Preeclampsia Pre-eclampsia is gestational hypertension plus proteinuria (>300 mg of protein in a 24-hour urine sample). Severe preeclampsia involves a blood pressure greater than 160/110, with additional medical signs and symptoms. HELLP syndrome is a type of preeclampsia. It is a combination of three medical conditions: hemolytic anemia, elevated liver enzymes and low ...
... is a rare life-threatening complication of pregnancy that occurs in the third trimester or the immediate period after delivery. It is thought to be caused by a disordered metabolism of fatty acids by mitochondria in the mother, caused by long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency. The condition was previously thought to be universally fatal, but aggressive treatment by stabilizing the mother with intravenous fluids and blood products in anticipation of early delivery has improved prognosis. Acute fatty liver of pregnancy (or hepatic lipidosis of pregnancy) usually manifests in the third trimester of pregnancy, but may occur any time in the second half of pregnancy, or in the puerperium, the period immediately after delivery. On average, the disease presents during the 35th or 36th week of pregnancy. The usual symptoms in the mother are non-specific including nausea, vomiting, anorexia (or lack of desire to eat) and abdominal pain; excessive thirst ...
... , sold under the brand name Fareston among others, is a medication which is used in the treatment of advanced breast cancer in postmenopausal women. It is taken by mouth. Side effects of toremifene include hot flashes, sweating, nausea, vomiting, dizziness, vaginal discharge, and vaginal bleeding. It can also cause blood clots, irregular heartbeat, cataracts, visual disturbances, elevated liver enzymes, endometrial hyperplasia, and endometrial cancer. High blood calcium levels can occur in women with bone metastases. The drug is a selective estrogen receptor modulator (SERM) and hence is a mixed agonist-antagonist of the estrogen receptor (ER), the biological target of estrogens like estradiol. It has estrogenic effects in bone, the liver, and the uterus and antiestrogenic effects in the breasts. It is a triphenylethylene derivative and is closely related to tamoxifen. Toremifene was introduced for medical use in 1997. It was the first antiestrogen to be introduced since tamoxifen in ...
... (abbreviated as CPA), sold alone under the brand name Androcur or with ethinylestradiol (EE) under the brand names Diane or Diane-35 among others, is an antiandrogen and progestogen which is used in the treatment of androgen-dependent conditions like acne, excessive hair growth, early puberty, and prostate cancer, as a component of feminizing hormone therapy for transgender women, and in birth control pills. It is formulated and used both alone and in combination with an estrogen and is available for use both by mouth and by injection into muscle. Common side effects of non-contraceptive (i.e., high) dosages of CPA in men include gynecomastia (breast development) and feminization in general and in both men and women include low sex hormone levels, reversible infertility, sexual dysfunction, mental symptoms like depression, fatigue, and irritability, vitamin B12 deficiency, and elevated liver enzymes. At very high dosages, cardiovascular side effects can occur. Rare but ...
As of September 2018, two CGRP blockers have been approved by the FDA for the treatment of migraine.[21] Additional CGRP blockers are progressing through clinical trials.[22] Anticipating later botox therapy for migraine, early work by Jancsó et al. found some success in treatment using denervation or pretreatment with capsaicin to prevent uncomfortable symptoms of neurogenic inflammation.[23] A recent (2010) study of the treatment of migraine with CGRP blockers shows promise.[24] In early trials, the first oral nonpeptide CGRP antagonist, MK-0974 (Telcagepant), was shown effective in the treatment of migraine attacks,[25] but elevated liver enzymes in two participants were found. Other therapies and other links in the neurogenic inflammatory pathway for interruption of disease are under study, including migraine therapies.[26] Noting that botulinum toxin has been shown to have an effect on inhibiting neurogenic inflammation, and evidence suggesting the role of neurogenic inflammation in the ...
... (more accurately called thrombocytapheresis or thrombapheresis, though these names are rarely used) is the process of collecting thrombocytes, more commonly called platelets, a component of blood involved in blood clotting. The term specifically refers to the method of collecting the platelets, which is performed by a device used in blood donation that separates the platelets and returns other portions of the blood to the donor. Platelet transfusion can be a life-saving procedure in preventing or treating serious complications from bleeding and hemorrhage in patients who have disorders manifesting as thrombocytopenia (low platelet count) or platelet dysfunction. This process may also be used therapeutically to treat disorders resulting in extraordinarily high ...
