Abstract
PURPOSE To report the mid-term outcomes of percutaneous cryoablation (PCA) performed as second-line therapeutic option of venous malformations (VM). MATERIAL AND METHODS From 2011 to 2015, PCA was offered in 24 patients (mean age: 31 years, range: 12-64) as second-line treatment for recurrence of symptoms after sclerotherapy and when resection was not possible (due to lesion location or previous failure) or refused by the patient. Adverse effects were recorded, disease-free survival (DFS) and local tissue control (LTC) rates were calculated based on symptoms and volume evolution. RESULTS Mean follow-up was 18.7 months (6-48). Nine (37.5%, 9/24) adverse effects occurred and three (12.5%, 3/24) were severe. Mean pain assessed by visual analog scale (VAS) was 41.7 mm (0-80) before treatment and 20.3 mm (0-80) (p=0.01) after. Mean volume decreased significantly after treatment from 22.4 cm3 (0.9-146) to 8.35 cm3 (0-81.3) (p<0.001). Pain recurred in nine patients and size of one lesion increased. The DFS and LTC rates were 54% [95%CI: 22.94-77.27] and 93.33% [61.26-99.03] at 24 months, respectively. Only VM volume >10 cm3 was associated with a higher risk of local recurrence (p=0.05). CONCLUSION PCA as second-line treatment appears to be safe and effective for local control of VM according to mid-term results. KEY POINTS • Percutaneous cryoablation of venous malformations appeared well tolerated. • Size of venous malformations decreased significantly after percutaneous cryoablation (p<0.001). • Pain decreased significantly after percutaneous cryoablation of venous malformations (p=0.01).

Abstract
A decade ago, we identified a novel gene, glomulin (GLMN) in which mutations cause glomuvenous malformations (GVMs). GVMs are bluish-purple cutaneous vascular lesions with characteristic glomus cells in the walls of distended venous channels. The discovery of the genetic basis for GVMs allowed the definition of clinical features to distinguish GVMs from other venous anomalies. The variation in phenotype was also highlighted: from a single punctate blue dot to a large plaque-like lesion. In this study, we screened GLMN in a large cohort of patients to broaden the spectrum of mutations, define their frequency and search for possible genotype-phenotype correlations. Taking into account 6 families published by others, a mutation in GLMN has been found in 162 families. This represents 40 different mutations; the most frequent one being present in almost 45% of them. Expressivity varies largely, without a genotype/phenotype relationship. Among 381 individuals with a mutation, we discovered 37 unaffected carriers, implying a penetrance of 90%. As nonpenetrant individuals may transmit the disease to their descendants, knowledge on the mutational status is needed for appropriate genetic counseling.

Abstract
The present report describes a case of percutaneous cryotherapy in a 36-year-old woman with a large and painful pectoral venous malformation. Cryoablation was performed in a single session for this 9-cm mass with 24 h hospitalisation. At 2- and 6-month follow-up, the pain had completely disappeared, and magnetic resonance imaging demonstrated a significant decrease in size. Percutaneous cryoablation shows promise as a feasible and apparently safe method for local control in patients with symptomatic venous vascular malformations.

Abstract
Pseudoxanthoma elasticum (PXE) is an autosomal recessive disease affecting tissues rich in elastic fibers such as the skin, retina, and cardiovascular system. Mutations in the ABCC6 gene are known to be causative in most patients. Generalized arterial calcification of infancy (GACI) is characterized by extensive hydroxyapatite deposits in the internal elastic laminae in large and medium-sized arteries, leading to arterial stenoses and early and severe myocardial ischemia. GACI has been found to be primarily caused by mutations in the ENPP1 gene. We report two brothers born to unrelated parents. The elder developed uncomplicated PXE in adolescence and harbored mutations in the ABCC6 gene. The younger child died of a condition strikingly reminiscent of GACI at 15 months of age. This case of GACI was independent of mutations in the ENPP1 gene but was probably related to ABCC6 mutations. We demonstrate that matrix Gla protein and fetuin-A, involved in PXE, are also expressed in this case of GACI. These proteins could act as local and systemic inhibitors to limit the extension of mineralization. This report emphasizes concurrently that ABCC6 may be a relevant candidate gene in some cases of GACI with no mutations in the ENPP1 gene, and that GACI may be an atypical and severe end of the vascular phenotype spectrum of PXE.

