Treatment of Chronic Chest Wall Pain in a Patient With Loeys-Dietz Syndrome Using Spinal Cord Stimulation

Association between pectus excavatum and congenital genetic disorders: A systematic review and practical guide for the treating physician

BACKGROUND

Pectus excavatum (PE) could be part of a genetic disorder, which then has implications regarding comorbidity, the surgical correction of PE, and reproductive choices. However, referral of a patient presenting with PE for genetic analysis is often delayed because additional crucial clinical signs may be subtle or even missed in syndromic patients. We reviewed the literature to inventory known genetic disorders associated with PE and create a standardized protocol for clinical evaluation.

METHODS

A systematic literature search was performed in electronic databases. Genetic disorders were considered associated with PE if studies reported at least five cases with PE. Characteristics of each genetic disorder were extracted from the literature and the OMIM database in order to create a practical guide for the clinician.

RESULTS

After removal of duplicates from the initial search, 1632 citations remained. Eventually, we included 119 full text articles, representing 20 different genetic disorders. Relevant characteristics and important clinical signs of each genetic disorder were summarized providing a standardized protocol in the form of a scoring list. The most important clinical sign was a positive family history for PE and/or congenital heart defect.

CONCLUSIONS

Twenty unique genetic disorders have been found associated with PE. We have created a scoring list for the clinician that systematically evaluates crucial clinical signs, thereby facilitating decision making for referral to a clinical geneticist.

Orthopaedic Management of Loeys-Dietz Syndrome: A Systematic Review

Introduction:

Loeys-Dietz syndrome (LDS) is an autosomal dominant connective tissue disorder associated with aortic aneurysm/dissection in children. However, LDS may also present with a host of orthopaedic conditions. This study aimed to elucidate the management of orthopaedic conditions and associated outcomes in patients with LDS.

Methods:

PubMed, Ovid MEDLINE, and Cochrane Library were systematically searched for primary articles regarding the management of orthopaedic conditions in patients with LDS. The goals and findings of each included study were described. Data regarding demographics, conditions studied, treatment modalities, and outcomes were extracted and analyzed.

Results:

Three hundred sixty-two unique articles were retrieved, 13 of which were included, with 4 retrospective cohort studies and 9 case reports representing 435 patients. In total, 19.8% of patients presenting with orthopaedic conditions received surgical treatment;54.3% of them experienced adverse outcomes, and 44.4% required revision surgery. The mean age at surgery was 9.0 ± 2.1 years.

Conclusion:

Patients with LDS may require early surgical intervention for a variety of orthopaedic conditions and may be at an increased risk for surgical complications. The current LDS literature is primarily focused on spinal conditions with a relative paucity of data on the management of hip deformity, joint subluxation, clubfoot, and trauma. Additional research is required regarding orthopaedic management for this unique population.
