Schistosomiasis It is the most important helmenthic disease infecting 200 million people & killing 250 buy 10mg lexapro otc anxiety 40 year old woman,000 annually order lexapro with a mastercard anxiety jacket for dogs. Ghycocalyx that protect the organism from osmotic is shed but it activates complement by alternative pathway discount lexapro 10mg overnight delivery health anxiety symptoms 247. Schistosoms migrate into peripheral vasculature transverse to the lung and little in the portal venous system where they develop into adult male and female schistosomes order lexapro 20mg online anxiety symptoms losing weight. Females produce hundreds of eggs per day around which granulmas and fibrosis form the major manifestation in schistosomiasis. Some schist some eggs are passed from the portal veins through the intestinal wall into the colonic lumen are shed with the feces and released into fresh water, form to miracidia that infect the snail to complete the life cycle. Resistance to reinfection by schistosomes after treatment correlates with IgE levels whereas, eosinophile major basic proteins may destroy larvae schistsomula. Eggs release factors that stimulate lymphocytes to secrete a lymphokine that stimulate fibroblast proliferation and portal fibrosis the exuberant fibrosis which is out of proportion to the injury caused by the eggs and granucoma, occurs in 5% of persons infected with schistosomes and cause severe portal hypertension esophageal varicoses and ascites the hallmark of severe schistosomiasis. The liver is darken by regurgitated pigments from the schistosome gut which like malaria pigment are iron negative and accumulate in kuffer cells and splenic macrophages. Japanicum) Colonic pseudopolyps Liver surface is bumpy and its cut section shows granuloma and wide spreading fibrous portal enlargement without distortion of the intervening parenchyma. Schistome eggs diverted to the lungs through portal collateral may produce granulomatous pulmonary arteritis with intimal hyperplasia progressive arterial obstruction and ultimately heart failure (cor pulmonale). Patients with hepatosplenic Schistosomiasis have also increased frequency of mesangioproliferative glomerulonephritis or membranous glomerulonepritis in which 182 glomeruli contain deposits of immunoglobulins and compliments but rarely schstosomal antigens. Latter the granuomas calcify and develop a sandy appearance and in severe cases, it causes concentric rim on the wall of the bladder forming calcified bladder on x rays films. When the urinary inflammation involves the ureteral orifices, it causes obstructive hydronephrosis and chronic pylonehphritis. Urinary schistosomiasis is also associated with squamous cell carcinoma of the bladder that is commonly seen in Egypt. Fungal Infections There are 100,000 known fungi and only few infect humans mostly opportunistically. Only few are involved in human diseases because most fungi are destroyed by cell-mediated immune responses however, humoral immunity plays little or no role. Predisposing factors for fungal infections include: Corticosteroid administration, acquired or congenital immunodeficiency states, defects in neutrophillic and macrophage functions Fungal infections are divided into superficial and deep fungal infections (mycosis). Candidiasis (Moniliasis) Normally found in mouth, skin and gastrointestinal tracts. It affects locally the skin, nail and mucous membranes and it grows best in warm, moist surface and cause vaginitis, diaper rash & oral trush. Morphology: • Oral trush & vaginitis are superficial lesions characterized by white patches (or fluffy membrane) • Cutaneous eczematous lesion: Seen in moist area such as between fingers, & toes and in inguinal areas, inflamammary folds and ano-genital regions. These lesions may contain acute and chronic inflammations with micro abscesses but in their chronic states granulomatous inflammations may develop. Many organs may be involved for examples include kidney with micro abscesses in 90%, and right side candidal endocarditis. Pathogenesis: Found in soil and droppings of birds (peogons): Three factors associated with virulence 1) Capsular polysaccharides 2) Resistant to killing by alveolar macrophages 3) Production of phenol oxidase, which consumes host epinephrine oxidase system. This enzyme consumes host epinephrines in the synthesis of fungal melanin thus, preventing the fungus from epinephrine oxidase system C. Morphology: Lung is the primary site of localization with minor or asymptomatic presentation; here solitary granulomatous lesions may appear. In immunosupressed patients, the organisms may evoke no inflammatory reactions so; gelatinous masses of fungi grow in the meninges or in small cysts within the grey matter (soap bubble lesion) 3.

