RESUMO

INTRODUCTION AND HYPOTHESIS: Our aim was to compare the mid-term results of native tissue, biological xenograft and polypropylene mesh surgery for women with vaginal wall prolapse. METHODS: A total of 1348 women undergoing primary transvaginal repair of an anterior and/or posterior prolapse were recruited between January 2010 and August 2013 from 35 UK centres. They were randomised by remote allocation to native tissue surgery, biological xenograft or polypropylene mesh. We performed both 4- and 6-year follow-up using validated patient-reported outcome measures. RESULTS: At 4 and 6 years post-operation, there was no clinically important difference in Pelvic Organ Prolapse Symptom Score for any of the treatments. Using a strict composite outcome to assess functional cure at 6 years, we found no difference in cure among the three types of surgery. Half the women were cured at 6 years but only 10.3 to 12% of women had undergone further surgery for prolapse. However, 8.4% of women in the mesh group had undergone further surgery for mesh complications. There was no difference in the incidence of chronic pain or dyspareunia between groups. CONCLUSIONS: At the mid-term outcome of 6 years, there is no benefit from augmenting primary prolapse repairs with polypropylene mesh inlays or biological xenografts. There was no evidence that polypropylene mesh inlays caused greater pain or dyspareunia than native tissue repairs.

RESUMO

Despite numerous available psoriasis treatments, no "one size fits all" regimen provides complete disease control without side effects, logistical obstacles, and/or expense. Despite increasingly efficacious drugs, only 20-25% of patients treated with biologic therapies achieve completely clear skin (PASI 100) and even fewer achieve this if they have experienced failures of multiple biologics.

RESUMO

BACKGROUND: Current evidence for dexmedetomidine-suspected fever (DSF) is limited. Lack of recognition may lead to costly or potentially harmful interventions for critically ill patients. OBJECTIVE: The primary objective was to characterize escalations of care related to DSF. Secondary objectives were to describe the incidence, severity, and consequences associated with DSF. METHODS: A retrospective review was conducted in critically ill adults who developed fever ≥39°C within 12 h from initiation of dexmedetomidine, with resolution of fever to <39°C within 12 h after discontinuation. The primary outcome was percentage of patients who received an escalation of care due to fever. Secondary outcomes included the percentage of patients who developed a multidrug-resistant organism or Clostridium difficile infection. RESULTS: Eighteen of 3943 patients screened in 4099 encounters met criteria for DSF (0.4%). The majority were white (83.3%), male (66.7%), and underwent cardiac surgery (61.1%). Median (interquartile range [IQR]) time to fever onset and resolution were 5.5 (3.6-7.6) and 1.3 (1.0-2.9) h. Nine patients (50%) underwent infectious workup including antimicrobial initiation (n = 1, 5.6%), broadening of antimicrobials (n = 4, 22.2%), or culture collection (n = 9, 50%). Eleven patients (61.1%) underwent attempted temperature reduction. Twelve patients (66.7%) underwent diagnostic imaging. Incidence of multidrug-resistant organism and C. difficile infection were low (11.1 and 16.7% of fever patients, respectively). CONCLUSION AND RELEVANCE: Incidence of DSF was low and more common in cardiac surgery patients. Unrecognized DSF led to an escalation of care in most patients. Dexmedetomidine exposure should be considered as a potential cause of fever in critically ill adults.

