Introduction:Rhabdomyolysis (RM) is a condition where there is injury to striated muscle fibers causing release of myoglobin, creatine phosphokinase (CPK), and other intracellular contents into the circulation. High myoglobin levels cause acute kidney injury (AKI). Trauma is the most common cause of RM and development of complications related to the degree of myoglobin released. Currently, the degree of RM is assessed and treatment is instituted based on serum CPK. As myoglobin is the direct cause of AKI, we set out to determine if serum myoglobin is a more reliable predictor than CPK for the development of AKI in traumatic RM.Methodology:A prospective observational study of 90 patients was admitted to the surgical Intensive Care Unit/high dependency unit of a tertiary hospital with traumatic RM whose serum CPK >5000 U/L. Along with standard treatment including intravascular volume optimization and hemodynamic stabilization, they were treated with “crush protocol.” Daily/twice a day, serum CPK and myoglobin were estimated. Categorical data are expressed as frequency and percentage, and the continuous variables are presented as mean (standard deviation) or median (interquartile range) based on normality. Other statistical analyses were done using the Chi-square test, independent t-test, and rank sum test based on normality.Results:Fourteen out of 90 patients developed AKI and one patient required renal replacement therapy. CPK value of >12,000 U/l was identified to have 64% sensitivity and 56% specificity for developing AKI whereas serum myoglobin value of >5000 ng/ml was identified to have 78% sensitivity and 77% specificity for developing AKI.Conclusion:Following traumatic RM, in patients on “crush protocol,” serum myoglobin is a more sensitive and specific test than serum CPK, for predicting AKI.
IntroductionSocioeconomic status (SES) scales measure poverty, wealth and economic inequality in a population to guide appropriate economic and public health policies. Measurement of poverty and comparison of material deprivation across nations is a challenge. This study compared four SES scales which have been used locally and internationally and evaluated them against childhood stunting, used as an indicator of chronic deprivation, in urban southern India.MethodsA door-to-door survey collected information on socio-demographic indicators such as education, occupation, assets, income and living conditions in a semi-urban slum area in Vellore, Tamil Nadu in southern India. A total of 7925 households were categorized by four SES scales—Kuppuswamy scale, Below Poverty Line scale (BPL), the modified Kuppuswamy scale, and the multidimensional poverty index (MDPI) and the level of agreement compared between scales. Logistic regression was used to test the association of SES scales with stunting.FindingsThe Kuppuswamy, BPL, MDPI and modified Kuppuswamy scales classified 7.1%, 1%, 5.5%, and 55.3% of families as low SES respectively, indicating conservative estimation of low SES by the BPL and MDPI scales in comparison with the modified Kuppuswamy scale, which had the highest sensitivity (89%). Children from low SES classified by all scales had higher odds of stunting, but the level of agreement between scales was very poor ranging from 1%-15%.ConclusionThere is great non-uniformity between existing SES scales and cautious interpretation of SES scales is needed in the context of social, cultural, and economic realities.
Birth weight is used as a proxy for the general health condition of newborns. Low birth weight leads to adverse events and its effects on child growth are both short- and long-term. Low birth weight babies are more common in twin gestations. The aim of this study was to assess the effects of maternal and socio-demographic risk factors at various quantiles of the birth weight distribution for twin gestations using quantile regression, a robust semi-parametric technique. Birth records of multiple pregnancies from between 1991 and 2005 were identified retrospectively from the birth registry of the Christian Medical College and hospitals in Vellore, India. A total of 1304 twin pregnancies were included in the analysis. Demographic and clinical characteristics of the mothers were analysed. The mean gestational age of the twins was 36 weeks with 51% having preterm labour. As expected, the examined risk factors showed different effects at different parts of the birth weight distribution. Gestational age, chroniocity, gravida and child's sex had significant effects in all quantiles. Interestingly, mother's age had no significant effect at any part of the birth weight distribution, but both maternal and paternal education had huge impacts in the lower quantiles (10th and 25th), which were underestimated by the ordinary least squares (OLS) estimates. The study shows that quantile regression is a useful method for risk factor analysis and the exploration of the differential effects of covariates on an outcome, and exposes how OLS estimates underestimate and overestimate the effects of risk factors at different parts of the birth weight distribution.
Background: The objective of the present study was to observe the post void residual volume (PVRV) in women with pelvic organ prolapse (POP) pre and postoperatively and to correlate stage of prolapse with lower urinary tract symptoms and quality of life in women with pelvic organ prolapse.Methods: This is a prospective observational cohort study of 100 women with symptomatic pelvic organ prolapse of stage II or greater. Patients were admitted for Vaginal hysterectomy with pelvic floor repair for pelvic organ prolapse in Gynaecology Department at Christian Medical College Hospital, Vellore, India over one year were recruited. This study was approved by the institutional review board and ethical committee of the hospital. Pre- and post-operative PVR were measured. The statistical analysis was done by using SPSS version 21 and P value < 0.05 was considered as statistically significant.Results: In this study 100 patients were recruited and 11% of women had pre-operative high post void residual volume of more than 100 ml. Stages of POP did not correlate with severity of LUTS and QOL. Pre-operative elevated PVR resolved post operatively in 91%, the P value <0.000 which was highly significant.Conclusions: 11% of women had preoperative high PVR. Stages of POP did not correlate with severity of lower urinary tract symptoms (LUTS) and quality of life(QOL). Pre-operative elevated PVR resolved post operatively in 91%, the P value < 0.000 which was highly significant. Majority of the patient with severe pelvic organ prolapse had elevated pre-op PVR which resolved post- operatively after surgical correction.
Objectives: 1. To formulate a normative data/Research data of maxillary arch dimension and cleft width in UCLP patients. 2. To formulate a Posterior cleft width prediction equation using anterior cleft width, which will help in organising the future treatment plan in the required sequence. Materials and Methods: A Sample of 20 unilateral CLP patients were selected from a patient pool who had reported to CMCH, for treatment. This study was approved by ethical committee at CMCH, Vellore. Inclusion criteria: 1. Models of patients with unilateral CLP were selected. 2. Models were taken before any Presurgical manipulation of hard or soft tissues was done. 3. Age of the patient was 3 to 4 months without any treatment began. Methods: The landmarks anterior, mid, posterior arch width was marked on the Study Model measurements were made using the digital Vernier caliper Figure and documented on excel worksheets. Data were summarized using mean and standard deviation. We used a linear regression model to identify the prediction equation of posterior having posterior as an outcome and anterior as predictor. The scatterplot with the linear fit was used to visualize the prediction. All the data were analyzed using STATA IC/16.0. Results: 1. Normative data was tabulated. 2. Prediction equation of posterior from anterior width Posterior= 39.25-0.21*(anterior). The equation explains that when anterior increase posterior decrease and this can quantify as for one-unit increase in anterior there will be 0.21 decrease in posterior width, but this change is not statistically significant (p=0.447). Conclusion: 1. A normative data of maxillary arch dimension and cleft width in UCLP patients was developed and tabulated which will be also be useful as Research data. 2. The Posterior cleft width prediction equation using anterior cleft width, will help in formulating the future treatment plan in required sequence and ease the method of impression making in unilateral Cleft lip and palate patients.
