Cc neck pain l.jpg

CC: neck pain

  • 43 year old woman without significant PMH who presents with neck pain. She initially presented to her primary care physician in August 2007 with mild neck discomfort and feeling “like my head is too heavy for my neck.”

  • She initially thought it was from sleeping on the couch for a week but the pain persisted after she slept in her bed.

  • She was diagnosed with probable musculoskeletal strain and treated with NSAIDS and physical therapy. The pain persisted.


Hpi cont l.jpg

HPI (cont)

  • In late-October 2007 she had a sudden onset of neck swelling and trouble swallowing. She was admitted to her local hospital and started on steroids and antibiotics.

  • CT scan of the neck revealed bone destruction of C2 & C3 with ventral soft tissue swelling concerning for a mass.

  • An open biopsy was done 11/5/07 in the OR and pathology revealed only inflamed mucosa with fibrosis. This was not sent for culture.

HPI (Cont)

  • She was discharged without steroids or antibiotics and referred to UNC ENT clinic for further evaluation of her neck mass.

  • UNC ENT physician saw the patient on 10/20/07. After reviewing the CT scan from the outside hospital, the physician put the patient in a C-collar, admitted her to the hospital, called ID and neurosurgery.


Slide5 l.jpg

PMH

Discussion


A diagnostic test was performed l.jpg

“A Diagnostic test was performed…”

  • FNA and BIOPSY of ventral soft tissue mass done by ENT in the OR

    • Negative gram stain

    • No AFB seen on smear

    • Pathology - Polypoid fragments of benign squamous mucosa with parakeratosis and submucosal chronic inflammation.- No granulomatous inflammation or carcinoma identified.- AFB and GMS stains negative for AFB or fungi.

Vertebral osteomyelitis l.jpg

Vertebral Osteomyelitis

  • First described by Hippocrates and Galen

  • Prior to antibiotics was fatal in 25% of cases

  • Incidence of vertebral osteomyelitis may be increasing 2/2 increased rates of nosocomial bacteremia, increasing population age, and higher rates of IV drug use.

  • Most common site is lumbar, followed by thoracic. Cervical is rare.


Probable organisms l.jpg

Probable Organisms

  • Staph aureus is >50% of cases

    • Both HA-ORSA and CA-ORSA are making up an increasing percentage.

  • Enteric gram negative bacilli – asso w/ urinary tract instrumentation

  • Pseudomonas aeroginosa and candida are seen with catheter-related blood stream infections or IV drug use

  • Group B and G strep in pts w/ DM

  • TB


Organisms based on geography l.jpg

Organisms based on geography

  • Brucella melitensis – middle east and mediterranean

  • Burkholderia pseudomallei – periequatorial regions

  • Salmonella and entamoeba histolytica – Africa or South America


Signs and sx l.jpg

Signs and Sx

  • Neck and back pain. Usually begins insidiously and progressively worsens over weeks to months.

  • Series of 64 pts w/ spontaneous hematogenous vertebral osteo w/o h/o IV drug abuse:

    • Mean age 59

    • Mean duration of sx was 48 days prior to hospital admission

    • Neurologic impairment present in 28%

    • Blood cultures positive in 72% of cases

  • Fever inconsistent – 52% in reivew from 1979, only 30% in review from 2005


Signs l.jpg

Signs

  • Tenderness to gentle spinal percussion is the most reliable clinical sign

  • WBC may be elevated or normal, elevations in ESR and CRP present in >80% of pts

  • Diagnosis is made by bone biopsy

  • In one review article 31% of pts w/ vertebral osteo had infective endocarditis as well

    • Risk factors for IE were heart condition, heart failure, positive blood cultures, and gram positive organisms


Management l.jpg

Management

  • IV antibiotics directed at causative organism

  • Surgery indicated for

    • Progression of disease despite adequate antibiotic therapy

    • Threatened or actual cord compression due to spinal instability or vertebral collapse

    • Epidural or paravertebral abscesses


Long term outcome of 253 patients with vertebral osteomyelitis cid 2002 l.jpg

Long term outcome of 253 patients with vertebral osteomyelitis – CID 2002

  • Eleven percent of the patients died

  • Residual disability occurred in more than one-third of the survivors

  • Relapse occurred in 14%.

  • Median duration of follow-up was 6.5 years (range, 2 days to 38 years).

  • Independent risk factors for adverse outcome (death or qualified recovery) were neurologic compromise, time to diagnosis, and hospital acquisition of infection (P< or =.004).

  • Surgical treatment resulted in recovery or improvement in 86 (79%) of 109 patients.
