TURNER SYNDROME (TS) SURVEILLANCE GUIDELINES Screening at Diagnosis of TS in children and adults All patients Cardiovascular evaluation by specialist Renal ultrasound Hearing evaluation by an audiologist Evaluation for scoliosis/kyphosis Evaluation for knowledge of TS; referral to support groups Evaluation for growth and pubertal development Ages 0-4 yr Evaluation for hip dislocation Eye exam by pediatric ophthalmologist (if age >1) Ages 4-10 yr Thyroid function tests (T4, TSH) and celiac screen (TTG Ab) Educatinal/psychosocial evaluations Orthodontic evaluation (if age >7) Age >10 Thyroid function tests and celiac screen Educational and psychosocial evaluations Orthodontic evaluation Evaluation of ovarian function/estrogen replacement LFTs, FBG, lipids, CBC, BUN, Cr BMD (if age >18 yr) BUN, Blood urea nitrogen; CBC, complete blood count; Cr, creatinine; FBG, fasting blood glucose; LFTs, Liver function tests Ongoing Monitoring in TS All ages Cardiology evaluation as indicated Blood pressure annually ENT and audiology every 1-5 years <5 yr Social skills at age 4-5 yr School age Liver and thyroid screening annually Celiac screen every 2-5 years Educational and social progress annually Dental and orthodontic evaluations, as needed Older girls and adults Fasting lipids and blood sugar annually Liver and thyroid screening annually Celiac screen as indicated Age-appropriate evaluation of pubertal development and psychosexual adjustment
Cardiovascular Screening and Monitoring for Girls and Women with TS Screening ALL patients at time of diagnosis Evaluation by cardiologist with expertise in congenital hear disease Comprehensive exam including blood pressure in all extremities All require clear imaging of the heart, aortic valve, aortic arch and pulmonary veins Echocardiography is usually adequate for infants and young girls MRI and echo for older girls and adults EKG Follow-up monitoring depends on clinical status For patients with apparently normal cardiovascular system and age-appropriate blood pressure Reevaluation with imaging at timely occasions, e.g. at transition to adult clinic, before attempting pregnancy, or with appearance of hypertension. Girls that have had only echocardiography should undergo MRI when old enough to cooperate with the procedure Otherwise, imaging about every 5-10 years For patients with cardiovascular pathology, treatment and monitoring determined by cardiologist REFERENCE Bondy, C.
