Dental invasive procedures in von Willebrand disease outpatients treated with high purity FVIII/VWF complex concentrate (Fanhdi®): experience of a single center.

PURPOSE: To retrospectively assess the effectiveness and safety of customized hemostatic protocols using a plasma-derived, von Willebrand Factor (VWF)-containing Factor VIII concentrate (pdVWF/FVIII) in von Willebrand disease (VWD) patients undergoing dental invasive procedures. METHODS: Protocol for each patient was drawn up by the Blood Unit based on the VWD type, disease severity, and type of treatment. pdFVIII/VWF infusions and doses were registered at 30-60 min before intervention (t0) and at 12-24-36-48-72 h after intervention (t12-t72) and up to day 7. Any peri- or postoperative bleeding, complication or adverse event was registered. RESULTS: Forty-five dental procedures were performed on 20 VWD patients (six type-1, two type-2a, six type-2b, six type-3). Most pdFVIII/VWF infusions at t0 were 60 IU/kg (n = 7) and 50 IU/kg (n = 9). Subsequent infusions were mostly 30-50 IU/kg. No bleeding complications or adverse events were reported. CONCLUSION: This study supports the safety and efficacy of pdFVIII/VWF to prevent peri- and postoperative bleeding after invasive oral procedures.

Immediate breast reconstruction in the elderly: can it be considered an integral step of breast cancer treatment? The experience of the European Institute of Oncology, Milan.

BACKGROUND: In the last few decades, breast reconstruction often has not been offered to the elderly population due to the reluctance of clinicians concerned about serious co-morbidities. This study aims to demonstrate that breast reconstruction is feasible and safe in the elderly cohort. METHODS: Between 1999 and 2004, 63 elderly patients underwent an immediate reconstruction after breast cancer treatment at the European Institute of Oncology. A conservative treatment, combined with breast repair by plastic surgical techniques, was performed in 14 patients. In the remaining 49 patients, a modified radical mastectomy was necessary in 30 breasts, a total mastectomy in 19, a subcutaneous mastectomy in one case and a radical mastectomy in one patient. Three nipple-sparing mastectomies, along with intra-operative radiotherapy, were performed in two patients. A definitive silicone implant was used in 41 breasts and a skin expander in eight cases. A latissimus dorsi flap was performed in two patients, a pedicled transverse rectus abdominis muscle (TRAM) flap in two cases and a local advancement fasciocutaneous flap in another two patients. RESULTS: In all patients, surgery was well tolerated despite patient age. No systemic and medically unfavourable events occurred in the immediate and late postoperative period. Infection occurred in four patients (6.34%) and partial necrosis of the mastectomy flaps in three cases (5.5% of the mastectomies). Capsular contracture grade III and IV was reported in four cases (8.89%). Total implant removal was rated 12.24%, due to infection (three prostheses), exposure (one expander) and capsular contracture grade IV (two implants). CONCLUSIONS: Implant-based technique of breast reconstruction should be made available to the elderly population.

Ventilatory and hemodynamic management of potential organ donors: an observational survey.

OBJECTIVE: To determine the current standard ventilatory and cardiovascular management in potential organ donors. DESIGN: Prospective, multiple-center, observational survey. SETTING: A total of 15 intensive care units in 13 hospitals in Piedmont, Italy. PATIENTS: A total of 34 brain-dead patients enrolled in 6 months. MEASUREMENTS AND MAIN RESULTS: Demographics and reasons for lung transplant exclusion were recorded. Ventilatory and hemodynamic variables were compared before and after confirmation of brain death. A total of 23 potential donors were ineligible for lung donation based on pulmonary status and age. Of the 11 eligible lung donors, only two donated the lungs because five had Pao2/Fio2 ratios of <300 and four were ineligible for logistic problems. Tidal volume was 10 +/- 2 mL/kg, positive end-expiratory pressure was 3.3 +/- 2.7 cm H2O, Fio2 was 50% +/- 18% before brain death diagnosis, and no changes were made after brain death confirmation. In potential lung donors, apnea tests were performed with apneic oxygenation after disconnection from the ventilator in all cases; tracheal suction was performed with an open circuit in eight cases, and no recruitment maneuvers were performed. Crystalloid infusion was increased after diagnosis of brain death from 187 +/- 151 to 275 +/- 158 mL/hr (p < .05), and central venous pressure increased from 6 +/- 3 to 7 +/- 3 mm Hg (p < .05). Inotropic support was used in 24 donors (70%). CONCLUSIONS: Five of 11 potential lung donors (45%) had a Pao2/Fio2 ratio of <300, making them ineligible for lung donation. After the diagnosis of brain death, ventilatory management remained the same, no maneuvers for prevention of derecruitment of the lung were performed, and cardiovascular management was modified to optimize peripheral organ perfusion. These data represent the current standard of care for ventilatory management of potential organ donors and may be suboptimal in preserving lung function.

The "perfusion map" of the unipedicled TRAM flap to reduce postoperative partial necrosis.

The unipedicled transverse rectus abdominis musculocutaneous (TRAM) flap is a well-known technique for breast reconstruction. However, it is clinically difficult to evaluate the blood perfusion of the flap in the operating room. A new technique of blood supply evaluation, employing indocyanine green dye (ICG) fluorescence videoangiography has been performed in 10 cases of unipedicled TRAM flap breast reconstruction. In our series, the ICG measurement was demonstrated to be a safe, quick, and accurate technique of flap perfusion analysis. We confirmed the presence of individual pattern ("perfusion map") of the flap perfusion, zone II sometimes not being as well perfused as zone III. In this paper, we present our descriptive findings, and the ICG analysis seems to have a predictive value of unipedicled TRAM flap viability.
