These air sacs make up most of the lung tissue. Lung diseases affecting the alveoli include: Pneumonia: An infection of the alveoli, usually by bacteria. Tuberculosis: A slowly progressive pneumonia caused by the bacteria Mycobacterium tuberculosis. Chronic respiratory diseases are chronic diseases of the airways and other structures of the lung. Some of the most common are: asthma, chronic obstructive pulmonary disease, occupational lung diseases and pulmonary hypertension.
Patients are generally placed in a supine position with the head in an extended position. As noted above, Gardner-Wells tongs can be used for additional cervical traction. The hands can also be tied downward to increase the operative exposure. Once the surgical site is properly prepared with cleansing material, the appropriate surgical level is identified with intraoperative radiographs. A scalpel is used to make a linear longitudinal incision just medial to the body of the sternocleidomastoid muscle. The incision is made long enough to include at least 2 vertebral levels if a 1-level discectomy is being performed. Alternatively, transverse skin incisions over the targeted vertebral level can also be performed. The platysmal muscle is identified and incised. The platysmal incision can be extended if a multilevel decompression is the surgical aim. Extensive subplatysmal dissection is performed to reduce retraction injury.
What is the spleen and what causes an enlarged spleen (splenomegaly)? The spleen sits under your rib cage in the upper left part of your abdomen toward your back. It is an organ that is part of the lymph system and works as a drainage network that defends your body against infection. White blood cells produced in the spleen engulf bacteria, dead tissue, and foreign matter, removing them from the blood as blood passes through it. The spleen also maintains healthy red and white blood cells and platelets; platelets help your blood clot. The spleen filters blood, removing abnormal blood cells from the bloodstream. A spleen is normally about the size of your fist. A doctor usually can't feel it during an exam. But diseases can cause it to swell and become many times its normal size. Because the spleen is involved in many functions, many conditions may affect it.
If you’re like me, you probably hook your chest tube up to a Pleur-Evac, put it on the ground, then back away slowly. Who knows what goes on in that mysterious bubbling white box? Hopefully this will post shed some light. Isn’t this just a container for stuff that comes out of the chest? Why does it look so complicated? It’s complicated because the detection/collection of air and fluid require different setups. Most commercial models also allow you to hook the drainage system to wall suction, so you can quickly evacuate the pleural space. This requires its own setup. Because of the need to juggle air, fluid and suction, the most common commercial system includes 3 distinct chambers. If you were to simplify the device, or build one out of spare bottles and tubes, it might look like this:
A plastic surgeon in China has successfully grown an artificial ear on a man's arm in a pioneering medical procedure. The patient, surnamed Ji, lost his right ear in an accident and yearned to have it back. Doctor Guo Shuzhong from a hospital in Xi'an, China's Shaanxi Province, used Mr Ji's cartilage from his ribs to build the new ear; and he expects to transplanted the organ to the man's head in about four months. According to the Huanqiu report, Mr Ji sustained serious injuries in the right side of his face in a traffic accident about a year ago. His right ear was torn from his face. The man, whose age is not specified, has since received multiple surgical operations to restore his facial skin and his cheeks. However, he felt frustrated about losing his right ear for good. The patient told a report from China News: 'I lost one ear. I have always felt that I am not complete.' Having sought medical advice from multiple sources, Ji realised that it was impossible to restore his ear through conventional medical procedures as a substantial part of his right ear had gone missing. Upon hearing recommendations, Mr Ji went to see doctor Guo Shuzhong, who works at the First Affiliated Hospital of Xi'an Jiaotong University in the city of Xi'an. Doctor Guo, a renowned plastic surgeon, conducted China's first face transplant operation in 2006, according to China Daily.