RESUMO

BACKGROUND: Heavy menstrual bleeding affects 25% of women in the UK, many of whom require surgery to treat it. Hysterectomy is effective but has more complications than endometrial ablation, which is less invasive but ultimately leads to hysterectomy in 20% of women. We compared laparoscopic supracervical hysterectomy with endometrial ablation in women seeking surgical treatment for heavy menstrual bleeding. METHODS: In this parallel-group, multicentre, open-label, randomised controlled trial in 31 hospitals in the UK, women younger than 50 years who were referred to a gynaecologist for surgical treatment of heavy menstrual bleeding and who were eligible for endometrial ablation were randomly allocated (1:1) to either laparoscopic supracervical hysterectomy or second generation endometrial ablation. Women were randomly assigned by either an interactive voice response telephone system or an internet-based application with a minimisation algorithm based on centre and age group (<40 years vs ≥40 years). Laparoscopic supracervical hysterectomy involves laparoscopic (keyhole) surgery to remove the upper part of the uterus (the body) containing the endometrium. Endometrial ablation aims to treat heavy menstrual bleeding by destroying the endometrium, which is responsible for heavy periods. The co-primary clinical outcomes were patient satisfaction and condition-specific quality of life, measured with the menorrhagia multi-attribute quality of life scale (MMAS), assessed at 15 months after randomisation. Our analysis was based on the intention-to-treat principle. The trial was registered with the ISRCTN registry, number ISRCTN49013893. FINDINGS: Between May 21, 2014, and March 28, 2017, we enrolled and randomly assigned 660 women (330 in each group). 616 (93%) of 660 women were operated on within the study period, 588 (95%) of whom received the allocated procedure and 28 (5%) of whom had an alternative surgery. At 15 months after randomisation, more women allocated to laparoscopic supracervical hysterectomy were satisfied with their operation compared with those in the endometrial ablation group (270 [97%] of 278 women vs 244 [87%] of 280 women; adjusted percentage difference 9·8, 95% CI 5·1-14·5; adjusted odds ratio [OR] 2·53, 95% CI 1·83-3·48; p<0·0001). Women randomly assigned to laparoscopic supracervical hysterectomy were also more likely to have the best possible MMAS score of 100 than women assigned to endometrial ablation (180 [69%] of 262 women vs 146 [54%] of 268 women; adjusted percentage difference 13·3, 95% CI 3·8-22·8; adjusted OR 1·87, 95% CI 1·31-2·67; p=0·00058). 14 (5%) of 309 women in the laparoscopic supracervical hysterectomy group and 11 (4%) of 307 women in the endometrial ablation group had at least one serious adverse event (adjusted OR 1·30, 95% CI 0·56-3·02; p=0·54). INTERPRETATION: Laparoscopic supracervical hysterectomy is superior to endometrial ablation in terms of clinical effectiveness and has a similar proportion of complications, but takes longer to perform and is associated with a longer recovery.

RESUMO

The American Academy of Dermatology is modernizing its clinical practice guidelines to be more timely and easily interpretable, while decreasing the influence of conflicts of interest in guideline generation. The main changes include the transition from SORT to GRADE methodology and the requirement that nonconflicted members of the guideline work groups remain nonconflicted throughout the entire guidelines process.

RESUMO

BACKGROUND: Previous studies at single academic institutions have identified variations in the prevalence of photodermatoses among racial groups. The purpose of the study was to compare the distribution of photodermatoses between Whites and Blacks at four academic medical centers in the USA. METHODS: A retrospective chart review was performed at four institutions' general dermatology clinics using diagnoses consistent with the International Classification of Disease (ICD), Ninth and Tenth Revisions, codes related to photodermatoses between August 2006 and August 2016. A total of 9736 charts were manually reviewed and classified. Analyses were performed analyzing the frequency of photodermatoses between Whites and Blacks in the pooled data. RESULTS: There were 1,080 patients with photodermatoses identified. Statistically significant differences in the frequency of photodermatoses between Whites and Blacks were identified for polymorphous light eruption (more common in Blacks), photoallergic contact dermatitis, phototoxic drug eruption, phytophotodermatitis, porphyria, and solar urticaria (more common in Whites). The most commonly diagnosed photodermatoses were polymorphous light eruption (total 672), and photodermatitis not otherwise specified (total 189). CONCLUSION: Our study demonstrated significantly higher proportions of polymorphous light eruption in Blacks, and higher proportions of photoallergic contact dermatitis, phototoxic drug eruptions, phytophotodermatitis, porphyrias, and solar urticaria in Whites.

