Study Notes
Exudative Pleural Effusions in TB
- Characterized by very elevated protein levels (> 4 g/dL)
- Lymphocytic leukocytosis is common
- Low glucose levels present (often < 60 mg/dL)
Aortic Stenosis Causes
- Elderly: Degenerative calcification of aortic valve leaflets
- Younger individuals: Bicuspid aortic valve
- Nondeveloped countries: Rheumatic valve disease
Mast Cell Stabilizers
- Two agents indicated for allergic conjunctivitis:
- Olopatadine
- Azelastine
Secondary Digital Clubbing Causes
- Most common causes include:
- Lung malignancies
- Cystic fibrosis
- Right-to-left cardiac shunts
Hashimoto Thyroiditis and Anti-TPO Antibodies
- Over 90% of patients have antithyroid peroxidase (anti-TPO) antibodies
- High anti-TPO titers increase risk of progression to overt hypothyroidism
- Associated with increased risk of miscarriage in both euthyroid and hypothyroid women
Malaria Chemoprophylaxis
- High rates of chloroquine resistance in endemic countries
- Recommended chemoprophylaxis should start 2 weeks before travel, continue during, and for 4 weeks after
- Potential medications:
- Mefloquine
- Doxycycline
- Atovaquone-proguanil
Asterixis Causes and Treatments
- Can occur due to hepatic encephalopathy (HE), uremic encephalopathy, or hypercapnia
- Treatment for HE: Lactulose
- Treatment for uremic encephalopathy: Urgent hemodialysis
Primary Biliary Cholangitis (PBC)
- Chronic liver disease due to autoimmune destruction of small bile ducts
- Common in middle-aged women, symptoms include fatigue and pruritus
- Diagnosis confirmed by serum anti-mitochondrial antibody titers
Transvenous Lead Placement Complications
- Can lead to severe tricuspid regurgitation due to valve leaflet damage
- Symptoms to suspect: Right-sided heart failure after pacemaker or cardioverter-defibrillator placement
Cardiac Tamponade and AAA
- Can occur as a catastrophic complication of abdominal aortic aneurysm (AAA)
- Signs: Hypotension, tachycardia, distended neck veins, pulsus paradoxus, sudden onset tearing chest pain radiating to the back
Peripheral Artery Aneurysms
- Two most common peripheral artery aneurysms associated with AAA:
- Popliteal artery
- Femoral artery
Post-Cardiac Surgery Pleural Effusions
- Manage with observation if:
- Small to moderate size
- Early onset (post-operative day 1 or 2)
- No respiratory symptoms present
Paraesophageal Hiatal Hernia
- Symptoms include nausea, dysphagia, chest pain, and retrocardiac air-fluid levels on imaging
- Condition characterized by the gastric fundus migrating into the thoracic cavity
Complicated Diverticulitis Management
- Refers to diverticulitis with abscess, perforation, obstruction, or fistula
- Next step: Percutaneous abscess drainage under CT guidance
- Surgical drainage if percutaneous method fails
Focal Nodular Hyperplasia Imaging
- Associated with anomalous arteries
- Imaging findings: Arterial flow and central, stellate scar
Causes of Anorectal Fistula
- Secondary to several conditions, including:
- Rupture of perianal abscess
- Crohn's disease
- Malignancy/radiation proctitis
- Infection (lymphogranuloma venereum)
Postcholecystectomy Syndrome
- Next steps in management include:
- Abdominal ultrasound
- Endoscopic retrograde cholangiopancreatography (ERCP)
Urgent Surgery for Warfarin Patients
- Patients requiring urgent surgery and are on warfarin should receive:
- Prothrombin complex concentrate (PCC) and IV vitamin K
- Alternative if PCC is unavailable: Fresh frozen plasma (FFP)
Emphysematous Cholecystitis Treatment
- Management requires emergent cholecystectomy
- Broad-spectrum antibiotics with Clostridium coverage (e.g., piperacillin-tazobactam)
Sialadenosis
- Benign, non-inflammatory enlargement of salivary glands
- Commonly associated with chronic alcohol use
