    A reappraisal of nitrate inhibition of nitrogenase in A317, a nitrate reductase-deficient mutant of pea (Pisum sativum) (1992)

    Notes: Symbiotic plants of Pisum sativum L. cv. Juneau and its nitrate reductase-(EC 1. 6. 6. 1)-deficient mutant, A317, were exposed to nitrate for up to 8 days and assessed for nitrate assimilation, nitrogenase activity and nodule carbohydrate status. The mutant, A317, was not impaired in its ability to absorb nitrate over up to 8 days, but was leakier with respect to nitrate reduction ability than previously realized, as 63% of the nitrate absorbed by the plant over 8 days was assimilated (in contrast to 93% in the wild type). After 2 days exposure to 5 mM nitrate, nitrogenase (EC 1.18.2.1) activity was less affected in A317 (84% of initial) than in Juneau (46% of initial): nodule starch reserves were less depleted in A317 (70% of initial) than in Juneau (26% of initial). It was concluded that nitrate reduction is a major cause of nitrate inhibition of nodule activity, and that its effect may be mediated through a decrease in the availability of carbohydrate to the nodules. Longer term (〉 4 day) exposure of A317 plants to nitrate resulted in accumulation of nitrate in plant tissues, an associated necrosis of shoot tissue, a marked decrease in nodule starch content and a severe inhibition of nodule activity. This consideration of the effect of the duration of exposure to nitrate is used to resolve a discrepancy between previous reports on the sensitivity to nitrate of nitrogenase activity in nitrate reductase-deficient mutants of pea.

    Notes: The circadian secretory profiles of serum prolactin, growth hormone and cortisol were measured in two women suffering from severe premenstrual tension syndrome and in two asymptomatic control subjects. Subjects and controls were screened and included after a rigorous selection process. Blood samples were obtained every 30 min over a period of 24 h in each woman both on day 9 (follicular phase) and day 26 (luteal phase) of the menstrual cycle. There was no relationship between the hormonal secretory profiles and the premenstrual tension syndrome.

    Notes: Abstract Background: The purpose of this study was to investigate the possibility of detecting bile duct injuries using laparoscopic intraoperative ultrasound (LIOU). Methods: Fifty bile duct injuries were created using laparoscopic techniques in ten farmer pigs. The lesions created were: (1) partial occlusion, (2) complete occlusion (1 clip), (3) complete occlusion (2 clips), (4) transection between clips, (5) excision between clips. Results: All injuries were easily visualized using LIOU. The relation of clips impinging upon or occluding the bile duct was readily visualized on LIOU in all cases. In some cases it was difficult to distinguish between partial and complete occlusion. It was also difficult to distinguish between transection and excision due to retraction of the severed bile duct. Conclusions: In cases of iatrogenic occlusion of the bile duct involving hemoclips (including transection or excision between clips), LIOU is a potentially useful modality that may allow earlier recognition and repair. Further studies are needed to evaluate the efficacy of LIOU in detection of bile duct injuries that do not involve hemoclips.

    Notes: Abstract Background: A comparison of safety, efficacy, and cost of laparoscopic splenectomy (LS) vs open splenectomy (OS) for idiopathic thrombocytopenic purpura (ITP) was performed. Methods: The records of 49 consecutive patients who underwent splenectomy for ITP (31 LS and 18 OS) at a large metropolitan teaching hospital between 3/91 and 8/95 were reviewed. Morbidity, mortality, hospital stay, operative time, blood loss, time to oral fluid intake, direct costs, and operating room (OR) costs were analyzed. Results: Age, sex, comorbidity, and spleen size were similar in both groups. LS was successful in 94% of patients in whom it was attempted. Operative times showed a learning curve for LS, with average times for the last ten cases (94 ± 35 min) significantly shorter than for the first ten (p= 0.01) and also shorter than for OS (103 ± 45 min). Postsurgical hospital stay was 2.9 ± 1.3 days for LS and 6.9 ± 3.0 days for OS (p 〈 0.001). Patients tolerated an oral diet 1.2 ± 0.5 days after LS and 3.2 + 0.7 days after OS (p 〈 0.001). Direct hospital cost was $5,509 ± 3,636 for LS and $9,031 ± 12,752 for OS. In the LS group, six patients (21%) had accessory spleens identified and removed, compared with two patients (11%) in the OS group. Platelet counts did not respond in two (7%) patients in the LS group, but no accessory spleens were identified by nuclear scan. One major complication occurred in the LS group. There were no cases of splenosis or mortality in either group. Conclusions: LS is a safe and effective treatment for ITP, with significantly shorter postoperative hospital stay than OS.

