    Abstract Introduction: Mastectomy skin flap necrosis (MSFN) has a reported incidence of 5%-30% in the literature. It is often a significant and underappreciated problem. The aim of this article was to review the associated challenges and possible solutions.
    Methods: A MEDLINE search was performed using the search term "mastectomy skin flap necrosis". Titles and abstracts from peer-reviewed publications were screened for relevance.
    Results: MSFN is a common complication and may present as partial- or full-thickness necrosis. Predictive patient risk factors include smoking, diabetes, obesity, radiotherapy, previous scars and severe medical comorbidity. MSFN leads to a number of challenges, including wound management problems, delays to adjuvant therapy, esthetic compromise, implant extrusion, patient distress and financial loss. Careful preoperative planning and meticulous surgical technique may reduce the incidence of MSFN. A number of intraoperative techniques are available to try and predict skin flaps at risk of MSFN. MSFN may be managed operatively or nonoperatively. Early intervention may reduce the morbidity of MSFN in selected cases. Topical nitroglycerin ointment may be beneficial in reducing MSFN following immediate reconstruction, but the evidence base is still limited.
    Conclusion: MSFN can result in considerable challenges for the patient and the health care service. This review discusses the management options for this problem.

    Abstract Purpose: We describe a modification of the two-stage laparoscopic Fowler-Stephens technique in which the gubernacular vessels are preserved and the testis is brought down the canal via the internal ring. A purely laparoscopic second stage is performed. We report our outcomes with this technique.
    Materials and methods: All laparoscopic Fowler-Stephens orchidopexies undertaken at our hospital from 1996 to July 2004 were identified from a prospectively collected database of all surgical procedures undertaken in the unit. A retrospective case-note review was undertaken.
    Results: We identified 21 patients, 4 bilateral and 17 unilateral, giving a total of 25 intra-abdominal testes. Mean age at presentation was 21 months (range, 0-56 months). Mean age at the first stage was 36 months (range, 11-68 months). The testis position at initial laparoscopy was high in 5, close to the internal inguinal ring in 9, peeping in 6, and pelvic in 5. The testis size at this stage was either normal, good sized, or reasonable sized in 15, small or dysplastic in 5, and in 5 the size was not commented upon. The testicular vessels were mainly divided by diathermy at the first stage, but in 6 the vessels were clipped. The second stage was undertaken 6 months after the first, in order to allow the collateral blood supply to adapt. Twelve testes had changed position category during this interval, 2 having ascended to a higher position and 10 descended to a lower position; 12 were in the same position at both stages; and in 1 case the position was not commented upon at the second stage. A purely laparoscopic second stage technique was used in 21 cases; an assisted-open second stage was undertaken in 1 case. In 3 cases the testis was palpable in the groin at examination under anesthesia and so an open second stage orchidopexy was performed. Follow-up was at 6 and 18 months after the second stage. Eighteen of the 21 testes that underwent a purely laparoscopic second stage survived at 6 months, giving a success rate with this technique of 86%. The overall testis survival rate in the entire group at 6 months was 88% (22/25). Findings in those patients reviewed at 18 months were unchanged.
    Conclusion: The two-stage laparoscopic Fowler-Stephens orchidopexy, with preservation of the gubernacular vessels and predominantly using a purely laparoscopic second stage, provided a very good testis survival rate, approaching 90%.

  4. Article ; Online: The spleen--a potential source of new islets for transplantation?

    Abstract Background/purpose: Islet transplantation offers the potential to reverse diabetes soon after diagnosis and has achieved considerable success in adults. Its use in children has been limited by long-term immunosuppression requirements and donor pancreas shortages. An ideal alternative source of islets would be from autologous precursor cells. The aim of this study was to determine whether the spleen can produce insulin-producing cells (IPCs) in our established model of pancreatic development.
    Methods: Embryonic quail spleens (day 4.5) and chick pancreatic epithelium (day 4) were microdissected and recombined in a ratio of 1:1 (n = 12), 2:1 (n = 9) and 2:2 (n = 5). They were cultured for 7 days, sectioned, and analysed by fluorescent immunochemistry. Controls were performed to ensure clean separation.
    Results: Overall, 12 (46%) of 26 recombinants contained IPCs of splenic origin, occurring in 5 (42%) of 12 of the of 1 spleen-1 epithelium recombinants, 3 (33%) of 9 of the 2 spleen-1 epithelium recombinants, and 4 (80%) of 5 of the 2 spleen-2 epithelia recombinants. Controls were negative.
    Conclusions: Preliminary results suggest developing avian spleens can differentiate into IPCs. Increased tissue mass enhanced the likelihood of this occurring. Mesenchyme-to-epithelia ratio did not influence this. The spleen could be an ideal autologous islet source for transplantation in children.

    Abstract A previously fit and well 14-month-old-girl presented with a 2-month history of worsening cough and wheeze. Chest radiograph revealed a widened mediastinum and thoracic CT showed a large mixed density mass in the superior mediastinum, consistent with a mediastinal teratoma. Her tumor markers were within the normal range. The mass was resected and found to be a mature cystic teratoma. Surprisingly, well-formed bowel-like structures were present, containing all bowel wall layers and having a ganglionated myenteric plexus. The identification of complete sections of bowel in this context is a rare finding and to the best of our knowledge has not been published previously for the mediastinal teratoma. The possibility of secondary neoplasia developing in these areas is a complicating factor.

    Abstract Background/purpose: beta-Cell replacement offers a potential cure for type 1 diabetes mellitus in children. We have previously shown that stomach mesenchyme (SM) is competent to derive islet tissue by mesenchymal-to-epithelial transition (iMET). The aim of this study was to further characterize the developmental fate of this SM in the presence of pancreatic epithelia (PE) in SM/PE recombinants. The homeobox ISL-1 was examined in these recombinants because this gene is restricted to the dorsal pancreatic mesenchyme and endocrine cells in early pancreatic development.
    Methods: Chick-quail recombinants of SM + PE (n = 15) and whole stomach controls (n = 8) were cultured for 7 days. In addition, organ blocks were examined after normal development at days 4 to 10 (n = 4 for each stage). Tissues were analyzed using immunochemistry against quail-specific antigen and ISL-1.
    Results: Thirteen of 15 SM + PE recombinants expressed the ISL-1 protein in cells from SM origin. Nine of 15 of these recombinants showed iMET and coexpression of insulin, and ISL-1 was recorded.
    Conclusions: Pancreatic epithelium is able to reprogram SM to a more caudal pancreatic fate when cocultured. Islet tissue by mesenchymal-to-epithelial transition observed in recombinants showed coexpression of insulin and ISL-1. These experiments are important to identify the molecular mechanisms behind iMET for potential therapeutic use for treating children with diabetes.
