The activated B cells are called as plasma cells and are responsible for secretion of antibodies. The allelic gene products were frst detected by their ability to stimulate lymphocyte proliferation by mixed lymphocyte reaction. It is present on all antigen presenting cells (B cells, dendritic cells and macrophages) and can be induced on endothelial cells and fbroblasts. Other important examples can be remembered from the mnemonic “My blood group is R h positive”. A positive result suggests the presence of antigen-nonspecifc immune complexes in the circulation. A positive raji cell assay that turns negative may suggest that the disease activity has improved. The immune complexes incite an activation of complement and produce infammatory reaction and necrosis. The initial target of these antibodies in rejection seems to be the graft vasculature. It can be due to: Patient who has already rejected a transplant Multiparous females Prior blood transfusions 61. Antigenic cross reactivity: this is due to similarity is the microbial antigenic structure and the self antigens.

Since, Raynaud’s phenomenon may the frst manifestation of these diseases, the patient with new symptoms need to be evaluated. Raynaud phenomenon, manifested as episodic vasoconstriction of the arteries and arterioles of the extremities, is seen in virtually all patients and precedes other symptoms in 70% of cases. The antigen-antibody complexes are detected by means of a fuorescein labeled anti-human immunoglobulin, and visualized with the aid of a fuorescence microscope”. So, any individual having the defciency of C1 esterase inhibitor would have excessive complement activation. This causes the release of anaphylatoxins (C3a, C5a) and other infammatory mediators. These patients therefore have episodes of edema affecting skin and mucosal surfaces such as the larynx and the gastrointestinal tract. This may result in life-threatening asphyxia or nausea, vomiting, and diarrhea after minor trauma or emotional stress. Patients have characteristic facies with broad nose, kyphoscoliosis, osteoporosis and eczema. Recurrent abscesses (known as cold abscesses) involving skin, lungs and other organs is a prominent feature Serum IgE level is signifcantly elevated whereas IgM, IgG and IgA level are normal.

Werner’s syndrome is a similar appearing disease that frst causes symptoms in affected individuals in their late teens. Tyrosine kinase (Ref: Robbins 8th/231-232, 9/e p240-241) This patient has X-linked (Bruton’s) agammaglobulinemiaQ, which is due to a defciency in a tyrosine kinaseQ, leading to a B cell maturation arrest at the pre-B cell level. The mother may experience an exacerbation in the activity of her disease in the third trimester or peripartum period. Conjunctivitis (Ref: Robbins 9/e p226-227, 8th/221) The patient has Sjögren’s syndrome, characterized by dry eyes (keratoconjunctivitis) and a dry mouth (xerostomia) due to destruction of the lacrimal and salivary glands. Cells similar to fbroblasts growing in a storiform (“pinwheel”) pattern (option A) are characteristic of dermatofbrosarcoma protuberansQ, a slow-growing type of fbrosarcoma. A sawtooth dermoepidermal junction (option C) is a feature of the skin condition lichen planus. Q Pautrier microabscesses (option D) are a feature of a cutaneous T-cell lymphoma called mycosis fungoides. The brain infection characteristically has a prominent perivascular character, which causes a multifocal hemorrhagic ne- crotizing meningoencephalitis. It is thought that the organ- isms may release a toxin causing host tissue necrosis. Naegleria fowleri (choice D) is an amoebic cause of meningoencephalitis in previously healthy swimmersQ and divers. The tumor has an appearance very similar to that of angiosarcomaQ-proliferating stromal cells and endothelium creating vascular channels that contain blood cells. The patients with the disease are prone to the development of persistent diarrhea caused by G. Central penicilliary arteries may show concentric intimal and smooth muscle cell hyperplasia, producing so- called onion-skin lesionsQ. The follicles are depleted of cells, and the organized network of follicular dendritic cells is disrupted. The antibodies may be present in the infant because of maternal infection also because IgG antibodies can cross the placental barrier. By comparison, the female-to-male ratio is only 2:1 for disease developing during childhood or after the age of 65. Deposition of the amyloid in long term hemodialysis takes place in joints and in the carpal ligament of the wrist, the latter leading to development of ‘carpal tunnel syndrome’ 124. The sites for the biopsy can be the renal tissue, rectum, abdominal fat aspiration and gingiva. If it is found to be negative, more invasive biopsy of other affected organ can be taken. A mutant form of transthyretin is deposited in a group of genetically determined disorders referred to as familial amyloid polyneu- ropathies’. It is similar to the normal b2 microglobulin protein which is retained in circulation of patients with renal failure because it cannot be fltered through the cuprophane dialysis membrane. Several studies have clearly demonstrated that blockade of smooth muscle cell proliferation resulted in preservation of normal vessel pheno- type and function, causing the reduction of neointimal hyperplasia and graft failure. This interleukin activates both T and B-lymphocytes but does not activate macrophages.
