Documentation in laparoscopic surgery.
Technological developments have increased tremendously the possibilities for the application of image documentation techniques in gynaecological laparoscopy. Increased quality of optical endoscopes, powerful light sources, highly sensitive photographic films and miniature electronic video cameras have largely removed the barriers to efficient documentation. This equipment is no longer considered to be only for 'hobbyists', but has become an essential part of diagnostic and surgical laparoscopy. Future developments can only increase its applications further.
Sonographic investigation of the uterus during artificial uterine cavity distention.
The improvement of sonographic examination of the uterus during artificial uterine cavity distention was studied in 30 consecutive patients in whom a hysteroscopy was indicated. In 10 of 21 patients with a normal sonographic appearence of the uterus, after filling the uterine cavity with Hyskon, various pathologic conditions became visible. In 5 of 9 patients with abnormal sonographic appearance of the uterus, the procedure enabled a more precise diagnosis concerning localization of abnormal echoes in the uterus. The advantage of this method was clearly demonstrated in cases of central echogenic structures, congenital uterine anomalies, myoma's, synechiae, and corpora aliena.
Indication of increase of the lecithin/sphingomyelin (L/S) ratio in lung fluid of lambs maternally treated with metabolite VIII of Bisolvon.
Metabolite VIII of Bisolvon (Met. VIII) was administered to six pregnant ewes (i.m. daily 5 or 10 mg/kg for 7-9 days). The treatment was started at the 116th/117th or 117th/118th day of gestation and in one case the drug was given to the fetus (i.v. 2 mg/ml/h). Fetal lung fluid obtained from chronically implanted catheters was used for the estimation of the lecithin/sphingomyelin ratio. The maternal treatment with Met. VIII resulted in a significantly increased growth of the L/S ratio compared to the control group (n=4). In three lambs a sharp increase of the L/S ratio was noticed during the last days of Met. VIII treatment. The time gap between first treatment and noticeable effect was 6-8 days. It is postulated that the noticed increase of L/S ratio is the consequence of Met. VIII treatment and very unlikely the result of a release of glucocorticoticoids.
