No full textWhat Is Causing This 5-Year-Old’s Itchy, Scaly, Pink Plaques? Rogerio Faillace, MD; Miguel Villacorta, BS; Fawn Winkelman, DO; and Elyse Julian, BS A 5-year-old girl presented with a 3-week history of multiple, discrete, pink, scaly plaques. The plaques were ovoid in shape, ranged from 0.5 to 3 cm in diameter, and were slightly raised, blanchable, and pruritic. The lesions were most appreciated over her right arm, where they coalesced into an erythematous, linear, raised plaque of 15 to 18 cm in length. Lesions also were appreciated over the scalp, arms, and legs bilaterally, as well as the torso, with greater involvement of the dorsal aspect. The parents denied any history of asthma or allergies in the girl, but noted that she had a history of eczema as an infant. Family history was negative for psoriasis. The lesions had begun on her right shoulder after an episode of pharyngitis and upper respiratory infection that had been treated conservatively. What do you suspect is causing these lesions? A. Guttate psoriasis B. Pityriasis rosea C. Inflammatory linear verrucous epidermal nevus D. Nummular eczema Are you ready to make the diagnosis?

Last Issue’s Answer: Guttate Psoriasis
No full textLast Issue’s Answer: Guttate Psoriasis Rogerio Faillace, MD; Miguel Villacorta, BS; Fawn Winkelman, DO; and Elyse Julian, BS A 5-year-old girl presented with a 3-week history of multiple, discrete, pink, scaly plaques. The plaques were ovoid in shape, ranged from 0.5 to 3 cm in diameter, and were slightly raised, blanchable, and pruritic. The lesions were most appreciated over her right arm, where they coalesced into an erythematous, linear, raised plaque of 15 to 18 cm in length (A). Lesions also were appreciated over the scalp, arms, and legs bilaterally, as well as the torso, with greater involvement of the dorsal aspect. The parents denied any history of asthma or allergies in the girl, but noted that she had a history of eczema as an infant. Family history was negative for psoriasis. The lesions had begun on her right shoulder after an episode of pharyngitis and upper respiratory infection that had been treated conservatively. The girl also was seen at a pediatric emergency department and had been treated with permethrin 5% cream for a presumed scabies infestation, but with no changes in the lesions. At follow-up, she had persistent pruritic lesions; rapid streptococcal antigen test results were negative, antistreptolysin O titer was elevated at 978 IU/mL, and throat culture was positive for group A streptococcus. Histologic results of a right arm lesion biopsy demonstrated neutrophils at the summits of parakeratotic scales, with suprapapillary epidermal plate thinning, a superficial perivascular infiltrate, and a focal area of hypogranulosis (B). This girl’s clinical presentation and the histologic findings were consistent with a diagnosis of guttate psoriasis with a linear involvement. The patient was treated with amoxicillin and topical mupirocin for 10 days and then was scheduled for a 3-month follow-up visit. She had developed several hypochromic lesions with lichenification, which were improving at the 3-month visit. Guttate psoriasis is a common form of psoriasis in children that presents with a generalized and diffuse distribution. It often develops 1 to 3 weeks after an upper respiratory infection, typically streptococcal pharyngitis.1 Rapid strep tests often demonstrate positive antistreptolysin O titers. The main differential diagnosis is pityriasis rosea, which can be differentiated from guttate psoriasis by the patient’s history, a history of a herald patch, the characteristic Christmas tree configuration on the trunk, and the appearance of a collarette of fine scales. No clear evidence supports the effectiveness of antibiotic treatment of guttate psoriasis, which usually is self-limited but does carry a risk of evolving into a chronic form of psoriasis.2 Linear psoriasis is a rare variant of psoriasis that is characterized by psoriatic lesions along the lines of Blaschko. The main differential diagnosis for linear psoriasis is inflammatory linear verrucous epidermal nevus, which often is present in the first months of life, is highly pruritic, and is resistant to antipsoriatic therapies, in contrast to linear psoriasis, which has a later onset, typically is asymptomatic, and responds well to therapy. The pathogenesis of linear psoriasis is unclear but may include a component of genetic mosaicism.3 Rogerio Faillace, MD, is an assistant professor of pediatrics at Nova Southeastern University College of Osteopathic Medicine in Fort Lauderdale, Florida.

