Abstract
This systematic review and meta-analysis was planned with the objective of evaluating the level of Lactate Dehydrogenase (LDH) in oral submucous fibrosis patients and in controls and comparing them. For this meta-analysis, we searched Google Scholar, PubMed, Scopus, and Directory of Open Access Journals (DOAJ) databases using a search methodology that included combinations of MeSH terms and keywords and included cross-sectional studies to evaluate the levels of LDH in patients with Oral Submucous Fibrosis (OSMF), Oral Squamous Cell Carcinoma (OSCC) and compared it with the controls. The total number of records identified through database searching was 4161 (n). Analysis of the quality of the studies was done using the National Heart, Lungs and Blood Institute (NHLBI) tool for case-control studies. Twelve case-control studies which matched the inclusion criteria were included after the literature search. The meta-analysis was carried out using R Studio (version 4.1.3, 2022; The R Foundation for Statistical Computing, Vienna, Austria). The pooled estimate that has been calculated from the salivary LDH course for OSMF was 15.35% and from the serum LDH course for OSMF was 6.82%. There was a visual observation of the funnel's plot asymmetry suggesting publication bias. After adjusting the publication bias, the t2 values for salivary and serum LDH were 41% and 14.71%, respectively, which was less than 50%, indicating that the meta-analysis was statistically significant. The evaluation of salivary and serum LDH can be a useful method for early diagnosis of OSMF as well as OSCC. To infer that individuals may have OPMD or OSCC, specific values for salivary and serum LDH must be found in further investigations.

Abstract
Ameloblastoma is a benign yet locally aggressive tumor of the jaw bones and is most commonly found in the lower mandibular region. Histologically, it shows benign characteristics. However, ameloblastoma can turn malignant to show a more aggressive clinical course. Carcinoma ex ameloblastoma is an extremely rare malignancy arising from a pre-existing long-standing ameloblastoma or a recurrence of an ameloblastoma. According to the literature search, six to seven cases have so far been documented, and the majority of the lesions had a propensity to metastasize. Here, we present a case of carcinoma ex ameloblastoma implicating a 19-year-old male patient manifesting in the mandible, which arises from pre-existing ameloblastoma.

Abstract
Auto Immune Haemolytic Anaemia (AIHA) is one of the most common types of acquired haemolytic anaemias. Its main cause is auto-antibody mediated rapid destruction of Red Blood Cells (RBCs). Demonstration of a positive Direct Antiglobulin Test also known as Coomb's test, against these autoantibodies is the crucial serological assay in the diagnosis of AIHA. This routinely used test has the disadvantage of low sensitivity and does not detect low levels of red cell auto antibodies leading to false negative results sometimes. Flow cytometry can effectively diagnose such patients with low levels of autoantibodies. This study was carried out in a tertiary care center, where patients with suspected AIHA were studied during 2 years period. Blood samples of suspected patients of AIHA were tested by both Gel Card Test and by Flow-cytometry for detection of RBC bound IgG. A total of 50 patients with suspected diagnosis of AIHA were studied by flow-cytometry as well as by Gel card test for detection of RBC bound IgG. Out of these 50 cases, 41 cases have turned out to be positive and 9 were negative by flow-cytometry. By Gel card test, out of 50 cases, 34 were positive and 16 were negative. Therefore, there were 7 cases which were negative for RBC bound IgG by Gel card test and these were positive by flow-cytometry. Flow-cytometry is a reliable and more sensitive method and can be used as a new routine diagnostic technique for AIHA.

