Sacrospinous colpopexy versus McCall’s culdoplasty during vaginal hysterectomy in stage 3 and 4 prolapse for prevention of vault prolapse

Background: Pelvic organ prolapse is a common condition seen in women due to weakening of support of pelvic organs. Different surgical procedures have been adopted for suspension of vaginal vault during vaginal hysterectomy to restore vault to near normal anatomic position as preventive measures for vault prolapse. The aim of study was to compare the efficacy of the McCall’s culdoplasty and sacrospinous ligament colpopexy in stage 3 and 4 prolapse (POP-Q).Methods: This prospective study comprised 100 women presenting with stage 3 and 4 prolapse (POP-Q). They were divided into two equal groups of 50 each. The patients were randomized to undergo McCall’s culdoplasty (Group A) or sacrospinous ligament fixation (Group B) with vaginal hysterectomy based on note contained in an envelope comparative analysis was done, and patients were evaluated for intra-operative difficulties and immediate (48 hours) post-operative complications using SPSS-version 23 for statistical analysis. The patients were followed up at one month and one year to evaluate symptomatically and objectively.Results: In group A, patients with 3-degree prolapse 1 woman had hemorrhage and 1 woman had bladder injury intraoperatively. Whereas in group B, 5 women had hemorrhage and 1 woman had rectal injury intraoperatively. All complications were dealt successfully. No other major intra- and post-operative complications occurred.Conclusions: Vaginal hysterectomy with sacrospinous colpopexy resulted in better outcomes after surgery. Hence, it was concluded that unilateral or bilateral SSLF may be added to vaginal hysterectomy in patients of stage 3 or 4 prolapse

Candida albicans biofilms: development, regulation, and molecular mechanisms

A major virulence attribute of Candida albicans is its ability to form biofilms, densely packed communities of cells adhered to a surface. These biofilms are intrinsically resistant to conventional antifungal therapeutics, the host immune system, and other environmental factors, making biofilm-associated infections a significant clinical challenge. Here, we review current knowledge on the development, regulation, and molecular mechanisms of C. albicans biofilms

Visualization of Biofilm Formation in Candida albicans Using an Automated Microfluidic Device.

Candida albicans is the most common fungal pathogen of humans, causing about 15% of hospital-acquired sepsis cases. A major virulence attribute of C. albicans is its ability to form biofilms, structured communities of cells attached to biotic and abiotic surfaces. C. albicans biofilms can form on host tissues, such as mucosal layers, and on medical devices, such as catheters, pacemakers, dentures, and joint prostheses. Biofilms pose significant clinical challenges because they are highly resistant to physical and chemical perturbations, and can act as reservoirs to seed disseminated infections. Various in vitro assays have been utilized to study C. albicans biofilm formation, such as microtiter plate assays, dry weight measurements, cell viability assays, and confocal scanning laser microscopy. All of these assays are single end-point assays, where biofilm formation is assessed at a specific time point. Here, we describe a protocol to study biofilm formation in real-time using an automated microfluidic device under laminar flow conditions. This method allows for the observation of biofilm formation as the biofilm develops over time, using customizable conditions that mimic those of the host, such as those encountered in vascular catheters. This protocol can be used to assess the biofilm defects of genetic mutants as well as the inhibitory effects of antimicrobial agents on biofilm development in real-time

S‐nitrosomycothiol reductase and mycothiol are required for survival under aldehyde stress and biofilm formation in Mycobacterium smegmatis

We show that Mycobacterium smegmatis mutants disrupted in mscR, coding for a dual function S-nitrosomycothiol reductase and formaldehyde dehydrogenase, and mshC, coding for a mycothiol ligase and lacking mycothiol (MSH), are more susceptible to S-nitrosoglutathione (GSNO) and aldehydes than wild type. MSH is a cofactor for MscR, and both mshC and mscR are induced by GSNO and aldehydes. We also show that a mutant disrupted in egtA, coding for a γ-glutamyl cysteine synthetase and lacking in ergothioneine, is sensitive to nitrosative stress but not to aldehydes. In addition, we find that MSH and S-nitrosomycothiol reductase are required for normal biofilm formation in M. smegmatis, suggesting potential new therapeutic pathways to target to inhibit or disrupt biofilm formation. © 2016 IUBMB Life, 68(8):621-628, 2016

Development and regulation of single- and multi-species Candida albicans biofilms

Candida albicans is among the most prevalent fungal species of the human microbiota and asymptomatically colonizes healthy individuals. However, it is also an opportunistic pathogen that can cause severe, and often fatal, bloodstream infections. The medical impact of C. albicans typically depends on its ability to form biofilms, which are closely packed communities of cells that attach to surfaces, such as tissues and implanted medical devices. In this Review, we provide an overview of the processes involved in the formation of C. albicans biofilms and discuss the core transcriptional network that regulates biofilm development. We also consider some of the advantages that biofilms provide to C. albicans in comparison with planktonic growth and explore polymicrobial biofilms that are formed by C. albicans and certain bacterial species

Prospective Clinical Study to Find out Epidemiology of Xerophthalmia in Children in a Tertiary Care Centre in India

Objective: To study the epidemiology of xerophthalmia in children 2-6 years of age in North India. Methods: A prospective clinical study was done at two tertiary care centers of North India between 2010 to 2016, Cases were selected from routine OPD and children less than 6 years of age were examined by an ophthalmologist. Diagnosis and classification of Xerophthalmia was done according to WHO classification. All the data recording demographic profile, socioeconomic status, other health problems etc were recorded in a fixed proforma. Data was analyzed by SPSS version 16. Findings: Two thousand nine hundred forty six cases were included in the study after satisfying inclusion and exclusion criteria. The prevalence of night blindness was estimated to be 2.93% (95% Confidence Interval [CI]: 2.53-3.33) among children between 2 and 6 years of age. Xerophthalmia prevalence was 4.43% (95% CI: 4.19-4.67). Prevalence was more in girls than boys and higher in low socioeconomic status. Conclusion: Vitamin A deficiency is recognized to be a severe public health problem leading to corneal opacity and childhood blindness in most of the areas of North Indi
