[Robot-assisted Lung Surgery: Techniques, Evidence and Data on Anatomical Resections].

Thanks to improved visualisation and instruments with an endowrist function, robot-assisted thoracic surgery has led to technical progress in thoracic surgery. This makes it easier to carry out complex thoracic surgical interventions, e.g.

Is Helicobacter pylori resident or transient in the human oral cavity?

Helicobacter pylori colonizes the stomachs of at least half of the world's human population. The role of the oral cavity in this colonization is not clear and there are, to date, no comprehensive data that clearly demonstrate the isolation of this bacterium from the oral cavity. The aim of this study was to evaluate the prevalence of H.

Water-filtered infrared A for the treatment of chronic venous stasis ulcers of the lower legs at home: a randomized controlled blinded study.

Background: Water-filtered infrared A (wIRA) radiation can improve the healing of acute and chronic wounds both by thermal and thermic as well as by nonthermal and nonthermic effects. wIRA increases tissue temperature, oxygen partial pressure and perfusion.

Objectives: Investigation of the influence of wIRA on chronic venous stasis ulcers in an investigator-initiated, randomized, controlled, blinded study.

Which plant for which skin disease? Part 1: Atopic dermatitis, psoriasis, acne, condyloma and herpes simplex.

Plant extracts and isolated compounds are increasingly used in cosmetics and food supplements to improve skin conditions. We first introduce the positive plant monographs with dermatological relevance of the former German Commission E. Subsequently clinical studies with botanicals for atopic dermatitis, psoriasis, acne, condylomata acuminata and herpes simplex are discussed.

The diagnosis of Sézary syndrome on peripheral blood by flow cytometry requires the use of multiple markers.

Background: Diagnosis of Sézary syndrome (SS)-defining blood involvement is hampered by the lack of Sézary cell-specific markers and nonspecific morphology of the tumour cells.

Objectives: To identify the most reliable and easy to use markers for the diagnosis of SS-defining blood involvement.

Methods: We studied 17 patients with SS and 11 control patients.

Usnea barbata extract prevents ultraviolet-B induced prostaglandin E2 synthesis and COX-2 expression in HaCaT keratinocytes.

Usnea barbata and its major constituent usnic acid are potent antimicrobial agents. Here, we have investigated anti-inflammatory properties of an U. barbata extract (UBE) containing 4% usnic acid in an ultraviolet-B (UVB) model with HaCaT keratinocytes.

Screening of plant extracts for antimicrobial activity against bacteria and yeasts with dermatological relevance.

There is cumulative resistance against antibiotics of many bacteria. Therefore, the development of new antiseptics and antimicrobial agents for the treatment of skin infections is of increasing interest. We have screened six plant extracts and isolated compounds for antimicrobial effects on bacteria and yeasts with dermatological relevance.

Cerebral vasomotor reactivity is significantly reduced in low-flow as compared to thromboembolic infarctions: the key role of the circle of Willis.

To test the hypothesis that cerebral vasomotor reactivity (CVMR) is significantly more reduced in patients with hemispheric low-flow infarctions than in brain infarctions due to arterio-arterial embolism, a series of 64 consecutive patients with internal carotid artery occlusions were studied. CVMR was calculated from relative changes of blood flow velocity within the middle cerebral artery (MCA) measured by transcranial Doppler ultrasonography (TCD) during hypo- and hypercapnia. The configuration of the circle of Willis (COW) was also determined by TCD using common carotid artery compression tests.
