Q

What characterizes the infection control mechanism in acute viral hepatitis?

A

Cytotoxic T-cell-mediated signals cause hepatocyte apoptosis

This process is marked microscopically by the presence of Councilman bodies.

Q

True or False: Cytotoxic T-cell-mediated signals promote hepatocyte survival.

A

False

These signals lead to apoptosis, not survival.

A

Spread throughout a body cavity.

24
Q

A

Spread along nerves or nerve sheaths.

25
What is dermatomyositis?
An inflammatory myopathy that primarily affects striated muscle and skin.
26
What are the diagnostic findings in dermatomyositis?
Elevated muscle enzymes (e.g., creatinine kinase) and positive autoantibodies (e.g., anti-Jo-1).
27
What does a muscle biopsy in dermatomyositis show?
Perimysial inflammatory infiltrates and perifascicular atrophy.
28
What complications can arise from inflammatory myopathies?
Interstitial lung disease and myocarditis.
29
What enzyme deficiency is associated with congenital adrenal hyperplasia?
21-Hydroxylase deficiency.
30
What are the symptoms of 21-Hydroxylase deficiency?
Salt wasting, hypotension, ambiguous genitalia in boys, absent puberty.
31
What are common causes of bacterial meningitis?
Streptococcus pneumoniae, Neisseria meningitidis, Listeria monocytogenes.
32
What features suggest preeclampsia?
Severe hypertension and elevated liver function tests.
33
What is HELLP syndrome?
Hemolysis, Elevated Liver Enzymes, Low Platelets.
34
What complication is associated with HELLP syndrome?
Hepatic subcapsular hematoma.
35
What increases the risk of seizures in preeclampsia?
Cerebral vasospasm, thrombosis, and edema.

What is Kartagener Syndrome (KS)?
A condition characterized by a dynein arm defect in cilia, leading to respiratory infections and male infertility due to immotile sperm.
41
What is delirium?
An acute-onset confusional state characterized by waxing and waning mental status changes and impaired attention. It occurs secondary to an underlying medical condition.
42
What are the symptoms of delirium?
Disorientation, agitation, psychosis, and sleep disturbances may occur.
43
What is the primary management for delirium?
Treating the underlying cause of the condition.
44
What are the risks associated with delirium?
The elderly and those with preexisting cognitive disorders are at a higher risk.
45
What medications can be used for acute treatment of agitation in delirium?
High-potency first-generation antipsychotics (e.g., haloperidol) and some second-generation antipsychotics (e.g., quetiapine).
46
What is Major Depressive Disorder?
Characterized by depressed mood and significant functional impairment, with at least 5 of 9 symptoms including SIGECAPS.
47
What does SIGECAPS stand for?
Sleep disturbance, loss of Interest, excessive Guilt, low Energy, impaired Concentration, Appetite disturbance, Psychomotor agitation/retardation, and Suicidal ideation.
48
What is Hepatocellular adenoma?
An uncommon, benign liver tumor often associated with estrogen exposure and anabolic steroid use, typically asymptomatic but may cause abdominal pain.
49
What are the clinical manifestations of digoxin toxicity?
Life-threatening arrhythmias, gastrointestinal disturbances, weakness, and color vision alterations.
50
What is dermatomyositis?
An inflammatory myopathy characterized by proximal muscle weakness and a heliotrope rash, with elevated muscle enzymes and specific autoantibodies.
51
What are the complications of inflammatory myopathies?
Dysphagia, pulmonary aspiration, interstitial lung disease, and myocarditis.
52
What is the significance of enzyme deficiency in adrenal steroidogenesis?
It can lead to various disorders, affecting disease prevalence and duration.