Metastatic cancers (leukaemia order generic lexapro on-line anxiety symptoms rash, lymphoma and adenocarcinoma) generic lexapro 10mg otc anxiety breathing, medulloblastomas, and ependymomas shed the greatest amount of material. Though meningioma occurs in the subarachnoid space, it rarely exfoliates sufficient material for diagnosis. There are large number of malignant cells scattered grade gliomas may yield adequate cellular material for singly or in small clusters having characteristic cytoplasmic vacuoles, diagnosis. Epithelial cells of mesothelioma require to be Examination of seminal fluid (semen analysis) is one of the distinguished from adenocarcinoma cells. They mostly represent masturbation or coitus interruptus after observing at least 4 metastasis from primary adenocarcinomas such as from the days of sexual abstinence and assessed on the following lines: stomach, lung, breast, colon, and ovary. Less frequent sources are adenocarcinoma of the biliary system, pancreas and liver. When ejaculated, semen is fairly viscid appearance and thus it may not be possible to comment on but liquefies in about 10 to 30 minutes. It is usually alkaline the possible primary site of origin of the adenocarcinoma on (pH about 8). Effusion may rarely have 60% of the spermatozoa are vigorously motile; in 6 to 8 hours malignant squamous cells in it and represent metastasis from 25 to 40% are still motile. Normally, 60 million or more spermatozoa carcinoma of the lung are quite characteristic—hyper are present per ml. Currently, automated counters for semen chromatic moulded nuclei and scanty or no cytoplasm. Stained smears are used to assess malignant cells of leukameia and lymphoma in line with morphology. Seminal fructose estimation (normal levels 150 Of the miscellaneous fluids included in this category, the 600 mg/dl) complements cytological analysis. Samples are usually obtained Even specimens with several abnormal features need not by lumbar puncture. Factors that are critical to the successful necessarily be the cause of infertility. The number of Barr 275 bodies observed in interphase nuclei is one less than the number of X chromosome (n–1), whereas the number of F bodies observed is equal to the number of Y chromosomes present (n). In effect, the Barr body is specific for females and the F body for males (page 257). In buccal smears, the Barr body appears as a plano convex mass about 1 μm in diameter applied to the inner surface of the nuclear membrane. The interphase nuclei of one hundred intermediate squamous epithelial cells are scrutinised. Demonstration of the F body requires fluorescent presence of drumstick appendage attached to a nuclear lobe of the staining in contrast to the Barr body which may be observed neutrophil. On staining buccal smears with quinacrine mustard, the intensely fluorescent F iv) the ectocervix is sampled with the Ayre’s spatula body is observed in about 60% of interphase nuclei in males. The longer limb of the spatula is fitted into the and in less than 8% of nuclei in females. The F body is also external os and the spatula rotated through 360° to sample demonstrable in the nuclei of lymphocytes in a peripheral the entire cervix. The scraped material on the spatula is then blood film stained with quinacrine mustard. The smear prepared with the spatula itself or with the tip of the presence and frequency of drumstick appendages attached gloved finger (cotton swabs may be used instead of the Ayre’s spatula, although the quality of smears is not as good).

Reference Ranges For some common analytes the reference ranges are similar throughout Australia (e. For hormones and other tests where methodology can vary from one laboratory to another, the reference ranges can differ quite markedly. Even in the same laboratory, ranges may change from time to time as new methods are introduced. A reference range can be defned as a range derived from measuring an analyte in a reference population using a reference method. In clinical practice, a patient’s results can be examined in different ways, either by comparison to a reference interval, by comparison to their own known previous values, or by consideration of desirable goals, e. Some useful ranges are not reference ranges at all, but rather therapeutic ranges, e. At Capital Pathology, specialist pathologists are not only responsible for management decisions, but are intimately involved in all clinical and ethical matters. Our pathologists pride themselves on their close clinical relationship with our referring doctors, and they recognise the importance of providing a comprehensive consultative and educational service. This is exemplifed on a day-to-day basis by an expanding range of interpretive comments on reports. In order to optimise patient care, we understand the importance of discussion with clinicians through phone calls as well as providing advice and feedback at personal visits. Capital Pathology’s specialist pathologists have a long history of commitment to continuing education for family doctors and specialists through educational seminars and regular newsletters. Even more importantly, the continual guidance provided by our pathologists determines the quality and integrity of our whole service. Although our practice obviously must remain commercially viable, the medical infuence provided by our pathologists ensures that purely commercial considerations never take precedence over ethical and professional standards.
