Imiquimod for treatment of vulvar and vaginal intraepithelial neoplasia.

We searched PubMed, Scopus, Web of Science, LILACS, EMBASE, and Cochrane Library databases to assess the effectiveness and safety of 5% imiquimod cream in the treatment of vulvar and vaginal intraepithelial neoplasia. From the results of the 17 relevant articles identified (1 reported on a randomized controlled trial, 10 reported on case series, and 6 were case reports), 26% to 100% of patients had complete regression, 0% to 60% had partial regression, and 0% to 37% experienced recurrence. The most common adverse events were local burning and soreness, but not severe enough for patients to discontinue treatment. From these reports imiquimod treatment leads to complete response in a considerable percentage of patients, and those who experience partial response will require less extensive excision. Treating vulvar and vaginal intraepithelial neoplasia with 5% imiquimod cream therefore appears to be promising.     

Does the use of probiotics/synbiotics prevent postoperative infections in patients undergoing abdominal surgery? A meta-analysis of randomized controlled trials

Background  Advances in surgery have considerably lowered postoperative morbidity. However, infection remains a considerable morbidity factor. The aim of this review is to identify the potential benefit(s) of the perioperative administration of probiotics/synbiotics to patients undergoing abdominal surgery. Methods  We searched PubMed, Scopus, Web of Science, and Cochrane library to identify randomized controlled trials (RCTs) that studied the perioperative administration of probiotics/synbiotics to patients undergoing abdominal surgery. Results  Nine RCTs studying 733 patients were included in our review. The incidence of postoperative pneumonia, cholangitis, and any infections as well as the duration of postoperative hospital stay and length of antibiotic therapy were lower among patients receiving probiotics than in the control group [six RCTs, 355 patients, odds ratio (OR) 0.24, 95% confidence interval (CI) 0.09–0.68; three RCTs, 209 patients, OR 0.18, 95% CI 0.05–0.57; seven RCTs, 514 patients, OR 0.26, 95% CI 0.12–0.55; five RCTs, 313 patients, OR −2.70, 95% CI −5.15 to −0.25; four RCTs, 250 patients, OR  −4.01, 95% CI −5.11 to −2.92, respectively], while the incidence of postoperative wound infection, urinary tract infection, intra-abdominal abscess, and mortality was not different between patients of the compared groups (six RCTs, 355 patients, OR 0.52, 95% CI 0.23–1.18; five RCTs, 313 patients, OR 0.44, 95% CI 0.04–5.54; four RCTs, 226 patients, OR 0.44, 95% CI  0.12–1.59; nine RCTs, 685 patients, OR 0.98, 95% CI 0.29–3.29, respectively). Conclusion  The use of probiotics/synbiotics may reduce postoperative infections after abdominal surgery. This is a promising infection-preventive measure that may decrease morbidity, length of antibiotic therapy, duration of hospital stay, and pressure for emergence of antimicrobial resistance. However, the results of this meta-analysis should be interpreted with caution due to the significant heterogeneity of the studies included.     

Assessment of overactive bladder symptoms among women with successful pessary placement

Introduction and hypothesis

The causal association between pelvic organ prolapse (POP) and overactive bladder (OAB) symptoms is supported by several theories. The aim of this study is to assess any changes in OAB symptoms among women with POP and OAB after successful pessary placement.

Methods

During the study period, all women with symptomatic POP stage II or greater and OAB symptoms were offered the solution of either a ring or a Gellhorn pessary. All patients were asked to complete a 3-day micturition/incontinence diary. Objective evaluation endpoints at baseline and at 6 weeks included: change in the mean number of micturitions/24 h, change in the mean volume voided per micturition/24 h, and change in the number of urinary incontinence episodes. Subjective evaluation of the urgency, frequency, and nocturia symptoms was carried out using the score change of the questions 3, 5, and 2 of the International Consultation on Incontinence Questionnaire for Evaluating Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) respectively.