RESUMO

BACKGROUND: The use of transvaginal mesh and biological graft material in prolapse surgery is controversial and has led to a number of enquiries into their safety and efficacy. Existing trials of these augmentations are individually too small to be conclusive. We aimed to compare the outcomes of prolapse repair involving either synthetic mesh inlays or biological grafts against standard repair in women. METHODS: We did two pragmatic, parallel-group, multicentre, randomised controlled trials for our study (PROSPECT [PROlapse Surgery: Pragmatic Evaluation and randomised Controlled Trials]) in 35 centres (a mix of secondary and tertiary referral hospitals) in the UK. We recruited women undergoing primary transvaginal anterior or posterior compartment prolapse surgery by 65 gynaecological surgeons in these centres. We randomly assigned participants by a remote web-based randomisation system to one of the two trials: comparing standard (native tissue) repair alone with standard repair augmented with either synthetic mesh (the mesh trial) or biological graft (the graft trial). We assigned women (1:1:1 or 1:1) within three strata: assigned to one of the three treatment options, comparison of standard repair with mesh, and comparison of standard repair with graft. Participants, ward staff, and outcome assessors were masked to randomisation where possible; masking was obviously not possible for the surgeon. Follow-up was for 2 years after the surgery; the primary outcomes, measured at 1 year and 2 years, were participant-reported prolapse symptoms (i.e. the Pelvic Organ Prolapse Symptom Score [POP-SS]) and condition-specific (ie, prolapse-related) quality-of-life scores, analysed in the modified intention-to-treat population. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN60695184. FINDINGS: Between Jan 8, 2010, and Aug 30, 2013, we randomly allocated 1352 women to treatment, of whom 1348 were included in the analysis. 865 women were included in the mesh trial (430 to standard repair alone, 435 to mesh augmentation) and 735 were included in the graft trial (367 to standard repair alone, 368 to graft augmentation). Because the analyses were carried out separately for each trial (mesh trial and graft trial) some women in the standard repair arm assigned to all treatment options were included in the standard repair group of both trials. 23 of these women did not receive any surgery (15 in the mesh trial, 13 in the graft trial; five were included in both trials) and were included in the baseline analyses only. Mean POP-SS at 1 year did not differ substantially between comparisons (standard 5·4 [SD 5·5] vs mesh 5·5 [5·1], mean difference 0·00, 95% CI -0·70 to 0·71; p=0·99; standard 5·5 [SD 5·6] vs graft 5·6 [5·6]; mean difference -0·15, -0·93 to 0·63; p=0·71). Mean prolapse-related quality-of-life scores also did not differ between groups at 1 year (standard 2·0 [SD 2·7] vs mesh 2·2 [2·7], mean difference 0·13, 95% CI -0·25 to 0·51; p=0·50; standard 2·2 [SD 2·8] vs graft 2·4 [2·9]; mean difference 0·13, -0·30 to 0·56; p=0·54). Mean POP-SS at 2 years were: standard 4·9 (SD 5·1) versus mesh 5·3 (5·1), mean difference 0·32, 95% CI -0·39 to 1·03; p=0·37; standard 4·9 (SD 5·1) versus graft 5·5 (5·7); mean difference 0·32, -0·48 to 1·12; p=0·43. Prolapse-related quality-of-life scores at 2 years were: standard 1·9 (SD 2·5) versus mesh 2·2 (2·6), mean difference 0·15, 95% CI -0·23 to 0·54; p=0·44; standard 2·0 (2·5) versus graft 2·2 (2·8); mean difference 0·10, -0·33 to 0·52; p=0·66. Serious adverse events such as infection, urinary retention, or dyspareunia or other pain, excluding mesh complications, occurred with similar frequency in the groups over 1 year (mesh trial: 31/430 [7%] with standard repair vs 34/435 [8%] with mesh, risk ratio [RR] 1·08, 95% CI 0·68 to 1·72; p=0·73; graft trial: 23/367 [6%] with standard repair vs 36/368 [10%] with graft, RR 1·57, 0·95 to 2·59; p=0·08). The cumulative number of women with a mesh complication over 2 years in women actually exposed to synthetic mesh was 51 (12%) of 434. INTERPRETATION: Augmentation of a vaginal repair with mesh or graft material did not improve women's outcomes in terms of effectiveness, quality of life, adverse effects, or any other outcome in the short term, but more than one in ten women had a mesh complication. Therefore, follow-up is vital to identify any longer-term potential benefits and serious adverse effects of mesh or graft reinforcement in vaginal prolapse surgery.

