Setting: Tertiary care children's hospital.
Unlabelled: Chronic recurrent multifocal osteomyelitis is a rare autoinflammatory bone disorder of children and adolescents characterized by monofocal or multifocal inflammatory bone lesions that are culture-negative on biopsy, associated with periods of exacerbation and resolution that can last over several months to years. Although it is predominantly a disease of long bones and the spine, craniofacial involvement is not uncommon, affecting the mandible in up to one-fifth of cases. Similarities with other causes of osteitis in clinical presentation and imaging, and the lack of specific symptoms or laboratory tests, make chronic recurrent multifocal osteomyelitis mainly a diagnosis of exclusion.

Soft tissue replacement and repair is crucial to the ever-developing field of reconstructive surgery as trauma, pathology, and congenital deficits cannot be adequately restored if soft tissue regeneration is deficient. Predominant approaches were sometimes limited to harvesting autografts, but through regenerative medicine and tissue engineering, the hope of fabricating custom constructs is now a feasible and fast-approaching reality. The breadth of this field includes tissues ranging from skin, mucosa, muscle, and fat and hopes to not only provide construct to replace a tissue but also to replace its function.

Mutations in the gene coding for laforin are responsible for the development of Lafora disease, a progressive fatal myoclonus epilepsy with early onset, characterized by the intracellular deposition of abnormally branched, hyperphosphorylated insoluble glycogen-like polymers, called Lafora bodies. Despite the known importance of the CBM domain of laforin in the regulation of glycogen metabolism, the molecular mechanism of laforin-glycogen interaction is still poorly understood.

The parent dipyrromethene is desymmetrised through O chelation of boron by the 3,5-ortho-phenolic substituents, inducing a helical chirality in the fluorophore. The combination of high luminescence dissymmetry factors (|glum | up to 4.

This study compared the efficacy of computed tomography (CT) and magnetic resonance imaging (MRI) in the evaluation of JOF and thus could aid establishing such guidelines.
Materials And Methods: Radiologic criteria were established by 2 radiologists to compare the efficacy of CT and MRI in the evaluation of JOF.
Each year, millions of Americans suffer bone fractures, often requiring internal fixation. Current devices, like plates and screws, are made with permanent metals or resorbable polymers. Permanent metals provide strength and biocompatibility, but cause long-term complications and may require removal.

Purpose: Internal bone fixation devices made with permanent metals are associated with numerous long-term complications and may require removal. We hypothesized that fixation devices made with degradable magnesium alloys could provide an ideal combination of strength and degradation, facilitating fracture fixation and healing while eliminating the need for implant removal surgery.
Materials And Methods: Fixation plates and screws were machined from 99.

Purpose: The presence of a functional periosteum accelerates healing in bone defects by providing a source of progenitor cells that aid in repair. We hypothesized that bone marrow stromal cell (BMSC) sheets could be used to engineer functional periosteal tissues.
Materials And Methods: BMSCs were cultured to hyperconfluence and produced sufficient extracellular matrix to form robust tissue sheets.

The purpose of craniomaxillofacial surgery is to improve function, occlusion, craniofacial balance, and aesthetics. Accurate diagnosis, assessment, and careful treatment planning are essential in achieving a successful outcome, and an understanding of the pattern of facial growth is integral in this process. Patients with craniofacial congenital dysmorphologies, posttraumatic asymmetries, or disturbances of facial balance from radiation may have functional and/or aesthetic issues that require treatment.

They may also prove useful in developing new therapeutic approaches to head and neck cancer. The surgeon working in the craniomaxillofacial region should have an understanding of these technologies, their availability in various settings, and how they affect various aspects of treatment, particularly in the detection and treatment of malignancies.
