Topics for General and Systemic Pathology
Find educational topics for General and Systemic Pathology aligned with the Zambian tertiary curriculum.
Hypothalamic-Pituitary-Thyroid Axis Disorders
No questions yet
This topic integrates disorders affecting the hypothalamic-pituitary-thyroid (HPT) axis. Zambian university students will learn to differentiate primary thyroid disorders (problem at the thyroid gland level) from secondary (pituitary) and tertiary (hypothalamic) disorders. Primary hypothyroidism (e.g., Hashimoto's) shows high TSH and low T4, while secondary/tertiary hypothyroidism shows inappropriately low or normal …
Paraneoplastic Endocrine Syndromes
No questions yet
This topic explores paraneoplastic endocrine syndromes, where non-endocrine tumors secrete hormones or hormone-like substances, leading to clinical syndromes. Zambian tertiary students will study classic examples such as ectopic ACTH secretion (Cushing syndrome from lung cancer), SIADH (hyponatremia from small cell lung cancer), and hypercalcemia of malignancy (often from PTHrP secretion …
Autoimmune Endocrine Diseases
3 Questions
This topic covers autoimmune diseases targeting endocrine glands, a major cause of endocrine dysfunction. Zambian university students will learn about Hashimoto's thyroiditis (leading to hypothyroidism), Graves' disease (causing hyperthyroidism), autoimmune adrenalitis (Addison's disease), and autoimmune polyglandular syndromes. The pathogenesis involves loss of self-tolerance, production of autoantibodies, and lymphocytic infiltration leading …
Endocrine Disorders in Pregnancy
No questions yet
This topic addresses the unique interactions between pregnancy and the endocrine system, focusing on disorders that arise or are exacerbated during gestation. Zambian tertiary students in obstetrics and endocrinology will study gestational diabetes mellitus, thyroid disorders in pregnancy (both hyperthyroidism and hypothyroidism, which can affect fetal development), and preeclampsia (a …
Endocrine Surgery and Iatrogenic Disorders
No questions yet
This topic covers complications related to endocrine surgery and iatrogenic (physician-induced) endocrine disorders. Zambian university students in surgery and internal medicine will learn about post-thyroidectomy hypoparathyroidism (a common cause of hypocalcemia) and recurrent laryngeal nerve injury. Iatrogenic disorders include Cushing syndrome from exogenous glucocorticoid use, hypothyroidism from anti-thyroid drugs or …
Laboratory Diagnosis in Endocrinology
No questions yet
This topic focuses on the principles of laboratory testing for endocrine disorders, a critical skill for Zambian tertiary students in clinical medicine, pathology, and laboratory sciences. You will learn the interpretation of key hormone assays: thyroid function tests (TSH, T4, T3), cortisol and ACTH levels for adrenal disorders, PTH and …
Dermatopathology: Approach to Skin Biopsy
No questions yet
This topic provides a systematic approach to the histopathological examination of skin biopsies, a core skill in dermatopathology. Zambian tertiary students in pathology and dermatology will learn the stepwise analysis: identifying the layer of the skin primarily involved (epidermis, dermis, subcutaneous tissue), characterizing the inflammatory cell infiltrate (if present), and …
Genetic Basis of Endocrine Tumors
No questions yet
This topic explores the genetic underpinnings of familial and sporadic endocrine tumors, an advancing area in molecular pathology. Zambian university students will learn about key genetic associations: RET proto-oncogene mutations in MEN II and familial medullary thyroid carcinoma, MEN1 gene mutations in MEN I, and BRCA1/2 mutations associated with hereditary …
Systemic Effects of Endocrine Disorders
No questions yet
This integrative topic examines the wide-ranging systemic effects of major endocrine disorders, highlighting why they are considered systemic diseases. Zambian tertiary students will synthesize how cortisol excess (Cushing's) affects nearly every organ system (causing osteoporosis, diabetes, hypertension, immunosuppression). Similarly, thyroid hormone imbalance impacts metabolism, heart rate, nervous system function, and …
