Pesticides and Chronic Diseases

Signs and symptoms of OP toxicity and even sensitivity do not always correlate with biological measurements of poisoning (cholinesterase activity in the blood). In an episode reported by Xintaras et al.,190 workers in a Texas manufacturing plant who were exposed to leptophos, an OP pesticide, showed normal cholinesterase activity. Before the correct diagnosis was made, physicians suspected encephalitis and other diseases, since the signs and symptoms included impaired memory, disorientation, drowsiness, headache, tremulousness, dizziness, anxiety, hallucinations, etc. We have had similar experiences of normal cholinesterase in some sensitive patients exposed to OP pesticides at the EHC-Dallas. Xintaras et al.190 suggested that baseline data are imperative to accurately monitor the effects of these chemicals.190

Other viral diseases such as epidemic polyarthritis, Rift Valley fever, Ross River fever, St. Louis encephalitis (SLE), WNV, Japanese encephalitis (JE), La Crosse (LAC) encephalitis, and several other encephalitis-type diseases are carried by several different mosquitoes. Eastern equine encephalitis (EEE) and western equine encephalitis (WEE) occur in the United States where they cause disease in humans, horses, and some bird species. Because of the high mortality rate, EEE and WEE are regarded as two of the most serious mosquito-borne diseases in the United States. Symptoms range from mild flu-like illness to encephalitis, coma, and death.8

Acute encephalitis is inflammation of the brain caused by several organisms, the commonest being viruses such as herpes simplex type 1. This is the commonest cause of acute encephalitis in Europe and causes a severe infection with case fatality rates that may be as high as 70 per cent. Encephalitis can also occur as an acute complication of measles and varicella infections.

Whereas JE (Japanese encephalitis) is caused by mosquito vector Culex tritaeniorhynchus distributed mostly in south Asia and southeast Asia [5] and has reported a mortality of about 30,000–50,000 annually. These vectors breeds especially in irrigation waters of rice field and uses pigs as their amplification host. The symptoms of Japanese Encephalitis infections are mild, with or without apparent symptoms, but many reports suggest that certain patients results in severe disease characterized by raise in body temperature, headache, neck stiffness, disorientation, coma, seizures, spastic paralysis and death. Control of mosquito is something important in the present day with rise in number of illness caused by mosquito and it is a major sources for death in developing countries.

Brain tumours and inflammatory lesions are two common brain diseases and are of primary concern in medicine. However, to distinguish them, it is easy to get confused. The formation of brain tumours is caused by the growth of abnormal cells in the tissues of the brain (McFaline-Figueroa and Lee 2018). Brain tumours can be benign, without cancerous cells, or malignant with rapidly growing cancerous cells. Some tumours are primary, which starts right in the brain, and others are metastatic, where they start somewhere else in the body and spread to the brain. Encephalitis is an inflammation and infection of the brain (Jeong et al. 2013). The most common cause of encephalitis is a viral infection, and in rare cases it can be caused by bacteria or even fungi. Encephalitis also has two main types: primary and secondary. Primary encephalitis occurs when a virus or bacteria directly infects the brain while secondary encephalitis occurs when the infection is elsewhere in the body and then travels to the brain. Brain tumour and encephalitis both have similar and common symptoms such as convulsions, headache, nausea, unconsciousness, decreased ability to walk or balance; while some are asymptomatic and discovered incidentally. Whether it is a brain tumour or an inflammatory lesion of the brain, it affects brain cells, causing serious complications, even life-threatening. With current medical capabilities, early detection of abnormal structures in a patient’s brain can improve the likelihood of successful treatment and limit sequelae that adversely affect the patient’s brain. There are many different types of encephalitis with different causes. However, this study only focused on dealing with inflammatory lesions displayed on various types of MRI images.
