[Advantages and controversies regarding physiologic electrostimulation of the heart in sinus node disease].

Unlabelled: Pacing mode in sinus node disease (SND) is one of controversies in cardiac pacing. We evaluated atrial pacing mode (AAI) in SND patients (pts). Between 1985 and 1994 AAI pacemaker was inserted in 179 pts due to symptomatic SND of varied etiology.

[Surgical treatment of cancer of the stomach].

Patients operated on for gastric carcinoma in the years 1949-1963 were compared with those treated in 1975-1982.

[Obstructive left colonic cancer. Retrospective analysis of the therapeutic attitude in a series of 40 recent cases].

In a series of 40 cancers involving the descending and sigmoid colon and producing true acute obstruction, the following were performed: 16 colostomies of first intention (including 11 palliative); 14 resections with colostomy (Hartmann type); 9 resection-anastomoses (including 3 protected); 1 attempt at laser treatment for non consent to surgery. Only 22 patients were theoretically suitable for anastomosis (18 contraindications due to invasive cancer or peritonitis); this was in fact carried out in 9 cases. Thus, if single stage surgery represents the ideal, it cannot be systematically applied; on the other hand, tumor resection can often be performed.

[Our experience using continuous atrial stimulation in sick sinus syndrome].

Temporary atrial pacing (AAI) was applied in 31 patients with sick sinus syndrome (S.S.S.
