Forequarter Amputation and Resection of Ribs 1-4 for Chronic Osteomyelitis.

A 78-year-old woman with a history of breast cancer, melanoma, and radiation therapy presented with worsening chronic osteomyelitis and radiation necrosis of her clavicle, scapula, and upper ribs. Despite treatment with vancomycin, she experienced significant lymphedema and near-total loss of motor function in the left upper extremity. Given the progression of the disease and diminished functionality of the limb, a forequarter amputation was determined to be the only viable option beyond supportive care.

Quantifying Mitochondrial Dynamics in Patient Fibroblasts with Multiple Developmental Defects and Mitochondrial Disorders.

Mitochondria are dynamic organelles that undergo rounds of fission and fusion and exhibit a wide range of morphologies that contribute to the regulation of different signaling pathways and various cellular functions. It is important to understand the differences between mitochondrial structure in health and disease so that therapies can be developed to maintain the homeostatic balance of mitochondrial dynamics. Mitochondrial disorders are multisystemic and characterized by complex and variable clinical pathologies.
