Despite extensive clinical experience in treating cubital tunnel syndrome, optimal surgical management remains controversial. A meta-analysis of 30 studies with accurate preoperative and postoperative staging was undertaken. Patients were staged preoperatively into minimum, moderate, and severe groups on the basis of clinical presentation. Treatment modalities included nonoperative management, surgical decompression, medial epicondylectomy, anterior subcutaneous transposition, and anterior submuscular transposition. Statistical analysis using a standard SAS database with analysis of variance and chi-square tests was used to assess the efficacy of each therapeutic modality. For minimum-staged patients, all modalities produced similar degrees of satisfaction. However, total relief occurred most after medial epicondylectomy and least after anterior subcutaneous transposition. Patients treated nonoperatively had the highest rate of recurrence. For moderate-staged patients, submuscular transposition was most efficacious, whereas patients with nonoperative management fared the worst. Finally, for severe-staged patients, current therapeutic modalities were not consistently effective, with medial epicondylectomy producing the poorest operative result. This article reveals statistically significant differences in outcomes among therapeutic modalities, which may assist in treatment planning; it introduces standardized methods to aid in determining, analyzing, and communicating treatment outcomes.

Nuclear factor kappaB (NF-kappaB) is thought to play an important role in the expression of genes expressed in response to ischemia/reperfusion (I/R) injury. In this report, the activation of NF-kappaB in rat skeletal muscle during reperfusion following a 4-h ischemic period was studied. NF-kappaB activation displayed a biphasic pattern, showing peak activities from 30 min to 3 h postperfusion and 6 h to 16 h postperfusion, with a decline to baseline binding activity levels between 3 h and 6 h. Inhibition of NF-kappaB activation was investigated using proline dithiocarbamate (Pro-DTC). NF-kappaB binding activity during reperfusion was significantly reduced by intravenous administration of Pro-DTC. Additionally, Pro-DTC resulted in decreased muscle edema and neutrophil activity, with an increased percentage of muscle survival compared with vehicle controls. These results demonstrate that NF-kappaB is activated during reperfusion in a biphasic manner and that the regulation of the initial phase of NF-kappaB activation affords physiological protection against a severe ischemic stress. Selective inhibition of NF-kappaB during early reperfusion may therefore be a therapeutic intervention for I/R injury.

These observations clarify several nuances regarding septal structural stability, septal deformities, and the effects of septal alteration during rhinoplasty. The findings of this study reinforce several principles, including recognition of factors contributing to the high propensity of acquired central septal perforations; preservation of a generous L-strut width, especially at the anterior septal angle, or if planning dorsal hump reduction, prudent allocation of harvested septal cartilage; and clarifying the proclivity for supratip deformity following rhinoplasty.
