Removal efficiency of nitrate, phosphate, fecal and total coliforms by horizontal subsurface flow-constructed wetland from domestic wastewater

Background: Constructed wetlands are systems designed based on the utilization of natural processes, including vegetation, soil, and their associated microbial assemblage to assist in treating different types of wastewater. Methods: Two local Appalachian plants (Louis latifolia and Phragmites australis) were planted into smallscale constructed wetlands to treat domestic wastewater in the North of Iran. The influent wastewater and the effluent from each wetland were sampled daily for 120 days. Experiments were conducted based on the mean ± standard deviation (SD) by analysis of variance (ANOVA). Results: It was found that nitrate, phosphate, fecal and total coliforms were reduced by 84.4%, 94.4%, 96.3%, 93.9% for P. australis and 73.3%, 64.0%, 94.4%, 92.1% for L. latifolia, respectively. Conclusion: According to the results, by using the HF-CW technology with L. latifolia and P. australis plants, the treated wastewater fully meets the wastewater discharge parameters of WHO standards

Les dermatoses infantiles avec atteinte oculaire (notre expérience en consultation conjointe de dermatologie et ophtalmologie)

Introduction : La consultation de Dermatologie-Ophtalmologie existe depuis quatre ans au CHU d Amiens. Nous rapportons notre expérience concernant les cas pédiatriques. Nous faisons un rappel des différentes pathologies rencontrées et proposons une classification d un point de vue dermatologique des dermatoses infantiles avec atteinte oculaire. Méthode : Etude descriptive, rétrospective des différents cas pédiatriques vus au cours de la consultation conjointe de Dermatologie- Ophtalmologie d Octobre 2009 à Septembre 2012. Résultats : 54 enfants ont été inclus. Les différentes pathologies rencontrées étaient : Dermatite Atopique (18), Rosacée (12), chalazions récidivants (4), Albinisme (4), Neurofibromatose de type1 (2), incontinentia pigmenti (2), et des pathologies moins frequentes : un naevus d OTA, un papillome verruqueux, un dermolipome, une hypomélanose d ITO, un xanthogranulome juvénile. 39 enfants étaient adressés par des ophtalmologistes, 14 par des dermatologues. Seulement un enfant été adressé par un pédiatre. Discussion : Notre travail a permis de souligner la valeur de cette consultation conjointe tant sur le plan diagnostic que thérapeutique. Il a permis de proposer l ébauche d une classification des dermatoses infantiles les plus connues avec une atteinte oculaire. Conclusion : Le bénéfice de cette consultation commune de Dermatologie Ophtalmologie peut être optimisé en diffusant l information concernant son existence, auprès des ophtalmologistes, dermatologues, et pédiatres. La consultation pluridisciplinaire marque la fin de l errance des malades d un spécialiste à l autre, celle-ci permettra enfin une prise en charge globale et optimisée du patient.INTRODUCTION: The multidisciplinary team Dermatology-Ophtalmology was established in October 2009 at the Department of Ophthalmology, Amiens University Medical Centre in order to provide global and more appropriate patient care. OBJECTIVE: To review the pediatric cases in the first four years of this interdisciplinary consultation. The secondary objectives are to review various pediatric disorders encountered in this consultation, and to propose a classification of pediatric dermatoses with eye involvement from a Dermatological point of view. METHODS: We realized a retrospective study of pediatric cases seen during this common consultation of Dermatology- Ophtalmology, from October 2009 until September 2012. RESULTS: This is a monthly consultation. Our study involved 54 children. The main disorders encountered in the setting were: Atopic Dermatitis (18), Rosacea (12), recurrent chalazion (4), Albinism (4), Neurofibromatosis type 1 (2), Incontinentia pigmenti (2), and other less frequent disorders. The majority of children were sent (39) by ophthalmologists, 14 by dermatologists. Only one child sent by pediatric. DISCUSSION: The multidisciplinary consultation helps establish an earlier diagnosis and better treatment adjustments than sequential consultations. CONCLUSION: Our study shows the importance of teamwork, for diagnosis, treatment, and follow-up of the patients. This teamwork could be improved through more exhaustive collaboration with other health care providers.AMIENS-BU Santé (800212102) / SudocSudocFranceF

Asymmetric periflexural exanthem of childhood and influenza virus infection.

