Splenic Angiosarcoma Presenting With Jaundice, Ascites and Bone Marrow Fibrosis

A middle aged chronic alcoholic presented with deep jaundice, markedly enlarged and tender spleen with leukoerythroblastic blood picture and bone marrow biopsy showing mild fibrosis. He was tested negative for HIV, hepatitis B and C viruses. Besides very high serum bilirubin, alkaline phosphatase was raised four times the normal value. Contrast enhanced CT showed enlarged spleen and liver with multiple heterogenous lesions in spleen and tiny hypo-dense lesions in liver. In hospital, he developed haemolytic uraemic syndrome and succumed to his illness. At autopsy spleen weighed 5200 gms and variegated in appearance due to large areas of necrosis and whitish tumour nodules. Histology revealed morphology of an angiosarcoma. Liver was also infiltrated by the tumour mainly in and around portal tract areas

A Case Series Highlighting the Relative Frequencies of the Common, Uncommon and Atypical/Unusual Hematological Findings on Bone Marrow Examination in Cases of Visceral Leishmaniasis

Introduction: Bone marrow aspiration and biopsy still remains as one of the vital tests for confirmation of diagnosis of visceral Leishmaniasis. The aim of the present study is to assess the relative frequency of common, uncommon and atypical hematological findings in cases of Visceral Leishmaniasis. Materials & Methods: A total of 16 cases of Leishmaniasis diagnosed on Bone marrow examination over a period of two years (2008-2010), were retrieved from the archives and the peripheral blood smear, bone marrow aspiration smears and trephine biopsies were examined for the common, uncommon and atypical features as described in the literature. Results: Out of the total of 16 cases, 10 were pediatric and 6 adult cases. The common findings like pancytopenia, peripheral blood monocytosis, increased histiocytes on aspirate smears and granulomas on biopsies were noted in 12/16 (75%), 9/16 (56.25%), 13/16 (81.2%) and 11/16 (69%) cases respectively. Amongst the uncommon findings, hemophagocytosis was noted in 12/ 16 (75%) cases, plasma cells with inclusions in 6/16 (37.5%) and LD bodies in cells other than histiocytes in 4/16 (25%) cases. The atypical findings included organism aggregates noted in 9/16 (56%) cases, Pelger-Heut cells seen in 4/16 (25%) cases and increased focal vascularity on biopsies in 10/16 (62.5%) cases. The average parasite density (APD) on smears was 3+ and the range of positivity was 1+ to 5+. Conclusion: The knowledge of these morphological clues can assist us in searching for LD bodies and correctly diagnosing the condition without excessive dependence on unnecessary and sophisticated tests

Amoebic liver abscess in the medical emergency of a North Indian hospital

<p>Abstract</p> <p>Background</p> <p>Amoebic Liver abscess although fairly common in developing countries, yet, there is limited data on the clinical presentation to the emergency department. A retrospective analysis of 86 indoor cases of Amoebic Liver Abscess presenting to the emergency department over a 5-year period was carried out.</p> <p>Findings</p> <p>The mean age of patients was 40.5 ± 2.1 years (male-female ratio = 7:1). Fever, pain abdomen and diarrhea were seen in 94%, 90% and 10.5% respectively. Duration of symptoms less than 2 weeks was seen in 48% cases. Hepatomegaly was present in 16% cases only, a right sided pleural effusion in 14% cases and ascites in 5.7%. On ultrasound, a right lobe abscess was seen in 65%, a left lobe abscess in 13% and multiple abscesses in both the lobes in 22% cases. Seventy one cases underwent per-cutaneous pigtail catheter drainage for a mean period of 13.4 ± 0.8 days. The mortality rate was 5.8%. On multivariate regression and correlation analysis, a higher number of inserted pigtail catheters correlated to mortality.</p> <p>Conclusions</p> <p>Amoebic liver abscess presents commonly to the emergency department and should be suspected in persons with prolonged fever and pain abdomen. Conservative management for uncomplicated amoebic liver abscess and insertion of single per-cutaneous pigtail catheter drainage for complicated amoebic liver abscess are efficacious as treatment modalities.</p

Methotrexate Induced Lung Injury in a Patient with Primary CNS Lymphoma: a Case Report

Methotrexate is an antimetabolite commonly used in clinical practice for a variety of indications ranging from rheumatoid arthritis and other connective tissue disorders to high dose regimens in many malignancies. This folate antagonist has got a spectrum of toxicities among which gastrointestinal effects predominate. Lung injury is a well described but rare event and has been reported most often in patients who have been on long term oral therapy for rheumatic disorders. Acute lung injury in a patient receiving a high dose regimen for haematological malignancies has not been reported previously. We present one such case of methotrexate related acute lung injury in a patient of primary CNS lymphoma receiving high dose methotrexate

A Study on the Expression of BCR-ABL Transcript in Mixed Phenotype Acute Leukemia (MPAL) Cases Using the Reverse Transcriptase Polymerase Reaction Assay (RT-PCR) and its Correlation with Hematological Remission Status Post Initial Induction Therapy