Rogerio Bacono mokslo vizija
No full textStraipsnyje analizuojama XIII amžiaus pranciškonų mokslininko Rogerio Bacono mokslo samprata. Baconas suvokė mokslo svarbą reformuojant visuomenės gyvenimą, todėl jo tikslas buvo įgyvendinti tarpdisciplininę komunikaciją. Jis siekė sukurti universalią mokslo sistemą (scientia integralis), kurioje derėtų tiek Biblija, tiek filosofija, tiek gamtos mokslai. Jungiančioji grandis šioje mokslų sistemoje yra matematika ir eksperimentinis mokslas (scientia experimentalis). Pasaulio ir gamtos supratimas, Bacono teigimu, galimas tik apjungiant proto ir eksperimento pradus. Bacono mokslo vizija analizuojama remiantis jo traktatu „Opus Maius“. Reikšminiai žodžiai: Rogeris Baconas; Scientia integralis; Scientia experimentalis; Pažinimas; Matematika; Roger Bacon; Scientia integralis; Scientia experimentalis; Cognition; MathematicsThe article considers the concept of science as it is expressed by 13th century Franciscan scientist Roger Bacon. Hi realized the importance of science for the reformation of social life and therefore strived to promote interdisciplinary communication. He sought to constitute the universal system of science (scientia integralis) which would encompass Bible, philosophy, and natural sciences. The integrating core of this system would be mathematics and experimental science (scientia experimentalis). According to the author, the cognition of the world and nature was possible if and only if the principles of reasoning and experimenting were united. Bacon’s vision is analyses is based on his treatise "Opus Maius"
Informal gold mining and mercury pollution in Brazil
No full textThe Amazon region has been responsible for a major share of Brazilian gold production in recent years. The region has witnessed a sizable gold rush comparable only to the California gold rush last century. The gold rush has spawned a powerful informal mining sector and has attracted many people - some who have come to the region in search of wealth and some who were already there but were displaced from other, unsuccessful economicactivities. What these people encounter at the mining sites are dreadful living and working conditions. Gold mining also causes substantial environmental problems, which may persist whether gold deposits do or not. The author discusses the environmental effects of gold mining in the region, focusing on mercury pollution. Mercury, an important input in gold extraction, is being discharged into the atmosphere and the rivers at alarming rates. The environmental costs of the present extraction, is being discharged into the atmosphere and the rivers at alarming rates. The environmental costs of the present extraction technology will be faced primarily by future generations, because of natural chemical processes. Although removing the mercury already discharged from the Amazonian environment may be an enormous task, at least future discharges should be curtailed through the use of appropriate technology, environmental education, and a combination of command and control measures and market-based incentives. The author describes the gold extraction process and the extent of mercury use and contamination. He analyzes key elements of the environmental problem, especially the informal miner and the fish economy. Finally, he suggests a combination of command and control regulations and market-based incentives adapted to the informal gold mining economic environment. He emphasizes the need for an education campaign about the perils of using mercury and the availability of more appropriate, and inexpensive, alternative extraction technologies.Mining&Extractive Industry (Non-Energy),Montreal Protocol,Water and Industry,Coastal and Marine Resources,Primary Metals
UN Peace-Building, Transitional Justice and the Rule of Law in East Timor:The Limits of Institutional Responses to Political Questions
No full textA series of UN peace-building missions have taken the leading role in reconstructing the rule of law in East Timor, most notably through the hybridised Special Panels trials from 2000 to 2005 and ongoing hybridised participation in prosecution and judging in the years since then. While UN peace-building doctrine place great faith in transfusions of international expertise in the institutions of justice to secure their autonomy, the experience in East Timor has been one of consistent governmental interference to restrain politically sensitive prosecutions and systematic pardon of those convicted of committing crimes of political violence. Beginning with the thwarted prosecution of Indonesian generals accused