Liver (Anatomy and Function)
The liver is the largest gland and organ in the body. There are a variety of liver diseases caused by liver inflammation, scarring of the liver, infection of the liver, gallstones, cancer, toxins, genetic diseases, and blood flow problems. Symptoms of liver disease generally do not occur until the liver disease is advanced. Some symptoms of liver disease include jaundice, nausea and vomiting, easy bruising, bleeding excessively, fatigue, weakness, weight loss, shortness of breath, leg swelling, impotence, and confusion. Treatment of diseases of the liver depends on the cause.
Antiphospholipid syndrome (phospholipid antibody syndrome or Hughes syndrome) is an immune system disorder with symptoms that include: excessive blood clotting, miscarriages unexplained fetal death, or premature birth. In antiphospholipid syndrome, these symptoms are accompanied by the presence of antiphospholipid antibodies (cardiolipin or lupus anticoagulant antibodies) in the blood. Treatment focuses on preventing clotting by thinning the blood with the use of anticoagulants and aspirin.
Fever in Adults and Children
Although a fever technically is any body temperature above the normal of 98.6 F (37 C), in practice, a person is usually not considered to have a significant fever until the temperature is above 100.4 F (38 C). Fever is part of the body's own disease-fighting arsenal; rising body temperatures apparently are capable of killing off many disease-producing organisms.
Influenza (flu) is a respiratory illness caused by a virus. Flu symptoms include fever, cough, sore throat, runny nose, headache, fatigue, and muscle aches. The flu may be prevented with an annual influenza vaccination.
Neutropenia (Causes, Symptoms, Ranges, Treatment)
Neutropenia is a marked decrease in the number of neutrophils, neutrophils being a type of white blood cell (specifically a form of granulocyte) filled with neutrally-staining granules, tiny sacs of enzymes that help the cell to kill and digest microorganisms it has engulfed by phagocytosis. Signs and symptoms of neutropenia include gum pain and swelling, skin abscesses, recurrent ear and sinus infections, sore mouth, low-grad fever, pneumonia-like symptoms, and pain and irritation around the rectal area. Neutropenia has numerous causes, for example, infections (HIV, TB, mono); medications (chemotherapy); vitamin deficiencies (anemia); bone marrow diseases (leukemias), radiation therapy, autoimmune destruction of neutrophils, and hypersplenism. Treatment of neutropenia depends upon the cause and the health of the patient.
Epilepsy is a brain disorder in which the person has seizures. There are two kinds of seizures, focal and generalized. There are many causes of epilepsy. Treatment of epilepsy (seizures) depends upon the cause and type of seizures experienced.
Sickle Cell Disease (Anemia)
Sickle cell anemia (sickle cell disease), a blood disease which shortens life expectancy, is caused by an inherited abnormal hemoglobin. Symptoms of sickle cell anemia may include bacterial infections, painful swelling of the hands and feet, fever, leg ulcers, fatigue, anemia, eye damage, and lung and heart injury. Treatment for sickle cell anemia aims to manage and prevent the worst manifestations of the disease and focuses on therapies that block red blood cells from stacking together, which can lead to tissue and organ damage and pain.
Beta Thalassemia is the most familiar type of thalassemia. Thalassemia is not just one disease but rather a complex series of genetic (inherited) disorders all of which involve underproduction of hemoglobin. Beta thalassemia major symptoms include pale skin, irritability, growth retardation, swelling of the abdomen, and jaundice. Beta thalassemia treatments include directly relieving the symptoms of the illness.
Travelers should prepare for their trip by visiting their physician to get the proper vaccinations and obtain the necessary medication if they have a medical condition or chronic disease. Diseases that travelers may pick up from contaminated water or food, insect or animal bites, or from other people include: malaria, meningococcal meningitis, yellow fever, hepatitis A, typhoid fever, polio, and cholera.
Jaundice (Hyperbilirubinemia) in Adults
Jaundice (hyperbilirubinemia) in adults may be caused by a variety of medical diseases or conditions. Some cases of jaundice can be managed at home with a doctor's supervision, while other causes of jaundice may be life-threatening. Symptoms of jaundice are yellow skin, yellowing of the whites of the eyes, pale colored stools, dark urine, itchy skin, vomiting, nausea, and rectal bleeding. Treatment of jaundice is focused on the disease or condition that is causing jaundice.
Diarrhea is a change is the frequency and looseness of bowel movements. Symptoms associated with diarrhea are cramping, abdominal pain, and the sensation of rectal urgency. Causes of diarrhea include viral, bacterial, or parasite infection, gastroenteritis, food poisoning, and drugs. Absorbents and anti-motility medications are used to treat diarrhea.
Chronic cough is a cough that does not go away and is generally a symptom of another disorder such as asthma, allergic rhinitis, sinus infection, cigarette smoking, GERD, postnasal drip, bronchitis, pneumonia, medications, and less frequently tumors or other lung disease. Chronic cough treatment is based on the cause, but may be soothed natural and home remedies.
