Unlabelled: Systemic sclerosis may be complicated by digital ulcers. Nailfold capillaroscopy on one finger might reflect an increased risk of digital ulcer (DU). In the present study we studied the correlations between a history of ulcer and capillary findings on the finger.

Methods: SCLEROCAP is a multicenter prospective study including consecutive scleroderma patients who have a yearly routine follow-up with capillaroscopy and digital blood pressure measurement. Capillaroscopy images were read by two observers blinded from each other, then by a third one in the case of discordance.

Background: Digital necrosis is rarer than lower limb necrosis and constitutes a medical or surgical emergency. Etiological evaluation is required. Cold agglutinin disease is a cause of digital necrosis but diagnosis is difficult.

The aims of this study were to: (1) analyse functional and vascular outcomes of conservative treatment for cases with absent pulse before reduction, whether patients showed limb ischaemia or not; and (2) identify factors associated with vascular complications.
Methods: Twenty-seven children with absent pulses on presentation were treated consecutively between 1999 and 2009.
Objectives: The aim of this work was to study inter- and intra-observer agreement for the diagnosis of scleroderma pattern by wide-field capillaroscopy.
Methods: Images were taken from 50 patients known to have SSc and 50 controls consulting for RP who did not have SSc. These images were rated simultaneously by 11 experienced vascular medicine physicians as scleroderma pattern or not.
Objectives: Subgroups of capillaroscopic scleroderma landscape have been correlated with stages of SSc: two groups for Maricq's classification (slow and active), and three for Cutolo's classification (early, active and late). We report inter- and intra-observer agreement for these classifications as a preliminary step in the multicentre prospective SCLEROCAP study, which aims to assess the classification and single capillaroscopic items as prognostic tools for SSc.
Methods: SCLEROCAP included 385 patients.
Background: Syncopes are frequent in the paediatric population. Most are benign, but rare cases are caused by cardiac life-threatening diseases. Syncope units developed in the adult population have demonstrated improvement in evaluation and treatment, with a reduction in hospitalization.

More recently, the use of video-capillaroscopy has allowed computer storage of capillaroscopic images (video-capillaroscopy), enabling evaluation of changes in capillaroscopic abnormalities during the follow-up of patients with systemic sclerosis or mixed connective tissue disease. Qualitative and quantitative assessment of the nail-fold dermal capillaries and of their organization can readily distinguish between a normal capillaroscopic pattern in primary Raynaud phenomenon and a specific sclerodermic pattern in secondary Raynaud phenomenon carrying a very high risk of systemic sclerosis.

Most countries have relaxed their quarantine measures and adopted a scheme combining vaccination of pets against rabies followed by a serological test to check the efficacy of vaccination. This new scheme has been strongly supported by the OIE, WHO and the European Commission to facilitate the free movement of people and pets around the world.

A blocking ELISA was evaluated and compared with the FAVN test and a validated in-house ELISA, using sera from foxes and raccoon dogs collected following oral vaccination campaigns in France and Estonia. Specificity reached 100% in sera from naïve animals.

Methods: To explore the feasibility and reproducibility of laser-Doppler flowmetry for CR measurement, we prospectively measured CR in 17 healthy subjects on the dorsum of the foot and pulp of the big toe. CR was defined as the sum of the venoarteriolar reflex (VAR), i.
Objective: To study the mid-term effects of Hormone Replacement Therapy (HRT) on cutaneous microcirculatory blood flow and reactivity in healthy postmenopausal women.
Design: In a double-blind placebo controlled randomized study, 16 healthy postmenopausal women received either placebo or HRT (micronized estradiol: 1 mg/day, day 1-28, promegestrone: 0.25 mg/day, day 14-28).
Homozygous sickle cell anaemia (SS disease) involves a high prevalence of skin ulcerations, and background experience concerning the cutaneous microcirculatory flux and reactivity in this disease is very limited. We investigated, by laser-Doppler velocimetry, the microcirculatory cutaneous blood flow and vasoreactivity in 17 patients with SS disease but no cutaneous trophic changes, vs. the corresponding values in 18 normal matched controls.

Experimental Design: The postural vasoconstrictive reflex was recorded in 34 patients with atherosclerotic occlusive disease of the lower limbs and 27 normal controls, using laser-Doppler flowmetry. Patients also had ankle and toe pressure measurements and transcutaneous oximetry (TcPO2).
