Emergent Cesarean Delivery in a Patient With Freeman-Sheldon Syndrome Complicated by Preeclampsia, Acute Pulmonary Embolism, and Pulmonary Edema: A Case Report.

Freeman-Sheldon syndrome (FSS) is an exceedingly rare congenital disorder with an unspecified prevalence. FSS is caused by a mutation in the embryonic skeletal muscle myosin heavy chain 3 gene. Patients may have facial abnormalities that put them at risk of difficult airway intubation. These facial abnormalities include micrognathia, macroglossia, high-arched palate, prominent forehead, and mid-face hypoplasia. Additionally, skeletal abnormalities such as joint contractures, scoliosis with resultant restrictive lung disease, and camptodactyly (bent fingers) can be noted. These features played an important role in the anesthetic management of our FSS patient. Perioperative planning and optimization were crucial in her anesthetic management as she underwent an urgent cesarean section due to preeclampsia with severe features.

Identification and Recent Approaches for Evaluation and Management of Rehabilitation Concerns for Patients with Freeman-Burian Syndrome: Principles for Global Treatment.

Freeman-Burian syndrome, formerly Freeman-Sheldon syndrome, is a rare congenital complex myopathic craniofacial syndrome that frequently involves extremity joint deformities, abnormal spinal curvatures, and chest wall mechanical problems that, together with spinal deformities, impair pulmonary function. As part of a clinical practice guideline development, we evaluated 19 rehabilitation-related articles from our formal systematic review, and from these and our experience, we describe rehabilitation considerations. Research in this area has widespread methodologic problems. While many challenges are present, much can be done to afford these patients a good quality of life through careful planning.

Epidemiology, prevention, diagnosis, treatment, and outcomes for psychosocial problems in patients and families affected by non-intellectually impairing craniofacial malformation conditions: a systematic review protocol of qualitative data.

BACKGROUND: Physical attractiveness or unattractiveness wields a tremendous impact on the social and psychological components of life. Many individuals with facial deformities are treated more negatively than normal individuals, which may affect their self-image, quality of life, self-esteem, interpersonal encounters, and ultimately, success in life. Malformations that do not create physiological problems and whose major health impact is to degrade physical attractiveness and engender psychosocial consequences are insufficiently understood and not considered functional problems by medical insurance companies. METHODS/DESIGN: As part of a clinical practice guideline development process for psychosocial concerns in Freeman-Burian syndrome, manuscripts describing psychosocial considerations related to the presence of non-intellectually impairing craniofacial malformation conditions or associated clinical activities are sought, especially focusing on epidemiology, prevention, symptoms, diagnoses, severity, timing, treatment, consequences, and outcomes. All published papers on this topic are considered in searching PubMed, OVID MEDLINE, and CINAHL Complete and again before final analyses. The results will be written descriptively to be practically useful and structured around the type or timing of psychosocial problems or consequences described or target population characteristics. No meta-analysis is planned. DISCUSSION: Because the quality of research on psychosocial problems in craniofacial malformation conditions is known to be fraught with methodological problems, inconsistencies, and considerable knowledge gaps, we anticipate difficulties, which may limit the review questions able to be answered. We hope to produce a survey relevant to all non-intellectually impaired craniofacially deformed patients and their families and outline knowledge gaps and prioritise areas for clinical investigation.

Nonoperative Orthodontic Therapy for Retrognathia and Finding of Sella Turcica Bridging in a 16-Year-Old Girl With Freeman-Burian Syndrome.

In the context of a case presentation of a 16-year-old girl treated for retrognathia associated with Freeman-Burian syndrome (FBS), importance of early orthodontic evaluation and unique problems posed by FBS are discussed. Freeman-Burian syndrome universally presents limited oral access and risk of pulmonary complications, making immaculate oral health-care arduous but mandatory. With early identification and conscientious planning, satisfactory orthodontic and overall health outcomes can be achieved. Sella turcica bridging, when presenting in FBS in the absence of endocrine pathology, may be related to the underlying myopathy of FBS.

Freeman-Burian syndrome.

CLINICAL DESCRIPTION: Freeman-Burian syndrome (FBS) is a rare congenital myopathic craniofacial syndrome. Considerable variability in severity is seen, but diagnosis requires the following: microstomia, whistling-face appearance (pursed lips), H or V-shaped chin defect, and prominent nasolabial folds. Some patients do not have limb malformations, but essentially all do, typically camptodactyly with ulnar deviation of the hand and talipes equinovarus. Neuro-cognitive function is not impaired. EPIDEMIOLOGY: Population prevalence of FBS is unknown. AETIOLOGY: Environmental and parental factors are not implicated in pathogenesis. Allelic variations in embryonic myosin heavy chain gene are associated with FBS. White fibrous tissue within histologically normal muscle fibres and complete replacement of muscle by fibrous tissue, which behaves like tendinous tissue, are observed. MANAGEMENT: Optimal care seems best achieved through a combination of early craniofacial reconstructive surgery and intensive physiotherapy for most other problems. Much of the therapeutic focus is on the areas of fibrous tissue replacement, which are either operatively released or gradually stretched with physiotherapy to reduce contractures. Operative procedures and techniques that do not account for the unique problems of the muscle and fibrous tissue replacement have poor clinical and functional outcomes. Important implications exist to facilitate patients' legitimate opportunity to meaningfully overcome functional limitations and become well.

