[Digital ischaemia with fingertip ulcers during ipilimumab therapy]. / Ischémie digitale avec ulcération pulpaire sous ipilimumab.

BACKGROUND: Anti-cancer drugs have many adverse effects including vascular side effects. Herein we present the case of a patient presenting digital ischaemia with high imputability of ipilimumab. OBSERVATION: A 47-year-old male patient was treated for popliteal melanoma, initially stage IIIA but which subsequently became metastatic (stage IV), and for which ipilimumab was given after the failure of two lines of chemotherapy. During the 4th course of ipilimumab, the patient developed autoimmune hepatitis. Ipilimumab was suspended. Three months later, he developed a drug-like neuropathy followed one month later by ulceration of the right index finger. Causes of embolic, autoimmune and occupational origin (thrombotic microangiopathy, thrombosed aneurysm) were rapidly ruled out. Although a paraneoplastic origin could not be formally excluded, drug-induced immune disorder remained the most plausible origin. DISCUSSION: This is the first reported case of digital ulceration under ipilimumab.

[Characteristics of chronic wounds in substance abuse: A retrospective study of 58 patients]. / Caractéristiques des plaies chroniques chez les toxicomanes : étude rétrospective de 58 patients.

BACKGROUND: Drug addiction causes chronic wounds (CW) responsible for severe complications. Very few studies are available on this topic. The aim of our study was to describe the demographic, clinical and etiological characteristics as well as the course of CW in drug addicts. PATIENTS AND METHODS: This was a retrospective and prospective multicenter study including all drug addicts with CW. RESULTS: We included 58 patients (17 prospectively), 84.5% of whom were male, of median age 43 years, presenting multiple CW as a result of intravenous (78.2%), inhaled (41.1%) and/or snorted (20%) drug abuse. Addiction to opioids (68.4%), cocaine (47.4%) and/or cannabis (40.4%) was ended and/or treated through substitution in 79.3% of patients. CW were fibrinous and necrotic (42.9 to 53.6%), recurrent (54.2%), and in some cases had been present for more than 1 year (61.5%). Intravenous drug addiction was associated with large, fibrinous, ulcers in a setting of venous and lymphatic insufficiency (74%). Only 23% of these wounds involved the upper limbs. Necrotic ulcers associated with clinical arteriopathy were described mainly with inhaled addiction. Abscesses (50%) and erysipelas (29.3%) were the most common cutaneous complications. After 3 months, 50% of CW were improved and 29.2% of patients were lost to follow-up. DISCUSSION: Drug abuse-related CW occurred preferentially in young men with history of intravenous abuse. For the most part, CW were seen on the legs and were associated with venous and lymphatic insufficiency, and the resulting major risk for cutaneous infection increased morbidity and mortality in this population in whom medical follow-up is inherently complicated.

The digital thermal hyperemia pattern is associated with the onset of digital ulcerations in systemic sclerosis during 3 years of follow-up.

OBJECTIVES: One of the most important skin complications in systemic sclerosis (SSc) is digital ulceration. Local thermal hyperemia (LTH) in the skin is a biphasic response to local heating involving both neurovascular and endothelial responses. Since LTH is abnormal in SSc patients, we aimed at testing whether LTH could be a prognostic tool for the onset of digital ulcers. METHODS: We prospectively enrolled 51 patients with SSc. Nailfold capillaroscopy and LTH were recorded at baseline, and patients were followed for 3 years. RESULTS: No patient with a LTH peak/plateau ratio ≥1 (n=19) developed digital ulcerations during the 3 year follow-up (100% negative predictive value), while 6 out of 32 patients with a LTH peak/plateau ratio <1 at enrolment presented with finger pad ulcerations within 3 years (p=0.05). In contrast, when lidocaine/prilocaine was applied to the finger pad, no relationship between thermal hyperemia and digital ulcerations was observed. CONCLUSIONS: A LTH peak/plateau ratio on the finger pad greater than 1, which can easily be determined in routine clinical practice, could be used to reassure patients, whatever the subtype of SSc, about the low probability of future digital ulceration. However, the prognostic value of this parameter should be confirmed in a larger cohort.

