Current Trends in Quarantine Entomology

With world trade in agricultural commodities increasing, the introduction of exotic insects into new areas where they become pests will increase. The development and application of quarantine treatments or other mitigation approaches to prevent pest introduction in traded commodities raise many research and regulatory issues. The probit 9 standard for quarantine treatment efficacy has given way to risk-based alternatives. Varietal testing may have merit for some treatments or commodities but not for others. Development of generic treatments to control broad groups of insects or insects in all commodities can expedite new trade in agricultural products. Area-wide pest management programs lower pest levels before harvest and improve the quarantine security provided by any post-harvest treatments. Systems approaches capitalize on cumulative pest mortality from multiple control components to achieve quarantine security in an exported commodity. Certain quarantine treatment technologies such as irradiation are not universally accepted, which is slowing their adoption. Standardized phytosanitary measures and research protocols are needed to improve the flow of information when countries propose to trade in a regulated commodity

Diagnostic aids for detection of oral precancerous conditions

Oral cancer has a tendency to be detected at late stage which is detrimental to the patients because of its high mortality and morbidity rates. Early detection of oral cancer is therefore important to reduce the burden of this devastating disease. In this review article, the most common oral precancerous lesions are discussed and the importance of early diagnosis is emphasized. In addition, the most common non-invasive oral cancer devices that can aid the general practitioners in early diagnosis are also discussed

Classification and Etiopathogenesis of Hypothyroidism

Hypothyroidism is a graded phenomenon characterized by a deficient thyroidal production of thyroid hormone. This condition comprises multiple functional or structural disorders, both congenital and acquired. The clinical expression of hypothyroidism varies between individuals, depending on the cause, duration, and severity of the hypothyroid state, but almost all organs and systems may be affected by a deficiency of thyroid hormone production. This chapter describes the epidemiology, multiple etiologies, and clinical manifestations of hypothyroidis
