This animation describes what anti-TNF-alpha therapies are, how they work, and how patients with inflammatory bowel disease (IBD) can benefit.

Venipuncture can be a challenging process for medical professionals especially when a patients veins are difficult to see. VeinViewer uses near infrared light to create a digital image of patient vasculature in real time.

If you have gestational diabetes, your baby may be at increased risk of: Excessive birth weight. Extra glucose in your bloodstream crosses the placenta, which triggers your baby's pancreas to make extra insulin. This can cause your baby to grow too large (macrosomia).

Achalasia is a neurogenic esophageal motility disorder characterized by impaired esophageal peristalsis and a lack of lower esophageal sphincter relaxation during swallowing. Symptoms are slowly progressive dysphagia, usually to both liquids and solids, and regurgitation of undigested food. Evaluation typically includes manometry, barium swallow, and endoscopy. Treatments include dilation, chemical denervation, surgical myotomy, and peroral endoscopic myotomy.

Learn what tests can be used to screen and diagnose syphilis as well as how to treat and prevent the infection.

A ganglion cyst is a tumor or swelling on top of a joint or the covering of a tendon (tissue that connects muscle to bone). It looks like a sac of liquid (cyst). Inside the cyst is a thick, sticky, clear, colorless, jellylike material. Depending on the size, cysts may feel firm or spongy.

The dental implant, usually a cylindrical and/or tapered post made of titanium, is placed surgically into the jawbone. As you heal, your implant will osseointegrate, or fuse with, your natural jawbone, with the two growing together to form a strong and long-lasting foundation for your replacement teeth.

Your body needs bile, but if it has too much cholesterol in it, that makes gallstones more likely. It can also happen if your gallbladder can't empty properly. Pigment stones are more common in people with certain medical conditions, such as cirrhosis (a liver disease) or blood diseases such as sickle cell anemia.

A bone marrow biopsy removes a small amount of bone and a small amount of fluid and cells from inside the bone (bone marrow). A bone marrow aspiration removes only the marrow. These tests are often done to find the reason for many blood disorders and may be used to find out if cancer or infection has spread to the bone marrow. Bone marrow aspiration removes a small amount of bone marrow fluid and cells through a needle put into a bone. The bone marrow fluid and cells are checked for problems with any of the blood cells made in the bone marrow. Cells can be checked for chromosome problems. Cultures can also be done to look for infection. A bone marrow biopsy removes bone with the marrow inside to look at under a microscope. The aspiration (taking fluid) is usually done first, and then the biopsy.

Buerger's disease (thromboangiitis obliterans) is a rare disease of the arteries and veins in the arms and legs. In Buerger's disease, your blood vessels become inflamed, swell and can become blocked with blood clots (thrombi). This eventually damages or destroys skin tissues and may lead to infection and gangrene. Buerger's disease usually first shows in your hands and feet and may eventually affect larger areas of your arms and legs. Virtually everyone diagnosed with Buerger's disease smokes cigarettes or uses other forms of tobacco, such as chewing tobacco. Quitting all forms of tobacco is the only way to stop Buerger's disease. For those who don't quit, amputation of all or part of a limb is sometimes necessary.

A diagnosis of sarcoidosis is established on the basis of compatible clinical and radiologic findings and histologic evidence of the presence of noncaseous epithelioid cell granulomas in one or more organs and the absence of causative organisms or particulates (16). Granulomas of known causes and local sarcoidlike reactions must be excluded. Granulomatous lesions may result from many conditions, including tuberculosis, berylliosis, leprosy, hypersensitivity pneumonitis, Crohn disease, primary biliary cirrhosis, and fungal disease. Moreover, local sarcoidlike reactions may be seen in lymph nodes that drain a neoplasm or a site of chronic inflammation (19). Such reactions also have been seen in patients who have undergone chemotherapy and radiation therapy (23). If biopsy of lymph nodes or pulmonary or pleural tissue is necessary for diagnosis, one of three techniques may be used: transbronchial biopsy, CT-guided biopsy, or surgical biopsy (24). The use of a surgical technique may be warranted when the results of biopsy with another procedure are not definitive and biopsy of mediastinal lymph nodes, lung, or both is required. This can generally be done with minimally invasive procedures, such as cervical mediastinoscopy, the Chamberlain procedure (a parasternal minithoracotomy for biopsy of the aortopulmonary window or para-aortic nodes), or video-assisted thoracoscopic surgical biopsy (25).
