Comparative Study
Quantification of pain and satisfaction following laparoscopic and open hernia repair.
Subjective experiences can be quantified by visual analog scale (VAS) scoring to improve comparison of surgical techniques. ⋯ Pain following hernia repair was age dependent. Following laparoscopic repair, patients had lower first-day pain scores in younger patients and earlier return to normal activities in all patients. Satisfaction was similar for both approaches. Subjective experiences can be quantified, compared to detect subtle differences in outcome for competing surgical techniques, and used to counsel patients before operation, with the goal of improving satisfaction.

Partial-breast irradiation for carcinoma by a single source of radiation placed in the center of a balloon inserted in the lumpectomy cavity is an effective method of treating breast cancer. Previous interstitial radiation therapy using iridium seeds placed within multiple catheters has been shown to be effective but impractical and cosmetically unacceptable to women. ⋯ Our early short-term experience indicates balloon brachytherapy to be an acceptable alternative to external beam radiation for selected operable breast cancers. The 1-week treatment time allows working women and those who live at a distance from radiation centers to choose breast conservation rather than mastectomy.

The presence of nonsentinel lymph node (NSLN) metastasis after having a positive sentinel lymph node dissection finding is associated with tumor size and stage, the presence of lymphovascular invasion, micrometastasis, and extranodal extension. ⋯ Although primary tumor size and micrometastases correlate with the status of the NSLNs, extranodal extension is the most important independent predictor of NSLN metastasis. These findings may ultimately spare patients a full axillary lymph node dissection. However, pending results of larger clinical trials, full axillary lymph node dissection is still recommended for patients with sentinel lymph node metastases.

The acute phase response is a cascade of events contributing to hypermetabolism and substrate catabolism. It was believed to persist for only a short time after injury. There is now evidence that systemic catabolism and hypermetabolism associated with thermal injury persevere for a long time. We hypothesize that the proinflammatory hepatic acute phase response perseveres for an extended time and enhances hypermetabolism longer than previously believed. ⋯ Despite adequate nutritional support, a severe thermal injury induces the proinflammatory acute phase response for a prolonged period. Thus, the liver with the hepatic acute phase response plays a more important role during catabolism after burn than previously believed. Pharmacologic agents that improve hepatic function may be an effective approach to attenuate hypermetabolism after trauma.

Multiple organ dysfunction (MOD) within 48 hours of injury is a reversible physiologic response to tissue injury and resuscitation. ⋯ Multiple organ dysfunction during resuscitation is a reversible response to severe injury and often resolves during the resuscitation period.
