Removal of heavy metals by biosorption
Industrialization and urbanization have resulted in increased releases of toxic heavy metals into the natural environment comprising soils, lakes, rivers, groundwaters and oceans. Research on biosorption of heavy metals has led to the identification of a number of microbial biomass types that are extremely effective in bioconcentrating metals. Biosorption is the binding and concentration of adsorbate from aqueous solutions by certain types of inactive and dead microbial biomass. The novel types of biosorbents presently reviewed are grouped under fungal biomass, biomass of non-living, dried brown marine algae, agricultural wastes and residues, composite chitosan biosorbent prepared by coating chitosan, cellulose-based sorbents and bacterial strains. The reports discussed in this review collectively suggest the promise of biosorption as a novel and green bioremediation technique for heavy metal pollutants from contaminated natural waters and wastewaters
Importância do raio X e exame físico no diagnóstico da artrite psoriática e sua prevalência no Hospital Universitário Evangélico de Curitiba (HUEC) The importance of radiologic evaluation and physical examination in diagnosis of psoriatic arthritis and its prevalance in the Hospital Universitário Evangélico de Curitiba
FUNDAMENTOS: A artrite psoriática (AP) é doença inflamatória associada com a psoríase da pele ou das unhas, com fator reumatóide (FR) negativo e ausência de nódulos reumatóides. Pode ser extremamente agressiva, deixando o paciente incapacitado para realizar funções do dia-a-dia. A prevalência populacional é muito variável; historicamente oscila entre 2,6% e 7%, mas estudos recentes demonstram porcentagem variável de 23 a 69% na população com psoríase. O diagnóstico é de exclusão e, se realizado na fase inicial, oferece possibilidade de tratamento mais adequado, evitando complicações. O que define a presença da artrite é o exame físico adequado das articulações, já que o raio X pode estar normal. OBJETIVO: Este estudo tem a finalidade de avaliar a importância do raio X e do exame físico no diagnóstico da AP e sua prevalência nos pacientes com psoríase cutânea e ungueal do Hospital Universitário Evangélico de Curitiba. MATERIAL E MÉTODOS: Trinta pacientes com psoríase em acompanhamento nesse serviço foram submetidos a anamnese e exame físico minuciosos. Eles foram questionados quanto a alterações articulares, tempo e severidade de doença e comprometimento ungueal. Os que apresentavam queixas articulares foram encaminhados para investigação por exames complementares: hemograma, FR, VHS, e raio X da articulação comprometida. RESULTADOS: A maioria dos pacientes (56,5%) referiu atralgia; contudo apenas três apresentavam artrite. Dos indivíduos com AP, um mostrou raio X normal, mas o exame físico estava alterado. CONCLUSÃO: O exame físico é fundamental para diagnóstico da AP; o raio X não. A prevalência de AP foi de 10%.<br>BACKGROUND: Psoriatic arthritis (PA) is an inflammatory disorder associated with skin and nail disease, negative rheumatoid factor (RF) and absence of rheumatoid nodules. It can be a devastating and incapacitating condition. Its prevalence is highly variable, ranging from 2,6 to 7%; however, recent data shows prevalence as high as 23 to 69%. Its diagnosis is one of exclusion, and when detected early in the course of the disease gives chance to adequate treatment, thus avoiding its sequelae. The diagnosis is made by physical examination, laboratory and radiological evaluation. A normal radiological finding does not exclude the disease. OBJECTIVE: This study aims to evaluate the importance of a detailed physical examination associated with radiological findings in the diagnosis of PA and its prevalence in our institution. METHODS: Thirty patients with skin psoriasis were submitted to a thorough physical examination and radiological evaluation. All patients were inquired about articular complaints, time and severity of skin and nail disease. Those that presented any articular symptom were submitted to a laboratory evaluation with: Complete Blood Count (CBC), RF, Erythrocyte Sedimentation Rate (ESR) and radiography of the involved joint. RESULTS: The majority of patients (56,5%) presented arthralgia; however, only three patients had arthritis. Of those 3 that had PA, one presented a normal radiography but with an altered physical examination. CONCLUSION: The physical examination is an extremely important tool in the evaluation of patients with psoriasis. The radiological evaluation is not as important as the physical examination. The prevalence of PA was 10%
