Leukotrienes C4 and D4(TOPNOTCH)Robbins Basic Pathology, 9th ed., p. 203
A lipid mediator produced by some mast cell populations, not derived from arachidonic acid, causing platelet aggregation, increased vascular permeability, and vasodilation.
Platelet-activating factor(PAF)(TOPNOTCH) Robbins Basic Pathology, 9th ed., p. 203
True or False. Atopic individuals tend to have higher serum IgE levels and more IL-4 producing Th2 cells.
This disease presents with nephritis and lung hemorrhage due to complement and Fc receptor-mediated inflammation due to antibody against noncollagenous protein in basement membranes of kidney glomeruli and lung alveoli.
Goodpasture syndrome(TOPNOTCH)Robbbins Basic Pathology, 9th ed., p. 206
This disease causes demyelination in CNS is perivascular inflammation due to inflammation mediated by TH1 and TH17 cytokines, myelin destruction by activated macrophages.
Multiple sclerosis(TOPNOTCH) Robbins Basic Pathology, 9th ed., p. 209
Type of immunity primarily affected by AIDS
Mucocutatnous ulcerations involving the mouth, esophagus, external genitalia, and perianal region in AIDS patient may be caused by
Herpes simplex virus infection(TOPNOTCH)
An 18 year old female presents with a day-old circular erythematous plaque with vesicles on her neck. She relates a history of wearing a new metallic pendant three days ago, and has had a similar history with other metallic jewelry. If the plaque is biopsied, which inflammatory cell is expected to predominate? (A) neutrophil (B) eosinophil (C) mast cell (D) lymphocyte
Lymphocyte (TOPNOTCH) Robbins Basic Pathology, 8th ed. Pp128-130
An 8 year old male with a strep throat four weeks ago develops tea-colored urine. A kidney biopsy showed hypercellular glomeruli with neutrophils. Electron microscopy showed subepithelial "humps." These findings are caused by (A) antibodies against glomerular basement membrane (B) antibodies against endothelium (C) immune complex deposition (D) T-cell mediated recruitment of neutrophils
immune complex deposition (TOPNOTCH) Robbins Basic Pathology, 8th ed. P126
A 5 year old female with a strep throat two weeks ago develops joint pains and fever. Auscultation revealed a friction rub. What type of hypersensitivity is responsible?
Type II (TOPNOTCH)Robbins Basic Pathology, 8th Ed p.120
A 33 year old female presents with morning stiffness of the PIP and MCP joints of the hands. On workup, she is positive for rheumatoid factor. Which of the following is expected in the involved joints? (A) synovial hypertrophy with dense lymphoid aggregates (B) synovial atrophy with epithelioid macrophages (C) synovial hypertrophy devoid of leukocytes (D) synovial atrophy with dense lymphoid aggregates
synovial atrophy with dense lymphoid aggregates (TOPNOTCH) Robbins Basic Pathology, 8th ed. Pp145-146
A 50 year old female with chronic red eye is diagnosed with keratoconjunctivitis sicca and is referred to by her ophthalmologist for bilateral infraauricular masses. Her oral mucosa has multiple fissures. Biopsy of the infraauricular masses will likely show (A) epithelial and myoepithelial cells admixed with chondroid stroma (B) lymphoplasmacytic infiltration with ductal hyperplasia (C) basaloid cells in cribriform structures (D) highly pleomorphic epithelial cells and numerous atypical mitoses
lymphoplasmacytic infiltration with ductal hyperplasia (TOPNOTCH) Robbins Basic Pathology, 8th ed. Pp148-149
Patients with diffuse scleroderma have sclerotic atrophy of the skin. Which other organ is most commonly involved? (A) kidneys (B) heart (C) lungs (D) gastrointestinal tract
gastrointestinal tract (90% of patients) (TOPNOTCH) Robbins Basic Pathology, 8th ed. Pp 149-150
A 22 year old male has unprotected sex and develops generalized lymphadenopathy five days later. The following month, he tests positive on HIV screening. Excision biopsy of one of his lymph nodes would likely show (A) marked follicular hyperplasia (B) epithelioid macrophages and giant cells (C) diffuse infiltration by atypical mononuclear cells (D) subcapsular necrosis
marked follicular hyperplasia (TOPNOTCH) Robbins Basic Pathology, 8th ed. P 165