Results

Seventy-four women were included in the study. A statistically significant decrease (?28.3%; p < 0.001) of the mean number of micturitions/24 h with a significant increase (37%; p < 0.001) in the mean voided volume per micturition/24 h was observed. The total urine volume/24 h remained unchanged. The number of urinary incontinence episodes was significantly increased 6 weeks after pessary placement (p < 0.001). De novo stress urinary incontinence (SUI) was reported by 16.7% of the initially stress continent women.

Conclusions

Women with coexisting POP and OAB symptoms may experience a significant improvement in micturition frequency and in urgency and frequency symptoms after successful pessary fitting.

     

Microablative fractional CO<Subscript>2</Subscript> laser for the genitourinary syndrome of menopause: power of 30 or 40 W?

This retrospective case-control study aimed to compare 30 versus 40 W power of CO₂ laser for the therapy of genitourinary syndrome of menopause (GSM). Postmenopausal women with severe intensity of dyspareunia and dryness were eligible to be included in this study. Primary outcomes were dyspareunia and dryness. Secondary outcomes were itching/burning, dysuria, frequency and urgency, Female Sexual Function Index (FSFI), vaginal maturation value (VMV), and Vaginal Health Index Score (VHIS). One laser therapy was applied every month for 3 months. Outcomes were evaluated at baseline and 1 month following the 3rd therapy. Fifty (25 per group) women were included in this study. In the 30-W group, mean improvement of dyspareunia, dryness, itching/burning, FSFI, VMV, and VHIS was 6.1 ± 1.7, 6.0 ± 1.9, 5.9 ± 2.0, 16.6 ± 6.7, 29.9 ± 13.0, and 11.0 ± 2.9, respectively (within group comparisons all p < 0.001). In the 40-W group, mean improvement of dyspareunia, dryness, itching/burning, FSFI, VMV, and VHIS was 6.1 ± 1.7, 6.5 ± 2.0, 5.2 ± 2.5, 14.8 ± 7.1, 25.0 ± 13.4, and 10.5 ± 4.1, respectively (within-group comparisons, all p ≤ 0.001). Comparison between 30 and 40 W revealed that mean improvement or presence of all GSM symptoms and clinical signs was not statistically significant different. CO₂ laser therapy may improve GSM symptoms and clinical signs. This improvement did not seem to associate to power of 30 or 40 W.     

First report of Cryptococcus neoformans var. gattii serotype B from Greece.

A plethora of cases of Cryptococcus neoformans infections have been recorded worldwide in immunocompromised individuals. The number of such cases showed a steady rise before 1981 and increased dramatically thereafter due to the AIDS epidemic. A similar pattern has been seen in Greece but, so far, infections appear to have been caused by C. neoformans var. neoformans. This paper describes for the first time two culture-proven C. n. var. gattii serotype B infections in Greece, one in an AIDS patient and one in a patient with systemic lupus erythematosus.     

Pre‐ and postoperative magnetic resonance imaging (MRI) findings in patients treated with laparoscopic sacrocolpopexy. Is it a safe procedure for all patients?

Introduction

Laparoscopic sacrocolpopexy (LSCP) is a reference operation for apical compartment prolapse repair. Aim of this study is to describe the early and midterm postoperative MRI findings of the lumbosacral region (LSR) in patients undergoing LSCP and to detect any imaging changes that the presence of the mesh may cause on patients with preexisting degenerative disease of the LSR.

Methods

Patients with POP‐Q grade III and IV uterovaginal or vaginal vault prolapse who were considered eligible for LSCP were invited to participate. An MRI of the LSR was performed preoperatively and then 3 and 12 months postoperatively. Patients with vaginal vault prolapse underwent LSCP, while women with uterovaginal prolapse were treated with the vaginally assisted laparoscopic sacrocolpopexy (VALS).

