Cabot's rings may be it the form of partial loops, loops, or figure eights. Their origin is not known and they may be artifacts. They are also rare. Cabot's ring; may be present in lead poisoning, pernicious anemia, thalassemia and other severe anemias. Cabot rings are red-purple staining threadlike filaments in the shape of a ring or figure 8 in the red blood cell, often in association with basophilic stippling. They may also appear as granules in a linear array rather than as complete rings. Cabot rings are thought to be microtubules from a mitotic spindle or remnants of the nuclear membrane. Cabot rings are seen in severe anemia including megaloblastic anemia, leukemia and lead poisoning. They are distinguished from the ring forms of Plasmodium by their larger size and by the absence of a red chromatin mass (Miale, J B: Laboratory Medicine Hematology 6th ed.,CV Mosby Co.,1982, p.488).
6 - Epstein-Barr virus, frequently referred to as EBV, is a member of the herpesvirus family and one of the most common human viruses.

Infants become susceptible to EBV as soon as maternal antibody protection (present at birth) disappears. Many children become infected with EBV, and these infections usually cause no symptoms or are indistinguishable from the other mild, brief illnesses of childhood. In the United States and in other developed countries, many persons are not infected with EBV in their childhood years. When infection with EBV occurs during adolescence or young adulthood, it causes infectious mononucleosis 35% to 50% of the time.Epstein-Barr virus is EBV binds to CD21 found on epithelial cells and B cells; however a large number of T suppressor cells and EBV specific cells are seen as atypical lymphocytes.

11 - Guthrie test is used for the diagnosis of PKU - a bacterial assay for phenylalanine. The Guthrie test, also known as the Guthrie bacterial inhibition assay, is a medical test performed on newborn infants to detect phenylketonuria, an inborn error of amino acid metabolism. The Guthrie test is named after Robert Guthrie, an American bacteriologist and physician, who devised it in 1962. The Guthrie test is a semiquantitative assay designed to detect elevated blood levels of the amino acid phenylalanine, using the ability of phenylalanine to facilitate bacterial growth in a culture medium with an inhibitor.A drop of blood is usually obtained by pricking the heel of a newborn infant in a hospital nursery on the second or third day of life. The blood is collected on a piece of filter paper and mailed to a central laboratory. A small disk of the filter paper is punched out and placed on an agar gel plate containing Bacillus subtilis and B-2-thienylalanine. Each gel holds 60-80 disks. The agar gel is able to support bacterial growth but the B-2-thienylalanine inhibits bacterial growth. However, in the presence of extra phenylalanine leached from the impregnated filter paper disk, the inhibition is overcome and the bacteria grow. Within a day the bacterial growth surrounding the paper disk is visible to the eye. The amount of growth, measured as the diameter of the colony, is roughly proportional to the amount of phenylalanine in the serum. The result is read by comparing the diameter of each sample disk's colony to the colonies of a series of reference disks with standard phenylalanine content included on each large plate. The Guthrie assay is sensitive enough to detect serum phenylalanine levels of 180-240 μmol/L (3-4 mg/dL). In healthy normal people, phenylalanine levels are usually under 120 μmol/L. In recent years it is gradually being replaced in many areas by newer techniques such as tandem mass spectrometry that can detect a wider variety of congenital diseases.

This anomaly occurs because the pain nerves deep in the intestines do not localize well to an exact spot on the abdominal wall, unlike pain nerves in muscles. Pain from a stomach ulcer or gallstone can be interpreted by the brain as pain from the stomach, liver, gall bladder, duodenum, or first part of the small intestine.

555 - Nikolsky's sign is a clinical dermatological sign in which blisters spread easily upon application of horizontal, tangential pressure to the skin. A positive Nikolsky's sign signifies a separation of epithelial cells either from one another or from the basement membrane, which is a layer of connective tissue to which epithelium usually adhered. This occurs in a number of conditions, including but not limited to the potentially fatal autoimmune skin disorder pemphigus vulgaris, staphylococcal scalded skin syndrome and toxic epidermal necrolysis.

559 - O'Donoghue's triad - An unhappy triad- terrible triad- is an injury to the knee. It commonly occurs in contact sports (such as American football). The mechanism for this injury occurs when a lateral (outside) force to the knee is received while the foot is fixed on the ground.
Structures in triad:
This scenario causes an injury to three knee structures:
* the anterior cruciate ligament
* the medial collateral ligament (or "tibial collateral ligament")
* the medial meniscus
The inclusion of the medial meniscus in the triad has been challenged.The reason that the medial collateral ligament and medial meniscus are injured together is because they are attached to one another in the knee joint.
560 - Freiberg disease is osteochondrosis of second metatarsal head; associated with avascular necrosis of metatarsal head; most patients are female.