Abstract
BACKGROUND Immune suppression cause by HIV infection is a risk factor in the progression of leishmania diseases. In Burkina Faso atypical clinical presentations of leishmaniases have been observed among people living with HIV. The goal of this study was to describe clinical and evolutionary aspects of cutaneous leishmania and HIV co-infection among patients followed at Ouagadougou University Hospital. PATIENTS AND METHODS This 16-month prospective study was carried out from January 2003 to April 2004 among HIV-seropositive patients with a diagnosed cutaneous leishmania infection. At baseline, infection and lesions were classified. Clinical diagnosis of cutaneous leishmania depended on finding parasites by microscopy in smears or tissue biopsies. Histological examinations were done if clinical and parasitological diagnosis were not concordant. Treatment consisted of three 21-day rounds of pentavalent antimonial, (Glucantime(R)). Clinical evolution was monitored at the end of each treatment round. RESULTS Thirty-two HIV-1 positive patients (16 women and 16 men) were included. Mean age was 35.5 (10-67 years old). Leishmania lesions had been evolving, on average, for 12 weeks. Eleven patients were taking HAART and 21 patients were taking cotrimoxazole prophylaxis against opportunistic infections. Cutaneous lesions were found: in the face (15 cases), torso (18 cases), upperlimbs (26 cases) and lower-limbs (28 cases). Observed clinical forms were: papulo-nodular (9 cases), ulcerative (14 cases), infiltrative (12 cases), lepromatous and diffuse (15 cases), psoriasis-like (5 cases), cheloid, histioid or kaposi-like (1 case each). Some patients presented more than one clinical form. Prognosis was satisfactory in 24 patients after the first treatment. Twelve patients relapsed after the first treatment, among those 10 were only taking cotrimoxazole. At the end of the third treatment, 24 patients were cured, 3 died and 5 were lost to follow-up. CONCLUSION Clinical polymorphism of cutaneous leishmania has been observed in HIV-patients, thereby increasing the risk of differential diagnosis.

Abstract
Pseudomonas aeruginosa is a ubiquitous environmental organism usually considered as opportunistic pathogen in immunocompromised subjects. However it can produce disease in healthy children, mainly on moist body sites. Familial, community and nosocomial outbreaks of cutaneous infections have been reported. Ecthyma gangrenosum is possible without bacteremia. P. aeruginosa is also the most common cause of otitis externa in swimmers and osteomyelitis after puncture wound of the foot.

Abstract
Herpetic gingivostomatitis (HGS) is the predominant manifestation of cutaneomucosal herpes in children with HSV1 primary infection before the age of 3 years. The infection is self limiting and lasts 10 to 14 days. Pain and dysphagia are particularly important during the first week of infection and may necessitate parenteral rehydratation and administration of antalgesics. HGS in the young child causes substantial morbidity leading to hospital and social costs (work stoppage for parents). The clinical course is generally benign with the exception of forms with important extension, eczema, herpeticum Kaposi-Juliusberg pustulosis observed at this age only in children with atopic dermititis. Other severe forms are observed in the neonate and immunodepressed subject, which can also be caused by HSV1. Forms with little or not clinical manifestation predominate and generally go undiagnosed, explaining the asymptomatic viral excretion observed in the saliva or other secretions (ocular, genital secretions). Despite the sterotypic nature of the clinical expression, HGS is still often undiagnosed both by general practitioners and pediatricians. This lack of diagnosis generally has few consequences due to the benign course in a few days, but the infection can have an important psychological and social leading to significant healthcare costs. Moderate and severe forms require medical care. Aciclovir should be prescribed if the diagnosis is made early (3 days) in combination with symptomatic care. Studies of the medical and economic impact of herpetic gingivostomatis should be conducted.

Abstract
UNLABELLED Onychomadesis describes complete nail shedding from the proximal portion; it is consecutive to a nail matrix arrest and can affect both fingernails and toenails. It is a rare disorder in children. Except for serious generalised diseases or inherited forms, most cases are considered to be idiopathic. Few reports in literature concern common triggering phenomena. We present four patients in whom the same benign viral condition in childhood appeared as a stressful event preceding onychomadesis. In each case, spontaneous complete healing of the nails was achieved within a few weeks. CONCLUSION Onychomadesis and/or onycholysis is a newly recognised complication in the course of viral infections presenting clinically as hand, foot and mouth disease, and because of mild forms, is probably underestimated.

Abstract
Our objective was to study possible etiologic factors of asymmetric periflexural exanthem of childhood (APEC) among a large panel of microbiologic agents not yet investigated. To do so, we designed a prospective case-control study using throat, stool, blood, and skin samples, and enlisted 37 children with APEC and 37 age-matched controls without eruption seen consecutively from February 1995 to April 1996 from a mixed referral center and community-based population. No interventions were done. Used as the main outcome measure was the differences in the two groups for microbiologic investigations. No significant statistical differences between cases and controls for virus and bacteria investigated were found. No microorganism was identified as a possible etiologic agent in any of the APEC patients. APEC is not a nonspecific cutaneous eruptive pattern to several common microbiologic agents. More sophisticated molecular approaches are needed to address its etiology.

Abstract
BACKGROUND Sjögren-Larsson syndrome (SLS) is a rare autosomal recessive disorder with worldwide distribution. It consists of ichthyosis, spastic diplegia and mental retardation caused by an enzymatic defect in fatty alcohol oxidation. OBJECTIVE To study the effects of dietary management on clinical outcome and plasma/red blood cell fatty alcohol and plasmalogen concentrations. METHODS To reduce fatty alcohol production, we reduced total fat intake to 30% of total intake of calories. To correct d 6 desaturase deficiency, we supplemented the diet with both n-3 and n-6 fatty acids to obtain a linoleic/linolenic acid ratio of 6 with low erucic acid rapeseed oil, plus high unsaturated fatty acids. We used gas liquid chromatography to assay blood cell membranes and plasma fatty alcohols/plasmalogens. RESULTS Two SLS infants with proven fatty alcohol/NAD+ oxidoreductase deficiency were studied. Good clinical results were obtained in one of the patients when dietary intervention was started in early infancy and correlated well with plasma fatty alcohol decrease. However, no clinical improvement was seen in the other patient who started later with low compliance. Acitretin therapy was necessary to control skin symptoms in this second patient. CONCLUSION Dietary intervention using the combined approach described here may improve fatty alcohol metabolism in SLS. However, only very early intervention seems clinically beneficial.

