Whereas the knowledge of skin thickness is essential to determine microneedle length and ensure proper administration of and better responses to intradermal vaccines, very few figures are available, especially in infants and children. Using ultrasound echography, we investigated skin thickness in 384 children aged 4-7, 12-18, and 54-66 months at potential body sites for intradermal vaccine delivery: deltoid, suprascapular, upper back, and lumbar area. The mean epidermis plus dermis thickness was significantly higher at the suprascapular than at the deltoid site (1.29. mm vs. 1.22. mm) and remained relatively unchanged whatever the BMI, age, sex, and skin phototype. In the 43 children aged 54-66 months, the mean skin thickness was significantly higher in the upper than in the lumbar area (1.39. mm vs. 1.31. mm). In this study setting, the heterogeneity in skin thickness cannot be considered sufficient to indicate various microneedle lengths for various ages or injection sites. © 2011 Elsevier Ltd. Source

Objectives The short-term efficacy and safety of transcatheter closure (TCC) for the management of coronary artery fistulas (CAFs) was investigated in pediatric patients. Background CAFS are rare with potentially severe complications and their management is still a matter of debate. Percutaneous closure appears to be the treatment of choice in anatomically suitable vessels but limited data are available in the pediatric population. Methods This retrospective, observational, multicenter, national study included patients under 16 years of age who underwent TCC of a congenital CAF. Patients with additional congenital heart defect were excluded. Results 61 patients (36 girls, 25 boys) with a median age of 0.6 year [0-15.4] at diagnosis and 3.9 years [0-16] at procedure were included. The CAF was large in 48 patients (79%); it was distal in 23 (38%) and proximal in 22 (36%). Most patients (77%) were asymptomatic at diagnosis. Clinical signs of congestive heart failure were present in seven patients (11%). Perioperative complications included three cases of ST elevation myocardial infarction (exclusively during attempted closure of a distal CAF), three devices migrations, and one case of leg ischemia. One patient died after surgical closure of a large distal CAF that could not be closed by TCC. Follow-up data were collected for 43 patients (70%) for a median of 91 days [0-4,824]. The Kaplan-Meyer estimate for complete occlusion at 2 years was 73 ± 7.6%. Conclusion TCC in the pediatric population appears to be effective and associated with few complications. © 2015 Wiley Periodicals, Inc. Source

The main objective of this study was to assess the diagnostic performance of a set of three Mucorales quantitative PCR assays in a retrospective multicentre study. Mucormycosis cases were recorded thanks to the French prospective surveillance programme (RESSIF network). The day of sampling of the first histological or mycological positive specimen was defined as day 0 (D0). Detection of circulating DNA was performed on frozen serum samples collected from D-30 to D30, using quantitative PCR assays targeting Rhizomucor, Lichtheimia, Mucor/Rhizopus. Forty-four patients diagnosed with probable (n = 19) or proven (n = 25) mucormycosis were included. Thirty-six of the 44 patients (81%) had at least one PCR-positive serum. The first PCR-positive sample was observed 9 days (range 0-28 days) before diagnosis was made using mycological criteria and at least 2 days (range 0-24 days) before imaging. The identifications provided with the quantitative PCR assays were all concordant with culture and/or PCR-based identification of the causal species. Survival rate at D84 was significantly higher for patients with an initially positive PCR that became negative after treatment initiation than for patients whose PCR remained positive (48% and 4%, respectively; p <10-6). The median time for complete negativity of PCR was 7 days (range 3-19 days) after initiation of l-AmB treatment. Despite some limitations due to the retrospective design of the study, we showed that Mucorales quantitative PCR could not only confirm the mucormycosis diagnosis when other mycological arguments were present but could also anticipate this diagnosis. Quantification of DNA loads may also be a useful adjunct to treatment monitoring. © 2015 European Society of Clinical Microbiology and Infectious Diseases. Source

Hypophysitis is an inflammatory disorder of the pituitary gland and corticosteroids are usually recommended as the first-line treatment. Hypophysitis related to primary Sjögren syndrome (pSS) is uncommon. We describe the unusual case of a patient with infundibuloneurohypophysitis associated with pSS successfully treated with mycophenolate mofetil (MMF). We describe a case of a 60-year-old man with a medical history of pSS presented with central diabetes insipidus and panhypopituitarism. Magnetic resonance imaging (MRI) revealed a thickening of the pituitary stalk and intense enhancement of the posterior pituitary, pituitary stalk, and hypothalamus. We diagnosed infundibuloneurohypophysitis associated with pSS. Hormonal replacement was started immediately and MMF was introduced without corticosteroids. After 9 months of treatment, MRI of the pituitary revealed a complete regression of the nodular thickening of the pituitary stalk, with normal enhancement and appearance of the pituitary. The pituitary axes had completely recovered, whereas the diabetes insipidus was partially restored. Our findings suggest that MMF is an effective alternative to corticosteroids for the treatment of lymphocytic hypophysitis associated with an autoimmune disease. Furthermore, this report could contribute to extend the spectrum of the neurological and endocrinological manifestations of pSS. Copyright © 2016 Wolters Kluwer Health, Inc. All rights reserved.

Identification and characterization of biomarkers in prostate cancer are important for improving the diagnosis. The aim of this study was to determine differences in the expression of 4 genes according to the stage of malignancy in prostate cancer. We analyzed BRCA1, BRCA2, androgen receptor (AR) and IGF-I gene expression in a cohort of 98 prostate biopsies. We used TaqMan RT-qPCR for mRNA detection, and correlation with proteins was performed using immunohistochemistry. Among the 98 studied prostate biopsies, high heterogeneity in the expression of the 4 genes was detected among the different histological types. However, down-regulation of BRCA1 and BRCA2 mRNA was detected, particularly in the normal tissues. The expression of AR was dependent on the stage of the tumor. The IGF-I gene was specifically expressed in the tumor tissues. Upon comparison between protein and mRNA expression for BRCA1, BRCA2 and AR, we obtained a trend; however, this did not achieve statistical significance. Regarding IGF-I, a correlation between mRNA expression and staining intensity of the protein was found to be significant (p<0.012). The AR biomarker was found to be slightly correlated with the prostate cancer diagnosis (p=0.013). AR was found to be decreased in the tumors with a 43% sensitivity and 90% specificity. The relative risk of 2.05 (1.13-3.69) indicated a 2-fold higher chance of cancer occurence when AR was ≤0.206. Source
