Health Risk Perceptions, Awareness and Handling Behaviour of Pesticides by Farm Workers

The level of awareness regarding pesticide use/ handling has been reported in the farms of Kerala and the same has been compared with the adoption pattern and experiences of health risk episodes, in a society with high level of literacy. The understanding on various aspects of pesticide-use has revealed better awareness in certain aspects and poor understanding in certain others. The workers have not been given adequate training to understand the toxicity level by looking at the colour code on the packet, though they have been found aware about the different options available in the market. Often their perceptions of toxicity level of chemicals they handle are not in conformity with the actual situation; they have been found handling toxic chemicals considering them to be safe ones. Despite a high literacy level, most of them do not care to read the instructions and follow them. The study has found that a majority of the respondents are of satisfactory health status by the body mass index values. The short-term health risk upon occupational exposure has been reported very common; its frequency increases as one gets more years of experience in the work. It has been attributed to their inadequate understanding of the toxicity levels, unscientific handling practices and poor personal protective mechanism. The study has highlighted the need for targeted trainings to farm labourers besides farmers on the scientific management of pesticides and undertaking of massive awareness generation programmes.Agricultural and Food Policy,

Is Irrigation Water only Used for Irrigation? An Enquiry into the Alternative Uses and an Attempt on Valuation

Irrigation sector investments in Kerala have been mounting since Independence, but the financial performance of these investments has been far from satisfactory. In an era of growing divergence in water supply and demand, the emergence of water markets is imminent. This calls for a realistic pricing strategy for water use, whether in agriculture or other sectors. The canal water though targeted at the agriculture sector, is often put to non-irrigation uses. This paper has discussed a method to quantify the non-irrigation uses of canal water and has assessed the value of the same, based on a sample study in Peechi Irrigation Command Area in Thrissur district of Kerala, India . The value has been assessed for the water used directly for irrigation from the canal system, water used through the recharge facility from the canal and non-irrigation uses (domestic).Agricultural and Food Policy,

Pesticide Use in the Rice Bowl of Kerala: Health Costs and Policy Options

This study examines pesticide use in Kuttanad, India, an economically sensitive area often referred to as the rice bowl of Kerala. Using primary data collected from pesticide applicators and farm labor, the study assesses short-term health costs associated with pesticide exposure. The study finds that the toxicity level and dose of pesticides can exert a significant effect on the health of pesticide applicators. The average expected health costs from pesticide exposure are Rs. 38 (US $ 0.86) per day or 24% approximately a quarter of the average daily earnings of the applicator. // The study finds that health costs can be mitigated considerably by reducing the dose of pesticides used. For examples, a 25% reduction in either the does of the most toxic chemical used, or in all pesticide doses, results in a 16% and 24% reduction in health costs respectively. A 24% reduction in costs can be realized if all pesticide doses are reduced by 25%. Dose reduction is a desirable and feasible strategy that can be achieved either by restricting the quantity of pesticide used or by diluting the amount sprayed with the recommended levels of water. Less than 2% of the applicators understood the toxicity levels of the pesticides they used. Thus, there is ample scope for reducing pesticide exposure through training and agricultural extension services

An unusual bilateral variation of musculocutaneous nerve.

Musculocutaneous nerve arises from the lateral cord (C5,6,7) of brachial plexus. Communications between the branches of brachial plexus are not so common. During routine dissection, we observed bilateral variation in 60-year-old female cadaver. In the present case, median nerve represented as a musculocutaneous nerve which supplied biceps brachii and brachialis, further continued into forearm as lateral cutaneous nerve of forearm on the right arm. This branch did not pass through coracobrachialis muscle but the coracobrachialis was innervated by a branch from lateral cord of brachial plexus. We also observed an abnormal communicating branch between the musculocutaneous and median nerve on left side of the arm. These kinds of variations are important for surgeons while performing surgeries of axilla and upperlimb

Facing hazards at work : agricultural workers and pesticide exposure in Kuttanad, Kerala

This policy brief is based on SANDEE working paper no. 20-07, "Pesticide use in the rice bowl of Kerala : health costs and policy options"Pesticides are responsible for hundreds of cases of poisoning in the developing world, where information and training on the potential negative health effects of these chemicals is often lacking. While the impact of the indiscriminate use of toxic chemicals is widely acknowledged, the economic costs of this misuse are less well known. This has held back investment in the necessary health and safety programmes that can safeguard people’s well-being

Organic Farming in India : Catalysts that Can Help in Transition

Organic farming has been receiving policy support from both the central and state governments in India since 2005. The shift in policy thrust from conventional chemical-input based farming to organic farming comes as a response to the sustainability concerns surrounding Indian agriculture. Despite this,organicfarming remains niche, with less than 2% of the net sown area in the country under organic production. This paper suggests market-based instruments—which have been successful in inducing changes in farming practices in some countries across the globe—as complementary policy mechanisms for catalysing the transition to organic farming in India

Role of Decompressive Craniectomy in the Management of Cerebral Venous Sinus Thrombosis

Cerebral venous sinus thrombosis (CVST) is a relatively uncommon cause of stroke more often affecting women and younger individuals. Blockage of the venous outflow rapidly causes edema and space-occupying venous infarctions and it seems intuitive that decompressive craniectomy (DC) can effectively reduce intracranial pressure just like it works for malignant middle cerebral artery infarcts and traumatic brain injury. But because of the relative rarity of this type of stroke, strong evidence from randomized controlled trials that DC is a life-saving procedure is not available unlike in the latter two conditions. There is a possibility that other forms of interventions like endovascular recanalization, thrombectomy, thrombolysis, and anticoagulation, which cannot be used in established middle cerebral artery infarcts and TBI, can reverse the ongoing pathology of increasing edema in CVST. Such interventions, although presently unproven, could theoretically obviate the need for DC when used in early stages. However, in the absence of such evidence, we recommend that DC be considered early as a life-saving measure whenever there are large hemorrhagic infarcts, expanding edema, radiological, and clinical features of impending herniation. This review gives an overview of the etiology and risk factors of CVST in different patient populations and examines the effectiveness of DC and other forms of interventions

Complications of Decompressive Craniectomy

Decompressive craniectomy (DC) has become the definitive surgical procedure to manage medically intractable rise in intracranial pressure due to stroke and traumatic brain injury. With incoming evidence from recent multi-centric randomized controlled trials to support its use, we could expect a significant rise in the number of patients who undergo this procedure. Although one would argue that the procedure reduces mortality only at the expense of increasing the proportion of the severely disabled, what is not contested is that patients face the risk of a large number of complications after the operation and that can further compromise the quality of life. Decompressive craniectomy (DC), which is designed to overcome the space constraints of the Monro Kellie doctrine, perturbs the cerebral blood, and CSF flow dynamics. Resultant complications occur days to months after the surgical procedure in a time pattern that can be anticipated with advantage in managing them. New or expanding hematomas that occur within the first few days can be life-threatening and we recommend CT scans at 24 and 48 h postoperatively to detect them. Surgeons should also be mindful of the myriad manifestations of peculiar complications like the syndrome of the trephined and neurological deterioration due to paradoxical herniation which may occur many months after the decompression. A sufficiently large frontotemporoparietal craniectomy, 15 cm in diameter, increases the effectiveness of the procedure and reduces chances of external cerebral herniation. An early cranioplasty, as soon as the brain is lax, appears to be a reasonable choice to mitigate many of the late complications. Complications, their causes, consequences, and measures to manage them are described in this chapter
