Many flaps have been described and are being used in the reconstructionof extensive tissue defects in the thoracic wall. Theextended cutaneous thoracoabdominal flap, described in 2006,is an excellent option for chest wall reconstruction in patientswith advanced breast cancer, being associated with a low morbidityrate and good functional results. The main disadvantageof this technique is the poor cosmetic outcome and the completeabsence of a breast crease. We present the first case of atwo-stage heterologous breast reconstruction after reconstructionusing an extended cutaneous thoracoabdominal flap.

Background In all branches of medicine, it is the surgeon’s responsibility to provide the patient with accurate information before surgery. This is especially important in cosmetic surgery because the surgeon must focus on the aesthetic results desired by the patient. Methods An experimental protocol was developed based on an original questionnaire given to 72 patients. The nature of the responses, the patients’ motivation and expectations, the degree of patient awareness regarding the planned operation, and the patients’ perceptions of the purpose of the required consent for cosmetic surgery were all analyzed using Fisher’s exact test. Results Candidates for abdominal wall surgery had significantly more preoperative psychological problems than their counterparts did (P=0.035). A significantly different percentage of patients under 40 years of age compared to those over 40 years of age searched for additional sources of information prior to the operation (P=0.046). Only 30% of patients with a lower educational background stated that the preoperative information had been adequate, whereas 92% of subjects with secondary schooling or a postsecondary degree felt that the information was sufficient (P=0.001). A statistically significant difference was also present between patients according to their educational background regarding expected improvements in their quality of life postoperatively (P=0.008). Conclusions This study suggests that patients require more attention in presurgical consultations and that clear communication should be prioritized to ensure that the surgeon understands the patient’s expectations.

4f occupancy and magnetism of rare-earth atoms adsorbed on metal substrates

<P>We report x-ray absorption spectroscopy and x-ray magnetic circular dichroism measurements as well as multiplet calculations for Dy, Ho, Er, and Tm atoms adsorbed on Pt(111), Cu(111), Ag(100), and Ag(111). In the gas phase, all four elements are divalent and we label their 4f occupancy as 4f(n). Upon surface adsorption, and depending on the substrate, the atoms either remain in that state or become trivalent with 4f(n-1) configuration. The trivalent state is realized when the sum of the atomic correction energies (4f -> 5d promotion energy E-fd + intershell coupling energy delta E-c) is low and the surface binding energy is large. The latter correlates with a high substrate density of states at the Fermi level. The magnetocrystalline anisotropy of trivalent RE atoms is larger than the one of divalent RE atoms. We ascribe this to the significantly smaller covalent radius of the trivalent state compared to the divalent one for a given RE element. For a given valency of the RE atom, the anisotropy is determined by the overlap between the spd states of the RE and the d states of the surface. For all investigated systems, the magnetization curves recorded at 2.5 K show absence of hysteresis indicating that magnetic relaxation is faster than about 10 s.</P>
