  Disorders of Health in IT Professionals   Why health disorders in the IT professionals…? ·         Stress is high in software profession because of their nature of work, target, achievements, night shift, over work load. ·         Indian IT professionals are slowly but steadily getting into modern occupational disorders. ·         Stress at work has been linked with coronary heart disease and metabolic syndrome in retrospective and prospective studies. ·         The patho physiological mechanisms involve direct neuroendocrine effects and indirect effects mediated by adverse health behaviors.   ·         The metabolic syndrome is a cluster of risk factors that increases the risk of heart disease and type 2 diabetes. ·         Characteristics of the metabolic syndrome are Ø abdominal obesity, Ø atherogenic dyslipidemia (raised triglycerides, small low-density lipoprotein particles, and low concentrations of high-density lipoprotein cholesterol), Ø high blo
  Fever: pathogenesis, patho physiology, and purpose. ·          Fever appears to have evolved in vertebrate hosts as an adaptive mechanism for controlling infection. ·          This phenomenon is produced by certain exogenous (largely microbial) stimuli that activated bone-marrow-derived phagocytes to release a fever-inducing hormone (endogenous pyrogen). ·          Endogenous pyrogen, in turn, circulates to the thermoregulatory center of the brain (preoptic area of the anterior hypothalamus) where it causes an elevation in the "set-point" for normal body temperature. ·          Warm blooded animals produced fever by increasing heat production (through shivering) or reducing heat loss (by peripheral vasoconstriction), whereas cold blooded animals do so only by behavioral mechanisms (seeking a warmer environment). Fever ·          Fever is elevated body temperature (> 37.8° C orally or > 38.2° C rectally) or an elevation above a person’s known normal daily v
