This secondary response occurs on 110 subsequent exposure to a previously encountered and recognized foreign antigen discount endep 75mg otc symptoms 8dpo. Autologous donation may take the form of predeposit or autotransfusion cheap 10mg endep with mastercard medications used for adhd, for example, intraoperative autotransfusion, hemodilution, or postoperative auto transfusion. Avidity (of an antiserum) A measure of the ability and speed with which an antiserum agglutinates red cells as a property of the combining constrant (K) Bombay phenotype The failure of an individual to express inherited A or B genes because of the lack of at least one H gene and the subsequent lack of the resulting H precursor substance. Compatibility test A series of procedures used to give an indication of blood group compatibility between the donor and the recipient and to detect irregular antibodies in the recipient’s serum. Cord blood Blood taken from the umbilical vein or the umbilical cord of a newborn Delayed hemolytic transfusion reaction A rapid increase in antibody concentration and destruction of transfused red cells a few days after transfusion usually due to low amount of antibody undetectable in pretransfusion tests on the recipient, which are stimulated to high titers by the transfusion of red cells possessing the offending antigen. Eluate In blood banking, the term denotes an antibody solution made by recovery into a fluid medium of antibodies that have been taken up by red cells (i. Immunoglobulin antibody containing globulins including those proteins without apparent anti body activity that have the same antigen specificity and are produced by similar cells. Incompatible transfusion Any transfusion that results in an adverse reaction in the patient (including reduced red cell survival). Inheritance The acquisition of characteristics by transmission of chromosomes and genes from ancestor to descendant. The observed or discernible characteristics of an individual Phenotype as determined by his or her genotype and the environment in which he or she develops. This form of destruction of erythrocytes is due to an IgG protein that reacts with the red blood cells in colder parts of the body and subsequently causes complement components to bin irreversibly to erythrocytes. The length of survival of blood ce4lls after infusion into the human body, believe to be related to the structural and metabolic status of the cell membran Prenatal. A possible cause of false- negative antigen- antibody reactions due to an excessive amount of antibody. Reagent red cells red cells used in laboratory testing Recessive gene A gene that gives rise only to its corresponding character when present in “double dose”(i. Secondary response A second response to exposure to a foreign antigen, resulting in the production of large amounts of antibody. Pseudoagglutination or the false cluming of erythrocytes when the cells are suspended in their own serum. This phenomenon resembles agglutination and is due to the presence of an abnormal protein in the serum, plasma expanders, such as dextran, or wharton’s jelly from cord blood samples. The complementary relationship between the binding sites of anibodies directed against determinants of a similar- type antigen. Sensitization(of red cells) The specific attachment of antibody to its antigenic receptors on red cells without agglutination or lysis. Sialic acid Any of a family of amino sugars containing nine or more carbon atoms that are nitrogen- and oxygen- substituted acylderivatives of neuraminic acid. It is a component of lipids, polysaccharides, mucoproteins and it is the main substance removed from the red cells by enzyme treatment. The complementary relationship between the binding sites of anibodies directed against determinants of a similar- type antigen. A type of enzyme that catalyzes the transfer of a monosaccharide molecule from a donor substrate to the precusrsor substance.

