Position paper on the management of patients with obstructive sleep apnea and hypertension: joint recommendations by the European Society of Hypertension, by the European Respiratory Society and by the members of European COST (COoperation in Scientific and Technological research) ACTION B26 on obstructive sleep apnea

This article is aimed at addressing the current state of the art in epidemiology, pathophysiology, diagnostic procedures and treatment options for appropriate management of obstructive sleep apnea (OSA) in cardiovascular (particularly hypertensive) patients, as well as for the management of cardiovascular diseases (particularly arterial hypertension) in OSA patients. The present document is the result of the work done by a panel of experts participating in the European Union COST (COoperation in Scientific and Technological research) ACTION B26 on OSA, with the endorsement of the European Respiratory Society (ERS) and the European Society of Hypertension (ESH). These recommendations are particularly aimed at reminding cardiovascular experts to consider the occurrence of sleep-related breathing disorders in patients with high blood pressure. They are at the same time aimed at reminding respiration experts to consider the occurrence of hypertension in patients with respiratory problems at night.

CCSVI and MS: a statement from the European Society of neurosonology and cerebral hemodynamics

To systematically review the ultrasonographic criteria proposed for the diagnosis of chronic cerebrospinal venous insufficiency (CCSVI). The authors analyzed the five ultrasonographic criteria, four extracranial and one intracranial, suggested for the diagnosis of CCSVI in multiple sclerosis (MS), together with the references from which these criteria were derived and the main studies that explored the physiology of cerebrospinal drainage. The proposed CCSVI criteria are questionable due to both methodological and technical errors: criteria 1 and 3 are based on a scientifically incorrect application of data obtained in a different setting; criteria 2 and 4 have never been validated before; criterion 2 is technically incorrect; criteria 3 and 5 are susceptible to so many external factors that it is difficult to state whether the data collected are pathological or a variation from the normal. It is also unclear how it was decided that two or more of these five ultrasound criteria may be used to diagnose CCSVI, since no validation of these criteria was performed by different and independent observers nor were they blindly compared with a validated gold-standard investigation. The European Society of Neurosonology and Cerebral Hemodynamics (ESNCH) has considerable concerns regarding the accuracy of the proposed criteria for CCSVI in MS. Therefore, any potentially harmful interventional treatment such as transluminal angioplasty and/or stenting should be strongly discouraged.
