ABSTRACT
Calcific tendonitis of the hand is a rare condition. We present a case where there was extensive calcification along the flexor digitorum profundus tendon of the little finger. The patient's symptoms resolved with non-operative management.

Periacetabular radiolucent lines (RLLs) on postoperative radiographs have been associated with early loosening of the acetabular component. It has also been shown that excessive migration of an implant corresponds to an increased incidence of later clinical failure. This study relates RLLs on anterior-posterior hip radiographs taken 10 days and 6 months postoperatively to implant migration detected by roentgen stereophotogrammetric analysis. We have shown that RLLs in DeLee and Charnley zone III in the first week postoperatively as well as at 6 months are positively and significantly (P < .05) associated with migration detected by roentgen stereophotogrammetric analysis. No significant association was found for zone I or II at either 10 days or at 6 months. Considering the limitations in observing RLLs, their presence in zone III appears to reflect on the mechanical stability of the acetabular cup from the beginning. This indicates that zone III, which represents the inferomedial aspect of the acetabulum, might have to receive special attention when preparing the acetabulum and implanting the acetabular cup.

Lipase from "Fusarium solani" FS1 was immobilized by covalent attachment to polyacrylamide beads and onto magnetized Dacron, retaining 12(per cent) and 97(per cent) of activity, respectively. Lipase was also entrapped within polyacrylamide beads, retaining 53(per cent) of activity. Investigations of the kinetic characteristics of the immobilized derivates using triolein as substrate showed that lipase immobilized onto polyacrilamide beads and Dracon did not follow Michaelis-Menten kinetics.