    Notes: Abstract Background: An effort was made to determine whether a policy of routine cholangiography affects the incidence, morbidity, and cost of bile duct injuries. Methods: A retrospective review of consecutive 3,242 laparoscopic cholecystectomies was performed. Most patients had routine intraoperative cholangiography. Results: There were 12 bile duct injuries (0.37%). All injuries were Bismuth levels 1 and 2. Eleven of 12 injuries were recognized intraoperatively. Ten were repaired primarily and one required hepaticojejunostomy. All repairs were successful. Average hospital charges were $26,669. One of 12 patients had delayed recognition of a bile duct injury and underwent primary repair over a T-tube on postoperative day 7. Hospital charges were $43,957. Conclusion: Routine cholangiography did not appear to decrease the absolute incidence of bile duct injuries compared to previously published reports. Injury severity, morbidity, late sequelae, and costs were reduced by a policy of routine cholangiography.

    Notes: Summary Balloon dilatation of the sphincter of Oddi has been performed via a laparoscopic transcystic duct technique. Small common duct stones and stone debris have been successfully lavaged into the duodenum in 17 of 20 cases (85%) by this method. Postoperative hyperamylasemia was noted in four patients. Mild clinical pancreatitis was observed in three patients (15%). Further evaluation of this technique as an adjunct to laparoscopic common bile duct stone extraction is warranted.

    Notes: Abstract One thousand seventy-one consecutive laparoscopic cholecystectomies were performed. Routine cholangiography was employed with a 99% success rate. One hundred thirty patients were found to have common duct stones (CBDS). In 48 (37%) patients they were unsuspected. One hundred eleven patients underwent attempted trans-cystic-duct extraction techniques (TCD-CBDE). One hundred three (93%) were successful. The following techniques were employed: 101—biliary endoscopy, 23—ampullary balloon dilation, 2—fluoroscopic basket retrieval. The average operative time was 136 min. The average postsurgical stay was 3.7 days. There were 19 (17%) complications—6 (5%) major. There were 4 retained stones (2 intentional) and 1 death. Patients over 65 years of age had more complications and patients with unsuspected CBDS under 65 years of age had the fewest. TCD-CBDE is a safe, effective way to extract common duct calculi. Endoscopy and basket stone retrieval was the primary technique employed.

    One hundred consecutive laparoscopic cholangiograms (1996)
    Springer

    Topics: Medicine
    Notes: Abstract Background: In 100 consecutive patients who underwent laparoscopic cholecystectomy, the feasibility, reliability, and cost of routine laparoscopic cholangiography were prospectively studied. Methods: Fluoroscopic cholangiograms with multiple exposures were successfully completed in all patients in an average time of 6.9 min. Results: Twenty-one percent were abnormal, and 15 common duct stones and 6 significant anatomic anomalies detected. Thirteen out of 15 patients with common duct stones had preoperative suspicion of common duct stones. Two out of 15 were completely unsuspected. The average cost of cholangiography was $768, and there were no complications related to the procedure. There were no false interpretations. Conclusions: When compared with selective preoperative endoscopic retrograde cholangiopancreatography (ERCP), routine laparoscopic cholangiography is safer, more accurate, and less costly, and may have the added benefit of potentially reducing iatrogenic injuries in patients with anatomic variations. Routine laparoscopic cholangiography should be considered by all surgeons.
