Focused Physical Assessment

It is important to identify infants of affected women as high-risk infants. Scrutinize the maternal history and, when possible, determine the specific EDS type of the mother or affected family members. Although there may be variations in presentation, the type will remain consistent and may be useful in predicting risk. Early evaluation of an infant exhibiting major or minor criteria of EDS ( Table 2 ) is a priority. Delivery room resuscitation and respiratory support may be necessary due to prematurity and/or hypotonia.

Compare the infant's overall tone and appearance to expectations appropriate for the infant's gestational age. Infants with classical-type EDS present with intrauterine growth restriction and/or prematurity.^[9,34] The infant's general appearance may be similar to that of the infant with classic asymmetrical intrauterine growth restriction, including a normal occipital-frontal head circumference and a body that appears wasted by comparison (Fig 1). In contrast, infants affected with kyphoscoliosis-type EDS have a Marfan-like appearance, where the limbs are disproportionately longer than the rest of the body.^[36]

Examine the quality of the skin. Infants with classical and hypermobile EDS have skin that feels soft and velvet-like, a feature that is lifelong. The skin texture has also been described as doughy.^[1,2,7,10] Note the presence, and pattern of distribution of ecchymosis. Dermatosparaxis-type EDS, presents with severe skin fragility and bruising.^[1,4,39] Ongoing bruising and skin tears can be misdiagnosed as child abuse.^[6]

Both classical and vascular types of EDS are characterized by translucent skin with prominent veins.^[1] Relate these findings to norms for gestational age. In vascular-type EDS, veins are clearly visible on the thorax, shoulders, and abdomen.^[9,26,27,28] Although the skin is fragile and bruises easily with both types, coagulation studies will be normal.^[1,26] Observe for signs of acrogeria (the appearance of aging) on the hands and feet. In vascular-type EDS, the hands and feet may appear wrinkled and old.^[1,26,28]

Observe for skin that splits easily, a finding common in classical- and hypermobility-type EDS. Gaping "fish mouth" type scars may occur over bony prominences. Inspect the forehead, chin, elbows, or knees for scarring.^[1] The bruising and scarring will become more noticeable as the infant ages and becomes mobile. There are often severe scars, called cigarette paper scars, which resemble papyrus paper (Fig 2).^[1,10,16,25] Slow wound healing with scars that widen after healing can be seen during the toddler years (Fig 3).^[41] Palpate pressure points for mulluscoid pseudotumors, fleshy lesions associated with scars that develop over the pressure points (e.g., shins).^[1,3,6,10]

Inspect and palpate for piezogenic papules, which can be seen in classical-type EDS as early as birth. Piezogenic papules are small, soft lumps that appear on the side of the heel when the person is standing but which disappear when the foot is elevated.^[1,10] Small, mobile, spherical hard bodies are palpable and may be present on the forearms or shins.^[1,2,5,6] These can calcify and be visible on radiographs.^[5,10] Spheroids develop over time as subcutaneous fat necrosis occurs.^[44]

The skin of an infant with classical-type EDS has hyperextensible or hyperelastic properties not seen as a manifestation of vascular-type EDS.^[1,26] To accurately assess for hyperextensible skin, test the skin in a neutral site such as the palm side of the forearm.^[1,10] Pull the skin up until resistance is felt. Hyperextensible skin extends easily and snaps back after releasing it. Hyperelasticity is more easily noted at the neck, elbows, or knees (Fig 4).^[1] This is in contrast to the presentation of cutis laxa, where the skin lacks elasticity, hangs in loose folds, and does not rebound rapidly after extended.^[10] This test may be difficult to perform in newborns because subcutaneous fat may impair the assessment.

The infant with vascular-type EDS has distinctive facial features. Observe for bulging eyes with telangiectasis (dilated capillaries forming a red lesion) on the eyelids.^[1,25,26,30] Examine the infant for epicanthal folds (redundant skin folds on the eyelids)^[1,41] that may make the nose appear broad.^[28] Facial bones may be prominent with sunken cheeks as well as thin, fine upper lips that are unpuckered in appearance.^[26] The infant with kyphoscoliosis-type EDS will have scleral fragility. Minor trauma can cause rupture of the ocular globe.^[1,35] Examine the size of the eyes, specifically evaluating for small corneas.^[1,35,36] Inspect the nose for a proportionately large and thin "pinched" appearance.^[26] Inspect the scalp hair distribution, which may be thin in affected infants. Inspect and palpate the earlobes; lobeless ears may be present in infants with vascular-type EDS.^[31,41]

Auscultate the lung fields and observe for signs of respiratory distress, such as nasal flaring, grunting, retractions, or decreased air exchange that may indicate a pneumothorax. Newborns with vascular-type EDS are at risk of developing a spontaneous pneumothorax.^[28] If a murmur is present in the newborn period, a pediatric cardiology consultation and an echocardiogram are indicated to evaluate for dysplastic valves (mitral and tricuspid), a dilated aorta or pulmonary trunk, or heart failure.^[45]

