Further Outpatient Care

Recommendations for follow-up and monitoring are summarized below [2, 24] :

  • Physical examination - Frequent until age 2 years, then yearly
  • Liver function and urine osmolality - Every year
  • Abdominal ultrasonogram - At ages 2, 5, 10, and 15 years or as indicated
  • Spirometry assessments - After age 5 years
  • Ophthalmologic examination - At ages 5 and 10 years

Further Inpatient Care

See the list below:

  • Treat postoperative ventilatory problems, and minimize secondary damage to lungs caused by prolonged ventilatory support in patients with JS.

  • Treat respiratory infections and cardiac insufficiency.



See the list below:

  • Pneumothorax

  • Mucous plugging of a bronchus

  • Repeated infections

  • Progressive herniation of lung through sternal defect

  • Cardiac insufficiency

  • Development of significant respiratory compromise after pectus excavatum repair

    • Respiratory compromise generally develops years after the original pectus operation.

    • Most patients exhibit severe growth retardation of the upper chest wall resulting in restrictive pulmonary function test results.



See the list below:

  • Prognosis is difficult to predict in each individual case because frequent pulmonary complications and cystic renal lesions are not always directly related to severity of skeletal changes.

  • JS syndrome is compatible with life, although respiratory failure and infections are often fatal during infancy.

  • The severity of thoracic constriction widely varies. For those patients who survive infancy, the thorax tends to revert to normal with improving respiratory function. This suggests that the lungs have a normal growth potential and the respiratory problems are secondary to restricted rib cage deformity.

  • Renal failure may ensue later. Renal involvement is the major prognostic factor in those patients who survive the respiratory insufficiency during infancy.

  • Survivors are short in stature.


Patient Education

Up-to-date information about the syndrome and resources is available to the families. The following websites and organizations can provide useful information:

Patients may also enroll in the UCLA International Skeletal Dysplasia Registry (ISDR).
