Environmental Consequences of Intensive Aquaculture Practices at Moyna Purba Medinipur West Bengal India with Special Reference to Carbon Footprint and Carbon Sequestration.

Moyna of Purba Medinipur district is widely known as an aquaculture hub of West Bengal, India. Though very good production is achievable from this fish culture system, management practices are inappropriate, which could create the sustainability problem of this culture system. The present study was thus undertaken for the estimation of plankton population, water quality, carbon footprint and carbon sequestration of this intensive aquaculture practices. Information on spawn to fry, fry to fingerlings and grow-out culture were collected through the structured questionnaire from the fish farmers. The plankton density, primary productivity, carbon footprint and carbon sequestration were analyzed using standard procedures. The phytoplankton, zooplankton and primary productivity were maximum at the stocking period and minimum during the middle of culture period. The lowest feed conversion ratio (FCR) was noticed with the minimum amount of feed applied in the pond. The CO2-e emission ranged from 0.56 to 4.89 kg CO2-e/kg fish (av. 2.13) for the production levels of 5.0 to 10.7 t/ha/yr. The pond water developed salinity and ammonium-N increased from 0.01 to 0.50 mg/l. The ponds with high feed loading (28 to 32 t/ha/yr) had the highest average sediment accumulation rate (11.0 ± 3.0 cm/yr) and carbon sequestration (704 ± 30 g C/m2/yr).

Patient's Knowledge and Attitude towards Tuberculosis in an Urban Setting.

Tuberculosis is a public health problem in Bangladesh. This cross-sectional study was conducted to assess knowledge of TB patients about symptoms, ways of transmission and treatment of tuberculosis, and their perception of the illness. Between March and August 2008, 762 adult TB patients were interviewed at selected DOTS centre of Dhaka city. Male and female distribution was 55.6% and 44.4%, respectively. One quarter of them were illiterate, and more than half had extended family and live in a congested situation. Night fever was the most common symptom known (89.9%), and 56% were aware that it could spread through sneezing/coughing. Television was mentioned as a source of information about TB. The majority expressed a helping attitude towards other TB patients. Although most of them were positive about getting family support, 46.6% mentioned discrimination of separate utensils for food or drink. About 50.5% expressed increased sadness, 39.8% had fear of loss of job/wedges, and 21.4% felt socially neglected. Along with drug treatment the psychosocial reactions of TB patients should be addressed at DOTS centers for better control of the disease.

Back pain in a Bangladeshi worker in Iraq.

Pyogenic Spinal Infection (PSI) is an uncommon disorder encompassing a broad spectrum of diseases including septic spondylodiscitis, osteomyelitis, epidural and paravertebral abscess formation. Presentation can be vague and highly variable but usually includes back pain and fever. Whilst predisposing factors, such as trauma and diabetes can often be identified a pathogenic organism may not be identified in up to a half of all cases leading to significant delay in both accurate diagnosis and effective treatment. Precise spinal imaging is essential and includes plain X-ray, CT and preferably MRI. The treatment of PSI can be conservative (including antibiotics); however, spinal surgery may be required for the complications in up to 50% of cases, with varying degrees of success. We present a challenging case of PSI encountered in a locally-employed 42-year-old Bangladeshi civilian working in Iraq. Despite obvious resource limitations available within a Role 2 Field Hospital, clinical suspicion coupled with repeat spinal CT was pivotal in obtaining the diagnosis. The patient was repatriated to Bangladesh for MRI and definitive surgical treatment.

Store-and-forward teleneurology in developing countries.

We assessed the feasibility of a store-and-forward email teleneurology service between a UK neurologist and a rehabilitation hospital in Bangladesh. Over 12 months, email advice was requested for 12 patients (mean age 43 years, range 15-57 years). Each patient generated an average of 5.2 email messages. Eight cases were considered complicated by the neurologist, who would have preferred a video-link consultation for these. The referring doctor found the neurologist's advice beneficial in 75% of the complex cases and in all of the more straightforward cases. Patient care was changed in 50% of the cases as a result of the specialist advice and one patient transfer out of the country was avoided. Store-and-forward teleneurology is effective for delivering expert neurological advice.

An evaluation of the first year's experience with a low-cost telemedicine link in Bangladesh.

In July 1999, the Swinfen Charitable Trust in the UK established a telemedicine link in Bangladesh, between the Centre for the Rehabilitation of the Paralysed (CRP) in Dhaka and medical consultants abroad. This low-cost telemedicine system used a digital camera to capture still images, which were then transmitted by email. During the first 12 months, 27 telemedicine referrals were made. The following specialties were consulted: neurology (44%), orthopaedics (40%), rheumatology (8%), nephrology (4%) and paediatrics (4%). Initial email replies were received at the CRP within a day of referral in 70% of cases and within thee days in 100%, which shows that store-and-forward telemedicine can be both fast and reliable. Telemedicine consultation was complete within three days in 14 cases (52%) and within three weeks in 24 cases (89%). Referral was judged to be beneficial in 24 cases (89%), the benefits including establishment of the diagnosis, the provision of reassurance to the patient and referring doctor, and a change of management. Four patients (15% of the total) and their families were spared the considerable expense and unnecessary stress of travelling abroad for a second opinion, and the savings from this alone outweighed the set-up and running costs in Bangladesh. The latter are limited to an email account with an Internet service provider and the local-rate telephone call charges from the CRP. This successful telemedicine system is a model for further telemedicine projects in the developing world.