RESUMO

BACKGROUND: CD39 and CD73 are two novel cell surface markers of CD25high Foxp3+ regulatory T-cells (Tregs). Concordant expression of these two ectoenzymes not only discriminate Tregs from other cell populations, but also generates pericellular adenosine, which has been reported to suppress proliferation of activated T effector (Teff) cells. Because it is currently unclear whether human ectoenzymes (CD39/CD73) are involved in the impaired suppressive activity of Tregs in psoriasis, we examined the frequencies and phenotypes of CD39/CD73-expressing Tregs and related receptor adenosine receptor 2A (A2A R) in peripheral blood of patients with different types of psoriasis. METHODS: Peripheral blood mononuclear cells (PMBC) were prepared from patients with three different types of psoriasis (psoriasis vulgaris, pustular psoriasis and erythrodermic psoriasis). CD4+ cells were separated from PBMC by negative selection on midiMACS columns, and the frequencies and phenotypes of CD39 and CD73 expressing Tregs, and A2A R expressing Teff were all determined by flow cytometry analysis. Blood from healthy volunteers served as controls. RESULTS: The expression of single CD73+ Tregs was markedly reduced (approximately 50%) in psoriasis vulgaris, compared to normal controls. In pustular psoriasis, the mean numbers of CD39+ Tregs and A2A R+ Teff was significantly lower than in normal controls. Among three different types of psoriasis, CD39 expression was strikingly reduced in the blood Treg population of pustular psoriasis patients. Decreased CD73+ Tregs levels were observed in psoriasis vulgaris compared to pustular psoriasis and erythrodermic psoriasis. CONCLUSIONS: The differences in the expression of CD39- and CD73- Tregs may be a factor in the pathogenesis of psoriasis.

RESUMO

Meat has been identified as one of the food categories at most risk of food fraud. Meat species substitution has been in the spotlight with the European horse meat scandal in 2013. Analysis of cases reported on the web shows that incidents of meat substitution are still recurring worldwide. Altogether these cases highlight significant weaknesses in the supply chain transparency and traceability of raw meat materials. This has triggered recent progress from the food industry to apply new software tools enabling the mapping of meat supply chains. Nevertheless, a meat vulnerability assessment showed that meat and derivatives are highly susceptible to many fraudulent malpractices. Therefore, more effective measures are needed to manage the risk and new analytical solutions are required to increase the deterrence of meat adulteration and rapid detection of fraud. DNA-based methods have evolved rapidly as shown with the application of the new LCD array and Next Generation Sequencing (NGS) in order to detect broad meat species adulteration. Moreover, new technologies such as NGS together with the Rapid Evaporative Ionization Mass Spectrometry (REIMS) are emerging as a really promising association of analytical approaches for rapid detection of several malpractices.

