Epsilon Aminocaproic Acid's Safety and Efficacy in Pediatric Surgeries Including Craniosynostosis Repair: A Review of the Literature.

Cureus 2022 May 21;14(5):e25185. Epub 2022 May 21.

Pediatric Surgery, University of Central Florida College of Medicine, Orlando, USA.

Craniosynostosis, the premature fusion of skull sutures in children, requires surgical correction. This procedure routinely requires allogeneic blood transfusions, which are associated with multiple risks of their own. Since 2008, antifibrinolytics tranexamic acid (TXA) and epsilon aminocaproic acid (EACA or Amicar) have been widely used. Read More

Molecular genetics of human developmental neurocranial anomalies: towards "precision surgery".

Cereb Cortex 2022 Jun 24. Epub 2022 Jun 24.

Department of Neurosurgery, Massachusetts General Hospital and Harvard Medical School, Boston, MA, USA.

Recent trio-based whole-exome sequencing studies of congenital hydrocephalus and nonsyndromic craniosynostosis have identified multiple novel disease genes that have illuminated the pathogenesis of these disorders and shed new insight into the genetic regulation of human brain and skull development. Continued study of these and other historically understudied developmental anomalies has the potential to replace the current antiquated, anatomically based disease classification systems with a molecular nomenclature that may increase precision for genetic counseling, prognostication, and surgical treatment stratification-including when not to operate. Data will also inform future clinical trials, catalyze the development of targeted therapies, and generate infrastructure and publicly available data sets relevant for other related nonsurgical neurodevelopmental and neuropsychiatric diseases.

somatic mosaicism in a patient with bilateral optic nerve sheath meningiomas: illustrative case.

J Neurosurg Case Lessons 2022 Jun 6;3(23):CASE2247. Epub 2022 Jun 6.

Departments of Ophthalmology.

Background: In the past decade, next-generation sequencing has spurred significant progress in the understanding of cytogenetic alterations that occur in meningiomas. Eighty percent of adult meningiomas harbor pathogenic somatic variants involving , , , , , or Somatic variants in associated with meningiomas usually localize to the gene's WD40 domains but are mutually exclusive to germline mutations, which cause a distinctive autosomal dominant syndrome.

Observations: This case involved a 15-year-old girl with bilateral optic nerve sheath meningiomas, diffuse meningiomatosis, and syndromic features, including craniosynostosis, brain anomalies, syndactyly, brachydactyly, epicanthus, and patent ductus arteriosus. Read More

Cranial Morphology Associated With Syndromic Craniosynostosis: A Potential Detection of Abnormality in Patient's Cranial Growth Using Angular Statistics.

Cleft Palate Craniofac J 2022 Jun 16:10556656221107524. Epub 2022 Jun 16.

Centre for Defence Foundation Studies, 132053National Defence University of Malaysia, Kuala Lumpur, Malaysia.

Introduction: Apert, Crouzon, and Pfeiffer syndromes are common genetic syndromes related to syndromic craniosynostosis (SC), whereby it is a congenital defect that occurs when the cranial growth is distorted. Identifying cranial angles associated with these 3 syndromes may assist the surgical team to focus on a specific cranial part during the intervention planning, thus optimizing surgical outcomes and reducing potential morbidity.

Objective: The aim of this study is to identify the cranial angles, which are associated with Apert, Crouzon, and Pfeiffer syndromes. Read More

structural variants disrupting transcriptional regulation lead to craniofacial and limb malformations.

Genome Res 2022 Jun 16. Epub 2022 Jun 16.

Ben-Gurion University of the Negev;

Structural variants (SVs) can affect protein-coding sequences as well as gene regulatory elements. However, SVs disrupting protein-coding sequences that also function as cis-regulatory elements remain largely uncharacterized. Here, we show that craniosynostosis patients with SVs containing the Histone deacetylase 9 (HDAC9) protein-coding sequence are associated with disruption of regulatory elements that reside within sequence.

Mechanical loading of cranial joints minimizes the craniofacial phenotype in Crouzon syndrome.

Sci Rep 2022 Jun 11;12(1):9693. Epub 2022 Jun 11.

Developmental Biology and Cancer Research and Teaching Department, UCL Great Ormond Street Institute of Child Health, University College London, London, UK.

Children with syndromic forms of craniosynostosis undergo a plethora of surgical interventions to resolve the clinical features caused by the premature fusion of cranial sutures. While surgical correction is reliable, the need for repeated rounds of invasive treatment puts a heavy burden on the child and their family. This study explores a non-surgical alternative using mechanical loading of the cranial joints to prevent or delay craniofacial phenotypes associated with Crouzon syndrome. Read More

Handchir Mikrochir Plast Chir 2022 Jun 10;54(3):187-196. Epub 2022 Jun 10.

Medizinische Universität Innsbruck Universitätsklinik für Plastische und Wiederherstellungsschirurgie.

The necessity for early surgical correction of Apert hands for the overall child development has been highlighted repeatedly in older literature. Nevertheless, uncertainties regarding the time and the scale of the initial surgical treatment still remain. While in former times there were no regular follow-ups after the syndactyly release, we now know that during growth bony changes will develop in the Apert hand requiring regular check-ups and, in some cases, revision surgeries.

Genetic Interaction of and Shapes Postnatal Craniofacial Bone.

J Dev Biol 2022 May 11;10(2). Epub 2022 May 11.

Department of Anatomy and Cell Biology, University of Kansas Medical Center, Kansas City, KS 66160, USA.

Ciliopathies are genetic syndromes that link skeletal dysplasias to the dysfunction of primary cilia. Primary cilia are sensory organelles synthesized by intraflagellar transport (IFT)-A and B complexes, which traffic protein cargo along a microtubular core. We have reported that the deletion of the IFT-A gene, , together with a null allele of its paralog, causes a small skeleton with a small mandible or micrognathia in juvenile mice. Read More

Tranexamic Acid and Its Potential Anti-Inflammatory Effect: A Systematic Review.

Semin Thromb Hemost 2022 May 30. Epub 2022 May 30.

Department of Clinical Medicine, Health, Aarhus University, Aarhus C, Denmark.

Tranexamic acid (TXA) is an antifibrinolytic drug primarily used for reducing blood loss in patients with major bleedings. Animal and cell studies have shown that TXA might modulate the inflammatory response by either enhancing or inhibiting cytokine levels. Furthermore, recent human studies have found altered inflammatory biomarkers in patients receiving TXA when compared with patients who did not receive TXA. Read More

Squamosal Suture Synostosis: An Under-Recognized Phenomenon.

Cleft Palate Craniofac J 2022 May 20:10556656221100675. Epub 2022 May 20.

6595University of Pittsburgh Medical Center, Pittsburgh, PA, USA.

Introduction: The squamosal suture (SQS) joins the temporal to the parietal bones bilaterally and is a poorly described site of craniosynostosis. SQS fusion is thought to occur as late as the fourth decade of life and beyond; however, we have incidentally noted its presence among our pediatric patients and hypothesize that it may occur earlier in life and more frequently than previously believed.

Methods: A retrospective review of imaging performed on pediatric patients was completed to identify patients with SQS synostosis. Read More
