Gemeinhardt First page of article [source] Unusual presentation of GLUT-1 positive infantile haemangiomaAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 2 2009Clare Koh ABSTRACT Infantile haemangiomas are usually not present at birth. This is a case of a female infant with an atypical congenital vascular tumour present at birth which ulcerated in the first few days of life, involuted over several months and showed histopathological features in keeping with either an involuting GLUT-1 positive infantile haemangioma or a reticular haemangioma of infancy. The initial clinical presentation was atypical for an infantile haemangiomas and for a congenital haemangioma, however the histopathology and immunohistochemistry assisted with confirmation of the diagnosis. Vacuum-assisted closure (VAC) therapy aided in the complete healing of the ulcerated infantile haemangioma which was not achievable with conventional dressings. [source] Comparative analysis of global gene expression profiles between diabetic rat wounds treated with vacuum-assisted closure therapy, moist wound healing or gauze under suctionINTERNATIONAL WOUND JOURNAL, Issue 5 2008Kathleen L Derrick Abstract How differential gene expression affects wound healing is not well understood. In this study, Zucker diabetic fatty (fa/fa) male inbred rats were used to investigate gene expression during wound healing in an impaired wound-healing model. Whole genome microarray surveys were used to gain insight into the biological pathways and healing processes in acute excisional wounds treated with vacuum-assisted closure (V.A.C.®) Therapy, moist wound healing (MWH) or gauze under suction (GUS). Global gene expression analyses after 2 days of healing indicated major differences with respect to both number of genes showing fold changes and pathway regulation between the three different wound treatments. Statistical analysis of expression profiles indicated that 5072 genes showed a >1·6-fold change with V.A.C. Therapy compared with 3601 genes with MWH and 3952 genes with GUS. Pathways and related genes associated with the early phases of wound healing diverged between treatment groups. For example, pathways involving angiogenesis, cytoskeletal regulation and inflammation were associated with elevated gene expression following V.A.C. Therapy. This study is the first to assess wound healing by whole genome interrogation in a diabetic rat model treated with different healing modalities.

Marathe MD Abstract Objectives/Hypothesis: The objective was to describe a novel technique for reconstructing the cranial vertex without the use of free tissue transfer. Study Design: Case report, literature review, and discussion. Methods: A 50-year-old woman presented from a remote Pacific Island community with a 12 × 14-cm, necrotic, grossly contaminated eccrine gland carcinoma of the cranial vertex that extended through the calvarium but did not invade the dura. Following tumor extirpation, the resulting bony defect was 10 × 12 cm in size, with a concomitant scalp defect of 14 × 16 cm. Free tissue transfer was impossible because of severe intimal peripheral vascular disease, posing a challenging reconstructive dilemma. After tumor resection, the bony edges were covered with local scalp flaps and the vacuum-assisted closure device was placed over the wound at a constant setting of ,50 mm Hg. The vacuum-assisted closure device was changed three times per week for 3 weeks. Results: A thick, 1-cm bed of granulation tissue developed over the dura, allowing temporary coverage by a split-thickness skin graft, and the scalp defect decreased in size by approximately 25%. The patient did not develop meningitis, headache, or localized infection as a result of placement of the vacuum-assisted closure device and tolerated the vacuum-assisted closure well. After a requisite period of healing, tissue expanders and calvarial reconstruction will be performed. Conclusion: Use of the vacuum-assisted closure device is a safe, reliable adjunct in the closure of large cranial defects with exposed dura and offers a novel reconstructive option for complex defects of the head and neck.