Note: It differs from dermatomyositis by the absence of rash (no cutaneous involvement) and its occurrence mainly in the elderly purchase himcolin american express erectile dysfunction treatment cialis. In another infammatory myopathy called inclusion body myositis purchase himcolin us erectile dysfunction after radiation treatment for prostate cancer, there is presence of endomysial infammation himcolin 30gm sale erectile dysfunction 35, basophilic granular deposits around the edge of slit-like vacuoles (rimmed vacuoles) and loss of fbers (being replaced with fat cells and connective tissue). There is characteristically presence of β amyloid deposits and cytochrome oxygenase negative fbers are seen. Rheumatoid factor, an IgM antibody directed against the Fc portion of IgG, is found in about 80% of affected individuals. The bulk of the tumor consists of non-neoplastic osteoclasts and their precursors. The earliest involved joints are typically the small joints of the hands and feet. As the book mentions; most frst attacks are monoarticular; 50% occur in the frst metatarsophalangeal joint. First of all, read both assertion (A) and reason (R) carefully and independently analyse whether they are true or false. If both A and R are ture, then we have to know whether R is correctly explaining A [answer is (a)] or it is not the explanation of assertion [answer is (b)] 1. This is attributed to the absence of the skeletal muscle contractile protein dystrophin in these patients. Altered dystrophin is responsible for muscular weakness in patients of Becker’s muscular dystrophy. The likelihood of a salivary gland tumor being malignant is inversely proportional to the size of the gland which means the tumors in minor salivary glands are more likely to be malignant and those in parotid are mostly benign. These tumors usually occur in adults, with a slight female predominance except Warthin tumor which occur more often in males than in females. Pleomorphic Adenoma or Mixed Tumors • They are the most common benign tumors that are derived from a mixture of ductal (epithelial) and myoepithelial cells, and therefore they show both epithelial and mesenchymal differentiation. Most pleomorphic adenomas present as rounded, well-demarcated masses rarely exceeding 6 cm. The incidence of malignant transformation increases with the duration of the tumor. Warthins Tumor (Papillary Cystadenoma Lymphomatosum) • It is the second most common benign salivary gland neoplasm. It arises almost always in the parotid gland and occurs more commonly in males than in females, usually in the ffth to seventh decades of life. The double layer of lining cells is distinctive, with a surface palisade of columnar cells having an abundant, fnely granular, eosinophilic cytoplasm, imparting an oncocytic appearance, resting on a layer of cuboidal to polygonal cells. Mucoepidermoid carcinomas can grow up to 8 cm in diameter, lack well-defned capsules and are often infltrative at the margins. The basic histologic pattern is that of cords, sheets, or cystic confgurations of squamous, mucous, or intermediate cells. The hybrid cell types often have squamous features, with small to large mucus-flled vacuoles, best seen with mucin stains. Two other salivary gland tumors include: Adenoid cystic carcinoma and acinic cell tumor. In 50% of cases, it is found in the mi- nor salivary glands (in particular; the palate). They have high chances of recurrence and eventually, 50% or more disseminate widely to distant sites such as bone, liver, and brain. The acinic cell tumor is composed of cells resembling the normal serous acinar cells of salivary glands. Most arise in the parotidsand the small remainder arises in the submandibular glands. Most characteristically, the cells have apparently clear cytoplasm, but the cells are sometimes solid or at other times vacuolated. The cells are disposed in sheets or microcystic, glandular, follicular, or papillary patterns. On histologic evaluation, they are composed of small cells having dark, compact nuclei and scant cytoplasm. The spaces between the tumor cells are often flled with a hyaline material thought to represent excess basement membrane. Neuroblastoma It is the most common extracranial solid tumor of childhood and the most frequently diagnosed tumor of infancy. There are two clinical types, based on the differences in distribution of metastasis. First (Pepper type) occurs in the stillborn and in young infants and metastasizes to the liver and regional lymph nodes, then the lungs, and late in the course, the calvarium and other fat bones. The second (Hutchinson) type is characterized clinically by secondary growth in the orbit, meninges, skull and long bones and occurs in childrenup to 15 years of age. It shows central space flled