Results

A total of 30 patients were included in the study; 18 (60%) underwent LSCP and 12 (40%) VALS. On preoperative MRIs, 83.3% (25/30) of patients had degenerative changes and 70% (21/30) reported having low back pain (LBP). Postoperative MRIs did not reveal any imaging changes compared to the preoperative MRI findings both for patients with or without preexisting degenerative abnormalities of the LSR. No significant changes in the LBP score were observed postoperatively.

Conclusions

Any bone marrow or soft‐tissue changes at MRIs of the LSR early after the insertion of a synthetic mesh, does not constitute an expected postoperative finding and should raise the suspicion of an ongoing inflammatory or infectious spinal process (spondylodiscitis). Additionally, LSCP seems to be a safe surgical approach for women with preexisting degenerative disease of the LSR.     

Hyaluronic Acid: An Effective Alternative Treatment of Interstitial Cystitis,Recurrent Urinary Tract Infections,and Hemorrhagic Cystitis?

OBJECTIVES: Hyaluronic acid is a protective barrier of the urothelium. A damaged glycosaminoglycan layer may increase the possibility of bacterial adherence and infection. This damage is proposed to be a causative factor in the development of interstitial cystitis, common urinary tract infections, and hemorrhagic cystitis due to posthematopoietic stem cell transplantation. The aim of this article was to review the available data regarding the use of hyaluronic acid as an alternative treatment of the above-mentioned conditions. METHODS: Articles relevant to our review that were archived by September 2006 were retrieved from PubMed. RESULTS: Nine relevant studies were identified and evaluated. Hyaluronic acid was administered intravesically at a dose of 40 mg every week for 4-6 wk; patients with noted improvement received two additional monthly doses. Short-term responses of patients with interstitial cystitis, hemorrhagic cystitis, and recurrent urinary tract infections were 30-73% (7 studies), 71% (1 study), and 100% (1 study), respectively. The treatment was well tolerated except for occasional development of bacterial cystitis. The cost of each intravesical installation of hyaluronic acid is 120 UK pounds (excluding the cost of the urinary catheterization). CONCLUSIONS: The available clinical data regarding the effectiveness of hyaluronic acid as a potential treatment of patients with interstitial cystitis, recurrent urinary tract infections, and hemorrhagic cystitis are limited. There is need for randomized controlled trials for further investigation of this important therapeutics question; these clinical trials should be disease-specific, blinded, and controlled, and of a sufficient number of patients. Until such studies are available, intravesical instillation of hyaluronic acid cannot be unquestionably endorsed for use for the aforementioned diseases.     

Single-dose azithromycin versus erythromycin or amoxicillin for Chlamydia trachomatis infection during pregnancy: a meta-analysis of randomised controlled trials

This review aimed to compare data regarding the effectiveness and safety of azithromycin with alternative regimens in the treatment of pregnant women with Chlamydia trachomatis infection. PubMed and Scopus databases were searched to identify relevant randomised controlled trials (RCTs). The main analysis focused on comparison of azithromycin with erythromycin. In a secondary analysis, azithromycin was compared with erythromycin or amoxicillin. Eight RCTs studying 587 pregnant women with microbiologically documented C. trachomatis infection were included in the meta-analysis. Overall, there was no difference between azithromycin and erythromycin regarding treatment success in intention-to-treat patients (pooled odds ratio (OR)=2.66, 95% confidence interval (CI) 0.69-10.29) or in clinically evaluated patients (OR=1.46, 95% CI 0.56-3.78). Furthermore, azithromycin was associated with fewer gastrointestinal adverse events (OR=0.11, 95% CI 0.07-0.18), fewer total adverse events (OR=0.11, 95% CI 0.07-0.18), a smaller proportion of patients who withdrew from the study (OR=0.12, 95% CI 0.04-0.37) and better compliance (OR=23.7, 95% CI 9.34-60.14) than erythromycin. The results of the secondary analysis comparing azithromycin with erythromycin or amoxicillin were similar to those of the main analysis. In conclusion, azithromycin was associated with similar effectiveness but less adverse events compared with erythromycin or amoxicillin in the treatment of pregnant women with C. trachomatis infection.
