The records of 293 patients admitted to Padua University Eye Clinic with diagnosis of optic neuropathy were reviewed. Age and sex distribution of different types of optic neuropathies were analyzed. 84 patients (28.7%) with a mean age of 61.9 years had anterior ischemic optic neuropathy (AION). The mean follow up of these patients was 3 years. In less than 30% of patients stabilized visual acuity of the first affected eye was better than 20/200; however, patients younger than 65 showed a significantly (p less than 0.01) better visual acuity than patients older than 64. Involvement of the second eye was found in 26 patients with AION (30.9%), of whom only five were considered idiopathic. The latency before controlateral eye involvement was significantly (p less than 0.05) shorter in patients over 64 years of age than in the younger group. Commonly known associated conditions such as giant cell arteritis (3.6%), arterial hypertension (34.5%), diabetes mellitus (10.7%), both arterial hypertension and diabetes (8.3%), migraine (7.2%) or intracapsular cataract extraction (1.2%) were considered. The frequency of a number of risk factors was found out in patients with arterial hypertension and/or diabetes and in patients with idiopathic AION. Symptoms or signs of ischemic cardiopathy and/or peripheral nonarteritic vascular disease, TIAs prior to AION onset, elevated plasma cholesterol or triglyceride levels, excessive smoking were considered. These risk factors were not found in 11.1% of diabetic patients with AION, in 37.9% of hypertensives, in 14.2% of both diabetic and hypertensive patients and in 31% of patients with idiopathic AION. Our data seem to indicate that the onset of AION may be influenced more strongly from these risk factors than aging.

In the population of the city of Tampere, Finland, 66 patients with histologically verified temporal arteritis were identified during the 20-year period from 1969 to 89. The cases were followed up to March 31st in 1991. The annual age- and sex-adjusted incidence of temporal arteritis per 100,000 population aged 50 or older was 4.5 in 1970-79 and 9.2 in 1980-89. The patients showed excess mortality although this was not statistically significant. After excluding hypertensive disease, angina pectoris and congestive heart disease the survival of the remaining subgroup did not differ from the control population.

Pulmonary artery aneurysm in adults is a rare diagnosis. Most cases described in the literature are either associated with congenital heart disease or pulmonal arterial hypertension, respectively, or are not true aneurysms but rather pseudoaneurysms, which are usually iatrogenic. We present the case of a 68-year old female patient with the incidental finding of a true aneurysm of the right peripheral pulmonary artery with a maximum diameter of 4 cm. With increasing aneurysm diameter over time, the decision for a surgical resection was made. Complete resection of the aneurysm including lower lobe resection was performed. Histopathological examination showed necrotizing giant cell arteritis as the underlying cause. The postoperative course was uneventful and no signs of further disease activity were detected. To our knowledge, this is the first reported case of a pulmonary artery aneurysm caused by giant cell arteritis, whereas it should be noted that the distinction between Takayasu arteritis and giant cell arteritis is not clearly defined. Considering the high mortality associated with aneurysm rupture, surveillance is advocated for small aneurysms, whereas for larger aneurysms and those showing signs of progression in size despite medical therapy or even dissection, surgical intervention should be considered.

Polymyalgia rheumatica (PMR) represents the most common inflammatory rheumatic disease of the elderly. It is characterized by synovitis of proximal joints and extra-articular synovial structures, along with chronic high-grade systemic inflammation. PMR is closely related to giant cell arteritis (GCA), a large-vessel vasculitis that involves the major branches of the aorta, particularly the extracranial branches of carotid artery including temporal arteries. It is currently believed that PMR and GCA may represent different manifestations of the same disease process. Chronic systemic inflammation is presently recognized as one of the key pathogenic mechanisms underlying cardiovascular disease and associated complications, including cardiac arrhythmias and sudden death. In this regard, several studies demonstrated that besides promoting structural heart disease, inflammatory activation may also be per se arrhythmogenic, via cytokine-mediated effects on cardiac electrophysiology. In particular, increasing evidence points to inflammation as a novel risk factor for QTc prolongation and related life-threatening arrhythmias, specifically Torsade de Pointes (TdP). Starting from the report of two cases of TdP occurring in PMR patients with active disease and elevated circulating IL-6 levels, we here reviewed literature data regarding heart involvement and arrhythmic events in PMR/GCA, as well as TdP risk in inflammatory diseases. Potential underlying mechanisms were dissected, by focusing on the driving role of inflammatory activation.
