Mastocytosis, a type of mast cell disease, is a rare disorder affecting both children and adults caused by the accumulation of functionally defective mast cells and CD34+ mast cell precursors.
Nail clubbing, also known as digital clubbing or clubbing, is a deformity of the finger or toe nails associated with a number of diseases, mostly of the heart and lungs. When it occurs together with joint effusions, joint pains, and abnormal skin and bone growth it is known as hypertrophic osteoarthropathy.
Panniculitis is a group of diseases whose hallmark is inflammation of subcutaneous adipose tissue. Symptoms include tender skin nodules, and systemic signs such as weight loss and fatigue.
Lymphadenopathy or adenopathy is disease of the lymph nodes, in which they are abnormal in size or consistency. Lymphadenopathy of an inflammatory type is lymphadenitis, producing swollen or enlarged lymph nodes. In clinical practice, the distinction between lymphadenopathy and lymphadenitis is rarely made and the words are usually treated as synonymous. Inflammation of the lymphatic vessels is known as lymphangitis. Infectious lymphadenitis affecting lymph nodes in the neck is often called scrofula.
Hepatosplenomegaly is the simultaneous enlargement of both the liver (hepatomegaly) and the spleen (splenomegaly). Hepatosplenomegaly can occur as the result of acute viral hepatitis, infectious mononucleosis, and histoplasmosis or it can be the sign of a serious and life-threatening lysosomal storage disease. Systemic venous hypertension can also increase the risk for developing hepatosplenomegaly, which may be seen in those patients with right-sided heart failure.
Myopathy is a disease of the muscle in which the muscle fibers do not function properly. This results in muscular weakness. Myopathy means muscle disease. This meaning implies that the primary defect is within the muscle, as opposed to the nerves or elsewhere. Muscle cramps, stiffness, and spasm can also be associated with myopathy.
Aphthous stomatitis is a common condition characterized by the repeated formation of benign and non-contagious mouth ulcers (aphthae) in otherwise healthy individuals. The informal term canker sores is also used, mainly in North America, although this may also refer to any mouth ulcers.
Necrotizing enterocolitis (NEC) is a medical condition where a portion of the bowel dies. It typically occurs in newborns that are either premature or otherwise unwell. Symptoms may include poor feeding, bloating, decreased activity, blood in the stool, or vomiting of bile.
A systemic disease is one that affects a number of organs and tissues, or affects the body as a whole.
Mixed connective tissue disease commonly abbreviated as MCTD, is an autoimmune disease characterized by the presence of high blood levels of a specific autoantibody, now called anti-U1 ribonucleoprotein (RNP). The idea behind the "mixed" disease is that this specific autoantibody is also present in other autoimmune diseases such as systemic lupus erythematosus, polymyositis, scleroderma, etc. It was characterized in 1972, and the term was introduced by Leroy in 1980.
Bovine alphaherpesvirus 5 is a virus species of the genus Varicellovirus and subfamily Alphaherpesvirinae. It causes meningoencephalitis and respiratory disease in cattle and sheep. As with all herpes viruses latent infection can occur, with recrudescence at times of stressed and/or immunosuppression. Sites of latency include the CNS and mucosae of the nose and trachea. The disease has been documented in South America, the United States, Australia, Germany and Hungary. Caused by: BHV-5 — Bovine Encephalitis Virus — Bovine Encephalitis Herpesvirus
Intermediate uveitis is a form of uveitis localized to the vitreous and peripheral retina. Primary sites of inflammation include the vitreous of which other such entities as pars planitis, posterior cyclitis, and hyalitis are encompassed. Intermediate uveitis may either be an isolated eye disease or associated with the development of a systemic disease such as multiple sclerosis or sarcoidosis. As such, intermediate uveitis may be the first expression of a systemic condition. Infectious causes of intermediate uveitis include Epstein-Barr virus infection, Lyme disease, HTLV-1 virus infection, cat scratch disease, and hepatitis C.
Band keratopathy is a corneal disease derived from the appearance of calcium on the central cornea. This is an example of metastatic calcification, which by definition, occurs in the presence of hypercalcemia.
Lupus erythematosus is a collection of autoimmune diseases in which the human immune system becomes hyperactive and attacks healthy tissues. Symptoms of these diseases can affect many different body systems, including joints, skin, kidneys, blood cells, heart, and lungs. The most common and severe form is systemic lupus erythematosus.
Systemic lupus erythematosus (SLE), also known simply as lupus, is an autoimmune disease in which the body's immune system mistakenly attacks healthy tissue in many parts of the body. Symptoms vary between people and may be mild to severe. Common symptoms include painful and swollen joints, fever, chest pain, hair loss, mouth ulcers, swollen lymph nodes, feeling tired, and a red rash which is most commonly on the face. Often there are periods of illness, called flares, and periods of remission during which there are few symptoms.
Scleroderma is a group of autoimmune diseases that may result in changes to the skin, blood vessels, muscles, and internal organs. The disease can be either localized to the skin or involve other organs in addition to the skin. Symptoms may include areas of thickened skin, stiffness, feeling tired, and poor blood flow to the fingers or toes with cold exposure. One form of the condition, known as CREST syndrome, classically results in calcium deposits, Raynaud's syndrome, esophageal problems, thickening of the skin of the fingers and toes, and areas of small dilated blood vessels.
For women with systemic lupus erythematosus (SLE), pregnancy can present some particular challenges for both mother and child.
Borsieri’s sign or Borsieri’s line is a dermatological sign that consists of pressure by a sharp object producing a white line on the skin that quickly turns red. It is present in scarlet fever. It was first described by French physician Giovanni Battista Borsieri de Kanifeld.
Daniel Braverman is an American football wide receiver for the Calgary Stampeders of the Canadian Football League (CFL). He played college football at Western Michigan. He was drafted by the Chicago Bears in the seventh round of the 2016 NFL Draft.
Oral manifestations of systematic disease are signs and symptoms of disease occurring elsewhere in the body detected in the oral cavity and oral secretions. High blood sugar can be detected by sampling saliva. Saliva sampling may be a non-invasive way to detect changes in the gut microbiome and changes in systemic disease. The association between the salivary microbiome and with Polycystic Ovarian Syndrome has been characterized. "[S]aliva microbiome profiles correlate with those in the stool, despite the fact that the bacterial communities in the two locations differ greatly. Therefore, saliva may be a useful alternative to stool as an indicator of bacterial dysbiosis in systemic disease." Another example is tertiary syphilis, where changes to teeth can occur. Syphilis infection can be associated with longitudinal furrows of the tongue.