The knee is flexed to ninety degrees on the affected side and the foot is rested on the unaffected knee. Holding the pelvis firm against the examination table, the affected knee is pushed towards the examination table, a maneuver which provides external rotation of the leg at the hip joint. If pain results, this is considered a positive Patrick's test and sacroiliitis is more likely. However, Patrick's test does not prove that sacroiliitis is causing the back pain, just increases the likelihood.This test is often performed along side Gaenslen's test.
564 - Gaenslen's test, also known as Gaenslen's Maneuver is a medical test used to detect musculoskeletal abnormalities and primary-chronic inflammation of the lumbar vertebrae and sacroiliac joint. This test is often used to test for Spondyloarthritis, sciatica, or other forms of rheumatism, and is often performed during checkup visits in patients who have been diagnosed with one of the former disorders. It is named after Frederick Julius Gaenslen, the orthopedic surgeon who invented the test. This test is often performed along side Patrick's test and Yeoman's test.To perform Gaenslen's test, the hip joint is flexed maximally on one side and the opposite hip joint is extended, stressing both sacroiliac joints simultaneously. This is often done by having the patient lying on his or her back, lifting the knee to push towards the patient's chest while the other leg is allowed to fall over the side of an examination table, and is pushed toward the floor, flexing both sacroiliac joints. The test is considered positive if the patient experiences pain while this test is performed, and may indicate a need for further testing, such as an x-ray or lumbar CT scan.

586 - Oliver's sign, or the tracheal tug sign, is an abnormal downward movement of the trachea during systole that can indicate a dilation or aneurysm of the aortic arch.
Oliver's sign is elicited by gently grasping the cricoid cartilage and applying upward pressure while the patient stands with his or her chin extended upward. Due to the anatomic position of the aortic arch, which overrides the left main bronchus, a downward tug of the trachea may be felt if an aneurysm is present.
The sign was first described by English military surgeon William Silver Oliver in 1878.
587 - Cardarelli's sign is an abnormal pulsation of the trachea that may be found in patients with a dilation or aneurysm of the aortic arch.
Cardarelli's sign can be felt by a physician pressing on the thyroid cartilage and displacing it to the patient's left. This increases contact between the left bronchus and the aorta, allowing systolic pulsations from the aorta to be felt at the surface if an aneurysm is present.
588 - Schmid metaphyseal chondrodysplasia is mutation in collagen X - mechanical pressure reduces growth.
589 - Macewen's sign is a sign used to help to diagnose hydrocephalus (accumulation of excess cerebrospinal fluid) and brain abscesses. Tapping (percussion) the skull near the junction of the frontal, temporal and parietal bones will produce a stronger resonant sound when either hydrocephalus or a brain abscess are present.The sign was discovered and described by Sir William Macewen (1848-1924), a surgeon and professor of the University of Glasgow, Scotland who also described Macewen's operation for inguinal hernia.
590 - The Kveim test, Nickerson-Kveim or Kveim-Siltzbach test is a skin test used to detect sarcoidosis, where part of a spleen from a patient with known sarcoidosis is injected into the skin of a patient suspected to have the disease. If granulomas are found (4-6 weeks later), the test is positive. If the patient has been on treatment (e.g. glucocorticoids), the test may be false negative. The test is not commonly performed, and in the UK no substrate has been available since 1996. There is a concern that certain infections, such as bovine spongiform encephalopathy, could be transferred through a Kveim test.It is named for the Norwegian pathologist Morten Ansgar Kveim, who first reported the test in 1941 using lymph node tissue from sarcoidosis patients. It was popularised by the American physician Louis Siltzbach, who introduced a modified form using spleen tissue in 1954. Kveim's work was a refinement of earlier studies performed by Nickerson, who in 1935 first reported on skin reactions in sarcoid.

598 - Courvoisier's law (or Courvoisier syndrome, or Courvoisier's sign) states that in the presence of a palpable gall bladder, jaundice is unlikely to be caused by gall stones. This is because gall stones are formed over a longer period of time, and this results in a shrunken, fibrotic gall bladder which does not distend easily. Therefore the gall bladder is more often enlarged in pathologies that cause obstruction of the biliary tree over a shorter period of time such as pancreatic malignancy.
599 - Ménière’s disease is 1. fluctuating sensorineural loss - classically involving low frequencies; 2. vertiginous episodes; 3. aural pressure; 4. tinnitus (frequently roaring); pathologic changes consist of dilation of the endolymphatic system that leads to degeneration of vestibular and cochlear hair cells.
600 - Darier's sign is a change observed after stroking the skin of a person with systemic mastocytosis or urticaria pigmentosa. In general, the skin becomes swollen, itchy and red. This is a result of compression of mast cells, which are hyperactive in these diseases. These mast cells release inflammatory granules which contain histamine. It is the histamine which is responsible for the response seen after rubbing the skin.Darier's sign is named after the French dermatologist Ferdinand-Jean Darier who first described it.
601 - Fordyce's spots, or Fordyce granules are small, painless, raised, pale or white spots or bumps 1 to 3 mm in diameter that may appear on the shaft of the penis or on the labia , as well as the inner surface and vermilion border of the lips of the face. They are common in men and women of all ages. They are named after an American dermatologist, John Addison Fordyce. On the head of the penis, they are called Tyson glands, not to be confused with pearly penile papules.

