Benign Cervical Lesions
Benign Cervical Lesions samer kareem 3,145 Views • 2 years ago

By 5 weeks' gestational age, the wolffian (ie, mesonephric) and the müllerian (ie, paramesonephric) ducts have formed from intermediate mesoderm. In the absence of testosterone and müllerian inhibitory substance, the mesonephric ducts regress and the paramesonephric ducts continue to form the female reproductive structures with fusion of the distal portions of the paramesonephric ducts to give rise to the uterine fundus, the cervix, and the upper vagina. These developmental changes are genetically controlled in large part by a series of complex transcriptional signaling pathways including Wnt signaling, Hox genes, and many others. In a female fetus, the wolffian duct disappears except for nonfunctional vestiges. The müllerian duct is lined by a columnar epithelium. This includes the entire cervix and upper vagina to the vaginal plate (ie, sinovaginal bulb). Through a process of squamous metaplasia, the vagina and a variable portion of the ectocervix become covered with squamous epithelium. This process is complete by the fifth month of pregnancy.

Temporal arteritis is a condition in which the temporal arteries, which supply blood to the head and brain, become inflamed or damaged. It is also known as cranial arteritis or giant cell arteritis. Although this condition usually occurs in the temporal arteries, it can occur in almost any medium to large artery in the body. The journal Arthritis & Rheumatology states that approximately 228,000 people in the United States are affected by temporal arteritis. According to the American College of Rheumatology, people over the age of 50 are more likely than younger people to develop the condition. Women are also more likely than men to have temporal arteritis. It is most prevalent in people of northern European or Scandinavian descent. Although the exact cause of the condition is unknown, it may be linked to the body’s autoimmune response. Also, excessive doses of antibiotics and certain severe infections have been linked to temporal arteritis. There’s no known prevention. However, once diagnosed, temporal arteritis can be treated to minimize complications.

Primary biliary cirrhosis
Primary biliary cirrhosis samer kareem 2,228 Views • 2 years ago

Primary biliary cirrhosis, sometimes called PBC, is a disease in which the bile ducts in your liver are slowly destroyed. Bile, a fluid produced in your liver, plays a role in digesting food and helps rid your body of worn-out red blood cells, cholesterol and toxins. When bile ducts are damaged, as in primary biliary cirrhosis, harmful substances can build up in your liver and sometimes lead to irreversible scarring of liver tissue (cirrhosis). Primary biliary cirrhosis is considered an autoimmune disease, in which the body turns against its own cells. Researchers think it is triggered by a combination of genetic and environmental factors. Primary biliary cirrhosis usually develops slowly and medication can slow its progression, especially if treatment begins early.