RESUMO

According to the 2015 National Survey on Drug Use and Health, cannabis (marijuana) is the most commonly used recreational drug in the US. Among pregnant women aged 14-55 years, 3.4% were cannabis users. Presently, little is known about the neurodevelopmental effect of cannabis use during pregnancy and/or nursing on neonates. Endothelin (ET) is essential for normal development of the central nervous system (CNS). Decreases in ETB receptor expression correlate with a decline in nerve growth factor (NGF) and an increase in vascular endothelial growth factor (VEGF) in postnatal brain. Activation of ETB and cannabinoid 1 (CB1) receptors each promote neurogenesis and enhance angiogenesis, indicating that both ET and CB systems play a critical role during early CNS development. Hence the purpose of this study was to determine whether maternal CB abuse during pregnancy and lactation alters the expression of ETB receptors, CB1 receptors, VEGF, and NGF in the postnatal rat brain. Sixteen pregnant Sprague-Dawley rats were administered either saline or anandamide (AEA) at a dose of 3 mg/kg/day i.p. from gestational day 7 and continued through weaning on postnatal day (PND) 21. Rat pups were subdivided into 4 subgroups and sacrificed on PND 2, 7, 14, and 28. Brain tissue of the pups and dams (sacrificed on PND 21) was analyzed via Western blot for the expression of ETB receptors, CB1 receptors, VEGF, and NGF. AEA-exposed dams had significantly fewer live births (p = 0.027), and their pups presented with significantly lower body weights on PND 7 (p = 0.013) and PND 28 (p = 0.018). There was no significant difference noted in ETB receptor, CB1 receptor, NGF, or VEGF expression in the pup brains. In all pups, brain ETB receptor expression decreased and CB1 receptor expression increased with age. In the AEA-exposed dam brain, however, there was a decrease in ETB receptor (p = 0.043) and an increase in CB1 receptor expression (p = 0.033). AEA exposure during pregnancy appears to affect fetal viability and postnatal weight gain in offspring while not altering the expression patterns of ETB receptors, CB1 receptors, NGF, or VEGF in the pup brain. The observed trend to an increase in CB1 receptor expression concurrent with a decrease in ETB receptor expression in both dams and pups may point to a homeostatic regulation between these 2 systems in CNS development and neuroprotection.

RESUMO

We previously observed that aquaporin-3 and aquaporin-10 are upregulated in the epidermis of hand dermatitis patients (Med. Hypotheses, 84, 2015, 498). To address the functional relevance of this upregulation, we overexpressed AQP3/AQP10 in mice using the human K1 promoter. Combining imiquimod with detergent-containing water challenge, a common trigger in hand and other dermatitis, resulted in an increase in acanthosis in mice overexpressing AQP3 or AQP3 and AQP10. Aquaporin overexpression also drove a trend towards greater weight loss in these animals. These data support a role for cutaneous aquaporins in the pathogenesis of dermatitis and as a potential target in their treatment.

RESUMO

Glioblastoma (GBM) is the most aggressive and lethal type of brain cancer with a median survival of less than two years even following aggressive treatment (Stupp et al., N Engl J Med 352:987-996, 2005). Among the many challenges in treating patients with this devastating disease is the ability to differentiate Magnetic Resonance Imaging (MRI) images that appear following radiation therapy, often termed "radiation necrosis" from true GBM recurrence. Radiation necrosis (RN) and GBM are very difficult to distinguish and currently only a brain biopsy can conclusively differentiate these pathologies. In the present study, we introduce a differential diagnostic approach using a newly identified Myeloid-Derived Suppressor Cell (MDSC) biomarker, vascular non-inflammatory molecule 2 (VNN2+), in combination with expression of traditional HLA-DR on peripheral blood CD14+ monocytes isolated from GBM and/or RN patients. We performed proof-of-principle experiments confirming the sensitivity and specificity of this approach based upon the combined expression levels of HLA-DR and VNN2 among CD14+ Mo-MDSC, which we called the DR-Vanin Index or DVI. The DVI was able to distinguish GBM from RN patients with a high degree of certainty (n = 18 and n = 6 respectively; p = 0.0004). This novel, quick and inexpensive blood-based liquid biopsy could potentially replace invasive brain biopsies in differentiating GBM from RN patients using a minimally-invasive technique.

RESUMO

BACKGROUND: An urgent need exists in the United States to establish treatment goals in psoriasis. OBJECTIVE: We aim to establish defined treatment targets toward which clinicians and patients with psoriasis can strive to inform treatment decisions, reduce disease burden, and improve outcomes in practice. METHODS: The National Psoriasis Foundation conducted a consensus-building study among psoriasis experts using the Delphi method. The process consisted of: (1) literature review, (2) pre-Delphi question selection and input from general dermatologists and patients, and (3) 4 Delphi rounds. RESULTS: A total of 25 psoriasis experts participated in the Delphi process. The most preferred instrument was body surface area (BSA). The most preferred time for evaluating patient response after starting new therapies was at 3 months. The acceptable response at 3 months postinitiation was either BSA 3% or less or BSA improvement 75% or more from baseline. The target response at 3 months postinitiation was BSA 1% or less. During the maintenance period, evaluation every 6 months was most preferred. The target response at every 6 months maintenance evaluation is BSA 1% or less. LIMITATIONS: Although BSA is feasible in practice, it does not encompass health-related quality of life, costs, and risks of side effects. CONCLUSION: With defined treatment targets, clinicians and patients can regularly evaluate treatment responses and perform benefit-risk assessments of therapeutic options individualized to the patient.

