    Notes: Abstract This report describes our data regarding repeated injection sclerotherapy using a newly designed over-tube. We treated 17 consecutive patients with esophageal varices, (3 acute, 6 elective and 8 prophylactic). An intravariceal injection of 5 per cent ethanolamine oleate was administered, using a newly designed transparent over-tube containing a second lumen for a flexible injection needle. This over-tube provides an easier, safer, shorter-in-time method of sclerosing esophageal varices. One of the 17 patients died as a result of liver failure associated with advanced cirrhosis and a concomitant hepatoma. Eradication of esophageal varices was attained in the remaining 16 patients, after an average of 5.0 injections over an average period of 5.8 weeks (range: 3–7 injections during 3–11 weeks). No complications, such as esophageal perforation or aspiration pneumonia were encountered. Recurrent variceal bleeding has not occurred during the 9 months follow-up.

    Notes: Abstract Thirty patients with esophageal varices, portal venous obstruction and a histologically proven normal liver underwent either one of 2 different types of surgery. Shunt surgery was performed on 20 patients: 9 had a mesocaval shunt, 3, a splenorenal shunt, 4, a left gastric venacaval shunt, and 4, a distal splenorenal shunt. Conversely, direct interruption was performed on the other 10 patients: 6 underwent an esophageal transection, and 4 underwent a resection of the proximal stomach. Re-hemorrhage occurred in 7 of the former 20 patients but not in any of the 10 on whom the direct interruption method was used. In 6 of these 7 patients who experienced rebleeding, subsequent direct interruption surgery led to control of the bleeding. One patient died of a variceal hemorrhage one month postoperatively. The total 10 year cumulative survival rate was 86.3 per cent. In the light of these findings, we believe that methods of direct interruption, such as esophageal transection, may well be the approach of choice for patients with esophageal varices caused by extrahepatic portal venous obstruction.

    Variability in the efficacy of delayed inducible resistance in mountain birch (1992)

    Notes: Abstract This paper summarizes the results from experiments during 12 years on effects of delayed inducible resistance of mountain birches (Betula pubescens Ehrh. ssp. tortuosa (Ledeb.) Nyman) on performance of a geometrid, Epirrita autumnata (Bkh.). Manual defoliation usually reduced significantly pupal mass of E. autumnata the next summer. The years interacted significantly with the defoliation treatment indicating variation among years in the responses of trees of larvae, or that the methodological differences between different experiments may have affected the results. Potential methodological sources for the annual variability were discussed and found unlikely. In addition, the efficacy of defoliation treatment in reducing the pupal mass was greatest when foliage quality in control trees was best, suggesting a contribution of biological causes to the annual variability.

    Crowding-triggered phenotypic responses alleviate consequences of crowding inEpirrita autumnata (Lep., Geometridae) (1988)

    Notes: Summary CrowdedEpirrita larvae had shorter larval periods than, and similar pupal masses to, their solitary siblings when reared on low quality diets. When fed on high quality diets, pupal masses of crowded larvae were lower than in singletons, and there was no difference in larval period. Because changes in food availability (absolute shortage, induced resistance in foliage) are caused by high larval densities in the field, crowding-triggered phenotypic changes may helpEpirrita to overcome detrimental consequences of high larval density. Pupal period was longer in crowded larvae than in singletons and crowded adults emerged later than their solitary siblings. Eggs of late emerging moths eclosed late in the ensuing spring, which coincides with delayed leaf flush in the year after defoliation. The reason for the faster growth of crowded individuals on poor diets was higher intake albeit less thorough processing of food in crowded, but not in solitary, larvae. On good diets solitary individuals tended to consume more than crowded larvae but there was no difference in processing. Predicted differences of host plant use between stealthy and opportunistic types of herbivores (sensu Rhoades 1985) were generally found between solitary and aggregated larvae on poor but not on good diets. The group response could not be explained by benefits to the group although the assumptions of Wilson's model of group selection were satisfied.

    Notes: Summary Between April and August 1991, 83 Japanese patients with symptomatic gallstones underwent laparoscopic cholecystectomy in our clinics. A prospective randomized trial was carried out to examine the safety, efficacy, and complications of the two techniques, pneumoperitoneum vs an elevating method using a U-shaped retractor. Forty-two patients were randomly allocated to the pneumoperitoneum (P) group and 41 to the U-shaped retractor (U) group. These two groups were well matched with respect to age, sex, etiology, and the severity of the chronic cholecystitis. Laparoscopic resection was successful for 88.1% (37/42) in the P group and 100% (41/41) in the U group. In patients with a severe fibrotic gallbladder, the rate of success was significantly higher (P〈0.05) in the U group (100%, 6/6) than in the P group (11.8%, 1/6). In the moderately inflamed group, the operation time (mean±SD) was significantly (P〈0.01) less in the U group (58.7±22.7) than in theP group (87.3±18.3). With the U-shaped retractor the usual surgical instruments can be used, and a rapid and safer laparoscopic cholecystectomy can be carried out. We prefer this approach to a pneumoperitoneum for patients with an inflamed gallbladder as hospital stay and pain are minimal.
