despite the excellent results published on circular stapled mucosectomy ( csm ) , there is still some concern about the application of pph-@ in the advanced haemorrhoidal disease , where a major prolapse may lead to insufficient resection and ensuing early recurrence . this study is aimed at comparing the outcomes after single purse-string csm versus double purse-string csm . a prospective randomised clinical trial of single versus double purse-string csm for grade iii-iv symptomatic haemorrhoids was used . one hundred consecutive patients were randomised to single ( group @ , n = @ ) versus double purse-string csm ( group @ , n = @ ) . the mean age was @ years , with a predominance of males ( @ vs. @ ) . haemorrhoids were classified as grade iii in @ % and grade iv in @ % of the patients . mean follow-up was @ months . demographic and clinical features showed no differences between the two groups . the size of the resected doughnut was greater in group @ ( @ vs. @ cm ; p < @ ) , as was the distance of the suture from the dentate line ( @ vs. @ cm ; p < @ ) . early postoperative pain was significantly less in group @ ( linear analogue scale from @ to @ ) , @ vs. @ ( p < @ ) . postoperative haemorrhage was absent or minimal in @ % of patients . three patients from group @ reported persistent pain that was resolved within the first few postoperative months . there were two recurrences in group @ . double purse-string csm resects a greater doughnut , increases the distance of the staple suture from the dentate line and reduces early postoperative pain in comparison to single purse-string csm . larger series are necessary to assert whether recurrence is lower .

the efficacy of treatment in hemianopic patients to restore missing vision is controversial . so far , successful techniques require laborious stimulus presentation or restrict improvements to selected visual field areas . due to the large number of brain-damaged patients suffering from visual field defects , there is a need for an efficient automated treatment of the total visual field . a customized treatment was developed for the reaction perimeter , permitting a time-saving adaptive-stimulus presentation under conditions of maximum attention . twenty hemianopic patients , without visual neglect , were treated twice weekly for an average of @ months starting @ months after the insult . each treatment session averaged @ min in duration . in @ out of @ patients a significant and stable increase of the visual field size ( average @ degrees + / - @ ) was observed as well as improvement of the detection rate in the defective visual field ( average @ % + / - @ ) . a two-factor cluster analysis demonstrated that binocular treatment was in general more effective in augmenting the visual detection rate than monocular . four out of five patients with a visual field increase larger than @ degrees suffered from hemorrhage , whereas all seven patients with an increase of @ degrees or less suffered from infarction . most patients reported that visual field restoration correlated with improvement of visual-related activities of daily living . rehabilitation treatment with the lubeck reaction perimeter is a new and efficient method to restore part of the visual field in hemianopia . since successful transfer of treatment effects to the occluded eye is achieved under monocular treatment conditions , it is hypothesized that the damaged visual cortex itself is the structure in which recovery takes place .

this study aimed to verify whether techniques of yoga with and without the addition of tui na might improve pain and the negative impact of fibromyalgia ( fms ) on patients ' daily life . forty ( @ ) fms women were randomized into two groups , relaxing yoga ( ry ) and relaxing yoga plus touch ( ryt ) , for eight weekly sessions of stretching , breathing , and relaxing yogic techniques . ryt patients were further submitted to manipulative techniques of tui na . outcome measures comprised the fibromyalgia impact questionnaire ( fiq ) , pain threshold at the @ fms tender points , and a verbal graduation of pain assessed before treatment and on the followup . the visual analog scale ( vas ) for pain was assessed before and after each session and on the follow-up . seventeen ( @ ) ryt and @ ry patients completed the study . both ry and ryt groups showed improvement in the fiq and vas scores , which decreased on all sessions . the ryt group showed lower vas and verbal scores for pain on the eighth session , but this difference was not maintained on the follow-up . conversely , ry vas and verbal scores were significantly lower just on the follow-up . these study results showed that yogic techniques are valid therapeutic methods for fms . touch addition yielded greater improvement during the treatment . over time , however , ry patients reported less pain than ryt . these results suggest that a passive therapy may possibly decrease control over fms symptoms .

the use of oral contraceptives is associated with an increased risk of developing hypertension but the mechanisms of this hypertensive effect are not completely defined . the purpose of the present study was to assess prospectively the systemic and renal hemodynamic and tubular responses to salt in women taking oral contraceptives . twenty seven young healthy normotensive women taking oral contraceptives containing monophasic combination of @ microg ethynilestradiol and @ microg desogestrel for > @ months were enrolled . all women were assigned at random to receive a low ( @ mmol/day ) or a high ( @ mmol/day ) sodium diet for @ week on two consecutive menstrual cycles during the active oral contraceptive phase . at the end of each diet period , @-hour ambulatory blood pressure , renal hemodynamics , sodium handling , and hormonal profile were measured . the blood pressure response to salt on oral contraceptives was characterized by a salt-resistant pattern with a normal circadian rhythm . salt loading results in an increase in glomerular filtration rate ( gfr ) ( p < @ vs. low salt ) , with no change in the renal plasma flow , thus leading to an increase in the filtration fraction ( p < @ ) . at the tubular level , women on oral contraceptives responded to a low salt intake with a marked increased in proximal sodium conservation ( p < @ vs. high salt ) and with an almost complete reabsorption of sodium reaching the distal tubule . after sodium loading , both the proximal and the distal reabsorption of sodium decreased significantly ( p < @ ) . the use of oral contraceptives is not associated with an increased blood pressure response to salt in young normotensive women . however , oral contraceptives affect the renal hemodynamic response to salt , a high salt intake leading to an increase in gfr and filtration fraction . this effect is possibly mediated by the estrogen-induced activation of the renin-angiotensin system . oral contraceptives also appear to increase the tubular responsiveness to changes in sodium intake . taken together , these data point out evidence that synthetic sex steroids have a significant impact on renal function in women . the renal effects of oral contraceptives should be taken into account when managing young women with renal diseases .