RESUMO

Psoriasis patients exhibit an increased risk of death by cardiovascular disease (CVD) and have elevated levels of circulating intermediate (CD14(++)CD16(+)) monocytes. This elevation could represent evidence of monocyte dysfunction in psoriasis patients at risk for CVD, as increases in circulating CD14(++)CD16(+) monocytes are predictive of myocardial infarction and death. An elevation in the CD14(++)CD16(+) cell population has been previously reported in patients with psoriatic disease, which has been confirmed in the cohort of our human psoriasis patients. CD16 expression was induced in CD14(++)CD16(-) classical monocytes following plastic adhesion, which also elicited enhanced ß2 but not ß1 integrin surface expression, suggesting increased adhesive capacity. Indeed, we found that psoriasis patients have increased monocyte aggregation among circulating PBMCs, which is recapitulated in the KC-Tie2 murine model of psoriasis. Visualization of human monocyte aggregates using imaging cytometry revealed that classical (CD14(++)CD16(-)) monocytes are the predominant cell type participating in these aggregate pairs. Many of these pairs also included CD16(+) monocytes, which could account for apparent elevations of intermediate monocytes. Additionally, intermediate monocytes and monocyte aggregates were the predominant cell type to adhere to TNF-α- and IL-17A-stimulated dermal endothelium. Ingenuity Pathway Analysis demonstrated that monocyte aggregates have a distinct transcriptional profile from singlet monocytes and monocytes following plastic adhesion, suggesting that circulating monocyte responses to aggregation are not fully accounted for by homotypic adhesion, and that further factors influence their functionality.

RESUMO

BACKGROUND: Anterior vaginal repair (anterior colporrhaphy) is an operation traditionally used for moderate or severe stress urinary incontinence (SUI) in women. About a third of adult women experience urinary incontinence. SUI imposes significant health and economic burden to the society and the women affected. OBJECTIVES: To determine the effects of anterior vaginal repair (anterior colporrhaphy) on urinary incontinence in comparison with other management options. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Trials Register (searched 1 September 2009) and the reference lists of relevant articles. SELECTION CRITERIA: Randomised or quasi-randomised trials that included anterior vaginal repair for the treatment of urinary incontinence. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed trial quality. Three trial investigators were contacted for additional information. MAIN RESULTS: Ten trials were identified which included 385 women having an anterior vaginal repair and 627 who received comparison interventions.A single small trial provided insufficient evidence to assess anterior vaginal repair in comparison with physical therapy. The performance of anterior repair in comparison with bladder neck needle suspension appeared similar (risk ratio (RR) for failure after one year 1.16, 95% confidence interval (CI) 0.86 to 1.56), but clinically important differences could not be confidently ruled out. No trials compared anterior repair with suburethral sling operations or laparoscopic colposuspensions, or compared alternative vaginal operations.Anterior vaginal repair was less effective than open abdominal retropubic suspension based on patient-reported cure rates in eight trials both in the medium term (failure rate within one to five years after anterior repair 97/259 (38%) versus 57/327 (17%); RR 2.29, 95% confidence Interval (CI) 1.70 to 3.08) and in the long term (after five years, (49/128 (38%) versus 31/145 (21%); RR 2.02, 95% CI 1.36 to 3.01). There was evidence from three of these trials that this was reflected in a need for more repeat operations for incontinence (25/107 (23%) versus 4/164 (2%); RR 8.87, 95% CI 3.28 to 23.94). These findings held, irrespective of the co-existence of prolapse (pelvic relaxation). Although fewer women had a prolapse after anterior repair (RR 0.24, 95% CI 0.12 to 0.47), later prolapse operation appeared to be equally common after vaginal (3%) or abdominal (4%) operation.In respect of the type of open abdominal retropubic suspension, most data related to comparisons of anterior vaginal repair with Burch colposuspension. The few data describing comparison of anterior repair with the Marshall-Marchetti-Krantz procedure were consistent with those for Burch colposuspension. AUTHORS' CONCLUSIONS: There were not enough data to allow comparison of anterior vaginal repair with physical therapy or needle suspension for primary urinary stress incontinence in women. Open abdominal retropubic suspension appeared to be better than anterior vaginal repair judged on subjective cure rates in eight trials, even in women who had prolapse in addition to stress incontinence (six trials). The need for repeat incontinence surgery was also less after the abdominal operation. However, there was not enough information about postoperative complications and morbidity.A Brief Economic Commentary (BEC) identified one study suggesting that vaginoplasty may be more cost-effective compared with tension-free vaginal tape (TVT-O).