Abstract
INTRODUCTION Hemostatic disorders are often missed in women with bleeding particularly menorrhagia. Preexisting hemostatic disorders are now known as common risk factor for postpartum hemorrhage and prolonged bleeding in puerperium. Females with bleeding complaints constitute an important population referred to hematology clinic. Hence, we aim to evaluate the type and frequency of hemostatic disorders among females presenting with bleeding in a tertiary care hospital and a basic hemostatic laboratory. METHODS Three-year data were retrospectively analyzed for 200 females with various bleeding complaints. Due to resource constraints, a hemostatic workup was done with prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen assay, clot solubility test, mixing studies, specific factor assays, platelet function test, and von Willebrand factor antigen level. RESULTS A total of 200 females were investigated to identify the cause of their bleeding. Thirty-five of 200 (17.5%) females were found with an underlying bleeding disorder. Of these 35 females, 65.7% presented with bleeding from more than 1 site. Most common bleeding manifestation was spontaneous bruising in 18 of 35 (51.4%) patients followed by petechiae (48.6%). Inherited bleeding disorders were noted in majority. The most common inherited bleeding disorder identified was von Willebrand disease (VWD) in 34.3% females. Second most common disorder was Glanzmann's thrombasthenia accounting for 22.8%. Rare coagulation factor deficiency, such as factors VII, X, and XIII deficiencies, was noted. Three cases revealed acquired causes of coagulation defects. CONCLUSION Underlying hemostatic defects should be searched for in women with unexplained bleeding complaints. This will not only help in diagnosis but also in proper management for future hemostatic challenges.

Abstract
Background and objectives: Imatinib mesylate is approved for the treatment of Chronic Myeloid Leukemia (CML). About 20% of patients with CML do not respond to treatment with Imatinib either initially or because of acquired resistance. In addition to mutated BCR-ABL1 kinase, the organic cation transporter1 (OCT1, encoded by SLC22A1) has been considered to contribute to Imatinib resistance in patients with chronic myeloid leukemia (CML). OCT1 has been reported to be the main influx transporter involved in Imatinib uptake into CML cells. To date, only a few studies have been reported on involvement of influx transporters in development of Imatinib resistance. Therefore this study was aimed to determine the expression level of Imatinib uptake transporter (OCT1) in CML patients and to correlate this level with molecular response. Methods: One hundred fifty eight patients on Imatinib were considered for gene expression analysis study for OCT1 gene. Total RNA was extracted from peripheral blood mononuclear cells. Complementary DNAs (cDNAs) were synthesized and Real Time Polymerase Chain Reaction (RQ-PCR) was performed. Results: High OCT1 expression was present in 81 (51.8%) patients and low OCT1 expression was in 77 (48.7%) patients. Low Sokal risk score group have a significantly high OCT1 expression (p=0.048). The rate of molecular response was higher in those with high OCT1 expression than in those with low OCT1 expression (p=0.05). Both event-free survival and median overall survival were significantly shorter in patients with low OCT1 expressions when compared to the patients with high OCT1 expression (p=0.03 and p=0.05). Conclusions: Our findings demonstrated that the mRNA expression level of OCT1 was significantly correlated with molecular response in CML patients. Based on these findings, present study believes that the pre-therapeutic higher expression of OCT1 may help to predict response to imatinib therapy in CML patients.

Abstract
INTRODUCTION Central nervous system (CNS) involvement in acute lymphoblastic leukemia (ALL) is diagnosed traditionally by cytopathology (CP) of the cerebrospinal fluid (CSF). Role of flow cytometry (FC) to diagnose CNS involvement has not been extensively investigated. METHODS We aimed to detect CNS involvement in 42 ALL patients (33 B-ALL, nine T-ALL) at diagnosis by FC and comparing it with CP and to correlate it with known risk factors for CNS disease like Lactate dehydrogenase (LDH). A receiver operating characteristic curve was used to determine the cutoff of LDH to predict CSF involvement. For the analysis of categorical/quantitative variables, Fisher's exact test was used. For the analysis of continuous variables, Mann-Whitney test was used. A P value of <.05 was taken as significant. RESULTS CP and FC were positive in five (11.9%) and 11 patients (26.14%) respectively with FC detecting a significantly higher level of involvement (P=.001). All CP-positive cases were FC positive. A LDH value of >472 U/L had a sensitivity of 61% and specificity of 62.5% for diagnosis of CSF involvement by FC. CONCLUSIONS CSF FC detects CNS disease in ALL patients at diagnosis at a rate double than CP alone and is statistically associated with an elevated LDH level. It should be incorporated in the evaluation of CSF to detect CNS involvement.

