Drowning from aspiration of water can be divided into 2 types: Freshwater (hypotonic) alters pulmonary surfactant, resulting in unstable alveoli which then collapse. The hypotonic water is absorbed into the body, leading to acute hypervolemia, hemodilution, and intravascular hemolysis. Seawater (hypertonic) draws water out of the body into the lung, causing systemic hypovolemia and hemoconcentration. The lungs become even more heavy and fluid-filled because the surfactant is essentially washed out. Only the presentation of near drowning is important to discuss because drowned victims are dead. Cyanosis, coughing, and signs of pulmonary edema, such as tachypnea, tachycardia, and blood-tinged sputum are common. Arterial blood gases show hypoxia and hypercarbia, as well as metabolic acidosis from anaerobic metabolism. Endotracheal intubation as needed Supplemental oxygen Positive pressure mechanical ventilation as needed After removal from water, the most important initial step is to establish an adequate airway. The following treatments do not help and may be harmful: Abdominal thrusts may lead to aspiration of gastric contents. As an idiosyncratic reaction, patients can develop anaphylaxis from any medication, food, insect bite, or antigenic substance entering the body by oral or parenteral route.

Typical features of Anderson lesion include disk space narrowing, focal bone destruction at the vertebral endplate adjacent to the disk, surrounding sclerosis, and local kyphosis. However, the vertebral disk is typically involved in bacterial discitis, while in Anderson lesion, the disk signal is generally preserved or shows degeneration. Moreover, perivertebral effusion and intradiscal effusion are commonly found with bacterial discitis,. Bacterial discitis high T2 signal intensity is due to hyperemia and edema, while enhancement in Anderson lesion is due to granulation tissue formation.
