Conversely, chronic rhinitis and air sacculitis can fulminate for many years with subtle clinical changes. The difficulty in distinguishing between clinical signs originating from the upper versus the 22 lower respiratory system makes the diagnosis and treatment of these problems challenging. Respira- tory health is best maintained by frequent exposure to fresh air and sunlight, a proper plane of nutrition and flighted exercise. Harrison ate subtle changes in posture, wing position, respira- tory rate and respiratory pattern that may indicate an abnormality. A bird uses its intercostal muscula- ture to expand and depress its chest, creating a “bel- lows” action that moves air into and out of the respi- ratory system. An increase in abdominal effort or head movement may be recognized in association with increased respira- tion following exercise, but should return to normal within minutes of ceasing exertional activity. Lung and lower respiratory tract problems are usually associated with a rhyth- mic jerking of the tail (tail-bob). A bird in severe respiratory distress may also move its head forward in an effort to increase air intake. If the respiratory problem is associated with excessive fluid produc- tion, bubbling and gurgling sounds are common on both inspiration and expiration (Table 22. Overt signs of respiratory disease are easy to identify and include oculonasal discharge, stained or matted feathers around the nares, sneezing, coughing, dysp- nea or audible inspirations or expirations (Figure 22. Changes in pitch or vocalization of the patient may indicate problems in the glottis, trachea or syr- inx.

Dyspnea around the nostrils, occluded nares, nasal discharge may also be caused by rhinoliths, air sac granulomas, or a growth or change in size of the nasal opening. With the efficiency of the air exchange Clinically important components of the avian respi- system in birds, it is unlikely that this procedure is ratory system include the external nares, operculum, of any value. The infraorbital sinus opens caudally into the cranial and cervical portions of the cervicocephalic air sac and dorsally into the middle nasal concha. By contrast, avian sinuses are restricted laterally by the skin and subcutaneous tissues of the face. The sinuses have simple mucous glands and are lined by stratified squamous and ciliated columnar epithelium. Hypovitaminosis A commonly causes squamous metaplasia and hyper- keratosis of the sinuses and nasal passages, leading to granuloma formation. Sinuses The infraorbital sinus is the only paranasal sinus in birds and is located lateral to the nasal cavity and surrounding the eyes ventrally. No other abnormalities were noted by physical examination, radiog- rous Passeriformes), the right and left infraorbital raphy or clinicopathologic evaluation.

In addition to an elimination diet, there are several other factors that can be helpful, such as ultraviolet light therapy, vitamin C, vitamin B12, ﬁsh oils, quercetin, and thyroid hormone. Ultraviolet Light Therapy Ultraviolet light (from sunlight or tanning beds) has been shown to be of some beneﬁt to patients with chronic hives. Patients with cold, cholinergic, and dermographic hives experience the greatest therapeutic response. Nutritional Supplements Vitamin C High-dose vitamin C therapy may help hives (as well as other allergic conditions) by lowering histamine levels. Vitamin B12 Although blood levels of vitamin B12 are normal in most patients with hives, additional B12 has been anecdotally reported to be of value in the treatment of acute and chronic hives. In one report, three patients with aspirin-induced urticaria experienced alleviation of symptoms following dietary supplementation with omega-3 fatty acids. Symptoms relapsed after the dose of ﬁsh oil was reduced, indicating that higher dosages may have to be maintained to keep symptoms from reappearing. Quercetin The ﬂavonoid quercetin inhibits both the manufacture and the release of histamine and other allergic/inﬂammatory mediators by mast cells and basophils. A subset of patients with chronic hives respond to thyroid hormone, especially if they have antibodies to thyroid tissue. Four patients with high thyroid antibody titers repeatedly experienced worsening when therapy was discontinued and had repeated remissions when therapy with L- thyroxine was resumed. Although L-thyroxine did not always improve the patient’s urticaria or angioedema, when it did work the response was dramatic. Acute hives is usually a self-limiting disease, especially once the eliciting agent has been removed or reduced. Diet An elimination diet is of utmost importance in the treatment of chronic hives (see the chapter “Food Allergy”). The diet should eliminate not only suspected allergens but also all food additives. Hyperthyroidism • Weakness, sweating, weight loss, nervousness, loose