A 3-year-old boy presents with cyanosis diagnosed with a primary heart tumor that and shortness of breath that develops when is causing a "ball-valve obstruction" of her he plays with friends. Chest (8) Leiomyoma radiography reveals a boot-shaped heart, (e) Lipoma normal heart size, and a right aortic arch. Which of the following is the dependent peripheral edema in her most likely diagnosisfi She has long-standing (A) Coarctation of the aorta chronic obstructive lung disease and a (8) Patent ductus arteriosus long history of cigarette smoking. The most likely diagnosis is pnea on exertion, orthopnea, paroxysmal (A) carcinoid heart disease. Rupture of the left ventricle, a catastrophic complication of acute myocardial infarction, usually occurs when the necrotic area has the least tensile strength, about 4-7 days after an infarction, when repair is just beginning. The risk of arrhythmia is greatest within the first 6 hours after myocardial infarct. Arrhythmias are the most important early complication of acute myocardial infarction, accounting for almost 50% of deaths shortly after myocardial infarction. Myocardial, or pump, failure and mural thrombosis are other complications that may develop as a result of permanent damage to the heart after infarct. Ventricular aneurysms may develop in the fibrotic scar within 3-6 months after myocardial infarct. Acute rheumatic fever manifests most commonly in patients 5-15 years of age with migratory polyarthritis, pancarditis, subcutaneous nodules, erythema marginatum, and Sydenham chorea. This is a case of paradoxical embolism, which denotes the passage of an embolus of venous origin into the arterial circulation, by way of a right-to-left shunt. Ordinarily, atrial septal defects result in a left-to-right shunt across the atrial septum, but over time may develop into a right-to-left shunt. Cyanosis, which occurs when the arterial concentration ofreduced hemoglobin exceeds 5 mg/mL, is seen with a right-to-left shunt, in which venous blood gains direct access to the arterial circulation. Because of the jelly-like appearance and myxoid histology similar to that of some organized thrombi, the neoplastic nature of this lesion was debated for many years; however, it is now generally believed that myxoma is a true neoplasm. Due to its location, complications may develop due to physical obstruction ofblood fow through the mitral valve, resulting in symptoms of congestive heart failure. The term cor pulmonale refers to right ventricular hypertrophy caused by pulmonary hypertension secondary to disorders of the lungs or pulmonary vessels. Therefore, although in general, the most common cause ofright-sided heart failure is left-sided heart failure, cor pulmonale wth right-sided heart failure is due to an intrinsic disease originating in the lungs. Anemia is a decrease in whole body red cell mass, a definition that precludes relative decreases in red blood cell count, hemoglobin, or hematocrit, which occur when the plasma volume is increased. Anemia ofpregnancy is not anemia but rather is a manifestation ofincreased plasma volume. Within the first few hours ofacute blood loss, prior to hemodilution (compensatory increase in plasma volume), there may be no decrease in the hemoglobin, hematocrit, and red blood cell count because of a parallel loss of both red cells and plasma. Most often causes are menorrhagia orbleeding gastrointestinal lesions, such as carcinoma ofthe colon in the United States or hookworm disease in less developed countries. Peripheral blood andbone marrowfndings are identical in all forms ofmegaloblastic anemias. Peripheral blood fi (1) Pancytopenia (decreased red cells, white cells, and platelets) fi (2) Oval macrocytosis. The chronic gastritis is also associated with: (a) Achlorhydria (absent gastric free hydrochloric acid) (b) Anti-intrinsic factor and antiparietal cell antibodies (c) Increased incidence of gastric carcinoma (3) Clinical findings (a) Insidious onset with extreme reduction of red blood cell count; in older persons may be preceded by a lengthy subclinical period in which clinical manifestations are minimal. These pernicious anemia-like illnesses can be caused by a number of other mechanisms thatresult in vitamin B 2I deficiency. Anemia of chronic disease can be secondary to a wide variety of primary disorders, including rheumatoid arthritis, renal disease, or chronic infection. In addition, it can be caused by autoimmune dysfunction ofcytotoxic T cells, and it can also be induced by several other etiologic agents: a. It may be signaled by leukoerythroblastosis, in which small numbers of nucleated red cells and immature