Aortic root dilation has been reported in classical and hypermobile types of EDS in children <15 years old.^[19] These cardiac findings were in contrast to former studies where mitral valve prolapse was the most common cardiac finding in EDS.^[19] In the absence of cardiac symptoms or a murmur, at a minimum, the aortic root size should be measured by 5 years of age with repeat echocardiograms every 5 years even if the original echocardiogram is normal.^[35]

Inspect the abdomen and groin for inguinal hernias or a large umbilical hernia.^[1,39] Palpate the abdomen and bladder. Observe for lower abdominal tenderness. If possible, observe the strength of the urinary stream, especially in male infants. A weak urinary stream despite a full bladder associated with tenderness may warrant further investigation. Male children with EDS are at increased risk of giant bladder diverticula, which may cause urethral obstruction.^[17]

Examine the feet for talipes equinovarus (clubfoot).^[1] Up to 12% of neonates born with vascular-type EDS have a clubfoot and 3% have congenital dislocation of the hips.^[26,28,39] Joint hyperlaxity dislocatabilty is a common feature of EDS (Figs 5 and 6).^[1,10] Evaluate the infant's overall tone and posture. Assess the joints for stability using Beighton's criteria ( Table 3 ). A score of at least 5 out of 9 defines hypermobility.^[1,2,10] Be alert for dislocated hips or shoulders, which may be associated with breech presentation and delivery in infants affected with classical-type EDS.^[10,38]

Kyphoscoliosis-type EDS presents with joint laxity and severe muscle hypotonia at birth.^[1,4,35,38] Examine the spine carefully. Kyphoscoliosis, characterized by progressive deformity of the spine consisting of lateral and posterior curvatures, is present at birth and progressively worsens.^[35,38]

Sidebar 1: Putting a Face to Vascular Type EDS: A Mother's Story. By: Cathy Bowen

Editor's Note
The following story illustrates the importance of both taking a complete family history, and of really listening to the details of the story. David's pictures (Figs 7A-F) illustrate the changing face of EDS. David's history, as recounted by his mother, also provides some very important clues to the diagnosis of EDS. We thank this mother for her insights, and we heed her important reminder to look and listen ever so carefully to our patients and their parents.MBF

David Daniel Bowen III was born March 31, 1982 after my water broke prematurely and I went into labor at 36 weeks gestation. He weighed 4 lbs 5 oz (1956 grams), was 17 ½ inches long, and his head measured 12 ¾ inches. The doctors evaluated David and decided that because of his head size he was actually small for gestational age and closer to 39 weeks. David was born with thin, translucent skin on his chest and abdomen that persisted throughout his life. He had bilateral inguinal hernias, cryptorchidism, bilateral hydroceles, and hypospadias. His hips were also rotated inward at birth later causing him to toe-in when he learned to walk. David also had a small mouth with a high arched palate, cross bite, and crowded teeth.

David was active in all sports; he especially loved hockey, karate, and basketball. However, he seemed to have a propensity for injuries. He had stitches in his scalp that would not hold. A dog bite under his right eye took 40 internal and external stitches. This wound healed without problems. Later an elbow wound developed into a deep cigarette paper scar. When he was 10 years old he tore his anterior cruciate ligament and had to wear a knee brace.

David had bowel problems. He could only stool every 2 to 3 days and would pass blood and mucous with large formed stools. At 13 ½ years of age he had a spontaneous sigmoid colon rupture and developed peritonitis and marked inflammation of the small bowel. This required a colostomy repair. His surgeon said this perforation was unusual; he had not seen it before and he did not understand the cause. Unfortunately, because of the perforation, the surgeon raised the question of abuse and a social worker conducted a child abuse investigation. Needless to say, no evidence was found. Although 5 different physicians were consulted no one gave David a diagnosis; he was treated like a normal healthy boy.

David recovered slowly after his surgery. On his eighth postoperative day when the intern was removing the staples from his incision, the skin spread apart and bled like a fresh wound. They placed adhesive strips on the wound edges and David was discharged home a day later. Postoperatively, David returned to the surgeon's office 3 times in the first 2 weeks because of complaints of extreme gas pain, loss of appetite, weight loss, pain under his right rib area, a pulling sensation, and right lower chest discomfort that interfered with taking a deep breath. The 5.5-inch vertical incision spread to 1.5 inches wide, and required recurrent cauterization to the wound edges. It took a long time to heal; however, these symptoms were not recognized as atypical. Four months later, David returned to surgery for an end-to-end reanastomosis that was complicated by multiple adhesions. The reanastomosis failed; David developed septic shock and was transferred to another facility for emergency surgery. On July 8, 1996, David died.

Shortly before his death David was first examined by a geneticist. She felt that he had a connective tissue disorder called Ehlers-Danlos syndrome type IV (now reclassified to EDS vascular type). David had a skin biopsy done confirming that this was a spontaneous "new" mutation of vascular-type EDS.

We remain completely devastated by David's loss even years later. Every day remains a struggle. No one can fathom the magnitude of these feelings unless they have lost a child this way. Our family tries to use our grief for David in a positive way, to bring education and awareness to others. Our hope is that we can prevent another family from having to endure what happened to us.