Abnormal amplitude and kinetics of digital postocclusive reactive hyperemia in systemic sclerosis.

OBJECTIVES: Postocclusive reactive hyperemia is mediated by two major mediators: sensory nerves and endothelium-derived hyperpolarizing factors. We hypothesized that the skin microvascular response to 5 min ischemia would differ depending upon the hand location in patients with systemic sclerosis (SSc), primary Raynaud's phenomenon (PRP) and healthy controls. METHODS: Fifteen patients with SSc, 15 sex- and age-matched patients with PRP and healthy controls were enrolled. Their right hands were subjected to 5 min ischemia followed by a postocclusive hyperemia test, with local microcirculation monitoring by laser speckle contrast imaging on the dorsal face of the hand. RESULTS: Postocclusive reactive hyperemia was abnormal in terms of peak and area under the curve (AUC) on all fingers except the thumb in patients with SSc and PRP compared with controls. In contrast, the kinetics of the response was longer only in SSc patients, with mean (SD) time to peak on the index, middle and ring finger were respectively 72 (58), 73 (51) and 67 (47) s for SSc; 40 (20), 40 (20) and 36 (19) s for PRP; and 34 (30), 34 (30) and 29 (24) s for controls (P=0.009 for interaction). CONCLUSIONS: We observed decreased distal digital microvascular perfusion following 5 min of ischemia in patients presenting with PRP or SSc, while the kinetics was prolonged only in SSc. A dynamic assessment of digital skin blood flow using laser speckle contrast imaging following 5 min ischemia could be used as a tool to assess microvascular abnormalities in patients with Raynaud's phenomenon secondary to SSc.

Feasibility of performing treadmill walking test for patients with peripheral arterial occlusive disease by the advanced practice nurses.

AIM: The treadmill walking test with post-exercise pressure measurement can be used as a diagnostic test and could classify peripheral arterial disease of the lower limbs. It can also exclude the diagnosis allowing to raise the possibility of differential diagnoses. In this study, we assessed the feasibility of performing treadmill test by advanced practice nurse to assess suspected lower extremity peripheral artery disease patients. DESIGN AND METHOD: This is a longitudinal monocentric study to assess the feasibility of a treadmill walking test performed by an advanced practice nurse. The primary endpoint was the number of tests performed during this period. The secondary objectives were to evaluate the reasons for requesting the test, the main results obtained in terms of the test's contribution and diagnoses, and patients' clinical characteristics. RESULTS: From February to May 2023, amongst 31 patients who underwent the treadmill walking test, 4 tests were able to rule out peripheral arterial disease and to detect differential diagnoses. For the remaining 27 patients, 4 had stage IIa of the Leriche classification, 23 had stage IIb, 2 of which were associated with a narrow lumbar spine. In contrast to the usual report, the APN's report on the walking test included an identification of cardiovascular risk factors, as well as a possible medical reorientation linked to the correction of a detected cardiovascular risk factor. CONCLUSION: The treadmill walking test can be performed by an advanced practice nurse. He/She added a comprehensive/global patient management, with the detection of cardiovascular risk factors. This new profession led to an increase in the number of tests performed of more than 50% over the period and reduced the time to access the test.

Literature review of transcutaneous electrical nerve stimulation in peripheral arterial occlusive disease of the lower limbs.

