A comparative study of frequency of postnatal depression among subjects with normal and caesarean deliveries

Background: Prevalence of postnatal depression (PND) is 12-15%. Recent studies are equivocal about the earlier inference that PND is higher among caesarian than normal delivery. Objective: The aim of this study is to investigate the frequency of PND among the Indian women and the association between the mode of delivery and PND. Material and method: Fifty subjects each; having delivered normally and by caesarian section was chosen. All the women were within 3 months post delivery and could understand Kannada language. Those who consented were asked to complete the Edinburgh Postnatal Depression Scale (EPDS). Those found to have scores suggestive of depression on EPDS were assessed for depression according to ICD-10. The data was analyzed using paired t test and chi square test. Result and conclusion: Among Post caesarean subjects, depression was diagnosed in 20% (n=10) as compared to 16% (n=8) in subjects that delivered normally. However there was no significant difference in the frequency of depression among the two groups. Due to the small sample size the results cannot be generalized

Dysplasia epiphysealis hemimelica (Trevor’s disease): a rare case report with oral manifestations

Dysplasia epiphysealis hemimelica, also known as Trevor’s disease, is an extremely rare skeletal developmental disorder of unknown etiology, characterized by an osteocartilaginous outgrowth of one or more epiphyses or of a tarsal bone during childhood. It is a rare skeletal hemimelica disorder characterized by asymmetric growth of cartilage in one or more epiphyses. Due to the unusual presentation and variability of the picture, there is no standardized treatment and outcome is very different. Also such an unusual, unique case with craniofacial manifestations has not been reported in the literature. We report a case of a 14-year-old male, who complained of irregularly placed teeth in upper and lower front teeth region. On general physical examination we noticed some skeletal abnormalities with the patient and hence we subjected him to radiographic investigations. The images were consistent with epiphyseal dysplasia hemimelica. The prognosis of DEH is variable and depends basically on its location and size. Carriers of this unusual dysplasia should be periodically monitored for the risk of recurrence

The long-term hospitalization experience following military service in the 1991 Gulf War among veterans remaining on active duty, 1994–2004

<p>Abstract</p> <p>Background</p> <p>Despite more than a decade of extensive, international efforts to characterize and understand the increased symptom and illness-reporting among veterans of the 1991 Gulf War, concern over possible long-term health effects related to this deployment continue. The purpose of this study was to describe the long-term hospitalization experience of the subset of U.S. Gulf War veterans still on active duty between 1994 and 2004.</p> <p>Methods</p> <p>Gulf War veterans on active duty rosters as of October 1, 1994, were identified (n = 211 642) and compared with veterans who had separated from military service and then assessed for attrition at three-year intervals during a 10-year follow-up period, examining demographic and military service characteristics, Gulf War exposure variables, and hospitalization data. Cox proportional hazard modeling was used to evaluate independent predictors of all-cause hospitalization among those still on active duty and to estimate cumulative probability of hospitalization, 1994–2004, by service branch.</p> <p>Results</p> <p>Members of our 1994 active duty cohort were more likely to be officers, somewhat older, and married compared with those who had separated from the military after serving in the 1991 Gulf War. Selected war-related exposures or experiences did not appear to influence separation with the exception of in-theater presence during the brief ground combat phase. Overall the top three diagnostic categories for hospitalizations were musculo-skeletal, injury and poisoning, and digestive disorders. Diseases of the circulatory system and symptoms, signs, and ill-defined conditions increased proportionately over time. In-theater hospitalization was the only significant independent predictor of long-term hospitalization risk among selected war-related exposures or experiences examined. The cumulative probability of hospitalization was highest for Army and lowest for Marines.</p> <p>Conclusion</p> <p>Our results were generally consistent with a previous hospitalization study of US Gulf War veterans for the period August 1991 to July 1999. Although lack of a comparison group for our study limits interpretation of overall findings, intra-cohort analyses showed no significant associations between long-term hospitalization and war-related exposures or experiences, with the exception of in-theater hospitalization, within our active duty subset of 1991 Gulf War veterans.</p

HIV Status Communication with Sex Partners and Associated Factors Among High-Risk MSM and Transgender Women in Lima, Peru

Men who have sex with men (MSM) and transgender women (TW) are key populations in the HIV epidemic. HIV status communication between sex partners can inform decisions regarding sexual behavior. MSM and TW were asked about HIV status communication with sex partners at baseline, 9- and 18-months. GEE models assessed associations with HIV status communication at baseline using prevalence ratios (PRs) and longitudinally using odds ratios (ORs). At baseline, those who had previously had an HIV test, disclosed their HIV status to 42&nbsp;% of their sex partners. HIV status communication was associated with knowing their sex partner's HIV status at baseline (aPR 5.20) and longitudinally (aOR 1.86). HIV positivity at baseline was negatively associated with HIV status communication during follow-up (aOR 0.55). All reported aPRs and aORs have p&nbsp;&lt;&nbsp;0.05. Interventions promoting HIV status communication and more frequent HIV testing should be explored as current efforts are insufficient

Label-free measuring and mapping of binding kinetics of membrane proteins in single living cells

Membrane proteins (MPs) mediate a variety of cellular responses to extracellular signals. While MPs are intensely studied for their values as disease biomarkers and therapeutic targets, in situ investigation of binding kinetics of MPs with their ligands has been a challenge. Traditional approaches isolate MPs and then study them ex situ, which does not accurately reflect their native structures and functions. We present here a label-free plasmonic microscopy method to map the local binding kinetics of MPs in their native environment. This new analytical method can perform simultaneous plasmonic and fluorescence imaging, thus making it possible to combine the strengths of both label-based and label-free techniques in one system. Using this method, we have determined the distribution of MPs on the surface of single cells, and the local binding kinetic constants of different MPs. Furthermore, we have studied the polarization of the MPs on the cell surface during chemotaxis
