Necrotizing ragged ulceration with no apparent inflammatory response is indicative of agranulocytosis.
Explanation:
It is caused by a gram-negative fungus: This statement is not true. Thrush is caused by Candida albicans, which is a yeast (fungus) but not a gram-negative organism. In fact, fungi are not classified as gram-positive or gram-negative in the same way that bacteria are. Candida is a eukaryotic organism and does not fit into the gram classification system.
It is characterized by a plaque of proliferating epithelial and other cells: This statement is true. Thrush presents as white patches or plaques in the oral cavity, which consist of fungal elements, dead epithelial cells, and inflammatory cells.
It is a complication of immunosuppression or systemic disease: This statement is true. Thrush is commonly seen in individuals who are immunocompromised, such as those with HIV/AIDS, cancer patients undergoing chemotherapy, or individuals on long-term corticosteroid therapy.
It can affect neonates in an epidemic fashion: This statement is true. Thrush can indeed affect neonates, particularly those born to mothers with vaginal candidiasis, and outbreaks can occur in neonatal intensive care units.
Lead is the most commonly used substance for protection against X-ray radiation.
