J Craniofac Surg 2022 May 12;33(3):e342-e345. Epub 2021 Oct 12.

Department of Plastic and Reconstructive Surgery, Seoul National University Bundang Hospital, Seongnam.

Background: Fibrous dysplasia (FD) is a rare sporadic benign disease, which involves from single to several bones with unilateral distribution. Recently, image-based surgical navigation systems have played a significant role in surgical process on neurological and orthopedic operations. However, because an intraoral approach can visualize the field for maxillary surgery, there are few cases using endoscopes for excision of FD. Read More

FAM111A is dispensable for electrolyte homeostasis in mice.

Sci Rep 2022 Jun 17;12(1):10211. Epub 2022 Jun 17.

Department of Physiology, Radboud Institute for Molecular Life Sciences, Radboud University Medical Center, P.O. Box 9101, 6500 HB, Nijmegen, The Netherlands.

Autosomal dominant mutations in FAM111A are causative for Kenny-Caffey syndrome type 2. Patients with Kenny-Caffey syndrome suffer from severe growth retardation, skeletal dysplasia, hypoparathyroidism, hypocalcaemia, hyperphosphataemia and hypomagnesaemia. While recent studies have reported FAM111A to function in antiviral response and DNA replication, its role in regulating electrolyte homeostasis remains unknown. Read More

Lifelong immunosuppression is required for allograft survival after kidney transplantation but may not ultimately prevent allograft loss resulting from chronic rejection. We developed an approach that attempts to abrogate immune rejection and the need for post-transplantation immunosuppression in three patients with Schimke immuno-osseous dysplasia who had both T-cell immunodeficiency and renal failure. Each patient received sequential transplants of αβ T-cell-depleted and CD19 B-cell-depleted haploidentical hematopoietic stem cells and a kidney from the same donor. Read More

Isidro Ferrer

Int J Mol Sci 2022 Jun 6;23(11). Epub 2022 Jun 6.

Network Centre of Biomedical Research of Neurodegenerative Diseases (CIBERNED), Department of Pathology and Experimental Therapeutics, Bellvitge Biomedical Research Institute (IDIBELL), University of Barcelona, 08907 Barcelona, L'Hospitalet de Llobregat, Spain.

Primary microglial leukodystrophy or leukoencephalopathy are disorders in which a genetic defect linked to microglia causes cerebral white matter damage. Pigmented orthochromatic leukodystrophy, adult-onset orthochromatic leukodystrophy associated with pigmented macrophages, hereditary diffuse leukoencephalopathy with (axonal) spheroids, and adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) are different terms apparently used to designate the same disease. However, ALSP linked to dominantly inherited mutations in (colony stimulating factor receptor 1) cause CSF-1R-related leukoencephalopathy (CRP). Read More

Sci Rep 2022 Jun 8;12(1):9488. Epub 2022 Jun 8.

Department of Biochemistry, School of Medicine, Iran University of Medical Sciences, P.O. Box: 1449614535, Tehran, Iran.

This study is aimed to unravel the status of local and circulating β-catenin in different primary bone tumors and its relevance to tumor types, severity, and chemotherapy. The β-catenin mRNA expression level and the expression of the protein (intensity level) were evaluated in tumor tissue and peripheral blood mononuclear cells of 150 patients with different types of primary bone tumors (78 malignant and 72 benign tumors) using Real-Time PCR and immunohistochemistry. The β-catenin mRNA expression level and the expression of the protein were increased in bone tumors which was positively correlated with the tumor malignancy. Read More

Chulalongkorn University , Faculty of Medicine , Department of Pediatrics, Medical Genomics Cluster , Center of Excellence for Medical Genomics, Bangkok , Thailand .

