Repair of a fistula between the bladder and the perineal skin by femoral gracilis flap interposition

Shuichi Osawa
Abstract The successful repair of a fistula between the bladder and the perineal skin using a femoral gracilis flap is reported. A 70-year-old woman, who 10 years previously had undergone a total hysterectomy for uterine cancer, developed a fistula between the bladder and the perineal skin after she underwent Mile's operation for rectal cancer. Initially, an attempt was made to repair the fistula by the transabdominal approach. This failed, probably because of the lack of supporting tissue between the bladder and the perineal skin. The second repair was performed with plastic surgeons. A secure three-layer bladder closure was accomplished. A right femoral gracilis flap was developed and rotated 180° to fill the defect in the skin and subcutaneous tissue. Four weeks after surgery, cystography revealed no fistula or urinary leakage and the drainage catheter was removed. Femoral gracilis flap interposition was successful for repair of a fistula between the bladder and the perineal skin when there was no supporting tissue due to extensive exenteration in the surgical removal of rectal cancer and after other repair procedures had been unsuccessful.

Differences in the allocation patterns between liana and shrub Hydrangea species

Abstract Allometric analysis of four Hydrangea species (Hydrangea petiolaris, Hydrangea paniculata, Hydrangea macrophylla var. megacarpa and Hydrangea hirta) was conducted to test the hypothesis that the liana species (H. petiolaris) invests more in leaves and reproductive organs than the shrub species. We calculated the allocation ratios of leaves, supporting tissues (trunks and roots) and reproductive organs. Hydrangea petiolaris differed markedly from the three shrubs in terms of trunk and root allocations, while leaf allocation was not statistically different. The C/F ratios (the ratios of the dry weights of non-photosynthetic organs to photosynthetic ones) of the four species ranged from 9 to 12, and were not statistically different. These results did not support the hypothesis. The biomass of H. petiolaris was up to 100-fold greater than the biomass of the three shrubs. The growth form of H. petiolaris would minimize allocation to supporting tissue and produce a large biomass. The biomass of reproductive organs of H. petiolaris was up to 700-fold greater than the biomass of the three shrubs. This advantage might, therefore, serve as a driving force for the evolution of lianas. [source]

An alternative method for splinting of traumatized teeth: case reports

Gülsün Yildirim Öz
Abstract,,, Injuries to the dentoalveolar complex are fairly common and can be caused by a number of reasons. There are many techniques for repositioning and stabilizing traumatically luxated or avulsed teeth. Many of the splinting techniques previously advocated were time-consuming. Not only were the splints difficult to fabricate and difficult to remove, they also contributed to injury of the soft and hard supporting tissues. Ribbond (Ribbond Inc., Seattle, Wash) is basically a reinforced ribbon which is made from ultrahigh molecular weight polyethylene fiber having an ultrahigh modulus. It is used in dentistry for various purposes. The use of Ribbond appears to be an adequate and easy method for stabilization and fixation. It can be used in the treatment of dental injuries. In this article the use of Ribbond for the treatment of dentoalveolar injuries is described. [source]

Esthetic Restoration of the Traumatized and Surgically Reconstructed Anterior Maxilla

ABSTRACT: A car accident victim can lose not only anterior teeth but also the soft- and hard-tissue support for these teeth. This article describes a step-by-step approach to the treatment protocol for an accident victim in whom anterior teeth and the supporting tissues have been lost. The protocol is systematic and can be used for most accident cases, where the functional and esthetic demands are very high. CLINICAL SIGNIFICANCE: This article demonstrates how excellent teamwork among the dentist, implant surgeon, and laboratory technician can result in a well-conceived and successful restoration following traumatic injury of the dentition.

Leaves of Lianas and Self-Supporting Plants Differ in Mass per Unit Area and in Nitrogen Content

PLANT BIOLOGY, Issue 3 2000
M. Kazda
Abstract: The aim of this study was to test the hypothesis that the reduction in supporting tissues in climbers compared to self-supporting plants is also true for their leaves, and that climbers generally require higher leaf nitrogen than self-supporting plants to accomplish fast growth. This hypothesis was tested using paired samples of both growth forms with assessment of leaf area index above the sampled plants (LAIa) in a tropical rain forest in Gabon. The sampling protocol ensured that within a highly fluctuating low canopy environment, the growth conditions were identical for each pair sampled. The results confirmed the hypothesis. Lianas had significantly lower leaf mass per unit leaf area (LMA) than their supporters. Liana leaves also contained significantly more nitrogen than host tree leaves. The differences in nitrogen concentration between liana and tree leaves reversed for the most shaded sites, when nitrogen was expressed on a leaf area base (Narea). Significant regression between leaf nitrogen and LAIa was found for the climbers on the shaded sites but not for their supporters. This indicated better acclimation of climbers to prevailing light conditions. Better nitrogen allocation at low LMA, together with lower carbon costs for building supporting tissues, makes lianas highly competitive, especially where high nitrogen availability is assured.
