Airway management in Escobar syndrome: A formidable challenge

Escobar syndrome, difficult airway management in pediatrics: A case report

Escobar syndrome is a rare, autosomal recessive disease of unknown incidence. It is characterized by multiple skeletal, genitourinary and orofacial abnormalities. The multiple malformations (mainly orofacial) and restricted mobility of these patients pose a challenge to the anesthesia team, especially as regards airway management. We describe the clinical case of a pediatric patient diagnosed with Escobar syndrome who underwent two consecutive anesthesia interventions, with evidence of progressive airway anomalies that characterize this syndrome.  The case required adaptation, according to the clinical stage of the disease, of the current algorithms used to approach an anticipated difficult airway in pediatrics,  and  the incorporation of new devices, not described so far in patients with this pathology, as part of the planning and execution phases.

Growth-Friendly Spine Surgery in Escobar Syndrome

BACKGROUND

The aims of this study were to characterize the spinal deformity of patients with Escobar syndrome, describe results of growth-friendly treatments, and compare these results with those of an idiopathic early-onset scoliosis (EOS) cohort to determine whether the axial stiffness in Escobar syndrome limited correction.

METHODS

We used 2 multicenter databases to review the records of 8 patients with EOS associated with Escobar syndrome who had at least 2-year follow-up after initiation of growth-friendly treatment from 1990 to 2016. An idiopathic EOS cohort of 16 patients matched for age at surgery (±1 y), postoperative follow-up (±1 y), and initial curve magnitude (±10 degrees) was identified. A randomized 1:2 matching algorithm was applied (α=0.05).

RESULTS

In the Escobar group, spinal deformity involved 7 to 13 vertebrae and ranged from no vertebral anomalies in 3 patients to multiple segmentation defects in 6 patients. Mean age at first surgery was 5 years (range, 1.4 to 7.8 y) with a mean follow-up of 7.5 years (range, 4.0 to 10 y). Mean major curve improved from 76 degrees at initial presentation, to 43 degrees at first instrumentation, to 37 degrees at final follow-up (both P<0.001). Mean pelvic obliquity improved from 16 degrees (range, 5 to 31 degrees) preoperatively to 4 degrees (range, 0 to 8 degrees) at final follow-up (P=0.005). There were no differences in the mean percentage of major curve correction between the idiopathic EOS and Escobar groups at the immediate postoperative visit (P=0.743) or final follow-up (P=0.511). There were no differences between the cohorts in T1-S1 height at initial presentation (P=0.129) or in growth per month (P=0.211).

CONCLUSIONS

Multiple congenital fusions and spinal curve deformity are common in Escobar syndrome. Despite large areas of congenital fusion, growth-friendly constructs facilitate spinal growth and improve curve correction. These results are comparable to those in idiopathic EOS.

Level III-case-control study.

Multiple pterygium syndrome: Challenge for anesthesiologist

Multiple pterygium syndrome (MPS) is a very rare autosomal recessive disorder characterized by flexion of joint and digit contractures, skin webbing, cleft palate, deformity of the spine, and cervical spine fusion. Difficult airway is associated mainly due to micrognathia, retrognathia, webbing of the neck, and limitation of the mouth opening and neck extension. We are reporting a case of a 5-year-old female diagnosed with MPS and exhibiting a bilateral club foot and congenital vertical talus. The patient was posted for manipulation and above the knee casting under general anesthesia.