Abstract
Crusted scabies is mainly observed in children with immunosuppression or mental illness. Treatment is very difficult, and relapse is frequent after topical scabicidal therapy. We describe a case of crusted scabies, induced by long-term application of a topical corticosteroid, relapsing after topical treatment and dramatically improved by ivermectin. We suggest that ivermectin is a safe and effective alternative therapy for the treatment of severe Sarcoptes scabiei infestation in children unresponsive to conventional treatment.

Abstract
CASE REPORTS Two cases of linear and whorled nevoid hypermelanosis are reported. Cutaneous lesions (hyperpigmented macules along Blaschko's lines) appeared gradually after birth. Neurologic anomalies were detected in both cases (symptomatic in one, only cerebral MRI anomalies in the other). CONCLUSION This sporadic condition, probably caused by somatic mosaicism, must be differentiated from incontinentia pigmenti, Mac Cune-Albright disease and chimerism. Its situation among the Blaschko linear pigmentary anomalies (hypomelanosis of Ito) is discussed.

Abstract
BACKGROUND A type of neonatal cephalic pustulosis that is clinically similar to classic neonatal acne recently has been linked to Malassezia furfur infection. To correlate the mycological and clinical findings in neonates with cephalic pustulosis, we carried out a prospective case-control study in a neonatal unit from February to April 1997 using new techniques for classifying Malassezia species. OBSERVATIONS Nineteen patients with cephalic pustulosis and 19 controls younger than 45 days were studied among 161 consecutively hospitalized infants. Cultures from swabs and smears of pustules were obtained from patients, and swabs from healthy site-matched skin were obtained from controls. Three patients were excluded from the study because another cause of pustulosis was found. A blank sampling of pustules was obtained from 2 patients. Test results for 6 of 16 patients were positive for Malassezia sympodialis on contralateral nonpustular skin, and 4 of those patients also had positive cultures for M sympodialis. Cultures from 6 to 19 controls were positive (4 for M furfur and 2 for M sympodialis). The prevalence of Malassezia species increased with age, and the severity of the pustulosis was correlated with the isolation of M sympodialis. CONCLUSION Our data suggest that M sympodialis triggers the severe form of common cephalic pustulosis in infants with this benign disorder.

Abstract
Monilethrix is a rare human hair disorder with autosomal dominant transmission that can be caused by mutations in hair keratins. Up until now, pathogenic mutations in the type II hair cortex keratins hHb6 and hHb1 were restricted to a highly conserved glutamic acid residue Glu413 (Glu117 of the 2B subdomains) in the EIATYRRLLEGEE helix termination motif of the two keratins. The critical glutamic acid residue was substituted either by a lysine or, less frequently, by an aspartic acid residue. Here we report a novel mutation in a French monilethrix family, which again consists of a lysine substitution of another highly conserved glutamic acid residue, Glu402 (Glu106 of the 2B subdomain), in the EIATYRRLLEGEE motif of hHb1. Family members bearing the hHb1 Glu402Lys mutation exhibit a particularly variable disease phenotype. The pedigree comprises two infant members, one with pronounced dystrophic alopecia, follicular keratosis, and clear-cut moniliform hair, and one with no hair loss at all and moniliform hair detectable only by electron microscopy, as well as an adult individual without any clinically or electron microscopically detectable symptoms, but with clear historical proof of the disease.

Abstract
Pathogenic mutations in a large number of human epithelial keratins have been well characterized. However, analogous mutations in the hard alpha-keratins of hair and nail have not yet been described. Monilethrix is a rare autosomal dominant hair defect with variable expression. Hairs from affected individuals show a beaded structure of alternating elliptical nodes and constrictions (internodes). These internodes exhibit a high prospensity to weathering and fracture. Strong evidence that trichocyte keratin defects might underlie this hair disorder was provided by genetic linkage analyses that mapped this disease to the type-II keratin gene cluster on 12q13. All affected individuals from a four-generation British family with monilethrix, previously linked to the type-II keratin gene cluster, as well as three unrelated single monilethrix patients, exhibited a heterozygous point mutation in the gene for type-II hair cortex keratin hHb6, leading to lysine substitution of a highly conserved glutamic acid residue in the helix termination motif (Glu 410 Lys). In a three-generation French family with monilethrix of a milder and variable phenotype, we detected another heterozygous point mutation in the same glutamic acid codon of hHb6, which resulted in a conservative aspartic acid substitution (Glu 410 Asp). These mutations provide the first direct evidence for involvement of hair keratins in hair disease.
