| # | Front (Active Recall Prompt) | Back (Verified Exam Answer & Explanation) |
| :--- | :--- | :--- |
| **1** | What are the embryological origins of the anterior and posterior pituitary? | The adenohypophysis develops from oral ectoderm: Rathke’s pouch grows upward from the primitive mouth. The neurohypophysis develops from neural ectoderm extending downward from the ventral diencephalon. Their meeting creates an organ with two developmental origins. The posterior lobe contains hypothalamic axons and releases hormones synthesized in hypothalamic neurons; it does not synthesize them as an independent endocrine gland. |
| **2** | Where are vasopressin and oxytocin synthesized, and what stimulates their release? | Both are made by magnocellular neurons in the supraoptic and paraventricular hypothalamic nuclei, then transported to posterior-pituitary terminals. Vasopressin predominates in the supraoptic nucleus and oxytocin in the paraventricular nucleus, but neither location is exclusive. Increased plasma osmolality or reduced effective circulating volume stimulates vasopressin release. Suckling and cervical or vaginal stretch promote oxytocin release, supporting milk ejection and uterine contraction. |
| **3** | How can a prolactinoma present, and is medication always the only first-line option? | Excess prolactin suppresses reproductive function, causing menstrual disturbance, infertility, reduced libido or erectile dysfunction; galactorrhea may occur. Larger tumors can cause headache or visual-field loss. Exclude other causes of elevated prolactin before attributing it to an adenoma. Cabergoline is generally the preferred dopamine agonist. The 2023 Pituitary Society consensus also supports discussing expert surgery as a first-line option for selected microprolactinomas and well-encapsulated macroprolactinomas. |
| **4** | How does the 2024 acromegaly consensus use IGF-1 and an oral glucose tolerance test? | In a patient with typical clinical features, age-adjusted IGF-1 above 1.3 times the upper limit of normal confirms the diagnosis under this consensus. Equivocal results require reassessment, including repeat IGF-1 with a validated assay; a glucose-suppression test can help. GH suppression thresholds depend on assay and patient factors. Do not require one universal GH cutoff or an oral glucose tolerance test in every case; pituitary imaging follows biochemical assessment. |
| **5** | How are vasopressin deficiency and resistance distinguished, and why can a simple desmopressin rule mislead? | Vasopressin deficiency, formerly central diabetes insipidus, reflects inadequate hormone production or release; resistance, formerly nephrogenic diabetes insipidus, reflects reduced renal response. Both can cause hypotonic polyuria. Complete deficiency usually responds strongly to desmopressin, whereas complete resistance responds poorly. Partial disorders and primary polydipsia overlap, so a percentage change alone is insufficient. Specialist-supervised testing, including appropriately stimulated copeptin where available, improves discrimination; unsupervised water deprivation is unsafe. |
| **6** | What causes Graves disease, and must its thyroid, eye and skin findings all be present? | Stimulating antibodies against the TSH receptor increase thyroid hormone production. Hyperthyroidism with a diffuse goiter is a common pattern; orbitopathy and pretibial dermopathy are characteristic associations but are not required. Eye disease can occasionally occur without current hyperthyroidism. TRAb or thyroid-stimulating immunoglobulin testing supports the diagnosis, with uptake or ultrasound assessment when appropriate. Do not treat the traditional triad as mandatory diagnostic criteria. |

| # | Front (Active Recall Prompt) | Back (Verified Exam Answer & Explanation) |
| :--- | :--- | :--- |
