Lim B, Shalan M. Outcome of Bilateral Hand Reconstruction in a Child Presenting Late With Apert Syndrome: A Case Report and Literature Review. Cureus 2023; 15:e43641.

Abstract
Apert syndrome is a rare inherited syndrome characterised by craniosynostosis, midface hypoplasia, and syndactyly of the hands and feet. Syndactyly of the hands is categorised into three types with varying severity, requiring a diverse range of surgical techniques to produce good functional and aesthetic outcomes. The best age to initiate hand reconstruction is between three and 12 months. We present a case of a three-year-old boy with type III syndactyly who first presented at a volunteer outreach surgical campus in Pemba, Zanzibar. A three-stage bilateral hand reconstruction was initiated to sequentially create the first, fourth, and second web spaces. Postoperative healing was uneventful. He underwent a hand rehabilitation program and demonstrated good functional outcomes, being able to attend school, hold a pen, and write by seven years old. A literature review revealed that the best age to initiate hand reconstruction or the best surgical technique to use has yet to be agreed upon. It is agreed that the diverse symptoms of Apert syndrome make it difficult to manage, requiring multidisciplinary collaboration to provide physical and emotional benefits to patients and families.

Alam MK, Alfawzan AA, Srivastava KC, Shrivastava D, Ganji KK, Manay SM. Craniofacial morphology in Apert syndrome: a systematic review and meta-analysis. Sci Rep 2022; 12:5708. [PMID: 35383244 PMCID: PMC8983770 DOI: 10.1038/s41598-022-09764-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Accepted: 03/14/2022] [Indexed: 11/25/2022] Open
Abstract
This meta-analysis aims to compare Apert syndrome (AS) patients with non-AS populations (not clinically or genetically diagnosed) on craniofacial cephalometric characteristics (CCC) to combine publicly available scientific information while also improving the validity of primary study findings. A comprehensive search was performed in the following databases: PubMed, Google Scholar, Scopus, Medline, and Web of Science, an article published between 1st January 2000 to October 17th, 2021. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to carry out this systematic review. We used the PECO system to classify people with AS based on whether or not they had distinctive CCC compared to the non-AS population. Following are some examples of how PECO has been used: People with AS are labeled P; clinical or genetic diagnosis of AS is labeled E; individuals without AS are labeled C; CCC of AS are labeled O. Using the Newcastle–Ottawa Quality-Assessment-Scale, independent reviewers assessed the articles' methodological quality and extracted data. 13 studies were included in the systematic review. 8 out of 13 studies were score 7–8 in NOS scale, which indicated that most of the studies were medium to high qualities. Six case–control studies were analyzed for meta-analysis. Due to the wide range of variability in CCC, we were only able to include data from at least three previous studies. There was a statistically significant difference in N-S-PP (I2: 76.56%; P = 0.014; CI 1.27 to − 0.28) and Greater wing angle (I2: 79.07%; P = 0.008; CI 3.07–1.17) between AS and control subjects. Cleft palate, anterior open bite, crowding in the upper jaw, and hypodontia occurred more frequently among AS patients. Significant shortening of the mandibular width, height and length is the most reported feature in AS patients. CT scans can help patients with AS decide whether to pursue orthodontic treatment alone or to have their mouth surgically expanded. The role of well-informed orthodontic and maxillofacial practitioners is critical in preventing and rehabilitating oral health issues.

Intermetatarsal Coalition: Case Report, Literature Review, and Imaging Findings of an Underrecognized and Underdiagnosed Cause of Foot Pain. Case Rep Radiol 2021; 2021:6667907. [PMID: 33628564 PMCID: PMC7886590 DOI: 10.1155/2021/6667907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 01/22/2021] [Accepted: 01/27/2021] [Indexed: 11/17/2022] Open
Abstract
Coalition is defined as abnormal bridging between two bones, and the connection can be osseous or nonosseous. Most coalitions in the foot involve the hindfoot. Intermetatarsal coalition is thought to be much rarer than the more common hindfoot coalitions and has only been reported sporadically in the orthopedic literature. We present two patients with nonosseous intermetatarsal coalition presenting with nonspecific dorsolateral foot pain and describe the imaging findings of intermetatarsal coalition with different modalities. We suspect that whilst rarely described, intermetatarsal coalition is quite likely a more common underrecognized entity than a rare entity. This report is aimed at increasing the awareness of coalition in this location, in the radiology community, particularly the nonosseous ones, given that this condition can be debilitating but treatable.

Abstract
Autism spectrum disorders are neurodevelopmental conditions with diverse aetiologies, all characterized by common core symptoms such as impaired social skills and communication, as well as repetitive behaviour. Cell adhesion molecules, receptor tyrosine kinases and associated downstream signalling have been strongly implicated in both neurodevelopment and autism spectrum disorders. We found that downregulation of the cell adhesion molecule NEGR1 or the receptor tyrosine kinase fibroblast growth factor receptor 2 (FGFR2) similarly affects neuronal migration and spine density during mouse cortical development in vivo and results in impaired core behaviours related to autism spectrum disorders. Mechanistically, NEGR1 physically interacts with FGFR2 and modulates FGFR2-dependent extracellular signal-regulated kinase (ERK) and protein kinase B (AKT) signalling by decreasing FGFR2 degradation from the plasma membrane. Accordingly, FGFR2 overexpression rescues all defects due to Negr1 knockdown in vivo. Negr1 knockout mice present phenotypes similar to Negr1-downregulated animals. These data indicate that NEGR1 and FGFR2 cooperatively regulate cortical development and suggest a role for defective NEGR1-FGFR2 complex and convergent downstream ERK and AKT signalling in autism spectrum disorders.

Abstract
Gain-of-function mutations in fibroblast growth factor receptors (FGFRs) cause congenital skeletal anomalies, including craniosynostosis (CS), which is characterized by the premature closure of craniofacial sutures. Apert syndrome (AS) is one of the severest forms of CS, and the only treatment is surgical expansion of prematurely fused sutures in infants. Previously, we demonstrated that the prolyl isomerase peptidyl-prolyl cis-trans isomerase interacting 1 (PIN1) plays a critical role in mediating FGFR signaling and that Pin1+/- mice exhibit delayed closure of cranial sutures. In this study, using both genetic and pharmacological approaches, we tested whether PIN1 modulation could be used as a therapeutic regimen against AS. In the genetic approach, we crossbred Fgfr2S252W/+, a mouse model of AS, and Pin1+/- mice. Downregulation of Pin1 gene dosage attenuated premature cranial suture closure and other phenotypes of AS in Fgfr2S252W/+ mutant mice. In the pharmacological approach, we intraperitoneally administered juglone, a PIN1 enzyme inhibitor, to pregnant Fgfr2S252W/+ mutant mice and found that this treatment successfully interrupted fetal development of AS phenotypes. Primary cultured osteoblasts from Fgfr2S252W/+ mutant mice expressed high levels of FGFR2 downstream target genes, but this phenotype was attenuated by PIN1 inhibition. Post-translational stabilization and activation of Runt-related transcription factor 2 (RUNX2) in Fgfr2S252W/+ osteoblasts were also attenuated by PIN1 inhibition. Based on these observations, we conclude that PIN1 enzyme activity is important for FGFR2-induced RUNX2 activation and craniofacial suture morphogenesis. Moreover, these findings highlight that juglone or other PIN1 inhibitors represent viable alternatives to surgical intervention for treatment of CS and other hyperostotic diseases.
