Background
Tuberculosis is a major cause of morbidity and mortality globally. Recent scholarly attention to public health ethics provides an opportunity to analyze several ethical issues raised by the global tuberculosis pandemic. 相似文献83.

In a randomised, double-blind study, the effects of intramuscular injection of botulinum toxin type A (BtA) into the upper limb were compared with those of normal saline solution in 14 patients with cerebral palsy; their mean age was 9 years. Range of movement and function were assessed before injection and at 2 and 12 weeks after injection. BtA injection significantly increased maximum active elbow and thumb extension and significantly reduced tone at wrist and elbow. The hand grasp-and-release score improved, representing a modest functional change, but fine motor function, assessed by the ability to pick up coins, did not improve and in some cases deteriorated temporarily. The most notable subjective change was the cosmetic benefit of reduced involuntary elbow flexion. The tone-reducing effect of BtA was clinically detectable in comparison with the placebo and patients and parents perceived the change as beneficial. The median of changes in the treatment group was small but the range Was large, suggesting that BtA can be useful in selected patients. 相似文献

Background
Planning for the next pandemic influenza outbreak is underway in hospitals across the world. The global SARS experience has taught us that ethical frameworks to guide decision-making may help to reduce collateral damage and increase trust and solidarity within and between health care organisations. Good pandemic planning requires reflection on values because science alone cannot tell us how to prepare for a public health crisis. 相似文献85.

Background
As a number of commentators have noted, SARS exposed the vulnerabilities of our health care systems and governance structures. Health care professionals (HCPs) and hospital systems that bore the brunt of the SARS outbreak continue to struggle with the aftermath of the crisis. Indeed, HCPs – both in clinical care and in public health – were severely tested by SARS. Unprecedented demands were placed on their skills and expertise, and their personal commitment to their profession was severely tried. Many were exposed to serious risk of morbidity and mortality, as evidenced by the World Health Organization figures showing that approximately 30% of reported cases were among HCPs, some of whom died from the infection. Despite this challenge, professional codes of ethics are silent on the issue of duty to care during communicable disease outbreaks, thus providing no guidance on what is expected of HCPs or how they ought to approach their duty to care in the face of risk. 相似文献86.

Background
Cataract surgery remains a commonly performed elective surgical procedure in the aging and the elderly. The purpose of this study was to utilize time series methodology to determine the temporal and seasonal variations and the strength of the seasonality in age-related (senile) cataract hospitalizations and phacoemulsification surgeries. 相似文献87.

This study assesses the impact of an intervention known as the Ten Steps to Healthy Feeding: A Nutritional Guide for Children under Two on nutritional conditions and infant health in low-income families. Two hundred newborns were randomized to the intervention group and three hundred to the control group. Parents of the intervention group received nutritional orientation during the child's first year of life. Both groups received visits at 6 and 12 months and routine follow-up by their pediatricians. The results (n = 397) showed that the intervention was associated with a higher proportion of exclusive breastfeeding at 4 months (RR = 1.58; 95%CI: 1.21-2.06) and 6 months (RR = 2.34; 95%CI: 1.37-3.99) and breastfeeding at 12 months (RR = 1.26; 95%CI: 1.02-1.55) and a lower proportion of children with diarrhea (RR = 0.68; 95%CI: 0.51-0.90), respiratory problems (RR = 0.63; 95%CI: 0.46-0.85), use of medication (RR = 0.56; 95%CI: 0.34-0.91), and dental caries (RR = 0.56; 95%CI: 0.32-0.96) in the 12-16 month bracket. The intervention had no effect on the occurrence of anemia, hospitalization, or nutritional status. The results suggest that the nutritional orientation program led to positive changes in infant feeding practices and health conditions, but that it was insufficient to prevent iron deficiency anemia. 相似文献