The therapeutic challenge in peripheral arterial occlusive disease (PAD) is often to increase walking distance, improve pain or heal a wound when PAD is symptomatic. Walking rehabilitation or surgical revascularization techniques are limited. Others strategies as alternatives and/or complementary treatments are needed. Among alternative options, Transcutaneous Electrical Nerve Stimulations (TENS) could be of interest, both for improved walking distance or pain reduction. The Transcutaneous Electrical Nerve Stimulation (TENS) is a non-pharmacological, mini-invasive technique involving transcutaneous electrical stimulation. However, there are other transcutaneous electrical nerve stimulation techniques based on the principle of vagus nerve stimulation with different mechanistics. Trans-auricular Vagus nerve stimulation (Ta-VNS) is another TENS technique (electrode on the external ear) which relies on the anti-inflammatory pathways of efferent and afferent vagal fibers. We propose here to review the literature of mini-invasive electrical stimulations, whatever the anatomical zone concerned, in PAD. METHOD: The aim was to evaluate the use of non-invasive transcutaneous electrical stimulation therapies (regardless of location) in PAD of the lower limbs, whatever the disease grade. A review of the literature was carried out via a search of the MEDLINE/PubMed database from 1975 to 2023. The articles were selected via abstracts by checking (1) medical indications: PAD patients with claudication were retained, excluding neurological or venous claudication, PAD whatever the disease grade (intermittent claudication or critical limb ischemia [CLI]) and (2) non invasive electrical stimulations were considered (neuromuscular electrical stimulation and spinal cord stimulation were excluded) whatever the anatomical site. Non-electrical stimuli such as acupuncture and reflexotherapy were excluded. RESULTS: Only 9 items were selected, including 7 studies with TENS treatment on the calf, one with trans-auricular vagus nerve stimulation and one with electro-acupuncture points of stimulation. CONCLUSION: Even if the mechanisms involved are different, TENS on the calves or in the external ears show an improvement of walking distance in PAD patients with intermittent claudication. The results of the studies show few positive effects in arteriopathy but we should keep vigilant in the technics used since mechanisms are different and not fully understood. Electro-stimulation of the calf and external ear appears to be an easy-to-use and accessible therapeutic option, especially since some PAD patients are still failing to be released from pain, despite the rise of endovascular interventional techniques.

Evaluation of patients' and practitionners' satisfaction with the use of hypnosis during a thermal endovenous procedure.

INTRODUCTION: In the field of vascular surgery, hypnosis has been used in the creation of venous approaches but also as a complement to local anesthesia during more extensive vascular surgery, including the insertion of abdominal aortic aneurysm stents. The practice of thermal endovenous procedures seems to us to be conducive to hypnotic support in particular to reinforce hypnoanalgesia. METHOD: We present a prospective and monocentric observational study at the University Hospital of Grenoble with consecutive inclusions whose objective was to evaluate the interest and the satisfaction of the patients and practionners about the practice of hypnosis during procedures of thermal endovenous treatments. RESULTS: Among the 31 patients treated with endovenous laser, 27 accepted the hypnosis proposal, 16 had hypnosis considered as formal and 13 conversational hypnosis and 10 conversation only. Among them, 29% of patients considered that the hypnoanalgesia technique had enormously relaxed them and 19% "very relaxed"; 42% of patients considered themselves "good", 32% "very good" and 19% "extremely good" at the end of the procedure. Concerning the practitioners performing the endovenous procedure, more than half (51, 51%) considered that hypnoanalgesia relaxed the patient "moderately and/or a lot". The results were as a whole point to a high level of satisfaction on the part of patients and practitioners with the practice of procedures with various levels of hypnosis induction. Despite many biases, this study has the merit of concluding that the patients were very satisfied with the apprehension of these gestures as well as the practitioners, and this without any additional time during the procedure.

The Role of Food Insecurity and Dietary Diversity on Recovery from Wasting among Hospitalized Children Aged 6-23 Months in Sub-Saharan Africa and South Asia.