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased. There are several types of anemia such as iron deficiency anemia (the most common type), sickle cell anemia, vitamin B12 anemia, pernicious anemia, and aplastic anemia. Symptoms of anemia may include fatigue, malaise, hair loss, palpitations, menstruation, and medications. Treatment for anemia includes treating the underlying cause for the condition. Iron supplements, vitamin B12 injections, and certain medications may also be necessary.
G6PD deficiency (Glucose 6-phosphate dehydrogenase) leads to a condition called hemolytic anemia. Causes of G6PD deficiency is an abnormal gene located in the X-chromosome, therefore, it is more common in males. Hemolytic anemia caused by G6PD deficiency generally occurs after exposure to malaria medications, antiitching drugs, and fava beans. Pneumonia and other infections can also precipitate hemolytic anemia in individuals with G6PD deficiency. Treatment is generally discontinuing the drug or compound treating infection. Blood transfusions are necessary in some individuals.
Alpha thalassemia is a disorder in which the alpha globin protein is underproduced. There are two pairs of genes that carry the code for the alpha chains of hemoglobin. When one gene is impaired, that person is in a carrier state and suffers no medical problems. When four genes are impaired, the production of fetal and adult hemoglobin is prevented, resulting in hydrops fetalis and leading to death before birth.
Kidney (Renal) Failure
Kidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, or medication. Some of the renal causes of kidney failure include sepsis, medications, rhabdomyolysis, multiple myeloma, and acute glomerulonephritis. Post renal causes of kidney failure include bladder obstruction, prostate problems, tumors, or kidney stones.Treatment options included diet, medications, or dialysis.
Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
Children's health is focused on the well-being of children from conception through adolescence. There are many aspects of children's health, including growth and development, illnesses, injuries, behavior, mental illness, family health, and community health.
Antibiotic Resistance (Drug Resistance, Antimicrobial Resistance)
Antibiotics are medications used to kill or slow the growth of bacteria and some fungi. The definition of antibiotic resistance is the ability of bacteria to change (mutate) and grow in the presence of a drug (an antibiotic) that would normally slow its growth or kill it. These antibiotic-resistant bacteria and fungi become harder to treat. Antibiotic-resistant infections can lead to longer hospital stays, higher treatment costs, and more deaths.
Nausea and Vomiting (Causes, Natural Remedies, Diet, Medication)
Nausea is an uneasiness of the stomach that often precedes vomiting. Nausea and vomiting are not diseases, but they are symptoms of many conditions. There are numerous cases of nausea and vomiting. Some causes may not require medical treatment, for example, motion sickness, and other causes may require medical treatment by a doctor, for example, heart attack, lung infections, bronchitis, and pneumonia. Some causes of nausea and vomiting may be life threatening, for example, heart attack, abdominal obstruction, and cancers. Treatment of nausea and vomiting depends upon the cause.
Seizures Symptoms and Types
Seizures are divided into two categories: generalized and partial. Generalized seizures are produced by electrical impulses from throughout the brain, while partial seizures are produced by electrical impulses in a small part of the brain. Seizure symptoms include unconsciousness, convulsions, and muscle rigidity.
Medical shock is a life-threatening medical condition. There are several types of medical shock, including: septic shock, anaphylactic shock, cardiogenic shock, hypovolemic shock, and neurogenic shock. Causes of shock include: heart attack, heart failure, heavy bleeding (internal and external), infection, anaphylaxis, spinal cord injury, severe burns, chronic vomiting or diarrhea. Low blood pressure is the key sign of sock. Treatment is dependant upon the type of shock.
Enlarged Spleen (Splenomegaly) Symptoms, Signs, Causes,Treatment
An enlarged spleen or splenomegaly, is generally caused by other diseases or conditions such as infections, cancers, blood disorders, or decreased blood flow. Symptoms of an enlarged spleen are often unnoticed. A feeling of fullness after eating a small amount of food and not being able to eat large meals may be a symptom of an enlarged spleen. Treatment for an enlarged spleen depends upon the cause.
Fatigue can be described in various ways. Sometimes fatigue is described as feeling a lack of energy and motivation (both mental and physical). The causes of fatigue are generally related to a variety of conditions or diseases, for example, anemia, mono, medications, sleep problems, cancer, anxiety, heart disease, and drug abuse.Treatment of fatigue is generally directed toward the condition or disease that is causing the fatigue.
Is Malaria Contagious?
Malaria is transmitted via the bite of an infected mosquito. The incubation period for malaria depends upon the species of Plasmodium that the infected mosquito transmits to the individual. Symptoms include high fever, chills, sweating, headaches, vomiting, and nausea.
Burkitt lymphomas are types of non-Hodgkin's lymphoma that affect the bone marrow and central nervous system. There are multiple types of Burkitt lymphoma. Gene mutations, malaria, and Epstein-Barr virus (EBV) may increase the risk of these cancers. Symptoms of Burkitt lymphoma may include nausea, vomiting, headache, fatigue, enlarged lymph nodes, and many other symptoms. Diagnosis involves lab testing, imaging studies, patient history, and cytogenic evaluation. There are multiple staging systems used to stage Burkitt lymphoma. Treatment consists of chemotherapy. The prognosis of the cancer tends to be more favorable in children than in adults.
