Neutrophil extracellular traps in patients with pulmonary tuberculosis

Abstract: Tuberculosis is a devastating infectious disease causing many deaths worldwide. Recent investigations have implicated neutrophil extracellular traps (NETs) in the host response to tuberculosis. The aim of the current study was to obtain evidence for NETs release in the circulation during human tuberculosis. For this we measured the plasma concentrations of nucleosomes in conjunction with neutrophil elastase, in 64 patients with active pulmonary tuberculosis and 32 healthy controls. Patients with active tuberculosis had elevated plasma levels of nucleosomes and elastase when compared with local healthy blood donors. Furthermore nucleosome and elastase levels showed a positive correlation. These findings provide the first evidence for the release of NETs in the circulation of patients with active pulmonary tuberculosis.

Diagnosis of breast lump by fine needle aspiration cytology and mammography.

Abstract: Breast carcinoma is the most common malignant tumour and the leading cause of death from cancer in women. A large number of patients in Bangladesh have been suffering from breast cancer. Now-a-days, Fine needle aspiration cytology (FNAC) is being performed as a pre-operative test to evaluate breast lump. FNAC is cost effective and can prevent unnecessary surgery. As FNAC became more reliable in diagnosing malignancy and thereby the use of frozen-section histology had been reduced by about 80%. But erroneous diagnosis is more common with FNAC than with histopathology. However, mammography can identify breast cancers too small to palpate on physical examination and theoretically beneficial to diagnose even noninvasive lesions. Present study aimed to see the accuracy of FNAC and mammography in the diagnosis of palpable breast lumps and to study their correlation. In this study 222 patients were included in the study and FNAC was done in all the patients. Mammography was done in 112 cases. Among these 112 patients 32 cases were found malignant. Histopathology was done in total 89 cases. Among 112 patients who were underwent mammography only 43 were found for histopathology. Finally, 36 cases were found malignant. Fibroadenoma is mostly found in below 20 years group and malignancy is mostly occurring in older age group. Mammography shows total 8 false positive and 5 false negative cases. FNAC shows only 1 false positive and 1 false negative case. On analysis mammography showed 82.76% sensitivity, 90.36% specificity, 75% Positive predictive value (PPV), 93.75% Negative predictive value (NPV) and 88.39% accuracy. FNAC showed 97.22% sensitivity, 99.46% specificity, 97.220% PPV, 99.46% NPV and 99.095% accuracy. Mammography was found to be less sensitive, specific and accurate in the diagnosis of breast lump though there is highly significant correlation among them. However, the study has shown a much higher performance of FNAC than other previous studies indicating the improved skill in cytological diagnosis to a satisfactory level.

Ongoing efforts to improve the management of patients with diabetes in Bangladesh and the implications.

Abstract: Prevalence rates of patients with diabetes are growing across countries, and Bangladesh is no exception. Associated costs are also increasing, driven by costs associated with the complications of d...

Pathogenesis of Drug Induced Non-Allergic Angioedema: A Review of Unusual Etiologies

Abstract: Angioedema is the swelling of mucosal and sub-mucosal tissue. Typically, it manifests as the swelling of the face, lips, and tongue. Angioedema can be severe and life threatening when it involves the respiratory tract. Drug induced allergic angioedema and drug induced non-allergic angioedema differ in their mediator, their clinical presentations, and their management. In drug induced non-allergic angioedema, symptoms are resistant to antihistamine and corticosteroid treatment. The aim of the analysis was to identify which medications are associated with drug-induced non-allergic angioedema and to understand the mechanism of action via which of these medication cause angioedema.

Leprosy reactions in postelimination stage: the Bangladesh experience

Abstract: Background Leprosy reactions are immunologically mediated conditions and a major cause of disability before, during and after multidrug therapy. Little data has been published on the epidemiology of leprosy reactions in Bangladesh. Objectives To describe the pattern and prevalence of leprosy reactions in the post elimination stage. Methods A descriptive retrospective cross-sectional study was carried out in Chittagong Medical College Hospital using the registered records of patients the periods between 2004 and 2013. Results Of the 670 leprosy patients 488 (73.38%) were males and 182 (27.37%) were females. The prevalence of reaction was 300 (44.78%) with a male: female ratio of 3.55:1. The age specific cumulative reactions cases at >40 years was high 115 (38.33%) among all age groups. The prevalence of reaction was found to be 166 (55.33%) for the reversal reaction, 49 (16.57%) for the erythema nodosum leprosum and 85 (28.33%) for the neuritis. Borderline tuberculoid was the most common 106 (35.33%) group in reversal reaction while lepromatous leprosy was the most common 37 (12.33%) in erythema nodosum leprosum. More than half of the patients 169 (56.33%) had reactions at the time of presentations while 85 (28.33%) and 46 (15.33%) of patients developed reaction during and after multidrug therapy respectively. The reversal reaction group presented with ≥ 6 skin lesions in 96 (57.83%) and ≥ 2 nerves involvement in 107 (64.46%) patients. The erythema nodosum leprosum presented chiefly as papulo-nodular 45 (91.84%) lesions followed by pustule-necrotic 4 (8.16%) lesions, neuritis 33 (67.35%), fever 24 (48.98%), lymphadenitis 6 (12.24%), arthritis 5 (10.20%) and iritis 2 (4.08%). Bacterial index ≥ 3 had been demonstrated in 34 (60.71%) patients of erythema nodosum leprosum. Conclusion The incidence of leprosy reaction seemed to be more than three times common in borederline tuberculoid (52.33%) than in lepromatous leprosy (14%). Reactions with nerve function impairment and disability still occur among multibacillary patients during and after multidrug therapy. Early detection and management of leprosy reaction is very important in preventing disability and deformity, and patients should be educated to undergo regular follow-up examinations. Developing reinforced new therapies to curb leprosy reactions is crucial for improving leprosy health care services. This article is protected by copyright. All rights reserved.
