It requires correlations between normal and abnormal anatomy and physiology as well as the processes resulting in the manifestations of disease. This Study Guide is designed for students as an adjunct to Understanding Pathophysiology, fifth edition, by Sue E. Huether and Kathryn L. McCance. It is intended to facilitate an understanding of the consequences of pathologic proc- esses on the structure and function of the human body. The Study Guide contains 40 chapters, each following the organization of the textbook. The Guide’s chapters have two different formats—one for normal anatomy and physiology and another for anatomic and physiologic alterations. For the normal anatomy and physiology chapters, it is assumed that the student possesses foundational knowledge of anatomy and physiology; therefore, no supplemental narrative is provided. n These chapters have foundational objectives that direct review of the information, principles, and concepts that are essential for understanding the specific diseases that follow in the next chapter. Chapters five and six depart from the usual normal anatomy and physiology chapter’s format. This departure is because inflammation and immunity con- cepts are frequently referenced throughout the following text and study guide chapters. n Each chapter has a practice examination to give students an opportunity to assess their understanding of normality. The chapters on alterations direct the learner’s study of abnormal anatomy and physiology. n These chapters include 1) foundational objectives for review and 2) learning objectives for study with narrative, charts, and tables. n Each chapter has a practice examination requiring factual and conceptual knowledge related to disease mechanisms. n Each chapter includes one or two case studies linking fact and concept to reality that require analysis and applica- tion. The objectives for all chapters are referenced to corresponding pages in the fifth edition of Understanding Pathophysiology. Huether and McCance’s philosophy that students need to grasp basic laws and principles to understand how alterations occur led them to develop an understandable and conceptually integrated textbook. I enjoyed working with Mosby, particularly with Charlene Kechum and Jeanne Genz. All of Mosby’s staff ensured that my efforts were developed into a creative, professional, and pleasing style for student learners. I wish to dedicate my efforts during the preparation of this Study Guide to students who inspired me to search for a better way to convey information to them. Clayton F.

[email protected] Abstract Dermatomyositis is an idiopathic inflammatory myopathy with characteristic cutaneous manifestations. We describe a case of a 55- year-old woman with dermatomyositis who presented with dystrophic calcinosis resistant to medical treatment. Dermatomyositis is an idiopathic inflammatory myopathy with characteristic cutaneous manifestations, including heliotrope rash, Gottron papules, periungual telangiectasias, photodistributed erythema, poikiloderma, and alopecia. Although heliotrope rash and Gottron papules are specific cutaneous features, calcinosis of the skin or muscles is unusual in adults with dermatomyositis. However, it may occur in up to 40 percent of children or adolescents [1]. Calcinosis cutis is the deposition of insoluble calcium salts in the skin. Calcinosis cutis may be divided into four categories according to the pathogenesis as follows: dystrophic, metastatic, idiopathic, and iatrogenic. In connective tissue diseases, calcinosis is mostly of the dystrophic type and it seems to be a localized process rather than an imbalance of calcium homeostasis. Calcium deposits may be intracutaneous, subcutaneous, fascial, or intramuscular. Clinical synopsis A 55-year-old woman was referred for evaluation because of multiple, firm nodules of the lateral hips since 1994. At that time, dermatomyositis was diagnosed based on cutaneous, muscular and pulmonary involvement. The nodules, gradually enlarging since 1999, have begun to cause incapacitation pain and many exude a yellowish material suggestive of calcium. She denied an inciting traumatic event.

