Tissue Healing and Repair
38 Questions
Tissue healing and repair are central to understanding how the body responds to injury, encompassing regeneration, scar formation, wound contraction, and fracture healing. This topic covers the proliferative capacities of labile, stable, and permanent cells, the phases of repair (inflammation, demolition, granulation tissue formation), and patterns of wound healing (primary …
Classification and Identification of Tissue Pigments
No questions yet
This topic provides a comprehensive overview of the classification, origin, and identification of various pigments found in human tissues, a fundamental concept in diagnostic pathology for Zambian tertiary students. Learners will explore the three major groups: artifact pigments (resulting from fixation like mercury or formalin), exogenous pigments (externally derived like …
Thyroid Gland: Hypothyroidism and Myxedema
4 Questions
This topic covers hypothyroidism, a condition of thyroid hormone deficiency, with a focus on its presentation in older children and adults, known as myxedema. Zambian university students will learn about the general causes, including primary thyroid failure (e.g., Hashimoto's thyroiditis), consequences of surgery or radiation, and secondary pituitary causes. The …
Hepatic Tumours and Circulatory Disorders
No questions yet
Hepatic Tumours and Circulatory Disorders cover neoplastic and vascular pathologies of the liver, including hepatocellular carcinoma (HCC), hepatic adenoma, metastatic tumors, Budd-Chiari syndrome, and passive congestion. This topic explores epidemiology, risk factors (e.g., viral hepatitis, aflatoxin, oral contraceptives), pathogenesis, morphological features, and clinical presentation. For Zambian tertiary students in medicine, …
Acute and Chronic Inflammation
65 Questions
Inflammation is a protective response to injury or infection, involving vascular, cellular, and molecular components. This topic explores acute inflammation (characterized by rapid onset, neutrophil infiltration, and cardinal signs) and chronic inflammation (featuring mononuclear cells, tissue destruction, and repair). It covers causes, mediators, morphological patterns (serous, fibrinous, suppurative, etc.), systemic …
Cretinism and Congenital Hypothyroidism
No questions yet
This topic addresses cretinism, the severe form of hypothyroidism developing in infancy or early childhood. Zambian tertiary students in paediatrics and pathology will study the devastating consequences of thyroid hormone deficiency during critical periods of development. Key features include severe mental retardation, impaired skeletal growth leading to short stature, coarse …
Neoplasia and Cancer Biology
69 Questions
Neoplasia involves the uncontrolled growth of cells leading to benign or malignant tumors. This topic covers tumor nomenclature, characteristics (differentiation, growth rate, invasion, metastasis), molecular basis (oncogenes, tumor suppressor genes, DNA repair genes), predisposing factors, and clinical features. For Zambian tertiary students in medicine, biomedical sciences, laboratory technology, or oncology, …
Gallbladder and Biliary Tract Pathology
3 Questions
Gallbladder and Biliary Tract Pathology includes disorders such as cholelithiasis, cholecystitis, cholangitis, biliary atresia, and carcinomas of the gallbladder and bile ducts. This topic covers the pathogenesis of cholesterol and pigment stones, clinical presentations of biliary colic and obstructive jaundice, complications like pancreatitis and cholangitis, and risk factors for malignancy. …
