DIAGNOSIS
SIGNS AND SYMPTOMS
  • Intermittent painful spasms of sternocleidomastoid (SCM), trapezius, and other neck muscles
  • Head is rotated and twisted to 1 direction
  • Pure flexion (anterocollis) or extension (retrocollis) is
    rare:
    • Represents symmetric involvement of muscles
  • Symptoms usually aggravated by standing, walking, or stressful situations
  • Usually does not occur with sleep
History
  • Obtain a complete medication history
  • The majority of antipsychotic medication–induced dystonic reactions occur between 12 and 23 hr
  • Obtain a complete trauma history
Physical-Exam
  • Head is rotated and twisted to 1 direction
  • Neck movements vary from jerking to smooth
  • The presence of fever supports an infectious or inflammatory etiology
  • If the neurologic exam is focal, consider spinal cord or CNS disease
  • Congenital form:
    • A firm, nontender enlargement of the SCM muscle visible at birth
ESSENTIAL WORKUP
  • Geared toward diagnosing life-threatening etiologies above
  • Distinguish torticollis from other causes of neck stiffness (meningismus)
  • Cervical spine films to evaluate for fracture except patients with chronic paroxysmal episodes
DIAGNOSIS TESTS & NTERPRETATION
Lab

No specific tests helpful

Imaging
  • CT or MRI of cervical spine if retropharyngeal abscess or tumor suspected
  • High-frequency and color Doppler ultrasonography is the test of choice for congenital muscular torticollis
  • Plain films, lateral and AP view for acquired torticollis resulting from trauma
  • CT scan of the neck or cervical spine in nontraumatic acquired torticollis
Diagnostic Procedures/Surgery
  • Consider administering an anticholinergic medication if drug-induced etiology is suspected
  • Consider performing the Tensilon test if myasthenia gravis is a consideration
DIFFERENTIAL DIAGNOSIS
  • CNS infections
  • Tumors of soft tissue or bone
  • Basal ganglia disease
  • Abscess of cervical glands
  • Myositis of cervical muscles
  • Cervical disk lesions
  • Myasthenia gravis
TREATMENT
PRE HOSPITAL
  • Ensure patent airway
  • Cervical spine precautions for any history of trauma
  • Support head
INITIAL STABILIZATION/THERAPY

Cervical spine immobilization if fracture is suspected

ED TREATMENT/PROCEDURES
  • Drug (e.g., phenothiazine) induced:
    • Diphenhydramine or benztropine
  • Acquired:
    • Soft collar and rest
    • Physical therapy
    • Massage
    • Local heat
    • Analgesics
MEDICATION
  • Benztropine (for drug-related dystonia): 1–2 mg IM or slow IV, followed by 3–5 days PO
  • Clonazepam (2nd-line drug): 0.5 mg PO TID
  • Diphenhydramine (for drug-related dystonia): 25–50 mg IV or IM followed by 3–5 days PO q6–8h; (peds: 5 mg/kg/24 h div. q6h IV, IM, or PO)
  • Trihexyphenidyl (a 1st-line drug): 2–5 mg/d PO, advance to 30 mg/d
  • Valium: 2–5 mg IV, 2–10 mg PO TID (peds: 0.1–0.2 mg/kg/dose IV or PO q6h)
  • Botulinum toxin is the 1st-line agent for treating nondrug-induced torticollis, though this is not typically administered in the ED setting
FOLLOW-UP
DISPOSITION
Admission Criteria
  • Cervical spine fracture
  • Diagnosis in doubt
  • Infectious causes
  • Toxic appearance
  • Inability to maintain adequate fluid intake
  • Lack of support system
Issues for Referral

Some patients who fail medical treatment may benefit from surgical treatment, such as accessory nerve ablation or deep brain stimulation

FOLLOW-UP RECOMMENDATIONS
  • Outpatient referral to an orthopedist, neurologist, or neurosurgeon who uses botulinum toxin in his or her practice
  • Physical therapy and consider chiropractic care
  • Return to ED for weakness or worsening symptoms
PEARLS AND PITFALLS

Exclude infectious, inflammatory, traumatic, spinal cord and CNS causes of torticollis.

TOXIC EPIDERMAL NECROLYSIS
Andrew K. Chang

Andrew E. Chertoff
BASICS
DESCRIPTION
  • One of the most fulminant and potentially fatal of all dermatologic disorders
  • Skin sloughing at the dermal–epidermal interface results in the equivalent of a 2nd-degree burn
  • Can affect up to 100% of total body surface area (BSA)
  • May extend to involve:
    • GI mucosa
    • Respiratory mucosa
    • Genitourinary/renal epithelium
  • Mechanism unclear, research indicates immunologic, cytotoxic, and delayed hypersensitivity may be involved as well as genetic susceptibility
  • Current classification system proposes 3 categories within the spectrum of Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), distinct from erythema multiforme major and based on percentage of total BSA:
    • SJS: <10% of BSA
    • SJS–TEN overlap syndrome: 10–30% of BSA
    • TEN: >30% of BSA, can affect up to 100% BSA
  • More common in older patients and immunocompromised patients
  • Mortality rate is about 30%, usually due to secondary sepsis from
    Staphylococcus aureus
    and
    Pseudomonas aeruginosa
  • Synonym(s):
    • Lyell syndrome
    • Fixed drug necrolysis
    • Epidermolysis necroticans combustiformis
    • Epidermolysis bullosa
