An examination of past theorizing and research suggests that the role of humor in interpersonal interaction needs reconsideration. It was hypothesized that one of the functions of humor is its role in providing a means of communication between individuals. Sixty male undergraduate subjects were given cartoons to rate by an attractive female experimenter. It was hypothesized that where possible, male subjects would use appreciation of sexual humor as a means of communicating sexual interest in the female experimenter. Since motivation arousal has also been reported to affect humor preferences, a 2 X 2 design was employed to permit independent evaluation of the arousal variable and the communication variable. Both independent variables were found to be effective, with communication the more potent one. Further implications of the social communication hypothesis are suggested.

Introduction:We looked at the reasons why fluorescent cholangiography (FC) should be used routinely in laparoscopic cholecystectomy (LC). Method: A single dose of 0.05 mg/kg of Indocyanin Green (ICG) was administered intravenously one hour prior to the surgery to perform fluorescent cholangiograhy. Results: FC could be performed in all 45 (100%) patients whereas intra-operative cholangiography (IOC) could be performed in 42 out of 45 (93%) patients (p < 0.078). Individual median cost of performing FC was cheaper than IOC (13.97 ± 4.3 vs 778.43 ± 0.4 US dollars per patient, p = 0.0001). The mean operative time was 64.95 ± 17.43 minutes. FC was faster than IOC (0.71 ± 0.26 vs 7.15 ± 3.76 minutes, p < 0.0001). The cystic duct was identified by FC in 44 out of 45 patients (97.77 %). The residents were able to identify the extrahepatic structures in all 45 cases (100%) with FC. No complications were detected related to surgery and the use of FC. Learning curve was not necessary to identify structures using FC. X-ray leads were only used for IOC. FC could be performed by all residents at different level of training in 100% of the cases. Smooth dissection, transection and resection could be safely performed in 45 cases (100%). Conclusion: Fluorescent cholangiography seems to be feasible, cheap, expeditious, useful, an effective teaching tool, safe, no learning curve is necessary, does not require x-ray and easy to perform. It can be used for real time surgery to delineate the extrahepatic biliary structures.Background: Objective of this study is to compare rates of pancreatic fistulas and complications following the Whipple operation between pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG).Methods: 98 patients undergoing Whipple resection were randomized to either PG (48) or PJ (50) reconstruction. T-test and Chi-square tests were used for intention to treat data analysis. Logistic regression was used to measure the influence of surgical technique, preoperative ASA score and soft pancreatic gland on overall complications, severe post operative complications and overall fistula rates. Results: The rate of pancreatic fistula formation was 18% (Grade A = 6%, B = 10%, C = 2%) in the PJ arm and 25% (Grade A = 8%, B = 13%, C = 4%) in the PG arm, p = 0.399. The rate of postoperative complications was 48% (Clavien 1 = 14%, 2 = 36%, 3 = 10%, 4 = 0%, 5 = 2%) in the PJ and 58% (Clavien 1 = 21%, 2 = 38%, 3 = 25%, 4 = 6%, 5 = 4%) in the PG arm, p = 0.306. There was a significant difference in severe complications (Clavien 3-5) with 12% in the PJ and 31% in the PG arm, p = 0.02. In the multivariate analysis randomization (together with ASA) was only predictive of severe complications (OR 0.10, p < 0.005 for randomization to PJ reconstruction; OR 11.58, p < 0.05 for ASA 2 and OR 30.89, p < 0.05 for ASA 3 compared to ASA 1). Conclusion: Results of the study suggest that while there are no overall differences in rates of pancreatic leak/fistula and overall complications between PG and PJ arms, pancreaticogastrostomy is associ...
