Background
The functional outcome of surgically treated dislocated fractures of the distal radius is limited and does not correlate with radiographic results. Additional carpal lesions are assumed to be the cause. This study has evaluated which carpal lesions are associated with dislocated fractures of the distal radius.Material and methods
A total of 104 consecutive patients with dislocated fractures of the distal radius were included in the study. The injured wrist was examined by radiography, computed tomography (CT) and magnetic resonance imaging (MRI) to determine additional carpal lesions.Results
Radiographically 51 of the 104 fractures presented as type A according to the AO classification, 10 as type B and 39 as type C. The CT scan detected that only 5 of the 51 type A fractures were exclusively metaphyseal fractures. All type A fractures were associated with ligamental lesions in MRI.Conclusions
The results of the study confirm the hypothesis that every dislocated fracture of the distal radius is a combined carpal trauma associated with additional osseous and/or ligamental lesions. 相似文献42.

ObjectiveTo evaluate the prevalence of burnout and satisfaction with work-life integration among physicians and other US workers in 2017 compared with 2011 and 2014.Participants and MethodsBetween October 12, 2017, and March 15, 2018, we surveyed US physicians and a probability-based sample of the US working population using methods similar to our 2011 and 2014 studies. A secondary survey with intensive follow-up was conducted in a sample of nonresponders to evaluate response bias. Burnout and work-life integration were measured using standard tools.ResultsOf 30,456 physicians who received an invitation to participate, 5197 (17.1%) completed surveys. Among the 476 physicians in the secondary survey of nonresponders, 248 (52.1%) responded. A comparison of responders in the 2 surveys revealed no significant differences in burnout scores (P=.66), suggesting that participants were representative of US physicians. When assessed using the Maslach Burnout Inventory, 43.9% (2147 of 4893) of the physicians who completed the MBI reported at least one symptom of burnout in 2017 compared with 54.4% (3680 of 6767) in 2014 (P<.001) and 45.5% (3310 of 7227) in 2011 (P=.04). Satisfaction with work-life integration was more favorable in 2017 (42.7% [2056 of 4809]) than in 2014 (40.9% [2718 of 6651]; P<.001) but less favorable than in 2011 (48.5% [3512 of 7244]; P<.001). On multivariate analysis adjusting for age, sex, relationship status, and hours worked per week, physicians were at increased risk for burnout (odds ratio, 1.39; 95% CI, 1.26-1.54; P<.001) and were less likely to be satisfied with work-life integration (odds ratio, 0.77; 95% CI, 0.70-0.85; P<.001) than other working US adults.ConclusionBurnout and satisfaction with work-life integration among US physicians improved between 2014 and 2017, with burnout currently near 2011 levels. Physicians remain at increased risk for burnout relative to workers in other fields. 相似文献

South Africa Every Death Counts Writing Group Bradshaw D Chopra M Kerber K Lawn JE Bamford L Moodley J Pattinson R Patrick M Stephen C Velaphi S 《Lancet》2008,371(9620):1294-1304
South Africa is one of the few developing countries with a national confidential inquiry into maternal deaths. 164 health facilities obtain audit data for stillbirths and neonatal deaths, and a new audit network does so for child deaths. Three separate reports have been published, providing valuable information about avoidable causes of death for mothers, babies, and children. These reports make health-system recommendations, many of which overlap and are intertwined with the scarcity of progress in addressing HIV/AIDS. The leaders of these three reports have united to prioritise actions to save the lives of South Africa's mothers, babies, and children. The country is off-track for the health-related Millennium Development Goals. Mortality in children younger than 5 years has increased, whereas maternal and neonatal mortality remain constant. This situation indicates the challenge of strengthening the health system because of high inequity and HIV/AIDS. Coverage of services is fairly high, but addressing the gaps in quality and equity is essential to increasing the number of lives saved. Consistent leadership and accountability to address crosscutting health system and equity issues, and to prevent mother-to-child transmission of HIV, would save tens of thousands of lives every year. Audit is powerful, but only if the data lead to action. 相似文献

Bulky perneopentyloxy-pillar[5]arene (Pillar-1) was synthesized and its conformational mobility was investigated using variable-temperature 1H NMR spectroscopy. The host–guest interactions between Pillar-1 and n-octyltrimethylammonium hexafluorophosphate (OMA) were investigated, and the formation of a 1 : 1 complex was revealed via1H NMR. Planar-chiral isomers were synthesized via the reaction of a hydroxy-functionalized pillar[5]arene with chiral derivatization agent (S)-(+)-MTPA-Cl. The (Sp, R)-and (Rp, R)-forms of the pillar[5]arene diastereomers were isolated by HPLC, and their structures were analyzed by 19F NMR. HPLC measurements indicated that racemization did not take place at 40 °C for 72 h.Bulky perneopentyloxy-pillar[5]arene was synthesized. Complexation behavior and conformational mobility were investigated using 1H NMR spectroscopy. Isolation of planar-chiral pillar[5]arenes using a chiral derivatization agent were carried out. 相似文献

Some patients with autoimmune chronic active hepatitis as well as their disease-free first degree relatives show decreased suppressor cell activity of peripheral blood T lymphocytes. Studies were therefore undertaken in families ascertained by the presence of a single chronic active hepatitis patient to determine if this abnormality of immune regulation represents a genetic phenotype simply controlled by a gene or genes at a putative disease susceptibility locus and, further, if this locus showed linkage to either the HLA or the immunoglobulin constant region loci. In addition to determining circulating autoantibody status and genotyping for HLA and immunoglobulin allotypes, suppressor T cells were evaluated by surface markers and by determining their ability to suppress IgG secretion in vitro. The results suggest that immunoregulatory dysfunction in autoimmune chronic active hepatitis is a familial abnormality, but that this abnormality occurs independent of circulating autoantibody status and of the segregation of genes for HLA or immunoglobulin allotypes. 相似文献
