A transformative shift in urban ecology toward a more active and relevant future for the field and for cities.

This paper builds on the expansion of urban ecology from a biologically based discipline-ecology in the city-to an increasingly interdisciplinary field-ecology of the city-to a transdisciplinary, knowledge to action endeavor-an ecology for and with the city. We build on this "prepositional journey" by proposing a transformative shift in urban ecology, and we present a framework for how the field may continue this shift. We conceptualize that urban ecology is in a state of flux, and that this shift is needed to transform urban ecology into a more engaged and action based field, and one that includes a diversity of actors willing to participate in the future of their cities.

Accuracy of early burn depth assessment by laser Doppler imaging on different days post burn.

Background: Accurate diagnosis of burn depth is essential in selecting the most appropriate treatment. Early assessment of burn depth by clinical means only has been shown to be inaccurate, resulting in unnecessary operations or delay of grafting procedures. Laser Doppler imaging (LDI) was reported as an objective technique to determine the depth of a burn wound, but the accuracy on very early days post burn has never been investigated yet.

Autologous in vivo adipose tissue engineering in hyaluronan-based gels--a pilot study.

Background: There is a major clinical need for strategies for adequately reconstructing the soft tissue defects found after deep burns, tumor resection, or trauma. A promising solution is adipose tissue engineering with preadipocytes, stem-cell derived precursors of the adipose tissue, implanted within biomaterials. This pilot study evaluated hyaluronan gels mixed with autologous undifferentiated preadipocytes in a pig model for their potency to generate new fat.

A simple new technique for neo-umbilicoplasty.

This article describes a new technique for reconstruction of the umbilicus. The technique used simply originated from a few clinical cases in which we were confronted with an absent or destroyed umbilicus. Previously described techniques for neo-umbilicoplasty were unsatisfying or seemed too complex in our hands.

Do pre-operative abdominal exercises prevent post-operative donor site complications for women undergoing DIEP flap breast reconstruction? A two-centre, prospective randomised controlled trial.

The deep inferior epigastric perforator (DIEP) flap is the gold standard for breast reconstruction using abdominal tissue. Unlike the transverse rectus abdominis myocutaneous (TRAM) flap, no rectus abdominis muscle is removed with the flap, but intra-muscular scarring can still cause post-operative complications. Strong abdominal muscles have been advocated as a prerequisite for surgery, but without any evidence as to the potential benefits.

Better cosmetic results and comparable quality of life after skin-sparing mastectomy and immediate autologous breast reconstruction compared to breast conservative treatment.

Preoperative chemotherapy (PCT) can be used in large primary breast cancer to facilitate breast conservative surgery (BCS). Cosmetic results of BCS are influenced by the size of the residual tumour, relative to the size of the breast. After mastectomy, immediate breast reconstruction (IBR) with autologous tissue provides excellent cosmetic outcome and has proven to be safe in breast cancer patients.

Evaluation of nipple-areola complex sensitivity after the latero-central glandular pedicle technique in breast reduction.

Introduction: Previous anatomical and clinical studies have shown that nipple-areola sensitivity decreased significantly after conventional superior and inferior pedicle technique for 3-6 months postoperatively. We found it necessary to modify our techniques in breast reduction to achieve a better outcome regarding breast sensation. Since 1999, we have been using a new technique of breast reduction with a latero-central glandular pedicle.

The latero-central glandular pedicle technique for breast reduction.

The relatively high number of complications and disadvantages of the conventional techniques in breast reduction combined with our expertise in restoring sensation in breast reconstructive procedures, led to the development of a new technique that was crystallised from the traditional techniques and is able to overcome most of their disadvantages. The key issue of the technique is that the nipple is vascularised and innervated on a column of glandular tissue that remains in contact in its posterior part with the pectoralis muscle and its perforators and in its lateral aspect to the lateral pillar of breast tissue. Due to the ptosis that develops during the process of hypertrophy, this column will gain sufficient length to be turned upwards into the new position of the nipple.

A 25-year study of emergency surgical admissions.

Background: Numbers of emergencies are increasing, but no comprehensive data are available for emergency surgical admissions. This study documents the changes over 25 years in a district general hospital.

Methods: Details of all general surgical (including urological) emergency admissions were analysed for every fourth calendar year from 1974 to 1998.

[Surgical management of complete Tossy III acromioclavicular joint dislocation with the Bosworth screw or the Wolter plate. A critical evaluation].

The long-term results with an average of 4.3 years of 87 patients with an AC-dislocation grade III according to Tossy, treated operatively with a Bosworth screw or a Wolter plate are described and submitted to critical evaluation. Of the patients 16% had implant failures.
