Abstract
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). Four hundred patients suffering from GSV incompetence were assigned to EVLA or HLS of the GSV. One hundred and eighty five and 161 patients (=limbs), respectively, were treated per protocol. Main outcome measures were clinically recurrent varicose veins after surgery (REVAS classification, primary study objective), Duplex detected saphenofemoral recurrence, clinical venous severity scoring (Homburg Varicose Vein Severity Score), quality of life (Chronic Venous Insufficiency Questionnaire 2), side effects, and patient satisfaction 5 years after treatment. RESULTS Two hundred and eighty one legs (81% of the study population) were evaluated with a median follow up of 60.4 (EVLA) and 60.7 months (HLS). Overall, REVAS was similarly observed in both groups: 45% (EVLA) and 54% (HLS), p = .152. Patients of the EVLA group showed significantly more clinical recurrences in the operated region (REVAS: same site): 18% vs. 5%, p = .002. In contrast, more different site recurrences were observed in the HLS group: 50% vs. 31%, p = .002. Duplex detected saphenofemoral refluxes occurred more frequently after EVLA: 28% vs. 5%, p < .001. Both treatments improved disease severity and quality of life without any difference. CONCLUSIONS EVLA and HLS are comparably effective concerning overall REVAS, improvement of disease severity, and quality of life. In terms of same site clinical recurrence and saphenofemoral refluxes, HLS is superior to EVLA 5 years after treatment. CLINICAL TRIAL REGISTRATION ISRCTN18322872.

Abstract
A spectroelectrochemical cell has been designed to combine electrochemistry and ultrafast two-dimensional infrared (2D-IR) spectroscopy, which is a powerful tool to extract structure and dynamics information on the femtosecond to picosecond time scale. Our design is based on a gold mirror with the dual role of performing electrochemistry and reflecting IR light. To provide the high optical surface quality required for laser spectroscopy, the gold surface is made by electron beam evaporation on a glass substrate. Electrochemical cycling facilitates in situ collection of ultrafast dynamics of redox-active molecules by means of 2D-IR. The IR beams are operated in reflection mode so that they travel twice through the sample, i.e., the signal size is doubled. This methodology is optimal for small sample volumes and successfully tested with the ferricyanide/ferrocyanide redox system of which the corresponding electrochemically induced 2D-IR difference spectrum is reported.

Abstract
Resection margins of melanomas in the head and neck region often have to be adapted according anatomical circumstances. In the case of thicker primary tumors or after complete resection of locoregional lymph node metastases, adjuvant therapy with interferon-α can be performed; in some cases, adjuvant radiotherapy may also be indicated. In the case of inoperable lymph node or distant metastases, systemic treatment is required. Beside well-established mono- or polychemotherapy regimens, newer targeted therapies with BRAF inhibitors (vemurafenib, dabrafenib), mitogenic-activated protein kinase (MEK) inhibitors (trametinib, binimetinib, and cobimetinib), and kinase inhibitors (imatinib, sunitinib, nilotinib, dasatinib) are also available.

Abstract
Encoding muscular force output during voluntary contractions is widely perceived to result, at least in part, from modulations in neuronal activity within the sensorimotor cortex. However the underlying electrophysiological phenomena associated with increased force output remains unclear. This study directly assessed sensorimotor cortex activity using electroencephalography (EEG) in humans performing isometric knee-extensions at a range of discrete torque levels. Fifteen healthy males (age 24 (s=5) years) completed one familiarization and one experimental trial. Participants performed a cyclic series of 60 isometric knee-extension contractions with the right leg, including 15 contractions of a 5-s duration at each of four discrete torque levels: 15%, 30%, 45% and 60% of maximal voluntary torque (MVT). Isometric knee-extension torque, quadriceps electromyography and EEG were recorded at rest and throughout all the contractions. EEG (0.5-50 Hz) was collected using a 32-channel active-electrode cap. A voxel-based low-resolution brain electromagnetic tomography (LORETA) analysis calculated cortical activation within the sensorimotor cortex (one of 27 MNI coordinates) for the entire 0.5-50-Hz range (cortical current density (CCD)), as well as for each constituent frequency band in this range (delta, theta, alpha, beta and gamma). Gamma band (30-50 Hz) cortical activity increased with contraction torque (analysis of variance [ANOVA], P=0.03). Conversely, activity within the other frequency bands was not modulated by torque (P≥0.09), nor was overall CCD (P=0.11). Peripheral neuromuscular activation (quadriceps electromyography (EMG) amplitude) demonstrated distinct increases between each torque level (P<0.01). In conclusion, sensorimotor cortical activity within the gamma band demonstrated an overall increase with contraction torque, whereas both CCD and each of the other constituent frequency bands were not modulated by increments in torque magnitude during isometric knee-extension contractions up to 60%MVT.

Abstract
BACKGROUND Phlebologic diseases have become extremely common and have major socio-economic impact. However, the percentage of dermatologists working in phlebology appears to be decreasing according to the data of the German Society of Phlebology (DGP). METHODS To investigate the reasons for this development, we--on behalf of the DGP--sent a questionnaire to 120 German Departments of Dermatology in autumn 2012. RESULTS In 76 returned questionnaires, the number of physicians with additional fellowship training in phlebology averaged 1.5; the average number of those who fulfill the criteria for training fellows in phlebology was 0.9. In 71.1 % of the departments there was a phlebologist. A special phlebologic outpatient clinic existed in 73.7 % of the departments. Sonography with Doppler (89.5 %) and duplex (86.8 %) was used as the most frequent diagnostic tool. For therapy, compression (94.7 %), sclerotherapy (liquid 78.9 %, foam 63.2 %, catheter 18.4 %), endoluminal thermic procedures (radio wave 28.9 %, laser 17.1 %) and surgery (especially crossectomy and stripping 67.1 %, phlebectomy of tributaries 75 %) were used. The average number of treatments was very heterogenous in the different departments. CONCLUSIONS Phlebology definitely plays an important role in dermatology. Most departments fulfill the formal criteria for the license to conduct advanced training in phlebology. A wide spectrum of phlebological diagnostic and therapeutic procedures is available.

Abstract
A five-day-old female infant presented with congenital red-livid papules and nodules on the head, chest, back and left arm. The nodule on the chest was ulcerated at birth. The pregnancy and delivery were uneventful. There was no history of birth trauma to account for the ulcerated lesion. The parents and the three older siblings were healthy without similar skin lesions. The skin biopsy showed in the deep layer of the dermis a multinodular, granulomatous histiocytic infiltrate. The histiocytic cells expressed S-100 and CD1a. There were additionally many eosinophils. The suspected diagnosis Langerhans cell histiocytosis was confirmed by the histologic results. The patient was referred to pediatric hematology-oncology where evaluation showed no evidence of systemic involvement. The clinical, radiological, sonographic and histological results led to the diagnosis of a congenital, monosystemic, oligolesional Langerhans cell histiocytosis of the skin. In addition to the case presentation, we review the current stand of knowledge of the pathogenesis, the clinical classification and the therapy of the Langerhans cell histiocytosis.

Abstract
The diagnosis of scabies is clinically not always simple without the detection of mites. Histology can be difficult, particularly without clinico-pathologic correlation. [corrected] Even after adequate antiscabies treatment the dermatological symptoms and complaints can persist and necessitate an [corrected] intensive follow-up treatment. The case example described here underlines that in consideration of the multifaceted clinical appearance and the sometimes difficult detection of mites, scabies should always be considered as a differential diagnosis in cases of persistent pruritis.