granulocytic precursors are seen in the peripheral blood smear. Increased red cell destruction with liberation ofhemoglobin or its degradation products is manifested by:; a. Hyperbilirubinemia maylead to pigment-containing gallstones as a late complication. Hemoglobinemia and hemoglobinuria, which, along with methemalbuminemia and hemosiderinuria, occur if red cell destruction is very rapid and within the circulation (intravascular hemolysis). Disappearance of serum haptoglobins, a group of hemoglobin-binding proteins, which combine with liberated hemoglobin and are no longer demonstrable. Because reticulocytes are larger than other red cells, the MeV may be modestly increased (up to about 105 f. Polychromatophilia (increased number of somewhat larger red cells that stain with a bluish cast, roughly equivalent to increased reticulocyte count) B. Extracorpuscular hemolytic anemia is marked by defects, most often acquired, of the extraerythrocytic environment, such as circulating antibodies or an enlarged spleen. Immune hemolytic anemias are clinically suggested by hemolytic anemia of recent onset. Warm antibody autoimmune hemolytic anemia is the most common form of immune hemolytic anemia. This anemia is mediated by IgG autoantibodiesthatreactwith red cell surface antigens. The anemia is often secondary to underlying disease states such as systemic lupus erythematosus, Hodgkin disease, or non-Hodgkin lymphomas. Clinical characteristics include the following: (1) General features of hemolytic anemia (2) Spherocytosis due to progressive loss of membrane protein by serial passage of antibody-coated red cells through the spleen fi (3) Positive direct Coombs test reflecting the binding of IgG autoantibody to the red cell surface 2. Acute cold agglutinin disease is often mediated by antibodies with specifcity for the I blood group antigen. It is often a complication of infectious mononucleosis or Mycoplama pneumoniaeinfection. Characterized clinically by agglutination and hemolysis in tissue sites exposed to the cold, it may be associated with Raynaud phenomenon. These cases are marked by chronic hemolytic anemia exacerbated by cold weather, punctuated by episodes ofjaundice, sometimes with hemoglobinemia and hemoglobinuria. Hemolytic disease of the newborn (erythroblastosis fetalis) occurs when maternal antibodies cross the placenta and react with fetal red cells, resulting in fetal hemolytic anemia. In the most fequently occurring form ofR-mediated hemolytic disease of the newborn, the mother is typed as d and the fetus as D. Paroxysmal nocturnal hemoglobinuria is an uncommon acquired intracorpuscular defect. Characteristics include increased sensitivity to complement-induced red cell lysis, resulting in intravascular hemolytic anemia, pancytopenia, and an increased incidence of venous thrombosis. This anemia is characterized by spherocytes (sphere-shaped erythrocytes) that are selectively trapped or sequestered in the spleen. The cause is a variety of molecular defects in the genes coding for spectrin, ankyrin, protein 4. Hereditary elliptocytosis (ovalocytosis) is an autosomal dominant disorder characterized by elongated, oval red cells. This X-linked disorder occurs in approximately 10% ofAfrican Americans and also in persons of Mediterranean origin. Pyruvate kinase deficiency is the second most common enzye deficiency hemolytic anemia. This autosomal recessive disorder is characterized by hereditary nonspherocytic hemolytic anemia. General considerations fi (1) Approximately 7% of African Americans carry the hemoglobin S gene. In some parts ofAfrica, more than one third ofthe population is affected; it is thought that the hemoglobin S gene confers resistance to falciparum malarial infection. When heterozygous, they result in disease only when coinherited with other abnormal hemoglobins, most often hemoglobin S. These disorders have increased significantly in incidence in the United States in recentyears and are now more common than hemoglobin S disorders in some urban areas. Clinical and laboratory manifestations are similar to those ofhemoglobin C disorders. Thalassemias fi this heterogeneous group ofgenetic disorders is characterized by deficient production ofeither aor [-globin chains of hemoglobin. They are widespread throughout the world, occurring with high frequency in Africa, India, Southeast Asia, and the Mediterranean area. They are caused by defects in the promoter sequence, in introns, or in coding regions of the [-globin gene. They are caused by deletions of one or more of the four a-globin genes (see Table 11-2). In normal persons, there is duplication of the a-globin