Comparative StudyThe removal of cutaneous pigmented lesions with the Q-switched ruby laser and the Q-switched neodymium: yttrium-aluminum-garnet laser. A comparative study.
The Q-switched ruby laser (QSRL) (694 nm) has been used successfully in the removal of tattoos and a variety of cutaneous pigmented lesions. The frequency-doubled Q-switched neodymium:yttrium-aluminum-garnet laser (QSNd:YAG) (1064 and 532 nm) has also been shown to be effective in the treatment of tattoos, however, little has been published regarding the QSNd:YAG laser in the removal of cutaneous pigmented lesions. ⋯ Both the QSRL and the frequency-doubled QSND:YAG laser are safe and effective methods of treatment of epidermal and dermal pigmented lesions.

Randomized Controlled Trial Clinical TrialBenzyl alcohol attenuates the pain of lidocaine injections and prolongs anesthesia.
Benzyl alcohol is reported to be painless on injection and to provide limited dermal anesthesia. Benzyl alcohol has also been recommended as an adjuvant to lidocaine to reduce lidocaine's injection pain. There is insufficient data on pain of injection and duration of anesthesia for lidocaine containing benzyl alcohol. ⋯ Benzyl alcohol is itself an effective anesthetic and can reduce the pain of injection for lidocaine without adversely affecting its anesthetic properties.

Comparative Study Clinical Trial Controlled Clinical TrialComparison of iontophoresis of lidocaine with a eutectic mixture of lidocaine and prilocaine (EMLA) for topically administered local anesthesia.
Almost all dermatologic surgery is accomplished using local anesthesia. To make our patients more comfortable, there is a constant search for less painful methods of administering anesthetic agents. Topical EMLA as well as iontophoresis are both useful in this regard. ⋯ Both iontophoresis of lidocaine and topical EMLA delivered significant, and sometimes complete, local anesthesia. A greater degree of anesthesia is delivered via iontophoresis after 30 minutes as compared with EMLA left on the skin for 30 or 60 minutes. Both modalities have important and unique advantages and disadvantages. Topical EMLA and iontophoretically delivered lidocaine are both valuable tools for the dermatologic surgeon.

Extensive scalp lifting, though offering the potential for tremendous benefit to the patient with extensive male-pattern alopecia, has not been widely accepted or understood. ⋯ Present and future advantages of scalp lifting over traditional scalp reduction have been enumerated and discussed.

Randomized Controlled Trial Clinical TrialPain of injection and duration of anesthesia for intradermal infiltration of lidocaine, bupivacaine, and etidocaine.
Bupivacaine and etidocaine are local anesthetics said to be long acting based on nerve block data. There are insufficient data on pain of infiltration and duration of anesthesia when either is used for dermal infiltration to assess suitability for skin surgery. ⋯ Where epinephrine is contraindicated and long anesthesia matters, use plain bupivacaine. When epinephrine can be used, lidocaine lasts almost as long as bupivacaine and hurts less.
