Growth factor expression with different wound treatments after laser resurfacing.

Background: Many studies have demonstrated that the specific method of wound dressing used may affect the healing process. However, the effect of the method of wound dressings on the expression of growth factors is not well documented.

Objective: The aim of this study was to evaluate the effects of different methods of treatment on the healing process and the expression of growth factors (epidermal growth factor, basic fibroblast growth factor, transforming growth factor-beta(2) [TGF-beta(2)], platelet-derived growth factor-A, and platelet-derived growth factor-B) by histologic study, immunohistochemistry, and reverse transcription-polymerase chain reaction.

Unusual sites of colorectal cancer metastasis.

We present 2 separate cases of adenocarcinoma of the colon with metastasis to the chin and the bladder, both of which are unusual sites of colorectal cancer metastasis. Patient 1 is a 77-year-old man who was diagnosed with adenocarcinoma of the colon, American Joint Committee on Cancer (AJCC) T4 N0 M0 (stage II), and underwent a right hemicolectomy. Fourteen months later he developed a firm 2.

The optimal sequence of microvascular repair during prolonged clamping in free flap transfer.

During free flap transfer, the surgeon may decide to begin with repair of the artery or the vein(s) and to unclamp the first vessel as soon as repair is completed or maintain the clamping of both vessels until completion of all repairs. Complications can lead to prolonged clamping times, potentially increasing the risk of tissue ischemia, vascular damage, and thrombosis. The goals of the present study were to determine whether the sequence of vessel repair and the duration of clamping affect the success of free flap transfer in cases requiring prolonged clamping.

Management of small bowel adenocarcinoma.

Small bowel adenocarcinoma is a relatively rare malignancy. Only limited information is available on the incidence, prognosis, and role of chemotherapy in the treatment of this disease. We present a review of currently available clinical data to assist the practicing oncologist in the treatment of these patients.