gene, with a pair of identical a-globin genes on each member of the chromosome 16 pair. In these instances, partial occlusion of small vessels is the cause of the mechanical disruption of the erythrocytes. The peripheral blood smear of an anemic I-year-old child is shown in the illustration. A primiparous D-negative (Rh-negative) mother has just delivered a D-positive child. The most likely cause (8) Anti-D IgG to mother of the anemia is (e) D-positive red cells to child (A) a red cell membrane protein defect. His father and paternal aunt had a similar illness that was treated successflly by splenectomy. The spleen of the patient in question 8 (B) Decreased mean corpuscular volume would be expected to be (e) Increased direct (conjugated) serum (A) enlarged. In addition, his indirect (A) Decreased blood pressure (unconjugated) bilirubin is Significantly (B) Decreased hematocrit elevated.

Without adequate learning and teaching resources, it can be an overwhelming challenge for Estudents and faculty. This new edition of Medical Terminology: An Illustrated Guide meets that challenge with a clear organizational scheme, full-color illustrations with a strong clinical focus, a wide array of effective pedagogical features, a variety of activities, and useful ancillaries to make teaching and learning more effective. Organization and Approach Medical Terminology: An Illustrated Guide takes a stepwise approach to learning the language of medical terminology. In Part 3, the chapters begin with an overview of the normal structure and function of the system under study, followed by a list of key terms with definitions (the roots used in the accompanying chapter exercises are included in these definitions). Word parts related to each topic are then presented and illustrated, along with exercises on the new material. New to this edition is information on complementary and alternative medicine and special interest boxes with information on word derivations and usage. Because it is based mainly on Greek and Latin words, medical terminology is Mconsistent and uniform throughout the world. Moreover, like the jargon that arises in all changing fields, it is always expanding. Think of the terms that have been added to our vocabulary with the development of computers, such as software, megabyte, search engine, e-mail, chat room. The Greek root nephr and the Latin root ren are used to refer to the kidney, an organ of the urinary system. We find both the Greek root nephr and the Latin root ren used in words pertaining to the kidney (Fig. You will sometimes have to consider the context of a word before assigning its meaning. Some compound medical words are cardiovascular (pertaining to the heart and blood vessels), urogenital (pertaining to the urinary and reproductive systems), and lymphocyte (a white blood cell found in the lymphatic system). Word Derivations As mentioned, most medical word parts come from Greek (G) and Latin (L). For those interested in the derivations of medical words, a good medical dictionary will provide this information. Only one pronunciation for each word is given here, but be prepared for differences. When exthe word gynecology is usually pronounced treme, some alternate pronunciations can with a hard g in the United States, but in many sound like a foreign language. Silent Letters and Unusual Pronunciations A silent letter or unusual pronunciation can be a problem, especially if it appears at the start of a word that you are trying to look up in the dictionary. Usage varies in different institutions, and the same abbreviation may have different meanings in different fields. An acronym is an abbreviation formed from the first letter of each word in a phrase. These are listed at the end of each chapter, but a complete alphabetical list appears in Appendix 2. Words Ending In x When a word ending in x has a suffix added, the x is changed to a g or a c. Later, for a persistent dry cough and problems resulting from a fractured nose, she was referred to an otorhinolaryngologist. She made an appointment with a naturist practitioner who specialized in homeopathy and herbal medicine. Before her appointment, she browsed in the Nutra-Medica Shop, which carried nutritional supplements, vitamin and mineral products, homeopathic remedies, and herbal formulas. Use the fiash cards at the back of this book to find the meaning of the word part endo-. Use Appendix 3 to find the meaning of the word part homeo. When the word larynx has a suffix added, the x is changed to a. The be added to imply that something is not right on suffix thon is taken from the name of the target, as in largish, softish, oldish.