Background: Current guidelines for the management of childhood wasting primarily focus on the provision of therapeutic foods and the treatment of medical complications. However, many children with wasting live in food-secure households, and multiple studies have demonstrated that the etiology of wasting is complex, including social, nutritional, and biological causes. We evaluated the contribution of household food insecurity, dietary diversity, and the consumption of specific food groups to the time to recovery from wasting after hospital discharge. Methods: We conducted a secondary analysis of the Childhood Acute Illness Network (CHAIN) cohort, a multicenter prospective study conducted in six low- or lower-middle-income countries. We included children aged 6−23 months with wasting (mid-upper arm circumference [MUAC] ≤ 12.5 cm) or kwashiorkor (bipedal edema) at the time of hospital discharge. The primary outcome was time to nutritional recovery, defined as a MUAC > 12.5 cm without edema. Using Cox proportional hazards models adjusted for age, sex, study site, HIV status, duration of hospitalization, enrollment MUAC, referral to a nutritional program, caregiver education, caregiver depression, the season of enrollment, residence, and household wealth status, we evaluated the role of reported food insecurity, dietary diversity, and specific food groups prior to hospitalization on time to recovery from wasting during the 6 months of posthospital discharge. Findings: Of 1286 included children, most participants (806, 63%) came from food-insecure households, including 170 (13%) with severe food insecurity, and 664 (52%) participants had insufficient dietary diversity. The median time to recovery was 96 days (18/100 child-months (95% CI: 17.0, 19.0)). Moderate (aHR 1.17 [0.96, 1.43]) and severe food insecurity (aHR 1.14 [0.88, 1.48]), and insufficient dietary diversity (aHR 1.07 [0.91, 1.25]) were not significantly associated with time to recovery. Children who had consumed legumes and nuts prior to diagnosis had a quicker recovery than those who did not (adjusted hazard ratio (aHR): 1.21 [1.01,1.44]). Consumption of dairy products (aHR 1.13 [0.96, 1.34], p = 0.14) and meat (aHR 1.11 [0.93, 1.33]), p = 0.23) were not statistically significantly associated with time to recovery. Consumption of fruits and vegetables (aHR 0.78 [0.65,0.94]) and breastfeeding (aHR 0.84 [0.71, 0.99]) before diagnosis were associated with longer time to recovery. Conclusion: Among wasted children discharged from hospital and managed in compliance with wasting guidelines, food insecurity and dietary diversity were not major determinants of recovery.

Comparison between laser speckle contrast imaging and laser Doppler imaging to assess skin blood flow in humans.

OBJECTIVE: We tested the linearity between skin blood flux recorded with laser speckle contrast imaging (LSCI) and laser Doppler imaging (LDI), comparing different ways of expressing data. A secondary objective was to test within-subject variability of baseline flux with the two techniques. METHODS: We performed local heating at 36, 39, 42, and 44°C on the forearm of healthy volunteers, and measured cutaneous blood flux with LDI and LSCI. Biological zero (BZ) was obtained by occluding the brachial artery. We expressed data as raw arbitrary perfusion units (APUs) and as a percentage increase from baseline (%BL), with and without subtracting BZ. Inter-site variability was expressed as a within subject coefficient of variation (CV). RESULTS: Twelve participants were enrolled. Inter-site variability at baseline was lower with LSCI (CV=9.2%) than with LDI (CV=20.7%). We observed an excellent correlation between both techniques when data were expressed as raw APUs or APU-BZ (R=0.90; p<0.001). The correlation remained correct for %BL (R=0.77, p<0.001), but decreased for %BL-BZ (R=0.44, p=0.003). Bland-Altman plots revealed a major proportional bias between the two techniques. CONCLUSION: This study suggests that skin blood flux measured with LSCI is linearly related to the LDI signal over a wide range of perfusion. Subtracting BZ does not affect this linearity but introduces variability in baseline flux, thus decreasing the correlation when data are expressed as a function of baseline. Finally, systematic bias makes it impossible to assimilate arbitrary perfusion units provided by the two systems.

Treatment of low-flow vascular malformations by ultrasound-guided sclerotherapy with polidocanol foam: 24 cases and literature review.

OBJECTIVES: Treatment by sclerotherapy has been suggested as a first-line treatment of low-flow vascular malformations. This study reports our experience in treating low-flow vascular malformations by ultrasound-guided sclerosis with polidocanol foam at the Vascular Medicine Department in Grenoble, France. DESIGN: Retrospective single-centre consecutive series. MATERIALS AND METHODS: Between January 2006 and December 2009, we analysed the complete records of patients with symptomatic low-flow vascular malformations of venous, lymphatic or complex type (Klippel-Trenaunay syndrome, KTS) treated by ultrasound-guided sclerosis. The therapeutic indication was always validated by the Consultative Committee for vascular malformations of the University Hospital of Grenoble. All vascular malformations were classified according to the Hamburg Classification. The sclerosing agent was polidocanol used as foam. RESULTS: A total of 24 patients between 7 and 78 years were treated (19 venous malformations, three KTSs and two venous-lymphatic malformations). The concentrations of polidocanol used ranged from 0.25% to 3%. The average number of sessions was 2.3 (1-16). After a median follow-up at 5 months after the last session, 23 out of 24 patients reported a decrease in pain; in nine cases (37.5%), over 50% reduction in size was observed, and in 14 cases (58.3%), a reduction of less than 50% of the original size was obtained. Two minor side effects were reported. CONCLUSIONS: Treatment by ultrasound-guided sclerosis using polidocanol foam seems to be well tolerated and can improve the symptoms of low-flow malformations without the risks of more aggressive sclerosing agents, such as ethanol.