Abstract
The etiology of ITP remains unknown but its pathogenesis consists of loss of tolerance to platelet antigens. There is a complex dysregulation of the immune system involving both the B cells and the T cells. Splenectomy is the standard second line option in steroid refractory chronic ITP patients. However, costs of surgery and reluctance for surgery in severely thrombocytopenic patients on part of surgeons are major obstacles in resource limited settings. Rituximab has been used in both the standard doses of 375 mg/m2 and low doses of 100 mg/m2 with similar results. We studied the utility of low dose Rituximab (@100 mg/m2 weekly × 4 doses) in resource limited settings. Overall response, complete response (CR) and partial response (PR) rates were 47.6% (10/21), 33.3% (7/21) and 14.3% (3/21) respectively. Median time to response in patients achieving CR was 75 days (range 45-185 days) while in patients achieving PR it was 105 days (range 45-165 days). However, there was no significant difference between males and females achieving CR or PR. We also observed that patients who had earlier responded to any form of treatment were more likely to respond to Rituximab treatment. The cumulative relapse free survival (RFS) at 13 months was 78%. By giving lower dose, six times less than conventional dosing dose, we have been able to demonstrate cost effectiveness in our study population. We were able to administer all the doses in day care without any major adverse events leading to further cost savings on in-patient care.

Abstract
Peste des Petits Ruminants (PPR) is a transboundary viral disease of small ruminants that causes huge economic losses in Africa, The Middle East and Asia. In Morocco, the first PPR outbreak was notified in 2008. Since then no cases were reported for seven years, probably due to three successive vaccination campaigns during 2008-2011 and close surveillance at the border areas. In June 2015, the disease re-emerged in Morocco, raising questions about the origin of the virus. The PPR virus was confirmed by qRT-PCR and virus was isolated from clinical samples on VeroNectin-4 cells. The disease was experimentally reproduced in Alpine goats using both sheep and goat derived outbreak isolates. Molecular characterization of the 2015 Moroccan PPR isolate confirmed the identity of the virus as lineage IV, closely related to the 2012 Algerian (KP793696) and 2012 Tunisian (KM068121) isolates and significantly distinct from the previous PPRV Morocco 2008 strain (HQ131927). Therefore this study confirms a new incursion of PPR virus in Morocco during 2015 and highlights the urgency of implementation of a common control strategy to combat PPR in Maghreb region in North Africa.

Abstract
A retrospective analysis of clinico-hematologic parameters of 18 factor XIII-deficient patients was carried out. The hematologic tests included activated partial thromboplastin time (APTT), prothrombin time (PT), and clot solubility. Laboratory diagnosis of FXIII deficiency was made where bleeding time, PT, APTT, and thrombin time were normal and the clot solubility test result with 5M urea was positive. Factor XIII level with family screening was performed using commercially available kits. History of prolonged bleeding from the umbilical stump was present in four (22.2%) patients. The most common site of bleeding was the skin (11 of 18 patients). Three patients were given prophylaxis (FFP in two, factor XIII in one). A high prevalence of recurrent abortion in female pa tients with FXIII deficiency (two of the three patients in this study) was observed.