stools, heat intolerance, irritability, fatigue • Racing heartbeat; warm, thin, moist skin; stare; tremor • Diffuse enlargement of the thyroid, nonpainful goiter • Increased blood levels of thyroid hormones Hyperthyroidism is a condition characterized by increased levels of thyroid hormones: thyroxine (T4) and triiodothyronine (T3). The autoimmune disorder Graves’ disease accounts for up to 85% of all cases of hyperthyroidism. About 25 to 30% of people with Graves’ disease will also suffer from Graves’ ophthalmopathy (a protrusion of one or both eyes), in which the eye muscles become inflamed, attacking autoantibodies. In particular, it is eight times more common in women than in men and typically begins between the ages of 20 and 40. The classic clinical presentation of Graves’ disease is a young adult female complaining of nervousness, irritability, sweating, palpitations, insomnia, tremor, frequent bowel movements, and unexplained weight loss. Physical signs of hyperthyroidism include a smooth, diffuse, nontender goiter in the neck; a racing pulse, especially after exercise; loud heart sounds; and mild protrusion of the eyes with lid retraction. Other signs and symptoms include muscle weakness and fatigue, anxiety, heat intolerance, and ﬂuid retention. Pigment changes such as vitiligo (areas with loss of pigment) can be associated with Graves’ disease, as well as increased pigmentation of areas such as skin creases and the knuckles. Causes Stress One of the key causes of hyperthyroidism and/or Graves’ disease is recent stress. This association has been recognized as a precipitating factor ever since Graves’ disease was ﬁrst recognized. In fact, the most common precipitating event is an “actual or threatened separation from an individual upon whom the patient is emotionally dependent. Other causes of hyperthyroidism include early Hashimoto’s thyroiditis (see the chapter “Hypothyroidism”). Genetics People with certain types of genetic markers are statistically more prone to develop Graves’ disease, while people with other types of markers seem to be less frequently affected. In identical twins, if one twin is affected, the other has a 50% chance of manifesting the disease. In fraternal twins, if one twin is affected, the other has a 9% chance of having it as well. Smoking Smoking is known to raise the risk and severity of Graves’ ophthalmopathy. In one study, the effects of consuming iodized salt were studied in 267,330 inhabitants of Galicia. Also, iodine from other sources in doses above 600 mcg, such as potassium iodide, iodine supplements, medications such as amiodarone, and imaging contrast agents, can trigger Graves’ disease and toxic multinodular goiter. Advantages include the high rate of response and the fact that there is no need for ongoing suppression. Disadvantages include progression to hypothyroidism, elevated risk of nonlocalized cancers, and risk for parathyroid disease. We do not recommend surgery to remove the thyroid unless there are signiﬁcant extenuating circumstances. This drugs work by entering the thyroid and blocking the formation of thyroid hormones; speciﬁcally, they inhibit binding of iodine to tyrosine. In many parts of the world, including Europe and Japan, antithyroid drugs are the ﬁrst-line treatment for hyperthyroidism, as many cases of hyperthyroidism resolve spontaneously within 18 months. Naturopathic Care The chief objective of the natural treatment of Graves’ disease and hyperthyroidism is to reduce symptoms while trying to reestablish normal thyroid status. We recommend use of antithyroid drugs to reduce the immediate severity of hyperthyroid symptoms. Recommended dietary and lifestyle measures may lower the required dose or duration of antithyroid drugs, or raise the likelihood of disease remission with conventional treatment. Practical steps include reduction of risk factors (stress, smoking, excess iodine intake). Stress control is important in normalization of the thyroid, and counseling can prevent a return to stress- generating life strategies. Increase the amount of rest you get, including a nap after lunch and a full night’s sleep. Diet Patients with autoimmune thyroid disease, either Graves’ disease or Hashimoto’s thyroiditis (the major cause of low thyroid function), are more likely than the general population to suffer from celiac disease and/or gluten sensitivity. Also, identify food allergies and avoid problematic foods; see the chapter “Food Allergy. Keep in mind that the diet may need to be higher in calories to compensate for the increase in metabolism. We also recommend that you avoid caffeine and dietary sources of iodine (especially iodized salt, kelp and other seaweeds, seafood, and nutritional supplements that contain more than 300 mcg of iodine). Dietary Goitrogens Some foods contain goitrogens, substances that prevent the utilization of iodine.