RESUMO

BACKGROUND: Bladder neck needle suspension is an operation traditionally used for moderate or severe stress urinary incontinence in women. About a third of adult women experience some urinary incontinence, and about a third of these have moderate or severe symptoms. Stress urinary incontinence (SUI) imposes significant health and economic burdens on society and the women affected. OBJECTIVES: To determine the effects of needle suspension on stress or mixed urinary incontinence in comparison with other management options. SEARCH METHODS: We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 12 November 2014), and the reference lists of relevant articles. SELECTION CRITERIA: Randomised or quasi-randomised trials that included needle suspension for the treatment of urinary incontinence. DATA COLLECTION AND ANALYSIS: At least two authors assessed trials and extracted data independently. Two trial investigators provided additional information. MAIN RESULTS: We identified 10 trials, which included 375 women having six different types of needle suspension procedures and 489 who received comparison interventions. Needle suspensions were more likely to fail than open abdominal retropubic suspension. There was a higher subjective failure rate after the first year (91/313 (29%) failed versus 47/297 (16%) failed after open abdominal retropubic suspension). The risk ratio (RR) was 2.00 (95% confidence interval (CI) 1.47 to 2.72), although the difference in peri-operative complications was not significant (17/75 (23%) versus 12/77 (16%); RR 1.44, 95% CI 0.73 to 2.83). There were no significant differences for the other outcome measures. This effect was seen in both women with primary incontinence and women with recurrent incontinence after failed primary operations. Needle suspensions may be as effective as anterior vaginal repair (50/156 (32%) failed after needle suspension versus 64/181 (35%) after anterior repair; RR 0.86, 95% CI 0.64 to 1.16), but there was little information about morbidity. Data for comparison with suburethral slings were inconclusive because they came from a small and atypical population.No trials compared needle suspensions with conservative management, peri-urethral injections, or sham or laparoscopic surgery. AUTHORS' CONCLUSIONS: Bladder neck needle suspension surgery is probably not as good as open abdominal retropubic suspension for the treatment of primary and secondary urodynamic stress incontinence because the cure rates were lower in the trials reviewed. However, the reliability of the evidence was limited by poor quality and small trials. There was not enough information to comment on comparisons with suburethral sling operations. Although cure rates were similar after needle suspension compared with after anterior vaginal repair, the data were insufficient to be reliable and inadequate to compare morbidity. A Brief Economic Commentary (BEC) identified no cost-effectiveness studies comparing bladder neck needle suspension with other surgeries.

