Comparison of endovascular strategy versus hybrid procedure in treatment of chronic venous obstructions involving the confluence of common femoral vein.

Objective: Treatment of extensive chronic venous obstruction (CVO) with post-thrombotic trabeculation involving the common femoral vein with extension into the femoral vein or deep femoral vein remains a challenge and the best treatment technique for such cases is not clear. In the present study, we compared the results of endovascular alone vs endovascular with additional endophlebectomy (hybrid) procedures for such patients.

Methods: The medical records of 102 consecutive patients (108 limbs) treated between 2015 and 2020 for iliofemoral CVO extending to the femoral confluence were retrospectively reviewed.

Intermittent pneumatic compression after varicose vein surgery.

Objective: Intermittent pneumatic compression (IPC) is an established treatment option to remove tissue fluid from patients with lymphedema and chronic venous disease. The effects of IPC applied directly after varicose vein surgery performed with high volumes of tumescent local anesthesia have not been investigated. The aim of the present study was to evaluate the use of postoperative IPC concerning its effects on the leg volume and patient comfort after surgery.

Short-Term Efficacy of Inguinal Reoperation for Recurrent Saphenofemoral Incompetence using the Stump Suture Technique.

Objectives: Neovascularization from the saphenofemoral junction (SFJ) is regarded to be an important cause of clinical recurrence. The ideal treatment of SFJ recurrence is still a matter of debate. Barrier strategies have been implemented to improve surgical outcome by reducing neovascularization.

Chemosensitivity-directed therapy compared to dacarbazine in chemo-naive advanced metastatic melanoma: a multicenter randomized phase-3 DeCOG trial.

Chemotherapy still plays an important role in metastatic melanoma, particularly for patients who are not suitable or have no access to highly efficacious new therapies. Pre-therapeutic chemosensitivity testing might be useful to identify optimal chemotherapy regimens for individual patients. This multicenter randomized phase-3 trial was aimed to test for superiority of chemosensitivity-directed combination chemotherapy compared to standard dacarbazine monochemotherapy, and to demonstrate the chemosensitivity test result as prognostic in metastatic melanoma.

Same Site Recurrence is More Frequent After Endovenous Laser Ablation Compared with High Ligation and Stripping of the Great Saphenous Vein: 5 year Results of a Randomized Clinical Trial (RELACS Study).

Objective: To compare the long-term clinical efficacy of endovenous laser ablation (EVLA) with high ligation and stripping (HLS) as standard treatment for great saphenous vein (GSV) incompetence.

Design: Investigator initiated two centre randomized controlled trial with 5 year follow up.

Materials And Methods: Interventions were performed on ambulatory and hospitalized patients at two vein centres, a university dermatology department (EVLA) and a specialized vein clinic (HLS).

Ultraviolet damage, DNA repair and vitamin D in nonmelanoma skin cancer and in malignant melanoma: an update.

Skin exposure with UV radiation (UV) is the main cause of skin cancer development. Epidemiological data indicate that excessive or cumulative UV exposure takes place years and decades before the resulting malignancies arise. The most important defense mechanisms that protect human skin against UV radiation involve melanin synthesis and active repair mechanisms.

Graft-versus-host disease or toxic epidermal necrolysis: diagnostic dilemma after liver transplantation.

Graft-versus-host disease (GvHD) and toxic epidermal necrolysis (TEN) are rare and severe complications after liver transplantation. While mild acute GvHD is quite different from TEN and easy to distinguish, severe acute GvHD and TEN can be hard to differentiate because of similar clinical symptoms. We herein report a case with rapid progression of critical illness, after liver transplantation, caused by GvHD or TEN, although between those, diagnosis was not possible during the clinical course.

Reciprocal responses of fibroblasts and melanocytes to α-MSH depending on MC1R polymorphisms.

The melanocortin 1-receptor (MC1R) exhibits several variants in form of single nucleotide polymorphisms (SNPs) that are known to differentially regulate melanocyte function. However, whether and how MC1R polymorphisms also affect fibroblast function has not been investigated so far.Therefore we measured intracellular cyclic adenosine monophosphate (cAMP) concentrations and cellular proliferation upon stimulation with alpha-melanocyte stimulating hormone (α-MSH) in eight different human fibroblast and melanocyte cell lines with wild type and different MC1R SNPs.

Comparable effectiveness of endovenous laser ablation and high ligation with stripping of the great saphenous vein: two-year results of a randomized clinical trial (RELACS study).

