This study aimed at testing human skin wound healing improvement by a 21-day supplementation of 1.0 g ascorbic acid (AA) and 0.2 g pantothenic acid (PA). 49 patients undergoing surgery for tattoos, by the successive resections procedure, entered a double-blind, prospective and randomized study. Tests performed on both skin and scars determined: hydroxyproline concentrations, number of fibroblasts, trace element contents and mechanical properties. In the 18 supplemented patients, it was shown that in skin (day 8) Fe increased (p < 0.05) and Mn decreased (p < 0.05); in scars (day 21), Cu (p = 0.07) and Mn (p < 0.01) decreased, and Mg (p < 0.05) increased; the mechanical properties of scars in group A were significantly correlated to their contents in Fe, Cu and Zn, whereas no correlation was shown in group B. In blood, AA increased after surgery with supplementation, whereas it decreased in controls. Although no major improvement of the wound healing process could be documented in this study, our results suggest that the benefit of AA and PA supplementation could be due to the variations of the trace elements, as they are correlated to mechanical properties of the scars.

The aim of this prospective and randomized study was to establish whether the use of fibrin glue was beneficial after axillary lymph node dissection. From January 1990 to January 1991, 40 women were randomized before surgery for breast cancer: 20 patients (group A) underwent vaporization of fibrin glue (Tissucol®, 5 ml of 500 IU thrombin) only in the area of axillary dissection; another 20 patients (group B) served as controls. The two groups were compared for age, number of nodes removed and involved, volume and duration of fluid drainage and complications. Student’s t test, Mann-Whitney nonparametric test and the χ² test were used when appropriate for statistical analysis. The two groups were well balanced for age, number of nodes removed and involved, staging and histologic findings. The average volume of lymphorrhea in the lymph node dissection area was greater after use of fibrin glue (410.4 ml) than in controls (275.5 ml, p = 0.016). No difference was noted between the two groups for the volume of drainage fluid of the site of mastectomy or lumpectomy, or for the total volume of drainage fluid. Drainage duration as well as duration of hospital stay were similar. Six complications occurred in group A, and one in group B (p = 0.037). In contrast to our expectations, fibrin glue does not improve the postoperative period after axillary lymph node dissection; its application seems to be followed by more complications than in controls, which could be explained by the proteolytic activity of the lymph, the use of quick-acting fibrin sealant and the formation of two fibrin films in the armpit before the end of the surgical procedure.

The use of somatostatin analogs is a new conservative therapeutic approach for the treatment of chyle fistulas developing after thyroid cancer surgery. The combination therapy with a total parenteral nutrition should avoid the high morbidity of are-intervention with an uncertain outcome. This promising trend is supported by the present case report of a chyle leak occurring after total thyroidectomy with central and lateral neck dissection for a papillary carcinoma, which was treated successfully without immediate or distant sequelae.
