• Etymology and Definition

  • The name "torticollis" comes from the Latin words "tortus" (twisted) and "collum" (neck).
  • Torticollis typically involves the head being tilted to one side and rotated so that the chin points to the opposite side.
  • It is a common manifestation of cervical dystonia in adults.

• Clinical features

  • First recognized in 1969 by Snyder, who described 12 affected children.
  • Onset typically occurs between 2 and 8 months of age.
  • Recurrent attacks of torticollis last from 10 minutes to 14 days, most often 2-3 days.
  • Head turn can be to either side.
  • Frequency: 2-3 attacks per month, with children being normal between episodes.
  • Seven of the 12 children experienced symptoms like vomiting, pallor, and agitation at the onset of attacks; the other five appeared content unless their head position was forcibly corrected.
  • Episodes generally stopped spontaneously by 2-3 years of age, with variation:
    • One child: episodes stopped at 10 months.
    • Another: episodes ceased at 5 years of age.
  • Older children sometimes reported the sensation that the "house was turning," and ataxia was noted in four children during episodes.
  • EEG and neuroimaging studies are typically normal in BPTI cases.

• Snyder’s Findings and Subsequent Research

  • Snyder performed caloric testing, which indicated labyrinthine dysfunction as a possible underlying cause.
  • Subsequent studies noted additional features, such as:
    • Lateral curvature of the trunk and retrocollis (Chutorian, 1974).
    • Affected siblings (Lipson and Robertson, 1978).
    • Regular occurrence with predictable timing (Sanner and Bergström, 1979).
    • Female predominance and early morning onset (Hanukoglu et al., 1984).
    • Drigo et al. (2000) observed that:
      • Episodes occurred on awakening in only half of the cases.
      • Only 27.3% of cases had head turn to the same side consistently.
      • Half of the children had tortipelvis.
      • They described a subset of episodes similar to Cataltepe and Barron's (1993) descriptions, characterized by sudden onset with head and eye turning, rapid blinking, flexing of upper limbs, and tears.
  • Drigo et al. (2000) proposed two forms of BPTI:
    • Periodic torticollis lasting several hours or days.
    • Paroxysmal form lasting only minutes, with ocular signs.

• Rosman et al. (2009) Study

  • Reviewed 103 cases from literature and described ten personal cases.
  • Found that:
    • Five of the ten children had gross motor delay, and three had fine motor problems.
    • Symptomatic treatment was generally ineffective.
    • Caloric and audiometric testing were normal in most cases.

• Treatment

  • Yaghini et al. (2016) noted four children responding well to topiramate.

• Diagnostic and Differential Diagnosis

  • Kimura and Nezu (1998) suggested BPTI is a dystonic phenomenon.
  • BPTI is considered an early manifestation of migraine or part of periodic syndromes of childhood.
  • Differential diagnosis includes:
    • Seizures, vertigo, gastroesophageal reflux, Sandifer syndrome.
    • Dystonic reaction to drugs, ocular abnormalities (e.g., fourth cranial nerve palsies).
    • Posterior fossa and craniocervical junction abnormalities (e.g., atlanto-axial instability, Arnold-Chiari malformation, posterior fossa tumors).

• Genetic Studies and Findings

  • Drigo et al. (2000) suggested a possible channelopathy.
  • Giffin et al. (2002) reported a father and son with BPTI and CACNA1A gene mutations.
  • Cuenca-León et al. (2008) described a patient with BPTI and CACNA1A mutation who later developed other conditions.
  • Roubertie et al. (2008) reported a family with various presentations including BPTI and CACNA1A mutations.
  • Vila-Pueyo et al. (2014) noted BPTI with loss of function mutations in the CACNA1A gene.
  • Dale et al. (2012) described a child with BPTI and PRRT2 mutation who later developed infantile seizures.

• Conclusion

  • BPTI is a clinical syndrome with diverse manifestations and multiple etiologies.
  • Careful assessment is required due to the wide variety of presentations and potential underlying causes.
