The role of tissue expansion in the management of large congenital pigmented nevi of the forehead in the pediatric patient.
The authors present a cohort of 21 consecutive patients who had congenital pigmented nevi covering 15 to 65 percent of the forehead and adjacent scalp and who were treated at their institution within the last 12 years. All patients were treated with an expansion of the adjacent texture- and color-matched skin as the primary modality of treatment. The median age at presentation was approximately 1 year; mean postoperative follow-up was 4 years. ⋯ When the temporoparietal scalp is also involved with nevus, a transposition flap (actually a combined advancement and transposition flap because the base of the pedicle moves forward as well) provides the optimal hair direction for the temporal hairline and allows significantly greater movement of the expanded flap, thereby minimizing the need for serial expansion. (5) Once the brow is significantly elevated on either the ipsilateral or contralateral side from the reconstruction, it can only be returned to the preoperative position with the interposition of additional, non-hair-bearing forehead skin. Expansion of the deficient area alone will not reliably lower the brow once a skin deficiency exists. (6) In general, one should always use the largest expander possible beneath the uninvolved forehead skin, occasionally even carrying the expander under the lesion. Expanders are often overexpanded.

Breast cancer after augmentation mammaplasty: treatment by skin-sparing mastectomy and immediate reconstruction.
Breast conservation has been associated with poor cosmetic outcome when used to treat breast cancer in patients who have undergone prior augmentation mammaplasty. Radiation therapy of the augmented breast can increase breast fibrosis and capsular contraction. Skin-sparing mastectomy and immediate reconstruction are examined as an alternative treatment. ⋯ The aesthetic results were judged to be good to excellent in all cases. Skin-sparing mastectomy and immediate reconstruction can be used in patients with prior breast augmentation, with good to excellent cosmetic results. Depending on the tumor and implant location, the implant may be preserved without compromising local control.

Randomized Controlled Trial Comparative Study Clinical TrialDo not use epinephrine in digital blocks: myth or truth?
The purpose of this study was to examine the role for epinephrine augmentation of digital block anesthesia by safely prolonging its duration of action and providing a temporary hemostatic effect. After obtaining approval from the review board of the authors' institution, 60 digital block procedures were performed in a prospective randomized double-blinded study. The digital blocks were performed using the dorsal approach. ⋯ By prolonging lidocaine's duration of action, epinephrine may prevent the need for an additional injection and prolong post-procedure pain relief. This study demonstrated that the temporary hemostatic effect of epinephrine decreased the need for, and thus the potential risk of, using a digital tourniquet (p < 0.002). As the temporary vasoconstrictor effect is reversible, the threat of complication from vasoconstrictor-induced ischemia is theoretical.

Comparative StudyComparative study of two series of distally based fasciocutaneous flaps for coverage of the lower one-fourth of the leg, the ankle, and the foot.
Skin defects over the lower one-fourth of the leg and over the foot are difficult to cover. Two types of pedicled fasciocutaneous flaps used to cover such defects were studied: the lateral supramalleolar flap and the distally based sural neurocutaneous flap. The series consisted of 27 and 36 cases, respectively. ⋯ Though the lateral supramalleolar artery flap offers the possibility of covering the same areas as the sural neurocutaneous flap, it is much less reliable in the presence of diminished local vascularity (18.5 percent failure rate as compared with 4.8 percent for the sural neurocutaneous flap). Because the procedure can cover extensive defects and is easy to perform, the distally based sural neurocutaneous flap was the method of choice for covering skin defects over the foot, heel, ankle, and the lower one-fourth of the leg. The lateral supramalleolar artery flap is indicated only when the sural neurocutaneous flap is contraindicated.