... (MPV) is a machine-calculated measurement of the average size of platelets found in blood and is typically included in blood tests as part of the CBC. Since the average platelet size is larger when the body is producing increased numbers of platelets, the MPV test results can be used to make inferences about platelet production in bone marrow or platelet destruction problems. MPV is higher when there is destruction of platelets. This may be seen in inflammatory bowel disease, immune thrombocytopenic purpura (ITP), myeloproliferative diseases and Bernard-Soulier syndrome. It may also be related to pre-eclampsia, and recovery from, transient hypoplasia. Abnormally low MPV values correlate with thrombocytopenia when it is due to impaired production as in aplastic anemia. ...
A review in people with blood cancers receiving intensive chemotherapy or a stem cell transplant found that overall giving platelet transfusions when the platelet count is less than 10 x 109/L reduced the number of bleeding events and days with significant bleeding.[15] However, this benefit was only seen in certain patient groups, and people undergoing an autologous stem cell transplant derived no obvious benefit.[15] Despite prophylactic platelet transfusions, people with blood cancers often bleed, and other risk factors for bleeding such as inflammation and duration of thrombocytopenia should be considered.[13]. There is little evidence for the use of preventative platelet transfusions in people with chronic bone marrow failure, such as myelodysplasia or aplastic anemia.[16] Multiple guidelines recommend prophylactic ...
... are purpura associated with a reduction in circulating blood platelets which can result from a variety of causes, such as kaposi sarcoma. By tradition, the term idiopathic thrombocytopenic purpura is used when the cause is idiopathic. However, most cases are now considered to be immune-mediated. Another form is thrombotic thrombocytopenic purpura. Diagnosis is done by the help of symptoms and only blood count abnormality is thrombocytopenia. Thrombocyte Hematopoietic ulcer Aspirin "thrombocytopenic purpura" at Dorland's Medical ...
... (HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant. HIT predisposes to thrombosis (the abnormal formation of blood clots inside a blood vessel) because platelets release microparticles that activate thrombin, thereby leading to thrombosis. When thrombosis is identified the condition is called heparin-induced thrombocytopenia and thrombosis (HITT). HIT is caused by the formation of abnormal antibodies that activate platelets. If someone receiving heparin develops new or worsening thrombosis, or if the platelet count falls, HIT can be confirmed with specific blood tests. The treatment of HIT requires stopping heparin treatment, and both protection from thrombosis and choice of an agent that will not reduce the ...

... (trade names Jakafi /ˈdʒækəfaɪ/ JAK-ə-fye and Jakavi) is a drug for the treatment of intermediate or high-risk myelofibrosis, a type of myeloproliferative disorder that affects the bone marrow, and for polycythemia vera (PCV) when there has been an inadequate response to or intolerance of hydroxyurea. Ruxolitinib is a janus kinase inhibitor with selectivity for subtypes JAK1 and JAK2 of this enzyme. Ruxolitinib inhibits dysregulated JAK signaling associated with myelofibrosis. JAK1 and JAK2 recruit signal transducers and activators of transcription (STATs) to cytokine receptors leading to modulation of gene expression. Side effects include pancytopenia,[citation needed] thrombocytopenia (low blood platelet count), anemia (low red blood cell count) and neutropenia; risk of infection; symptom exacerbation if the medication is interrupted or discontinued; and non-melanoma skin cancer. Immunologic side ...
A complete blood count (CBC), also known as a complete blood cell count, full blood count (FBC), or full blood exam (FBE), is a blood panel requested by a doctor or other medical professional that gives information about the cells in a patient's blood, such as the cell count for each cell type and the concentrations of various proteins and minerals. A scientist or lab technician performs the requested testing and provides the requesting medical professional with the results of the CBC. Blood counts of various types have been used for clinical purposes since the 19th century. Automated equipment to carry out complete blood counts was developed in the 1950s and 1960s. The cells that circulate in the bloodstream are generally divided into three types: white blood cells (leukocytes), red blood cells (erythrocytes), and platelets (thrombocytes). ...
