8 - Immunity: Defence Against Disease
The document discusses the human immune system, including both non-specific (innate) and specific (adaptive) immunity. Non-specific immunity involves physical and chemical barriers that provide a first line of defense against pathogens. If pathogens breach these barriers, white blood cells such as phagocytes, natural killer cells, and the complement system work to destroy invading microorganisms. Specific immunity involves B cells and T cells that can recognize specific pathogens and mount faster and stronger responses upon re-exposure through the production of antibodies and memory cells. The document also discusses immune system disorders like allergies, autoimmune diseases, and immunodeficiencies.

The document discusses the immune system and antibody-dependent cell-mediated cytotoxicity (ADCC). It describes how the immune system protects the body through identification, neutralization, and destruction of pathogens using cells like cytotoxic T lymphocytes, natural killer cells, and macrophages. It also explains that antibodies are proteins produced by B cells that bind to antigens, marking them for elimination. ADCC involves antibodies binding to target cells, cytotoxic cells attaching via Fc receptors on the antibodies, activation of the cytotoxic cells, and lysis of the target cell.
Innate Immune System
This document summarizes the innate immune system. It discusses the first line of defense which includes physical barriers like skin and mucous membranes. The second line of defense involves cells and proteins that attack pathogens if they breach the first line. Key cells of the innate immune system discussed are macrophages, neutrophils, natural killer cells, dendritic cells, monocytes, and phagocytes. Proteins of the innate immune system include complements and toll-like receptors.
10 - Innate Immunity
Innate immunity provides the first line of defense against pathogens and includes physical, chemical, and cellular barriers. Physical barriers include intact skin and mucous membranes. Chemical barriers include sebum, sweat, stomach acid, and antimicrobial substances. Cellular barriers are comprised of phagocytes that ingest and destroy pathogens. Additional innate immune responses include inflammation, fever, and antimicrobial substances released during infection. Together, these nonspecific defenses provide rapid protection against pathogens until the adaptive immune response can mount an antigen-specific response with memory.
Immunology overview
1. Dendritic cell eats bugs and displays antigens to naïve T cells using MHC class II. T cells mature.
2. Neutrophil eats and kills bugs with toxic chemicals. NK cell kills infected cells.
3. Helper T cell tells macrophage to eat bugs and tells B cell to make antibodies. Cytotoxic T cell finds and kills infected cells that display antigens using MHC class I.
4. B cell makes antibodies that coat bugs to neutralize and opsonize them, making them targets for macrophages.
11 - Adaptive Immunity
Adaptive immunity involves both humoral and cellular responses. B-cells produce antibodies that circulate in the blood and lymph to neutralize pathogens and toxins. T-cells recognize intracellular pathogens through antigen presentation and induce cytotoxic killing of infected cells. Antibodies and T-cells are activated through antigen recognition and work together to provide long-lasting adaptive immunity against specific pathogens. Vaccines utilize this immune memory to safely induce immunity against harmful diseases.

chest radiography: Collapse
This document discusses pulmonary collapse, also known as atelectasis. It defines collapse as a partial or complete loss of lung volume. Collapse can occur through different mechanisms such as relaxation, cicatrization, or adhesion. Common causes include endobronchial obstruction from tumors, infections, or foreign bodies. Radiographic signs of collapse include loss of aeration, fissure displacement, and compensatory hyperinflation. CT scans can reveal additional details like mucus plugging. The document reviews signs of collapse involving each lung lobe.
Apoptosis
Apoptosis is a natural and programmed form of cell death that occurs in multicellular organisms. It was first described in 1842 and distinguished from necrosis in 1965. During apoptosis, a series of biochemical events lead to changes in the cell and its death, allowing it to be eliminated in a controlled way that does not cause inflammation. This process is regulated by complex signaling pathways within the cell and involves mitochondria, caspases and other components. Defects in apoptosis can result in cancer if cell death is inhibited or neurodegenerative diseases if cell death is excessive.
Benign breast diseases
This document summarizes several benign breast diseases:
- Fibroadenoma is a common benign tumor in younger women that appears as a painless, smooth swelling. Fibroadenomas can be giant or multiple.
- Fibrocystic disease involves changes to breast tissue in response to hormones, causing painful swelling and nodularity, especially before menstruation.
- Sclerosing adenosis appears as a lump and involves proliferation of breast ducts and stroma.
- Mastitis can be lactational or non-lactational and causes breast pain, swelling and fever, usually treated with antibiotics.

IMMUNITY INTRODUCTION.ppt
The innate immune system provides the first line of defense against pathogens. It includes physical barriers like skin and mucous membranes, secretions containing antibodies, and immune cells like neutrophils, monocytes, macrophages, and natural killer cells that attack pathogens. When pathogens breach these defenses, internal responses are triggered, including cytokines that signal immune cells, complement proteins that coat pathogens, and coagulation factors that cause clotting. This activates inflammation, which causes swelling, redness, heat, and pain to isolate and destroy the pathogen. Together these innate responses provide rapid, non-specific protection against a wide range of microbes.