| **1** | What is the autoimmune pathogenesis, genetic HLA association, and primary circulating autoantibodies in Type 1 Diabetes Mellitus? | Autoimmune destruction of pancreatic beta cells mediated by CD8+ cytotoxic T cells; associated with HLA-DR3, HLA-DR4, and HLA-DQ2/DQ8; autoantibodies include Anti-Glutamic Acid Decarboxylase (anti-GAD65), Anti-Islet Cell Antigen-2 (anti-IA-2), and Anti-Zinc Transporter 8 (anti-ZnT8). |
| **2** | What dual defects drive Type 2 Diabetes Mellitus, and what histopathological deposit characterizes pancreatic islets in long-standing disease? | Progressive peripheral insulin resistance (skeletal muscle, liver, adipose) combined with beta-cell secretory failure; histopathologically characterized by dense extracellular deposition of AMYLOID polypeptide (amylin) within the islets of Langerhans. |
| **3** | What are the four formal ADA diagnostic laboratory criteria for Diabetes Mellitus? | 1) Fasting plasma glucose >= 126 mg/dL (after 8-hr fast); 2) 2-hour plasma glucose >= 200 mg/dL during a 75 g OGTT; 3) Hemoglobin A1c >= 6.5%; 4) In a patient with classic symptoms of hyperglycemia (polyuria, polydipsia, weight loss), a random plasma glucose >= 200 mg/dL. |
| **4** | How does C-peptide measurement distinguish factitious insulin injection from an insulinoma or sulfonylurea overdose? | C-peptide is cleaved in equimolar amounts to endogenous insulin; Exogenous insulin administration causes hypoglycemia with ELEVATED insulin and UNDETECTABLE / low C-peptide; Insulinoma and sulfonylurea toxicity produce hypoglycemia with ELEVATED insulin and ELEVATED C-peptide. |
| **5** | What is the biochemical cascade that generates ketone bodies in Diabetic Ketoacidosis (DKA)? | Absolute insulin deficiency and glucagon excess stimulate hormone-sensitive lipase in adipose tissue, releasing free fatty acids; in the liver, increased carnitine palmitoyltransferase-1 (CPT-1) activity shunts fatty acids into beta-oxidation, producing excess Acetyl-CoA converted into beta-hydroxybutyrate and acetoacetate. |
| **6** | What is the pathophysiological reason that Hyperosmolar Hyperglycemic State (HHS) lacks significant ketosis compared to DKA? | In HHS, residual endogenous insulin secretion is sufficient to suppress lipolysis in adipose tissue and inhibit hepatic ketogenesis, but insufficient to prevent severe hepatic gluconeogenesis and peripheral hyperglycemia (> 600 mg/dL), leading to profound hyperosmolar diuresis. |

| **1** | What is the immunological pathogenesis of Rheumatoid Arthritis (RA), and which hand joints are characteristically involved versus spared? | Autoimmune synovitis driven by CD4+ Th1/Th17 cells producing TNF-alpha and IL-6, causing invasive hyperplastic vascularized synovium (PANNUS) that destroys articular cartilage and bone; symmetrically involves MCP, PIP, and wrist joints; characteristically SPARES the Distal Interphalangeal (DIP) joints. |
| **2** | How do Rheumatoid Factor (RF) and Anti-Cyclic Citrullinated Peptide (anti-CCP) antibodies compare in sensitivity and specificity for RA? | Rheumatoid Factor (IgM antibody against the Fc region of human IgG) has moderate sensitivity (70-80%) but poor specificity (found in hepatitis C, Sjogren, healthy elderly); Anti-CCP (ACPA) antibodies have similar sensitivity (70-80%) but MUCH HIGHER SPECIFICITY (> 95-98%) and predict aggressive erosive joint disease. |
| **3** | What joint deformities and extra-articular manifestations characterize advanced Rheumatoid Arthritis? | Deformities: Swan-neck deformity (PIP hyperextension, DIP flexion), Boutonniere deformity (PIP flexion, DIP hyperextension), and ulnar deviation of fingers at MCPs; Extra-articular: subcutaneous rheumatoid nodules (fibrinoid necrosis surrounded by palisading histiocytes), rheumatoid pleuritis, interstitial lung disease, and Felty syndrome (RA, splenomegaly, neutropenia). |
