Status epilepticus is a serious seizure disorder in which seizures do not stop. A seizure is a sudden disruption of the brain's normal electrical activity, which can cause a loss of consciousness and make the body twitch and jerk. This condition is a medical emergency.
Steatocystoma multiplex: A rare inherited disorder characterized by numerous skin cysts that may contain a thick substance called sebum. The cysts occur mainly on the chest, abdomen and front of neck.
Steatocystoma multiplex - natal teeth: A rare inherited disorder characterized by the presence of teeth at birth and the development of numerous skin cysts that may contain a thick substance called sebum. The cysts occur mainly on the chest, abdomen and front of neck.
Steinfeld syndrome: A very rare syndrome characterized by kidney abnormalities, single brain lobe and a heart defect.
Stenotrophomonas maltophilia: A bacteria that is usually found in aquatic environments, is not very virulent and rarely infects humans. Most cases of infection tends to occur through use of hospital appliances such as catheters, I.V lines and breathing tubes in immunocompromised people.
Sterility due to immotile flagella (medical condition): A very rare disorder where the cilia fail to move. The cilia are tiny, hair-like structures found in the respiratory and ear passages and help to clear debris and mucus. This results in increases risk of respiratory infections, sinusitis, ear infections and male infertility. The infertility results as the tails of sperm is basically cilia.
Stern Lubinsky Durrie syndrome (medical condition): A very rare syndrome characterized mainly by thick, scaly skin on the palms and soles, corneal changes and dental problems.
Sternal cleft: A rare birth defect where there is a cleft or a groove in the sternum which is the bone in the middle of the chest wall that joins the two sides of the rib cage. The cleft may be partial or complete.
Sternal cyst - vascular anomalies: A rare disorder involving blood vessel anomalies and a cyst in the sternum.
Sternal malformation vascular dysplasia association: A rare disorder characterized by a cleft of the sternum and facial hemangiomata.
Steroid dehydrogenase deficiency - dental anomalies: A very rare liver disease involving an enzyme (steroid dehydrogenase) deficiency and dental anomalies.
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are mucocutaneous drug-induced or idiopathic reaction patterns characterized by skin tenderness and erythema of skin and mucosa, followed by extensive cutaneous and mucosal exfoliulltion and are potentially life-threatening due to multi system involvement. SJS has been classified as a severe expression of erythema multiforme (EM), and is sometimes referred to as erythema multiforme major . The Stevens Johnson Syndrome Foundation said they have seen a rise in the disease involving children and ibuprofen use during 2004, but the disease is still not well known.
Stewart-Treves syndrome: A rare malignant tumor that tends to occur as a complication of chronic lymph gland blockage such as can occur after a mastectomy to remove breast cancer.
Stickler Syndrome, type I: A rare genetic disorder characterized by joint problems, distinctive facial characteristics and eye and ear abnormalities. Type 1 is caused by a genetic defect on chromosome 12q13.11-q13.2.
Stickler Syndrome, type II: A rare genetic disorder characterized by joint problems, distinctive facial characteristics and eye and ear abnormalities. Type 2 is caused by a genetic defect on chromosome 1p21.
Stickler Syndrome, type III: A rare genetic disorder characterized by joint problems, distinctive facial characteristics and ear abnormalities. Type 3 is caused by a genetic defect on chromosome 6q21.3. Type 3 doesn't involve any of the eye problems that occur in type 1 and 2.
Stiff skin syndrome (medical condition): A rare inherited disorder characterized mainly by very stiff, thick skin that can affect the ability to move joints
Stiff person syndrome (SPS) (or stiff-man syndrome outside the USA) is a rare neurologic disorder of unknown etiology.
Still's disease, a disorder featuring inflammation, is characterized by high spiking fevers, evanescent (transient) salmon-colored rash, and/or arthritis. Still's disease was first described in children, but it is now known to occur, much less commonly, in adults (in whom it is referred to as adult-onset Still's disease).
A rare disorder characterized by dwarfism, diabetes, small head and high levels of alanine in the urine
A very rare inherited disorder characterized mainly by mental retardation, short stature and congenital hip dislocation.
A very rare disorder involving abnormal jaw development and unerupted permanent teeth
A very rare syndrome characterized mainly by mental retardation and eye movement problems (Duane anomaly).
A very rare syndrome characterized mainly by muscle, skin, sweating, tooth and facial abnormalities
A very rare syndrome characterized mainly by short stature, mental retardation and wide set eyes
A syndrome characterised by the occurrence of cardiac arrhythmia, perodactyly, and Robin sequence
This syndrome is characterised by phocomelia (involving arms more severely), ectrodactyly, ear anomalies (bilateral anomalies of the pinnae), conductive deafness, dysmorphism (long and prominent philtrum, mild maxillary hypoplasia) and sinus arrhythmia
Stomach cancer is cancer that occurs in the stomach — the muscular sac located in the upper middle of your abdomen, just below your ribs. It occurs due to abnormal and uncontrolled cell growth in the stomach. Your stomach receives and holds the food you eat and then helps to break down and digest it.
Another term for stomach cancer is gastric cancer. These two terms most often refer to stomach cancer that begins in the mucus-producing cells on the inside lining of the stomach (adenocarcinoma). Adenocarcinoma is the most common type of stomach cancer.
Stomach cancer is uncommon in the United States, and the number of people diagnosed with the disease each year is declining. Stomach cancer is much more common in other areas of the world.
Most people with early stomach cancer have no signs or symptoms of the condition. In advanced stages, symptoms may include indigestion; nausea and vomiting; difficulty swallowing; feeling full after eating small amounts of food; loss of appetite; vomiting blood; fatigue; and/or weight loss. Most cases of stomach cancer occur sporadically in people with little to no family history of the condition; however, approximately 10% of stomach cancers are considered "familial." Although the underlying cause of some familial cases is unknown, genetic changes (mutations) are identified in a subset of people affected by stomach cancer. Hereditary cancer syndromes associated with a predisposition to stomach cancer include hereditary diffuse gastric cancer, Lynch syndrome, Li-Fraumeni syndrome, familial adenomatous polyposis, and Peutz-Jeghers syndrome. In other families, a cluster of stomach cancers may be due to a combination of gene(s) and/or other shared factors such as environment and lifestyle. The best treatment options for stomach cancer depend on many factors including the stage of the condition and may include surgery, chemotherapy, radiation therapy, and/or targeted therapy (such as monoclonal antibody therapy).
Cancer of the stomach that tends to run in families
A rare disorder where blood platelet defects cause bleeding problems as the platelets are unable to function normally in the blood clotting process
