Some issues Dr. Tom Deng, MD, MD MS can help you with:

Blood Transfusion

Blood transfusions typically treat those who experience a substantial loss of blood from an injury or surgical procedure, or those who suffer from conditions that alter the blood supply or blood components. For example, a blood transfusion may contribute additional red blood cells to someone with anemia, a condition where the body does not produce enough red blood cells. Other conditions may include:

Hemophilia (blood clotting disorder)
Leukemia
Liver disease
Sickle cell disease (misshapen red blood cells)
Thrombocytopenia (lack of platelets)

When a patient has sufficient blood volume and lacks one or more components, a complete blood count (CBC) test can help determine if a patient requires a transfusion by measuring four blood components: red blood cells, white blood cells, platelets, and hemoglobin. If any of the patient's component counts is significantly below a standard range, the patient will likely need a blood transfusion. The complete blood count test uses a needle to extract a small amount of blood for testing.

Blood transfusion recipients should be tested for their blood type, which is one of four different types: type A, B, AB, or O. Patients with A, B, and O blood can only receive a blood donation matching their blood type or of O blood, which is known as the universal donor. Those with AB blood are considered "universal recipients"; they may receive A, B, AB, or O blood. Further complicating blood types is the presence or absence of the RhD antigen, adding a positive or negative modifier that should also be considered. Incompatible blood donations may cause transfusion sickness, such as a hemolytic reaction, where the body fights the donated red blood cells.

In certain emergency or trauma situations, medical teams often do not perform a complete blood count (CBC) test or blood type test. In those cases, patients are often given O negative blood, which is universally accepted. Some patients have their blood type on a medical card or bracelet, allowing emergency medical teams to issue compatible blood without testing.

Transfusions are performed by inserting a needle attached to an intravenous line (IV) into a vein in the body. This IV line is attached to a bag of blood that steadily dispenses blood into the patient's bloodstream. The type, volume, and components of donated blood depend on the patient's condition and needs. After the transfusion is complete, patients are generally permitted to resume normal activity, unless prohibited by a condition or injury. Some patients may experience bruising or soreness around the area that the needle was inserted.

At times, a second complete blood count test is performed to determine if the transfusion has brought patients' component counts to normal levels. Some patients may require multiple blood transfusions to reach a healthy blood volume and blood component count.

Once patients' blood volumes and components reach sufficient levels, they will generally begin to feel better. Patients of all ages, from newborn infants to elderly adults, can receive a blood transfusion.

Mononucleosis (Mono)

Mononucleosis, frequently called ''mono,'' is a viral infection that causes fatigue, fever, swollen lymph glands, and sore throat. The Epstein-Barr virus (EBV), spread through saliva, is the primary virus that leads to mono. Mono is most common in teenagers and young adults, where EBV is often transmitted through kissing or sharing drinks. For this reason, mono is colloquially referred to as ''the kissing disease.'' Mononucleosis usually resolves on its own; however, recovery from mono can take from several days to several weeks. Some young adults may continue to experience extreme fatigue from mono for months, often requiring a semester home from school.

Mononucleosis happens in three stages:

During the initial stage, those with mono may experience few symptoms as EBV replicates in the body. Symptoms such as headaches and body aches are often misattributed to allergies or stress. People with mono may continue performing their daily activities and attending school, leading to increased transmission of the virus to others. The initial stage lasts for about five to fourteen days.

During the acute stage, mono symptoms intensify and may include the enlargement of the spleen, a sore throat, fatigue, liver issues, and skin rashes. The mono infection is at its worst in this stage.

Lastly, the convalescent stage is when recovery begins. This period of healing can last from two to six months.

Mono can be detected by a physical exam; physicians can diagnose mono by checking for inflamed lymph nodes, tonsils, or spleens. Blood antibody tests may also help diagnose mono by revealing antibodies in the blood that were formed as a response to the Epstein-Barr virus. Elevated levels of white blood cells can also suggest that a patient has mono.

There are no medications specifically for mono or the Epstein-Barr virus, and patients are advised to rest and avoid strenuous exercise. Drinking plenty of fluids, eating a healthy diet, and taking anti-inflammatory ibuprofen (motrin) may also help people who are afflicted with mono feel better.

People with mono should take precautions to avoid spreading the condition to others. They can prevent infection by not sharing glasses, food, and utensils with others until they fully recover.

Urodynamics (Bladder and Urethra Function Test)

Urodynamics are tests that assess how well the lower urinary tract is functioning. Specifically, they evaluate its ability to hold and release urine, as well as show if any blockages or leaks are present. The lower urinary tract is made up of the following:

The bladder, which stores urine.
The urinary sphincters, which are muscles around the opening of the bladder that hold urine in.
The urethra, which is the tube where urine flows out of the body.

Urodynamics tests are normally performed together as one series, but depending on patients' symptoms, only one or some of them may be necessary. The most common tests are:

Cystometrogram, which measures the amount of urine the bladder can store and how full it is before someone has the urge to urinate. Doctors may order this test if she suspects their patient has a weak bladder.
Pressure flow study, which measures the pressure in the bladder while urinating. This test helps locate a blockage in the bladder.
Uroflowmetry, which measures how much and how fast urine flows out of the body. This test is usually recommended when patients have difficulty urinating or they have a slow stream.
Urethral sphincter electromyography, which measures how strong the muscles and nerves in the bladder and sphincters are. Doctors may request this test if the problem they are experiencing is linked to muscle or nerve damage in the lower urinary tract.
Urethral pressure profile, which measures the pressure along the urethra while the bladder is gradually filled with fluid. Low pressure could mean someone has a weak urethra, a contributing factor to urinary incontinence (loss of bladder control).

For a few hours following a urodynamics study, patients will likely feel some soreness or discomfort. It is recommended to drink at least one glass of water every half hour for two hours to relieve these symptoms. Holding a warm, moistened washcloth over the area where discomfort is felt or taking a warm bath may also help. Results for cystrometrograms and uroflowmetry are typically available immediately after the test, but results for the other tests may take a few days. When doctors have reviewed a patient's test results, he or she will discuss them with the patient, along with any treatments the patient may need.
