A 62-year-old man is evaluated on postoperative day 3 following an uncomplicated laparoscopic inguinal hernia repair. He reports the acute onset of severe pain, swelling, and redness in his right first metatarsophalangeal joint that began overnight. The patient has a history of hypertension and hyperlipidemia. His temperature is 37.8°C (100.0°F), blood pressure is 135/85 mmHg, and pulse is 88/min. Physical examination reveals an exquisitely tender, warm, and erythematous right big toe. Synovial fluid analysis of the affected joint reveals a leukocyte count of 22,000/mm³ and the presence of needle-shaped, negatively birefringent crystals. Gram stain shows no organisms. Which of the following is the most appropriate next step in management?

  1. Prescribe oral indomethacinCevap
  2. B
    Administer intravenous vancomycin and ceftriaxone
  3. C
    Initiate therapy with oral allopurinol
  4. D
    Perform surgical irrigation and debridement of the joint
  5. E
    Administer intravenous furosemide

Cevap

The most appropriate next step in management is to prescribe an oral nonsteroidal anti-inflammatory drug, such as indomethacin.
This patient is experiencing an acute gout flare, which is strongly suggested by his presentation of podagra (inflammation of the first metatarsophalangeal joint) and confirmed by the synovial fluid demonstrating needle-shaped, negatively birefringent monosodium urate crystals. Acute gout attacks frequently occur in hospitalized or postoperative patients due to physiological stress, dehydration, or changes in diet and medications. The most appropriate immediate management is to reduce joint inflammation. First-line therapies for an acute gout attack include oral nonsteroidal anti-inflammatory drugs (NSAIDs) such as indomethacin, colchicine, or systemic/intra-articular glucocorticoids. Since the patient has no apparent contraindications (such as active peptic ulcer disease or severe kidney injury), an NSAID is the correct next step.

Adım Adım Çözüm

1
Evaluate the clinical presentation and physical exam findings.
The patient presents with acute monoarthritis of the first metatarsophalangeal joint (podagra), highly characteristic of a gout flare.
Identifying the specific pattern of joint involvement helps narrow the differential diagnosis between crystalline arthropathy, infectious arthritis, and autoimmune etiologies.
2
Interpret the synovial fluid analysis.
The fluid shows a moderately elevated leukocyte count (22,000/mm³) and needle-shaped, negatively birefringent crystals.
These microscopic findings confirm the diagnosis of acute monosodium urate crystal deposition (gout) and effectively rule out septic arthritis given the negative Gram stain.
3
Determine the optimal acute management.
Select a medication to rapidly halt the inflammatory cascade.
First-line agents for an acute gout flare include NSAIDs (e.g., indomethacin), colchicine, or systemic/intra-articular corticosteroids.
