Label	Id	Description
Horse Diseases	D006734	[Diseases of domestic and wild horses of the species Equus caballus.]
Hot Flashes	D019584	[A sudden, temporary sensation of heat predominantly experienced by some women during MENOPAUSE. (Random House Unabridged Dictionary, 2d ed)]
Humeral Fractures	D006810	[Fractures of the HUMERUS.]
Huntington Disease	D006816	[A familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive CHOREA and DEMENTIA in the fourth or fifth decade of life. Common initial manifestations include paranoia; poor impulse control; DEPRESSION; HALLUCINATIONS; and DELUSIONS. Eventually intellectual impairment; loss of fine motor control; ATHETOSIS; and diffuse chorea involving axial and limb musculature develops, leading to a vegetative state within 10-15 years of disease onset. The juvenile variant has a more fulminant course including SEIZURES; ATAXIA; dementia; and chorea. (From Adams et al., Principles of Neurology, 6th ed, pp1060-4)]
Hutchinson's Melanotic Freckle	D018327	[A cellular subtype of malignant melanoma. It is a pigmented lesion composed of melanocytes occurring on sun-exposed skin, usually the face and neck. The melanocytes are commonly multinucleated with a "starburst" appearance. It is considered by many to be the in situ phase of lentigo maligna melanoma.]
Hyaline Membrane Disease	D006819	[A respiratory distress syndrome in newborn infants, usually premature infants with insufficient PULMONARY SURFACTANTS. The disease is characterized by the formation of a HYALINE-like membrane lining the terminal respiratory airspaces (PULMONARY ALVEOLI) and subsequent collapse of the lung (PULMONARY ATELECTASIS).]
Hyalinosis, Systemic	D057770	[Autosomal recessive disorder characterized by HYALINE deposition in the skin, bone, gastrointestinal tract, muscles and glands; multiple subcutaneous skin nodules; GINGIVAL HYPERTROPHY; and joint CONTRACTURES. Mutations in the capillary morphogenesis protein-2 are associated with the disorder.]
Hyalohyphomycosis	D060605	[OPPORTUNISTIC INFECTIONS caused by a heterogeneous group of MITOSPORIC FUNGI with clear (hyalo-) HYPHAE in the host. Common causative agents include ACREMONIUM; ASPERGILLUS; CHRYSOSPORIUM; FUSARIUM; PAECILOMYCES; PENICILLIUM; PSEUDALLESCHERIA; SCEDOSPORIUM; and SCOPULARIOPSIS. Normally a dermatomycoses, it can become invasive in the IMMUNOCOMPROMISED HOST.]
Hydatidiform Mole	D006828	[Derived from the fertilization of an apparently normal ovum by two sperm. Partial hydatidiform moles are characterized by focal chorionic villi swelling, focal trophoblastic hyperplasia, and identifiable fetal or embryonic tissue. Partial moles generally have a triploid karyotype., Derived from the fertilization of an anuclear ovum by one or sometimes two haploid sperm. Its molar chromosomes derive entirely from the paternal origin. It has no identifiable embryonic or fetal tissue. The chorionic villi have generalized swelling and diffuse trophoblastic hyperplasia. Most complete moles (>90%) have a 46,XX karyotype and the rest 46,XY karyotype., Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. It is characterized by the swelling of the CHORIONIC VILLI and elevated human CHORIONIC GONADOTROPIN. Hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.]
Hydatidiform Mole, Invasive	D002820	[A uterine tumor derived from persistent gestational TROPHOBLASTS, most likely after a molar pregnancy (HYDATIDIFORM MOLE). Invasive hyadatiform mole develops in about 15% of patients after evacuation of a complete mole and less frequently after other types of gestation. It may perforate the MYOMETRIUM and erode uterine vessels causing hemorrhage.]
Hydranencephaly	D006832	[A congenital condition where the greater portions of the cerebral hemispheres and CORPUS STRIATUM are replaced by CSF and glial tissue. The meninges and the skull are well formed, which is consistent with earlier normal embryogenesis of the telencephalon. Bilateral occlusions of the internal carotid arteries in utero is a potential mechanism. Clinical features include intact brainstem reflexes without evidence of higher cortical activity. (Menkes, Textbook of Child Neurology, 5th ed, p307)]
Hydrarthrosis	D006833	[Accumulation of watery fluid in the cavity of a joint. (Dorland, 27th ed)]
Hydroa Vacciniforme	D006837	[A vesicular and bullous eruption having a tendency to recur in summer during childhood and commonly appearing on sun-exposed skin. The lesions are surrounded by an erythematous zone and resemble a vaccination. (From Dorland, 27th ed)]
Hydrocephalus	D006849	[Excessive accumulation of cerebrospinal fluid within the cranium which may be associated with dilation of cerebral ventricles, INTRACRANIAL HYPERTENSION; HEADACHE; lethargy; URINARY INCONTINENCE; and ATAXIA., Enlargement of CEREBRAL VENTRICLES. Although it is often isolated without other CNS anomalies it can be associated with other congenital malformations (e.g., ARNOLD-CHIARI MALFORMATION; DANDY-WALKER MALFORMATION, and ACROCALLOSAL SYNDROME).]
Hydrocephalus, Normal Pressure	D006850	[A form of compensated hydrocephalus characterized clinically by a slowly progressive gait disorder (see GAIT DISORDERS, NEUROLOGIC), progressive intellectual decline, and URINARY INCONTINENCE. Spinal fluid pressure tends to be in the high normal range. This condition may result from processes which interfere with the absorption of CSF including SUBARACHNOID HEMORRHAGE, chronic MENINGITIS, and other conditions. (From Adams et al., Principles of Neurology, 6th ed, pp631-3)]
Hydrocolpos	D052202	[A fluid-filled VAGINA that is obstructed.]
Hydronephrosis	D006869	[Abnormal enlargement or swelling of a KIDNEY due to dilation of the KIDNEY CALICES and the KIDNEY PELVIS. It is often associated with obstruction of the URETER or chronic kidney diseases that prevents normal drainage of urine into the URINARY BLADDER.]
Hydrophthalmos	D006871	[Congenital open-angle glaucoma that results from dysgenesis of the angle structures accompanied by increased intraocular pressure and enlargement of the eye. Treatment is both medical and surgical.]
Hydropneumothorax	D006872	[A collection of fluid and gas within the pleural cavity. (Dorland, 27th ed)]
Hydrops Fetalis	D015160	[Abnormal accumulation of serous fluid in two or more fetal compartments, such as SKIN; PLEURA; PERICARDIUM; PLACENTA; PERITONEUM; AMNIOTIC FLUID. General fetal EDEMA may be of non-immunologic origin, or of immunologic origin as in the case of ERYTHROBLASTOSIS FETALIS.]
