Aneurysmal subarachnoid hemorrhage (SAH), in addition to the direct effects of the initial hemorrhage and secondary neurological complications, predisposes to medical complications. The proportion of deaths caused by non-neurological medical complications (cardiac, pulmonary, gastrointestinal, renal, hematological) equals that from neurological complications. In particular, pulmonary complications are responsible for 50% of all deaths from medical complications. ⋯ Moreover, amine precursor uptake and decarboxylation (APUD) cells located in the respiratory tract produce and release S100B. This protein may contribute to the pathogenesis of NPE binding RAGE receptors in alveolar epithelial type I pneumocytes and amplifying the immune and inflammatory response causing lung injury. S100B can be the link between the brain and the lung and may be among the multiple pathological pathways that determine the development of pulmonary edema after bleeding.

Plant-derived elements used for pharmacological applications constitute an increasing research field. Centella asiatica is widely used mainly as an extract (TECA). Triterpenic fractions, the primary constituents of Centella asiatica, produce a wide range of preventive and therapeutic effects. ⋯ This "status" paper - resulting from an expert meeting held in Cobham, Surrey, indicates most of the therapeutic potential of TECA, still to be explored in further studies. The status paper constitutes the basis for a consensus document on TECA to be developed in the next future. This "status" paper opens a new window on an ancient but still partially unexplored product that may become an important value in prevention and treatment of several pre-clinical and risk conditions and in clinically significant disease both as a single products and in association with other 'natural' products.

Randomized Controlled Trial
Gore external valve support for superficial saphenous vein incompetence: a 10-year, follow-up registry.
This long-term (10-year) study evaluated the safety and efficacy of expanded polytetrafluoroethylene (ePTFE) external valve support (EVS) implants used for external valvuloplasty in the treatment of incompetence of the proximal long saphenous veins. ⋯ EVS implants used to correct superficial venous incompetence at 10 years were well tolerated and produced good results on incompetence and on the evolution of varicose veins.

Randomized Controlled Trial
Topical formulation of heparin is effective in reducing the symptoms of superficial venous thrombosis: a monocenter, observer-blind, placebo-controlled randomized study.
The aim of the present, randomized, placebo controlled study was to assess the dose-dependent symptom reduction efficacy, safety and tolerability of heparin-spraygel (Viatromb 2.400 IU/g heparin spraygel) in patients with superficial vein thrombosis (SVT) of the lower limbs. ⋯ Viatromb was significantly more effective than placebo in the symptomatic treatment of SVT.

In the last years, a considerable number of studies have been performed on the relationship between infection from Helicobacter Pylori and atherosclerotic diseases, like stroke and ischemic heart disease. In particular, some infections could have a role on the genesis and development of damage to the vascular wall and of atheromatous plaque. It has been suggested that HP could influence the development of IHD through different pathways, such as endothelial cells colonization, changes in the lipid profiles, increased coagulation and platelet aggregation levels, induction of molecular mimicry mechanisms and the promotion of a low-grade systemic inflammation. ⋯ Most of this trials gave conflicting results, some denying the presence of a possible relationship between HP infection and increased risk of CAD. Despite of that, results from these studies have raised new interesting perspectives on coronary heart disease, especially regarding the possibility of modifying the clinical history of the disease through eradication of these microorganisms. The results are contradictory and require further investigation.
