations (Fig. 7); 63%of those patients noticed only slight pain at a maximum of 3 out of 10. The majority (91%) would recommend this procedure. CONCLUSION: The SVS revealed endoluminal catheter-based intervention to abolish venous reflux of the G/SSV as safe. As one therapeutic target is to eliminate venous reflux, effectiveness of a method cannot be based on sonographic data alone; one must further assess patients' symptoms and dynamic venous function. This data shows an improvement of patients' symptoms which correlated well with the improvement of the venous function in digital photoplethysmography. The SVS can be recommended as a catheter-based treatment in the future.

Influence of Medical Compression Stockings on Skin Hydration in Mainly Health Care Givers with Occupational Leg Symptoms and Edema.

BACKGROUND AND OBJECTIVE: Although compression therapy is a very effective therapy in reducing stasis-induced complaints, the wearing comfort is not always as requested. Most frequent problems are dryness of the skin and itching. This randomized, cross-over trial investigated 33 healthy participants and compared 2 different medical compression stockings: conventional stockings (type A = MCS) versus compression stockings with integrated care emulsion (type B = MCS-SkC). METHODS: Participants were divided into 2 cohorts. Both compression types were worn one after the other, 1 week each. The cohorts were named according to the sequence of the wearing periods (cohort AB/BA). PRIMARY OUTCOME: skin hydration. SECONDARY OUTCOMES: transepidermal water loss (TEWL), skin roughness, leg volume, interface pressure, and questionnaires about stasis-induced complaints and wearing comfort. RESULTS: Skin hydration: significant reduction after wearing MCS in both cohorts (p < 0.001); preservation of skin moisture after wearing MCS-SkC (p = 0.546 and p = 0.1631). TEWL: significant increase after wearing MCS (p = 0.007 and p = 0.0031); significant reduction by wearing MCS-SkC (p = 0.006 and p = 0.0005). Skin roughness: significant increase after wearing MCS (p = 0.0015 and p = 0.010), and nonsignificant decrease of skin roughness after wearing MCS-SkC (p = 0.933 and p = 0.4570). Leg volume: significantly reduced with both stockings (p = 0.004 and p = 0.0047). Regarding stasis-induced complaints, both stockings achieved good results. CONCLUSIONS: Both compression stockings are appropriate to reduce leg edema and minimize leg symptoms. MCS-SkC helps to obtain the natural skin barrier function in preserving the epidermal water content and reducing the TEWL.

The course of Kaposi's sarcoma, a marker disease for the initial diagnosis of AIDS, under ongoing cART.

While Kaposi's sarcoma (KS) was common in the 1980s and early 1990s in HIV-positive patients and one of the most common AIDS-defining diseases, its prevalence today has decreased significantly due to the early and widespread use of chimeric antigen receptor T-cell (cART) therapy. The rapid initiation of cART or, if occurring during ongoing cART, an optimization of antiretroviral therapy leads to a healing of this tumour disease in most patients. The aim of the therapy is immune reconstitution, as the immunodeficiency resulting from the HIV disease (reduced CD4+-T helper cells) promotes the development and spread of KS. This case report describes the course of KS in the first diagnosis of AIDS in a 36-year-old patient. The HIV copy count was below the detection limit and the CD3+/CD4+ T-helper cell count was only slightly below the normal value in the six-month follow-up after initial diagnosis and initiation of cART therapy. However, the clinical findings in the one-year follow-up showed only a partial response, whereby it was noted that new tumour lesions also developed focally in addition to individual progressive lesions. This was demonstrated clinically, dermatoscopically and by laser Doppler fluxmetry measurements of the lesions. Such a progression was observed in about one-third of the patients affected in various studies and is called Immune Reconstitution Inflammatory Syndrome. Other therapies in addition to cART are necessary here to suppress this immunological phenomenon (including cytostatic drugs). Promising studies are currently underway, including utilising checkpoint inhibitors. These are of great therapeutic interest due to the high immunological activity of KS itself and usually of systemic inflammatory response syndrome.

