The examination room should be quiet, warm and well lit. After you have finished interviewing the patient, provide them with a gown (a.k.a. "Johnny") and leave the room (or draw a separating curtain) while they change. Instruct them to remove all of their clothing (except for briefs) and put on the gown so that the opening is in the rear. Occasionally, patient's will end up using them as ponchos, capes or in other creative ways. While this may make for a more attractive ensemble it will also, unfortunately, interfere with your ability to perform an examination! Prior to measuring vital signs, the patient should have had the opportunity to sit for approximately five minutes so that the values are not affected by the exertion required to walk to the exam room. All measurements are made while the patient is seated. Observation: Before diving in, take a minute or so to look at the patient in their entirety, making your observations, if possible, from an out-of-the way perch. Does the patient seem anxious, in pain, upset? What about their dress and hygiene? Remember, the exam begins as soon as you lay eyes on the patient. Temperature: This is generally obtained using an oral thermometer that provides a digital reading when the sensor is placed under the patient's tongue. As most exam rooms do not have thermometers, it is not necessary to repeat this measurement unless, of course, the recorded value seems discordant with the patient's clinical condition (e.g. they feel hot but reportedly have no fever or vice versa). Depending on the bias of a particular institution, temperature is measured in either Celcius or Farenheit, with a fever defined as greater than 38-38.5 C or 101-101.5 F. Rectal temperatures, which most closely reflect internal or core values, are approximately 1 degree F higher than those obtained orally. Respiratory Rate: Respirations are recorded as breaths per minute. They should be counted for at least 30 seconds as the total number of breaths in a 15 second period is rather small and any miscounting can result in rather large errors when multiplied by 4. Try to do this as surreptitiously as possible so that the patient does not consciously alter their rate of breathing. This can be done by observing the rise and fall of the patient's hospital gown while you appear to be taking their pulse. Normal is between 12 and 20. In general, this measurement offers no relevant information for the routine examination. However, particularly in the setting of cardio-pulmonary illness, it can be a very reliable marker of disease activity. Pulse: This can be measured at any place where there is a large artery (e.g. carotid, femoral, or simply by listening over the heart), though for the sake of convenience it is generally done by palpating the radial impulse. You may find it helpful to feel both radial arteries simultaneously, doubling the sensory input and helping to insure the accuracy of your measurements. Place the tips of your index and middle fingers just proximal to the patients wrist on the thumb side, orienting them so that they are both over the length of the vessel.

Influenza is a viral infection that attacks your respiratory system โ€” your nose, throat and lungs. Influenza, commonly called the flu, is not the same as stomach "flu" viruses that cause diarrhea and vomiting. For most people, influenza resolves on its own. But sometimes, influenza and its complications can be deadly. People at higher risk of developing flu complications include: Young children under 5, and especially those under 2 years Adults older than 65 Residents of nursing homes and other long-term care facilities Pregnant women and women up to two weeks postpartum People with weakened immune systems People who have chronic illnesses, such as asthma, heart disease, kidney disease and diabetes People who are very obese, with a body mass index (BMI) of 40 or higher Your best defense against influenza is to receive an annual vaccination.

Cellulitis (sel-u-LIE-tis) is a common, potentially serious bacterial skin infection. Cellulitis appears as a swollen, red area of skin that feels hot and tender. It can spread rapidly to other parts of the body. Cellulitis isn't usually spread from person to person. Skin on lower legs is most commonly affected, though cellulitis can occur anywhere on your body or face. Cellulitis might affect only your skin's surface. Or it might also affect tissues underlying your skin and can spread to your lymph nodes and bloodstream. Left untreated, the spreading infection can rapidly turn life-threatening. It's important to seek immediate medical attention if cellulitis symptoms occur.

TPE removes large-molecular-weight substances such as harmful antibodies from the plasma. It is usually carried out using an automated blood cell separator to ensure fluid balance and maintain a normal plasma volume. This may require the insertion of a femoral or jugular line to allow adequate blood flow. Typically, 30โ€“40 mL/kg of plasma (1โ€“1.5 plasma volumes) are removed at each procedure and replaced with isotonic 4.5 or 5.0% human albumin solution (some services substitute 25โ€“50% of replacement volume with 0.9% saline). Exchange with fresh frozen plasma (FFP) is reserved for the replacement of ADAMTS13 in thrombotic thrombocytopenic purpura (see below) or to replace clotting factors. A one plasma volume exchange removes about 66% of an intravascular constituent and a two plasma volume exchange approximately 85%. TPE is normally combined with disease modifying treatment, such as immunosuppressive drugs, for the underlying condition.

Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries). Narrowing of the arteries prevents normal amounts of oxygen-rich blood from reaching your kidneys. Your kidneys need adequate blood flow to help filter waste products and remove excess fluids. Reduced blood flow may increase blood pressure in your whole body (systemic blood pressure) and injure kidney tissue.

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.

Diabetic retinopathy (die-uh-BET-ik ret-ih-NOP-uh-thee) is a diabetes complication that affects eyes. It's caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). At first, diabetic retinopathy may cause no symptoms or only mild vision problems. Eventually, it can cause blindness. The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye complication.

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.
