Clinically Significant Fracture Incidence in Czech Children: A Population-based Study

Soucek Ondrej , Lebl Jan , Sumnik Zdenek

Background: Before reaching adulthood, every second boy and every third girl will sustain a fracture. This growth spurt-related bone fragility is partially caused by a quick longitudinal growth and a relatively slower increase in bone width. However, no study has focused particularly on clinically significant fractures, a criterion for osteoporosis diagnostics.Objective and hypotheses: The aim of this study was to describe the incidence of clinically sig...

Lithium Chloride Prevents Glucocorticoid-Induced Growth Failure in Cultured Foetal Rat Metatarsal Bones

Soucek Ondrej , Zaman Farasat , Savendahl Lars

Background: Glucocorticoids (GCs) are frequently used to treat numerous chronic diseases in children. Beside their desired anti-inflammatory and immunosuppressive effects, GCs are well known to cause osteoporosis and impaired linear bone growth. These serious side effects of GCs have at least partially been linked to impairment of Wnt/β-catenin signalling. There is no therapy available to rescue from the undesired skeletal effects of GCs.Objective a...

Decreased Trabecular Bone Mineral Density and Muscle Area at the Forearm Despite Improvement in Glycaemic Control Over 3 Years After Simultaneous Pancreas Kidney Transplantation

Soucek Ondrej , Maratova Klara , Sumnik Zdenek , Brunova Jana , Kratochvilova Simona

Background: Simultaneous pancreas kidney transplantation (SPKT) is a standard treatment option for young adults with type I diabetes (T1D) and concurrent renal failure. Despite the long-term immunosuppressive therapy the patients have better glycemic control, normalized renal function and an improved quality of life. Whether this is also reflected in the skeleton is not that clear yet.Methods: Patients were prospectively...

The Validation of an Automated Bone Age Assessment in Girls with Turner Syndrome – A Pilot Study

Soucek Ondrej , Lebl Jan , Maratova Klara , Zemkova Dana , Sumnik Zdenek

Background: Bone age evaluation is a basic tool to manage the treatment of girls with Turner syndrome (TS). The current standard of care is to involve an experienced medical staff to use the Tanner Whitehouse 3 (TW3) or Greulich-Pyle (GP) method for manual evaluation of the bone age. As this is time consuming and may be partially influenced by the evaluator’s skills, automated systems may prove more efficient.Objective and hypothesis: The aim of thi...

Fracture Incidence is Not Associated with the Six-Year Development of Trabecular BMD in Paediatric Turner Syndrome Patients

Soucek Ondrej , Sumnik Zdenek , Snajderova Marta , Kolouskova Stanislava , Lebl Jan

Background: Increased fracture risk and decreased bone mineral density (BMD) have been demonstrated by several studies in Turner syndrome (TS). However, longitudinal data on BMD development in childhood and adolescence and a reliable densitometric predictor of fractures in TS are still lacking.Objective and hypotheses: Our aim was to longitudinally assess BMD in paediatric TS patients and test whether trabecular BMD development over six years of observat...

Bone mineral density development in children with chronic non-bacterial osteomyelitis treated with zoledronate

Soucek Ondrej , Cebecauerova Dita , Malcova Hana , Sumnik Zdenek

Introduction: Chronic non-bacterial osteomyelitis (CNO) is a sterile inflammatory disease of the skeleton characterized by local pain and swelling. If first line treatment (non-steroidal anti-inflammatory drugs) fails, bisphosphonates are recommended. There are no randomized controlled studies so far that would clarify the zoledronate efficiency, and also no study systematically exploring the effect on bone mineral density (BMD)....

Does Karyotyping and in situ Hybridization from Three Different Germ Layers Elucidate Low Bone Mineral Density in Turner Syndrome?

Soucek Ondrej , Lebl Jan , Zapletalova Jirina , Vrbicka Dita , Adamova Katerina , Prochazka Martin , Klaskova Eva

Background: Turner syndrome (TS) is caused by a total or partial loss of one X chromosome. Typical features include short stature and primary amenorrhoea. In addition, decreasing trabecular bone mineral density (BMD) and increasing cortical BMD during puberty has been reported at the radius. As chromosomal aberration remains a probable cause of bone changes in TS, we aimed to elucidate whether the karyotype differs among the tissues originating from the three ...

Girls with Turner Syndrome have Normal Muscle Force but Decreased Muscle Power

Soucek Ondrej , Lebl Jan , Matyskova Jana , Snajderova Marta , Kolouskova Stanislava , Pruhova Stepanka , Hlavka Zdenek , Sumnik Zdenek

Background: Turner syndrome (TS) associates with decreased bone mineral density and altered bone geometry, a risk factors leading to increased fracture rate. Although hypogonadism or SHOX gene haploinsufficiency are the probable causes, the exact mechanism remains unclarified. Particularly, the muscle function as an important determinant of bone strength has yet not been widely studied in TS patients.Objective and hypotheses: We hypothesised there is mus...

A homozygous variant in ZSWIM6 causes short stature, microcephaly and developmental delay

Anne Amaratunga Shenali , Bezdicka Martin , Hussein Tayeb Tara , Soucek Ondrej , Lebl Jan

Introduction: The ZSWIM6 gene was first described with a unique de-novo heterozygous variant causing acromelic frontonasal dysostosis, characterized by craniofacial, brain, and limb malformations. Another de-novo heterozygous variant was later described causing severe intellectual disability, hypotonia amd seizures but without craniofacial or limb malformations. These findings suggest a clear genotype-phenotype correlation for ZSWIM6. Gene in...

Comparison of Manual and Automated Bone Age Assessment in 1285 Children and Adolescents Aged 5 to 16 Years

Maratova Klara , Zemkova Daniela , Lebl Jan , Soucek Ondrej , Pruhova Stepanka , Kolouskova Stanislava , Snajderova Marta , Krasnicanova Hana , Sumnik Zdenek

Background: Skeletal maturation is the most reliable indicator of biological age in children and adolescents. The evaluation of hand and wrist X-Ray according to Tanner-Whitehouse (TW3) or Greulich-Pyle (GP) are the most commonly used methods for biological age assessment. Automated bone age assessment has recently become increasingly popular, however a large independent study comparing automated and manual evaluation of bone age is still missing. The aim of this study was to ...
