Most hormonally active tumors of the digestive system are localized in the pancreas. This is due to the abundance of hormonally competent cells in it, from which such tumors originate.

Hormonal disruption in women

Hormonal disruption in women )HGH) is a condition in which the normal functioning of the endocrine system is disrupted, which can lead to various diseases and symptoms.

Hodgkin's lymphoma (lymphogranulomatosis) in children

Hodgkin's lymphoma (Hodgkin's disease, lymphogranulomatosis) is a malignant tumor of lymphoid tissue with a specific granulomatous histological structure. The disease occurs in all age groups, with the exception of children in the first year of life; it is rare at the age of up to 5 years. Among all lymphomas in children, Hodgkin's disease accounts for about 40%.

Hodgkin's lymphoma (Hodgkin's disease): causes, symptoms, diagnosis, treatment

Hodgkin lymphoma (Hodgkin's disease) is a localized or disseminated malignant proliferation of cells of the lymphoreticular system, affecting primarily the tissue of the lymph nodes, spleen, liver, and bone marrow. Symptoms include painless lymphadenopathy, sometimes with fever, night sweats, gradual weight loss, pruritus, splenomegaly, and hepatomegaly. Diagnosis is based on lymph node biopsy.

Hives in children

Urticaria in children is an allergic skin disease characterized by the appearance of rashes on the skin, which may be red, itchy and resemble nettle stings.

HIV infection in pregnant women

Human immunodeficiency virus (HIV) is an anthroponotic infection characterized by progressive damage to the immune system, leading to the development of acquired immunodeficiency syndrome (AIDS) and death from secondary diseases. The pathogen belongs to the family of retroviruses (Retroviridae), subfamily of slow viruses (Lentivirus).

HIV infection and eye disease in children

The fetus is infected through the mother's placenta. The disease manifests itself in 40% of children born to affected women.

HIV infection and eye changes

In patients with acquired immunodeficiency, against the background of other lesions, chorioretinitis is usually detected during generalization of cytomegalovirus infection.

HIV infection and AIDS in children

HIV infection, AIDS - a viral disease of the immune system, leading to a sharp decrease in the body's overall resistance to opportunistic microorganisms, as well as an increased susceptibility to cancer, which is why the disease has a severe course with an inevitable fatal outcome.

HIV infection and AIDS

HIV infection is caused by one of two retroviruses (HIV-1 and HIV-2) that destroy CD4+ lymphocytes and disrupt the cellular immune response, thereby increasing the risk of certain infections and tumors. Initially, infection may manifest itself as a non-specific febrile fever. The likelihood of subsequent manifestations depends on the degree of immunodeficiency and is proportional to the level of CD4+ lymphocytes. Manifestations range from asymptomatic course to acquired immunodeficiency syndrome (AIDS)

HIV dementia

AIDS caused by HIV is characterized by CNS damage, which can also be attributed to slow infectious processes in the CNS. The pathogenesis of CNS damage in neuroAIDS is associated with the direct neurotoxic effect of the virus, as well as with the pathological effect of cytotoxic T cells and anti-brain antibodies.

Histoplasmosis of the eye. Causes. Symptoms. Diagnosis. Treatment

Histoplasmosis of the eye is a disease caused by the fungus Histoplasnia capsulatum, which exists in two forms: in humans - as a yeast, and in contaminated soil - as a mold.

Histiocytosis-X of the skin. Causes. Symptoms. Diagnosis. Treatment

Histiocytosis X of the lung (histiocytic granulomatosis of the lung). Causes. Symptoms. Diagnosis. Treatment

Histiocytosis X of the lungs (histiocytic granulomatosis of the lungs) is a disease of the reticulohistiocytic system of unknown etiology, characterized by the proliferation of histiocytes (X cells) and the formation of histiocytic granulomas in the lungs and other organs and tissues.

Hiss bundle branch blockade: causes, symptoms, diagnosis, treatment

Bundle branch block is a partial or complete disruption of impulse conduction along a bundle branch; bundle branch block is a similar disruption of conduction along the entire bundle branch. Both disorders are often combined.

Hirsutism: causes, treatment

Hirsutism (hypertrichosis) is excessive hair growth with or without virilization. Hirsutism is excessive male-pattern hair growth in women. What causes hirsutism? Treatment for hirsutism

Hirschsprung's disease (congenital megacolon)

Hirschsprung's disease (congenital megacolon) is a congenital anomaly of the innervation of the lower intestine, usually limited to the colon, resulting in partial or complete functional intestinal obstruction. Symptoms include persistent constipation and abdominal distension. Diagnosis is by barium enema and biopsy. Treatment of Hirschsprung's disease is surgical.

Hippel-Lindau disease (Hippel-Lindau): causes, symptoms, diagnosis, treatment

Angiomatosis of the retina and cerebellum constitute a syndrome known as von Hippel-Lindau disease. The disease is inherited in an autosomal dominant manner.

Hip trochanteritis

Trochanteritis of the hip joint is a diagnosis that sounds very frightening to the average patient. A number of questions immediately arise: what it is, how to treat it, which doctor to consult, what to expect, and what is its prognosis.
