• PEPCK 2 deficiency: A rare inherited disorder where deficiency of an enzyme (phosphoenolpyruvate carboxykinase-2) prevents fats and proteins being turned into glucose which causes various problems. In type 2 the deficiency occurs in the mitochondrial part of the cell which is the energy conversion organelle in the cell.
• Pancreatic adenoma: A pancreatic tumor which may be benign or malignant. Symptoms may vary depending on the location and size of the tumor as well as whether the tumor secretes hormones or not. For example, the tumor may block the biliary duct.
• Pancreatic cancer, adult: Cancer that develops in the tissues of the pancreas. The pancreas produces digestive juices and certain hormones such as insulin that regulate sugar levels in the body and tumors can in some cases causes excessive hormone secretion.
• Pancreatic islet cell tumors (functioning tumor): A tumor that arises from the pancreatic islet cells and produces too many hormones.
• Pancreatic islet cell tumors (non-functioning tumor): A tumor that arises from the pancreatic islet cells and may involve cells that produce excess pancreatic hormones.
• Phosphoenolpyruvate carboxykinase (PEPCK) deficiency: A rare inherited disorder where deficiency of an enzyme (phosphoenolpyruvate carboxykinase-1) prevents fats and proteins being turned into glucose which causes various problems. In type 1, the enzyme deficiency occurs in the liquid part of the cells and in type 2 the deficiency occurs in the mitochondrial part of the cell.
• Pituitary dwarfism 1: A rare form of dwarfism caused by a lack of growth hormones. Patients have normal body proportions and sexual development was normal.
• Pregnancy: Symptoms related to pregnancy.
• Pregnancy symptoms: Symptoms related to pregnancy.
• Probable human carcinogen - Chloramphenicol: Chloramphenicol (an antibiotic) is deemed to be a probable carcinogen to humans. The carcinogenicity of the substance may be influenced by the duration and level of exposure.
• Pyridoxamine 5-prime-phosphate oxidase deficiency: A metabolic disorder involving a deficiency of an enzyme called 5-prime-phosphate oxidase. Symptoms start soon after birth and involves seizures and other anomalies.
• Quinine - Teratogenic Agent: There is evidence to indicate that exposure to Quinine during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
• Reye's syndrome: is a potentially fatal disease that causes numerous detrimental effects to many organs, especially the brain and liver
• Rimbaud-Passouant-Vallat syndrome: A type of brain inflammation.
• SCHAD Deficiency - formerly: A rare inherited form of biochemical disorder characterized by the deficiency of a particular enzyme (3-Hydroxyacyl-CoA Dehydrogenase). The enzyme deficiency only affects certain body tissues, in particular the skeletal muscles. The lack of enzyme activity prevents some fats being converted into energy. Symptoms tend to be exacerbated during fasting as during fasting, the body tries to rely more heavily on fats for energy. Fatty acids that are not completely metabolized due to the enzyme deficiency may build up in various organs and cause serious complications.
• Sheehan Syndrome: A rare condition that occurs in women who suffer a severe uterine hemorrhage during childbirth. The resulting blood loss may damage the pituitary gland and result in hypopituitarism.
• Short Chain Acyl CoA Dehydrogenase Deficiency (SCAD): A rare disorder where the body lacks enzymes needed to convert some fats (short-chain fatty acids) into energy. Symptoms are exacerbated by fasting or acute illness. The severity of symptoms is variable with some patients remaining virtually asymptomatic their whole life while other suffer symptoms from infancy.
• Short stature - pituitary and cerebellar defects - small sella turcica: A rare syndrome characterized mainly by short stature and brain and pituitary gland defects.
• Short-Chain Acyl-CoA Dehydrogenase Deficiency: A rare disorder where the body lacks enzymes needed to convert some fats (short-chain fatty acids) into energy.
• Systemic monochloroacetate poisoning: Monochloracetate acid is a dangerous chemical which can cause systemic poisoning even if only skin exposure occurs. Exposure to the chemical can be life-threatening with serious symptoms starting within hours of the exposure.
• Timme syndrome: A syndrome involving insufficiency of the thymus, adrenal and pituitary glands. The disorder has involves three phases, each of which has varying symptoms: phase 1 is before puberty, phase 2 occurs after puberty and phase 3 tends to occur in the third decade.
• Tolazamide - Teratogenic Agent: There is evidence to indicate that exposure to Tolazamide during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
• Tolbutamide - Teratogenic Agent: There is evidence to indicate that exposure to Tolbutamide during pregnancy may have a teratogenic effect on the fetus. A teratogen is a substance that can cause birth defects. The likelihood and severity of defects may be affected by the level of exposure and the stage of pregnancy that the exposure occurred at.
• Tyrosinemia: A rare genetic metabolic disorder characterized by a deficiency of particular enzymes which prevents the breakdown of tyrosine which then builds up in the liver.
• Visceral leishmaniasis: A tropical disease caused by a protozoan organism and transmitted to humans through sand fly bites. Also called Assam fever, black fever, dumdum fever, ponos or kala-azar.
• Von Gierke Disease: An inherited metabolic disorder where a deficiency of the enzyme glucose-6-phosphatase prevents glycogen being turned into glucose leading to a buildup of glycogen in the liver and kidneys.
• Von Gierke disease IA: A genetic metabolic disorder involving a deficiency of the enzyme glucose-6-phosphatase which results in the accumulation of glycogen in various tissues. G6P is stored as glycogen until the body needs to convert it to a sugar and use it to create energy. The enzyme deficiency prevents the conversion and hence low blood sugar levels result.
• Von Gierke disease IB: A metabolic disorder involving a deficiency of glucose-6-phosphatase (due to a G6P transporter defect) which results in the accumulation of glycogen in various tissues and a reduced blood sugar level. The condition is characterized primarily by an increased risk of bacterial infections due to impaired neutrophil activity which is needed to fight bacterial invasions.
• Wiedemann-Beckwith syndrome: A rare genetic disorder characterized by an enlarged tongue, omphalocele, excessive birth weight and ear creases.