Findings, phenotypes, and outcomes in Freeman-Sheldon and Sheldon-Hall syndromes and distal arthrogryposis types 1 and 3: protocol for systematic review and patient-level data meta-analysis.

BACKGROUND: Freeman-Sheldon and Sheldon-Hall syndromes (FSS and SHS) and distal arthrogryposis types 1 and 3 (DA1 and DA3) are rare, often confused, congenital syndromes. Few studies exist. With reported diagnosis unreliable, it would be scientifically inappropriate to consider articles describing FSS, SHS, DA1, or DA3, unless diagnoses were independently verified, rendering conventional systematic review and meta-analysis methodology inappropriate and necessitating patient-level data analysis (PROSPERO: CRD42015024740). METHODS/DESIGN: As part of a clinical practise guideline development process, we evaluate (1) diagnostic accuracy from 1938-2017, using the Stevenson criteria; (2) the most common physical findings, possible frequency clusters, and complications of physical findings amongst patients with FSS; and (3) treatment types and outcomes. All papers reporting diagnosis of FSS, SHS, DA1, and DA3 are included in searching PubMed and Google Scholar from December 2014 to July 2015 and again before final analyses. Patients with FSS are divided into four phenotype-defined sub-types; all patients are grouped by published diagnosis and medical speciality. Significance of physical findings and historical data is evaluated by chi-square. Associations of physical findings and history with diagnosis and treatment outcome are evaluated by Pearson correlation and linear regression analysis. Two-tailed alpha level of 0.05 is used throughout. DISCUSSION: The need for detailed patient-level data extraction may limit the types of articles included and questions able to be answered. For treatment and psychosocial health outcomes, we anticipate enhanced difficulties, which may limit significance, power, and results' usability. We hope to outline knowledge gaps and prioritise areas for clinical investigation. SYSTEMATIC REVIEW REGISTRATION NUMBER: CRD42015024740 Universal Trial Number: U1111-1172-4670.

Molecularly proven mosaicism in phenotypically normal parent of a girl with Freeman-Sheldon Syndrome caused by a pathogenic MYH3 mutation.

We report a case of a female child who has classical Freeman-Sheldon syndrome (FSS) associated with a previously reported recurrent pathogenic heterozygous missense mutation, c.2015G > A, p. (Arg672His), in MYH3 where the phenotypically normal mother is a molecularly confirmed mosaic. To the best of our knowledge, this is the first report in the medical literature of molecularly confirmed parental mosaicism for a MYH3 mutation causing FSS. Since proven somatic mosaicism after having an affected child is consistent with gonadal mosaicism, a significantly increased recurrence risk is advised. Parental testing is thus essential for accurate risk assessment for future pregnancies and the use of new technologies with next generation sequencing (NGS) may improve the detection rate of mosaicism. © 2016 Wiley Periodicals, Inc.

Consanguineous Marital Union Resulting in a Progeny of Whistling-face Syndrome and Hemophilia: A Case Report.

Many different types of genetic disorders are noted to be prevalent among consanguineous progeny. Although the most common type of consanguineous union in all major societies is between first cousins, the importance of customary influences is apparent from variations in the specific types of first-cousin marriages contracted. Epidemiological data for the prevalence of whistling-face syndrome (WFS) are not available, but less than a hundred cases reported in the literature are noted. We are presenting a case where a consanguineous marriage resulted in two of their children presenting with WFS and one with hemophilia.

A Case of Freeman-Sheldon Syndrome

PURPOSE: To report a patient with Freeman-Sheldon syndrome with blepharophimosis. METHODS: A 4-year-old girl with congenital facial abnormalities consistent with Freeman-Sheldon syndrome presented with complaints of blepharophimosis. The characteristic features of microstomia, down-slanting palpebral fissure, blepharoptosis, and telecanthus were also found. Y-V epicanthoplasty and levator aponeurosis resection were performed. RESULTS: Surgical intervention to correct ptosis and telecanthus led to initially fair cosmetic results, but one month later an unexpected decrease in interpalpebral fissure height was noted. CONCLUSIONS: Freeman-Sheldon syndrome with blepharophimosis is very rare. It was necessary to correct blepharoptosis, telecanthus, and blepharophimosis in the oculoplastic service in this case.

A Case of Freeman-Sheldon Syndrome in Father and Son

Freeman-Sheldon syndrome is a rare syndrome first described by Freeman and Sheldon in 1938. Features of the syndrome include a characteristic facial appearance with multiple skeletal anomalies due to abnormal muscle tone. Since its first description, the syndrome has been called the Freeman-Sheldon syndrome, Windmill-Vane-Hand syndrome and Whistling-Face syndrome. The diagnosis may be made clinically during the first year of life. The majority of reported cases of Freeman-Sheldon syndrome are autosomal dominantly inherited but a clinically indistinguishable autosomal recessive type has been reported. We experienced a case of Freeman-Sheldon syndrome in a newborn who presented with prominent supraorbital ridge, sunken eyes, telecanthus, short nose, long philtrum, and marked microstomia. The neck was short. The hands showed symmetrically clenched fingers with camptodactyly and feet demonstrated bilateral talipes equinovarus. His father has a slight microstomia and contractures of both fingers.
