In COVID-19, the arterial and general tissue oxygen levels can drop without any initial warning.The chest x-ray may show diffuse pneumonia.Cases of silent hypoxia with COVID-19 have been reported for patients who did not experience shortness of breath or coughing until their oxygen levels had depressed to such a degree that they were at risk of acute respiratory distress (ARDS) and organ failure.
Ureterovesicular junction obstruction (UVJ obstruction) is an obstruction at the level of the ureter and bladder. It accounts for 20% of cases of hydronephrosis detected in utero. It is also most commonly seen in males and involved both sides of the urinary tract in approximately 25% of cases. [1]
The signs and symptoms of hydronephrosis depend upon whether the obstruction is acute or chronic, partial or complete, unilateral or bilateral. Hydronephrosis that occurs acutely with sudden onset (as caused by a kidney stone) can cause intense pain in the flank area (between the hips and ribs) known as a renal colic. Historically, this type of ...
Hydronephrosis is seen as an anechoic fluid-filled interconnected space with enhancement within the renal sinus, and normally, the dilated pelvis can be differentiated from the dilated calyces.

A person with an acute febrile respiratory illness with clinical, radiological, or histopathological evidence of pulmonary parenchymal disease (e.g., pneumonia or acute respiratory distress Syndrome), an inconclusive MERS-CoV laboratory test (that is, a positive screening test without confirmation), and a resident of or traveler to Middle ...
There are three stages, according to the way COVID-19 infection can be tackled by pharmacological agents, in which the disease can be classified. [71] Stage I is the early infection phase during which the domination of upper respiratory tract symptoms is present.
There are roughly 450 million cases of pneumonia every year. Of those case, viral pneumonia counts for about 200 million cases which includes about 100 million children and 100 million adults. [14] Viral pneumonia is more prevalent in the very young, less than 5 years old, and in the very old, more than 75 years old.
Pulmonary edema can cause permanent organ damage, and when sudden (acute), can lead to respiratory failure or cardiac arrest due to hypoxia. [7] The term edema is from the Greek οἴδημα ( oidēma , "swelling"), from οἰδέω ( oidéō , "(I) swell").