Objective: To compare the clinical efficacy and safety of endovenous laser treatment (EVLT) with high ligation and stripping (HLS) as standard treatment for great saphenous vein (GSV) insufficiency.

Design: Two-center randomized controlled trial with 2-year follow-up.

Setting: Interventions were performed on ambulatory and hospitalized patients at 2 vein centers, a university dermatology department (EVLT-treated group), and a specialized vein clinic (HLS-treated group).

Radiofrequency induced thermotherapy (RFITT) of varicose veins compared to endovenous laser treatment (EVLT): a non-randomized prospective study concentrating on occlusion rates, side-effects and clinical outcome.

Background: Radiofrequency obliteration (RFO) and endovenous laser treatment (EVLT) are established techniques in varicose therapy. A novel bipolar RFO technique - Radiofrequency Induced Thermotherapy (RFITT) - was introduced in 2007. Comparative studies of RFITT and EVLT with one year follow-up are missing.

Construction and evaluation of a multidimensional score to assess varicose vein severity - the Homburg Varicose Vein Severity Score (HVVSS).

To evaluate a novel score (HVVSS) for varicose vein patients combining subjective symptoms, clinical findings and functional data of venous insufficiency. 91 patients (118 legs) with primary varicose veins of the great, small or accessory anterior saphenous vein were treated with conventional surgery. HVVSS was assessed pre- and 3 months postoperatively.

Number of metastases, serum lactate dehydrogenase level, and type of treatment are prognostic factors in patients with brain metastases of malignant melanoma.

Background: This multicenter study aimed to identify prognostic factors in patients with brain metastases from malignant melanoma (BM-MM).

Methods: In a retrospective survey in 9 cancer centers of the German Cancer Society, 692 patients were identified with BM-MM during the period 1986 through 2007. Overall survival was analyzed using a Kaplan-Meier estimator and compared with log-rank analysis.

Sorafenib and pegylated interferon-α2b in advanced metastatic melanoma: a multicenter phase II DeCOG trial.

Background: The combination of sorafenib, a multikinase inhibitor, and pegylated interferon-α2b (Peg-IFN-α2b) could potentially lead to an improved antitumoral response. Previously, combinations of interferon and sorafenib have been used in renal cell cancer.

Patients And Methods: Patients with stage IV metastatic melanoma and no previous systemic therapies apart from adjuvant immunotherapy received Peg-IFN-α2b 3 μg/kg once per week, and sorafenib 400-mg b.

Venoarterial flow index steadily improves after endovenous laser treatment of the great saphenous vein.

Background: Endovenous laser treatment (EVLT) is a minimally invasive procedure to ablate varicose veins. The venous arterial flow index (VAFI) represents a quantitative duplex ultrasound parameter to characterize venous hemodynamics, which has not been investigated in EVLT so far.

Objective: To analyze the hemodynamic improvement of EVLT of the great saphenous vein (GSV) according to VAFI measurement.

MGMT gene promoter methylation correlates with tolerance of temozolomide treatment in melanoma but not with clinical outcome.

Background: Despite limited clinical efficacy, treatment with dacarbazine or temozolomide (TMZ) remains the standard therapy for metastatic melanoma. In glioblastoma, promoter methylation of the counteracting DNA repair enzyme O(6)-methylguanine-DNA-methyltransferase (MGMT) correlates with survival of patients exposed to TMZ in combination with radiotherapy. For melanoma, data are limited and controversial.

High-throughput miRNA profiling of human melanoma blood samples.

Background: MicroRNA (miRNA) signatures are not only found in cancer tissue but also in blood of cancer patients. Specifically, miRNA detection in blood offers the prospect of a non-invasive analysis tool.

Methods: Using a microarray based approach we screened almost 900 human miRNAs to detect miRNAs that are deregulated in their expression in blood cells of melanoma patients.

Efficacy of low-dose interferon {alpha}2a 18 versus 60 months of treatment in patients with primary melanoma of >= 1.5 mm tumor thickness: results of a randomized phase III DeCOG trial.

PURPOSE Low-dose (LD) interferon (IFN) alfa (LDI) has demonstrated a consistent disease-free survival benefit for patients with clinically lymph node-negative melanoma in clinical trials. However, the optimal duration of treatment is still under discussion, and no previous trial has evaluated this question specifically. A prolongation of LDI from 18 months to 60 months might be of clinical benefit for patients with intermediate or high-risk melanoma.