Abstract
Fifty-three patients of thalassemia intermedia and 40 controls were studied for clinical evidence of thrombosis and laboratory evidence of hypercoagulable state. Thrombotic episodes were detected in 5 (9.4%) patients. Two of these 5 patients with thrombosis were splenectomized. Laboratory evaluation showed presence of thrombocytosis in 8 (15%), 5 of these were splenectomized. Platelet hyperaggregation was detected in 12 (22.2%) patients. Although rate of aggregation was slow in 7 (13.2%) patients, degree of aggregation was normal in these 7 patients and platelet hypoaggregation was not detected in any patient. Level of coagulation inhibitors protein C and protein S, and antithrombin III were decreased in 31 (58.4%) patients. There was no correlation between low level of protein C and protein S with hepatic dysfunction and iron overload. Antithrombin III level was decreased only in 8 (15%) patients. There was a statistically significant association between the lower level of this inhibitor and hepatic dysfunction. In conclusion, this study provides evidence for the existence of a chronic hypercoagulable state in patients with β thalassemia intermedia, and suggests that expression of a procoagulant surface by thalassemia intermedia red blood cells may be the major underlying factor giving rise to platelet and coagulation inhibitor abnormalities in these patients. These alterations are not related to iron overload or hepatic dysfunction.

Abstract
Peste des petits ruminants virus causes a highly infectious disease of small ruminants that is endemic across Africa, the Middle East and large regions of Asia. The virus is considered to be a major obstacle to the development of sustainable agriculture across the developing world and has recently been targeted by the World Organisation for Animal Health (OIE) and the Food and Agriculture Organisation (FAO) for eradication with the aim of global elimination of the disease by 2030. Fundamentally, the vaccines required to successfully achieve this goal are currently available, but the availability of novel vaccine preparations to also fulfill the requisite for differentiation between infected and vaccinated animals (DIVA) may reduce the time taken and the financial costs of serological surveillance in the later stages of any eradication campaign. Here, we overview what is currently known about the virus, with reference to its origin, updated global circulation, molecular evolution, diagnostic tools and vaccines currently available to combat the disease. Further, we comment on recent developments in our knowledge of various recombinant vaccines and on the potential for the development of novel multivalent vaccines for small ruminants.

Abstract
Peste des petits ruminants (PPR) is an economically important disease of small ruminants with a rapidly expanding geographical distribution. Peste des petits ruminants virus may manifest in a variety of ways with disease ranging from acute to subclinical. We investigated the exposure of large ruminants to PPRV in areas where the virus is endemic in the small ruminant population by assessing the serological status of groups of animals. This study focused on the Punjab province of Pakistan as an area where the virus is endemic and where mixed farming practices occur enabling close interactions between small and large ruminant populations. An overall PPR seropositivity was detected in 10.0% of cattle and 14.16% of buffaloes. Following an assessment of serological profiles in large ruminants within different age groups, a maximum seroprevalence was observed in cattle (17.5%) and buffaloes (22.5%) over 2 years of age indicating the potential utility of sampling large ruminant populations for PPR serosurveillance. The large ruminants sampled between one and two years of age had similar levels of seropositivity within populations with 11.2% and 16.2% of animals being seropositive, respectively. Current PPR vaccination strategies do not enable the differentiation between infected and vaccinated small ruminants, and as such, the serological surveillance of sheep and goats is of little value. When considering eradication programmes for PPRV, this factor is of great significance. However, where large and small ruminants are farmed together, serological surveillance of large ruminants may provide a snapshot of virus infection within populations where mild disease is present or where small ruminants are regularly vaccinated.