Opening of the mouth requires the combination of two motions at the temporomandibular joint endep 10 mg with mastercard symptoms stomach ulcer, an anterior gliding motion of the articular disc and mandible and the downward hinging of the mandible generic 25mg endep visa medicine interaction checker. What is the initial movement of the mandible during opening and how much mouth opening does this produce? This is a ball-and-socket joint formed by the articulation between the head of the humerus and the glenoid cavity of the scapula (Figure 9. However, this freedom of movement is due to the lack of structural support and thus the enhanced mobility is offset by a loss of stability. The large range of motions at the shoulder joint is provided by the articulation of the large, rounded humeral head with the small and shallow glenoid cavity, which is only about one third of the size of the humeral head. The socket formed by the glenoid cavity is deepened slightly by a small lip of fibrocartilage called the glenoid labrum, which extends around the outer margin of the cavity. The articular capsule that surrounds the glenohumeral joint is relatively thin and loose to allow for large motions of the upper limb. Some structural support for the joint is provided by thickenings of the articular capsule wall that form weak intrinsic ligaments. These include the coracohumeral ligament, running from the coracoid process of the scapula to the anterior humerus, and three ligaments, each called a glenohumeral ligament, located on the anterior side of the articular capsule. However, the primary support for the shoulder joint is provided by muscles crossing the joint, particularly the four rotator cuff muscles. These muscles (supraspinatus, infraspinatus, teres minor, and subscapularis) arise from the scapula and attach to the greater or lesser tubercles of the humerus. As these muscles cross the shoulder joint, their tendons encircle the head of the humerus and become fused to the anterior, superior, and posterior walls of the articular capsule. The thickening of the capsule formed by the fusion of these four muscle tendons is called the rotator cuff. Two bursae, the subacromial bursa and the subscapular bursa, help to prevent friction between the rotator cuff muscle tendons and the scapula as these tendons cross the glenohumeral joint. In addition to their individual actions of moving the upper limb, the rotator cuff muscles also serve to hold the head of the humerus in position within the glenoid cavity. By constantly adjusting their strength of contraction to resist forces acting on the shoulder, these muscles serve as “dynamic ligaments” and thus provide the primary structural support for the glenohumeral joint. Repetitive use of the upper limb, particularly in abduction such as during throwing, swimming, or racquet sports, may lead to acute or chronic inflammation of the bursa or muscle tendons, a tear of the glenoid labrum, or degeneration or tears of the rotator cuff. Because the humeral head is strongly supported by muscles and ligaments around its anterior, superior, and posterior aspects, most dislocations of the humerus occur in an inferior direction. This can occur when force is applied to the humerus when the upper limb is fully abducted, as when diving to catch a baseball and landing on your hand or elbow. Inflammatory responses to any shoulder injury can lead to the formation of scar tissue between the articular capsule and surrounding structures, thus reducing shoulder mobility, a condition called adhesive capsulitis (“frozen shoulder”). Elbow Joint The elbow joint is a uniaxial hinge joint formed by the humeroulnar joint, the articulation between the trochlea of the humerus and the trochlear notch of the ulna. The articular capsule of the elbow is thin on its anterior and posterior aspects, but is thickened along its outside margins by strong intrinsic ligaments. This arises from the medial epicondyle of the humerus and attaches to the medial side of the proximal ulna. The strongest part of this ligament is the anterior portion, which resists hyperextension of the elbow. The ulnar collateral ligament may be injured by frequent, forceful extensions of the forearm, as is seen in baseball pitchers. Reconstructive surgical repair of this ligament is referred to as Tommy John surgery, named for the former major league pitcher who was the first person to have this treatment. This arises from the lateral epicondyle of the humerus and then blends into the lateral side of the annular ligament.

The bulk of the placenta fetalis consists of outgrowths of villi from the surface of the chorionic plate generic endep 10 mg without a prescription treatment 001. The villi are sectioned in many 73 different planes order endep 50 mg on-line medicine dictionary pill identification, and their attachment to the chorionic plate may not be evident. Attached to the inner (fetal) surface of the chorionic plate is the amnion, consisting of an inner squamous amniotic epithelium and an outer layer of avascular mesoderm. Study the chorionic villi in detail, and identify all of the layers that separate the maternal and fetal blood. Gases, nutrients, metabolites and other substances must pass through these layers to move from one circulation to the other. In life maternal blood fills the intervillous space, but it is generally washed out during tissue preparation. Note the loose appearance of the cells forming the cores of the villi, and compare this with the condition in the villi at 6 months gestational age. Occasional nucleated fetal red blood cells, characteristic of earlier stages, can still be observed in the fetal vessels of the villi. Note the abundance and location of the fetal capillaries, the sparsity of the cytotrophoblast, and the nature of the syncytiotrophoblast. Be certain that you know the layers that form the separation between fetal and maternal blood in the placenta. This network of ducts begins at the nipple with the excretory lactiferous duct, which branches as it extends into the collagen and adipose tissue of the breast until it eventually branches into terminal duct lobular units. The terminal duct lobular unit consists of interlobular stroma, interlobular duct, terminal duct and acini, and surrounding fat. With higher power, note that the ducts and acini are lined by simple cuboidal or columnar epithelium and surrounding myoepithelial cells. There is abundant connective tissue with embedded lactiferous ducts, ending in minimal lobule formation #69 Breast, Lactating, Osmium fixation Unsaturated lipid in the apical cytoplasm of the alveolar cells and in the milk in the lumina is stained black by reduced osmium tetroxide. Because osmium penetrates very poorly the tissue is well stained only at the periphery of the section. The connective tissue surrounding the alveolus is much more delicate (although compressed here) and is continuous with the papillary layer of the dermis. The digestive system consists of the oral cavity, the pharynx, the alimentary tract (canal), and the anal canal. There are both intrinsic and extrinsic glands, which may secrete digestive enzymes or mucus to facilitate the digestion and transport of ingested food. The extrinsic digestive glands are the major salivary glands including the parotid, sublingual and submandibular (submaxillary) glands; the pancreas; and the liver. Proceeding outward from the lumen these are: (1) the mucosa (mucous membrane), (2) the submucosa, (3) the muscularis (muscularis externa), and (4) the adventitia or serosa. The mucosa has three components: (a) the epithelium and its underlying basement membrane, (b) a thin underlying layer of loose, cellular connective tissue, the lamina propria, and (c) a relatively thin layer of smooth muscle called the muscularis mucosae. The submucosa is composed of a layer of dense, irregularly arranged connective tissue that contains nervous tissue (the submucosal plexus of Meissner) as well as blood vessels. The muscularis externa consists of at least 2 layers of smooth muscle, an inner circular and outer longitudinal layer. Connective tissue separating the muscle layers contains nerves (myenteric plexus of Auerbach) and blood vessels. The major salivary glands arise as invaginations of the oral epithelium during the second month of embryonic development, and they are involved with the secretion of the watery, mucus, and enzymatic content of saliva. The three types of cell within the taste bud are sensory, supporting, and basal, but you should not attempt to distinguish them.

Students should become familiar with the Mental Status Exam as it replaces the physical exam component of the patient interview and note cheap endep 10 mg with mastercard medications and mothers milk 2016. You will also have the opportunity to participate in hospital consult services endep 75 mg with visa symptoms umbilical hernia, where you will be able to see how somatic disease and psychiatric illness interface. For new patients, one person on the team is expected to “pick up” the patient and interview him or her during rounds. You are also expected to talk, spend time with, and get to know your other patients and write progress notes on them as well. You may also be required to complete one or two topic presentations—in some past years, all students have been required to complete one presentation on psychiatric aspects of a chronic disease. Be extra careful about dressing professionally on psychiatry; remember that cleavage or flashy clothes might give the wrong signal to a confused patient. Some helpful hints for psych: • This is the only rotation where you don’t shake your patient’s hand when you walk in the room. This means never putting the patient between you and the door, never doing anything you feel uncomfortable with, and adhering to any guidelines that your residents and attendings create. Mental Status Exam: The psych H&P is similar to the general H&P, but it is important to pay extra attention to the past psych history, family psych history, drug and alcohol history, and social history. Behavior: Include gestures, abnormal or idiosyncratic movements (akathisia, automatisms, catatonia, choreoathetoid movements, compulsions, dystonias, tardive dyskinesia, tics, tremors, etc. Cooperation/reliability: Pay attention to patients’ cooperation/attentiveness to the interview and their attitude/demeanor. Speech: Note rate, quantity, quality (volume, rhythm), and form, as well as any difficulty speaking (i. Thought Process: This is the form or structure of the patient’s thinking as opposed to the actual content. Impaired thought processes include looseness of associations, flight of ideas, word salad, thought blocking (sudden interruption of thought and speech), racing, etc. Includes delusions, suicidal/homicidal ideation, paranoia, somatic or religious pre-occupation, other obsessions, grandiosity, helplessness, ideas of reference, ideas of thought control or thought broadcasting, thought insertion, beliefs of unusual powers, phobias, fears, feelings of worthlessness or guilt, and feelings of being punished. This is the internal emotional state that you believe to be present—may not match the patient’s affect. The sites also vary in terms of hours and expectations, so try to find out from your friends about the various sites. Throughout the rotation, you will meet regularly for lectures that will cover a lot of the material you will need for the shelf. The inpatient experiences should be very similar to your core rotation in inpatient medicine in that you will help admit, work up, manage, and follow specific patients throughout the course of their admission. On a consult service, you will see how neurologic issues may affect patients on other specialty services. Presentations and notes should follow the standard format, with the addition of a directed neurologic history, comprehensive neurologic exam, and underlying appreciation for relevant neuroanatomy. You may be asked to prepare a topic presentation to present to your team—see the “Sample Documents” packet for an example of a Neurology topic presentation. With pediatric patients, keep in mind that at different ages, some aspects of the neuro exam are not applicable or need to be approached in a different manner. You may want to get a copy of the Denver developmental 51 milestones sheet to get an idea of what is appropriate behavior given a child’s age. Neurologic Exam Cranial Nerves: I: Olfactory: most do not try to test this; if you are really on top of your game, you may have a vial of something with an odor. As a student, you can stuff your white coat with a light pen, toothpicks or wooden cotton swabs, reflex hammer (or use the end of your stethoscope), tuning forks (if you really have it together), and an ophthalmoscope (if you have one or have friends from whom you can borrow one— definitely not necessary though). Ophthalmology The Ophthalmology week begins with an introductory session on the eye exam, use of the slit lamp, and looking at each other’s fundi.

