This article reviews theory and research regarding the physiology, situational and dispositional antecedents, behavioral concomitants, and interpersonal consequences of social blushing and offers a new theoretical account of blushing. This model posits that people blush when they experience undesired social attention. Puzzling questions involving blushing in solitude, the phenomenology of blushing, types of blushing, and blushing in dark-skinned people are discussed.

Extraperitoneal colorectal anastomoses were constructed in dogs by four methods: one layer of sutures (N = 10), two layers of sutures (N = 10), EEA staples (N = 10), and SPTU staples (N = 10). Dehiscence occurred in eight sutured and one stapled anastomosis (P less than 0.05). The four leaks following two layer sutured anastomoses caused three deaths, whereas all four leaks following one-layer sutured anastomoses were only detected radiologically (P less than 0.02). In the stapled group, the single leak followed EEA anastomosis and was fatal. Anastomotic narrowing was greater in sutured than stapled groups (P less than 0.05). Two layers of sutures produced gross narrowing compared with one layer (P less than 0.002). Two rows of staples (EEA) produced more narrowing than one row (SPTU) (P less than 0.01). Mean hydroxyproline concentrations and bursting pressures on the seventh postoperative day were higher in stapled than sutured anastomoses (P less than 0.05). Submucosal alignment, mucosal continuity, tissue viability, and stage of healing were all inferior for two-layer sutured anastomoses, reaching statistical significance for tissue viability (P less than 0.05). Stapled anastomoses were completed significantly faster (32.6 +/- 7.3 minutes) than sutured (54.1 +/- 8.4 minutes) (P less than 0.01). This experimental study has demonstrated that stapling is a fast and reliable method of colorectal anastomosis with a low complication rate. The shortcomings of the standard two-layer sutured anastomosis are discussed.
In an experimental study the function of the 3-loop (Parks) pelvic ileal reservoir was compared with that of the 2-loop (Utsunomiya) reservoir. Both types achieved satisfactory degrees of continence and evacuation when tested in the defunctioned state. Following restoration of intestinal continuity, the stools of dogs with 3-loop pouches were usually liquid (69 percent) compared to the more formed stools (72 percent) in the 2-loop group, P less than 0.001. At postmortem the reservoirs of the 3-loop group were found to have undergone much greater dilatation (P less than 0.05). These findings suggest that construction of the 3-loop (Parks) pelvic reservoir may lead to retention with overflow if catheterization is not used. It is not clear whether the superior function of the 2-loop pouch is attributable to better motor function or the absence of an efferent limb which allows it to be placed deep in the pelvis.

One hundred and thirty seven previously untreated out-patients with first and second degree haemorrhoids were allocated at random to treatment by infrared coagulation (n=66) or rubber band ligation (n=71). Complete follow up was obtained in 122 patients (60 who had undergone infrared coagulation (group 1), and 62 rubber band ligation (group 2)) at periods from three months to one year after completion of treatment. Infrared coagulation produced a satisfactory outcome in 51 patients (85%): 34 were rendered asymptomatic and 17 improved. Rubber band ligation produced a satisfactory outcome in 57 patients (92%): 33 were rendered asymptomatic and 24 improved. Both methods were equally effective in first and second degree haemorrhoids. The incidence of side effects, particularly discomfort, during and after treatment was significantly higher in those treated by rubber band ligation (p less than 0.001). This appeared to be an appreciable deterrent to future patient compliance. The number of patients losing more than 24 hours from work was higher after rubber band ligation than after infrared coagulation. The number of treatments necessary to cure symptoms did not differ significantly between the two methods. Infrared coagulation was significantly faster than rubber band ligation (p less than 0.001). Infrared coagulation is a simple, fast, and effective outpatient method for the treatment of first and second degree haemorrhoids with fewer troublesome side effects and higher patient acceptability than rubber band ligation.

A novel metabolite, alpha-phenyl-gamma-butyrolactone, isolated from the urine of a glutethimide overdose victim, was synthesized and tested for biological activity in mice. Interperitoneal injections of this lactone caused severe toxicity at moderate dose levels. These results point to another metabolite of glutethimide contributing toxicity to patients severely intoxicated by the parent drug. An improved synthesis as well as complete spectral data of this lactone are also presented.
A new metabolite of glutethimide has been isolated and identified as a methylated catechol. Gas chromatographic parameters as well as mass spectral data are presented which clearly reveal this metabolite to be present in enzymatically hydrolyzed urine of patients severely intoxicated by the parent drug.