[Overt disseminated intravascular coagulation complicating a venous malformation]. / Une coagulopathie intravasculaire disséminée liée à une malformation veineuse.

INTRODUCTION: Coagulopathy related to venous malformations can be life threatening. This complication is little known and underestimated. CASE REPORT: We report the case of a 52-year-old female patient who presented with a left femoral fracture. She had a pre-existing muscular infiltrating venous malformation of the left hip. During surgery, she developed acute disseminated intravascular coagulation. The latter was probably a consequence of both surgery and localized intravascular coagulation that was unknown before the trauma. CONCLUSION: It is important to diagnose localized intravascular coagulation in venous malformations, since the risk of disseminated intravascular coagulation can be prevented by anticoagulant therapy.

Reproducibility and methodological issues of skin post-occlusive and thermal hyperemia assessed by single-point laser Doppler flowmetry.

OBJECTIVE: The primary objective of this study was to evaluate 1-week reproducibility of post-occlusive reactive hyperemia (PORH) and local thermal hyperemia (LTH) assessed by single-point laser-Doppler flowmetry (LDF) on different skin sites. We also evaluated spatial reproducibility of both tests on the forearm. Finally, we assessed the influence of mental stress and room temperature variations on PORH and LTH. METHODS: We performed PORH and LTH assessing skin blood flow on the forearm and on the finger pad with LDF. We repeated the sequence 1 week later. We also performed PORH and LTH during mental stress (Stroop test) and at room temperatures of 21 degrees C and 27 degrees C. Data were expressed as cutaneous vascular conductance (CVC), as a function of baseline and as a function of 44 degrees C vasodilation (%CVC(44)). Reproducibility was expressed as within subject coefficients of variation (CV) and intra-class correlation coefficients (ICC). RESULTS: Fourteen Caucasian healthy volunteers were recruited. Median age was 25 (2.7) and 50% were female. Median body mass index was 21.2 (5). PORH was reproducible on the finger, whether expressed as raw CVC (CV=25%; ICC=0.56) or as %CVC(44) (CV=24%; ICC=0.60). However, PORH showed poor reproducibility on the forearm. In the same way, LTH was reproducible on the finger pad when expressed as CVC (CV=17%; ICC=0.81) but not on the forearm. Spatial reproducibility was poor on the forearm. Elevated room temperature (27 degrees C) affected PORH and LTH on the finger pad (p<0.05) but not on the forearm. CONCLUSION: Single-point LDF is a reproducible technique to assess PORH and LTH on the finger pad when data are expressed as raw CVC or %CVC(44). On the forearm, however, it shows great inter-day variability, probably due to spatial variability of capillary density. These results highlight the need for alternative techniques on the forearm.

Excellent reproducibility of laser speckle contrast imaging to assess skin microvascular reactivity.

