Минералогические исследования в пещерной системе Снежная-Меженного-Иллюзия (Западный Кавказ, Бзыбский хребет): предварительные результаты и направления дальнейших работ

В статье приводятся сведения о минеральном составе водных хемогенных и водных механических отложений в пещерной системе Снежная-Меженного-Иллюзия. В состав водных хемогенных отложений входят Mg- и Sr-содержащий кальцит, арагонит, гипс, гидромагнезит, целестин, стронцианит, доломит, гетит, рутил и циркон. Водные механические отложения сложены преимущественно доломитом, кварцем и кальцитом. В схожих по морфологии и микроклимату частях пещерной системы наблюдаются одинаковые вторичные минералы.У статті наводяться відомості про мінеральний склад водних хемогенних і водних механічних відкладень в печерній системі Сніжна-Меженого-Ілюзія. До складу водних хемогенних відкладень входять кальцит, який містить Mg і Sr, арагоніт, гіпс, гідромагнезіт, целестин, стронціаніт, доломіт, гетит, рутил і циркон. Водні механічні відкладення складені переважно доломітом, кварцом і кальцитом. У схожих за морфологєю та мікрокліматом частинах печерної системи спостерігаються однакові вторинні мінерали.The article presents the preliminary characteristic of the mineral composition of chemogenic formations and clastic deposits of Snezhnaya-Mezhennogo-Illusia cave system. Chemogenic formations are composed by Mg- and Sr-calcite, aragonite, gypsum and hydromagnesite, celestite, strontianite, dolomite, goethite, rutile and zircon. Clastic sediments are composed mainly by dolomite, quartz and calcite. Same secondary minerals are observed in those parts of the cave system that have similar morphology and microclimate

Vaginal prolapse repair with or without a midurethral sling in women with genital prolapse and occult stress urinary incontinence: a randomized trial

We compared pelvic organ prolapse (POP) repair with and without midurethral sling (MUS) in women with occult stress urinary incontinence (SUI). This was a randomized trial conducted by a consortium of 13 teaching hospitals assessing a parallel cohort of continent women with symptomatic stage II or greater POP. Women with occult SUI were randomly assigned to vaginal prolapse repair with or without MUS. Women without occult SUI received POP surgery. Main outcomes were the absence of SUI at the 12-month follow-up based on the Urogenital Distress Inventory and the need for additional treatment for SUI. We evaluated 231 women, of whom 91 randomized as follows: 43 to POP surgery with and 47 without MUS. A greater number of women in the MUS group reported absence of SUI [86 % vs. 48 %; relative risk (RR) 1.79; 95 % confidence interval (CI) 1.29-2.48]. No women in the MUS group received additional treatment for postoperative SUI; six (13 %) in the control group had a secondary MUS. Women with occult SUI reported more urinary symptoms after POP surgery and more often underwent treatment for postoperative SUI than women without occult SUI. Women with occult SUI had a higher risk of reporting SUI after POP surgery compared with women without occult SUI. Adding a MUS to POP surgery reduced the risk of postoperative SUI and the need for its treatment in women with occult SUI. Of women with occult SUI undergoing POP-only surgery, 13 % needed additional MUS. We found no differences in global impression of improvement and quality of lif
