The taxanes, docetaxel and paclitaxel, are microtubule stabilizing chemotherapeutic agents that have demonstrated antineoplastic effects in a variety of solid tumors. They have been linked to the development of localized cutaneous sclerosis in some patients. We present a case of docetaxel-induced cutaneous sclerosis of the lower extremities in a patient with pre-existing CREST syndrome. We propose that patients with a history of limited or diffuse systemic sclerosis should be given taxane chemotherapy with caution, as these patients may have an immunological predisposition for the development of drug-induced morphea.

This case report and video demonstrate the technique of full-endoscopic J-shaped transforaminal L5 exiting nerve decompression in Bertolotti syndrome. Bertolotti syndrome, characterized by a congenital lumbosacral transitional vertebra, often results in mechanical lower back pain and nerve root compression. A 69-year-old male presented with progressive radiating pain in the right leg and tingling in the L5 dermatome.

Lateral Meningocele Syndrome (LMS), a disorder associated with NOTCH3 pathogenic variants, presents with neurological, craniofacial and skeletal abnormalities. Mouse models of the disease exhibit osteopenia that is ameliorated by the administration of Notch3 antisense oligonucleotides (ASO) targeting either Notch3 or the Notch3 mutation. To determine the consequences of LMS pathogenic variants in human cells and whether they can be targeted by ASOs, induced pluripotent NCRM1 and NCRM5 stem (iPS) cells harboring a NOTCH36692-93insC insertion were created.

Background: Smooth muscle cells (SMCs) of cardiac and neural crest origin contribute to the developing proximal aorta and are linked to disease propensity in adults.
Methods: We analyzed single-cell transcriptomes of aortic SMCs from adult mice to determine basal states and changes after disrupting TGFβ (transforming growth factor-β) signaling necessary for aortic homeostasis.
Results: A minority of Myh11 lineage-marked SMCs differentially expressed genes suggestive of embryological origin.
The characteristic of thoracolumbar junction syndrome (TLJS( described by Maigne are pain in the iliac crest and tenderness on palpation at the level of the junction between the lower dorsal and the upper lumbar vertebra. It is an often unrecognized and treatable cause of low back pain. TLJS is commonly associated with those who have low back pain, although it does not always present pain in this region.

Purpose: In PAX6 syndrome, it is still not clear, whether prenatally, parallel to the iris tissue developmental anomaly, there is neural ectodermal, neural crest, or mesodermal cell deposition at the corneal endothelium, affecting endothelial structure and function. In addition, because of the postnatal corneal inflammation and commonly appearing secondary glaucoma, progressive endothelial changes are expected. Our purpose was to study the corneal endothelium in subjects with PAX6 aniridia, using in vivo confocal laser scanning microscopy.