Chondrosarcoma is the second most common primary malignant bone tumor and often affects people over 40 years old. Giant cell tumor is a locally aggressive tumor characterized by sheets of mononuclear cells and multinucleated giant cells. Ewing's sarcoma is a small, blue, round cell tumor that commonly affects children and young adults under 20 years old.
Embolism & infarction 14 10-2016
Embolism occurs when a solid, liquid, or gaseous mass detaches and is carried by the bloodstream, potentially blocking blood vessels. The most common type is a thromboembolism from a dislodged blood clot. Infarctions result when an embolism blocks a vessel, cutting off blood flow and causing tissue death. Infarcts can be pale or red depending on the extent of bleeding. Factors like vascular supply and occlusion rate influence whether an infarction develops. Common embolisms include pulmonary embolisms from deep vein thromboses and arterial embolisms from heart sources. Resulting infarcts can occur in organs like the lungs, brain, and intestines.
Thrombosis 13 10-2016
Thrombosis results from an imbalance in the normal hemostatic system where there is inappropriate clot formation. It depends on contributions from Virchow's triad of endothelial injury, abnormal blood flow, and hypercoagulability. Endothelial damage or abnormalities in blood flow like stasis or turbulence allow clots to form. Hypercoagulable states like genetic mutations or inflammation also promote clotting. Thrombi may propagate and cause tissue injury, become organized, or embolize to distant sites. Disseminated intravascular coagulation is a consumptive coagulopathy where widespread microvascular thrombi activate fibrinolysis, initially causing thrombosis but potentially evolving into bleeding.
Non neoplastic bone diseases
1) Metabolic bone disorders include diseases associated with decreased bone mass such as osteoporosis, which is characterized by reduced bone mass and increased porosity of the skeleton.
2) Osteoporosis results from an accelerated loss of bone mass due to factors like aging, lack of physical activity, low estrogen levels, poor nutrition, and genetics.
3) Other diseases associated with abnormal bone include Paget's disease, which involves increased osteoclast resorption and osteoblast activity leading to deformed bones, and renal osteodystrophy in patients with chronic kidney disease.
Wound healing
1. Wound healing involves regeneration, which is the restoration of original tissue through cell proliferation, or repair through proliferation of connective tissue and scarring.
2. The process of wound healing involves inflammation, granulation tissue formation, collagen deposition and remodeling. Key cell types involved are macrophages, neutrophils and fibroblasts.
3. Factors like growth factors and cytokines regulate each step of wound healing, promoting processes like angiogenesis, collagen synthesis and wound contraction. Proper wound healing restores tissue structure and function.
Chronic inflammation
This document discusses chronic inflammation. It describes chronic inflammation as inflammation of prolonged duration involving ongoing inflammation, tissue injury, and attempts at repair. Chronic inflammation is characterized by mononuclear cell infiltration, tissue destruction, and attempts at healing through fibrosis and angiogenesis. Macrophages are a key player in chronic inflammation by secreting cytokines, growth factors, enzymes, and other inflammatory mediators that can cause both inflammatory tissue injury and repair. Granulomatous inflammation is a distinctive pattern of chronic inflammation seen in some infectious and noninfectious conditions, where macrophages form aggregates surrounded by lymphocytes called granulomas in an attempt to control difficult to eradicate agents.
Acute inflammation handouts 30 9-2016
Acute inflammation involves both vascular and cellular events. The vascular events include vasodilation of arterioles leading to hyperemia and increased permeability of post-capillary venules causing plasma protein exudation and edema. The cellular events involve neutrophil margination, rolling, adhesion, and transmigration into tissues followed by phagocytosis and clearance of pathogens. Key mediators include histamine, bradykinin, prostaglandins, leukotrienes, and cytokines which cause the vascular changes and recruit neutrophils.
Chronic inflammation 5 10-2016
This document discusses chronic inflammation. It describes chronic inflammation as inflammation of prolonged duration involving ongoing inflammation, tissue injury, and attempts at repair. Chronic inflammation is characterized by mononuclear cell infiltration, tissue destruction, and attempts at healing through fibrosis and angiogenesis. Macrophages are a key player in chronic inflammation by secreting cytokines, growth factors, enzymes, and other inflammatory mediators that drive both tissue injury and repair. Granulomatous inflammation is a distinctive pattern of chronic inflammation seen with certain infections and non-infectious conditions, where macrophages form aggregates surrounded by lymphocytes called granulomas in an attempt to control difficult to eradicate agents.
Intracellular accumulations and calcifications 22 9-2016
This document discusses pigmentations, calcifications, and intracellular accumulations. It defines pigments as colored substances that can be exogenous or endogenous. Exogenous pigments include carbon and tattoo ink. Endogenous pigments include lipofuscin (aging pigment), melanin, and hemosiderin. Lipofuscin is prominently seen in the liver and heart. Hemosiderin stains blue with Prussian blue stain. Calcifications can be dystrophic or metastatic. Dystrophic calcification occurs in dead tissue and is associated with necrosis, while metastatic calcification results from hypercalcemia. Dystrophic calcification is commonly seen in the heart valves and atherosclerotic arteries. Intracellular accumulations
