Each of the 6 modules below is engineered using atomic retrieval prompts: every card isolates a single high-yield rule, diagnostic criterion, statutory article, deadline, or clinical mechanism.

Module 1 (BASIC): Endocrinology I — Pituitary, Thyroid (Graves vs Hashimoto), Adrenal (Cushing vs Addison) & Calcium/PTH Disorders

Deck Overview: Hypothalamic-pituitary axis, hyperthyroidism and hypothyroidism, adrenal cortical diseases, and calcium homeostasis

# Front (Active Recall Prompt) Back (Verified Exam Answer & Explanation)
1 What embryonic origins distinguish the anterior pituitary (adenohypophysis) from the posterior pituitary (neurohypophysis)? The anterior pituitary derives from oral ectoderm (an invagination of the stomodeum called Rathke pouch); the posterior pituitary derives from neuroectoderm of the diencephalon (floor of the third ventricle).
2 Where are Antidiuretic Hormone (ADH) and Oxytocin synthesized, and what triggers their release from the neurohypophysis? Synthesized in hypothalamic cell bodies: ADH primarily in the supraoptic nucleus (stimulated by increased serum osmolality or severe hypovolemia); Oxytocin primarily in the paraventricular nucleus (stimulated by suckling and cervical dilation); transported along axons to the posterior pituitary for release.
3 What are the clinical presentations of a Prolactinoma in women versus men, and what is the first-line therapy? Women: galactorrhea, oligomenorrhea/amenorrhea, and infertility (prolactin suppresses GnRH); Men: decreased libido, erectile dysfunction, and mass-effect headaches or bitemporal hemianopia; first-line medical therapy is Dopamine D2 receptor agonists (Cabergoline or Bromocriptine).
4 What is the initial screening test and the confirmatory test for Acromegaly in adults? Initial screening test: Elevated serum Insulin-like Growth Factor 1 (IGF-1) level; Confirmatory test: Oral Glucose Tolerance Test (OGTT), showing failure of an oral 75 g glucose load to suppress Growth Hormone (GH) to < 1 ng/mL (in normal individuals, hyperglycemia suppresses GH).
5 How does the Desmopressin (DDAVP) test differentiate Central Diabetes Insipidus from Nephrogenic Diabetes Insipidus? Following water deprivation, administration of DDAVP causes a significant increase in urine osmolality (> 50%) in Central DI (correcting the ADH deficiency); in Nephrogenic DI, there is minimal or no response (< 50% increase) due to renal ADH resistance.
6 What is the underlying immunological mechanism and classic clinical triad of Graves Disease? Autoantibodies stimulating the TSH receptor (Thyroid-Stimulating Immunoglobulins, TSI); classic triad: 1) Hyperthyroidism with diffuse goiter; 2) Graves ophthalmopathy / exophthalmos (retro-orbital T-cell cytokine activation of fibroblasts producing glycosaminoglycans); 3) Pretibial myxedema (thyroid dermopathy).

Module 2 (INTERMEDIATE): Endocrinology II — Type 1 & Type 2 Diabetes, DKA vs HHS, Pheochromocytoma & Multiple Endocrine Neoplasia (MEN 1 & 2)

Deck Overview: Diabetes mellitus pathogenesis and complications, diabetic emergencies, chromaffin cell neoplasms, and MEN syndromes

# 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.

Module 3 (BASIC): Neurology & Neuropathology — Stroke Syndromes, Seizures, Demyelinating (MS, GBS), Movement & Dementia Disorders

Deck Overview: Cerebrovascular accidents, epilepsy classifications, neuroimmunology, basal ganglia disorders, and neurodegenerative dementias