Objectives: Cleidocranial dysplasia (CCD) is a skeletal disorder affecting cranial sutures, teeth, and clavicles, and is associated with the RUNX2 mutations. Although numerous patients have been described, a direct genotype-phenotype correlation for RUNX2 has been difficult to establish. Further cases must be studied to understand the clinical and genetic spectra of CCD. Read More

Risk of developing spontaneous MRONJ in fibrous dysplasia patients treated with bisphosphonates: a systematic review of the literature.

Quintessence Int 2022 Jun;53(7):616-623

Objective: The objective of this systematic review was to evaluate the risks of medication-related osteonecrosis of the jaw (MRONJ) in fibrous dysplasia (FD) and McCune-Albright syndrome (MAS) patients treated with bisphosphonates.

Method And Materials: A systematic review of the literature was performed by searching PubMed and Embase databases using MeSH terms (fibrous dysplasia of bone, "fibrous dysplasia, polyostotic," osteonecrosis, jaw, therapeutics, diphosphonates, denosumab, teriparatide, estrogens, hormones, raloxifene hydrochloride, calcitonin, cathepsin K) and non-MeSH terms (antiresorptive therapy, antiresorptives, bisphosphonate, estrogen therapy, hormone therapy, bazedoxifene, cathepsin K inhibitor). Articles were limited to human studies, in English language, in which patients were on antiresorptives for at least 1 year. Read More

Dynamic insights into the effects of nonsynonymous polymorphisms (nsSNPs) on loss of TREM2 function.

Sci Rep 2022 Jun 7;12(1):9378. Epub 2022 Jun 7.

Department of Anatomy, Dongguk University College of Medicine, Gyeongju, 38066, Republic of Korea.

Single nucleotide variations in Triggering Receptor Expressed on Myeloid Cells 2 (TREM2) are associated with many neurodegenerative diseases, including Nasu-Hakola disease (NHD), frontotemporal dementia (FTD), and late-onset Alzheimer's disease because they disrupt ligand binding to the extracellular domain of TREM2. However, the effects of nonsynonymous single nucleotide polymorphisms (nsSNPs) in TREM2 on disease progression remain unknown. In this study, we identified several high-risk nsSNPs in the TREM2 gene using various deleterious SNP predicting algorithms and analyzed their destabilizing effects on the ligand recognizing region of the TREM2 immunoglobulin (Ig) domain by molecular dynamics (MD) simulation.

Osteogenesis imperfecta (OI) is a group of genetic disorders characterized mainly by fractures and bone deformities. It has been established that gene mutations, particularly those in COL1A1 and COL1A2, account for most phenotypes. Here, we generated an induced pluripotent stem cells (iPSCs) line named SMBCi014-A using urine cells (UCs) derived from a 15-year-old female OI type I patient who carried the frame-shift mutation of the COL1A1 gene (exon35:c.

Rapidly Growing Solitary Osteochondroma in the Adult Finger A Case Report.

Bull Hosp Jt Dis (2013) 2022 Jun;80(2):171-174

Osteochondromas are common benign bone tumors that are most commonly found in children and adolescents. They are usually slow-growing and located at the metaphysis of the long bones. When present in adults in atypical locations or with concerning features, such as thickened cartilage cap and rapid growth, osteochondromas warrant imaging to assess the risk of malignant transformation into chondrosar- coma and may require surgical excision.

Controlled repositioning and primary osteoplasty as a treatment option for the management of unstable slipped capital femoral epiphysis.

J Pediatr Orthop B 2022 Jul 24;31(4):359-364. Epub 2022 May 24.

Department of Orthoapedics and Spine Surgery, Ganga Hospital, Coimbatore, India.

The ideal management of an unstable slipped capital femoral epiphysis (SCFE) is still controversial. The currently available options are in-situ screw fixation with delayed corrective osteotomy, closed reduction and screw fixation and anatomic reduction by modified Dunn's procedure (MDP). We present the results of our technique of controlled re-positioning (CRP) with primary osteoplasty in which the epiphysis is repositioned to the preacute slip stage and a mini-open osteoplasty is done in the same sitting to avoid later femoro-acetabular impingement.
