Topics for General and Systemic Pathology
Find educational topics for General and Systemic Pathology aligned with the Zambian tertiary curriculum.
Asthma and Bronchiectasis
5 Questions
This topic examines two important obstructive airway diseases: Asthma and Bronchiectasis. Zambian tertiary students in medicine and pathology will explore asthma as a chronic inflammatory disorder characterized by bronchial hyperresponsiveness, reversible airflow obstruction, and episodic symptoms. You will learn about extrinsic, intrinsic, and mixed types, along with the underlying pathophysiology …
Pneumoconioses and Occupational Lung Disease
1 Questions
This topic focuses on Pneumoconioses, a group of interstitial lung diseases caused by inhalation of mineral dusts, highly relevant for occupational health. Zambian university students in pathology, public health, and occupational medicine will study the pathogenesis, focusing on dust deposition, macrophage activation, and the release of pro-inflammatory cytokines leading to …
Adrenal Cortex: Primary Insufficiency (Addison's Disease)
4 Questions
This topic examines primary chronic adrenocortical insufficiency, known as Addison's disease, resulting from progressive destruction of the adrenal cortex. Zambian university students will learn that over 90% of the cortex must be compromised before symptoms appear. The major causes are autoimmune adrenalitis, tuberculosis, and metastatic cancers. The clinical manifestations include …
Interstitial (Atypical) Pneumonia and Lung Abscess
No questions yet
This topic details two distinct pulmonary infections: Interstitial Pneumonia and Lung Abscess. For Zambian tertiary students, interstitial pneumonia, often caused by Mycoplasma pneumoniae or viruses, is characterized by patchy inflammation confined to the alveolar walls, leading to non-productive cough and diffuse infiltrates on imaging, contrasting with the lobar consolidation of …
Adrenal Medulla and Pheochromocytoma
No questions yet
This topic focuses on the pathology of the adrenal medulla, primarily neoplasms of chromaffin cells known as pheochromocytomas. Zambian tertiary students in oncology and endocrinology will learn that these tumors secrete catecholamines (epinephrine, norepinephrine), leading to the predominant clinical feature of hypertension. This may be episodic (with spells of headache, …
Principles of Histological Staining
7 Questions
This foundational topic covers the core principles and aims of staining in histology and pathology. For Zambian tertiary students pursuing diplomas or degrees in medical laboratory science, cellular pathology, or histotechnology, understanding why and how we stain tissues is essential. The primary aim is to add contrast and color to …
Multiple Endocrine Neoplasia (MEN) Syndromes
No questions yet
This topic covers the Multiple Endocrine Neoplasia syndromes, a group of autosomal dominant disorders characterized by tumors or hyperplasias in multiple endocrine glands. Zambian university students will study MEN I (3 P's: Parathyroid, Pancreatic islet cells, Pituitary) and MEN II (Medullary Thyroid Carcinoma, Pheochromocytoma, Parathyroid hyperplasia). Understanding these patterns is …
Pelvic Inflammatory Disease (PID) and Tubal Pathology
No questions yet
This topic covers Pelvic Inflammatory Disease (PID) and associated tubal pathology, a major cause of morbidity and infertility in women. Zambian college and university students in gynecology, pathology, and public health will study PID as an ascending infection from the cervix/vagina, often caused by sexually transmitted organisms like Chlamydia trachomatis …
Dye Classification: Basic, Acidic, and Metachromatic
No questions yet
This topic delves into the histological classification of dyes based on their chemical properties and interaction with tissue components, a fundamental concept for Zambian tertiary students in pathology and medical laboratory science. Students will learn to distinguish between Basic dyes (cationic, staining acidic/anionic structures like nucleic acids - basophilia), Acidic …