Abstract
BACKGROUND The incidence of aplastic anaemia (AA) is higher in Asia than in the West. The precise incidence of AA in India is not known due to lack of epidemiological study. 20-40% of pancytopenic patients in referral centres are of aplastic anaemia. PATIENTS AND METHODS This was an analysis of 1501 patients diagnosed with aplastic anaemia over a period of seven and half years (January 2007- June 2014) attending the Aplastic clinic of department of haematology of All India Institute of Medical Sciences, New Delhi. The details regarding medical history, physical examination, complete blood count, bone marrow aspirate and biopsy, treatment received, were retrieved. Inherited bone marrow failure was screened in patients below 35 years. Treatment response was analysed for various treatment modalities. RESULTS 1501 patients of AA from 20 different states of India were analysed. The bulk of patients were from Uttar Pradesh (28.7%), Bihar (23.6%), Delhi/NCR (20%) and Haryana (7%).The average number of new aplastic anaemia patients enrolled per year 214 (range: 101 -263). The median age at presentation was 25 years (range 2-83),with M;F - 2.3:1. Severity of AA revealed: severe (SAA): 75%, very severe (VSAA): 15%, non-severe (NSAA): 10%. Inherited bone marrow failure syndromes constituted 5% (75 patients) of all aplastic anaemia patients. The most common clinical presentations were pallor (97%), bleeding manifestations (69.6%) and fever (54%). The haematological parameters showed: median level of haemoglobin level: 5.9 gm/dL, WBC: 2700/mm3, ANC: 380/mm3, platelet: 1 0000/mm3. PNH clone was present in 13.5% of patients. 107 patients (7%) were lost to follow up or expired before any treatment was initiated. Only 69 patients (4.5%) received treatment with HLA-matched sibling stem cell transplantation and another 232 (15.5%) patients received ATG plus cyclosporine as immunosuppressive therapy. Seven hundred thirteenpatients (47.5%) received cyclosporine. The overall response to various treatment modalities was: HLA matched sibling haematopoietic stem cell transplant: 75.3%, Anti-thymocyte globulin plus cyclosporine: 58.7%, cyclosporine plus androgen: 45.6%, cyclosporine alone: 32.2%. CONCLUSION Management of AA is a real challenge in developing countries.This is one of the largest case series from a single centre from India. It is our endeavour to reduce the detrimental outcome by increasing awareness among patients and referring physicians to reduce the delay between diagnosis and treatment.

Abstract
Isolates of peste des petits ruminants virus (PPRV) can be segregated genetically into four lineages. For decades, lineages I-III have been reported across Africa whilst lineage IV has predominantly circulated across Asia. However, the lineage distribution is currently changing in Africa. Importantly, full genome sequence data for African field isolates have been lacking. Here, we announce the first complete genome sequence of a field isolate of peste des petits ruminants virus (PPRV) from East Africa. This isolate was derived from the intestine of a goat suffering from severe clinical disease during the 2010 outbreak in Ethiopia. The full genome sequence of this isolate, PPRV Ethiopia/2010, clusters genetically with other lineage IV isolates of PPRV, sharing high levels of sequence identity across the genome. Further, we have carried out a phylogenetic analysis of all of the available African partial N gene and F gene PPRV sequences to investigate the epidemiology of PPRV with a focus on the emergence of different lineages of PPRV in Africa.

Abstract
Factor VIII (FVIII) inhibitors present major clinical challenge as a complication of hemophilia A in patients on treatment with FVIII concentrates and as acquired autoantibodies in patients without hemophilia A. We aimed to study the prevalence of FVIII inhibitors in Indian settings, risk factors involved in early development of inhibitors in patients with hemophilia, differences in their clinical behavior, and approach to treatment, in comparison to patients with acquired hemophilia. The overall prevalence of FVIII inhibitors in patients with severe hemophilia A was found to be 22.3%. Two cases of acquired hemophilia were reported. Due to heterogeneity of our study population, cases have been discussed individually. We observed that the early development of FVIII inhibitors in patients with hemophilia A is dependent upon an interplay of several risk factors that need to be studied in a multivariable analysis to bring out significant correlation with response to treatment. Also, they differ from patients without hemophilia A entirely in terms of presentation and management.

