    Abstract Background/Purpose: Leukemia cutis (LC), by definition, is the infiltration of neoplastic leukocytes in the skin. The overall incidence of LC is rare. We aimed to investigate the association between clinical characteristics, classifications and prognosis among different types of LC in Taiwan. Methods: We performed a retrospective analysis of forty-two patients with histopathology proven LC based on skin biopsies in a medical center in Southern Taiwan from 1997 to 2018. The study involved medical records of the patients, clinical manifestations, and outcomes according to different types of leukemia. Results: This series consisted of 27 males and 15 females, and the mean age was 55.7 years old. The most common cutaneous features were papules (38%) and nodules (29%), followed by plaques (16%) and ulcers (10%). The most commonly affected sites were the trunk (33%) and extremities (31.5%), although generalized distribution (14%) was not rare. The prognosis of LC was very poor, 76.2% of patients (32/42) died during the follow-up, and the median survival time was 7.2 months (95% CI, 4.53–9.87 months). No statistical significance was found (P = 0.068 for survival curves) among different types of LC. Conclusion: This study was the first large-scale research in regarding to LC of Han Chinese. The commonest clinical presentations were papules and nodules, and the predilection sites were trunk and extremities. Besides, there was the high frequency of LC from AML and MDS in Taiwan. Clinicians should pay more attention to the leukemia patients with extramedullary manifestations due to poor survival outcomes.

    Abstract Background: Subjects exposed to occupational standing are at risk of developing chronic venous disease. Graduated compression stockings (GCS) counteract venous hypertension. Aim of the present investigation was to assess GCS clinical and cost effectiveness in prolonged standing up workers.
    Methods: Randomized controlled trial involving 75 healthy healthcare professionals working in 6 hours standing up shifts without or with GCS (group A and B, respectively). Outcome measures were performed before and after the shift, at baseline (T0), at 1 (T1), 6 (T6) and 12 (T12) months and included lower limb volume, air plethysmography (APG), quality of life, and dedicated cost-effectiveness questionnaires.
    Results: Seventy-two subjects completed the data collection. Leg volume increased in group A and decreased in B at all assessment points (T0, 1, 6, 12) (P<0.0001). Venous filling index did not change within the 12 months, but, after every shift, its value was lower in B compared to A (P<0.0001). At 12 months, VVSymQ worsened in A and improved in B (P<0.0001) and CIVIQ significantly worsened in A (P<0.0001), while in B it significantly improved (P<0.0001). Perceived disability was higher in A at 12 months (P<0.001) and the cost calculation revealed a saving of 1510 euro per year in B.
    Conclusions: GCS counteracted occupational oedema and positively influenced venous filling index, while improving vein specific quality of life measurements in addition to cost savings.

    Abstract Objective: The aim of this study was to compare the outcomes and complications of selected patients treated with endovenous laser ablation (EVLA) or ambulatory phlebectomy for foot varicose veins.
    Methods: From October 2016 to February 2022, selected patients undergoing EVLA (using 1470-nm with radial-slim or bare-tip fibers) or phlebectomy of foot varicose veins for cosmetic indications were analyzed, and the outcomes were compared. Patients were classified according to the Clinical, Etiologic, Anatomical, and Pathophysiological (CEAP) classification. Anatomic criteria provided the basis for the decision to perform EVLA or phlebectomy. Clinical and ultrasound assessments were performed on postoperative days 7, 30, and 90 for visualization of the sapheno-femoral and sapheno-popliteal junctions and the deep venous system. Disease severity was graded with the Venous Clinical Severity Score (VCSS), and quality of life was measured with the Aberdeen Varicose Vein Questionnaire (AVVQ) before and after treatment. Treatment outcomes were evaluated based on changes in VCSS and AVVQ scores. The groups were also compared for procedure-related complications. Data were statistically analyzed in SPSS v. 20.0 using the χ
    Results: The study included 270 feet of 171 patients. Mean patient age was 52.3 (standard deviation, 13.1) years, ranging from 21 to 84 years; 133 (77.8%) were women. Of 270 feet, 113 (41.9%) were treated with EVLA and 157 (58.1%) with phlebectomy. The median preoperative CEAP class was 2 (interquartile range, 2-3) in the phlebectomy and EVLA groups, with no statistically significant difference between the groups (P = .507). Dysesthesia was the most common complication in both groups. Only transient induration was significantly different between EVLA (7.1%) and phlebectomy (0.0%) (P = .001). The two approaches had an equal impact on quality of life and disease severity.
    Conclusions: Treatment complications were similar in phlebectomy and EVLA and to those previously described in the literature.

