Health Supervision for People With Achondroplasia.

Pediatrics 2020 May 26. Epub 2020 May 26.

Department of Pediatrics, University of California, San Diego and Rady Children's Hospital, San Diego, California.

Achondroplasia is the most common short-stature skeletal dysplasia, additionally marked by rhizomelia, macrocephaly, midface hypoplasia, and normal cognition. Potential medical complications associated with achondroplasia include lower extremity long bone bowing, middle-ear dysfunction, obstructive sleep apnea, and, more rarely, cervicomedullary compression, hydrocephalus, thoracolumbar kyphosis, and central sleep apnea. This is the second revision to the original 1995 health supervision guidance from the American Academy of Pediatrics for caring for patients with achondroplasia. Read More

Pharmacokinetics and safety after once and twice a day doses of meclizine hydrochloride administered to children with achondroplasia.

PLoS One 2020 13;15(4):e0229639. Epub 2020 Apr 13.

Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine, Showa-ku, Nagoya, Aichi, Japan.

Achondroplasia (ACH) is the most common short-limbed skeletal dysplasia caused by activating mutations in the fibroblast growth factor receptor 3 (FGFR3) gene. We identified that meclizine hydrochloride inhibited FGFR3 signaling in various chondrocytic cells and promoted longitudinal bone growth in mouse model of ACH. Meclizine has safely been used for more than 50 years, but it lacks the safety data for repeated administration and pharmacokinetics (PK) when administered to children. Read More

New developments in the management of achondroplasia.

Wien Med Wochenschr 2020 Apr 6;170(5-6):104-111. Epub 2020 Mar 6.

Departments of Paediatrics and Surgery, University of Ottawa, Ottawa, Canada.

Achondroplasia is the most common form of disproportionate short stature. A dominantly inherited FGFR3 mutation permanently activates the fibroblast growth factor receptor 3 (FGFR3) and its downstream mitogen-activated protein kinase (MAPK) signalling pathway. This inhibits chondrocyte differentiation and puts a break on growth plate function, in addition to causing serious medical complications such as foramen magnum and spinal stenosis and upper airway narrowing.

Trevor's disease of the distal radioulnar joint in two children with achondroplasia.

Am J Med Genet A 2020 May 29;182(5):1249-1254. Epub 2020 Feb 29.

Department of Orthopedics and Rehabilitation, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin.

Two children with achondroplasia who developed an abnormal bony outgrowth at the distal radioulnar joint (DRUJ), indistinguishable from an osteochondroma on histology, but the radiographic appearance, location, and asymmetry suggested the rare diagnosis of dysplasia epiphysealis hemimelica (DEH or "Trevor's disease"). One child experienced symptomatic relief with surgical excision and one was observed clinically due to lack of significant symptoms. These are the first presented cases of DEH in achondroplasia, both affecting the DRUJ. Read More

Paternal age is affected by genetic abnormalities, perinatal complications and mental health of the offspring.

Biomed Rep 2020 Mar 20;12(3):83-88. Epub 2019 Dec 20.

Second Department of Gynecology, Medical University of Lublin, PL-20954 Lublin, Poland.

Infertility and fecundity problems concern 10-18% of partners in their reproductive years compromising around one million females and males in Poland. Research and analysis of factors that affect male fertility are limited, especially, regarding the age of the father and determining the age at which quality of semen decreases. Age of the father has greater impact than maternal age, on cases of sporadic autosomal dominant congenital diseases such as Apert, Crouzon, Pfeiffer, Noonan and Costello syndromes, multiple endocrine neoplasia (types 2A and 2B) and achondroplasia.

Clinical Practice Guidelines for Achondroplasia.

Clin Pediatr Endocrinol 2020 9;29(1):25-42. Epub 2020 Jan 9.

Department of Pediatrics, Osaka University Graduate School of Medicine, Osaka, Japan.

Achondroplasia (ACH) is a skeletal dysplasia that presents with limb shortening, short stature, and characteristic facial configuration. ACH is caused by mutations of the gene, leading to constantly activated FGFR3 and activation of its downstream intracellular signaling pathway. This results in the suppression of chondrocyte differentiation and proliferation, which in turn impairs endochondral ossification and causes short-limb short stature. Read More

There are virtually no data regarding appropriate oral intake in infants with dwarfing disorders such as achondroplasia, nor is there clear information regarding appropriate weight gain velocity in this population. Yet, these individuals are at increased risk for both early failure to thrive and, later in life, for obesity. Having appropriate expectations regarding weight gain and reasonable goals in management is imperative. Read More

The Phenomenon of the Apparent (Double) Femoral Head in Infant Hip Sonography According to Graf-Description, Incidence and Clinical Relevance.

Z Orthop Unfall 2019 Oct 21. Epub 2019 Oct 21.

Clinic and Polyclinic for Orthopedics and Trauma Surgery, University Hospital Bonn.

Purpose: Hip screening sonography according to Graf in rare cases yields the appearance of a double femoral head, aptly named the Double-Head-Sign. The goal of this retrospective study is to offer a definition of this rare sign, evaluate its incidence of occurrence and compare the sonographic findings with the clinical findings.

Materials And Methods: This Double-Head-Sign is caused by the overlap of the trochanter major with the actual head of the femur in cases of coxa vara. Read More

Introduction: acoustic rhinometry (AR) is a non-invasive method measuring the nasal volume (NV) and the nasal minimal cross-sectional area (MCA), reflecting nasal obstruction. The first objective of this study was to measure and compare NV and MCA between 3 groups of children: "achondroplasia", "Down syndrome" and "control". The control group corresponded to children with suspicion of sleep disorder disease and without cranio-facial malformation. Read More

Asian J Neurosurg 2019 Jul-Sep;14(3):883-885

Department of Neurosurgery, Neurosciences Centre, AIIMS, New Delhi, India.

Achondroplasia represents the common variety of skeletal dysplasia causing short-limb dwarfism. It may be associated with congenial craniovertebral junction anomaly, including atlantoaxial dislocation, Os odointoideum or basilar invagination or acquired as a result of the previous foramen magnum region surgery. However, long segment cervical compression from the first cervical vertebra region to sixth cervical region, such extensive compression producing myelopathy is not reported, and current case represents first case in the western literature.
