Terminal Transverse Defects with Orofacial Malformations (TTV-OFM) Terminal Transverse Defects with Orofacial Malformations (TTV-OFM): Case Report with Mandibular Prognathism and Submucous Cleft Palate ALVARO FIGUEROA, D.D.S SAMUEL PRUZANSKY, D.D.S. Chicago, Illinows 60680 Terminal transverse defects of varying severity, ranging from aplasia of phalanges and digits to hemimelia, have been reported in association with various orofacial malformations. Temtamy and McKusick (1978) introduced the term "terminal transverse defects with orofacial malfor- mations (TTV-OFM)" as a formal genesis syndrome (etiologically undefined) to include the following clinical entities: (1) aglossia-adac- tylia syndrome; (2) ankyloglossum (superius) syndrome; (3) Hanhart syndrome; (4) ectrodactyly with OFM; and (5) Mobius syndrome with digital malformations (including the Charlie "M" syndrome). This report describes a patient whose phenotypic characteristics qualify for inclusion under this heading, but with facial features somewhat differ- ent from those previously reported in the literature including the presence of an eccentric submucous cleft of the hard palate and zona pellucida of the soft palate.

  • Management of Fibular Hemimelia (Congenital Absence of Fibula) Using Ilizarov Method in Sulaimani
    European Scientific Journal October 2015 edition vol.11, No.30 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 MANAGEMENT OF FIBULAR HEMIMELIA (CONGENITAL ABSENCE OF FIBULA) USING ILIZAROV METHOD IN SULAIMANI Ass. Prof. Dr. Omer Ali Rafiq Barawi, Ass. Lecturer Zmnako J. Amen School of Medicine, University of Sulaimani, Kurdistan Region, Iraq Abstract Background: Fibular hemimelia is the most common congenital deficiency of long bones. Therefore, it is characterized by a wide spectrum of manifestations ranging from mild limb length inequality to sever shortening with foot and ankle deformities and associated anomalies. Objectives: To evaluate the results of ankle and foot reconstruction and limb length equalization in patients with Fibular Hemimelia. Patients and Methods: A prospective study was carried out on 40 limbs in 32 patients with fibular hemimelia during the periods of March 2010 to January 2014. Male to female ratio was 24:8. Their age ranged at an average between 2-16 years (9 years). The reconstruction of ankle and foot was done. Also, the equalization of the limb was done also using Ilizarov frame. Results: The result of this study was assessed using the Association for the Study of Applications of Methods of Ilizarov (ASAMI) scoring system. Therefore, the final results were: Failure rate with 2 limbs 5%, Poor with 2 limbs 5%, Fair with 2 limbs 5%, Good with 8 limbs 20%, and Excellent with 26 limbs 65%. Conclusion: In conclusion, the Ilizarov method is an attractive alternative method used for the management of selected fibular hemimelic patients having three or more toes who are refusing amputation.

Literature concerning their diagnosis and management in canine species is poor. Sometimes, the diagnosis and description of congenital limb abnormalities are complicated by the concurrent presence of different malformations in the same limb and the lack of widely accepted classification schemes. In order to improve the knowledge about congenital limb anomalies in dogs, this report describes the clinical and radiographic findings in four dogs affected by unusual congenital forelimb defects, underlying also the importance of reviewing current terminology.

