A cricothyrotomy (also called crike, thyrocricotomy, cricothyroidotomy, inferior laryngotomy, intercricothyrotomy, coniotomy or emergency airway puncture) is an incision made through the skin and cricothyroid membrane to establish a patent airway during certain life-threatening situations, such as airway obstruction by ...

Ganglion cysts are noncancerous lumps that most commonly develop along the tendons or joints of your wrists or hands. They also may occur in the ankles and feet. Ganglion cysts are typically round or oval and are filled with a jellylike fluid. Small ganglion cysts can be pea-sized, while larger ones can be around an inch (2.5 centimeters) in diameter. Ganglion cysts can be painful if they press on a nearby nerve. Their location can sometimes interfere with joint movement. If your ganglion cyst is causing you problems, your doctor may suggest trying to drain the cyst with a needle. Removing the cyst surgically also is an option. But if you have no symptoms, no treatment is necessary. In many cases, the cysts go away on their own.

Small cell lung cancer, which occurs almost exclusively in smokers, is a malignancy characterised by rapid doubling time, high growth fraction and widespread metastasis at presentation. In this presentation, we will briefly discuss the classification of pulmonary Neuro-endocrine tumours by the World Health Organisation followed by a detailed discussion of the clinical features, lab evaluation and management of SCLC, both limited and extended stage. The frontline therapy in small cell lung cancer is etoposide and cisplatin along with thoracic radiotherapy and prophylactic cranial irradiation in patients who have a good response to therapy. Hyperfractionation of radiotherapy may provide some benefit but is also associated with increase incidence of complications. Newer agents for SCLC include Vandetanib and immunotherapy molecules, such as Iplimumab and nivolumab.

It can treat spider veins and tiny varicose veins just under the skin's surface. ... (If you have poor blood circulation feeding these tiny veins, the larger "feeder" vein must first be treated with surgery, endovenous laser or radiofrequency treatment, or sclerotherapy.)

Join the Amoeba Sisters a they explore different muscle tissues and then focus on the sliding filament theory in skeletal muscle! This video also briefly talks about muscle naming, some vocabulary (such as agonists and antagonists) before focusing on the sliding filament model. Video also mentions general roles of tropomyosin and troponin.

The spleen is an organ in the upper far left part of the abdomen, to the left of the stomach. The spleen varies in size and shape between people, but it’s commonly fist-shaped, purple, and about 4 inches long. Because the spleen is protected by the rib cage, you can’t easily feel it unless it’s abnormally enlarged. The spleen plays multiple supporting roles in the body. It acts as a filter for blood as part of the immune system. Old red blood cells are recycled in the spleen, and platelets and white blood cells are stored there. The spleen also helps fight certain kinds of bacteria that cause pneumonia and meningitis.

Fungal infections in bone marrow transplant patients. PURPOSE OF REVIEW: Invasive fungal infections have become the leading infectious cause of death in recipients of hematopoietic cell transplantation. Several factors have led to a renaissance in the study of invasive fungal infections.

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.