Abstract
INTRODUCTION The inactivation of suppressor of cytokine signaling SOCS-1, a negative regulator of cytokine pathways, by hypermethylation was shown in hematological malignancies including Myelsplastic Syndromes. So far, its prognostic relevance in myelodysplastic syndromes (MDS) patients has not been understood. METHODS Methylation status of SOCS-1 gene was analyzed in series of 100 patients using methylation-specific PCR (MS-PCR) and correlated with disease severity, progression, and survival by comparing prognostic factors such as hematological, clinical, and cytogenetics. RESULTS Of the total of 100 MDS patients analyzed, methylation of SOCS1 gene was found in 53% patients. Also, the frequency of patients with poor and intermediate cytogenetics was observed significantly high in methylated group (P < 0.001). Moreover, the patients with methylated SOCS-1 gene had significantly more frequent disease progression as compared to the patients with unmethylated SOCS-1 gene (P < 0.006). Both progression-free survival and median overall survival were significantly shorter in patients with methylated SOCS-1 gene when compared to the patients with unmethylated SOCS-1 gene (P = 0.006 & P = 0.001, respectively). CONCLUSION This study for the first time showed that the mathylation of SOCS-1 gene plays an important role in the disease progression and is associated with poor survival especially among the high-risk patients. This may be due to high association between SOCS1 methylation and higher risk subtypes of MDS (such as RAEB) in this study.

Abstract
The current measures to control foot-and-mouth disease (FMD) include vaccination, movement control and slaughter of infected or susceptible animals. One of the difficulties in controlling FMD by vaccination arises due to the substantial diversity found among the seven serotypes of FMD virus (FMDV) and the strains within these serotypes. Therefore, vaccination using a single vaccine strain may not fully cross-protect against all strains within that serotype, and therefore selection of appropriate vaccines requires serological comparison of the field virus and potential vaccine viruses using relationship coefficients (r1 values). Limitations of this approach are that antigenic relationships among field viruses are not addressed, as comparisons are only with potential vaccine virus. Furthermore, inherent variation among vaccine sera may impair reproducibility of one-way relationship scores. Here, we used antigenic cartography to quantify and visualize the antigenic relationships among FMD serotype A viruses, aiming to improve the understanding of FMDV antigenic evolution and the scope and reliability of vaccine matching. Our results suggest that predicting antigenic difference using genetic sequence alone or by geographical location is not currently reliable. We found co-circulating lineages in one region that were genetically similar but antigenically distinct. Nevertheless, by comparing antigenic distances measured from the antigenic maps with the full capsid (P1) sequence, we identified a specific amino acid substitution associated with an antigenic mismatch among field viruses and a commonly used prototype vaccine strain, A22/IRQ/24/64.

Abstract
Chronic lymphocytic leukemia (CLL) is the most common form of leukemia in elderly people. The clinico-hematological profile and treatment outcome of patients with CLL were assessed using retrospective case record analysis over 11 years. There were 95 (75 males: 20 females) patients with a median age of 61 years. Thirty patients were aged 55 years or less (young CLL patients) and 65 were more than 55 years of age (elder CLL patients). Sixty percent patients had non-specific complaints, such as weakness, cough and indigestion. Twenty-six (27%) patients had pallor and 24 (25%) had fever as initial presenting manifestation. Bleeding manifestations were seen in 7 patients. Seven patients were diagnosed incidentally. Lymphadenopathy, splenomegaly and hepatomegaly were seen in 52 (55%), 63 (66%) and 60 (63%) patients, respectively. The median white blood cell count and absolute lymphocyte counts were 70,600 and 51,490/mul, respectively. Three patients had autoimmune hemolytic anemia. Twenty-five patients (26%) had anemia with hemoglobin < 11 g/dl and thrombocytopenia with platelet count 100 x 10(3)/mm(3) was seen in 17 (18%). Interstitial nodular, mixed and diffuse bone marrow (BM) involvement was seen in 10.2, 67.3, 6.1 and 16.3% cases, respectively. Eighteen (60%) young patients and 35 (54%) older patients required treatment with chlorambucil. The mean time from initial diagnosis to treatment was 4.6 +/- 10.7 months. None of our patient attained complete response. Six patients obtained partial response. Median duration of chlorambucil was 7 months (1-86 months). Forty-six patients had stable disease. Three patients died. Median survival of study group was 4 years (8 months-13 years). In older CLL it was 4 years (8 months-11 years) and in young patients, survival duration was 5.5 years (1-13 years).