Membrane sur- face polarity was modiﬁed by adding a positively charged polycation that adhered 224 P order 400mg levitra plus. Compared with older polyacrylonitrile membranes discount 400 mg levitra plus, this ensured highly selective endotoxin adsorption at its membrane sur- face [15 cheap 400 mg levitra plus overnight delivery, 65 buy 400mg levitra plus with amex, 66]. The adsorption of endotoxin is selective although the other components are not selectively adsorbed. Patients dialyzed with this membrane had less beta-2 microglobulin activity and a lower incidence of carpal tunnel syndrome . Membranes with an anionic component were found to clear substantial amounts of free immunoglobulin light chains [69 ]. This apparent immunomodulating effect might be useful as an adjunctive treatment in severe sepsis [68 , 69]. This was associated with improved hemodynamics, better oxygen transport, and reduced organ failure [63 , 70]. The adsorption of endoxin is performed through a selective mechanism whereas the adsorption of other components is unselective. Plasma samples of both patient groups were incubated with renal tubular cells and glomerular podocytes . This study targeted a population prone to high circulating endotoxin levels in which 17 Continuous Renal Replacement Therapy in Sepsis 225 the source control was obtained surgically . The Cytosorb car- tridge, for instance, contains 10 g of polystyrene divinylbenzene copolymer beads with a biocompatible polyvinylpyrrolidone coating. Each bead measures 300– 800 μm in size and each g of material has a surface of 850 m2 . Beads are slightly larger than a grain of salt, blood-compatible, porous, and highly adsorbent. This implies that most relevant pro- and anti-inﬂammatory cytokines can be removed from blood and physiologic ﬂuids. Substances entering the beads undergo hydro- phobic interactions with the neutral lipophilic surface of the polymer making them ﬁrmly adhere to the beads’ surface. Meanwhile, the large essential blood proteins can pass alongside the beads through the ﬁlter and back into the patient. The sole clinical investigation randomized 43 patients to receive standard treatment associated or not with Cytosorb therapy (provided 6 h daily, for 7 days) [78 ]. A major disadvantage of CytoSorb, however, is its inabil- ity to adsorb endotoxin . Awaiting more clinical trials, cytokine-adsorbing columns are actually applied as adjunctive therapy in conditions characterized by an ongoing hyperinﬂammatory 226 P. This is somewhat the same as for new membranes that are to be considered as potential adjunctive therapies in sepsis with also weak evidences so far [84 – 87 ]. Protein A, a major cell wall component of Staphylococcus aureus, binds human immunoglobulin (Ig) G with high afﬁnity. In Prosorba columns, protein A is covalently bound to a silica matrix and used to purify the patient’s plasma. Cells and plasma are separated with a continuous cell separator and 1,250 ml plasma passes through the column. This procedure was initially approved for treatment of idiopathic thrombocytopenic purpura. The mechanism underlying Prosorba-induced improvement in rheumatoid arthritis and sepsis is unknown. Additional factors, such as complement activation or produc- tion of anti-idiotype antibodies, likely do contribute to the observed clinical improvement . As for other sorbents and other related techniques, antimicrobial adsorption can be very high [92, 93] as described also for hyper-adsorptive membranes . High cut-off membranes can remove cytokines and are under evaluation for treatment of rhabdomyolysis and sepsis. Clinical evidence for the beneﬁt of adsorptive columns and selective plasma exchange is still scarce. More studies are deﬁnitely needed to identify the ideal membrane or sorbent for adjuvant treatment of sepsis.

Trisomy 21 (Down’s syndrome) is the most common chromosomal abnormality and is an important cause of mental retardation purchase levitra plus 400mg amex. Children with Down’s syndrome invariably have severe mental retardation cheap levitra plus 400 mg without a prescription, which pro- gressively declines with advancing age 400mg levitra plus overnight delivery. Patients have characteristic facial features that include a flat facial profile generic levitra plus 400mg, oblique palpebral fissures, and epi- canthal folds; a horizontal palmar crease; and a decreased muscle tone at birth that leads to a “floppy baby. There is also a marked increase in the incidence of acute leukemia, usually acute lymphoblastic leukemia, in children with Down’s syndrome who are younger than 3 years of age. There is almost a 100% incidence of Alzheimer’s disease in patients with Down’s syndrome 120 Pathology by the age of 35. Changes in the brains of patients with Down’s syndrome similar to those seen in the brains of patients with Alzheimer’s disease include senile plaques and neurofibrillary tangles. DiGeorge’s syndrome is associated with absence of the thymus, which leads to cell-mediated immune deficiencies, and absence of the parathyroids, which leads to hypocalcemia. The 5p− syndrome is also called the cri-du-chat syndrome, as affected infants characteristically have a high-pitched cry similar to that of a kitten. Additional findings in this disorder include severe mental retarda- tion, microcephaly, and congenital heart disease. Affected infants have many defects including micrognathia and a prominent forehead. The 11p− syndrome is characterized by the congenital absence of the iris (aniridia) and is often accompanied by Wilms tumor of the kidney. The 13q− syndrome is associ- ated with the loss of the Rb suppressor gene and the development of retinoblastoma. Deletions involving chromosome 