Blood Dyscrasia
In medicine, both ancient and modern, a dyscrasia is any of various disorders. The word has ancient Greek roots meaning "bad mixture". The concept of dyscrasia was developed by the Greek physician Galen (129–216 AD), who elaborated a model of health and disease as a structure of elements, qualities, humors, organs, and temperaments (based on earlier humorism). Health was understood in this perspective to be a condition of harmony or balance among these basic components, called eucrasia. Disease was interpreted as the disproportion of bodily fluids or four humours: phlegm, blood, yellow bile, and black bile. The imbalance was called dyscrasia. In modern medicine, the term is still occasionally used in medical context for an unspecified disorder of the blood, such as a plasma cell dyscrasia. Ancient use To the Greeks, it meant an imbalance of the four humors: blood, black bile, yellow bile, and water (phlegm). These humors were believed to exist in the body, and any change in ...

Medicine
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ayurvedic
Ayurveda () is an alternative medicine system with historical roots in the Indian subcontinent. The theory and practice of Ayurveda is pseudoscientific. Ayurveda is heavily practiced in India and Nepal, where around 80% of the population report using it. Ayurveda therapies have varied and evolved over more than two millennia. Therapies include herbal medicines, special diets, meditation, yoga, massage, laxatives, enemas, and medical oils. Ayurvedic preparations are typically based on complex herbal compounds, minerals, and metal substances (perhaps under the influence of early Indian alchemy or ''rasashastra''). Ancient Ayurveda texts also taught surgical techniques, including rhinoplasty, kidney stone extractions, sutures, and the extraction of foreign objects. The main classical Ayurveda texts begin with accounts of the transmission of medical knowledge from the gods to sages, and then to human physicians. Printed editions of the '' Sushruta Samhita'' (''Sushruta's Comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euthymia (medicine)
In psychiatry and psychology, euthymia is a normal, tranquil mental state or mood. In those with bipolar disorder, euthymia is a stable mental state or mood that is neither manic nor depressive, yet distinguishable from the state of healthy people. Euthymia is also the “baseline” of other cyclical mood disorders like major depressive disorder (MDD), as well as borderline personality disorder (BPD) and narcissistic personality disorder (NPD). This state is the goal of psychiatric and psychological interventions. The term ''euthymia'' is derived from the Greek words “eu”, well, and “thymo”, soul or emotion. The word “thymos” also had four additional meanings: life energy; feelings and passions; desires and inclinations; and thought or intelligence. Euthymia is also derived from a verb, “euthymeo”, that means both “I am happy, in good spirits” and “I make others happy, I reassure and encourage”. This is the basis on which the first formal definition of e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dysthymia
Dysthymia ( ), also known as persistent depressive disorder (PDD), is a mental and behavioral disorder, specifically a disorder primarily of mood, consisting of similar cognitive and physical problems as major depressive disorder, but with longer-lasting symptoms. The concept was used by Robert Spitzer as a replacement for the term "depressive personality" in the late 1970s. In the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), dysthymia is a serious state of chronic depression, which persists for at least two years (one year for children and adolescents). Dysthymia is not a minor form of major depressive disorder, and for some may be more disabling. As dysthymia is a chronic disorder, those with the condition may experience symptoms for many years before it is diagnosed, if diagnosis occurs at all. As a result, they may believe that depression is a part of their character, so they may not even discuss their symptoms with doctors, family members or friends. I ...

Peptic Ulcer
Peptic ulcer disease (PUD) is a break in the inner lining of the stomach, the first part of the small intestine, or sometimes the lower esophagus. An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. The most common symptoms of a duodenal ulcer are waking at night with upper abdominal pain and upper abdominal pain that improves with eating. With a gastric ulcer, the pain may worsen with eating. The pain is often described as a burning or dull ache. Other symptoms include belching, vomiting, weight loss, or poor appetite. About a third of older people have no symptoms. Complications may include bleeding, perforation, and blockage of the stomach. Bleeding occurs in as many as 15% of cases. Common causes include the bacteria ''Helicobacter pylori'' and non-steroidal anti-inflammatory drugs (NSAIDs). Other, less common causes include tobacco smoking, stress as a result of other serious health conditions, Behçet's di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nizatidine
Nizatidine is a histamine H2 receptor antagonist that inhibits stomach acid production, and is commonly used in the treatment of peptic ulcer disease and gastroesophageal reflux disease. It was patented in 1980 and approved for medical use in 1988. It was developed by Eli Lilly. Brand names include Tazac and Axid. Medical use Nizatidine is used to treat duodenal ulcers, gastric ulcers, and gastroesophageal reflux disease (GERD/GORD), and to prevent stress ulcers. Adverse effects Side effects are uncommon, usually minor, and include diarrhea, constipation, fatigue, drowsiness, headache, and muscle aches. History and development Nizatidine was developed by Eli Lilly, and was first marketed in 1988. It is considered to be equipotent with ranitidine and differs by the substitution of a thiazole ring in place of the furan ring in ranitidine. In September 2000, Eli Lilly announced they would sell the sales and marketing rights for Axid to Reliant Pharmaceuticals. Subsequently, Re ...

