Melioidosis is endemic in the South Asian regions, like Thailand, Singapore Malaysia and Australia. The disease is more pronounced in the southern part of the country. It is caused by Burkholderia pseudomallei which causes systemic involvement, morbidity and mortality associated with the disease is high. Due to highly varied clinical presentation, and low general awareness this infection is largely underdiagnosed and under reported in our country. Most laboratories in the country still rely on conventional culturing methods with their low sensitivity, adding to the under reporting. To enhance physician awareness we describe here two cases who presented to our institute after months of misdiagnosis. Source

Screening coagulation tests and assays for thrombosis and fibrinolysis were performed in 80 cases of malaria at presentation and during the course of the disease. Close correlation between the degree of thrombocytopenia (observed in >97% cases) and the presence hemorrhagic manifestations at presentation, and improvement in the platelet count in parallel with clinical recovery emphasised the role of platelets in the pathogenesis of coagulopathy in malaria. A potential selection bias resulting from inclusion of only patients admitted at a tertiary care hospital could explain the higher incidence (27.5%) of clinical bleeding observed in this study compared to that reported in the literature. Although a significant correlation between overt bleeding and abnormal PT/INR and APTT (observed in 20-37% cases) could not be demonstrated, a good correlation existed between normal screening coagulation tests and the absence of bleeding complications. Elevated D-Dimer and FDP levels in almost all cases (90%) of both types of malaria confirmed the high prevalence of disseminated intravascular coagulation and fibrinolysis. A correlation between rising D-Dimer levels and the incidence of bleeding was observed. Follow up studies in six cases with complications showed normalization of platelet counts and of screening coagulation assays with clinical recovery. D-Dimer and FDP levels however, remained elevated in most of these cases indicating the continuation of a smouldering coagulopathy even after full clinical recovery possibly due to the persistence of residual damage to the cells caused by the parasitic infection. Knowledge of this fact is important for avoiding unnecessary investigations and longer hospital stay in patients admitted with malaria. © 2011 Indian Society of Haematology & Transfusion Medicine.

Phenotypic variability and the lack of a diagnostic marker have complicated the rapid diagnosis and genetic counseling for Cornelia de Lange syndrome (CdLS). The clinical features of CdLS are striking and easily recognizable by characteristic facial dysmorphism, upper-extremity malformations, hirsutism, cardiac defects, growth and cognitive retardation, and gastrointestinal abnormalities with severe mental retardation. The molecular diagnosis is essential for predicting prognosis and genetic counseling in the affected family, especially while planning the next pregnancy. We report here from India six cases of CdLS and how precise mutational screening in two cases helped in prenatal diagnosis and proved significant in prevention of recurrence in the affected family. © Federation of Obstetric & Gynecological Societies of India 2013.

Objective : To study the antimicrobial (AM) consumption, record the AM sensitivity pattern, and evaluate impact of "Reserve AM indent form" in the intensive care unit (ICU). Materials and Methods : The study was carried out in medical ICU over 4 months period at a tertiary care hospital. AM consumption was determined by defined daily dose (DDD) per 100 bed days for each month for consecutive 4 months. The average total AM consumption was calculated. The laboratory samples were processed, and the sensitivity pattern was determined. Some of the newer AM were categorised as "Reserve" and an indent form was made mandatory to be filled up prior to prescription. Results : The total AM consumption was 232 per 100 bed days. The commonly used AM were penicillin with β-lactamase inhibitor (21%) followed by antifungal drugs (13.4%), cephalosporins and macrolides (11.7%) each. The most common organism isolated was Acinetobacter (26.1%) followed by Candida (23.8%) and Pseudomonas (21.4%). The average occupancy index was 0.53, and the average duration of ICU stay was 6 days. The consumption of carbapenems (new AM) and antifungals decreased from 18.8/100 to 10.6/100 and 56.1/100 to 22.1/100 bed days, respectively, after the introduction of indent form. Conclusion : The "Reserve AM indent form" was helpful in reducing the AM consumption during the study period. The AM indent form can be used as an important tool to combat irrational use, AM resistance and can be implemented in AM stewardship programmes. Source

Context: Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal stem cell disorder characterized by complement-mediated hemolysis due to reduced expression of glycosyl phosphatidylinositol-anchored complement deactivating proteins such as CD55 and CD59 on RBC. Flow cytometric analysis of CD55 and CD59 expression by RBC is a reliable tool for the diagnosis of PNH. Aims: Detection and quantification of PNH clone and comparison of the relative role of CD55 and CD59 expression by RBC in the diagnosis of PNH. Materials and Methods: Flow cytometric analysis of RBC was performed in blood samples of 239 patients by direct immunofluorescence using monoclonal anti-CD55 and anti-CD59 antibodies. CD55 and CD59 expressions by RBC were compared in 54 cases in which PNH clones were detected. Results: Out of 54 cases, 85% and 72% revealed CD59 and CD55 negative populations, respectively. Various combinations of type II and III erythrocytes could be identified in all cases having CD59 deficient RBC. In contrast, distinct populations of CD55-deficient RBC were seen in only 33% cases. In the remaining (67%) cases, CD55 negative RBC caused sloping of the ascending limb of the histogram resulting in difficulties in interpretation. Fifteen percent cases had false CD55-deficient RBC and in 23% cases anti-CD55 antibody failed to identify PNH clones which were detected by CD59. Conclusion: CD59 is a better marker for the diagnosis of PNH. Although CD55 negativity supported the diagnosis of PNH in cases with CD59-deficient RBC, its role as an independent diagnostic marker for PNH is questionable due to its lower sensitivity and specificity.
