"Reverse" dual-plane mammaplasty.

BACKGROUND: The authors present a new type of dual-plane mammaplasty and preliminary results obtained with it. The technique is aimed at improving the final natural appearance of breasts without adding additional risks of dislocation. METHODS: The eligibility criteria specified patients with sufficient breast tissue to disguise the implant, patients with asymmetric hypoplasia, and patients with an intense workout activity. The exclusion criteria specified patients with very little breasts. The technique is based on combined subglandular positioning in the superior part of the breast and retrofascial-precostal positioning in the inferior part. RESULTS: Beginning in January 2000, 57 patients were recruited. No postoperative bleedings, hematomas, or seromas were observed. In 93% of cases, good final shapes were obtained. After 1 year of follow-up evaluation, no displacement, asymmetry, or rupture was recorded. Only three patients (5.3%) showed mild monolateral capsular contractures (Baker II type), which resolved using capsulotomy without prostheses removal. CONCLUSIONS: "Reverse" dual-plane mammaplasty is a new technique that gives a good anatomic final appearance with no risk of displacement. The low risk of complications renders it feasible and safe for aesthetic breast augmentation. Further studies are necessary to compare this technique with retroglandular and retropectoral approaches.

Absence of the cell cycle inhibitor p27Kip1 protein predicts poor outcome in patients with stage I-III colorectal cancer.

BACKGROUND: The p27Kip1 protein regulates the G1 to S phase transition of cell cycle by binding to and inhibiting the cyclin E/Cdk2 complex. This study explores the prognostic significance of the absence of the p27Kip1 protein in patients with colorectal cancer (CRC). METHODS: Formalin-fixed tumor sections from 124 patients who underwent curative resection for stage I-III CRC were analyzed by immunohistochemistry using MoAb anti-p27KiP1. RESULTS: Detectable levels of p27Kip1 protein were found in 86% of tumors. Median follow-up was 55 months. Actuarial 5-year disease-free survival (DFS) and overall survival (OS) were 76% and 85%, respectively, in patients with tumors with p27Kip1 protein expression and 34% and 40%, respectively, in those whose tumors lacked p27Kip1 protein expression (P < .001). At multivariate analysis, tumor stage (III vs. I-II) and p27Kip1 protein status (absence vs. presence) were found to be independent prognostic factors for DFS and OS. CONCLUSIONS: Lack of p27KiP1 protein expression in CRC is a negative prognostic marker and may therefore be useful in selecting early-stage patients more likely to benefit from adjuvant treatment.

Reduction of brown fat 2-deoxy-2-[F-18]fluoro-D-glucose uptake by controlling environmental temperature prior to positron emission tomography scan.

UNLABELLED: Brown fat uptake of 2-deoxy-2-[F-18]fluoro-D: -glucose (FDG) on a positron emission tomography (PET) scan limits the ability to assess for cancer. Drugs such as benzodiazepine, propranolol, and reserpine have been proposed to reduce this uptake, but the studies have been either small clinical or preclinical trials. As an alternative, we evaluated the effect of controlling the patient's environmental temperature on brown fat uptake of FDG. METHOD: From January 1, 2002 to November 30, 2004, patients were identified who had (1) a pattern of FDG uptake in the neck/paravertebral areas suggestive of brown fat, (2) a repeat FDG-PET scan after control of the patient's environmental temperature, and (3) no evidence of cancer in the neck/paravertebral areas by other diagnostic methods. For the follow-up PET scan, all patients wore warm clothing and avoided exposure to cold air during their transit to our facility. After arrival, patients were kept in a separate temperature-controlled room (at least 75 degrees F) for 15 minutes to two hours before FDG injection as well as during the uptake phase. Four physicians blindly and retrospectively assessed the FDG uptake in the neck and paravertebral regions on all initial and temperature-controlled PET scans by visually grading the radioactivity on a semiquantitative scale (0 = background, 1+ = background but liver). The changes in maximal SUVs were determined in the left and right neck region. Data were evaluated using a two-tail t-test. RESULTS: Ten patients met the above criteria. The median age was 32 years with a range of 11-58 years. In comparing the semiquantitative uptake and the SUVs of FDG in the neck and paravertebral areas on the initial PET scan to the temperature-controlled PET scan, the mean decrease and the standard deviation of the decrease demonstrated a statistically significant decrease in with P values range from <0.02 to <0.001. CONCLUSION: Controlling the patient's environmental temperature prior to the dosing and during the uptake phase can significantly reduce FDG uptake in brown fat in the neck and paravertebral areas. Further studies are warranted to determine the most effective protocol to control the patient's environmental temperature in order to minimize brown fat uptake.

Combined carotid endarterectomy and myocardial revascularization: personal experience.

A significant percentage of patients undergoing myocardial revascularization suffer from extracranial cerebrovascular disease; recognition of such combined lesions identifies patients at risk for cerebrovascular accidents during the cardiac procedure. Simultaneous or staged coronary artery bypass graft (CABG) and carotid endarterectomy operations have been performed for the last 20 years, however, the clinical indications and the timing of the procedures remain controversial issues. Between November 1988 and January 1994, 1122 patients underwent myocardial revascularization at our Institute and in 35 cases (3.7%) carotid endarterectomy was simultaneously performed; 502 isolated carotid endarterectomies were performed in the same period. Trivascular coronary artery disease was found in 27 cases and low ejection fraction in six. Each patient received an average of 3.7 coronary grafts. Hospital mortality was 5.7% and major neurologic morbidity 2.8%. We believe that a simultaneous approach is recommended in patients with unstable angina and symptomatic carotid artery disease; in patients with a critical but asymptomatic carotid artery stenosis the indication for operation is subject to individual clinical judgment.
