ALL CAUSES BEGINNING WITH THE LETTER U:

ULCERATIVE COLITIS / UC AWARENESS RIBBON COLOR:

Purple Awareness Ribbons for Ulcerative Colitis / UC

Ulcerative Colitis is also known as:
• Chronic Non-Specific Ulcerative Colitis
• Colitis Gravis
• Idiopathic Non-Specific Ulcerative Colitis
• Inflammatory Bowel Disease (IBD), Ulcerative Colitis Type
• Proctocolitis, Idiopathic

What is Ulcerative Colitis?
Ulcerative Colitis is an inflammatory bowel disease (IBD) of unknown cause. It is characterized by chronic inflammation and ulceration of the lining of the major portion of the large intestine. In most affected individuals, the lowest region of the large intestine, known as the rectum, is initially affected. As the disease progresses, some or all, of the colon may become involved. Although associated symptoms and findings usually become apparent during adolescence or young adulthood, some individuals may experience an initial episode between ages 50 to 70. In other cases, symptom onset may occur as early as the first year of life. Ulcerative colitis is usually a chronic disease with repeated episodes of symptoms and remission.

UNDIAGNOSED DISEASES AWARENESS RIBBON COLOR:

UNDIFFERENTIATED CONNECTIVE TISSUE DISEASE AWARENESS RIBBON COLOR:

Zebra Awareness Ribbons for Undifferentiated Connective Tissue Disease

Undifferentiated Connective Tissue Disease (UCTD) is also known as:
• Chronic Non-Specific Ulcerative Colitis
• Colitis Gravis
• Idiopathic Non-Specific Ulcerative Colitis
• Inflammatory Bowel Disease (IBD), Ulcerative Colitis Type
• Proctocolitis, Idiopathic

What is Undifferentiated Connective Tissue Disease (UCTD)?
The term Undifferentiated Connective Tissue Disease (UCTD) is used to describe a condition in people who have symptoms and lab test results that indicate a systemic autoimmune disorder or connective tissue disease, but which do not meet enough such characteristics to indicate a diagnosis for a well-defined connective tissue disease such as Rheumatoid Arthritis, Systemic Lupus Erythematosus or Scleroderma.

Although the word "undifferentiated" sounds vague, it describes a real problem. This undifferentiated category is distinctly separate from another group of vague-sounding disorders called Overlap Syndromes. People with Overlap Syndromes have the clear features of at least two or more Connective Tissue Diseases, and thus may meet the diagnoses for several at the same time. In contrast, patients with Undifferentiated Connective Tissue Disease do not have enough of the features of a definite Connective Tissue Disease to be firmly classified with such a diagnosis. However, because they may have a few features from several known diseases, they are said to be "undifferentiated."

UNKNOWN PRIMARY CARCINOMA, ADULT AWARENESS RIBBON COLOR:

Zebra Awareness Ribbons for Unknown Primary Carcinoma, Adult

What is Unknown Primary Carcinoma of, Adult?
Unknown Primary Carcinoma is a diagnosis given when doctors cannot determine where a cancer began. Carcinoma of unknown primary is rare, and it can be an aggressive type of cancer. Cancers form from mutated cells in one area of the body and can metastasize to other areas. In Carcinoma of Unknown Primary, the metastasized cells are discovered, but the tumor where they began cannot be found.

UPPER RESPIRATORY INFECTIONS (CATS) AWARENESS RIBBON COLOR:

Animal Paw Prints Awareness Ribbons for Upper Respiratory Infection (Cats)

Feline Upper Respiratory Infection (URI) is the common term for a respiratory infection caused by one or more viral or bacterial agents that are capable of causing disease in cats. The most common viruses that cause upper respiratory infections in cats are Feline Herpesvirus Type-1 (also known as feline viral rhinotracheitis or FVR) and Feline Calicivirus (FCV), while the most common bacteria that cause upper respiratory infections in cats are Bordetella bronchiseptica (B. bronchiseptica) and Chlamydophila felis (C. felis).

URACHAL CANCER AWARENESS RIBBON COLOR:

Zebra Awareness Ribbons for Urachal Cancer

Urachal Cancer is also known as:
• Urachal Adenocarcinoma
• Urachal Carcinoma

What is Urachal Cancer?
Urachal Cancer is a form of cancer that arises in a structure called the urachus. The urachus is a canal that exists when the fetus is developing before birth. This canal runs from the bladder of the fetus to the belly button. Between the fourth and fifth month of pregnancy, this canal breaks down into a fibrous band of tissue called a ligament. This ligament runs from the belly button to the top of the bladder and is called the median umbilical ligament. Sometimes, there are tissue remnants of the urachus in adults and these remnants can potentially become cancerous. Urachal cancer will often extend into surrounding structures like the bladder, and can potentially spread to other areas of the body.

What is Urethral Cancer?
Urethral Cancer is a disease in which malignant cells form in the tissues of the urethra. The urethra is the tube that carries urine from the bladder to outside the body.

UROFACIAL SYNDROME AWARENESS RIBBON COLOR:

Blue Jeans Awareness Ribbons for Urofacial Syndrome - Listed by Global Genes®
Urofacial Syndrome is a rare disease. Rare diseases are also represented by Zebra Ribbons.

Urofacial Syndrome (UFS) is also known as:
• Hydronephrosis with Peculiar Facial Expression
• Inverted Smile and Occult Neuropathic Bladder
• Ochoa Syndrome
• Partial Facial Palsy with Urinary Abnormalities
• UFS

What is Urofacial Syndrome (UFS)?
Urofacial Syndrome (UFS) is an extremely rare inherited disorder characterized by an unusual facial expression and disorder of the urinary tract. When the bladder tries to empty, the outlet closes, meaning that the urine goes back towards the kidneys rather than out of the body. This problem can be present at birth. When affected infants smile, their facial musculature turns upside down or “inverts” so that they appear to be grimacing or crying.

URTICARIA AWARENESS RIBBON COLOR:

Red and White Polka Dots Awareness Ribbons for Urticaria

What is Urticaria?
Urticaria is a chronic, reactive skin disorder. It is probably the most common form of physical urticaria (hives). Major symptoms may include abnormal reddening of the skin, hives and itching after exposure of the skin to cold temperatures.

There are two forms of the disorder: Essential (acquired) Cold Urticaria, and Familial (hereditary) Cold Urticaria. The symptoms of the acquired form become obvious in two to five minutes after exposure to the triggering substance or situation, while it takes 24 to 48 hours for symptoms of familial cold urticaria to appear. Symptoms also tend to last longer with the familial form, typically about 24 hours although they may remain for as long as 48 hours. With the acquired form, symptoms tend to last for one to two hours.

URTICARIAL VASCULITIS AWARENESS RIBBON COLOR:

Red Awareness Ribbons for Urticarial Vasculitis

What is Urticarial Vasculitis?
Urticarial Vasculitis is a variant of cutaneous small vessel vasculitis. It is characterised by inflamed and reddened patches or wheals on the skin that appear to resemble urticaria, but when the skin is examined closely under a microscope, a vasculitis is found.

Urticarial Vasculitis is generally classified as two types: Normocomplementaemic Urticarial Vasculitis and Hypocomplementaemic Urticarial Vasculitis. These are distinguished by finding normal or lowered levels of complement proteins on blood testing. Although both types may be associated with systemic symptoms such as angioedema, abdominal or chest pain, fever, and joint pain, this is more apparent in the hypocomplementaemic form. This form has also been linked to the connective tissue disease Systemic Lupus Erythematosus (SLE).
