Efeito dos Parâmetros Técnicos na Dose e Qualidade de Imagem num Sistema de Radiografia Computorizada

Em radiologia, a qualidade diagnóstica está intimamente ligada à qualidade de imagens radiográficas. Sendo a qualidade de imagem (QI) o reflexo da exposição do paciente, a sua a maximização não pode ser conseguida a qualquer custo. É fulcral ter sempre em mente que uma boa QI pode significar maior exposição do paciente. Deste modo, a otimização é fundamental e deve-se guiar pela maximização da fração benefícios/riscos, sendo para isso necessário compreender os parâmetros técnicos que influenciam a dose e a QI. Neste trabalho foi feito um estudo dos efeitos dos parâmetros técnicos (tensão de ampola (kVp) e o produto da intensidade do feixe (mA) pelo tempo de exposição (s) (mA*s)) e da filtração adicional tanto na dose como na QI. A medição da dose, para diferentes valores de kVp, mA*s e espessura de cobre (Cu) usada na filtração adicional, foi feita utilizando uma câmara de ionização e um medidor do produto dose-área (DAP). Utilisando o fantoma CDRAD, a QI foi analisada através de Image Quality Figure (IQF) e parâmetros como contraste, ruído, razão sinal-ruído (SNR) e razão contraste-ruído (CNR). Verificou-se que, no modo manual de exposição, a dose varia de forma direta com kVp e mA*s e, no modo semiautomático, a variação é inversa entre o kVp e a dose. Mantendo fixo o kVp e mA*s, a redução da dose pode ser conseguida com recurso à filtração adicional. A QI é degradada quando o kVp aumenta e na presença da filtração adicional. Melhor QI está associada a maiores valores de dose. CNR é pouca efetada pela variação da dose. Com o aumento do DAP, o ruído diminui e a SNR aumenta, com elevada correlação.

KIT mutations and dose selection for imatinib in patients with advanced gastrointestinal stromal tumours.

A recent randomized EORTC phase III trial, comparing two doses of imatinib in patients with advanced gastrointestinal stromal tumours (GISTs), reported dose dependency for progression-free survival. The current analysis of that study aimed to assess if tumour mutational status correlates with clinical response to imatinib. Pre-treatment samples of GISTs from 377 patients enrolled in phase III study were analyzed for mutations of KIT or PDGFRA by combination of D-HPLC and direct sequencing of tumour genomic DNA. Mutation types were correlated with patients' survival data. The presence of exon 9-activating mutations in KIT was the strongest adverse prognostic factor for response to imatinib, increasing the relative risk of progression by 171% (P<0.0001) and the relative risk of death by 190% (P<0.0001) when compared with KIT exon 11 mutants. Similarly, the relative risk of progression was increased by 108% (P<0.0001) and the relative risk of death by 76% (P=0.028) in patients without detectable KIT or PDGFRA mutations. In patients whose tumours expressed an exon 9 KIT oncoprotein, treatment with the high-dose regimen resulted in a significantly superior progression-free survival (P=0.0013), with a reduction of the relative risk of 61%. We conclude that tumour genotype is of major prognostic significance for progression-free survival and overall survival in patients treated with imatinib for advanced GISTs. Our findings suggest the need for differential treatment of patients with GISTs, with KIT exon 9 mutant patients benefiting the most from the 800 mg daily dose of the drug.

A single high dose of oral Vitamin D3 is not enough to correct insufficiency and deficiency in a rheumatologic population

Introduction: Vitamin D plays a major role in bone metabolism and neuromuscular function. Supplementation with vitamin D is effective to reduce the risk of fall and of fracture. However adherence to oral daily vitamin D supplementation is low. Screening and correcting vitamin D insufficiency in a general rheumatologic population could improve both morbidity and quality of life in these patients with chronic painful disorders and at high risk of osteoporosis. After determining the prevalence of vitamin D deficiency in this population, we evaluated if supplementation with a single high dose of oral 25-OH vitamin D3 was sufficient to correct this abnormality. Methods: During one month (November 2009), levels of 25-OH vitamin D were systematically determined in our rheumatology outpatient clinic and classified into three groups: vitamin D deficiency (<10 µg/l), vitamin D insufficiency (10 to 30µg/l) or normal vitamin D (>30 µg/l). Patients with insufficiency or deficiency received respectively a single high dose of 300'000 IU or 600'000 IU oral vitamin D3. In addition, all patients with osteoporosis were prescribed daily supplement of calcium (1g) and vitamin D (800 IU). 25-OH vitamin D levels were reevaluated after 3 months. Results: Vitamin D levels were initially determined in 292 patients (mean age 53, 211 women, 87% Caucasian). 77% had inflammatory rheumatologic disease (IRD), 20% osteoporosis (OP) and 12% degenerative disease (DD). Vitamin D deficiency was present in 20 (6.8%), while 225 (77.1%) had insufficiency. Of the 245 patients with levels <30µg/l, a new determination of vitamin D level was available in 173 (71%) at 3 months (table 1). Conclusion: Vitamin D insufficiency is highly prevalent in our rheumatologic population (84%), and is not adequately corrected by a single high dose of oral vitamin D3 in more than half of the patients with IRD and DD. In patients with OP, despite association of a single high dose with daily oral vitamin D supplementation, 40% of patients are still deficient when reevaluated at 3 months.

High-dose daptomycin plus fosfomycin is safe and effective in treating methicillin-susceptible and methicillin-resistant Staphylococcus aureus endocarditis.

We describe 3 patients with left-sided staphylococcal endocarditis (1 with methicillin-susceptible Staphylococcus aureus [MSSA] prosthetic aortic valve endocarditis and 2 with methicillin-resistant S. aureus [MRSA] native-valve endocarditis) who were successfully treated with high-dose intravenous daptomycin (10 mg/kg/day) plus fosfomycin (2 g every 6 h) for 6 weeks. This combination was tested in vitro against 7 MSSA, 5 MRSA, and 2 intermediately glycopeptide-resistant S. aureus isolates and proved to be synergistic against 11 (79%) strains and bactericidal against 8 (57%) strains. This combination deserves further clinical study.
