Pelvic pain in endometriosis: painkillers or sport to alleviate symptoms?

To assess potential individual factors influencing quality of life and pain scores of patients suffering from histologically confirmed endometriosis. Study using a questionnaire among patients of reproductive age undergoing laparoscopy with a presumed diagnosis of endometriosis. Details of fertility, previous treatments and quality of life, sexual activity, as well as linear pain scores for several symptoms, were recorded. Details of intraoperative findings were also collected and only those data were used where endometriosis was intraoperatively and histologically proven. A questionnaire before surgery gathered information from women on the following groups of variables: age, marital status, education, reproductive and medical history including previous pregnancies and parity, knowledge of accompanying pelvic disorders, regular sport activity, as well as general quality of life estimates including self-image. Pelvic pain was scored using a visual analogue scale. Data were statistically evaluated. Eighty-one patients complaining about persistent pelvic pain were later intraoperatively and histologically proven to have endometriosis. Thirty-one of them (38.2%) reported regular sport as part of their daily life schedule while 50 of them (61.8%) performed no physical activity at all. Fourteen patients among regular exercisers and 33 patients among those without physical activity reported the effectiveness of painkillers for pelvic pain, corresponding to 45.1% and 66% of these subgroups, respectively (difference statistically significant, p<0.05). Based on our results, we can conclude, that taking painkillers might be less effective among endometriosis patients performing regular daily sport activities, and, thus it might impose them to an unnecessary burden of possible side-effects.

Annual fluctuation in amplitudes of daily variations of electrical signals measured in the trunk of a standing tree.

Electrical potential differences between electrodes inserted in eight selected sites of the trunk of a Turkey oak (Quercus cerris) and the ground have been recorded continuously since November 1997. The mean amplitudes of daily electric variations were determined for time intervals when the meteorological and atmospheric electricity conditions were undisturbed. It was found that the mean daily amplitudes show a characteristic annual fluctuation. Both in 1998 and in 1999 two peaks were observed: the first maximum appears suddenly about the end of March, and the second one was seen in late June, July. Between November and March the mean amplitudes were smaller by about one order of magnitude.