The plural endings listed in column 2 are substituted for the word endings in column 1. Some Exceptions to the Rules There are exceptions to the rules above for forming plurals, some of which will appear in later chapters. For example, the plural of carcinoma (a type of cancer) should be carcinomata, but carcinomas is commonly used. He also had a mild fever, night sweats, occasional dizziness, double vision, and mild crampy abdominal pain accompanied by intermittent diarrhea. He had symmetrical areas of edema (swelling) around both knees and tenderness over both patellae (kneecaps). The ulceration on his left lateral ankle had a ring of necrosis (tissue death) surrounding an area of granulation tissue. There is just one short additional chart of prefixes related to position in Chapter 5 on body structure. The meanings of many of these prefixes will be familiar to you from words that are already in your vocabulary. To unify (U-ni-fi) means to make two or more parts into part(s). Peritoneal dialysis, in which the dialysate Skin is infused into the peritoneal cavity by gravity. Exercise 3-5 Match the following terms and write the appropriate letter to the left of each number: 1. A unicellular organism is composed of cell(s). Postoperative care included maintaining the left hip in abduction, blood and fiuid replacement, physical therapy, and vigilance for development of avascular necrosis and possible dislocation. He had an open reduction and internal fixation with a compression screw and side plate with screws. He was discharged to a rehabilitation facility for several weeks of physical therapy and assistance with activities of daily living, such as personal hygiene, dressing, eating, ambulating, and toileting. The adjective for the operative time span from decision for surgery to placement on the operating room table is. The adjective for the operative time span from placement on the operating room table until transfer to postanesthesia recovery unit or intensive care unit is. Cells carry out metabolism, the sum of all of the physical and chemical activities that occur in the body. The main carbohydrate is the sugar glucose, which circulates in the blood to provide energy for the cells. Some hormones are derived from lipids, and adipose (fat) tissue is designed to store lipids. Within the cytoplasm that fills the cell are subunits called organelles, each with a specific function. Genes control the formation of enzymes, the catalysts needed for metabolic reactions. Sex cells (egg and sperm) divide by another process (meiosis) that halves the chromosomes in preparation for fertilization. Tissues Cells are organized into four basic types of tissues that perform specific functions (Fig. Mucous membranes secrete mucus, a thick fiuid that lubricates surfaces and protects underlying tissue. Serous membranes, which secrete a thin, watery fiuid, line body cavities and cover organs. The term is also ratory, as compared with studies done in livapplied to the specimen itself.

A myxocyte is found in tissue that secretes. The study of form and structure. The specimens included several small containers of pink-tinged cloudy fiuid labeled pelvic lavage (washing) for cytology, which R. She took all of the tissue specimens to the pathology laboratory for gross and microscopic evaluation. A test tube half-filled with a cloudy gel and a cotton-tipped applicator labeled swab of pelvic fiuid for culture and sensitivity and Gram stain was taken to the microbiology laboratory to be streaked on a culture plate and incubated to look for growth. Any organisms that grew out would be Gram-stained and tested for sensitivity to antibiotics that might be used in treatment. Three words that contain a root that means attract, absorb: 11. In this stance, the terms illustrated in Figure 5-1 and listed in Display 5-1 are used to designate relative position. A frontal plane, also called a coronal plane, is made at right angles to the midline and divides the body into anterior and posterior parts. The dorsal cavity contains the brain in the cranial cavity and the spinal cord in the spinal cavity (canal). The uppermost ventral space, the thoracic cavity, is separated from the abdominal cavity by the diaphragm.

