Pectus Excavatum, Pectus Carinatum and Poland's Syndrome PECTUS EXCAVATUM, PECTUS CARINATUM AND POLAND’S SYNDROME: SURGICAL CORRECTION BlueReview POSTED DATE: 3/23/2004 EFFECTIVE DATE: 7/1/2004 _____________________________________________________________________________ COVERAGE: Surgical repair of Pectus Excavatum and Pectus Carinatum is considered reconstructive and medically necessary if the patient meets ALL the following criteria: 1) Well documented evidence of complications arising from the sternal deformity. Complications include, but may not be limited to: a) Cardiopulmonary impairment documented by respiration and/or cardiac function tests; b) Frequent lower respiratory tract infections; c) Asthma; or d) Exercise limitations; e) Atypical chest pain; AND 2) An EKG or echocardiogram has been done if a heart murmur or known heart disease is present to define the relationship of the cardiac problem to the sternal deformity; AND 3) A CT scan of the chest demonstrates a pectus index greater that 3.25. This is derived from dividing the transverse diameter of the chest by the anterior-posterior diameter. Surgical repair of Pectus Excavatum and Pectus Carinatum is considered cosmetic if the procedure is primarily to alter appearance. Surgical repair of the deformities associated with Poland’s Syndrome is considered reconstructive and considered medically necessary. In order to determine medical necessity for the repair of Pectus Excavatum, Pectus Carinatum or deformities associated with Poland’s Syndrome, all of the following information must be provided: 1) Copies of diagnostic studies with radiologic interpretation; 2) Medical documentation describing indications for the procedure with signs and symptoms of complications arising from the sternal deformity; 3) History and physical; AND 4) Photographs of deformities. ______________________________________________________________________ DESCRIPTION: Pectus Excavatum (also known as Funnel Chest) is the most common of Blue Cross and Blue Shield of Texas, a Division of Health Care Service Corporation, a Mutual Legal Reserve Company* Southwest Texas HMO, Inc.* d/b/a HMO BlueÒ Texas * Independent Licensees of the Blue Cross and Blue Shield Association PECTUS EXCAVATUM, PECTUS CARINATUM AND POLAND’S SYNDROME: SURGICAL CORRECTION BlueReview POSTED DATE: 3/23/2004 EFFECTIVE DATE: 7/1/2004 _____________________________________________________________________________ the major congenital deformities of the sternum. This occurs when the sternum is displaced posteriorly to produce a funnel shaped depression. The degree of sternal depression is assessed on a CT scan or lateral chest X-Ray by measuring either the sternovertebral distance or a ratio of sternovertebral distance to transthoracic diameter. The etiology is not precisely understood, but overgrowth of the lower costal cartilages and ribs is thought to be responsible. The extent of the depression varies from person to person. Pectus Excavatum can cause medical complications when cardiopulmonary function is impaired. Both traditional open surgery (Ravitch repair) and newer minimally invasive techniques (Nuss repair) can be used to correct pectus excavatum. Both techniques generally improve chest appearance. They also improve rib and sternum configuration as well as cardiopulmonary (heart and lung) functioning. Both techniques result in a return to normal activity and improved exercise tolerance within the first few months following surgery. Pectus Carinatum, often called "pigeon breast," is caused when the sternum (breastbone) is pushed outward and is also a congenital deformity of the sternum. The forward protrusion of the sternum often causes pain during exercise or during times of increased respiratory effort. It increases in severity with age and generally worsens during growth spurts that occur during late childhood and adolescence. While pectus carinatum occasionally interferes with overall health, it generally does not interfere with cardiopulmonary functioning. The etiology is not precisely understood, but overgrowth of the lower costal cartilages and ribs is thought to be responsible. Surgery may be necessary to restore normal chest contour. Open surgery in boys is performed through a horizontal incision on the anterior chest well, usually just below the nipple area. In girls, this incision is placed to coincide with the lower breast margins when possible. The lower four to five cartilages that are abnormal are removed, leaving the perichondrium (the lining that envelops the outer portion of rib cartilage). This allows the cartilage to regrow in its new position. The sternum is surgically fractured and placed in the correct position. The incision is usually closed with internal sutures that minimize scarring. Poland's Syndrome is a congenital absence of the pectoralis major (chest muscle), absence or hypoplasia (underdevelopment) of the pectoralis minor, absence of costal cartilages, or hypoplasia of the breast and subcutaneous tissue. There can also be brachysyndactyly (missing fingers, missing phalanges, webbing between the fingers, one hand shorter than the other, or a combination of these deformities).

