Eosinophil Count: Parameter to Assess the Psychological Stress

Human body is endowed with an enormous capacity to cope up with stress. Body’s entire machinery work together to achieve the goal of maintaining the homeostasis. Stressful situations have also become a part of life and both physical and psychological stress are subjected to body response in different ways.Stress is defined as nonspecific response of the body to any demand. Most of the time such stress is psychological one. Aims & Objectives: This study was conducted to see the effect of psychological stress in young students, to evaluate the magnitude of stress under different grades and to identify the students more vulnerable to stress. Methods: The present study was conducted on first year students of Medical College in Meerut. Pulse rate and Eosinophil count were measured of all the students during various periods. Results: Pulse rate was increased significantly in all the subjects of either sex before the examination and Eosinophil count was decreased significantly in all the subjects of either sex. Conclusion: In our study a compare of eosinophil count was made among the students in various phase of psychological stress. All the changes in stress occur probably due to stimulation of sympatho-adrenanl activation via hypothalamo-pituitary-adrenal axis (HPA axis). We must focus on stress-free environment in schools and colleges.

Challenges of conducting clinical trials in Asia

Unlike North America and European Union (EU), Asian continent appears to be an ideal destination for conducting cost-effective clinical trials utilizing the pool of treatment naïve subjects. With a population approaching 4.5 billion, recruitment of subjects can be done without a fear of limited patient pool across Asia. The burden of infectious and chronic diseases is also higher in Asian countries. The emerging clinical trial markets particularly China, South Korea, and Taiwan offers genetic diversity in population group, thus promoting the quality and generalizability of clinical trial’s data. Nonetheless, several challenges also exist for the Western sponsors in majority of the Asian countries; regulatory, operational and infrastructural challenges are atthe forefront. Challenges under the heads regulatory, operational, infrastructural, language and cultural, ethics, and future challenges have been discussed. SWOT analysis of Asian clinical trial’s market exhibits enormous opportunities for study sponsorswith manageable threats.

Long term clinical outcomes of adult hematolymphoid malignancies treated at Tata Memorial Hospital: An institutional audit

Introduction: There is paucity of data from India about the outcomes of patients with various hematological malignancies. Since its formation in 2009, the adult hematolymphoid disease management group of the Tata Memorial Centre is dedicated to the treatment of hematological malignancies alone. In this report, we present the outcomes of patients treated at our centre over a 5 year period for various haematological malignancies in both transplant and non-transplant setting. Methods: This is a retrospective analysis of all patients registered in adult hematolymphoid disease management group between 1st January 2010 to 31st December 2014. Patients not treated at our centre were excluded from survival analysis. The cut off date for survival analysis was 31st January 2016. Results: Overall, 1869, 3633 and 544 patients with acute leukemias, various lymphomas and myeloma respectively were registered at our centre from 1st January 2010 to 31st December 2014. Of these, 1178 (63%), 3091 (85%) and 454 (83%) respectively received treatment at our centre. The cumulative probability of 5 year overall survival for patients with acute leukemias, Hodgkin's lymphoma, non-Hodgkin lymphoma and myeloma treated at our centre is 40%, 85%, 78% and 40% respectively. Four hundred and fifteen stem cell transplants were done between 14th November 2007 to 31st December 2014 with 46% being allogeneic and 54% being autologous. The 5 year overall survival of patients with allogenic and autologous transplant was 52% and 63% respectively. Conclusions: This is the largest single centre data on outcomes of various haematological malignancies from India. This real world data identifies areas which need further attention to improve outcomes.

Comparative Study of Effect of Mitomycin-C and Merocel Packing on Ostial Patency in Primary Endoscopic Dacryocystorhinostomy.

Background: To compare the post operative ostial patency at the rhinostomy site in the patients undergoing the primary endoscopic dacryocystorhinostomy, using Mitomycin-C application and Merocel packing. Methods: The patients visiting the Otorhinolaryngology out patients department at the tertiary referral hospital were included in this study. The study was prospective in nature and comprised of 50 patients suffering from primary dacryocystitis. Endonasal endoscopic dacryocystorhinostomy was done in the patients suffering from the chronic dacryocystitis with postsaccular obstruction of lacrimal system. The patients were divided in two equal groups containing 25 patients in each group. In first group (Group- A) Mitomycin-C (0.5 mg/ml for 15 min) was locally applied at the rhinostomy site and nasal cavity was packed with bactigras after the surgery, whereas in the second group, nasal cavity was packed with Merocel after reposition of the flap without application of any drug. Follow up was done every week in the first month, then monthly till the six months after the surgery. The post operative results were compared in terms of ostial patency at the rhinostomy site at one month, three months and six months of follow up. The surgical technique used remained same throughout the period of study. Results: The post operative ostial patency of rhinostomy stoma was better in the group of the patients undergoing application of Mytomycin-C at the rhinostomy site as compared to the packing of the nasal cavity with Merocel. The difference between both the groups was statistically significant. The rhinostomy created was free from synachiae and granulation tissue formation on follow up examination in the group of the patients having application of Mitomycin-C at the time of surgery. Ultimately the ostial patency was better in the patients having application of Mitomycin-C. Conclusion: Mitomycin-C has statistically significant beneficial effect in the maintenance of ostial patency after primary endonasal endoscopic dacryocystorhinostomy as compared to the merocel packing alone after the surgery.