More specific information about how diseases affect individual systems and how these diseases are treated will be presented in Part 3. Diseases can Abe grouped into a number of different but often overlapping categories. Common examples include arthritis, cardiovascular problems, and certain respiratory disorders such as emphysema. Structural malformations such as congenital malformations, prolapse (dropping), or hernia (rupture) may also result in degenerative changes. In sickle cell anemia, red Some are named for the places where they were blood cells become distorted into a crescent first found, such as Lyme disease for Lyme, shape when they give up oxygen.

The interaction between Taraxacum mongolicum and ciprofloxFurther study is required to discover if, and under what circumacin is based on experimental evidence only. Effects of Taraxacum mongolicum on the bioavailability and Experimental evidence disposition of ciprofloxacin in rats. In a study in rats, an aqueous extract of Taraxacum mongolicum (2g crude drug/kg) significantly reduced the maximum concentration of a single 20-mg/kg oral dose of ciprofloxacin by 73% when compared with administration of oral ciprofloxacin alone. The reason for the reduced maximum level and prolonged elimination half-life is uncertain. It is also used as an sible, and therefore additive antiplatelet effects might occur anti-inflammatory and for the treatment of cancer and liver if danshen is taken with conventional antiplatelet drugs, disease. However, these effects do not appear to be nifedipine, but no clinically relevant pharmacokinetic interclinically relevant. The interaction between danshen and digoxin is based on D Importance and management experimental evidence only. Both extracts exhibited concentrationdependent inhibitor effects on P-glycoprotein. In a study in mice, a commercial pharmaceutical extract and an Therefore if danshen is taken by a patient receiving digoxin it may aqueous extract of danshen had no effect on nifedipine oxidation. In be prudent to be alert for symptoms of raised digoxin levels, such as contrast an ethyl acetate extract of danshen (which is not used as a bradycardia, and consider monitoring levels, should this occur. Yu X-Y, Zhou Z-W, Lin S-G, Chen X, Yu X-Q, Liang J, Duan W, Wen J-Y, Li X-T, cause vasorelaxant effects. Danshen + Food Importance and management Evidence for an interaction between nifedipine and danshen appears to be limited to experimental studies, which suggest that the type of No interactions found. A pharmacodynamic interaction Danshen + Herbal medicines may occur, because both nifedipine and danshen have calciumchannel-blocking effects. It is difficult to find an example of a clinically important interaction (with conventional Danshen can falsify the results of serum immunoassay methods drugs) due to this mechanism alone. Danshen can falsify some laboratory measurements of digoxin Importance and management because it contains digoxin-like immunoreactive components. There may be a more clinically significant presence of danshen, whereas a microparticle enzyme immunoassay interaction with low-dose aspirin, as both it and danshen have (Abbott Laboratories) gave falsely low readings. In vivo digoxin-like Danshen does not appear to affect the pharmacokinetics of immunoreactivity in mice and interference of Chinese medicine Danshen in serum theophylline. Danshen + Salicylates Importance and management the available evidence is limited, but seems to suggest that the dose the interaction between danshen and salicylates is based on of theophylline will not need to be altered in patients also taking experimental evidence only. Experimental evidence (a) Protein binding In vitro experiments show that danshen can increase free salicylate Danshen + Tolbutamide concentration by displacing salicylate from binding to albumin proteins. This study also suggests that lower dose of 500mg/kg, which suggests that a clinical interaction is danshen is unlikely to affect the metabolism of other drugs that are unlikely at the recommended dose of 90mg/kg of Kangen-Karyu substrates of this isoenzyme.

