The purpose of this study was to evaluate the added role of a chemotherapeutic in transarterial chemoembolization (TACE) of intermediate-stage hepatocellular carcinoma (HCC). The issue is of major importance since, as suggested by recent evidence, hypoxia or incomplete devascularization of the tumor is a potent stimulator of angiogenesis, and there are not many papers supplying level one evidence confirming the value of a chemotherapeutic. The hypothesis was that since drug-eluting bead (DEB)-TACE is standardized and reproducible, a comparison with bland TACE can readily reveal the potential value of the chemotherapeutic. Two groups were randomized in this prospective study: group A (n = 41) was treated with doxorubicin DEB-TACE, and group B (n = 43) with bland embolization. Patients were randomized for tumor diameter. Patients were embolized at set time intervals (2 months), with a maximum of three embolizations. Tumor response was evaluated using the EASL criteria and alpha-fetoprotein levels. At 6 months a complete response was seen in 11 patients (26.8%) in the DEB-TACE group and in 6 patients (14%) in the bland embolization group; a partial response was achieved in 19 patients (46.3%) and 18 (41.9%) patients in the DEB-TACE and bland embolization groups, respectively. Recurrences at 9 and 12 months were higher for bland embolization (78.3% vs. 45.7%) at 12 months. Time to progression (TTP) was longer for the DEB-TACE group (42.4 +/- 9.5 and 36.2 +/- 9.0 weeks), at a statistically significant level (p = 0.008). In conclusion, DEB-TACE presents a better local response, fewer recurrences, and a longer TTP than bland embolization with BeadBlock. However, survival benefit and bland embolization with smaller particles must be addressed in future papers to better assess the clinical value.

Incidence and risk factors of all injuries in a population-based study among children. About 28 per 100 children got injured over a period of one year. There is evidence that younger paternal age and lower education may be associated with increased injury risk. Family related variables seem to be important risk factors for childhood injuries, whereas somatometric characteristics play minimal role.

Falls are a common cause of serious infant injuries, and nursery equipment is frequently involved in the injury-causing event.

Objective: To calculate the preventable fraction of unintentional childhood injury deaths in the United States. Design: Ecological study of cause specific unintentional childhood injury mortality rates across the 50 states (and the District of Columbia) of the United States (US) over the 10 year period 1989-98. Methods: The internet accessible database from the National Center for Injury Prevention and Control was used in order to estimate unintentional childhood (0-14 years) injury mortality rates by external cause and time trends over the study period for each of the US states and for the four major geographical regions of the country. In the principal analysis, a calculation was made of the fraction and absolute number of unintentional childhood injury deaths that could have been prevented annually if the mortality rate in the region with the lowest rate also existed in the remaining three. In another scenario, the lowest external cause specific unintentional childhood injury mortality rates from the 50 US states and the District of Columbia were summed to provide the ''ideal'' lowest conceivable unintentional childhood injury mortality rate from all causes. Ecological correlations between unintentional childhood injury mortality rates from specified external causes, median income, and percent of the population with a college degree were made. Main outcome measures: Unintentional childhood injury mortality rates by cause. Results: Unintentional childhood injury mortality rate declined by 3.5% per year in the country as a whole. If every region of the US had experienced the same injury rate as the Northeast, then one third of all unintentional childhood injuries would not have occurred.More optimistic scenarios indicate that up to two thirds of all unintentional childhood injury deaths could be prevented. Across states, unintentional childhood injury mortality is strongly inversely related to median income. Conclusions: About one third of all unintentional childhood injury deaths in the US are preventable with the means and resources available in the Northeastern states. Among the relevant characteristics in the Northeast region, in comparison with other US regions, are the higher education level of parents, the lower gun ownership, the higher population density that implies shorter distances traveled by cars, a better developed emergency medical system, and the existence of several injury prevention programs.

On the basis of plausible assumptions, a loan programme of infant car-restraints was shown to be particularly cost effective.