Abstract
Thalassemia intermedia patients show variable phenotypes. Hydroxyurea (HU) may benefit some of the thalassemia intermedia cases (1), however, the parameters influencing the response to HU have not been reported. In this study, the molecular parameters, alpha-globin and beta-globin genotype and the Xmn I polymorphism, were correlated with the HU response. Twenty patients with thalassemia intermedia were given HU (10-20 mg/kg) and responses were evaluated over a one year period. Twelve patients (60%) showed a good response to therapy with a significant increase in Hb and HbF levels and with elimination of the transfusion requirement in four patients. Four out of the twelve (33%) patients were positive for -alpha(3.7) deletions whereas none of the 8 non-responders were positive for alpha deletions. One each of the responders and non-responders were positive for alpha alpha alpha(anti-3.7) triplication. Three (25%) responsive and one non-responsive patients were homozygous for the IVS1-1 (G-->T) mutation. Three of the responsive patients with alpha deletions were also homozygous positive for Xmn I polymorphism. Thus, in addition to acting in synergy with the XmnI polymorphism, alpha deletions may be an independent factor predicting good response to HU in thalassemia intermedia, although this needs to be confirmation in larger studies.

Abstract
We describe the clinical, hematological and histomorphological features in children of primary myelodysplastic syndrome (MDS) seen at the All India Institute of Medical Sciences over three years (Jan 2001-Jan 2004). Twenty-one patients of primary MDS aged 17 year or less were classified using the latest proposed WHO classification for Pediatric MDS. The median age was 9 years with male predominance (80%). Pallor was present in all the cases while fever and bleeding diathesis was present in more than 50% of the cases. Morphological assessment of the peripheral blood showed macrocytosis in 50%, pancytopenia in 15% and blast cells in 45% of cases. A complete analysis of clinical features in conjunction with the bone marrow profile revealed 8 cases of refractory cytopenia (RC), 3 cases of refractory anemia with excess blasts (RAEB), 5 cases of refractory anemia with excess blasts in transformation (RAEB-T), 4 cases of Juvenile myelomonocytic leukemia (JMML) and a solitary cases of acute myeloid leukemia (AML) in Downs syndrome. These children were followed up from 1-36 months (mean 15 months). Three patients of RAEB-T progressed to AML within 3-4 months. RC had the best prognosis and all are alive and under regular follow up. The solitary case of AML of Downs syndrome died 1.5 months after initial diagnosis. All 3 cases of RAEB are under regular follow-up and doing well. Three cases of RAEB-T died (all had progressed to AML); the remaining 2 cases were lost to follow up. Of the 4 cases of JMML 1 died within 6 months of diagnosis; the other 3 cases are under regular follow up of whom 1 has a progressively increasing blast count. We conclude that the latest proposed WHO classification for Pediatric MDS can be successfully applied to all cases of primary MDS.

Abstract
Five neutralizing antigenic sites have been identified on the surface of serotype O foot-and-mouth disease virus (FMDV). A set of mAb neutralization-escape mutant viruses was used for the first time to evaluate the relative use of known binding sites by polyclonal antibodies from three target species: cattle, sheep and pigs. Antibodies to all five neutralizing antigenic sites were detected in all three species, with most antibodies directed against antigenic site 2, followed by antigenic site 1. In 76 % of cattle, 65 % of sheep and 58 % of pigs, most antibodies were directed against site 2. Antibodies specific to antigenic sites 3, 4 and 5 were found to be minor constituents in the sera of each of the target species. This implies that antigenic site 2 is a dominant neutralization immunogenic site in serotype O FMDV and may therefore be a good candidate for designing novel vaccines.

Abstract
This study was conducted in 20 children (16 males) (mean age 9.2 +/- 4.34y) with immune thrombocytopenic purpura (ITP) to assess the response to anti-D immunoglobulin. Six patients had newly diagnosed ITP, 6 had persistent ITP and 8 had chronic ITP. The overall response rate was 70% (14/20). The median time to response was 3 days (1-13 days). Response to anti-D was not related to age, sex, severity of bleeding, platelet counts at presentation, ABO blood group, or prior steroid or IVIG response.

