RESUMO
OBJECTIVE: To determine indications for the use of postmastectomy radiotherapy (PMRT) for patients with invasive breast cancer with involved axillary lymph nodes or locally advanced disease who receive systemic therapy. These guidelines are intended for use in the care of patients outside of clinical trials. POTENTIAL INTERVENTION: The benefits and risks of PMRT in such patients, as well as subgroups of these patients, were considered. The details of the PMRT technique were also evaluated. OUTCOMES: The outcomes considered included freedom from local-regional recurrence, survival (disease-free and overall), and long-term toxicity. EVIDENCE: An expert multidisciplinary panel reviewed pertinent information from the published literature through July 2000; certain investigators were contacted for more recent and, in some cases, unpublished information. A computerized search was performed of MEDLINE data; directed searches based on the bibliographies of primary articles were also performed. VALUES: Levels of evidence and guideline grades were assigned by the Panel using standard criteria. A "recommendation" was made when level I or II evidence was available and there was consensus as to its meaning. A "suggestion" was made based on level III, IV, or V evidence and there was consensus as to its meaning. Areas of clinical importance were pointed out where guidelines could not be formulated due to insufficient evidence or lack of consensus. RECOMMENDATIONS: The recommendations, suggestions, and expert opinions of the Panel are described in this article. VALIDATION: Seven outside reviewers, the American Society of Clinical Oncology (ASCO) Health Services Research Committee members, and the ASCO Board of Directors reviewed this document.

OBJECTIVE: To determine whether low-intensity laser irradiation, a widespread but controversial physical therapy agent, is an effective treatment of plantar fasciitis. DESIGN: A randomized, double-blinded, placebo-controlled clinical study. SETTING: A sports medicine clinic. SUBJECTS: Thirty-two otherwise healthy individuals with plantar fasciitis of more than 1 month's duration. INTERVENTION: Dummy or active irradiation with a 30 mW .83 microm GaAlAs continuous-wave infrared (IR) diode laser three times a week for 4 weeks. MEASUREMENTS: Morning pain, pain with toe walking, tenderness to palpation, windlass test response, medication consumption, and orthotic use were evaluated immediately before the study, as well as at the midpoint and end of treatment. Subjects were also evaluated at a follow-up 1 month after their last treatment. RESULTS: No significant differences were found between the groups in any of the outcome measures either during treatment or at the 1-month follow-up. Treatment, however, was well tolerated and side effects were minimal. CONCLUSIONS: Low-intensity IR laser therapy appears safe but, at least within the parameters of this study, is not beneficial in the treatment of plantar fasciitis.

India ink skin markings allow consistently reproducible radiation field setups. The authors report a case in which a facial tattoo was applied with an injection, resulting in permanent "black eyes." The vaccination technique has not been associated with this complication.

A range of sonographic patterns in patients with hydatidiform moles can be appreciated with gray scale ultrasonography, which more readily reveals areas of internal hemorrhagic degeneration and fetal growth within a molar mass. Sonography may be used to evaluate patients suspected of having recurrent or invasive trophoblastic disease; a focus of invasive trophoblastic tumor can be identified as a cluster of high-amplitude echoes within the myometrium, which is frequently associated with echo-free areas of hemorrhage. The enlargement or regression of theca lutein cysts associated with these disease processes can also be monitored.
