Hematology

Hematology, also spelled haematology, is the branch of medicine concerned with the study of the cause, diagnosis, treatment, and prevention of diseases related to blood. It involves treating diseases that affect the production of blood and its components, such as blood cells, hemoglobin, blood proteins, bone marrow, platelets, blood vessels, spleen, and the mechanism of coagulation. Such diseases might include hemophilia, blood clots, other bleeding disorders and blood cancers such as leukemia, multiple myeloma, and lymphoma. The laboratory work that goes into the study of blood is frequently performed by a medical technologist or medical laboratory scientist. Many hematologists work as hematologist-oncologists, also providing medical treatment for all types of cancer. The term is from the Greek αἷμα, haima meaning "blood," and -λoγία meaning study.

Specialization


Physicians specialized in hematology are known as hematologists or haematologists. Their routine work mainly includes the care and treatment of patients with hematological diseases, although some may also work at the hematology laboratory viewing blood films and bone marrow slides under the microscope, interpreting various hematological test results and blood clotting test results. In some institutions, hematologists also manage the hematology laboratory. Physicians who work in hematology laboratories, and most commonly manage them, are pathologists specialized in the diagnosis of hematological diseases, referred to as hematopathologists or haematopathologists. Hematologists and hematopathologists generally work in conjunction to formulate a diagnosis and deliver the most appropriate therapy if needed. Hematology is a distinct subspecialty of internal medicine, separate from but overlapping with the subspecialty of medical oncology. Hematologists may specialize further or have special interests, for example, in:

treating bleeding disorders such as hemophilia and idiopathic thrombocytopenic purpura
treating hematological malignancies such as lymphoma and leukemia (cancers)
treating hemoglobinopathies
the science of blood transfusion and the work of a blood bank
bone marrow and stem cell transplantation

Training

To begin in this career, hematologists complete a four-year medical degree which is followed by three or four more years, depending on the person, in residency or internship programs. After completion, they further expand their knowledge of hematology by spending two or three more years learning how to experiment, diagnose, and treat blood disorders. When applying for this career, most job openings look for first hand practical experiences in a recognized training program that provides practice in the following: Cause of abnormalities in formation of blood and other disorders, diagnosis of numerous blood related conditions or cancers using experimentation, and the proper care and treatment of patients in the best manner.

Platelet

Platelet Platelets, also called thrombocytes (thromb- + -cyte, "blood clot cell"), are a component of blood whose function (along with the coagulation factors) is to stop bleeding by clumping and clotting blood vessel injuries. Platelets have no cell nucleus: they are fragments of cytoplasm that are derived from the megakaryocytes of the bone marrow, and then enter the circulation. These unactivated platelets are biconvex discoid (lens-shaped) structures, 2–3 µm in greatest diameter. Platelets are found only in mammals, whereas in other animals (e.g. birds, amphibians) thrombocytes circulate as intact mononuclear cells. The ligands, denoted by letter L, signal for platelets (P) to migrate towards the wound (Site A). As more platelets gather around the opening, they produce more ligands to amplify the response. The platelets congregate around the wound in order to create a cap to stop blood flow out of the tissue. On a stained blood smear, platelets appear as dark pur...

Explains anxiety and panic attacks, including possible causes and how you can access treatment and support. Includes tips for helping yourself, and guidance for friends and family. About anxiety What is anxiety? Anxiety is what we feel when we are worried, tense or afraid – particularly about things that are about to happen, or which we think could happen in the future. Anxiety is a natural human response when we perceive that we are under threat. It can be experienced through our thoughts, feelings and physical sensations. For me, anxiety feels as if everyone in the world is waiting for me to trip up, so that they can laugh at me. It makes me feel nervous and unsure whether the next step I take is the best way forward. Most people feel anxious at times. It's particularly common to experience some anxiety while coping with stressful events or changes, especially if they could have a big impact on your life.  What is the 'fight, flight or freeze' resp...

Fifth disease

Fifth disease  is a mild rash illness caused by parvovirus B19. It is more common in children than adults. ... This  disease , also called erythema infectiosum, got its name because it was fifth  in a list of historical classifications of common skin rash illnesses in children. Erythema infectiosum or fifth disease is one of several possible manifestations of infection by parvovirus B19. The name "fifth disease" comes from its place on the standard list of rash-causing childhood diseases, which also includes measles (1st), scarlet fever (2nd), rubella (3rd), Dukes' disease (4th, however is no longer widely accepted as distinct) and roseola (6th). Signs and symptoms Fifth disease starts with a low-grade fever, headache, rash, and cold-like symptoms, such as a runny or stuffy nose. These symptoms pass, then a few days later the rash appears. The bright red rash most commonly appears in the face, particularly the cheeks. This is a defining symptom of the infecti...
