Label	Id	Description
Hypersensitivity, Immediate	D006969	[Hypersensitivity reactions which occur within minutes of exposure to challenging antigen due to the release of histamine which follows the antigen-antibody reaction and causes smooth muscle contraction and increased vascular permeability.]
Glanders	D005896	[A contagious disease of horses that can be transmitted to humans. It is caused by BURKHOLDERIA MALLEI and characterized by ulceration of the respiratory mucosa and an eruption of nodules on the skin.]
Conjunctivitis, Inclusion	D003235	[An infection of the eyes characterized by the presence in conjunctival epithelial cells of inclusion bodies indistinguishable from those of trachoma. It is acquired by infants during birth and by adults from swimming pools. The etiological agent is CHLAMYDIA TRACHOMATIS whose natural habitat appears to be the genito-urinary tract. Inclusion conjunctivitis is a less severe disease than trachoma and usually clears up spontaneously.]
Retropneumoperitoneum	D012188	[Pathological or accidental introduction of air into the retroperitoneal space.]
Ectoparasitic Infestations	D004478	[Infestations by PARASITES which live on, or burrow into, the surface of their host's EPIDERMIS. Most ectoparasites are ARTHROPODS.]
Retroperitoneal Fibrosis	D012185	[A slowly progressive condition of unknown etiology, characterized by deposition of fibrous tissue in the retroperitoneal space compressing the ureters, great vessels, bile duct, and other structures. When associated with abdominal aortic aneurysm, it may be called chronic periaortitis or inflammatory perianeurysmal fibrosis.]
Retroperitoneal Neoplasms	D012186	[New abnormal growth of tissue in the RETROPERITONEAL SPACE.]
Medically Unexplained Symptoms	D000071896	[Persistent health symptoms which remain unexplained after a complete medical evaluation. A cluster of symptoms that consistently appear together but without a known cause are referred to as a MEDICALLY UNEXPLAINED SYNDROME (MUS).]
Retrograde Degeneration	D012183	[Pathologic changes that occur in the axon and cell body of a neuron proximal to an axonal lesion. The process is characterized by central chromatolysis which features flattening and displacement of the nucleus, loss of Nissl bodies, and cellular edema. Central chromatolysis primarily occurs in lower motor neurons.]
Candidemia	D058387	[A form of invasive candidiasis where species of CANDIDA are present in the blood.]
Fungemia	D016469	[The presence of fungi circulating in the blood. Opportunistic fungal sepsis is seen most often in immunosuppressed patients with severe neutropenia or in postoperative patients with intravenous catheters and usually follows prolonged antibiotic therapy.]
Candidiasis, Invasive	D058365	[An important nosocomial fungal infection with species of the genus CANDIDA, most frequently CANDIDA ALBICANS. Invasive candidiasis occurs when candidiasis goes beyond a superficial infection and manifests as CANDIDEMIA, deep tissue infection, or disseminated disease with deep organ involvement.]
Retroviridae Infections	D012192	[Virus diseases caused by the RETROVIRIDAE.]
Squamous Cell Carcinoma of Head and Neck	D000077195	[The most common type of head and neck carcinoma that originates from cells on the surface of the NASAL CAVITY; MOUTH; PARANASAL SINUSES, SALIVARY GLANDS, and LARYNX. Mutations in TNFRSF10B, PTEN, and ING1 genes are associated with this cancer.]
Arthritis, Gouty	D015210	[Arthritis, especially of the great toe, as a result of gout. Acute gouty arthritis often is precipitated by trauma, infection, surgery, etc. The initial attacks are usually monoarticular but later attacks are often polyarticular. Acute and chronic gouty arthritis are associated with accumulation of MONOSODIUM URATE in and around affected joints.]
Gout	D006073	[Metabolic disorder characterized by recurrent acute arthritis, hyperuricemia and deposition of sodium urate in and around the joints, sometimes with formation of URIC ACID calculi.]
Zellweger Syndrome	D015211	[An autosomal recessive disorder due to defects in PEROXISOME biogenesis which involves more than 13 genes encoding peroxin proteins of the peroxisomal membrane and matrix. Zellweger syndrome is typically seen in the neonatal period with features such as dysmorphic skull; MUSCLE HYPOTONIA; SENSORINEURAL HEARING LOSS; visual compromise; SEIZURES; progressive degeneration of the KIDNEYS and the LIVER. Zellweger-like syndrome refers to phenotypes resembling the neonatal Zellweger syndrome but seen in children or adults with apparently intact peroxisome biogenesis.]
Adenovirus Infections, Human	D000258	[Respiratory and conjunctival infections caused by 33 identified serotypes of human adenoviruses.]
Choroid Plexus Neoplasms	D016545	[Benign or malignant tumors which arise from the choroid plexus of the ventricles of the brain. Papillomas (see PAPILLOMA, CHOROID PLEXUS) and carcinomas are the most common histologic subtypes, and tend to seed throughout the ventricular and subarachnoid spaces. Clinical features include headaches, ataxia and alterations of consciousness, primarily resulting from associated HYDROCEPHALUS. (From Devita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2072; J Neurosurg 1998 Mar;88(3):521-8)]
Cerebral Ventricle Neoplasms	D002551	[Neoplasms located in the brain ventricles, including the two lateral, the third, and the fourth ventricle. Ventricular tumors may be primary (e.g., CHOROID PLEXUS NEOPLASMS and GLIOMA, SUBEPENDYMAL), metastasize from distant organs, or occur as extensions of locally invasive tumors from adjacent brain structures.]
