    Bacterial vaginosis (BV) is a common vaginal syndrome associated with altered microflora that increases the risk of preterm delivery and acquisition of sexually transmitted diseases. The cause of BV is unknown although toll-like receptors (TLRs), that are central to innate immune responses, may be important. We evaluated associations between TLR SNPs and BV among HIV-1 infected and uninfected African women. Logistic regression was used to assess associations between SNPs (N=99) in TLRs 2-4, 7-9 and BV (as classified by Nugent's criteria). Among HIV-1 uninfected women, TLR7 rs5743737 and TLR7 rs1634323 were associated with a decreased risk of BV, whereas TLR7 rs179012 was associated with an increased risk. TLR2 SNP rs3804099 was associated with a decreased risk of BV among HIV-1 infected women. Our findings indicate that there may be differences in TLR association with BV among HIV-1 infected and HIV-1 uninfected women

    Background: Vertebral tuberculosis is the most common form of skeletal tuberculosis and it contributes about 50 percent of all cases of skeletal tuberculosis. The purpose of this study is to delineate the importance of middle path regime and short course chemotheraphy in the management of spine tuberculosis.Methods: A prospective study was conducted which included 44 patients diagnosed as tuberculous spondylitis. Management was started as per middle path regime and drugs were given as per the revised national tuberculosis control program (RNTCP) regime category I under directly observed treatment, short-course (DOTS) therapy. Specimen was collected and studied for smear, culture, antibiotic sensitivity and histopathology. ATT was stopped at the end of 6 months as per DOTS schedule and MRI was done at the end of therapy.Results: Dorsal spine lesions were found in 33 patients. 8 patients were smear positive and 38 patients were culture positive of whom 26 patients were sensitive to first line ATT drugs. 12 patients had MDR tuberculosis and were sensitive to 2nd line ATT drugs. 6 patients having negative culture were diagnosed from histopathology. All patients on 1st line ATT had satisfactory result. Only 8 patients with MDR tuberculosis recovered neurologically. Conclusions: It is mandatory to do obtain tissue biopsy and examine culture, sensitivity and histopathology. Recently there is an increasing tendency in multidrug resistance cases and total drug resistant cases. By doing culture and sensitivity of the specimen we can find out the number of MDR cases and initiate proper drug regimen to avoid further complication and mortality

    The mechanism(s) by which bacterial communities impact susceptibility to infectious diseases, such as HIV, and maintain female genital tract (FGT) health are poorly understood. Evaluation of FGT bacteria has predominantly been limited to studies of species abundance, but not bacterial function. We therefore sought to examine the relationship of bacterial community composition and function with mucosal epithelial barrier health in the context of bacterial vaginosis (BV) using metaproteomic, metagenomic, and in vitro approaches. We found highly diverse bacterial communities dominated by Gardnerella vaginalis associated with host epithelial barrier disruption and enhanced immune activation, and low diversity communities dominated by Lactobacillus species that associated with lower Nugent scores, reduced pH, and expression of host mucosal proteins important for maintaining epithelial integrity. Importantly, proteomic signatures of disrupted epithelial integrity associated with G. vaginalis-dominated communities in the absence of clinical BV diagnosis. Because traditional clinical assessments did not capture this, it likely represents a larger underrepresented phenomenon in populations with high prevalence of G. vaginalis. We finally demonstrated that soluble products derived from G. vaginalis inhibited wound healing, while those derived from L. iners did not, providing insight into functional mechanisms by which FGT bacterial communities affect epithelial barrier integrity

    Background: Ankle fractures represent approximately 9% of all fractures and are a common occurrence with an incidence of 138-169 per 100,000 per year. The mechanism of injury differs in terms of mode of injury in various age groups. The Lague-Hansen classification is a pathologic-anatomic classification and emphasizes different stages of ligamentous injury, in addition to the fracture pattern, and provides options for fracture treatment.Methods: A retrospective observational study, where the prevalence of various types of ankle fractures were classified according to the Lauge-Hansen Classification, in the period of 2018 onwards till date. The mode of injury and age group of the patient was also noted.Results: A total of 84 patients were analyzed, supination-external rotation (48.7%) were the most frequently observed fractures in our study population, with no significant correlation between mode of injury and fracture pattern noted. There was a statistically significant association (p<0.05) between the velocity of injury and the age groups suffering ankle trauma.Conclusion: The Lauge-Hansen Classification continues to be an important tool in assessing the biomechanics of ankle fractures and the management options available, especially in a country like India where more expensive imaging modalities may not be available or affordable at times. Our study also highlights that high velocity fractures continue to be a major cause of morbidity in the younger age group, especially in developing countries such as India. Stringent traffic rules and public awareness need to be put into practice to reduce the toll of this problem

    Background: Outpatient orthopaedics department of a tertiary care hospital sees large number of patients. However, the funds and resources are limited and have to be judiciously distributed. This study aims to study the etiological pattern of different patients that present to the outpatient department (OPD).Methods: Nine consecutive OPD’s data was studied for the etiology of the different diagnosis of new patients presenting to the OPD. Etiology of various diagnoses was studied as a percentage of the total patients.Results: Trauma of upper limb and lower limb formed a higher percentage of the total patients. Degenerative spine was more common than traumatic spine.Conclusions: Traumatic conditions of the lower and upper limb make up majority of the cases. Degenerative spine is more common than the traumatic etiology

