The intercostal to phrenic nerve transfer: an effective means of reanimating the diaphragm in patients with high cervical spine injury.
Nerve transfers have been well described for the treatment of congenital and traumatic injuries in the brachial plexus and extremities. This series is the first to describe nerve transfers to reanimate the diaphragm in patients confined to long-term positive pressure ventilation because of high cervical spine injury. Patients who have sustained injury to the spinal cord at the C3 to C5 level suffer axonal loss in the phrenic nerve. ⋯ The average interval from surgery to diaphragm response to electrical stimulation was 9 months. All patients were able to tolerate diaphragmatic pacing as an alternative to positive pressure ventilation, as judged by end tidal CO2 values, tidal volumes, and patient comfort. Intercostal to phrenic nerve transfer with diaphragmatic pacing is a viable means of liberating patients with high cervical spine injury from long-term mechanical ventilation.

All women with advanced breast cancer who are medically stable despite their disease are candidates for tumor extirpation and reconstruction. Advanced breast cancer today is incurable, and many prognostic factors can be used to try to predict a clinical course and response to therapy; however, no guidelines are available. Our case report most likely represents a metastasis to the calvarium with intracranial extension, reported to occur in about 3 percent of primary breast cancer patients. ⋯ Metals, calcium ceramics, and polymers such as methylmethacrylate can be used to cover intracranial contents and restore calvarial contour when defects are large or when autogenous material is not available. Palliation from tumor burden, prevention of pathologic fracture and oncologic emergencies, controlling pain, and enhancing quality of life are the goals of the oncologic and reconstructive surgeons in cases of advanced breast cancer. These goals are becoming even more important as new forms and combinations of chemotherapy, radiation, and gene therapy are extending the life expectancy of women with breast carcinoma.

Pfannenstiel incision as an alternative approach for harvesting the rectus abdominis muscle for free-tissue transfer.
The rectus abdominis muscle has been one of the most commonly used donor tissues for free-flap reconstruction of defects in the extremities and in selected head and neck patients. The rectus abdominis has provided adequate soft-tissue mass with predictable anatomy and results for the majority of its applications in free-flap reconstruction. Harvesting of this muscle has typically been done through a paramedian or midline incision, which has left a lengthy notable scar on a patient's abdomen. ⋯ Cosmesis was judged as good in all patients. We would recommend avoiding this approach in heavy or moderate smokers, diabetic patients, and patients with significant obesity. The Pfannenstiel approach to the rectus abdominis muscle has allowed for complete harvest of the muscle, improved aesthetic results compared with alternative techniques, and avoidance of donor-site morbidityin healthy patients.