H2 Receptor Antagonists
H2 antagonists, sometimes referred to as H2RAs and also called H2 blockers, are a class of medications that block the action of histamine at the histamine H2 receptors of the parietal cells in the stomach. This decreases the production of stomach acid. H2 antagonists can be used in the treatment of dyspepsia, peptic ulcers and gastroesophageal reflux disease. They have been surpassed by proton pump inhibitors (PPIs); the PPI omeprazole was found to be more effective at both healing and alleviating symptoms of ulcers and reflux oesophagitis than the H2 blockers ranitidine and cimetidine. H2 antagonists are a type of antihistamine, although in common use the term "antihistamine" is often reserved for H1 antagonists, which relieve allergic reactions. Like the H1 antagonists, some H2 antagonists function as inverse agonists rather than receptor antagonists, due to the constitutive activity of these receptors. The prototypical H2 antagonist, called cimetidine, was developed by Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoclonal Gammopathy
Monoclonal gammopathy, also known as paraproteinemia, is the presence of excessive amounts of myeloma protein or monoclonal gamma globulin in the blood. It is usually due to an underlying immunoproliferative disorder or hematologic neoplasms, especially multiple myeloma. It is sometimes considered equivalent to plasma cell dyscrasia. The most common form of the disease is monoclonal gammopathy of undetermined significance. Causes Causes of paraproteinemia include the following: * Leukemias and lymphomas of various types, but usually B-cell non-Hodgkin lymphomas with a plasma cell component. ** Myeloma ** Plasmacytoma ** Lymphoplasmacytic lymphoma * Idiopathic (no discernible cause): some of these will be revealed as leukemias or lymphomas over the years. ** AL amyloidosis Diagnosis These are characterized by the presence of any abnormal protein that is involved in the immune system, which are most often immunoglobulins and are associated with the clonal proliferation of lympho ...

Plasma Cell Dyscrasia
Plasma cell dyscrasias (also termed plasma cell disorders and plasma cell proliferative diseases) are a spectrum of progressively more severe monoclonal gammopathies in which a clone or multiple clones of pre-malignant or malignant plasma cells (sometimes in association with lymphoplasmacytoid cells or B lymphocytes) over-produce and secrete into the blood stream a myeloma protein, i.e. an abnormal monoclonal antibody or portion thereof. The exception to this rule is the disorder termed non-secretory multiple myeloma; this disorder is a form of plasma cell dyscrasia in which no myeloma protein is detected in serum or urine (at least as determined by conventional laboratory methods) of individuals who have clear evidence of an increase in clonal bone marrow plasma cells and/or evidence of clonal plasma cell-mediated tissue injury (e.g. plasmacytoma tumors). Here, a clone of plasma cells refers to group of plasma cells that are abnormal in that they have an identical genetic identity ...

Yin And Yang
Yin and yang ( and ) is a Chinese philosophy, Chinese philosophical concept that describes opposite but interconnected forces. In Chinese cosmology, the universe creates itself out of a primary chaos of material energy, organized into the cycles of yin and yang and formed into objects and lives. Yin is the receptive and yang the active principle, seen in all forms of change and difference such as the annual cycle (winter and summer), the landscape (north-facing shade and south-facing brightness), sexual coupling (female and male), the formation of both men and women as characters and sociopolitical history (disorder and order). Taiji (philosophy), Taiji or Tai chi () is a Chinese cosmological term for the "Supreme Ultimate" state of undifferentiated absolute and infinite potential, the oneness before duality, from which yin and yang originate. It can be compared with the old ''Wuji (philosophy), wuji'' (, "without pole"). In the cosmology pertaining to yin and yang, the mate ...
