Multiple Hereditary Exostoses
Multiple Hereditary Exostoses Dror Paley MD, FRCSC Medical Director, Paley Orthopedic and spine Institute, St. Mary’s Medical Center, West palm Beach, FL David Feldman, MD Director, Spinal deformity center, Paley Orthopedic and spine Institute, St. Mary’s Medical Center, West palm Beach, FL Multiple hereditary exostoses (MHE), also known as multiple osteochondromas (MO), is an autosomal dominant skeletal disorder. Approximately 10–20% of individuals are a result of a spontaneous mutation while the rest are familial. The prevalence of MHE/MO is 1/50 000. There are two known genes found to cause MHE/MO, EXT1 located on chromosome 8q23-q24 and EXT2 located on chromosome 11p11-p12. In 10–15% of the patients, no mutation can be located by current methods of genetic testing.1–7 These mutations are scattered across both genes. EXT1/EXT2 is essential for the biosynthesis of heparan sulfate (HS). HS production in patients’ cells is reduced by 50% or more.8–19 MHE/MO is associated with characteristic progressive skeletal deformities of the extremities and shortening of one or both the sides, leading to limb length discrepancy (LLD) and short stature.20–28 Two bone segments, such as the lower leg or forearm, are at greater risk of problems due to either osteochondromas (OCs) from one or both bones impinging on or deforming the other bone or a primary issue of altered growth causing one bone to grow at a faster or slower rate. OCs can also affect joint motion due to impingement of an OC with the opposite side of the joint or subluxation/dislocation related to deformity, impingement, and incongruity.20,24,26,29,30 OCs can also cause nerve or vessel entrapment and/or compression, including the spinal cord and nerve roots. -

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. -

Serum creatine kinase may be normal or elevated. Heterogeneity in presenting symptoms can occur even amongst affected members of the same family. Congenital myopathies can be divided into three main clinicopathological defined categories: nemaline myopathy, core myopathy and centronuclear myopathy (2). Nemaline Myopathy Nemaline Myopathy is characterized by weakness, hypotonia and depressed or absent deep tendon reflexes. Weakness is typically proximal, diffuse or selective, with or without facial weakness and the diagnostic hallmark is the presence of distinct rod-like inclusions in the sarcoplasm of skeletal muscle fibers (3). Core Myopathy Core Myopathy is characterized by areas lacking histochemical oxidative and glycolytic enzymatic activity on histopathological exam (2). Symptoms include proximal muscle weakness with onset either congenitally or in early childhood. Bulbar and facial weakness may also be present. Patients with core myopathy are typically subclassified as either having central core disease or multiminicore disease. Centronuclear Myopathy Centronuclear Myopathy (CNM) is a rare muscle disease associated with non-progressive or slowly progressive muscle weakness that can develop from infancy to adulthood (4, 5). -

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. -
Recurrent Pregnancy Loss Precision Panel Overview Indications Clinical
Recurrent Pregnancy Loss Precision Panel Overview Recurrent Pregnancy Loss (RPL) is one of the most common obstetric complications, affecting more than 30% of conceptions. These can occur during preimplantation, pre-embryonic, embryonic, early fetal, late fetal and stillbirth. An important number of losses are due to genetic abnormalities, nonetheless 50% of early pregnancy losses have been associated with chromosomal abnormalities. The majority are due to de novo non-disjunctional events during meiosis and balanced paternal translocations. Traditionally, the assessment of recurrent pregnancy loss was based on karyotyping techniques. However, advances in molecular genetic technology have provided an array of information regarding genetic causes and risk factors for pregnancy loss. One of the most innovative techniques with a significant role in RPL is preimplantation genetic testing in in vitro fertilization cycles. The Igenomix Recurrent Pregnancy Loss Precision Panel can be used to make a directed and accurate differential diagnosis of inability to carry out a full pregnancy ultimately leading to a better management and achieve a healthy baby at home. 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 Recurrent Pregnancy Loss Precision Panel is indicated for those patients the following manifestations: - Inability to conceive after 1 year of unprotected intercourse - Family history of infertility - Personal history of recurrent miscarriages - Family history of recurrent miscarriages - Previous failed IVF cycles - Other failed assisted reproductive technology (ART) treatments Clinical Utility The clinical utility of this panel is: - The genetic and molecular confirmation for an accurate clinical diagnosis of a symptomatic patient.