OBJECTIVE: We compared the inter-day reproducibility of post-occlusive reactive hyperemia (PORH) assessed by single-point laser Doppler flowmetry (LDF) and laser speckle contrast analysis (LSCI), and the reproducibility of local thermal hyperemia (LTH) assessed by LDF, laser Doppler imaging (LDI) and LSCI. We also tested whether skin blood flow assessment by LDF and by LSCI are correlated. METHODS: Skin blood flow was evaluated during PORH and LTH using LDF, LDI (for LTH only) and LSCI on the forearms of healthy volunteers, at a 7day interval. Data are expressed as cutaneous vascular conductance (CVC), as a function of baseline and scaled to the thermal plateau. Reproducibility is expressed as within subject coefficients of variation (CV, in %) and intra-class correlation coefficients (ICC). RESULTS: Twenty-eight healthy participants were enrolled in this study. The reproducibility of the PORH peak CVC was better when assessed with LSCI compared to LDF (CV=8%; ICC=0.76 and CV=30%; ICC=0.54, respectively). Inter-day reproducibility of the LTH plateau was better when assessed with LSCI or LDI than LDF (CV=15%, ICC=0.66; CV=17%, ICC=0.51 and CV=42%, ICC=0.28 respectively). Finally, we observed significant correlation between simultaneous LDF and LSCI measurements of the PORH peak CVC (R=0.54; p=0.001). CONCLUSION: The recently developed LSCI technique showed very good inter-day reproducibility for assessing PORH and LTH. Moreover, we showed significant correlation between LSCI and single-point LDF for PORH. However, more data are needed to evaluate the linearity between the LSCI signal and skin blood flow.

Ultrasound-guided sclerotherapy of the great saphenous vein with 1% vs. 3% polidocanol foam: a multicentre double-blind randomised trial with 3-year follow-up.

OBJECTIVES: The aim of this study was to compare the efficacy and side effects of ultrasound-guided foam sclerotherapy of the great saphenous vein using 1% and 3% polidocanol foam with a 3-year follow-up. DESIGN: A multicentre prospective double-blind randomised clinical trial comparing the efficacy of 1% vs. 3% polidocanol sclerosant foam. MATERIALS AND METHODS: Patients with incompetence of the great saphenous vein (GSV) in CEAP clinical classes C2-5 (CEAP, Clinical-Etiology-Anatomy-Pathophysiology), with or without incompetence of the sapheno-femoral junction, were included. The Turbofoam method was used to create 1% and 3% polidocanol foam, which was injected into the GSV under ultrasound guidance, with a volume not exceeding 10 ml. Further foam sclerotherapy was carried out at 6 weeks, 3 and 6 months if required to abolish persistent venous reflux. The main outcome measure was the absence of saphenous reflux as assessed by ultrasound imaging at 6 months, 1, 2 and 3 years. Clinical severity (Venous Clinical Severity score (VCSS)) and quality of life (the Chronic Venous Insufficiency Questionnaire (CIVIQ)) scores were assessed. RESULTS: A total of 143 patients were included; 1% group men = 18, women = 55, 3% group men = 19, women = 51. The abolition of venous reflux was: 1% group, 69% and 3% group, 85% at 6 months; 1% group, 79% and 3% group, 78% at 3 years (including additional injections at 6 months). Three asymptomatic thrombo-embolic events (2%) occurred. Local side effects (principally pigmentation and matting) were 9% in the 3% group and 6% in the 1% group at 3 years (N.S.). Clinical severity and quality of life scores improved by more than 20% at 6 months in both the groups, with no difference between the groups. CONCLUSIONS: This is the first randomised clinical trial of ultrasound-guided foam sclerotherapy which is a 3-year follow-up and shows equivalent efficacy of 1% and 3% sclerosant foam. CLINICAL TRIAL REGISTRATION NUMBER: 2006-07-05.

Sodium nitroprusside iontophoresis on the finger pad does not consistently increase skin blood flow in healthy controls and patients with systemic sclerosis.

OBJECTIVE: Sodium nitroprusside (SNP) iontophoresis is a commonly used technique to assess non endothelium-dependent skin microvascular function in the forearm. However, the lack of data on the finger pad is a limitation when studying diseases affecting the digits (e.g. systemic sclerosis, SSc). We thus aimed to validate this technique in the finger pad compared to the forearm in SSc patients and healthy controls. METHODS: Six SSc patients and six controls were recruited. SNP and NaCl iontophoresis were performed on the finger pad and the forearm, with and without lidocaine/prilocaine. Cutaneous blood flow was simultaneously monitored using laser Doppler flowmetry. RESULTS: In all subjects, iontophoresis of SNP induced hyperemia in the forearm, which was not affected by pretreatment with lidocaine/prilocaine. In contrast, no increase in cutaneous vascular conductance was observed in the finger pad in any subject (apart from one patient with SSc). CONCLUSIONS: The iontophoresis of SNP leads to a consistent, non axon reflex-dependent, increase in cutaneous vascular conductance in the forearm, both in patients with SSc and in healthy controls. On the finger pad however, such hyperemia was not consistent. As a consequence, other tools should be considered to assess non endothelium-dependent skin microvascular function in the finger pad.

