Palliative re-irradiation for in-field recurrence after definitive radiotherapy in patients with primary lung cancer.

Aim: To evaluate the efficacy and toxicity of palliative re-irradiation for in-field recurrence of primary lung cancer after radiotherapy.

Patients And Methods: Forty-four patients with locally recurrent lung cancer after radiotherapy were retreated with external beam radiation therapy. To evaluate palliative effectiveness, 31 symptoms in 25 patients were analyzed, while all patients were analyzed to evaluate pulmonary toxicity.

Characteristics of muscle fibers reconstituted in the regeneration process of masseter muscle in an mdx mouse model of muscular dystrophy.

Mdx mice, which lack dystrophin, were examined for changes in the properties of muscle fibers in the growth process of the masseter muscle at the morphological, protein and transcriptional levels. The slow-type isoform, MyHC-1, and the fast-type isoforms, MyHC-2a, MyHC-2d and MyHC-2b, were examined at the protein and the transcriptional level. Morphological examination showed that in the mdx mouse masseter muscle, degeneration, necrosis, and regeneration occurred, particularly at the age of 4 weeks, and many regenerated muscle fibers with centrally located nuclei were observed at the age of 9 weeks.

A 26-year-old man presented with complaints of exertional dyspnea and cough. The patient has already been given corticosteroids at a previous hospital. Chest CT revealed small centrilobular nodules with diffuse ground-glass opacities in both lungs.

A 57-year-old man was admitted for pulmonary emphysema. Volume-reduction-surgery (VRS) was performed. Three days later, after he coughed hard, the right lung collapsed.