Medical compression stockings on the skin moisture in patients with chronic venous disease.

Background: Because of side effects like skin dryness and consecutive symptoms like itching the therapy of chronic venous insufficiency (CVI) with medical compression stockings (MCS) can lead to a diminished wear comfort and restricted compliance. Compression stockings with integrated skin care may have a positive influence on the skin hydration and moreover a positive effect on patients compliance. Patients and methods: In this monocentric, randomized prospective, controlled trial a below knee conventional MCS was compared to a medical compression stocking with integrated skin care (MCS-SC), interface pressure range 23-32 mmHg. Participants: 50 patients with CVI. Primary outcome: skin hydration. Secondary outcomes: transepidermal water loss, skin roughness, leg volume, interface pressure and questionnaires about quality of life and wear comfort. Results: In patients wearing MCS the skin moisture decreased (p = 0.021) and the skin roughness increased significantly (p = 0.001), whereas in patients wearing the MCS-SC skin moisture and skin roughness changed only slightly (n.s.). These protective effects of MCS-SC compared to MCS were most common in patients with CVI at stage 3 (p = 0.046), in male patients (p = 0.013) and patients with initial dry skin (p = 0.034). Both MCS reduced lower leg volume, MCS by 80 ml (p < 0.001) and MCS-SC by 60 ml (p < 0.001), both MCS improved quality of life: leg complaints (p = 0.0003); functional status (p = 0.010), well-being and life satisfaction (p = 0.030). Wear comfort: In terms of tightness, constriction in bond area and strenuous donning the MCS-SC was assessed significantly more comfortable than MCS (p < 0.001). Conclusions: MCS-SC revealed to be superior to MCS with regard to skin moisture, particularly in patients with low skin humidity, in male patients and in patients with C3, varicose veins accompanied by edema.

Advantages and disadvantages of graduated and inverse graduated compression hosiery in patients with chronic venous insufficiency and healthy volunteers: A prospective, mono-centric, blinded, open randomised, controlled and cross-over trial.

Background The therapeutic effectiveness of compression therapy depends on the selection of compression hosiery. Objectives To assess efficacy and tolerability of graduated elastic compression stockings (GECS) and inverse graduated elastic compression stockings (PECS). Methods Thirty-two healthy volunteers and thirty-two patients with chronic venous insufficiency were analysed; wear period: one week for each stocking type (randomised, blinded). PRIMARY OUTCOME: volume reduction of 'Lower leg' (Image3D®) and 'Distal leg and foot' (water plethysmography). SECONDARY OUTCOMES: clinical symptoms of chronic venous insufficiency assessed by the Venous Clinical Severity Score, side effects and wear comfort in both groups. Results Volume of 'Lower leg': significant reduction in healthy volunteers (mean GECS: -37.5 mL, mean PECS: -37.2 mL) and in patients (mean GECS: -55.6 mL, mean PECS: -41.6 mL). Volume of 'Distal lower leg and foot': significant reduction in healthy volunteers (mean GECS: -27 mL, mean PECS: -16.7 mL), significant reduction in patients by GECS (mean: -43.4 mL), but non-significant reduction by PECS (mean: -22.6 mL). Clinical symptoms of chronic venous insufficiency were improved significantly better with GECS than with PECS, p < 0.001. GECS led to more painful constrictions, p = 0.047, PECS slipped down more often, p < 0.001. Conclusion GECS and PECS reduce volume of the segment 'Lower leg' in patients and healthy volunteers. Patients' volume of the 'Distal lower leg and foot', however, were diminished significantly only by GECS ( p = 0.0001). Patients' complaints were improved by both GECS and PECS, and GECS were superior to PECS.

Compression in the treatment of chronic venous insufficiency: Efficacy depending on the length of the stocking.

