ABSTRACT
Background: A bone marrow evaluation encompasses bone marrow aspirate (BMA) and bone marrow biopsy (BMB) along with a review of peripheral smear examination. However, due to variations in practice, bone marrow core biopsy is not performed for all patients. Aim: To compare the diagnostic utility of simultaneous BMA and BMB and to study the concordance rate between the two. Material and methods: All BMA and BMB that were simultaneously done between January 2008 and December 2010 in a multispecialty hospitals were reviewed and analyzed in detail. Results: Four hundred sixty-six aspiration and biopsy slides were reviewed. The commonest indication was anemia (40.3%) followed by pyrexia of unknown origin (36.2%); 15.2% aspirates and 6.4% biopsies were inadequate. The overall concordance rate between aspirates and biopsy was found to be 62.8%. Concordance was highest for acute and chronic leukemias, metastatic deposits, multiple myeloma and tuberculosis and least for lymphoproliferative disorders, myelofibrosis and marrow hypoplasia. Trephine biopsy was useful for patients’ with multiple myeloma, acute leukemias, lymphoproliferative disorders, myelofibrosis, marrow hypoplasia, osteitis fibrosa cystica and metastasis. BMB and BMA could detect tuberculous granulomas in 85.17% and 57.14% cases, respectively. However, parasitic infections (kala-azar, malaria) could be diagnosed exclusively in BMA. Conclusions: BMA and BMB are important, useful complementary diagnostic tools giving a higher diagnostic yield when used in conjunction.
ABSTRACT
Background: The educational environment in a college is one of the most important factors in determining the success of the curriculum and the student. The DREEM inventory is a validated global instrument for measuring the educational environment in undergraduate medical education. A study was undertaken to assess the educational environment as perceived by the students of a new medical college established in India in 2008. Objectives: To compare the quality of the educational environment in preclinical years as perceived by the first two batches of students in a new medical college so that appropriate remedial measures could be taken, and also to identify gender differences, if any in the students’ perception. Methods: The DREEM questionnaire was administered to 156 students (2008 batch, n=56 and 2009 batch, n=100) on different occasions after a lecture class. Purpose of the study was explained to the students before administering the questionnaire. Confidentiality was maintained. Statistical analysis used: Cronbachs alpha for internal consistency and reliability. Unpaired t test was used for comparison. Results: The response rate was 100% (256 /256 students). The overall DREEM score was 126.3/200 indicating that perception of the educational environment of the medical school was more positive than negative. However, the study revealed some problem areas within the educational environment. Conclusion: A large number of diverse and hidden factors influence the way students perceive their educational environment. It should be a continuous process to monitor the feedbacks from the students to identify problem areas so that necessary remedial measures can be instituted at the earliest.
ABSTRACT
Background: Celiac disease is an autoimmune disorder caused by the ingestion of wheat gluten and related proteins in genetically susceptible individuals. It is characterized by anti-tissue transglutaminase (anti-tTG) antibodies. Duodenal biopsy is the gold standard for diagnosis. Correlation of clinical, serologic, and histological features is essential for a definitive diagnosis. The ratio of diagnosed versus undiagnosed cases is quite high. Aims: This study aimed to correlate the degree of mucosal damage with anti-tTG levels, mean baseline hemoglobin and endoscopic findings. Setting and Design: Two hundred twenty six adults suspected to have celiac disease were studied. Marsh grades were compared with anti-tTG levels, hemoglobin, endoscopy, and clinical presentations. Materials and Methods: Esophagogastroduodenoscopy, serum levels of anti-tTG, complete hematologic work-up, and duodenal biopsy were performed in all 226 cases (including three siblings of confirmed patients) with well-defined symptom groups. Histopathological grading was done as per modified Marsh system. Correlation of all the parameters was performed with Marsh grades. Statistical Analysis : Performed on SPSS version 15.0. Tests applied include one way ANOVA, Chi-square test, repeated measure analysis, and Bonferroni's method for comparison. Results were considered significant when P<0.05. Results and Conclusions: Anti-tTG levels, mean baseline hemoglobin, and endoscopic findings were found to correlate with increasing severity of mucosal damage with P<0.001 for all. Anti-tTG levels of grades 1+2 and those of grade 3a were significantly different from levels of grades 3b and 3c+4 with P<0.001 for each. Varied clinical presentations of celiac disease were seen in the adult wheat eaters of North India.