Cell injury handouts 14 9-2016
Cellular injury can be reversible or irreversible, leading to cell death through necrosis or apoptosis. Reversible injury involves cellular swelling and changes that can be repaired, while irreversible injury destroys cell structures and function. ATP depletion disrupts sodium and calcium pumps, causing cellular swelling and damage from lysosomal enzymes and reactive oxygen species, leading to necrosis. Apoptosis is a genetically programmed form of cell death where caspases activate an intracellular death pathway, condensing and fragmenting the nucleus while keeping the plasma membrane intact.
Non neoplastic lesions of breast dr. mangala 14-9-2016
This document describes non-neoplastic lesions of the breast. It discusses the anatomy of the breast including lobes, lobules, ducts and sinuses. It then covers histology and the three normal phases of the breast. Several non-neoplastic lesions are described including fibrocystic change, inflammation such as mastitis and duct ectasia, and developmental abnormalities. Fibrocystic change is the most common proliferative condition and can cause periodic discomfort through cysts and fibrosis. Inflammatory conditions like mastitis typically present with pain and may lead to abscess.
Salivary gland tumors 23 5-2016
This document summarizes information about pleomorphic adenoma, the most common tumor of the parotid gland. It is a benign mixed tumor composed of epithelial and spindle-shaped cells in a myxoid stroma. On pathology it shows well-differentiated epithelial cells and spindle/stellate cells in an abundant mucoid matrix. Clinically it presents as a slow-growing, painless swelling of the parotid gland. The treatment is superficial parotidectomy to completely remove the tumor while preserving the facial nerve. There is a small risk of recurrence, particularly if the margins are positive, or of malignant transformation after many years.
Lung tumors 18 5-2016
Lung tumors can be carcinomas, bronchial carcinoids, or mesenchymal neoplasms. Lung cancer is the leading cause of cancer death worldwide, largely due to cigarette smoking. The risk increases based on amount smoked, inhalation, and duration of smoking. Occupational exposures like asbestos, radiation, and air pollution also increase risk. The major lung cancer types are squamous cell carcinoma, adenocarcinoma, small cell carcinoma, and large cell carcinoma. Squamous cell carcinoma is associated with smoking and keratinization. Adenocarcinoma occurs more in women and nonsmokers and shows glandular differentiation. Small cell carcinoma is very aggressive and metastatic.
Intrestitial lung disease 16 5-2016
1. The document discusses several cases of interstitial lung disease and pulmonary infection. Case 1 describes a man with nodularity and calcification found on chest x-ray, with biopsy revealing birefringent particles.
2. Case 2 involves a retired shipyard worker with shortness of breath and pleural plaques on CT, with dumbbell-shaped structures staining blue.
3. The document then reviews the etiology, pathogenesis, clinical features, patterns on imaging, and pathology of various forms of interstitial lung disease and pulmonary infections like bacterial pneumonia.
Intrestitial lung disease 9 5-2016
1. A 24-year-old woman presents with fever and enlarged hilar lymph nodes on chest X-ray. Her calcium level is elevated, suggesting the probable diagnosis of sarcoidosis.
2. A 37-year-old woman develops acute pneumonia symptoms and chest X-ray shows consolidation of her right lower lobe. Histology shows neutrophilic exudates in bronchioles and alveoli, consistent with bacterial pneumonia.
3. Bacterial pneumonia is usually caused by pathogens like Streptococcus pneumoniae and Haemophilus influenzae spreading via inhalation or aspiration due to impaired defenses. The patient's symptoms and radiological findings are consistent with a diagnosis of bacterial pneumonia.

1) The document discusses three lung conditions: atelectasis, ARDS, and interstitial pneumonia. It provides details on the causes, symptoms, diagnosis, and pathogenesis of each condition.
2) ARDS is characterized by diffuse pulmonary edema and hypoxemia. It develops due to acute lung injury from direct or indirect causes like sepsis, trauma, pneumonia, etc. There are three stages: exudative, proliferative, and fibrotic.
3) The pathogenesis of ARDS involves damage to lung endothelial and epithelial cells by cytokines and neutrophils, leading to accumulation of fluid in the lungs and impaired gas exchange. This results in hypoxemia and reduced lung compliance.
Copd 2 5-2016 madhu
COPD is a chronic obstructive lung disease characterized by obstruction of airflow from the lungs. It encompasses emphysema, chronic bronchitis, and asthma. Emphysema involves destruction of lung tissue and abnormal enlargement of airspaces, while chronic bronchitis is defined by a cough producing mucus for at least 3 months per year. Smoking is the leading cause of COPD and causes an imbalance between lung elastase and alpha-1 antitrypsin, damaging lung elastic tissue over time and leading to airflow obstruction. Symptoms include shortness of breath, chronic cough, wheezing, and increased susceptibility to infection.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
