  1. Human Parvovirus B19 infection
    Human Parvovirus B19, a species of parvovirus that infects humans, is linked with the development of several different autoimmune diseases including dematomyositis, mixed connective tissue diseases, a lupus-like illness, a serologically negative (negative RA factor test) form of arthritis, granuloma annulare, autoimmune thyroid disease, autoimmune schizophrenia, and various forms of vasculitis, including Henoch Schonlein purpura, Kawasaki disease, Wegener's granulomatosis, and polyarteritis nodosa. The development of autoimmune conditions following Human Parvovirus B19 arises in people of all ages and occurs more frequently in females. Autoimmune disease development is also known to appear in adults exposed to children with fifth disease [read more]

  2. Human T Cell lymphotropic Virus (HTLV)
    HTLV causes T-cell leukaemia and T-cell lymphoma in adults and may also be engaged in certain demyelinating diseases that includes tropical spastic paraparesis. HTLV is described as a human, single-stranded RNA retrovirus. [read more]

In the absence of this enzyme, a buildup of heparan sulfate and dermatan sulfate occurs in the body. Symptoms appear during childhood and early death can take place due to organ damage. [read more]

  9. Hurthle cell Cancer
    Hurthle cell cancer (or HCC) is a relatively rare and extremely aggressive type of cancer that occurs in the thyroid gland, the gland responsible for secreting hormones that are essential in regulating the metabolism. [read more]

    Medically known as Echinococcosis and other terms are hydatid cyst, unilocular hydatid disease or cystic echinococcosis which is a potentially deadly parasitic disease that can affect numerous animals. [read more]

  13. Hydatidiform mole
    A hydatidiform mole (or hydatid mole, mola hytadidosa) is an anomalous growth containing a nonviable embryo which implants and proliferates within the uterus. [read more]

  14. Hydatidosis
    Echinococcosis, also called hydatid disease, hydatid cyst, unilocular hydatid disease or cystic echinococcosis, is a potentially fatal parasitic disease that can affect many animals, including wildlife, commercial livestock and humans. [read more]

  15. Hydranencephaly
    Hydranencephaly is a rare condition in which the brain's cerebral hemispheres are missing and replaced by sacs filled with cerebrospinal fluid. [read more]

  16. Hydrocele
    A hydrocele is a fluid-filled sac surrounding a testicle that leads to swelling of the scrotum, the loose bag of skin underneath the penis. [read more]

  17. Hydrocephalus
    Hydrocephalus is a term derived from the Greek words "hydro" meaning water, and "cephalus" meaning head, and this condition is sometimes known as "water in the brain". People with this condition have abnormal collection of cerebrospinal fluid (CSF) in the ventricles, or cavities, of the brain. [read more]

  18. Hydrocephalus In Children
    Hydrocephalus is a serious increase of cerebrospinal fluid inside the ventricles of the brain. This is a common dreaded disease among infants that can lead to brain damage. [read more]

  19. Hydronephrosis
    Hydronephrosis is swelling (dilation) of the urine-collecting structures of one or both kidneys because of the obstruction of urine flow from the kidney. This can hinder kidney function. Hydronephrosis is not a specific disease, but a sign of an underlying problem. [read more]

  20. Hydrophobia