It is the severity of the medical complications and the objective results of diagnostic studies that will help determine the medical necessity for surgical repair of pectus excavatum and pectus carinatum. Poland’s syndrome is a congenital defect and patients may require reconstructive surgery to the chest wall musculature, breasts and subcutaneous tissue. _____________________________________________________________________ PRICING: None ______________________________________________________________________ REFERENCES: · Morshuis, W., Folgering, H., et al. “Exercise cardiorespiratory function before and one year after operation for pectus excavatum.” Journal of Thoracic Cardiovascular Surgery (1994) 107: 1403-1409. · Morshius, W., Folgering, H., et al. “Pulmonary function before surgery for pectus excavatum and at long term follow-up.” Chest (1994) 105(6): 1646-1652. · Fonkalsrud, W.E., Dunn, J.C., et al. “Repair of pectus excavatum deformities: 30 years of experience with 375 patients.” Annuals of Surgery.

Abstract: Poland’s syndrome (PS) is a rare musculoskeletal congenital anomaly with a wide spectrum of presentations. It is typically characterized by hypoplasia or aplasia of pectoral muscles, mammary hypoplasia and variably associated ipsilateral limb anomalies. Limb defects can vary in severity, ranging from syndactyly to phocomelia. Most cases are sporadic but familial cases with intrafamilial variability have been reported. Several theories have been proposed regarding the genesis of PS. Vascular disruption theory, “the subclavian artery supply disruption sequence” (SASDS) remains the most accepted pathogenic mechanism. Clinical presentations can vary in severity from syndactyly to phocomelia in the limbs and in the thorax, rib defects to severe chest wall anomalies with impaired lung function.

  • Spina Bifida & Certain Birth Defects
    Spina Bifida & Certain Birth Defects Spina Bifida Benefits Eligibility. (38 U.S.C. 1805) There are three basic eligibility requirements: 1. The parent(s) of a spina bifida child-claimant must have performed active military, naval, or air service in the Republic of Vietnam between January 9, 1962 and May 7, 1975. 2. The child must be the natural child of the Vietnam veteran, regardless of age or marital status, who was conceived after the date on which the veteran first entered the Republic of Vietnam. The term “natural child” means a biological child and excludes the notion of deriving entitlement from adoptive parents. Only a biological parent of an adopted child could make the child eligible. 3. Spina Bifida benefits are payable for all types of spina bifida except spina bifida occulta. Private physicians, government or private institution examination reports may establish the diagnosis. Effective Date Level I Level II Level III 12/1/2003 $237 $821 $1,402 Children of Women Vietnam Veterans Born with Certain Birth Defects (38 U.S.C. 1815) Who is eligible for the Children of Women Vietnam Veterans monthly allowance?

    Webb et al. Orphanet J Rare Dis (2021) 16:158 https://doi.org/10.1186/s13023-021-01736-1 REVIEW Open Access A framework for the evaluation of patients with congenital facial weakness Bryn D. Webb1,2* , Irini Manoli3, Elizabeth C. Engle4,5,6 and Ethylin W. Jabs1,2 Abstract There is a broad diferential for patients presenting with congenital facial weakness, and initial misdiagnosis unfortu- nately is common for this phenotypic presentation. Here we present a framework to guide evaluation of patients with congenital facial weakness disorders to enable accurate diagnosis. The core categories of causes of congenital facial weakness include: neurogenic, neuromuscular junction, myopathic, and other. This diagnostic algorithm is presented, and physical exam considerations, additional follow-up studies and/or consultations, and appropriate genetic testing are discussed in detail. This framework should enable clinical geneticists, neurologists, and other rare disease special- ists to feel prepared when encountering this patient population and guide diagnosis, genetic counseling, and clinical care. Keywords: Congenital facial weakness, Facial paralysis, Clinical genetics, Clinical characterization Clinical characteristics: congenital facial weakness CFW may be unilateral or bilateral and may be partial Congenital facial weakness (CFW) refers to decreased or complete (Fig. 2).

However, besides improving the body posture through the correction of the pectus excavatum (PE), this procedure may cause or worsen thoracic scoliosis as a result of the considerable stress loaded on the chest wall and the thorax. Our goal was to investigate the impact of the Nuss procedure on the thoracic spinal curvature in patients with PE. METHODS: A total of 100 patients with PE who underwent the Nuss procedure were included in the study and evaluated retrospectively.

