Biopsy News and Research

RSS

Biopsy is the removal of cells or tissues for examination by a pathologist. The pathologist may study the tissue under a microscope or perform other tests on the cells or tissue. There are many different types of biopsy procedures. The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle. When a wide needle is used, the procedure is called a core biopsy. When a thin needle is used, the procedure is called a fine-needle aspiration biopsy.

Biomarker found in urine could help diagnose acute tubulointerstitial nephritis

In a study led by Johns Hopkins Medicine, in collaboration with Yale School of Medicine, researchers have identified a biomarker found via a simple urine test that can be used to diagnose acute tubulointerstitial nephritis (AIN), a medical condition that causes inflammation of the kidneys and can lead to acute kidney injury (AKI) — a sudden loss of kidney function.

IBD patients more likely to have a stroke than people without the disease

People with inflammatory bowel disease (IBD) are more likely to have a stroke than people without the disease, according to a study published in the June 14, 2023, online issue of Neurology, the medical journal of the American Academy of Neurology. The study does not prove that IBD causes stroke; it only shows an association.