With >100% annual blood examination rate buy endep 25 mg otc treatment zoster ophthalmicus, all suspected cases are tested and all reported cases are confirmed order 25 mg endep otc medicine 02. The average number of reported malaria cases fell from around 12 000 annually during 2000–2002 to 7000 in 2009. Based on the substantial progress achieved in recent years, the country aims to eliminate malaria by the end of 2015. The number of probable and confirmed malaria cases reported annually decreased from 480 515 during 2001–2005 to only 81 812 cases in 2009 (83% decline). During same period a similar trend was observed in the confirmed malaria admissions and deaths: malaria admissions decreased from 29 059 to 2264 (92% reduction) and malaria deaths fell from 1370 to 46 (96% reduction). Diagnostic capacity has progressively improved in recent years and the annual examination rate reached 14% in 2009. The resurgence of uncomplicated outpatient malaria cases was greater than that of severe malaria cases and deaths. Outpatient confirmed malaria cases doubled in 2009 compared to 2008 but interpretation of the data is confounded by a 61% increase in those tested in 2009. Malaria confirmed cases decreased from the annual average of 38 655 during 2000–2005 to 3893 cases in 2009 (90% decline). In the same period, malaria admissions fell from an annual average of 12 367 to 1514 in 2009 (88% decline) and malaria deaths also fell from 162 to 23. However, there was a doubling of outpatient confirmed cases and inpatient malaria cases in 2009 compared to 2008. Malaria transmission tends to be highly seasonal and unstable with the peak occurring between October and April; over 70% of the cases are still due to P. While an annual average of 1700 confirmed malaria cases was reported during 2003–2009, the number of indigenous cases fell from 467 in 2006 to 58 cases in 2009, a reduction of 88%. Saudi Arabia shows strong political commitment to the Elimination of Malaria from the Arabian Peninsula, endorsed in 2005 by all bordering countries. Only 4% of the population is at high risk of malaria and 6% at low risk, while 90% live in malaria-free areas. Confirmed malaria cases have decreased from an annual average of 36 360 during 2000–2005 to 6072 cases in 2009 (83% reduction). During same period, with 100% testing of suspected cases, 95% of the reported cases were indigenous and malaria cases declined from an annual average of 55 640 to just 558 cases. Having achieved a substantial reduction in the malaria burden, Sri Lanka is once again in a position to envisage malaria elimination. With a 100% confirmation rate, the number of reported malaria cases decreased from an annual average of 11 449 cases during 2000–2005 to 1371 in 2009 (88% decline). Confirmed malaria cases have decreased from an annual average of 652 during 2000–2005 to only 106 cases in 2009 (84% decline). In the same period, malaria admissions decreased from 1026 to 230 and malaria deaths fell from 32 to 13 (over 60% reduction for both). Morbidity and mortality have been substantially reduced, with a decrease of *75% in the numbers of malaria cases, inpatient malaria cases and deaths in 2009 compared to the average for 2000–2004. Analysis of subnational inpatient data indicate that the higher totals in 2009 resulted from increases in Luapula and Eastern provinces.