  • Shprintzen-Goldberg Syndrome
    Shprintzen-Goldberg syndrome Description Shprintzen-Goldberg syndrome is a disorder that affects many parts of the body. Affected individuals have a combination of distinctive facial features and skeletal and neurological abnormalities. A common feature in people with Shprintzen-Goldberg syndrome is craniosynostosis, which is the premature fusion of certain skull bones. This early fusion prevents the skull from growing normally. Affected individuals can also have distinctive facial features, including a long, narrow head; widely spaced eyes (hypertelorism); protruding eyes ( exophthalmos); outside corners of the eyes that point downward (downslanting palpebral fissures); a high, narrow palate; a small lower jaw (micrognathia); and low-set ears that are rotated backward. People with Shprintzen-Goldberg syndrome are often said to have a marfanoid habitus, because their bodies resemble those of people with a genetic condition called Marfan syndrome. For example, they may have long, slender fingers (arachnodactyly), unusually long limbs, a sunken chest (pectus excavatum) or protruding chest (pectus carinatum), and an abnormal side-to-side curvature of the spine (scoliosis). People with Shprintzen-Goldberg syndrome can have other skeletal abnormalities, such as one or more fingers that are permanently bent (camptodactyly) and an unusually large range of joint movement (hypermobility). People with Shprintzen-Goldberg syndrome often have delayed development and mild to moderate intellectual disability. Other common features of Shprintzen-Goldberg syndrome include heart or brain abnormalities, weak muscle tone (hypotonia) in infancy, and a soft out-pouching around the belly-button (umbilical hernia) or lower abdomen (inguinal hernia). Shprintzen-Goldberg syndrome has signs and symptoms similar to those of Marfan syndrome and another genetic condition called Loeys-Dietz syndrome.

ABSTRACT Mobius syndrome is a rare condition of unclear origin, characterized by a unilateral or bilateral congenital facial weakness with impairment of ocular abduction, which is frequently associated with limb anomalies. Poland Syndrome is a rare condition that is evident at birth (congenital). Associated features may be extremely variable from case to case. However, it is classically characterized by absence (aplasia) of chest wall muscles on one side of the body (unilateral) and abnormally short, webbed fingers (symbrachydactyly) of the hand on the same side (ipsilateral). In those with the condition, there is typically unilateral absence of the pectoralis minor and the sternal or breastbone portion of the pectoralis major. In females, there may be underdevelopment or absence (aplasia) of one breast and underlying (subcutaneous) tissues. In some cases, associated skeletal abnormalities may also be present, such as underdevelopment or absence of upper ribs; elevation of the shoulder blade (Sprengel deformity); and/or shortening of the arm, with underdevelopment of the forearm bones (i.e., ulna and radius).

  • Assessment of Copy Number Variations in 120 Patients with Poland
    Vaccari et al. BMC Medical Genetics (2016) 17:89 DOI 10.1186/s12881-016-0351-x RESEARCHARTICLE Open Access Assessment of copy number variations in 120 patients with Poland syndrome Carlotta Maria Vaccari1, Elisa Tassano2, Michele Torre3, Stefania Gimelli4, Maria Teresa Divizia2, Maria Victoria Romanini5, Simone Bossi1, Ilaria Musante1, Maura Valle6, Filippo Senes7, Nunzio Catena7, Maria Francesca Bedeschi8, Anwar Baban2,10, Maria Grazia Calevo9, Massimo Acquaviva1, Margherita Lerone2, Roberto Ravazzolo1,2 and Aldamaria Puliti1,2* Abstract Background: Poland Syndrome (PS) is a rare congenital disorder presenting with agenesis/hypoplasia of the pectoralis major muscle variably associated with thoracic and/or upper limb anomalies. Most cases are sporadic, but familial recurrence, with different inheritance patterns, has been observed. The genetic etiology of PS remains unknown. Karyotyping and array-comparative genomic hybridization (CGH) analyses can identify genomic imbalances that can clarify the genetic etiology of congenital and neurodevelopmental disorders. We previously reported a chromosome 11 deletion in twin girls with pectoralis muscle hypoplasia and skeletal anomalies, and a chromosome six deletion in a patient presenting a complex phenotype that included pectoralis muscle hypoplasia. However, the contribution of genomic imbalances to PS remains largely unknown. Methods: To investigate the prevalence of chromosomal imbalances in PS, standard cytogenetic and array-CGH analyses were performed in 120 PS patients. Results: Following the application of stringent filter criteria, 14 rare copy number variations (CNVs) were identified in 14 PS patients in different regions outside known common copy number variations: seven genomic duplications and seven genomic deletions, enclosing the two previously reported PS associated chromosomal deletions. These CNVs ranged from 0.04 to 4.71 Mb in size.