Secundum ASD © 2015 Published by Elsevier Masson SAS on behalf of the Éditions françaises de radiologie. Introduction Major technical advances in computed tomography (CT) in recent years have made it pos- sible to use multidetector row CT (MDCT) in the field of cardiac imaging. Besides coronary arteries, ECG-gated cardiac MDCT provides high-resolution images of all cardiac structures. It is therefore important for radiologists to understand and be able to analyze the normal anatomical structures, variants and diseases of these different structures. This article provides an analysis of the interatrial septum (IAS) based on a pictorial review. After a short embryological and anatomical description, we will illustrate the nor- mal anatomy and variants of the IAS, anomalies such as patent foramen ovale (PFO), congenital diseases such as atrial septal defects (ASD) as well as tumors and tumoral-like processes that develop on the IAS. Abbreviations: ASA, atrial septal aneurysm; ASD, atrial septal defect; ECG, electrocardiogram; IAS, interatrial septum; IVC, inferior vena cava; IVS, interventricular septum; LV, left ventricle; M, myxoma; PFO, patent foramen ovale; RSPV, right superior pulmonary vein; RV, right ventricle; SVC, superior vena cava; MIP, maximal intensity projection; TEE, transesophageal echocardiography; TV, tricuspid valve.

  • Eye Neoplasm
    Eye neoplasm Origin and location Eye cancers can be primary (starts within the eye) and metastatic cancer (spread to the eye from another organ). The two most common cancers that spread to the eye from another organ are breast cancer and lung cancer. Other less common sites of origin include the prostate, kidney, thyroid, skin, colon and blood or bone marrow. Types Tumors in the eye and orbit can be benign like dermoid cysts, or malignant like rhabdomyosarcoma and retinoblastoma. Signs and symptoms • Melanomas (choroidal, ciliary body and uveal) - In the early stages there may be no symptoms (the person does not know there is a tumor until an ophthalmologist or optometrist looks into the eye with an ophthalmoscope during a routine test). As the tumor grows, symptoms can be blurred vision, decreased vision, double vision, eventual vision loss and if they continue to grow the tumor can break past the retina causing retinal detachment. Sometimes the tumor can be visible through the pupil. • Nevus - Are benign, freckle in the eye. These should be checked out and regular checks on the eye done to ensure it hasn't turned into a melanoma. • Iris and conjuctival tumors (melanomas) - Presents as a dark spot. Any spot which continues to grow on the iris and the conjunctiva should be checked out. • Retinoblastoma - Strabismus (crossed eyes), a whitish or yellowish glow through the pupil, decreasing/loss of vision, sometimes the eye may be red and painful. Retinoblastoma can occur in one or both eyes. This tumor occurs in babies and young children. It is called RB for short.

  • T PATHOLOGIC CALCIFICATION Deposition of Calcium Salts In
    t PATHOLOGIC CALCIFICATION Deposition of calcium salts in tissues other than osteoid or enamel is called pathologic or heterotopic calcification. Two distinct types of pathologic calcification are recognised: Dystrophic calcification, which is characterised by deposition of calcium salts in dead or degenerated tissues with normal calcium metabolism and normal serum calcium levels. Dystrophic calcification may occur due to 2 types of causes: ● Calcification in dead tissue ● Calcification of degenerated tissue Metastatic calcification, on the other hand, occurs in apparently normal tissues and is associated with deranged calcium metabolism and hypercalcaemia. Since metastatic calcification occurs in normal tissues due to hypercalcaemia, its causes would include one of the following two conditions: ● Excessive mobilisation of calcium from the bone. ● Excessive absorption of calcium from the gut. Pathogenesis of Dystrophic Calcification The process of dystrophic calcification has been likened to the formation of normal hydroxyapatite in the bone involving 2 phases: ● Initiation and propagation: Initiation is the phase in which precipitates of calcium phosphate begin to accumulate ​ intracellularly in the mitochondria, or extracellularly in membrane-bound vesicles. Propagation is the phase in which minerals deposited in the initiation phase are propagated to ​ form mineral crystals. Pathogenesis of metastatic calcification Metastatic calcification occurs due to excessive binding of inorganic phosphate ions with ​ calcium ions, which are elevated due to underlying metabolic derangement. This leads to formation of precipitates of calcium phosphate at the preferential sites. Metastatic calcification is reversible upon correction of underlying metabolic disorder. GANGRENE Gangrene is a form of necrosis of tissue with superadded putrefaction. The type of necrosis is usually coagulative due to ischaemia (e.g.

