Sclerotherapy of lower limb veins: Indications, contraindications and treatment strategies to prevent complications - A consensus document of the International Union of Phlebology-2023.

Background: Sclerotherapy is a non-invasive procedure commonly used to treat superficial venous disease, vascular malformations and other ectatic vascular lesions. While extremely rare, sclerotherapy may be complicated by serious adverse events.

Objectives: To categorise contraindications to sclerotherapy based on the available scientific evidence.

Clinical Perspectives and Management of Edema in Chronic Venous Disease-What about Ruscus?

Edema is highly prevalent in patients with cardiovascular disease and is associated with various underlying pathologic conditions, making it challenging for physicians to diagnose and manage. We report on presentations from a virtual symposium at the Annual Meeting of the European Venous Forum (25 June 2021), which examined edema classification within clinical practice, provided guidance on making differential diagnoses and reviewed evidence for the use of the treatment combination of extract, hesperidin methyl chalcone and vitamin C. The understanding of the pathophysiologic mechanisms underlying fluid build-up in chronic venous disease (CVD) is limited.

CEAP clinical classes C0S-C4: differences, similarities and role of Ruscus + HMC + vitamin C in patients with chronic venous disease.

Since the publication of the CEAP classification, new research has enriched our knowledge; notably on the heritability of CVD and the genetic and environmental factors involved in this condition, as well as the symptoms apparent within the spectrum of the CEAP clinical classes and the benefits of medical treatment. Using the CEAP classification as a special theme, a symposium with the same title as the present paper was held at the annual meeting of the 2019 European Venous Forum. The lectures presented much valuable information, from which some key points can be extracted.

The driving mechanisms of the carbon cycle perturbations in the late Pliensbachian (Early Jurassic).

The Early Jurassic (late Pliensbachian to early Toarcian) was a period marked by extinctions, climate fluctuations, and oceanic anoxia. Although the causes of the early Toarcian Oceanic Anoxia Event (OAE) have been fairly well studied, the events that lead to the Toarcian OAE, i.e.
