Diagram showing the typical location of pain [8] Signs and symptoms of acute pyelonephritis generally develop rapidly over a few hours or a day. It can cause high fever, pain on passing urine , and abdominal pain that radiates along the flank towards the back.
Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), [3] is a group of respiratory diseases affecting the interstitium (the tissue) and space around the alveoli (air sacs) of the lungs. [4] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It ...
The parenchymal cells include myocytes, and many types of specialised cells. The cells are often attached to each other and also to their nearby epithelial cells mainly by gap junctions and hemidesmosomes. There is much variation in the types of cell in the parenchyma according to the species and anatomical regions.
Glioblastomas are the most common primary malignancies to hemorrhage while thyroid, renal cell carcinoma, melanoma, and lung cancer are the most common causes of hemorrhage from metastatic disease. Other causes of intraparenchymal hemorrhage include hemorrhagic transformation of infarction which is usually in a classic vascular distribution and ...
Kidney showing circumscribed calcium deposits together with a partial stag horn calculus. Nephrocalcinosis, once known as Albright's calcinosis after Fuller Albright, is a term originally used to describe the deposition of poorly soluble calcium salts in the renal parenchyma due to hyperparathyroidism.
Acute inflammation of the lung (usually in response to pneumonia) does not cause pain unless the inflammation involves the parietal pleura, which does have pain-sensitive nerve endings. [15] Heat and redness are due to increased blood flow at body core temperature to the inflamed site.
Smoking is a known cause of some types of lung fibrosis, such as smoking-related interstitial fibrosis (SRIF). [11] Some typical connective tissue diseases [7] such as rheumatoid arthritis, ankylosing spondylitis, SLE and scleroderma; Other diseases that involve connective tissue, such as sarcoidosis and granulomatosis with polyangiitis
The chest radiograph may appear relatively normal, even late in the disease, or may suggest hyperinflation only. As the disease progresses, the chest radiograph often demonstrates diffuse, bilateral and symmetric reticulonodular opacities, cysts, bullae or a "honeycomb" (i.e., pseudo fibrotic) appearance.