15 (15q−) may result in either Prader-Willi syndrome or Angelman’s syndrome depending on whether the defect involves the paternal or the maternal chromosome (genetic imprinting). This finding is in sharp contrast to the classic concept of Mendelian inheritance, which states that the phenotype of a certain allele is independent of whether the chro- mosome is the maternal or the paternal chromosome. The best example of genetic imprinting involves deletions involving chromosome 15 (15q−). If the deletion involves the maternal chromosome, then Angelman’s syn- drome results, while deletions involving the paternal chromosome result in Prader-Willi syndrome. Angelman’s syndrome is characterized by severe mental retardation, seizures, a stiff ataxic gait with jerky movements, inap- propriate laughter, and occasional oculocutaneous albinism. Because of the combination of ataxic gait and inappropriate laughter, these patients are sometimes referred to as “happy puppets. The cause of genetic imprinting is not known, but it may relate to the degree of methylation of genes. Note that a loss of chro- mosome 15 can also occur if two parental chromosomes of the same type are derived from the same parent. This condition is called uniparental dis- omy, whereas the normal condition is called biparental disomy. Inheritance of the same (duplicated) chromosome is called isodisomy, while inheri- tance of homologues from the same parent is called heterodisomy. To illus- trate this concept, consider paternal uniparental disomy of chromosome 15. This refers to inheriting two copies of paternal chromosome 15 and no maternal chromosome 15. Therefore, this is essentially the same as a dele- tion of maternal chromosome 15, which produces Angelman’s syndrome. Inheriting two copies of paternal chromosome 11 results in Beckwith- Wiedemann syndrome. This is not a trisomy, as the maternal chromosome is lost, and therefore this would be a paternal uniparental disomy for chro- mosome 11. Patients also develop hypoglycemia because the genes for insulin and insulinlike growth factors are located in this region. Smith-Margens syndrome (17p−) is associated with self-destructive behav- ior, while Wolf-Hirschhorn syndrome (4p−) is characterized by growth retardation, severe hypotonia, and micrognathia. Characteristics of this syndrome include small stature due to a lack of a growth spurt during adolescence, a webbed neck, and multiple skeletal abnormalities that include a wide carrying angle of the arms where the elbow is out (cubitus valgus), a “shield-shaped” chest, and a high-arched palate. Individuals with Turner’s syndrome are phenotypic females, but they fail to develop secondary characteristics at puberty. Patients have streak gonads, histologic sections of which reveal atrophic, fibrous strands and are devoid of ova and follicles. These hypermaturing ovaries produce decreased estrogen levels, resulting in primary amenorrhea with no menar- che. About one-half of patients develop hypothyroidism due to autoanti- bodies against thyroid hormone. The relationship of the extra Y to behavior is controversial, but these individuals do have problems with motor and language develop- ment. Multi-X females are normal, except there is an increased tendency toward mental retardation that is proportional to the number of X chromo- somes that are present. Ductal sex depends on the presence of derivatives of the Müllerian or Wolffian ducts. True hermaphroditism refers to the presence of both ovarian and testicular tissue. Female pseudohermaphroditism results from excessive exposure General Pathology Answers 123 to androgens during early gestation; most often this is the result of con- genital adrenal hyperplasia. Male pseudohermaphroditism results from defective virilization of the male embryo, most commonly caused by com- plete androgen insensitivity syndrome, also called testicular feminization. Kallmann’s syndrome results from a lack of embryonic migration of cells from the olfactory bulb to the hypothalamus and is characterized by primary amenorrhea, lack of secondary sex characteristics, and decreased sense of smell (hyposmia). Mixed gonadal dysgenesis consists of one well-defined testis and a contralateral streak ovary. The first definable stage of B cell maturation occurs as the cell begins the process of producing immunoglobulin (Ig). The heavy chain genes, which are located on chromosome 14, are first rearranged, but because this occurs before the rearrangement of the light chain genes, complete immunoglobulin is not yet expressed on the cell surface. Instead µ heavy chain genes are rearranged first, and are found within the cytoplasm. If something goes wrong in this process, then the λ light chain genes on chromosome 22 are rearranged; otherwise they stay in their germline configuration. The synthesized light chains then combine with the intracytoplasmic µ heavy chains to form complete IgM, which is then transported to the surface, forming surface IgM (sIgM). Next these devel- oping B cells produce IgD, which is also expressed on the cell surface (sIgD). They 124 Pathology are also called “virgin” B cells because these cells have not encountered any foreign antigen. Before B cells become plasma cells, there may be a class switch (isotype switch) to a particular surface immunoglobulin that the plasma cell will then secrete. This activation occurs within germinal cen- ters, where morphologically B cells are classified as being small cleaved lymphocytes, large cleaved lymphocytes, small noncleaved lymphocytes (with prominent nucleoli), or large noncleaved lymphocytes (with promi- nent nucleoli). Prior to forming plasma cells, these activated B lymphocytes are called B immunoblasts.
