Three patients of delayed extradural hematoma (EDH) were seen in the last one year among forty eight consecutively treated cases of EDH. All the three hematomas were evacuated. Awareness of this entity and a high degree of vigilance are strongly recommended to detect such cases. Repeat CT should always be done, especially after decompression by either surgical or medical means, recovery from shock or whenever there is evidence of even minimal bleeding under a skull fracture on initial CT scan. 相似文献

Background
The purposes of this cohort study were to establish how frequently people with physician-diagnosed diabetes self-reported the disease, to determine factors associated with self-reporting of diabetes, and to evaluate subsequent differences in self-management behaviour, health care utilisation and clinical outcomes between people who do and do not report their disease. 相似文献7.
Propensity score methods gave similar results to traditional regression modeling in observational studies: a systematic review 总被引:7,自引:0,他引:7
OBJECTIVE: To determine whether adjusting for confounder bias in observational studies using propensity scores gives different results than using traditional regression modeling. METHODS: Medline and Embase were used to identify studies that described at least one association between an exposure and an outcome using both traditional regression and propensity score methods to control for confounding. From 43 studies, 78 exposure-outcome associations were found. Measures of the quality of propensity score implementation were determined. The statistical significance of each association using both analytical methods was compared. The odds or hazard ratios derived using both methods were compared quantitatively. RESULTS: Statistical significance differed between regression and propensity score methods for only 8 of the associations (10%), kappa = 0.79 (95% CI = 0.65-0.92). In all cases, the regression method gave a statistically significant association not observed with the propensity score method. The odds or hazard ratio derived using propensity scores was, on average, 6.4% closer to unity than that derived using traditional regression. CONCLUSIONS: Observational studies had similar results whether using traditional regression or propensity scores to adjust for confounding. Propensity scores gave slightly weaker associations; however, many of the reviewed studies did not implement propensity scores well. 相似文献

The ideal age for bidirectional Glenn shunt (BDGS) as the first stage of staged Fontan is still not clear. Because of the
concerns regarding relatively high pulmonary vascular resistance during infancy, many centres would bridge through a systemic
to pulmonary artery shunt in this age group.
Patients and Methods We did a retrospective analysis of 28 infants who had undergone bidirectional Glenn shunt at our institute from February 200.
Results The mean age was 5 months (2.5–11) and the mean weight was 6.5 Kg (3.4–8.7). Boys dominated the group (25∶3). 7 infants had
previous procedures. In 3 patients, BDGS was done as a salvage procedure. Formal Cardiopulmonary bypass (CPB) was used in
all but 4 patients, in whom a right heart bypass was used. Superior Vena Cava (SVC) or innominate vein was cannulated in 12
patients and the rest were managed with temporary occlusion of SVC under deep hypothermic low flow bypass. 9 infants had bilateral
BDGS. The main pulmonary artery was interrupted in 12 and atrial septectomy was done in 10 patients. Additional procedures
with BDGS included Patent Ductus Arterious (PDA) interruption, Blalock Taussig (BT) shunt interruption, Left pulmonary arterioplasty,
Stansel procedure and redo TAPVC repair. The mean SVC pressure post operatively was 14 (10–24) and only 2 patients needed
pulmonary vasodilators in the post-oprative period. There is only one mortality in this series and the duration of chest tube
drainage and Intensive Care Unit (ICU) stay is comparable with the older age group.
Conclusion BDGS can be performed safely in infants more than 2 months of age electively or as a salvage procedure. It helps to avoid
one step in the form of aortopulmonary shunt and hence the ventricular volume overload associated with it. Further studies
are required to establish the growth potential of pulmonary arteries following an early BDGS.