  • Craniosynostosis Precision Panel Overview Indications Clinical Utility
    Craniosynostosis Precision Panel Overview Craniosynostosis is defined as the premature fusion of one or more cranial sutures, often resulting in abnormal head shape. It is a developmental craniofacial anomaly resulting from a primary defect of ossification (primary craniosynostosis) or, more commonly, from a failure of brain growth (secondary craniosynostosis). As well, craniosynostosis can be simple when only one suture fuses prematurely or complex/compound when there is a premature fusion of multiple sutures. Complex craniosynostosis are usually associated with other body deformities. The main morbidity risk is the elevated intracranial pressure and subsequent brain damage. When left untreated, craniosynostosis can cause serious complications such as developmental delay, facial abnormality, sensory, respiratory and neurological dysfunction, eye anomalies and psychosocial disturbances. In approximately 85% of the cases, this disease is isolated and nonsyndromic. Syndromic craniosynostosis usually present with multiorgan complications. The Igenomix Craniosynostosis Precision Panel can be used to make a directed and accurate diagnosis ultimately leading to a better management and prognosis of the disease. It provides a comprehensive analysis of the genes involved in this disease using next-generation sequencing (NGS) to fully understand the spectrum of relevant genes involved. Indications The Igenomix Craniosynostosis Precision Panel is indicated for those patients with a clinical diagnosis or suspicion with or without the following manifestations: ‐ Microcephaly ‐ Scaphocephaly (elongated head) ‐ Anterior plagiocephaly ‐ Brachycephaly ‐ Torticollis ‐ Frontal bossing Clinical Utility The clinical utility of this panel is: - The genetic and molecular confirmation for an accurate clinical diagnosis of a symptomatic patient. - Early initiation of treatment in the form surgical procedures to relieve fused sutures, midface advancement, limited phase of orthodontic treatment and combined 1 orthodontics/orthognathic surgery treatment.

  • Fibular Hemimelia Shawn C
    Parent/Patient Education Series: Fibular Hemimelia Shawn C. Standard, M.D. What Is fIbuLar hemImeLIa? Fibular hemimelia falls under the category of congenital limb deficiency. This means that a growth abnormality occurred during the development of the lower limb bud at six to eight weeks after conception. Although most of the limb abnormalities are concentrated in the lower leg and foot, the entire lower extremity is affected by this condition. The most inclusive medical term for this condition is post-axial hypoplasia of the lower limb. This means that one side of the limb bud (post-axial side – small toe side) was altered resulting in an abnormal growth pattern. hoW Common Is fIbuLar hemImeLIa? The incidence of fibular hemimelia is 1 in 40,000 live births. To put this into perspective, the United States of America usually averages about 4,000,000 live births per year. This results in 100 live births with fibular hemimelia per year in the United States. What are the ChanCes that a seCond ChILd In the same famILy WILL have thIs CondItIon? The chances of a second child having fibular hemimelia are the same as the first, 1 in 40,000. Since this genetic mutation is spontaneous, there is no increased risk of having a second child with fibular hemimelia. What are the ChanCes that a person WIth fIbuLar hemImeLIa WILL have a ChILd WIth thIs CondItIon? A person with fibular hemimelia has a 1 in 40,000 chance of having a child with fibular hemimelia. Since this genetic mutation is spontaneous, there is no increased risk of fibular hemimelia being passed down to the next generation.

  • Differential Diagnosis of Complex Conditions in Paleopathology: a Mutational Spectrum Approach by Elizabeth Lukashal a Thesis
    Differential Diagnosis of Complex Conditions in Paleopathology: A Mutational Spectrum Approach by Elizabeth Lukashal A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Master of Arts in Public Issues Anthropology Waterloo, Ontario, Canada, 2021 © Elizabeth Lukashal 2021 Author’s Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract The expression of mutations causing complex conditions varies considerably on a scale of mild to severe referred to as a mutational spectrum. Capturing a complete picture of this scale in the archaeological record through the study of human remains is limited due to a number of factors complicating the diagnosis of complex conditions. An array of potential etiologies for particular conditions, and crossover of various symptoms add an extra layer of complexity preventing paleopathologists from confidently attempting a differential diagnosis. This study attempts to address these challenges in a number of ways: 1) by providing an overview of congenital and developmental anomalies important in the identification of mild expressions related to mutations causing complex conditions; 2) by outlining diagnostic features of select anomalies used as screening tools for complex conditions in the medical field ; 3) by assessing how mild/carrier expressions of mutations and conditions with minimal skeletal impact are accounted for and used within paleopathology; and 4) by considering the potential of these mild expressions in illuminating additional diagnostic and environmental information regarding past populations.