&lt;p&gt;&lt;strong&gt;Introduction&lt;/strong&gt;: The MPAL comprise 2-5% of all acute leukemia. The present WHO 2008 classification has separated two groups in MPAL based on t(9;22) positivity and MLL rearrangement. &lt;strong&gt;Aims &amp;amp; Objectives&lt;/strong&gt;: The aim of the present pilot study is to note the incidence of BCR-ABL transcript in MPAL cases using the RT-PCR assay and to correlate the status with hematological remission post induction. &lt;strong&gt;Materials &amp;amp; Methods&lt;/strong&gt;: A total of 10 MPAL cases classified on Flow-cytometry based on the current WHO 2008 criteria were enrolled. In all the cases Bone marrow or peripheral blood sample in EDTA was processed for molecular studies and the RT-PCR reaction carried out using primers specific to the t (9;22) and t(4;11) translocation. The post induction check marrow slides were also reviewed. &lt;strong&gt;Results&lt;/strong&gt;: Out of the total 10 MPAL cases, 7/10 (70%) were adult and 3/10 (30%) pediatric cases. A total of 4/10 (40%) cases showed positivity for the t(9;22) transcript and none for t (4;11). Of the 4 positive cases, 3/10(30%) were adult cases and 1/10(10%) pediatric case. The BCR-ABL transcript type in adult cases was b3a2 (p210) in 2/3 (66%) and e1a2 (p190) in 1/3 (33.3%) case. The single pediatric case was positive for b3a2 transcript. &lt;strong&gt;Discussion &amp;amp; Conclusion&lt;/strong&gt;: All the 4 positive MPAL cases presented with high TLC and low platelet count (p&amp;lt;0.05). The positive cases also showed hematological remission at post induction check marrow (blasts&amp;lt;5%). This could partly be explained due to good response to the imatinib added to the treatment protocol.&lt;/p&gt

Comparative evaluation of efficacy and safety of methotrexate either alone or in combination with hydroxychloroquine in patients suffering from rheumatoid arthritis

Background: Rheumatoid arthritis (RA) a chronic autoimmune inflammatory disease and Methotrexate being widely used as monotherapy and in combination for the treatment of RA. Combination therapy provides additional or even more potentiating effects, therefore have been widely used. This study is aimed at comparing the efficacy and safety of Methotrexate either alone or in combination.Methods: This study was conducted for one year from 1st January to 31st December 2015. 52 patients diagnosed with RA were included in this study and were divided in two groups, Group-1 (n=29) patients received methotrexate (MTX) 7.5-15mg/week and Group-2 (n=23) patients received methotrexate 7.5mg once a week + Hydroxychloroquine (HCQ) 200mg twice daily. The patients were followed up for a period of 16 weeks. Statistical analysis was done by using graph pad insta and p value of 0.05) in both the groups. Total of Adverse drug reactions reported were 42 (50.60%) in group-1 and 41 (49.40%) in group-2.Conclusions: The combination therapy was found to be more efficacious than MTX monotherapy in improving symptoms and quality of life. The adverse drug reactions were mild, more in combination therapy and none of the patients required withdrawal of treatment

MRI to assess chemoprevention in transgenic adenocarcinoma of mouse prostate (TRAMP)

<p>Abstract</p> <p>Background</p> <p>The current method to determine the efficacy of chemoprevention in TRAMP mouse model of carcinoma of prostate (CaP) is by extracting and weighing the prostate at different time points or by immunohistochemistry analysis. Non-invasive determination of volumes of prostate glands and seminal vesicles before, during and after treatment would be valuable in investigating the efficacy of newer chemopreventive agents in CaP. The purpose of this study was to determine whether <it>in vivo </it>magnetic resonance imaging (MRI) using a 3 tesla clinical MRI system can be used to follow the effect of chemoprevention in TRAMP model of mouse CaP.</p> <p>Methods</p> <p>Mice were randomized into control and treated groups. The animals in treated group received 10 µmol/kg of CDDO, 5 days a week for 20 weeks. Animals underwent <it>in vivo </it>MRI of prostate gland and seminal vesicles by a clinical 3 Tesla MRI system just before (at 5 weeks), during and at the end of treatment, at 25 weeks. T1-weighted and fat saturation (FATSAT) multiecho fast spin echo T2- weighted images (T2WI) were acquired. Volume of the prostate glands and seminal vesicles was determined from MR images. T2 signal intensity changes in the seminal vesicles were determined by subtracting higher echo time (TE) from lower TE T2WI. Following treatments all animals were sacrificed, prostate and seminal vesicles collected, and the tissues prepared for histological staining. All data were expressed as mean ± 1 standard deviation. Two-way or multivariate analysis of variance followed by post-hoc test was applied to determine the significant differences. A p-value of <0.05 was considered significant.</p> <p>Results</p> <p>Histological analysis indicated tumor in 100% of control mice, whereas 10% of the treated mice showed tumor in prostate gland. Both MRI and measured prostate weights showed higher volume/weight in control mouse group. MRI showed significantly higher volume of seminal vesicles in control animals and T2 signal intensity changes in seminal vesicles of control mice indicating higher number of tumor foci, which was also proven by histology.</p> <p>Conclusions</p> <p><it>In vivo </it>MRI is helpful in determining the efficacy of chemoprevention of prostate cancer in TRAMP mice.</p

A note on comonotonicity and positivity of the control components of decoupled quadratic FBSDE

In this small note we are concerned with the solution of Forward-Backward Stochastic Differential Equations (FBSDE) with drivers that grow quadratically in the control component (quadratic growth FBSDE or qgFBSDE). The main theorem is a comparison result that allows comparing componentwise the signs of the control processes of two different qgFBSDE. As a byproduct one obtains conditions that allow establishing the positivity of the control process.Comment: accepted for publicatio
