BackgroundTuberculosis kills five lakh patients in India every year, out of which 7-12 % are with meningeal involvement. Delay in its diagnosis and in initiation of treatment results in poor prognosis and sequlae in up to 25% of cases. The aim of the present study is to look for a simple, rapid, cost effective, non-invasive and fairly specific test in differentiating tubercular etiology from other causes.MethodsForty patients between the age of 6 - 24 months attending hospital with symptoms and signs of meningitis were selected and divided into two groups: tubercular and non-tubercular, depending upon the accepted criteria. CSF was drawn and ADA estimated.ResultsOut of 19 tubercular patients, 18 had CSF ADA at or above the cutoff value while one had below. Out of 21 non-tuberculous patients, two had ADA levels at or above the cutoff value while 19 had below this value. Results of our study indicate that ADA level estimation in CSF is not only of considerable value in the diagnosis of TBM, CSF ADA level 10 U/L as a cutoff value exhibited 94.73% sensitivity and 90.47% specificity in differentiating tuberculous from non-tuberculous meningitis; it also has 90.00% positive predictive value and 95.00% negative predictive value.ConclusionsIt can be concluded that ADA estimation in CSF is not only simple, inexpensive and rapid but also fairly specific method for making a diagnosis of tuberculous etiology in TBM, especially when there is a dilemma of differentiating the tuberculous etiology from non-tuberculous ones. For this reason ADA estimation in TBM may find a place as a routine investigation.KeywordsCerebrospinal fluid; Adenosine deaminase; Tuberculous meningitis

Stroke is the third major cause of death worldwide. Elevated plasma concentration of low density lipoproteins and low plasma concentration of high density lipoprotein concentration are associated with an increased risk of atherosclerosis and coronary heart disease but the relation between serum lipids, and cerebrovascular disease is less clear. The aim of this study was to investigate the reliability and accuracy of serum lipid profile in assessing the prognosis/neurological worsening in patients with ischemic and hemorrhagic cerebrovascular stroke. The subjects in the present study comprised of 101 healthy controls and 150 cerebrovascular stroke patients (including 90 with ischemic stroke and 60 with intracerebral hemorrhagic stroke). In both the groups fasting lipid profile was determined within 72 h of the stroke. A statistically significant association was observed (p \ 0.001) between the parameters of lipid profile of cases and healthy controls, and also with the prognosis of the stroke.

Vascular thrombotic disorders have emerged as a serious threat to our society. Platelet adhesion to fibrinogen, collagen and other platelet activators exposed over the atherosclerotic plaques can trigger platelet signaling events, activate platelets and lead to thrombotic events. Since anticoagulant and thrombolytic treatment strategies are usually associated with serious bleeding complications, preventing platelets adhesion may help to maintain platelets in an inactive state. In this study we tried to find out the effect of Silver nanoparticles, through their interaction with various platelet surface integrins on platelet adhesion on immobilized fibrinogen. Platelets, isolated from anticoagulated human whole blood sample from healthy donors, were suspended in physiological buffer and each sample was divided into four tubes. In three of them 0.05, 0.5, and 5 lM concentrations of Silver nanoparticles were added, fourth tube served as control. Platelet adhesion on immobilized fibrinogen matrices and integrin mediated cell signaling events were studied in all the four samples. In the present study we show that nanosilver prevent platelet adhesion without conferring any lytic effect on them and effectively prevents integrin-mediated platelet responses in a concentration-dependent manner.

Background: There has been frequent researches on liver pathologies and its variables in the world. There is no known research carried on liver in Garhwal region. Uttarakhand is one area where the hill people are more habitual of alcohol abuse and alcoholism is more endemic here. Primary objective was to correlate alcohol intake and its effect on liver function test. Secondary objectives were to screen the patients for abnormal LFTs and to observe and understand changes needed in lifestyle to reduce risk of developing liver disorders.Methods: A cross sectional observational study was conducted on patients in a medical college in north India. The participants above the age of 10 years were included for the study.Results: Out of all the 150 study participants screened, 120 (80%) were detected to have abnormal liver function tests (LFT) (65 females and 55 males). Maximum numbers of participants with abnormal LFT belong to age group of 21-30 yrs. More frequent and higher amount of alcohol consumption was found to adversely affect the liver physiology.Conclusions: The most important risk factor for liver damage is frequent consumption of alcohol in excess of 4 pegs a day for males and 2 for females (One standard drink contains 10 grams of alcohol).