Formulation design and evaluation of Cefuroxime axetil 125 mg immediate release tablets using different concentration of sodium lauryl sulphate as solubility enhancer

Cefuroxime axetil immediate release tablets were formulated by direct compression method with different percentages of sodium lauryl sulphate (SLS) such as 0.5, 1.0, 1.5 and also without SLS. Resulting batches of tablets were evaluated by both pharmacopeial and non-pharmacopeial methods to ascertain the physico-mechanical properties. Dissolution test were carried out in different medium like 0.07 M HCl, distilled water, 0.1M HCl of pH 1.2 and phosphate buffers at pH 4.5 and 6.8 to observe the drug release against the respective concentration of SLS used. Later, test formulations were compared by f1 (dissimilarity) and f2 (similarity) factors using a reference brand of cefuroxime axetil. Significant differences (p<0.05) in dissolution rate were recorded with the change in concentration of SLS in different media. Test formulation T3 containing 1% SLS was found to be best optimized formulation based on assay, disintegration, dissolution and similarity and dissimilarity factors.

Formularam-se comprimidos de liberação imediata à base de cefuroxima axetil, pelo método de compressão direta, com diferentes percentagens de lauril sulfato de sódio (LSS), tais como 0,5, 1,0, 1,5, e também sem SLS. Os lotes resultantes dos comprimidos foram avaliados por ambos os métodos da farmacopeia e não farmacopeicos para determinar as propriedades físico-mecânicas. O teste de dissolução foi realizado em meios diferentes, como HCl 0,07 M, água destilada, HCl 0,1 M com pH 1,2 e os tampões fosfato (pH 4,5 e 6,8) para observar a liberação do fármaco contra a correspondente concentração de LSS utilizado. Em seguida, as formulações de teste foram comparadas por fatores f1 (dissimilaridade) e f2 (similaridade), utilizando uma marca de referência de cefuroxima axetil. Diferenças significativas (p<0,05) na taxa de dissolução foram registradas com a mudança na concentração de LSS em diferentes meios de dissolução. A formulação T3 contendo LSS a 1% foi considerada a melhor formulação otimizada com base nos ensaios de desintegração, dissolução e fatores de semelhança e dissimilaridade.

Haematological & molecular profile of acute myelogenous leukaemia in India.

Background & objectives: Recurrent balanced translocations are generally recognized to be a major parameter for prognostication in acute myeloid leukaemia (AML). The chromosomal translocation t(15;17) results in PML/RARα fusion gene, t(8;21) results in AML1/ETO fusion gene and Inv 16 generates CBFβ/MYH11 fusion gene. Patients with these mutations have a good prognosis unlike abnormalities in chromosome 5 or 7 or FLT3 genes. Therefore, we screened the AmL patients for known specific genetic abnormalities that could lead to more definitive prognoses. Methods: A total of 113 AML patients were evaluated at diagnosis based on routine morphology and cytochemistry and classified according to the WHO criteria. The distribution of AML subtypes was M1(1), M2(32), M3(57), M4(14), M5(1), M6(1) and seven cases where morphological subtype could not be classified. RT-PCR was performed to identify PML/RARα, AML1/ETO, CBFβ/MYH11 and FLT3 internal tandem duplication (ITD). Results: Of the 57 patients with M3 subtype, 55 had the PML-RARα fusion transcript. The prevalence of bcr3 (short isoform) was higher (62%) than that of bcr1 (long isoform) (38%) and no correlation was found with age, sex or white blood cell count. FLT3 internal tandem duplication (ITD) mutations were more frequent in patients with APL than in other AML subtypes (17.5 vs. 8.9%), the frequency greater in patients with bcr3 isoform (70%) than in those with in bcr1 isoform (30%). Patients with FLT3/ITD mutations had a significantly higher median white cell count than those without these mutations (55 x 109/l vs. 6.3 x 109/l; P<0.001). More patients with FLT3/ITD mutations died early (53%) than those without these mutations (16%) (P<0.01). AML1-ETO fusion transcript was detected in 16 of 56 patients with no correlation with clinical or haematological parameters. Interpretation & conclusion: The results of the present study showed presence of bcr3 (short isoform) higher than bcr1 (long isoform). FLT3 internal tandem duplication (ITD) mutation was predominant in acute promyelocytic leukaemia patients with bcr3 isoform. Thus, patients with APL who have FLT3 mutation appear to have a poorer prognosis. Therefore, rapid identification of specific translocations at diagnosis is important for prognostic purposes and their detection should be incorporated into routine assessment.

AML1-ETO positive AML: first report from India.

Translocation (8;21) is associated with few typical morphological features and favorable prognosis. All patients of AML and MDS with increased blasts (N = 35) according to FAB criteria, presenting (between Jan 2004 to June 2005) to the Department of Hematology, AIIMS were studied. RT-PCR was done for the AML1-ETO fusion transcript in all cases. Overall incidence of AML1-ETO was 28.57% and no correlation was found between AML1-ETO positivity and clinical or hematological parameters except for a direct correlation with absolute blast count (ABC) (a lower ABC in the AML1-ETO positive cases). Interestingly, 1/3 MDS cases were positive for the same fusion transcript and thus, it appears worthwhile to look for AML1-ETO in all cases of MDS with increased blasts. Objective morphological evaluation using a scoring system based on morphological features was not helpful in predicting positivity for AML1-ETO. The effect of this translocation on long-term survival could not be determined by the present study.