    Abstract Background: Sclerotherapy is among the mainstays of chronic venous disease treatment, yet its occlusion rate remains suboptimal compared to thermal tumescent techniques. An innovative three-balloons catheter has been developed to allow sclerotherapy in empty vein conditions (empty vein ablation technique, EVA). Aim of this investigation was to describe the EVA technical aspects and related ex-vivo effects on vein wall.
    Methods: Two samples from jugular veins of an adult sheep were treated by EVA or foam sclerotherapy (FS, Tessari method). Primary outcome was the percentage of circumferential intima treated by EVA or FS; secondary outcomes were intima and media thickness modifications after treatment.
    Results: Intact circumferential residual intima were 6.07±2.94% and 16.55±0.70% after EVA and FS, respectively (P=0.020). Despite the average intima and media thickness did not differ between treatments, EVA demonstrated a homogenous damage throughout the vein segment, while FS effect was less destructive distally to the injection site, because moving away from the injection site and floating, it has a less contact with internal surface of the vein.
    Conclusions: EVA seems to overcome chemical ablation limits as flushing effect and the increases vein wall/sclerosant agent contact effect compared to FS. Ex-vivo encouraging results need in-vivo validation to evaluate other points like deactivation of sclerosing agent by blood protein and the contact time control between SA and the vein wall. If we have further confirmations in vivo we might think we have a potential higher occlusion rate compared to FS, paving the way for future clinical trials.

    Abstract Background: Sclerotherapy is a cornerstone of the treatment of chronic venous disease, despite some technical aspects (e.g., sclerosant liquid agent concentration [SLAC] and contact time between sclerosant agent and vein wall [ctSA/VW]) to maximize outcomes remain an unsolved problem and a source of debate. An innovative three-balloon catheter has been developed to allow sclerotherapy in empty vein conditions (Empty Vein Ablation technique, EVA), revolutionizing the definition of SLAC and ctSA/VW. Aim of this experimental study is to analyze EVA effects on intima and media vessel tunicae using different SLAC and ctSA/VW in an in-vivo animal model.
    Methods: Two adult sheep were treated by EVA using jugular and common iliac vein axes (eight vein segments). Different SLAC (polidocanol 0.5% or 1%) and different ctSA/VW (3 or 5 minutes) were combined for testing residual circumferential intima percentage and media thickness after EVA.
    Results: Intact circumferential residual intima after the treatment was 21.3±4.9%, 18.2±7.4%, 15.7±2.4% and 8.9±2.0% using 0.5% (3 min), 0.5% (5 min), 1% (3 min) and 1% (5 min), respectively (R
    Conclusions: EVA proved to be effective in venous wall destruction even with a very low SLAC and ctSA/VW (0.5% in 3 minutes), in quite large caliber veins. Direct comparisons with foam/liquid sclerotherapy should be done to confirm therapeutic effectiveness of these results, despite EVA has provided a maximized and controlled SA/VW contact time and ratio.

    Abstract Objective: Venous Thromboembolism (VTE) is a commonly underdiagnosed disease with severe consequences and an exceedingly high mortality rate. Conventional compression wraps are devised for therapeutic purpose but lack diagnostic capacity. Recent advances in flexible electronics and wearable technologies offer many possibilities for chronic disease management. In particular, vital signs have been studied to show a strong correlation with the risk of VTE patients. In this study, we aim to develop an intelligent theranostic compression device, referred to as iWRAP, with the built-in capacity of real-time vital sign monitoring together with auto-adjustable compression level.
    Methods: An instantaneous pneumatic feedback control with a high-resolution pressure sensor is integrated to provide a highly stabilized compression level at the prescribed interface pressure for an improved therapeutic outcome. Meanwhile, arterial pulse waveforms extracted from the pressure readings from the smart compression device can be utilized to derive the body vital signs, including heart rate (HR), respiratory rate (RR) and blood pressure (BP).
    Results: A reliable delivery of the targeted compression level within ±5% accuracy in the range of 20-60 mmHg has been achieved through the feedback of the interface pressure. Both HR and RR have been measured within clinical-grade accuracies. Moreover, BP estimated using an ALA model has been achieved at low compression levels, which is also within a clinical-acceptable accuracy. The acquired vital information has been instantaneously fit into the clinically acceptable criteria for life-threatening PE risk with timely assessments.
    Conclusion: The iWRAP has shown the potential to become the first theranostic wearable device with both continuous delivery of accurate and effective compression therapy and real-time monitoring of life-threatening conditions for VTE patients.

    Abstract Here we describe a combination of neodymium:yttrium-aluminium-garnet 1064-nm laser emission and injection of 75% dextrose solution to treat lower limb reticular veins. The strategy is known as cryo-laser cryo-sclerotherapy. Preliminary outcomes are reported, showing ecchymosis in up to 30% of cases and intravenous thrombus in 14%. A satisfactory vessel elimination is found in 86% of cases. No improvement or worsening was reported in 14% of patients. The paper provides technical details with the aim of promoting homogeneity in future data collection, so fostering publication of long-term effectiveness and related comparative evaluation with sclerotherapy and laser treatment alone.