    Background: Proximal humeral fractures were treated conservatively in the past and often had compromised functional results. With the advancement of surgical techniques, these fractures, especially displaced, are now more often managed operatively; to meet the needs of the patient, provide early rehabilitation and better functional outcome. The aim of this study was to assess the functional outcome of operative management of proximal humeral fractures with Philos plate fixation.Methods: In this prospective study, 30 patients aged 19-75 years (mean age 47.1 years) with fractures of the proximal humerus, including two-, three-, and four-part fractures, were treated by open reduction internal fixation with Philos plating. Patients’ functional outcomes were evaluated based on subjective (35 points) and objective (65 points) parameters, as per the constant scoring system.Results: Functional outcome based on the constant scoring system of the patient at 6 month follow-up were compared. Excellent results were seen in 12 patients (40%), 2 had very good results (6.66%), 9 patients were having good (30%) and 6 had fair (20%) functional outcome. One patient had poor functional results (3.33%). Avascular necrosis (AVN) of the humeral head was observed in one patients.Conclusions: Philos plate fixation for proximal humeral fractures provides good stable fixation with good functional outcome and is a feasible option.

    Purpose. To quantify the quality of life (QoL) distress experienced by immediate family members of patients with urethral stricture via a questionnaire given prior to definitive urethroplasty. The emotional, social, and physical effects of urethral stricture disease on the QoL of family members have not been previously described. Materials and Methods. A questionnaire was administered prospectively to an immediate family member of 51 patients undergoing anterior urethroplasty by a single surgeon (SBB). The survey was comprised of twelve questions that addressed the emotional, social, and physical consequences experienced as a result of their loved one. Results. Of the 51 surveyed family members, most were female (92.2%), lived in the same household (86.3%), and slept in the same room as the patient (70.6%). Respondents experienced sleep disturbances (56.9%) and diminished social lives (43.1%). 82.4% felt stressed by the patient's surgical treatment, and 83.9% (26/31) felt that their intimacy was negatively impacted. Conclusions. Urethral stricture disease has a significant impact on the family members of those affected. These effects may last decades and include sleep disturbance, decreased social interactions, emotional stress, and impaired sexual intimacy. Treatment of urethral stricture disease should attempt to mitigate the impact of the disease on family members as well as the patient

    Background Accurate methods of HIV incidence determination are critically needed to monitor the epidemic and determine the population level impact of prevention trials. One such trial, Project Accept, a Phase III, community-randomized trial, evaluated the impact of enhanced, community-based voluntary counseling and testing on population-level HIV incidence. The primary endpoint of the trial was based on a single, cross-sectional, post-intervention HIV incidence assessment. Methods and Findings Test performance of HIV incidence determination was evaluated for 403 multi-assay algorithms [MAAs] that included the BED capture immunoassay [BED-CEIA] alone, an avidity assay alone, and combinations of these assays at different cutoff values with and without CD4 and viral load testing on samples from seven African cohorts (5,325 samples from 3,436 individuals with known duration of HIV infection [1 month to >10 years]). The mean window period (average time individuals appear positive for a given algorithm) and performance in estimating an incidence estimate (in terms of bias and variance) of these MAAs were evaluated in three simulated epidemic scenarios (stable, emerging and waning). The power of different test methods to detect a 35% reduction in incidence in the matched communities of Project Accept was also assessed. A MAA was identified that included BED-CEIA, the avidity assay, CD4 cell count, and viral load that had a window period of 259 days, accurately estimated HIV incidence in all three epidemic settings and provided sufficient power to detect an intervention effect in Project Accept. Conclusions In a Southern African setting, HIV incidence estimates and intervention effects can be accurately estimated from cross-sectional surveys using a MAA. The improved accuracy in cross-sectional incidence testing that a MAA provides is a powerful tool for HIV surveillance and program evaluation

    Stable heterosexual HIV-1 serodiscordant couples in Africa have high HIV-1 transmission rates and are a critical population for evaluation of new HIV-1 prevention strategies. The Partners PrEP Study is a randomized, double-blind, placebo-controlled trial of tenofovir and emtricitabine-tenofovir pre-exposure prophylaxis to decrease HIV-1 acquisition within heterosexual HIV-1 serodiscordant couples. We describe the trial design and characteristics of the study cohort.HIV-1 serodiscordant couples, in which the HIV-1 infected partner did not meet national guidelines for initiation of antiretroviral therapy, were enrolled at 9 research sites in Kenya and Uganda. The HIV-1 susceptible partner was randomized to daily oral tenofovir, emtricitabine-tenofovir, or matching placebo with monthly follow-up for 24-36 months.From July 2008 to November 2010, 7920 HIV-1 serodiscordant couples were screened and 4758 enrolled. For 62% (2966/4758) of enrolled couples, the HIV-1 susceptible partner was male. Median age was 33 years for HIV-1 susceptible and HIV-1 infected partners [IQR (28-40) and (26-39) respectively]. Most couples (98%) were married, with a median duration of partnership of 7.0 years (IQR 3.0-14.0) and recent knowledge of their serodiscordant status [median 0.4 years (IQR 0.1-2.0)]. During the month prior to enrollment, couples reported a median of 4 sex acts (IQR 2-8); 27% reported unprotected sex and 14% of male and 1% of female HIV-1 susceptible partners reported sex with outside partners. Among HIV-1 infected partners, the median plasma HIV-1 level was 3.94 log(10) copies/mL (IQR 3.31-4.53) and median CD4 count was 496 cells/µL (IQR 375-662); the majority (64%) had WHO stage 1 HIV-1 disease.Couples at high risk of HIV-1 transmission were rapidly recruited into the Partners PrEP Study, the largest efficacy trial of oral PrEP.