RESUMO

BACKGROUND/PURPOSE: Psoriasis continues to be a debilitating skin disease affecting 1-3% of the United States population. Although the effectiveness of several current biologic therapies have described this pathology as a IL-23, TNF-a and Th17-mediated disease, less invasive approaches are still in use and in need of refinement. One of these is the usage of narrow band-UVB (NB-UVB) therapy to deplete specifically intra-epidermal CD3+, CD4+ and CD8+ cells to clear psoriatic plaques. AIMS/OBJECTIVES: In order to improve NB-UVB therapy, we sought to determine whether skin pre-treatment with the TLR7 agonist imiquimod (IMQ) would help increase the efficiency of the former at resolving psoriatic plaques. MATERIALS AND METHODS: Eucerin® Original Moisturizing Lotion (topical vehicle) or Aldara® (imiquimod 5% topical cream) were applied for 5 days once daily to a maximum contiguous area of 25 cm2 (5 cm × 5 cm area). Patients were provided with sachets containing 12.5 mg of imiquimod each and were instructed to apply imiquimod (I) to two psoriasis plaques (5 sachets of imiquimod allotted to each plaque). A PHAROS excimer Laser EX-308 (Ra Medical Systems, Inc. Carlsbad, CA, USA) with an output of monochromatic 308-nm light and pulse width of 20-50 ns was used for all patients. Punch biopsies of psoriatic lesions (6 mm) were taken at 4 and 48 h after final application of topical treatment with or without excimer laser treatment. Real-time quantitative RT-PCR was performed according to manufacturer's instructions and Inmunohistochemistry was used as described before. RESULTS: Our results suggests that although IMQ seemed to activate the type I interferon pathway as previously described, its concomitant usage with NB-UVB for clearing psoriatic skin was ineffective. Although upregulation of genes MxA, GRAMD1A and DMXL2 suggested that IMQ treatment did induce skin changes in psoriasis patients, more optimal dosing of IMQ and NB-UVB might be necessary to achieve desired treatment responses. CONCLUSION: The observation that psoriasis involvement was not aggravated by usage of topical IMQ was encouraging. Additional observational studies might be necessary to further tailor the combination of IMQ with NB-UVB therapy to reliably improve the psoriatic pathology.

RESUMO

Photodynamic therapy (PDT) is an emerging treatment for malignant and inflammatory dermal disorders. Photoirradiation of the silicon phthalocyanine (Pc) 4 photosensitizer with red light generates singlet oxygen and other reactive oxygen species to induce cell death. We previously reported that Pc 4-PDT elicited cell death in lymphoid-derived (Jurkat) and epithelial-derived (A431) cell lines in vitro, and furthermore that Jurkat cells were more sensitive than A431 cells to treatment. In this study, we examined the effectiveness of Pc 4-PDT on primary human CD3(+) T cells in vitro. Fluorometric analyses of lysed T cells confirmed the dose-dependent uptake of Pc 4 in non-stimulated and stimulated T cells. Flow cytometric analyses measuring annexin V and propidium iodide (PI) demonstrated a dose-dependent increase of T cell apoptosis (6.6-59.9%) at Pc 4 doses ranging from 0-300 nM. Following T cell stimulation through the T cell receptor using a combination of anti-CD3 and anti-CD28 antibodies, activated T cells exhibited increased susceptibility to Pc 4-PDT-induced apoptosis (10.6-81.2%) as determined by Pc 4 fluorescence in each cell, in both non-stimulated and stimulated T cells, Pc 4 uptake increased with Pc 4 dose up to 300 nM as assessed by flow cytometry. The mean fluorescence intensity (MFI) of Pc 4 uptake measured in stimulated T cells was significantly increased over the uptake of resting T cells at each dose of Pc 4 tested (50, 100, 150 and 300 nM, p < 0.001 between 50 and 150 nM, n = 8). Treg uptake was diminished relative to other T cells. Cutaneous T cell lymphoma (CTCL) T cells appeared to take up somewhat more Pc 4 than normal resting T cells at 100 and 150 nm Pc 4. Confocal imaging revealed that Pc 4 localized in cytoplasmic organelles, with approximately half of the Pc 4 co-localized with mitochondria in T cells. Thus, Pc 4-PDT exerts an enhanced apoptotic effect on activated CD3(+) T cells that may be exploited in targeting T cell-mediated skin diseases, such as cutaneous T cell lymphoma (CTCL) or psoriasis.