The neutrophils release lysosomal enzymes, resulting in tissue damage, which can also result from other substances released by neutrophils, including prostaglandins, kinins, and free radicals. Serum sickness is a systemic deposition of antigen-antibody complexes in multiple sites, especially the heart, joints, and kidneys. Systemic lupus erythematosus is also an example of a multisystem immune complex disease. Arthus reaction is a localized immune complex reaction that occurs when exogenous antigen is introduced, either by injection or by organ transplant, in the presence ofan excess of preformed antibodies. Polyarteritis nodosa is a generalized immune complex disease especially involving smalland medium-sized arteries. Adverse immune responses can be suppressed by immunosuppressant drugs, radiation, or recipient T-cell depletion. Rejection is a localized Arthus reaction marked by acute infammation, fibrinoid necrosis of small vessels, and extensive thrombosis. When antibody-mediated mechanisms are prominent, it may show evidence of arteritis with thrombosis and cortical necrosis. Rejection is characterized histologically bymarked vascular fibrointimal proliferation, often resulting in a small, scarred kidney. The rejection of "foreign" host cells by engrafted T and B cells is characteristic. This disorder occurs in male infants butusually is not manifest clinically until after 6 months of age because of the persistence of maternal antibodies. Absence of plasma cells in tissue results in virtual absence of serum immunoglobulins. A propensity for recurrent bacterial infections with organisms, such as pneumococci, streptococci, staphylococci, and Haemophilus inJluenzae. Most often, the disorder is asymptomatic, but it may be characterized by occasional anaphylactic reactions to transfused blood. Common variable immunodeficiency, this diverse group of disorders is caused by failure of terminal B-cell maturation, resulting in diminution in the number of plasma cells and thus hypogammaglobulinemia. This congenital T-cell deficiency results from aberrant embryonic development of the third and fourth branchial arches, leading to hypoplasia of the thymus and parathyroid glands, as well as abnormalities ofthe mandible, ear, and aortic arch. Clinical manifestations include recurrent viral and fungal infections and tetany from hypoparathyroidism with hypocalcemia. Marked deficiency ofboth B and T cells manifests as profound lymphopenia and severe defects in both humoral and cell-mediated immunity. This syndrome occurs in both X-linked and autosomal variants; X-linked are more common. It is characterized by normal or elevated levels of IgM, but failure of isotype switching to IgG, 19A, or IgE. Homosexual or bisexual men (75% of cases) (1) the risk is apparently greater with anal receptive intercourse. Autoimmunity results in disease caused by immune reactions directed toward tissues of the host, with apparent inability to distinguish self from nonself. Examples include a number of autoimmune disorders, including autoimmune hemolytic anemia, Hashimoto thyroiditis, idiopathic adrenal atrophy, and a group of disorders referred to as connective tissue diseases. Host antigens may be recognized as nonself if modified by infection, infammation, or complexing with a drug. Infection (particularly viral) or other environmental agents may initiate autoimmune reactions in genetically susceptible individuals.