ETIOLOGY OF CELL INJURY: 1. Genetic causes • Developmental defects: Errors in morphogenesis • Cytogenetic (Karyotypic) defects: chromosomal abnormalities • Single-gene defects: Mendelian disorders • Multifactorial inheritance disorders. 2. Acquired causes • Hypoxia and ischaemia • Physical agents • Chemical agents and drugs • Microbial agents • Immunologic agents • Nutritional derangements • Aging • Psychogenic diseases • Iatrogenic factors • Idiopathic diseases. 2.1. Oxygen deprivation: HYPOXIA Ischemia (loss of blood supply). Inadequate oxygenation (cardio respiratory failure). Loss of oxygen carrying capacity of the blood (anemia or CO poisoning). 2.2. PHYSICAL AGENTS: Trauma Heat Cold Radiation Electric shock 2.3. CHEMICAL AGENTS AND DRUGS: Endogenous products: urea, glucose Exogenous agents Therapeutic drugs: hormones Nontherapeutic agents: lead or alcohol. 2.4. INFECTIOUS AGENTS: Viruses Rickettsiae Bacteria Fungi Parasites 2.5. Abnormal immunological reactions: The immune process is normally protective but in certain circumstances the reaction may become deranged. Hypersensitivity to various substances can lead to anaphylaxis or to more localized lesions such as asthma. In other circumstances the immune process may act against the body cells – autoimmunity. 2.6. Nutritional imbalances: Protein-calorie deficiencies are the most examples of nutrition deficiencies. Vitamins deficiency. Excess in nutrition are important causes of morbidity and mortality. Excess calories and diet rich in animal fat are now strongly implicated in the development of atherosclerosis.

  • Cardiovascular System Note: the Cardiovascular System Develops Early (Week-3), Enabling the Embryo to Grow Beyond the Short
    Cardiovascular System Note: The cardiovascular system develops early (week-3), enabling the embryo to grow beyond the short distances over which diffusion is efficient for transferring 2O , CO2, and cellular nutrients & wastes. Heart: Beginning as a simple tube, the heart undergoes differential growth into a four chambered struc- ture, while it is pumping blood throughout the embryo and into extra-embryonic membranes. Angiogenesis begins with blood island formation in splanchnic mesoderm of the yolk sac and allantois. Vessel formation occurs when island vesicles coalesce, sprout buds, and fuse to form vascular channels. Hematopoiesis (blood cell formation) occurs in the liver and spleen and later in the bone marrow. The transition from fetal to adult circulation involves new vessel formation, vessel merger, and degeneration of early vessels. Formation of a Tubular Heart: The first evidence of heart develop- amnionic cavity ment is bilateral vessel formation within ectoderm the cardiogenic plate (splanchnic meso- embryo derm situated anterior to the embryo).

  • Atrial-Myxomas.Pdf
    Atrial myxomas Atrial myxomas are the most common primary heart tumors. They are benign intracavitary cardiac neoplasms and accounting for one-third to one-half of cases at postmortem and for about three quarter of tumors treated surgically (Braunwald 2001). Because of nonspecific symptoms, early diagnosis may be a challenge. Left atrial myxoma may or may not produce characteristic findings on auscultation. Most atrial myxomas, whether left or right, arise from the atrial septum, usually from the region of the limbus of fossa ovalis. About 10% have other sites of origin, particularly posterior wall, anterior wall and the appendages (in order of frequency) (McAllister 1979). (Two- dimensional echocardiography is the diagnostic procedure of choice. Most atrial myxomas are benign and can be removed by surgical resection. Pathophysiology Myxomas account for 40-50% of primary cardiac tumors. Approximately 90% are solitary and pedunculated, and 75-85% occur in the left atrial cavity. Up to 25% of cases are found in the right atrium. Most cases are sporadic. Approximately 10% are familial and are transmitted in an autosomal dominant mode. Multiple tumors occur in approximately 50% of familial cases and are more frequently located in the ventricle (13% vs 2% in sporadic cases). Myxomas are polypoid, round, or oval. They are gelatinous with a smooth or lobulated surface and usually are white, yellowish, or brown such as of the figures 1 and 2 Fig. 1 Pathology specimens of multiple small myxomas resected from the right atrial surface.
