Acute bacterial sinusitis in children is diagnosed on the basis of the history, with the use of the criteria. Imaging studies (plain-film radiography, computed tomography [CT], magnetic resonance imaging [MRI], and ultrasonography) show signs of sinus inflammation but are not recommended in patients with uncomplicated infection, given the low specificity of these studies.

The tumor lysis syndrome is the most common disease-related emergency encountered by physicians caring for children or adults with hematologic cancers. This syndrome occurs when tumor cells release their contents into the bloodstream, either spontaneously or in response to therapy, leading to the characteristic findings of hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia. These electrolyte and metabolic disturbances can progress to clinical toxic effects, including renal insufficiency, cardiac arrhythmias, seizures, and death due to multiorgan failure.

Percutaneous coronary interventions (PCI) include percutaneous transluminal coronary angioplasty (PTCA) with or without stenting. Primary indications are treatment of angina pectoris (stable or unstable), myocardial ischemia, and acute MI (particularly in patients with developing or established cardiogenic shock).

The diagnosis of rheumatologic diseases is based on clinical information, blood and imaging tests, and in some cases on histology. Blood tests are useful in confirming clinically suspected diagnosis and monitoring the disease activity. The tests should be used as adjuncts to a comprehensive history and physical examination.

Thyroiditis refers to a group of inflammatory diseases affecting the thyroid gland. With the help of historical information, a physical examination and diagnostic tests, physicians can classify the type of thyroiditis and initiate appropriate treatment.
