  • RESEARCH PROGRESS OF PATHOGENESIS MECHANISM OF SPINAL DEFORMITY IN NEUROFIBROMATOSIS TYPE 1

    ObjectiveTo review the research progress of pathogenesis mechanism of spinal deformity in neurofibromatosis type 1 (NF1). MethodsRecent literature concerning the pathogenesis mechanism of spinal deformity in NF1 was extensively reviewed, and current developments of the correction of spinal deformity and NF1 and the pathogenesis mechanism were summarized. ResultsThe pathogenesis mechanism of spinal deformity in NF1 is not yet clearly known. Current theories include erosion and stress of neurofibromas, melatonin-related decreased contractility of paraspinal muscles, osteopenia and osteoporosis, sexual precocity and mesoderm dysplasia. ConclusionThe clinical manifestations of NF1 may cause the spinal deformities in patients with NF1. The research of pathogenesis mechanism of spinal deformity in NF1 will be conducive to further understanding, diagnosis and treatment of NF1-related spinal deformity.

  • Treatment and progress of cutaneous neurofibroma

    ObjectiveTo summarize current widely-used therapies for cutaneous neurofibroma (cNF) and related research progress. MethodsBased on extensive investigation of domestic and foreign research, the existing treatment of cNF, including the indications, effectiveness and trials of targeted drugs were reviewed. ResultscNF is a hallmark feature of neurofibromatosis type 1 and has a dramatic negative impact on patient appearance and quality of life. At present, there is no standard management of cNF. Invasive treatment is a commonly-used treatment. Surgical removal gives excellent cosmetic results, but it is difficult for multiple tumors; CO2 laser ablation, laser photocoagulation, electro-drying, and radiofrequency ablation are effective in treating lots of cNF at one time. Although fast and effective, these therapies can lead to depigmentation, hyperpigmentation, or extensive scarring. There is no targeted drug approval for cNF, and a series of studies have been carried out on the Ras-MEK pathway, Ras-mTOR pathway, receptor tyrosine kinase, et al. ConclusionThe treatment of cNF has developed rapidly in recent years and has broad prospects, but the individualization and precision of the treatment still needs further clinical research.

  • Fundus image observation of choroidal nodules in neurofibromatosis type 1

    ObjectiveTo observe the imaging characteristics of fundus choroidal nodules in patients with neurofibromatosis type 1 (NF1). MethodsA retrospective clinical study. From January 2018 to August 2022, 20 eyes of 10 patients with NF1 combined with choroidal nodules who were diagnosed by ophthalmology examination at the Affiliated Hospital of Yunnan University were included in the study. Among them, there were 6 male cases with 12 eyes and 4 female cases with 8 eyes; both eyes were affected. Age was (28.0±6.9) years old. Both eyes were involved. All patients underwent color fundus photography, infrared fundus photography (IR), fundus autofluorescence (FAF), fluorescein fundus angiography (FFA), and optical coherence tomography (OCT). Nine eyes underwent multi-wavelength color imaging (MC) and 5 eyes underwent OCT angiography (OCTA). ResultsIn 20 eyes, fundus color photography showed "spiral-like" changes in the small retinal blood vessels on the surface of the choroidal nodules in 1 eye. FAF and FFA examination showed no abnormalities in all affected eyes. On IR examination, choroidal nodules appeared as strong reflective lesions of varying sizes and numbers, in the form of spots and/or sheets, and were partially fused. In the 9 eyes that underwent MC examination, patchy red signals was observed in standard MC images. OCT examination showed that all affected eyes had strong choroidal reflective mass lesions under the retinal pigment epithelium, which were flat patchy or slightly raised “dome-like”, corresponding to IR strong reflective lesions. The choriocapillaris layer was squeezed and thinned, and the large choroidal vessels show weak reflection. Five eyes underwent OCTA examination, there was no loss of blood flow density at the choroidal nodules and the of the superficial an deep retinal capillary plexus in 3 eyes. The choroidal capillary blood flow density was reduced in 2 eyes. ConclusionIR of choroidal nodules is characterized by strong reflection lesions of varying sizes and numbers, which appear in spots and/or sheets. OCT shows enhanced reflection of the choriocapillaris layer corresponding to the strong IR reflection lesions.