606 - In the fields of ophthalmology and optometry, the Hirschberg test, also Hirschberg corneal reflex test, is a screening test that can be used to assess whether a person has strabismus (ocular misalignment).A photographic version of the Hirschberg is used to quantify strabismus.It is performed by shining a light in the persons eyes and observing where the light reflects off of the corneas. In a person with normal ocular alignment the light lands on the centre of both corneas. For an abnormal result, based on where the light lands on the cornea, the examiner can detect if there is an exotropia (abnormal eye is turned out), esotropia (abnormal eye is turned in), hypertropia (abnormal eye higher than the normal one) or hypotropia (abnormal eye is lower than the normal one).
607 - Norwood procedure is for treating hypoplastic left heart syndrome - has 3 stages. Stage 1 - anastomosis of proximal main pulmonary artery to aorta - with aortic arch reconstruction and transection and patch closure of distal main pulmonary artery; modified right Blalock-Taussig shunt (subclavian artery to right PA) to provide pulmonary blood flow. ASD created to allow for adequate left to right flow. Stage 2 - Bidirectional Glenn shunt to reduce volume overload of single right ventricle. Stage 3 - modified Fontan procedure to correct cyanosis.
608 - Waterston-Cooley shunt is for treating tetralogy of Fallot - anastomosis of direct ascending aorta to right pulmonary artery; rarely performed currently.
609 - Hamman's sign is a crunching, rasping sound, synchronous with heartbeat, heard over the precordium in spontaneous mediastinal emphysema. Named for Johns Hopkins clinician Louis Hamman, M.D.This sound is heard best over the left lateral position. It has been described as a series of precordial crackles that correlate with the heart beat and not the respirations. Hamman's crunch is caused by pneumomediastinum or pneumopericardium. This is sometimes seen in patients with esophageal rupture.
610 - Homans sign is said to be present when passive dorsiflexion of the ankle by the examiner elicits sharp pain in the calf. It is caused by a thrombosis of the deep veins of the leg. This sign is frequently elicited in clinical practice because of the ease of use, although it is falling into disfavor because of risk of producing an embolism and because it is frequently positive in individuals without DVT. It is named for the American physician John Homans.To test for Homans' sign, flex the patient's knee slightly with one hand and, with the other, dorsiflex the foot. The complaint of calf pain with this procedure is a positive sign and often indicates venous thrombosis.. Absence of Homans' sign does not preclude venous thrombosis.

Sappey originally injected mercury into the skin of cadavers and showed that a line drawn just above the umbilicus would differentiate inguinal drainage and axillary drainage. Lesions within 2 cm of this line had bidirectional drainage. With the use of these techniques, drainage patterns not predicted by Sappey's original description of the cutaneous watershed areas have been frequently observed.

It generally indicates a poor prognosis.
894 - van buchem's syndrome - Endosteal hyperostosis (van Buchem's syndrome): Endosteal hyperostosis is usually inherited as autosomal recessive. Overgrowth and distortion of the mandible and brow become evident during midchildhood. Subsequently, cranial nerves become entrapped, leading to facial palsy and deafness. increased serum alkaline phosphatase . Life span is not compromised, stature is normal, and bones are not fragile. X-rays show widening and sclerosis of the calvaria, cranial base, and mandible. Diaphyseal endosteum in the tubular bones is thickened. Surgical decompression of entrapped nerves may be helpful.............Van Buchem's disease is a rare pathology with recessive transmission and variable expressivity characterised by a progressive cortical bone deposition. There are two types of this disease: Type I (Van Buchem's disease) progressive form for all life and with high level of PA (alkaline phosphate); Type II (Worth disease) the pathologic bone deposition stops at 20 years of age and the level of PA in the adult is normal. The most important histological feature is the bone hypertrophy with preservation of the lamellar frame. The bones interested are: skull vault, mandible, ribs, clavicle and diaphyseal portion of long bones. The first clinical manifestation became evident in childhood with progressive course. The narrowing of the cranial foramen is responsible of the progressive cranial nerves compression and the subsequent neurological signs. The disease is incurable; surgical treatment aims to reduce the intracranial pressure and to correct bones deformity. A clinical case in which the patient treated has esthetic problems but not neurological signs is presented.

It is due to a reciprocal translocation designated as t(9;22)(q34;q11), which means an exchange of genetic material between region q34 of chromosome 9 and region q11 of chromosome 22. The presence of this translocation is a highly sensitive test for CML, since 95% of people with CML have this abnormality (The remainder have either a cryptic translocation that is invisible on G-banded chromosome preparations, or a variant translocation involving another chromosome or chromosomes as well as the long arm of chromosomes 9 and 22). this 22 chromosome after translocation is called the PHILADELPHIA CHROMOSOME . However, the presence of the Philadelphia (Ph) chromosome is not sufficient to diagnose CML, since it is also found in acute lymphoblastic leukemia (ALL, 25–30% in adult and 2–10% in pediatric cases) and occasionally in acute myelogenous leukemia (AML).