# Front (Active Recall Prompt) Back (Verified Exam Answer & Explanation)
1 What neurological deficits characterize a Middle Cerebral Artery (MCA) cortical stroke? Contralateral hemiparesis and hemisensory loss predominantly involving the face and upper extremity (arm > leg); conjugate gaze deviation toward the lesion side; if dominant hemisphere (left): aphasia (Broca or Wernicke); if non-dominant hemisphere (right): hemineglect and anosognosia.
2 What motor, sensory, and behavioral deficits define an Anterior Cerebral Artery (ACA) stroke? Contralateral hemiparesis and hemisensory loss predominantly affecting the lower extremity (leg > arm); urinary incontinence; abulia, apathy, lack of initiative, and primitive grasp and suck reflexes due to frontal lobe infarction.
3 What visual field defect occurs in a Posterior Cerebral Artery (PCA) stroke, and why is macular vision preserved? Contralateral homonymous hemianopia with MACULAR SPARING; macular cortical representation in the occipital pole has a collateral dual blood supply from both the PCA and terminal cortical branches of the Middle Cerebral Artery (MCA).
4 What cranial nerve and cerebellar deficits comprise the Lateral Medullary (Wallenberg) Syndrome? PICA or vertebral artery occlusion; Nucleus ambiguus (CN IX, X) damage causes dysphagia, hoarseness, and loss of gag reflex; Vestibular nuclei cause vertigo, nystagmus; Inferior cerebellar peduncle causes ipsilateral limb ataxia; Spinal trigeminal tract causes ipsilateral facial sensory loss; Spinothalamic tract causes contralateral body sensory loss; Descending sympathetics cause ipsilateral Horner syndrome.
5 What distinct cranial nerve finding differentiates Lateral Pontine Syndrome (AICA occlusion) from Lateral Medullary Syndrome (PICA occlusion)? Facial Nerve (CN VII) nucleus and fascicle damage is unique to Lateral Pontine Syndrome (AICA), causing ipsilateral complete facial muscle paralysis (loss of forehead and lower facial movement), loss of corneal reflex efferent limb, and loss of taste on anterior 2/3 tongue, plus ipsilateral hearing loss (CN VIII).
6 What underlying microvascular pathology causes Lacunar Infarcts, and what are the classic clinical syndromes? Lipohyalinosis and microatheroma of small penetrating lenticulostriate and thalamoperforating arteries due to chronic hypertension and diabetes; classic syndromes include Pure Motor Hemiparesis (posterior limb of internal capsule) and Pure Sensory Stroke (ventral posterolateral nucleus of thalamus); lacks cortical signs.

Deck Overview: Inflammatory and autoimmune arthropathies, connective tissue diseases, crystal deposition diseases, and systemic vasculitis

# Front (Active Recall Prompt) Back (Verified Exam Answer & Explanation)
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).
4 What are the sensitivity and specificity profiles of Anti-Nuclear Antibodies (ANA), Anti-dsDNA, and Anti-Smith (anti-Sm) in SLE? ANA: highly sensitive (> 98%) screening test, but low specificity; Anti-dsDNA: highly specific (> 95%), titers correlate with disease activity and active lupus nephritis; Anti-Smith (anti-Sm, directed against snRNPs): highly specific (> 99%), but does NOT track with disease activity.
5 What are the histopathological findings on light microscopy and immunofluorescence in Class IV Lupus Nephritis (Diffuse Proliferative Glomerulonephritis)? Light microscopy shows diffuse endothelial and mesangial cell proliferation with subendothelial immune complex deposits producing characteristic 'wire-loop' capillary thickening; immunofluorescence reveals granular 'full house' staining (positive for IgG, IgA, IgM, C3, and C1q).
6 What medications commonly induce Drug-Induced Lupus Erythematosus (DILE), and what autoantibody is present in > 95% of cases? Hydralazine, Procainamide, and Isoniazid (slow acetylators at higher risk); presents with fever, arthralgias, and serositis, characteristically SPARING the central nervous system and kidneys; characterized by Anti-Histone Antibodies in > 95% of patients; resolves after drug cessation.