of crimes against humanity before the Special Panels, and moving on to consider episodes of prosecutorial interference and systematic pardon in trials dealing with crimes committed during serious civil unrest in 2006 and attempted assassinations of the President and Prime Minister in 2008, this article examines the UN's ongoing failure to secure the autonomy of the judicial institutions it is mandated to assist. It cites a preoccupation on the part of the UN with the institutional aspects of the rule of law which has been emphasised at the expense of the more contentious cultural and behavioural aspects of the rule of law at a political level which are essential if the institutions of justice are to operate independently
Modelling hydrodynamic interactions between deformable droplets
No full textDeposited with permission of the author. © 2007 Rogerio Manica.Understanding deformations during interaction of colloidal or nano droplets. has important implications in a wide range of applications such as flotation collection and emulsion stability. The present work is important and necessary because current models are unable to properly describe recent experimental results obtained using the Atomic Force Microscope (AFM) and Surface Force Apparatus (SFA). We revisit and improve on theories involving interacting deformable droplets. A detailed theoretical model of the experiments, which accounts for surface forces, hydrodynamic interactions, droplet deformation and AFM cantilever detection, has been developed. The new feature of the model is the use of matched asymptotic expansions to derive a new boundary condition at constant volume to obtain results that are independent of the size of the computational domain. The AFM experiments provide measurements of dynamical forces between two interacting droplets as well as between a drop and a colloidal particle of micrometre radii in solution when they are driven together and then are retracted from each other. The SFA experiments measure (time dependent) surface profiles of a millimetre size mercury drop interacting with a mica surface. Different configurations have been studied including mechanical and electrical perturbations to a thin film stabilized by double layer repulsion. Interesting experimental features were observed when approaching or retracting the mica from the mercury drop

No full textVerifica o método da Análise Institucional do Discurso (AID) como uma forma de tratamento para crianças com o diagnóstico de transtorno do espectro autista (TEA). Trata-se de uma pesquisa que apresenta a partir da análise do atendimento dessas crianças pela AID, como é conferido a elas um lugar de enunciação na cena discursiva do tratamento clínico, ainda que, em alguns casos, não falem. São apresentadas análises de 6 atendimentos, em situação de acompanhamento escolar ou atendimento clínico em consultório, com foco no resgate dos diferentes caminhos trilhados pelas crianças como efeito de suas terapias, tendo em vista a ideia básica do brincar como discurso e de seu caráter terapêutico. Também, como essa abordagem contribuiu com a redução dos sintomas associados ao TEA, mensurados pela escala diagnóstica Autistic Diagnostic Observation Schedule (ADOS-2). Tais atendimentos receberam supervisão sob orientação da AID, e foram registrados na ocasião em que ocorreram. Foi observado o protagonismo da criança na cena analítica, em sua história como ponto de partida para sua terapia, bem como os efeitos na terapêuticaIt verifies the Institutional Discourse Analysis (IDA) method as a form of treatment for children diagnosed with autism spectrum disorder (ASD). This research presents, based on the analysis of the assistance provided to these children by AID, how they are given a place of enunciation in the discursive scene of clinical treatment, even though, in some cases, they do not speak. Analyzes of 6 appointments are presented, in a situation of school monitoring or clinical assistance in the office, with a focus on recovering the different paths taken by children as an effect of their therapies, bearing in mind the basic idea of playing as discourse and its therapeutic character. Also, how this approach contributed to the reduction of symptoms associated with ASD, measured by the Autistic Diagnostic Observation Schedule (ADOS-2) diagnostic scale. Such assistance received supervision under the guidance of the AID, and were recorded at the time they occurred. The child\'s protagonism in the analytic scene was observed, in its history as a starting point for its therapy, as well as the effects in the therap