with eosinophilic fbrillary material called neuropil surrounded by concentrically arranged tumor cells (Homer-Wright pseudorosettes). Presence of Schwannian stroma, mature Schwann cells and fbroblasts is a histologic pre- requisite for the designation of ganglioneuroblastoma and ganglioneuroma. It signifes localized primary tumor with dissemination limited to skin, liver and/or bone marrow. Histology Schwannian stroma Present Absent Gangliocytic differentiation Present Absent Mitotic rate Low High Mitotic karyorrhexis index <200/5000 cells (≤ 4%) >200/5000 (> 4%) Intramural calcifcation Present Absent 4. Retinoblastoma • Retinoblastoma is the most common malignant eye tumor of childhood. Hereditary retinoblastoma when affecting both eyes is called bilateral retinoblastoma. The nuclei are displaced away from the lumen and photoreceptor like elements are produced from it. Retinoblastoma also shows Homer Wright rosettes which are radial arrangement of cells around a central tangle of fbrils. The risk of Wilms’s tumor is increased in association with at least three recognizable groups of congenital malformations: 1. Denys-Drash syndrome, which is characterized by gonadal dysgenesis (male pseudo- hermaphroditism) and early-onset nephropathy leading to renal failure. The charac- teristic glomerular lesion in these patients is a diffuse mesangial sclerosis. In addition to Wilms’ tumors, 651651 Review of Pathology these individuals are also at increased risk for developing germ-cell tumors called gonadoblastomas. Beckwith-Wiedemann syndrome, characterized by enlargement of body organs (organomegaly), macroglossia, hemihypertrophy, omphalocele, and abnormal large cells in adrenal cortex (adrenal cytomegaly). In addition to Wilms’ tumors, patients with Beckwith-Wiedemann syndrome are also at increased risk for developing hepatoblastoma, adrenocortical tumors, rhabdomyosarcomas, and pancreatic tumors. Morphology Grossly, Wilms’s tumor tends to present as a large, solitary, well-circumscribed mass and on cut section, the tumor is soft, homogeneous, and tan to grey with occasional foci of hemorrhage, cyst formation, and necrosis. Microscopically, Wilms’s tumors are characterized by the classic triphasic combination of blastemal, stromal, and epithelial cell types observed in the vast majority of lesions. Pulmonary Langerhans’ cell histiocytosis: most often seen in adult smokers and can regress spontaneously on cessation of smoking.
In addition 30gm himcolin sale cheap erectile dysfunction pills online uk, glucocorticoids are important in the differentiation of preadipocytes to adipocytes cheap himcolin 30gm fast delivery erectile dysfunction drugs recreational use, a process termed adipogenesis order 30gm himcolin with mastercard impotence 25 years old. In patients with Cushing syndrome, elevated blood glucocorticoid levels cause excess fat deposition in the abdomen surrounding the organs (visceral obesity), insulin resistance, dyslipidemia, and hypertension. A similar collection of metabolic abnormalities is present in obese people, which has prompted investigation into the possibility that general obesity could be attributed to glucocorticoid excess. Although subtle alterations in the hypothalamic–pituitary–adrenal axis have been observed in obesity, no clear role for increased circulating glucocorticoid has been established. Until recently, tissue glucocorticoid concentrations were thought to be determined by the level of glucocorticoid in the blood and tissue responses controlled by the availability of glucocorticoid receptors. Its main role is in aldosterone-sensitive target tissues such as the kidney, colon, salivary glands, and placenta. Cortisol circulates in the blood at concentrations severalfold higher than those of aldosterone, but both hormones have an affinity for the nonselective mineralocorticoid receptor. The cortex contains three histologically distinct zones (from outside to inside): the zona glomerulosa, zona fasciculata, and zona reticularis. Hormones secreted by the adrenal cortex include glucocorticoids, aldosterone, and adrenal androgens. The glucocorticoids cortisol and corticosterone are synthesized in the zona fasciculata and zona reticularis of the adrenal cortex. The mineralocorticoid aldosterone is synthesized in the zona glomerulosa of the adrenal cortex. Cholesterol, used in the synthesis of the adrenal cortical hormones, comes from cholesterol esters stored in the cells. Stored cholesterol is derived mainly from low-density lipoprotein particles circulating in the blood, but it can also be synthesized de novo from acetate within the adrenal gland. The conversion of cholesterol to pregnenolone in mitochondria is the common first step in the synthesis of all adrenal steroids and occurs in all three