Asymptomatic DVT and fibrin sheaths do not represent per se an indication for removal of functioning CVC in cancer patients who need central vein access.

Our results show that amyloidosis and systemic hypertension produce both LV twist and untwist rate enhancement before LV hypertrophy is developed. In patients with amyloidosis irrespectively of LV infiltration degree, a significant LV untwisting rate peak delay occurs suggesting that different aetiology of cardiac involvement could differently affect LV untwisting rate.

EpidemiologyHeadaches are the most prevalent neurological disorders and are among the most frequent symptoms seen in general practice. The headache is about 30% of neurological specialist visits and continues to be a frequent cause of ED use, accounting for 2% of all visits. 4 50% of the general population have headaches during any given year, and more than 90% of them report a lifetime history of headache. 5 The only Italian epidemiological study (PACE study) 6 showed that 52% of men a and 43% of women interviewed suffered from headache in the last year. 7 Primary headache Migraine IntroductionMigraine is a common, debilitating headache disor- ABSTRACTHeadaches are the most prevalent neurological disorders and continue to be a frequent cause of Emergency Department use, accounting for 2% of all visits.

The keys to effective management of these syndromes are differential diagnosis through history, physical examination, and diagnostic studies when necessary. This monograph highlights the importance of establishing whether headache is a secondary symptom of another disease process or a primary condition. The goal of headache management is for patients and healthcare professionals to work together to minimize pain and improve quality of life.

The Authors report an accidental gas exposure of Chlorine gas in a worker. This accident is very uncommon and can lead to important life-threatening conditions, such as Reactive Airway Disfunction Syndrome (RADS) and Acute Respiratory Distress Syndrome (ARDS) with important pulmonary disfunctions and even death. This syndrome results are reversible when a quick and appropriate intensive treatment is performed.
