Effectiveness of Photogem (R) activated by LED on the decontamination of artificial carious bovine dentin

The aim of this study was the evaluation of the effectiveness of photodynamic therapy on the decontamination of artificially induced carious bovine dentin, using Photoge(R) as the photosensitizer agent and an LED device as a light source. Dentin samples obtained from bovine incisors were immersed in sterile broth supplemented by Lactobacillus acidophillus 10(8) colony formation units (CFU) and Streptococcus mutans 10 8 CFU. Different concentrations of photosensitizer, PA = 1 mg/ml, PB = 2 mg/ml, and PC = 3 mg/ml, and two fluences, D = 24 J/cm(2) and D = 48 J/cm(2), were investigated. After CFU counting per milligram of carious dentin and statistical analysis, we observed that the photodynamic therapy (PDT) parameters used were effective for bacterial reduction in the in vitro model under study. The best result was achieved with the application of Photoge(R) at 2 mg/ml and photoactivated under 24 J/cm(2) showing a survival factor of 0.14. At higher photosensitizer concentrations, a higher dark toxicity was observed. We propose a simple mathematical expression for the determination of PDT parameters of photosensitizer concentration and light fluence for different survival factor values. Since LED devices are simpler and cheaper compared to laser systems, it would be interesting to verify their efficacy as a light source in photodynamic therapy for the decontamination of carious dentin.

Complicated pneumonias with empyema and/or pneumatocele in children

To investigate the incidence, procedure type, characteristics of pleural fluid and pneumatoceles, and evolution of pneumonia complicated with empyema and/or pneumatoceles. Review of 394 pediatric pneumonia in patients at S (a) over capo Paulo State University Hospital during 2 years. We studied those with complications such as pleural effusion and pneumatocele. There were 121 (30.71%) with complications such as pleural effusion and pneumatocele; these were significantly higher in infants. One hundred and six children were needle aspirated, of these 78 underwent drainage, and 15 observation only. From the drained, seven needed thoracotomy or pleurostomy. Fluid was purulent in 50%, and pneumatoceles were seen in 33 cases (8.3%) with spontaneous involution in 28 (85%). Pleural fluid culture was negative in 51% cases; in positive cultures, Streptococcus pneumoniae was the most common agent. Complicated pneumonia incidence was higher in the second year of life and more than 70% occurred before 4 years of age. Closed thoracic drainage was effective in over 90%. Large effusions and mediastinal deviations were submitted to more aggressive procedures. Pneumatoceles predominated in the under 3s and were generally evident in the first chest X-ray. Most cases had spontaneous pneumatocele involution, and in almost half the cases were still present at drain tube removal.

O consentimento informado: Qual o seu real valor na prática médica?

Trata-se de um artigo que comenta sobre a real importância do Termo de Consentimento Informado na prática médica. Este documento tem sido cada vez mais usado como uma prática defensiva, a fim de constituir provas para defesa de um eventual processo judicial de responsabilidade médica, desvirtuando assim a idéia original, que seria a de respeitar a autonomia do paciente e delimitar a responsabilidade médica. O documento tem como objetivo mostrar que o médico cumpriu com seu dever de informar. Seu grande valor reside nos casos onde existam riscos de danos irreversíveis ao paciente. Conclui-se, porém, que um prontuário bem elaborado onde se inclui o registro das informações que foram transmitidas, bem como o grau de participação dos pacientes e seus familiares nas decisões terapêuticas, também deve ter valor ético e jurídico semelhante do TCI.
