Epidemiology of knee osteoarthritis in India and related factors.

Abstract: Background: Among the chronic rheumatic diseases, hip and knee osteoarthritis (OA) is the most prevalent and is a leading cause of pain and disability in most countries worldwide. Its prevalence increases with age and generally affects women more frequently than men. OA is strongly associated with aging and heavy physical occupational activity, a required livelihood for many people living in rural communities in developing countries. Determining region-specific OA prevalence and risk factor profiles will provide important information for planning future cost effective preventive strategies and health care services. Materials and Methods: The study was a community based cross sectional study to find out the prevalence of primary knee OA in India which has a population of 1.252 billion. The study was done across five sites in India. Each site was further divided into big city, small city, town, and village. The total sample size was 5000 subjects. Tools consisted of a structured questionnaire and plain skiagrams for confirmation of OA. Diagnosis was done using Kellgren and Lawrence scale for osteoarthritis. Results: Overall prevalence of knee OA was found to be 28.7%. The associated factors were found to be female gender (prevalence of 31.6%) (P = 0.007), obesity (P = 0.04), age (P = 0.001) and sedentary work (P = 0.001). Conclusions: There is scarcity of studies done in India which has varied socio geographical background and communities. We conducted this study for analyzing the current prevalence of OA in different locations. This study has evidenced a large percentage of population as borderline OA; therefore, it depends mainly on the prevention of modifiable risk factors to preserve at ease movement in elderly population through awareness programs.

Role of inferior vena cava diameter in assessment of volume status: a meta-analysis.

Abstract: Background and Objective Hypovolemic shock is an important cause of death in the emergency department (ED). We sought to conduct a meta-analysis to quantify existing evidence on sonographic measurement of inferior vena cava (IVC) diameter in assessing of volume status adult ED patients. Methods A search of 5 major databases of biomedical publication, EMBASE, Ovid Medline, evidence-based medicine (EBM) Reviews, Scopus, and Web of Knowledge, was performed in first week of March 2011. Studies meeting the following criteria were included: (1) prospectively conducted, (2) measured IVC diameter using ultrasonography, (3) inpatients under spontaneous ventilation, and (4) reported IVC diameter measurement with volume status or shock. Article search, study quality assessment, and data extraction were done independently and in duplicate. Mean difference in IVC diameter was calculated using RevMan version 5.5 (Cochrane collaboration). Results A total of 5 studies qualified for study eligibility from 4 different countries, 3 being case-control and 2 before-and-after design, studying 86 cases and 189 controls. Maximal IVC diameter was significantly lower in hypovolemic status compared with euvolemic status; mean difference (95% confidence interval) was 6.3 mm (6.0-6.5 mm). None of the studies blinded interpreters for volume status of participants. Conclusion Moderate level of evidence suggests that the IVC diameter is consistently low in hypovolemic status when compared with euvolemic. Further blinded studies are needed before it could be used in the ED with confidence.

Renal failure in asphyxiated neonates.

Abstract: A prospective case controlled study was conducted in the NICU of a tertiary level referral teaching hospital to determine the incidence of renal failure in asphyxiated neonates and to correlate severity and type of renal failure with Apgar score and hypoxic ischemic encephalopathy (HIE) grading of the neonates. Ninety-eight neonates were enrolled 70 asphyxiated babies and 28 healthy controls. Renal functions were assessed using urinary output, urine microscopy, biochemical parameters and sonographic findings. Babies having renal failure were managed on a protocolised plan and followed up till 6 months of age to detect any residual impairment. Blood urea and serum creatinine were significantly higher in asphyxiated babies compared to the control group. Biochemical derangements correlated well with HIE staging and Apgar scores. There was no significant difference in urine output in the control and the study group as significant oliguria was seen in only 7 of the 70 asphyxiated babies and the output did not correlate with severity of asphyxia. Serum sodium level and fractional excretion of sodium showed significantly different values in the asphyxiated babies compared to control. Of the 70 asphyxiated babies 33 (47.1 %) had renal failure, which was of the non-oliguric type in 78 % cases and oliguric type in 22 % cases. Sonographic abnormalities were seen more often in oliguric babies and was associated with a bad prognosis. Renal parameters normalized in all neonates by 6 months of age. Mortality was higher in babies with oliguric renal failure. We conclude that renal failure is a significant problem in asphyxiated neonates with majority of babies having nonoliguric failure. Severity of renal function abnormality correlates well with degree of asphyxia. Oliguria, hyponatremia and abnormal sonographic scan are bad prognostic signs in renal failure secondary to birth asphyxia.

Comparison of seropositivity of HIV, HBV, HCV and syphilis in replacement and voluntary blood donors in western India.

Abstract: A 5 year retrospective study from June, 1994 to May, 1999 was conducted at Zonal Blood Transfusion Centre, Umaid Hospital and Department of Pathology, Dr. SN Medical College and Associated Group of Hospitals, Jodhpur (Rajastha, Western India. Donors were evaluated for seroprevalence of HIV, HBV, HCV and Syphilis. A Total 46,957 donors were tested, out of which 42,291 (90.1%) were replacement donors and 4666 (9.0%) were voluntary donors. The incidence of HIV was 0.44% in total donors, more in replacement (0.461%) as compare to voluntary (0.279%). The seroprevalence of HBV in total donor was 3.44%. The replacement donors had high incidence (3.52%) as compared to voluntary donors (2.57%). The incidence of HCV seropositivity was 0.285% (5 month data), all were replacement donors (0.328%). The seroprevalence of VDRL in total donor was 0.22%, more in replacement donor (0.239%) as compare to voluntary donors (0.129%). Hence forth, it has been observed that voluntary blood donation is more safe and advocated as compare to replacement donation, as high incidence of HIV, HBV, HCV and Syphilis are observed in replacement donors.