Asymmetric periflexural exanthem of childhood (APEC) is a self-limited disease characterized by unilateral exanthem. The etiology is unknown, but a viral agent is suspected. Most often there is no formal proof of an associated viral etiology, but several associations between APEC and some viruses have been described. We report a 2-year-old girl with APEC associated with influenza A. This case allows us to provide an additional argument on a probable viral etiology of APEC and a possible etiologic role of influenza A

Efficiency of Catalytic Ozonation by MgO Nanoparticles to Remove Ceftriaxone from Aqueous Solution

Ceftriaxone is widely used for healing the infectious diseases. Not being treated in hospital wastewater treatment systems, this antibiotic has the possibility of entering into the aqueous environmental and the danger of microbial resistance in these environments also increases. This study aims to examine the efficiency of catalytic ozonation process by using magnesium oxide nanoparticles to remove ceftriaxone from aqueous solutions. In this study, the effect of pH, ozone dose, reaction time, catalyst dose and initial antibiotic concentration for ceftriaxone removal were studied using a cylindrical-shaped experimental reactor through semi-batch method. The residual concentration of ceftriaxone was determined by spectrophotometer. The experiment was carried out based on the one factor at a time method and finally the optimum efficiency of ceftriaxone removal and its desired conditions were determined. The best condition of the reactor obtained in pH 11, the catalyst dose of 1g/l, ozone dose of 18.384mg/min, pollution concentration of 10mg/l and reaction time of 30 min which showed 86% of ceftriaxone removal. Due to an increase in ozone retention time, the use of magnesium oxide nanoparticles in ozonation process also increased the antibiotic removal. It leads to a decrease in treatment costs because of a decrease in ozone consumption in an industrial scale

Investigating the Effect of Recycled Polymers application on bed Soil Quality of sanitary Landfills and Groundwater Pollution Control

Introduction and purpose: One of the important problems in the management of waste is the health and environmental hazards of the leachate leakage of urban waste landfills to groundwater. This research aimed to investigate the improvement of the landfill properties using recycled polymer. Methods: In this study, PET: Polyethylene Terephthalate and clay were mixed with the ratio of 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 and 1 wt%. Moreover, Moreover, its effect on the quality parameters of clay, including consolidation, settlement, shear stress, adhesion, and infiltration were determined in soil mechanics laboratory located in the city of Gorgan. All experiments were conducted based on American Society for Testing and Materials. Results: Results showed that the internal friction angle in clay and clay composed with polymer were 20.93 wt% and 30.3 wt%, respectively. Moreover, the compaction of clay decreased from 0.163 g/cm2 to 0.110 g/cm2. Permeability results showed that the use of PET decreased the  permeability of soil from 1.82 E-3cm/min to 1.57 E-3cm/min. Conclusion: The use of recycled polymer can improve the soil conditions of landfills in terms of permeability and resistance to leaching, which could reduce the volume and the recycling process of waste. Moreover, this issue contribute to the quality and strength of the substrate to prevent environmental contamination as well as groundwater polution

Acrodermatitis continua of Hallopeau response to optimized biological therapy

Acrodermatitis continua of Hallopeau, first described in 1890, is an uncommon variant of pustular psoriasis. It presents as a sterile pustular eruption of the tips of fingers and toes. The condition has a chronic, relapsing course and is often resistant to many anti-psoriatic therapies. In the following case, we present our experience of etanercept use in a 61-year-old man. Although initial therapy with high-dose etanercept achieved a rapid, sustained response and remission, the lesions relapsed a few months into a lower, maintenance dosage. This result prompted the use a second biotherapeutic agent ustekinumab, which resulted in complete remission, but required a higher dosage than recommended with reduced dosing intervals

Generalized pruritus in dysmetabolic hyperferritinemia treated by phlebotomy

This paper describes a case of pruritus caused by dysmetabolic hyperferritinemia treated by multiple phlebotomies.A 63-year-old man was followed for generalized pruritus, which was resistant to the usual treatments. He presented with metabolic syndrome. Physical examination showed only excoriations and lichenification on the skin. The serum ferritin was high at 1043 ng/ml, with transferrin saturation at 67%. The other biological investigations and genetic tests for hemochromatosis were negative.In spite of the dietary measures, the ferritin level was still high (853ng/ml). Magnetic resonance imaging confirmed hepatic iron overload.The association of hyperferritinemia, hepatic iron overload, and metabolic syndrome led to the diagnosis of dysmetabolic hyperferritinemia.Phlebotomies are an unusual treatment, but because the pruritus and hyperferritinemia were still present, phlebotomy wasinitiated. After 19 months, the patient reported improvement of his pruritus and normalization of ferritin levels