zones of the cortex. The liver is the main site for the metabolism of adrenal steroids, which are conjugated to glucuronic acid and excreted in the urine. Glucocorticoids are essential to the adaptation of the body to fasting, injury, and stress. The chromaffin cells of the adrenal medulla synthesize and secrete the catecholamines epinephrine and norepinephrine. Catecholamines interact with four adrenergic receptors (α, α, β, and β ) that mediate the1 2 1 2 cellular effects of the hormones. Stimuli such as injury, anger, pain, cold, strenuous exercise, hypoglycemia, and psychological stress generate impulses in the cholinergic preganglionic fibers innervating the chromaffin cells, resulting in the secretion of catecholamines. To counteract hypoglycemia, catecholamines stimulate glucose production in the liver, lactate release from muscle, and lipolysis in adipose tissue. Which of the following sources of cholesterol is most important for sustaining adrenal steroidogenesis when it occurs at a high rate for a long time? Cholesterol in lipid droplets within adrenal medullary cells The correct answer is B. De novo synthesis of cholesterol from acetate is a minor source of cholesterol in humans. Cholesterol from the plasma membrane or endoplasmic reticulum is not used for steroidogenesis. Cholesterol esters in lipid droplets within adrenal cortical cells would be used first and depleted during periods of high adrenal steroid hormone synthesis. A 7-year-old boy comes to the pediatric endocrine unit for evaluation of excess body weight. Review of his growth charts indicates substantial weight gain over the previous 3 years but little increase in height. To differentiate between the development of obesity and Cushing syndrome, blood and urine samples are taken. The increase in body weight with little linear growth suggests that the patient has Cushing disease rather than general obesity since linear growth usually continues in obesity syndromes. Congenital adrenal hyperplasia is the result of genetic defects that affect adrenal steroidogenic enzymes resulting in impaired formation of cortisol. Addison disease is the result of pathologic destruction of the adrenal glands by microorganisms or autoimmune disease and would therefore not result in adrenal hyperplasia. Corticosteroid-binding globulin noncovalently binds steroid hormones in plasma; defects in this protein are not associated with adrenal hyperplasia. What is the mechanism through which catecholamines stabilize blood glucose concentration in response to hypoglycemia? Catecholamines stimulate glycogenolysis and gluconeogenesis in the liver, causing glucose to be synthesized and released into the blood. Catecholamines stimulate glycogen phosphorylase in muscle to free glucose for use by the muscle. Muscle cannot release glucose to the circulation because it lacks glucose-6-phosphatase. However, the muscle can release lactate, which can be used in gluconeogenesis by the liver. Catecholamines increase the release of fatty acids from the adipose tissue, to be used in gluconeogenesis by the liver. A patient receiving long-term glucocorticoid therapy plans to undergo hip replacement surgery. Glucocorticoids should be decreased to prevent serious hypoglycemia during recovery. Glucocorticoids should be increased to stimulate immune function and prevent possible infection. Glucocorticoids should be decreased to minimize potential interactions with anesthetics. Glucocorticoids should be decreased to prevent inadequate vascular response to catecholamines during recovery. Glucocorticoids should be increased to compensate for the increased stress associated with surgery. Patients on long-term glucocorticoid therapy should have the dose increased prior to undergoing surgery to minimize the effects of surgical stress. These patients cannot mount their own stress response because of the lack of adrenal cortisol release. Glucocorticoid-induced hypoglycemia or interactions with anesthetics are not likely, and these concerns would be secondary to stimulating the response to surgical stress. The baby was born at home and is now being seen in the emergency room because she appears listless and has not nursed at all during the last 24 hours. The parents report that the baby has become increasing listless and less willing to nurse since birth. Upon physical examination, the baby exhibits signs of virilization (growth of pubic hair) and hyponatremia (low plasma sodium), hyperkalemia (high plasma potassium), and volume depletion. Based on the physical examination, history, and what you know about adrenal steroidogenesis, what would be a reasonable initial hypothesis? What are the two most likely congenital defects in adrenal steroidogenic enzymes that could explain the findings in this child?