When this reaction is assessed by microscopic examination of cells using immunofuorescent techniques, a characteristic peripheral nuclear staining, or "rim" pattern, is seen. Serum complement is often greatly decreased, especially in association with active renal involvement. Hypertrophy of collagen fibers of the subcutaneous tissue, leading to tightening of the facial skin and a characteristic fixed facial appearance b. Visceral organ involvement, especially of the esophagus, gastrointestinal tract, kidneys, lungs, and heart (1) the esophagus is frequently affected, and dysphagia is common. This chronic inflammatory process especially involves the proximal muscles of the extremities. This minor salivary gland shows an intense lymphoid infiltrate, as well as destruction of the acini. This occurs mainly in women (80% of patients), with a peak incidence at 35 to 40 years of age. It is often manifest clinically by arthralgias, Raynaud phenomenon, esophageal hypomotility, and myositis. This immune complex vasculitis is characterized by segmental fibrinoid necrosis in the walls ofsmall and medium arteries of almost any organ. Drugs, such as sulfonamides and penicillin, may form immunogenic hapten-protein complexes. Symptoms and signs may include abdominal pain, hypertension, uremia, polyneuritis, allergic asthma, urticaria or rash, splenomegaly, fever, leukocytosis, and proteinuria. Amyloid is not a single substance but a group of substances that share a common physical structure that can be formed by a number of different proteins (Table 5-3). It always has a l-pleated sheet configuration (demonstrable by x-ray diffraction). It can also be demonstrated by a variety of other methods, including immunochemical, fluorescent, and metachromatic techniques. The cause is deposition of amyloid fibrils derived from immunoglobulin light chains. Usually, involvement of parenchymatous organs, especially the kidney (nephrotic syndrome is very common), liver. Secondary amyloidosis characteristically is a complication of chronic inflammatory disease. It also may complicate noninfammatory disorders, such as renal cell carcinoma and Hodgkin disease. Portuguesetype of polyneuropathy is associated with an amyloid derived from a protein known astransthyretin (a serum protein that transports thyroxine and retinol). Alzheimer disease is characterized by deposits of an amyloid protein referred to as A4 amyloid. The gene that codes for the protein precursors ofA4 amyloid has been localized to chromosome 21. The distribution and type of amyloid are similar to that of secondary amyloidosis (A amyloid). Diabetes mellitus in the insulin-resistant adult-onset form (type 2) is characterized by deposits of amyloid in islet cells. Senile amyloidosis is characterized by minor deposits of amyloid found at autopsy in the very elderly. Dialysis-associated amyloidosis is characterized by amyloid deposits in the joints of patients who have undergone hemodialysis for several years. The amylOid is derived from l-microglobulin, a protein not readily filtered by the dialysis membrane.

Which of the following referring to is a mutation in a gene coding is the best explanation for this findingfi A 2-year-old boy has eczema and red lesions, are observed in the skin of the thrombocytopenia. There is also a history face, upper trunk, and hands, and on the ofrecurrent infection. She has been troubled follows successful engrafment of a bone by small painful lumps under the skin of her marrow transplant. The basis of the clinical fingers, some ofwhich have ruptured and improvement is leaked a chalkywhite substance. She also (A) direct transfusion of antibody-producing complains ofpainful episodes in her fingers B cells. Telangiectatic (E) maturation of donor lymphoid clusters of vessels, appearing as small focal progenitor cells. The clinical description is characteristic of systemic anaphylaxs, an IgE-mediated type I hypersensitivity reaction. In type I hypersensitivty, reaction of antigen with preformed IgE antibodies fixed by Fc receptors to the surface of basophils or tissue mast cells results in cytolysis and degranulation of these cells, with release of histamine and other mediators. Failure of maturation of pre-B cells is associated with absence ofmature B lymphocytes and plasma cells; failure of antibody synthesis; marked serum hypogarmaglobulinemia; and recurrent bacterial infections, especially sinopulmonary infections. The disease is X-linked and is due to mutations in the B celltyrosine kinase (Btk) gene. The antigen-antibody-complement complexes are highly chemotactic for neutrophils, which release lysosomal enzymes and other mediators of tissue damage (prostaglandins, kinins, and free radicals). They may occur in any portion of the gene, even in intergenic regions ofthe genome, and are of increasing importance as genetic markers, as illustrated by the example presented here. This inherited B-cell defect is due to inability of19A B cells to mature into 19A-producing plasma cells. Interestingly, the defect leading to systemic anaphylaxis involves both 19A and IgE antibody formation. Patients lacking 19A can develop IgE antibodies against the 19A antibodies present in transfused blood. This sensitization can result in susceptibility to anaphylaxis on subsequent transfusion. Graft-versus-host disease is most often manifest by clinical findings related to the three principal target organs: the skin, liver, and gastrointestinal tract. Homozygotes are totally resistant, and heterozygotes develop a more slowly progressive disease. Death before 6 years of age occurs frequently and is most often due to bleeding, infection, or malignancy (most often lymphoma).
