    Notes: Abstract EISCAT observations of the interplanetary scintillation of a single source were made over an extended period of time, during which the orientation of the baselines between the two observing sites changed significantly. Assuming that maximum correlation between the scintillations observed at the two sites occurs when the projected baseline is parallel to the direction of plasma flow, this technique can be used to make a unique determination of the direction of the solar wind. In the past it has usually been assumed that the plasma flow is radial, but measurements of eleven sources using this technique have indicated conclusively that in at least six cases observed at mid or high heliocentric latitude there is a significant non-radial component directed in four cases towards the heliocentric equator and in two cases towards the pole.

    Notes: Abstract Background: Laparoscopic cholecystectomy (LC) significantly reduces the discomfort and disability typically associated with open cholecystectomy, but there is still room for improvement. Methods: In order to further reduce the trauma of access, we have introduced a technique of micropuncture laparoscopic cholecystectomy (MPLC) that utilizes three 3-mm cannulae in addition to the standard 10-mm cannula at the umbilicus. MPLC was performed in 25 patients (median age, 52 years; m/f, three of 22) with symptomatic cholelithiasis. Results: The operation was completed in all patients. The median duration of surgery was 75 min (range, 45–180). Sixteen patients were discharged the same day and nine patients the next day. All the patients had an uncomplicated recovery. Only eight patients requested postoperative analgesia while in hospital. Micropuncture exploration of the bile duct was carried out in one patient. Conclusions: MPLC is a feasible and safe technique that appears to improve on the benefits of LC; it makes the operation even more feasible as a day-surgery procedure.