BACKGROUND: Below knee two-component compression stockings (AD) have revealed as effective for compression treatment of venous leg ulcers. Upto groin, thigh length stocking (AG) may enhance clinical effects, however wear comfort of these stocking may be affected. OBJECTIVE: venous haemodynamic in relation to the length of compression stockings. METHODS: A two-component AD stocking (37 mmHg) and two thigh length stockings (AG 37, with an interface pressure of 37 mmHg; AG 45, with an interface pressure of 45 mmHg) were tested by 16 patients with CVI. Leg volume changes and venous ejection fraction and venous filling index were measured, whilst quality of life and wear comfort were surveyed by questionnaires. RESULTS: Volume of both the lower limb and the thigh was reduced by AG stockings, whereas AD stockings reduced only the volume of the lower limb and increased thigh volume. Venous hemodynamic, ejection fraction and filling index were improved by AG and AD stockings, AG, however, was superior to AD. Quality of life and comfort of the stockings was assessed as good for AG 37 mmHg, AG 45 mmHg and AD 37 mmHg. CONCLUSIONS: Thigh length two component stockings (AG) were shown to be superior to below knee stocking (AD) with regard to volume reduction and venous hemodynamic, yet wear comfort was not impaired. These results imply that healing of trophic skin changes e.g. ulcers will be faster when thigh length two component stocking will be worn.

Interface pressure and venous drainage of two compression stocking types in healthy volunteers and in patients with hemodynamic disturbances of the legs.

Standard of care in the therapy of chronic venous insufficiency (CVI) is the use of graduated elastic stockings (GECS). This paper is based on a prospective, mono-centric, open randomised, controlled and cross over study and discusses the hemodynamic effects of GECS and inverse graduated compression stockings (PECS) in 32 healthy volunteers and 32 patients with CVI and the consecutive impact on comfort. The application of stockings was performed sequentially, the allocation of the first stocking was randomized and double blind, wearing period for each stocking type about 7 days with one week of break between wearing periods. Measurements of the interface pressure were carried out by Picopress®(Microlab Elettronica, Italy) and the venous drainage were registered by strain gauge plethysmography. Mean interface pressure: GECS (level B1): 27.3 mmHg; GECS (level C): 19,6 mmHg; PECS (level B1): 17,8 mmHg; PECS (level C): 24,7 mmHg. Significant increase of EF and decrease of VFI by wearing both types of compression stockings, comparatively GESC resulted in a significantly greater improvement of EF than the PECS. PECS were significantly easier to don and put on compared to the GECS, the PECS tended to slip towards the foot more often.

Triple swabbing allows sensitive MRSA detection in dermatologic patients of a university tertiary care hospital.

BACKGROUND: To optimize preventive measures to control MRSA, we investigated retrospectively the suitability of a multiple site screening model and the optimal sampling technique to detect MRSA in a university-based phlebology and skin cancer center in Germany. PATIENTS AND METHODS: During 4.5 years samples of 3 712 inpatients in a dermatologic department were analyzed for MRSA by conventional microbiologic cultures and in parallel by PCR. Samples were taken from nares, wounds and skin lesions. RESULTS: MRSA was detected in 60 inpatients (1.6%). 268 of 7 269 (3.7%) samples at admission and during hospital stay were found positive ñ 96 (35.8%) of these were swabs of nares, 59 (22.0%) surveillance swabs, 53 (19.8%) wound swabs and 42 (15.7%) from other dermatologic lesions. Twenty-five of 60 patients (41.7%) were found positive only in the nares, 10 (16.7%) patients only in wounds and 4 (6.7%) patients only in lesions. 166 (61.9%) of all positive culture samples became positive 24 hours after cultivation, 86 (32.1%) after 48 hours, and 16 (6.0%) after 72 hours. CONCLUSIONS: Highest sensitivity to detect MRSA can be reached by combining three swabs: nares, wounds and skin lesions (ìtriple-testî). Culture of screening specimens for 72 hours is recommended.