Abstract
Oral high dose dexamethasone (HDD) was given as a single daily dose for four consecutive days, every 14 days for four courses. Twenty-nine patients were enrolled. Overall 20 patients (69%) responded: complete response (CR) was achieved in 16 (55%) patients, partial response (PR) in three (10%) patients and MR in one (3%) patient. In acute immune thrombocytopenic purpura (ITP) response rates after the first, second, third and fourth cycles were as follows: 64% (9/14), 64% (9/14), 79% (11/14), and 85.7% (12/14), respectively. In chronic ITP, overall response rates after the first, second, third and fourth cycles were as follows: 33% (5/15), 40% (6/15), 53% (8/15) and 53% (8/15) respectively. The median time to response was 14 days (4-42 days). Twelve out of 20 patients (5/12 acute ITP and 7/8 chronic ITP) relapsed; median relapse free survival till last follow-up in the remaining eight patients was 130 days (65-365 days).

Abstract
e22231 Background: Chromosomal abnormalities and molecular detection has potential importance for diagnosis and prognosis of MDS, although the mechanisms underlying the development of MDS and their progressive evolution to AML are still largely unknown. Since, no studies have been reported from India on the prevalence of N-RAS, K- RAS point mutation in codon 12 and FLT3-ITD mutations in patients with MDS, we undertook this study. Methods: DNA and RNA were extracted from bone marrow /peripheral blood. Using RT-PCR the patients were screened for length mutations in FLT3 gene. PCR-RFLP and nested PCR-RFLP were used for the detection of point mutation in codon 12 of N-RAS and K-RAS. Results: A total of 53 patients (median age 39 yrs, range 9–78yrs; M: F 2:1; median TLC-3.9×109/l, range 0.8–116 ×109/l Median platelet count- 87 ×109/l, range 1–349 ×109/l, Median hemoglobin -6.8 g/dl, range 2.7- 16.1 g/dl, were studied. One out of 53 patients (2%) was found positive for N-RAS and four patients were positive for K-RAS (8%) mutation. FLT3-ITD mutation was studied in 47 patients; all the patients were found negative. The mean observation of all the patients was 30 months and the median overall survival was 28 months. Nine patients died during follow up. The presence of N-RAS codon 12 mutation was associated with the poor survival. FLT3-ITD mutation was not observed in any of our cases, which is in contrast to 3% reported from the West. Conclusions: Thus, it appears that the RAS and FLT3 mutations are uncommon in MDS patients in India. No significant financial relationships to disclose.

Abstract
We retrospectively analyzed 750 patients with ITP for development of intracranial hemorrhage (ICH). Seventeen cases with age range of 10 months to 18 years were studied. Ten patients were of acute ITP and seven had chronic ITP. Nine patients developed ICH one month after the onset of ITP and five patients had ICH on presentation. ICH was precipitated by trauma in four patients and possibly the use of NSAIDs in one patient. Median platelets counts at the time of ICH were 12 x 10(9)/L (range 2-50 x 10(9)/L). Most patients were treated with corticosteroids. Four patients (24%) died due to ICH.

Abstract
Mycobacterium tuberculosis (MT) is a serious, but rare infectious complication after allogeneic bone marrow transplantation (BMT). We describe a case of fatal sepsis due to MT and Aspergillus flavus after allogeneic BMT for Aplastic Anemia. The diagnosis was made on bone marrow biopsy and asitic fluid culture. Broadspectrum antituberculous and Amphotericin B therapy was started immediately after diagnosis. The patient developed severe hypoxia and finally died of multi-organ failure. Rapid progression of mycobacterial infection as well as fungal infection should be considered in patients post BMT with unexplained fever, particularly in patients from endemic areas.
