ABSTRACT
OBJECTIVE: The aim of this systematic review is to summarize the data obtained from randomized controlled trials looking at new pharmacologic treatments for endometriosis published over the last decade with a focus on hormonal therapeutic options for endometriosis-associated pelvic pain (EAPP), excluding studies focusing on fertility. METHODS: We identified relevant original studies in the English language through a search of the MEDLINE, Scopus, and EMBASE (2012 to present) databases using the appropriate MeSH terms and applying the article type filter 'randomized controlled trials'. A total of 219 records were found during the electronic search. After a detailed evaluation and review of the manuscripts, 11 primary articles met the inclusion criteria. A systematic review of the data was conducted. RESULTS: This review included several emerging drug therapies for EAPP. Randomized control trials showed promising results with several oral gonadotropin-releasing hormone antagonists (elagolix, relugolix, ASP1707, linzagolix). However, studies of other hormonal agents such as aromatase inhibitors and selective progesterone receptor modulators have not yielded significant or new advantages. Selective estrogen receptor modulators have not been represented in randomized control trials and have failed to demonstrate clinical efficacy. CONCLUSION: Although numerous novel agents are being investigated for the treatment of endometriosis, there is still no significant progress in the development of curative rather than suppressive drugs. Therefore, further efforts are needed to develop an effective and hopefully curative treatment for this chronic, costly, and overwhelming disease.

Bromide in water can form undesirable by-products such as bromate when treated by ozonation during drinking water production. The maximum contaminant level (MCL) for bromate is 10 µg/L in most countries because it is suspected of being carcinogenic. In this paper, the geographical distribution of bromide concentration in Croatian groundwater is presented covering the Pannonian basin and the Dinarides (Adriatic Sea). Groundwater in Croatian wellfields predominantly has a bromide content of less than 50 µg/L and thus belongs to the group with low potential for bromate formation. Waters with higher bromide concentrations were found mainly in the coastal regions of Croatia, probably due to seawater intrusion. In addition, bromide concentration showed a positive correlation of 0.6 with conductivity, chloride, and sodium. In addition, the potential of 123 groundwaters analyzed in this study to form bromate when treated with ozone was evaluated using models available in the literature. Analysis of water from Croatian wellfields indicated that the potential for bromate formation above the MCL during ozonation was relatively low. The models used from the literature predicted quite different values of bromate concentration when applied to the same water, with some values exceeding those theoretically possible. Selected models may be useful as a general warning of possible bromate formation.

Oomycete pathogens in freshwaters, such as Saprolegnia parasitica and Aphanomyces astaci, are responsible for fish/crayfish population declines in the wild and disease outbreaks in aquaculture. Although the formation of infectious zoospores in the laboratory can be triggered by washing their mycelium with natural water samples, the physico-chemical properties of the water that might promote sporulation are still unexplored. We washed the mycelia of A. astaci and S. parasitica with a range of natural water samples and observed differences in sporulation efficiency. The results of Partial Least Squares Regression (PLS-R) multivariate analysis showed that SAC (spectral absorption coefficient measured at 254 nm), DOC (dissolved organic carbon), ammonium-N and fluoride had the strongest positive effect on sporulation of S. parasitica, while sporulation of A. astaci was not significantly correlated with any of the analyzed parameters. In agreement with this, the addition of environmentally relevant concentrations of humic acid, an important contributor to SAC and DOC, to the water induced sporulation of S. parasitica but not of A. astaci. Overall, our results point to the differences in ecological requirements of these pathogens, but also present a starting point for optimizing laboratory protocols for the induction of sporulation.
ABSTRACT
The aim of this study was to determine the efficacy and operative complications of the suprapubic arc (SPARC) procedure in stress incontinent women with and without previous anti-incontinence surgery. One-hundred and twenty-one patients with stress urinary incontinence (SUI) were treated with SPARC for correction of urethral hypermobility (N = 65) and intrinsic sphincter deficiency (N = 56) between August 2002 and February 2007. The long-term surgical results, operative complications (bladder injury, retropubic hematoma, de novo urgency and urinary infection) and patients' satisfaction were assessed. The overall complication rate was 9.9% (12/121). The perioperative complication rate was 1.7% including 2 urinary bladder injuries. Significant difference in the overall complications rate was detected between women with and without previous surgery (23/45, 51.1% vs. 6/108, 5.5%, chi2 = 49.89, P < 0.001). The overall postoperative complication rate was 8.3% (10/121) including 4 de novo urgencies, 4 urinary infections and 2 retropubic hematomas. There were 3 patients with postoperative urinary retention managed conservatively, without voiding difficulties on control visits. The objective cure rate after the follow-up was 86.8% (105/121). In patients with SUI and without preceding vaginal operations SPARC is a good method with low incidence of perioperative complications, promising long-term results and high patient satisfaction.