# Front (Active Recall Prompt) Back (Verified Exam Answer & Explanation)
1 What endocrine switch triggers the mid-cycle Luteinizing Hormone (LH) surge that induces ovulation? During the late follicular phase, sustained high levels of estradiol (> 200 pg/mL for >= 48 hours) from the dominant follicle switch estrogen feedback at the anterior pituitary and hypothalamus from NEGATIVE to POSITIVE feedback, triggering the massive pre-ovulatory LH surge.
2 What are the three components of the Rotterdam Diagnostic Criteria for Polycystic Ovary Syndrome (PCOS)? Diagnosis requires at least 2 of 3 features (after excluding other etiologies): 1) Oligo- or anovulation (irregular/absent menses); 2) Clinical or biochemical hyperandrogenism (hirsutism, acne, elevated free testosterone); 3) Polycystic ovaries on ultrasound (>= 20 follicles per ovary or ovarian volume >= 10 mL).
3 What physical exam and karyotype features differentiate Müllerian Agenesis (MRKH Syndrome) from Androgen Insensitivity Syndrome (AIS)? Müllerian Agenesis: 46,XX karyotype, normal ovaries, normal female testosterone levels, normal female pubic and axillary hair, absent uterus and upper 2/3 vagina; Androgen Insensitivity Syndrome: 46,XY karyotype, undescended functional testes, normal male testosterone levels, absent pubic and axillary hair (androgen resistance), breast development (aromatization), absent uterus.
4 What endocrine, genetic, and physical findings define Turner Syndrome (45,XO) presenting with primary amenorrhea? Complete or partial monosomy X (45,XO); 'streak ovaries' (ovarian dysgenesis) resulting in hypergonadotropic hypogonadism (elevated FSH and LH, low estrogen); physical features include short stature, webbed neck (cystic hygroma remnant), shield chest, bicuspid aortic valve, and coarctation of the aorta.
5 What developmental migratory defect causes Kallmann Syndrome, and what sensory deficit accompanies it? Failure of GnRH-secreting neurons to migrate from the olfactory placode to the hypothalamus, accompanied by aplasia/hypoplasia of the olfactory bulbs; causes congenital hypogonadotropic hypogonadism (low GnRH, low LH/FSH, low sex steroids, absent puberty) and ANOSMIA (loss of smell).
6 What blood pressure and organ criteria define Preeclampsia after 20 weeks of gestation? New-onset hypertension (SBP >= 140 or DBP >= 90 mmHg on 2 occasions >= 4 hours apart) occurring after 20 weeks gestation in a previously normotensive woman PLUS proteinuria (>= 300 mg/24-hr or protein/Cr ratio >= 0.3) OR severe features (thrombocytopenia < 100k, Cr > 1.1, transaminases 2x normal, pulmonary edema, cerebral/visual symptoms).

1 What are the four fundamental physiological classifications of circulatory shock? 1) Hypovolemic shock (loss of intravascular fluid volume); 2) Cardiogenic shock (primary myocardial pump failure); 3) Distributive shock (profound systemic vasodilation and vascular permeability); 4) Obstructive shock (physical mechanical obstruction to cardiac inflow or outflow).
2 What is the characteristic pulmonary artery catheter hemodynamic profile in acute Hypovolemic Shock? Central Venous Pressure (CVP): Decreased; Pulmonary Capillary Wedge Pressure (PCWP): Decreased; Cardiac Output / Index (CO/CI): Decreased; Systemic Vascular Resistance (SVR): Markedly Increased (compensatory vasoconstriction); Mixed Venous Oxygen Saturation (SvO2): Decreased (< 65%, high tissue oxygen extraction).

5 What hemodynamic profile and physical examination hallmarks distinguish Neurogenic Shock from other forms of shock? Disruption of descending sympathetic autonomic pathways following high spinal cord injury (above T6); loss of vascular tone and cardiac sympathetic drive leads to Decreased CVP, Decreased PCWP, Decreased SVR, and Normal/Decreased CO; physical hallmark: severe HYPOTENSION accompanied by paradoxical BRADYCARDIA and warm, dry skin.
6 What hemodynamic parameter equalization defines Cardiac Tamponade on cardiac catheterization, and what is Beck Triad? Pathognomonic EQUALIZATION of end-diastolic pressures in all four cardiac chambers (CVP = RV end-diastolic = PCWP = LV end-diastolic pressure); Beck Triad: 1) Hypotension; 2) Distended neck veins (elevated JVP); 3) Muffled heart sounds; accompanied by pulsus paradoxus (> 10 mmHg drop in SBP on inspiration).
