[Aneurysm of superficial temporal artery in angiolymphoid hyperplasia lesions]. / Anévrisme de l'artère temporale superficielle au sein de lésions d'hyperplasie angiolymphoïde.

INTRODUCTION: Subcutaneous angiolymphoid hyperplasia with eosinophilia is a disease which usually affects small vessels of neck and facial area. CASE REPORT: A 44 year-old with cutaneous lesions corresponding to angiolymphoid hyperplasia with eosinophilia is reported. The lesions were located near the temporal region. This case was particular because of the development of an anevrism of the superficial temporal artery. DISCUSSION: Involvement of the superficial temporal artery by angiolymphoid hyperplasia with eosinophilia has been reported in only one case which simulated a Horton disease because of an occlusion of the temporal artery. The development of an anevrism of this artery in a patient with angiolymphoid hyperplasia with eosinophilia is a very unusual presentation of the disease which has not been previously reported.

Rate of intravenous thrombolysis for acute ischaemic stroke in the North-of-France region and evolution over time.

The proportion of patients with ischaemic stroke treated by intravenous (i.v.) recombinant tissue plasminogen activator (rt-PA) is an indicator of quality of stroke care. The objective of the study is to evaluate the rate of i.v. thrombolysis in the North-of-France region and its evolution over time. We determined the proportion of inhabitants treated by i.v. rt-PA in 2009-2010 (period A; 8 stroke units, no telemedicine) and 2012 (period B; population campaigns, 12 stroke units with telemedicine in 5). We used hospital registries from the 12 stroke units, and population-based data were collected in a subpopulation of 226,827 inhabitants (5.6% of the whole population). 1,563 inhabitants received i.v. rt-PA for stroke (period A: 835 in 24 months; period B: 728 in 12 months). Hospital and population data were similar. Annual rates of thrombolysis increased from 103 per million inhabitants [95% confidence interval (CI) 85-125] to 181 (95% CI 157-209; relative increase 76%, 95% CI 67-83%). This rate increased in 12 districts (significantly in 6), but the increase was greater in districts where new stroke units, telemedicine, or both were implemented. In conclusion, although the proportion of patients treated was already high in period A, there was still place for improvement. Implementation of new stroke units, extension of the telemedicine network and new population campaigns are necessary to improve the rate of thrombolysis in several areas, to ensure an equal access to treatment over the whole territory. The next step is now to determine whether this high rate of i.v. rt-PA delivery at the population level translates into clinical results.

Subcutaneous changes in dermatomyositis.

We report the case of a 42-year-old woman with concomitant panniculitis and dermatomyositis. Painful, indurated lesions on the buttocks, thighs, arms, abdomen and breasts were associated with proximal muscle weakness. Skin biopsy revealed lobular panniculitis, and vacuolar degeneration of epidermal basal cells. Direct immunofluorescence was negative. Serum muscle enzyme (creatinine-phosphokinase) levels were elevated, and electromyography demonstrated a myositic process. Muscle biopsy showed an inflammatory myositis. These results were consistent with dermatomyositis associated with panniculitis. Only five cases of this association have been reported previously. The relationship between these two conditions is discussed.
