Immunosuppression weakens the body's immune system, making it less effective at fighting off pathogens. As a result, infections from bacteria, viruses, fungi, and parasites are the most frequent and significant complications experienced by individuals receiving immunosuppressive therapy, such as organ transplant recipients or those with autoimmune diseases.

In epidemiology, incidence refers to the number of new cases of a disease or condition that occur within a specific time frame in a defined population. Dental caries, also known as tooth decay, is a common chronic condition where bacteria in the mouth produce acids that destroy the tooth enamel and underlying dentin, leading to cavities. The incidence of dental caries would be the number of new cases of tooth decay diagnosed within a given period, say a year or another time interval.

Point prevalence, on the other hand, is the proportion of a population that has a specific condition at a particular point in time. It is a measure of the prevalence of dental caries at a single moment, which does not account for new cases or recoveries.

Period prevalence is the proportion of the population that has had a particular condition during a specific period of time, such as a year or a month. This measure includes both new cases and cases that have persisted from before the start of the period in question.

Brown tumors are benign bone lesions that result from the effect of parathyroid hormone (PTH) on bone tissue in patients with hyperparathyroidism. Increased PTH causes bone resorption by stimulating osteoclastic activity. Hyperparathyroidism is associated with increased PTH levels and hypercalcemia.