[Circumscribed telangiectasic lesions of the upper limb: unilateral nevoid telangiectasia syndrome?]. / Lésions télangiectasiques circonscrites au membre supérieur: penser au syndrome des télangiectasies naevoïdes unilatérales.

Patients presenting skin disorders with a probably vascular origin are often addressed to the vascular medicine unit. In general, the diagnosis of telangiectasia is straightforward but in certain rare clinical forms may be misleading. We report the case of a female patient presenting unilateral circumscribed telangiectasia on the left arm. History taking revealed that these lesions were congenital and had become accentuated during a recent pregnancy. The unilateral localization was highly suggestive, following Blaschko's lines. We retained the diagnosis of congenital unilateral nevoid telangiectasia syndrome exaggerated by pregnancy and the consequent hyperestrogenism. While it may be rather easy to rule out medical emergencies such as purpura, identifying the etiology of telangiectasia may be quite difficult, implying a careful, precise and complete history taking. Unilateral nevoid telangiectasia is a rare entity to be recognized. The underlying pathogenic mechanism remains to be elucidated.

Interstitial granulomatous dermatitis: a misdiagnosed cutaneous form of systemic lupus erythematosus?

Interstitial granulomatous dermatitis (IGD) is a recently described, rare dermatological entity. The clinical features are diverse and the precise aetiology is unknown. We present a rare and atypical case of IGD in a patient with systemic lupus erythematosus (SLE). A 26-year-old woman had been diagnosed with SLE when she was 15 years old. The diagnosis was based on cutaneous, articular, pulmonary, haematological and immunological features. The patient presented with a cutaneous diffuse macular eruption on the limbs, appearing in a cockade (rosette) pattern with a violaceous centre and erythematous surround. The face and trunk were spared. The cutaneous histological features led us to consider a diagnosis of IGD. The lesions disappeared after 15 days of systemic steroid therapy. This case is a new clinical form of IGD with an atypical location and clinical presentation. IGD has usually been associated with drug-related adverse reactions and autoimmune diseases. Reports in the literature of IGD in patients with SLE are rare.

[Polidocanol induced cardiotoxicity: a case report and review of the literature]. / Toxicité cardiaque du polidocanol: rapport d'un cas et revue de la littérature.

OBJECTIVE: Polidocanol foam sclerotherapy is a treatment of symptomatic venous disease. This solution is highly valued by clinicians because of its high efficacy and excellent safety profile. Systemic adverse effects are rare. Some life-threatening reactions have been reported. We report a case of respiratory and cardiac arrest, and a literature review on the cardiac toxicity of polidocanol used within and outside their licensed indications. MAIN OUTCOME MEASURES: A 48-year-old woman, with a symptomatic venous disorder, CEAP grade C2, was treated by echosclerotherapy for a great saphenous vein. She developed a malaise and respiratory and cardiac arrest occurred within minutes after a 7 ml foam polidocanol injection. Cardiopulmonary resuscitation was immediately started before restoration of pulses. A literature search was done using the Medline database. RESULTS: Five cases of cardiac toxicity were reported with polidocanol, but four of them were used outside their licensed indications. Because of the very suggestive chronology and the lack of any other obvious etiology, this cardiac arrest was attributed to polidocanol. Initial ST-segment elevation and negativity of anaphylaxis markers suggest a direct myocardial toxicity. CONCLUSIONS: Clinicians should be aware of the possibility of little-known but potentially serious cardiac adverse reaction with polidacanol injection and be prepared to initiate cardiopulmonary resuscitation if needed.
