ABSTRACT
BACKGROUND: Measuring the slope of proximal tibiofibular joint may elucidate the anatomical structure and type of proximal tibiofibular joint, and evaluate the stability of proximal tibiofibular joint. OBJECTIVE: To investigate the measurement methods and clinical significance of the joint slope by comparing the slope measurement of bilateral proximal tibiofibular joint surface on X-ray and 64-row spiral CT reconstruction.METHODS: One hundred normal adult volunteers, including 50 males and 50 females, aged 18-90 years, were photographed in double knees via internal rotation to 30°, 45° and 60°, respectively and scanned with 64-row spiral CT, tibiofibular bone (including knee joints) was reconstructed. The included angle between proximal tibiofibular articular surface and the longitudinal axis of the fibula shaft, between the proximal tibiofibular articular surface and the horizontal line, were measured using an angle square.RESULTS AND CONCLUSION: There were great variations of the data in the same proximal tibiofibular joint measured by X-ray and spiral CT. X-ray results are affected by the site of photograph position, and the slope of articular surface is estimated, so the 64-row spiral CT is an accurate and convenient method to reconstitute the slope of proximal tibiofibular joints. Spiral CT could be used to distinguish the dislocation and instability of the proximal tibiofibular joint, accordingly reduce the clinical misdiagnosis.
ABSTRACT
Objective To discuss the effect of inhaling glucocorticosteroid in preventing asthma after bron-chiolitis. Methods 138 bronchiolitis infants were divided into three groups:the inhaling group A,tbe inhaling group B,the control group C. The inhaling group A and B were treated with glucocorticosteroid inhalation, but the inhaling group A had been inhaled pulmicort for six months,the inhaling group B for three months. All infants enrolled in the study and control group were followed up for average two years to observe the wheezing episodes. Results The fre-quency and persistence of wheezing was signfificanfly lower in interfered infants with glucecorticosteroid inhalation [(2.65±1.12)d,(2.89±1.06)d]than that of control group[ (4.06±1.17)d]in two years(all P<0.05) ,but no obvious difference exists between the inhaling group A and B (q= 1.59, P>0.05). Conclusion Glueocorticesteroid inhalation for three months can prevent recurrent wheezing after acute bronchiolitis.
