From June 1979 to July 1987, 84 acute burned patients with localized deep wounds involving tendon, nerve, vessel, bone and joint were treated by utilising 26 types of island axial-pattern cutaneous or musculocutaneous flaps. All flaps survived completely with a primary healing rate of 91.4%. All patients were divided into 'urgent' (within 48 hours), 'early' (within 2 weeks), or 'infected' groups according to the time interval between the burn injury and the surgery conducted. The primary healing rates for each groups were 100%, 94%, and 86% respectively. No significant differences exist between the axial-pattern cutaneous flap and musculo-cutaneous groups. The measures for minimizing infection including thorough debridement, groups. The measures for minimizing infection including thorough debridement, avoiding of circulatory compromises of the flaps, effectively postoperative drainage, and the use of antibiotics were discussed. Four types of newly developed axial-pattern cutaneous flaps as well as a super-long latissimus dorsi-external oblique abdominis-rectus abdominis combined musculocutaneous flaps were presented. 相似文献

Local cerebral glucose utilisation in chronic alcoholics: a positron tomographic study. 总被引:2,自引:0,他引:2 下载免费PDF全文

Using positron tomography, a study of regional cerebral glucose utilisation was performed prospectively in a highly selected group of six neurologically unaffected primary chronic alcoholics. In this group, neuropsychological, behavioural and CT scan anomalies were comparable with those previously reported in more extensive studies. With respect to age-matched control values, cerebral metabolic rate was not significantly modified in the selected cortical, subcortical and cerebellar regions of interest. However, the metabolic regional distribution index, which reflects the distribution pattern of glucose utilisation, was selectively and significantly decreased in the medio-frontal area, pointing to a limbic metabolic dysfunction apparently linked to chronic alcoholism. 相似文献

As far as the writers are aware, few studies on the changes of
blood and cerebrospinal fiuid sugar during hypoglycemia have been
made in schizophrenic patients. While our work was in progress, two
articles had come to our notice. In the paper by Dussik (1) the
blood and cerebrospinal fluid sugar values at the time of insulm coma
were determined, while in the communication by Day, Niver and
Greenberg (2) the course of changes in blood ar.d cerebrospinal fIuid
sugar after insulin was followed. The object of this paper is to
report the results of a number of individual and serial determinations
of both the bIood and cerebrospinal fluid sugar in schizophrenic
patients treated by insulin according to Sakel''s method (3). 相似文献

AIM: The aim of this study was to assess the effect of a specialised Vascular Unit upon the prevalence of ruptured aortic aneurysms in the same population catchments' area and associated mortality rates. METHODS: Setting: prospective computerised data collection from 1997 to today, retrospective from 1990-1996. Subjects: 108 aneurysms were operated upon from 1990-1996, compared to 317 from 1997 to Aug 2002. Main outcome measures: statistical analysis was done using SPSS statistics with Kaplan Meier life table curves and compared by the log rank test while the Mann Whitney test was used for comparison of mortality. RESULTS: The median values for ruptured aneurysms per year were 5 for the early period, compared to 10 for the recent years, while the median values for both urgent and ruptured were 7 and 18.5 cases annually, respectively. The number of scheduled procedures increased by 500% in the second period, with median values of 7 and 36.5, respectively. In-hospital mortality according to category was 21% for scheduled, 31% for urgent and 69% for ruptured aneurysms in the early period, compared to 3.7%, 16% and 29% respectively, following the establishment of the Vascular Unit. CONCLUSION: Despite the five-fold increase in the total number of aortic aneurysm repairs (as expected), the number of ruptured aneurysms operated upon increased as well. There was just a trend for a reduction in the absolute numbers of ruptured aneurysms operated upon in the last 2 years. Mortality, on the other hand, decreased dramatically in all categories, with the overall 30-day mortality decreasing more than four-fold, from 40% to 9.3%, while the respective mortalities according to the category of intervention were 3.7% vs 21% for scheduled, 16% vs 35% for urgent and 29% vs 69% for ruptured aneurysms, with a P value of less than 0.01. However, there was no difference in the numbers of patients with ruptured aneurysm reaching the hospital (operated or not) between the two periods (median values of 11 and 10.5 annually). The presence of a Vascular Unit, although it achieves dramatically better results, is not associated with a reduction in the number of emergency proceduresaeat least in the intermediate termaedespite an expansion in the indications for surgery, increased awareness and prompt referrals (centralisation). 相似文献

OBJECTIVE: The aim of this study was to evaluate the usefulness of measurement of the angle between bilateral renal pelves on axial views in the prenatal ultrasonographic diagnosis of horseshoe kidney. METHODS: We retrospectively measured the renal pelvic angle in 19 fetuses with horseshoe and 20 fetuses with normal kidneys in the second and third trimesters. Renal pelvic angle was defined as the angle between the long axis of the renal pelves on the axial view of the abdomen. We compared the renal pelvic angles of horseshoe and normal kidneys with unpaired t-test. Taking 140 degrees as a cut-off value, we calculated the sensitivity, specificity and accuracy of pelvic angle measurement for the prenatal diagnosis of horseshoe kidney. RESULTS: The mean pelvic angles in the fetuses with horseshoe kidney were 116 degrees and 110 degrees in the second and third trimester, respectively. In the normal fetuses, the equivalent angles were 172 degrees and 161 degrees. The difference between the two groups was statistically significant (P < 0.01). Using 140 degrees as the discriminating criterion, the sensitivity, specificity and accuracy of renal pelvic angle measurement for the prenatal diagnosis of horseshoe kidney were all 100%. Fifteen of 19 fetuses with horseshoe kidney had no other abnormality. Four (21%) fetuses had severe complex abnormalities which were associated with trisomy 18 in three cases. CONCLUSION: Observation and measurement of the renal pelvic angle is a simple and useful method in the prenatal diagnosis of the horseshoe kidney. 相似文献
