    Aetiological studies on hospital inpatients with secretory diarrhoea in Calcutta.
    (1992-01-01) Basak, S; Chakraborty, P S; Chandy, J; Bhattacharya, M K; Rasaily, R; Ramamurthy, T; Sen, M
    Twenty-five cases of all age groups with secretory diarrhoea admitted to the Infectious Diseases Hospital, Calcutta were studied. Bacterial enteropathogens were detected by bacteriological examination of the faeces, in each and every case. The main pathogens detected were Escherichia coli and Vibrio cholerae. V cholerae was more commonly associated with severe illness except in the very young, while Esch coli was equally associated with moderate and severe illness. Multiple isolates were more commonly associated with severe illness and single isolates were more common in illness of moderate severity.

    Association of dietary fiber with high sensitivity C-reactive proteinin type 2 diabetes mellitus.
    (2012-04) Begum, I A; Sen, M; Afrin, S F; Moutoshi, S S; Islam, M A; Rahman, M H
    Introduction: Hs-CRP is a nonspecific marker of the inflammatory response has been associated with development of type 2 diabetes mellitus. Cardiovascular disease is a major consequence of diabetes. DM confers a 2-4 fold rise in cardiovascular risk compared with general population. One of the many modifiable risk factors for both cardiovascular disease and diabetes is diet. Fiber is an important dietary factor that may modify the risk of both diseases. Material & methods: The current study is an attempt to explore the association of dietary fiber on inflammatory marker, hs-CRP in type2 diabetic subjects. Total 80 diabetic subjects were included in this study of which 40 were taking more dietary fiber and 40 were taking relatively low dietary fiber. Serum hs-CRP was measured by chemiluminescent immunometric assay (DPC Biermann Gmbh., Germany). Nutrient information was calculated using a pretested food recall questionnaire prepared by nutritionists for usual Bangladeshi food articles. Results: Hs-CRP was significantly higher in subjects taking low dietary fiber. There was significant negative correlation between CRP of subjects taking high and low intake of dietary fiber. Conclusion: So, low dietary fiber consumption maybe a possible causal factor of raised CRP. Type 2 diabetic patients who took less dietary fiber in their diets had elevated blood CRP levels.

    Circumscribed choroidal hemangioma: An overview of clinical manifestation, diagnosis and management
    (All India Ophthalmological Society, 2019-12) Sen, M; Honavar, SG
    Circumscribed choroidal hemangioma is a benign vascular tumor which presents in middle-aged adults with progressive diminution of vision, metamorphopsia, floaters, and visual field defects. Diagnosis is based on the characteristic clinical features. It is an orange-red, usually solitary, tumor situated in the posterior pole. The visual symptoms are because of the associated subretinal fluid, cystoid macular edema, and, in long-standing cases, retinal pigment epithelium changes, subretinal fibrosis and retinoschisis. It must be distinguished from the more ominous amelanotic melanoma and choroidal metastasis. Diagnostic tools such as ultrasound, fundus fluorescein angiography, indocyanine green angiography, and optical coherence tomography are helpful in cases with diagnostic dilemma. Treatment is indicated in symptomatic cases. The management of choroidal hemangioma has evolved over the years beginning with laser photocoagulation to transpupillary thermotherapy, photodynamic therapy, plaque brachytherapy and external beam radiotherapy. No one therapeutic option holds superiority over the other. In this article, we review the epidemiology, clinical manifestations and treatment of the circumscribed variant of choroidal hemangioma.

    Coats disease: An overview of classification, management and outcomes
    (All India Ophthalmological Society, 2019-06) Sen, M; Shields, CL; Honavar, SG; Shields, JA
    Coats disease is an idiopathic retinal vascular disorder with retinal telangiectasia with intraretinal and/or subretinal exudation without appreciable retinal or vitreal traction. The condition is sporadic with no associated systemic abnormalities. Unilateral involvement in young males is the typical presentation with most cases being diagnosed in the first and second decade of life. Younger the patient, more severe is the presentation and poorer the visual outcome. The management varies with the stage of the disease. Over the years, we have shifted from enucleation to a more conservative approach for the treatment of Coats disease with laser photocoagulation, cryotherapy and surgery for retinal detachment achieving good outcomes. The anti-VEGF agents have come into the scene as important form of adjuvant treatment along with the traditional management options. This article describes the clinical features, underlying pathology, classification and staging, the complications and the management of Coats disease and gives an overview of the changing trends in treatment and outcomes spanning across five decades.

    Intrathecal buprenorphine for postoperative analgesia in orthopaedic surgery.
    (1992-01-01) Sen, M
    Sixty patients aged 50-65 years randomly received intrathecally either hyperbaric bupivacaine hydrochloride (one ml) in group A (30 cases) or bupivacaine hydrochloride (one ml) and buprenorphine 300 micrograms in combination in group B (30 cases). They were all scheduled for orthopaedic operations in the lower limbs. Prolonged postoperative analgesia, minimal disturbance of consciousness and respiration were observed in the group that received buprenorphine. The only side-effect found in the buprenorphine group was nausea and vomiting in 10 patients. This study shows that buprenorphine is an effective analgesic suitable for the management of postoperative pain in elderly patients.

    Molecular characterization of the ligninolytic Sundarban mangrove isolate Stenotrophomonas maltophilia GD1 and its promising applications in the dye and fiber industry
    (Open Science Publishers LLP, 2024-12) Das, S; Sen, M; Sinha, N; Kumar, S; Dasgupta, N; Ghosh, D.
    Lignocellulolytic biocatalysts, including laccase, cellulase, and pectinase, have high potential for degrading lignocellulosic biomass (LCB). Jute and banana are fiber-producing LCBs that hold significant economic value. Nevertheless, certain parts of these plants are utilized as waste material due to their low-quality fiber, which causes losses for the industry. These waste portions can be processed and biologically converted into high-value fiber. A bacterial strain called Stenotrophomonas maltophilia GD1, which can produce several proteins, was isolated from the Sundarban mangrove ecosystem in West Bengal, India, and genetically analyzed via 16S rRNA sequencing. The strain exhibited the ability to produce all three necessary lignocellulolytic enzymes, with the highest levels of laccase and minimal cellulase and pectinase activity. The strain modified the fibers extensively, as determined by Young’s modulus, and removed the color from the toxic industrial dyes. This demonstrates the broad potential of this strain for waste valorization and environmental remediation. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) confirmed the enhanced fiber quality. Microbial phylogenetic relationships were established using Molecular Evolutionary Genetics Analysis version 11 (MEGA 11).
